Conhecimento dos enfermeiros do Hospital Universitário Onofre Lopes sobre sistematização da assistência de Enfermagem

Nursing as a profession goes in search on quality of their care through new frameworks, trying to break postures of the health care system so fragmented in the care. To change professional practices, it is necessary to build their own knowledge grounded on Nursing Care System. The aim of this study was to analyze the influence of nurses' knowledge on care systematization in nursing in the University Hospital Natal-RN. It is an analytical descriptive study carried out at the Onofre Lopes University Hospital (HUOL), Natal-RN, 2010, the sample was composed of 40 active nurses working in hospitalization units of the hospital, the inclusion criteria were being in the monthly scale sector and agree to participate in the study. The non-participant observation and another interview were used for collecting data, statistical analysis was descriptive and inferential with reliability test, Pearson test, chi-square and Fischer, the variables that correlated were analyzed in a model Multiple logistic , calculating odds ratio. The results were: predominance of female professionals (90%), predominantly in the age range 39-46 years (37.5%), nurses who have the undergraduate degree at the Federal University of Rio Grande do Norte (80%), and who have expertise training as a minimal degree (62.5%). Among the surveyed, the knowledge showed significance with the graduation time (p = 0.018) and time working in HUOL (p = 0.036). The majority of the professionals surveyed do not know which organ is responsible for the SAE legislation (52.5%), aware of the steps needed to build the nursing diagnosis (92.5%), understand the characteristics of nursing planning (90% ). However the same professionals do not perform physical examination in patients (50.0%) did not classify the clinical findings (68.4%), and identify the problems encountered as a classification (13.2%). The planning of nursing care is carried out by verbal order of nurses (82.5%), 41% of the professionals assess only the intervention stage, in other words, the actions taken. Regarding the practical application of nursing records 53% of nurses do not realize records, 30.8% is incomplete, the other held notes (p = 0.003). The nurses know the nursing process (90% of appropriate responses), despite the actions defined by the theory are not applied in practice. Investigators believe the condition of the hospital teacher (22.5%) could positively affect the implementation of the SAE associated with the interest of professionals (20%). Of the respondents, 17.5% accept as truth the lack of facilities to assist the SAE implementation in the hospital. It was concluded that nurses know the theory that underlies the SAE and the nursing process, but do not develop the service know as well, there is need for action to boost the SAE implementation as practice of nurses in the hospital investigated

Avaliação de economias de escala e escopo no desempenho de equipes de serviços aplicando Análise de Envoltória de Dados DEA: um estudo em Empresa de Telecomunicações no Brasil

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate economies of scale and economies of scope in the performance of service teams involved with installation of data communication circuits, based on the study of a major telecommunication company in Brazil. Data was collected from the company s Operational Performance Division. Initial analysis of a data set, including nineteen installation teams, was performed considering input oriented methods. Subsequently, the need for restrictions on weights is analyzed using the Assurance Region method, checking for the existence of zero-valued weights. The resulting returns to scale are then verified. Further analyses using the Assurance Region Constant (AR-I-C) and Variable (AR-I-V) models verify the existence of variable, rather than constant, returns to scale. Therefore, all of the final comparisons use scores obtained through the AR-I-V model. In sequence, we verify if the system has economies of scope by analyzing the behavior of the scores in terms of individual or multiple outputs. Finally, conventional results, used by the company in study to evaluate team performance, are compared to those generated using the DEA methodology. The results presented here show that DEA is a useful methodology for assessing team performance and that it may contribute to improvements on the quality of the goal setting procedure.

Análise de retorno de escala e tamanho do mercado no desempenho de equipes de vendas aplicando análise de envoltória de dados DEA: um estudo em empresa de Telecomunicações no Brasil

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate the performance of sales teams, based on a study of their coverage areas. Data was collected from the company contracted to distribute the products in the state of Ceará. Analyses of thirteen sales coverage areas were performed considering first the output-oriented constant return to scale method (CCR-O), then this method with assurance region (AR-O-C) and finally the method of variable returns to scale with assurance region (AR-O-V). The method used in the first approach is shown to be inappropriate for this study, since it inconveniently generates zero-valued weights, allowing that an area under evaluation obtain the maximal score by not producing. Using weight restrictions, through the assurance region methods AR-O-C and AR-O-V, decreasing returns to scale are identified, meaning that the improvement in performance is not proportional to the size of the areas being analyzed. Observing data generated by the analysis, a study is carried out, aiming to design improvement goals for the inefficient areas. Complementing this study, GDP data for each area was compared with scores obtained using AR-O-V analysis. The results presented in this work show that DEA is a useful methodology for assessing sales team performance and that it may contribute to improvements on the quality of the management process.

