Atenção precoce do câncer de mama :um olhar sobre o cotidiano institucional de uma unidade de saúde de Natal

Breast cancer has been considered a grave global public health problem due to its increase in incidence, in women s mortality and in the amount of financial resources spent on the therapeutic interventions used in the treatment of this neoplasia. However, this scenario presents some variations. In developing countries, the incidence of breast cancer is increasing but, on the other hand, the mortality is declining among patients because of public health actions toward early diagnostic that also result in cure of patients and decreasing levels of physical and psychosocial stress. In Brazil, we face of both the increasing number of breast cancer incidence and number of mortalities. Almost always the reason for that is a delayed detection that will provide a late diagnostic. The early detection of breast cancer has been studied in several researches. Some of them are concerned with women s experiences. Despite that, there is a lack of researches on dynamic comprehension of early attention to breast cancer from the health professionals points of view. The present research was carried out at the Unidade Mista de Felipe Camarão (UMFC) and it was conducted with 11 professionals who work in the Family Health Program (PSF). The aim was to understand how early diagnostic and attention to breast cancer is being planned, discussed and accomplished by health professionals in their day-to-day actions. Semi-structure interviews were held individually with each professional, in a way that they could feel free to express their ideas about several issues. All the information from these interviews was analyzed and discussed using an Institutional Ethnographic approach. It was observed that the actions of health professionals working with early detection of breast cancer does not take place in a vacuum; they occur within institutional, relational and social ways. This interdependence influences their actions and points of view on the theme

Síntese e caracterização de materiais nanoporosos para pirólise catalítica de óleos pesados

The present work reports the study of nanoporous structures, aiming at their use in research directed to the current demand of the petroleum industry to value heavy oil. Initially, two ways were chosen for the synthesis of porous structures from the molecular sieves of type Si-MCM-41. In the first way, the structure MCM-41 is precursory for heteroatom substitutes of silicon, generating catalyst of the type Al-MCM-41 from two different methods of incorporation of the metal. This variation of the incorporation method of Aluminum in the structure of Si-MCM-41 was carried out through the conventional procedure, where the aluminum source was incorporated to the gel of synthesis, and the procedure post-synthesis, where the Aluminum source was incorporated in catalyst after the synthesis of Si-MCM-41. In the second way, the MCM-41 acts as a support for growth of nanocrystals of zeolite embedded in their mesoporous, resulting in hybrid MCM-41/ZSM-5 catalyst. A comparative analysis was carried through characterizations by XRD, FTIR, measures of acidity through n-butylamine adsorption for TGA, SEM-XRF and N2 adsorption. Also crystalline aluminosilicate with zeolitic structure MFI of type ZSM-5 was synthesized without using organic templates. Methodologies to the preparation of these materials are related by literature using conventionally reactants that supply oxides of necessary silicon and aluminum, as well as a template agent, and in some cases co-template. The search for new routes of preparation for the ZSM-5 aimed at, above all, the optimization of the same as for the time and the temperature of synthesis, and mainly the elimination of the use of organic templates, that are material of high cost and generally very toxic. The current study is based on the use of the H2O and Na+ cations playing the role of structural template and charge compensation in the structure. Characterizations by XRD, FTIR, SEM-XRF and N2 adsorption were also conducted for this material in order to compare the samples of ZSM-5 synthesized in the absence of template and those used industrially and synthesized using structuring

O uso de analogias para o ensino de equilíbrio químico no ensino médio: facilitação da aprendizagem ou transmissão de erros conceituais?

The use of analogies in high school is often useful for chemistry teaching, either on textbooks or by teachers in the classroom.This use is justified by the large number of abstract concepts that rules this course. Analogies are conceptualized by several authors, which converge on the idea that these are tools that seek a way to elucidate an unknown concept by comparing it to a familiar one, relating their similar and dissimilar features. An analysis on a survey of analogies found in high school chemistry textbooks and chemical equilibrium studies is performed in order to verify whether they are leading to misconceptions for their use by students and/or for their use by teachers in the classroom, or whether they promote a learning facilitation

Síntese de catalisadores nanoporosos na ausência total e parcial de direcionadores orgânicos para pirólise catalítica de óleos pesados e intermediários

