O controle da tuberculose no contexto da atenção primária à saúde no Brasil

O Brasil é um dos países que concentram 80% da carga de tuberculose no mundo. No contexto da atenção primária brasileira, fatores interferem para que as equipes de saúde da família possam incorporar as atividades de controle da doença no processo de trabalho. O controle da doença depende da forma como os serviços de saúde estão organizados para garantir o acesso ao diagnóstico precoce e ao tratamento. Esse estudo tem como objetivo geral analisar o controle da tuberculose no contexto da atenção primária à saúde no Brasil. Os objetivos específicos são comparar o tratamento diretamente observado com o regime autoadministrado em pessoas com tuberculose; Verificar se o Programa Nacional de Controle da Tuberculose é avaliável e elaborar um modelo teórico e lógico para avaliação deste programa; avaliar a relação entre porte populacional dos municípios e as características de estrutura e processo de cuidado a pacientes de tuberculose na atenção primária no Brasil. Realizou-se uma revisão sistemática, seguida de um estudo de avaliabilidade e de um estudo transversal. Os achados da revisão sistemática revelam que não houve diferença significativa entre os grupos de tratamento (observado e não observado) para cura (OR 1,06. IC95% 0,75 - 1,50) e para conclusão do tratamento (OR 1,64, IC 95% 0,79 - 3,42). Menor abandono no grupo com tratamento supervisionado e não houve diferença estatisticamente significativa entre os grupos (OR 0,73, CI 95% 0,58-0,92). O risco de morte foi maior no regime de tratamento autoadministrado (OR 1,49 IC 95% 1,03 - 2,45). A hetorogeinadade entre os estudos analisados não permite afirmar que nao há diferença estatisticamente significativa para cura e tratamento concluído. A pré-avaliação do Programa de Controle de Tuberculose possibilitou a descrição do Programa, elaboração e pactuação do modelo lógico e a matriz de relevância dos indicadores. Caracterizou-se os seus elementos estruturantes, definição de indicadores de estrutura e processo, além das perguntas avaliativas. Uma avaliação somativa com enfoque na análise dos efeitos da intervenção de controle da tuberculose é recomendada. A avaliação das características de estrutura e processo de cuidado à pessoa com tuberculose revelou melhor desempenho para as equipes de atenção básica de municípios classificados como metrópole no acesso, coordenação do cuidado e qualidade técnica da atenção. Em relação ao acesso: 98,5% acolhimento a demanda espontânea; 95,8% programação de consultas. Na coordenação do cuidado, 93,2% existência de protocolo para tuberculose. Quanto a qualidade técnica da atenção à tuberculose verifica-se que 93,4% acompanhamento de tratamento diretamente observado, 95,8% com busca ativa de faltosos ao tratamento, 64,0% oferta de ações educativas, 91,3% busca ativa de sintomáticos respiratórios. Cabe destacar que metrópoles apresentaram maior tempo médio de espera para escuta/acolhimento (24,41 minutos); para consulta previamente agendada (23,52 dias); para consulta em pneumologia (87,12 dias). Percebem-se fragilidades na estrutura e processo da atenção à tuberculose, principalmente no controle especializado da doença e na qualidade técnica entre os municípios. Recomenda-se reforço, particularmente na qualidade técnica para aumentar a cobertura de acompanhamento do tratamento, busca de sintomáticos respiratórios e das ações educativas.

Relação entre ciclo de vida do produto turístico e estratégias de cooperação na faixa litorânea urbana do município de Natal

