The dance is one of the cultural content of body movement. But it is known, by means of literature and researches, that the training of teachers of Physical Education has submitted this content limits, damaging their future education in schools. This article discusses these limits and their possible solutions, ruled itself for both in literature and analysis on data collected in search of the Masters PEREIRA (2007). In this analysis it was felt that the dance is little in this Fitness because of graduate students have little experience inside and outside the school environment, because many parents, teachers and students have to dance with prejudice, and because do not feel prepared to deal with this content in schools. It appears that this may be due to the hegemony of sports in physical education, and some misunderstandings when you think the goals and content of dance in physical education.

The use and the demand for substances that enhance masculinity, strength and sexual power are not novel. Over the years, this search has assisted the research directions in this area, leading to the discovery of the primary male sex hormone testosterone in 1935. Since then, numerous testosterone analogue compounds were synthesized, which are generically called Anabolic Androgenic Steroids (AAS). The AAS were produced for therapeutic purposes, but an increase in the use of these compounds for other purposes occurred over time. Initially they were used mainly to improve performance in athletes. However, recent studies have shown that the use of AAS by non-athletes with aesthetical purposes have been increasing as well. The abuse of AAS with non-clinical purposes can promote a number of physiological alterations, such as heart, liver, respiratory and psychological problems such as changes in mood, levels of anxiety and aggression. Exposure to supraphysiological doses of AAS is associated with behavioral changes, however, little is known about the effects of AAS on cognitive functions. In this work, we aimed to mimic the AAS abuse in humans with intramuscular administration of a supraphysiological dose of testosterone propionate (TP) in rats. We investigated the effects of this treatment on different aspects of cognitive function, specifically learning, memory and anxiety. Adult male Wistar rats were tested in the spontaneous alternation, novel object recognition and plus-maze discriminative avoidance tasks. The control group received intramuscular injections of vegetable oil (vehicle), and the TP group received injections of TP (10 mg/kg, i.m.). The injections were administered for 40 days, with intervals of 48 hours (chronic treatment) or in a single injection (acute treatment). In addition to the behavioral assessments, we performed biochemical analyzes as indicators of the endocrine effects of the treatment. Our results show that chronic treatment with a supraphysiological dose of TP caused memory impairments in the novel object recognition and the discriminative avoidance tasks. The spatial working memory (evaluated by spontaneous alternation task) was not affected. Also, we did not observe changes in anxiety levels. Regarding the biochemical parameters, chronic treatment increased serum levels of glutamicpyruvic transaminase, an indicator of hepatic and pancreatic lesions (as those observed after chronic use of these substances in humans). On the other hand, acute treatment with PT did not promote significant changes in any of these parameters when compared to the control group. In summary, we conclude that chronic treatment with a supraphysiological dose of testosterone propionate produces memory deficits in novel object recognition and retrieval of the discriminative avoidance task in adult male rats

This research aimed to analyze the dynamics established between the activity of the teacher in Distance Education (DE) and professional gender of teaching, in terms of impact of DE in teacher s usual professional activity. Previous studies showed that one of the central discussions concerning DE refers to the role that the teacher is called to perform. The present research, based on theoretical and methodological assumptions issued from Clinic of Activity, analyzed the impact referred above. This central aim was operationally executed along three main stages: 1) survey study for description of socio-professional profile of teachers working in DE in two universities from Natal (RN-Brazil), 2) clinical analysis of professional activity of teachers working in DE, taking into account four simultaneous levels of psychological constitution and development of human activity: personal, interpersonal, transpersonal and impersonal; 3) analytical focus on transpersonal context in order to understand the influence of pedagogical practice in DE on professional gender of teaching. Documental research, audio recorded voice data and a multiple choice Likert scale questionnaire concerning socio-professional information were used as procedural tools. The qualitative-clinical procedural tool of instruction to the double , firstly proposed by Clinic of Activity research group, was used in order to obtain oral productions concerning professional activity. Data issued from stage 1 (n=70, 28 men and 41 women) was submitted to descriptive and inferential statistical analyzes. 65.7% of the sample worked in a public institution, 30% in a private institution, and 4.3% in public and private institutions. 31.4% of the sample of participants was formed by teachers having a master degree, 28.6% were doctors and 26.3% had degrees of specialists. 54.3% of participants acted as remote tutor, and 44.3% were regents teachers. After descriptive multidimensional cluster analysis, two groups emerged (remote tutors and regents teachers), the most important variables in terms of contributions to this distinction being: professional function, level of graduate formation, level of income, activities and forms of entry in DE. Clinical analysis of data produced by two participant-teachers of each group, issued from instruction to the double technique, was performed. This analysis indicated the existence of different models of distance education. A general concern referring to the need of both taking into account information technology and pedagogical attitudes was detected. On the other hand, participant-teachers considered that participation in DE activities could bring relevant contributions to general professional gender of teaching. . Finally, teachers warned against certain formats of organization of teachers professional activity, as found in the domain of DE, since these activities could promote the intensification and individualization of teachers` work activity, and even the worsening of relations, rather than exchanges and shares through collective bargaining. This process could compromise the renew of the professional gender, by losing its historical roots and diminishing activity possibilities of teachers in their labor context

