O concreto e o simbólico no cotidiano da educação em saúde: práticas, representações e processo identitário dos agentes comunitários de saúde de João Pessoa PB

The present study is about an etnographic research based on the Theory of Social Representation and its complementary approach, the Theory of Central Core based on the bourdiesianos concepts of field and habitus , concerning that these concepts, articulated to the constructed social representation, may contribute to the study of social identities. Its aim is to acknowledge which identity references community health agents (CHA), agents from Community Health Agent Program (CHAP) and Family Health Program (FHP) from João Pessoa PB and which social representation is constructed by them towards health education. The study had the participation of 119 CHAs, from which 90,3 % were female and 9,7% were male. Since the identity is also built by the representation of others towards the group, 63 professionals of the FHP group (16 nurses, 16 nursing assistents, 12 doctors, 9 dentists, 6 dentistry office assistents, 4 coordinators, 1 psicologist and 1 receptionist) and 1 nurse from CHAP took part of the study, oficial documents from the Health Ministry were analyzed, verbal information from its representatives were also taken into consideration, as well as reports from the many benefitiaries of the CHA, CHAP and FHP. For data collecting, we used the combination of (a) Direct Observation and Participant Observation of the functioning micro-areas of the CHA at the Family Health Units, and the Union of the Agents; (b) Free-Association of words and expressions to stimulate the CHA , Health Education and Health ; (c) Questionnaire; (d) Interviews. The interviews were submitted to a thematic analysis of its topic. The free-association was analyzed taking in consideration the vèrgesiana proposal (a combination of the frequency and average order of evocation) which treatment enabled the identification of the central and peripheral systems of social representation towards health education and the community health agent. A test of central refutation, associated to the analysis of the indicated evocations as the most important, provided empirical evidence of social representation towards health education as orientation , prevention and hygiene , as well as the identity of CHA as supervisor , friend , help , important , and the link between the community and the Family Health Staff. Other professionals from CHAP, FHP and the Health Ministry share all of these representational contents, especially the concepts of friend and link , also shared by the community. A habitus towards the community health agents was identified, as a representation based on trust and friendship, which gives the professional a great importance towards the daily inconsistencies faced by the community

Campo educacional e representação social da formação docente :o olhar dos agentes

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

Ações dos agentes comunitários de saúde diante do usuário da estratégia saúde da família com estados depressivos no Município de Abaiara-CE-BR

Brazilian health public assistance is going through two Reforms, Sanitary and Psychiatric, and through these the assistance is guaranteed in the three levels: primary, secondary and tertiary. Thus, mental health assistance should be offered since preventive cares until the ones that demand larger technological apparatus. Programs like Health Community Agent's Program (HCAP) and Family Health Strategy (FHS), besides increasing the services coverage, have been making possible the system reorientation in the meaning of integrality, universalization and equity. Thus, united intervention of mental health team and FHS can offer several benefits to the population, providing assistance and follow-up to patients with mental disorder. It was aimed to assess health community agents facing the user of Family Health Strategy in depressive state. This quanti-qualitative study took place in the municipal district of Abaiara-CE. Semi-structured interview was applied with health community agents and Beck Depression Inventory with the users registered in Family Health Strategy. It was verified that among the 64 users interviewed, 12.5% didn't present symptoms of depression, 10.9% presented symptoms of light depression, 14.1% symptoms of moderate depression and 62.5% symptoms of serious depression. For the 22 health community agents interviewed, they all reported the existence of people with symptoms of depression in their personal micro-areas, being difficult to work with them, once the FHS team is not qualified to work with mental health problems. It was verified that the Municipal district doesn't have specialized professionals, making difficult the routing and treatment. Based on these results, it was concluded that in spite of the articulation of mental health with FHS is necessary and benefactor to the population, it still doesn't exist, worsening the situation, mainly in small Municipal districts, once they don't have mental health services. Thus, the population is exposed and without follow-up, which allows the identification of installed diseases and with gravity, like depression, because there are no prevention and control activities. It is recommended, due the extreme need, the elaboration and implantation of a mental health program in these municipal districts, articulated with FHS

Uso de agentes microbianos e químico para o controle de Meloidogyne incognita em soja

