Abstract Drag crisis has been described as a drop in the drag coefficient (Cd). This procedure was lately assessed in able-bodied cyclists in time trial position by computational fluid dynamics (CFD). Therefore, the aim of this study was to assess the phenomenon of the drag crisis by computer fluid dynamics in transradial and transtibial amputee cyclists in the upright position. A male elite-level cyclist was recruited for this research. The subject was scanned (3D geometry with a 3D Scan) with his competition bicycle, helmet, suit, and shoes. Consequently, transradial and transtibial 3D models were created editing the able-bodied 3D model. To perform the CFD analyses, a domain measuring 7 x 2.5 x 2.5 m (length, width and height, respectively) was created around each bicycle-cyclist model. The domains were meshed with more than 42 million elements. Numerical simulations by CFD were performed in fluent numerical for speeds between 1 m/s and 13 m/s, with increments of 1 m/s. The total Cd decreased with speed. It ranged from 0.84 to 0.55 in the able-bodied, 0.86 to 0.64 in the transradial and 0.90 to 0.61 in the transtibial. The drag crisis phenomenon was observed between 1m/s and 4m/s in all models.

Abstract: Brazilian standards for design of cold-formed steel (ABNT NBR 14762:2010, 2010) and design of pallet racks (ABNT NBR 15524-2:2007, 2007) have different procedures to determine the strength of columns under axial compression, using different buckling curves. This paper aims to evaluate the efficiency of using cold-formed Brazilian standard buckling design curve instead of the formulations of the pallet-rack design standard to study the use viability of the equations in the calculation procedure for computing the uprights compressive strength. This strength was calculated in four ways: one using the original equations of pallet-rack Brazilian standard, and the other three using adaptations of the buckling curve from the cold-formed steel design standard. A theoretical and numerical procedure based on finite element analysis concerning local, global, and distortional buckling and imperfections was performed. Furthermore, experimental results were also consulted to determine the effective area of studied cross-sections considering the effects of local buckling and the presence of continuous perforations. The results show that the proposed modifications are consistently correlated to the results obtained using the original equations of ABNT NBR 15524, indicating the viability of using the buckling curve of ABNT NBR 14762.

ABSTRACT This study aimed to verify the impact of two learn-to-swim programs, implemented for 12 weeks, in age school Brazilian children's aquatic readiness and motor coordination. Thirty-one children aged 7-9 years old (mean± SD 8.00± 0.86 years) were randomly divided into two different experimental groups. One was submitted to lessons mainly focused on basic skills development (BS), and the other was mainly focused on the formal skills of swimming techniques (FS). The aquatic readiness (17 skills) and the motor coordination (Körperkoordinationstest Für Kinder test) were evaluated before and after the interventions. After 12 weeks, the total score of the swimming skills was different between groups (F= 24.19, p< 0.01, ηp2= 0.46), changing from 34.35± 9.22 to 50.18± 8.49 points (p< 0.01, d= 2.60) in the BS and from 36.00± 5.86 to 42.64± 7.46 points in the FS (p< 0.01, d= 1.88). Leg kicking with breath control at ventral and dorsal body position, feet-first entry and deep-water immersion were significantly higher after the training in the BS. The motor coordination scores increased in both the BS (135.57± 37.45 to 172.64± 33.17, p< 0.01, d= 2.11) and FS (130.18± 37.71 to 162.71± 40.40, p< 0.01, d= 1.41). These results showed that both swimming practices improved aquatic readiness and motor coordination, with higher aquatic competence after the lessons that mainly focused on basic skills development.

Resumo Como objetivo deste trabalho, definiu-se analisar os efeitos indiretos de determinantes motivacionais no divertimento e na persistência em praticantes de exercício físico regular. Participaram ao todo 967 praticantes de exercício em ginásio e health clubs, com idades compreendidas entre 18 e 65 anos (M=45,08; DP=13,76). Todos os participantes tinham mais de 6 meses de experiência regular em exercício físico. Os participantes preencheram ao todo questionários traduzidos e validados para a língua portuguesa no contexto do exercício físico, que examinavam a perceção dos comportamentos interpessoais, as necessidades psicológicas básicas, a regulação da motivação e o divertimento. A persistência foi medida através de registos eletrónicos, considerando um praticante persistente aquele que tivesse uma frequência semanal similar aquela auto-reportada no momento inicial. A maioria das regressões são significativas, confirmado os pressupostos da literatura existente. Os efeitos indiretos mostram que o divertimento desempenha um papel crucial na persistência, tanto por via motivação autónoma, como por via motivação controlada. Em suma, atividades promotoras do prazer que os praticantes de ginásio e health club experienciam durante a prática de exercício físico poderão ser a variável chave na persistência a longo prazo.

