Nuclear Medicine is a medical modality of therapy and diagnostic imaging using unsealed radioactive sources for its purposes. This routine activity promotes the transit of radioactive sources for the area of installation, beyond the transit of patients injected with radioisotope, which also contribute to raising the radiometric level of environment. As a consequence, it has exposured workers and public individuals to the ionizing radiation. There are protective mechanisms of radiation exposure, personal protective equipments, and measurement planes established in standard measurement at certain points of the environment in order to identify any increase in radiometric levels and \ or contamination, but do not cover the entire space occupied by workers and patients. To accomplish with the individual dose limits established by the National Commission of Nuclear Energy, it is interesting if there is an individualized classification for each Nuclear Medicine service. This work aimed to promote an analysis of the radiometric level distribution across the extent of the Technical Nuclear Medicine Sector of Hospital of the Botucatu Medical School, and produce a spatial map to identify locations with higher exposure rate to the ionizing radiation, can be used as a risk map to assist the Occupationally Exposed Individuals (IOE). To perform the radiometric levels checking it was used a digital Geiger-Muller detector available in the sector, due to its practicality compared to other detectors. Measurements were carried out at four different times for all days of the week, at points strategically established to cover all the installation

The process of product development (PPD) is a strategic factor in which companies seek to identify consumer needs. The relationship of the practices adopted, tools, techniques, among others, can determinate the maturity level of the company in this process. The purpose of this paper is to understand and diagnose the level of maturity of the PDP in footwear segment industry. For the case study, a company inserted into one of the largest poles of women’s footwear in Brazil, located in Jaú, São Paulo State, was researched. The diagnosis is based on the maturity levels of the unified model, reference in the process of product development, proposed by Rozenfeld et al. (2006). The application of the model assisted to diagnose the current maturity level of the company in this process, providing useful information to achieve higher levels of maturity in the PDP.

This paper proposes some reflections from activities developped in the context of a research supported by FAPESP called “As políticas de educação profissional e tecnológica no Brasil pós LDB 9394/96”. Our purpose is to analyze the federal legislation of professional and technological education, by enphasizing its impacts in technical schools of São Paulo (Brazil).

In this paper, I will present a proposal for teachers’instrumentation in ICT by the configuration of a virtual learningenvironment (MOODLE) for advising Linguistics graduate students’projects on teacher education and language teaching mediated by digitaltechnologies. The context of the proposal is teaching as work,occasioned by an announcement from the IHE to encourage the use ofICT. Following the theoretical assumptions adopted by the ALTERresearch group, and confronted with the goals set in the text of theannouncement, the instrumentation involved the reorganization ofcontents provided by a graduate course in the research process steps:planning, implementation and dissemination, and of the artifactsaffordances: information, communication and production.

A comparação visual com escalas de cor, universalmente empregada para avaliar o resultado das diferentes substâncias, técnicas e aparelhos utilizados no clareamento dental, tem se mostrado um método limitado, questionável, subjetivo e pouco confiável. Os métodos instrumentais, que utilizam espectroscópios ou imagens digitais, têm se mostrado mais adequados por oferecerem avaliações objetivas, maior reprodutibilidade e confiabilidade. Neste artigo, serão apresentados e discutidos os resultados obtidos com a utilização do ScanWhite© ? software para avaliação objetiva do nível de clareamento dental e apoio à decisão clínica, que baseia sua avaliação no processamento computacional de imagens digitais. Esse tem como principais diferenciais: (1) algoritmo calibrador para compensar as variações de luminosidade do ambiente, (2) apresentação dos resultados em valores numéricos e através do gráfico de evolução do clareamento dental, (3) interface intuitiva e facilidade de uso, (4) determinação dos índices de apoio à decisão (IPS ? índice de possibilidade de sucesso, e IRS ? índice de risco de sensibilidade antes do início do tratamento) e (5) emissão de relatório geral, autorizações e recomendações pós-clareamento.

Futsal is one of the most popular sports in Brazil, played on five continents, in hundreds of countries, but is still a poorly studied sports science. Among the types of training used in the preparation of soccer players, the collective training is one of the most used because it is a simulation game. The application of the training load is often made in large quantities (volume) with exercise duration and intensity greater than what the athlete can handle. Thus, this study aimed to evaluate the intensity of physical exertion of futsal players of basic category during collective training. We evaluated twenty (N=20) soccer players from two teams with different levels of training. There were ten players on a team federated (FED) and ten players on a team for a project extension (EXT). Samples were collected at the respective locations of training. An evaluation of anthropometric and during collective training heart rate was measured and at the end of each training time blood samples were collected for analysis of blood lactate concentration and perceived exertion of the players. There was significant difference between the two teams only in fat percentage (FED=13,4 e EXT=21,2). The average heart rate during training was 174 ± 12.2 bpm, which corresponds to 84% HRmax. There was significant difference between heart rate and the percentage of HRmax in the two parts of training in both teams. The Federated team players remained most of the time in more intense intensity zone (above 85% HRmax), while the EXT players were most of the time zone of moderate intensity (65-85% HRmax). The rating of perceived exertion (FED=3,5 e EXT=3,2) and blood lactate concentration (FED=2.4 mmol/L and EXT=2.9 mmol/L) showed no significant difference between the two teams and between the two times. During training there was a significant correlation (p= 0.71) between heart rate and lactate concentration. The collective training showed an intensity that is supposed to be...

Regular physical activity can prevent and treat various diseases and non-communicable diseases such as diabetes, hypertension, obesity and cardiovascular disease. However, the prevalence of physical inactivity among adolescents in Rio Claro is 83%. Thus, it is necessary to encourage physical atividade through the community, especially parents and schools. The objective was to investigate the influence of two types of gym class in functional abilities in high school students in the city of Rio Claro-SP. Methodology: The study included 20 students from high school, 8 boys and 12 girls. The study took place in two high school halls of a public school in the city of Rio Claro. With the collaboration and participation in only 10 students in each room search reviews of all students occurred in mid-July in the year 2012 with the completion of the battery of tests and application of PAQ-C questionnaire at the beginning of classes of and after three months. All students were subjected to the test battery Eurofit. To compare the values of physical fitness for each type of class was held factorial ANOVA for repeated measures using SPSS and the level of physical activity was performed the Wilcoxon test. To compare the delta values (post-test-time time pre test every physical fitness) we performed the t test for all analyzes was adopted p <0.05 Classes G1 followed the schedule proposed by the state 's Notebook, where he worked subjects as body and beauty and its relationship with the media today, prevailing more conceptual classes than procedural . Unlike what has been developed with the G2 who had classes were focused on physical fitness and physical conditioning to increase the level of physical activity inside and outside the school environment . Result :The results from the data collected in this study indicate that physical fitness is not worked continuously or expressive within the Physical Education classes of high school to the population...
