Uma nova tecnologia no pensamento de Herbert Marcuse: arte e técnica na sociedade unidimensional

This dissertation addresses the issue of technology in the work of Herbert Marcuse, explaning the merger between technology and domination that result in a totalitarian technological apparatus. Thus, technological civilization is supported and justified by a rational technological apparatus in the society, we have come not only the philosophy of Marcuse, but other great thinkers too, like Heidegger, Hegel, Marx. We also present a debate involving the philosophy of science, logic and linguage. Marcuse points to the need for a new technological rationality that emerge from a new sensibility, where the technique would allow a new relationship between man and nature. From then on, would emerge the need for a new subject. This transition would be possible by means of sensitivity, where art would become the art of live. With the link between art and technique made possible by new sensitivity, the author leaves one of its main contribution: he leaves open the possibility for the subject to choose new targests for technological development

Os significados do tabagismo construídos na dinâmica social

The present study has the purpose of catching the significances of smoking in the social dinamics based on the Theory of Social Representations. It was developed among adults with ages from 20 to 59 years, low social and economic conditions, at Natal RN, Brazil. The Free-words Association Test was applied as the instrument of data collection and a semi-structured interview with the smokers and non-smokers, besides a structured interview with smokers, non-smokers and ex-smokers. All data was analyzed by the descriptive statistics using the Analysis of Content Technique of the thematic kind and by the softwares ALCESTE and EVOC 2000. Elaborations about smoking were marked by social, cultural and historical dimension, however they showed sensibility to changes and revealed positive and negative aspects of the habit. The analysis of the semi-structured interviews showed the following categories and under-categories respectively: Initiation of the habit (Friends and Family and Appreciation and Beauty); Psychosocial Implications of smoking (Personal relationship, Work and Financial); Behavior when facing smoking (Positive, Negative and Neutral); Smoking Effects (Smokers´ health and the other people health); Description about oral diseases ( Bad breath, Oral cancer and Dental problems); Smoking treatment (Physician and psychological, Supernatural and Difficulties). ALCESTE analysis presented 4 classes: Ambivalence between pleasure and get ill, Smoking as a trouble and danger to society, Social discrimination of smokers and Mouth as a place of reaffirmation of the discrimination. Those helped us to understand the psychosocial repercussion of the habit. On the social representation structure we identified as a probable central nucleus of the smoker group the categories Pleasure and Bad to the health and as peripheral elements Alcoholic Drink, Financial damage and Nervousness. For the non-smoker group the category Bad to the health comes first and Stop Smoking comes as a peripheral element. Finally, we hope that the knowledge of these representations can contribute to plan and/or to rethink over the professional practices and public policies related to smoking. Besides that, for an amplified comprehension of the study object the discussions over the identified representations should be deepen and amplified to other population and social groups

Estudo comparativo da expressão imuno-histoquímica do ki-67 em carcinoma epidermóide de língua em pacientes jovens e idosos

The squamous cell carcinoma (SCC) is the most common malignant neoplasm of epithelial origin in oral cavity and present high capacity to invade adjacent structures. Traditionally, SCC has a predominance of 50 years male patients with long-time use of tobacco and alcohol, and the tongue is the most affected anatomic site. At present, there is an increasing incidence of SCC in patients below 40 years of age, who has been exposed or not to risk factors, mainly for tongue lesions. This study aims to analyze cell proliferation index using Ki-67 antigen in SCC of the tongue for two groups of different age range: until 40 years and older than 50 years. The first group was composed by 16 patients and the second one was composed by 20 patients. Clinicopathological features of the cases were also assessed. There was a male predominance in both groups. Tobacco and alcohol habits were common for patients until 40 years (72,2%), as well as for patients older than 50 years (52,9%). The first group had statistical association with the presence of regional metastases (p = 0,036) and with the most advanced stages of the disease (p = 0,012). Considering the histological malignancy grading, there was higher incidence (56,2%) of high malignancy grade tumors in the group of patients until 40 years old, but no statistical difference has found between groups and histologic malignancy grading. Regarding the immunohistochemical expression of Ki-67, there was no statistically significant difference between the antibody expression of the groups, as well as between other clinical and histopathological parameters. This study identified no significant difference regarding cell proliferation between the analyzed groups

