Os autores utilizam como ponto de partida as diretrizes da formação básica do professor da Educação Física, pressupondo que essas diretrizes exigem tanto uma nova mentalidade quanto uma nova organização didático-curricular, além da revisão dos próprios referenciais na prática profissional. A partir daí, desenvolvem uma série de questionamentos, debatendo se o novo currículo de formação em Educação Física - que passou a valorizar mais a prática - consegue de fato ir além do modelo acadêmico que privilegia uma formação teórica mais sólida. Discutem ainda se uma maior valorização da prática pode caracterizar a existência de um novo modelo de formação. Dessa perspectiva, perguntam se é possível um currículo que não tenha na sua base a pedagogia da alternância, um sistema que remete à formação em dois contextos distintos e interdependentes: a formação em sala e as situações de trabalho. Também perguntam como a discussão dos saberes - conhecimentos, competências, habilidades e didática de ensino - deveria se desenrolar nessas duas esferas

The model used in Brazilian schools, based on both traditional and progressive education, transmits information without worrying to show the real meaning of things, and without taking into consideration the previous knowledge of the pupil. How to work with the contents of human knowledge in a meaningful way? One alternative way is the Methodology of Dialectical Mediation (MDM), which consists in four steps or pedagogical moments, rescuing, problem posing, systematizing and producing. This theoretical option considers the educational work as a relationship involving teaching, learning and contents, which are taken as independent moments tightly connected to the ongoing work, instead of isolated elements or static terms. The aim of the present work is to clarify the Methodology of Dialectical Mediation and develop a class proposal according to the MDM approach to the problem of the free falling bodies (gravity, material means and shape). To evaluate the methodology, questionnaires were applied after experiments, with the involvement of students at each predominant moment. The results suggested that the MMD, combined with experimental activity, is a tool that enhances the overcoming of immediate knowledge, allowing students to reach a better understanding of the scientific knowledge.

The oral cancer model in hamsters shows many simílarities with developmental oral cancer in humans. The proliferating capacity is one the most characteristics of neoplásica ce/Is and detection of these ce/Is allow us, throughout of its counting, to achieve an estimated tumour growing index, with a consequent repercussion about prognostic and in the treatment of those lesions. 40 golden Syrian hamsters, both genders, aged between two to six mouth and weight 150g in average were used. The left síde of tangue of each animal was painted for eight consecutive weeks, with a solution of DMBA. Tongues were removed, fixed in 10% buffered fonnal solution. The histological slides were stained by AgNOR technique and by PCNA and β-catenin immunohistochemical antibodies. Statistical analyzes were performed by ANOVA one-way test and Tukey test. We may conclude that an association between AgNOR and PCNA might indicate the higher proliferating activity of the analyzed celIs. The experimental carcinogenesis model in hamster tongue is an available methodology for immunohistochemistry study. And finally, PCNA and β-catenin immunohistochemical antibodies may be used to analyze possible premalignant areas in oral leukoplakia

The Cu-Au mine of Chapada is located in the municipality of Alto Horizonte, in the northwestern portion of Goiás state and is inserted in the geological context of the Brasilia Belt, specifically the Mara Rosa Magmatic Arc, which hosts important deposits of Au and Cu-Au. The rocks found in the study area belong mainly to the Volcano-Sedimentary Sequence of Mara Rosa and are composed of basic to acidic metavolcanic rocks, psammiticpellitic metasedimentary rocks, chemical rocks and also hydrothermal products. Late intrusions occur and are represented by pegmatitic dikes and tonalitic bodies. The ore deposit of the Chapada mine is formed predominantly by the chalcopyrite-pyritemagnetite association, where pyrite is the most abundant mineral. Through the structural mapping of the mining fronts, it was able to recognize three deformational phases (Dn, Dn +1, Dn +2). During the Dn phase, isoclinal recumbent folds were formed, in association with amphibolites facies metamorphism. Later, in phase Dn +1, there was formation of drag folds and intrafolial folds in association with retrograde metamorphism in the greenschist facies. The deformational phase Dn +2, in its turn, was responsible for late symmetrical folding of the foliation, with NS and EW axes, resulting in an interference pattern of the dome-and-basin type

