Olympic and paralympic games Rio 2016: a technical-tactical analysis of judo matches

The purpose of this study was to compare the athletes’ scores, penalties and efficiency between the Olympic and Paralympic Games Rio 2016, and identify which variable determined the winner of the matches. A total of 608 matches in the Olympic and Paralympic Games were analysed. Total relative scores (ippon, waza ari and yuko), penalties (shido per match) and efficiency were identified in the male and female categories, Olympic and Paralympic Games, and medallists and non-medallists. The main results showed that waza ari was higher in the Olympic Games (p=.05) than in the Paralympic Games (male team); ippon was higher in the Paralympic Games (p=.05) and shido was higher in the Olympic Games (p=.05) (female team). The male Olympic medallists were more efficient (p=.01), while the female Paralympic medallists were less penalised (p=.01). Ippon was the key variable that determined winning in both the Olympic and Paralympic matches (p<.001). We concluded that the male Olympic judo athletes showed greater efficiency and scores than Paralympians, while the female team presented more scores and fewer penalties. Ippon was the key point that determined victory in most of the matches

Social scientists in the Brazil's National Health Service

Although there is a tradition of social scientists working in the health sector in Brazil, the workforce and its contribution remains almost completely invisible. This article discusses the results of two complementary investigations, conducted in 645 municipalities in São Paulo state, into the views of healthcare managers and social scientists concerning their work in Brazil's National Health System. The study concludes that the entry to work in the health sector is unplanned and that the invisibility, colonization and alienation of this workforce are generated by internal factors within both the health sector and the social sciences themselves.Embora exista uma tradição de cientistas sociais atuando no campo da saúde no Brasil, essa força de trabalho e suas contribuições são praticamente invisíveis. O objetivo deste artigo é discutir os resultados de duas investigações complementares, realizadas nos 645 municípios do estado de São Paulo, a fim de compreender a visão dos gestores de saúde e de cientistas sociais sobre o trabalho desses gestores no Sistema Único de Saúde (SUS). Concluiu-se que o ingresso para o trabalho no campo da saúde não é planejado e que a condição de invisibilidade, colonização e estranhamento dessa força de trabalho é promovida pelas internalidades tanto do campo da saúde como do campo das ciências sociais

Injury prevalence in Brazilian jiu-jitsu athletes: comparison between different competitive levels

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse

PRODUCTIVITY AND ENERGY EFFICIENCY OF WINCHING OPERATIONS IN PINE STANDS IN MOUNTAINOUS REGIONS

The objective of this study was to evaluate the productivity and energy efficiency of tree extraction in mountainous regions by means of a tractor with winch in two work team compositions: I: one tractor operator and a cable operator; and II: one tractor operator and two cable operators. The study was carried out in Vale do Ribeira region using a full tree harvesting system through a time and motion study in different conditions of extraction distance (6 to 135 meters) and log yard (5 to 241 meters), and land slope (from 7 to 37º). To evaluate the cycles, a regression analysis was carried out for each treatment and subsequently compared using the Graybill F test. Then a regression with a dummy variable was performed. The productivity was 9.26 m3 PMH0-1 with a cable operator and 12.12 m³ PMH0-1  at an extraction distance of 100 m; the specific fuel consumption was 44.26 g kW-1 PMH0-1  in both treatments, and the energy efficiency was 4.92 g kW-1 m³ with a forest worker and 3.13 g kW-1 m³ with two forest workers. Consequently, although the specific fuel consumption was equal in both treatments, the increase in productivity resulting from the addition of a cable operator,improved  the energy efficiency in the extraction using a tractor with winch

Teorias de Aprendizagem em Jogos Digitais Educacionais: um Panorama Brasileiro

Este estudo tem por objetivo identificar as teorias de aprendizagem aplicadas em jogos digitais educacionais desenvolvidos no Brasil no período de 2004 a 2014. Foram analisados 27 artigos selecionados com o auxílio da base de dados do Google Acadêmico, para isso, foram utilizados dois grupos de descritores. Na amostra, em 41% dos casos não foi identificada a aplicação de teorias de aprendizagem no desenvolvimento de jogos digitais educacionais. No restante da amostra, a teoria de Piaget é a mais citada, presente em 22%. Em segundo, as teorias de Vygotsky aparecem em 15% das fundamentações teóricas. A concepção pedagógica adotada nas pesquisas da amostra condiz com o estado de arte internacional, isto é, uma preferência por teorias de base Construtivista. Entretanto, a Teoria de Aprendizagem Experiencial de Kolb, mais presente nas pesquisas internacionais, não é identificada na amostra

Study of High-Performance Engineering Polymers Applied In Reciprocating Hermetic Refrigeration Compressors

Manufacturers of hermetic refrigeration compressors for domestic and commercial applications have been increasing the energy efficiency of their products systematically over the last decades through the continuous efforts of in-house research groups, universities and suppliers. This joint effort encompasses the technical fields of design, materials, processes, manufacturing, and simulation techniques, to achieve a multidisciplinary approach to compressor optimization as applied to refrigeration systems. Gains such as increased efficiency of the electric motor, reduction of bearing friction power loss, minimizing back flow on valves have already been addressed and the continuous search for new approaches have been proposed. This work presents a study of energy efficiency gain by comparing low conduction heat transfer plastic materials to metallic materials used in current compressor designs. The components compared include the cylinder head, discharge muffler, shock loop, valve plate and crankcase. The energy efficiency gain was evaluated using the Coefficient of Performance (COP) through the use of the Conjugate Heat Transfer (CHT) model using superheating temperature. The CHT model temperature results were compared with the values measured by an instrumented compressor. To complement the study, the parts and assemblies were structurally evaluated using the finite element method under performance and durability test operating conditions. The feasibility of the mold filling process was verified, because the final design of the components must be a compromise between functional requirements and process solution. In conclusion, the results show that significant efficiency gains can be achieved through the use of engineering thermoplastic. This is achieved through careful material selection and proper design that considers not only material properties, but material and process costs using the flexibility of injection molding to group parts and subsystems
