Representações sociais de enfermeiros brasileiros e portugueses sobre o estresse em serviço de urgência

This study aimed to analyze the social representations of Brazilian and Portuguese nurses on stress in the emergency service. A semi-structured interview and the free word association test, with "stress" as the inductive stimulus, were used as research instruments. Data were collected from 120 nurses, being 60 from an emergency hospital in the city of Natal, Brazil and 60 from an urgency hospital in the city of Aveiro, Portugal. Data from the word association test were analyzed with the EVOC 2002 program, after thematic categorical content analysis, enabling construction of a data bank. Data gathered from the interview were analyzed by ALCESTE 4.8 software. Nurse represent the stress in the urgency department as a generation of physical and mental detrition where adaptation is unsatisfactorily, resulting in the onset of fatigne, irritability, lack of concentration, lack of motivation, pessimism, impaired interpersonal relationship and low productivity. The solution is part of a complex whole, which demands an integrated way of acting that has demanded increasingly professional attitudes based on multidisciplinarity

Desenvolvimento e validação de modelo de previsão para mancha preta dos citros em função de variáveis meteorológicas

A mancha preta dos citros é uma doença causada pelo fungo Guignardia citricarpa que produz lesões em frutos em variedades de laranja doce comerciais, causando a queda precoce dos frutos, diminuindo a produtividade e levando a sua depreciação para o mercado de fruta fresca. O objetivo do trabalho foi desenvolver e validar um modelo de favorabilidade climática da mancha preta dos citros relacionado a ocorrência dos sintomas da doença no Estado de São Paulo. Desenvolveu-se um sistema empírico com base em um banco de dados da ocorrência da doença e das condições climáticas, em campo, nos municípios de Barretos/SP e Gavião Peixoto/SP, durante as Safras 2007/2008 e 2008/2009. A variedade de laranjeira doce utilizada nos experimentos foi a 'Valência' enxertada sobre limoeiro 'Cravo', com 10 anos de idade. Para a incidência da mancha preta foi avaliada a porcentagem de frutos com sintomas na planta e para a severidade, a porcentagem de casca lesionada por fruto. Na análise de regressão as variáveis climáticas e os dados de intensidade de doença de Barretos foram selecionados no procedimento 'stepwise'. As melhores equações de regressão foram selecionadas pelo coeficiente de determinação (R²) e pela significância da regressão no teste F (P < 0,05 e P < 0,01) que resultou na equação Y= -502,43 + 9,61 X10 + 4,78 X30 + 0,54 X46 - 7,9 X50 em que Y=Índice de Favorabilidade, X10 é a temperatura média, X30 é a umidade relativa média, X46 é o molhamento foliar e X50 é a temperatura média durante o molhamento foliar, determinados com dados de intervalos de sete dias. Procedeu-se a validação no campo no município de Gavião Peixoto durante a Safra 2008/2009, realizando a correlação entre a incidência e severidade observadas no experimento e os dados previstos que foram os determinados pela equação, sendo que a correlação mostrou-se positiva para a incidência da doença com um R²=0,87.

A participação das mães no conselho escolar do CMEI Amor de Mãe

This research aims to study the participation of mothers in the School Council of the Centro Municipal de Educação Infantil Amor de Mãe. The goal is to understand the relationship among concepts that mothers have and their practices as advisors. The historical-philosophical approach taken along the research permitted working with real people and not those derived or idealized ones. It searched an approximation of the mode of being and living of the councilor mothers in their homes, and the concepts and practices in the School Council. It was inspired by ethnographic researches to describe data, habits, cultural practices, meanings and values of people involved. As sources of research, we used: interviews with mothers and school staff; documentary and photographic collection of CMEI Amor de Mãe; local and national legislation; notebooks of the National Program for the Strengthening of School Council (2004); data bank of dissertations and theses of the Post-Graduate Program in Education of the UFRN dealing with democratic management and the relationship school and family. The study indicates the existence of a narrative of the school community that shows mothers as "missing" or "passive" and a practice that point out to how people participate actively in the school routine. This contradiction reveals the existence of a historically constructed school mindset that is rooted in a model of family and school that differs from the reality found in CMEI Amor de Mãe and how families served by CMEI Amor de Mãe organize themselves. It is recommended that the school community and families reorganize the conceptions that guide their practices in educating and caring for children with whom they live and work to make progress together in managing this process

