Projetos públicos compartilhados na visão de gerentes de uma agência de fomento em infraestrutura social

O objetivo da presente dissertação é descrever, a partir da visão dos gerentes de uma agência pública de fomento de infraestrutura social; de que forma os projetos públicos compartilhados podem ser mais eficientes com a adoção de ferramentas de gerenciamento de projetos. Para tanto, foi desenvolvido um estudo em três etapas: na primeira foram realizados observações e levantamento de evidências no ambiente de trabalho dos gerentes visando entender os projetos públicos compartilhados em suas circunstâncias. Na segunda etapa, foi aplicado um Survey exploratório em dois grupos: o “grupo agência”, formado apenas com gerentes da agência de fomento e o “grupo controle” composto por gerentes do setor privado e de outras empresas públicas, de modo a perceber como se comporta a opinião de cada grupo sobre os temas estudados. A terceira etapa consistiu em entrevistas abertas e semi-estruturadas com gerentes da agência de fomento, e posterior análise de conteúdo das falas, para o entendimento das questões propostas. Os resultados indicaram que: (i) o uso das ferramentas de gerenciamento aumenta a eficiência da execução dos projetos; (ii) as ferramentas utilizadas, como o Quadro Lógico e algumas ferramentas sugeridas pelo Guia PMBOK, permitiram uma visão clara dos objetivos do projeto, inclusive por parte dos parceiros regionais, além de garantir maior padronização de procedimentos; (iii) o uso da ferramenta Quadro Lógico ampliou a capacidade de mensuração dos resultados dos projetos, facilitando o seu monitoramento, e (iv) reduzindo os conflitos e a interferência política regional.

Encaminhamento óptimo do tráfego em redes Triple Play

A Internet é responsável pelo surgimento de um novo paradigma de televisão – IPTV (Televisão sobre IP). Este serviço distingue-se de outros modelos de televisão, pois permite aos utilizadores um elevado grau de interactividade, com um controlo personalizado sobre os conteúdos a que pretende assistir. Possibilita ainda a oferta de um número ilimitado de canais, bem como o acesso a conteúdos de Vídeo on Demand (VoD). O IPTV apresenta diversas funcionalidades suportadas por uma arquitectura complexa e uma rede convergente que serve de integração a serviços de voz, dados e vídeo. A tecnologia IPTV explora ao máximo as características da Internet, com a utilização de mecanismos de Qualidade de Serviço. Surge ainda como uma revolução dentro do panorama televisivo, abrindo portas a novos investimentos por parte das empresas de telecomunicações. A Internet também permite fazer chamadas telefónicas sobre a rede IP. Este serviço é denominado VoIP (Voz sobre IP) e encontra-se em funcionamento já há algum tempo. Desta forma surge a oportunidade de poder oferecer ao consumidor final, um serviço que inclua os serviços de Internet, de VoIP e de IPTV denominado serviço Triple Play. O serviço Triple Play veio obrigar a revisão de toda a rede de transporte de forma a preparar a mesma para suportar este serviço de uma forma eficiente (QoS), resiliente (recuperação de falhas) e optimizado (Engenharia de tráfego). Em redes de telecomunicações, tanto a quebra de uma ligação como a congestão nas redes pode interferir nos serviços oferecidos aos consumidores finais. Mecanismos de sobrevivência são aplicados de forma a garantir a continuidade do serviço mesmo na ocorrência de uma falha. O objectivo desta dissertação é propor uma solução de uma arquitectura de rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada através de um encaminhamento óptimo ou quase óptimo. No âmbito deste trabalho, é realizada a análise do impacto das estratégias de encaminhamento que garantem a eficiência, sobrevivência e optimização das redes IP existentes, bem como é determinado o número limite de clientes permitido numa situação de pico de uma dada rede. Neste trabalho foram abordados os conceitos de Serviços Triple Play, Redes de Acesso, Redes Núcleo, Qualidade de Serviço, MPLS (Multi-Protocolo Label Switching), Engenharia de Tráfego e Recuperação de falhas. As conclusões obtidas das simulações efectuadas através do simulador de rede NS-2.33 (Network Simulator versão 2.33) serviram para propor a solução da arquitectura de uma rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada.