Aplicando análise de envoltória de dados -DEA à avaliação de desempenho acadêmico: um estudo em programas de pós-graduação em engenharia mecânica e produção no Brasil

This Master of Science Thesis deals with applying DEA (Data Envelopment Analysis) to the academic performance evaluation of graduate programs in Brazil, exploring it on a Mechanical and Production Engineering Program 2001-2003 data. The data used is that of the national assessment carried by CAPES, the governmental body in charge for graduate program assessment and certification. It is used the CCR output oriented DEA model, the CCR-Output with Assurance Region, and Window Analysis. The main findings are first that the CCR has the concerning problem of zero values of weights of outputs that is not appropriate in a sense that a graduate program has the higher efficiency score zeroing some output (e.g., number of academic papers published). Secondly, the Assurance Region method proved useful. Third, the Window Analysis also gave some light to the consistency of the performance in the time frame analysed. Also, the analysis results in the understanding that the Mechanics and Production Engineering should not be assessed jointly like currently applied by CAPES and rather should be assessed in its own field separately. Finally, the result of the DEA analysis showed some serious inconsistencies with the CAPES method. Graduate programs considered excellent has got low performance score and vice versa. This Thesis provides a strong argument in order to use DEA at least as a complimentary methodology for graduate program performance evaluation in Brazil

Uma ferramenta para Análise Multiresolução de dados não regularmente amostrados

Digital signal processing (DSP) aims to extract specific information from digital signals. Digital signals are, by definition, physical quantities represented by a sequence of discrete values and from these sequences it is possible to extract and analyze the desired information. The unevenly sampled data can not be properly analyzed using standard techniques of digital signal processing. This work aimed to adapt a technique of DSP, the multiresolution analysis, to analyze unevenly smapled data, to aid the studies in the CoRoT laboratory at UFRN. The process is based on re-indexing the wavelet transform to handle unevenly sampled data properly. The was efective presenting satisfactory results

Estudo da secagem do pedúnculo do caju em sistemas convencional e solar: modelagem e simulação do processo

This work aims to study the drying of cashew-nut pulp with different lay-out of dryers using conventional and solar energy. It concerns with the use of exceeding of the regional raw material and the suitable knowledge for the applicability of the drying systems as pathway for food conservation. Besides, it used renewable sources as solar energy to dry these agroindustrial products. Runs were carried out using a conventional tray-dryer with temperature, air velocity control and cashew slice thickness of 55°C, 65°C, 75°C; 3.0; 4.5, 6.0 m s-1; 1.0; 1.5 and 2.0 cm, respectively, in order to compare the studied systems. To evaluate the conventional tray-dryer, it was used a diffusional model of 2nd Fick´s law, where the drying curves were quite well fitted to an infinite flat plate design. For the drying runs where the room temperature had no control, it was developed a phenomenological-mathematical model for the solar dryer with indirect radiation under natural and forced convection based on material and energy balances of the system. Besides, it was carried out assays in the in natura as well as dehydrated, statistic analysis of the experimental drying data, sensorial analysis of the final dry product and a simplified economical analysis of the systems studied

As construções adverbiais em mente: análise funcionalista e implicações para o ensino de língua materna