Introdução: A prevenção e o controle das DCNT’s adquiridas com a prática regular de atividade física podem contribuir para a melhora da saúde dos indivíduos, e consequentemente, pode colaborar na redução do uso dos serviços de saúde e nos gastos referentes a esse serviço além de refletir uma melhor qualidade de vida do indivíduo. Objetivo: 1) Descrever as consultas realizadas pelos participantes do programa e 2)Analisar a influência da atividade física na utilização dos serviços de saúde. Metodologia: Esse trabalho é de caráter retrospectivo e transversal, e foi desenvolvido em Unidades de Saúde da Família no município de Rio Claro, SP. Dentre as 250 mulheres participantes do Programa de exercícios físicos em unidades Básicas de Saúde e Unidades Saúde da Família (USF), com faixa etária acima de 20 anos, foram selecionados dentre essesparticipantes aqueles que possuam prontuários nas sete Unidades Saúde da Família, totalizando 48 prontuários. Foram analisados 1350visitas às unidades no total. Foi analisado o uso dos serviços de saúde através do número de visitas ás unidades de saúde comparando os dados encontrados no ano anterior e no ano posterior do início do programa. Foi utilizado o Termo de Consentimento Livre e Esclarecido para os participantes da pesquisa. Foi realizada análise descritiva dos dados, utilizando-se frequência, média, desvio-padrão máximo e mínimo. Foi realizada análise de comparação dos dados contínuos. Resultados: O grupo participante do Programa Saúde Ativa Rio Claro eram em sua maioria idosos, com alto número de doenças crônicas, principalmente hipertensão (60,4%) e diabetes (37,5%), no entanto, menos da metade com uso de medicamentos para essas doenças. A maioria das consultas eram agendadas (61,7%) ou eram realizadas para triagem/acolhimento (23,0%), com uma menor frequência para controle de pressão arterial ou glicose (5,2%). Os sujeitos analisados...

Our purpose is to show the effects in the predator-prey trajectories due to parameter temporal perturbations and/or inclusion of capacitive terms in the Lotka Volterra Model. An introduction to the Lotka Volterra Model (chapter 2) required a brief review of nonlinear differential equations and stability analysis (chapter 1) , for a better understanding of our work. In the following chapters we display in sequence our results and discussion for the randomic pertubation case (chapter 3); periodic perturbation (chapter 4) and inclusion of capacitive terms (chapter 5). Finally (chapter 6) we synthesize our result

In our experiments, we studied the classical dynamic of a particle in vertical motion subject to a constant gravitational field and the partial shock with an elastic wall with oscillatory motion located below the particle. The motion of the particle was confined to the vertical direction by a glass guide tube, which was initially evacuated, allowing viscous drag forces to be disregarded. The time between impacts, as well as the time between the reference phase of the movement of the base and the moment of impact and the period of oscillation of the base will be acquired by a hardware and software to obtain the phases space to be compared later with the description of the system through mapping discrete variables via the 'particle velocity immediately after shock 'and' phase of the movement of the base at the instant of shock 'obtained by computer simulation. This requires developing an electronic analog system followed by Digital implemented in reconfigurable logic, more specifically a sequential machine able to discriminate the impact with the metal base from the impacts of the glass guide tube, based on the frequency spectrum of the response of the microphone to these different impacts

Introduction: Physical inactivity is identified as the fourth greatest risk factor of mortality worldwide. Little is known about how physical inactivity alters the demand for use of primary health care services, and it is a subject which demands further investigation. Objective: This study aims to determine the influence that physical activity has on the demand for use of primary health care services. Methods: This is a retrospective and cross-sectional study. The Rio Claro Active Health Program (SARC), studied in this research, is a partnership between the Municipal Health Foundation and Universidade Estadual Paulista Julio de Mesquita Filho (UNESP), represented by the Nucleus of Physical Activity, Sport and Health (NAFES) department of Physical Education and coordinated by Prof. Dr. Eduardo Kokubun. The study was carried out on residents of Rio Claro of both sexes seen at SARC. To assess the influence that physical activity had on the demand of the use of health services a questionnaire was given to participants who had attended the program since 2009. This questionnaire contains questions concerning the level of physical activity, health service use, number of both blood pressure and glucose measurement takings, number of spontaneous and scheduled medical visits, number of medications taken, number of illnesses and hospitalizations, comparing the data found in the previous year and the year after the program began. An informed term of consent was used for research participants. Descriptive analysis was carried out, using frequency, mean, maximum and minimum standard deviation. Results: Active participation in The Rio Claro Active Health program has positively influenced the following variables: perception of health, uncontrolled blood pressure, did not modify the number of diseases, number of medications in general, ...(Complete abstract click electronic access below)
