The information tecnology (IT) has, over the years, gaining prominence as a strategic element and competitive edge in organizations, public or private. In the judiciary, with the implementation of actions related to Judiciário Eletrônico, information technology (IT), definitely earns its status as a strategic element and significantly raises the level of dependence of the organs of their services and products. Increasingly, the quality of services provided by IT has direct impact on the quality of services provided by the agency as a whole. The Ministério Público do Estado do Rio Grande do Norte (MPRN) deployments shares of Electronic Government, along with an administrative reform, beyond these issues raised, caused a large increase in institutional demand for products and services provided by the Diretoria de Tecnologia da Informação (DTI), a sector responsible for the provision of IT services. Taking as starting point strategic goal set by MPRN to reach a 85% level of user satisfaction in four years, we seek to propose a method that assists in meeting the goal, respecting the capacity constraints of the IT sector. To achieve the proposed objective, we conducted a work in two distinct and complementary stages. In the first step we conducted a case study in MPRN, in which, through an internal and external diagnosis of DTI, accomplished by an action of internal consulting and one research of the user satisfaction, we seek to identify opportunities of change seeking to raise the quality perceived of the services provided by the DTI , from the viewpoint of their customers. The situational report, drawn from the data collected, fostered changes in DTI, which were then evaluated with the managers. In the second stage, with the results obtained in the initial process, empirical observation, evaluation of side projects of quality improvement in the sector, and validation with the managers, of the initial model, we developed an improved process, gazing beyond the identification of gaps in service a strategy for the selection of best management practices and deployment of these, in a incremental and adaptive way, allowing the application of the process in organs with little staff allocated to the provision of information technology services

In this work we have elaborated a spline-based method of solution of inicial value problems involving ordinary differential equations, with emphasis on linear equations. The method can be seen as an alternative for the traditional solvers such as Runge-Kutta, and avoids root calculations in the linear time invariant case. The method is then applied on a central problem of control theory, namely, the step response problem for linear EDOs with possibly varying coefficients, where root calculations do not apply. We have implemented an efficient algorithm which uses exclusively matrix-vector operations. The working interval (till the settling time) was determined through a calculation of the least stable mode using a modified power method. Several variants of the method have been compared by simulation. For general linear problems with fine grid, the proposed method compares favorably with the Euler method. In the time invariant case, where the alternative is root calculation, we have indications that the proposed method is competitive for equations of sifficiently high order.

The contents introduction concerning the individual health cares reveals important since the school education. In this direction, the present study objectified to know an effect of Oral Health education intervention in the oral hygiene and in the schools children information level, of 4º e 5º basic education years. The study was composed by two groups, chosen of random form: control group (n = 115) and experimental group (n = 132), with 247 public net school children in total sample. The experimental group participated of some educative activities in Oral Health, with biweekly frequency, during the 4 months period, given for a surgeon-dentistry. Both the groups were submitted to a clinical examination for a previous verification of the Plaque Index (PI) and of Loe Silness Gingival Index (GI). A questionnaire with closed questions on Oral Health was applied before and after to verify the school children rightness index. After the intervention, the final data, represented for the PI, GI and Rightness Index verification, has been collected for statistical analyses through the chi-square test to a 95 % of reliable level, using the SPSS 10,0 software. The PI and GI were categorized in high and low on the initials index basis medium; already the Rightness Index was categorized in inadequate (< 50%) and adequate (≥ 50%). It was verified that the PI (p = 0,014; IC 0.24-0.86) and the GI (p = 0,013; IC 0,28-0,84) presented differences statistically significant, after the education activities, when compared to with the control, favoring the experimental group. It was verified too the experimental group got greater rightness index, presenting difference highly significant (p<0,0001; IC 3,73-26,81). It was still observed that there was no association between the oral hygiene indicators and the school children information level. Ahead the results, it can been concluded that education activities related in the school routine were capable to give positives effects in the oral hygiene control and in the information level about Oral Health, however, not necessarily, the individual with bigger information is that one who has practiced an oral hygiene more adjusted. One become necessary, however, that the education in Oral Health occurs of permanent and integrated form with others school actors, for the positive effect does not lose the student s life longterm