This research aims at investigating the constructions with adverbials in ly, based on the view of contemporaneous linguistic functionalism, such as proposed by Givón, Hopper, Thompson, Traugott, Furtado da Cunha, as well as the cognitivist notion of language, through construction grammar support upon the patterns of Goldberg and the prototypes theory. The cognitive functional approach adopted here considers the change as a proper and inherent phenomenon of language and understands the linguistic phenomenon as resulting from effective use of language. Another aspect to be considered to the realization of this study is the fact that the formation adjective + ly is a word construction mechanism really productive, which generates interests on linguistic description. In a particular way, our leading objective is to exam the constructions with adverbials in ly in the context of language in use, in its oral and written forms, looking for to apprehend the meaning multiple manifestations forged in the use. Bearing this in mind, we worked with data from the Corpus Discurso & Gramática (Natal). There are, in the data, adverbs ended in ly that take the signification of mode, as foreseen in traditional models, but there are also other significations, for instance, the modalizador in its different manifestations. The results show that this adverb is a linguistic mark that carries in its constitution the multissêmico and multifunctional character, which interferes extremely in the ordination of this category, assuming a position sometimes pre-verbal, sometimes post-verbal. Other aspect observed refers to the relationship between the adverb and the verb, with emphasis on the compatibility or restriction between them, option which is related to the semantic aspect. The data in analysis legitimate the use in different constructions with adverb ended in ly in various genres, as follows: personal experience narrative, retold narrative, local description, proceeding account, opinion account, both in oral as in written language

Caminhos para a universalização dos serviços de água e esgotos no Brasil: a atuação das entidades reguladoras para indução da eficiência dos prestadores de serviços

The deficit of water and sewerage services is a historic problem in Brazil. The introduction of a new regulatory framework, in 2007, presented ways intending to overcome these deficits, among them, the providers efficiency improvement. This thesis aims to analyze the regulators performance regarding its ability to induce the efficiency of the Brazilian water and sewerage services providers. To this end, an analytical approach based on a sequential explanatory strategy was used, and it consists of three steps. In the first step, the Data Envelopment Analysis ( DEA ) was used to measure the providers efficiency in 2006 and 2011. The results show that the average efficiency may be considered high; however significant inefficiencies among the 29 analyzed providers were detected. The ones in the Southeast region showed better performance level and Northeast had the lowest. The local and the private providers were more efficient on average. In 2006 and 2011 the average performance was higher among non-regulated providers. In 2006 the group regulated by local agencies had the best average performance, in 2011, the best performance was the group regulated by the consortium agencies. To analyse the second step was used the Malmquist Index, it pointed that the productivity between 2006 and 2011 dropped. The analysis through decomposing Malmquist Index showed a shift of technical efficiency frontier to a lower level, however was detected a small provider s advance towards the frontier. Only the Midwest region recorded progress in overall productivity. The deterioration in the total factor productivity was higher among regional providers but the local ones and the private agencies moved quickly to the frontier level. The providers regulated from 2007 showed less decrease on the total productivity and the results of the catch up effect were more meaningful. In the last step, the regulators standardization activity analyses noted that there are agencies that had not issued rules until 2011. The most standards topics discussed in the issued rules were the tariff adjustments and the setting of general conditions for the provision and use of services; in another hand, the least covered topics were new technologies incentive and the introduction of efficiency-inducing regulatory mechanisms and productivity gains for price reviews. Regulators created from 2007 were more active proportionately. Even with the advent of the regulatory framework and the creation of new regulatory bodies, the evidence points to a reality in which the actions of these agencies have not been ensuring that providers of water and sewage, regulated by them, has achieved better performance. The non- achievement of regulatory goals can be explained by the incipient level of performance of the Brazilian regulatory authorities, which should be strengthened because of its potential contribution to the Brazilian basic sanitation department

Determinação de Ba, Cd, Cr, Cu, Ni, Pb, Sn e Zn em Tainha (Mugil brasiliensis) nos estuários potiguares

Heavy metals can cause problems of human poisoning by ingestion of contaminated food, and the environment, a negative impact on the aquatic fauna and flora. And for the presence of these metals have been used for aquatic animals biomonitoramento environment. This research was done in order to assess the environmental impact of industrial and domestic sewage dumped in estuaries potiguares, from measures of heavy metals in mullet. The methods used for these determinations are those in the literature for analysis of food and water. Collections were 20 samples of mullet in several municipality of the state of Rio Grande do Norte, from the estuaries potiguares. Were analyzed the content of humidity, ash and heavy metals. The data were subjected to two methods of exploratory analysis: analysis of the main components (PCA), which provided a multivariate interpretation, showing that the samples are grouped according to similarities in the levels of metals and analysis of hierarchical groupings (HCA), producing similar results. These tests have proved useful for the treatment of the data producing information that would hardly viewed directly in the matrix of data. The analysis of the results shows the high levels of metallic species in samples Mugil brasiliensis collected in Estuaries /Potengi, Piranhas/Açu, Guaraíra / Papeba / Arês and Curimataú