Nematoides de galhas constituem importante grupo de patógenos da cultura da soja e o manejo integrado é uma das principais medidas de controle que visam à redução de perdas econômicas. Neste trabalho foi avaliada a eficácia dos fungos Paecilomyces lilacinus (Thom.) Samsom e Pochonia chlamydosporia (Goddard) Zare & Gams (sinonímia Verticillium chlamydosporium), de um produto comercial à base de Bacillus sp. (Nemix) e do nematicida químico Aldicarb no controle de Meloidogyne incognita em soja, variedade M-SOY 6101. O experimento foi realizado em casa-de-vegetação no delineamento experimental de blocos casualizados com nove tratamentos (três produtos biológicos usados no tratamento de sementes com ou sem a aplicação em pós-emergência, Aldicarb aplicado apenas em pós-emergência e duas testemunhas) e quatro repetições. Aldicarb reduziu o número de ovos e de juvenis do nematoide. P. lilacinus foi o mais atuante dos agentes biológicos, favorecendo a manutenção da quantidade de matéria seca da raiz de soja e reduzindo o número de ovos. O produto Nemix e P. chlamydosporia somente tiveram ação efetiva na redução do número de ovos do nematoide. Com base nos resultados, foi possível concluir que o agente químico e os agentes biológicos avaliados neste trabalho tiveram moderada atividade no controle de M. incognita em soja.

Atenção à saúde mental na Estratégia Saúde da Família no Município de Parnamirim/RN: opinião dos profissionais, dos portadores de transtornos mentais e seus acompanhantes

This study aims to analyze and compare the opinion of professionals, managers and users about the mental health care in the Family Health Strategy (FHS). It is characterized as an Operations Research or Health System Research with a cross-sectional design and a descriptive quantitative nature. The study was developed from the application of the Opinion Measurement Scale allied to techniques of observation and structured interview in the city of Parnamirim / RN. The sample consists of 409 subjects, 209 professionals of the Family Health Strategy, 30 of the Oral Health Strategy, 19 of the Family Health Support Center, 24 directors of Basic Health Units, plus 68 users with mental disorders and 59 caregivers, respecting the ethical parameters of Resolution 196/96 of the National Health Council, trial registration number: CAAE 0003.0.051.000-11. Quantitative data were submitted to the Epi-info 3.5.2 for analysis. The network of mental health in Parnamirim involves the flow between the FHS, Psychosocial Care Centers, clinics and hospitals, having as main barriers the fragility of the referral and counter-referral system, of the municipal health conferences, of the FHS teams by the limitations in material and human resources as well as the population´s lack of acknowledge about the organization of the mental health network, issues that affect the integral attention. Even though the FHS professionals recognize the importance of their actions, they question their role in mental health care, experiencing difficulties in accessing psychiatric services (76.5%). Although most agree that the mentally ill is best treated in the family than in hospital (65.2%), the community health workers were the predominant category in the partial or total disagreement of this statement (40.8%), who is the professional in greater contact with the family. Nevertheless the caregivers miss the support of the FHS as the main focus of attention is on revenue control. The views of professionals, mental patients and caregivers converged in several statements, showing the main weaknesses to be focused by the mental health network of the city, as the perceptions that: (a) physical strength is needed to take care of mental patients for its tendency to aggression, requiring it to stay in the sanatorium for representing danger to society, (b) only a psychiatrist can help the person with emotional problems, (c) the user of alcohol and drugs does not necessarily develop mental illness, (d) the access barriers and doubts about the quality of psychiatric services, (e) caring of a mental health patient does not bring suffering to professionals. Therefore, the commitment to consensus building, monitoring and evaluation of the network are important mechanisms for an effective management system, reflecting in the importance of strengthening the health conferences and approximating different institutions. The results reinforce the importance of strengthening primary care through programs of continuing education focusing on the actions and functions of professionals in accordance with its competences and duties what contribute to the organization and response of mental health care, favoring user´s care and the promotion of family health

Efeito da adição de agentes tróficos na dieta de leitões desmamados sobre a estrutura e ultraestrutura do intestino delgado e sobre o desempenho

