Auto-avaliação de saúde entre trabalhadores de uma indústria no sul do Brasil

OBJECTIVE: To analyze the prevalence of negative self-rated health and its factors associates among industrial workers. METHODS: Cross-sectional study with a probabilistic sample of 482 metal mechanic industrial workers of a city in Southern Brazil. Data was collected by means of self-administered questionnaire and anthropometric measures. The magnitude of the association between self-rated health and the study variables was estimated by odds ratio with 95% confidence intervals (95% CI). Multivariate logistic regression models were obtained using a theoretical hierarchical model. RESULTS: Response rate was 98.6%. Negative self-rated health was seen in 16.6% of the employees and most (84.8%) were males engaged in predominantly production activities (79.4%). The most common complaint was back pain (30.9%). After statistical modeling the following variables remained associated with negative self-rated health: females (OR=3.0 95% CI 1.5;6.2), physical inactivity (OR=1.8 95% CI 1.0;3.4), psychological stress (OR=3.0 95% CI 1.6;5.6), lack of control over life (OR=3.0 95% CI 1.5;6.1), reporting of one (OR=3.2 95% CI 1.4;7.2) or two or more chronic conditions (OR=7.7 95% CI 3.4;17.8), short-term medical leave (OR=2.9 95% CI 1.5;5.5), and incapacitating illness (OR=2.8 95% CI 1.2;6.6). CONCLUSIONS: The prevalence of negative self-rated health was associated with socioeconomic/demographic, lifestyle, psychosocial and health-related dimensions. The variable causing the greatest impact on the outcome was reporting of more than two chronic conditions.OBJETIVO: Analisar a prevalência de auto-avaliação de saúde negativa e seus fatores associados, entre trabalhadores industriais. MÉTODOS: Estudo transversal com amostra probabilística de 482 trabalhadores de indústria metal-mecânica de Joinville, estado de Santa Catarina, em 2005. As informações foram obtidas por meio de questionário auto-administrado e medidas antropométricas. Para estimar a magnitude de associação entre a auto-avaliação e variáveis, foram calculadas as razões de chances (RC) com intervalos de confiança de 95%. Foram obtidos modelos logísticos múltiplos por meio de análise de regressão logística utilizando um referencial teórico hierárquico. RESULTADOS: A taxa de resposta foi de 98,6%. A auto-avaliação de saúde negativa foi referida por 16,6% dos trabalhadores. A maioria era do sexo masculino (84,8%) e desenvolvia atividades predominantemente ligadas ao setor produtivo (79,4%). A queixa mais comum entre os trabalhadores foi dor nas costas (30,9%). Após modelagem estatística, as seguintes variáveis permaneceram associadas à auto-avaliação negativa de saúde: sexo feminino (RC=3,0; IC 95%: 1,5;6,2), inatividade física (RC=1,8; IC 95%: 1,0;3,4), tensão psicológica (RC=3,0; IC 95%: 1,6;5,6), falta de controle sobre a vida (RC=3,0; IC 95%: 1,5;6,1), referência a uma (RC=3,2; IC 95%: 1,4;7,2) ou duas ou mais doenças crônicas (RC=7,7; IC 95%: 3,4;17,8), licença de saúde de curta duração (RC=2,9; IC 95%: 1,5;5,5) e doença limitante (RC=2,8; IC 95%: 1,2;6,6). CONCLUSÕES: A prevalência de auto-avaliação de saúde negativa esteve associada às dimensões socioeconômica/demográfica, estilo de vida, psicossocial e situação de saúde. A variável que mais influenciou na auto-avaliação negativa foi a referência a mais de duas doenças crônicas

Description of surfaces associated with CPN−1CP^{N-1} sigma models on Minkowski space

The objective of this paper is to construct and investigate smooth orientable surfaces in $R^{N^2-1}$ by analytical methods. The structural equations of surfaces in connection with $CP^{N-1}$ sigma models on Minkowski space are studied in detail. This is carried out using moving frames adapted to surfaces immersed in the $su(N)$ algebra. The first and second fundamental forms of this surface as well as the relations between them as expressed in the Gauss-Weingarten and Gauss-Codazzi-Ricci equations are found. The Gaussian curvature, the mean curvature vector and the Willmore functional expressed in terms of a solution of $CP^{N-1}$ sigma model are obtained. An example of a surface associated with the $CP^1$ model is included as an illustration of the theoretical results.Comment: 19 pages, 1 figure; shorter version, some typos and minor mistakes correcte

A rigorous real time Feynman Path Integral and Propagator

We will derive a rigorous real time propagator for the Non-relativistic Quantum Mechanic $L^2$ transition probability amplitude and for the Non-relativistic wave function. The propagator will be explicitly given in terms of the time evolution operator. The derivation will be for all self-adjoint nonvector potential Hamiltonians. For systems with potential that carries at most a finite number of singularity and discontinuities, we will show that our propagator can be written in the form of a rigorous real time, time sliced Feynman path integral via improper Riemann integrals. We will also derive the Feynman path integral in Nonstandard Analysis Formulation. Finally, we will compute the propagator for the harmonic oscillator using the Nonstandard Analysis Feynman path integral formuluation; we will compute the propagator without using any knowledge of classical properties of the harmonic oscillator

