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

Ce travail est une reflexion sur les pratiques éducatives dévelloppées par des élèves/professeurs dans le Cours de Formation d Éducateurs de la Campagne, réalisé dans un partenariat entre l Université Fédérale du Pará (UFPA), Le Movimento dos Trabalhadores sem Terra (MST Mouvement des travailleurs sans Terre) et le Programme National d Éducation dans la Réforme Agraire (PRONERA), en ayant comme son objectif stratégique rechercher les éléments facilitateurs de l articulation théorie-pratique dans les procédures méthodologique du Cours, fondé sur Paulo Freire. Nous approfondissons des réflexions sur la production d une proposition d Éducation de la Campagne qui, entre autres éléments, se fonde sur la Pédagogie de l Alternance, spécifiquement en ce qui concerne lês catégories Temps École et Temps Communauté. Dans le procès de recherche, nous utilisons comme ressources les documents écrits (dês projets de cours, des rapports, des journaux de la campagne document qui registre le quotidien des activités et des choses réalisées), et les discours des élèves de l Assentamento Palmares II , pendant et après lê Cours. À l analyse, nous identifions comme éléments facilitateurs de la relations théorie et pratique, le Temps École et le Temps Communauté en créant des opportunités, la rélation de ce qui se caracterise comme praxis (action-refléxion-action), en utilisant la recherche comme moyen d insertion dans la réalité et l´existence de groupe (colectif), ce qui a possibilité la participation colective aux réalisations des pratiques pédagogiques plus significatives dans le procès de Formation d Éducateurs de la Campagne, en ayant comme objectif la contribution dans la formation des sujets réalisateurs de leur histoire

O livro didático de história: um caleidoscópio de escolhas e usos no cotidiano escolar (Ceará, 2007 2009)

In the first decade of the XXI century, it is possible to assert that school textbook is part of the material culture of most public Brazilian schools by means of National School Textbook Program (PNLD). This research aimed at identifying and analyzing textbooks choice in Ceara, relating it to the uses of such tool within school daily life. The setting for the study was four public schools, two of them placed in Fortaleza, and the other in Quixada. It evaluated the uses of textbooks in the 6th grade. As part of methodology, public managers were interviewed, teachers answered surveys, and a direct observation during History classes in 2008 school year was carried out. The observation was over after round chats with students in the class, in which each one designed draws and sentences concerning to the textbook. Furthermore, the study was based on MEC official documents that regulate the textbook choice process with National textbook Program announcement (PNDL/2008) and PNDL/2008 Textbook Guide, in addition to History textbooks schools used. Roger Chartier‟s concept of appropriation was an analysis category, as well as Michael de Certeau s strategy and tatics‟, and Dominique Julia‟s concept of school culture . The study recognizes textbook in the perspective of Alain Choppin and Egil Borre Johnsen, since it is a complex cultural object. For this reason, the study designs an analogy with a kaleidoscope that sends different images depending on who uses it, within a set of colorful lines, since textbook comprehends nowadays different sources and languages, as it offers countless possibilities of use in teaching History. The study concludes that only the main text of each chapter is really worked in daily class practice. Therefore, although theoretical and graphic changes in textbook production, the textbook is underused, which is central to a later rethought of teachers instruction, since, depending on the conception of teaching and learning, textbook potentialities will be used to improve the development of knowledge in History.

O PROEJA ensino médio no ifrn, campus Caicó: causas da desistência e motivos da permanência

This dissertation deals about the theme of National Integration Program of the Professional Education to the Basic Education in the form of Youth and Adults Education - PROEJA, which was developed at the Federal Institute of Education Science and Technology of Rio Grande do Norte - IFRN - Campus Caicó. It aims to analyze the causes of the abandonment and the reasons for the permanence of students within the mentioned program. To substantiate this research, we used methodologically, some procedures such as bibliographical research, documentary analysis, semi-structured interviews and focus group. To analyze the data, we discussed the contradiction that involves duality and educational compensation based in the struggles and achievements of rights at the core of public policies for high schools, for vocational education and the education of youth and adults in the 2000s. We analyze the integrated high school under PROEJA, having as reference the conception of the total human formation; the inseparability of the primary education system and vocational education and the integration of knowledge and expertise as a whole, discussing the specificities of the modality EJA, discussing the causes of abandonment and the reasons for the permanence of the students of education for youth and adults (EJA) in the primary education system. As for the results, we found that although the PROEJA be a program that aims to provide a complete human formation to contribute to the full citizenship of their graduate members, what is announced in the document that guides its creation has not been materialized in Caicó Campus. The curriculum of the course was not designed for the students of EJA, nor teachers have had an adequate training to work with these specific individuals, and its specificities of being workers with differentiated learning times have not been considered. In addition, the courses are predominantly of instrumentalist characteristics. This indicates that the material and institutional conditions to achieve the promised total and complete training have not being fully materialized at the researched school. Associated with the difficulties concerning the intra-school and extra-school conditions, personal and socioeconomic conditions which are related to the obligation to work that implies in limitations to balance work, school and family, they influenced in the interruption of the school trajectory of these subjects. Through research, we confirmed that the motives of students who remain have to do also with intraescolares conditions the quality of education (qualification of technical staff and teachers) involved in the educational process, as well as socioeconomic and personal issues represented by the support of colleagues and family.Then it is concluded that the causes of abandonment and the reasons of the permanence are of institutional, socioeconomic and personal origins. Finally, it is observed that capitalist society demands as much as possible high levels of educated workers, and at the same time makes difficult the access to that education for much of the population, and it is not randomly. The objects of that exclusion are the popular worker classes and their children

