Guilherme de La Penha: uma história do seu itinerário intelectual em três dimensões

This study focuses on the central Brazilian historiography of science, focusing specifically on the life and work of a contemporaneous mathematician-physicist, and becomes part of the set of research results that investigate, organize and describe personal, intellectual and professional itineraries of Brazilian scientists and educators. The theme chosen for the study ran from seminars on Mathematics in Pará and is up to organize and describe the life history, education, professional experience and scientific production of William Mauricio Souza Marcos de La Penha (Guilherme de La Penha), considering their academic, professional and intellectual life history, so that their academic and intellectual production be spread over the Brazilian scientific and academic community. We adopted the historical research as theoretical and methodological base for the development of this study, rising arguments about the profile of Guilherme de La Penha to characterize him as a multiskill intellectual and to reveal that his thoughts about science, technology, training scientists and educators were in accordance with their writings and their professional practice in order to build a first story about the life and work of William de La Penha. In this sense, we took the theoretical aspects related to historical research, biographies, intellectual itineraries, files and inventories as sources and historical construction vehicles in order to point out the essential elements to form a profile of the transdisciplinary intellectual historians, ie a profile scientist who carries out the research, management and administration, as well as a committed educator to the on-going training and forming process. The results pointed in different directions, among which we highlight the creation of Seção Guilherme de La Penha at Universidade da Amazonia, producing several articles about the life and work of William de La Penha presented at national and international conferences and the proposal for documentary displays which could contribute to understanding the implementation of a scientific area in Pará State, an area that would not only be restricted to the production of knowledge, but more than that, it would include the spreading, which provides various means, primarily through education. Thus it was possible to ensure that La Penha has an intellectual profile that can be considered a multi-and transdisciplinary intellectual who defends the possibility of forming a scientist one and multiple, non-linear attitudes and dialogues with all other areas in order to be understood under a model scientist for the twenty-first century based on the model clearly inspired by the scientist authors with which he identified throughout their training and professional activities, like the three that stood out in their relationship science: Archimedes, Leonhard Euler and Cliford Ambrose Truesdell

A configuração da educação física no Instituto Federal de Educação, Ciencia e Tecnologia do Rio Grande do Norte IFRN: contexto e perspectivas atuais.

Over time the Physical Education on IFRN has considered the sport as the only possibility of pedagogical action. In the purpose of investigating the aspects that determine this condition, this study aimed the context of physical education within the institutional framework and its current perspectives in the process of institutional transformation. In this sense, were addressed the following study questions: What political pedagogical aspects that influenced the context of Physical Education on IFRN and how the pedagogical experience on Mossoro s campus incorporated the perspectives of curricular proposals transformation for the High School and the theoretical changes of the Brazilian Physical Education. Methodologically the work was based on a qualitative approach characterized as a descriptive- comparative research. The technique of discourse analysis was employed in the speech of research collaborators having as categories of analysis the professional activities time in the institution; The ratio of official use of the assumptions to the pedagogical practice of Physical Education in IFRN; The sport in the education process of students and The Prospects of Physical Education in the current configuration of IFRN. The data analysis allowed us to infer that the theoretical methodology of pedagogical practice of Physical Education in IFRN need to be reformulated and that it is necessary a contextualization with the curricular principles of the political institutional pedagogical project and with the Curriculum Guidelines for Secondary Education. The teaching experience developed in the Mossoro s Campus was contextualized with the national curriculum guidelines for secondary education and the theoretical changes of the Brazilian Physical Education. We conclude that it is necessary a collective action of the group of teachers to transform the educational profile of Physical Education of IFRN, beyond the institutional support to be able to consolidate the physical education curriculum component in the current dimensions of society, human being, education, science, technology and work, proposed by the philosophical principles and epistemological political project of IFRN educational

Identificação de crianças e adolescentes com suspeita de câncer: uma proposta de intervenção

Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte

O processo de constituição histórica das diretrizes curriculares na formação de professores de Educação Física

Os processos históricos que permeiam as diretrizes curriculares possibilitaram enxergar quais são as idéias e as preocupações para com a formação de professores no âmbito da Educação Física. Dentro desse contexto, o objetivo foi averiguar, nas políticas públicas de formação de professor dessa disciplina, como ocorreu o processo de qualificação e certificação, buscando entender as justificativas que orientaram a regulamentação dos normativos legais de 1939 a 2004. Portanto, trata-se de um estudo descritivo, de análise qualitativa, tendo como fonte primária as Diretrizes Curriculares veiculada pela imprensa oficial. As novas Diretrizes Curriculares (Resoluções CNE/CP 01/2002, 02/2002 e 7/2004) apontaram perspectivas na formação de um professor mais qualificado para o seu campo de atuação, priorizando a questão da dimensão política da profissão, das competências e do corpo de conhecimento da área. Embora haja progressos em relação aos normativos anteriores, chama-se atenção para a necessidade de que as propostas em construção façam a mediação entre a proposta atual, o percurso histórico do próprio curso e a relação teoria-prática, visando o equilíbrio na formação. A proposta das novas diretrizes não deixa de evidenciar avanços significativos no horizonte da profissionalidade docente e da identidade profissional docente. da mesma forma, para o leitor ou estudioso atento, não deixa de causar preocupação o excesso de competências técnicas colocadas, passando-se a impressão de que agora o que vale é o primado do saber fazer.

