Um ambiente para especificação e execução AD-HOC de processos de negócio baseados em serviços Web

Recently the focus given to Web Services and Semantic Web technologies has provided the development of several research projects in different ways to addressing the Web services composition issue. Meanwhile, the challenge of creating an environment that provides the specification of an abstract business process and that it is automatically implemented by a composite service in a dynamic way is considered a currently open problem. WSDL and BPEL provided by industry support only manual service composition because they lack needed semantics so that Web services are discovered, selected and combined by software agents. Services ontology provided by Semantic Web enriches the syntactic descriptions of Web services to facilitate the automation of tasks, such as discovery and composition. This work presents an environment for specifying and ad-hoc executing Web services-based business processes, named WebFlowAH. The WebFlowAH employs common domain ontology to describe both Web services and business processes. It allows processes specification in terms of users goals or desires that are expressed based on the concepts of such common domain ontology. This approach allows processes to be specified in an abstract high level way, unburdening the user from the underline details needed to effectively run the process workflow

Cloud Integrator: uma plataforma para composição de serviços em ambientes de computação em nuvem

With the advance of the Cloud Computing paradigm, a single service offered by a cloud platform may not be enough to meet all the application requirements. To fulfill such requirements, it may be necessary, instead of a single service, a composition of services that aggregates services provided by different cloud platforms. In order to generate aggregated value for the user, this composition of services provided by several Cloud Computing platforms requires a solution in terms of platforms integration, which encompasses the manipulation of a wide number of noninteroperable APIs and protocols from different platform vendors. In this scenario, this work presents Cloud Integrator, a middleware platform for composing services provided by different Cloud Computing platforms. Besides providing an environment that facilitates the development and execution of applications that use such services, Cloud Integrator works as a mediator by providing mechanisms for building applications through composition and selection of semantic Web services that take into account metadata about the services, such as QoS (Quality of Service), prices, etc. Moreover, the proposed middleware platform provides an adaptation mechanism that can be triggered in case of failure or quality degradation of one or more services used by the running application in order to ensure its quality and availability. In this work, through a case study that consists of an application that use services provided by different cloud platforms, Cloud Integrator is evaluated in terms of the efficiency of the performed service composition, selection and adaptation processes, as well as the potential of using this middleware in heterogeneous computational clouds scenarios

Uma máquina de redução de grafos para serviços web

Web services are software accessible via the Internet that provide functionality to be used by applications. Today, it is natural to reuse third-party services to compose new services. This process of composition can occur in two styles, called orchestration and choreography. A choreography represents a collaboration between services which know their partners in the composition, to achieve the service s desired functionality. On the other hand, an orchestration have a central process (the orchestrator) that coordinates all application operations. Our work is placed in this latter context, by proposing an abstract model for running service orchestrations. For this purpose, a graph reduction machine will be defined for the implementation of service orchestrations specified in a variant of the PEWS composition language. Moreover, a prototype of this machine (in Java) is built as a proof of concept

Lazer e urbanização: a dinâmica do setor de serviços no litoral de Parnamirim e Nísia Floresta - RN

The research here undertaken analyzes the process of urbanization on the coast of Panamirim - RN and Nísia Floresta - RN, arising from leisure, the main leisure expression was considered the second residence and coastal tourism. The leisure promoted the growth of businesses and public and private services to meet consumer demand in that area, which initially occurred with users of second home, and which also gradually begin to occupy the coastline of these municipalities in 1980 and more recently with the development of tourism in the 1990s until now. To undertake such an analysis, we did the georeferencing about the trade and also public and private services of that coast, characterizing them; evaluated the extent to which services deployed in this area meets the demands of tourists and users of second residence; it was also identified how the centrality of Natal interferes in the expansion of services in these locations. The spatial area of research includes the coastal municipalities of Parnamirim and Nísia Floresta, considering the limits of the census of the Instituto Brasileiro de Geografia e Estatística- IBGE, and about the time frame, it was considered the 1990s to the present day. The methodology consists of: 1. survey and reading of the literature related to the researched topic, serving as the theoretical analysis in the construction of the object studied; 2. collection and organization of secondary data by the IBGE and tourism sectors of the State of Rio Grande do Norte, Natal and main municipalities of the research; 3. Questionnaires and / or interviews with the traders, service providers, tourists, users of second homes, local residents, and government. The analysis of such data collected allowed the preparation of graphs, maps and tables that illustrate the results obtained in the research field, basing so the study. The relevance of the study is shown by the extensive survey data involving agents of the research, including tourists, users of second homes and, above all, the data for the service sector that did not exist in the analyzed area. The study results identified in the area analyzed the emergence of three new centers, arising from the urbanization process from leisure, one of them located in the municipality of Nísia Foresta Beach in Barra de Tabatinga, and two in Parnamirim, more specifically in locality Pium and Beach Pirangi do Norte. It was further observed that, being located in tourist areas, the main feature of these new centers is seasonality

