The information society is increasingly incorporating the immense volume of content available on the net. Access by electronic devices and the resulting ease of mobility and portability feed discussions on actual capacity of appropriation of this knowledge that circulates through cyberspace. Address and discuss the possibilities of educating across the network, therefore, gains more and more importance. On models of educational quality well developed – as is the case in Finland, for example-, Brazilian education is, year after year, failing in international marathons to achieve below average indexes required. Creates a field of analysis, in which this article arises, in the quest to understand more deeply the opportunity of use of Information and communication technologies (ICT) for a quality education, plunging by cultural issues that fall in the construction of objective conditions offered to students. This is an effort in understanding the historical factors that limit efforts to offering a quality education in Brazil.

Na presente publicação apresenta-se análises de um conjunto de manuais escolares que circularam na Escola Normal brasileira e portuguesa entre meados do século XIX e meados do século XX a partir de diferentes olhares, reeditando em outra chave o processo original de circulação de ideias entre Brasil e Portugal no qual esses materiais se inserem. Orientados por outros estudos que tratam do mesmo tema, os autores realizaram recolha nos dois países a fim de comprovar a circulação do corpus empírico que, ao final, foi definido como fonte. Assim, chegou-se ao seguinte conjunto de manuais didáticos: Elementos de Pedagogia de Affreixo & Freire (1870); Curso Prático de Pedagogia Destinado aos Alunos-Mestres das Escolas Normaes Primarias e aos Instituidores em Exercício de Daligault (1874); Lições de Pedagogia Geral e de História da Educação de Pimentel Filho (1875); Lições de Pedologia e Pedagogia Experimental de Faria de Vasconcelos (1910); Lições de Metodologia, de Fonseca Lage (1920); A arte da leitura, de Mário Gonçalves Viana (1949) e Lições de Pedagogia, de Aquiles Archêro Junior (1955). Os pesquisadores utilizam diferentes lentes para tecer suas análises e, cada um segundo sua especialidade de pesquisa, aprofunda aspectos que, juntos, compõem um painel interpretativo sobre o processo de escolarização e seus espaços, a normatização do trabalho docente, os princípios que nortearam a seleção cultural para a escola primária, a constituição de modos e métodos de ensino para realizar os objetivos educacionais e a especificidade que assumem os materiais e o ensino da leitura e da escrita nessa instituição. Todas as análises reiteram a importância dos impressos na consolidação da escola primária portuguesa e brasileira, notadamente no que se refere às prescrições feitas nos manuais escolares que, em trânsito, configuram-se como palavras viajeiras.

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.

A Educação Física sofreu tentativas de mudanças desde surgimento até os dias de hoje, sobretudo no espaço escolar. Podemos observar esse fenômeno desde o final da década de 1980 onde surgiram inúmeras publicações de livros e artigos abordando tal tema, que iam contra uma Educação Física voltada para o militarismo e o tecnicista. Essas ideias atingiram o auge na década de 1990 e ainda estão fortemente presentes e marcadas por debates e defesas de ideias. Essas tentavam explicar o ser humano como um todo em seus diferentes aspectos - cognitivos, sociais, afetivos, motores e culturais, por meio do movimento, pois se sabe que a Educação Física é a área do conhecimento que estuda o se movimentar do ser humano e o diálogo que ele exerce com o mundo. Dessa forma esse trabalho busca analisar os conteúdos das questões do ENEM de 2009, 2010, 2011 e 2012 e identificar quais são as concepções que aparecem nas questões, de modo a compreender o que o Exame acredita ser considerado importante para o aluno aprender na educação física escolar. Para o desenvolvimento desta pesquisa usaremos como material as questões da prova do ENEM de 2009 a 2012 e realizaremos uma análise do conteúdo buscando assim descrever e interpretar o conteúdo das questões selecionadas. Entende - se que a análise do conteúdo baseia-se nas ações de comparação e de classificação textuais, ou seja, no entendimento de semelhanças e diferenças

