In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Although the records indicate the involvement of the City Christmas in the feeding system HiperDia, a survey conducted by the Health Ministry in 2004 found that the number of entries made in Natal was well below estimate. In order to understand the functioning of HiperDia, we performed this study to analyze the actions taken by the professionals involved in power system HiperDia in Natal / RN. The research has developed into a quantitative perspective, with the design of exploratory case study conducted in the health services that integrate the various levels of the organization who are directly involved with the process of system power HiperDia in Natal / RN , represented here by SMS, health districts and the Family Health Units in the period from August to October 2008.Study participants were 110 professionals, including nurses, physicians, operators, administrator and a coordinator. The survey results showed that feeding HiperDia in Natal was maintained mainly by health professionals and operators. Activities include carrying out the state registration, monitoring, and updating of data transfer routines. They report that the difficulties in the process of feeding data are related to the work of teams and / or lack of structure of the Program of Hypertension and Diabetes (HA and DM), the discontinuity of federal investments in improving the HiperDia and lack of training. We can see then that the process of feeding system on Christmas HiperDia therefore is developing the three levels (SMS, districts and health units), however is not matching the expectations established by MS, considering that the gaps the flow of information are undermining the end result of this process

Planning and sustainable management of water resources require actions that focuses on life quality, recovery and preservation of natural resources. As such, a municipality must have tools which empower the government with the right to exercise such actions, for example, the Master Plan and Sector Plans. To develop municipal plans which will guide the development of the city and provide information for establishment of public policies, it is of the utmost importance that they are designed based on primary and safe data. In view of these considerations, this study aimed at formulating environmental indicators by using a Geographic Information System – GIS. The environmental diagnosis based on the gvGIS was used as database, which made the process to be agile and accurate. The watershed of Lençóis River – SP was the study area. It has a good database from the Environmental Diagnosis of the watershed of Lençóis River, which was created through funds from the State Funds for Water Resources – FEHIDRO. The borrower was the Service of Water Supply and Sewage of Lençóis Paulista – SAAELP. Based on the diagnosis, the indicators were formulated concerning land use and occupation as well as water resources. The results were considered satisfactory and showed that the methodology used in this study is of great importance to evaluate water resources, as it provides a reliable basis for the decision-making process seeking environmental compliance and sustainable development. By using environmental indicators, the sustainability of an area as a whole can be analyzed, and the parts as well, i.e., it is possible to identify which sector is experiencing significant problems and take actions to solve them.

Os meios urbanos são espaços cada vez mais edificados, compactos e com solos impermeabilizados, onde a ausência ou reduzida presença de espaços verdes é uma realidade. Os elementos arbóreos, qualquer que seja a sua disposição, ganham cada vez mais significado enquanto representantes do meio natural na conservação da qualidade e conforto de vida nas cidades. Este trabalho desenvolveu-se a partir do tema das árvores em meio urbano, tendo por base os benefícios das árvores nas cidades, a sua distribuição espacial e o estado de conservação deste tipo de património. O principal fio condutor passou pela concepção do inventário do Património Arbóreo da cidade de Portalegre, com recurso às novas tecnologias da informação, nomeadamente os Sistemas de Informação Geográfica, capaz de se integrar nos sistemas homólogos do Município de Portalegre. O inventário à escala do perímetro urbano da cidade de Portalegre contabilizou 2087 elementos arbóreos localizados em áreas públicas, dos quais 1500 são árvores de folha caduca e 587 são perenifólias. Registou-se um elevado índice de diversidade para aquela área, cerca de 705 árvores/km2, embora as árvores estejam distribuídas de forma heterogénea pelo território considerado, percebendo-se com isso as zonas de carência de arborização. Com este inventário foi ainda possível conceber uma avaliação económica segundo a Norma de Granada, de 13 árvores isoladas e uma alameda com 38 indivíduos, assim como propor a classificação destes elementos a Árvores de Interesse Público. Anseia-se que este trabalho seja um documento informativo e sensibilizador de todo o público em geral, mas principalmente que se assuma como uma ferramenta útil aos responsáveis pelos espaços verdes da cidade de Portalegre.

