O ensino médio no contexto do Plano Nacional de Educação: o que ainda precisa ser feito

A intenção desse artigo é analisar alguns objetivos e metas propostos para o ensino médio, pelo antigo Plano Nacional de Educação (pne Lei n. 10.172/01), no sentido de avaliar quais deles foram totalmente alcançados, quais foram parcialmente alcançados e quais não foram atingidos, visto que um novo pne está sendo proposto. Por outro lado, nosso objetivo também é avaliar em que medida o alcance ou não das metas propostas no início da década passada influencia na percepção e nas expectativas dos alunos do ensino médio em relação ao seu ingresso, num futuro próximo, no ensino superior. Serão abordadas questões referentes ao atendimento e à oferta de ensino médio e suas questões pedagógicas específicas.

O ensino por problemas nos livros de química: uma análise do conteúdo estrutura atômica

La enseñanza de problemas se ha investigado en la didáctica de las ciencias naturales como un medio importante para desarrollar el aprendizaje de los conocimientos científicos y la formación de competencias básicas. Dada la importancia de los libros de texto para la enseñanza de la ciencia, con el fin de verificar el enfoque de la enseñanza con problemas en los libros de química, se procedió a una investigación realizada en las obras aprobadas en PNLD 2012, basado en el método de Análisis de Contenido. Se analizó el contenido de la estructura atómica, como marco teórico la perspectiva de la enseñanza problémica, basada en el materialismo histórico y dialéctico. Metodológicamente la investigación presenta un carácter cualitativo. Los resultados del análisis de contenido corroboraron la cuestiones de estudio iniciales relacionadas con la explicación centrándose en los problemas, lo que permitió inferir la elaboración de una Unidad Didactica basada en los métodos problémicos para la enseñanza de los modelos atómicos por la exposición problémica, la conversación heurística y la busca parcial, como forma de aproximar los estudiantes a la naturaleza de las ciencias naturales y contribuir al desarrollo de actitudes positivas en el aprendizaje de la química

Sobre o financiamento no Plano de Desenvolvimento da Educação

Este artigo apresenta uma análise inicial do financiamento das ações do Plano de Desenvolvimento da Educação - PDE -, lançado em abril de 2007 pelo governo federal, focalizando algumas expectativas, impasses e impactos. Muitas das inquietações e dúvidas aqui expostas foram manifestadas no Seminário Itinerante O Plano de Desenvolvimento da Educação - PDE - em Debate nas Universidades Públicas Paulistas, em que especialistas de diferentes instituições tiveram a oportunidade de debater com os formuladores e responsáveis pela implementação do plano. Optou-se por organizar análise em três partes. Na primeira parte, discutem-se alguns pressupostos do financiamento da educação nacional, mostrando que o país pode e deve aplicar mais recursos para alcançar um desenvolvimento educacional e social adequado. Na segunda, analisam-se documentos do MEC que explicitam as concepções que fundamentam o PDE no que se refere ao financiamento das 40 ações propostas. Na terceira, os autores se posicionam quanto à forma de financiamento adotada e quanto aos recursos previstos ou alocados para a execução das ações. Para finalizar, uma série de questões sobre o plano são levantadas em perspectiva propositiva.

Procedimentos de abertura e fechamento de tópicos na interação em sala de aula

This study is part of interactional perspective, focusing on Conversation Analysis theories, from the Textual Interactive Perspective and Text Linguistics . This research, from its guiding questions, aims at understanding the interaction between teacher and students in the process of the knowledge construction as well as at describing, analyzing and understanding aspects of topical organization speech in the classroom in elementary school, observing the opening and closing procedures of the speech topics in that particular space. Considering that the procedures for opening and closing of discursive topics occur through language marks, we tried to identify which speech marks are used in the opening and closing of the topics studied in the classroom, in interaction during the collaborative process of the discourse established between teacher and students. Therefore, this study is based on authors who analyze specific questions of the text in real context of language use: Koch (1993, 1999), Jubran et al (1991), Jubran (2006), Pine (2005), Penhavel (2010), Galembeck (2012), Barros (1991), Marcuschi (1986 , 1990, 1991 , 1998 , 1999, 2003 , 2004a), Kerbrat - Orecchioni (2006), Favero (1999, 2002) and Galvão (2004, 2010). As a methodology of investigation, the study is focused on the postulates of ethnographic research in order to carry out data collection, through audio and video recordings which were transcribed, according to the NURC project proposal, with some adaptations. Data analysis showed that the procedures for opening and closing of the speech topics occurred by the use of discourse markers, in particular the marker "then", allowing us to understand that these elements are important in the topical organization speech, contributing to ensure textual cohesion and coherence. We conclude that the organization of the discursive topic in the classroom occurs through events that support the explicitness of the content of teaching and learning, considering the diverse necessity of an institutional academic plan, whose main objective is the construction of knowledge