Random regression analyses using B-spline functions to model growth of Nellore cattle

The objective of this study was to estimate (co)variance components using random regression on B-spline functions to weight records obtained from birth to adulthood. A total of 82 064 weight records of 8145 females obtained from the data bank of the Nellore Breeding Program (PMGRN/Nellore Brazil) which started in 1987, were used. The models included direct additive and maternal genetic effects and animal and maternal permanent environmental effects as random. Contemporary group and dam age at calving (linear and quadratic effect) were included as fixed effects, and orthogonal Legendre polynomials of age (cubic regression) were considered as random covariate. The random effects were modeled using B-spline functions considering linear, quadratic and cubic polynomials for each individual segment. Residual variances were grouped in five age classes. Direct additive genetic and animal permanent environmental effects were modeled using up to seven knots (six segments). A single segment with two knots at the end points of the curve was used for the estimation of maternal genetic and maternal permanent environmental effects. A total of 15 models were studied, with the number of parameters ranging from 17 to 81. The models that used B-splines were compared with multi-trait analyses with nine weight traits and to a random regression model that used orthogonal Legendre polynomials. A model fitting quadratic B-splines, with four knots or three segments for direct additive genetic effect and animal permanent environmental effect and two knots for maternal additive genetic effect and maternal permanent environmental effect, was the most appropriate and parsimonious model to describe the covariance structure of the data. Selection for higher weight, such as at young ages, should be performed taking into account an increase in mature cow weight. Particularly, this is important in most of Nellore beef cattle production systems, where the cow herd is maintained on range conditions. There is limited modification of the growth curve of Nellore cattle with respect to the aim of selecting them for rapid growth at young ages while maintaining constant adult weight.

Determinação de dados de equilíbrio de fases para sistemas aquosos com eletrólitos

In the present work are established initially the fundamental relationships of thermodynamics that govern the equilibrium between phases, the models used for the description of the behavior non ideal of the liquid and vapor phases in conditions of low pressures. This work seeks the determination of vapor-liquid equilibrium (VLE) data for a series of multicomponents mixtures of saturated aliphatic hydrocarbons, prepared synthetically starting from substances with analytical degree and the development of a new dynamic cell with circulation of the vapor phase. The apparatus and experimental procedures developed are described and applied for the determination of VLE data. VLE isobarics data were obtained through a Fischer s ebulliometer of circulation of both phases, for the systems pentane + dodecane, heptane + dodecane and decane + dodecane. Using the two new dynamic cells especially projected, of easy operation and low cost, with circulation of the vapor phase, data for the systems heptane + decane + dodecane, acetone + water, tween 20 + dodecane, phenol + water and distillation curves of a gasoline without addictive were measured. Compositions of the equilibrium phases were found by densimetry, chromatography, and total organic carbon analyzer. Calibration curves of density versus composition were prepared from synthetic mixtures and the behavior excess volumes were evaluated. The VLE data obtained experimentally for the hydrocarbon and aqueous systems were submitted to the test of thermodynamic consistency, as well as the obtained from the literature data for another binary systems, mainly in the bank DDB (Dortmund Data Bank), where the Gibbs-Duhem equation is used obtaining a satisfactory data base. The results of the thermodynamic consistency tests for the binary and ternary systems were evaluated in terms of deviations for applications such as model development. Later, those groups of data (tested and approved) were used in the KijPoly program for the determination of the binary kij parameters of the cubic equations of state original Peng-Robinson and with the expanded alpha function. These obtained parameters can be applied for simulation of the reservoirs petroleum conditions and of the several distillation processes found in the petrochemistry industry, through simulators. The two designed dynamic cells used equipments of national technology for the determination of VLE data were well succeed, demonstrating efficiency and low cost. Multicomponents systems, mixtures of components of different molecular weights and also diluted solutions may be studied in these developed VLE cells

