A saúde do trabalhador na atenção básica: concepções e práticas dos enfermeiros

This study aims to analyze concepts and practices developed by nurses in occupational health in primary care, and it is justified by the need to expand knowledge of this thematic area. This is an analytical qualitative study carried out in primary care units of health districts of the city of Natal-RN, in one health unit in each neighborhood. Data collection was held from August to October 2014, through semistructured interviews, in the following order: Selection of respondents and scheduling of interview; interviews and application of data collection instrument in order to trace socio-demographic profile of the target population; transcription of interviews; categorization of information and analysis in light of hermeneutic-dialectic. The concept of Occupational Health reported by subjects investigated, although simplified with respect to specificities of workers, was revealed with a wide dimension, with perspective of workers’ approach in their physical, mental and social context, suggesting a good seizure according to the expanded concept of health. Furthermore, it was possible to affirm the recognition of an incipient performance of primary care nurses on Occupational Health, whose performance was appointed as defective. In general, some specific actions of Occupational Health, carried out in health facilities, were cited. Other activities showed up to be routine, being held by a minority of professionals aware of the importance and need to reach these users, in order to engage them in the routine of the health unit. Most professionals reported not having approached Occupational Health during undergraduate nursing, highlighting a lack in theoretical and practical aspects of the area

Conhecimento de si e unidade: considerações sobre a alma em Plotino

L'obiettivo di questa tesi è quello di sviluppare una analisi dell'idea dell'immortalità dell'anima dalle Enneadi di Plotino attraverso la comprensione del discorso dell'anima come eterno, e unità-pluralità ricerca di semplicità con la Uno sulla temporalità del corpo multiple. Per fare ciò, abbiamo iniziato cercando di analizzare brevemente le plotinianas ipostasi (l'Uno, lo spirito e l'anima) per stabilire meglio le basi del pensiero di Plotino quando si discute l'idea dell'anima e la sua immortalità. Cerchiamo di esaminare il pensiero epistéme di Plotino e la sua dialettica, al fine di sviluppare una comprensione del rapporto tra materia e forma sensibile e intelligibile. In questo modo, si sviluppa nelle Enneadi di Plotino il ruolo fondamentale del Logos e il Logoi nella formazione dell'anima. Analizziamo anche la processione (Proódos) e ritorno (Epistrophé) le implicazioni degli aspetti dell'eternità sulla purificazione dell'anima nella temporalità del corpo. Cerchiamo in ultima analisi, l'idea dell'immortalità dell'anima dalla conoscenza stessa immortalità sulla semplicità di Colui, cioè, l'ultima volta che la ricerca della conoscenza di sé dalla dimenticanza di sé per è solo con l'Uno: il "Elimina ogni cosa" (Aphele pánta).

Promoção da alimentação saudável na atenção primária à saúde: contribuição para construção coletiva do saber-fazer

The recognition of the food as determinant and health-disease process etching requires new explanations and interventions of the food and nutrition policy action and demand health care model based on the completeness of the actions and focused on health promotion. This study, characterized as research-action of interventionist character, sought to develop strategies to support the transverse insertion of healthy eating promotion in professionals practices a core of support for the health of the family and a family health strategy Unit in the city of Natal, capital of Rio Grande do Norte, from the analysis of perceptions and work processes of these teams. Several methodological strategies were adopted: Dialectical Hermeneutical Circle, direct observation, reflective and Thematic Meetings Workshop "Rethinking the educational practices for promoting healthy eating". For data logging, search diaries - SD were used and moments. The analysis of procedural form occurred in conjunction with research participants, in constant movement of reflection-action-reflection, based on hermeneutics-dialectic. About the results, in relation to the promotion of health, showed the following insights: health promotion and disease prevention-related harms; health promotion related to quality of life and well-being, in its various dimensions; health promotion as a responsibility of the State; health promotion related to the actions of health education; health promotion as an expression of efficaciousness and accessibility to health services. Regarding healthy nutrition, predominated the perceptions relating to nutritional aspects. With regard to food and nutritional education - FNE, it was observed a predominance of perception of FNE as information, guidance and knowledge transfer for changes of dietary practices. As regards the working process, it was observed that among the actions for health promotion, educational activities predominate, such as lectures, conversations, groups that mostly occur in fragmentary form, without joint planning teams, varying according to the professionals and the moment of work in which they are carried out. The results pointed to the need for reorganization of the work processes, in the context of intra-and intersectoral coordination and the construction of new technologies, such as: Health project of the territory – HPT, Unique Therapeutic Project- UPT, Expanded Clinic and educational practices, Shared with active teaching and learning methodologies. From the results we believe that it is necessary to "thought reform", from changes in vocational training and strengthening of the permanent education spaces, whereas the complexity that involves feeding, food and nutrition education and health promotion. The reformation of thought must be articulate and closely tied to the production of knowledge and practices that encourage intersectoral approach, the transversality, dialogue and democratic and supportive attitude, based on the collective construction of know-how. We hope that this study can contribute with reflections and initiatives that encourage building practices that promote healthy eating in primary health care, in terms of completeness of the care and the attainment of food security and nutrition.

