Relations between the meaning attributed to work by first year university students and their academic and professional choice were analyzed. The participants were 921 students, 17-52 years old (M = 22; SD = 4.9), enrolled in 16 courses common to two college level institutions of the city of Natal, RN, one public, the other private. A questionnaire was designed for collecting data about the academic-professional choice, with open-ended and multiple choice questions. Work meaning was obtained by means of two questions on centrality and two scales pertaining to the Inventory of Motivation and Work Meaning: value and descriptive attributes. A socio-demographic set of questions ended the questionnaire. Data was entered in a SPSS (Statistical Package for the Social Sciences) database, allowing for the pertinent statistical analyses, such as frequency, t test, chi square, factor analysis, cluster analysis and ANOVA. Results indicated that the decision about academic-professional career was made by the majority of the participants (in first option, N = 921) without the adequate consideration of the socio-professional reality (80.7%) and personal internal resources (98.5%). When considering the second option (N = 654), only the first criterion was taken into account, but only by 12.5% of the sample. The main difficulties faced by students during the choosing process were, then, made apparent in the data. 46.8% of the participants were unsatisfied with the course they had started and were anticipating unpromising perspectives in relation to it. The first year students took work as the second most important aspect of their lives and demonstrated an idealized vision about it. Five patterns of work meaning were identified. In relation to centrality and the value and descriptive attributes, the university students displayed differentiation in the attribution of work meaning according to course and area of knowledge

This research aimed to analyze the dynamics established between the activity of the teacher in Distance Education (DE) and professional gender of teaching, in terms of impact of DE in teacher s usual professional activity. Previous studies showed that one of the central discussions concerning DE refers to the role that the teacher is called to perform. The present research, based on theoretical and methodological assumptions issued from Clinic of Activity, analyzed the impact referred above. This central aim was operationally executed along three main stages: 1) survey study for description of socio-professional profile of teachers working in DE in two universities from Natal (RN-Brazil), 2) clinical analysis of professional activity of teachers working in DE, taking into account four simultaneous levels of psychological constitution and development of human activity: personal, interpersonal, transpersonal and impersonal; 3) analytical focus on transpersonal context in order to understand the influence of pedagogical practice in DE on professional gender of teaching. Documental research, audio recorded voice data and a multiple choice Likert scale questionnaire concerning socio-professional information were used as procedural tools. The qualitative-clinical procedural tool of instruction to the double , firstly proposed by Clinic of Activity research group, was used in order to obtain oral productions concerning professional activity. Data issued from stage 1 (n=70, 28 men and 41 women) was submitted to descriptive and inferential statistical analyzes. 65.7% of the sample worked in a public institution, 30% in a private institution, and 4.3% in public and private institutions. 31.4% of the sample of participants was formed by teachers having a master degree, 28.6% were doctors and 26.3% had degrees of specialists. 54.3% of participants acted as remote tutor, and 44.3% were regents teachers. After descriptive multidimensional cluster analysis, two groups emerged (remote tutors and regents teachers), the most important variables in terms of contributions to this distinction being: professional function, level of graduate formation, level of income, activities and forms of entry in DE. Clinical analysis of data produced by two participant-teachers of each group, issued from instruction to the double technique, was performed. This analysis indicated the existence of different models of distance education. A general concern referring to the need of both taking into account information technology and pedagogical attitudes was detected. On the other hand, participant-teachers considered that participation in DE activities could bring relevant contributions to general professional gender of teaching. . Finally, teachers warned against certain formats of organization of teachers professional activity, as found in the domain of DE, since these activities could promote the intensification and individualization of teachers` work activity, and even the worsening of relations, rather than exchanges and shares through collective bargaining. This process could compromise the renew of the professional gender, by losing its historical roots and diminishing activity possibilities of teachers in their labor context

