Influência do pré-aquecimento na adaptação marginal de dois materiais seladores de fóssulas e fissuras, analisada através de tomografia de coerência ótica

Among the non-invasive techniques employed in the prevention of caries highlights the sealing pits and fissures which is a conservative maneuver, in order to obliterate them to protect them from attack acid bacteria. Influenced by the studies of pre-heating composite resin, which has experienced great improvement in some of their physical properties, this study aimed to evaluate in vitro the superficial and internal marginal adaptation of different materials and sealants in pre-heating or not. A total of 40 extracted human third molars (n=10) that had their occlusal surfaces prepared to receive sealant. We tested two types of sealing materials: resin sealant (Fluoroshield) and low-viscosity resin (Permaflo), where 50% of previously received heated material and the other half received sealant material at room temperature. All samples were subjected to thermal cycling and pH, simulating a cariogenic oral environment, and later were analyzed appliance OCT (optical coherence tomography). The images obtained alterations were recorded and analyzed statistically. Change was considered as the emergence of bubbles, gaps and cracks in the sealant. Comparisons of the same material, assessing the fact that it is not sealed or preheated material, as well as comparisons between different materials subjected to the same temperature were carried out. The nonparametric Tukey test was used (p < 0,05). The results showed that there was statistically significant difference between both the materials analyzed, as between the situations in which the sealant material was submitted (preheated or not). On the issue of marginal adaptation and internal surface, seen through Optical coherence tomography, may suggest that there is a difference between the use of one type or another of the sealing material analyzed, with superiority attributed to resin Permaflo compared to sealant Fluroshield, telling is the same for the different techniques used

Marketing de relacionamento em um provedor de internet: um estudo comparativo que considera a visão gerencial e a percepção dos clientes

The current paper aims at analyzing customer retention in Internet provider services. For this study, we sought to understand what are the client's expectations regarding the services available and compare them with management perception in relation to the use of those services. Identifying the coherence level between the two points of view, management and client, it is possible to pinpoint how service is assessed in real conditions. Then, from this point on, a new vision can be implemented on available services, and new customer service strategies aiming at best serving to their expectation and need, can be rethought. The exploratory research was utilized. It was based on case study, and quantitative and qualitative methods were used. The quantitative method was done by applying the cluster technique with six variables of control derived from the six main services, whose definition was done through qualitative survey of the internal management team. Then, an structured interview with 443 clients, from a probabilistic sample of 800 costumers. The total number of active clients of the internet provider is of 10.677. Client perception in relation to services varied, if compared with the four services that were under the managerial metric method, this comparison showed a more positive evaluation than the real use of the service. Thus, it was observed that the value of each service available for the client depends on his/her perception of it, regardless of using or not the offered service. As a result, it is possible to understand which services offered by the company under study effectively contribute to a good client-company relationship, and the upkeep of those clients

As pessoas na organização e o (re)alinhamento estratégico: o modelo de gestão da Alesat combustíveis em Natal/RN

