Avaliação de um chiller de absorção numa unidade de cogeração e trigeração

Portugal é um país dependente da energia do exterior, devido à elevada percentagem de consumo de energia a partir de fontes primárias, como por exemplo o gasóleo. Para colmatar este cenário, têm vindo a criar-se incentivos para o uso de energias renováveis e para intensificação de medidas de eficiência energética, como os sistemas de cogeração, de forma a tornar os processos industriais nacionais mais autónomos e mais competitivos. O presente trabalho, centra-se na avaliação do chiller de absorção na central de trigeração da empresa Monteiro, Ribas-Indústria, SA, com a finalidade de identificar algum problema no funcionamento do chiller. Após efetuado o estudo do chiller, verificou-se que o coeficiente de performance do chiller apresenta valores que variam entre 0,75 e 0,81, que comparado com o valor especificado, não apresenta grande diferença. No que toca à potência do chiller, esta apresentou valores entre 948 e 1045 kW. Estes valores estavam bem abaixo da potência especificada pelos fornecedores. Assim, pretendeu-se propor medidas para melhor a potência obtida. Para o efeito foi sugerido o aquecimento da corrente que atua como fonte de calor para o chiller, a corrente de água quente. Embora a empresa apresente a solução para o problema, um permutador de vapor para o aquecimento da corrente de água quente, este não se encontra em funcionamento contínuo, levando a uma potência mais baixa.

Avaliação de megadoses de retinol palmitato no pós-parto imediato sobre o retinol do leite de puérperas atendidas no Hospital José Pedro Bezerra, Natal-RN

Vitamin A deficiency (VAD) is a serious public health problem in developing countries, and as a therapeutic and prophylactic measure retinil palmitate is being supplemented. Nevertheless its efficacy has been questioned. The objective of the study was to evaluate the supplementation of two retinil palmitate megadosis on the serum retinol levels of post partum healthy mothers from Dr. José Pedro Bezerra (Hospital Santa Catarina) hospital, Natal - RN. The enrolled women (n=199) were randomly distributed into three studied groups and supplemented with retinil palmitate immediately after delivery with a single 200,000 IU dose (group S1), two 200,000 IU dose (group S2) with 24h difference between the doses, or no supplementation (group C). Among women selected, 143 remained until the end of the study. The influence of vitamin A dietary intake was evaluated during pregnancy and after 30 days of delivery. The average intake of the population was reasonable, but a high prevalence of inadequate intake was found. Retinol in colostrums and mature milk was determined by high performance liquid chromatography (HPLC). The retinol average in colostrums and mature milk in the supplemented and control groups were adequate according to the reference values. In colostrums, women from groups C, S1 and S2 presented retinol averages by milk volume of 94.8 ± 40.2 µg/dL, 92.2 ± 50.0 µg/dL and 91.8 ± 53.7 µg/dL, respectively. No difference was found between these averages (p=0.965), this was also seen when the values where expressed as µg/g of fat (p=0.905). After 30 days of delivery, retinol per milk volume differed between the control group (36.6 ± 17.5 µg/dL) and groups supplemented with 200,000 IU (51.0 ± 28.8 µg/dL) or 400,000 IU (55.2 ± 31.6 µg/dL) of retinil palmitate (p<0,05). Nevertheless, when S1 and S2 groups where compared, no significant difference was found (p=0.97). Considering retinol/g of fat, the means were 12.7 ± 6.7 µg/g, 15.6 ± 8.3 µg/g and 17.2 ± 8.9 µg/g for groups C, S1 and S2, respectively, with significant difference between groups S2 and C (p=0,01). Subclinical VAD prevalence showed a serious public health problem in the study population (32% in colostrums and 31.5% in mature milk). When analyzing the groups separately, the group which received two doses (200,000 IU + 200,000 IU) presented the lowest VAD prevalence (20.7%). Retinil palmitate supplementations of 200,000 IU and 400,000 IU (divided in two doses) in the immediate post partum showed no significant difference. Nevertheless, the 400,000 IU (divided in two doses) supplementation showed a reduction in VAD

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

Análise da eficiência de contratos de serviços de elevada especificidade terceirizados pela petrobras