The new Evolutionary Psychology (E. P.) paradigm has been trying to understand how the human beings make their decisions over time regarding the most diverse variables, always bearing in mind that such a cognitive process is due to a complex natural selection process that occurred millions of years ago. One of the main topics discussed by this new paradigm is the issue of parental investment, i.e., the care the parents provide to an offspring at the expense of the investment into a new one. The present work sought to integrate these two topics, trying to understand how some variables modulate the process of decision making in a sample of the city of Natal, Rio Grande do Norte state. It was investigated the hypothesis that the presence of both parents, along the individual development, could signal a more favorable environment, providing clues to the individual that he could assume a competitive position at the socio-biological market. His decisions, therefore, could be guided by long-term investments with aims to obtain more robust rewards. On the contrary, those who has suffered for some moment the absence of one the parents could develop theirselves in a not so competitive way, starting to choose immediate benefits - but lesser ones -, since the future would be less predictable due to their worse development conditions. This study involved 152 individuals from three higher education institutions, one of them being public and the others being private ones. In the results found, there was no difference between children of coupled parents and children of deceased or divorced parents concerning discount rates. The levels of hopelessness did not affect the discount rates of children of single parents when compared to children of coupled parents. Not having one of the parents because of divorce made the child to tend to present lower scores in the domain of social relations of WHOQOL - Bref, whilst the absence of the father by death made the scores lower in the domain of environment. The results indicate that loosing one of the parents along the development influences the individual's quality of life perception, but the measurement method of future discounting rates by means of financial choices is not sensitive to this variation

No ano agrícola de 2006/07, no município de Selvíria (MS), foi analisada a produtividade do feijão em função de alguns atributos físicos de um Latossolo Vermelho distroférrico, cultivado nas condições de elevado nível tecnológico de manejo pelo sistema plantio direto irrigado com pivô central. O objetivo foi selecionar, entre os atributos pesquisados do solo, aquele com a melhor representatividade para explicar a variabilidade da produtividade agrícola. Foi instalada a malha geoestatística, para a coleta de dados do solo e da planta, com 117 pontos amostrais, numa área de 2.025 m² e declive homogêneo de 0,055 m m-1. do ponto de vista linear e espacial, a produtividade de feijão foi explicada em função da densidade de partículas e da umidade gravimétrica do solo, respectivamente. Assim, os valores de densidade de partículas entre 1,95 e 2,20 kg dm-3 e de umidade gravimétrica entre 0,205 e 0,239 kg kg-1; ambas coletadas na camada intermediária, resultaram em sítios com as mais elevadas produtividades (2.200-2.600 kg ha-1). Entretanto, para as condições do elevado nível tecnológico de manejo empregado, a produtividade média do feijão não atingiu seu máximo potencial, uma vez que o agravado estado de compactação no qual o solo se encontrava proporcionou à produtividade redução de 26,6 %. Dessa forma, os valores médios da densidade do solo e da resistência do solo à penetração, respectivamente nas faixas de 1,36-1,41 kg dm-3 e de 1,56-3,24 MPa, típicos de solos argilosos compactados, atestaram a substancial queda da produtividade de grãos de feijão.

The Car Rental Salesman Problem (CaRS) is a variant of the classical Traveling Salesman Problem which was not described in the literature where a tour of visits can be decomposed into contiguous paths that may be performed in different rental cars. The aim is to determine the Hamiltonian cycle that results in a final minimum cost, considering the cost of the route added to the cost of an expected penalty paid for each exchange of vehicles on the route. This penalty is due to the return of the car dropped to the base. This paper introduces the general problem and illustrates some examples, also featuring some of its associated variants. An overview of the complexity of this combinatorial problem is also outlined, to justify their classification in the NPhard class. A database of instances for the problem is presented, describing the methodology of its constitution. The presented problem is also the subject of a study based on experimental algorithmic implementation of six metaheuristic solutions, representing adaptations of the best of state-of-the-art heuristic programming. New neighborhoods, construction procedures, search operators, evolutionary agents, cooperation by multi-pheromone are created for this problem. Furtermore, computational experiments and comparative performance tests are conducted on a sample of 60 instances of the created database, aiming to offer a algorithm with an efficient solution for this problem. These results will illustrate the best performance reached by the transgenetic algorithm in all instances of the dataset