Plano Nacional de Saúde e o lugar social em disputa

O presente artigo apresenta uma análise do Plano Nacional de Saúde publicado em 2004. Este documento expressa um importante período de transição na gestão do SUS, uma vez que foi predecessor do Pacto pela Saúde. A partir de um estudo descritivo com base em procedimentos quantitativos e qualitativos, o objetivo foi compreender as ideias centrais do documento, identificando as conexões existentes entre seus princípios, objetivos e prioridades. O principal resultado do estudo foi a identificação da integralidade das ações, da capacitação dos recursos humanos e mudança do marco regulatório com base numa visão intersetorial como núcleo central do documento. Essas ideias, por sua vez, circulam pelo discurso das diretrizes do plano, fortalecendo os laços do eixo central do texto na reorganização da atenção ambulatorial e na qualificação profissional. Por fim, quando comparadas metas e ações previstas nas diretrizes, observa-se uma tensão entre o que foram denominados vetores da verticalidade e da horizontalidade, deixando em aberto o rumo do lugar social em disputa.

O Planejamento estratégico sem plano: ícones urbanos e dinâmica imobiliária em Natal

The model of strategic city planning is applied to Latin American and Brazilian cities since the 1990s. Notwithstanding, in many cities, the production of space has not followed the international model stricto sensu, but a variation of the model, here called, strategic city planning without a plan or peripheral (or yet incomplete) urban entrepreneurialism . This seeks to build city attributes in order to qualify cities for the competitive international and/or regional markets. This includes the production of iconic buildings and structures, here called urban icons. They rapidly become symbols in the contemporary city landscape, facilitating the promotions of the city for tourism and business. This also helps produce charismatic leaderships. However, what it does best is to promote real estate development. This dissertation seeks to understand the role of iconic buildings in the promotion of real estate business in Natal, especially how it helps to fuel prices in the market. The research is done by use of interviews with civil servants and private entrepreneurs related to real estate business

Análise de células t regulatórias foxp3+no líquen plano oral

T regulatory cells have the function of controlling immune responses and maintaining self-tolerance. The FoxP3 has been considered the most specific marker for Treg cells. The aiming of this paper was to evaluate the immunoexpression of FoxP3 in the inflammatory infiltrate from oral lichen planus (OLP) and to compare it with the infiltrate in fibrous inflammatory hyperplasia (FIH) and then, between reticular and erosive forms of OLP. The samples were composed by 32 cases of OLP (17 reticular and 15 erosive) beyond 10 cases of FIH that were submitted to immunohistochemistry staining for FoxP3. Localization of the staining was classified in underepithelial and intraepithelial and the amount of FoxP3+ cells was evaluated through cells counting in 10 consecutive fields, at 400x power magnification. The values were expressed in mean ± standart deviation, and submitted to statistical tests with 5% of significance level. It was observed a statistical significant difference in the amount of FoxP3+ Treg cells between the two combined forms of OLP (1,6 ± 2,2) and the FIH (0,5 ±0,4) (P<0,05). This maybe could be explained by immunological mechanism of OLP, which involves a permanent antigenic induction likely with consequent perpetuation of lesion, eliciting the proliferation and constant recruitment of Treg cells. Otherwise, FIH presents a different etiopathogenesis, in which there is also generation of a variable inflammatory infiltrate, however qualitatively distinct from that seen in OLP. The erosive form of OLP exhibited a greater number (1,7 ± 2,4) of FoxP3+ Treg cells than reticular form (1,5 ± 2,1). These alterations could have relation with the great disease activity verified in erosive OLP, or also, with abnormalities in the regulatory function of Treg cells that could cause the increase observed. Considering the capacity already well established in the literature, both about Treg cells in modulating immune responses, as in the oral mucosa in showing great potential for regeneration, it is suggested that the possibility of development and implantation of immunotherapeutic strategies that regulate the frequency and function of these cells, may help in future treatment of immune-mediated inflammatory diseases such as OLP

