This work is a study of strategic management of catering establishments in the tourist route from Natal, through the study of the strategic profile of the manager and the level of satisfaction with the quality of services offered. Identifies the strategic profile prevalent in the studied sector, measures the level of customer satisfaction with services and associate the two constructs to distinguish the services of strategic profile. Uses population of 33 restaurants, built for convenience, from a list composed establishments associated with the Brazilian Association of Bars and Restaurants - ABRASEL, Veja magazine Christmas food and drink 2011/2012 and information from the natives. It presents statistical methodology used for descriptive bivariate analysis complemented by quantitative data. The quantitative characteristics of the population shows non-normality checked by the Shapiro-Wilks. Used the Kruskal-Wallis test for the realization of the association of variables and the Mann-Whitney test to perform post-test. It shows the strategic profile prevalent in the sector of restoration in Natal is the analyzer, although other types were detected. Notes that the level of satisfaction with the quality of service is getting a high score approximately 5 points in a 6-point Likert scale. Demonstrates that the client can tell the quality of services between the different strategic profiles. Identifies distinction between services provided by prospector profile compared to other profiles, indicating the size as the tangible aspects that presents noticeable difference. Certifies that these variables affect the environment of the restaurant in the building of strategic profile and reflect on the service provided. Concludes that the quality of services provided by catering establishments is influenced by the type of establishment and strategic profile of the study of this relation to establishments offering development opportunities and improving the quality of their services

Relevância do estado de hidratação na interpretação de parâmetros nutricionais em diálise peritoneal

OBJETIVO: Identificar determinantes do estado de hidratação de pacientes em diálise peritoneal crônica, bem como investigar os efeitos da sobrecarga líquida sobre o estado nutricional. MÉTODOS: Foi feito estudo transversal, realizado em 2006, avaliando 27 pacientes em diálise peritoneal crônica, acompanhados no Hospital das Clínicas da Faculdade de Medicina de Botucatu (SP), quanto a parâmetros clínicos, dialíticos, laboratoriais, antropométricos e de bioimpedância elétrica. Para avaliar a influência de parâmetros sobre o estado de hidratação empregou-se modelo de regressão linear múltipla. A amostra foi estratificada quanto ao estado de hidratação pela relação entre água extracelular e água corporal total (0,47 para homens e 0,52 para mulheres), parâmetros obtidos por meio de bioimpedância elétrica. Comparações foram realizadas por análise de covariância, Mann-Whitney, Qui-quadrado ou teste exato de Fisher. Considerou-se significância estatística quando p≤0,05. RESULTADOS: Pacientes com maior volume urinário e em modalidade dialítica automatizada apresentaram melhor estado de hidratação. Pacientes com maior sobrecarga líquida, comparados àqueles com menor sobrecarga, apresentaram menor ângulo de fase (M=4,2, DP=0,9 vs M=5,7, DP=0,7º; p=0,006), menor albumina (M=3,06, DP=0,46 vs M=3,55, DP=0,52g/dL; p=0,05) e maior % prega cutânea tricipital (M=75,3, DP=36,9 vs M=92,1, DP=56,9%; p=0,058), sem outras evidências antropométricas. CONCLUSÃO: Pode-se sugerir que os níveis reduzidos de albumina e ângulo de fase nos pacientes com maior sobrecarga líquida não estiveram relacionados a pior estado nutricional. Para o diagnóstico nutricional em vigência de sobrecarga líquida, deve-se considerar o conjunto de variáveis obtidas por diversos métodos, buscando relacioná-las e interpretá-las de maneira abrangente, possibilitando um diagnóstico nutricional fidedigno.