Potencial solar dos edifícios públicos da RAM

As energias renováveis têm sido cada vez mais a alternativa encontrada para substituir o uso dos combustíveis fósseis na produção de energia. Neste contexto, surge a oportunidade de realizar um estudo sobre o “Potencial Solar dos Edifícios Públicos da RAM” como objeto de trabalho desta tese de Mestrado em Engenharia de Telecomunicações e Redes de Energia (METRE). Pretende-se que este estudo sirva para impulsionar o investimento nesta área por parte dos decisores regionais, dotando-os de um estudo do potencial de produção de energia solar nos edifícios públicos da RAM. Através de estudos desenvolvidos pelo LREC, ERAMAC - Maximização da Penetração das Energias Renováveis e Utilização Racional da Energia nas Ilhas da Macaronésia, e do Joint Research Centre (JRC), contendo dados do Instituto Meteorológico (IM), da Agência Regional da Energia e Ambiente da Região Autónoma da Madeira (AREAM), do LREC e do World Meteorological Organization (WMO), avaliou-se a radiação solar na RAM, através de tabelas e mapas de radiação solar, contendo a radiação solar global diária média mensal e média anual. Posteriormente fez-se uma análise da oferta do mercado atual de painéis fotovoltaicos (PV) em termos de eficiência, distinguindo as várias gerações de tipos de painéis introduzidos no mercado. Foram realizadas várias pesquisas em diversas áreas de energias renováveis e tecnologias existentes para, posteriormente, se realizar uma seleção e introspeção da informação essencial ao tema de forma a definir-se a fase de desenvolvimento desta tese. Com o auxílio da ferramenta computacional Quantum GIS, foram identificados alguns edifícios públicos com a dimensão e exposição solar apropriada para a colocação de sistemas solares nos mesmos. De seguida, foi realizado uma análise do preço pago/recebido por kWh consumido/produzido e cinco casos de estudos, nos quais foram focados os diferentes impactos de várias tecnologias solares nos prédios públicos da RAM, avaliando financeiramente os custos e retorno do investimento na aplicação destas tecnologias em cada caso, através das ferramentas computacionais, SolTerm e RETScreen. Finalmente retirou-se as respetivas conclusões acerca das opções tomadas, por exemplo, na escolha das tecnologias solares a implementar, os seus custos, o retorno do investimento, preços dos painéis fotovoltaicos, entre outros.

Avaliação do cuidado na estratégia saúde da família em metrópoles do nordeste brasileiro

Objective: To evaluate the implementation of the Family Health Strategy (FHS) in Brazilian cities of the Northeast, expanding coverage, analyzing the progress, challenges and innovations. Methods: Multicentric Evaluation Research, Studies Baselines in urban centers, using as a case study method. Selected cases of Aracaju, being capital, advanced coverage with extended team, and Fortaleza, capital coverage incipient and minimal staff. In Fortaleza, purposive sample of 11 Units Primary (APS), 03 managers, 53 professionals and 109 users. In Aracaju, 09 units of APS, 02 managers, 36 professionals, and 90 users. Structured interviews for managers, and structured to professionals and users. Descriptive analysis focusing on the political and institutional dimensions, organization and comprehensive care. Results: There was consensus that the ESF is the preferred port users and acts as inducing changes in care. In the case of Fortaleza, the specificities were: care protocols and community activities aimed at chronic conditions (100%) , with greater participation of doctors and nurses (93%) ; conjunction with more complex services, but the teams reported difficulties with the examination center and experts, the long waits and poor access to local services were the main difficulties reported by users., As innovative practice, the therapeutic group of elderly caregivers mentioned by respondents; There was intersectoral initiatives and teams 87 % of users have participated in meetings about health problems. In the case of Aracaju, care protocols were directed to the lines of care and formulated locally, 85 % coverage of the population with FHS counterpart local financing; employees hired by public tender; 70 % of teams with expertise in public health center for continuing education acting; democratization in management; access technologies, welcoming and computerization in different integrated networks, and evaluation matrix. Conclusions: The ESF has promoted access to health care and inclusion of disadvantaged populations. Different perceptions and practices in the organization of care, with distinct trajectories of reorganization. In the case of Fortaleza, predominance of model programs valuing older, with evidence of advances in care practices and teamwork, but restricted to primary care practices and incipient in public policy perspective. In Aracaju, had network integration with technologies related to the family, in which the ESF is consolidated as public policy. It can be argued that the XII APS expanding coverage, exhibited efficacy, despite the challenges inherent to the different degrees of implementation

Repercussões da terapia comunitária no processo de trabalho na estratégia saúde da família: um estudo representacional