Estudo clínico e níveis de ansiedade em uma série de casos de líquen plano oral

Oral Lichen Planus (OLP) is a relatively common, cronic inflammatory disease. Its etiopathogenesis is no completely understood and several factors have proposed in attempt to explain the appearance, variety of clinical manifestations and periods of exacerbation and remission of the symptons of the lesions. The objective of the present study was to assess the presence of local factors, systemic diseases and levels of anxiety in patients with OLP, investigating their association with the clinical characteristics of the lesions. The sample consisted of 37 patients with histopathologically confirmed OLP that were submitted to a clinical exam to evaluate the presence of smoking habits, consumption of alcoholic beverages, diabetes mellitus, hypertension and hepatitis C virus (HCV) infection. The existence of skin lesions, as well as the time course, clinical form, symptomatology, number and location of the oral lesions were also registered. The trait anxiety was measured by Spielberger s Stai-Trait Anxiety Inventory (STAI), and to associate the variables we used the chi-square or Fisher s exact test. It was observed that females were the most affected (75%) and the mean age of the patients was 53,3 years. Most cases were non-smoker (97,3%) and none was drinker. Diabetes mellitus and hypertension were present in 10,8% e 16,2% of the sample, respectively and only one patient was HCV-seropositive (2,7%). Moderate levels of anxiety were seen in most cases (78,4%) and 21,6% had elevated levels. The oral lesions persisted in 95% of the cases for a period of 6 months to 13 years. The erosive form was the most prevalent (57,1%) and symptons were reported by 45,7% of the patients. Multiple lesions were frequent (60%), affecting mainly the buccal mucosa, followed by gums e tongue. There was no significant association of the presence of diabetes mellitus, hypertension and levels of anxiety with the clinical form or symptomatology of the oral lesions (p>0,005), despite a trend in patients with hypertension to have erosive lesions. It was concluded that, in the sample studied, moderate levels of anxiety were commonly observed, and the HCV infection apparently is not related to the onset of the OLP. In this study, the presence of diabetes mellitus, hypertension and levels of anxiety seem not to be associated with the clinical characteristics of the lesions of OLP

Análise da resposta th17 em líquen plano oral

Th17 cells have been strongly associated with the pathogenesis of several autoimmune and inflammatory diseases. IL-17 and IL-23 are important cytokines associated with this lineage. The aim of this study was to analyze, through immunohistochemical methods, the immunoexpression of IL-17 and IL-23 in the inflammatory infiltrate of oral lichen planus (OLP) lesion compared to that of inflammatory fibrous hyperplasia (IFH) and between clinical forms reticular and erosive of OLP. The sample included 41 cases of OLP, of which 23 were reticular and 18 erosive and 10 cases of IFH. The results were subjected to nonparametric statistical tests with a 5% significance level. In OLP lesions histomorphological analysis, the most common findings were: hyperparakeratinization, specimens with atrophic epithelium in erosive clinical form (p = 0.011), epithelial projections in most of reticular type of lesions, in addition Civatte bodies were identified in most samples of both clinical forms. For immunohistochemistry analysis, five fields with strong immunoreactivity for IL-17 and IL-23 were photomicrographed at 400x magnification, images were transferred to a computer where with ImageJ software®, lymphocytes that exhibited cytoplasmic immunostaining for these cytokines were counted. A mean was established after for each case. There was no statistically significant difference in the number of imunopositive lymphocytes for IL-17 and IL-23 among the group of OLP and IFH group, however a larger amount of lymphocytes imunopositive for IL-17 was found in the LPO group (p = 0.079) and significantly higher amounts of those lymphocytes were found in the erosive OLP when compared to the group of reticular OLP and IFH (p = 0.019). Furthermore, a marker epithelial immunopositivity for IL-17 was observed in OLP group. Although the results of this study do not permit the forceful assertion about the participation of Th17 lineage in OLP lesions, the findings of immunopositive lymphocytes counting for IL-17 and IL-23, which are potent proinflammatory cytokines, together with the the marked epithelial immunopositivity found for IL-17 in this study, suggest a possible role of this lineage in the pathogenesis of this disorder