Abstract The scope of this paper was to analyze the impact of motivational determinants in enjoyment and persistence in physical exercise among practitioners of physical exercise. In total, 967 gym and health club exercise practitioners aged between 18 and 65 (M=45.08; SD=13.76) were recruited for analysis. All participants had more than six months of regular exercise practice. Participants completed and validated scales in the exercise context duly translated into Portuguese, assessing interpersonal behaviors, basic psychological needs, and behavioral regulation. Persistence was measured using computerized records considering persistent exercisers as being those who were exercising at similar frequencies as those self-reported at the initial assessment. Results showed that the measurement and structural model fit the data. Several significant effects were found supporting previous literature. Indirect effects showed enjoyment to play a crucial role on exercise persistence, both by the significant effect via autonomous and controlled motivation. In essence, activities that give pleasure that gym and health club exercisers experience during the practice of physical exercise can be the key variable of long-term persistence.

ABSTRACT The warm-up is fundamental to optimize physical activity and exercise performance. However, little is known about the effect of warm-up in resistance training and strength performance. We performed a systematic review to synthesize and analyze the effects of different warm-up strategies in maximal and submaximal strength during resistance exercises. A search for studies was performed on four databases (Web of Science, Scopus, PubMed, and ScienceDirect) for original research published between May 1973 and December 2019. Eleven articles were selected according to the inclusion criteria. Most of the studies evaluated the effects of warm-up on maximal strength and the number of repetitions until failure. The results were not consensual regarding the use of general warm-up followed by a specific warm-up. Moreover, while some studies showed that specific warm-up did not lead to different results than without warm-up, others found that performing only the specific warm-up was the best way to obtain maximal strength performance. It seemed that the maximal strength and the number of repetitions could be positively affected when a specific warm-up is performed at loads close to the maximum. Further studies are needed to deepen the knowledge about the preparation procedures for optimizing resistance exercise performances.

Resumo Neste trabalho foram avaliadas duas treliças mistas projetadas com perfis tubulares, associadas a uma laje maciça de concreto. Baseando-se em expressões analíticas relacionadas ao problema, seguindo as recomendações de normas, análises numéricas foram realizadas, com modelos criados utilizado o programa computacional Ansys e uma análise experimental, por meio de ensaios em laboratório com a estrutura em escala real. Houve boa aproximação dos resultados nas três análises, sendo observada a possibilidade de falha na conexão de cisalhamento em uma das treliças. Com uma mudança no comprimento do conector da segunda treliça, foi observado um aumento na resistência e na rigidez da estrutura. No estudo, ficaram evidentes os efeitos localizados da ligação entre os perfis em seção tubular e da fixação do conector de cisalhamento diretamente sobre a parede do banzo superior, que causaram plastificações também localizadas.

Abstract In the present work, two composite trusses formed by tubular shapes supporting a concrete slab were evaluated. Based on analytical formulation related to the problem, according to recommendations of standards, numerical analyses were performed, with models created using the software Ansys, and an experimental analysis with full-scale tests. Good agreement between the three analysis types was observed. A possible shear connection failure in one truss was observed. With a change in the second truss's connector length, an increase in the structure's strength and rigidity was achieved. In this study, because the shear connectors were directly welded on the upper chord wall, local effects with localized plastifications were evidenced.

Resumo Há pacientes, denominados de hiperfrequentadores (HF), que utilizam com muita frequência a Atenção Primária à Saúde (APS), ocasionando grande número de prescrições e de referências para outros níveis de cuidados. Este estudo objetivou verificar o efeito das terapias expressivas (TE) no número de consultas médicas e no estado mental em idosos HF. Trata-se de estudo quasi-experimental com amostra de 69 idosos atendidos na APS da Granja do Torto, Distrito Federal, divididos em: grupo de intervenção (GI), com idosos HF; e grupo controle (GC), com idosos não HF. Os idosos HF foram submetidos a TE durante 24 semanas, duas vezes/semana. Na análise dos dados, utilizados testes qui-quadrado de Pearson, análise de variância multivariada para medidas repetidas MANOVA e teste de Lambda de Wilks. O GI apresentou média de idade de 73,97 anos (DP=6,67) e o GC 69,78 anos (DP=6,78), com diferença significativa entre os grupos (p=0,04). Na pós-intervenção, o GI apresentou significativa diminuição da depressão (p <0,001), ansiedade (p=0,05), solidão (p=0,01) e estresse (p=0,006). Ocorreu diminuição significativa do número de consultas no GI (p<0,001) durante o ano seguinte à intervenção. Nos idosos HF, a TE proporcionou efeitos positivos, diminuindo o número de consultas médicas e melhorando o estado mental (depressão, ansiedade, estresse e solidão) desse grupo, oportunizando vivenciarem alternativas para melhoria de sua qualidade de vida. O uso da TE minimizou os agravos de saúde na perspectiva da resolutividade do cuidado com baixo custo, numa abordagem holística de atenção integral ao idoso na APS.

