Benchmarking e regulação do setor de distribuição de energia elétrica nacional: proposta para avaliação dos custos operacionais eficientes

In Brazil, the National Agency of Electric Energy (ANEEL) represents the energy regulator. The rates review have been one of its main tasks, which establish a pricing practice at a level to cover the efficient operating costs and also the appropriate return of the distributors investments. The changes in the procedures to redefine the efficient costs and the several studies on the methodologies employed to regulate this segment denote the challenge faced by regulators about the best methodological strategy to be employed. In this context, this research aims to propose a benchmarking evaluation applied to the national regulation system in the establishment of efficient operating costs of electricity distribution utilities. The model is formulated to promote the electricity market development, partnering with government policies ant to society benefit. To conduct this research, an integration of Data Envelopment Analysis (DEA) with the Stochastic Frontier Analysis (SFA) is adopted in a three stages procedure to correct the efficiency in terms of environmental effects: (i) evaluation by means of DEA to measure operating costs slacks of the utilities, in which environmental variables are omitted; (ii) The slacks calculated in the first stage are regressed on a set of environmental variables by means of SFA and operating costs are adjusted to account the environmental impact and statistical noise effects; and, (iii) reassess the performance of the electric power distribution utilities by means of DEA. Based on this methodology it is possible to obtain a performance evaluation exclusively expressed in terms of management efficiency, in which the operating environment and statistical noise effects are controlled.

Avaliação da efetividade do Programa de Alimentação do Trabalhador

This study analyzed the Worker’s Healthy Eating Program in Rio Grande do Norte state (RN) to assess its possible impact on the nutritional status of the workers benefitted. To that end, we conducted a cross-sectional observational prospective study based on a multistage stratified random sample comparing 26 small and medium-sized companies from the Manufacturing Sector (textiles, food and beverages, and nonmetallic minerals) of RN, divided into two equal groups (WFP and Non WFP). Interviews were conducted at each company by trained interviewers from Tuesday to Saturday between September and December 2014. Data were collected on the company (characterization and information regarding the program’s desired results) and workers (personal and professional information, anthropometrics, health, lifestyle and food consumed the previous day). Population estimates were calculated for RN on the characteristics of workers and the study variables. The main variable was BMI. The secondary variables were waist circumference (WC), nutritional diagnosis, calorie intake, blood pressure, metabolic variables and lifestyle indicators. The statistical method used was hierarchical mixed effects linear regression for interval variables and hierarchical mixed effects logistic regression for binary variables. The variables measured in ordinal scales were analyzed by ordinal logistic regression adjusted for correlated variables, adopting robust standard errors. The results for interval variables are presented as point estimates and their 95% confidence intervals; and as odds-ratios and their 95% confidence intervals for binary variables. The Fisher’s exact and Student’s t-tests were used for simple comparisons between proportions and means, respectively. Differences were considered statistically significant at p<0.05. A total of 1069 workers were interviewed, of which 541 were from the WFP group and 528 from the Non WFP group. Subjects were predominantly males and average age was 34.5 years. Significant intergroup differences were observed for schooling level, income above 1 MW (minimum wage) and specific training for their position at the company. The results indicated a significant difference between the BMI of workers benefitted, which was on average 0.989 kg/m2 higher than the BMI of workers from the Non WFP group (p=0.002); and between the WC, with the waist circumference of WFP group workers an average of 1.528 cm larger (p<0.05). Higher prevalence of overweight and obesity (p<0.001) and cardiovascular risk (p=0.038) were recorded in the WFP group. Tests on the possible effect of the WFP on health (blood pressure and metabolic indicators) and lifestyle indicators (smoking, alcohol consumption and exercise) were not significant. With respect to worker’s diets, differences were significant for consumption of saturated fat (lunch and daily intake), salt (lunch, other meals and daily intake) and proteins (other meals and daily intake), with higher consumption of these nutrients in the WFP group. The study showed a possible positive impact of the WFP on nutritional status (BMI and WC) among the workers benefitted. No possible effects of the program were observed for the lifestyle indicators studied. Workers benefitted consumed less salt, saturated fat and protein. The relevance of the WFP is recognized for this portion of society and it is understood that, if the program can reach and impact those involved, the development of educational initiatives aimed at nutritional and food safety may also exert a positive influence.

