As the twentieth century draws to a close there appears to be a consensus that teacher training can be delivered virtually using the Internet. Three EC funded international projects (T3, REM and TRENDS) have demonstrated that this is practical and there are other examples around the world. However, such-modes of teacher training are challenging and appear to require considerable re-engineering of educational processes as well as information and communication technologies. This paper discusses these challenges by focussing on the experience of a group of Portuguese student teachers and their tutor within the multinational EUMedea course.
The EUMedea Project was a teacher training on-line course of the T3 Project Telematics for Teacher Training about ‘Environmental Education’. It involved 11 groups of teachers/student teachers from five European countries: United Kingdom, Portugal, Italy, Finland and Holland. The aims of the course were: to designing environmental education project; use Internet to find information, share knowledge and co-operate in designing environmental education projects; use a Computer Mediated Communication (CMC) environment to work with other teachers co-operatively. This paper will present the results, discussions and reflections of the group of Castelo Branco (Portugal). The results of this experimental course will be an opportunity to reflect and propose several insights and clues for the future use of Internet on teacher training.
Paratuberculosis or Johne's disease, caused by Mycobacterium avium subsp. paratuberculosis (Map), is a chronic granulomatous enteritis affecting both domestic and wild ruminants. The present work is part of a wider set of studies designed to assess the prevalence of paratuberculosis in free ranging red deer (Cervus elaphus). With that purpose, 877 free-ranging red deer legally hunted in the Centre-eastern Portugal were submitted to necropsy and sampled for molecular methods, microbiology and histopathology. Thirty-seven (4.2%) kidneys revealed acid-fast bacilli when screened with the Ziehl-Neelsen technique. Map was detected by IS900 polymerase chain reaction (PCR) in thirty (81.1%) of the Ziehl-Neelsen positive kidneys. Subsequent PCR and/or culture from the different organs of the 37 examined animals allowed us to detect 86.4% (32 animals) infected red deer. Our results suggest that renal involvement in Map infected deer may be underdiagnosed and thus the routine examination of this organ and its inclusion in PCR techniques designed for Map detection could substantially improve the diagnostic of paratuberculosis in red deer.

This paper discusses the importance of the info-exclusion/info-inclusion of elderly people. Recently several initiatives taken from the EU encourage the info-inclusion of all the European citizens in special women, unemployed, and the elderly people. A problem related to the participation of older people in learning activities is that learning is traditionally often designed for younger people’s learning needs and skills. As our societies become older, a shift needs to be made towards older audiences in older to integrate them with younger generations. But the problem is that educational solutions rarely address the interests and specific needs of older people. Our conviction is that ICT can help elderly people to improve quality of life, stay healthier and live independently for longer. Portugal also launched several initiatives regarding the info-inclusion but as like the other countries some obstacles must be overcome and some proposals for the future will be presented.
Roles are not a new concept, but they have been used in two different ways: as modeling concepts in a static view and as instance extensions in a dynamic view. For these views only the dynamic offers supporting languages. The static view, although proving the utility of roles in modeling, does not offer a programming language that allows developers to use roles all the way from modeling to programming. We try to overcome this by presenting our role language JavaStage, based on the Java language. We do this by designing and implementing a simple framework and then compare the results with its OO equivalent. Our results show that static roles are in fact useful when used in code and that JavaStage features expand role reuse.
The work presented in this paper is part of an ongoing research project at the University of Coimbra IMPACTFIRE PTDC/ECM/110807/2009, which the main focus is the characterization of the behaviour of bolted steel connections subjected to accidental loads, such as impact and fire. Detailed description of the experimental parts developed, designed and fabricated at University of Coimbra, to carry out tests under high rates of loading is presented. This experimental part is operated by high pressure nitrogen comprising three main components: pneumatic reservoir, pneumatic cylinder and a rapidly opening valve, which allows the instantaneous nitrogen flow from the reservoir to the cylinder. Furthermore, the data acquisition system, the methodology for analysis of the results and the results of preliminary tests are also reported.
The increasing use of visual information in the new media brought to the color a new and relevant role. Inter
alia, the color is fundamental in discriminating the contents, providing the global understanding of things. However,
some people have a visual impairment designated color vision defective (CVD), which restrains the vision
of color in a proper way, so compromising the correct perception of the visual contents.
In order to overcome the referred handicap, on this article is proposed an algorithm which can be used to adapt
the color to dichromats to improving the way they see the images. Consequently, the images become more readable
and the discernment and comprehension of its components is enhanced.
In Portugal we are facing a fast decrease in the production of good quality wool. This situation can be seen from a qualitative and quantitative point of view by looking at the most extreme situation, which involves almost the extinction of a Merino breed - Merino Beira Baixa (MBB)- due to its inability to produce high milk quantities when subjected to the better hadling of the more intensive production systems. The changes in the production systems and the need for higher milk production for the production of PDD cheese (Protected Designation of Origin - EEC Regulation 2081/92), but without indexation to the milk of the MBB sheep breed (as opposite to other cheeses made exclusively with milk from one specific breed), has led to the massive introduction of extotic sheep breeds specialising in milk production. In the last decade, the MBB animals have decreased by more than 90%, and urgent actions is needed to prevent the disappearance of one more indigenous breed.
A new report from the Food and Agriculture Organization of the United Nations (Steinfield et al., 2006) considers lives¬tock production as one of the major causes of the world's most pressing environmental problems. To optimize the rumen mi¬crobial system, feeds must be characterized according to their ingestive and degradation behaviour in the rumen (Tammin¬ga, 1996). Improving the efficiency of feed nitrogen (N) uti¬lization is the most effective means to reduce nutrient losses (Jonker et al., 2002). The challenge is to establish the minimal amount of protein required by dairy cows to achieve optimal, but not necessarily maximal, milk production.
This study was designed to investigate the minimal request of N for normal microbial growth using in vitro gas produc¬tion technique, in different feedstuffs. As well as, the effects of different levels of N on the in vitro fermentation kinetics.
Food safety and eradication of food waste are current concerns of society and governments due to health, ethics, and sustainable economics. There are multiple technologies for monitoring food safety at different chain stages, among them, time-temperature integrators (TTI). Temperature is a major factor affecting food quality and safety during its life cycle. This parameter can be monitored using TTI devices on food packages, allowing users to know the thermal exposure. This chapter addresses food safety issues, namely factors related to microbial growth responsible for food deterioration. Moreover, TTI monitoring technologies are also described, focusing on features, advantages, disadvantages, applicability, and product examples. Analysis of the current state of TTI and technological evolution, a prediction is provided for future TTI devices designed for more assertive, traceable, safe, and quality food products.
This paper describes some successful experiences within engineering departments where emerging paradigms have been used to improve student’s know-how. This experience has resulted in students with high skills in fields of high acceptance in the employment market and with experience to deal within multi-disciplinary working teams.
Aspects of a case study that has involved the collaboration and supervision of staff from institutions of two countries (UK and Portugal) are reported.
The work included the programming and application of handheld devices as the human-machine interface. The designed machines are mechatronic devices, to be used in Domotic (Domestic Robotic) tasks. The main focus of this paper involves the pedagogical experience, since the technical features have already been published.
A realização de um Desfile de Moda é, tal como refere Dillon (2012) uma atividade que exige um esforço muito elevado da equipa que o produz e absorve muito tempo e comporta elevados custos. Se, por um lado, se trata de uma perfeita simbiose entre diversas áreas que trabalham, em conjunto, para um mesmo fim, por outro lado, exige a garantia de sucesso que advém da relação entre todas as partes intervenientes, o que só se consegue com um relacionamento eficaz na equipa.
A complexidade que um Desfile pode implicar na sua organização, quando resulta numa atividade de grande sucesso, representa retorno e identifica-se com enormes potencialidades para todas as partes envolvidas, desde a entidade que o realiza (designer, marca, instituição ou outra) ao público que assiste e participa e absorve todo um vasto conjunto de sensações que lhe são proporcionadas em diversos níveis, visual, estético, audiovisual, multimédia, som/música, espaço, etc.
For conventional cyclic prefix (CP)-assisted single-carrier/frequency-domain equalization (SC/FDE) implementations, as well as for orthogonal frequency-division multiplexing (OFDM) implementations, the CP length is known to be selected on the basis of the expected maximum delay spread. Next, the data block size can be chosen to be large enough to minimize the CP overhead, yet small enough to make the channel variation over the block negligible. This paper considers the possibility of reducing the overall CP assistance, when transmitting sequences of SC blocks, while avoiding an excessively long fast Fourier transform window for FDE purposes and keeping good FDE performances through low-complexity, noniterative receiver techniques. These techniques, which take advantage of specially designed frame structures, rely on a basic algorithm for decision-directed correction (DDC) of the FDE inputs when the CP is not long enough to cope with the time-dispersive channel effects. More specifically, we present and evaluate a novel class of reduced-CP SC/FDE schemes, which takes advantage of a special frame structure for replacing "useless" CP redundancy by fully useful channel coding redundancy, with the help of the DDC algorithm. When using the DDC-FDE technique with these especially designed frame structures, the impact of previous decisions, which are not error-free, is shown to be rather small, thereby allowing a power-efficiency advantage (in addition to the obvious bandwidth-efficiency advantage) over conventional block transmission implementations under full-length CP. Additionally, the DDC algorithm is also shown to be useful to improve the power efficiency of these conventional implementations.