Avaliação da angiogênese em lesões de líquen plano oral e pênfigo vulgar

Oral lichen planus and pemphigus vulgaris are chronic diseases mucous membrane immune of unknown aetiology that can be observed affecting to the oral mucous. A relevant as regards neoplasies the role angiogenesis in the inflammatory chronic disease pathogenesis as it provides a substancial interest can be considered as being an activity diseases marker; besides being through specialised research of this angiogenic process to improve of understanding pathogenic mechanism. This research proposes to assess angiogenic active through of antibody immunohistochemistry expression antiCD34 antibody in 26 OLP of reticular cases, 14 OLP erosives cases, 18 of PV cases and 15 specimens of normal oral mucosa. The result was submitted non-parametric tests of 5% significance level. It is not statistically significant correlacion was seen regarding between average vessels. However, only be effectively observed the median of OLP cases was larger than pemphigus vulgaris in fact proved average larger than oral normal mucosa (p=0,280). Regarding the microvascular count of CD34 concerning clinic form oral lichen planus (reticular and erosion) increased emphasis is more cross-border average for the form erosion clinic. Despite of the statistic tests could not be more effective (p=0,720). Even though, the results of the research is not sufficient to enable to consider of angiogenic process in the pathogenesis and lesions progression of oral lichen planus and pemphigus vulgaris, we suggest this process is present in both forms lesion, however, more studies must be made in the near future in order to prepare a well-founded proposal

Investigação da relação entre conteúdo onírico e aprendizado de uma tarefa cognitiva complexa

Several lines of evidence indicate that sleep is beneficial for learning, but there is no experimental evidence yet that the content of dreams is adaptive, i.e., that dreams help the dreamer to cope with challenges of the following day. Our aim here is to investigate the role of dreams in the acquisition of a complex cognitive task. We investigated electroencephalographic recordings and dream reports of adult subjects exposed to a computer game comprising perceptual, motor, spatial, emotional and higher-level cognitive aspects (Doom). Subjects slept two nights in the sleep laboratory, a completely dark room with a comfortable bed and controlled temperature. Electroencephalographic recordings with 28 channels were continuously performed throughout the experiment to identify episodes of rapid-eye-movement (REM) sleep. Behaviors were continuously recorded in audio and video with an infrared camera. Dream reports were collected upon forced awakening from late REM sleep, and again in the morning after spontaneous awakening. On day 1, subjects were habituated to the sleep laboratory, no computer game was played, and negative controls for gamerelated dream reports were collected. On day 2, subjects played the computer game before and after sleep. Each game session lasted for an hour, and sleep for 7-9 hours. 9 different measures of performance indicated significant improve overnight. 81% of the subjects experienced intrusion of elements of the game into their dreams, including potentially adaptative strategies (insights). There was a linear correlation between performance and dream intrusion as well as for game improval and quantity of reported dreaming. In the electrophysiological analysis we mapped the subjects brain activities in different stages (SWS 1, REM 1, SWS 2, REM 2, Game 1 and Game 2), and found a modest reverberation in motor areas related to the joystick control during the sleep. When separated by gender, we found a significant difference on female subjects in the channels that indicate motor learning. Analysis of dream reports showed that the amount of gamerelated elements in dreams correlated with performance gains according to an inverted-U function analogous to the Yerkes-Dodson law that governs the relationship between arousal and learning. The results indicate that dreaming is an adaptive behavior

Será que o conteúdo científico contido nesse material é, realmente, aproveitável? O discurso utilizado pelos jornalistas promove o conhecimento científico sobre os assuntos que discutem? Assim, este trabalho teve por objetivo analisar, quanto ao conteúdo científico, didático e acessível, matérias das revistas semanais de conteúdo geral mais lidas do país, Veja e Época, publicadas em 2008, com o tema Meio Ambiente. Os resultados permitiram concluir que os textos apresentados pela revista Veja promovem um discurso científico aproveitável do ponto de vista didático, podendo ser utilizados em sala de aula como material de apoio e complementar pelos professores.

O psicólogo e os serviços de acolhimento institucional para crianças e adolescentes

The Shelters are responsible for caring for children and adolescents whose families or guardians are temporarily unable to fulfill his role as care and protection. The activities to be developed by psychologists in these services are greatly important for the elaboration and development of political- pedagogical project of the same, and for reasons pertaining to the present and future of children and adolescents received judgments. The psychologist puts up the challenge of contributing to a better care of children, also cooperating with the implementation of the new care standards of childcare. The aim of this study was to investigate the role of the professional psychologist in assistance to children and adolescents in 13 Shelters in the Metropolitan Region of Natal/RN. For both set out to make visits to the institutions to know how it is organized the field work of the psychologist, his routine work and activities developed. Nine psychologists interviewed according to a semi-structured interview script. The data analysis is supported by the theoretical aspects of dialectical materialism historical and theme content analysis was used. Results were presented from three angles: psychologists and institutional framework; activities, resources and methods of work; psychologists and legal frameworks of the Institutional Hospitality. The study points out the recent entry of the psychologist in Shelters, combined with considerable turnover of these professionals. This work has been organized through the Individualized Service Plan, prioritizing the return to family of origin. Moreover, in general, perform joints with the service network, reporting, individual consultations and follow-adoption processes . Staff members, however, feel a lack of specific and continuing training on special protection, including due to the distance between the proposed theory and practice. It was thus observed a movement of psychologists distance themselves from welfare or repressive practices, however the structural difficulties of services and lack of continuing education appear to limit the development of a performance focused on the transformation of the reality of children and adolescents treated and their families