Projeto pedagógico: abordagens e implicações no âmbito da formação em odontologia

Proposals that aim a redirection of current health attention models in Brazil are indispensible due to the need of health issues and its challenges imposed by society. These issues come forth in Higher Education Institutions in an attempt to devise ways to face these demands. The research aims to analyze the Pedagogical Project (PP) present in the Dentistry Graduation Course in the Federal University of Rio Grande do Norte in Brazil-(UFRN). This is done in coherence the Brazilian National Curricular Guidelines considering main competences established in the PP. This research was approved by the Ethics Committee at UFRN under document number 285/201. The work is of descriptive nature and was realized with 30 students in the Dentistry Graduation Course. Interviews were realized with the use of problem situation approach. The research was also supported by documental studies that dealt with syllabus present in the disciplines taught at UFRN. Data were processed with the use of the ALCESTE 4.9 software. It is possible to acknowledge that some conservative conceptions arise, even though there is use of active methodologies and innovation that aim to promote reflection and articulation for general competence development such as proposed in the Pedagogical Project in Dentistry Graduation Course at UFRN. These conceptions are mainly present in the teaching-learning process where students do not have full participation. Thus it is possible to conclude that even though there are advances and breakthroughs. This is seen with that fact that there was inclusion of multidisciplinary clinical work as well optional courses in the curriculum. It was also seen that there was occasional use of active teaching methodologies in Dentistry at UFRN. But there is still a need for a didactical and methodological resizing. These actions require the need for progressive development of competences and abilities during the formative process according to what was established in the Brazilian National Curricular Guidelines

Textura do recurso pedagógico e implicações em atividade de encaixe realizada por indivíduos com paralisia cerebral

O estudo teve o propósito de verificar a influência da textura do recurso pedagógico no tempo despendido e no índice de retidão para execução de uma atividade de encaixe realizada por indivíduos com paralisia cerebral. Participaram do estudo 6 alunos com sequelas de paralisia cerebral do tipo espástica, com idade entre 7 anos e 8 meses e 28 anos e 1 mês. O participante deveria segurar o objeto e levá-lo a um ponto demarcado previamente para o encaixe e, após, retorná-lo à posição inicial. O objeto foi apresentado nas texturas lisa, intermediária e áspera, de forma aleatória. Para a coleta de dados, foi utilizada filmagem para posterior leitura pelo programa Kavideo, que possibilitou cálculos para observar o tempo despendido na tarefa e o índice de retidão. Foi realizado o estudo da normalidade das distribuições, verificada por meio do teste de normalidade de Kolmogorov-Smirnov (Teste KS) e a comparação entre as texturas lisa, intermediária e áspera, no movimento de encaixe, por meio da análise de variância de medidas repetidas. Adotou-se para todos os testes nível de significância de 5% de probabilidade para a rejeição da hipótese de normalidade. O resultado do teste de análise de variância de medidas repetidas mostrou que não houve significância para as variáveis estudadas com o recurso apresentado nas três texturas. Porém, os dados da estatística descritiva mostraram que o encaixe do recurso com a textura lisa despendeu um menor tempo para execução da tarefa e, também, determinou um melhor desempenho com relação à trajetória do movimento.

Currículo e deficiência: análise de publicações brasileiras no cenário da educação inclusiva

A educação inclusiva envolve dimensões político-administrativas e pedagógicas. O currículo é umas dessas dimensões, e as adequações curriculares aparecem como uma estratégia para que sejam atendidos os princípios de uma escola para todos. Este estudo objetiva caracterizar o campo de estudos da educação inclusiva, por meio de uma revisão da literatura publicada entre os anos 2000 e 2010, em periódicos da área de educação, disponíveis no banco de dados Scielo. As palavras-chave utilizadas foram curricular, currículo, deficiência, educação especial e necessidades especiais. Os resultados demonstram que as produções na área são escassas no que diz respeito às estratégias para efetivação da educação inclusiva, limitando-se, prioritariamente, a reflexões e discussões teóricas que envolvem os princípios e políticas educacionais, pouco retratando experiências didático-pedagógicas que promovam ajustes curriculares e/ou formas de flexibilização do ensino.