Technology is a valuable tool in education both to increase access to knowledge and to promote
learning. On the one hand, the ability of ICTs to centralize and organize large amounts of knowledge
and, on the other hand, the students' familiarization with information networks and the internet, aims to
interconnect students in networks and learning communities. Much has been studied about how
spaces should be designed to enhance this type of learning. New learning environments are being
built from scratch, others are simply altered or reformulated to respond to changes in pedagogical
styles to incorporate ICT. In an age where the real and the virtual coexist, the learning spaces must be
designed and adapted to concretize these realities. In this study I will present the main premises that
should support the construction or transformation of several specific Learning Spaces to make
possible the existence of two worlds, the real and the virtual. In this context, we propose three new
variables that parallel technology will play a key role in the future learning space, (i) Time, (ii) Space,
(iii) Activity. If we consider that the occupation of a Learning Space implies available time and if
learning is not fixed by time or place, we find that the learning space needs a conjugation between
space and time. Higher Education Institutions have to be more efficient in the use of time, where
different times may have different learning experiences with different conjugations. Effective learning
involves Time, Space and Activity that is developed within it, which distinguishes it from other spaces.
A new experiment is suggested using those new variables to elucidate the construction of High Quality
Learning Environments.
Soil erosion by water is considered one of the processes leading to land degradation, affecting soil fertility, and consequently the loss of production capacity. According to recent studies, the projected increase of soil loss rate in the next few decades in European Union agricultural areas is about 22.5%. In Portugal and other countries in the Mediterranean basin, under a climate pattern unfavorable to maintaining an effective soil cover, and many times with rainfall peak events, an increase in soil erosion rates in climate change scenarios is expected. The main goal of this study is to evaluate the present and project the future rate of soil erosion in the Portuguese part of the Tagus International Transboundary Biosphere Reserve, located in the central-eastern part of Portugal, and the surrounding area, where agricultural use and livestock grazing are dominant. The soil loss calculation was performed for the present situation and projected for 2050, considering two Representative Concentration Pathways (RCP 4.5 and RCP 8.5). We used the Revised Universal Soil Loss Equation (RUSLE) methodology to model water soil erosion. The projected total annual rainfall will decrease for both RCP, however, the erosivity index increased in both future scenarios. Our findings provide insights into how future scenarios of socioeconomic development will affect soil erosion by water. Improving knowledge of the future rates of soil erosion is important for designing pol-icy instruments to mitigate the future impact of climate change on water erosion. The results of this study provide insights into how future scenarios of socioeconomic development, and changes in rainfall patterns, will affect soil erosion by water. Understanding better the soil erosion process, by using modeling tools and others, it´s very important for designing policy instruments to prevent the future impact of climate change on soil erosion.
El envejecimiento de la población es un hecho cada vez más observable en varios países desarrollados, como Portugal. Esta fase de la vida conduce a pérdidas biológicas y, a veces, a otros problemas psíquicos y sociales, lo que conduce a una disminución de la calidad de vida en esta edad. El presente estudio tuvo como objetivo verificar si los mayores, practicantes de un programa regular de actividad física formal tienen una mejor percepción de su calidad de vida que los mayores, no practicantes. La muestra consistió en 64 ancianos (n = 64), residentes en Proença-a-Nova, divididos en dos grupos, uno que designamos a grupo de practicantes con 32 individuos que participan en los programas de hidrogimnasia y gimnasia sénior, y otro con 32 elementos designados por grupo de no practicantes, que incluían individuos
que no practicaban actividad física formal. La calidad de vida percibida se midió utilizando el cuestionario MOS SF-36v2. Los resultados revelaron que la percepción de la calidad de vida tiende a ser mayor en los practicantes de actividad física, pero solo presenta diferencias estadísticamente significativas en las dimensiones de la función física, la función social y en el elemento de cambio en la salud, presentando valores más altos para el grupo de practicantes.
A moda, muitas vezes, é vista como algo fútil, direcionada a pessoas frívolas e abastadas. Contudo, cada vez mais, a moda toma ca-minhos que levam ao consumo consciente, à responsabilidade social e, acima de tudo, à inclusão social. A marca Milena Fernandes nasce em tempos de consciência e inclusão, em tempos de compartilhar valores positivos e de cultivar a alma por meio de seu propósito. O objetivo do presente artigo é descrever o processo, a criação e o desenvolvimento de uma marca de moda com propósito, bem como, sua primeira coleção, direcionada a todas as mulheres, mas que oferece alterna-tivas para aquelas que lutam contra o cân-cer, que perderam o cabelo e/ou realizaram mastectomia radical. A metodologia utilizada para este estudo foi a qualitativa exploratória (Gil, 2010) e os instrumentos foram: pesqui-sa bibliográfica (Stumpf, 2015), pesquisa de internet (Yamaoka, 2015) e estudo de caso (Duarte, 2015). Já para a criação da mar-ca, utilizamos a metodologia de construção de marcasmutantes (Kreutz, 2012). Como resultados, podemos ar que a moda é muito mais do que aexploração estético--mercadológica; ou seja, ela deve fazer sentido para as pessoas; por isso, os designers de moda devem repensar o seu papel na sociedade e atuar em prol dela.

The soil loss calculation was performed for the present situation and projected for 2070, considering two Representative Concentration Pathways (RCP 4.5 and RCP 8.5). We used the Revised Universal Soil Loss Equation (RUSLE) methodology to model the water soil erosion. For future scenarios, the change in rainfall patterns and the land cover modification were considered based on a set of drivers using the Patch-generating Land Use Simulation (PLUS). The future land cover patterns resulting from the PLUS model didn´t show significant changes for the studied period. The projected total annual rainfall will decrease for both RCP, however, the erosivity index increased in both future scenarios. Our findings provide insights into how future scenarios of socioeconomic development will affect soil erosion by water. Improving knowledge of the future rates of soil erosion is important for designing policy instruments to mitigate the future impact of climate change on water erosion. The results of this study provide insights into how future scenarios of socioeconomic development, and change in rainfall patterns, will can affect soil erosion by water.

Vehicular Delay-Tolerant Networking (VDTN) was proposed as a new variant of a delay/disruptive-tolerant network, designed for vehicular networks. These networks are subject to several limitations including short contact durations, connectivity disruptions, network partitions, intermittent connectivity, and long delays. To address these connectivity issues, an asynchronous, store-carry-and-forward paradigm is combined with opportunistic bundle replication, to achieve multi-hop data delivery. Since VDTN networks are resource-constrained, for example in terms of communication bandwidth and storage capacity, a key challenge is to provide scheduling and dropping policies that can improve the overall performance of the network. This paper investigates the efficiency and tradeoffs of several scheduling and dropping policies enforced in a Spray and Wait routing scheme. It has been observed that these policies should give preferential treatment to less replicated bundles for a better network performance in terms of delivery ratio and average delivery delay.
In Portugal, we are facing a fast decrease in the production of good quality wool. This situation can be seen from
a qualitative and quantitative point of view by looking at the most extreme situation, which involves almost the
extinction of a Merino breed – Merino Beira Baixa (MBB) – due to its inability to produce high milk quantities
when subjected to the better handling of the more intensive productions systems.
The changes in the production systems and the need for higher milk production for the production of PDO
cheese (Protected Designation of Origin – EEC Regulation 2081/92), but without indexation to the milk of the
MBB sheep breed (as opposite to other cheeses made exclusively with milk from one specific breed), has led to
the massive introduction of exotic sheep breeds specialising in milk production. In the last decade, the MBB
animals have decreased by more than 90%, and urgent action is needed to prevent the disappearance of one more
indigenous breed.
From the perspective of:
• Merino wool produced, it is possible to see a large quantitative decrease; the quality has decreased
enormously, and nowadays is very difficult to find, in the breed, fine wool animals;
• the productive system, we should emphasise that it is still possible to find farms with extensive systems.
However, the profitability of the traditional system based on the MBB is becoming minimal, and the system
could disappear if attention is not given to its conservation; and
• environmental protection, the disappearance of traditional extensive systems and the reduction of
biodiversity are worrying.
The guided decisions to an understanding of the nature of the science demand a real understanding of the History and Philosophy of Science. Starting with the analysis of the basic proposals of the recent Portuguese curricular reform, which is in a phase of declining enthusiasm due to the ineffectiveness of the changes in teaching classrooms, the study has been put into the framework of the New Philosophy of Science. The main hypothesis of the study was that, to carry out Teacher Education, exploring action-research perspectives, guiding teachers towards a critical and epistemologically based perspective, particularly starting with the analysis of their usual teaching and leading them to an epistemological reflection on the subjects ( to use a concrete theme and to discuss with them their epistemology), results in a substantial improvement of their teaching practices and, in particular, in their professional fulfillment.
We present and discuss some aspects of the teacher education program and the analysis made by participants during and after the participation in the designed program and the implications we point out for a new model of science teacher education using the curricular themes in an action-research perspective.
Vivemos num planeta onde os recursos naturais são escassos para a população que nele habita. Os nossos alunos são os adultos de amanhã e cabe-nos a nós uma boa parte da responsabilidade pela educação para o desenvolvimento sustentável. Planificamos, aplicámos e avaliámos uma sequência de ensino sobre a produção do papel a partir das suas matérias-primas. As atividades desenrolaram-se na interação entre a sala de aula e o ambiente não formal do Museu do Papel Terras de Santa Maria (Portugal).