Tourism in the Northeast of Brazil was introduced as an alternative economic development for the Region by federal promoting policies that focused primarily in structuring the local geographic area. With the completion of these structuring actions, mass tourism expanding the area, as well as spread actions based on cooperation and formalization of governance institutions. This study aimed to examine the relationship between the life cycle of the tourism product 'Coastal Cities of Natal and the cooperation strategies in a historical perspective. Thus was submitted to the life cycle of the tourism product 'Coastal Cities of Natal ; the major projects of tourism development were mapped, the existing cooperation strategies were characterized, and investigated the influence of the cooperation actions for the current stage of product. The specific theoretical support to tourism was built on the perspective of the Theory of Population Ecology, System of Tourism and Touristic Product Life Cycle. Regarding to cooperation the theoretical foundation addressed issues of strategy, New Forms and Collective Efficiency. The survey consisted of a causal descriptive study, using a case study. We used the qualitative and quantitative methodological approaches, and data collected by consulting of secondary data and semistructured interviews with twelve staff working in tourism in Natal. Results showed that the life cycle graph of product 'Coastal Cities of Natal is moving from one stage of growth to a stage of maturity, with a primary upward trend and with crises that are up over the graph. They have been mapped six of tourism development projects of relevance to the product: The Politics of Mega Projects, PRODETUR/NE, Municipalization National Program of Tourism, Regionalization Program, Urbanization Project Beach do Meio and Actions for the Promotion of Destiny. They have been identified sixty-four participating players in process of tourism development, which twenty were considered relevant to the respondents. The main strategies identified for cooperation were the consortium, collective strategy and clusters. Results indicated that co-operation strategies were adopted so that the benefits were obtained at the collective level, dedicated to the strengthening of Natal Destiny and its products. The main reasons were the need of cooperative marketing, international market entry and actions inducing the state. Finally, it was concluded that strategies for cooperation related to product life cycle 'Coastal Cities of Natal' as that work in the consolidation of projects for development of tourism, when the efficiency of collective action is achieved

Estudo clínico-laboratorial e histopatológico de cães naturalmente infectados por Leishmania chagasi com diferentes graus de manifestação física

Canine Visceral Leishmania (CVL) is an important zoonotic disease that has a world wide distribution and has a large impact on public health on the American Continent, especially in Brazil, where the nature of endemic diseases in humans affects a large part of the nation. The influence of the prevalence of CVL in the increased rate of human cases in endemic areas and in the unleashing of epidemic outbreaks shows the need for a more profound understanding, that would generate significant advances in the current measures used to control the reservoirs of sickness that are practiced by the Programa Nacional de Vigilância e Controle da Leishmaniose Visceral. The present work describes and compares the clinical-laboratorial and histopathological findings of twenty-three dogs that were naturally infected by Leishmania chagasi, from endemic areas in metropolitan Natal, Rio Grande do Norte, Brazil. These animals, that were selected and given physical and serological exams (IFI and ELISA rK-39), were classified according to the degree of clinical severity and had blood samples drawn (whole blood and serum) for a complete hemogram and a coagulogram to be done as well as biochemical tests for kidney and liver function. The confirmation of infection by L. chagasi was done after the euthanasia of the animals, through the direct demonstration of the parasite in the impression of the spleen and liver crowned with GIEMSA and through a cultivation by means of NNN/Schneider. According to the clinical evaluation, the animals were classified as asymptomatic (7), oligosymptomatic (7) and polysymptomatic (9). Among the animals that were chosen to be autopsied, there were 2 asymptomatic, 3 oligosymptomatic and 3 polysymptomatic, for the purpose of studying their histopathology, having collected fragments of the spleen, liver, kidneys and skin and were fixed in 10% tamponed formol. The comparison between the average parameters of the clinical-laboratory tested animals in the groups was done through the Student t test (a<0.05). The main clinical signals observed were lymphadenomegaly, alopecy, dermatitis, exfoliation, cutaneous ulcers, onicogriphosis and emaciation. The main clinical-laboratorial alterations established, mainly in the polysymptomatic group, were anemia, hyperproteinemia, hyperglobulinemia, alterations in the albumin/globulin ratio and increased ALT activity. Renal alterations were not verified (urea and creatinine levels were normal). Thrombocytopenia was observed in three clinical groups. However, the other indicators of coagulation function (TAP and TTPA) did not have abnormal variations. There were inflammatory infiltrations and leishmania amastigotes in the skin of polysymptomatic dogs, however, they were not found in the skin of asymptomatic animals. Hypertrophy and hyperplasia of the phagocyte mononuclear system, leishmania amastigote parasites were found in the macrophages, extramedullary hematopoiesis and degenerative alterations were detected in the spleen and liver of 8 of the animals submitted to histopathological exams. In accord with these results, it was demonstrated that the expected alterations in the hematological and biochemical parameters in function of their viscerotropic nature of CVL are mainly observed in the more advanced stages of the disease. The absence of inflammatory infiltration and parasite load in the skin suggest that infected animals without symptoms may have an importance irrelevant to the infectiousness of the vector

Desenvolvimento de metodologias analíticas alternativas por cromatografia gasosa para análise de biodiesel