Este trabalho consiste num estudo de caso na empresa Alesat cujo objetivo geral foi compreender o modelo de gestão de pessoas adotad por uma empresa norteriograndense à luz do modelo estratégico de gestão de pessoas. O estudo baseouse na literatura de Albuquerque (2002); Ashton, Haffenden e Lambert (2004); Fischer (2002); Legge (1995); Mascarenhas (2008); Tanure, Evans e Pucik (2007), Ulrich (2000) e Vasconcelos (2006), dentre outros, paa apreender como os profissionais que atuam no delineamento de estratégias e operacionalização das ações de recursos humanos concebem o seu posicionamento e eventual alinhamento à estratégia organizacional. O método analisou e descreveu o modelo de gestão de pessoas da empresa campo do estudo. A coleta de dados contou com a realização de entrevistas semi-estruturadas com os 05 gestores de RH que atuam na matriz (Natal/RN). Também foram coletados dados secundários, além de documentos e comunicações internas da empresa que tocam ao RH. Os dados coletados foram analisados à luz da análise de conteúdo de Bardin (1977). Através da análise, foi possível identificar políticas e práticas de RH que perpassam um modelo de gestão de pessoas bem definido e consolidado, com impactos mensuráveis no desempenho organizacional. Percebeu-se, também, a forte disseminação de uma cultura organizacional com foco no posicionamento estratégico e na informalidade e proximidade das relações, que permeiam o modelo de gestão de pessoas. Concluiuse a coerência entre as políticas estratégicas da empresa e as de recursos humanos. A pesquisa apreendeu as interfaces do modelo de gestão estratégica de pessoas da empresa; estas implicam uma alternância entre pensamentos e atitudes vinculados à versão hard, onde o papel das prática de RH é garantir que as pessoas alcancem os objetivos empresariais; e à versão soft, onde o papel do RH é desenvolver o capital intelectual e humano para diversificar os negócios e alcançar resultados sustentáveis e diferenciados. O salto qualitativo atingido pela Ale pode ser atribuído ao fato de possuir um RH situado hierarquicamente na alta cúpula da empresa, em posição de consultoria interna o que oferece perspectivas de atuação que vão muito além das rotinas operacionais desenvolvidas por boa parte das empresas no Brasil

Estrutura de organizações sociais: adaptação aos projetos sociais ou às pressões institucionais?

This is a study concerning in the structure of non governmental organizations, based on the institutional theory. It aims to understand the relation among structure, social projects and environmental influences, analyzing if there is coherence with project social or expresses adaptation to the institutional pressures of the environment. It introduces as theoretical support for the themes, studies about institutional theory and social structure. The research is descriptive and exploratory; it also applies to a study of case, based on the technical procedures. From the research universe, that was compound by non governmental organizations from Natal, RN, Brasil, it was chosen the Casa Renascer, a non governmental organization that works with the combat to the violence and sexual exploration of children and teenagers. The data collection process employed includes documental research, observations and semi structured research devices, guided by the organizational process proposed by Serva (1996) and by the institutional theory. The collected data were qualitatively treated. The analysis was divided into three parts, following the research matters. The social project characterization demonstrated that the organization went by three main phases. The first one, characterized by focus in women and girls education and health; the second shows the emphasis on girls in social risk situation, with preventive approach; and the last one, characterized by victims assistance of violence and sexual exploration. From the analysis using the institutional theory mechanisms, the results showed that exists coherence between structure and environmental influences, but a weak coherence between structure and social projects. It indicates as main determinant of the structure, an aspect forgotten by the institutional theory, the power. It was observed the presence from normative, coercive and mimetic mechanisms, highlighting normative influences

Sobre projetos, palavras e imagens: relacionando textos e desenhos nos trabalhos finais de graduação em arquitetura e urbanismo

This research continues the current debate about the role of the images and the words in the architectural design persuasion, where we emphasize the increasing valuation of written documents (FORTY, 2004; MARKUS; CAMERON, 2002), the seduction for the graphical representation (DURAND, 2003) and the rhetorical effects of the graphical and textual resources (TOSTRUP, 1999). Based on these quarrels, we look for verify in the graduate final projects the relation between the design texts and images. From the PROJEDATA, database of the PROJETAR research group (UFRN), we selected the final projects of two brazilians universities, UFRN and USP, that in a first analysis, they had shown as ideal types of two distinct design presentation models, respectively: texts and drawings in separated documents, or combined in an only support. Based on Markus explanation about the function and the content of the texts, on the Durand perspective with regard to graphical representation uses and on Tostrup point of view concerning the rhetorical potential of texts and drawings, we analyze, in a set of 25 projects, how the students relate the textual and imagetical speeches. For this, we related the focus of each speech, in order to verify the possible coherence between both. We conclude that in the model of USP final project the coherence between the texts and the drawings is clearer than in the model adopted in UFRN

Tradução, adaptação cultural e análise das propriedades psicométricas do activities of daily living questionnaire - ADLQ - para avaliação funcional de pacientes com a doença de alzheimer

