(1835), do escritor norte-americano Edgar Allan Poe e o primeiro epis?dio (denominado ?Ber??) da micross?rie televisiva Contos do Edgar (2013), dirigida pelo cineasta brasileiro Pedro Morelli. Visando a uma delimita??o te?rica adequada dos procedimentos envolvidos nessas transposi??es da p?gina para a tela, os m?todos empregados para esta investiga??o foram os da pesquisa bibliogr?fica e os da an?lise de elementos da narrativa comuns ?s duas obras. Com o intuito de circunscrever essas reflex?es em torno da produ??o audiovisual, elegeu-se como objeto de estudo um epis?dio da miniss?rie brasileira Contos do Edgar (2013), cujo enredo ? livremente baseado no conto ?Berenice? (1835) de Edgar Allan Poe. Considerou-se a intertextualidade como elemento de liga??o entre as duas obras. O distanciamento espa?o-temporal e cultural entre ambas e a pr?pria leitura que o audiovisual fez do liter?rio foram aspectos de fundamental import?ncia para esta an?lise. Tratase de um trabalho interdisciplinar cujo foco ? o estudo da transposi??o de uma arte liter?ria para uma arte de v?deo, com aten??o ao processo intertextual envolvido na recria??o sob a forma de epis?dio televisivo. As produ??es audiovisuais s?o performances realizadas em coautoria com uma s?rie de profissionais envolvidos e que, portanto, o objeto resultante ? um constructo est?tico executado com base em diversos compartilhamentos interpretativos. Portanto, as semelhan?as e diferen?as apontadas entre os dois suportes s?o considerados elementos intertextuais. O epis?dio audiovisual analisado tamb?m apresenta elementos relacionados ao conceito de carnavaliza??o, como a profana??o, o grotesco e o rebaixamento. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Ci?ncias Humanas, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2018. / This thesis aims at contrasting theories of adaptation in order to compare the literary short story "Berenice" (1835) by the American writer Edgar Allan Poe and the first episode (titled "Ber?") of the television series Contos do Edgar (2013), directed by the Brazilian moviemaker Pedro Morelli. In order to find an appropriate theoretical procedure involved in these transpositions from the page to the screen, the methods used for this investigation were the bibliographical research and the analysis of narrative elements shared by both works. With the purpose of zeroing in on the audiovisual production, the object of study chosen was an episode of the Brazilian miniseries Contos do Edgar (2013), whose plot is freely based on the short story "Berenice" (1835) by Edgar Allan Poe. In this case, intertextuality can be regarded as an element of connection between the two works. The space-time, cultural and interpretive differences between the literary and the audiovisual were aspects of fundamental importance for this analysis. It is an interdisciplinary work, focusing on the study of the transposition of literary art into video art, and on the intertextual process involved in the recreation of the story into a television episode. The audiovisual productions are performances carried out in co-authorship with multiple professionals and, therefore, the resulting object is an aesthetic construct executed based on several interpretive exchanges. Consequently, the similarities and differences pointed out between the two media are considered intertextual elements. The audiovisual episode analyzed also presents elements related to the concept of carnivalization, such as profanation, grotesque and degradation.

In this sense, the relationship between mind and body is analyzed, presenting this phenomenon as a mental state that receives interferente from chemical reactions that occur in the human body. We also analyze how this interferes in the manifestation of this phenomenon. In addition to this aspect, it is emphasized the role that structuring and training play on the manifestation of conscious perceptual perspectives, in which they are recognized as relevant to the phenomenal adaptation. This dialectical dynamics, which takes place in between the mental events, contributes for the viability of the adaptations of perceptual perspectives, according to which human beings perceive the world and operate in it. In this work, we therefore seek to understand how the quest for survival and its maintenance, as well as the achievement of the needs raised by society and the search for knowledge, operate like demands or subjections that provide adjustments in one's conscious perceptual perspectives. / O presente trabalho investiga a ocorr?ncia do fen?meno da consci?ncia humana a partir da base biol?gica e tamb?m sob o influxo de fatores socioculturais e de componentes existenciais. Analisa-se, nesse sentido, a rela??o entre mente e corpo, apresentando esse fen?meno como um estado mental que recebe interfer?ncia das rea??es qu?micas que ocorrem na base corp?rea humana e como isso interfere na ocorr?ncia desse fen?meno. E al?m desse aspecto, ? destacado o papel que a estrutura??o e forma??o exercem na manifesta??o de perspectivas perceptivas conscientes, em que os mesmos s?o reconhecidos como relevantes para a adapta??o fenom?nica. Essa din?mica dial?tica, que ocorre entre os eventos mentais, contribui na viabiliza??o das adapta??es das perspectivas perceptivas segundo as quais seres humanos apreendem o mundo e operam nele. Procura-se, desse modo, compreender como a busca pela garantia e a manuten??o da sobreviv?ncia, o preenchimento das necessidades suscitadas pela sociedade e a procura e/ou aprofundamento de conhecimentos estariam a operar como demandas ou sujei??es que propiciariam adapta??es nas perspectivas perceptivas conscientes de uma pessoa.