This study aims to analyze tourist information provided by the official websites of the 2014 FIFA World Cup host cities. The framework developed by Díaz (2005) was applied to analyze different aspects, such as: local tourist information, tourist services distribution, communication and interaction between website and users, and website foreign language versions. This dissertation describes how society and tourism are related by analyzing the consequences of technological evolution in the travel and tourism sector, showing the importance of the use of information and communication technology to provide accurate, upto- date and low-cost information to tourist destinations. Because of the nature of the study, the research subjects are the 12 Brazilian host cities represented by their respective official webpages (cities, states and convention bureaus), and also Brazil s official website, totalizing 36 elements to be analyzed. The methodology has been characterized as descriptive and exploratory with quantitative analysis, and also using desk research and survey literature review. In order to analyze the data collected, parametric and nonparametric statistics tests were used, such as: variance analysis (ANOVA and KRUSKAL-WALLIS) to measure means variance between groups combined with multiple comparison tests (Tukey and Games Howell); nonparametric correlations tests (Kendall s Tau b); and cluster analyses. Finally, Microsoft Excel was used to collect data and SPSS for managing data through quantitative analyses tests. Overall, the websites of the south region showed better results than the other Brazilian regions. Despite this result, the data analysis demonstrated that the available tourist information are incomplete as it was verified that tourist host cities websites are unable to provide all the information needed for the web visitors to organize and plan their journey. This means that visitors have to look for more information in other sources

The stocking of exotic fish, especially the tilapia, has become a common practice in the public reservoirs of the Brazilian semi-arid region. The stocking of tilapias has had as its main aim the improvement of the fisheries in the reservoirs and consequently the improvement of the socio-economic conditions of the families that have fishing as the main source of income. However, the environmental risks associated with this practice are high and can lead to a loss in aquatic biodiversity and to changes in the quality of the water. The object of this work was to quantify the socio-economic and environmental effects of the introduction of the Nile tilapia in the public reservoirs of the semi-arid northeastern Brazil. The analysis of the fish yield of 100 public reservoirs from 1970 to 2000 demonstrated that the introduction of the Nile tilapia apparently contributed to an increase in the total fish yield from the late 1970 s until the mid-1980 s. Nevertheless, from that time onwards the fish yield in these reservoirs has fallen into decline to levels inferior to those observed prior to the introduction of the tilápia. The analysis of the fishing activity statistics of the Gargalheiras reservoir located in the city of Acari, Rio Grande do Norte, demonstrated that the introduction of the Nile tilapia in the reservoir has not significantly increased the fish yield, the gross overall income, the gross per capita income nor the number of fishermen actively fishing in the reservoir. On the other hand, the analysis of the fishing activity statistics of the Gargalheiras reservoir has revealed a significant reduction in the captures of other commercially important fish species after the introduction of the tilapia. This result suggests that the Nile tilapia could have negatively affected other species of fish in the reservoir, contributing to the decline in their stocks. In order to assess the perception of the fishermen concerning the effects of the Nile tilapia over other species of fish and the quality of the water, questionnaires containing open and multiple choice questions were applied with 30 fishermen from the colony of the Gargalheiras reservoir. The great majority of the local fishermen stated that the tilapia is currently the most important species of fish to those who depend on fishing as a source of income and that they have not caused damage to other species of fish nor to the quality of the water in the reservoir. However, the results of the present work indicate that the alleged socio-economic benefits, employed to justify the introduction of the Nile tilapia in the reservoirs, are overestimated while the environmental impacts of the introduction of this exotic species are underestimated

The objective of the study was to determine the nutritional and chemical composition (carbohydrates, proteins, lipids, calcium, and iron), water and ash content, and the caloric value of powdered fruiting bodies from six strains and from a mixture of strains of the culinary-medicinal mushroom Agaricus brasiliensis. The Kruskal-Wallis nonparametric and multiple comparisons tests and the Pearson correlation coefficient were used, with a 5% significance level. First, the results showed that strain 99/30 had a similar nutritional composition to the mixed sample. Second, when comparing strain nutrients to the mixture nutrients, the highest levels of carbohydrates, proteins, and calcium were in strain 99/25, and the highest levels of lipids were in strains 97/11, 99/28, and 99/30. Strain 99/30 was highest both in caloric value and moisture content. Finally, the mixture was established as a good source of macronutrients and micronutrients, and strain 99/30 was the closest to the mixture in nutritional composition.