Fatores envolvidos na migração das endopróteses em pacientes submetidos ao tratamento endovascular do aneurisma da aorta abdominal

A migração da endoprótese é complicação do tratamento endovascular definida como deslocamento da ancoragem inicial. Para avaliação da migração, verifica-se a posição da endoprótese em relação a determinada região anatômica. Considerando o aneurisma da aorta abdominal infrarrenal, a área proximal de referência consiste na origem da artéria renal mais baixa e, na região distal, situa-se nas artérias ilíacas internas. Os pacientes deverão ser monitorizados por longos períodos, a fim de serem identificadas migrações, visto que estas ocorrem normalmente após 2 anos de implante. Para evitar migrações, forças mecânicas que propiciam fixação, determinadas por características dos dispositivos e incorporação da endoprótese, devem predominar sobre forças gravitacionais e hemodinâmicas que tendem a arrastar a prótese no sentido caudal. Angulação, extensão e diâmetro do colo, além da medida transversa do saco aneurismático, são importantes aspectos morfológicos do aneurisma relacionados à migração. Com relação à técnica, não se recomenda implante de endopróteses com sobredimensionamento excessivo (> 30%), por provocar dilatação do colo do aneurisma, além de dobras e vazamentos proximais que também contribuem para a migração. Por outro lado, endopróteses com mecanismos adicionais de fixação (ganchos, farpas e fixação suprarrenal) parecem apresentar menos migrações. O processo de incorporação das endopróteses ocorre parcialmente e parece não ser suficiente para impedir migrações tardias. Nesse sentido, estudos experimentais com endopróteses de maior porosidade e uso de substâncias que permitam maior fibroplasia e aderência da prótese à artéria vêm sendo realizados e parecem ser promissores. Esses aspectos serão discutidos nesta revisão.

A saúde ambiental e os resíduos de serviços de saúde nos três níveis de complexidade do Sistema Único de Saúde - SUS

The environmental management in the health establishments is a reality still little explored in the health sector in Brazil, especially concerning its wastes. The management of wastes of health services is established in the valid legislation through the National Council of Environment and Sanitary Vigilance Agency (358/2005 and 304/2004 respectively). The present work is about a descriptive work about the environmental health in the health services. The used criterion was to diagnose the environmental management in twelve establishments of health inserted in the three levels of complexity of the Unique Health System (Sistema Ùnico de Saúde SUS). Among the sub criteria used the waste management is the one of bigger concern. The one referring to the water quality is considered good. The analysis of data reveals that 66% of the establishments got a poor environmental ranking, 17% critical and 17% appropriate, showing that the health establishments in the three levels of complexity of the SUS need urgent structural, environmental and educational interventions

A redefinição do espaço urbano de Natal/RN a partir da influência dos serviços: uma análise das avenidas Bernardo Vieira e Engenheiro Roberto Freire

This paper analyzes the influence of trade and services in the reconfiguration of urban space in Natal, with the Avenues Bernardo Vieira end Roberto Freire Engineer as privileged analysis. Initially, we discussed the concepts of production and reproduction of urban space, urban centralities, decentralized, services and public policies, especially transport and tourism. Then, we show the construction of urban space from Natal, highlighting the historical formation of the districts of Ribeira, Cidade Alta and Alecrim, pioneers in the service sector, noting that currently there is an ongoing process of decentralization in the city of such activities, to other areas of the urban fabric of Natal. Later, we studied the Avenues Bernardo Vieira to Roberto Freire Engineer, noting, in both the distribution of commercial activities and services, and issues related to transportation, traffic, tourism and socio-economic problems, identified them. Finally, testify that Natal, from the 1980s, underwent a process of decentralization of services, both to the south, and north of the city on the ball. In this process of decentralization we ascertain the role of public policies on transport and tourism, complementing the action of private enterprise, through the real estate market, on Avenue Roberto Freire Engineer.