The processing of heavy oil produced in Brazil is an emergency action and a strategic plan to obtain self-sufficiency and economic surpluses. Seen in these terms, it is indispensable to invest in research to obtain new catalysts for obtaining light fraction of hydrocarbons from heavy fractions of petroleum. This dissertation for the degree of Doctor of Philosophy reports the materials preparation that combine the high catalytic activity of zeolites with the greater accessibility of the mesoporosity, more particularly the HZSM-5/MCM-41 hybrid, done by synthesis processes with less environmental impact than conventional ones. Innovative methodologies were developed for the synthesis of micro-mesoporous hybrid material by dual templating mechanism and from crystalline zeolitic aluminosilicate in the absence of organic template. The synthesis of hybrid with pore bimodal distribution took place from one-single organic directing agent aimed to eliminate the use of organic templates, acids of any kind or organic solvents like templating agent of crystalline zeolitic aluminosilicate together with temperature-programmed microwave-assisted, making the experimental procedures of preparation most practical and easy, with good reproducibility and low cost. The study about crystalline zeolitic aluminosilicate in the absence of organic template, especially MFI type, is based on use of H2O and Na+ cation playing a structural directing role in place of an organic template. Advanced characterization techniques such as X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Highresolution Transmission Electron Microscopy (HRTEM), Adsorption of N2 and CO2, kinetic studies by Thermogravimetric Analysis (TGA) and Pyrolysis coupled to Gas Chromatography/Mass Spectrometry (Pyrolysis-GC/MS) were employed in order to evaluate the synthesized materials. Achieve the proposed objectives, has made available a set of new methodologies for the synthesis of zeolite and hybrid micro-mesoporous material, these suitable for catalytic pyrolysis of heavy oils aimed at producing light fraction

A Central Única dos Trabalhadores (CUT) no embate das contrarreformas da previdência social: contraposição ou consenso?

The provident rights were results of intense fights in between the capital and work, claiming the interventions of the state for the creation of an ample social protection system. In Brazil the law, Providence Social mark, dated 1923, from then on, the advances and extensions were many, of this diverse categories of politics. Mean while, in the 1990 s, the Brazilian government adopted the examples of other developed countries, the new pattern that hinted the realization of substantial changes on the states purpose, the reached rights and the proper organization of working classes. For the Social Providence, the principal loses turned out in 1998 and 2003; respectively in FHC governments and Lula, with the realization of two counter reforms that restricted the provident rights and motivated the privatization of public providence. In the scenery, the CUT, one of the representative organizations from working classes, founded in 1983, that has always itself with changed direction, from fighting to negotiating. This inflection determined the proposition of the center before the offers of the counter reforms, of Social Providence. The present work has the objective to analyze the social politic content of the fights from Brazilian union movement in the period of the conquests and disassembled rights and, to analyze the proposition, acting and offers from CUT in the counter reform period from Providence in the Government FHC and Lula. To perform this study beyond the essential bibliographical revision to found and deepen the subject, we use, the documental search through the internet pages, resolutions, informations and others publications from CUT. Using CUT in the governments worked in an elegant way, the FHC government against-reforms, showed itself through diverse actions, even though they didn t have homogeneous inside, contrary the neoliberalists politicians from this government, also the offers and precaution changers. While during the reign of Lula it shoved itself priority negociative and propositive

Saúde do trabalhador: entre os dispositivos legais e as práticas efetivas

The health worker is seized in this research beyond the mere applicability of legal devices concerning the legislation of Labor, in order to be established correlations with activities alluding to the public power in the ambit of State of Rio Grande do Norte (RN). This dissertation is an cutting of analysis circumscribed in the research, "Accidents at work: law, citizenship and justice," of the Grupo de Estudos Seguridade Social e Trabalho (GESTO) of Universidade Federal do Rio Grande do Norte (UFRN). The overall goal turned to apprehend and relate contradictory elements inherent compliance of Occupational Health and Safety (OHS) in the supermarket which showed the highest occurrence of legal violations recognized by the Labor Justice of RN in the period between 2006 and 2008 . The specific objectives turned to identify, from the condemnatory sentences, violations inherent in the protective direction of the OH & S legislation; analyze the relationship of health damages to workers at the supposed recognition of rights claimed in condemnatory sentences and correlate violations inherent in the legislation OSH impacts on the health of workers, from data contained in expert reports. The justification for perform the research backed up, among other factors, in the fact that class of activity has been presented as the most recurrent in condemnatory sentences, since it chose to focus the analysis on documentary evidence from the supermarket which showed greater expression in relation to violations of the OSH legislation. From a qualitative perspective, the methodological approach was based on content analysis of thirteen condemnatory sentences, handed down by the potiguar labor justice, and three expert reports from a large supermarket in the city of Natal/RN. Aftermaths are evidenced relating to the cyclical processes of reorganization of capital, demanding requirements for labor organizations whose strategies for survival include identifying mechanisms to extract as much of the work force. Structural determination and ideological context that puts into question the historical achievements of workers, for example the legal devices aimed at preventing workplace accidents, expressed in this research as relativized, showing limitations of reach, as was inferred the indemnities, by material and moral damages, arising from Work-Related Musculoskeletal Diseases (MSDs'S), recognized by the laborite judiciary