Abstract There are patients, called hyperfrequenters (HF), who frequently use Primary Health Care (PHC), causing a large number of prescriptions and referrals to other levels of care. This study aimed to verify the effect of expressive therapies (ET) on the number of medical appointments and on mental status in elderly FH. This is a quasi-experimental study, with a sample of 69 elderly people attended at the PHC of Granja do Torto, Federal District, divided into: intervention group (IG), with elderly FH; and control group (CG), with elderly people not HF. The elderly HF were submitted to ET for 24 weeks, twice / week. In the data analysis, Pearson's chi-square test, multivariate analysis of variance for repeated MANOVA measures and Wilks' Lambda test were used. The IG showed a mean age of 73.97 years (SD=6.67) and the CG 69.78 years (SD=6.78), with a significant difference between the groups (p =0.04).In the post-intervention, the IG showed a significant decrease in depression (p <0.001), anxiety (p =0.05), loneliness (p =0.01) and stress (p =0.006).There was a significant decrease in the number of consultations in the IG (p <0.001) during the year following the intervention. In HF elderly people, the TE intervention provided positive effects, reducing the number of medical appointments and improving the mental state (depression, anxiety, stress and loneliness) of this group, allowing them to experience alternatives to improve their quality of life. The use of ET minimized health problems from the perspective of resolving low-cost care, in a holistic approach to comprehensive care for the elderly in PHC.

RESUMO: Nesta pesquisa bibliográfica, objetivou-se analisar publicações científicas com a temática educação e cidade, focalizando oportunidades educadoras proporcionadas a jovens na cidade. Através de busca no EBSCO Discovery Service, com os descritores “cidade”, “educação” e “juventude”, selecionaram-se 112 artigos, analisados em nove categorias: 1) Área do Conhecimento; 2) Público-alvo; 3) Área Geográfica; 4) Tipo de Pesquisa; 5) Instrumento Metodológico; 6) Base Teórica; 7) Atividade Desenvolvida; 8) Principais Resultados; e 9) Discussão sobre Cidade. Os resultados revelam diversos usos do território no exercício educativo - variando entre áreas urbanas e rurais, centrais e periféricas -, destacando possibilidades de educar a/com a juventude em práticas urbanas, locais e não institucionalizadas. A escola ainda aparece como central para encontros educativos e criações das juventudes, sendo necessário atividades mais próximas do território. Constatamos significativas experiências educativas territorializadas baseadas na Educação Popular, de Paulo Freire, valorizando os saberes locais, a prática social e relacionando cultura e educação não formal. Concluímos sustentando que as cidades são como arenas interdisciplinares potentes para práticas educativas territorialmente estruturadas, articuladas com vivências e características locais.

ABSTRACT: This bibliographic research aimed to analyze scientific publications with the theme education and the city, focusing on educational opportunities provided to young people in the city. Through a search in a EBSCO Discovery Service, using the descriptors “city”, “education”, and “youth”, 112 articles were selected and analyzed in nine categories: 1) Knowledge Area; 2) Target Audience; 3) Geographic Area; 4) Type of Research; 5) Methodological tools; 6) Theoretical basis; 7) Activity Developed; 8) Main Results; and 9) Discussion about the city. The results reveal several uses of the territory in education - ranging between urban and rural, central and outskirt areas - highlighting possibilities of educating youth through urban, local, and non-institutionalized practices. School still seems central for educational meetings and youth creations, requiring activities closer to its territory. We found significant territorialized educational experiences based on Paulo Freire’s Popular Education, valuing local knowledge, social practice, and relating culture and non-formal education. We conclude by affirming that cities are powerful interdisciplinary arenas for territorially structured educational practices, articulated with local experiences and characteristics.