The move to include students with special needs (NEE) in the schools presents a paradigm that raises continual discussion about how to implement this proposal. Considering that learning is built from the weaving of socially constructed knowledge and the field of knowledge concerning subjectivity, this research explores the difficulties that occur with the later in the process of inclusion in the schools. Admittedly, the promise implicit in the school does not guarantee that the student learn, but the envisioning of this learning, when the student s educator discredits him, is such that the person is then not taken on as an actual student, being excluded from the transmission of knowledge, even within the school. The project implemented at the Instituto Educacional Casa Escola IECE, for the last three years, shows us that the possibility and sustainability of this envisioning is intimately linked to the subjectivity of the educator, as well as how one relates to the institutional culture. We question then, how this perspective is formed in the educator this perspective capable of denying the offer of a place as student, allowing him to advance while learning. With this in mind, we explore the paradoxical elements present in the paradigm of inclusion, as well as analyzing theoretically, through the body of conceptual psychoanalysis, the process of subjective constitution. We intend to bring to light how this process coincides with the construction of the educator s perspective of exemption from teaching the special needs students. We question, through the formative functions of subjective structuring (The Mirror Stage and the Oedipus Complex), how to form a perspective capable of promoting inclusion of special needs students in educators. Finally, we show how it is possible to bring to light, with the concepts of the I ideal and the ideal I, the subjective difficulties in the practicing instructor

Educational games can work as a complementary tool in teaching and learning chemistry, playing an important role in the development of the students cognitive structures, familiarizing them with certain conceptual content, which may arouse interest in the study of such content. In this work, we made an analysis of organic chemistry textbooks recommended by Programa Nacional do Livro Didático 2012, for high school students in order to verify the existence of methodological proposals using educational games. From this analysis, we proposed an educational game to be developed for students on 3º year of high medium and undergraduate chemistry, that are in 1º semester of the course, which is constituted of a tray and 48 letters, which work various concepts concerning organic functions, such as: structural characteristics, physical properties, chemical and properties diverse of the compounds used for the confection of the letters. The game was applied to a class degree in chemistry, period 2012.1 to a Federal Education of Rio Grande do Norte and a group of students of the 3rd year of the state schools of Rio Grande do Norte, in the period the months of April and May 2012. The analysis of the performance of the game proposed was made using visual observations, photographic records and testimonials of students who participated in the games. The instrument used for the data collection was the student questionnaire, which was similar for both groups, differing only in the amount of questions, because one of them had one more question. During application of the game it was observed that it constitutes a dynamic strategy in the teaching and learning of chemistry concepts, given that students actively participated in the classes as well, demonstrated more motivation in the construction of concepts, furthermore, it was possible to observe evidence of other possibilities of the game. This could be verified through visual observations and testimonials at the end of each game, by reading the answers to the questionnaires

O presente artigo é o resultado de um pensamento filosófico acerca do ensino de filosofia. O principal objetivo de nossa pesquisa foi entender o que faz o filósofo quando seu ofício é ser professor de filosofia. Para tal, utilizamos como referencial teórico-metodológico o pensamento de Foucault para pensar o filósofo-professor de filosofia em seu lócus - ensino de filosofia - enquanto uma ontologia do presente, e o pensamento de Deleuze e Guattari para indicar uma possível maneira de entender esse ofício de professor que acreditamos se dar em um fazer artístico, filosófico e científico.

Este artigo tem por objetivo trazer à luz os meandros e as particularidades do pensamento de Hegel sobre o ensino da filosofia. Embora esta não seja uma questão central em seu pensamento, é possível notar sua preocupação acerca do tema, especificamente nos textos que escreveu durante o período no qual exerceu a função de professor e diretor do ginásio em Nürember. A apresentação que aqui se faz do pensamento de Hegel sobre o ensino da filosofia divide-se em três momentos: no primeiro, são pontuados os conteúdos que ele julga necessários para a formação do pensamento filosófico; no segundo, é apresentada a questão do método e a sua relação com os conteúdos no ensino da filosofia; e finalmente, no terceiro, procura-se entender o papel que o professor exerce nesse ensino.