The Community Therapy (CT) is in a practice of therapeutic effect and may also be considered as a technology takes care of the therapeutic procedure group, whose purpose is to promote health, prevent illness, developed within primary care in mental health. In this study we sought to understand the social representations of health professionals who work with the Community Therapy, on use of the Family Health Strategy (FHS) in the city of Joao Pessoa. This is a field research with a qualitative view Moscovician Theory of Social Representations, held with seven professionals of the FHS, therapists of Community Health District II. The empirical data were obtained by carrying out two thematic therapies in April 2009, which were wheeled CT. It was used as a technique for analyzing the collective subject discourse, and the data presented through graphs, charts, maps, pictures and graphics and arranged in three stages: Subjects of the study, characterizing the study participants; Social Representations of Therapist Community presenting and discussing the social representations of therapists community studied on CT, and Consequences of Community Therapy at the Family Health Strategy, discussing the meanings attributed by the study participants about changes in FHS. Meanings were attributed to the CT by the therapists studied originated from the speeches, songs, drawings and constructed, and that presented by schematic illustration show the relation between the representations: life, listening, faith / light, change, transformation. The web, symbol of CT, appeared on the images constructed by the representatives of the study and represents the formation of bonds that allows the construction of social support networks that strengthen relationships among community. In the study, proved by professionals who have the meanings about the changes in the work process from the introduction of CT, and shown that the change took place within a more welcoming attitude on the part of professionals, the relationship between Team members had no significant changes, explained by the low compliance of team members to the CT in relation to the user front, the bond was strengthened, and this involved strengthening the role of the therapist community. It is recognized, thereby transforming the character of CT in building links with users, requiring, however, that the team is viewed as offering therapeutic services, not the professional therapist. Therefore, the CT for being a new phenomenon in health services and community belonging, it fits like a novelty which affects the construction of a representation dispute. Still, can contribute to the reorganization of mental health care in line with the new model of mental health care advocated by the Psychiatric Reform.

Entre o sol e a liberdade impera a violência: formação de redes para a ação a partir da estratégia saúde da família

The research aimed to analyze the feasibility of forming a network of municipal services to prevent and treat child victims of violence from the Basic Health Units in the Family Mossoró / RN. The research is a qualitative approach and was developed in the form of action research. The population was composed of representatives of institutions of the child and primary care professionals. Data were collected through questionnaires, workshops and semi-structured interview. The results were analyzed from data collected through the questionnaire designed to assess the material, lectures, dialogues and assessments with the team and presented in accordance with the findings of the research. The study was approved by the Ethics in Research UFRN with protocol No. 158/2010, CAAE: 0176.0.051.000-10. Situational diagnosis in the participants answered a questionnaire to characterize and then launched the guiding question of the focus group FHS While professional what your perception towards violence against children? It was felt the fear and ignorance on the part of the unit staff on how to prevent and to refer cases of violence against children and adolescents in the area of coverage of the unit and also realized that the professionals felt victims of occupational violence before the violence has reached proportions that the area of the unit. Mind the need to change strategies to work to combat violence, we plan to conduct focus group workshop to complete the questionnaire, training for protection against occupational violence, and meeting with other bodies responsible visor protecting children and adolescents to draw the flowchart of the victims in safety net. The next moment training to fill the notification form professionals were interested in learning and use this tool to combat violence. At the third meeting in Unity, meeting with representatives of the Child Protection Council, the professional unit showed interest in interacting with the agency to expose and combat violence against children and adolescents. Due to difficulties in the physical structure of the unit was not possible to continue the research and planned every moment, and then completed the data collection with interviews with the participating professionals, to assess the meetings. Therefore, it is considered that action research has also achieved its goals because the team was involved in the collective construction of a proposed change in the practices of referral and prevention of violence against children and adolescents. This involvement was favored using the principles Freirian during the course of the study. However, it is assumed that the network was not fully implemented because it is known that it is in a continual process of improvement and must continue evolving with the unit team.

Algoritmo evolutivo paralelo para o problema de atribuição de localidades a anéis em redes sonet/sdh

The telecommunications play a fundamental role in the contemporary society, having as one of its main roles to give people the possibility to connect them and integrate them into society in which they operate and, therewith, accelerate development through knowledge. But as new technologies are introduced on the market, increases the demand for new products and services that depend on the infrastructure offered, making the problems of planning of telecommunication networks become increasingly large and complex. Many of these problems, however, can be formulated as combinatorial optimization models, and the use of heuristic algorithms can help solve these issues in the planning phase. This paper proposes the development of a Parallel Evolutionary Algorithm to be applied to telecommunications problem known in the literature as SONET Ring Assignment Problem SRAP. This problem is the class NP-hard and arises during the physical planning of a telecommunication network and consists of determining the connections between locations (customers), satisfying a series of constrains of the lowest possible cost. Experimental results illustrate the effectiveness of the Evolutionary Algorithm parallel, over other methods, to obtain solutions that are either optimal or very close to it