Faced with these changes and complications, the patients undergo stressors capable of influencing their coping with the disease and treatment perspectives. Objective: to characterize the coping profile of patients on the waiting list for renal transplantation based on the Jalowiec Coping Scale (CJD) and to evaluate quality of life using SF-36. Method: a cross-sectional quantitative study that took place at the hemodialysis unit of Hospital S?o Lucas PUCRS, patients on the waiting list for renal transplantation, who are over 18 years of age and literate were included. Data was collected through a questionnaire with patient socio demographic information, CJD and SF36. Results: 58 patients were included, 51.7% (n = 30 males, mean age of 44.6 (? 15.2) years, 12.3% (n = 7) were above 65 years of age, more than half, 57.9% (n = 33) had elementary education. Thirty-one (54.4%) patients were married, (n = 31); 37.5% (n = 21) had one children and were of the catholic religion 62,5% (n = 35). In relation to CJD, the predominant profile was self - confident (0.455) and optimistic (0.404) 42 and 6 patients, respectively, of which 54 were focused on emotion. The dimensions evaluated with the best quality of life were: pain (67.2), social aspects (66.6) and mental health (65.4). There was a weak significant negative correlation, (r <0.333), between palliative style and vitality (r = -0.288, p = 0.028) and palliative and social aspects (r = -0.283; p = 0.031). There was a moderate negative correlation between general well being and emotive style (R = -0.424, p = 0.025) and palliative (r = -0.524, p = 0.004), as well as between Vitality and Palliative style (r = -0.530; P = 0.004). In males, there was a significant, negative moderate correlation result with a (0.300 <r?0.600) beteween Pain dimension with the Confrontive style (r = -0.413; p = 0.023) and Emotive (r = -0.370). Conclusion: the coping profile of patients on hemodialysis and in waiting list for tranplant was mostly self-confident and optimistic. The best domains in the quality of life were Pain, Social Aspects and Mental Health, and the worst physical and emotional aspects. / Introdu??o: a doen?a renal cr?nica (DRC) ? caracterizada por altera??es estruturais ou da fun??o dos rins presentes por mais de tr?s meses com implica??es para a sa?de.

Two cobalt-chromium base metal alloys were cast to prefabricated Co-Cr cast-to implant cylinders. The cylinders were placed in the abutments and mounted in epoxy resin. Three groups were formed according with base alloy. Group 1: Cylinder as manufactured (Control); Group 2: lower melting temperature alloy; Group 3: higher melting temperature alloy. The specimens were ground to their central portion longitudinally by a surface grinding machine, polished and evaluated by optical and scanning electron microscopy. The images were analyzed and the misfit areas between the cylinders and abutments were, if present, measured. For statistical evaluation of misfit areas ANOVA multivariate analysis and Tukey tests were used. Pre-fabricated cast-to cylinders which received higher melting temperature alloy showed significant differences in terms of marginal misfit. No significant differences were observed comparing the control and the lower melting temperature alloy group. Co-Cr casting alloy with a higher melting temperature cast on prefabricated Co-Cr implant cylinders might induce greater marginal misfit areas. The selected alloy for compound casting must not exceed the melting temperature of prefabricated implant cylinder base as recommended by manufactures. / O objetivo desde estudo foi analisar se os diferentes pontos de fus?o de ligas de cobalto-cromo (Co-Cr) para sobrefundi??o podem influenciar na adapta??o marginal de cilindros pr?-fabricados para pr?tese implantossuportada. Duas ligas met?licas de Co-Cr com pontos de fus?o distintos indicados pra t?cnica de sobrefundi??o foram fundidas aos cilindros pr?-fabricados com base de Co-Cr. As amostras foram confeccionadas, fixando os cilindros aos pilares e embutidas em resina ep?xi, formando tr?s grupos de acordo com a liga utilizada. Grupo 1: controle (cilindros de f?brica); Grupo 2: liga de Co-Cr com menor ponto de fus?o (LMT); Grupo 3: liga de Co-Cr com maior ponto de fus?o (HMT). As amostras foram seccionadas longitudinalmente na por??o central do conjunto por uma m?quina de precis?o, polidas e encaminhadas para avalia??o por microscopia eletr?nica de varredura ?ptica. As imagens foram analisadas e verificadas a presen?a de desadapta??es. Cada ?rea de desadapta??o entre cilindro e pilar foram medidas. Os resultados demonstraram signific?ncia (p<0.005) para o grupo em que os cilindros pr?-fabricados foram sobrefundidos com a liga de maior ponto de fus?o apresentando ?reas de desadapta??o marginal ao pilar. O grupo HMT demonstrou valores m?dios para ?rea de 2,489 ?m2 (?1,073), o grupo LMT de 1,536 ?m2 (? 0,375) e enquanto o grupo controle de 1,272 ?m2 (? 0,577). Para as medidas de estabilidade dimensional n?o foram observadas diferen?as estat?sticas (p>0.005) entre os grupos experimentais. Contudo, indica-se que para sobrefundi??o de cilindros pr?-fabricados a liga met?lica utilizada n?o deve possuir ponto de fus?o acima do preconizado pelo fabricante do cilindro.