JUSTIFICATIVA E OBJETIVOS: Com a perspectiva criada por algumas pesquisas de ações diferenciadas da efedrina sobre a função renal, dependendo da dose utilizada, e considerando-se as controvérsias ainda existentes a respeito dos seus efeitos sobre a função renal, esta pesquisa experimental tem como objetivo verificar se doses diferentes de efedrina determinam efeitos hemodinâmicos e renais diferenciados. MÉTODO: em 32 cães anestesiados com pentobarbital sódico (PS), submetidos a preparação cirúrgica, cateterismo, monitorização, expansão do volume do fluido extracelular e respiração controlada, foi estudada a hemodinâmica cardiovascular e renal e a função renal. Os cães foram distribuídos aleatoriamente em quatro grupos: G controle (n = 8), com os cães permanecendo apenas sob o efeito do PS, G ef. 2 µg (n = 8), G ef. 10 µg (n = 8) e G ef. 100 µg (n = 8), com os cães recebendo efedrina nas doses respectivas de 2, 10 e 100 µg.kg-1.min-1. Os atributos cardiovasculares e renais foram estudados em 5 momentos: controle (M1 e M2), durante a infusão de efedrina (M3 e M4) e após a suspensão da infusão de efedrina (M5). RESULTADOS: Não houve diferença significante entre os grupos em relação aos atributos estudados. em G ef. 2 µg houve aumento significante de freqüência cardíaca, fluxo sangüíneo aórtico, débito urinário e excreção fracionária de sódio. em G ef. 10 µg houve aumento apenas da freqüência cardíaca e fração de filtração, enquanto em G ef. 100 µg ocorreu aumento de freqüência cardíaca, pressão arterial média, pressão venosa central, fluxo sangüíneo aórtico e hematócrito; por outro lado, ocorreu diminuição dos fluxos plasmático e sangüíneo renais e aumento da resistência vascular renal. CONCLUSÕES: A efedrina, dependendo da dose utilizada, apresenta ações hemodinâmicas e renais diferenciadas.

The increasingly request for processing power during last years has pushed integrated circuit industry to look for ways of providing even more processing power with less heat dissipation, power consumption, and chip area. This goal has been achieved increasing the circuit clock, but since there are physical limits of this approach a new solution emerged as the multiprocessor system on chip (MPSoC). This approach demands new tools and basic software infrastructure to take advantage of the inherent parallelism of these architectures. The oil exploration industry has one of its firsts activities the project decision on exploring oil fields, those decisions are aided by reservoir simulations demanding high processing power, the MPSoC may offer greater performance if its parallelism can be well used. This work presents a proposal of a micro-kernel operating system and auxiliary libraries aimed to the STORM MPSoC platform analyzing its influence on the problem of reservoir simulation

As ressecções pancreáticas seguidas de anastomoses acompanham-se de altas taxas de morbidade, que incluem: surtos de pancreatite e, principalmente, fístulas digestivas. Nos transplantes pancreáticos a drenagem da parte exócrina do enxerto para o intestino ou para a bexiga, além das peculiaridades técnicas, também não é isenta de diversas complicações. Visando evitar ou atenuar tais conseqüências e simplificar a técnica cirúrgica, têm sido usadas outras abordagens para o tratamento ductal do coto/enxerto pancreático, tais como: drenagem livre de secreções para o peritônio, com o ducto pancreático aberto, ligadura ductal e oclusão do ducto com polímeros sintéticos. OBJETIVO: O presente estudo visa avaliar clínica e laboratorialmente as funções endócrina e exócrina do pâncreas de coelhos com o ducto aberto e ligado. MÉTODOS: Foram realizadas 150 operações, divididas em 3 grupos: N - manipulação/controle (n=50), A - grupo aberto (n=50), e L - ligado (n=50). Os momentos de observação foram pré-operatório, dia 0 (dia da operação) e pós-operatório (observação e sacrifício): 7 dias, 14 dias, 28 dias, 90 dias e 180 dias. Os parâmetros analisados foram: estado geral, atividade, controles do peso corporal, ingestão hídrica, ingestão alimentar e dosagens da amilase sangüínea, glicemia, glicose urinária e insulina plasmática. RESULTADOS: Todos os grupos tiveram evolução clínica similar, com bom estado geral, ganho ponderal progressivo e valores normais da ingestão hídrica e ingestão alimentar. Exceto uma significativa elevação da amilase sangüínea nas primeiras 24-48h para os 2 grupos com interferência ductal, não houve qualquer alteração dos níveis basais da glicemia, glicosúria e insulinemia entre os 3 grupos experimentais, em todos os momentos de observação. CONCLUSÃO: À exceção da amilase sangüínea, cujos níveis basais foram significativamente elevados no 1º e 2º dias de pós-operatório, as duas modalidades técnicas de abordagem da secreção exócrina do pâncreas, utilizadas em coelhos, não determinaram quaisquer alterações clínicas, bem como dos níveis basais de glicose sangüínea, glicose urinária e insulina plasmática, durante 6 meses de seguimento.

O presente projeto tem como objeto de investigação as experiências do movimento como referências para a formação do professor de dança. Compreende-se a experiência a partir da fenomenologia de Merleau-Ponty, como modo de ser no mundo e delimitam-se para a investigação as experiências relacionadas à cultura de movimento, em geral, e a dança, em particular. Interessa questionar como o movimento mobiliza o sujeito e interfere em sua formação como professor de dança. Do ponto de vista metodológico a pesquisa orienta-se pela Fenomenologia, com enfoque na produção de narrativas escritas do próprio pesquisador e outros professores artistas da cidade de Natal-RN-Brasil. Nesse sentido, espera-se que a investigação seja capaz de apontar perspectivas para a formação do professor de dança que parta primeiramente de sua própria experiência como ser dançante, dinâmica essa necessária à vinculação do professor a área de conhecimento que exerce a docência