Gêneros do discurso e escrita: o que as coleções didáticas de português (des)prestigiam no ensino da produção textual?

Through the examination of official indicators, it can be observed that writing is pointed out as one of the main problems concerning formal basic education. However, this teaching-learning object is one of the central objectives at school, having an essential role in different curricular components as well as in the interaction demands required by society. Such paradox indicates, therefore, the relevance of investigations which analyze the intrinsic elements of child development as written text producer. Hence, the main purpose of this research consists of analyzing the treatment given to the types of discourse and the teaching situations in which the written text are produced, concerning Portuguese language didactic material collections approved by Programa Nacional do Livro Didático (PNLD 2010) the Brazilian program of didactic book and worked at elementary school. Such materials correspond to the collections adopted in municipal education system schools from Natal, RN which were below the official education indicator IDEB 2009. Thus, the questions that guide this work are: 1. During writing production lessons, is the diversity of types of discourse effectively worked on didactic collections? 2. Which are the types of discourse and the social spheres prioritized when teaching writing production? 3. How is the situation addressed in the production of the written text should be produced? For this research, we retook the authors Bakhtin, Bunzen, Faraco, Freire, Rodrigues, Rojo, Schneuwly e Dolz and we made a list of all types of discourse and spheres contemplated in the propositions of the writing production in didactical books, concerning the eight collections which compounds the first moment of analysis. Then, we verified how the situation of production is oriented by examining two didactic collections if and how they express the elements referring to the social-historical, functional and linguistic-discursive context of the text to be produced. The data obtained indicate: lack of diversification of types of discourse in the collection that compounds the Aggregate Sample of the research; the conception of a diversity based on the didactic of visiting; the recognition of all canonical and hegemonic types of text as one of the privileged objects of study; the centralization on the standard variety of the language and the devaluation of the representative types of cultural diversity; the shortage of productions which retrace to written language related to different technologies of communication and information; and the little emphasis on the types of discourse related to public language practices. As for the situations of production, it is observed the predominance of the school as a producer of dialogic relationships, whose propositions present, for example, text addressees, enunciative positions, support and contexts of restricted circulation, especially at school. Two divergent situations are observed among the collections: the lack of a work in which the situation of production is under the perspective of the types of discourse as object of teaching-learning; the concept of the types of discourse as object of reflection, presenting a differentiated didactic orientation towards the situation of production. This research contributes, therefore, with a mapping of the existence and the treatment of the types of discourse on propositions of writing production in didactic books; with the critical analysis of the approach of written activities, considering the elements of the historical-social, functional and linguistic-discursive context; thus, through teaching, research and public policies, use and selection of didactic material for the area

A participação das mães no conselho escolar do CMEI Amor de Mãe

This research aims to study the participation of mothers in the School Council of the Centro Municipal de Educação Infantil Amor de Mãe. The goal is to understand the relationship among concepts that mothers have and their practices as advisors. The historical-philosophical approach taken along the research permitted working with real people and not those derived or idealized ones. It searched an approximation of the mode of being and living of the councilor mothers in their homes, and the concepts and practices in the School Council. It was inspired by ethnographic researches to describe data, habits, cultural practices, meanings and values of people involved. As sources of research, we used: interviews with mothers and school staff; documentary and photographic collection of CMEI Amor de Mãe; local and national legislation; notebooks of the National Program for the Strengthening of School Council (2004); data bank of dissertations and theses of the Post-Graduate Program in Education of the UFRN dealing with democratic management and the relationship school and family. The study indicates the existence of a narrative of the school community that shows mothers as "missing" or "passive" and a practice that point out to how people participate actively in the school routine. This contradiction reveals the existence of a historically constructed school mindset that is rooted in a model of family and school that differs from the reality found in CMEI Amor de Mãe and how families served by CMEI Amor de Mãe organize themselves. It is recommended that the school community and families reorganize the conceptions that guide their practices in educating and caring for children with whom they live and work to make progress together in managing this process