Thus, this thesis sought to understand how the process of identification come about between the player and her character/avatar in the simulated environment of the virtual game through the conditions of (im)possibility and of decidability according to the ethics of Jacque Derrida. Therefore, these processes were analyzed taking into consideration the relations established between the player and the game world through immersion, interaction, and agency; they may result in the construction of a fictional and virtual identity. The Elder Scrolls V: Skyrim and Journey were the analyzed games, because their structure for customization are opposed, since this possibility offers to the gamer the exercise of creating her own character. The bibliography was mainly from Theory of Literature, Game Studies and Philosophy. In addition to the analysis of the games, this thesis evaluated, through a survey, the habits of users and video game genres. The analyses of the games were made through the gameplays of the author of this thesis and from the evaluation of the interactions of players using their gameplays videos available on the internet video channels. The games analyzed allowed to list characteristics that enable the development of fictional and virtual identities, and also narrative, in the game world. The conditions of decidability had two poles: there are enough interactivity and possibilities of choices in The Elder Scrolls V: Skyrim, while in Journey this interaction is low; the conditions of (im)possibility are still well calculated by the gaming systems, then, it is for the subject player to perform singular events in her interaction with the game world. Therefore, the singular events decided and performed by each gamer are the ones that implicate in processess of identification built narratively in the games. ?Final? thoughts on the issue are for the future and for further research addressing the cultural relations between players and video games. / Os jogos de videogame ocupam, atualmente, um lugar de destaque entre os produtos culturais populares e o n?mero de pessoas que jogam tem crescido bastante nas ?ltimas d?cadas. Diante disso, esta tese buscou compreender como se d?o os processos de identifica??o entre a pessoa jogadora e sua personagem/avatar no ambiente simulado do jogo virtual por meio das condi??es de (im)possibilidade e de decidibilidade conforme a ?tica derridiana. Para tanto, esses processos foram analisados a partir das rela??es que a jogadora estabelece com o mundo do jogo pela imers?o, intera??o e ag?ncia, podendo culminar na constru??o de uma identidade virtual ficcional. Os jogos analisados foram The Elder Scrolls V: Skyrim e Journey, pois se op?em em sua estrutura customiz?vel, sendo que esta funcuinalidade j? oferece ? jogadora a cria??o de uma personagem sua (funcionando como um primeiro pilar de identifica??o). Foi utilizada bibliografia variada, principalmente da Teoria da Literatura, dos Game Studies e da Filosofia. Al?m de analisar os jogos, esta tese avaliou, atrav?s de um levantamento, os h?bitos de usu?rios e de usu?rias e de g?neros de videogames. As an?lises dos jogos foram realizadas atrav?s dos gameplays da autora desta tese e da avalia??o das intera??es de jogadores e de jogadoras diversas utilizando v?deos de gameplays disponibilizados em canais de v?deo da internet. Os jogos analisados permitiram elencar caracter?sticas que possibilitam a elabora??o de identidades virtuais ficcionais, e tamb?m narrativas, no mundo do jogo. As condi??es de decidibilidade apresentaram dois p?los: h? bastante interatividade e possibilidades de escolhas em The Elder Scrolls V: Skyrim, enquanto que em Journey essa intera??o ? baixa; as condi??es de (im)possibilidade ainda s?o bem determinadas pelos sistemas dos jogos, cabendo ? jogadora realizar eventos singulares na sua intera??o com o mundo do jogo. Nesse sentido, s?o os eventos singulares decididos e realizados por cada jogadora que implicam em processos identit?rios constru?dos narrativamente nos jogos. Pensamentos ?finais? sobre a quest?o toda esperam a continuidade de pesquisas que abordem as rela??es culturais entre as pessoas e os videogames.