OBJETIVO: analisar a influência da via de parto sobre a força muscular do assoalho pélvico (FM-AP). MÉTODOS: estudo clínico de corte transversal, para avaliar a FM-AP pelo teste da avaliação da força do assoalho pélvico (AFA) e uso do perineômetro em primíparas, entre 20-30 anos de idade, 4-6 meses pós-parto. A contração, medida pelos dois testes, foi classificada em: zero - ausência, um - leve, dois - moderada e três - normal, sustentada por 6 segundos. Avaliaram-se 94 mulheres, entre 20 e 30 anos, divididas em três grupos: pós-parto vaginal (n=32); pós-cesárea (n=32) e nulíparas (n=30). A variável independente foi a via de parto e a dependente, a FM-AP. A comparação entre os graus de contração foi realizada pelo teste de Kruskal-Wallis e o teste de Dunn para comparações múltiplas; a influência da via de parto pelo teste chi2, o risco relativo (RR) para alteração da FM-AP e o coeficiente kappa para avaliar equivalência entre os testes. RESULTADOS: a mediana e 1º e 3º quartil da FM-AP foram menores (p=0,01) pós-parto vaginal (2,0;1-2) e intermediários pós-cesárea (2,0; 2-3) em relação às nulíparas (3,0;2-3), tanto analisadas pelo AFA como pelo perineômetro. Aumentou o RR de exame alterado pós-parto vaginal (RR=2,5; IC 95%: 1,3-5,0; p=0,002); (RR=2,3; IC 95%: 1,2-4,3; p=0,005) e pós-cesárea (RR=1,5; IC 95%: 0,94-2,57; p=0,12); (RR=1,3; IC 95%: 0,85-2,23; p=0,29) pelo PFSE e perineômetro, respectivamente. CONCLUSÕES: o parto vaginal diminuiu a força muscular do AP de primíparas quando comparado com os casos submetidos à cesárea e com as nulíparas.

Background: Since establishing universal free access to antiretroviral therapy in 1996, the Brazilian Health System has increased the number of centers providing HIV/AIDS outpatient care from 33 to 540. There had been no formal monitoring of the quality of these services until a survey of 336 AIDS health centers across 7 Brazilian states was undertaken in 2002. Managers of the services were asked to assess their clinics according to parameters of service inputs and service delivery processes. This report analyzes the survey results and identifies predictors of the overall quality of service delivery.Methods: The survey involved completion of a multiple-choice questionnaire comprising 107 parameters of service inputs and processes of delivering care, with responses assessed according to their likely impact on service quality using a 3-point scale. K-means clustering was used to group these services according to their scored responses. Logistic regression analysis was performed to identify predictors of high service quality.Results: The questionnaire was completed by 95.8% (322) of the managers of the sites surveyed. Most sites scored about 50% of the benchmark expectation. K-means clustering analysis identified four quality levels within which services could be grouped: 76 services (24%) were classed as level 1 (best), 53 (16%) as level 2 (medium), 113 (35%) as level 3 (poor), and 80 (25%) as level 4 (very poor). Parameters of service delivery processes were more important than those relating to service inputs for determining the quality classification. Predictors of quality services included larger care sites, specialization for HIV/AIDS, and location within large municipalities.Conclusion: The survey demonstrated highly variable levels of HIV/AIDS service quality across the sites. Many sites were found to have deficiencies in the processes of service delivery processes that could benefit from quality improvement initiatives. These findings could have implications for how HIV/AIDS services are planned in Brazil to achieve quality standards, such as for where service sites should be located, their size and staffing requirements. A set of service delivery indicators has been identified that could be used for routine monitoring of HIV/AIDS service delivery for HIV/AIDS in Brazil (and potentially in other similar settings).