Gestão Sustentável da água: um estudo da conscientização ambiental em atividades residenciais urbanas

The search for sustainable solutions through an appropriate environmental administration of the available natural resources, that comes from encounter to the aspirations of preservation of the environment and of the human being, in way to diagnose and to solve the environmental and social problems with the smallest possible impact to the nature and the man, it is the great challenge, so much for that generation, as for the future generations. The study of the environmental problems of the water and the participation and the social actors' environmental understanding as a whole, interferes in the field of the thematic environmental international, contemplating the strategic need of an appropriate administration of that very natural one, through a program returned to the diagnosis of the problems and in the search of compatible maintainable solutions, in a social and environmental politics of planning and environmental education, centered above all in the citizen's voice , user of that system. The present thesis she seeks to study the problem of the maintainable administration of the water, focusing the participation and the citizen's environmental understanding in the use of that very natural one for urban residential activities, in what concerns the approach and analyses of variables that treat of the measurement of general knowledge and you adapt, sense of community of the access to the means of information and of the attitudes and environmental behaviors, besides the variables of partner-demographic characterization or personal identification of the interviewed ones of an exploratory research of the type " survey ", accomplished through a stratified aleatory sampling, being the strata each one of the 4 (four) Political-Administrative Areas of the Natal city, having happened the collection of the data in the period of february to april/2002. The methodology used in this work it constitutes in the application of questionnaires with scales of the type Likert to measure the echo-varied of the study, besides a partner-demographic scale for the characterization of the studied sample. For the analysis of the results, it was made an exploratory descriptive study initially, followed by the use of techniques statistical multivariate s, such as, factorial analysis through the application of main components, besides the accomplishment of studies of multiple lineal regression. To complement this study, the accomplishment of Tests of Independence was proceeded through the Qui-square of Pearson, in way to verify the dependence of the associations between the partner-demographic variables and the principal selected variables and presents in the resulting factors of the factorial analysis. The results appear for a low level of environmental knowledge, of access to the information and community's sense, besides the verification that the principal factors resultants send for the need of feeling emphasis in the programs and administration actions addressed for the environmental understanding, the behaviors and attitudes that approach the information and the environmental education, besides the reuse of the water

Clinical features associated to refractory obsessive-compulsive disorder

Some patients with obsessive-compulsive disorder (OCD) exhibit an unsatisfactory reduction in symptom severity despite being treated with all the available therapeutic alternatives. The clinical variables associated with treatment-refractoriness in OCD are inconsistently described in the literature.Methods: To investigate factors associated with treatment-reftactoriness of patients with OCD, we conducted a case-control study, comparing 23 patients with treatment-refractory OCD to 26 patients with treatment-responding OCD.Results: the factors associated with refractoriness of OCD were higher severity of symptoms since the onset of OCD (P < 0.001), chronic course (p=0.003), lack of a partner (p=0.037), unemployment (p=0.025), low economic status (p=0.015), presence of obsessive-compulsive symptoms of sexual/religious content (p=0.043), and higher scores on family accommodation (P < 0.001). Only the three latter variables remained significantly associated with treatment-reftactoriness after regression analyses. Limitations: small sample size, the biases and drawbacks inherent to a case-control study, and the inclusion criteria used to define the study groups may have limited the generalisation of the results.Conclusion: A major strength of this study is the systematic and structured evaluation of a vast array of variables related to the clinical expression of OCD, including epigenetic factors and ratings derived from instruments evaluating family accommodation. The presence of sexual/religious symptoms, low economic status and high modification on family function due to OCD were independently associated with, treatment-refractoriness. Future longitudinal studies are warranted to verify if these variables represent predictive factors of treatment non-response. (c) 2006 Elsevier B.V. All rights reserved.

Estudo comparativo entre os métodos LSAB®+ e Herceptest® para a detecção de HER-2/neu em carcinoma de mama