Entretanto, a cultura do Bring Your Own Device dificulta a no??o de dom?nio seguro, contribuindo para a cria??o de vetores de ataques dentro do per?metro seguro. Os sistemas de firewall distribu?do surgiram com a proposta de prover prote??o de hosts individuais a ataques originados na pr?pria rede interna. Em tais sistemas, as regras s?o criadas de modo centralizado e ent?o distribu?das e aplicadas em todos os servidores que comp?em o firewall, restringindo quais servi?os devem estar dispon?veis. N?o obstante, vulnerabilidades em software podem tornar os servi?os de rede vulner?veis a ataques, uma vez que firewalls usualmente n?o analisam os protocolos de aplica??o. Neste sentido, a partir da descoberta da vulnerabilidade at? a publica??o e aplica??o dos patches de corre??o existe uma janela de exposi??o que deve ser reduzida. Dado este cen?rio, o presente trabalho apresenta uma proposta de um sistema de firewall distribu?do auto-adaptativo. Esta proposta ? baseada no monitoramento de hosts e no uso de um sistema de avalia??o de vulnerabilidades para detectar servi?os vulner?veis, integrado com componentes capazes de decidir e aplicar regras de firewall nos hosts afetados. Desse modo, esta abordagem ? capaz de responder a vulnerabilidades descobertas nesses hosts, contribuindo para mitigar o risco de explora??o da vulnerabilidade. Nosso sistema foi avaliado no contexto de um estudo de caso que simula um ambiente de rede corporativa, onde os resultados alcan?ados demonstram sua viabilidade. / The border firewall play a fundamental role for corporate network security, acting as the first defense barrier delimiting a secure perimeter. However, the culture of Bring Your Own Device weakens the notion of secure domain, contributing to the creation of attack vectors inside the secure perimeter. Distributed firewall systems emerged with the proposal of protecting individual hosts against attacks originating from inside the network. In such systems, firewall rules are created centrally, then distributed and enforced on all servers that compose the firewall, restricting which services should be available. Meanwhile, software vulnerabilities can make network services vulnerable to attacks, since firewalls usually do not scan application protocols. In this sense, from the discovery of a vulnerability until the publication and application of patches there is an exposure window that must be reduced. Given this scenario, the present work presents a proposal of a self-adaptive distributed firewall system. This proposal is based on monitoring hosts and using a vulnerability assessment system to detect vulnerable services, integrated with components capable of deciding and applying firewall rules on affected hosts. In this way, our approach is able to respond to vulnerabilities discovered in these hosts, helping to mitigate the risk of exploiting the vulnerability. Our system was evaluated in the context of a case study that simulates a corporate network environment, where the results achieved demonstrate its viability.

