Compressão de Imagens Usando a Função de Peano e a Transformada Wavelet 1D

In this work, spoke about the importance of image compression for the industry, it is known that processing and image storage is always a challenge in petrobrás to optimize the storage time and store a maximum number of images and data. We present an interactive system for processing and storing images in the wavelet domain and an interface for digital image processing. The proposal is based on the Peano function and wavelet transform in 1D. The storage system aims to optimize the computational space, both for storage and for transmission of images. Being necessary to the application of the Peano function to linearize the images and the 1D wavelet transform to decompose it. These applications allow you to extract relevant information for the storage of an image with a lower computational cost and with a very small margin of error when comparing the images, original and processed, ie, there is little loss of quality when applying the processing system presented . The results obtained from the information extracted from the images are displayed in a graphical interface. It is through the graphical user interface that the user uses the files to view and analyze the results of the programs directly on the computer screen without the worry of dealing with the source code. The graphical user interface, programs for image processing via Peano Function and Wavelet Transform 1D, were developed in Java language, allowing a direct exchange of information between them and the user

Monitoramento da morfologia costeira em setores da bacia potiguar sob influência da indústria petrolífera utilizando geodésia de alta precisão e laser escâner terrestre

The objective of this Doctoral Thesis was monitoring, in trimestral scale, the coastal morphology of the Northeastern coast sections of Rio Grande do Norte State, in Brazil, which is an area of Potiguar Basin influenced by the oil industry activities. The studied sections compose coastal areas with intense sedimentary erosion and high environmental sensitivity to the oil spill. In order to achieve the general objective of this study, the work has been systematized in four steps. The first one refers to the evaluation of the geomorphological data acquisition methodologies used on Digital Elevation Model (DEM) of sandy beaches. The data has been obtained from Soledade beach, located on the Northeastern coast of Rio Grande Norte. The second step has been centered on the increasing of the reference geodetic infrastructure to accomplish the geodetic survey of the studied area by implanting a station in Corta Cachorro Barrier Island and by conducting monitoring geodetic surveys to understand the beach system based on the Coastline (CL) and on DEM multitemporal analysis. The third phase has been related to the usage of the methodology developed by Santos; Amaro (2011) and Santos et al. (2012) for the surveying, processing, representation, integration and analysis of Coastlines from sandy coast, which have been obtained through geodetic techniques of positioning, morphological change analysis and sediment transport. The fourth stage represents the innovation of surveys in coastal environment by using the Terrestrial Laser Scanning (TLS), based on Light Detection and Ranging (LiDAR), to evaluate a highly eroded section on Soledade beach where the oil industry structures are located. The evaluation has been achieved through high-precision DEM and accuracy during the modeling of the coast morphology changes. The result analysis of the integrated study about the spatial and temporal interrelations of the intense coastal processes in areas of building cycles and destruction of beaches has allowed identifying the causes and consequences of the intense coastal erosion in exposed beach sections and in barrier islands

A experiência da pré-eclâmpsia vivenciada por gestantes e profissionais de saúde

The aim of this study is to understand the perceptions of pregnant women, mothers and health professional about preeclampsia and the relation between professional and patient. A qualitative approach was chosen, together with semi-structured interviews, participative observation and Test of Free Association of Words (TFAW). The data were collected in February and June 2007 at Maternidade-Escola Januário Cicco (MEJC), Natal, RN, Brazil with 61 pregnant women and 87 professionals, 20 of each group were interviewed. An interpretative and understanding perspective was used similar to that of Gadamer s hermeneutics and with the construction of themes and empirical categories. The pregnant women showed fear preeclampsia and its consequences, and to know very little about the subject and also a desire to know more. The changes that occurred with the illness were more related to the emotional order than to the healthy lifestyle they have adopted. Some lack of preparation of the basic units was observed, in order to meet and guide the pregnant women to the reference unit. Professionals knew the customers characteristics, about their fear and about their little knowledge on this illness. Nevertheless, they did not include them in the treatment. It was observed the absence of conversation over the illness between professionals and patients and also the inability of the former to deal with emotional issues. A new way of looking into the preeclampsia assistance is necessary. A way that focuses on the collective construction of intervention and approach strategies; one which includes subjective aspects in an hermeneutic perspective of health

Morte como desafio afetivo para o profissional da saúde: ansiedade e sentimentos de quem lida com o paciente terminal com câncer

