Análise estrutural do suporte de pastilha de grafite para lubrificação de roda ferroviária

This study aims to structurally evaluate a support of graphite pastille for the lubrication of railway wheels. The proper lubrication of wheel flanges of the railway extends the life of this component, so it is very important that this occurs lubrication to reduce the costs involved in railway maintenance. To prepar the evaluation structural will be used to International Electrotechnical Comission standard (IEC 61373) establishing which load cases should be applied to this component. The applied loads on the support (accordance with IEC) are random accelerations and accelerations due to shocks, thus simulating the conditions that exist along the route of the train. The structural analyzes are performed by the finite element method, with the aid of the Cosmos software. Thus, it is possible to determine the stresses acting on the support, and so the allowable stresses compared with the standard proposed by the AISC. The stress in the structural analyzes are lower than allowable therefore considered for the configuration presented, unexpected structural problems

Orientação espacial em pessoas com deficiência visual: um estudo de triangulação por meio de monitoramento remoto

This study was conducted to investigate how visually impaired people perform distance estimation tasks by movement and navigation during deprivation of effective perceptual and proprioceptive information. For that they performed the task of walking three distances, being the first and second of 100 meters and the third of 140 meters (triangulation) from a point of origin in open field on a inverted L shaped trajectory and then returning to the origin. The first and second tasks were driven by means of a guide with GPS adapted to the study coordinates, and the third one was freeform with three sessions, the first without perceptual and proprioceptive restrictions, the second without auditory perception, and the third in a wheelchair, without proprioception. The objective of this study was to indicate the differences in distance reproduction in relation to accuracy and investigate the spatial representation of participants in a navigation task, in which there is active movement, but no effective perceptual and proprioceptive information. Results showed that the average participants underestimated distances producing average angles close to the value of 45°. And by means of the "t" students test no significant differences between subjects can be pointed out. To achieve these results we used remote monitoring by GPS and software TrackMaker.

Tarefas de triangulação com restrições perceptuais em pessoas com deficiência auditiva: um estudo por meio de gps

This study aimed to investigate how people with hearing disability perform tasks of distances estimation for locomotion and navigation when deprived of effective perceptual and proprioceptive information. For this, participants with hearing disability went three distances being the first and second 100 meters and the third 140 meters (triangulation) from a source point in an inverted L open field trajectory and then returned to the origin, and the first two were driven by a researcher guide with adapted GPS coordinates of the study, and the third being three free-form sessions, the first one without any perceptual and proprioceptive restriction, the second without visual perception, and the third on the wheel-chair, that is, without proprioception. The results showed that people with hearing disability without the knowledge of the path do not possess satisfactory accuracy but when they learn the way even with the restriction of visual perception and proprioception they can return to the starting point in a task of triangulation. The "t" students test with a significance level of 5% (2.131) indicates significant differences between the first task without any perceptual restriction and the third where they performed in the wheelchair. To achieve these results we used remote monitoring via GPS and the TrackMaker software.

A interlíngua e o alinhamento léxico-conceitual da base de dados bilíngue REBECA

In the architecture of a natural language processing system based on linguistic knowledge, two types of component are important: the knowledge databases and the processing modules. One of the knowledge databases is the lexical database, which is responsible for providing the lexical unities and its properties to the processing modules. The systems that process two or more languages require bilingual and/or multilingual lexical databases. These databases can be constructed by aligning distinct monolingual databases. In this paper, we present the interlingua and the strategy of aligning the two monolingual databases in REBECA, which only stores concepts from the “wheeled vehicle” domain.

Elaboração de um Jogo Digital Educacional sobre Saúde Bucal Direcionado para a População Infantil