RESUMO Introdução A Educação Baseada na Comunidade (EBC) no contexto da formação de profissionais da saúde não é um conceito novo, pois sua origem data da década de 1970. Porém, ao longo dos anos, o modo como a EBC é aplicada na educação médica vem sofrendo transformações. No Brasil, desde 2001, a EBC foi incorporada às diretrizes curriculares dos cursos de graduação da área da saúde e, mais recentemente, em 2014, na publicação das novas diretrizes dos cursos de graduação em Medicina. Objetivos Os objetivos do estudo foram levantar os sentidos e significados que os professores atribuem à Educação Baseada em Comunidade nas matrizes curriculares em vigência no ensino médico da Uniceplac no ano de 2016 e identificar possibilidades de aprimoramento do ensino na instituição em consonância com as diretrizes nacionais em vigência. Método Estudo de caráter qualitativo, realizado no Centro Universitário do Planalto Central Apparecido dos Santos (Uniceplac). Os dados foram coletados por meio de entrevista reflexiva com 13 docentes que estão ou estiveram diretamente ligados à EBC nessa instituição no ano de 2016. O método de análise de dados foi a Análise de Conteúdo de Bardin, com a utilização do software Atlas-ti 7 para o suporte na análise. Resultados Os resultados demonstram que a maioria dos docentes afirma conhecer o conceito de EBC, mas sua compreensão diverge da literatura. Além disso, os docentes indicaram falhas na carga horária, nas relações dos professores entre si e com a coordenação, no planejamento e na conquista de cenários adequados das disciplinas ligadas à EBC, além de desafios macropolíticos de aplicabilidade da EBC nos cenários do Sistema Único de Saúde (SUS). Estes resultados estavam relacionados à burocratização das parcerias e a uma falta de corresponsabilidade entre professor, instituição de ensino e Estado. Conclusão Como a EBC vem sendo incorporada gradativamente à educação médica, as instituições também têm uma necessidade crescente de transformação e adequação às diretrizes curriculares vigentes. Sugere-se uma capacitação permanente do corpo docente sobre a compreensão e aplicação da EBC, bem como a criação de um órgão, setor ou funcionário destinado apenas à institucionalização, formalização e manutenção dos cenários, destacando-se cenários da atenção básica no SUS. É também essencial instruir os alunos sobre o tema, para que possam compreender a aplicabilidade da EBC, sua importância na formação médica e sua contribuição para a melhoria da qualidade de vida da população.

ABSTRACT Introduction Community-Based Education (CBE) in the context of teaching health professionals is not a new concept, since its origin dates back to the 1970s, but over the years the way in which CBE is applied in medical education has undergone transformations. In Brazil, since 2001, CBE has been incorporated into the curricular guidelines of undergraduate courses in the health area, and more recently in 2014 in the publication of the new guidelines of undergraduate courses in medicine. Objective The purpose of the present research is to ascertain the senses and meanings that teachers attribute to Community-Based Education in the curricular matrices in force in the medical training offered at UNICEPLAC in 2016 and to identify rooms for improvement in the teaching at the institution in line with the national guidelines. Method A qualitative study conducted at the Centro Universitário do Planalto Central Apparecido dos Santos (UNICEPLAC). The data were collected through a reflective interview with 13 teachers who are or were directly connected to CBE promoted at this institution in the year 2016. The method of data analysis was the Bardin Content Analysis, using Atlas-ti 7 software for analysis support. Results The results show that most teachers state that they are familiar with the concept of CBE, but their understanding of the concept often diverges from the literature. They also indicated failures in the workload, teacher-teacher relationships and teachercoordination relationships, in planning and the provision of adequate scenarios for CBE-related subjects, as well as macro-political challenges concerning the applicability of CBE in practical settings of the Unified Health System (SUS). These results were related to the bureaucratization of partnerships and to a lack of accountability shared between teacher, educational institution and State. Conclusion As CBE has gradually been incorporated in medical education, institutions also have an increasing need to transform and adapt to current curricular guidelines. It is suggested that permanent faculty training on the understanding and application of the CBE be implemented, as well as the creation of a sector or appointment of a dedicated role for the institutionalization, formalization and maintenance of the scenarios, highlighting primary care scenarios in the SUS. It is also essential to instruct the students on the subject so they can understand the applicability of CBE, its importance in medical education and its contribution to improving the quality of life of the population.