Foram estudados os efeitos da glutamina, dos ácidos graxos poli-insaturados e da parede celular de levedura (PCL) sobre a estrutura e ultraestrutura do intestino delgado e o desempenho de leitões. Foram utilizados 45 leitões, desmamados aos 21 dias de idade, para testar os seguintes tratamentos: T1 - dieta basal; T2 - dieta basal + 1% de glutamina; T3 - dieta basal + 0,2% de PCL; T4 - dieta basal + 5% de óleo de peixe. Nos dias sete e 14 pós-desmame, foram abatidos cinco leitões de cada tratamento. Os aditivos testados não alteraram a altura e a densidade dos vilos nem a profundidade das criptas do intestino delgado. Foi observado efeito de idade, mostrando redução na altura e na densidade dos vilos e na profundidade das criptas após o desmame. No duodeno e jejuno, foram observados maiores valores de relação vilo:cripta, que aumentaram com a idade pós-desmame. Ocorreram redução da altura dos microvilos do duodeno aos sete dias e aumento da largura dos microvilos do jejuno aos 14 dias pós-desmame. A área de superfície apical dos enterócitos não foi alterada pelos fatores estudados. Os aditivos estudados não foram eficientes em prevenir a atrofia da mucosa intestinal do jejuno, ao não interferir na sua ultraestrutura. Os aditivos incluídos na dieta não influenciaram o desempenho dos leitões no pós-desmame.

Uma arquitetura baseada em agentes para configuração dinâmica de aplicações inteligentes em ambiente foundation fieldbus

The industrial automation is directly linked to the development of information tecnology. Better hardware solutions, as well as improvements in software development methodologies make possible the rapid growth of the productive process control. In this thesis, we propose an architecture that will allow the joining of two technologies in hardware (industrial network) and software field (multiagent systems). The objective of this proposal is to join those technologies in a multiagent architecture to allow control strategies implementations in to field devices. With this, we intend develop an agents architecture to detect and solve problems which may occur in the industrial network environment. Our work ally machine learning with industrial context, become proposed multiagent architecture adaptable to unfamiliar or unexpected production environment. We used neural networks and presented an allocation strategies of these networks in industrial network field devices. With this we intend to improve decision support at plant level and allow operations human intervention independent

Agentes Inteligentes com Foco de Atenção Afetivo em Simulações Baseadas em Agentes

Simulations based on cognitively rich agents can become a very intensive computing task, especially when the simulated environment represents a complex system. This situation becomes worse when time constraints are present. This kind of simulations would benefit from a mechanism that improves the way agents perceive and react to changes in these types of environments. In other worlds, an approach to improve the efficiency (performance and accuracy) in the decision process of autonomous agents in a simulation would be useful. In complex environments, and full of variables, it is possible that not every information available to the agent is necessary for its decision-making process, depending indeed, on the task being performed. Then, the agent would need to filter the coming perceptions in the same as we do with our attentions focus. By using a focus of attention, only the information that really matters to the agent running context are perceived (cognitively processed), which can improve the decision making process. The architecture proposed herein presents a structure for cognitive agents divided into two parts: 1) the main part contains the reasoning / planning process, knowledge and affective state of the agent, and 2) a set of behaviors that are triggered by planning in order to achieve the agent s goals. Each of these behaviors has a runtime dynamically adjustable focus of attention, adjusted according to the variation of the agent s affective state. The focus of each behavior is divided into a qualitative focus, which is responsible for the quality of the perceived data, and a quantitative focus, which is responsible for the quantity of the perceived data. Thus, the behavior will be able to filter the information sent by the agent sensors, and build a list of perceived elements containing only the information necessary to the agent, according to the context of the behavior that is currently running. Based on the human attention focus, the agent is also dotted of a affective state. The agent s affective state is based on theories of human emotion, mood and personality. This model serves as a basis for the mechanism of continuous adjustment of the agent s attention focus, both the qualitative and the quantative focus. With this mechanism, the agent can adjust its focus of attention during the execution of the behavior, in order to become more efficient in the face of environmental changes. The proposed architecture can be used in a very flexibly way. The focus of attention can work in a fixed way (neither the qualitative focus nor the quantitaive focus one changes), as well as using different combinations for the qualitative and quantitative foci variation. The architecture was built on a platform for BDI agents, but its design allows it to be used in any other type of agents, since the implementation is made only in the perception level layer of the agent. In order to evaluate the contribution proposed in this work, an extensive series of experiments were conducted on an agent-based simulation over a fire-growing scenario. In the simulations, the agents using the architecture proposed in this work are compared with similar agents (with the same reasoning model), but able to process all the information sent by the environment. Intuitively, it is expected that the omniscient agent would be more efficient, since they can handle all the possible option before taking a decision. However, the experiments showed that attention-focus based agents can be as efficient as the omniscient ones, with the advantage of being able to solve the same problems in a significantly reduced time. Thus, the experiments indicate the efficiency of the proposed architecture