It is a Cross-sectional and multi-disciplinary study whose population selection was made by department of human resources (composed by a Manager, an Oncologist and a Psychologist) from the hospital where this research was realized. They also collaborated with important information about the work of that professionals in the hospital. We also counted on a Statistic who made study design calculating the sample and analyzing data. This research issued Evaluating health professionals anxiety levels who care for cancer terminally ill and their feelings about that work as well as identifying the factors which have influence on it. 100 health professionals from the Hospital which is a reference on cancer caring in Brazil situated in the city of Natal, state of Rio Grande do Norte, participated of this research. There was a sample loss of 21%. Data were collected through a questionnaire and State-Trait Anxiety Inventory (STAI). Results showed that 15% of the professionals have low State Anxiety levels, 70% Medium State Anxiety levels and 15% high State anxiety levels. The Number of Patients and Working in another Institution have interfered in the anxiety levels. Doctors and Nursing Assistants and Technicians have got the highest high State Anxiety percentage (25%). 73% of them declare to feel some sort of different behavior and/or feelings in caring for terminally ill. The most remarkable professionals feelings were Suffering and Sadness, and Terminally ill Children was the most difficult age group to care for. We conclude that work overload and having more than one job can interfere in professional stress levels and anxiety. Dealing with terminally ill, specially children one, can cause on the professionals psychological suffering. It s recommended the development of supporting and training strategies to reduce and/or to prevent Stress and Anxiety high levels

Aspectos socioeconômicos e demográficos relacionados ao estresse e a síndrome de Burnout em fisioterapeutas no Brasil

Dos problemas de saúde existentes no ambiente de trabalho, 18% afetam o aparelho psíquico, a exemplo do estresse, atingindo cerca de 30% dos trabalhadores em geral. A persistência e intensidade do estresse, associada às sucessivas tentativas de lidar com os mesmos, tornam os indivíduos vulneráveis ao surgimento da Síndrome deBurnout. O objetivo deste trabalho foi identificar a relação dos aspectos socioeconômicos e demográficos com o estresse e a Síndrome de Burnout em fisioterapeutas do Brasil. Para isso, este estudo teve uma abordagem do tipo transversal, com 1040 fisioterapeutas do Brasil, através de uma amostragem do tipo snowbolle não probabilística. Utilizou-se um questionário socioeconômico, demográfico e profissional, a Escala de Estresse no Trabalho (EET) e a adaptação do Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT). Na análise dos dados, foram utilizadas a estatística descritiva e inferencial. Dentre os principais resultados obtidos, percebeu-se uma maior representatividade da região Nordeste (48,7%), com idade média de 31anos, sexo feminino (75,7%), carga horária semanal de 35,4 horas, com 3-5 anos de atuação profissional. Observou-se que 37,0% apresentavam estresse relacionado estatisticamente com a idade (p=0,008),atividade física (p=0,039) e satisfação com a saúde (r=-0,322; p<0,001). Não foi observado nenhum caso de Burnout, porém houve uma média elevada nas dimensões, desgaste psíquico, indolência e culpa, totalizando 49,0% comtendência ao desenvolvimento da síndrome. Portanto, as variáveis, idade, prática da atividade física e satisfação com a saúde obtiveramrelação com o estresse. Para o Burnout, destacaram-se a região de moradia (centro-oeste), satisfação com a saúde, local de trabalho (clínicas e hospitais), além do maior número de locais de trabalho. Diante desse contexto, os estudos sobre o estresse e a Síndrome de Burnout se apresentam como elementos derelevância dentro do contexto da prevenção dos riscos laborais e da análise das condições de trabalho

ANÁLISE COMPARATIVA DO CONHECIMENTO, ATITUDES E PRECONCEITOS DE UNIVERSITÁRIOS DOS CURSOS DE PEDAGOGIA, EDUCAÇÃO FÍSICA E MEDICINA EM RELAÇÃO À EPILEPSIA

Epilepsy is a chronic disorder of the central nervous system, most frequently characterized by abnormal electrical impulses in the brain. It is the oldest recorded neurological disease and has been surrounded by myths, mistaken beliefs and preconceptions. Three professionals work with epileptic patients on a daily basis: teachers, physical educators and physicians . This study aimed to analyze and compare the level of knowledge, preconceptions and attitudes of undergraduate students in the courses of Pedagogy, Physical Education and Medicine, future professionals who will deal with epileptic patients. This descriptive observational study was conducted with 286 university undergraduates of both sexes (women 99/34.6% and men 187/65.4%) from the first to fourth year of Pedagogy, Physical Education and Medicine courses at the Universidade Estadual Rio Grande do Norte (UERN), with mean age of 23 years. A validated and adapted 17-question questionnaire, divided into nine knowledge-based questions, five related to preconceptions and three on attitudes, was applied. Results allowed elaboration of a manuscript entitled Comparative Analysis of Knowledge, Attitude and Preconceptions in University Undergraduates of Pedagogy, Physical Education and Medicine Courses in Relation to Epilepsy. The findings of this article show that knowledge of epilepsy in the three groups is very satisfactory. The low level of preconception indicates that educational or clarifying information is being transmitted, albeit by television, a layman s information vehicle, which has undoubtedly contributed to reducing the stigma of epilepsy through educational information. Results also suggest a lack of knowledge on how to act during a seizure, especially in education professionals. Although there are limitations in our sample, the relevance and contribution of this study is to call attention to the importance and need for these future professionals to be informed and learn correct attitudes with respect to epilepsy during their academic formation. This is essential at a time when the disease is being brought out of the shadows. This research was supported by the Office of the Dean of Teaching, and Deans of Pedagogy, Physical Education and Medicine at UERN. The research was made possible by the multidisciplinary interaction among a physical educator, child neurologist and statistician, all contributing to achieving the aims set out here