Masculinidade a prova: um estudo de inspiração fenomenologico - hermeneutico sobre a infertilidade masculina

Culturally, childbearing is understood as a situation that subjects will experience at some point in their lives, especially people who are married or have a similar affectionate relationship. Thus, to realize the inability to meet such a fate seems to be a natural cultural trigger of suffering, frustration and feelings of inadequacy and helplessness. Specifically for men, infertility is closely related to loss of masculinity, virility. He fails in his role as a male. This study sought to understand the impact that infertility have on the existence of a man who receives such a diagnosis, both in self-image as in their marital, sexual and professional roles. This study sets up as a hermeneutic phenomenological research based on the ideas of the philosopher Martin Heidegger. Participants were seven heterosexual, married and infertile men. Two interviews were conducted. The analysis of the material included both the material of the narratives, as the affectation of the researcher when interacting with the participants and their narratives, through phenomenological-hermeneutic interpretation. The results corroborate the literature that states the difficulty of the men, immersed in a context that defines them as virile, powerful and invulnerable to worry about issues related to health and disease. The possibility of any condition that impairs the reproductive capacity exceeds the acceptable limits of daily life for these men, not being recognized as a model of masculinity present in the condition in which they recognize. This leads to questions about their masculinity, role in the marital relationship and their existence. Thus, to recognize themselves as infertile surpass a medical diagnosis and is associated with the construction of meaning for their existence from the approximation with the infertility condition, which helps in redirecting their choices, restoring the project to be self and allowing further recognition as men. In the marital relationship, doing what they can to ensure, theirs happiness. Through these actions, they remain playing the role of family provider, showing that they are able to protect their wives and taking in assisted reproduction or adoption of children viable alternatives to fulfill the desire to leave a legacy and give a child to their wives and to society. Another result observed, refers to the ontological condition of care that characterizes the human being. The ways in which men are treated socially demonstrates a type of care that focuses on the development of characteristics such as strength, virility and determination but does not allow them to cope with the suffering of emotionally difficult situations, such as the diagnosis of infertility. At the end, the study gives rise to reflections on the need to provide a 12 space for men and their expressions of suffering, as well as to recognize their ability to overcome the painful and difficult situations

A água nossa de cada dia : percepção, uso e predisposições comportamentais de alunos do ensino médio de Natal, Rio Grande do Norte