The definition of the boundaries of the firms is subject that has occupied the organizational theorists long ago, being the seminal work of Coase (1937) indicated as the trigger for one theoretical evolution, with emphasis on governance structures, which led to a modern theory of incomplete contracts. The Transaction Cost Economics (TCE) and Agency Theory arise within this evolution, being widely used in studies related to the theme. Empirically, data envelopment analysis (DEA) has established itself as a suitable tool for analysis of efficiency. Although TCE argues that specific assets must be internalized, recent studies outside the mainstream of theory show that, often, firms may decide, for various reasons, hire them on the market. Researches on transaction costs face with the unavailability of information and methodological difficulties in measuring their critical variables. There`s still the need for further methodological deepening. The theoretical framework includes classic works of TCE and Agency Theory, but also more recent works, outside the mainstream of TCE, which warn about the existence of strategies in use of specific assets that aren`t necessarily aligned with the classical ideas of TCE. The Brazilian oil industry is the focus of this thesis, that aimed to evaluate the efficiency of contracts involving high specificity service outsourced by Petrobras. In order to this, we made the categorization of outsourced services in terms of specificity, as well the description of services with higher specificity. Then, we verified the existence of relationship between the specificity of services and a number of variables, being found divergent results than those that are preached by the mainstream of TCE. Then, we designed a DEA model to analyze the efficiency in the use of onshore drilling rigs, identified among the services of highest specificity. The next step was the application of the model to evaluate the performance of drilling rigs contracts. Finally, we verified the existence of relationship between the efficiency of contracts and a number of variables, being found, again, results not consistent with the theory mainstream. Regarding to analyze of efficiency of drilling rigs contracts, the model developed is compatible with what is found in academic productions in efficiency of drilling rigs. The results on efficiency show a wide range of scores, with efficiencies ranging from 31.79% to 100%, being low the sample efficiency average. There is consonance between the model results and the practices adopted by Petrobras. The results strengthen the DEA as an important tool in studies of efficiency with possibility to use for analysis other types of contracts. In terms of theoretical findings, the results reinforce the arguments that there are situations in which the strategies of the organizations, in terms of use of assets and services of high specificity, do not necessarily follow what is recommended by the mainstream of TCE

Cultura organizacional e qualidade dos serviços turísticos :um estudo no setor de restaurantes

The present study seeks to describe the features and peculiarities of the relationship between organizational culture and the quality of tourism services, specifically in the restaurant sector, attempting to contribute toward maintaining the tourism sector of the city of Natal/RN. Thus, a descriptive and correlational study, with qualitative and quantitative approaches, of thirty-seven restaurants that are located in areas that compose the tourism corridor of Natal was undertaken. To collect the quantitative dada, the Organizational Culture Evaluation instrument of Cameron and Quinn (2006) was applied and the SERVPERF instrument of Cronin and Taylor (1992) was used to measure the quality of the services. The results suggest that the Clan and Innovation Cultures are associated with better levels of quality of services than those of the Market and Hierarchy Cultures. The relationships that were identified in this study are consistent with results found in other studies and the information reported here can serve as a basis for managers of the restaurant sector to reach excellence in their services, satisfying their customers and contributing to maintaining the tourism sector

Inércia organizacional

Ultimamente muitas investigações têm sido levadas a cabo em diferentes áreas das Ciências Sociais e Humanas, nas quais o fenómeno de inércia, suas causas e resultados têm sido estudados, a saber: na Filosofia (Ética e Praxeologia), na Psicologia ou na Teoria Organizacional. Todavia, parece que a literatura científica das Ciências Sociais, maioritariamente baseada em estudos empíricos, nos quais a inércia é uma das variáveis independentes, carece de reflexão teórica. O problema de inércia organizacional é analisado no presente artigo como um caso específico da inércia do comportamento humano. Este artigo aborda apenas algumas questões relacionadas com a inércia do comportamento humano: o problema da aplicação directa do princípio mecânico para a área psicossocial, algumas concepções deste fenómeno nas Ciências Sociais com especial enfoque na Teoria organizacional, bem como a avaliação deste fenómeno. Por estas razões, o texto concentra- se nos aspectos conceptuais do fenómeno, levantando mais questões do que dando respostas. Tem um carácter introdutório a futuras investigações.

A avaliação das escolas: efeitos da avaliação externa nas dinâmicas de autoavaliação da escola