Avaliação clínica e da qualidade de vida utilizando dois protocolos para recuperação miofuncional em pacientes que se submeteram à cirurgia ortognática: resultados preliminares

The objective of this randomized, blind and prospective clinical trial was to compare the pain, the edema, the mandibular movements, the masticatory efficiency and life quality, in the first 60 days after surgery using 2 different clinical protocols for myofunctional recovery, in patients who underwent orthognathic surgery. A sample of 19 patients was used and divided into 2 groups. The control group (CG) consisted of 10 patients who had postoperative rehabilitation guided by a standard protocol, conducted by the Service of Surgery and Traumatology Oral and Maxillofacial. In other hand, the experimental group (EC) totaled 9 patients who received the speech therapy rehabilitation protocol specialized, by professionals in the area. The variables pain, edema and mandibular movements were analyzed during 48h, 96h, 7 days, 14 days, 30 and 60 days post-surgery. The masticatory efficiency and the quality of life were classified with 60 days after surgery . The data were submitted an analysis of variance, Student's t-test and Fisher's independence, at the level of 5% probability. It was identified that patients of GE have benefited in the first 14 days(p<0,001), as they have had reported less pain than those in the CG. Significant statistics differences between groups for pain parameters (after 14 days) (p=0,065), edema(p=0,063), mandibular movements(p=0,068), masticatory efficiency(p=0,630) and the impact on quality of life (p=0,813) were not observed on this study. The speech therapy protocol for myofunctional recovery (EG), although it has not obtained statistical results superiors than the CG in the general context, presents itself as a viable alternative to conventional therapy assumed by many maxillofacial surgeons, allowing the surgeon to optimize time with patients in the period postoperatively.

Avaliação da soldagem GMAW mecanizada e automatizada para união de dutos utilizando fontes convencional e com controle de curto- circuito

Welding is one of the most employed process for joining steel pipes. Although, manual welding is still the most used one, mechanized version and even automatized one have increased its demand. Thus, this work deals with girth welding of API 5L X65 pipes with 8” of nominal diameter and 8.0 mm thickness, beveled with V-30º narrow gap. Torch is moved by a bug carrier (mechanized welding) and further the parameters are controlled as a function of angular position (automatized welding). Welding parameters are presented for filling the joint with two-passes (root and filling/capping passes). Parameters for the root pass were extracted from previous author´s work with weldments carried out in plates, but validated in this work for pipe welding. GMAW processes were assessed with short-circuit metal transfer in both conventional and derivative modes using different technologies (RMD, STT and CMT). After the parameter determination, mechanical testing was performed for welding qualification (uniaxial tension, face and root bending, nick break, Charpy V-notch impact, microhardness and macrograph). The initially obtained results for RMD and CMT were acceptable for all testing and, in a second moment, also for the STT. However, weld beads carried out by using the conventional process failed and revealed the existence of lack of fusion, which required further parametrization. Thus, a Parameter-Variation System for Girth Welding (SVP) was designed and built to allow varying the welding parameters as a function of angular position by using an inclinometer. The parameters were set for each of the three angular positions (flat, vertical downhill and overhead). By using such equipment and approach, the conventional process with parameter variation allowed reducing the welding time for joint accomplishment of the order of 38% for the root pass and 30% for the filling/capping pass.

Características de virulência, resistência e diversidade genética de sorovares de Salmonella com impacto na saúde pública, isolados de frangos de corte no Brasil /

Salmonella Enteritidis, S. Typhimurium and S. Infantis are often associated with cases of human infections worldwide and is transmitted through consumption of contaminated food, particularly those of animal origin, especially chicken meat. This thesis was fractionated into three chapters, the first one relating to general considerations about the topics discussed in the following chapters. The second chapter aimed to evaluate virulence characteristics, antimicrobial resistance and the genetic similarity of 51 strains of S. Infantis isolated in samples of poultry origin from an industry located in the state of São Paulo, Brazil, during the 2009 to 2010 period. The third chapter aimed to analyze 111 strains of S. Enteritidis, 45 of Salmonella Typhimurium and 31 of Salmonella Typhimurium monophasic variant I 4, [5], 12:i:- isolated from chicken carcasses in different brazilian slaughterhouses from 2009 to 2011, and to estimate the risk to human health, based on the presence of virulence genes and antimicrobial resistance, correlating to the pathogenicity profiles (antimicrobial resistance and presence of virulence and resistance genes) with the genetic profile (ribogroup) of the isolates. To evaluate the antimicrobial susceptibility was performed the disk diffusion test for all serotypes of Salmonella, and exclusively to S. Enteritidis and S. Typhimurium, was also verified the minimum inhibitory concentration for ciprofloxacin and ceftazidime antibiotics. The presence of virulence genes invA (invasion), lpfA (fimbriae-adhesion), agfA (fimbriae-biofilm) and sefA (fimbriae-adhesion) were evaluated by PCR. The strains that showed resistance to antibiotics of β-lactams class were evaluated for the presence of resistance genes blaTEM, blaSHV, blaCTX-M and blaAmpC. For resistant strains to quinolones and fluoroquinolones antibiotics classes were searched the qnrA and qnrS genes. The phylogenetic relationship among the isolates was determined by RAPD method for S. Infantis strains, and by ribotyping technique to S. Enteritidis and S. Typhimurium.