O Activities daily living questionnaire - ADLQ foi elaborado para avaliar atividades básicas e instrumentais em pacientes com a doença de Alzheimer. O objetivo principal deste estudo consistiu em realizar a tradução do ADLQ para a língua portuguesa, adaptação transcultural e análise das suas propriedades psicométricas. A amostra foi composta por 60 pacientes e os respectivos 60 cuidadores. O estudo iniciou-se com a tradução do instrumento pela técnica de retrotradução associada ao método bilíngüe. A versão traduzida foi respondida pelo cuidador e o Mini Exame do Estado Mental (MEEM) aplicado ao paciente. A análise psicométrica foi realizada através da validade das medidas do instrumento. Os resultados verificaram uma correlação inversamente significativa (r=-0,793;p<0,05) entre os instrumentos avaliados, com uma explicação da variância total de 62%. A coerência interna do instrumento foi realizada através da correlação com os resultados do MEEM sugerindo uma versão condensada do ADLQ. Avaliando-se através do teste t para amostras correlacionadas, as médias do ADLQ-versão traduzida e versão condensada não apresentaram diferenças significativas, demonstrado assim que a simplificação do instrumento não alterou os valores do nível de dependência funcional observados. A análise fatorial realizada através da rotação Varimax indicou seis dimensões. Atividades como; comer, vestir-se, banho, necessidades fisiológicas, tomar comprimidos, participação em grupos, administrar finanças, manusear dinheiro, locomover pela vizinhança, usar telefone, compreensão, dentre outras, são os mais importantes preditores da capacidade funcional, no grupo estudado. Atividades com desempenho pouco comum a ambos os sexos, e no desempenho de papéis sociais enquanto gênero na sociedade brasileira (afazeres domésticos, consertos e manutenção em casa), na amostra estudada, não demonstraram ter importância na determinação da capacidade funcional com o paciente com a Doença de Alzheimer. O presente estudo disponibiliza uma nova ferramenta de avaliação funcional, visando contribuir para a mensuração mais cuidadosa do estado funcional do paciente por todos os profissionais da área da saúde

Conhecimentos, atitudes e práticas sobre contracepção para adolescentes

Conhecer o fenômeno da gravidez no contexto da adolescência, considerando a importância da contracepção como valioso recurso deprevenção, é uma abordagem que carece de atenção e norteia esta pesquisa, cujoobjetivo é avaliar a vivência sexual dos adolescentes e uso de métodos contraceptivos a partir do que eles conhecem sobre esses métodos e de suas atitudes frente à contracepção. Trata-se de um estudo exploratório, conduzido com estudantesdo 7º ao 9º ano de escolaridade. Os instrumentos de coleta de dados foram construídos e validados com análise das melhores condições para obtenção derespostas coerentes. As variáveis consideradas para análise foram: comunicação, atitudes, conhecimentos sobre contracepção, sexo, idade e comportamento sexual. As análises foram realizadas através dos cálculos de frequência, testes de qui-quadrado, t de student e regressão logística (considerou-se p<0,05). Os instrumentos foram validados com alfa de Cronbach de 0,70. Houve dificuldades para aobtenção de dados confiáveis nos auto-relatos dos sujeitos, verificando-se a necessidade de investigar a coerência das repostas mesmo utilizando instrumentos já validados. Dos 570 participantes, 68,8% tinha até 14 anos. Apresentaram pouco conhecimento e atitudes desfavoráveis ou ambivalentes à contracepção. Apenas 65% conversaram sobre o tema e 21,4% declararam iniciação sexual. Entre esses, a maioria (60,8%) tinha até 15 anos e 49,3% nunca usaram qualquer método contraceptivo. Não houve diferença significativa no uso da prevenção entre os que conversaram ou não sobre contracepção (p= 0,201). Os resultados apontam adolescentes expostos não só à gravidez, como à DST e alerta para a necessidade deintervenções que viabilizem uma orientação sexual capaz de promover competências para práticas sexuais mais seguras. Além disso, este estudo alerta para a dificuldade em obter dados confiáveis em pesquisas com adolescentes e evidencia a importância em se verificar a coerência das respostas mesmo utilizando instrumentos validados