O registro de procedimentos metodológicos em projetos de intervenção arquitetônica no patrimônio edificado: o caso de Natal-RN

In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

A compreensão de reação química como um sistema complexo a partir da discussão dos erros e dificuldades de aprendizagem de estudantes do ensino médio

The study of chemical reactions is among the most important contents to the understanding of Chemistry discipline in basic education. However, there are still few studies about chemical reactions as a complex system because, generally, this content is presented in textbooks, taught and even researched in a fragmented form. The thesis here presented aims to investigate, identify and characterize the mistakes and learning difficulties of the students about chemical reactions as a complex system, using for that purpose the analysis of the answers of 126 exams of candidates for the bachelor’s degree in Chemistry Teaching on the entrance exam for the Federal University of Rio Grande do Norte (UFRN). The mistakes and learning difficulties about the parameters ΔG°, Kp, Ea and of the calculation of the amount of substance in a chemical reaction have been identified, as well as the levels of development of the ability to interpret the chemical reaction as a system. The main theoretical source of this study is structured based on the mistakes and learning difficulties (NÚÑEZ, RAMALHO, 2012), of the chemical reactions as complex systems (NÚÑEZ, 1994; RESHETOVA, 1988; SANDERSON, 1968). As methodology, it was prioritized the analysis of the answers to the exams and the interview with the teachers. The results showed typical mistakes in the study of this subject, especially low levels and skill development. No student was able to integrate the different aspects in the systemic understanding of the chemical reaction. From the interviews with Chemistry teachers from High School, it was determined the reasons the teachers assign to those mistakes and learning difficulties. The interviews revealed that the teachers do not work in the perspective of integration of the contents which leads the students to present difficulties and make mistakes related to the content previously mentioned. The study presents a proposal for the organization of the contents of Chemistry discipline for High School as a possibility of a dialectic systemic integration of contents, understanding that this systematic vision, leads to important contributions to the development of the theoretical thinking of the students. We can mention as one of the conclusions of this study, the fact that the non-systemic organization of contents do not favor this kind of thinking in students.

Mil cenários: Deleuze e a (in)atualidade da filososfia

Evidentemente, como todas, a filosofia de Deleuze será sempre menos do que exigimos ou esperamos dela, mas também muito mais do que lhe concedemos ou dizemos da mesma. No que tem de vivo, de vital, a obra de Deleuze não deixa de provocar fugas em todos os comentários que perseguem sua totalização à conta de uma imagem, de uma doutrina ou de uma data. Não há «um» Deleuze, radicalizado à força de privilegiar o que tem de irredutível com relação aos diferentes horizontes de leitura. Mas também não existem «dois» Deleuze, desdobrados segundo uma dialética de apropriação que requereria, para a salvação de um punhado de princípios, o anátema de parte de sua filosofia. Digamos, antes, que há «pluralidade» de conceitos, de perspectivas e de textos, que associamos ao nome de Deleuze, mas sempre de um modo local, estratégico, essencialmente aberto. Na sua determinação propriamente deleuziana, a história da filosofia não tem por objeto restaurar o sentido profundo do que os autores teriam dito para nós, mas apenas extrair um duplo. E, com os duplos, já se sabe como é: nunca estamos seguros de quem é quem. Os desiguais textos que compõem o presente livro não pretendem desmascarar impostores, mas multiplicar os espelhos.