A CRONIFICAÇÃO NOS SERVIÇOS SUBSTITUTIVOS NA REDE DE SAÚDE MENTAL DE NATAL/RN

Brazilian Psychiatry Reform, through Psychosocial Care Strategy, has intended to build insane people care practices from community care services which contemplates the subjects complete lives. However, to change the traditional care ways demands the facing of a series of epistemological, political and cultural obstacles. One of the current challenges deals with patients aggravation processes, with management ways, with devices and with professionals, as well as with the assistance network. The purpose of this thesis was to investigate how these aggravation processes has been constituted in Natal mental healthcare network, understanding its effects in the work teams and patients. Theoretical and methodological perspective used was Institutional analysis was, subsidizing the usage of concept-tools as the implication analysis, selfmanagement and self-analysis, and restitution. The research was carried out at the Natal East Sanitary District Mental Healthcare Clinic, with the participation of technicians and patients. The research procedures were: literature and document research on the attendance and the analyzed theme; attendance registers analysis; participating observation of the institutional routine for three months and field log entries; talking groups, one with the team and one with the patients. Two main discussion points are shown: 1. The mental healthcare clinic organization logic and the intersector politics; 2. The work and management processes developed at the mental healthcare clinic. The analysis show diversity in the attended demands in the service, which has favored the patients aggravation, this device and the substitute network processes. The work processes are apart from the political sphere and from the managements processes. In this sense, we show the need to reevaluate the clinic device as well as the management models adopted in the Brazilian Psychiatry Reform context

Dois testes de imageamento com GPR em problemas de controle ambiental em regiões tropicais: migração de dunas e localização de dutos de óleo enterrados

Because the penetration depth of Ground Penetrating Radar (GPR) signals is very limited in high conductive soils, the usefullness of this method in tropical regions is not yet completly known. The main objective of this researh is to test the usefullness of the method in Brazil. Two typical problems where GPR has been used in Europe and North American were choosed for this test: the first one is to characterize the internal structures of a sand body and the second problem is the localization of old buried pipes lines. The first test was done near the city of São Bento do Norte, in the northern coast of Rio Grande do Norte state, NE Brazil. In this region, there is a sand dune that is migrating very fast in the direction of adjacent settling areas. To characterize the internal structure of the dune and its relationship to the prevailing wind direction, as a preliminary step to understand the dune migration, GPR profiles using the 400 MHz frequency were performed in E-W, N-S, NE-SW, and SE-NW directions over the sand dune intersecting at the top of the dune. The practical resolution of the GPR data is around 30 cm; this was sufficient to distinguish individual foresets inside the dune. After applying the elevation correction to the data, we identified that dips of bedding structures are smallest for the N-S profile, which is perpendicular to the dominant wind direction, largest for the E-W profile, and intermediate for the SW-NE and SE-NW profiles. Foresets in the E-W profile dip with angles varying from 2 to 6 degrees. In the E-W profile, the water table and a horizontal truncation interface separating two generations of dunes were identified, as well as an abrupt directional change in the foreset patterns associated to a lateral contact between two dune generations, the older one extending to the west. The used high frequency of 400 Mhz does not allow a penetration deep enough to map completely these internal contacts. The second test was done near Estreito, a small town near Carnaúbais city, also in Rio Grande do Norte state. In this locality, there are several old pipe lines buried in area covered by plantations where digging should be minimized. Several GPR profiles using the 400 and 200 MHz frequency were performed trying to intercept perpendicularly the possible pipe lines. Because of the high conductivity of the soil, the raw original data can hardly be use to identify the pipe lines. However, after an adequate processing over the 200 MHz profiles, six pipe lines were identified. As a global result of the tests, GPR can be very usefull if the conductivity of the ground is low or, in the case of medium conductivities of the soils, if adequate processing is performed

O cuidado em saúde no ciclo gravídico-puerperal sob a perspectiva de usuárias de serviços públicos

O objetivo do trabalho foi apreender as representações sociais de puérperas sobre o cuidado em saúde no período pré-natal, no parto e no puerpério, em um contexto regional de serviços públicos de saúde do interior paulista. Seguindo a abordagem de pesquisa qualitativa, os dados foram colhidos por meio de entrevistas semi-estruturadas, realizadas em 2004, e organizados segundo o método do Discurso do Sujeito Coletivo, tendo o Programa de Humanização do Pré-natal e Nascimento (PHPN) como referencial teórico para discussão dos resultados. A perspectiva das puérperas sobre o cuidado em saúde no ciclo gravídico-puerperal evidenciou a importância das relações interpessoais, a essencialidade da qualidade técnica do atendimento e a propriedade da percepção de que o sujeito da atenção é a mulher e, como tal, dela deve participar efetivamente. Conclui-se que as diretrizes do PHPN devem ser incorporadas de forma mais ampla nas práticas de saúde voltadas à mulher, recomendando-se a adoção de indicadores específicos para avaliação das dimensões do cuidado evidenciadas por este estudo.

A produção capitalista do espaço: os loteamentos, os condomínios fechados e o seu papel na formação do Bairro de Nova Parnamirim/Parnamirim-RN

This work exposed desired to investigate the function of evolution of closed allotment, of market of the earth and of forms of extraction of the lace of earth, in the processes capitalist production of urban space in Nova Parnamirim, community of Parnamirim/RN. This tendentious urbanization were marked for an expressive increase of number of horizontal and vertical closed residences joint ownership concerning at social groups more privileged financial position. Go after, set off, a temporal investigation, based in the forms of appropriation of space in the middle intermediate by action of the several producers agent of capitalist capital. This way, make necessary understand the past of local structure earth, in order that to make possible analyze the beginning of the process. Not enough, appealed the publics institutions as immobile notary s office and secretary municipal for to collect the more important information, and in the field through of application of formulary together the population of ward, in order that of examine the motivation of residential establishment inside. Make this, confirmed that the actual spatial organization of ward of Nova Parnamirim started of two allotments: the Vale do Pitimbú Park and Eucaliptos Park, both divided in several little allotments. Before of begin the ward, allotments reproduced set off from that native has been consigned during the 80, 90 decade s and begin the actual century, resigning a complicated urban structure earth, dynamized by exploration of a promising residential area. Leashed of this, confirmed the installation of logic of segregation and auto-segregation conducted by an immobile market which exclude the poor class and absorb rich class, motivate by perspective of obtaining of urban lace of earth by immobile promoter. However, perceived that the growth this market was promoted by migration of groups of capital, interior of state and others regions of country. Not distant, horizontal and vertical closed residences represent production forms of a new form of residence, corresponding the pattern architectonic as socioeconomics, strengthened by ideal of security, quality of life, necessity of reclusion and of proximity of Natal. Is in the capital which this individual found possibilities of attend satisfactory minimum of yours necessity in relation a consumption of bens and specialized and specifics services. Before this qualitative perceive that the social and spacial differential of Nova Parnamirim was the responsible by soil and habitation valorization of ward, that reinforce the promotion of segregation and of auto-segregation, and consequently, of capitalist reproduction of urban space

O uso do território pelos serviços privados de saúde em Natal/RN

Nowadays we can observe in Natal city, the development of the structure and the health s private service. However, the spatial distribution of these services will be marked by an uneven distribution on the places, what will be in according with the conditions offered by the same in each historical period. Accordingly, the objective of this job is analyze the use of the territory by the health s private service and the dynamics that promotes in Natal city in the technical scientific information period. Thus, seeking to search this goal, realized literature, documentary, empirical, considering the process of development and the spatial distribution of the health s private service in the city. From a topology we can observe that prevails in the city a service s concentration at all levels of complexity in only a few neighborhoods, being Tirol and Petrópolis, which are neighborhoods that have high densities of engineer system, bigger fluidity, and the best level salaries of the city, which present a greater number of these establishments. However, equal this concentration has occurred a dispersion of these services to other neighborhoods, as for example Lagoa Nova which is presenting the same attractiveness in the view of attributes territorial, begins to protect services presenting the same profile like the firsts. However, the city has a significant demand to this kind of service found in these neighborhoods, some events provided the emergency of another type of market of health s private service, that are those created to attend guests with a lower purchasing power, which will have their establishments in the same way selectively distributed in some areas of the city, which will not be the same pursued by the other, showing how selective is the installation of an enterprise guide by the logic of capitalism reproduction. So, the imperative of spatial selectivity presented by the health s private sector exposes an use of the differential territory for these services

Detecção do risco de suicídio nos serviços de emergência psiquiátrica

OBJETIVO: Auxiliar o profissional de saúde na identificação dos fatores de risco e de proteção, e no manejo de pacientes com risco de suicídio, por meio de entrevista clinica, no contexto de emergência médica. MÉTODO: Revisão seletiva da literatura para identificar achados clínicos relevantes e ilustrativos. RESULTADO: A entrevista clinica é o melhor método para avaliar o risco suicida e tem dois objetivos: 1) apoio emocional e de estabelecimento de vínculo; 2) coleta de informações. Existe um número considerável de informações a serem coletadas durante a entrevista: fatores de risco e proteção (predisponentes e precipitantes), dados epidemiológicos, caracterização do ato, aspectos psicodinâmicos, antecedentes pessoais e familiares, modelos de identificação, dados sobre saúde física e rede de apoio social. Dificuldades ao longo da entrevista serão encontradas, mas com conhecimento e treinamento adequado, o profissional poderá abordar e ajudar adequadamente o paciente. Embora várias escalas tenham sido propostas, nenhuma delas demonstrou eficiência para a detecção de risco de suicídio. CONCLUSÃO: Não há como prever quem cometerá suicídio, mas é possível avaliar o risco individual que cada paciente apresenta, tendo em vista a investigação detalhada e empática da entrevista clinica. Impedir que o paciente venha a se matar é regra preliminar e fundamental.

QualiAB: desenvolvimento e validação de uma metodologia de avaliação de serviços de atenção básica

Este artigo apresenta o desenvolvimento, validação e utilização de uma metodologia de avaliação da qualidade dos serviços de atenção primária do Sistema Único de Saúde (SUS), o Questionário de Avaliação da Qualidade de Serviços de Atenção Básica (QualiAB). Destina-se aos serviços de atenção básica, organizados segundo diferentes modelos de atenção, incluindo a Saúde da Família. Contém 50 indicadores sobre oferta e organização do trabalho assistencial e programático e 15 sobre gerenciamento, na forma de questões de múltipla escolha, autorespondidas via web pela equipe local do serviço. Confere a cada resposta valor zero, um ou dois; a média geral atribui ao serviço um grau de qualidade expresso pela distância do melhor padrão correspondente à média dois. Foi construído por processo de consenso interativo, que incluiu metodologias qualitativas, teste-piloto, aplicação em 127 serviços, validação de construto e confiabilidade. Respondido, em 2007, por 598 (92%) dos serviços de 115 municípios paulistas, mostrou bom poder para discriminar níveis de qualidade. Adotado em 2010 como parte de um programa de apoio à Atenção Básica da Secretaria de Estado da Saúde de São Paulo, foi respondido por 95% (2.735) dos serviços de 586 municípios (90,8% do Estado). Os resultados foram encaminhados aos municípios. O QualiAB fornece uma avaliação válida, simples e com a possibilidade de retorno imediato para gerentes e profissionais. Mostrou factibilidade, aceitabilidade, bom poder de discriminação e utilidade para auxiliar a gestão da rede de atenção básica do SUS em São Paulo. A experiência indica aplicabilidade nas redes de atenção básica do Brasil.