INTRODUÇÃO: A hiperexpressão de human epidermal growth factor receptor (HER-2/neu) e a amplificação do seu gene são indicadores de formas mais agressivas do câncer de mama. A Food and Drug Administration (FDA) aprovou o teste denominado HercepTest® com a finalidade de selecionar pacientes com indicação para o uso de um anticorpo humanizado anti-HER-2/neu (trastuzumab), com efeito terapêutico comprovado. OBJETIVOS: O presente trabalho tem como objetivo comparar os resultados obtidos pelos métodos imuno-histoquímicos LSAB®+ com a utilização de anticorpo A0485 e HercepTest®. Material e métodos: Foram utilizados 50 casos de carcinoma de mama nos quais a pesquisa da hiperexpressão de HER-2 pelo método LSAB®+ já havia sido realizada. Foi repetida a pesquisa da hiperexpessão de HER-2/neu nos mesmos casos, utilizando-se o método do HercepTest®. RESULTADOS: 34 casos foram considerados negativos pelos dois métodos, com escore 0 pelo método HercepTest®. Destes, 12 obtiveram escore 1+ e 22 obtiveram escore 0 pelo método LSAB®+. em oito casos, o escore foi 2+ pelos dois métodos. Escore 3+ foi encontrado também em oito casos pelos dois métodos. DISCUSSÃO: O método mais prático utilizado em laboratório de rotina diagnóstica para investigar a hiperexpressão de HER-2/neu é o estudo imuno-histoquímico. em função de muitas variáveis, como tempo de fixação, tipo de fixador, duração da fixação, método de recuperação antigênica e tipo de anticorpo utilizado, pode haver divergência de resultados. CONCLUSÃO: O presente estudo concluiu que o método HercepTest®demonstrou resultados equivalentes aos resultados obtidos pelo método LSAB®+ em carcinoma de mama.

Efeitos da transformação de uma variável com distribuição normal em sua inversa sobre os parâmetros de sua distribuição usando técnicas de Monte Carlo

Foram realizados quatro estudos de simulação para verificar a distribuição de inversas de variáveis com distribuição normal, em função de diferentes variâncias, médias, pontos de truncamentos e tamanhos amostrais. As variáveis simuladas foram GMD, com distribuição normal, representando o ganho médio diário e DIAS, obtido a partir da inversa de GMD, representando dias para se obter determinado peso. em todos os estudos, foi utilizado o sistema SAS® (1990) para simulação dos dados e para posterior análise dos resultados. As médias amostrais de DIAS foram dependentes dos desvios-padrão utilizados na simulação. As análises de regressão mostraram redução da média e do desvio-padrão de DIAS em função do aumento na média de GMD. A inclusão de um ponto de truncamento entre 10 e 25% do valor da média de GMD reduziu a média de GMD e aumentou a de DIAS, quando o coeficiente de variação de GMD foi superior a 25%. O efeito do tamanho dos grupos nas médias de GMD e DIAS não foi significativo, mas o desvio-padrão e CV amostrais médios de GMD aumentaram com o tamanho do grupo. em virtude da dependência entre a média e o desvio-padrão e da variação observada nos desvios-padrão de DIAS em função do tamanho do grupo, a utilização de DIAS como critério de seleção pode diminuir a acurácia da variação. Portanto, para a substituição de GMD por DIAS, é necessária a utilização de um método de análise robusto o suficiente para a eliminação da heterogeneidade de variância.

Características cefalométricas do padrão face longa

Este estudo determinou as características cefalométricas dos indivíduos portadores de Padrão Face Longa em comparação com indivíduos Padrão I. Um total de 73 telerradiografias em norma lateral, sendo 34 Padrão Face Longa e 39 Padrão I, foram selecionadas com base na morfologia facial, não considerando as relações oclusais e sagitais. Foram avaliados: padrão de crescimento facial, alturas faciais anteriores e posterior, relação maxilo-mandibular, além das relações dentárias com suas bases apicais. de uma forma geral, os indivíduos Padrão Face Longa apresentaram grandes desvios em relação aos indivíduos Padrão I, sendo a doença decorrente de um desequilíbrio entre os componentes verticais. Pôde-se observar que os valores das grandezas AFAT, AFAI, AFATperp, AFAIperp, 1-PP, 6-PP, 1-PM, SNB, ANB, ângulo goníaco, ângulo plano mandibular, além das proporções AFAI/AFAT e AFAIperp/AFATperp, estavam significantemente alterados para os indivíduos Padrão Face Longa. Com base nos resultados obtidos neste estudo, verificou-se que esses indivíduos caracterizavam-se pelo padrão de crescimento vertical e por um aumento da altura facial anterior inferior - conseqüentemente, da altura facial anterior total - estando a deformidade localizada abaixo do plano palatino. Foram observados ainda um retrognatismo maxilar e mandibular, além da presença de extrusão dentária anterior (superior e inferior) e póstero-superior, com os incisivos superiores bem posicionados em suas bases e os inferiores lingualizados.