Estruturas tectônicas cenozóicas na porção leste da Bacia Potiguar - RN

This thesis encompasses the integration of geological, geophysical, and seismological data in the east part of the Potiguar basin, northeastern Brazil. The northeastern region is located in South American passive margin, which exhibits important areas that present neotectonic activity. The definition of the chronology of events, geometry of structures generated by these events, and definition of which structures have been reactivated is a necessary task in the region. The aims of this thesis are the following: (1) to identify the geometry and kinematics of neotectonic faults in the east part of the Potiguar basin; (2) to date the tectonic events related to these structures and related them to paleoseismicity in the region; (3) to present evolutional models that could explain evolution of Neogene structures; (4) and to investigate the origin of the reactivation process, mainly the type of related structure associated with faulting. The main type of data used comprised structural field data, well and resistivity data, remote sensing imagery, chronology of sediments, morphotectonic analysis, x-ray analysis, seismological and aeromagnetic data. Paleostress analysis indicates that at least two tectonic stress fields occurred in the study area: NSoriented compression and EW-oriented extension from the late Campanian to the early Miocene and EW-oriented compression and NS-oriented extension from the early Miocene to the Holocene. These stress fields reactivated NE-SW- and NW-SE-trending faults. Both set of faults exhibit right-lateral strike-slip kinematics, associated with a minor normal component. It was possible to determine the en echelon geometry of the Samambaia fault, which is ~63 km long, 13 km deep, presents NE-SW trend and strong dip to NW. Sedimentfilled faults in granite rocks yielded Optically Stimulated Luminescence (OSL) and Single-Aliquot Regeneration (SAR) ages at 8.000 - 9.000, 11.000 - 15.000, 16.000 - 24.000, 37.000 - 45.500, 53.609 - 67.959 e 83.000 - 84.000 yr BP. The analysis of the ductile fabric in the João Câmara area indicate that the regional foliation is NE-SW-oriented (032o - 042o), which coincides with the orientation of the epicenters and Si-rich veins. The collective evidence points to reactivation of preexisting structures. Paleoseismological data suggest paleoseismic activity much higher than the one indicated by the short historical and instrumental record

Os farofeiros em excursão nas lagoas de Arituba, Boágua e Carcará (Nísia Floresta/RN): análise de uma outra face do turismo potiguar

This thesis analyzes another side of Potiguar tourism , the unplanned side, neglected and kept out of touristic activities: excursionism, a leisure practice enjoyed by tourists with low consumer power, and who are commonly referred by the pejorative term farofeiros (picnic lovers). The geographic research sites considered for this study include Arituba, Boágua and Carcará lakes in Nísia Florest, Rio Grande do Norte, where on Sundays and holidays the arrival of hundreds of excursionists, from around the metropolitan region of Natal, from surrounding municipalities, and neighboring States, such as Paraíba and Pernambuco, can be observed. The objective of this study is to analyze the appropriation of the physical site by the practice of excursionism, focusing on its relation to other social agents that also appropriate a designated touristic area. The theoretical discussion considers the use of the space by the touristic leisure practice and the appropriation by distinct social agents, using categories of analysis, such as, production of the space, territory and leisure. The field work was completed with interviews and questionnaires administered to excursionists, excursion organizers, local merchants, representatives of the public setor from the municipalities, and professional dune buggy drivers; besides this, photos, informal dialogue and field observations were important methodological instruments used. From the data, statistical analysis and the development of thematic maps demonstrating the established flux between excursionists and the segregated activity were done. With this research, one can affirm that the practice of excursionism is neglected by the public sector, contrary to the intention of the hegemonic agent‟s intentionality present in this touristic territory which aim at the development of a lucrative activity, geared toward tourists with greater spending power. This ignored and neglected faction of Potiguar tourism is considered poor or dirty , and generate conflicts among the distinct social agents: tourists, the market and the public sector, simultaneously peaking interest, which is then appropriated by the informal sector and formal economy. Excursionism is an expressive phenomenon, a socially relevant practice, enjoyed by citizens of the working class who, in order to have a day of leisure, use alternative consumer practices and subvert various strategies of segregation that are imposed within these tourist areas, behavior that, in part, justifies the nickname, picnic lovers , given to these tourists