Agentes polinizadores e produção de grãos em cultura de café arábica cv. “Catuaí Vermelho”

Coffee (Coffea arabica L.) plants had the pollination process of their flowers studied in three coffee producing regions in Brazil: the first in Ribeirao Preto, state of São Paulo, in September of 2004, the second in Carmo do Paraiba, in the state of Minas Gerais, in October of 2006, and, the third, in Altinopolis, state of São Paulo, in September of 2007. In all these locations the coffee variety used was the 'Catuai Vermelho'. The pollinator species visiting the flowers, the frequency with which the flowers were visited by the insects, and the type of material collected by them ( nectar and/or pollen) were determined by counts taking place at the first 10 minutes of each hour from 7:00 AM till 6:00 PM during the months mentioned above. To estimate the fructification percentage, 25 branches were identified with color threads and protected with wire frames covered with a nylon fabric to prevent them from being visited by insects. Another group of 25 branches was similarly identified but remained without any covering so that their flowers were thus freely visited by insects. on the average, the most frequent pollinator was the Africanized bee Apis mellifera (73.7%) followed by the bee Trigona spinipes (14.5%), and Tetragonisca angustula (9.5%). The Africanized bee collected nectar and pollen to almost the same extent: 58.5% of the first and 41.5% of the second. To collect nectar, that species increased its visiting frequency up to 1:00 PM. To collect pollen, A. mellifera visited the flowers up to 1:00 PM with frequency peaks between 8:00 and 9:00 AM. T. spinipes collected pollen (58,5%) and nectar (41.5%). T. angustula collected only pollen. The branches freely visited by insects produced 181 grains on the average whereas those covered with the nylon fabric produced only 81 grains, this meaning a reduction of 55.25% in grain production. Coffee grains produced on the freely visited branches had a mean weight (1.13 g) significantly superior to that of those produced on the covered branches (0.94 g).

Verificou-se forte ação fungicida com o uso do herbicida glyphosate, assim como os outros avaliados in vitro, sobre os fungos testados, e os mesmos resultados foram observados nas plantas em condição de campo.

Utilização de microemulsões como agentes modificadores de superfícies para remoção de íons metálicos

The heavy metals are used in many industrial processes and when discharged to the environment can cause harmful effects to human, plants and animals. The adsorption technology has been used as an effective methodology to remove metallic ions. The search for new adsorbents motivated the development of this research, accomplished with the purpose of removing Cr (III) from aqueous solutions. Diatomite, chitosan, Filtrol 24TM and active carbon were used as adsorbents. To modify the adsorbent surface was used a bicontinuous microemulsion composed by water (25%), kerosene (25%), saponified coconut oil (10%) and as co-surfactant isoamyl or butyl alcohols (40%). With the objective of developing the best operational conditions the research started with the surfactant synthesis and after that the pseudo-ternary diagrams were plotted. It was decided to use the system composed with isoamyl alcohol as co-surfactant due its smallest solubility in water. The methodology to impregnate the microemulsion on the adsorbents was developed and to prepare each sample was used 10 g of adsorbent and 20 mL of microemulsion. The effect of drying time and temperature was evaluated and the best results were obtained with T = 65 ºC and t = 48 h. After evaluating the efficiency of the tested adsorbents it was decided to use chitosan and diatomite. The influence of the agitation speed, granule size, heavy metal synthetic solution concentration, pH, contact time between adsorbent and metal solution, presence or not of NaCl and others metallic ions in the solution (copper and nickel) were evaluated. The adsorption isotherms were obtained and Freundlich and Langmuir models were tested. The last one correlated better the data. With the purpose to evaluate if using a surfactant solution would supply similar results, the adsorbent surface was modified with this solution. It was verified that the adsorbent impregnated with a microemulsion was more effective than the one with a surfactant solution, showing that the organic phase (kerosene) was important in the heavy metal removal process. It was studied the desorption process and verified that the concentrated minerals acids removed the chromium from the adsorbent surface better than others tested solutions. The treatment showed to be effective, being obtained an increase of approximately 10% in the chitosan s adsorption capacity (132 mg of Cr3+ / g adsorbent), that was already quite efficient, and for diatomite, that was not capable to remove the metal without the microemulsion treatment, it was obtained a capacity of 10 mg of Cr3+ / g adsorbent, checking the applied treatment effectiveness