Objective: The aim of this study was to develop an educational oral health digital game for 5-to-7-year-old children. Method: The game, called “Dr. Trata Dente”, was based on the approach to three different oral health-related topics: a) bacterial plaque and the main diseases caused by it; b) oral hygiene methods for bacterial plaque control; c) dental caries and preventive measures for this disease. These topics were discussed in sequential order in three different stages of the game. Dr. Trata Dente is represented by the figure of a little super-hero dentist, who talks to the children about oral health during the game. The game is sub-divided according to its propositions to the children, into an association game, a memory game and a coloring game. After its development, the game was evaluated by three professionals of each of the following areas: Dentistry, Pedagogy and Psychology (n=9), who verified the suitability of the concepts presented in the game as regards oral health, linguistic abilities worked with the children, fulfillment of the intended didactic criteria, and the playful aspect of the game. Results: According to the dentists, the dental concepts presented in the game are adequate. According to the pedagogues, the choice of a super-hero was correct and the given explanations are well elaborated, organized and have accessible language, although long. For the psychologists, the game has a potential positive effect on the children’s learning, but there should be more interaction of the character with the children. After this evaluation, changes were made in the game according to the professionals’ suggestions. Conclusion: It was concluded that in spite of the suggested alterations, the game is suitable for teaching oral health by means of children’s play.

Apoiador matricial: uma possibilidade de promover a interdisciplinaridade entre profissionais da saúde

This study aims to reflect the organization of the mental health services in primary care from a new organizational arrangement to health work, defined as Matrix Support (Campos, 1999), which aims to build technical and educational support in the relationship between health professionals from mental health professionals in the Family Health Strategy. The methodology used in the Matrix Support the “Wheel” method, which is mediated by a supporter who, through questions and reflections, points out possibilities for case discussions, promotes links between the health teams, discusses the concept of link between professionals and users, strengthens the co-responsability for the actions of health and tries to break the logic related with the services organized by referrals. So the wheels when they occur in health services enables the interdisciplinary, and through it, it is expected to talk about the complexity of the phenomena that surround each subject, so that they overcome the dichotomy between individual and collective, social and biological revealing new values to be incorporated into health practices. In front of this analysis that is theoric and conceptual, allied with the experience from a nursisn area professional that worked in this work method, can be concluded that this experience related here, eas strategic for the health care actions for strengthen based on the Unique Health system and Psych Rebuild principles.

The effects of environmental enrichment on biochemical and metric parameters of aged rats

The enriched environment (EE) is a promoter of physical activity, by its characteristics such as ample room for movement and exploration, presence of wheels, tunnels and toys. The maintenance of animals in enriched environment can bring a range of benefits, but the majority of the researches investigate cognitive parameters and changes related to the nervous system. The aim of this study was to examine the effects of the maintenance of aged rats in enriched cages on biochemical and metric parameters. Wistar rats were randomly distributed (n=6) into two groups during 6 weeks: control (C) in a conventional cage and enriched environment (EE). The body mass were recorded weekly and the body length at the end of the study. After euthanasia, blood was collected for analysis of glucose, triglycerides and the brain was collected for analysis of mass. The EE group had higher brain mass and lower gain of body weight compared to control group. The control group animals had normal values of blood glucose and triglyceride levels, and the maintenance in an EE did not promote changes in these parameters. Therefore, it can be concluded that the EE group increases brain mass and reduces the gain of body weight without changing the blood glucose and triglycerides in aged animals.

Criação de contexto favorável ao compartilhamento do conhecimento operário: pesquisa no ambiente vidreiro

In search for better competitiveness, the automotive industry has discussed and applied several concepts related to people and processes. However, in many organizations, the adopted concepts are implemented and kept unarticulated. In this context, authors recognize the role of the knowledge as competitive advantage, but it is still dealt in an implicit way with the traditional models of Production Management. Exploring opportunities in this scenario, this Thesis aims to analyse worker knowledge sharing using factors of Knowledge Management, Work Organization and Production Organization. For the realization of the present Thesis, the scope of the research was restricted to be the labour environment of the glass plants shop floor. The choice of the glass sector is justified due to high dependency on the tacit knowledge of blue-collars. The research uses a qualitative-quantitative approach and employs interviews with workers and managers to identify factors. To assess the importance of these factors in the management judgments, is employed the technique Incomplete Pairwise Comparisons based on Analytic Hierarchy Process Saaty (2001). The result indicates integration among factors and highlights the importance of systematic and technical conversation among operators to share better your knowledge. Also, worker knowledge sharing is improved using communication, training and work instruction. This research extends the conceptual frameworks encountered in literature from the factors integration of Knowledge Management with the Organization of Work and the Production and makes explicit use of the theme of knowledge. This contributes to promote of a favourable context for the creation and sharing of knowledge, among the people in the labour environment, and to support incremental innovation