Integração ensino e serviço: dizer e fazer saúde na atenção básica

The current discussion on Education and Health has shown the need for greater integration between health services and academia, and this issue has been addressed by researchers in the area as being of great importance. How do we say what we need to do? The National Policy on Education Permanent Health proposes the dissemination of pedagogical skills at SUS, so that the public health clearance to constitute an area of teaching and learning in work performance. This study aimed to know how is the process of integration between education and health services in primary health care, from the knowledge on the role of mentors in the training of undergraduate students in the healthcare field in UFRN. Qualitative Methodology possible, from the use of the techniques of Semi-Structured Interview and Direct Observation of achieving this goal. The analysis of data taken from the Hermeneutic-Dialectic Approach, taking as mediators knowledge of the areas of Education, Health Education and Public Health, showed that the performance of preceptors constitutes an important strategy to enable the integration of teaching and service, and the professionals involved in the preceptorship educate themselves while they educate. The educational process is permeated by knowledge and experiences heterogeneous, highly favorable to the training of students and professionals factor. Innovative educational practices proven capable of starting the mediation of preceptors and other professionals involved in the Work Programme Education for Health, extend learning. The curriculum components Integrated Activity of Health, Education and Citizenship, and Tutorial Program for Integrated Health Work chosen as the basis for this experiment set, for preceptors, the need to seek new knowledge, allowing each actor transcend its specific area of academic training and interact with other areas, which makes learning interesting, enjoyable and meaningful.

Processos de imitação-criação como constituidores da práxis pedagógica: uma intervenção didático-formativa com o formador de professores

The research deals with the constitution of the pedagogical praxis of a teacher trainer, understood as objectification of theoretical and practical unity in the teaching field. It was achieved by means of a didactic-training intervention. The research problem: as a teacher trainer in a continuous training process is a pedagogical praxis, outlined to the overall objective: investigate the establishment of the pedagogical praxis of teacher trainer in a continuous formation process. The specific objectives were: 1) outline principles and foundations theoretical-methodological course of intervention research on appropriate teaching assumptions of historical-cultural theory; 2) systematic principles of constitution of the pedagogical praxis of a teacher trainer and 3) synthesize foundations of continued training of teacher trainers in view of the historical-cultural theory, to collaborate with design of institutional policies for continuing training of university teachers. The research was developed at the Federal University of Triângulo Mineiro University - UFTM, with teachers who work in their degree courses. It was developed in three stages: diagnosis, didactic-formative intervention and analysis of data. In the diagnostic step attended five teacher educators of degrees in: history, geography, physics, chemistry and letters. At this stage were used identification questionnaires, interviews, classroom observation and document analysis. In the next stage, with participation of a trainer, it was held educational-training intervention understood as the collective research-training process that is involved intervening in teaching with the development of interdependent and simultaneous actions trainings, planning and implementation of educational activities and study, classroom observation and evaluation from the perspective of dialectical unity in order to contribute to the integral development of teachers and students. The intervention were also held interviews and document analysis. The last stage of the research was the analysis of the data. In the diagnosis of education, among other analyzes, three references were found of the trainer's training-action: memorized references, empirical and praxis. It was the analysis of the references of the trainer's training-action that guided referrals ways of teaching-training intervention. As a result, it was concluded that the teacher educator is their pedagogical praxis in the dialectical units theoretical and practical appropriation of concepts and imitation-creation. Were the two principles analyzed in the research. It was also systematized some essential elements of the formation of the teacher educator: the needs of trainers are decisive in the choice of concepts that will be appropriate; the organization of the training process should take place hand in hand with planning and development classes; the theory need to be experienced in training so that appropriation/objectification of education come true, and also, participants must be strengthened as a collective studies, since we have not learned by linearity but connections. It is hoped that the research will create opportunities to deepen the debate on the continuing education of teacher educators and contribute to scientific production in the area.

A concepção de trabalho escolar a partir de Maurício Tragtenberg: fios e tramas de debate na (des)politização dos sujeitos sociais