Mídia e gênero: análise crítica da violência contra a mulher no telejornalismo

This thesis is consisted of a theoretical and empirical study about the treatment given by media, particularly on telejournalism, to violence against women. It aims to analyze and reflect about the role of media, particularly television, on the process of reproduction of patriarchy system of gender on the context of Brazilian society, from content and narrative news about crimes committed against Andreia Rodrigues and Eliza Samudio. In light of the critical perspective, we seek to apprehend the particularities of patriarchy as a system of domination and subjugation of women, and also reveal the involvement of traditional means of media on reproduction and maintenance of inequality between men and women. To apprehend that reality, we had as guidance a critical social theory, grounded in historical-dialectical materialism which enabled us to apprehend the phenomenon under investigation actually enrolled in a dynamic and contradictory reality. The research had qualitative approach. We appeal to the specialized literature of the area from classical and contemporary authors. We conducted a content analysis of categorized matters, and interviews with individuals involved in issues of gender and / or communication. The critical examination of the matters indicated that television journalism is permeated by the contradictions inherent in social life, means that states and restates the ideology of ruling classes, their values and worldviews, but also express conflicts and social demands. The study revealed that prevails on television playing stereotypes and gender inequalities. We could also see that violence against women gets a sensationalist overblown approach and with no insights on the social relations that determine and base it.

Violência e luta por direitos no capitalismo contemporâneo: crítica à configuração do atendimento às mulheres no Rio Grande do Norte

This research analyzes the Rio Grande do Norte care services to women who face violence in the context of contemporary capitalism. To do so, we situate the patriarchy in the set of current social relations and its relationship with the corporate determinations in everyday life. The new functions of the Patriarchy in the capital sociability permeates the lives of individuals and particularizes the relationships of violence which affects women, requiring, in the immediate level, policy-making to face them. The research found an arsenal of contradictory possibilities and limitations in dealing with violence. In this process, forms of struggle and resistance predominate, which appear as possibilities and limits were identified relate to the socio-historical context of regression of the rights, historical moment in which increase the objective difficulties in everyday life to ensure the legal achievements. It is worth to emphasize the achievements and contradictions that characterize the struggle process for rights, linking services to women to the social policies and to the limits they face in opposition to the aims of the State to meet the mandatory requirements of capital, reducing its role as the main guarantor of policies and rights. In this sense, the trajectory of the achievements that have referred to the proclamation of a specific law to deal with combat violence against women, the Maria da Penha Law - 11.340/06, which provides an integrated set of measures that, if implemented, would allow the women protection from relations of violence they experience. We identified in Rio Grande do Norte precarious services that are essential to achieve the Maria da Penha Law. This situation requires a feminist organization to claim the rights that enable women to see themselves as people with rights in the process of collective struggle. This is the historical need for continuity of struggles that accumulate policies for the existence of a new model of social relations of gender. One of the possibilities that are presented in the current context is the impact on the public budget in order to ensure compliance with the budget for public policies for women - woman budget. In this perspective, feminist segments in national and state level have been organized to understand the functioning and monitoring of social policies. This is a condition and prerequisite for ensuring policies to ensure basic rights and the violence combat , which still requires an integrated set of services. The survey results allow us to consider that the struggle for rights is necessary at this historical moment, however it is not sufficient in human emancipation, which requires new forms of social relations that determine substantive equality between men and women. Thus, the feminist movement faces the challenge to organize and strengthen itself in daily life, in order to execute a project that changes the meaning of women's rights, articulated to a corporate project which wants other command in the set of social relations . This study emphasizes the need for a more and more organic connection between feminism and social struggles, to ensure the inclusion of women in anti-capitalist struggle

O PEATE nesta população permite um melhor direcionamento da conduta e intervenção e aconselhamento específico aos familiares.