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Estado nutricional antropométrico, composição corporal e pressão arterial em adolescentes

Os objetivos deste trabalho foram: (1) estimar as prevalências de excesso de peso e de gordura corporal, obesidade central e pressão arterial elevada (PAE) em adolescentes beneficiários do Programa Nacional de Alimentação Escolar (PNAE) da rede municipal de ensino de Natal-RN; (2) verificar a associação entre variáveis antropométricas e de composição corporal com a pressão arterial, a maturação sexual e a história familiar positiva de fatores de risco para doença cardiovascular (FRDCV); (3) comparar dois padrões de referência para classificação do excesso de peso em adolescentes; e (4) propor equações preditivas de massa gorda (MG) e massa livre de gordura (MLG) baseadas nos perímetros corporais. Trata-se de um estudo transversal, com 526 adolescentes beneficiários do PNAE, em Natal, Brasil. O tamanho da população de estudo foi definido por amostragem aleatória, em dois estágios, e ponderada segundo número de alunos de cada escola. No primeiro estudo, o excesso de peso foi determinado por Índice de Massa Corporal (IMC), a gordura corporal estimada por dobras cutâneas e a obesidade central por perímetro abdominal. A pressão arterial elevada foi classificada conforme a American Academy of Pediatrics. As prevalências foram apresentadas em valores relativos e efeito do desenho. Realizou-se uma análise fatorial para sintetizar o conjunto de variáveis antropométricas visando identificar fatores comuns. Extraíram-se dois fatores: (1) padrão excesso de adiposidade e (2) padrão adiposidade central elevada. Para avaliar a associação entre os padrões de adiposidade corporal com pressão arterial elevada, faixa etária, maturação sexual e história familiar de FRDCV utilizou-se a Razão de Chances e respectivo intervalo de confiança de 95% e regressão logística. No segundo estudo, calculou-se a sensibilidade e a especificidade do excesso de peso classificado segundo o IOTF e a World Health Organization WHO em relação ao excesso de adiposidade corporal; e a estatística Kappa para medir a concordância entre os dois padrões de referência. No terceiro estudo, foram elaborados modelos preditivos de MG e MLG com base em nove perímetros corporais, utilizando a bioimpedância Byodinamics 450 como padrão de referência. Para tanto foram selecionados 218 adolescentes eutróficos, segundo o IMC a partir do estudo transversal. As equações foram estimadas por regressão linear múltipla, considerando a idade e os perímetros corporais. Os resultados apontaram que 14,1% dos meninos e 15,7% das meninas tinham excesso de peso; 15,3% dos meninos e 11,6% das meninas tinham excesso de gordura corporal e dentre os meninos 14,3% tinham pressão arterial elevada e as meninas, 21,4%. Todos os efeitos do desenho foram inferiores a 2,5%. Nos meninos, o padrão excesso de adiposidade foi associado à história familiar positiva de FRDCV (ORajust=2,60; 1,09-6,22), maturação sexual (ORajust=2,92; 1,04-8,22) e PAE (ORajust=3,66; 1,34-9,94). Os meninos com 12 anos e mais apresentaram 6,1 vezes mais chance de apresentar padrão adiposidade central elevada do que os adolescentes com 10 a 11 anos (IC95% 2,32-16,04), assim como os púberes apresentaram 3,2 vezes este mesmo padrão em relação aos pré-púberes (IC95%1,14-8,85). A partir da comparação entre os dois padrões de referencia de classificação do excesso de peso por meio do IMC, observou-se que a sensibilidade foi de 79,3% para o critério IOTF e de 88,9% para WHO e a especificidade foi de 94,7% e 89,9%, respectivamente. O nível de concordância foi maior para o critério IOTF (Kappa=0,70 x Kappa=0,64). Em relação à construção das equações preditivas de gordura corporal, do total de 106 meninos e 112 meninas, foram desenvolvidas duas equações para estimar MG e duas para MLG, considerando o sexo. No sexo masculino, a equação para estimar a MG incluiu as variáveis idade, punho, quadril e perímetro abdominal (R2=0,552; AIC=416,04) e MLG, idade, punho e antebraço (R2=0,869; AIC=578,24). Enquanto que no feminino, MG foi estimada pelas variáveis punho, perímetro do abdômen, do quadril, da coxa proximal e da panturrilha (R2=0,838; AIC=415,36); e a MLG por idade, punho, perímetro do abdômen, do quadril e da panturrilha (R2=0,878; AIC=512,48). Conclui-se que os adolescentes tinham elevada prevalência de excesso de adiposidade corporal e de pressão arterial elevada. Tanto o padrão excesso de adiposidade quanto adiposidade central elevada constituem-se em padrões de risco. O padrão excesso de adiposidade foi associado à pressão arterial, história familiar positiva de FRDCV e maturação sexual em meninos. O critério IOTF mostrou-se menos sensível, mais específico, com maior nível de concordância e maior probabilidade de identificar corretamente o excesso de gordura corporal nos adolescentes avaliados. Quatro equações foram desenvolvidas para a estimativa da MG e MLG em adolescentes. As equações desenvolvidas para estimar a MG no sexo feminino e MLG para ambos os sexos apresentaram valores elevados de coeficiente de determinação ajustados e, portanto, são as preferenciais. Este estudo foi realizado com a participação de equipe multidisciplinar composta por professores da área de Nutrição, Endocrinologia Pediátrica, Estatística, Educação Física, discentes do Curso de Graduação em Nutrição e residentes em Pediatria