JUSTIFICATIVA E OBJETIVOS: A medicação pré-anestésica (MPA) é adjuvante da anestesia e diminui tanto a necessidade de concentrações elevadas de anestésicos como a ansiedade perioperatória, produzindo amnésia e contribuindo para estabilidade hemodinâmica. Dentre as drogas administradas na MPA de crianças, encontram-se o midazolam e a clonidina. O objetivo desta pesquisa foi avaliar se a MPA com midazolam e clonidina exerce influência no nível de hipnose, avaliado pelo BIS, em crianças após indução anestésica com propofol e alfentanil. MÉTODO: Participaram do estudo 30 pacientes, com idades entre 2 e 12 anos, estado físico ASA I, submetidos a cirurgias eletivas, que foram distribuídos em 3 grupos: G1 - sem MPA, G2 - midazolam (0,5 mg.kg-1) e G3 - clonidina (4 µg.kg-1), por via oral, 60 minutos antes da cirurgia. Todos os pacientes receberam alfentanil (30 µg.kg-1), propofol (3 mg.kg-1) e atracúrio (0,5 mg.kg-1). Avaliou-se o valor derivado do BIS antes da indução da anestesia (M1) e após a intubação (M2). O método estatístico utilizado foi a análise de variância para idade, peso e altura, e análise de perfil para o BIS, sendo o valor de p < 0,05 considerado significativo. RESULTADOS: Quando se comparou o mesmo momento (M1 ou M2) entre os três grupos, não foram observadas diferenças estatisticamente significativas. Quando se compararam os dois momentos de um mesmo grupo, M1 foi maior que M2 nos três grupos. CONCLUSÕES: A medicação pré-anestésica com midazolam e clonidina não influenciou o nível de hipnose em crianças induzidas com propofol e alfentanil.

FUNDAMENTO: A hipertrofia ventricular esquerda é potente preditor de mortalidade em renais crônicos. Estudo prévio de nosso grupo mostrou que renais crônicos com menor escolaridade têm hipertrofia ventricular mais intensa. OBJETIVO: Ampliar estudo prévio e verificar se a hipertrofia ventricular esquerda pode justificar a associação entre escolaridade e mortalidade cardiovascular de pacientes em hemodiálise. MÉTODOS: Foram avaliados 113 pacientes entre janeiro de 2005 e março de 2008 e seguidos até outubro de 2010. Foram traçadas curvas de sobrevida comparando a mortalidade cardiovascular, e por todas as causas dos pacientes com escolaridade de até três anos (mediana da escolaridade) e pacientes com escolaridade igual ou superior a quatro anos. Foram construídos modelos múltiplos de Cox ajustados para as variáveis de confusão. RESULTADOS: Observou-se associação entre nível de escolaridade e hipertrofia ventricular. A diferença estatística de mortalidade de origem cardiovascular e por todas as causas entre os diferentes níveis de escolaridade ocorreu aos cinco anos e meio de seguimento. No modelo de Cox, a hipertrofia ventricular e a proteína-C reativa associaram-se à mortalidade por todas as causas e de origem cardiovascular. A etiologia da insuficiência renal associou-se à mortalidade por todas as causas e a creatinina associou-se à mortalidade de origem cardiovascular. A associação entre escolaridade e mortalidade perdeu significância estatística no modelo ajustado. CONCLUSÃO: Os resultados do presente trabalho confirmam estudo prévio e demonstram, ademais, que a maior mortalidade cardiovascular observada nos pacientes com menor escolaridade pôde ser explicada por fatores de risco de ordem bioquímica e de morfologia cardíaca.