Bairro Planalto, Natal-RN: agentes, usos e conflitos

This research has the goal to analyze the urban setting of the Planalto neighborhood, in Natal /RN, seeking to unravel the processes, agents and contradictions associated with the production of the space. The choice of neighborhood is justified by the observation that changes in its urban setting have been growing in speedy way. We highlight the performance of the housing market, in partnership with the state, and the construction of condominiums and buildings closed by the housing program Minha Casa, Minha Vida. This has favored the reproduction of a new " urban reality in the neighborhood, setting an urban standard that differs from the original morphology, seen as peripheral within the urban dynamics of the city. The research is a qualitative study, through documents, interviews with stakeholders, and photographic documentation. In this perspective , we seek to understand the current phase (2000s) the production of space in the neighborhood process through the development of the housing market , as an extension of the urban development in central zone of Natal/RN, analyzing the performance of agents and their producers the "new " uses redefining the "old ". Thus, it can be seen that there is in the neighborhood, urban reality in a pluralistic constitution, from the existence of different social classes inhabiting the same space. On this way, the city is produced from the appropriation of space by different social classes, although due to the economic condition of each of them

Analisando conhecimentos e práticas de agentes educacionais e professoras relacionados à alimentação infantil

Objetivou-se identificar os conhecimentos e as práticas relacionados à alimentação de crianças entre zero e três anos, a fim de complementar a formação das profissionais que trabalham com crianças, na área da educação nutricional. O procedimento metodológico seguiu as orientações do estudo de caso, com abordagem qualitativa. Os saberes e as práticas das participantes do estudo foram analisados por meio de questões abertas e fechadas e das observações dos tópicos relacionados à nutrição infantil, juntamente com os dados sobre a formação dessas profissionais. Pode-se concluir que tanto as agentes educacionais quanto as professoras de Ensino Infantil são detentoras de um conhecimento sobre Nutrição Infantil, porém a preocupação maior destas foi atender as necessidades nutricionais das crianças por meio de uma boa alimentação, deixando, em segundo plano, as atividades pedagógicas, as quais poderiam ser realizadas em um programa de educação nutricional, construído coletivamente e inserido no projeto político-pedagógico da escola.

Realidade virtual na atividade cerebral: um estudo comparativo entre estados emocionais de adultos jovens e idosos

The association of Virtual Reality (VR) to clinical practice has become common in the recent years, showing to be an additional tool on health care, especially for elderly. Its use has been related to higher therapeutic adhesion levels and well being sensation. Such emotional based aspects are often observed by subjective tools of relative validity. This study analyzed the immediate effects of varied VR contexts balance training over emotional behavior, which was observed under peaks of maximum expression of EEG waves. Methodology: 40 individuals, divided in two groups, both gender, 20 young and 20 elderly, were submitted to a 60 minutes intervention, including balance training under VR. The first 25 minutes referred to initial evaluation, general orientation and cognitive assessment by the use of Mini Mental. The next ten minutes were designated to the avatar creation and tutorial video presentation. Through the following 20 minutes, the individuals from both groups were exposed to the exact same sequence of games under virtual contexts, while submitted to electroencephalography by Emotiv EPOC® focusing Adhesion, Frustration and Meditation states. The virtual interface was provided by the Nintendo® game, Wii Fit Plus, with the scenarios Balance Bubble (1), Penguin (2), Soccer (3), Tight Rope (4) and Table Tilt (5). Finally, a questionnaire of personal impressions was applied on the 5 minutes left. Results: data collected showed 64,7% of individuals from both groups presented higher concentration of adhesion peaks on Balance Bubble game. Both groups also presented similar behavior regarding meditation state, with marks close to 40%, each, on the same game, Table Tilt. There was divergence related to the frustration state, being the maximum concentration for the young group on the Soccer game (29,3%), whilst the elderly group referred highest marks to Tight Rope game (35,2%). Conclusion: Findings suggest virtual contexts can be favorable to adhesion and meditation emotional patterns induction, regardless age and for both sexes, whilst frustration seems to be more related to cognitive motor affordance, likely to be influenced by age. This information is relevant and contributes to the orientation for the best choice of games applied in clinical practice, as for other studies regarding this topic