Estratégias de intervenção utilizadas por enfermeiros da ESF do município de Natal/RN no controle do câncer do colo de útero

Cancer of the cervix (cervical cancer) is the second most prevalent cancer among Brazilian women. The high rates of cervical cancer in Brazil justify the implementation of effective strategies to control this, which include actions to promote health, primary prevention, early detection, screening, treatment and palliative care. Despite the existence of the National Programme for Control of the CCU there was no reduction in the incidence and mortality of this disease in Brazil. The Family Health Strategy (FHS) has the potential to facilitate such control and, in this context, one should consider that nurses play a central role. The study aimed to know the general intervention strategies used by nurses FHS of Natal / RN in CCU control, and how specific: analyzing the knowledge of these nurses on the CCU, the actions developed in the ESF for the control of CCU and identify the difficulties faced by them to perform it. This is a descriptive exploratory quantitative developed through a structured interview guide with 106 nurses who have experience in controlling the CCU in FHS teams of Natal / RN. Data analysis was performed using descriptive statistic s. The results pointed to actions taken in the FHS to control the CCU, collection of cervical cancer screening, health education activities, nursing consultation, referral of suspected cases for medical monitoring and active women with abnormal test result . The actions that were not mentioned by the nurses included: forming groups of prevention and health promotion; expand coverage of exams and office hours of consultations, establishment of alternatives to end the pent-up demand in the health units, participation in treatment or rehabilitation process users with the CCU; interventions for pain management, alliances and partnerships with schools, in dustry and the use of protocols. This study can be seen that the practice nurses partially shares to the CCU in Natal / RN. The participants of this study, when asked about the CCU, specifically for signs and symptoms of disease and risk factors in general showed important gaps. Difficulties such as lack of materials for collection of Pap smear; inadequate physical space in the Health Units; pent-up demand in the service, delay in arrival of the test results; obstacles in the actions of referral and counter-referral and cultural factors make the CCU control is compromised. It is believed in this research contributed to a reflection on the importance of the role of nurses in the development of the ESF control actions CCU, pointing out the factors that affect these. It is important to involve all nurses who comprise the ESF as knowledgeable of the risk factors, signs and symptoms, and existing tools for the early detection of cervical cancer in the pursuit of quality improvement actions to promote women`s health, contributing in planning future interventions that may reduce mortality from this disease in Natal / RN.

Fonte de energia alternativa: um estudo sobre a percepção ambiental, social e econômica do biodiesel com docentes do Centro de Tecnologia do gás da cidade de Natal RN