O exerc?cio f?sico melhora as defesas antioxidantes, contudo em altas cargas e em baixas concentra??es de estr?geno possui efeito aditivo ao dano oxidativo. O ?cido &#945;-lip?ico possui uma ampla gama de a??o antioxidante e poderia contribuir para diminui??o do dano nestas condi??es. Objetivo: O objetivo deste estudo ? caracterizar a a??o do ?cido &#945;-lip?ico sobre a adapta??o antioxidante e fun??es reprodutivas de ratas submetidas a nata??o moderada. Material e m?todos: Os animais foram submetidos a nata??o di?ria (1 hora) e sacrificados ap?s 30, 60 e 90 dias. Os animais foram divididos em controles sedent?rios e exercitados; suplementados (?cido &#945;-lip?ico 100mg/Kg/dia) sedent?rios e exercitados e animais ovariectomizados e suplementados com ?cido lip?ico. Avaliou-se diariamente o ciclo estral e os seguintes marcadores de estresse oxidativos foram mensurados em f?gado e sangue: atividade enzim?tica da SOD, GPx e CAT, al?m do SRAT e GSH. Resultados: O protocolo de exerc?cio aumentou a dura??o do ciclo estral no grupo controle exercitado, sobretudo na fase diestral. Neste mesmo grupo, houve diminui??o da lipoperoxida??o com melhora da atividade antioxidante da SOD e GPx. O grupo exercitado e suplementado n?o apresentou altera??o na dura??o do ciclo estral e manteve os benef?cios sobre o sistema antioxidante antes observado nos animais exercitados. A suplementa??o antioxidante juntamente com a nata??o em per?odos superiores a 30 dias, diminuiu o processo de adapta??o antioxidante quando comparado aos animais somente exercitados. Nos animais ovariectomizados, o exerc?cio e a suplementa??o com ?cido lip?ico n?o promoveu adapta??o antioxidante ao contr?rio dos demais grupos. Conclus?o: O aumento na dura??o do ciclo estral e a melhora nos marcadores de estresse oxidativo seriam uma resposta adaptativa frente ao exerc?cio moderado. O ?cido lip?ico impediu a altera??o no ciclo induzida pelo exerc?cio, mas preservou a melhoria no sistema antioxidante. A deple??o estrog?nica provocada pela ovariectomia eleva o potencial de dano oxidativo gerado pelo exerc?cio. A a??o antioxidante do LA na presen?a de estr?geno diminuiu excessivamente o dano oxidativo, comprometendo a adapta??o antioxidante a nata??o. Nos animais ovariectomizados, contudo, o AL promoveu adapta??o antioxidante ao exerc?cio

The effects of the semiarid climate, together with other biophysics, social and political-economic factors, impair the agricultural production, generating a situation of food insecurity and poverty in the rural areas. With the occurrence of climate change, natural resources of the semiarid regions can became scarcer, what would directly affect the agricultural production and those who depend on it. Therefore, the present study sought to study one of the most susceptible areas to the effects of the semiarid climate and desertification of Rio Grande do Norte, the potiguar s Serido. The study aimed to analyze the socioeconomic and environmental factors that put farmers in a position of vulnerability to the effects of climate; assess their perceptions about climate variations that have already occurred and their knowledge about climate change and global warming, also to identify which adaptation strategies to climate they have adopted at the rural establishment. The survey was conducted in 29 communities of four counties of the potiguar s Serido Caico, Parelhas, Lagoa Nova and Acari. Semi-structured interviews were conducted with local leaders and 241 questionnaires were applied with the family farmers. It was found that in addition to environmental factors such as the scarcity of water resources and climatic conditions, other factors such as the environmental degradation, the small size of the properties, the lack of technical assistance and financial resources and also the low education levels reduce the resilience capacity of family farming to the effects of the Semiarid climate. With the occurrence of climate change, the challenges for family farming at Serido will intensify. If farmers cannot adapt, the impacts may preclude this category of agricultural production causing serious harm to food security and further increasing the vulnerability situation of these populations. Although the farmers perceived changes in climate, the lack resources and information appears as the main reasons preventing the adoption of adaptation strategies. The lack of knowledge about climate change and global warming and the impacts that these phenomena may cause are also limiting factors for adaptation. It is therefore essential to identify the factors that influence the adoption of adaptation strategies, and