Aprendizagem na interação ensino-serviço-comunidade: a formação na perspesctiva dialógica com a sociedade

Considerando o papel do ensino superior em saúde para a sociedade brasileira, em que os egressos dos cursos ofertados na área serão os profissionais prestadores de serviços à população, este estudo objetivou analisar o componente ensino do PET-Saúde da Família - Natal-RN na formação de estudantes dos cursos de graduação em saúde da UFRN. Foi realizada pesquisa qualitativa com análise de documentos das disciplinas SACI e POTI datados entre 2009 e 2011 (portfólios, avaliações de desempenho e oficina de avaliação), mediante o auxílio do software Alceste© e análise de conteúdo, segundo Bardin. Na análise foi encontrado como potencialidades: o alunato trabalhando em grupo tutorial multidisciplinar, cuja interação e contato com a Unidade de Saúde da Família, incluídos os profissionais, bem como a comunidade, instiga nos aprendizes o diálogo consigo mesmo e com o outro, numa construção dos ser/agir no mundo. Os textos trabalhados durante as aulas permitem refletir e teorizar a respeito da realidade observada, auxiliando-os na identificação dos problemas e no traçar estratégias de intervenção. Já a observação da realidade reveste o aluno de humanização. Este passa a captar as necessidades e dificuldades enfrentadas pela comunidade observada. Nas fragilidades ficaram evidenciados: problemas de relações interpessoais entre os estudantes da SACI; a maioria dos projetos de intervenção ocorrendo numa perspectiva paternalista, reproduzindo o modelo de prestação de serviços na saúde mais praticado nas sociedades brasileiras; dificuldades em aprofundar no aprendiz, a importância da teorização dos assuntos; problemas de financiamento de projetos de intervenção; descumprimento do plano de ensino em alguns grupos tutoriais; e, por fim, dificuldades dos alunos e monitores em acompanhar as atividade de pesquisa e extensão do PET-Saúde, pela falta de integração dos projetos pedagógicos dos cursos. Conclui-se que o componente ensino do PET-Saúde da Família adota metodologias ativas de ensino na inserção de alunos na Atenção Primária em Saúde, proporcionando uma formação dentro de princípios éticos e humanísticos a partir do trabalho em equipe e da inclusão reflexiva dos alunos na Estratégia Saúde da Família. Apesar da existência de fragilidades concernentes às relações interpessoais, descompasso entre as proposições multiprofissionais e interdisciplinares da SACI e POTI e as dificuldades de pô-las em prática em currículos fragmentados e organizados por disciplinas pouco flexíveis, potencialmente, ao fim dessas experiências conectadas a Atenção Primária, os discentes apresentam uma nova visão do cuidado com a saúde, próxima às necessidades da população, iniciando uma tomada de postura crítica e reflexiva, entendendo-se com sujeitos ativos no construir a saúde coletivamente

A situação atual da indexação nas tarefas bibliotecárias

Na atualidade a atribuição dos descritores de assuntos ou indexação do conteúdo dos livros, nem sempre está associada ao contexto concreto de cada biblioteca, provocando, em muitos casos, que a recuperação por assuntos não resulte adequada. Neste trabalho analisam-se os principais desafios e perspectivas da indexação dos livros, os avanços de análises de assuntos nos catálogos de bibliotecas, examinam-se procedimentos, instrumentos, regras e condutas utilizadas nas análises e representação do conteúdo dos livros. Também se mostra a interação entre o ensino, a pesquisa e a atuação profissional necessária para que os estudantes possam desenvolver competências na análise, na representação e na procura da informação, assim como os princípios - provavelmente menos evidentes- da organização do conhecimento. Este trabalho coloca em evidência que as políticas de gestão da informação, mais quantitativas que qualitativas, deixam num segundo plano o processamento intelectual do conteúdo prejudicando, desta maneira, a recuperação por assuntos através do catalogo da biblioteca. Finalmente, se recolhe uma serie de propostas docentes relacionadas com a atribuição de descritores de assuntos em contextos bibliotecários.