Meaning fuel and renewal energy source s derivative additives, the term biodiesel exists in Brazil since 1980, when it was signed its first patent by Expedito Parente. Since then, its importance has grown gradually due to the worsening of the ambient problems, since its use has became a highly promising alternative to the pollution decrease, as in the carbon dioxide issue as with the smoke and sulfur oxide. In Brazil, it was created the National Program of Production, whose objective is to insert the new product in the country s energy matrix, strengthening the economy and creating new employment opportunities, being an important product to the national energetic independence, since Brazil still imports diesel to its domestic consumption. This study aims to identify the ambient, social and economic perception of the teachers from the Technology Center of Natal city (CTGÁS-RN) to the biodiesel. For that, it was used a questionnaire closed questions, organized in the likart scale, directed to the tree spheres of the research analysis, the biodiesel and its social, ambient and economic nuances, totaling 31 questionnaires full answered. In its objectives, the research was descriptive and in its approach it was qualitative. To the data analysis it was used statistical tools (Statistic software, 6.1 version and Microsoft Excel 2003). The research revealed the predominance of the ambient aspect in the sight of the teachers, followed by the social ones. The economic factors represent a minor percentage in the analysis when compared to other

A produção de biodiesel no assentamento Canudos RN: perspectivas e limites da inclusão social

The need to become energy self-sufficient a country with which Brazil has sought renewable energy sources due to the possibility of depletion of oil in coming decades. This paper will examine the perspective of social inclusion the latest energy plan developed by the Federal Government: the National Program of Biodiesel Production and Use - PNPB. It aims to find out whether that work with family farmers who participated in the PNPB socially included and what limits its inclusion. Secondly, the objective is to analyze the Brazilian biodiesel production and its uses. The methodology used for the preparation of this study was to examine the literature, visits to the study area, conducting interviews with the leadership of the settlement, questionnaires and semi-structured interviews with families producing sunflower. Finally, the research dealt with the statistical data. After analyzing the data was verified that the instrument PNPB is able to promote the social inclusion of family farmers, but this occurred in the initial stages because the families involved need a minimum framework of organization and infrastructure to develop activities related to biodiesel

Entre missas e batuques: Irmandade de Nossa Senhora do Rosário dos Homens Pretos em Recife, Goiana e Olinda - Século XVIII

This work is a comparative study of three black brotherhoods that existed in Pernambuco in the eighteenth century, it is the Brotherhood of Our Lady of the Rosary of Black Men of Recife, Olinda and Goiás. The goal was to understand the similarities and differences between them, taking as benchmark their operating statutes, called Appointments. From the data analysis of the commitments associated with other documents produced by the Brotherhoods and the administrative and religious authorities, we sought the social profile of the villages in evidence, as well as the participation of black people inside. We sought to understand the historical conditions of that period, from the fact that the slave society, the black was placed in a position of subordination. However, as a carrier element of culture, although this condition, was able to overcome social obstacles, opening possibilities for own cultural manifestations of his group could occur. The coexistence in the Brotherhoods of the Rosary, which in addition to organizations for mutual assistance within the Catholic religion, is also constituted as fields mediators between high culture and popular culture, made those organizations become social spaces and representation allowed the existing order. The Brotherhoods of the Rosary in Recife, Olinda and Goiás, had their own hierarchical logic that engendered the construction of new black identities marked by cultural circularity that became possible due to the Atlantic diaspora process

Consumo c(l)iente: abordagem do gênero anúncio publicitário em livros didáticos de língua portuguesa do ensino médio

Portuguese language textbooks, according to what has been preconized on the official document to education, have been configured on discursive genres imported from diverse spheres of human activity. Adverts, genre of ample social circulation, spread from the Advertising sphere to the schools and started being approached by these collectaneas as an object and a tool for teaching. Therefore, this research deals with the approach of ads in Portugese textbooks. These discursive practices matter for the impact or appeal they exert over the (new) consumers, among which High School students; for their representation in the capitalist system, which guides us on our relationships and social practices; and for the mix of languages that end up at their composition, once they encapsulate the spirit of our time, par excellence, the one from the verbal-visual genres. To understand the treatment given to these advertising pieces, from questions/commentaries related to them, two collections were selected by the Programa Nacional do Livro Didático – Textbook National Program (PNLD 2012) among the ones more used by public High Schools in Natal/RN. From Applied Linguistics, from mestizo, nomadic and inter/transdisciplinary identity (MOITA LOPES, 2009), this study falls within the discursive chain of the interpretive tradition of historical-cultural approach (FREITAS, 2010) and names the Bakhtin Circle and its language‟s dialogical conception as inescapable partners. The data of the colletaneas show that the genre approach can happen as concrete utterance, as linguistic artifact and as hybrid, at work with questions and without questions, with the predominance of its occurrence in the portion of the volume devoted to the study of grammar. In the literature chapters and production/interpretation of compositions, it insert is incipient or it doesn‟t happen in the volume. Such a provision has implications for multiliteracies (ROJO, 2012) of the citizen student, once the lack or the abundance of critical reading proposals for this genre, that demand from the student the exercise of knowledge that is necessary to the construction of linguistic and social meanings, can be responsible for guide to a more conscious consumerism (material and cultural) by the chief customers of the work under review. The approaches of the genres seems to indicate a gradual transition that such material have undergone, which means, from the focus on clauses to the focus on utterances, or even the approach as linguistic artifact to hybrid and the concrete utterance, in search of overcoming the traditional tendency of taking advantage of formal aspects of the language, to the detriment of enunciative ones, and for coming into harmony with the guidelines and parameters of teaching in contemporary times, bringing the school duties close to the rights in life.

