Avaliação das ações do Núcleo de Apoio à Saúde da Família (NASF) em Macaíba/RN

This research evaluated the contribution of the Support Center for Family Health (SCFH) in relation to its effect on the Family Health Units through perception of the Family Health Strategy (FHS) and SCFH professionals, in addition to the satisfaction of users in relation to that role. Data were collected in the public health services of the city of Macaíba-RN in 2012, through semi-structured questionnaire and non participant systematic observation and it counted as investigated subjects 272 individuals (60 FHS professionals, 12 SCFH professionals and 200 users representatives of 20 units). For analysis of the responses of the opened questions was used categorization process and, in relation to the observational method, that was based on checking the space organization, the characteristics of the participating subjects and the specific set of activities performed by SCFH teams through an observation guide. The results point to a good acceptance of the SCFH teams role by most FHS professionals who reported active participation in the health units routine, its integration activities to the FHS teams with resolving based health promotion actions. Regarding the SCFH professionals, they also reported positive contribution by participating actively in the units routine with integrated activities to the ESF teams and developing resolute actions. For users, the SCFH brought assurance services with better access to specialized, resolving and welcoming care. Systematic observation ratified data obtained by questionnaire. It was perceived the need to implement actions related to man`s health, to invest in expanding the number of the SCFH teams, the greater supply of medications, improving the regulatory process and planning together as a key strategy to promote a more effective integration between teams SCFH / FHS

Fatores socioeconômicos contextuais associados à condição bucal de adolescentes no Brasil

Many surveys are conducted comparing oral health conditions with individual variables, such as socioeconomic and demographic factors. However, in the same way that individuals differ among themselves, the groups also have their own characteristics and the effects of this differentiation must be researched. Brazil, despite being one of the major economic powers of the world and shows an improvement in the average value of its health indicators, is also one of the most unequal and remains among the countries with the greatest health inequities. The purpose of this study was to investigate the importance of social determinants on the contextual level oral health among Brazilian adolescents, population not much researched by the literature. The research was made using an ecological approach in order to identify possible inequalities between cities and capitals. Using data from SBBrasil 2010 it was evaluated less common outcomes (loss of first molar, dental care index and T-Health) which provide information on the degree of morbidity of caries and health level of dental tissues, in addition to analyze the related services. The association of these oral health indicators with socioeconomic factors such as income, employment, education and inequality, collected from Census 2010, was analyzed by simple and multiple linear regressions. The study included the 27 state capitals and four clusters representing the municipalities of the country. It was possible to see better access to services in locations with better income distribution. However, the strong association of contextual factors related to poverty, low levels of education and poor housing and jobs with poorer levels of oral health in adolescents seems to overshadow the effects of income inequalities on dental caries in the country. In some locations, particularly within the North and Northeast, whichever one keeps dentistry mutilating, whose effects are already noticeable in its adolescent population. Access to restorative services in Brazil remains limited and unequal. The results of this study highlight the inequities in oral health in the country and show the need of the inclusion of new perspectives on the traditional approach of Preventive Dentistry and education models in Dentistry. Tackling health inequalities in oral health in the country requires the cooperation of various actors involved in the process and the inclusion of oral health in the context of overall health. The social determinants approach, as well as evaluating the distribution of oral diseases in the country and its inclusion in the context of overall health, should guide the implementation of programs and oral health practices in order to contribute to the reduction of inequalities

Distribuição do sistema radicular do porta-enxerto Coquinho sob copa da mangueira cv. Haden

Para o manejo adequado de uma cultura, especialmente frutífera perene, torna-se importante o conhecimento de vários fatores agronômicos, entre os quais o desenvolvimento e a distribuição do sistema radicular. Este trabalho objetivou avaliar a distribuição do sistema radicular do porta-enxerto coquinho sob copa da mangueira cultivar Haden. O estudo foi realizado de março/2005 a maio/2007 em solo argiloso, Latossolo Vermelho distrófico, sob vegetação de cerrado, em pomar implantado em 1992, espaçamento de 10 x 10 m, na Fazenda de Ensino, Pesquisa e Extensão da Faculdade de Engenharia/Unesp/Ilha Solteira, localizada no Município de Selvíria-MS. Os tratamentos utilizados foram: plantas testemunhas, sem aplicação de calcário, e plantas que receberam 3,1 t de calcário ha-1. Avaliou-se o sistema radicular, coletando-se amostras de solo e raízes nas profundidades de 0,0-0,20; 0,20-0,40; 0,40-0,60; 0,60-0,80 e 0,80 a 1,0 m e nas distâncias do tronco de 0,83; 2,49; 4,15 m, classificando as raízes em < 2; 2-5; 5-10 e >10 mm de diâmetro. As raízes de absorção de maior ocorrência foram as de diâmetro menor do que 2 mm nos dois tratamentos. A maior concentração de raízes de absorção ocorreu na faixa compreendida entre 0,0 e 1,66 m do tronco e ao longo do perfil analisado, de 0,0 a 1,0 m de profundidade. A maior concentração de raízes de absorção localizou-se até 0,4 m de profundidade. As plantas que receberam calcário apresentaram aumento de 15,73% de raízes de absorção em relação à testemunha.