No contexto educativo português existem, atualmente, orientações legais para que as escolas sejam, por um lado, sujeitas a processos de avaliação externa e, por outro, induzidas a criar mecanismos de autoavaliação. Embora a escola seja, pelo menos em parte, um “locus de produção normativa”, na prática não tem sido fácil o diálogo entre a avaliação externa e os processos de mudança e melhoria, através da autoavaliação institucional. Num contexto onde as politicas nem sempre criam os estímulos e as condições adequadas, a ação organizacional em torno dos processos avaliativos acaba por refletir o jogo dos atores. Face à “natureza política” da avaliação, as escolas e os seus atores recorrem a “soluções organizacionais” que lhes permitem, em função dos interesses e dos objetivos individuais e organizativos, gerir as pressões e as expetativas do seu meio institucional. O presente trabalho pretende encontrar respostas sobre os efeitos do programa de avaliação externa das escolas (AEE) nas dinâmicas de autoavaliação e nos planos de ação para a melhoria da escola. Trata-se de uma investigação inserida numa matriz de cariz essencialmente qualitativo que opta pelo estudo de casos múltiplos. A informação foi recolhida através de várias fontes: observação direta, grupo focal (focus group), entrevistas, inquérito por questionário e análise documental. Os resultados tendem a evidenciar que as organizações educativas, nas respostas às prescrições externas para a avaliação e melhoria da escola recorrem a estratégias e táticas plurais, de tal modo que as mudanças que ocorrem, mais do que respostas à necessidade de eficácia e melhoria interna da escola, traduzem-se em processos de adaptação, que variam consoante as tensões existentes entre o contexto institucional e o ambiente competitivo onde as escolas estão inseridas; Abstract: The Evaluation of Schools: Effects of External Evaluation in the dynamics of Self-evaluation of Schools In the Portuguese educational context, there are currently legal guidelines for schools to be subject to external evaluation process, on the one hand, and on the other hand induced to create self-assessment mechanisms. Although the school is at least partly a "normative production locus", in practice the dialogue between the external evaluation and the processes of change and improvement through institutional self-assessment has not been easy. In a context where the policies do not always create the incentives and the right conditions, the organizational action around the evaluative process ends up reflecting the set of actors. Before the "political nature" of the evaluation, the schools and their actors recur to "organizational solutions" that allow them, in the interests of individual and organizational goals, to manage the pressures and expectations of its institutional environment. This work aims at finding answers to the effects of the External Schools Evaluation (ESE) programme, in the dynamics of self-evaluation and action plans for the improvement of school. It is an investigation inserted into an oriented matrix, essentially of qualitative nature that opts for multiple case studies. The information was collected through various sources: direct observation, focus group, interviews, questionnaire survey and document analysis. The results tend to show that educational organizations, in response to the external requirements for assessing and improving, use plural strategies and tactics. Similarly, the changes that occur in the structures, processes and practices, more than answers to the need for efficiency and indoor improvement of the school, result into adjustment processes, that change according to the existing tensions between the institutional context and the competitive environment where schools are located.

Relações interorganizacionais e eficiência coletiva: um estudo de caso no arranjo produtivo local de confecções do Agreste de Pernambuco

This work is a study in the Local Productive Arrangement of confections from Agreste of Pernambuco, as a relevant sector in economic and social aspect. This research has as central aim to understand how the inter-organizational relations influence the collective efficiency of arrangement. The theoretical framework employed highlights the approaches that deal with the benefits of business agglomeration for the develop­ment of firms and regions. It has discussed the approach of small and medium enter­ prises and industrial districts (SCHMITZ, 1997), which introduce the concept of col­ lective efficiency, explaining that only those externalities explained by Marshall (1996) are not sufficient to explain the competitive advantage of enterprises, expand­ing the idea that organizations achieve competitive advantage not acting alone. To examine the influences of relations in the collective efficiency, it has been taken as analytical perspective theory of social networks (GRANOVETTER, 1973, 1985; BURT, 1992; UZZI, 1997) because it has believe that this approach provides subsi­ dies for a structural analysis of social relationships in face the behavior of human ac­tion. By examining the organizations in a social network, you should understand the reason of this establishment of the relationship, their benefits, and as the information flow takes place and density of links between the actors (Powell; SMITH-DOERR, 1994). As for the methods, this study is characterized as a case study, in according to the purposed objectives, in addition to qualitative method. Also, due to recovering of the historical milestones of the arrangement, it is used a sectional approach with longitudinal perspective (VIEIRA, 2004). The primary and secondary data were used in order to understand the evolutionary process of the sector and their inter-actors re­ lationships in the arrangement for the promotion of development, for both, was used the contend and documentary analysis technique, respectively (DELLAGNELO ; SIL­VA, 2005). The approach of social networks has permitted understand that social re­lationships may extend the collective efficiency of the arrangement, and therefore need to develop policies that encourage the legalization of informal companies in ar­rangement, by showing up themselves representative. Thus, the relations estab­ lished in LPA of confections from Agreste of Pernambuco need for more effective mechanisms to broaden the collective efficiency. Therefore, this way as take place has directly benefited only a group of companies that are linked in some way the sup­portive institutions. So we can conclude that the inter-actor relations have limited the collective efficiency of LPA, being stimulated by the institutions in support only to groups of entrepreneurs, even those that produce external relations for all clustered companies