Identidade e participação da comunidade rural nos processos de desenvolvimento local:desafios e competências do regulado de Nhambita-Moçambique

This thesis is defined as a reflection on the mechanisms of expression and insertion of the homo situs in the participatory governance in Mozambique. For a better understanding of this social fact, it was settled a periodization which covered the decline of colonialism at the time of the independence, which was proclaimed in June 1975, the civil war that lasted over 16 years and the period of the democratic State, further established. Therefore, we sought to understand the mechanisms and failures of the participation of the homo situs in local development projects that absorbed the needs and problems of these peasants, not mobilizing the skills and social competences of these communities. It would be essential for the homo situs a genuine democratic practice involving a political culture based on the social construction of the territories of the traditional man which was characterized by being procedural and historical, finding in participation its higher base. In this context, it would be desirable that the community development in Mozambique could contemplate and respect the choices of the homo situs. For this purpose, it would be fundamental the consistency between theory and practice, which builds and rebuilds, continually the competence of the peasants, facilitating the possibility of realization of their primordial aspirations. In the research, it became apparent that there is not a continuous process of participation of the rural communities, which appear as participants, only at the time of the implementation of the activities. Therefore, even having the participation of the communities expected by the law, with predictable moments of discussion and necessary conditions for that, the State failed to establish an ongoing process of democratic dialogue with traditional populations, as well as it failed to organize, properly, accurate informational bases to help solve the problems of rural areas. These facts have led to obstacles to the process of conquest of the human and civil rights of the traditional communities

A Fogueira do conhecimento: religação de saberes e formação

Les récits sur les expériences de vie se constituent en apprentissages signifiants dans le processus d´ auto-formation des éducateurs. La formation est un phenomène qui extrapôle l ambiance scolaire, incluant les expériences qui servent de matrice pour la construction de la connaissance au long de la vie. Dans cette perspective, «la connaissance de soi», telle quelle proposée par SOUZA, NOVOA et JOSSO, est la notion centrale au tour de laquelle se développe cette dissertation. La recherche a comme idée principale transposer pour la realité des professeurs l´exercice reflexif de son enseignement, médiant la redécouverte de ses expériences de vie, a travers des histoires de soi que, potentialisés, peuvent transformer ses pratiques dans la classe scolaire. Je prends comme point de départ mes propres expériences comme éducatrice assumant la conviction de la indissociation entre sujet et objet de la connaissance, comme propose Édgar Morin pour parler de la science de la complexité. Je fais aussi l´usage des récits de six professeurs du réseau publique de l enseigment, révélateurs de la construction de la connaissance appuyée dans la cohérence de la praxis pédagogique avec son mode de comprendre et sentir le monde. Les oeuvres «Mes Démons» d Édgar Morin, «O Tempo e Eu» de Luis da Câmara Cascudo et «O Banquete dos Deuses» de Daniel Munduruku, ont élargit le champs des récits d expériences que se constituent en matrices des processus de formation. Le travail avec les récits de formation démontrent qu´à partir de la réflection du sujet sur sa propre expérience, il est possible de se projéter des nouvelles configurations de la connaissance tenant comme base, la reliaison entre vie, idées, et pratiques pédagogiques. À partir de la métaphore du bûcher il est possible de se comprendre la force de combustion des expériences de vie dans la formation des enseignants

As condições de trabalho e a satisfação profissional: dimensões do profissionalismo docente no ensino médio

