Considering aspects of international literature in the area of Information Science (IS) regarding need, search, behavior and use of information, this study aims to explore the historical path and interpretations of the concepts of user and use of information, under the support reference of the notions of information system and subject agency. For such, a corpus was formed with 15 literature reviews of the Annual Review of Information Science and Technology - ARIST - which brought a theoretical panorama on the concepts here studied. The analysis of these reviews was tooled with categorizations of the use of information proposed by Rachel Anne Fleming-May, making it possible to situate two initial phases identified, particularized for orbiting a notion of information system, being the first phase characterized by a more static conception of system and the second by a more dynamic meaning. Finally, a third and last phase was found in reading ARIST, which was better visualized after the year 2000. In the first decade of the 21st century, studies started considering, complementarily to previous phases, the agency of subjects from the notions of interaction and context, in actions of use, production and appropriation of information and knowledge.

OBJETIVO: Avaliar a evolução metodológica e do delineamento estatístico nas publicações da Revista Brasileira de Ginecologia e Obstetrícia (RBGO) a partir da resolução 196/96. MÉTODOS: Uma revisão de 133 artigos publicados nos anos de 1999 (65) e 2009 (68) foi realizada por dois revisores independentes com formação em epidemiologia clínica e metodologia da pesquisa científica. Foram incluídos todos os artigos clínicos originais, séries e relatos de casos, sendo excluídos os editoriais, as cartas ao editor, os artigos de revisão sistemática, os trabalhos experimentais, artigos de opinião, além dos resumos de teses e dissertações. Características relacionadas com a qualidade metodológica dos estudos foram analisadas por artigo, por meio de check-list que avaliou dois critérios: aspectos metodológicos e procedimentos estatísticos. Utilizou-se a estatística descritiva e o teste do χ2 para comparação entre os anos. RESULTADOS: Observa-se que houve diferença entre os anos de 1999 e 2009 no tocante ao desenho dos estudos e ao delineamento estatístico, demonstrando maior rigor nos respectivos procedimentos com o uso de testes mais robustos, relativamente, entre os anos de 1999 e 2009. CONCLUSÕES: Na RBGO, observou-se evolução metodológica dos artigos publicados entre os anos de 1999 e 2009 e aprofundamento nas análises estatísticas com o uso de testes mais sofisticados, como o uso mais frequente das análises de regressão e da análise multinível, que são técnicas primordiais na produção do conhecimento e planejamento de intervenções em saúde. Isso pode resultar em menos erros de interpretações.

Introduction: This paper presents preliminary results of the research project "Information access: actions and strategies of the Chamber of Deputies to meet 12.527/2011 Law”. Finally some considerations about the implementation of the Law within the Chamber of Deputies are presented. Objectives: Discuss the matter of public information access after the new Brazilian information access law and his relationship between the theories information policy, information regime and informational state. Methodology: Bibliographic research about several theoretical topics related to information access were raised, for example: the concept of information, information policy, informational state, information regime, electronic government and information asymmetry. Results: The preliminaries data shows a convergence of information policies from many countries, for example, Finland, Canada and South Africa, to a same point, which indicates an increase of transparency and a bigger active disclosure of information public. Conclusion: In Brazilian case, in the relationship between State and citizen, the new information access law means a materialization paradigm change or the concretization de other information regime. The sanction of this law can be interpreted as another step to increase the transparency and the affirmation of democratic relationship between State and society.

The objective of this work is to analyze teaching situations with the use of calculator inside classroom aiming to understand its function and potential to the learning of Mathematics. A survey was carried out about the students and teachers’ conceptions concerning the use of calculator as an auxiliary tool in the learning of Math . The first part of the research is based by means of official documents (Parâmetros Curriculares Nacionais (PCN) , Proposta Curricular do Estado de São Paulo, Guia do Programa Nacional do Livro Didático (PNLD)) , researches and other publications , characterizing by a bibliographic study. The survey with the participants— Math students and teachers acting in public or private schools of São Paulo state— was done through a questionnaire and interviews . The results show that most part of interviewed people are in favor of the use of calculator in the classroom . However , a big part of this number still consider it only as a tool to speed calculations with high numbers or decimals . It was verified that teachers who have recently graduated and have taught for a short period of time accept and comprehend the role of calculator more easily in some activities and consider it as an useful and auxiliary tool to the students’ learning