Avaliação da política de segurança alimentar implementada através dos restaurantes populares do Rio Grande do Norte

This survey has to general objective to evaluate the Food Safety Policy implemented by Restaurantes Populares do Rio Grande do Norte. The survey is qualitative of type exploratory and descriptive. The universe of survey is all Units of Food and Nutrition (UAN) of the Restaurantes Populares do Rio Grande do Norte. To collects of data were used two instruments: interview and form. The interviews were intended to analyze the four axes of the Food Safety: access, food quality, production and marketing of food and organizational arrangement. The form was used to check the quality of nutrition and sanitary-hygienic food served. We used two types of forms: a spreadsheet with the weekly menu and the portions served to verify that the meals serve the nutritional needs proposed by the program; and the check-list of ANVISA to verify the sanitary-hygienic conditions in each unit. Through the survey data and analyses made observe that the access category have some problems such as lack of registration, lack of advertising of Restaurants and wastage of public resources, making policy that should be of included in a policy of exclusion. In the nutritional aspect there is neglect on the daily nutritional goal, because it is not accomplished nutritional analysis of menu offered, the nutritionists do not know what should be the nutritional value of meals served; in the hygienic-health aspect trough the problems identified is concludes that there is no guarantee of food quality hygienic-sanitary, committing the program as a Food Safety Program. About the production and marketing of food is observed some problems as: the goal of sale of meals is not achieved in full, the purchase of genres does not stimulate the local economy, nor generates jobs and income, and inefficient performance of the MEIOS's supervision. In the analysis of organizational arrangement is concluded that the partnerships are beneficial, despite some negative points, therefore, are these partnerships the problems of non-compliance, as both the MEIOS and Nutriti of important criteria established in the partnership. Therefore, it is understood that the Programa Restaurantes Populares in its original formulation is proposed to be a food safety policy, but has some problems that impossible to meet its goal, making it unprofitable like Food Safety Policy

Diagnóstico da cultura organizacional em hospitais da rede privada de Natal/RN

As peculiaridades presentes no ser humano são observadas a partir da manifestação de sua cultura. Estas manifestações podem ser influenciadas pelo contexto social do indivíduo. A cultura nacional é uma destas influências. A brasileira, por exemplo, possui alguns traços nacionais peculiares ao seu povo que amenizam a sua complexidade e pluralidade. Estes traços podem se tornar influentes na cultura organizacional, através da manifestação das práticas e dos valores utilizados pela organização. Diante disso, o presente trabalho teve como objetivo diagnosticar a cultura organizacional dos hospitais, enfatizando as práticas e os valores organizacionais e a percepção dos colaboradores sobre a cultura organizacional. A metodologia utilizada na pesquisa foi de caráter descritivo e explicativo. A pesquisa ocorreu através da aplicação do Instrumento Brasileiro para a Avaliação da Cultura Organizacional IBACO, com 283 sujeitos distribuídos em três hospitais da rede privada de Natal/RN. As evidências encontradas pelo estudo foram analisadas através do software estatístico SPSS, com as técnicas multivariadas de análise fatorial, análise de aglomerados e análise discriminante. A partir dessas análises, foram obtidos cinco fatores distribuídos entre práticas e valores apresentados pelo IBACO, que foram: as práticas de recompensa e treinamento; integração externa e promoção do relacionamento interpessoal; e, os valores de satisfação, bem-estar e cooperação dos empregados e profissionalismo competitivo. Os grupos encontrados na análise apresentaram divergências de opinião quanto às práticas e os valores utilizados nos hospitais. Concluiu-se, portanto, que o Hospital A apresentou uma cultura mais proativa e voltada mais para a satisfação e bem-estar dos funcionários. Já os outros dois hospitais apresentaram culturas semelhantes, com limitações quanto à valorização do bem-estar e da cooperação entre os colaboradores, porém com uma boa prática do relacionamento interpessoal

An analysis of workforce efficiency using organization expenses indicators

The objective of this paper is to carry out an evaluation of employee efficiency in the United States using a professional data base, namely the ECS Survey on Workforce Efficiency (2000/2001) conducted by Watson Wyatt, which includes the responses of 453 organizations covering 1,685,336 employees. To that end, we measure workforce efficiency of US organizations, differentiated by profit status, industry sector and employee size, using expenses indicators. Our findings reveal that new employee strengths will depend upon developing and using the kinds of information and analyzes that can keep workers, educators, employers and employee program administrators abreast or ahead of changing conditions.