Continuous technological advances keep challenging current and future engineers to anticipate and adapt to the new trends and paradigms that are expected to take place in a near future. One of such paradigms is the Industry 4.0 that encompasses the promise of a new industrial revolution based on the interconnectivity of people and systems to communicate, analyse and use information related to industrial processes. New challenges, as well as new opportunities, will rise in this digital landscape, demanding from future engineers the ability to adapt and grow in such ground-breaking environments. With such dynamic changes taking place in the current and future industries, engineering education has to adapt and prepare future graduates to work and function in these demanding environments. The set of skills envisaged to be held by future engineers is the ability to work and collaborate using digital means of participation as well as the ability to effectively use intercultural communicative skills. To this end, an exploratory study was conducted among different European Higher Education Engineering Schools to integrate a project with common aims and goals, resulting in various collaborative engineering activities that were designed to be carried out by undergraduate industrial and mechanical engineering students to further improve their learning outcomes and to acquire, or improve on, dedicated intercultural, communicative and colaborative skills. Following both quantitative and qualitative approaches, this study combined different types of data and methods of analysis in order to provide an exploratory account of the envisaged findings.

This paper deals with Single Carrier/Frequency Domain Equalization (SC/FDE) for uplink transmission within a Multi-User (MU) Multi-Input Multi-Output (MIMO) system where the number of Base Station (BS) antennas can be much larger than the number of transmitter antennas jointly using the same time/frequency resource at Mobile Terminals (MT). Selected Quadrature Amplitude Modulation (QAM) schemes are assumed for transmission, so that high bandwidth efficiencies are achievable. In this context, we consider either a linear detection or a reduced-complexity, iterative Decision Feedback (DF) detection, evaluate the achievable performances in both cases, and discuss them with the help of selected performance bounds and semi-analytically evaluated error floor levels. From our performance results, we conclude that simple linear detection techniques, designed to avoid the need of complex matrix inversions, can lead to unacceptably high error floor levels. However, by combining the use of such simple linear detectors with the appropriate interference cancellation procedure - within the iterative DF technique -, a close approximation to the Single-Input Multi-Output (SIMO) Matched-Filter Bound (MFB) can be achieved after a few iterations, even for 64-QAM schemes, when the number of BS antennas is five times higher than the number of antennas jointly used at the user terminals.
The aim of this study was to study the effects of a Senior Gymnastics Program (SGP), with duration of 12 weeks 2 times per week, on the functional capacity of the elderly in the municipality of Mação, through the application of the Senior Fitness Test (SFT). On the other hand, to perceive how Functional Capacity evolved in the elderly who did not benefit from the program. We tried to verify if an SGP, specific for this age group, caused significant effects in both genres in the improvement of the functional capacity of the institutionalized elderly. It was sought to evaluate the evolution of the functional capacity (FC) of the institutionalized elderly. who did not benefit from SGP. A quantitative, experimental, analytical and longitudinal research was carried out. The sample consisted of 2 groups of elderly institutionalized in the House of the Santa Casa da Misericórdia de Mação, one that we designated as experimental (GE) with 13 individuals (10 women and 3 men 87,15±6,09) who carried out the 12 week program and one that we denominated sedentary group (GS) with 10 (7 women and 3 men79,6 ±6,45 individuals who did not benefit from the program. As a conclusion, the experimental group showed statistically significant differences in all SFT battery tests, except for the 8 foot Up and Go again (p≥0.06).
Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now the rising concern within Europe. CWD will be outlined in this chapter gathering its epidemiology, transmission, diagnosis, genetics, and control. Prion diseases are fatal neurodegenerative diseases characterized by the accumulation of an abnormal isoform of the prion protein (PrPc), usually designated by PrPsc or prion. CWD is a prion disease of natural transmission affecting cervids detected mainly in North America. The first European case was detected in Norway, in 2016, in a wild reindeer; until April 2018, a total of 23 cases were described. The definite diagnosis is postmortem, performed in target areas of the brain and lymph nodes. Samples are first screened using a rapid test and, if positive, confirmed by immunohistochemistry and Western immunoblotting. It is not possible to establish a culling plan based on the genotype, once affected animals appear with all genotypes. However, some polymorphisms seem to result in longer incubation periods or confer a reduced risk. The control is not easy in captive cervids and even more in the wildlife; some recommendations have been proposed in order to understand the danger and impact of CWD on animal and public health.
The contribution of Special Education in the context of teacher education is becoming increasingly essential, especially if we take into account the epistemological wealth deriving from the relationship with numerous related sciences. This contribution aims at comparing the training axes of Italy and Portugal in order to detect common features and future research tracks in a comparative perspective and with an open look at complexity. In particular, the aim is to investigate whether (and how) the inclusive educational dimension of teachers is organized and designed to meet the needs of all pupils, also with reference to the programmatic actions promoted by the 2030 Agenda (ONU, 2015) which sees in the educational axis a real catalyst of development capable of breaking down inequalities and promoting lifelong learning opportunities for all. Without forgetting, then, that the teaching profession needs, today more than ever, a sharing, open on an international level, regarding the professional profile traceable in the main and priority competences to be possessed in the increasingly globalized knowledge society.
This paper describes a machine designed to process small PVC pieces, used in automobile cable testing equipment. This machine should allow several different processing tasks without too much reconfiguration, thus providing a high level of automation. The solution is based on a three axis movable platform moving inside a cage structure where several tools are attached. This paper describes the machine control hardware and software, not the mechanical structure.
The machine processes a piece at a time. The piece is placed in the platform and held in place by a gripper. The platform moves inside the cage placing the piece in the appropriate tool position, following a checklist of operations.
The machine is controlled by a PC (Personal Computer), equipped with a commercial I/O interface board and a motion control board. The software developed is composed of three modules for the different control and configuration needs. One used after the machine is physically reconfigured. The second module allows the definition of the operations to be performed and respective coordinates. This module is used when a new series of pieces is to be processed. The third module controls the manufacturing process.
Low-code development platforms are designed to accelerate software development with a minimum of hand coding. They have allowed professionals with distinct backgrounds to become software developers. This brings more professionals to IT areas, reskilling some of them from different areas of knowledge but, at the same time, it has also brought to the software development area many professionals without a strong background in this area. Although testing should be performed in all applications, regardless of the programming language or the platform used, this reinforces the need for testing low-code developed applications. In this work, we study the test automation process on the OutSystems low-code development platform. The focus is on Unit, Integration/API and System/End-to-End testing levels. Examples illustrate that the implementation of best practices during the development process can have a significant influence on the test automation process. However, it is important to know whether the workload associated with the implementation of the best practices can undermine the benefits of using a low-code platform and it is important to consider that not all test automation tools have the same behavior.
Consumers’ demand for functional fermented food that can fulfill nutritional needs and
help maintain a balanced diet while also having a positive impact on one’s health status is increasing
all over the world. Thus, healthy choices could include beverages with nutrients and bioactive
compounds which can be used as an effective disease-prevention strategy. Regular beer has certain
health benefits which inspire further research with the prospect of obtaining special functional beers
with little or no alcohol content. As observed, the special beer market remains highly dynamic and is
predicted to expand even further. Therefore, brewers need to keep up with the consumers’ interests
and needs while designing special beers, namely nonalcoholic beers (NABs), low-alcohol beers (LABs),
and craft beers (CBs). Thus, understanding the potential uses of bioactive compounds in special beer,
the wide range of therapeutic effects, and the possible mechanisms of action is essential for developing
healthier beverages. This review aimed to evaluate the nutritional features of special beers, and their
proven or potential beneficial actions on one’s health status and in preventing certain diseases.
An important scheduling function of manufacturing systems is controlled order release. While there exists a broad literature on order release, reported release procedures typically use simple sequencing rules and greedy heuristics to determine which jobs to select for release. While this is appealing due to its simplicity, its adequateness has recently been questioned. In response, this study uses an integer linear programming model to select orders for release to the shop floor. Using simulation, we show that optimisation has the potential to improve performance compared to ‘classical’ release based on pool sequencing rules. However, in order to also outperform more powerful pool sequencing rules, load balancing and timing must be considered at release. Existing optimisation-based release methods emphasise load balancing in periods when jobs are on time. In line with recent advances in Workload Control theory, we show that a better percentage tardy performance can be achieved by only emphasising load balancing when many jobs are urgent. However, counterintuitively, emphasising urgency in underload periods leads to higher mean tardiness. Compared to previous literature we further highlight that continuous optimisation-based release outperforms periodic optimisation-based release. This has important implications on how optimised-based release should be designed.
A pandemia do Covid 19 acelerou a digitalização na criação, produção, comunicação e consumo de moda. As normas de isolamento social e o fechamento de aeroportos impossibilitaram a realização de eventos de moda presenciais. Nesse contexto, marcas e estilistas buscaram soluções para lançarem suas coleções. Na Universidade do Estado de Santa Catarina a irrealizabilidade das actividades presenciais conduziu à realização do desfile de conclusão de curso de forma digital. Este artigo objetiva apresentar o relato de experiência da organização e realização do evento OCTA Fashion, demonstrando a divisão das tarefas em grupos de trabalho. Como resultado lançou-se em Dezembro de 2021 o fashion film composto de video conccito, desfile e documentário.
