This work presents a boundary element formulation for the analysis of building floor slabs, without beams, in which columns are coupled with the plate. An alternative formulation of boundary element method is presented, which considers three nodal displacements values (w, partial derivativew/partial derivativen and partial derivativew/partial derivatives) for the nodes at the boundary of the plate. In this formulation three boundary equations are written for all nodes at the boundary and in the domain of the plate. As the nodes of the column-plate connections are also represented by three nodal values, all these structural elements can be easily coupled. It is supposed that the cross-sections of the columns remain flat after the deflection and consequently the assumption of linear variation of the stress in the plate-column contact surface is also valid.

This work presents an application for the plate analysis formulation by BEM where 3 boundary equations are used, written for the transverse displacement w and the normal and tangential derivatives partial derivativew/partial derivativen and partial derivativew/partial derivatives. In this extension, the transverse displacement w is approximated by a cubic polynomial and, as a consequence, partial derivativew/partial derivatives has a quadratic approximation. This alternative BEM formulation improves the analysis of thin plates, when compared to the formulation using the linear approximation for the displacements, mainly in the obtaining of the bending moments at the boundary of the plate. The implementation of this proposal to the computational codes is simple. (C) 2004 Published by Elsevier Ltd.

Are there values that predict health? Moreover, would the absence of health motivate deterioration in the subjective well-being? This research has attempted to find answers to these questions by verifying in which proportion human values explain the subjective well-being experienced by people in different contexts of value reference. Both musicians and lawyers have been studied. In a preliminary study, composed of two researches, it was attempted to overcome the lack of bibliography in order to make known the current context of these professions in João Pessoa, Paraíba, through newspaper articles from the Correio da Paraíba and interviews with privileged informers. The technique of content analysis was then used identifying the main dilemmas of the professions as well as their socio-occupational contexts. In the second and main study, the aim was to verify the existing relations among the variables of subjective well-being and the human values for these professionals adopting the socioeconomical panorama of the occupations to support the analysis. 387 professionals took part in this study: 148 musicians (31.8% instrumentalists) and 239 lawyers (36.8% civil), with ages varying from 18 up to 77 years old (M=35.9; SD=12.35), and from 22 up to 79 years (M =38.6; SD=12.31), respectively, answered the Basic Human Values (BHV); Positive and Negative Affect Scale; Vitality Scale; General Health Questionnaire GHQ-12; Satisfaction with Life Scale and the socio-demographic questions. The SPSS Statistical Package for the Social Sciences was used and it could be observed that, for the musicians, the importance of the type of existence/bio-social value stands out just as an indicator of vitality. The type of value Accomplishment/Power, showed itself important for the positive affection and for vitality, while the types Accomplishment/Self-direction and Normative haven t had any influence in the subjective well-being. Only the relation between the Existence/Bio- Social type and vitality was mediated by the sex and marital status variables. As for the lawyers, the type of predictor value of the subjective well-being was the normative [F(1,219) = 11,8, p ≤ 0,001; Rmultiple = 0,23, R2adjusted = 0,05]. On the other hand, the type Existence/Bio social presented a direct relation with vitality but inverse with depression. It was then concluded that the congruency of personal values with those promoted in the social context of reference may be an indicator of subjective well-being, given the existence of a social value context well demarcated

The elaboration of this thesis aimed at getting to know the structure of the psychological well-being (PWB) at work and analysing the differences in the PWB levels among technical-administrative servants in public and private Institutions of Higher Education (IES) in the municipality of João Pessoa. Two hundred and thirty-three public and private IES male and female servants of João Pessoa participated in the research, replying to an instrument composed of questionnaires referring to the elaborated model. Factorial and regression analyses were accomplished in order to test the hypotheses in respect of the proposed model. The results showed that the PWB related with the work is composed of indicators such as affection, vitality, anxiety, depression, satisfaction at work and aspiration for accomplishment and reduction of the self-efficiency. The observed PWB predictors at work were the IES type, presence of children, age and the escape and back-out facing strategy. These predictors possess relationship of moderation among them in the explanation of PWB. On comparing the PWB experienced by the technical-administrative servants, it was observed that those linked to private IES showed higher PWB rates. Furthermore, there are differences among PWB predictors in accordance with the IES type. The applicability of the results of this thesis is wide as regards social interventions in the search of health improvement under a psycho-sociological perspective. Eventually, the thematic of this thesis intends to reinforce the studies on the worker s health, since by knowing what would lead him into a feeling of accomplishment and well-being will result in more chances of promoting him, while creating opportunities of a sounder life for these people in psychological terms