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

Extensão universitária: concepções e ações na UFRN sob a temática direitos humanos e justiça no período 2008 a 2010

This paper concerns a study on the University Extension, by reference to the research extension activities under the theme human rights and justice, developed in the period 2008 to 2010 in UFRN. To do so, it tried to learn the concepts of extension in Brazil from the 1970s until the 2000s in contemporary times. This study considered the neoliberal social context of the University, dominated by educational policies focusing on the hegemony of liberal ideas about society, reflecting the great advances of capital on the organization of workers in the last decades and intensified in the 1990s. This research was guided by two great motivations: the opportunity to apprehend a way to enforce the commitment of public institutions of higher education to the disadvantaged sections of society and what role the university extension space plays as a socially committed public university. The general aim of this study is to identify inside the university extension education what does it mean for practitioners and extension activities and what results it produces to society and to the academic training of future professional citizens in the current neoliberal context. The research has been developed from an analytical and critical approach based on quantitative and qualitative data, using observation techniques and semi-structured interviews. We sought to investigate and understand the social reality, the main object of this work, with an interest in identifying the need for a new teaching/learning process and for a new university practice, in order to effectively improve an advanced academic formation. For this, some interviews have been conducted with teachers, students and the external community involved in extension actions in the period defined by the work, i.e., from 2008 to 2010. In this stage, it was observed that the academic work of university extension is essential to civic education. It was recognized too as a privileged space where university fulfills its social commitment towards society, as long as it joins scientific and popular knowledge having in view a new science and a new social order

Uma Análise Comparativa entre Sistemas de Combinação de Classificadores com Distribuição Vertical dos Dados

In systems that combine the outputs of classification methods (combination systems), such as ensembles and multi-agent systems, one of the main constraints is that the base components (classifiers or agents) should be diverse among themselves. In other words, there is clearly no accuracy gain in a system that is composed of a set of identical base components. One way of increasing diversity is through the use of feature selection or data distribution methods in combination systems. In this work, an investigation of the impact of using data distribution methods among the components of combination systems will be performed. In this investigation, different methods of data distribution will be used and an analysis of the combination systems, using several different configurations, will be performed. As a result of this analysis, it is aimed to detect which combination systems are more suitable to use feature distribution among the components

Uso de replicação móvel para distribuição de vídeo digital em redes de computadores

A maioria da soluções apresentadas como candidatas à implementação de serviços de distribuição de áudio e vídeo, têm sido projetadas levando-se em consideração determinadas condições de infra-estrutura, formato dos fluxos de vídeo a serem transmitidos, ou ainda os tipos de clientes que serão atendidos pelo serviço. Aplicações que utilizam serviços de distribuição de vídeo normalmente precisam lidar com grandes oscilações na demanda pelo serviço devido a entrada e saída de usuários do serviço. Com exemplo, basta observar a enorme variação nos níveis de audiência de programas de televisão. Este comportamento coloca um importante requisito para esta classe de sistemas distribuídos: a capacidade de reconfiguração como conseqüência de variações na demanda. Esta dissertação apresenta um estudo que envolveu o uso de agentes móveis para implementar os servidores de um serviço de distribuição de vídeo denominada DynaVideo. Uma das principais características deste serviço é a capacidade de ajustar sua configuração em conseqüência de variações na demanda. Como os servidores DynaVideo podem replicar-se e são implementados como código móvel, seu posicionamento pode ser otimizado para atender uma dada demanda e, como conseqüência, a configuração do serviço pode ser ajustada para minimizar o consumo de recursos necessários para distribuir vídeo para seus usuários. A principal contribuição desta dissertação foi provar a viabilidade do conceito de servidores implementados como agentes móveis Java baseados no ambiente de desenvolvimento de software Aglet.