Background: Sedentary behavior has been considered an independent risk factor to health. The aim of this systematic review and meta-analysis was to examine associations between objectively measured sedentary time and physical fitness components in healthy adults. Methods: Four electronic databases (Web of Science, Scopus, Pubmed and Sport Discus) were searched (up to 20 September 2020) to retrieve studies on healthy adults which used observational, cohort and cross-sectional designs. Studies were included if sedentary time was measured objectively and examined associations with the health- or skill-related attributes of physical fitness (e.g., muscular strength, cardiorespiratory fitness, balance). After applying additional search criteria, 21 papers (11,101 participants) were selected from an initial pool of 5192 identified papers. Results: Significant negative associations were found between total sedentary time with cardiorespiratory fitness (r = -0.164, 95%CI: -0.240, -0.086, p < 0.001), muscular strength (r = -0.147, 95%CI: -0.266, -0.024, p = 0.020) and balance (r = -0.133, 95%CI: -0.255, -0.006, p = 0.040). Conclusions: The evidence found suggests that sedentary time can be associated with poor physical fitness in adults (i.e., muscular strength, cardiorespiratory fitness and balance), so strategies should be created to encourage behavioral changes.
Nowadays, groundwater vulnerability assessment has become a useful tool for groundwater contamination prevention. Groundwater vul-nerability maps provide useful data to protect groundwater resources and work as a tool for the improvement of changes in agricultural patterns and land use applications. The study area of this research survey is the Naturtejo UNESCO Global Geopark, located in central inland Portugal and corresponding to a mainly rural territory where intensive agricultural practices showed a rising tendency in the last decades. The most used method of vulnerability evaluation is the DRASTIC index. In this survey, a modified DRASTIC method, DRASTICAI, is introduced. A new attrib-ute designated as Anthropogenic Influence is introduced. Map algebra in a GIS environment allowed the computation of the two maps by overlaying the needed attributes. The Vila-Velha-de Rodão and Idanha-a-Nova mu-nicipalities show moderate to high vulnerability and, therefore, in need of monitoring, since intensive agricultural practices are the main economic activity. The algebraic subtraction of DRASTIC and DRASTICAI maps revealed a considerable increase in the risk of contamination, over the sur-veyed area, namely in Idanha-a-Nova where it is observed risk increase up to 45 points, changing from moderately vulnerable to highly vulnerable and, therefore, stressing the importance of anthropogenic activities.
One of the purposes of teachers is to ensure the motivation of the students in their classes and to maintain disciplined behaviours. However, the teaching styles and methodologies used do not always have a positive effect on student’s motivation and discipline. This study analysed the relationship between student’s perceptions of the controlling behaviours of their physical education teacher, together with amotivation and discipline styles from Self-Determination Theory. The sample comprised 922 students, aged between 14 and 18 years (M = 14.95; SD = 0.98). Students’ perceptions of less controlling discipline styles (control of the use of rewards) negatively predicted the thwarting of autonomy need. Conversely, a more controlling discipline style (judging and devaluing) positively predicted the thwarting of autonomy need, and this, positively predicted amotivation, which nega- tively predicted disciplinary behaviours and positively predicted undisciplined behaviours. Teachers must avoid using controlling behaviours like judging and devaluing, as this reinforces amotivation towards physical education and undisciplined student behaviours. The importance of designing classes where the student has responsibilities to make decisions and to be part of their own learning is pointed out.
Implementing best practices during the software development process can significantly influence the test automation process. This is true in all software applications, regardless of the platform or the programming language used, but it is even more important when the software is developed using low-code development platforms. These platforms are commonly used together with agile methodologies, and they are designed to accelerate software development with a minimum of hand-coding. Generally, when using these platforms and methodologies, the focus is on verbal and informal communication rather than documentation. The focus is on getting high-quality source code, adequate test sets, and greater interaction with the end customer. This highlights the need to use best practices in software development to achieve better quality software and facilitate the test automation process. In this work, we analyse the test automation on low-code development platforms and, more specifically, how the best practices for OutSystems development influence the test automation process. A survey on the opinion and practice of OutSystems platform professionals, 27 respondents, is also analysed and discussed. The goal is to understand how they recognise the influence that best development practices have on the testing automation process and how they apply these best practices in their daily activities.
Vehicular networks are emerging as a promising technology that enables reliable and low-cost solutions for intelligent transport systems (ITSs), mainly due to their enormous potential to be considered for multiple purposes and scenarios. These networks are characterized by unique and challenging features such as packet fragmentation, low node density, short contact duration, and network disruption. These features may result in the absence of a path between the source and destination nodes, which is one of the most challenging issues faced by this type of network. To overcome some of these problems, it is necessary to provide vehicular networks with sophisticated tools or methodologies to implement monitoring and management operations. However, designing efficient solutions for this type of network is not an easy task due to its particular characteristics. This paper elaborates on a comprehensive survey focusing on promising proposals to deal with monitoring and management functionalities in vehicular networks. This work aims not only to present the state of the art on monitoring and management solutions but also to analyze their benefits and drawbacks, identify open issues, and provide guidelines for further contributions.
The concept of Precision Agriculture is usually associated with the usage of high-end technology equipment (hardware or software) to evaluate or monitor the conditions of a determined portion of land, adjusting afterwards the production factors, like seeds, fertilizers, pesticides, growing regulators, water, according to differential detected characteristics. This paper describes an algorithm developed to analyze and process images to recognize fruits, particularly peaches, and calculate it dimensions, like volume and weight. The recognition of peaches on their natural conditions on trees depends on several spatial- and time-variable parameters and requires complex segmentation algorithms. The proposed algorithm applies image segmentation for extraction of characteristics such as color and shape. These characteristics were used to train a classification method through a Support Vector Machine (SVM) to improve the recognition rate of fruits. The algorithm is designed to acquire images with a high-resolution camera installed in a drone that will fly between the tree lines. The production prediction of 29.3 tons per hectare was obtained based on volume and relation weight/volume calculated for the recognized peaches. An overall precision of 72% was achieved for the prediction rate of peaches in orchards (808 trees/ha). This is the first study regarding the application of these concepts under orchard trees aiming the production prediction along the fruit maturation. Other useful future applications are foreseen in orchard trees, related not only to production prediction, for this type of algorithm.

Based on the concepts of Delay-Tolerant Network (DTN) and Opportunistic Networks, Vehicular opportunistic networks have been proposed to interconnect developing communities, or to implement disaster recovery networks when all other networks fail. Other possible application scenarios for these networks include traffic monitoring, accident warnings, advertisements, and information retrieval applications. The diversity of these network environments introduces challenging issues related to the architecture, protocol designs, interoperability, security, management, and stability of vehicular opportunistic networks. Furthermore, these networks are characterized by variable and intermittent connectivity and frequent network partition. The store-carry-and forward strategy can be used to cope with disconnections. However, in sparse networks with low node density, this strategy may be complemented with the introduction of stationary relay nodes into the network. These nodes are placed along vehicle's routes and create additional transmission opportunities. Therefore, when correctly positioned they will contribute to augment the message delivery ratio. This chapter investigates recent advances related to the deployment of stationary relay nodes on vehicular opportunistic networks. Furthermore, it presents a study that evaluates the impact of adding stationary relay nodes on the performance of DTN routing protocols applied to vehicular opportunistic networks. Two distinct environments were considered, rural and urban scenarios. Each of them combines different application scenarios, map areas, node density, and vehicle movement models. For both scenarios, results show that stationary relay nodes increase the number of contacts between network nodes, improving the overall performance of the network in terms of message delivery ratio.

The agro-industrial system represents annually circa 3,6 x 109 € in the formation of the Centro
Region of Portugal gross income and that accounts for 39% of the Portuguese overall return for
this sector. Given this dynamics it is of utmost importance to perform a consistent strategy to
promote the sustainable growth of this regional system income.
Therefore, the CERNAS/IPC research unit has developed an integrated approach bringing
together several regional actors under a networking logic that links the industrial needs with the
academia R&D capabilities, and of capacity building and entrepreneurship (2011-2013).
This strategy is rooted in the InovCluster, where CERNAS leads two anchor projects, the
in_AGRI and the ECODEEP, and collaborates with a third one, the AGRITRAINING. The
in_AGRI aims the upgrade of the system value chains by bridging the academia with the
industry in a series of workshops, supported with a knowledge transfer platform and a network
of research facilities, and ECODEEP will develop eco-efficiency tools, based on a LCA
approach to enhance the overall sustainability by improving practises and find new solutions
within an industrial ecology framework. The AGRITRAINING surveys the training needs of the
system, looking forward to complement the actual capacity building achieved by the Master
courses in Food Engineering and Environmental Management. In addition, an advanced training
in Environmental Entrepreneurship is being implemented, and an Innovation Management for
SME’s program is being designed, promoting a cultural change towards the sustainable welfare
of our present and future generations.
Portugal, located in the Mediterranean region, one of the "Hot Spot" of the planet, has a huge variability in terms of topography, soils, climate, agriculture, traditions, resulting in a high diversity of animal genetic resources, represented by 15 native cattle breeds, most of them threatened. A significant percentage of extensive beef cattle production in Portugal is based on the use of animals, differing from north to south region, with good maternal aptitude, hardiness, a low growth performance and exceptional adaptation to the environment where they live, and especially to the local feed, naturally produced. In the north of the country and the Azores, dairy breeds predominate, while in the south beef breeds are most prevalent. Portugal is not self-sufficient in beef production, however it is possible to appreciate an market for beef produced by indigenous breeds from extensive and organic production systems. Beef from indigenous breeds is considered to be a high quality product, mainly because of the superior taste and structure of the meat resulting from the production system: slow growth rate and type of vegetation consumed. This product differentiation has allowed the enlargement of small niche markets and has led to an increase in the value of meat with a Protected Designation of Origin (PDO) or with organic beef. Since portuguese agriculture cannot compete on quantity or production cost with other competitors, differentiation and quality seem to be the alternatives that may stimulate rural activities in Less Favoured Areas (LFAs) and create a regional added value able to contribute to sustainable development. Extensive animal production systems can be an important component of environmental and landscape protection, as well as contribute to the decrease of the human, physical desertification of our rural areas and animal genetic resources.