A encruzilhada da vida política em assentamentos de reforma agrária no Rio Grande do Norte

The rural settlements represent a mark in the expensive historical process of fight by the land in Brazil. At first offer basic terms of survival, through the access the land and of the fundamental supports for exploration. At the same time, have stimulated organization forms politicizes of the families who manage to work with the new challenges of the everyday. The moment that follows the land conquest, and therefore, the settlements construction while life and work project, it is crossed for objective and subjective demands, with highlight for options of agricultural production and strategies of collective action. Originally formed as representation instance legitimates of the families - front to the government and social actors - the settlers associations are private spaces for political sociability, that guided by principles participative, can lead the settlers the new conquests through indeed democratic experiences. The goal of this work is to comprehend the participation forms in the scope of these associations and the way as that translates in life best terms for the group, from the settlements experiences located in the Territories of the Citizenship Mato Grande and Açu-Mossoró, in Rio Grande do Norte's State. The theoretical conceptions that guide this analysis are concentrate on discussions about democracy and participation (Patermam, Putnam, Bodernave) and in the reflections about the rural world (Medeiros, Martins, Woodman e Woodman and Bergamansco). About methodological, different point of view strategies were developed: The direct observation, the application in locate of questionnaires to the families settlers and interviews semi-structured with the internal leaderships. With that could verify that the participation forms in the associations operate in two heartfelt: Of a side, they promote assimilation opportunities of democratic abilities accompanied of notions of social rights and redefinition of political standards; Of another, it offers indeed the possibility of the settlers lead, with relative autonomy, the political organization and her changes in direction to a way of life that wish to have in the settling

Reestruturação produtiva na Petrobrás e ação sindical dos petroleiros do RN

Ce travail a l objectif d analyser la question de la restructuration productive dans la Petrobrás/ RN et les implications possibles sur l action syndicale du Sindipetro/RN pendant la période 1995 2003. La restructuration productive dans la Petrobrás/RN commence dans la décennie 1990 quand l entreprise, au niveau national, décide d adhérer au Programa Brasileiro de Qualidade e Produtividade PBQP lancé par le gouvernement Collor comme motivation et priorité pour que les entreprises s adaptent à l ouverture de l économie brésilienne au marché extérieur. De ce fait, la Petrobrás/RN afin de se maintenir dans le marché compétitif et mondialisé , adopte des techniques administratives basées sur la philosophie de la qualité totate, met au point des inovations technologiques et organisationnelles, tout en altérant sa base technique et adopte, encore, la tertiairisation de quelques activités visant à la reduction des coûts. De telles mesures ont atteint de façon remarquable l action du Sindipetro/RN qui commence alors à agir selon la logique de la politique néo-libérale du gouvernement de conduite anti-syndicale. Face à ces faits le syndicat a rédéfini ses actions dans le but de trouver des manières de poursuivre les luttes syndicales dans cette conjoncture de difficultés dans les relations de travail. Celui-ci s engage donc à entamer les négociations comme stratégie afin de préserver les privilèges de la catégorie et d éviter la perte des droits acquis

Desejo, preconceito e morte: assassinatos de LGBT em Segipe 1980 a 2010

This study examines the phenomenon of the murders of LGBT in Sergipe, between 1980 and 2010. Data were collected from newspapers, police, and judicial proceedings in the Courts with family members and friends of victims. The data show that despite the existence of death for involvement with drugs (crack), crimes of passion, among others, homophobia is one of its most characteristic elements. The victim profile also differs greatly from the aggressor, while the first is made up of individuals aged 25 to 44 years, the offender is between 15 and 29 years. Added to this the sensationalism of the press, the limits of police and justice in dealing with such events. The results seem to be forgetting some of the cases that do not reach the jury. It is an extensive study that combines statistical and qualitative data with a view to offering a closer look at the issue. The result is a mapping of brutal crimes, which, in part, has homophobia as the primary cause for its implementation

OBALUAIÊ: um estudo sobre o estigma no convívio com o HIV/Aids em terreiros de Umbanda na cidade de Fortaleza-Ceará