A teoria das representações sociais nos estudos sobre representações de professores

A pesquisa apresentada analisou 27 teses de doutorado e dissertações de mestrado de programas brasileiros de Pós-Graduação em Educação que usam a teoria de representações sociais para estudar representações de ou sobre professor. Para a realização dessa análise foram investigados, principalmente, aspectos metodológicos relacionados ao uso da TRS, tais como: modo de descrição dos sujeitos da pesquisa e variáveis selecionadas nessa caracterização; descrição do objeto de estudo, sua contextualização e justificação como objeto de representação social; procedimentos de coleta de dados, sua adequação e justificação; tratamento dos dados; procedimentos de análise; síntese dos resultados e sua contribuição para a educação, para a formação de professores e para a TRS. Concluiu-se que a TRS é pouco explorada nos trabalhos, embora, de modo geral, eles contribuam para aclarar as representações que professores têm a respeito de vários campos que compõem sua vida profissional.

Mortalidade do ácaro predador Neoseiulus californicus (Acari: Phytoseiidae) em testes de toxicidade residual de inseticidas e acaricidas usuais em pomáceas

Os ácaros fitoseídeos, especialmente Neoseiulus californicus (McGregor), são importantes agentes de controle biológico de ácaros tetraniquídeos-praga nas culturas de pomáceas no Alto Valle del Río Negro y Neuquén, Argentina. Neste trabalho, avaliou-se a mortalidade de N. californicus quando exposto a resíduos dos inseticidas azimphos-methyl, carbaryl e cyfluthrin, e dos acaricidas cyhexatin e propargite. Os produtos foram aplicados às concentrações recomendadas em plantas de pereira. Um, três, seis e dez dias após a aplicação (DAA), folhas tratadas foram retiradas das plantas para a preparação de unidades experimentais. Cinco adultos de N. californicus, provenientes de criação-estoque, foram transferidos para cada unidade, onde pólen de taboa foi fornecido como alimento. As unidades foram mantidas a 25 ± 2 ºC, 60 ± 10% de umidade relativa e fotoperíodo de 14 h. A mortalidade do ácaro foi avaliada 24 h após o confinamento. As médias de mortalidade foram comparadas pelo teste de Dunnett, a 5% de probabilidade. A progressão do declínio do efeito dos produtos testados foi submetida à análise de regressão. Nas duas primeiras datas de avaliação, todos os produtos apresentaram valores de mortalidade significativamente diferentes da testemunha tratada com água. Seis dias após a aplicação, propargite, cyhexatin e cyfluthrin apresentaram mortalidade de aproximadamente 30%, enquanto a mortalidade nos tratamentos azimphos-methyl e carbaryl apresentou níveis estatisticamente similares aos da testemunha. Dez dias após a aplicação, a mortalidade em todos os tratamentos não diferiu significativamente da testemunha. O efeito de todos os produtos apresentou declínio progressivo ao longo do período de observação, sendo significativa a 1% de probabilidade a regressão linear negativa para os valores obtidos. Os maiores efeitos negativos sobre a sobrevivência de N. californicus corresponderam aos acaricidas testados. Azimphos-methyl foi o produto que menos afetou a sobrevivência do ácaro predador. Os inseticidas testados, usados na região do Alto Valle del Río Negro y Neuquén para o controle de Cydia pomonella, praga-chave das culturas de pomáceas, apresentaram baixa toxicidade sobre N. californicus.