ABSTRACT: The vampire has become a fascinating character whose
distribution and consumption have been reinvigorated over the past two
decades thanks to series and sagas such as Buffy the Vampire
Slayer, Twilight and True Blood. Conceived from the same myth, these
three cross-platiorm products develop transmedia narratives in which
well-designed storyworlds, distributed across digital and analogue
channels, allow the engagement of the viewer, user and player. This
chapter proposes a case study of Vampire: The Masquerade as a
transmedia narrative. A product that combines a tabletop role-playing
game (RPG), live-action role-playing game (LARP), card game, television
series and two computer games. The chapter aims to highlight the role of
the narrative world as narrative engine. The chapter provides reflections
on how the cross-platiorm distribution of storyworlds, characterised by
performative aspects, can foster audience participation and exploit the
commercial success of a product.
The Genetics and Biotechnology Conference (JGB) of the University of Tras-os-Montes
and Alto Douro (UTAD) is an annual scientific event organized jointly by the Nucleus of
Students of Genetics and Biotechnology (ADNGB) of UTAD and the Direction of the
Course of Genetics and Biotechnology in collaboration with the teaching staff of the
Department of Genetics and Biotechnology (DGB). As a result of the scientificpedagogical partnership established between professors of DGB (UTAD) and of Faculty
of Biological and Environmental Sciences of the University of León (UL), Spain, it was
considered important to repeat the shared organization of this event between
professors and students of the UTAD and UL designating it as XII Genetics and
Biotechnology Conference / II Genetics and Biotechnology Iberian Conference (XII JGB /
II JIGB). The main objective of the XII JGB /II JIGB is to update knowledge in the area of
Genetics and Biotechnology. To this end, the focus of this event is the conferences given
by renowned national and international scientists and the thematic workshops that will
constitute more practical sessions. The XII JGB /II JIGB will also focus on interaction,
exchange of experiences and scientific debates between Portuguese and Spanish
students and professors. The best oral and posters presentations will be awarded. The
target audience is Portuguese and Spanish students, researchers and university
professors from the scientific areas of Biological Sciences and Biotechnology as well as
High School teachers from the Biology area. A wide variety of topics will be discussed, in
the different areas of Genetics and Biotechnology, such as Plant, Animal, Human,
Microbial, Evolutionary, Cancer, Forensic, Ethics, Entrepreneurship, among others.

A metodologia a utilizar no desenvolvimento deste trabalho irá incidir na Metodologia Não Intervencionista de base qualitativa, e Metodologia Mista Intervencionista.
Como objetivo principal, este trabalho visa aprofundar a viabilidade da introdução destes materiais no setor da moda de autor, e verificar se estes mostram ser uma opção viável.
The continuous rise in the world’s population has increased the need for food, resulting in a rise of agricultural holdings to ensure the supply of these goods directly to the populations and indirectly to all processing industries in the food business. This situation has led agriculture to reinvent itself and introduce new technics and tools to ensure tighter control of the crops and increase yields in food production. However, the lack of labor coupled with the evolution of weeds resistant to herbicides created a crisis in agricultural food production. However, with the growing evolution in electronics, automation, and robotics, new paths are emerging to solve these problems. A robotic rover was designed to optimize the tasks of weed control and collection of fallen fruits of an orchard. In weed control, a localized spraying system is proposed, therefore reducing the amount of applied herbicides. With fruit collection, it is possible to direct fallen fruits for animal feeding and possible to reduce microbial activity on the next campaign crops, therefore avoiding damage. This study proposes the simulation of this robotic rover on robotic simulation software. It also proposes the replication of a similar environment of an orchard to generate an algorithm that controls the rover on the tasks of localized spraying and fallen fruit collection. Creating and testing these algorithms by using a robotic simulator speed up and ease the evaluation of different scenarios and hypotheses, with the added benefit of being able to test two tasks simultaneously. This method also allows greater freedom and creativity because there are no concerns about hardware damage. It should also be noted that development costs are very low.
In line with the context of Industry 4.0, forestry, and in particular the entire ecosystem around it, also needs digitalization solutions in order to allow better interaction between all agents that work and live from the forest. It is important for a better management of forest resources allowing productivity gains, more sustainability and resilience. One of the agents that can benefit, but also contribute to better forestry, are machine producers.With digitalization, the machinery is now equipped with new and better sensors that can
be used not only for machine operations but also for forest management, through LiDAR (Light Detection
And Ranging) or RGB (Red, Green, Blue) cameras for example. On the other hand, there are new needs
for predictive maintenance or solutions for remote assistance of machines operating in the forest, typically
in isolated areas with great limitations in access to communications. Thinking about these technological
challenges, this work seeks to provide answers with communication solutions in forest machines, enabling
the digitalization of functionalities, also allowing remote access to machine controllers in order to provide
them with connectivity in an IIoT (Industrial Internet of Things) scenarios. New hardware modules designed
in partnership and according to the prerequisites of a forest machine manufacturer are presented. These
modules are a step towards digitizing the machines and opening up the scalability of new requirements,
as well as remote access through additional gateways. The results already obtained in real scenarios show
that these modules can be a concrete solution for the current and emerging needs of industrial machine
manufacturers.
Climacteric fruit such as peaches are stored in cold chambers after harvest and usually are maintained there until the desired ripening is reached to direct these fruit to market. Producers, food industries and or traders have difficulties in defining the period when fruit are at the highest level of quality desired by consumers in terms of the physical-chemical parameters (hardness –H–, soluble solids content –SSC–, and acidity –Ac–). The evolution of peach quality in terms of these parameters depends directly on storage temperature –T– and relative humidity –RH–, as well on the storage duration –t–. This paper describes an Artificial Intelligence (AI) Decision Support System (DSS) designed to predict the evolution of the quality of peaches, namely the storage time required before commercialization as well as the late commercialization time. The peaches quality is stated in terms of the values of SSC, H and Ac that consumers most like for the storage T and RH. An Artificial neuronal network (ANN) is proposed to provide this prediction. The training and validation of the ANN were conducted with experimental data acquired in three different farmers’ cold storage facilities. A user interface was developed to provide an expedited and simple prediction of the marketable time of peaches, considering the storage temperature, relative humidity, and initial physical and chemical parameters. This AI DSS may help the vegetable sector (logistics and retailers), especially smaller neighborhood grocery stores, define the marketable period of fruit. It will contribute with advantages and benefits for all parties—producers, traders, retailers, and consumers—by being able to provide fruit at the highest quality and reducing waste in the process. In this sense, the ANN DSS proposed in this study contributes to new AI-based solutions for smart cities.
Strawberry tree (Ericaceae) is a species of Mediterranean climates growing in several
countries of the Mediterranean basin as well as in Portugal and Ireland. The edible fruits have
been used in different ways yet the production of a popular spirit is still the main application.
The species is also interesting from an ecological perspective since it is drought tolerant and
fire resistant. In spite of its large distribution in Portugal little is known about the genetic
diversity of the species and no efforts have been carried out to select the most interesting
trees. Material from selected trees (based on fruit production) in a total of 27 was collected all
around the country covering the distribution area of the species. In order to find out DNA
markers to characterise genetic diversity and to fingerprint Arbutus unedo, random amplified
polymorphic DNA (RAPD) and microsatellite markers (SSR) were used.
The set of 20 RAPD primers used generated 124 bands, from which 71 (57.3%) were
polymorphic and the expected heterozygosity was 0.27±0.014. The cluster analysis
(UPGMA) based on the Jaccard similarity index showed a similarity of 71% among the trees
of different origins. Only four genotypes could be grouped according to their geographical
distribution.
Eleven SSR primers designed for Vaccinium (an Ericaceae as A. unedo) were selected
according to their polymorphism, number of alleles per locus, cross-amplification, allele
scoring quality and the repeat motif, and were tested in A. unedo. Six loci showed to be
polymorphic, with 71% mean expected diversity, 10.5 mean number of alleles, and 67% of
average polymorphic information content. A mean homozygote excess was found (11%)
although not significant. Estimation of null allele frequency was about 9% on average. The
linkage disequilibrium test showed that all the loci were independent. The UPGMA
clustering based on the Lynch and Ritland coefficient showed that only two genotypes shared
about 50% of the alleles, but without a consistent geographic pattern, similarly to the results
obtained by RAPD analysis. The Mantel test confirmed that there is no correlation between
the genetic and the geographical distance matrices, for both makers. Reduced gene flow, due
to fragmentary distribution, together with the type of mating system of this species
(pollination by small insects), are plausible explanations for these results. As far as we know
our work is the first detailed study to evaluate A. unedo diversity by molecular markers
opening new perspectives for fingerprinting analysis and for conservation and improvement
purposes.
After the accidents occurred during the first decade of this millennium, such as the World Trade Center (2001), London (2005) and Madrid (2004), special attention was given to the study of robust structures subjected to different accidental loads. The World Trade Center attack highlighted troublesome weakness in connections, which exhibited poor performance caused by brittle failure. Structural details played a very significant behavioural role when the structure is subjected to impulsive loads [1].
Concerning the behaviour of steel joint, the literature presents several studies on steel connections under both static and cyclic loads [2, 3]; many results of these studies have contributed for improving the current standards, such as the Eurocode 3, part 1-8 [4]. However, only scarce information exists concerning the behaviour of these joints directly loaded by higher loading rates [5].