Embora a escassez de água seja reconhecida como um dos principais problemas mundiais a ser enfrentado pela humanidade, padrões comportamentais ecologicamente insustentáveis ainda persistem. Assim, o objetivo deste estudo foi analisar determinantes do comportamento pró-ambiental relativo à água, bem como os significados que lhe são atribuídos por alunos do ensino médio do Centro Federal de Educação Tecnológica do Rio Grande do Norte, em Natal. Compuseram a amostra de conveniência 315 estudantes, 146 mulheres e 169 homens, que responderam a um questionário sobre uso e percepção da água, contendo também indicadores de pró-ambientalismo, cuidado ambiental, desenvolvimento sustentável, perspectiva temporal, externalidades e coletivismo, além de inquérito sócio-demográfico. Para os participantes, água é sinônimo de vida, muito embora a relação que mantém com ela parece dúbia e, muito mais funcional que ecológica; consideram-na um recurso finito, um patrimônio indispensável à vida, contudo não foi observada coerência entre as concepções manifestadas e os comportamentos auto-relatados de uso da água. Os resultados encontrados apontaram preditores importantes do comportamento pró-ambiental relativo à água: sexo do respondente, Escala Novo Paradigma Ecológico e deixar forma de contato para participar de campanhas futuras. Seja para aprofundamento teórico em novos estudos, seja para auxiliar na elaboração de programas de educação ambiental, que poderiam contribuir para inibir os efeitos de uma cultura de consumo e de uma visão utilitarista da água, ampliando esforços individuais e coletivos para a preservação de bens comuns, como a água. Palavras-chave: psicologia ambiental; sustentabilidade; água; comportamento próambiental. x xi Abstract Although water scarcity is recognized as one of the main world-wide problems to be faced by human kind, ecologically unsustainable patterns of behavior still persist. Thus, the objective of this study was to analyze pro-environmental behavior related to water, as well as meanings associated to it by high school students of Federal Center of Technological Education of Rio Grande do Norte, in Natal. The convenience sample was composed by 315 students, 146 women and 169 men, who answered a questionnaire about use and perception of water, containing indicators of proenvironmentalism, environmental care, sustainable development, time perspective, externalities and collectivism, besides socio-demographic items. According to participants, water is synonymous of life, even though the relationship they present with it is ambiguous, much more functional than ecological; they consider it a finite resource, an indispensable life patrimony, however there was no coherence between such conceptions and the self-reported behaviors of water use. Results indicated three important predictors of pro-environmental behavior: sex of respondent, New Ecological Paradigm Scale and telephone/address left for eventual contact to participate in future environmental campaigns. They may be used in additional studies for theoretical development, or to assist in the planning of programs of environmental education, aimed at the inhibition of the effects of a culture of consumption and of an utilitarian perception of water, extending individual and collective efforts towards the preservation of common resources as water

Um lugar para chamar de "meu" :estudo sobre relação afetiva com o lugar de moradores da praia de Pipa-RN

The chores and the daily physical and social demands make us feel more and more the need to be in a familiar and restoring environment, with which we frequently establish emotional bonds. The interaction with places for resting and leisure, exemplified in the Environmental Psychology literature as recreational and home environments, allow us to exercise our potentials and to strengthen our (personal and collective) identity. Bearing this in mind, this dissertation has as aim to study the relation of affection between the place and the inhabitants of the community of Pipa-RN, which has turned from fishermen s village into tourist destination, bringing with it many changes to the local population. To accomplish that, we made use of behavioral observations, interviews, and graphic and photographic documentation with 30 subjects selected through a network of indications, attending to the criterion loving Pipa . After analysis and systematization of the answers, we identified three super-categories: 1) Love, characterized by the strong representation that an environment has upon an individual without, necessarily, there being an affective link, allowing it to be nurtured from a distance and dissociated from the desire to be present; 2) Attachment, demonstrated by the difficulty in leaving the place, a bond that can be mediated by personal financial investments or expectation of future benefits; 3) Affiliation, which refers to the feeling of belonging to the place and its community, sharing its history, culture, habits, etc., independent from the place of birth. These super-categories are not exclusive, on the contrary, they can form combinations which we denominate as situations, that could vary from 01 (individual involved with none of the three) to 07 (individual involved with the three); there wasn t the combination between Attachment and Affiliation. These results showed that within the framework of relations of affection with the place, there are countless possibilities of interaction individual-environment, determined by the physicalenvironmental characteristics and by the assessment that each individual makes of it. With this small contribution to the theme, we hope to enlighten the perspectives for future research, especially involving the relation of affection for places and the adoption of proenvironmental conducts, as a question of preservation of the ecosystems and of the quality of life of the inhabitants

Aplicação de ontologias para métodos de negociação de um sistema multiagente para o reconhecimento de padrões