Germinação, qualidade sanitária e armazenamento de sementes de canafístula (Peltophorum dubium)

Neste trabalho, objetivou-se avaliar o efeito de métodos de superação de dormência e do ambiente de armazenamento sobre a qualidade fisiológica e fitopatológica das sementes de canafístula (Peltophorum dubium). As sementes foram submetidas aos seguintes tratamentos de superação de dormência: escarificação com lixa (200); imersão em água na temperatura ambiente, durante 24 e 72 h; imersão em ácido sulfúrico por 2, 6, 10, 15, 20 e 30 min; imersão em água quente (70, 80 e 90 C); e umedecimento do substrato com solução de KNO3 (0,2%). As sementes foram armazenadas na temperatura ambiente e a 10 C por 210 dias. Os efeitos dos tratamentos e do armazenamento foram avaliados por meio do teor de água, teste de germinação (cinco repetições de 30 sementes), de comprimento de plântulas e sanidade (400 sementes), com incubação por oito dias (22-25 C). Na análise estatística dos dados, utilizou-se o delineamento experimental inteiramente casualizado em esquema fatorial 2 x 14 (condições de armazenamento x tratamentos para a superação da dormência). As médias foram comparadas pelo teste de Tukey (P>0,5). Com relação às sementes não armazenadas, os melhores tratamentos para superar a dormência e promover a germinação foram escarificação com lixa ou ácido sulfúrico por 15 a 30 min; quanto às sementes armazenadas, houve a imersão em água quente (70 a 80 ºC). Os fungos detectados nas sementes foram Pestalotia sp., Alternaria sp., Rhizopus sp., Nigrospora sp., Curvularia sp., Fusarium sp., Rhizoctonia sp., Aspergillus sp., Cladosporium sp. e Fusarium semitectum.

Efeitos da adubação fosfatada nas relações de interferência entre sorgo granífero e tiririca: I. Crescimento inicial

Com o objetivo de estudar os efeitos da aplicação de doses crescentes de fósforo sobre alguns parâmetros de cr es cimento inicial de plantas de Sorghum bicolor (L.) Moench (sorgo) e Cyperus rotundus L. (tiririca) desenvolvidas isoladas ou em convivência, foi conduzido um experimento em vasos, sob condições de casa de vegetação. O delineamento experimental utilizado foi o inteiramente casualizado com cinco repetições, send que os tratamentos experimentais foram dispostos em esquema fatorial 3 x 6, onde constituíram variáveis: três condições de vegetação nos vasos (3 plantas de sorgo por vaso; população proveniente do plantio de quatro tubérculos de C. rotundus por vaso; três plantas de sorgo em convivência com a população proveniente do plantio de quatro tubérculos de C. rotundus por vaso) e seis doses de de fósforo (0,25, 50, 100, 150 e 200 mg/kg de P). Para efeito da análise estatística dos dados foi considerado dentro de cada espécie um fatorial de 2 x 6, ou seja duas condições (isolado e convivência) e seis doses de fósforo. A fase experimental teve uma duração de 50 dia s. Com base nos resultados obtidos foi verificado que ambas espécies responderam de forma crescente à elevação da dose de adubação fosfatada, ocorrendo um incremento em todas as características avaliadas, sempre em menor grau quando crescidas juntas. Este aumento só foi significativo até a dose de 100 mg/kg de P para a tir irica e 150 mg/kg de P na cultura do sorgo, quando ambas se desenvolveram isoladamente. Já em convivência, a cultura do sorgo respondeu significativamente somente a partir da dose de 50 mg/kg, sendo precisamente nestas primeiras doses onde a tiririca exerceu seu maior poder de interferência, reduzindo significativamente a área foliar e acúmulo de matéria seca em folhas e colmos de sorgo. Por sua vez, a cultura de sorgo foi mais competitiva nas maiores doses de fósforo (150 e 200 mg/kg), o que pode estar provavelmente relacionado ao maior poder de sombreamento imposto pelo cultivo sobre a planta daninha. A presença do sorgo diminuiu a área foliar e o número e acúmulo de matéria seca em brotações e tubérculos de Cyperus rotundus. Com a elevação da dose de aplicação de fósforo, a tiririca apresentou uma maior alocação de matéria seca para parte aérea, do que para tubérculos.