Este artigo apresenta o desenvolvimento, validação e utilização de uma metodologia de avaliação da qualidade dos serviços de atenção primária do Sistema Único de Saúde (SUS), o Questionário de Avaliação da Qualidade de Serviços de Atenção Básica (QualiAB). Destina-se aos serviços de atenção básica, organizados segundo diferentes modelos de atenção, incluindo a Saúde da Família. Contém 50 indicadores sobre oferta e organização do trabalho assistencial e programático e 15 sobre gerenciamento, na forma de questões de múltipla escolha, autorespondidas via web pela equipe local do serviço. Confere a cada resposta valor zero, um ou dois; a média geral atribui ao serviço um grau de qualidade expresso pela distância do melhor padrão correspondente à média dois. Foi construído por processo de consenso interativo, que incluiu metodologias qualitativas, teste-piloto, aplicação em 127 serviços, validação de construto e confiabilidade. Respondido, em 2007, por 598 (92%) dos serviços de 115 municípios paulistas, mostrou bom poder para discriminar níveis de qualidade. Adotado em 2010 como parte de um programa de apoio à Atenção Básica da Secretaria de Estado da Saúde de São Paulo, foi respondido por 95% (2.735) dos serviços de 586 municípios (90,8% do Estado). Os resultados foram encaminhados aos municípios. O QualiAB fornece uma avaliação válida, simples e com a possibilidade de retorno imediato para gerentes e profissionais. Mostrou factibilidade, aceitabilidade, bom poder de discriminação e utilidade para auxiliar a gestão da rede de atenção básica do SUS em São Paulo. A experiência indica aplicabilidade nas redes de atenção básica do Brasil.

Objective: The purpose of this study was to evaluate the efficacy of the laser fluorescence (LF) device in detecting in vitro demineralization and remineralization of smooth surface caries-like lesions. Background Data: The early detection of smooth surface caries-like lesions is important to provide proper management of carious lesions, and allows monitoring of them over time. Also, some authors suggest that LF could be useful in monitoring the caries pathological process. Materials and Methods: Seventy-eight blocks of bovine teeth were obtained, and then submitted to artificial caries lesion induction and to a pH-cycling process. Superficial microhardness (SMH) and laser fluorescence analysis were performed at baseline, after induction of caries-like lesions, and after the pH-cycling regimen to promote remineralization. Results: Friedman's and multiple comparison tests were performed for all variables. SMH analysis showed significant differences (p < 0.05) between baseline (286.77 +/- 1.49 Vickers hardness number [VHN] units), before (38.48 +/- 0.85 VHN), and after remineralization (131.93 +/- 2.63 VHN). Baseline values for LF were extremely low (2.71 +/- 0.05), and a statistically significant difference was observed only after remineralization (3.61 +/- 0.08), as demonstrated by the increase in LF values. Conclusion: The LF device did not show efficacy for monitoring in vitro demineralization and remineralization of smooth enamel surfaces.

Para avaliar o comportamento de oviposição da mosca-branca, Bemisia tabaci (Genn.) biótipo B, em relação à posição da folha na planta, à área do limbo foliar, à idade da planta e à densidade de adultos na cultura do pimentão, foram realizados três testes, utilizando-se a cultivar de pimentão Magali-R. Os testes foram realizados em casa-de-vegetação e no Laboratório de Entomologia da DEFERS/UNESP, Campus de Ilha Solteira-SP. Nos testes com chance de escolha, plantas com 25, 30, 35, 40 e 45 dias de idade foram utilizadas para avaliar os efeitos da idade sobre a oviposição da mosca-branca, enquanto que em plantas com 35 dias estudou-se a distribuição de ovos da mosca-branca na planta e no limbo foliar. em plantas de 35 dias de idade, avaliou-se o efeito de diferentes densidades populacionais do inseto (50, 100, 150, 200 e 250 adultos/ planta) sobre o número de ovos depositados. No teste sem chance de escolha, utilizaram-se plantas com 35 dias de idade para avaliar o efeito das densidades sobre a oviposição da mosca-branca. B. tabaci biótipo B preferiu ovipositar da terceira a sexta folha a partir do ápice da planta localizadas nos terços médio e superior de planta de pimentão e nas áreas do limbo foliar localizadas nos lóbulos direito e esquerdo, próximas à base da folha. Plantas com 40 e 45 dias, são preferidas para oviposição e, em densidades de 200 e 250 adultos por planta, as moscas-brancas depositam ovos em número suficiente para diferenciar genótipos de pimentão com diferentes graus resistência a esta praga.