Impacto do trabalho noturno na qualidade de vida do profissional de enfermagem do gênero masculino

The nursing staff is now the largest contingent of professionals in healthcare environments, with more than 1.8 million professionals, and of these 15% are men, showing a masculinization of the historical profession and culturally conceived and carried out by women (COFEN / FIOCRUZ, 2013). This dissertation discusses the profession forward to some issues related to gender, quality of life and night work. Objective: To analyze the impact that shift work has the professional quality of life male, through a specific instrument to identify the main problems and joint damage to that front group to his professional activity. Methods: descriptivo, Cross-sectional study with a quantitative approach, performed with 72 professional male nursing staff, 41 (56.9%) nursing technicians, 18 (25%) of nursing assistants and 13 (18.1%) of nurses, in January 2015 in a university hospital in the city of Uberlândia (Minas Gerais). For this, we used the WHOQOL-BREF questionnaire. Quantitative variables were described as mean, standard deviation, maximum and minimum, in addition to the Shapiro-Wilk test and Kruskal-Wallis used in the data analysis, with a confidence level of 5% (p <0.05). Results: the profile of respondents, most are married 42 (58.3%) under the employment contract via Single Legal Regime 50 (69.4%) with mean age of 40 and having 16 years of service; and within a range of 0 to 100, the areas with better evaluation were the Social Relations (70.1) and psychological (67.5); already the worst were the Environment (57.4) and Physical (65.4). In the overall assessment, the average was 63.3 and staying below the national average (65-70). Thus, the professionals who were married obtained better scores, regardless of the category which is in the nursing team. Conclusions: The group is average, taking into account the standard deviation, but we can say that working conditions affect their profession, and these results allow the detection of the difficulties experienced by men of the nursing team, and can cooperate with the design strategies that benefit or minimize the search for conflicts that affect the health of these workers and their quality of life.

Avaliação da eficácia da implementação de um pacote de medidas na prevenção de pneumonia associada à ventilação mecânica em unidade de terapia intensiva adulta

Background: Ventilator-associated pneumonia (VAP) is a health care related infection and the second leading cause of nosocomial infections linked to morbidity and mortality rates. Therefore, the implementation of care guideline protocols has become necessary for critically ill patients in ICUs in order to provide adequate treatment. Objective: To assess the impact of a package called FAST HUG in PAV ; analyze the risk factors for occurrence of VAP in adult patients at an ICU of a private hospital ; analyze the clinical characteristics of patients who were or were not submitted to the FAST HUG ; analyze the etiology of microorganisms related to EPI ; determine the cost of hospitalization in patients with pneumonia and in patients who received the FAST HUG.Methods: The study was performed in a private hospital that has an 8-bed ICU. It was divided into two phases: before implementing FAST HUG, from August 2011 to August 2012 and after the implementation of FAST HUG, from September 2012 to December 2013. An individual form for each patient in the study was filled out by using information taken electronically from the hospital medical records. The following data for each patient was obtained: age, gender, reason for hospitalization, the use of three or more types of antibiotics, length of stay, intubation time and progress. Findings: After the implementation of FAST HUG, there was an observable decrease in the occurrence of VAP (p <0.01), as well as a reduction in mortality rates (p <0.01). It also shows that the intervention performed in the study resulted in a significant reduction in ICU hospital costs (p <0.05).Conclusion: The implementation of FAST HUG reduced the cases of VAP. Thus, decreasing costs, reducing mortality rates and length of stay, which therefore resulted in an improvement to the overall quality of care.