The use of intelligent agents in multi-classifier systems appeared in order to making the centralized decision process of a multi-classifier system into a distributed, flexible and incremental one. Based on this, the NeurAge (Neural Agents) system (Abreu et al 2004) was proposed. This system has a superior performance to some combination-centered methods (Abreu, Canuto, and Santana 2005). The negotiation is important to the multiagent system performance, but most of negotiations are defined informaly. A way to formalize the negotiation process is using an ontology. In the context of classification tasks, the ontology provides an approach to formalize the concepts and rules that manage the relations between these concepts. This work aims at using ontologies to make a formal description of the negotiation methods of a multi-agent system for classification tasks, more specifically the NeurAge system. Through ontologies, we intend to make the NeurAge system more formal and open, allowing that new agents can be part of such system during the negotiation. In this sense, the NeurAge System will be studied on the basis of its functioning and reaching, mainly, the negotiation methods used by the same ones. After that, some negotiation ontologies found in literature will be studied, and then those that were chosen for this work will be adapted to the negotiation methods used in the NeurAge.

Um modelo conceitual baseado em MDD e padrões para evolução de sistemas OA

Aspect-Oriented Software Development (AOSD) is a technique that complements the Object- Oriented Software Development (OOSD) modularizing several concepts that OOSD approaches do not modularize appropriately. However, the current state-of-the art on AOSD suffers with software evolution, mainly because aspect definition can stop to work correctly when base elements evolve. A promising approach to deal with that problem is the definition of model-based pointcuts, where pointcuts are defined based on a conceptual model. That strategy makes pointcut less prone to software evolution than model-base elements. Based on that strategy, this work defines a conceptual model at high abstraction level where we can specify software patterns and architectures that through Model Driven Development techniques they can be instantiated and composed in architecture description language that allows aspect modeling at architecture level. Our MDD approach allows propagate concepts in architecture level to another abstraction levels (design level, for example) through MDA transformation rules. Also, this work shows a plug-in implemented to Eclipse platform called AOADLwithCM. That plug-in was created to support our development process. The AOADLwithCM plug-in was used to describe a case study based on MobileMedia System. MobileMedia case study shows step-by-step how the Conceptual Model approach could minimize Pointcut Fragile Problems, due to software evolution. MobileMedia case study was used as input to analyses evolutions on software according to software metrics proposed by KHATCHADOURIAN, GREENWOOD and RASHID. Also, we analyze how evolution in base model could affect maintenance on aspectual model with and without Conceptual Model approaches

Formal verification of PLC programs using the B Method

PLCs (acronym for Programmable Logic Controllers) perform control operations, receiving information from the environment, processing it and modifying this same environment according to the results produced. They are commonly used in industry in several applications, from mass transport to petroleum industry. As the complexity of these applications increase, and as various are safety critical, a necessity for ensuring that they are reliable arouses. Testing and simulation are the de-facto methods used in the industry to do so, but they can leave flaws undiscovered. Formal methods can provide more confidence in an application s safety, once they permit their mathematical verification. We make use of the B Method, which has been successfully applied in the formal verification of industrial systems, is supported by several tools and can handle decomposition, refinement, and verification of correctness according to the specification. The method we developed and present in this work automatically generates B models from PLC programs and verify them in terms of safety constraints, manually derived from the system requirements. The scope of our method is the PLC programming languages presented in the IEC 61131-3 standard, although we are also able to verify programs not fully compliant with the standard. Our approach aims to ease the integration of formal methods in the industry through the abbreviation of the effort to perform formal verification in PLCs

Prognostic factors for perioperative pulmonary events among patients undergoing upper abdominal surgery