The dissertation is developed in the Research Base of Teacher Training and Professionalization of Universidade Federal do Rio Grande do Norte as a way to discuss the professionalization of High School teachers in Natal. It is a study linked to the research The context of teaching practice and professionalism: the case of high school teachers and sponsored by CNPq, with the objective of characterizing working conditions and job satisfaction as dimensions to the teacher professionalism in high schools. In this study we prioritized the focus on professionalization in national and international discussions, which combines the aspects of teaching in its historical, social, political and economical path, in order to reflect about its evolutional elements in the hierarchy of professions and establish a relation to high school teaching. To develop this relation we elaborated some questions that are considered relevant, such as: How does the high school teacher evaluate his/her working conditions to his/her professional practice? What level of satisfaction does the high school teacher have regarding his/her professional practice? What expectations does the high school teacher have in relation to his/her professional development? The answers to those questions were according to the high school teachers considerations shown in the questionnaire, which was structured with open and closed questions. These questions gave better adequacy to the teachers evaluations about their working place and the situations they experience in their working conditions, provoking job satisfaction and expectations for professional growth. The description of the teachers perception about working conditions, job satisfaction and expectation of professional development can explain the distinct factors that characterize these categories in the working context, although the conclusive results, in general, do not show a direct relationship between the categories studied. Some factors that teachers attribute as causes of bigger difficulties in working conditions and work activity itself are: working time, salary, professional status, school s infrastructure, and school s social context. These factors are similarly related to the degree of job satisfaction, without showing interference in the professional expectations

Educação - Corporeidade - Lazer: saber da experiência cultural em prelúdio

In the passage of life, the labyrinth of songs and corners are propitious ways for a better comprehension, perception and incorporation of learnings that emerge from our subjectiveness in a magic caught by senses. Eyesight, taste, hearing, touch and smell in communication with the world, put us in front of cultural diversities. The ludicity accumulated by experiences promote the flow of hilarious and concrete discoveries that express themselves in work and leisure demonstrations. Such reflections emerge indicators to the problematic construction centralized in the incorporation of cultural experience knowledge to the formation process and professional interventions in this rule and area. From this significant problematic, aiming to deepen studies, we favored leisure as field of investigative production in full expansion. This, for sure, was an exercise of qualification that guided us through meander of education and made us dip into studies about the corporeity. A research in which the scenery was painted and constructed with the complicity of the culture lived with shine, colors, rhythm and drummings of one of the most present cultural cycles: carnival. Recognized as a stimulant for beauty, participation, socialization, and helped us to enter in the essence of gestures and expressions of corporeity, to think, elaborate and socialize a critic-scientific knowledge which, appropriating from the rhythm of colors, of sounds, of tonalities, of senses and of meanings impregnated in the web of life. All these things seduced the researcher, making imagination flow amid ludic-creative dialogues with the imaginary of researchers creation and production in the rule and area of leisure, education and corporeity. Option that made us outline as objective to investigate and interpret how leisure teachers-researchers, from their studies, researches and interventions, locate and incorporate the knowledge from cultural experience to the formation process and intervention of professionals in this rule and in this area, emphasizing the contributions from this knowledge to fence and qualify this praxis. So, as living each cultural scenery, each epistemological contribution was feeding the production with images of the different versions of the Brazilian breedings, creating and raising expectations and new discoveries and newcomers. With the seriousness of a scientific study, we lived an xxiii academic experience with complex intensity, rigor and coherence, eliminating, step by step, the risks and limitations always present in a work of this magnitude. However, we weren t, even for one moment, alone. Our epistemic regard always maintained mediated by the principles of a methodological approach - the Etnomethodology, that while central guide provided us clues to unveil the lived world by our people-playful , in a universe of 15 members, that allowed themselves to comprehend, comment, analyze. This way, grasping the object in interactions arised and provoked by narrative interview, it was systematically dialected by (re) interpretation of images and formulations of people-playful, enriched by their beliefs, myths, conceptions and rituals inherent to knowledge from cultural experience, which each one attuned with Brazilian and international history, in a mixture of senses echoed from songs and tales. Inspired in drummings and percussions, clothing and choreographies of gestures and expressions, in mixtures produced in unit interactions in the multiplicity shown as necessary requests to the totality of life, with ludicity the rescue of the past, the conquest of present and the construction of future was the axle guide. This rich process of scientific creation made us realize that is possible qualify and empower the praxis in the rule and area of leisure incorporating the knowledge from cultural experience. What also becomes possible is the recuperation of objective revolutionaries and changing conditions of praxis itself with the view of strengthening and triggerment of vital elements in the rule and area of leisure. We also reaffirm that from this praxis emerge elements necessary to human formation in plenitude, by the appropriation of knowledge that guide the facing of challenges of a complex and plural world that valorize education, corporeity and leisure

