As 20 experiências finalistas de 2002 representam bem a riqueza do material recebido pelo Programa, tanto no que se refere à abrangência geográfica quanto à diversidade de áreas de atuação. Em relação ao primeiro aspecto, por exemplo, chama a atenção a presença de duas experiências de Roraima (Programa Braços Abertos, de Boa Vista, e Projeto Anike), no extremo norte do país, e de outras quatro da região Sul (Cidadania em Cadeia para o Direito do Futuro, do Presídio Masculino de Florianópolis; Formação de Parcerias e Geração de Renda nas Comunidades Rurais, de Lontras-SC, Licenciamento Ambiental para Redes de Infra-Estrutura Urbana, de Porto Alegre e Consórcio Intermunicipal de Resíduos Sólidos Urbanos – Citresu, de dez municípios gaúchos).

Esta dissertação tem como principal objectivo, propor um sistema de comunicações para as Ilhas Desertas que vise atender às necessidades expostas pelo PNM - Parque Natural da Madeira. Localizadas a 22 milhas marítimas do Funchal, as ilhas Desertas não dispõem de cobertura da rede móvel GSM - Global Standard for Mobile, nem de qualquer outra infra-estrutura de comunicações que permita a comunicação entre os vigilantes e a estação de serviço - doca. Esta falta de comunicação torna-se mais problemática aquando da realização de acções de fiscalização e vigilância, já que em caso de acidente não será possível pedir auxílio. Dada esta realidade propomos a criação de uma rede de rádio móvel terrestre para as Ilhas Desertas, com a instalação de vários repetidores UHF no topo das ilhas. O projecto desta rede será fundamentado com a realização de um estudo de cobertura para as três ilhas que incluirá a avaliação e análise de vários modelos de propagação. Esta análise é realizada com recurso a duas ferramentas de software, Radio-Mobile e DifractionLoss, tendo este último sido desenvolvido no âmbito desta dissertação. De forma a melhorar a cobertura da rede GSM na estação de serviço do PNM na Deserta Grande, sugerem-se duas soluções: a primeira consiste na instalação de um repetidor GSM de frequência deslocada e a segunda na instalação de uma NanoBTS. Além da falta de comunicação na área das ilhas Desertas, a falta de comunicação com a ilha da Madeira é também uma realidade. Perante esta situação sugere-se a criação de uma ligação por feixes hertzianos de alta frequência entre a estação de serviço do PNM na Deserta Grande e a sede do PNM, localizada na zona do Jardim Botânico na Ilha da Madeira. O projecto desta ligação apresenta um planeamento e dimensionamento de acordo com as necessidades apresentadas pelo PNM, assim como um estudo de propagação baseado num procedimento teórico e em simulações de software. É também proposto um sistema de videovigilância controlado remotamente com o objectivo de permitir a monitorização remota dos lobos-marinhos.

No contexto das tecnologias propostas pela OMG, o MOF é utilizado para definir a sintaxe de linguagens de modelação, contudo, os aspectos semânticos não podem ser capturados usando esta linguagem. A descrição dos aspectos não sintácticos é realizada com recurso à linguagem OCL. Consequentemente, para uma completa definição de uma linguagem de modelação é necessário incorporar o OCL no MOF, criando uma infra-estrutura que possui a expressividade necessária para realizar esta função. Este projecto visa complementar a ferramenta de metamodelação MetaSketch Editor, introduzindo a capacidade de executar expressões em OCL e permitindo, desta forma, a verificação semântica dos modelos construídos usando o MetaSketch Editor. A gramática da linguagem OCL adoptada está de acordo com a especificação elaborada pela OMG (2006-05-01), juntando-se algumas contribuições de trabalhos existentes sobre esta linguagem. O projecto envolveu a implementação de um parser com recurso ao sistema GOLD Parser, a implementação da standard library do OCL em C# e, por último, a implementação de uma estratégia de execução das expressões em OCL.

O presente estudo tem como tema a Prática Pedagógica Alfabetizadora bilíngue numa escola indígena: um estudo de caso na Escola Diferenciada de Ensino Fundamental e Médio Maria Venâncio. A pesquisa de abordagem do tipo etnográfico teve como foco central a prática pedagógica realizada no contexto da escola diferenciada e insere-se na linha de pesquisa de Inovação Pedagógica. Localizada no interior do estado do Ceará, em Itarema, na praia de Almofala, a escola pesquisada é considerada vitória da luta do povo Tremembé que ressurgiu no cenário nacional após os direitos conquistados com a Constituição Federal de 1988. Inicialmente a investigação visava observar o ensino bilíngue no âmbito da sala de aula. Porém, o mesmo não foi encontrado no universo escolhido para a pesquisa. Mesmo assim, a escola diferencia-se das escolas convencionais, rompendo com a infra-estrutura padrão, tendo uma organização docente e social únicas, onde a figura do cacique é fundamental tanto para os assuntos políticos, sociais, quanto pedagógicos. O Projeto Político Pedagógico fundamenta-se em suas tradições e práticas culturais e suas normas de conduta são os valores do povo Tremembé. Durante a observação participante, constatámos que o papel da escola vai muito além da sala de aula. A escola diferenciada é lugar de reinvenção da identidade indígena e resgate das práticas culturais que se sobrepõem ao modelo fabril, configurando uma ruptura do paradigma atual.

