The theoretical foundation of this study addresses the construct Quality of Worklife involving pro-active reading organizations in face to social developments of the working class, which is a challenge to the people s management. In this sense, as a contribution to the studies of quality of worklife (QOWL), this study addresses the quality of lifework of nurses at Walfredo Gurgel and Santa Catarina public hospitals. The goal is to make a diagnosis about the quality of lifework of these employees taking as a basis dimensions and performance indicators shown in the model by Fernandes (1996). The research is characterized by field, in a descriptive way. This survey comprised 75 nurses, with 49 by Walfredo Gurgel hospital and 26 by Santa Catarina one. The data collection was carried out through structured questionnaire. The questions were processed in the software Statistic 6.0, with factor analysis and multiple regressions, after the systematization of data. As a result, the most nurses in hospitals are dissatisfied with the quality of lifework, with the highest incidence in Santa Catarina hospital. The variable occupational health assessment was more negative in the hospital Santa Catarina one, whereas in Walfredo Gurgel, was family assistance. The variable guarantee of employment was more positive assessment in two hospitals without, though, implying in high importance on QOWL of nurses. The factor structure and decision showed greater sensitivity to explain the QOWL of nurses, joining 17 variables from 40 of the model. The factor working conditions, joining 6 variables, showed the second highest sensitivity. The compensation factor, gathering 5 variables, showed the third highest sensitivity while image and health factors showed minor importance

New technologies appear each moment and its use can result in countless benefits for that they directly use and for all the society as well. In this direction, the State also can use the technologies of the information and communication to improve the level of rendering of services to the citizens, to give more quality of life to the society and to optimize the public expense, centering it in the main necessities. For this, it has many research on politics of Electronic Government (e-Gov) and its main effect for the citizen and the society as a whole. This research studies the concept of Electronic Government and wishes to understand the process of implementation of Free Softwares in the agencies of the Direct Administration in the Rio Grande do Norte. Moreover, it deepens the analysis to identify if its implantation results in reduction of cost for the state treasury and intends to identify the Free Software participation in the Administration and the bases of the politics of Electronic Government in this State. Through qualitative interviews with technologies coordinators and managers in 3 State Secretaries it could be raised the ways that come being trod for the Government in order to endow the State with technological capacity. It was perceived that the Rio Grande do Norte still is an immature State in relation to practical of electronic government (e-Gov) and with Free Softwares, where few agencies have factual and viable initiatives in this area. It still lacks of a strategical definition of the paper of Technology and more investments in infrastructure of staff and equipment. One also observed advances as the creation of the normative agency, the CETIC (State Advice of Technology of the Information and Communication), the Managing Plan of Technology that provide a necessary diagnosis with the situation how much Technology in the State and considered diverse goals for the area, the accomplishment of a course of after-graduation for managers of Technology and the training in BrOffice (OppenOffice) for 1120 public servers

Os lares de idosos são espaços com características específicas, onde a garantia de condições de trabalho saudáveis é fundamental para o bem-estar dos trabalhadores e dos idosos. O objectivo deste trabalho consistiu em avaliar a exposição ocupacional dos trabalhadores dos lares de idosos aos poluentes do ar interior e em verificar qual a prevalência de sintomas/doenças. A amostragem foi não probabilística quanto ao tipo e por conveniência quanto à técnica. A amostra foi constituída por 8 lares de idosos sedeados no concelho de Tondela e 155 trabalhadores. Foram administrados inquéritos aos trabalhadores e avaliada a qualidade do ar, bem como os níveis de temperatura e humidade relativa. Os dados foram tratados através do software estatístico IBM SPSS versão 21.0. A interpretação dos testes estatísticos foi realizada com base no nível de significância de p=0,05, com intervalo de confiança de 95%. Verificámos que as concentrações médias de dióxido de carbono, compostos orgânicos voláteis e partículas com diâmetro <10, registados em alguns lares de idosos ultrapassaram o limiar de protecção sendo essa concentração, em média, mais elevada nos lares localizados em zonas urbanas. Os sintomas/doenças com maior prevalência foram as dores de cabeça, crise de espirros, tonturas e alergias. Os edifícios apresentavam Síndroma do Edifício Doente (SED) e a maioria dos trabalhadores que indicaram possuir sintomas/doenças trabalhavam em lares de idosos localizados em zonas urbanas e residiam em zonas rurais. Torna-se perceptível que as instituições realizem monitorizações contínuas de QAI de modo a não exporem os trabalhadores e os idosos a situações de risco.