O Impacto das Experiências de Vergonha nos Adolescentes

A presente investigação pretendeu ver cumpridos três dos seus principais objectivos: 1) Adequar e analisar os instrumentos de avaliação em adolescentes, garantindo, medidas confiáveis dos constructos em estudo; 2) Examinar o impacto das experiências de vergonha, verificando se estas podem funcionar como acontecimentos determinantes e centrais na formação da identidade do adolescente; 3) Explorar a relação entre as experiências de vergonha e sintomas de desajustamento psicológico (sintomas de depressão, ansiedade e stress). A amostra é constituída por 397 jovens (190 rapazes e 207 raparigas), com idades compreendidas entre os 12 e os 18 anos (M= 14,91) a frequentar o ensino básio e secundário do sistema regular de ensino. Para além do CES que foi objecto de uma análise mais detalhada, preencheram igualmente os seguintes questionários: ISS, OAS e DASS-21. Os resultados obtidos mostram que indivíduos cujas memórias de vergonha se tornaram pontos de referência na sua identidade, tendem a manifestar valores mais elevados de vergonha externa e vergonha interna. Verificou-se também que indivíduos que apresentam centralidade das memórias de vergonha evidenciam maior vulnerabilidade à sintomatologia psicopatológica, nomeadamente depressão, ansiedade e stress. Por fim, constatou-se que tanto a vergonha externa, como a vergonha interna em adolescentes se apresentam correlacionadas com a psicopatologia. No entanto, a vergonha interna surge mais associada à depressão que a vergonha externa, que se correlaciona mais com a ansiedade e o stress. No que respeita à adaptação das escalas CES, OAS e ISS para a população adolescente, verificou-se que apresentaram boas qualidades psicométricas. Podemos concluir com a nossa investigação, que tal como na população adulta, os adolescentes que experienciaram memórias de vergonha que se tornaram centrais na sua identidade e história de vida, tendem a manifestar níveis mais elevados de vergonha externa e interna. Por outro lado, encontram-se também mais propensos a desenvolver sintomatologia psicopatológica, como a depressão, ansiedade e stress.

Estudo do Impacto da Desinstitucionalização de Doentes e /ou Deficientes Mentais no seu Bem-estar Psicológico: uma experiência de reabilitação psicossocial – “Quinta Pedagógica das Romãzeiras”

O presente estudo analisa uma experiência de desinstitucionalização de pacientes que se encontravam internadas na Casa de Saúde Rainha Santa Isabel, em Condeixa-a- Nova, visando a sua inserção socio-comunitária, através da integração num projecto, que tem por nome “Quinta Pedagógica das Romãzeiras” apoiado num programa de reabilitação psicossocial (THS – Treino de Habilidades Sociais) e de Actividades de Vida Diária (AVDs). O universo do estudo compreendeu um grupo de vinte pacientes que foram acompanhados na sua trajectória de desinstitucionalização e avaliados em dois momentos com um intervalo de oito meses. A primeira avaliação foi feita antes da desinstitucionalização de modo a obter os valores relativos ao estado psicológico e psicopatológico das utentes internadas. A segunda avaliação foi feita após a desinstitucionalização e a intervenção da equipa técnica através do respectivo projecto de reabilitação psicossocial. As duas áreas avaliadas foram: O índice Geral de Sintomas Psicopatológicos (Sintomatologia Psiquiátrica) e o nível de Bem-Estar Psicológico. Os resultados deste estudo apontam no sentido, globalmente, existirem mudanças positivas consideradas estatisticamente significativas nos índices de sintomatologia, entre os dois momentos de avaliação. No que diz respeito à área de Bem-Estar Psicológico, os resultados revelam igualmente diferenças consideradas muito significativas entre os dois momentos de avaliação. O factor que se destacou mais foi o factor da Felicidade e da Auto-estima. O factor que menos se destacou foi o da sociabilidade. Estes resultados traduzem o impacto importante do processo de desinstitucionalização no aumento do Bem-estar Psicológico das pessoas com deficiência e/ou doença mental, institucionalizadas em internamento de longo termo. Os resultados também perspectivam uma mudança na qualidade de vida assim como na redução da sintomatologia, influenciando positivamente e de forma indirecta os resultados do impacto do processo de desinstitucionalização.