This paper is devoted to the report of an experimental programme on steel joints under impact loading, in particular to the assessment of T-stub response under tension. The T-stub is used to evaluate the behaviour of the tensile components that are responsible for the deformability of the joint, such as the end plate in bending. Firstly, the paper describes the features of an experimental system developed at the University of Coimbra, to apply high rates of loading; then, it presents the experimental campaign and the corresponding results.
The test apparatus is defined by a rigid reaction frame fixed to a reaction slab and connected to a rigid “flying beam” (HEM 340, S355J2); the impact force is applied in this beam through a pneumatic driven cylinder ( = 125 mm). This “flying beam” consists in a second class lever pivot located at the opposite end of the cylinder location, and the tested specimen is subjected to the dynamic force at the middle of this beam. The pneumatic cylinder was designed to work with a maximum operating pressure of 30 MPa. During the impact tests, force, displacements, accelerations and strains are measured. Because this type of tests occurs in a very short time intervals (hundredths of a second), specific equipment with large sample rate are used.
The experimental programme includes two impact tests on welded T-stubs: i) test T-10-D120-160 - rapidly applied loading of 120 Bar [12 MPa], followed by 160 Bar [16 MPa]; and ii) test T-10-D160 - rapidly applied loading of a single impact equal to 160 Bar [16 MPa]. The results of these tests are compared against reference quasi-static tests [6]. The T-stub geometry is defined by two plates, the flange and the web, both with 10 mm of thickness and welded by means of a continuous 45º fillet.
The flange is bolted through two bolts M20, grade 8.8 fully threaded.

Com o objetivo de avaliar a possibilidade de utilização da melancia (Citrullus lanatus) na alimentação de ruminantes caracterizou-se o fruto do ponto de vista nutricional e formulou-se um regime alimentar para ovelhas em lactação. A melancia apresenta elevados teores em PB (14,47%MS ±4,54) e NFC (53,80%MS ±8,89) e baixos teores em MS (3,80% ±1,62), NDF (20,63%MS ±2,80) e ADF (18,39%MS ±2,93). Utilizando a técnica do Quadrado de Pearson, acertámos uma mistura para 45,01%MS constituída por 54,3% melancia + 45,7% feno de aveia. As necessidades diárias de uma ovelha com 70kg de peso vivo a produzir 1,3 kg de leite por dia com 7% de gordura são as seguintes: EM 19,07MJ/dia; PB 183,6g/dia; RDP 148,6g/dia; UDP 35,0g/dia; EE≤98,0g/dia; NDF≥784,0g/dia; NFC≤705,6g/dia; CIMS 1,96kg/dia. Utilizando a mistura como alimento base mais 100g de alimento composto distribuído na ordenha, elaborou-se um regime alimentar (1,8694kgMS/dia de mistura e 0,0906kgMS/dia de alimento composto) que satisfaz as necessidades em EM 19,48MJ/dia, PB 229,47g/dia, RDP 150,62g/dia, UDP 78,85g/dia, EE 46,99g/dia, NDF 791,04g/dia e NFC 752,03g/dia sem ultrapassar a CIMS. Conclui-se que a melancia pode ser utilizada na alimentação de ovelhas quando misturada com feno de aveia. É uma solução alimentar interessante em setembro/outubro quando há carência de pastagem.
O processo Europeu de Convergência do Ensino Superior, determinado pelo processo de Bolonha, coloca o aluno no centro do processo de ensino-aprendizagem, focando os seus estudos nas competências que deve ter o recém-formado e potenciando a iniciativa e a aprendizagem autónoma do aluno. Essa mudança de paradigma educacional está ligada a uma mudança metodológica que reforça o papel ativo e o pensamento crítico do aluno.
Para adquirir as competências o aluno deve usar o seu ou os seus estilos de aprendizagem predominantes que têm um caráter de predisposição para aprender de determinada forma.
Neste sentido, no processo de ensino/aprendizagem, a análise dos estilos de aprendizagem assume um papel fundamental para saber como aprendem os alunos.
Este estudo foi desenhado para avaliar os estilos de aprendizagem dos alunos das seis escolas de ensino superior do Instituto Politécnico de Castelo Branco. É parte de uma tese de doutoramento em Estatística Multivariante Aplicada desenvolvida na Universidade de Salamanca (Silveira, P., Villardón, MP, Galindo, MP, 2013).
Pretende-se, também, evidenciar o papel dos métodos fatoriais multivariantes na análise de dados que envolvem estruturas complexas de Covariação/Interação, com particular destaque para os métodos Biplot que nunca foram utilizados neste contexto.
Para recolher a informação foi utilizado o questionário CHAEA (Questionário Honey-Alonso de Estilos de Aprendizagem criado por Alonso e Honey em 1995).
Assente no pressuposto do valor da interação da escola com o meio local, concretizado em visitas de estudo projetadas para propiciarem aprendizagens curriculares, desenvolvemos uma estratégia formativa potenciadora da oportunidade de as nossas estagiárias se iniciarem no ensino das ciências e da matemática no 1.0 Ciclo do Ensino Básico (1.0 CEB) explorando a interação entre contextos formais e não-formais, através de estudos de Investigação-ação (1-A), desenvolvidos durante o estágio. O estudo aqui apresentado teve como objetivo analisar a perspetiva de futuras professoras sobre o valor atribuído á interação entre os dois contextos na sua formação. Em termos metodológicos, optámos pela análise documental de catorze relatórios de estágio do Mestrado em Educação Pré-escolar e Ensino do 1.° CEB, com especial enfoque nas reflexões das futuras professoras sobre o recurso aos contextos
não-formais nas práticas de ensino.
Os resultados permitem concluir que vários espaços da cidade têm vindo a evidenciar um elevado potencial motivacional, de desenvolvimento profissional e de inovação pedagógica e didática dos futuros professores
O presente relatório reflete a prática de ensino desenvolvida no estágio realizado no âmbito da unidade curricular de Prática de Ensino Supervisionada, bem como o
trabalho de investigação desenvolvido no âmbito da unidade curricular de Projeto do
Ensino Artístico, sendo dividido em duas secções.
A primeira secção aborda a Prática de Ensino Supervisionada onde se faz a
apresentação da escola e dos alunos, se exibe o plano de estágio, planificações e
relatórios de aula, concluindo-se com uma reflexão crítica do trabalho desenvolvido ao
longo do estágio. Na segunda secção, é exposto o trabalho de investigação desenvolvido
sob o tema “O software educativo SmartMusic no ensino da Flauta Transversal”.
Actualmente, são escassas as actividades que o Homem realiza sem o recurso às
tecnologias, sendo que a Música não é excepção. A tecnologia está intrincadamente
associada à Música, quer na evolução dos instrumentos tradicionais e invenção de
instrumentos eletrónicos, no surgimento de softwares de gravação e reprodução
sonora, quer em softwares educativos. Os softwares educativos têm por objectivo
auxiliar a aprendizagem dos alunos e, de entre muitos, destaca-se o software
SmartMusic.
Com a finalidade de avaliar a utilidade e potencialidades educativas do software
SmartMusic como ferramenta no ensino da flauta transversal, realizaram-se sessões de
apresentação e exploração do software, onde professores e alunos de flauta transversal
tomaram conhecimento e experimentaram o mesmo, seguidas de entrevistas para a
recolha de dados.
Este Relatório de Estágio está dividido em duas partes, refletindo o trabalho desenvolvido no âmbito do Mestrado em Ensino de Música, lecionado na Escola Superior de Artes Aplicadas do Instituto Politécnico de Castelo Branco.
O objetivo da primeira secção é descrever o estágio pedagógico, no contexto da unidade curricular Prática de Ensino Supervisionada. Este estágio decorreu no ano letivo de 2019/2020, no Conservatório de Música da Jobra.
A segunda secção do Relatório está dividida em duas partes. A primeira, descreve a evolução da inteligência emocional, aprofundando o estudo desse conceito em vários autores. A segunda parte incide sobre um estudo de cariz experimental acerca da forma como a inteligência emocional é capaz de influenciar a performance de um trompista. O conceito de inteligência emocional irá englobar aspetos como a motivação e o otimismo no aluno, bem como quais serão as emoções não reguláveis durante um momento de performance que o influenciam diretamente. O estudo incidirá também sobre a análise do teste de inteligência emocional designado Trait Meta-Mood Scale – 24, criado para quantificar a inteligência emocional. No final é possível compreender que a inteligência emocional tem sim um papel muito importante na performance, bem como na forma em que isso é observável.
Durante a segunda metade do século XIX, foi
constituída uma coleção de escultura italiana
no Palácio Nacional da Ajuda. Neste âmbito
foi estudada esta coleção num contexto de
investigação alargada a todo o núcleo escultó-
-rico. Contudo, e tendo em referência o ponto
de partida geral, encontrou-se um escultor
italiano nascido em 1833 e proveniente de
Modena, que veio trabalhar para Portugal,
a convite do rei D. Luís I. Neste âmbito, e a
propósi-to da sua vinda, procedemos à investigação da sua produção artística, no campo da
escultura em mármore de Carrara. Colocou-se
então a questão des-te convite e qual a hipótese
de desenvolvimento da sua obra escultórica
num ambiente da segunda metade do século
XIX, em Portugal e neste perío-do histórico.
O objetivo foi investigar a permanência de um
artista italiano na cidade de Lisboa a convite

Cistus ladanifer L. (Cistaceae) is an endemic and abundant resource in the Iberian
Peninsula and North Africa. This plant exudes an aromatic resin nowadays valued in the
perfumery and fragrance industry. Traditional processes for the extraction and isolation
of such resin use boiling water or alkaline water followed by acidic precipitation.