Políticas públicas de educação ambiental: a gestão do programa municipal de educação ambiental de Mossoró/RN

Study about environment education public policies, emphasizing the directress since the 1970 . It analyses the environment education administration of Mossoró city, indentifying its articulation with the international directresses and the Environment Education National Policy (PNEA), established according the law number 9.795/99. The text takes as empiric reference the Environment Education National Policy (PNEA) of Mossoró city, realized since 2006. In order to make the research, we employed as methodologic proceedings a bibliographical and documental revision from wich we developed a contextualization of the propolsals toward a environment Education policy and administration, the institution of the environment Education in Brazil, in the neoliberal context on the State reform ambit. We also employed a semi-structured interview, having as individuals two Environment Education Municipal Program Administration of Mossoró city / RN state administrators and nine Municipal Education System educators. The analysis was done from the historic and dialetic perspective, trying to understand the facts in its totallity. The results revealed that the environment Education has become to be emphasize as an environment crises superation strategy since the 1970 s. In this context, the environment Education administration directress, in the United Nations (UN) initiative ambit, emphasizes the participation and the partnership as a way to share responsabilities between the State and society. In the neoliberalism affirmation context, in the 1990 s, these directresses were fortified, once, since the State reform, their functions were redimensioned and the State turns into a stronger planner an controller, inducing the society to act as a public polcies executor. Therewith, a deconcentration action process is consolidated, rather than an administrative and pedagocgic decentralization, historically revendicated on Education by the progressist sectors. Even though the administrators interviewed have revealed the wish that the schools become autonomous on the PMEA execution, through the NEAs, we notice that the methods employed do not contribute to that, because of the decisions concentration on the associated managership ambit and the few human and financial resources. In spite of the difficulties, the research showed that the Mossoró municipality innovated on the environment Education field, by the institution of the NEAs, even though they demonstrate fragilities regarding their performance, revealed on the educators and adiminstration talk on the interviews. We verify that the main difficulties come from the politc culture installed on the municipality, ruled by a technocracy and power concentration wich brings difficulties to the implementation of a democratic and participative administration, even though it would not be totally impossible, even on the circumstances described

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.

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

Política pública e educação digital no ensino fundamental em Natal/RN: análise de eficácia da atuação dos objetivos do Proinfo Municipal

The present work turns on the public politics of digital inclusion and of the impact of the Technologies of the Information and Communication in the formation of the citizenship. For this, it was opted for doing an analysis of effectiveness of the performance of the objectives of the Proinfo (National Program of Computer Science in the Education) municipal district of Natal-RN. As instrument of collection of data, three types of questionnaires were used. The collected data were analyzed and discussed starting from it analyzes it descriptive of averages and analyze of multiple regression. The results of the research pointed that the teachers and the students use the computer science in a restricted way. On the other hand, the digital education is not still totally contemplated in the schools beneficiaries' digital rérumé by Proinfo municipal and thus, the inefficacy of the program was verified with relationship the educational training and the students' digital inclusion

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

Avaliação da atenção à saúde de portadores de HIV no centro de referência para o tratamento da Aids em Natal/RN por profissionais e usuários do serviço

Objective: The aim of this study was to evaluate the health care of HIV/AIDS Reference Center for treatment of AIDS in Natal/RN for professionals and service users. Methods: This is an evaluative study with a quantitative approach, performed in the outpatient Giselda Trigueiro Hospital, in Natal (RN). The target population consisted of 313 patients with HIV and 34 professionals of the center. Data collection occurred from august 2007 to july 2008, with a structured form of interview, validated through a pilot study. The data were analyzed by descriptive and inferential statistics. Results: The evaluation of the service was considered unsatisfactory by 85.6% users. However, 58.8% of professionals considered it satisfactory. There was difference in the evaluation of the following indicators: the relationship professional users, offering support, timeliness of professional guidelines on the treatment. There was similarity in the following indicators: physical structure, respect for privacy, opportunity to make complaints, hospitality, convenience of schedules, availability of ARVs and laboratory tests, and ease of access. Conclusion: The results point to dissatisfaction of the users and professional satisfaction with the health care of people with HIV / AIDS in the service searched. It was found that the indicators used in this study may be considered relevant to evaluate the service in question, as well as monitoringparameters provide acceptable quality of health care by the National STD/AIDS
