Espacialização de informações na gestão de sistemas de abastecimento de água utilizando sistema de informação geográfica

Avaliar a espacialização de informações na gestão de Sistema de Abastecimento de Água (SAA). Para isso, foram definidos e adotados os dados da pesquisa (Fase 1), sendo dividido em dados de perdas reais, comerciais e Despesas de exploração. Na Fase 2, a base cartográfica da área de estudo e os dados adotados foram armazenados e organizados em Sistema de Informação Geográfica (SIG), utilizando o software ArcGis 9.3, onde foi construído o modelo de dados para a pesquisa, e definida a topologia a ser utilizada para identificação dos dados espacializados, a construção do banco de dados georreferenciado e a criação dos layers. Na fase 3 foi realizado o cálculo do balanço hídrico nas principais unidades dos SAAs estudados sendo determinadas as perdas na adução de água bruta, no tratamento, na reservação, e na distribuição. Na fase 4 foram calculados indicadores para avaliar o desempenho dos SAAs, como: índice de cobertura, índice total de perda real, índice de perda na arrecadação, índice de perda de faturamento, índice de consumo de energia em SAA, índice de despesas com energia elétrica, entre outros. Na fase 5 foi proposta a espacialização e apresentação em SIG dos resultados obtidos nas fases anteriores. Com isso, considerando os dados adotados, foi possível identificar os valores das perdas reais e dos indicadores de desempenho em cada setor do SAA estudado, sendo, por exemplo, o setor 9, o que apresentou maior índice de perda total, chegando a 59,10%, seguido dos setores 4, 8 e 5. A perda mais significante para o sistema foi a perda na distribuição, com o setor 9 apresentando perda de 57%; a perda no tratamento foi de 3,4%, no setor 3; e os setores com maior índice de perda na adução, foram os setores 6 e 8, com 3,5%. Os percentuais de água não faturada, foram maiores nos setores 1 e 5. Os setores 1, 3, 4 e 6 são os que apresentaram maior consumo de energia elétrica por volume de água produzido. Portanto, a espacialização dos dados em SIG facilitou a visualização e análise dos dados adotados na pesquisa.

Avaliação da Suscetibilidade a Movimentos de Massa no Município de Várzea Paulista (SP) Utilizando os Sistemas de Informação Geográfica

O objetivo deste trabalho foi identificar e mapear áreas suscetíveis a movimentos de massa, por meio das geotecnologias, no município de Várzea Paulista (SP). Para o propósito, foram utilizados os mapas de declividade, geológico, geomorfológico e de uso e ocupação da terra, que foram sobrepostos por meio da Análise Multicritério no SIG ArcGIS. Cada tema recebeu seu peso de influência para deflagração de tais processos e como resultado final foi obtido o mapa de suscetibilidade a movimentos de massa do município em questão. Paralelamente foi elaborado o estudo da orientação de vertentes, para determinação daquelas que apresentam maiores riscos em comparação com os dados coletados em campo. Constatou-se que existem muitas áreas ocupadas dentro do município que carecem de monitoramento do Poder Público, principalmente nos meses chuvosos, pois se encontram em locais frágeis do ponto de vista geológico-geomorfológico.

Metodologia para gerenciamento de projetos em tecnologia da informação baseada no guia PMBOK: um estudo de caso na Secretaria de Estado da Saúde Pública do Rio Grande do Norte

Nowadays the search for growth makes organizations seeking competitive advantages, project management shares this goal, through techniques that assist in the search for an improved management of the various fields of knowledge through a design methodology. The world is driven by projects and the search for ways to better manage activities such as time, cost and term towards the success of a particular project is something constant. A major contribution that IT can make to the health sector is the support for the management area. IT can integrate processes, optimize the interconnection between the various sectors, make hospitals have access to inside information of good quality, as well as support in the healthcare area, sharing pictures, uniting the various aspects of nursing and nursing service. The major challenge faced by the SESAP Information Technology sector at present is in project management in IT , which does not exist makes investments in the area are increasingly difficult due to this deficiency in management develop their own systems without cost additional to the State. This study seeks to build and strengthen the Project Management within the Department of Health through the implementation of a project office that will manage the final result of this work methodology based on PMBOK, and still show the functionality applied to development the state Hospital Management System that will later be installed on all Regional Health Units and proposing measures for the sustainability and development of the sector amid the difficulties of the current public service. Such action will result in a savings of more than R$ 107,000.00 (one hundred seven thousand) regarding spending private software currently used by the assignment of invested by the State of Rio Grande do Norte user licenses, representing more than 5 % of the total budget of the State Department of Public Health of the State

iSalud: uma arquitetura para publicação e distribuição de sistemas de informação para o SUS

The Brazil Telehealth Networks Program was established by the Ministry of Health in 2007. Its main objective is to support professionals in Primary Health Care (PHC) by offering educational qualification, resulting in more favorable conditions to fixate the professional in remote areas. The formulation and management of telehealth services are performed by scientific and technical centers that are operated by public institutions of higher education and responsible for providing tools and services in the context of the regions where they are. However, one of the problems generated by this decentralization is the development of various tools with different types of language, architecture and without any regulation and integration of information with the Ministry of Health. Aiming to solve the above problem, we propose the specification, implementation and validation of an architectural model in the development and distribution of the Unified Health System software tools. This proposed architecture enables tools developed in telehealth center to be shared among the other centers, thereby preventing the unnecessary use of resources.

Aplicação dos Sistemas de Informação Geográfica nas energias renováveis: o potencial da energia solar na ilha de São Vicente – Cabo Verde

Informação Geográfica (SIG) ao estudo das energias renováveis, tendo como caso avaliar o potencial solar na ilha de São Vicente do arquipélago de Cabo Verde. A energia do sol é a principal fonte de energia renovável, e está disponível em quase todas as regiões do planeta. Quantificar o potencial energético solar de um lugar ou região é indispensável, para avaliar as potencialidades de produção de energia fotovoltaica. Outro fator importante prende-se com ordenamento territorial associado à exploração desses recursos energéticos, pelo que devem ser avaliadas as condições técnicas, ambientais e económicas, quando se pretende instalar parques para a produção de energia fotovoltaica. Assim, neste trabalho foram aplicadas as ferramentas SIG, para quantificar a radiação solar mensal e anual da ilha de São Vicente, arquipélago de Cabo Verde, através do modelo Solar Analyst. Numa segunda fase, aplicou-se a técnica de análise multicritério em combinação com os SIGs para definir as áreas mais favoráveis para a instalação de parques de produção de energia elétrica a partir da energia solar. Para o cálculo da radiação solar na ilha de São de Vicente, utilizou-se o modelo digital de terreno (MDT) e a latitude da ilha como parâmetros de entrada ao modelo. Para a análise multicritério definiram-se um conjunto de critérios que devem ser considerados na implementação de parques solares, nomeadamente, a disponibilidade de radiação solar existente na área, a distância à rede de transporte de energia elétrica e à rede viária, o declive do terreno, o uso e ocupação do solo e a proximidade às linhas de água. Para auxiliar na atribuição dos pesos aos critérios utilizados na análise aplicou-se a método Analytic Hierarchy Process (AHP). As áreas resultantes do processo da análise multicritério, foram confrontadas com a Carta de Condicionantes do esquema regional de ordenamento da ilha de São Vicente, aferindo a conformidade das propostas e reajustes subsequentes, de modo a obter os resultados finais.

Construção das capacidades organizacionais de tecnologia da informação no contexto dos sistemas institucionais integrados de gestão da UFRN

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN
