Ações educativas com portadores de diabetes Mellitus através da educação popular em saúde

Popular Health Education in its emancipatory dimension refers to individuals and groups to exchange knowledge and experiences, allowing them to associate health to the outcomes of their living conditions. Under this view, health workers and health users are subjects of the educative process. Thus, this study aims to identify the key clinical and socio sanitary attributes and promote educational activities with patients with Diabetes Mellitus (DM) in a Family Health Care Unit of the Western Sanitary District, in the city of Natal / RN. It is an action research which uses the references of the Theory of Liberating Education, which is based on a problem-solving pedagogy and that values dialogue in the process of understanding oneself and the world. Thirty-six diabetics, who are residents of the area covered by the health care unit, and thirty health workers participated in the survey. Each group had an average of twelve participants, and the meetings took place at the Unit´s hall, using conversation wheels, group dynamics, life narratives, experiences telling, movie exhibition and discussions, music, knowledge telling, desires, limitations, beliefs and values socially constructed. Data collection took place during the second half of two thousand and thirteen through Free Word Association Technique (FWAT), recordings of conversation wheels, participative observation, group dynamics, testimonies, questionnaires, life narratives and photographs. The empirical material was organized and subjected to three analyzes: thematic content (Bardin), textual statistics analysis by software IRAMUTEQ (Ratinaud), and photographic analysis (Edmund Feldman). The data analyses originated words, expressions, categories, themes and creative situations showing that popular health education is in process of construction, but still very incipient in primary care. The National Policy on Popular Health Education shows us the necessary ways for the transformation of health practices and the build of a more shared and solidary society. The meetings could be place to reverse that normative logic that has been happening over the years in primary care, but that by itself is not enough. It is possible to conclude that the use of active practices, increasing of listening and training on Popular Health Education will enable changes in the scenario where users and health workers deal with diabetes mellitus. Thus we see the popular health education is being timidly incorporated to the educational process of the subjects involved in this study, and far away from the principles of participation, organization of political work, increase opportunities for dialogue, respect, solidarity and tolerance among different actors involved in addressing the health problems that are fundamental to the improvement in building healthy practices of primary care

A humanização da saúde no cotidiano de usuários da estrategia saúde da família

This research assumes that for changes in health practices directed to an integral care, is crucial humanization, participation and autonomy of service users. In this sense, the research had investigated the issue of humanization involving users of the Family Health Strategy (FHS) in city of Mossoró, having as objectives: to analyze the perceptions of users on humanization in the production of health care in daily of Family Health Strategy, from these perceptions, identify elements featuring humanized and non-humanized in everyday practices related to production of health care; relate perceptions of users about humanization with the notions of extended clinic and social participation present in the National Humanization Policy (NHP); identify difficulties and potentialities in the production of health care from the perspective of humanization. It was a qualitative approach to data collection and it was used the methodology of Network Analysis of Everyday Life (NAEL), which allowed the questioning of health practices through an interactive discussion involving participants subjected. The analysis of data through the technique of content thematic analysis was performed and the results were interpreted related the Extended Clinic references and the users participation, related with the Gift Theory discussed by Marcel Mauss. The results indicated senses humanization linked to affection, reciprocity and honesty, highlighting as essential to humanized practices the trust, bonding, listening, dialogue and accountability. Were also mentioned other elements related to the organization of health services such as access and good functioning of the health services. The difficulties and potentialities show structural deficiencies of the health system and changes in the labor process. The participation of users deconstructing and reconstructing concepts remainder humanization in the production of health care is a key factor for the sedimentation of what is proposed in the HNP. Using the privileged space of the FHE to create more active people and understanding their needs and demands, is possible path to build a participative management

GT4CCI: uma abordagem baseada em grounded theory para a identificação de interesses transversais em documentos de requisitos

When crosscutting concerns identification is performed from the beginning of development, on the activities involved in requirements engineering, there are many gains in terms of quality, cost and efficiency throughout the lifecycle of software development. This early identification supports the evolution of requirements, detects possible flaws in the requirements specification, improves traceability among requirements, provides better software modularity and prevents possible rework. However, despite these several advantages, the crosscutting concerns identification over requirements engineering faces several difficulties such as the lack of systematization and tools that support it. Furthermore, it is difficult to justify why some concerns are identified as crosscutting or not, since this identification is, most often, made without any methodology that systematizes and bases it. In this context, this paper proposes an approach based on Grounded Theory, called GT4CCI, for systematizing and basing the process of identifying crosscutting concerns in the initial stages of the software development process in the requirements document. Grounded Theory is a renowned methodology for qualitative analysis of data. Through the use of GT4CCI it is possible to better understand, track and document concerns, adding gains in terms of quality, reliability and modularity of the entire lifecycle of software

Análise da rede política do turismo brasileiro.