Geração automática de testes a partir de descrições de linguagens

Some programs may have their entry data specified by formalized context-free grammars. This formalization facilitates the use of tools in the systematization and the rise of the quality of their test process. This category of programs, compilers have been the first to use this kind of tool for the automation of their tests. In this work we present an approach for definition of tests from the formal description of the entries of the program. The generation of the sentences is performed by taking into account syntactic aspects defined by the specification of the entries, the grammar. For optimization, their coverage criteria are used to limit the quantity of tests without diminishing their quality. Our approach uses these criteria to drive generation to produce sentences that satisfy a specific coverage criterion. The approach presented is based on the use of Lua language, relying heavily on its resources of coroutines and dynamic construction of functions. With these resources, we propose a simple and compact implementation that can be optimized and controlled in different ways, in order to seek satisfaction the different implemented coverage criteria. To make the use of our tool simpler, the EBNF notation for the specification of the entries was adopted. Its parser was specified in the tool Meta-Environment for rapid prototyping

Competitividade de destinos turísticos e o imperativo sustentável: avaliação de dimensões e atributos condicionantes no Pólo Costa das Dunas, RN, Brasil

Being available as a tourist destination is a necessary condition but not enough for the expansion and success of tourism activity. To be successful, tourism requires investment, inputs, appropriate planning and management, like any other economic activity. A fundamental goal of the destination management is to understand how the competitiveness of a tourist destination can be improved and sustained. Competitive position of tourism can be measured and assessed by various models. Evaluating the indicators of competitiveness of a tourist destination involves a multivariate analysis, ranging from issues directly related to tourism activity itself to the indirect factors. These are elements that are interrelated and that together will point out the competitive condition of this destination. From the definition and characterization of competitiveness, sustainability and management in the context of tourist destinations, understood as the main concepts of this study, we present the main theoretical and methodological models of assessment of competitiveness of tourist destinations in the literature and represent the state of the issue in the scientific treatment of the subject. These models, designed by researchers from several countries and applied in different tourist destinations, are confronted about their structure, indicators considered and localities in which they were applied. The aim of this study was to know and evaluate the condition of tourist competitiveness of the destination Pólo Costa das Dunas, from the constraints attributes of superior performance of the evaluation model of tourist competitiveness of destinations Competenible, suggested by Mazaro, and that suit the requirements of international market aware of the strength and importance of sustainability. The condition of competitiveness of tourist destination in Rio Grande do Norte Pólo Costa das Dunas was moderate. The competitive strengths and weaknesses of the destination Pólo Costa das Dunas revealed through the dozens of sustainable attributes of the model Competenible showed guidelines and initiatives that can be taken to guide strategic decisions related to their planning and management. Thus, this study should serve as support for strategic planning and long-term management of the sector and as a crucial tool for making decisions related to public policies, sectoral investments, monitor processes, strategic planning, direction and control of the local and regional tourism development of destinations

Autoimmune thyroid disease as a risk factor for angioedema in patients with chronic idiopathic urticaria: a case-control study

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Caracterização epidemiológica e demográfica de homens com câncer de próstata

O estudo pretende identificar características demográficas e epidemiológicas em homens com câncer de próstata, atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu/UNESP, entre 01/01/2000 e 31/01/2003. Foram colhidos dados em 78 de 94 prontuários, observando-se escolaridade, uso de tabaco, estado civil, idade, diagnóstico e sintomatologia. Utilizou-se metodologia quantitativa associada à estatística descritiva. Foram encontrados 50% com 1º grau incompleto, 27,39% não tabagistas, 87% casados, 43% entre 64 e 73 anos. Observou-se que 27,58% foram diagnosticados em 2000, sendo 63,20% aposentados e 20,70% com sintoma de jato urinário fraco. Apenas 20% tinham realizado exames preventivos e, desses, 77,90% possuíam 1º grau incompleto. O estudo foi feito nesse hospital por ser considerado de referência terciária da Direção Regional de Saúde de Botucatu -DIR XI¹. da amostra, 80% procuraram o serviço apresentando sintomas, o que leva a crer que ainda haja falta de orientação da população quanto ao câncer de próstata, principalmente quanto à incidência e prevalência relacionadas à idade, como fator de risco. O estudo evidencia subsídios para um melhor direcionamento da assistência a esses pacientes, permitindo um diagnóstico precoce e conseqüente possibilidade de cura, além da melhora na qualidade de vida.