CONTEXTO E OBJETIVO: Associações significativas entre cirurgia do abdome superior e eventos pulmonares do período perioperatório foram investigadas em pacientes com condições pulmonares pré-operatórias submetidos a anestesia geral. TIPO DE ESTUDO E LOCAL: Estudo retrospectivo cujos dados foram retirados de banco de dados obtidos prospectivamente de forma protocolada, de 1 de janeiro de 1999 a 31 de dezembro de 2004, em hospital universitário terciário. MÉTODOS: Estudados 3107 pacientes com mais de 11 anos, American Society of Anesthesiologists (ASA) I, II, III, com cirurgia de abdome superior sob anestesia geral, enviados à sala de recuperação. Condições pré-operatórias analisadas por regressão logística foram: idade, sexo, estado físico ASA, insuficiência cardíaca congestiva, asma, doença pulmonar obstrutiva crônica, insuficiência respiratória e hábito de fumar. Os resultados estudados, ou variáveis dependentes, incluíram eventos intra- e pós-operatórios: broncoespasmo, hipoxemia, hipercapnia, intubação prolongada e secreção de vias aéreas. RESULTADOS: Dos 3.107 pacientes: 1.540 eram homens, 1.649 mulheres, tinham média de 48 anos, 1088 ASA I, 1402 ASA II, 617 ASA III, com insuficiência cardíaca havia 80, asma, 82, doença pulmonar obstrutiva, 122, insuficiência respiratória, 21, hábito de fumar, 428. Pela regressão logística, sexo feminino (p < 0.001), idade maior que 70 anos (p < 0.01), hábito de fumar (p < 0.001) e doença pulmonar obstrutiva crônica (p < 0.02) influenciaram significativamente o desenvolvimento de eventos pulmonares, principalmente hipoxemia e broncospasmo, em ambos os períodos, mas não nos mesmos pacientes. Asma e insuficiência cardíaca não se associaram com eventos pulmonares na sala de recuperação. CONCLUSÃO: em cirurgia do abdome superior sob anestesia geral, sexo feminino, idade maior que 70 anos, hábito de fumar e doença pulmonar obstrutiva crônica foram fatores de risco independentes para a ocorrência de eventos pulmonares intra- e pós-operatórios.

Qualidade de vida e saúde física e mental de médicos: uma autoavaliação por egressos da Faculdade de Medicina de Botucatu - UNESP

OBJETIVO: O presente artigo teve como objetivo analisar resultados de autoavaliações em termos de qualidade de vida (QV), saúde física (SF) e saúde mental (SM) realizadas por ex-alunos do curso de medicina de uma universidade pública brasileira, associando-se tais indicadores a dados demográficos e diversas dimensões da atuação profissional. MÉTODOS: estudo de corte transversal que teve como população-alvo todos os egressos da Faculdade de Medicina de Botucatu (UNESP) no período de 1968 a 2005, utilizando-se um questionário autoaplicável, respondido por correio ou internet. RESULTADOS: Dos 2.864 questionários enviados, 1.224 (45%) foram respondidos. Tanto a QV como SF e SM foram avaliadas como boa ou muito boa por 67,8%, 78,8% e 84,5% dos participantes, respectivamente. Nos modelos finais de regressão logística, associaram-se a avaliação favorável de QV: ter boa SF e SM, frequentar congressos regulamente, ter tempo suficiente de lazer e estar satisfeito com a profissão. SF boa ou muito boa associou-se independentemente com QV e SM positivas, faixa de renda mais alta, prática regular de atividades físicas e nunca ter fumado. SM favorável permaneceu associada com satisfação profissional, tempo para lazer, e boa avaliação da QV e da SF. CONCLUSÕES: Entre os médicos egressos da UNESP, SF e SM foram aspectos indissociáveis e também relacionados à QV. Bons hábitos, como praticar atividades físicas, ter tempo para lazer e não fumar foram associados à melhor avaliação da saúde em geral e devem ser incentivados. A satisfação profissional teve um peso importante no bem-estar emocional relatado pelos participantes.

Diretrizes para cessação do tabagismo - 2008

Estas diretrizes constituem uma ferramenta atualizada e abrangente para auxiliar o profissional de saúde na abordagem do tabagista, recomendando atitudes baseadas em evidências clínicas como a melhor forma de conduzir cada caso. de forma reduzida e mais objetiva possível, o texto final foi agrupado em dois grandes itens: Avaliação e Tratamento. Os dois itens apresentam comentários e níveis de recomendação das referências utilizadas, bem como algumas propostas de abordagem, como por exemplo, redução de danos, em situações específicas ainda pouco exploradas, como recaídas, tabagismo passivo, tabagismo na categoria médica e uso de tabaco em ambientes específicos.