The dissertation examines the influence of relationships among actors from Brazilian Tourism Political Network who compose the National Council of Tourism in the drafting of the National Tourism Plans (PNT) - PNTs 2003/2007 and 2007/2010, focusing on two main types of interaction: cooperation and information exchange. Therefore, the study departed from the understanding that the concept of tourism as a human phenomenon is configured as an essential conceptual basis for the development, implementation and analysis of public policies. The application of Network Theory and Social Network Analysis serves as an analytical tool, in addition, the use of concepts of Policy Networks enabled to interpret, in distinct aspects, the social reality of tourism in a more precise and detailed way. The study had a cross-sectional with a longitudinal perspective and case study was adopted, thus enabling to apply the model of social network analysis and qualitative approach. Through the survey conducted, it was found that the drafting process of National Tourism Plans was the result of the interaction of a complex network of actors from public and private initiatives, who compose the National Council of Tourism, and that their power of influence came out simultaneously, but not symmetrically, for both their performance/intervention in the meetings, and the possession of economic and organizational resources. Hence, the establishment of partnerships and information exchanges among the actors were underlying to the PNT drafting process, both in problems perception and insertion in the government agenda, as in making proposals to solve them, thus guiding the construction of large programs and programs contained in both investigated plans.

Family visitors and companions of hospitalized elderly and adults: analysis of the experience from the perspective of the nursing working process

Trata-se de estudo qualitativo, utilizando-se como referencial metodológico a Grounded Theory e como referencial teórico o Processo de Trabalho em Enfermagem, para compreender o papel assumido pelo enfermeiro perante as normas e rotinas hospitalares, relativas aos familiares visitantes e acompanhantes de adultos e idosos internados em um Hospital Universitário. A análise dos dados permitiu a identificação do tema: definindo-se a modalidade de apoio familiar durante a hospitalização, que reúne duas categorias principais: tornando-se familiar visitante e tornando-se familiar acompanhante. Por meio da análise, pôde-se aprofundar a compreensão do quanto as regras estabelecidas, com o objetivo de disciplinar e tornar eficiente o trabalho desenvolvido no hospital, podem explicitar o desprovimento de autonomia no processo de trabalho, para modificar as relações nesse contexto e o quanto a apropriação do familiar como parte da equipe de saúde, está distante de ser pensada no concreto das instituições.

The aggregation process in tetraethoxysilane-derived sonogels as an analogy to the critical phenomenon

The structural evolution in silica sols prepared from tetraethoxysilane (TEOS) sonohydrolysis was studied 'in situ' using small-angle x-ray scattering (SAXS). The structure of the gelling system can be reasonably well described by a correlation function given by gamma(r) similar to (1/R(2))(1/r) exp(- r/xi), where xi is the structure correlation length and R is a chain persistence length, as an analogy to the Ornstein-Zernike theory in describing critical phenomenon. This approach is also expected for the scattering from some linear and branched molecules as polydisperse coils of linear chains and random f-functional branched polycondensates. The characteristic length. grows following an approximate power law with time t as xi similar to t(1) (with the exponent quite close to 1) while R remains undetermined but with a constant value, except at the beginning of the process in which the growth of. is slower and R increases by only about 15% with respect to the value of the initial sol. The structural evolution with time is compatible with an aggregation process by a phase separation by coarsening. The mechanism of growth seems to be faster than those typically observed for pure diffusion controlled cluster-cluster aggregation. This suggests that physical forces (hydrothermal forces) could be actuating together with diffusion in the gelling process of this system. The data apparently do not support a spinodal decomposition mechanism, at least when starting from the initial stable acid sol studied here.

Multivariate analysis of stable isotope data in the traceability process for birds

A análise isotópica tem se mostrado uma ferramenta de suma importância ao processo de rastreabilidade, no entanto, existem divergências nas análises estatísticas dos resultados, uma vez que os dados são dependentes e advindos de vários elementos químicos tais como Carbono, Hidrogênio, Oxigênio, Nitrogênio e Enxofre (CHON'S). Com o intuito de estabelecer a análise propícia para os dados de rastreabilidade em aves pela técnica de isótopos estáveis e avaliar a necessidade da análise conjunta das variáveis, foram usados dados de carbono-13 e de nitrogênio-15 de ovos (albúmen + gema) de poedeiras e músculo peitoral de frangos de corte, os quais foram submetidos à análise estatística univariada (Anova e complementada pelo teste de Tukey) e multivariada (Manova e Discriminante). Os dados foram analisados no software Minitab 16, e os resultados, consolidados na teoria, confirmam a necessidade de análise multivariada, mostrando também que a análise discriminante esclarece as dúvidas apresentadas nos resultados de outros métodos de análise comparados nesta pesquisa.