The tradition and living in African-Brazilian religious spaces, called yards, reveal how dynamic the reproduction and exchange of knowledge are, and that through their worldview, reveal ways of dealing with health and disease. The yards are culturally rich territories, in which people shape concepts, practices, and beliefs about health, disease and forms of healing, passed on from generation to generation through oral tradition. With the advent of HIV/AIDS from the 80s, a new challenge is established in the community of the yards and in the individual trajectories of people affected by the disease, who since an early age participate in this religious practice. The objective of this research is the analysis on the stigma in living with HIV/AIDS in yards of Umbanda in Fortaleza-Ceará, considering the (re)production of social dramas experienced by the community in question. During the investigation we adopted two basic parameters: the first one considers the understanding of the reproduction of stigma (or deteriorated identity) in relation to HIV/AIDS in its socio-historical dimension and its effects in the investigated context (Goffman, 1988). And the second one refers to the creation and reproduction of social dramas as a social experience carried through learning, handling and symbolic performance, which is reproduced in four stages: rupture, crisis, corrective action and reintegration (Turner, 1971)

A Eficácia dos direitos fundamentais nos contratos civis e de consumo: uma teoria contratual baseada na colisão dos direitos ou bens constitucionalmente protegidos

The apparent virtuosity that if could wait of the globalization and the neoliberalism has given signals of deterioration in the contractual relations, especially in contracts of mass consumption, generating innumerable offensive situations to the basic rights and the goods constitutionally protected of the contractors. In the world of today, still that it does not reveal any desire, the individual practically is compelled to contract, for force of necessities and customs completely imposed, mainly in face of the essentiality of the services or agreed to goods. Ahead of as much and unexpected changes in the civil liames and of consumption, dictated for the globalization, it comes to surface the reflection if the private law e, more specifically, the civil law, meet prepared adequately to deal with these new parameters of the economy. The present dissertation has the intention to investigate if the globalization and the consequent neoliberalism, in this beginning of third millennium, will imply to revive of the principles and the basics paradigms of the contracts that consolidated and had kept, for more than two centuries, the liberal State. One notices that the study of this phenomenon it gains importance to the measure where if it aggravates the decline of the social State (Welfare State), with the embrittlement and the loss of the autonomy of the state authority, over all in countries of delayed modernity, as it is the case of Brazil, that presents deep deficiencies to give or to promote, with a minimum of quality and efficiency, essential considered public services to the collective and that if they find consecrated in the Federal Constitution, as basic rights or as goods constitutionally protecting, the example of the health, the education, the housing, the security, the providence, the insurance, the protection the maternity, the infancy and of aged and deficient. To the end, the incidence of constant basic rights of the man in the Constitution is concluded that, in the process of interpretation of the right contractual conflicts that have as object rights or goods constitutionally proteges, in the universe of the globalized perhaps economy and of the neoliberalismo, it consists in one of the few ways - unless the only one - that still they remain to over all deal with more adequately the contractual relations, exactly that if considers the presence of clauses generalities in the scope of the legislation infraconstitutional civil and of consumption, front the private detainers of social-economic power. To be able that it matters necessarily in disequilibrium between the parts, whose realignment depends on the effect and the graduation that if it intends to confer to the basic right in game in the private relation. The Constitution, when allowing the entailing of the basic rights in the privates relations, would be assuming contours of a statute basic of all the collective, giving protection to the man against the power, if public or independently private

Desenvolvimento como acesso às políticas públicas: a reforma do estado e a concretização dos direitos prestacionais

The state s evolution, after its liberal and the social stages, arrives at the post-social state, also regarded as regulatory state, which, in order to accomplish the state s aims, employs indirect interventions in the economy. The new model of administration adapts principles and concepts form the private sector such as the quest for efficience and tangible results, also striving for the decentralization of state s power to improve effectiveness before the new paradigm of handling of affairs of public interest. Present state derives its legitimacy from the efficiency principle, the legitimacy of the public administration cannot be limited to an analysis of legality, but the fulfillment of the ends envisaged by the public authority on its policies. These public policies have the objective of satisfying fundamental rights of the citizens. The access to public policies set by states as a way of enjoyment of the aforementioned rights constitute a legal and demandable path of development. The creation of public policies and the access to them must abide to the efficiency principle. This access must be taken unther the principles of legal and material equality, inasmuch as the liberty and real liberty. The access must also be observed as a matter of limited resources to grant, in reality, the access and enjoyment of these rights. The demandable nature of the access to public policies binds the public authority into broadening the range of these policies to every one who needs them. Thus, in this spectrum, the role of the Regulatory State, as the legal instruments for access of public policies as a legal path to development, is analyzed in the present work