Avaliou-se a resistência (e antibiose) de genótipos de batata, comerciais e em fase de melhoramento, ao pulgão Myzus persicae, em ensaios efetuados com plantas em vasos, sem chance de escolha, em Jaboticabal (SP). Foram efetuados seis experimentos, utilizando-se um total de 16 genótipos, a saber: 'Achat', 'Apuã', 'Aracy', 'Aracy Ruiva', 'Bintje', 'Ibitu Açu', 'Itararé', 'N 140-201', 'NYL 235-4', '288.719-13', '288.764-26', '288.776-3', '288.776-6', '288.794-19', '288.801-6' e '288.814-7'. em cada experimento foram utilizadas combinações variadas dos mesmos. Nos dois primeiros experimentos as plantas foram infestadas com 30 pulgões adultos por planta, distribuídos em três folhas, com três avaliações realizadas em semanas subseqüentes à infestação, contando-se o número de indivíduos por planta. O terceiro experimento foi conduzido aprisionando-se duas fêmeas adultas no interior de pequenas gaiolas fixadas na face abaxial dos folíolos, em número de dez por planta, avaliando-se a reprodução do pulgão após sete dias, em dois plantios. No quarto experimento efetuou-se a infestação da planta com 15 pulgões, avaliando-se o crescimento da população na planta toda durante três semanas consecutivas. No quinto experimento foi avaliada a descendência de uma única fêmea adulta por folíolo e no sexto experimento avaliou-se o peso dos pulgões aos sete dias de vida. Os tricomas glandulares presentes nos folíolos e a funcionalidade dos mesmos também foram avaliados. A cultivar 'Ibitu Açu' apresentou elevado grau de antibiose a M. persicae; os genótipos '288.776-3' e '288.794-19' também apresentaram esse tipo de resistência, em grau moderado; '288.719-13' e '288.764-26' foram resistentes ao pulgão, provavelmente devido à presença de tricomas glandulares funcionais, dos tipos A e B, em seus folíolos (antixenose); entre os mais suscetíveis destacaram-se 'Bintje' e '288.801-6'.

O objetivo foi verificar a associação entre presença de deficiências físicas e hospitalizações na cidade de São Paulo, Brasil. Foi realizado inquérito de saúde na cidade de São Paulo em 2008. Utilizou-se processo de amostragem probabilística, estratificada (sexo/idade) e por conglomerados em dois estágios (setores censitários e domicílios). Os dados foram coletados por entrevistas por meio de um questionário estruturado, com 21 blocos, com a maioria das questões fechadas. A análise inferencial foi realizada com o uso de razões de prevalência (RP) bruta e ajustada e intervalo de 95% de confiança (IC95%) pelo método de regressão de Poisson. O módulo survey do programa Stata 9.2 foi usado para as análises, com significância de 5%. Foram entrevistadas 2.690 pessoas, com idade média de 38,75 anos (IC95%: 37,54-39,96). A hospitalização foi associada à deficiência (auditiva, RP = 1,59; física, RP = 3,77; múltipla, RP = 3,26). As pessoas com deficiência (auditiva, física - paralisia/amputação e múltipla) relataram internações com mais frequência que aquelas sem deficiência.