The intensification of the fear in the city and in the spaces controlled by this feeling has contributed to a growing socio-spatial inequality, and the rapid growth of market protection. The residential condos emerge as a possible solution to the problem. This is a housing typology expanding worldwide which is seen, especially by the urban middle class, as enablers of quality of life and safety. In Brazil, especially in large cities, the quest for quality of life is directly connected with the desire for security translated through space control (use of high walls, gates, entrance hall, security cameras) and people who use it. This thesis aims at investigating how the different categories of inhabitants of an area predominantly occupied by vertical residential condos realize the socio-spatial dimension and the socio-urban space determined by this type of development. It especially takes into consideration the issue of urban insecurity, based on the assumption that, although published and sold by marketing as safe places , synonym of welfare and supporters of community life , the living in these condos, may even inhibits, social relationships, contributing to socio-spatial isolation and consequent social weakness. This is a survey that seeks to meet the assumptions of Environmental Psychology towards the comprehension of person-environment studies, emphasizing the use of different methods (desk research, observations of and group interviews, focus group technique using photographic resources), as well as the focus on current problems of the urban scene and the knowledge gained in Social Psychology

In this work, are discussed two formulations of the boundary element method - BEM to perform linear bending analysis of plates reinforced by beams. Both formulations are based on the Kirchhoffs hypothesis and they are obtained from the reciprocity theorem applied to zoned plates, where each sub-region defines a beam or a stab. In the first model the problem values are defined along the interfaces and the external boundary. Then, in order to reduce the number of degrees of freedom kinematics hypothesis are assumed along the beam cross section, leading to a second formulation where the collocation points are defined along the beam skeleton, instead of being placed on interfaces. on these formulations no approximation of the generalized forces along the interface is required. Moreover, compatibility and equilibrium conditions along the interface are automatically imposed by the integral equation. Thus, these formulations require less approximation and the total number of the degrees of freedom is reduced. In the numerical examples are discussed the differences between these two BEM formulations, comparing as well the results to a well-known finite element code.

In this work, the plate bending formulation of the boundary element method - BEM, based on the Reissner's hypothesis, is extended to the analysis of plates reinforced by beams taking into account the membrane effects. The formulation is derived by assuming a zoned body where each sub-region defines a beam or a slab and all of them are represented by a chosen reference surface. Equilibrium and compatibility conditions are automatically imposed by the integral equations, which treat this composed structure as a single body. In order to reduce the number of degrees of freedom, the problem values defined on the interfaces are written in terms of their values on the beam axis. Initially are derived separated equations for the bending and stretching problems, but in the final system of equations the two problems are coupled and can not be treated separately. Finally are presented some numerical examples whose analytical results are known to show the accuracy of the proposed model.

In this work, a boundary element formulation to analyse plates reinforced by rectangular beams, with columns defined in the domain is proposed. The model is based on Kirchhoff hypothesis and the beams are not required to be displayed over the plate surface, therefore eccentricity effects are taken into account. The presented boundary element method formulation is derived by applying the reciprocity theorem to zoned plates, where beams are treated as thin sub-regions with larger rigidities. The integral representations derived for this complex structural element consider the bending and stretching effects of both structural elements working together. The standard equilibrium and compatibility conditions along interface are naturally imposed, being the bending tractions eliminated along interfaces. The in-plane tractions and the bending and in-plane displacements are approximated along the beam width, reducing the number of degrees of freedom. The columns are introduced into the formulation by considering domain points where tractions can be prescribed. Some examples are then shown to illustrate the accuracy of the formulation, comparing the obtained results with other numerical solutions.