Some sectors in Brazil are earning notoriety in the international market, configuring itself in dynamic areas for the Country. The most typical case is the agribusiness. Rio Grande do Norte state has important role, because 90% of the output of the melon exported by Brazil is produced at Assu/Mossoró. The present work planned to verify the evolution of the culture of the melon produced at Assu/Mossoró area, from 1990 to 2003. Through descriptive research, utilizing the case study and documentary analysis of secondary data this work showed the evolution of the area reaped of melon in the pole Assu/Mossoró, the quantity produced of melon and of the value of the output of the melon between 1990 and 2003. The research verified that all of the factors studied show growth during the analyzed period, showing up the importance of the agribusiness for the region. However the analysis shows the vulnerability of the sector concerning external macroeconomics factors, such as the exchange rates. Showing the importance and/or dependence of the producers for public actions to development of the culture, that might be on areas like infrastructure, economics or taxes

New technologies appear each moment and its use can result in countless benefits for that they directly use and for all the society as well. In this direction, the State also can use the technologies of the information and communication to improve the level of rendering of services to the citizens, to give more quality of life to the society and to optimize the public expense, centering it in the main necessities. For this, it has many research on politics of Electronic Government (e-Gov) and its main effect for the citizen and the society as a whole. This research studies the concept of Electronic Government and wishes to understand the process of implementation of Free Softwares in the agencies of the Direct Administration in the Rio Grande do Norte. Moreover, it deepens the analysis to identify if its implantation results in reduction of cost for the state treasury and intends to identify the Free Software participation in the Administration and the bases of the politics of Electronic Government in this State. Through qualitative interviews with technologies coordinators and managers in 3 State Secretaries it could be raised the ways that come being trod for the Government in order to endow the State with technological capacity. It was perceived that the Rio Grande do Norte still is an immature State in relation to practical of electronic government (e-Gov) and with Free Softwares, where few agencies have factual and viable initiatives in this area. It still lacks of a strategical definition of the paper of Technology and more investments in infrastructure of staff and equipment. One also observed advances as the creation of the normative agency, the CETIC (State Advice of Technology of the Information and Communication), the Managing Plan of Technology that provide a necessary diagnosis with the situation how much Technology in the State and considered diverse goals for the area, the accomplishment of a course of after-graduation for managers of Technology and the training in BrOffice (OppenOffice) for 1120 public servers

Due to the appreciation of family farming by the Brazilian Federal Government, the Technical Assistance and Rural Extension was induced to restructure and act in a more participative way, culminating in the National Policy of Technical Assistance and Rural Extension (PNATER), changing the profile of technology transfer and knowledge (diffusionism) for an action that uses participatory methodologies focused on exchange of knowledge between farmers and technicians. The process of discussion of the trends of ATER brought the New ATER , with the recognition of agroecology as the main guidance. This research aimed to analyze methods of public ATER developed by institutions of Rio Grande do Norte, under the guidance of New ATER. The research is qualitative. Secondary data were collected through documental research and literature. Primary data were collected through a set of interviews applied to representatives of public institutions ATER, namely EMATER-RN, Diaconia and AACC and representatives of organizations that receive public ATER. The research showed the difficulties of EMATER-RN in implementing of New ATER due to lack of infrastructure and low adherence of the new form of technical assistance and rural extension. It was shown also that the AACC and Diaconia act with ATER through projects with implementation deadlines set, often interrupting ATER while communities are still in need of assistance

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

Both the end of the twentieth century and the beginning of the twenty-first century have been characterized as a period of major political, economic, social and cultural transformations. Two of the major consequences of the political-economical crisis of the end of last century are the restructuring of capitalist production, and the consolidation of neoliberalism as a worldwide phenomenon. This new world political-economical scenario has influenced, in a dialectic way, the contemporary urban development. In that sense, "new" spatial processes and new paradigms in both urban management and urban planning have gained shape. In this context of urban transformations, the central areas of western cities, also known as historic centers, are being increasingly (re)valued. Since the Second World War, the historic centers urban areas which have great infrastructure and symbolic relevance had been undergoing a process of evasion of population and activities, undeniably linked to the neglect of government authorities. However, in recent decades, the question of historic centers rehabilitation has acquired a growing interest, academically and in political agendas. The object of this dissertation is to focus on how the government of each Brazil and Portugal has dealt with the issue of historic center rehabilitation through programs of urban rehabilitation

The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use