Saúde mental em operadores de petróleo do Rio Grande do Norte

The importance of identifying the consequence of the hours worked on people in society has been well recognized within Organizational and Work Psychology. From this point of view, the present research had the objective of analysing the effects of work regimes on the mental health of petroleum operators of Petrobrás. The sample totaled 144 subjects, corresponding to 27% of the work population. The mental health of the participants was evaluated using the following instruments of measurement: QSG-12, Scale of self-esteem, Scale of Positive and Negative Affections and the Scale of Valuable Attributes of IMST, each representing an empirical factor used to indicate and measure the five dimensions of mental health. The subjects perceptions of their work regime and the rest of their conditions of work were evaluated using scales of descriptive attributes of IMST, by applying a semi-structured questionnaire and by use of interviews. A socio-demographic file was used to collect information related to the biographical and socio-occupational profile of the worker sample. The answers to the questionnaire were inserted into the data bank of SPSS (Statistical Package for Social Science), for statistical analysis, and the interviews were analised based on the technique of Contents Analysis recommended by Bardin (1995). The main results revealed that one third of the worker sample were tense; however, the mental health of the majority was preserved. Cluster Analysis applied to the group of seven factors which measured the five dimensions of mental health identified four profiles of psychological well-being shared between members of the sample. It was observed that the people working in the system of Continuous Shift Alternation (TIR) and in the system of Pre-advising tended to present balanced and satisfactory profiles, while the ones which worked in the Administrative Field tended to present anxious and oscillating profiles, and thus were more affected psychologically. These were also the ones that also perceived the more negative aspects of their laborious conditions (reduced chances of self-improvement, physically stressful and financial resources below expectations with which to supply family and personal necessities. In agreement with the ecological model formulated by Warr (1987), the present study concluded that the positive and negative effects on the psychological well-being tended to occur as a consequence of the perceptions the petrol operators developed to face their work conditions

Lista de Cyanobacteria do Estado de São Paulo

Com base no levantamento bibliográfico realizado sobre as cianobactérias citadas para o Brasil e para o Estado de São Paulo em particular, além de consulta à lista de espécies da flora brasileira e aos bancos de dados de coleções paulistas, encontramos um total de 460 espécies citadas para o Brasil e 378 para o estado de São Paulo. Considerando que o grupo tem ao redor de 2800 espécies, estes números representam bem menos de 20% das espécies conhecidas. Assim, frente a diversidade de ambientes e habitats existentes nos biomas tropicais/subtropicais, o reduzido número de espécies já conhecidas indica que certamente essa biodiversidade está subestimada e deve ser muito maior do que identificamos até agora.

Fatores relacionados à adesão das drogarias e farmácias de Tatuí-SP no projeto Farmácias Notificadoras

Pharmacovigilance is accomplished by voluntary notification of suspected adverse reactions, medication errors, and deviations from quality, by users and health professionals, through the filling in of forms that are sent to a data bank. To broaden the sources of notifications, the National Health Surveillance Agency (ANVISA), in partnership with the Regional Pharmacy Council (CRF) and Center for Health Surveillance (CVS) of each state, introduced the scheme of Notifying Pharmacies. The present study was aimed at determining the factors influencing the decision of drugstores and private pharmacies in Tatuí/SP in 2007, to join this project A descriptive, observational survey of knowledge, attitude and practice (KAP) was applied to volunteer pharmacists in the town. The results showed that the professionals are awave of pharmacovigilance, (95.24%) and have attitude (95.24%). However, practice is limited (6.0%). Based on this information we concluded that the low support of the project was due to lack of time, interest and no information about the benefits to society of such activity and a lack of support from the pharmacists' organizations. This situation is expected to change with the current introduction of a professional profile, the fusion of professional bodies and the promotion of social awareness on pharmacovigilance.