In the Hydrocarbon exploration activities, the great enigma is the location of the deposits. Great efforts are undertaken in an attempt to better identify them, locate them and at the same time, enhance cost-effectiveness relationship of extraction of oil. Seismic methods are the most widely used because they are indirect, i.e., probing the subsurface layers without invading them. Seismogram is the representation of the Earth s interior and its structures through a conveniently disposed arrangement of the data obtained by seismic reflection. A major problem in this representation is the intensity and variety of present noise in the seismogram, as the surface bearing noise that contaminates the relevant signals, and may mask the desired information, brought by waves scattered in deeper regions of the geological layers. It was developed a tool to suppress these noises based on wavelet transform 1D and 2D. The Java language program makes the separation of seismic images considering the directions (horizontal, vertical, mixed or local) and bands of wavelengths that form these images, using the Daubechies Wavelets, Auto-resolution and Tensor Product of wavelet bases. Besides, it was developed the option in a single image, using the tensor product of two-dimensional wavelets or one-wavelet tensor product by identities. In the latter case, we have the wavelet decomposition in a two dimensional signal in a single direction. This decomposition has allowed to lengthen a certain direction the two-dimensional Wavelets, correcting the effects of scales by applying Auto-resolutions. In other words, it has been improved the treatment of a seismic image using 1D wavelet and 2D wavelet at different stages of Auto-resolution. It was also implemented improvements in the display of images associated with breakdowns in each Auto-resolution, facilitating the choices of images with the signals of interest for image reconstruction without noise. The program was tested with real data and the results were good

Among the potentially polluting economic activities that compromise the quality of groundwater are the gas stations. The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel

A utilização generalizada do computador para a automatização das mais diversas tarefas, tem conduzido ao desenvolvimento de aplicações que possibilitam a realização de actividades que até então poderiam não só ser demoradas, como estar sujeitas a erros inerentes à actividade humana. A investigação desenvolvida no âmbito desta tese, tem como objectivo o desenvolvimento de um software e algoritmos que permitam a avaliação e classificação de queijos produzidos na região de Évora, através do processamento de imagens digitais. No decurso desta investigação, foram desenvolvidos algoritmos e metodologias que permitem a identificação dos olhos e dimensões do queijo, a presença de textura na parte exterior do queijo, assim como características relativas à cor do mesmo, permitindo que com base nestes parâmetros possa ser efectuada uma classificação e avaliação do queijo. A aplicação de software, resultou num produto de simples utilização. As fotografias devem respeitar algumas regras simples, sobre as quais se efectuará o processamento e classificação do queijo. ABSTRACT: The widespread use of computers for the automation of repetitive tasks, has resulted in developing applications that allow a range of activities, that until now could not only be time consuming and also subject to errors inherent to human activity, to be performed without or with little human intervention. The research carried out within this thesis, aims to develop a software application and algorithms that enable the assessment and classification of cheeses produced in the region of Évora, by digital images processing. Throughout this research, algorithms and methodologies have been developed that allow the identification of the cheese eyes, the dimensions of the cheese, the presence of texture on the outside of cheese, as well as an analysis of the color, so that, based on these parameters, a classification and evaluation of the cheese can be conducted. The developed software application, is product simple to use, requiring no special computer knowledge. Requires only the acquisition of the photographs following a simple set of rules, based on which it will do the processing and classification of cheese.

Objetivo: Compreender se o estado de saúde condiciona a qualidade de vida dos funcionários e identificar que variáveis influenciam a qualidade de vida dos funcionários da instituição. Métodos: Estudo descritivo-correlacional, quantitativo. Questionário sociodemográfico e versão portuguesa do MOS SF-36. Amostra funcionários docentes e não docentes que aceitaram participar no estudo. Tratamento dos dados através do Software Statistical Package for Social Sciences versão 20. Parecer positivo da Comissão de Ética, do diretor da instituição e consentimento informado dos participantes. Resultados: Diferenças estatisticamente significativas entre a qualidade de vida e o estado de saúde na Componente Física. À medida que aumentam os valores da Componente Mental, aumentam os valores da autoperceção de um estado de saúde mais elevado. Quando mais elevados os valores de cada componente, mais elevada é a autoperceção do estado de saúde dos inquiridos. Podem ter influência no estado de saúde e na qualidade de vida dos inquiridos a presença de doenças crónicas, as habilitações literárias e o estado civil. Conclusões: Realçada a importância da promoção da saúde, prevenção da doença, de forma a obter ganhos na qualidade de vida, ganhos em saúde, acrescentando não apenas mais anos à vida mas, mais vida aos anos. Isto porque os problemas de saúde estão na sua maioria relacionados com hábitos e estilos de vida nocivos para a saúde.