Being available as a tourist destination is a necessary condition but not enough for the expansion and success of tourism activity. To be successful, tourism requires investment, inputs, appropriate planning and management, like any other economic activity. A fundamental goal of the destination management is to understand how the competitiveness of a tourist destination can be improved and sustained. Competitive position of tourism can be measured and assessed by various models. Evaluating the indicators of competitiveness of a tourist destination involves a multivariate analysis, ranging from issues directly related to tourism activity itself to the indirect factors. These are elements that are interrelated and that together will point out the competitive condition of this destination. From the definition and characterization of competitiveness, sustainability and management in the context of tourist destinations, understood as the main concepts of this study, we present the main theoretical and methodological models of assessment of competitiveness of tourist destinations in the literature and represent the state of the issue in the scientific treatment of the subject. These models, designed by researchers from several countries and applied in different tourist destinations, are confronted about their structure, indicators considered and localities in which they were applied. The aim of this study was to know and evaluate the condition of tourist competitiveness of the destination Pólo Costa das Dunas, from the constraints attributes of superior performance of the evaluation model of tourist competitiveness of destinations Competenible, suggested by Mazaro, and that suit the requirements of international market aware of the strength and importance of sustainability. The condition of competitiveness of tourist destination in Rio Grande do Norte Pólo Costa das Dunas was moderate. The competitive strengths and weaknesses of the destination Pólo Costa das Dunas revealed through the dozens of sustainable attributes of the model Competenible showed guidelines and initiatives that can be taken to guide strategic decisions related to their planning and management. Thus, this study should serve as support for strategic planning and long-term management of the sector and as a crucial tool for making decisions related to public policies, sectoral investments, monitor processes, strategic planning, direction and control of the local and regional tourism development of destinations

The study aims to analyze the perception of managers on intangible assets as strategic and competitive resources in small hotels in Natal/RN, through the theory of the Resource Based View (RBV). This is a qualitative study of exploratory and descriptive, conducted with managers of the means of hosting small the capital of Rio Grande do Norte through semi-structured interviews, which was applied later, the technique content analysis based on the results of the information obtained in the interviews. Thus, research has shown that managers of small hotels visited (A, B, C) are not sufficient and satisfactory knowledge to set as their unique intangible assets of the company and makes use of them, on an occasional basis, without understanding or in essence understand its true value as a resource that can be used strategically for sustainable competitive advantage in the hotel market in Natal/RN. This means that managers do not know how to create new attributes and use them strategically. And they need to expand their partnerships with stakeholders. Given the importance of the subject of the present research, the information achieved by this analysis may contribute to the provision of information to establish a current situation with regard to the attributed to the knowledge and use of resources (intangible assets) importance as a strategic source and competitive for the internal management of the company by managers and thus, enabling a differential and greater economic profit over time in this segment

INTRODUÇÃO: Pacientes com doença renal crônica (DRC) apresentam menor tolerância ao exercício e baixa capacidade funcional, o que os torna, via de regra, sedentários. Outra alteração importante encontrada na DRC é a disfunção cognitiva. O sedentarismo tem sido associado à disfunção cognitiva na população geral, porém, poucos estudos avaliaram essa associação na DRC. OBJETIVOS: Verificar associação entre o nível de atividade física e a função cognitiva de pacientes com DRC que realizam hemodiálise (HD). MÉTODOS: Foram avaliados 102 pacientes que realizam HD. Os participantes responderam o Questionário Internacional de Atividade Física, que avalia o nível de atividade física e o Mini Exame do Estado Mental, utilizado para o rastreamento cognitivo. Os pacientes foram divididos em três grupos conforme a classificação do nível de atividade física (GI: ativos/GII: irregularmente ativos/GIII: sedentários). Foi aplicada análise de regressão logística adotando-se como variável desfecho a presença de disfunção cognitiva e preservando como variáveis independentes aquelas com probabilidade estatística de diferença entre os grupos inferior a 0,1. Foi considerado estatisticamente significante o valor de p inferior a 0,05. RESULTADOS: Os grupos foram semelhantes quanto à idade, tempo de HD, escolaridade e tabagismo. Apresentaram diferença estatisticamente significante quanto à raça, índice de massa corporal, presença de diabetes mellitus, doença de base e grau de déficit cognitivo. Quanto aos dados laboratoriais, os grupos diferiram quanto à creatinina, glicemia, hemoglobina e hematócrito. Houve associação entre o nível de atividade física e função cognitiva, mesmo ajustando-se para as variáveis de confusão. CONCLUSÃO: O maior nível de atividade física associou-se a melhor função cognitiva em renais crônicos em HD, independentemente das variáveis de confusão avaliadas.