Avalição de reusabilidade de aplicações web baseadas em frameworks orientados a ações e a componentes: estudo de Caso sobre os Frameworks Apache Struts e JavaServer Faces

Over the years the use of application frameworks designed for the View and Controller layers of MVC architectural pattern adapted to web applications has become very popular. These frameworks are classified into Actions Oriented and Components Oriented , according to the solution strategy adopted by the tools. The choice of such strategy leads the system architecture design to acquire non-functional characteristics caused by the way the framework influences the developer to implement the system. The components reusability is one of those characteristics and plays a very important role for development activities such as system evolution and maintenance. The work of this dissertation consists to analyze of how the reusability could be influenced by the Web frameworks usage. To accomplish this, small academic management applications were developed using the latest versions of Apache Struts and JavaServer Faces frameworks, the main representatives of Java plataform Web frameworks of. For this assessment was used a software quality model that associates internal attributes, which can be measured objectively, to the characteristics in question. These attributes and metrics defined for the model were based on some work related discussed in the document

Algorítmo evolucionário para a distribuição de produtos de petróleo por redes de polidutos

The distribution of petroleum products through pipeline networks is an important problem that arises in production planning of refineries. It consists in determining what will be done in each production stage given a time horizon, concerning the distribution of products from source nodes to demand nodes, passing through intermediate nodes. Constraints concerning storage limits, delivering time, sources availability, limits on sending or receiving, among others, have to be satisfied. This problem can be viewed as a biobjective problem that aims at minimizing the time needed to for transporting the set of packages through the network and the successive transmission of different products in the same pipe is called fragmentation. This work are developed three algorithms that are applied to this problem: the first algorithm is discrete and is based on Particle Swarm Optimization (PSO), with local search procedures and path-relinking proposed as velocity operators, the second and the third algorithms deal of two versions based on the Non-dominated Sorting Genetic Algorithm II (NSGA-II). The proposed algorithms are compared to other approaches for the same problem, in terms of the solution quality and computational time spent, so that the efficiency of the developed methods can be evaluated

Uma abordagem através de algoritmos transgenéticos para o problema da configuração do traçado de uma rede de distribuição de gás natural

Este trabalho apresenta um algoritmo transgenético híbrido para a solução de um Problema de Configuração de uma Rede de Distribuição de Gás Natural. O problema da configuração dessas redes requer a definição de um traçado por onde os dutos devem ser colocados para atender aos clientes. É estudada neste trabalho uma maneira de conectar os clientes em uma rede com arquitetura em forma de árvore. O objetivo é minimizar o custo de construção da rede, mesmo que para isso alguns clientes que não proporcionam lucros deixem de ser atendidos. Esse problema pode ser formulado computacionalmente através do Problema de Steiner com Prêmios. Este é um problema de otimização combinatória da classe dos NPÁrduos. Este trabalho apresenta um algoritmo heurístico para a solução do problema. A abordagem utilizada é chamada de Algoritmos Transgenéticos, que se enquadram na categoria dos algoritmos evolucionários. Para a geração de soluções inicias é utilizado um algoritmo primaldual, e pathrelinking é usado como intensificador

Genética e biologia reprodutiva de vriesea minarum (Bromeliaceae): em busca de estratégias de conservação no quadrilátero ferrífero, minas gerais

Vriesea minarum is a rupiculous bromeliad species, with naturally fragmented populations, restricted to the Iron Quadrangle, Minas Gerais, Brazil. It is a threatened species, which is suffering from habitat loss due to the growth of cities and mining activities. The knowledge of genetic variability in plant populations is one of the main branches of conservation genetics, linking genetic data to conservation strategies while the knowledge about plant reproductive biology can aid in understanding key aspects of their life story, as well as in the comprehension of their distribution and survival strategies. Thus, the study of diversity, richness, and genetic structure, as well as the reproductive biology of populations of V. minarum can contribute to the development of conservation actions. Chapter 1 presents the transferability of 14 microsatellite loci for V. minarum. Among the results of this chapter, we highlight the successful transferability of 10 microsatellite loci described for other species of Bromeliaceae, all of which are polymorphic. In Chapter 2, we present the genetic analyses of 12 populations of V. minarum that are distributed throughout the Iron Quadrangle. We used the 10 microsatellite loci tested in Chapter 1. The results show a low population structuring (Fst = 0.088), but with different values of genetic richness (mean = 2.566) and gene diversity (mean = 0.635) for all populations; and a high inbreeding coefficient (Gis = 0.376). These may be the result of pollinators action and/or efficient seed dispersal, thus allowing a high connectivity among populations of naturally fragmented outcrops. The reproductive biology and floral morphology of a population of V. minarum, located in the Parque Estadual da Serra do Rola-Moça, are studied in Chapter 3. This reserve is the only public environmental protection area where the species occurs. As a result of field experiments and observations, we found that the species has its flowering period from January to March, with flowers that last for two days and that it has a mixed pollination syndrome. It is primarily alogamous, but also has the capacity to be self-ferilized. It is expected that data obtained in chapters 1, 2 and 3 serve as basis for other studies with species from the ferruginous rocky fields, since until now, to our knowledge, there are no other survey of endemic species from the Iron Quadrangle, seeking to merge the genetic knowledge, with the data of the reproductive biology, with the ultimate aim of biodiversity conservation. Considering the great habitat loss for the species by mining, it becomes crucial to analyze the creation of new protected areas for its conservation