However, a concern arises about the effluents resulting from these extraction processes.
To overcome this concern, labdanum resin was extracted with Na2CO3 solution (25 g/L)
at 60 oC and precipitated with sulphuric acid (5 M). The residual water was evaluated
regarding total phenolic content, suspended solids, electric conductivity, and sulphate,
sodium, magnesium, and calcium content. The effluent was characterized by a total
phenolic content of 1245 ± 455 mgGAeq/L, 1338 ± 101 mg/L of suspended solids, pH of
approximately 2, electric conductivity of 34.8 ± 0.7 mS/cm, 22284 ± 710 mg/L of
sulphate, 9696 ± 1072 mg/L of sodium, 3.97 ± 0.24 mg/L of magnesium, 3.52 ± 0.80
mg/L of calcium, and a Sodium Adsorption Ratio of 876 ± 112. Because the values were
far from the limit values set by Portugal decree-law 236/98 for residual waters discharged
and irrigation waters, it was concluded that efforts should be made to optimize the
extraction process. In that regard, a factorial designed experiment was done to evaluate
the effect of Na2CO3 concentration (0; 2.5; and 25 g/L), extraction temperature (60 and
100 oC) and acidification extent (pH 2, neutralization, and no acidification) on the residual
water quality and on the yield of labdanum resin extraction. Alkalinization and
acidification are important to obtain high resin extraction yields (Andalusian vs.
Zamorean process), but mostly alkalinization may be reduced to meet sulphate criteria
for discharge without significantly affecting resin extraction yields. Despite that, to meet
salinity criteria for irrigation waters a higher reduction in alkalinization is needed for
Andalusian processes. Phenolic content, although lower for extractions done at 60 oC,
was far from the limit values for discharge, regardless experimental conditions. Given the
high phenolic content the residual water from labdanum extraction by both traditional
processes must be treated before discharge. If separated, phenolic compounds may be
valorized as a by-product.
O objetivo central desta dissertação é o estudo e desenvolvimento de algoritmos e
interfaces mediados por computador para performance e criação musical. É sobretudo
centrado em acompanhamentos em Jazz clássico e explora um meta-controlo dos parâmetros
musicais como forma de potenciar a experiência de tocar Jazz por músicos e
não-músicos, quer individual quer coletivamente.
Pretende contribuir para a pesquisa existente nas áreas de geração automática de
música e de interfaces para expressão musical, apresentando um conjunto de algoritmos
e interfaces de controlo especialmente criados para esta dissertação. Estes algoritmos
e interfaces implementam processos inteligentes e musicalmente informados,
para gerar eventos musicais sofisticados e corretos musical estilisticamente, de forma
automática, a partir de um input simplificado e intuitivo do utilizador, e de forma coerente
gerir a experiência de grupo, estabelecendo um controlo integrado sobre os parâmetros
globais.
A partir destes algoritmos são apresentadas propostas para diferentes aplicações
dos conceitos e técnicas, de forma a ilustrar os benefícios e potencial da utilização de
um meta-controlo como extensão dos paradigmas existentes para aplicações musicais,
assim como potenciar a criação de novos. Estas aplicações abordam principalmente
três áreas onde a música mediada por computador pode trazer grandes benefícios,
nomeadamente a performance, a criação e a educação.
Uma aplicação, PocketBand, implementada no ambiente de programação Max,
permite a um grupo de utilizadores tocarem em grupo como uma banda de jazz, quer
sejam ou não treinados musicalmente, cada um utilizando um teclado de computador ou um dispositivo iOS multitoque. O segundo protótipo visa a utilização em contextos
coletivos e participativos. Trata-se de uma instalação para vários utilizadores, para ecrã
multitoque, intitulada MyJazzBand, que permite até quatro utilizadores tocarem juntos
como membros de uma banda de jazz virtual.
Ambas as aplicações permitem que os utilizadores experienciem e participem de
forma eficaz como músicos de jazz, quer sejam ou não músicos profissionais. As aplicações
podem ser utilizadas para fins educativos, seja como um sistema de acompanhamento
automático em tempo real para qualquer instrumentista ou cantor, seja como
uma fonte de informação para procedimentos harmónicos, ou como uma ferramenta
prática para criar esboços ou conteúdos para aulas.
Irei também demonstrar que esta abordagem reflete uma tendência crescente entre
as empresas de software musical comercial, que já começaram a explorar a mediação
por computador e algoritmos musicais inteligentes.

No meio sociocultural ocidental actual, vive-se num ambiente de características multiculturais, nomeadamente no campo musical. Neste campo em específico, verifica-se um amplo leque de artefactos, articulações sonoras e linguagens musicais que não fazem parte estrutural da nossa cultura musical “histórica” e “curricularizada”, que predomina na abordagem das instituições de educação musical e de educação musical especializada.
Ora, daqui podemos deduzir que há um claro défice da presença de outras culturas musicais nos conteúdos dos currículos actuais. Com base nesta premissa surge este trabalho - por considerar que a presença destas diferentes culturas no âmbito do nosso ensino musical ocidental representa um factor essencial para que os alunos construam uma base sólida de compreensão em relação à origem e significado dos processos dinâmicos, práticas e linguagens musicais que constituem o seu ambiente musical contemporâneo. Deste modo, estes poderão atingir um equilíbrio satisfatório no desenvolvimento da sua musicalidade e poderão atingir um conjunto de competências relevantes e uma integração muito mais completa e criativa no contexto musical e artístico actual.
A procura pela integração sólida destes conceitos na Educação Musical num sentido amplo, obriga-nos a reflectir sobre possíveis Denominadores Comuns presentes nas várias culturas, sobre os quais poderá incidir o foco que levará ao desenvolvimento de uma metodologia de ensino adequada às condições do meio musical actual.
Posto isto, este trabalho constitui um esboço metodológico para a disciplina de Música de Conjunto assente na premissa de uma sociedade multicultural, aplicando o conceito dos universais na música - os Denominadores Comuns.

As TIC podem ser consideradas como impulsionadoras de novas estratégias no que concerne ao processo de ensino/aprendizagem. O Portal Educativo, entendido como um recurso digital concebido para ser utilizado em contexto educativo, apresenta um conjunto de caraterísticas que tem como principal objetivo, promover e facilitar a aquisição e compreensão de novos conhecimentos. Através da integração de diferentes formas de representação de vários conteúdos, pela introdução de ajudas visuais e sonoras, vem
criar a possibilidade dos alunos poderem vir a ter índices mais elevados de motivação e interesse na realização de atividades.
A investigação pretendeu verificar se a utilização do Portal Educativo ≪Escolovar≫ poderia contribuir na melhoria do processo de ensino/aprendizagem no 1o CEB, ao nível da
matemática, numa turma de 4º ano com 18 alunos, em contexto da Pratica de Ensino Supervisionado. A investigação foi de carater qualitativo, tendo sido realizadas observações participantes, notas de campo e aplicação de questionários aos alunos. Foram também realizadas entrevistas semiestruturadas aos professores do 1o CEB do Agrupamento com a finalidade de se realizar uma triangulação de dados a fim de se procurarem comparar as opiniões entre os alunos e os professores. Com a analise dos dados, foi possível verificar que os alunos já possuíam algumas competências digitais que lhes permitiram utilizar o computador e que a utilização do Portal Educativo e um importante recurso didático no processo de ensino/aprendizagem, dado que os resultados vieram comprovar um maior envolvimento dos alunos nas atividades propostas e uma maior facilidade na aquisição de conhecimentos, em particular, na medição de ângulos. Por outro lado, a presença de um contexto multimédia associado a um contexto lúdico, foram determinantes para que os objetivos de aprendizagem fossem mais facilmente atingidos, devido a uma maior motivação e envolvimento dos alunos.
O presente Relatório Final do Mestrado em Ensino de Música realizado na Escola Superior de Artes Aplicadas do Instituto Politécnico de Castelo Branco (ESART-IPCB) é constituído por duas partes distintas.
A primeira parte, denominada de Prática de Ensino Supervisionada, apresenta, descreve e reflete o trabalho desenvolvido ao longo do estágio de prática de ensino realizado na Academia de Música e Dança do Fundão [AMDF], orientado e supervisionado, respetivamente, pelo Professor Carlos Branco e pelo Professor Doutor Adriano Aguiar. Nesta parte, é feita a caracterização da escola e do meio onde esta está situada, a cidade do Fundão, apresenta-se a caracterização dos alunos envolvidos no nosso estágio, bem como a descrição das atividades realizadas com os mesmos durante as aulas de instrumento e as aulas de classe de conjunto.
A segunda parte, denominada “Linhas de Orientação para uma Abordagem Pedagógica ao Contrabaixo Barroco”, reúne um conjunto de informações orientadoras para a iniciação do estudo e interpretação do instrumento Contrabaixo no âmbito da Música Antiga. Engloba o contexto da interpretação dos reportórios dos séculos XVI, XVII e XVIII, as características da sua linguagem e os alicerces que permitem uma aproximação a uma abordagem pedagógica com características históricas. Sendo direcionado para o Contrabaixo, o trabalho foca a principal linha de interpretação deste instrumento versando a conceptualização da realização de um baixo contínuo. Tenta, igualmente, explanar a origem da designação do instrumento bem como as características dos materiais para a sua prática musical.