The relationship between environmental variation and species abundance in shrimp community (Crustacea : Decapoda : Penaeoidea) in south-eastern Brazil

The impact of shrimp fisheries in tropical regions has become comparable to the world's most intensively exploited temperate shed ecosystems. The increase in the fishing fleet in south-eastern Brazil and the decrease in landings of profitable shrimp species have contributed to the incorporation of additional species into those fisheries. The goal of the present study is to investigate the influence of environmental factors on the abundance patterns of shrimp communities on the south-eastern coast of Brazil, over a period of two years. Monthly collections were conducted in the Ubatuba and Caraguatatuba regions using a commercial shrimp fishing boat equipped with 'double-rig' nets. Each region was divided into 7 sampling stations up to 35 m deep. The relationship between the environmental factors and the abundance patterns in the shrimp communities was assessed using a canonical correlation analysis (CCorrA). The first set of variables used during the CCorrA included environmental characteristics and the second set of variables the abundance of the studied species. A total of 374,915 individuals were collected during the present study. Xiphopenaeus kroyeri showed the highest abundance (273,127), followed by Artemesia longinaris (73,422), and Pleoticus muelleri (15,262). In the first root, depth and temperature showed the highest factor loadings (0.9 and -0.7) and canonical weights (0.6 and -0.4). These environmental factors were strongly associated with the abundance of X. kroyeri (factor loading = - 0.9 and canonical weight = - 0.9). The second root demonstrated a positive relationship between abundance of P. muelleri and depth, and an inverse association with bottom temperature. The abundance patterns of X. kroyeri and P. muelleri were strongly affected by the water mass South Atlantic Central Water (cold waters =15 degrees C), which can lead to a temperature decrease in deeper areas (> 15 m). Thus, the opposite abundance trend for depth of these species might reflect bathymetric variation in temperature, a clear example of distinct behavioural differences of species of different origins, either tropical (X. kroyeri) or subantarctic (P. muelleri). The low overall association between environmental parameters and shrimp abundance patterns indicates that each studied species might have responded idiosyncratically to environmental variation, such that a general community-level response was not apparent. However, other confounding factors such as intraspecific migration patterns might have also played a role in generating the observed patterns.

Aquatic macrophyte distribution in relation to water and sediment conditions in the Itaipu Reservoir, Brazil

Aquatic macrophyte community distribution along the eastern shoreline of the Itaipu Reservoir (one of the South America's largest impoundments) is described in relation to limnological and sedimentological factors. The central body of the reservoir is mesotrophic, while the arms (flooded influent river valleys) along the eastern shore may be oligo-mesotrophic to eutrophic, depending on time of year and sub-catchment characteristics. Macrophyte community composition and species cover were surveyed at 30 sites in four arms, in relation to sediment total P and organic matter; underwater light regime; and water total P and Kjeldahl N concentration, alkalinity, conductivity, depth and pH. Seventeen euhydrophyte and six emergent macrophyte species were recorded. Large stands of Egeria najas dominated the euhydrophyte vegetation, together with free-floating weed species (Pistia stratiotes Linn., Salvinia auriculata Aublet and Eichhornia crassipes (Mart.) Solms.). Canonical Correspondence Analysis of the data showed that two sets of variables were important predictors of aquatic macrophyte community structure. Floating macrophyte assemblage was closely related to concentration of nutrients in both water and sediment, while light penetration was the strongest predictor of submerged species occurrence. Although a large number of potential nuisance species were present, dense growths were restricted to shallower areas of the Itaipu Reservoir, causing localised problems. The possibility of increasing interference by these plants with fisheries, recreational use, transport and hydroelectricity generation suggests a need for continued monitoring of weed distribution and abundance, and investigation of appropriate management measures.
