Este trabalho tem como objetivo o estudo da viabilidade econômica para a utilização da semente da Euterpe oleracea Mart. (açaí) como recurso energético na cidade de Belém-PA. Para isso foi feito um levantamento de campo dos pontos de venda e bairros de maior produção de açaí, realizando em seguida os ensaios das propriedades termogravimétricas das sementes: Teor de umidade, teor de voláteis, teor de cinzas, teor de carbono fixo e o poder calorífico superior. O levantamento dos pontos possibilitou a criação de um banco de dados, utilizando o software Microsoft Acess, o qual fornece relatórios com a identificação do nome do proprietário, assim como número de sacas que ele processa por dia, peso da saca e o potencial energético de cada produtor. Foi utilizado ainda o Microsoft ARC VIEW, de fácil interação com o Acess e que possibilitou a criação de um mapa atualizado dos pontos de venda para a cidade de Belém-PA. De posse desses dados passou-se para o estudo das rotas de transportes, através do Sistema de Informação Geográfica (SIG) GOOGLE EARTH. Foram determinadas rotas, através do método do Centróide, ou seja, o ponto de maior concentração da variável de estudo, neste caso, a semente de açaí, para o transporte da biomassa até seu destino final que é a UFPA, onde se encontra a usina que utiliza a biomassa como combustível para gerar energia. No cálculo da viabilidade econômica, utilizaram-se os parâmetros da usina de geração de energia elétrica do Grupo de Energia, Biomassa e Meio Ambiente EBMA, juntamente com os dados do consumo de energia elétrica da Universidade Federal do Pará - UFPA no período de 06/2006 a 06/2007, fazendo-se comparação nos valores obtidos nos levantamentos e a confirmação do quanto a UFPA economizaria em termos financeiros com a utilização da energia oriunda da queima de biomassa. Concluindo-se assim que a semente de açaí como recurso energético é economicamente viável para suprir toda a energia da UFPA, uma vez que o custo da energia elétrica fornecida pela Concessionária CELPA mostrou ser superior ao custo da geração com o sistema utilizado, ocorrendo assim, uma economia no valor final do consumo de energia elétrica.

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.

This paper analyzes the impact of implementing an information system, Enterprise Resource Planning - ERP, in a small business of the furniture industry. The goal this is show the impacts felt during and after implementation, showing behavioral and technological changes made by the study. The paper concludes by citing about the importance of cultural and behavioral changes for the good use of the system, besides showing the need to adapt to new technologies and ways of working to adapt to today's world of constant change and eternal conflict of the market

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

The objective of this paper is to show the development of a Geographic Information System (SIG) for the management of the Educational Centers of the city of Bauru. Currently, the Educational Centers and Assistance Institutes, public or private, in Brazilian cities have some problems, for example: they have no money to manage their institutions and they have no correct form to organize and to store the information. Because of these problems, we developed a system which will manage some informations for these institutions and local authority. This system will allow visualizing the data in the internet by the community. This pilot project has used the softwares SPRING 4.1 e SPRINGWEB 3.0.