Studies show that the disciplines of differential and integral calculus have high failure rates in all schools where they are present and, although this problem has been accentuated in recent years, it is not a local phenomenon. It's observed since 1970s in various Institutions of higher education in Brazil. These studies seek to understand the causes of failures and proposals for teaching methodology that aims to help reduce these rates. However, there is a large contingent of students who are successful at the first time that they perform these disciplines. And these cases, although they have not been studied, can contribute greatly to the understanding the aspects that are related to learning of them. And this understanding can lead to attitudes and learning and teaching methodologies that promote the expansion of this success. The fact that these subjects also have high failure rates in the Degree in Chemistry of this Institute, this study aimed to investigate the factors that were relevant to the cases for approval of the students performed for the first time. For this we constructed a questionnaire containing objective questions and open answers. The objective sought to diagnose the profile of these students with regard to age, gender, basic education (elementary and middle school), study habits, concurrent activities, among others. These questions were analyzed using simple statistics. The open-ended questions asked students to indicate that they attribute the success obtained in the disciplines and to suggest modes of study. These questions were analyzed using thematic categorization, a method of content analysis. This questionnaire was completed, voluntarily and without identification, by students who have passed the first time attended the courses Calculus I and/ or Calculus II and had never started another college prior to this. The results indicate that the most relevant factors in this process were dedication and correct habits...

Dental avulsion is the most severe type of traumatic tooth injuries because it causes damageto several structures and results in the complete displacement of the tooth from its socketin the alveolar bone. The ideal situation is to replant an exarticulated tooth immediatelyafter avulsion because the extraoral time is a determinant factor for treatment successand for a good prognosis. However, it is not always possible. The success of replantationdepends on a number of factors that may contribute to accelerate or minimize theoccurrence of root resorption or ankylosis, among which is the type and characteristicsof the medium used for temporary storage during the time elapsed between avulsionand replantation. Maintaining the tooth in an adequate wet medium that can preserve,as longer as possible, the vitality of the periodontal ligament cells that remain on rootsurface is the key to success of replantation. Recent research has led to the developmentof storage media that produce conditions that closely resemble the original socketenvironment, with adequate osmolality (cell pressure), pH, nutritional metabolites andglucose, and thus create the best possible conditions for storage. Although these storagemedia can now be purchased in the form of retail products, the most common scenariois that such a product will not be readily available at the moment of the accident Thispaper reviews the literature on the different storage media that have been investigatedfor avulsed teeth based on full-length papers retrieved from PubMed/Medline, Lilacs, BBOand SciELO electronic databases using the key words storage medium , transportationmedium , avulsion , tooth avulsion , replantation , tooth replantation , milk and propolis .After application of inclusion and exclusion criteria, 39 papers were selected and criticallyreviewed with respect to the characteristics, efficacy and ease of access of the storagemedium.

The root resorption is one of the possible sequels of greater complexity to the orthodontist, the difficulty of detection and be asymptomatic. The presence, during the orthodontic treatment, is linked to a multifactorial origin, a complex combination of biological activities, anatomical, physiological, genetic variables and mechanical forces. Thus, the aim of this study was perform to critical literature review related to root resorption in orthodontic movement. Were included articles published between 2004 to 2014, indexed in the PUBMED database. Used descriptors contained in the Mesh, being adopted as inclusion criteria: clinical trials in humans, only articles that had clear ideas and objective, articles with English language. The search strategy used resulted in 24 articles and after applied the inclusion and exclusion criteria, 11 articles remained. Based on the results of this study it was concluded that heavy forces of intrusion, inclination and torque leads to a greater degree of root resorption; its etiology is multifactorial, the periodic radiographic control during treatment is needed and further studies are suggested to identify more specifically the causes and risk factors for root resorption.

In this paper we present results of research conducted on the constitution of the identity of CEM (Centre for Mathematics Education), a group of mathematics teacher educators from the city of São Paulo, Brazil (1984-1997). We emphasize the processes of constitution of CEM’s identities, on the perspective of Oral History in Mathematics Education, of the Model of Semantic Fields and of theories of identities. As part of the broader endeavor of examining possibilities for constituting identities for the group, from several theoretical standpoints, here we report an exercise on constituting the identity of CEM from a Cartesian standpoint; the overall assumption is that we are not properly interested in what CEM is or was, but on the possibilities themselves. We argue that such analysis leads to an understanding of the group as being an accident involving the individual identities of its members but not to an understanding of CEM’s group identity as such.

Objective and closed questions were applied to 15 - 21 years old individuals under regular resistance exercise practice and self-reported nutritional supplements users, approaching training practices, type of substance feed and socioeconomic characteristics. The data were treated by frequency around the mean value. Major difference was observed to the goal of improvement in physical fitness (Guaruja 21% and Bauru 9.6%), close to the muscle hypertrophic enhancements (Guaruja 22% and Bauru 19.2%), and health proposes (17.3%), which was only reported in the country city. The monthly employment with supplements was observed to be close to one hundred Real, in both regions (Guaruja 79% and Bauru 80%). Even, based on different purposes, the supplements feed practice was closed to the goals, showing a reliable referential of use, but done without appropriated professional care.