Non-Hermitian multichannel theory of ultracold collisions modified by intense light fields tuned to the red of the trapping transition

We develop a systematic scheme to treat binary collisions between ultracold atoms in the presence of a strong laser field, tuned to the red of the trapping transition. We assume that the Rabi frequency is much less than the spacing between adjacent bound-state resonances, In this approach we neglect fine and hyperfine structures, but consider fully the three-dimensional aspects of the scattering process, up to the partial d wave. We apply the scheme to calculate the S matrix elements up to the second order in the ratio between the Rabi frequency and the laser detuning, We also obtain, fur this simplified multichannel model, the asymmetric line shapes of photoassociation spectroscopy, and the modification of the scattering length due to the light field at low, but finite, entrance kinetic energy. We emphasize that the present calculations can be generalized to treat more realistic models, and suggest how to carry out a thorough numerical comparison to this semianalytic theory.

Product development process: Using real options for assessments and to support the decision-making at decision gates

Enterprises need continuous product development activities to remain competitive in the marketplace. Their product development process (PDP) must manage stakeholders' needs - technical, financial, legal, and environmental aspects, customer requirements, Corporate strategy, etc. -, being a multidisciplinary and strategic issue. An approach to use real option to support the decision-making process at PDP phases in taken. The real option valuation method is often presented as an alternative to the conventional net present value (NPV) approach. It is based on the same principals of financial options: the right to buy or sell financial values (mostly stocks) at a predetermined price, with no obligation to do so. In PDP, a multi-period approach that takes into account the flexibility of, for instance, being able to postpone prototyping and design decisions, waiting for more information about technologies, customer acceptance, funding, etc. In the present article, the state of the art of real options theory is prospected and a model to use the real options in PDP is proposed, so that financial aspects can be properly considered at each project phase of the product development. Conclusion is that such model can provide more robustness to the decisions processes within PDP.

Language policy in Brazil: Monolingualism and linguistic prejudice

The purpose of this article is to analyse the linguistic situation in Brazil and to discuss the relationship between Portuguese and the 200 other languages, about 170 indigenous, spoken in the country. It focuses on three points: the historical process of language unification, recent official language policy initiatives, and linguistic prejudice. I examine two manifestations of linguistic prejudice, one against external elements, and the other against supposedly inferior internal elements, pointing out to a common origin: the myth that the Portuguese language in Brazil is characterised by an astonishing unity. © 2004 Kluwer Academic Publishers.

A synthetic control chart for monitoring the process mean and variance

Purpose - The aim of this paper is to present a synthetic chart based on the non-central chi-square statistic that is operationally simpler and more effective than the joint X̄ and R chart in detecting assignable cause(s). This chart will assist in identifying which (mean or variance) changed due to the occurrence of the assignable causes. Design/methodology/approach - The approach used is based on the non-central chi-square statistic and the steady-state average run length (ARL) of the developed chart is evaluated using a Markov chain model. Findings - The proposed chart always detects process disturbances faster than the joint X̄ and R charts. The developed chart can monitor the process instead of looking at two charts separately. Originality/value - The most important advantage of using the proposed chart is that practitioners can monitor the process by looking at only one chart instead of looking at two charts separately. © Emerald Group Publishing Limted.

Enterprise systems modeling: The ERP5 development process

The design and implementation of an ERP system involves capturing the information necessary for implementing the system's structure and behavior that support enterprise management. This process should start on the enterprise modeling level and finish at the coding level, going down through different abstraction layers. For the case of Free/Open Source ERP, the lack of proper modeling methods and tools jeopardizes the advantages of source code availability. Moreover, the distributed, decentralized decision-making, and source-code driven development culture of open source communities, generally doesn't rely on methods for modeling the higher abstraction levels necessary for an ERP solution. The aim of this paper is to present a model driven development process for the open source ERP ERP5. The proposed process covers the different abstraction levels involved, taking into account well established standards and common practices, as well as new approaches, by supplying Enterprise, Requirements, Analysis, Design, and Implementation workflows.