This thesis, part of the research line "Work, Society and Education" analyzes, in a dialectical perspective, in the light of Tragtenberg´s studies, the conception of subject of schoolwork, considering the organization and the complexity of this context and inviting the investigative gaze. Our hypothesis is that the workers of education have, in the schoolwork, a fragile politicization field and overcoming the installed model, accepting themselves as executers with self-organizing difficulties, distanced from the effective participation, autonomy and self-management. We consider studies on the logic of the work, believing that the understanding of schoolwork is constitute into the current societal model, in whom its bureaucratic and hierarchical matrix, linked to articulated / articulators of the dominant socio-economic class interests. Scholars such as Braverman, Frigotto and Tragtenberg, among others, are important contributions to this reflection. We have analyzed the logic of the work also in dialogue with pedagogies differentiated, among them, the Libertarian defended by Tragtenberg, aiming to understand the conceptions and practices of the subjects involved. We accomplished a bibliographical critical analysis, in a dialectical character, focusing on the categories: work, schoolwork, control, autonomy and self-management, in order to understand the complexity of the praxis in study, dialoguing with the pillars categories historicity, contradiction and totality, which transversalize the developed analysis. The consideration of these concepts allows us to uncover the dominant bureaucratic structure and its possible overcoming fields. We believe contribute to problematizing and proposers studies, reflections and discussions, strengthening debates, deconstructing naturalizations and contributing to the political process of the subjects.

Concepções de administração e administrador em tempos de capitalismo flexível: uma abordagem crítica

A tese trata de dois construtos sócio-históricos Administração e Administrador em face do capitalismo em sua fase flexível. Considerando as mudanças do capitalismo, o texto estabelece como objeto de estudo as concepções de Administração e Administrador, para o campo administrativo, na contemporaneidade. A tese é suportada por uma pesquisa de campo cujo objetivo foi compreender criticamente as concepções do campo administrativo sobre a Administração e o Administrador, em tempos de capitalismo flexível. Epistemologicamente, a pesquisa foi conduzida a partir da perspectiva crítica frankfurtiana, fundamentada em três pares categóricos dialéticos: (i) história versus naturalização; (ii) práxis social versus sistema; e (iii) alienação versus emancipação; privilegiando o pensamento crítico vinculado à primeira geração da Escola de Frankfurt. A literatura prevalente da área de Administração foi revisada mediada pelas duas questões ontológicas que suportam a tese: O que é Administração? e O que é Administrador? para autores como Taylor, Fayol, Drucker, Ohno, Deming, Champy e Mintzberg. Metodologicamente, foi realizada uma pesquisa integralmente qualitativa, com uso de três tipos de entrevistas: (i) entrevista narrativa com história de vida; (ii) entrevista com uso de elementos-estímulo; e (iii) entrevista narrativa ficcional. Para compreensão das narrativas, foi utilizada a técnica de análise hermenêutico-dialética. Os resultados indicam o predomínio da concepção pragmática-instrumental, no tocante à Administração, pela qual ela continua a ser pensada e discursada como uma ação tecnológica e teleológica, que utiliza saberes múltiplos e aprendizagens cambiantes como meios para alcance das finalidades do contexto organizacional mutante. Com relação ao Administrador, há a emergência da concepção estética para apresentá-lo, quando vinculado às organizações. Por esta concepção, há a migração do histórico estereótipo do Administrador controlador e vigilante para a representação do Administrador como um profissional performático. O segundo resultado, que se apresenta como o mais relevante em relação ao Administrador, é o da fuga da profissão. A partir dos pares categóricos dialéticos, esta tese propõe algumas sínteses provisórias críticas: (i) história-naturalização: os sujeitos tomam como naturais a organização empresarial e suas demandas, naturalizando as recentes mudanças que, entre outras coisas, reduzem os postos gerenciais; (ii) práxis social-sistema: pela concepção pragmática-instrumental, as experiências dos Administradores são concebidas a partir do confinamento funcionalista em uma organização-sistema; (iii) emancipação-alienação: tanto a forma naturalizada com que especificam as organizações e sua Administração quanto a práxis interrompida velada em uma experiência reificada mostram-se como fenômenos intrinsecamente e subjetivamente alienantes e contraemancipatórios. Por outro lado, através do movimento de fuga da profissão, os entrevistados parecem (re)significar o silêncio fundador da alienação associada à condição de Administrador: a de pensar como capital, e não se pensar como trabalho. Finalmente, o texto propõe que as possibilidades de emancipação deste profissional residem na tomada de consciência de sua condição como integrante da classe trabalhadora, mesmo em tempos de riscos e incertezas. Assumindo-se como trabalhador, o Administrador poderá lutar pelo seu trabalho, repensando-o em novos termos, em que as dimensões pragmáticas-instrumentais que envolvem sua profissão possam ser dosadas e sempre mediadas por conteúdos substantivos e emancipatórios