Cette étude a été fondée sur la reconaissance, la description et l'analyse du circuit spatial de la production de l activité des fabriques des casquettes dans la région du Seridó Potiguar. L activité des fabriques des casquettes est située dans les villes de Caicó, Serra Negra do Norte e São José do Seridó, qui forment le pôle de fabriques de casquettes, composé de soixante-quatre (64) unités de fabrication, le deuxième plus grand producteur de casquettes au Brésil. Dans la condition de base géographique, l'opérationnalisation du concept de circuits spatiales de la production a été essentielle à la compréhension de l'utilisation du territoire et de l'indivisibilité de l'espace, du fournisseur de matières premières au consommateur final, comprenant les étapes des matières premières, la main-d'oeuvre, le stockage, les transports, le commerce et la consommation dans la période actuelle, dans laquelle les instances de la production, la circulation, la distribution et de la consommation sont spatialement diffus. Sur la base de l'identification et de la localisation de ces étapes et des principaux acteurs impliqués dans la activité des fabriques de casquettes, une configuration de circuit spatial de la production a été élaborée, en s'interprétant l'utilisation des territoires par les instances productives. L'interprétation des étapes de production a identifié que les entreprises liées à l'Association Seridoense des Fabricants de Casquettes agissent plus efficacement sur le territoire que celles nonassociées, alors que toujours elles investissent dans des nouveaux équipements, en augmentant sa puissance technique pour se renforcer avant un marché si compétitif comme celui des casquettes. En examinant la contribution de la fabrication des casquettes à l'utilisation actuelle des territoires de la coupe, nous avons appris que les activités complémentaires et des matières premiéres nécessaires à sa réalisation se trouvent dans leur environnement géographique. Ainsi, la proximité spatiale entre les étapes de la fabrication des casquettes fait entrevoir la matérialité du territoire, conférée dans la coexistence des techniques passées et présentes, et l'ensemble des actions effectuées par un certain nombre de travailleurs sociaux qui collaborent à la création du circuit spatial de la production de l activité des fabriques des casquettes. Cette étude a confirmé que les fabriques des casquettes sont organisées sous la forme de cellules de production, continues ou discontinues, dont les équipements et les machines à coudre industrielles obéissent à la logique d'une production de plus en plus standardisée. Ce circuit spatial de la production contribue à l'utilisation actuelle des territoires de Caicó, Serra Negra do Norte et de São José do Seridó car il amplifie le mouvement du commerce et des relations entre les lieux, à travers la dynamique des flux des personnes, des biens et des produits, en constante circulation, guidées par la division du travail entre les étapes productives

O experimento foi conduzido com o objetivo de avaliar o efeito da linhagem e do nível de lisina da dieta sobre o rendimento e a qualidade da carne de peito de frangos de corte. Foram utilizados 2250 pintos não sexados, de três linhagens comerciais, identificadas como A, B e C, distribuídos em delineamento inteiramente casualizado em esquema fatorial 3x3 (linhagens e níveis de lisina), com cinco repetições de 50 aves. As aves receberam ração à vontade, à base de milho e farelo de soja, suplementadas com 1,18; 1,24 e 1,30% de lisina nas rações pré-iniciais (1 a 7 dias); 1,10; 1,16 e 1,22% nas rações iniciais (7 a 21 dias); 1,0; 1,06 e 1,12% nas rações de crescimento (21 a 35 dias) e 0,85; 0,91 e 0,97% nas rações de terminação (35 a 42 dias). Foram avaliadas as características de rendimento de peito e carne de peito e as medidas de espessura, largura, comprimento, pH, perda de peso por cozimento e força de cisalhamento da carne de peito. Para o rendimento de peito não foram observadas diferenças significativas, enquanto para rendimento de carne de peito houve efeito significativo da linhagem, em que a linhagem A apresentou o maior rendimento e a linhagem B, o menor. Para as medidas físicas da carne do peito, foram encontradas diferenças significativas entre as linhagens para comprimento de peito, com a linhagem C apresentando o maior resultado. O pH da carne diferiu significativamente para linhagens e níveis de lisina. As linhagens tiveram efeito sobre o rendimento, comprimento e pH da carne de peito, em que a linhagem A apresentou maiores valores para rendimento e pH e a linhagem C para comprimento.