Avaliação do potencial eólico da zona de Évora - Contribuição para a redução de emissões de CO2

Neste trabalho é analisado o potencial eólico da região de Évora, tendo sido considerados quatro locais: Mitra, Portel, Reguengos e Colégio Verney. Com os dados de potência obtidos, foram escolhidas duas turbinas existentes no mercado, de potências nominais diferentes, para uma análise mais objectiva do real potencial da região. Apurou-se que, com a instalação de três turbinas menores, se obtém praticamente a mesma potência, por um preço consideravelmente inferior. Foi ainda possível verificar-se que a quantidade evitada de C02 para a atmosfera, ao considerar uma turbina de 5000 W (B) ou três 1000 W (A), é semelhante, concluindo-se que, considerando a eficiência, potencial, preço e emissões de co2 evitadas, a instalação de diversas turbinas A é a melhor opção. Este trabalho reveste-se de particular interesse considerando o facto de ser do conhecimento geral que, nas regiões costeiras e montanhosas, o potencial eólico está bastante estudado, ao passo que nas regiões interiores tal não acontece. ABSTRACT: ln this work, we assess the potential wind power in Évora, and four locations have been considered: Mitra, Portel, Reguengos and Évora. Based on the local wind power potential, two kinds of turbines were selected, for a more objective analysis of the region's useful wind power. It was found that the option for three small turbines allows the extraction of the same wind power that is extracted by the bigger turbine and at a considerably lower installation cost. lt was also found that the reduction in co2 emissions to the atmosphere, when considering the cases of one 5000 W (B) turbine and three 1000 W (A) turbines, is similar, therefore was concluded that, given the efficiency, potential, price and reduction of C02 emissions, the installation of several A turbines is the best option. This work is of particular interest because in coastal and mountain areas the wind potential is quite known, while this is not the case of inland areas.

Estudo de um método de avaliação de desempenho aplicado aos técnicos de radiologia do Hospital Curry Cabral

A avaliação do desempenho e a sua aplicação são, no actual enquadramento socioeconómico, cada vez mais necessárias, como forma de melhorar a eficácia e a eficiência entre as organizações. Para a prática profissional verifica-se que a implementação da avaliação de desempenho, apresenta lacunas que podem comprometê-la. Sabendo da importância do profissional para o sucesso da implementação da avaliação de desempenho, toma-se fundamental, analisar a sua percepção face ao modelo e sua implementação. O problema da instrução do presente estudo pretende saber quais as percepções dos técnicos de radiologia avaliados sujeitos ao modelo de avaliação de desempenho implantado no Hospital Curry Cabral. Tendo como objectivo ao nível da gestão, minimizar os obstáculos de implementação e maximizar os pontos fortes. Após pesquisa bibliográfica sobre os principais conceitos, foi definido domo objectivo da investigação empírica: - Comparar as percepções dos técnicos de radiologia submetidos ao modelo de avaliação desempenho ”Pró-Activo”. Recorrendo a uma metodologia exploratória e descritiva, estudámos o impacto dessas ferramentas utilizadas dentro da Unidade Hospitalar do estudo. A metodologia de recolha de informação aos profissionais expostos do estudo assentou em questionários de perguntas fechadas e abertas ambas com uma abordagem de carácter quantitativo. Para a análise e tratamento dos dados utilizou-se programas informáticos. As principais conclusões: verifica-se a falta de formação para todos os envolvidos, um processo desprovido de imparcialidade, neutralidade e rigor, bem como uma motivação geral dos profissionais em matéria de avaliação de desempenho. ABSTRACT - The evaluation of performance and its implementation are, in the current socioeconomic framing, each time more necessary as form to improve the effectiveness and the efficiency amidst the organizations. For the practical professional it is verified that the implementation of the performance evaluation, presents gaps that can compromise it. Knowing the importance of the individuals in the success of the implementation of the performance evaluation, it becomes basic to analyze its perceptions face to the model and its implementation. The problem of inquiry of this study pretends to know which the perceptions of the technicians of radiology evaluated and appraisers face to the models of evaluation of performance implanted in the Portuguese Hospitals (Hospital Curry Cabral). The purpose to the level of the management is to minimize the obstacles of implementation and to maximize the strong points. Bibliographical research on the main concepts was effectuated, after what we define the objectives of empirica inquiry: - To compare the perceptions of the radiology technicians subjected to models of performance evaluation “Pro-Activa”. Using an exploratory and descriptive approach, studied the impact of these tools used in the hospitals of the study. The methodology for collecting information to professionals out of the study based on questionnaires of both open and closed questions with a quantitative approach to nature. For analysis and data processing software was used. The main conclusions: there is the lack of training for all involved, a process devoid of impartiality, neutrality and accuracy, as well as a general motivation of the professionals regarding the evaluation of performance.