Vigilância eletrônica no trabalho bancário: do controle consentido ao totalitarismo corporativo

This dissertation addresses the electronic surveillance theme in the banking context. The research that originated it, which was held in an organization called for the fiction name Banco Total, started from the following driving question: How do workers at a bank perceive electronic surveillance at their process of work? The research s main objective was to comprehend how workers perceive electronic surveillance at their process of work. The study adopted an interdisciplinary perspective, having Management as the original field, establishing a dialogue with others disciplines, like Philosophy and Sociology. About its methodology, it s a qualitative research that addressed its object in oral (interviews with live history elements) way. . Ten individuals were interviewed. The analytical process utilized the hermeneutical-dialectics technique.. From the analyses (hermeneutics) of the data, the following themes have emerged: (i) Acquiescence ; (ii) Monitoring; (iii) Time and Motion; (iv) Fear; (v) Interdiction; and (vi) Resistance . From the discussion (dialectic) of the results, this work presents three synthetic propositions that culminate in the following dimensions (i) control; (ii) acquiescence; (iii) corporative totalitarianism. It can be concluded that electronic surveillance is one mechanism of control emerged from the apply of technology at Total Bank; that information technology has been improving the control mechanisms of management theories; and that the imbrications between management and material technology control mechanisms at a context where there is acquiescence by workers contribute for the emergency of corporative totalitarianism components

Centros históricos e desenvolvimento urbano: um estudo comparativo entre os programas Monumenta no Brasil e Polis em Portugal

Both the end of the twentieth century and the beginning of the twenty-first century have been characterized as a period of major political, economic, social and cultural transformations. Two of the major consequences of the political-economical crisis of the end of last century are the restructuring of capitalist production, and the consolidation of neoliberalism as a worldwide phenomenon. This new world political-economical scenario has influenced, in a dialectic way, the contemporary urban development. In that sense, "new" spatial processes and new paradigms in both urban management and urban planning have gained shape. In this context of urban transformations, the central areas of western cities, also known as historic centers, are being increasingly (re)valued. Since the Second World War, the historic centers urban areas which have great infrastructure and symbolic relevance had been undergoing a process of evasion of population and activities, undeniably linked to the neglect of government authorities. However, in recent decades, the question of historic centers rehabilitation has acquired a growing interest, academically and in political agendas. The object of this dissertation is to focus on how the government of each Brazil and Portugal has dealt with the issue of historic center rehabilitation through programs of urban rehabilitation

Educação ambiental no curso de técnico de edificações - ifsul campus Pelotas : desafios e possibilidades da educação emancipatória nos cursos técnicos

O presente trabalho de dissertação de mestrado visa a descortinar as contradições que estão presentes nas representações de docentes e discentes da disciplina de práticas construtivas do Curso Técnico de Edificações, do Instituto Federal Sul-Rio-Grandese (IFSul), campus Pelotas, em suas relações sócioeducativas, encontrando nesse desvelamento alternativas para o desenvolvimento destas atividades práticas de forma a contribuir na sustentabilidade do curso, e por conseguinte na sustentabilidade das relações entre homens, natureza e meio ambiente. A partir dessas representações sociais e contradições, esse trabalho possibilitou, através de um estudo de caso de natureza qualitativa dialética, de posse das categorias do Materialismo Dialético e Histórico e da economia política, uma compreensão dialética de como o modo de produção capitalista interfere nas ações em geral, inclusive nas relações de educação. A opção por esse assunto foi principalmente devido a constatações próprias, como professor de práticas construtivas, da necessidade de continuidade das atividades práticas no curso, mas de uma maneira mais coerente com as leis da natureza, por um processo educativo emancipador de educadores e educandos, socializando os saberes libertadores da educação ambiental. O estudo mostrou-se coerente e revelador materializando-se em possibilidades, projetos e ações imediatas de transformações dentro do curso de maneira a interferir nas relações de todos entre si e com a natureza, com uma forma possível de utilizar as matériasprimas necessárias sem o desperdício, com o máximo de aproveitamento e reciclagem, com a possibilidade de levar essas aulas práticas para fora dos muros da escola, em atividades necessárias para entidades assistenciais, minimizando a geração de resíduos sólidos a serem descartados na natureza, contribuindo dessa maneira com o perfeito relacionamento homem-homem, homem-natureza, na busca da sustentabilidade e na conservação da vida no Planeta.