Rigorous Real-Time Feynman Path Integral for Vector Potentials

we will show the existence and uniqueness of a real-time, time-sliced Feynman path integral for quantum systems with vector potential. Our formulation of the path integral will be derived on the $L^2$ transition probability amplitude via improper Riemann integrals. Our formulation will hold for vector potential Hamiltonian for which its potential and vector potential each carries at most a finite number of singularities and discontinuities

Psychosocial aspects of adolescents from public schools in Florianópolis/SC

A adolescência constitui uma etapa crítica no desenvolvimento de cada indivíduo, caracterizada por um período de riscos, problemas e conflitos. Por ser esta fase um período onde o indivíduo passa a tomar maior número de decisões e escolher por si próprio dentre as alternativas que a vida lhe oferece e dado que muitos padrões de comportamento adquiridos na adolescência e problemas de saúde contraídos durante esta fase poderão permanecer para toda a vida, é imprescindível conhecer os hábitos de saúde dos adolescentes e suas insatisfações como forma de prever e evitar um futuro indesejado. O presente estudo investigou, através da aplicação de dois questionários, enviados a estudantes e seus pais, aspectos psicossociais de 720 adolescentes (252 rapazes e 468 moças) de 16 e 17 anos de escolas públicas de Florianópolis/SC. Diferenças entre grupos, avaliadas através do teste do qui-quadrado de Pearson, revelaram que as moças apresentaram mais problemas de sono, dores de cabeça e angústia do que os rapazes. A maioria destes avaliou sua saúde como boa e ótima e estão mais satisfeitos com a vida, com a alimentação e com a atividade física, em comparação com as moças. Contudo, estas se sentem mais satisfeitas do que os rapazes com relação à sexualidade. Salienta-se a importância de mais estudos avaliando os aspectos psicossociais dos adolescentes, como forma de identificar desvios e problemas que podem trazer conseqüências futuras a idade adultaAdolescence constitutes a critical step on the development of each individual characterized as a period of risks, problems and conflicts. Due the fact that in this period the subject starts to take a larger number of decisions and chooses among different alternatives, it is also considered the fact that many behavior standards acquired during adolescence among some health problems may last for the hole life; it turns to be essential to know the health behavior of the adolescents and the lack of satisfaction on the prevention way to avoid an undesirable future. The study investigated, through the appliance of two questionnaires sent to students and their parents, psychosocial aspects of 720 adolescents (252 boys and 468 girls) from 16 to 17 years old from public schools of Florianopolis/SC. Differences among the studied groups through the Parson's qui-squared test revealed that girls presented more sleep, headache and anguish problems than boys. Great part of the subjects considered their health as good and they are satisfied with life, with feeding and physical activities compared to girls. However, related to sexuality, girls appeared to be more satisfied than boys. It points out the importance of more studies evaluating the psychosocial aspects of adolescents as a way to identify deviances lines and problems that may bring future consequences at the adult age

Renormalization of the Higgs sector in the triplet model

We study radiative corrections to the mass spectrum and the triple Higgs boson coupling in the model with an additional Y=1 triplet field. In this model, the vacuum expectation value for the triplet field is strongly constrained from the electroweak precision data, under which characteristic mass spectrum appear at the tree level; i.e., $m_{H^{++}}^2-m_{H^+}^2\simeq m_{H^+}^2-m_A^2$ and $m_A^2\simeq m_H^2$, where the CP-even ($H$), the CP-odd ($A$) and the doubly-charged ($H^{\pm\pm}$) as well as the singly-charged ($H^\pm$) Higgs bosons are the triplet-like. We evaluate how the tree-level formulae are modified at the one-loop level. The $hhh$ coupling for the standard model-like Higgs boson ($h$) is also calculated at the one-loop level. One-loop corrections to these quantities can be large enough for identification of the model by future precision data at the LHC or the International Linear Collider.Comment: Published version in Physics Letters

Big-Data-Driven Materials Science and its FAIR Data Infrastructure

This chapter addresses the forth paradigm of materials research -- big-data driven materials science. Its concepts and state-of-the-art are described, and its challenges and chances are discussed. For furthering the field, Open Data and an all-embracing sharing, an efficient data infrastructure, and the rich ecosystem of computer codes used in the community are of critical importance. For shaping this forth paradigm and contributing to the development or discovery of improved and novel materials, data must be what is now called FAIR -- Findable, Accessible, Interoperable and Re-purposable/Re-usable. This sets the stage for advances of methods from artificial intelligence that operate on large data sets to find trends and patterns that cannot be obtained from individual calculations and not even directly from high-throughput studies. Recent progress is reviewed and demonstrated, and the chapter is concluded by a forward-looking perspective, addressing important not yet solved challenges.Comment: submitted to the Handbook of Materials Modeling (eds.