Wich the big transformations at the world of labor, thus as the appearing of the negatives psicologicals consequencies? Publications in books and articles about the health of the workers have been seen in the last 40 years, pointing at the increase of occupational ills, increase of the absenteeism, reach the redation between the labor and the family. With the appearing of the neoliberal sistem, changed all the net of relations, thus as the temporary labor contract, the flexibility at the work timetable, and others, that privilege the capitalism, in detriment of the worker health. It was given emphasis to the banking worker, in time that the banks and the banking agencies were one of the departaments that more suffered the impact of the productive restructuring at the last years. 200 bank clerks shared the search, in that 41,9% was female and 58,1% was male, 60,9% presenting a civil state married, following of 28,4% of single. The participants answered the following instruments: Scale of Positives and Negative Kindness, General Health Questionaire GHQ 12, Scale of Organization, Conditions and Labor Relations, Scale of Desire (own authorship), Scale about economic situation and a social-demographic record car. With the objective of trying the instruments of measure, it was checking the psychometric parameter of the search scales. We could verify that it has been more positive than negative ones for the mental health, but it was found some kind of depression and unsatisfied with their lives in some pieces of the sample. We can finally say that the work place has an impact at the mental health of the bank clerks. So, some interventions actions to promote the worker health could be essential

The subjective well- being (SWB) is formed by global judgments of satisfaction with life, or with peculiar domains the positive and the negative emotional experiences. The perception in turn, is the process of interpretive process of sensory data with cognitive or informative sense, absorbed in function of a context. From this perspective, the research aimed to evaluate SWB and the perception of advanced age pregnant women. Participated in the survey 80 pregnant with 35 years old or older (Group A or older) and 80 pregnant aged between 20 and 34 years old (Group B or young adults). The instruments used were: the scale of subjective well-being and a questionnaire, that included sociodemographic informations, items about pregnancy and a statement based on the Free Association of Words Technique (FAWT) to approach the perception of pregnancy. The data from the questionnaire and scale, in order to compare the data between groups suffered descriptive and inferential statistical analyzes. The analyzes performed with chi-square test among groups, which had values that were statistically significant, with the sociodemographic variables the type of contraceptive and health problems. The indicators of the SWB had further more by means in groups. The results of the Wilcoxon's test that there were no differences between the groups referred above. In the relation indicators of well being with variables age, education and income, some associations were significant. In addition, the words derived from the (FAWT) were analyzed using the software Programmer s Permenttant l´Analyse des Evocation (EVOC2000) and categorized according to content analysis of Bardin in three thematic categories (positive and negative affects, perception of gestation and implications of pregnancy) discussed as a group, since most of words were common. The study highlights shown how similar were the presented data by pregnant women surveyed. It is supposed about this fact the similarity is related to the social context. The relevance of this study for the health care network is to help with proposals aimed at specific improvements to the public and the sector, beside demonstrate that advanced age pregnant women and young adulst in the researched context showed no differences in the most of the studied characteristics

