TRICUT: a program to clip triangle meshes using the rapid and triangle libraries and the visualization toolkit

An efficient technique to cut polygonal meshes as a step in the geometric modeling of topographic and geological data has been developed. In boundary represented models of outcropping strata and faulted horizons polygonal meshes often intersect each other. TRICUT determines the line of intersection and re-triangulates the area of contact. Along this line the mesh is split in two or more parts which can be selected for removal. The user interaction takes place in the 3D-model space. The intersection, selection and removal are under graphic control. The visualization of outcropping geological structures in digital terrain models is improved by determining intersections against a slightly shifted terrain model. Thus, the outcrop line becomes a surface which overlaps the terrain in its initial position. The area of this overlapping surface changes with respect to the strike and dip of the structure, the morphology and the offset. Some applications of TRICUT on different real datasets are shown. TRICUT is implemented in C+ + using the Visualization Toolkit in conjunction with the RAPID and TRIANGLE libraries. The program runs under LINUX and UNIX using the MESA OpenGL library. This work gives an example of solving a complex 3D geometric problem by integrating available robust public domain software. (C) 2002 Elsevier B.V. Ltd. All rights reserved.

Bibliotecas escolares e instrumentos digitais nos espaços escolares: uma pesquisa em Marília-SP

The article reports on research conducted with fifteen teachers and forty-five students in three high schools municipal Marília - SP, with the goal of mapping relationships between school libraries, computer labs and digital devices. The investigation is linked to the other two poles: one in the Faculty of Education, Federal University of Uberlândia and another at the French Institute of Education, in Lyon, France. Responses were obtained through questions previously formulated and recorded by scholars in an interview situation. The article initially retrieves historical projects of French in the late nineteenth century with the intention of establishing linkages with the situation in 2012, in Brazil. It then presents and comments on the graphics with data. The findings indicate the absence of organicity in relations between libraries and computer labs. Handheld devices outside of school are predominantly used to play and participate in social networking sites.

Biblioteca escolar: espaço de formação inicial do leitor na educação infantil

The books are part of the school routine in the course of our lives, currently, we are the gateway to the processes of social literacy that begins with the presentation of these objects for babies and children in early childhood education (EI). This research has the main question: to know how are the libraries or reading rooms in Early Childhood Education Centres (CEI) of Botucatu. Thus, the overall goal is to understand, characterize and analyze the CEIs libraries Botucatu. What implies: investigate and analyze the existing legislation on school libraries, their approach to the reality of the CEIs and the official documents of early childhood education; To investigate the relationship between the child and the playful objects (books, toys etc.) and finally discover and describe the reality of School Libraries in CEIs studied. The research is qualitative orientation, more precisely a Case Study. The space, proper equipment and support provide a rich learning that will serve as the basis for school achievements. However, the offering of School Libraries and Reading Rooms in many cases it is not a reality. The survey took into account which of the schools have assets, how is the organization of space, the playful activities with learners users and which functions, training and professional responsibilities designated as responsible for School Library/Reading Room. It is noteworthy to say the official documents as a basis and motive of this research as well as the fulfillment of established targets and carried out by the municipal, state and national governments on the implementation of School Libraries in schools, with the help of programs like National Fund Development of Education (ENDF), National School Library program (PNBE) and the National Book and Reading Plan (PNLL)

New laws for author's rights: adequate for digital preservation?

Introduction. Besides technical and economic-organisational problems, digital preservation also faces legal issues, especially regarding copyright legislation, since all digital preservation strategies involve copying materials and/or using software which is typically copyrighted. The purpose of this paper is to ascertain the extent to which current copyright laws meet the preservation requirements of library materials..Methodology. A cross-sectional analysis of recently updated national copyright laws as well as the impact of the other two protection methods: contractual and technological.Results. Even after the latest updates current copyright legislation is almost useless for digital preservation activities since the opportunities provided by WIPO Copyright Treaty to adapt and extend copyright exceptions and limitations have been used to the full.Conclusion. We need a legislation reform that will make it possible to carry out all required copying and communication activities and software use, even if circumventing technological protection is needed. But that is not enough for licensed works. The best solution for this kind of work is to include specific clauses in the licences that facilitate preservation activities. Thus, cooperation between both parties, libraries and rights' holders, is essential.

Library exceptions in the copyright laws of Ibero-American countries

The development of the digital setting has made it absolutely necessary to revise copyright legislation as a whole, including the exceptions that benefit libraries and similar institutions. Unfortunately, adaptation to the new technological reality is not taking place satisfactorily in most countries - the predominating trend is a refortification of copyright as opposed to user interests, and the maintenance of a certain pre-digital philosophy. In the case of Ibero-America the problem is twofold: aside from obsolescence or a lack of adaptation to the new technological setting, there are countries that have not yet included library-related exceptions in the national laws. Moreover, these happen to be developing countries, whose needs and interests do not coincide with those of the richer nations who paved the path to be followed by international treaties and copy- or copyright agreements. This study looks into the situation of exceptions to copyright to benefit libraries in the countries constituting Ibero-America, with a comparative analysis of the most significant characteristics of their national laws. It is concluded that it is crucial for these countries to take advantage of the options offered through the WIPO Copyright Treaty of 1996 and the results of the WIPO Development Agenda to update their legislation, in order that copyright will be respected, while at the same time making it easier for libraries to continue carrying out their social function in an adequate manner, always with the understanding of the developmental context of these countries.

Do professor informante ao professor parceiro: Reflexões sobre o papel da universidade para o desenvolvimento profissional de professores e as mudanças na escola

Este trabalho advoga a idéia de que os relacionamentos colaborativos entre universidade e escolas de 1º e 2º graus representam alternativa metodológica privilegiada tanto para investigação, quanto para atuação sobre o desenvolvimento profissional de professores e suas condições de trabalho. Projetos de natureza coletiva, que aproximam a pesquisa da realidade a ser estudada, como a pesquisa-ação colaborativa, constituem exemplos muito positivos de parceria entre universidade e escolas de 1º e 2º graus, porque geram oportunidades de exercício de práticas inovadoras no interior das escolas e o desenvolvimento de profissionais reflexivos em educação.Por se voltarem para a renovação simultânea de ambas as instituições envolvidas (universidade e escolas), de seus profissionais e de suas práticas, projetos colaborativos permitem, especialmente, que aprendamos mais sobre formas alternativas de iniciar e consolidar mudanças educacionais.

Os efeitos do FUNDEF nas políticas educacionais dos municípios mineiros

Este artigo tem por objetivo discutir os efeitos do FUNDEF sobre as políticas educacionais dos municípios de Minas Gerais. As análises estão balizadas em entrevistas realizadas com secretários municipais de educação de uma amostra de 22 municípios, entre novembro e dezembro de 2002. A análise leva em conta um conjunto de argumentos e hipóteses levantado pela literatura, o que inclui a tendência à busca de ganhos de escala e concentração de alunos e estabelecimentos; a possível melhora de remuneração e qualificação do corpo docente; o desenvolvimento de iniciativas de capacitação dos professores; a redução do uso dos recursos vinculados à educação para outros fins; o possível subinvestimento em educação infantil, ensino médio e educação de jovens e adultos, devido à sua exclusão do FUNDEF; e a possível insuficiência do valor de referência do Fundo.