O Sistema de Gestão e Avaliação do Desempenho na Administração Pública Portuguesa: efeitos da sua prática no contrato psicológico dos colaboradores

Desde as últimas décadas do século XX que, perante um cenário marcado pela complexidade de uma economia globalizada, a Administração Pública tem sido coagida a passar por processos de reforma. As referências à reestruturação da Administração Pública por motivos políticos, económicos e financeiros, são frequentes na literatura, e surgem, quase sempre, num discurso imperativo. Neste contexto, foram introduzidos mecanismos de mercado por se acreditar que estes produzem soluções mais eficazes para o cidadão-cliente, uma administração motivadora, para quantos nela trabalham, e eficiência económica. Na esfera pública, mais do que transformar inputs em outputs, importa, avaliar os outcomes, isto é, o impacto sobre o valor público. Inúmeros estudos concorreram para enquadrar e justificar a reforma do sector público. Continuam, porém, a faltar respostas de como compatibilizar a gestão orçamental com práticas ideológicas das organizações, nomeadamente ao nível da gestão de recursos humanos. Este estudo tem como objectivo central contribuir para um melhor conhecimento dos efeitos que a prática da avaliação do desempenho, em vigor na Administração Pública Portuguesa, tem no contrato psicológico dos colaboradores. Para o teste das hipóteses propusemos um modelo de investigação, tomando como referência a teoria de Guest. Com uma abordagem qualitativa, construímos um inquérito por questionário, que foi aplicado a alguns colaboradores de uma Instituição pública. Os dados recolhidos permitiram a elaboração de quadros de referência de resultados que, por meio da análise de conteúdo, nos possibilitou tirar ilações acerca do comprometimento organizacional e comportamentos de cidadania organizacional dos Colaboradores. Trata-se de uma pesquisa com características exploratórias que, acreditamos, possa ser a base para trabalhos futuros sobre os efeitos do SIADAP nos indivíduos e nas organizações. Os resultados mostram que o sentimento de que a organização não cumpriu os termos do contrato psicológico é moderado por um esforço emocional, que mantém o colaborador na organização, evidenciando, ainda, um comprometimento afectivo com a Instituição e comportamentos de virtude cívica. / Since the last decades of the 20th century, in a scenario marked by the complexity of a globalized economy, the Public Administration has been forced to undergo reform processes. References to the restructuring of the Public Administration for political, economical and financial reasons are frequent in literature, and arise, in most cases, in an imperative tone. In this context, market mechanisms were introduced, as it is believed that they produce more efficient solutions for the citizen-client, motivated administration for whom many work, and economic efficiency. In the public sphere, more than just transforming inputs into outputs, it is important to evaluate the outcomes, that is, the impact on the public value. Numerous studies have contributed to contextualize and justify the public sector reform. However, there are still no answers of how to develop compatibility between the budgetary management and the ideological practices of the organizations, namely on the level of human resource management. The main aim of this study is to contribute to a better knowledge of the effects that the practice of performance appraisal, in force in the Portuguese Public Administration, has on the employee's psychological contract. For this hypothesis test, we proposed a research model, with reference to Guest's theory. With a qualitative approach, we constructed a survey questionnaire that was applied to some employees of a Public Institution. The data gathered allowed the elaboration of results frameworks which, by means of the content analysis, enabled us to draw conclusions of the employees' organizational commitment and organizational citizenship behaviour. It is a research with exploratory characteristics, which we believe, may provide the basis for future work on the effects of the SIADAP on individuals and organizations. The results indicate that the feeling that the organization did not fulfil the psychological contract terms is moderated by an emotional effort, which leads the employee to remain in the organization, also showing an affective commitment to the institution and civic virtue behaviours.

Os Efeitos da Avaliação Psicológica em Crianças com Dificuldades de Aprendizagem

O presente estudo de caso agregado teve como objetivo primordial avaliar em que medida os recursos terapêuticos utilizados durante o tempo de avaliação psicodiagnóstica (psicométrica e projetiva) das crianças encaminhadas para o serviço de psicologia escolar, tem impacto positivo na criança em processo de avaliação, no duplo plano comportamental e cognitivo. O protocolo da investigação foi composto por: desenho de família, WISC-III e CAT, com recurso a algumas sessões de ludoterapia. Os meios utilizados no processo de avaliação permitiram a superação de algumas dificuldades apresentadas pelas crianças, tendo sido, muito particularmente, identificados os contributos que a psicanálise e a psicologia psicodinâmica podem oferecer à psicopedagogia. / The main objective of this aggregated case study was the assessment of the impact of psycho-diagnostic evaluation (psychometric and projective testing) on the improvement of the school-aged children oriented to the cabinet of psychology of their school. The research protocol included: family picture test, WISC -III and CAT, plus some play therapy sessions. Some of the children overcame part of the learning and behavioral difficulties after the evaluation period. Such a result proves, most particularly, the contributions of psychoanalysis and psychodynamic psychology to psycho-pedagogy.