The elderly population growth in Brazil and in the world is an incontestable reality, arising from a significant declining rate in mortality and fertility, resulting from the remarkable improvements in the quality of life of the people. Associated with the introduction of new technologies in the medical area, these issues have been highly contributing for the increase of the population longevity. The numbers of the elderly in Brazil and in the world show female population predominance within the aging segment, a phenomenon known as the feminisation of the old-age . Aging, therefore, is nowadays one of the primary issues and that has been mobilizing the Brazilian s society, since the development raised from this new reality brought with it enormous challenges and complex social implications which are already felt in the daily lives of the societies. My work experience among some age groups has shown that aging is a much differentiated process which has instigated my interest in understanding why aging has to face an overwhelming and painful experience for some people and enriched and full of signification for others. Overviewing, this research aimed to understand the aging development through the analysis of the processes of signification and production of meaning that permeate the aging and the subjective well-being of three aged women participants of the Project Health and Citizenship on Third Age /CEFET-RN, that evidenced attitudes and behaviors concerning the integration and the activity toward the elderly population. The methodological strategy used was History of Life, starting from collecting data based on deep interviews. The analysis of data evidenced that the elderly well-being is a unique and distinct meaningful experience for each person, concerning each story of their lives within differentiated social, cultural, economic context, from this perspective one can demystify the concept of that aging occurs in a homogeneous way for everyone, everywhere and with the same rhythm. The narratives presented in this research showed the human development as being a dialectic, discursive and interactionist process which extends throughout the adult life and continues to the aging life. The guarantee that development and aging are a parallel phenomenon always in interdependence on the preceding phases of live, are corroborated within the studies. This present study confirms that the elderly population can be a phase of growth, personal realization and continued development, without disrespecting the heterogeneous and the subjectivity of the person who ages. Notifying those healthy and well-succeeded aging experiences, this issue has the intention to contribute to demystify the concept of aging as a social problem, illness needed to be treated, and the stereotypy of the elderly being dependent and unproductive

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups

The present study aimed to understand patients' experience with osteoporosis treatment. The methodological and theoretical frameworks were, respectively, the Grounded Theory and Symbolic Interactionism. The research subjects were 12 patients monitored in a specialized outpatient unit. The obtained statements were transcribed and analyzed, leading to a synthesis of the described themes. From the analysis process, two phenomena emerged: "self-evaluating health conditions according to the disease signs" and "making a decision about the treatment targeting at well-being". The realignment and the inter-relationship of the components belonging to these phenomena (themes, categories, and subcategories) allowed to identify the core category: "self-managing osteoporosis treatment for well-being recovery mediated by the (in)visibility of the disease signs". Furthermore, it allowed for the design of a theoretical model concerning the process used by the player in his cyclic movement of the experience, between adherence to and relaxation from the osteoporosis treatment.

The gravity inversion method is a mathematic process that can be used to estimate the basement relief of a sedimentary basin. However, the inverse problem in potential-field methods has neither a unique nor a stable solution, so additional information (other than gravity measurements) must be supplied by the interpreter to transform this problem into a well-posed one. This dissertation presents the application of a gravity inversion method to estimate the basement relief of the onshore Potiguar Basin. The density contrast between sediments and basament is assumed to be known and constant. The proposed methodology consists of discretizing the sedimentary layer into a grid of rectangular juxtaposed prisms whose thicknesses correspond to the depth to basement which is the parameter to be estimated. To stabilize the inversion I introduce constraints in accordance with the known geologic information. The method minimizes an objective function of the model that requires not only the model to be smooth and close to the seismic-derived model, which is used as a reference model, but also to honor well-log constraints. The latter are introduced through the use of logarithmic barrier terms in the objective function. The inversion process was applied in order to simulate different phases during the exploration development of a basin. The methodology consisted in applying the gravity inversion in distinct scenarios: the first one used only gravity data and a plain reference model; the second scenario was divided in two cases, we incorporated either borehole logs information or seismic model into the process. Finally I incorporated the basement depth generated by seismic interpretation into the inversion as a reference model and imposed depth constraint from boreholes using the primal logarithmic barrier method. As a result, the estimation of the basement relief in every scenario has satisfactorily reproduced the basin framework, and the incorporation of the constraints led to improve depth basement definition. The joint use of surface gravity data, seismic imaging and borehole logging information makes the process more robust and allows an improvement in the estimate, providing a result closer to the actual basement relief. In addition, I would like to remark that the result obtained in the first scenario already has provided a very coherent basement relief when compared to the known basin framework. This is significant information, when comparing the differences in the costs and environment impact related to gravimetric and seismic surveys and also the well drillings