Teoria da Formação e Avaliação no currículo de Educação Física

Having as reference the curricular proposals that composed the new directives for Formation of Professors for the Basic Education, Full Licence in Brazil, it was aimed to analyze in the pedagogic project of a Physical Education Licence course, the professional profile proposed, the conceptual orientation adopted (curriculum model) as well the evaluation proposed in the curriculum. These results obtained from the descriptive study have contemplated documental source and content analysis approach, utilizing as basis for discussion of the results the formation theory. Among the most significant data it was established that, the presented professor profile must consider an Academic, Technological, Practical and Socio-Reconstructionist orientation, detaching during the evaluation process a high skill level in Academic Orientation, as well remarking that the evaluation is presented as a great gap in the pedagogic project.

Forma/ação do professor de Matemática e suas concepções de mundo e de conhecimento

Esta pesquisa busca trabalhar com diferentes concepções de mundo e de conhecimento, investigando a articulação entre o sentido que elas possuem para os professores de Matemática e suas concepções de ensino e de Educação. O estudo gira em torno de discussões que ocorreram em um curso de extensão para professores de Matemática. Esse curso tratou de concepções de mundo e de conhecimento, relacionando-as com diferentes regiões do saber, como Matemática, Física, Ecologia e Artes, focando a transição entre a concepção de mundo da Época Moderna para a concepção de mundo que vem se construindo na denominada Época Pós-moderna ou Contemporânea. A meta é compreender o sentido que aquelas concepções têm para os professores e destacar possíveis momentos de metacompreensão sobre a articulação entre essas concepções e sua prática docente. A metodologia utilizada é qualitativa, de uma perspectiva fenomenológica.

Blood glucose responses in humans mirror lactate responses for individual anaerobic threshold and for lactate minimum in track tests

The equilibrium point between blood lactate production and removal (La-min(-)) and the individual anaerobic threshold (IAT) protocols have been used to evaluate exercise. During progressive exercise, blood lactate [La-](b), catecholamine and cortisol concentrations, show exponential increases at upper anaerobic threshold intensities. Since these hormones enhance blood glucose concentrations [Glc](b), this study investigated the [Glc] and [La-](b) responses during incremental tests and the possibility of considering the individual glucose threshold (IGT) and glucose minimum;(Glc(min)) in addition to IAT and La-min(-) in evaluating exercise. A group of 15 male endurance runners ran in four tests on the track 3000 m run (v(3km)); IAT and IGT- 8 x 800 m runs at velocities between 84% and 102% of v(3km); La-min(-) and Glc(min) - after lactic acidosis induced by a 500-m sprint, the subjects ran 8 x 800 m at intensities between 87% and 97% of v(3km); endurance test (ET)- 30 min at the velocity of IAT. Capillary blood (25 mu l) was collected for [La-](b) and [Glc](b) measurements. The TAT and IGT were determined by [La-](b) and [Glc](b) kinetics during the second test. The La-min(-) and Glc(min) were determined considering the lowest [La-] and [Glc](b) during the third test. No differences were observed (P < 0.05) and high correlations were obtained between the velocities at IAT [283 (SD 19) and IGT 281 (SD 21)m. min(-1); r = 0.096; P < 0.001] and between La,, [285 (SD 21)] and Glc(min) [287 (SD 20) m. min(-1) = 0.77; P < 0.05]. During ET, the [La-](b) reached 5.0 (SD 1.1) and 5.3 (SD 1.0) mmol 1(-1) at 20 and 30 min, respectively (P > 0.05). We concluded that for these subjects it was possible to evaluate the aerobic capacity by IGT and Glc(min), as well as by IAT and La-min(-).

A Non-Destructive Testing Based on Electromagnetic Measurements and Neural Networks for the Inspection of Concrete Structures

This paper presents a new non-destructive testing (NDT) for reinforced concrete structures, in order to identify the components of their reinforcement. A time varying electromagnetic field is generated close to the structure by electromagnetic devices specially designed for this purpose. The presence of ferromagnetic materials (the steel bars of the reinforcement) immersed in the concrete disturbs the magnetic field at the surface of the structure. These field alterations are detected by sensors coils placed on the concrete surface. Variations in position and cross section (the size) of steel bars immersed in concrete originate slightly different values for the induced voltages at the coils.. The values for the induced voltages were obtained in laboratory tests, and multi-layer perceptron artificial neural networks with Levemberg-Marquardt training algorithm were used to identify the location and size of the bar. Preliminary results can be considered very good.

Princípios éticos na experimentação animal

The treatment of animals used in research or in education tests requires proper care, scientific judgment and qualified professionals to understand the needs of the animals and the special requirements of the research, tests, and educational programs. The established guidelines aim the development of knowledge necessary for the improvement of health and wellbeing of humans as well as animals to get precise and accurate results. The techniques should not be performed with inappropriate procedures that cause pain or suffering. Some principles should be considered to have an appropriate animal care and treatment.