seek alternatives to living with the semiarid that can strengthen the resilience of family farming and social reproduction that allow agricultural segment, even in a climate change scenario / Nas regi?es semi?ridas dos pa?ses em desenvolvimento as popula??es rurais sempre estiveram vulner?veis ?s varia??es clim?ticas e suas consequ?ncias. Os efeitos do clima Semi?rido, aliados ? outros fatores biof?sicos, sociais, pol?ticos e econ?micos, prejudicam a produ??o agr?cola, gerando uma situa??o de inseguran?a alimentar e pobreza no meio rural. Com o advento das mudan?as clim?ticas, os recursos naturais das regi?es semi?ridas poder?o se tornar ainda mais escassos, o que afetaria diretamente a produ??o agr?cola e os que dela dependem. Nesse contexto, a presente pesquisa buscou estudar uma das ?reas mais suscept?veis aos efeitos do clima semi?rido e da desertifica??o do Rio Grande do Norte, o Serid? potiguar. O estudo teve como objetivo analisar os fatores socioecon?micos e ambientais que colocam os agricultores familiares numa situa??o de vulnerabilidade aos efeitos do clima; avaliar suas percep??es sobre as varia??es clim?ticas j? ocorridas e seus conhecimentos sobre mudan?as clim?ticas e aquecimento global, al?m de verificar quais as estrat?gias de adapta??o ao clima foram realizadas no ?mbito do estabelecimento rural. A pesquisa foi realizada em 29 comunidades de quatro munic?pios do Serid? potiguar Caic?, Parelhas, Lagoa Nova e Acari. Foram realizadas entrevistas semiestruturadas com lideran?as locais e aplicados 241 question?rios com os agricultores familiares. Verificou-se que al?m dos fatores ambientais como a escassez dos recursos h?dricos e as condi??es clim?ticas outros fatores como degrada??o ambiental o tamanho reduzido das propriedades, a falta de assist?ncia t?cnica e de recursos financeiros, al?m do baixo n?vel de escolaridade dos agricultores reduzem a capacidade de resili?ncia da agricultura familiar aos efeitos do clima Semi?rido. Com a ocorr?ncia das mudan?as clim?ticas, os desafios para a agricultura familiar do Serid? potiguar ir?o se intensificar e, caso os agricultores n?o consigam se adaptar, os impactos poder?o impossibilitar a produ??o agr?cola dessa categoria, causando graves preju?zos para a seguran?a alimentar e aumentando ainda mais a situa??o de vulnerabilidade dessas popula??es. Apesar de perceberem as altera??es no clima, a limita??o de recursos financeiros e a falta de informa??es aparecem como principais impedimentos ? ado??o de estrat?gias de adapta??o. A falta de conhecimento sobre as mudan?as clim?ticas, aquecimento global e sobre os impactos que esses fen?menos podem causar tamb?m s?o fatores limitantes ? adapta??o. Torna-se assim, essencial identificar os fatores que influenciam a ado??o de estrat?gias de adapta??o, al?m de buscar alternativas para a conviv?ncia com o semi?rido que possam fortalecer a resili?ncia da agricultura familiar e permitir reprodu??o social desse segmento agr?cola, mesmo num cen?rio de mudan?as clim?ticas

Objetiva-se validar o Nurse Competence Scale para a l?ngua portuguesa do Brasil. A escala avalia a compet?ncia do enfermeiro, constitu?da de 73 itens, distribu?dos em 7 categorias, demonstra ser sens?vel na diferencia??o dos n?veis de compet?ncia, incluindo a fase de transi??o de estudante de enfermagem para a fase de enfermeiro. Estudo metodol?gico desenvolvido entre setembro de 2016 a junho de 2017, ap?s a autoriza??o da autora principal do instrumento e a aprova??o pelo Comit? de ?tica em Pesquisa da Universidade Federal do Rio Grande do Norte, sob o parecer n? 1.766.255. Conduziu-se as validades de conte?do e de construto (dimensionalidade), e an?lise da confiabilidade (teste-reteste e consist?ncia interna), em duas etapas: a primeira, correspondeu ? adapta??o cultural do instrumento, e a segunda, ? verifica??o das qualidades psicom?tricas da escala adaptada. Participaram do estudo, 141 concluintes do curso de Gradua??o em Enfermagem de Institui??es P?blicas de Ensino Superior do estado do Rio Grande do Norte. O ?ndice de Validade de Conte?do foi de 0,99, e o coeficiente Kappa foi considerado quase perfeito. Dos 73 itens da escala, apenas 13 apresentaram diferen?a significativa no teste de compara??o de m?dias durante o teste-reteste (n = 30) para o n?vel de compet?ncia. O alfa de Cronbach total nessa etapa foi 0,97, e variou de 0,75 a 0,92, entre as categorias. E a segunda, participaram 111 concluintes, com m?dia de idade de 24,2 (DP = 3,5); sendo 84,7% do g?nero feminino e 95,5% sem experi?ncia anterior na ?rea de Enfermagem. O instrumento foi considerado de f?cil preenchimento, com tempo m?dio de aplica??o de 