Gestão do Conhecimento e o uso estratégico de Tecnologias de Informação: um estudo em Redes de Franquias no Estado do Rio Grande do Norte

This study discusses the use of information technologies for knowledge management in networks of franchises in the Rio Grande do Norte/Brazil, whose management and operation are complex activities, characterized by the geographic spread of their network unities, creating barriers to communication and information sharing between franchisors, franchisees and final customers. In view of this, the following hypotheses were formulated: the knowledge management can be a positive alternative for improving communication between units; and information technology can eliminate many problems related mainly to capture and share knowledge. In general, it aims to investigate, in qualitative and quantitative aspects, how information technology can support knowledge management in networks of franchises. Specifically purposes to register the existence of managerial practices related to knowledge management in enterprises at the franchising sector; to verify whether they have the technological resources with the potential to facilitate the sharing of information; to identify what are the technologies of information and communication used in the organizational environment; and suggest measures that will facilitate the process of organizational learning, using information technology and communication as tools. It concludes that knowledge management becomes a positive alternative, especially in strengthening of bonds of communication and sharing of knowledge between the franchises. In this regard, information technology must provide all the services of the corporation to facilitate communication between franchisor and franchisee, through a single and integrated system. However, they still show unsuitable for more sophisticated technology platforms

Especificação de uma rede MPLS fim-a-fim com diferenciação de serviços

New multimedia applications that use the Internet as a communication media are pressing for the development of new technologies, such as: MPLS (Multiprotocol Label Switching) and DiffServ. These technologies introduce new and powerful features to the Internet backbone, as the provision of QoS (Quality of Service) capabilities. However, to obtain a true end-to-end QoS, it is not enough to implement such technologies in the network core, it becomes indispensable to extend such improvements to the access networks, what is the aim of the several works presently under development. To contribute to this process, this Thesis presents the RSVP-SVC (Resource Reservation Protocol Switched Virtual Connection) that consists in an extension of RSVP-TE. The RSVP-SVC is presented herein as a mean to support a true end-to-end QoS, through the extension of MPLS scope. Thus, it is specified a Switched Virtual Connection (SVC) service to be used in the context of a MPLS User-to-Network Interface (MPLS UNI), that is able to efficiently establish and activate Label Switched Paths (LSP), starting from the access routers that satisfy the QoS requirements demanded by the applications. The RSVP-SVC was specified in Estelle, a Formal Description Technique (FDT) standardized by ISO. The edition, compilation, verification and simulation of RSVP-SVC were made by the EDT (Estelle Development Toolset) software. The benefits and most important issues to be considered when using the proposed protocol are also included

Os Centros de Especialidades Odontológicas como suporte da atenção básica: uma avaliação na perspectiva da integralidade

The public dental services in Brazil were limited, practically, to the basic care, so that the specialized services acted, up to 2002, no more than 3,5% of the total of clinical procedures. That lower offer reveals the difficulty of continuity of the attention, that is, the comprehensiveness in the assistance, particulary, the reference and counter-reference system. Brasil Sorridente search to supply those needs when proposing Speciality Dental's Centers(CEOs Centros de Especialidades Odontológicas, Brazil) to compose the services of average complexity. In 2005, Ministry of Health enabled the three CEOs of Natal, located in the North II, East and West Sanitary Districts. This investigation evaluated the implantation of these CEOs, as support of the family health care teams, in the perspective of organization of the services in assistencial nets in Natal/RN. It was a study of evaluation, with qualitative approach and some quantitative data as contribution. Dentists, users and managers were interviewed to identify and to understand their perceptions, relationships and experiences in the daily of the services. The conceptual base that orientated the investigation was the principle of comprehensiveness, in its operational sense of the hierarchization in health attention levels. The collection of data was done with documental research, direct observation and semi-structured interview. The analysis was accomplished by triangulation of the extracted content from the used techniques and sources of interviewed groups depositions, looking for theoretical-conceptual support in specific bibliography. The results pointed aspects that go away from the comprehensiveness like: low resolution of problems in the basic net; little valorization of the space in the health units; traditional models of access to health services, insufficient offer for some specialties, compromising the reference and counter-reference system; practices centered in procedures in the CEO; bureaucratic directions from basic care to the specialized service; disintegrated and disjointed system among levels of attention; disrespect to the municipal protocol. On the other hand, there is an approach of compreensiveness in situations like: increase of the access and covering in the Family Health Strategy (ESF Estratégia Saúde da Família, Brazil); larger approach between professional and user; tendency to the quantitative and qualitative growth of specialized actions; punctual initiatives of relationships among levels; existence of protocol to guide professionals