Possibilidades de enfoque CTS para o ensino superior de química: proposta de uma abordagem para ácidos e bases

Scientific education has been passing by redefinitions, contestations and new contributions from the research on science teaching. One contribution is the idea of science and technology literacy, allowing the citizens not only knowing science but also understand aspects on the construction and motivation of scientific and technological research. In accordance with this idea, there is the Science-Technology-Society (STS) studies which, since the 1970s, has been contributing for science teaching and learning according to the comprehension of the relationships with society in the Western countries of the North. In Brazil, this approach began to gain projection from the 1990s when the first essays on the theme were published. Currently, there is a clear influence of this approach on the national curriculum guidelines, especially for the area of Natural Sciences, and also on the textbooks chosen by the High School National Program (Programa Nacional do Ensino Médio). However, there seems to be a gap in relation to the discussion on the specific curricular component seen in college on this approach. Thus, this study aims at adopting the approach STS, face to the preparation of complimentary educational material on acid and bases concepts studied in the course of General Chemistry of the Natural Sciences graduation program. To this end, it was performed a bibliographical research aiming at making the state-of-the-art in in these concepts in specific literature to science teaching. It is divided in two stages: systematic study (with sixteen journals chosen according to Qualis-Capes and an unsystematic study with direct search in databases and references in the papers of the systematic study. The studies had their content analyzed and the categories chosen a priori were the level of education, the acid-base theory adopted, and the strategy/theoretical frame of reference adopted. A second stage aimed at identifying attitudes and beliefs on STS (Science-Technology-Society) and CSE (Chemistry-Society-Environment) of students in the teacher and technologist training course in three diferent institutions: UTFPR, UFRN and IFRN. In this study, it was used two questionnaires, composed of a Likert scale, semantic differential scale and open questions. The quantitative data reliability was estimated through Cronbach’s alpha method, and tha data were treated according to classic statistics, using the mean as the centrality measures, and the mean deviation as dispersion. The qualitative data were treated according to the content analysis with categories taken from the reading of answers. In the third stage, it was analyzed the presence of STS and CSE content in chapters on acid and bases concepts of nine General Chemistry textbooks, frequently used in graduation programs in public institutions of the state of Rio Grande do Norte. The results showed that there are few proposals of acid and bases teaching, and they are generally aimed at High School or at instrumentation for teaching courses, and no course for General Chemistry. The student’s attitudes and beliefs show the presence of a positivist point of view based on the concept of Science and Technology neutrality and the salvation of its mediation. The books analysis showed just a few content on STS and CSE are found in the studied chapters, and they are generally presented disjointedly in relation to the rest of the main text. In the end, as suggestion to solve the absence of proposals STS in General Chemistry books, as well as the student’s positivist attitudes, it was developed some educational material to be used in the course of General Chemistry at College. The material is structured to introduce a historical view of the concepts preparation, present the use of materials, the industrial and technological processes, and social and environmental consequences of this activities