15 minutos, em ambas as etapas. Os alunos se autoavaliaram como tendo um bom n?vel de compet?ncia (m?dia geral = 73,9), com uma m?dia de uso efetivo dos itens na pr?tica, igual a 2, o que corresponde a ?usado ocasionalmente?. O n?vel de compet?ncia foi maior para a Fun??o de Apoio (80,5), e menor, para as Interven??es Terap?uticas (67,8). A an?lise de correla??o entre os itens da escala, apresentou-se de moderada a forte, com destaque para a correla??o entre as Interven??es Terap?uticas com as Fun??es Educativas (0,71), com as Fun??es Diagn?sticas (0,74) e com as Fun??es Gerenciais (0,78). A an?lise fatorial confirmat?ria demonstrou que o instrumento adaptado est? razoavelmente ajustado ? estrutura original proposta pela autora principal. Nessa etapa, o coeficiente alfa de Cronbach foi superior a 0,70, com exce??o da categoria Fun??o de Apoio (0,65). O processo de valida??o da escala foi alcan?ado, e a vers?o brasileira, denominada Escala de Compet?ncia do Enfermeiro mostrou-se v?lida e confi?vel para a amostra estudada. Acredita-se que a escala pode ser utilizada como ferramenta de avalia??o das compet?ncias de graduandos de Enfermagem, apesar da regionalidade dos dados. Recomenda-se a realiza??o de novos estudos, que permitam uma avalia??o mais profunda das qualidades psicom?tricas e compara??es entre resultados de pesquisas sobre o uso da vers?o brasileira do Nurse Competence Scale. / Although it is common to have some doubts about the skills of the recent graduate, the process of nurses? training requires the development of the skills necessary for their performance. The objective of this study is to validate the Nurse Competence Scale to Brazilian Portuguese. This scale evaluates nurses? competence, consisting of 73 items, distributed in 7 categories, showing to be sensitive in the differentiation of competence levels, including the transition phase from nursing student to the nurse phase. This is a methodological study developed between September 2016 and June 2017, after the authorization of the lead author of the instrument and approval by the Research Ethics Committee of the Federal University of Rio Grande do Norte, under opinion n? 1,766,255. The content and construct validities (dimensionality), the reliability analysis (test-retest and internal consistency) were conducted in two stages. The first stage corresponded to the cultural adaptation of the instrument, and the second stage was the verification of the psychometric qualities of the adapted scale. There were 141 undergraduate students enrolled in the Undergraduate Nursing course of Public Institutions of Higher Education in the state of Rio Grande do Norte participated in the study. The Content Validity Index was 0.99, and the Kappa coefficient was considered almost perfect. Only 13 of the 73 items on the scale presented a significant difference in the test of comparison of means during the test-retest (n = 30) for the competence level. Cronbach's total alpha at this stage was 0.97 and ranged from 0.75 to 0.92 in the categories. In the second stage, there were 111 participants participating, with a mean age of 24.2 (SD = 3.5); 84.7% were female and 95.5% had no previous experience in the Nursing area. The instrument was considered easy to fill up, with an average application time of 15 minutes, in both stages. The self-evaluation of the students was as having a good level of competence (average of 73.9), with an average of effective use of the items in practice, equal to 2, corresponding to ?used occasionally?. The level of competence was higher for the Supporting Function (80.5), and lower for the Therapeutic Interventions (67.8). The analysis of correlation between the items of the scale was moderate to strong, especially the correlation between Therapeutic Interventions with Educational Functions (0.71), Diagnostic Functions (0.74) and Functions Management (0.78). The confirmatory factor analysis has shown that the adapted instrument is reasonably adjusted to the original structure proposed by the lead author. At this stage, Cronbach's alpha coefficient was higher than 0.70, except for the Support Function category (0.65). The scale validation process was reached, and the Brazilian version, called Escala de Compet?ncia do Enfermeiro was valid and reliable for the sample studied. It is believed that this scale can be used as a tool to evaluate the skills of nursing undergraduates, despite the regionality of the data. Further studies are recommended to allow a more thorough evaluation of the psychometric qualities and comparisons between research results using the Nurse Competence Scale Brazilian version.