O Grupo de Investigação de Bioacústica e Sistemas (GIBS) da Escola Superior Tecnologia da Saúde de Coimbra proporciona várias actividades entre as quais o desenvolvimento de softwares aplicados na área da saúde. Neste trabalho vai ser abordado este tema, em particular, o teste “Peabody picture vocabular test”, um dos testes desenvolvidos no GIBS que vai ser associado a um sistema de informação, por forma a automatizar e dinamizar o procedimento do teste. O teste consiste em disponibilizar uma série de imagens a uma criança, que vai seleccionar as que conhece. Esta escolha tem em conta a idade da criança, bem como o seu desenvolvimento cognitivo, por isso este conjunto de imagens é amplo. Das imagens que a criança seleccionar, o protótipo vai gerar um conjunto de quatro imagens aleatórias, e reproduzir o som alusivo a uma delas. Dado que a criança seleccionou as imagens, caso não consiga identificar existe um potencial problema e o técnico encontra-se em condições de poder realizar mais testes para o identificar. No caso de identificar, o teste decorre sem problemas sendo que no final, o técnico terá acesso aos dados verificando quantas acertou em cada uma das intensidades apresentadas. Estas informações podem ser para cada um dos ouvidos em separado, caso se utilizem auscultadores, ou para ambos os ouvidos se o exame for realizado em campo livre. Actualmente o teste é realizado, numa sala acústica auxiliada por um audiométrico, que ajuda a regular a intensidade do som reproduzido e para qual dos ouvidos vai ser reproduzido. Essas mesmas condições serão mantidas. No entanto, o audiómetro funcionará em conjunto com um computador, com uma versão do protótipo a “correr”, substituindo os cartões com as imagens utilizados actualmente. Para além de ser um sistema totalmente automático, conta ainda com a vantagem de armazenar todas as variáveis associadas a cada teste, desde os dados do utente, os dados do técnico (utilizador), os dados do teste e os resultados. A fim de validar este protótipo, foi empreendido um grupo de experiências, abrangendo aspectos particulares e distintos em cada um deles, verificando-se a adequação do modelo e a utilidade do recurso, automatizado, à experiência passada. Os resultados obtidos nesta avaliação permitem considerar que o protótipo cumpre os requisitos pré-estabelecidos.

Atualmente, devido às necessidades de satisfazer cada vez mais e melhor o cliente, a logística tornou-se reconhecida como uma área de grande oportunidade, pois encontramos na logística uma poderosa “ferramenta”, que ajudará a mudar conceitos, rever processos, quebrar paradigmas, ou seja, fazer mais com menos. As empresas estão finalmente a descobrir a logística. Algumas veem-na como uma grande oportunidade competitiva, outras, como uma ameaça diante da concorrência. Logística é um ramo da gestão cujas atividades estão voltadas para o controlo e gestão dos fluxos quer materiais, quer de informação, suportados num adequado planeamento dos recursos materiais, financeiros e humanos da organização. Neste âmbito, a implementação de Sistemas de Informação (SI’s), possibilita o acesso a informação relevante e fiável, promovendo a melhoria de grande parte dos processos logísticos e tornando-os mais ágeis. Assim, neste trabalho propõe-se o desenvolvimento de uma base de avaliação de SI’s, com aplicação à Gestão de Armazém ou Warehouse Management Systems (WMS´s), que permita identificar a adequação do sistema aos objetivos logísticos da organização. Para tanto, efetuou-se um levantamento de um conjunto de SI’s, procedeu-se à sua caracterização e identificaram-se as funcionalidades implementáveis à Gestão de Armazém. Construiu-se uma tabela de funcionalidades e a respetiva matriz de decisão e uma aplicação (em Excel) que procura auxiliar na identificação do SI, de entre os analisados, que mais se adequa aos seus propósitos logísticos. Foi implementado um questionário online (Google Drive), como mecanismo de recolha dos dados e opções das organizações interessadas neste tipo de avaliação. O trabalho desenvolvido permitiu concluir que, a implementação de um processo prévio de seleção do WMS, como o implementado neste trabalho, representa um potencial de redução de custos pelo facto de permitir a consolidação das funcionalidades dirigidas aos requisitos do cliente, evitando o investimento em suportes de complexidade não coerente com as suas necessidades. No entanto, critérios de seriação como o custo de cada SI não foram contemplados pelo facto de dependerem significativamente do tipo e dimensão da empresa cliente. Paralelamente, salienta-se a oportunidade de desenvolvimento de um Script que permita gerar, em modo automático, os resultados do questionário online; considerando-se igualmente pertinente a análise de novas métricas, tendo em vista a melhoria da adequabilidade dos indicadores logísticos às avaliações pretendidas pelas organizações.