Programa de cessação de tabagismo como ferramenta para o diagnóstico precoce de doença pulmonar obstrutiva crônica

OBJETIVO: A doença pulmonar obstrutiva crônica (DPOC) é subdiagnosticada e subtratada, o que resulta em subestimação do impacto da doença. O objetivo deste estudo foi avaliar se a inclusão da espirometria na avaliação dos fumantes que ingressam em programas de cessação do tabagismo contribui para o diagnóstico precoce da DPOC. MÉTODOS: Análise retrospectiva de dados médicos de 158 fumantes atendidos no programa cessação de tabagismo (Faculdade de Medicina de Botucatu, São Paulo, Brasil), de janeiro 2003 a novembro 2005. Todos os indivíduos tinham mais de 40 anos (idade média: 55 ± 8,5 anos), sendo 99 (62,6%) do sexo feminino. Foram analisados os dados clínicos, os diagnósticos médicos prévios e os resultados da espirometria. RESULTADOS: Dos 158 fumantes avaliados, 57 (36,1%) indivíduos preenchiam os critérios diagnósticos para DPOC e 14 (8,9%) foram considerados em risco para o desenvolvimento da doença. Dos 57 que preenchiam os critérios diagnósticos para DPOC, 39 (68,4%) foram diagnósticos novos e 18 (31,6%) foram confirmação de diagnóstico prévio da doença. Entre os 18 com diagnóstico anterior, 10 (56%) tinham doença leve/moderada e 8 (44%) doença grave. Sete pacientes com diagnóstico anterior de DPOC apresentaram resultados de função de pulmonar não compatíveis com os critérios diagnósticos da doença. Entre os 39 novos diagnósticos, 38 (97,4%) eram de doença leve/moderada e apenas 1 (2,6%) tinha DPOC grave CONCLUSÃO: A inclusão da espirometria na avaliação inicial dos fumantes admitidos em programa de cessação de tabagismo pode ser uma ferramenta útil para o diagnóstico precoce da DPOC.

Perfil de fumantes atendidos em serviço público para tratamento do tabagismo

OBJETIVO: Avaliar o perfil dos fumantes que procuraram serviço público de cessação do tabagismo. MÉTODOS: Foram avaliados retrospectivamente os dados coletados durante a avaliação para a admissão no programa de cessação do tabagismo do Ambulatório de Tabagismo da Faculdade de Medicina de Botucatu/Universidade Estadual Paulista, na cidade de Botucatu (SP) entre abril de 2003 e abril de 2007. Variáveis demográficas, uso prévio de abordagem comportamental e/ou farmacológica e/ou tratamentos alternativos para o tabagismo, grau de dependência à nicotina e comorbidades foram avaliados em 387 fumantes. RESULTADOS: em nossa casuística, 63% dos tabagistas eram do sexo feminino. A idade média dos sujeitos foi de 50 ± 25 anos. Mais da metade dos fumantes (61%) não tinha cursado o ensino médio, e 66% tinham renda mensal menor que dois salários mínimos. O grau de dependência foi elevado/muito elevado em 59%, médio em 17% e baixo/muito baixo em 24%. Embora 95% dos pacientes apresentavam comorbidades, apenas 35% foram encaminhados ao programa por um médico. Mais da metade (68%) tinha feito pelo menos uma tentativa de cessação, 83% sem um programa de tratamento estruturado. CONCLUSÕES: Os tabagistas que procuraram assistência para cessar o tabagismo apresentaram desvantagem social, dependência à nicotina alta e tentativas anteriores de cessação sem tratamento estruturado. Portanto, a intervenção para o controle do tabagismo deve contemplar as características gerais dos fumantes nos serviços públicos para que seja eficaz.