ABSTRACT Objective: The aim of the present study was to validate the Basic Psychological Need Satisfaction and Frustration Scale in Exercise for fitness instructors. Methods: Data from 477 exercise professionals (319 males, 158 females) was collected. Results: CFA supported the adapted and validated six-factor model: [χ2(237) = 1096.796, χ2/df= 4.63; B-S p < .001, CFI = .930, TLI = .918, SRMR= .0366, RMSEA = .079 (CI90% = .069, .089)], assessing satisfaction and frustration of basic psychological needs in Portuguese exercise professionals. Moreover, the analysis revealed acceptable composite reliability, and construct validity of the adapted version. Results revealed nomological validity, as well as invariance between male and female. No differences were found across latent means, and magnitude effects were trivial between gender. Conclusion: These results support the use of the adapted scale in exercise professionals, showing measurement invariance between gender. This scale is able to measure how exercise professionals experience satisfaction and frustration of basic needs when prescribing exercise to individuals in fitness context.

RESUMO Neste artigo, apresentamos algumas reflexões sobre os papéis assumidos pelos intérpretes educacionais de Libras-Português na atual educação de surdos em escolas inclusivas baseadas na perspectiva bilíngue. Para tanto, consideramos a contribuição do pensamento bakhtiniano às Ciências Humanas, no tocante ao discurso e à atividade interpretativa, e analisamos trechos de um documento publicado pela Secretaria Municipal de Educação de Florianópolis, que visa à definição das atribuições desses profissionais. Constatamos uma refração na forma de designar os intérpretes educacionais e, também, uma tentativa de delimitação de sua função entre atribuições gerais e atribuições específicas, subdivididas em atribuições com foco no planejamento/formação e com foco no dia a dia da sala de aula. Por fim, concluímos que os papéis do intérprete educacional se definem na fusão da prática interpretativa à ação pedagógica.

ABSTRACT In this article, we reflect on the roles played by Educational Interpreters of Brazilian Sign Language-Brazilian Portuguese in current Deaf Education in inclusive schools that follow a bilingual perspective. Drawing on Bakhtin’s notions of discourse and interpretive activity, we analyze excerpts from a document issued by the Florianópolis City Department of Education, in Brazil, which defines the duties of Educational Interpreters. Our findings point to refraction in how Educational Interpreters are characterized and to an attempt to frame their roles in general and specific duties, some of which focus on planning/training and others focus on the classroom routine. Our conclusions suggest that the role of Educational Interpreters is a merger of both interpreting practices and pedagogical activities.

Abstract This article presents a theoretical and numerical study of an innovative joint using cold-formed steel sections. The motivation for the study of this connection is the ease of manufacturing and assembly that it provides. The profiles are made of cold-formed lipped channel sections, which are welded to form closed built-up sections on the columns and open built-up lipped sections to the beams. The beams use endplates connected by bolts (threaded bars) to the columns. The study evaluates the connection’s initial stiffness of 19 models, where the following parameters were varied: the thickness of the profiles and endplates, the height of the column sections and the diameter of the bolts. A theoretical and a numerical study were developed: the numerical study was performed using finite elements through the commercial software ANSYS, whereas the theoretical study was made based on the component method, prescribed by Eurocode 3, that does not include the design of the connection analyzed herein. Thus, aiming to enable the design of joints composed of cold-formed lipped channel sections, the analysis results were compared and an adjustment coefficient, proportional to the slenderness of the column’s plates, was proposed. The coefficient was introduced to the stiffness component that represents the column web in compression in the mechanical model. The ratio between the coefficients’ numerical and theoretical values presented a maximum variation of 11%, which was considered satisfactory.

Abstract Academic international mobility and intra-European highly skilled migration are consolidated trends. Strongly stimulated by EU policies, the opportunities are highly dynamic, and circulation through different jobs and countries is a striking feature of the academic community. However, for a fragile economy and scientific system such as Portugual’s these trends are synonymous with brain drain, particularly in times of Eurozone crisis. To study the role of the economic crisis in scientists’ decision-making process, in terms of their own migration, five individual portraits are analysed, taking into account that academic mobility is often associated with individual career perspectives and encouraged by European policies.

Resumen La movilidad internacional académica y la migración intraeuropea altamente cualificada son tendencias consolidadas. Vigorosamente estimuladas por las políticas de la UE, las oportunidades son dinámicas y la circulación a través de diferentes puestos de trabajo y entre países es una característica destacada de la comunidad académica. Sin embargo, debido a que la economía y el sistema científico son frágiles en Portugal, esas tendencias son sinónimos de la fuga de cerebros, particularmente en tiempos de crisis de la zona euro. Con el fin de cuestionar el lugar de la crisis económica en el proceso de tomar decisiones de la migración de los científicos, se analizan cinco retratos sociológicos, considerando que la movilidad académica suele estar asociada con perspectivas de carrera individuales y es fomentada por las políticas europeas.