O projeto PerSoParAge - Recursos pessoais e sociais para a autonomia e participação social numa sociedade envelhecida, tem o objetivo de desenvolver propostas e ferramentas de análise e intervenção que respondam aos desafios das regiões envelhecidas do interior de Portugal, partindo de uma avaliação do território, nos distritos de Castelo Branco, Guarda e Portalegre. O consórcio que representa o projeto é formado pelo Instituto Politécnico de Castelo Branco, Instituto Politécnico de Portalegre, Instituto Politécnico da Guarda, Instituto Politécnico de Bragança, Câmara Municipal de Castelo Branco e Câmara Municipal de Idanha-a-Nova. O projeto pretende conhecer os processos e os perfis de envelhecimento das comunidades do interior através da avaliação multidimensional com vista a definir o seu perfil social, funcional e dos recursos disponíveis, assim como identificar as necessidades das organizações destas comunidades. Esta comunicação apresenta os dados da componente de avaliação do conhecimento, utilização e potencial das Tecnologias de Informação e Comunicação pelas pessoas mais velhas das regiões estudadas. A metodologia utilizada foi de natureza predominantemente quantitativa, com recursos à aplicação de dois inquéritos por questionário, um destinado aos indivíduos dos 50 aos 64 anos e o outro à população com 65 ou mais anos. Este instrumento foi especificamente elaborado para o efeito, validado por especialistas, contendo questões de resposta fechada e aberta. A análise e discussão dos resultados permitirão a construção de conhecimento que responda aos desafios das alterações demográficas sentidas nas regiões abrangidas e o desenvolvimento de estratégias de intervenção e políticas territoriais de envelhecimento, nomeadamente soluções que promovam a utilização das tecnologias digitais e assistivas, no sentido de melhorar a qualidade de vida dos idosos e de promover a sua integração, participação e implicação no desenvolvimento dos territórios.
A marca é um sinal distintivo que identifica produtos e serviços no mercado e o seu registro garante a exclusividade de uso desse sinal pelo titular do direito no território ou país onde o re-gistro for concedido. Ela é uma modalidade de propriedade industrial, como são as patentes, as indicações geográficas e os desenhos indus-triais. Segundo Lei da Propriedade Industrial brasileira, a 9279/1996 (LPI), por meio do disposto no seu artigo 122, “são suscetíveis de registro como marca os sinais distintivos visualmente perceptíveis, não compreendidos nas proibições legais” (BRASIL, 1996). Para que o registro da marca seja concedido e a exclusividade de uso esteja assegurada ao seu requerente, é necessário que passe pelo exame realizado no Instituto Nacional da Pro-priedade Industrial – INPI. No exame, vários critérios de registrabilidade são verificados, no entanto, o que interessa a este trabalho é o requisito da distintividade O objetivo deste trabalho é o de apresentar uma tipificação das marcas depositadas no INPI/Brasil, de acordo com os seus graus de distintividade e com as características do mer-cado onde se inserem. A premissa foi a de que a força comunicativa das marcas encontra-se na sua distintividade, especialmente, no que se refere ao estabelecido pelo inciso VI do artigo 124 da Lei de Propriedade Industrial do Brasil.A metodologia adotada para este trabalho foi a da triangulação proposta por Minayo e Minayo-Gomez (2003) com abordagem inter-disciplinar. A primeira etapa consiste na revi-são da literatura sobre as funções econômica e distintiva da marca em interlocução com a Comunicação Estratégica, tendo a marca como elemento do composto comunicativo das organizações. Na segunda dimensão, está a recolha de dados junto ao banco do INPI/Brasil. Serão levantados apresentados casos de marcas registradas, com análise qualitativa dos dados levantados e a sua conexão com o suporte teórico escolhido.
Introdução
Descoberto em 1911 por Frederick Forssman, a
expressão do antigénio (Ag) Forssman (Fs) varia
entre espécies, estando raramente presente nos
eritrócitos humanos. Em 1987, três famílias inglesas
sem qualquer relação entre si, foram identificadas
com um fenótipo designado Apae que, mais tarde,
foi classificado como o 31º grupo sanguíneo: FORS.
Os anticorpos (Ac) anti-Fs têm ocorrência natural em
humanos e podem ter implicações transfusionais e
de transplante, uma vez que o Ag está presente na
superfície de eritrócitos, fluídos corporais e órgãos. Objetivos
O principal objetivo deste trabalho foi avaliar a
prevalência de Ab anti-Fs e esclarecer o seu impacto
na medicina transfusional, classificando o tipo de
imunoglobulina (Ig) envolvida.
Materiais e Métodos
Neste estudo foi utilizada a técnica standard de tubo
para avaliar a presença de Ac anti-Fs em amostras de
plasma de uma população de dadores Portugueses
e classificar as imunoglobulinas envolvidas. Foi
utilizada, para a realização de todas as experiências,
uma suspensão de eritrócitos de ovelha a 3-5% com
expressão positiva para Ag Fs.
Resultados
De um total de 11877 amostras, 117 (0,99%)
apresentaram reações fracas (entre 0 e 1 numa
escala de 0 a 4) quando em contacto com o Ag Fs
presente na suspensão de eritrócitos de ovelha.
Essas amostras foram posteriormente estudadas
quanto à presença da mutação no gene GBGT1,
responsável pela expressão da enzima Fs sintetase.
Das 192 amostras estudadas (50 de cada grupo
sanguíneo, à exceção do AB – o mais raro), para
classificar o Ac envolvido, 52% revelaram ser apenas
IgM, sendo as demais, uma mistura entre IgG e IgM. Conclusão
Na população estudada, poucas amostras (<1%)
apresentaram reação negativa contra os eritrócitos
de ovelhas, confirmando a baixa prevalência
deste grupo sanguíneo. Os padrões de reação das
amostras são independentes do grupo sanguíneo
ABO e do género. O Ac anti-Fs é principalmente, mas
não exclusivamente, IgM.
Neste trabalho e na realização do estágio, teve-se como objetivo de estudo, a perceção da realidade de um estágio numa área tão importante e preservada como a Alta-costura. A autora sentiu a escassez de informação e experiências sobre a mesma ao longo do seu percurso académico. Para colmatar, pretendeu executar um estágio na empresa Ana & Belo (BeloSolutions). Perceber como esta consegue suportar o seu atelier e fábrica em Portugal e como são os seus processos criativo e produtivo. Para isto, a autora para além deste estágio, realizou pesquisas sobre as técnicas de alta-costura para perceber a estética e as particularidades desta área. A empresa, não sendo por si considerada alta-costura, a aluna ao longo do estágio, percebeu que foram utilizadas algumas técnicas de “alta-costura”, nomeadamente nos vestidos de noiva, e direcionadas para um produto mais industrial, de forma a garantir uma melhor qualidade e melhores acabamentos.
Para o percurso académico realizado foi utilizada uma metodologia mista, intervencionista e não intervencionista, com carácter qualitativo. Antes da mestranda iniciar o seu estágio, realizou pesquisas sobre as técnicas utilizadas na alta-costura e nos vestidos de noiva, de modo a estar mais instruída sobre a área onde se iria integrar na empresa (vertente não intervencionista). Ao longo do estágio, na vertente intervencionista, a mestranda, foi interagindo com a empresa, onde conseguiu estar presente em várias secções e aprender um pouco sobre a produção das pequenas series de vestidos de noiva, moda casual e EPI´S. Em cada secção, a aluna pode participar, no corte, nos programas Modaris e Diamino, na engomaria, no posicionamento de rendas no tecido, no corte de linhas, etc. Numa fase final, a aluna desenhou algumas peças, sendo que uma destas foi confecionada, com os tecidos restantes de armazém. Em suma, a aluna foi adquirindo conhecimento a vários níveis, incrementando o crescimento profissional e pessoal.
São várias as consequências negativas que o comportamento sedentário acarreta para a saúde do idoso. A
diminuição do tempo sedentário poderia ser um objetivo exequível de forma a alterar os fatores de risco de doenças crónicas e, por isso, conceber, testar e implementar intervenções em idosos orientadas neste propósito é muito importante. Neste sentido, foi realizada uma revisão rápida da literatura, para sintetizar as evidências científicas, que objetiva analisar as estratégias de intervenção que tenham por base a redução do comportamento sedentário diário na população idosa e o aumento dos seus níveis de atividade física. As revisões rápidas contemplam processos metodológicos que permitem apresentar uma síntese de evidências científicas, onde as componentes do processo de revisão sistemática são simplificadas de forma a produzir informação relevante de forma atempada. Foram definidos um conjunto de critérios de elegibilidade, nos quais 8 estudos - intervencionais, randomizados controlados e longitudinais - foram selecionados, sistematicamente, nas bases de dados científicos PubMed e B-On. Posteriormente, procedeu-se a uma análise de conteúdo dos dados extraídos dos mesmos estudos. Os resultados evidenciam que uma intervenção em locais familiares dos idosos que envolvam estratégias educativas de autogestão na redução do comportamento sedentário podem aumentar os níveis de atividade física. Por outro lado, sessões individuais pedagógicas por chamada telefónica ou presencialmente e entrega de folhetos informativos daquilo que pode substituir o sedentarismo revelam ser uma boa estratégia para criar hábitos saudáveis e aumentar a atividade física. Este estudo apurou um conjunto de medidas de apoio para esta situação que se prendem em intercalar períodos de atividade física aos períodos mais sedentários, apostar em medidas que incentivem os indivíduos a movimentarem-se mais ao longo do dia, apesar de participarem em programas de atividade física, e dar conhecimento dos benefícios da atividade física e malefícios que o comportamento sedentário acarreta.