É preciso estar atento: um estudo da relação entre desenvolvimento da atenção e aprendizagem

Se discute en este estudio la relación entre o desarrollo de la atención y el aprendizaje de la lengua escrita realizada con los alumnos del 5º grado de la Enseñanza Primaria, compuesta de 25 alumnos, con la edad entre 9 e 13 años, de la Escola Municipal Professor Arnaldo Monteiro Natal/RN. Para el desarrollo de este proceso investigativo, utilizamos como aporte teórico el materialismo histórico-dialéctico, pues ese método posibilita el análisis de los fenómenos y, a través de esa lógica, se revelan los elementos que dieron sustentación a la mediación pedagógica y comprensión de los fenómenos con mayor eficacia. También fueron usados los estudios de Vigotski (1991), Rubinstein (1973), Ferreira (2003), Ibiapina (2007), y otros que convergen con ese posicionamiento. Se adoptó la pesquisa colaborativa que supone la construcción de un objeto del conocimiento entre investigador y profesor y también asocia al mismo tiempo actividades de producción del conocimiento y de desenvolvimiento profesional, proponiéndose una mediación entre comunidad de investigadores y comunidad de profesores. Utilizamos como elementos metodológicos el diagnóstico de la atención, el diagnóstico de la producción escrita del texto narrativo, siguiendo las etapas elaboradas por Infante (1998), los diarios reflexivos, el planeamiento y las sesiones reflexivas (con alumnos y con los pares). Para análisis del desarrollo de la atención, utilizamos las categorías definidas por Luria (1991): volumen de la atención, estabilidad de la atención, oscilación de la atención. El análisis de la producción textual tuve como parámetros las categorías de cohesión y coherencia (COSTA VAL, 1999). Para esto, se reflexionó con ellos sobre la importancia del desenvolvimiento de la atención para aprendizajes más efectivas. Propusimos situaciones de aprendizajes que posibiliten el desarrollo de la atención de esos alumnos y el dominio de la producción textual; y se analizaron las interrelaciones entre desenvolvimiento de la atención y la producción de textos narrativos. Los resultados presentados en los textos permiten afirmar que es notoria la relación entre la atención y el aprendizaje de la escritura. Vale resaltar que la reflexión no puede tener un fin en si mismo o entonces ser usada apenas para justificar una acción, mas debe tener como objetivo mejorar la enseñaza y tornar los profesores más conscientes y, por lo tanto, más capacitados para ejercer su profesión

O Corpo do grupo corpo: os movimentos das obras Benguelê, Lecuona e Onqotô

In this research, we invite to reflection by a phenomenological gaze on the body, through the description of some works of contemporary Brazilian dance company Grupo Corpo. This Company was chosen intentionally to give us elements in their creations to interrogate the understanding of the body and sensitive. Thus, as we launch issues in this dissertation: that body dance in Grupo Corpo? And as we can see, a phenomenological approach, an understanding of the body and sensitive works in that company? Building on this, the works are to be questioned Benguelê (1998/2003), Lecuona (2004) and Onqotô (2005). It is intended, through these works, coreological approaching the discourse of philosophical discourse and give movement to phenomenological thought of Maurice Merleau-Ponty, in special the sensitive, flesh of the body, the investment in the sensory world as a merger, calling the know body and its power to take chances, to incorporate the world, language, culture, create and choose. Thus, these openings is where thought enters this research. This consistency, we used the phenomenological attitude of Maurice Merleau-Ponty as a methodological approach, since in their study the philosopher takes a look expressive on the body, forming a sensitive language that is expressed in the movements, which deepens the arguments of the Phenomenology a new arrangement for knowledge as a result of our experience in the lived world. The reflections presented here aim to take us to the amazement, the unthinking, whom many still impose epistemological challenges, including understanding the body of knowledge and sensitive