A configuração do circuito espacial de produção sucroalcooleira em Alagoas

The sugarcane production consists in the principal product activity in the state of Alagoas, holding a structure composed of 25 unities of production that represents the economic base of more than a half of its municipies, what make it be the biggest producer of the sector in North and Northwest, exporting its products for countries in different continents. From this reference, it was searched in the present work, to understand the configuration of the circuit space production of sugar cane in Alagoas, from the use of the territory, trough the analyses of the more significant events related to the sector, and, the established rules by the State, through the government, by organs like Institute of Sugar and Alcohol (IAA), and programs like National Alcohol Program (Proálcool), between others, that had as function to structure and to allocate resources to the sugar cane sector. It was realized that the investments done made possible the renovation of techniques used in the sugar cane complex. In the beginning, with the substitution of the mill for factories and, afterwards, the improvement of the agriculture and factory process themselves, improving the utilization of the byproduct, and the productive integration of instances, specially with the sugar, cane, electricity generation production, intensifying the participation of the state in the internation division of labor, giving it a organization structure divided by big hegemonic agents of this process. SO, the sugar cane geographic configuration existing in alagoano territory was restructured and the circuit even more pass to constitute movement of many scales, subsidized by cooperation circles. However, this configuration showed itself subservient to world commerce, what conditions the adoption of hegemonic practices that are far from the local projects and living practices. The verticality imposed offers a configuration that isn’t peculiar, that only serves to answer to the big hegemonic agent commands, characterizing the continuity of the present capitalism process. It means that the sugar cane factories use corporately the territory as resource to obtain more lucrativity and this way dominate the bigger quantity of consumer commerce

Produção do espaço e reestruturação produtiva do setor de laticínio no Rio Grande do Norte

Since the 1970s, Brazil has gone through several changes in its economic and productive structures, which have symbiotic relationship with the organization and dynamics of the Brazilian territory. This set of economic, social and technical-scientific transformations developed in the amid the productive capital restructuring, a process that occurs on a global scale, but that effective with particularities in different places. Adopting this presuposition the present research had as main objective analyze the productive restructuring of the dairy sector in Rio Grande do Norte, highlighting its relationship with production process / organization of space and its impact on the social relations of production. The adopted methodology to elaborate of this study was based on the achievement a bibliographic review with regard to proceedings of production of space and productive restructuring, document research about the dynamics of the dairy sector in Rio Grande do Norte, as well as on regulatory instructions governing the dairy production in Brazil, we achieve parallel secondary data collection, with official organs such as IBGE, EMATER and SINDLEITE. Another important methodological resource was the realization of the field research, which enabled us to empirically understand the distinct realities lived by agents acting on milk production system in Rio Grande do Norte. The analyzes performed nevertheless evidence that the restructuring process in the dairy sector is fomented, greatly by state,that finance, encourages and normatizes the production of milk in the country. In the specific case of Rio Grande do Norte, this process is boosted by the creation of "Programa do Leite," which by constituting of an institutional market, contributes to the strengthening and expansion of industries, the detriment of the artisanal processing sector. Nevertheless family farmers continue to act in the activity, be only producing and trading fresh milk, supplying milk to processing units, mediating the production of their peers or by the craft benefiting milk in traditional cheese factories presents in the entire state of Rio Grande do Norte. The results reveal that it is a complex web of social relations of production that are established at the heart of laticinista activity in the Rio Grande Norte, these are summarily marked by relations of competition and complementarity between industrial and artisanal processing of milk

Avaliação de política pública: o ProInfo e sua gestão no município de Parnamirim (2009-2012)

The dissertation assesses aspects of the management of IT in Education Program (ProInfo), in the municipality of Parnamirim-RN. Checks as their management functions, with the following objectives: a) Examine whether the objectives of the activities related to teachers' program are being implemented according to the official documents, b) examine if there is a monitoring program activities as the activities of teachers c) Identify whether teachers develop activities and environments using the technological resources of the internet. The research brings a central issue: How ProInfo is subsidizing the activities of the teachers involved in the program to achieve their goals effectively? As a central hypothesis of this work, to be a general north to the research, we have: the ProInfo establishes a fragile and discontinuous link between the management of the activities of teachers and the goals that he sets. The hypothesis was validated by the analysis of data from field research, when we encounter a series of limiting aspects of program effectiveness at the municipal level. This research was undertaken with managers of state and municipal schools and teachers, using a sample of four schools Parnamirim-RN, in order to include some aspects of program management at the municipal level and effectiveness goals proposed, focusing on teachers who participated in the training. The methodological process consisted of literature review, interviews and documentary analysis carried to the organs responsible for ProInfo statewide (UNDIME/RN ) and municipal level, next to the Municipal Education Parnamirim-RN. Based on data collected from empirical field research, it was found that the ProInfo lacks periodic reviews by the governing bodies of the program, about the actions developed through appropriate instruments, which enable a more realistic view of the results of the program ex post (during or after deployment)
