Avaliação da capacidade para o trabalho do servidor público: um estudo de caso em uma instituição federal de ensino superior

The ability to work, considered as resulting from a dynamic process between the individual resources in relation to their work, influenced from various factors such as sociodemographic, lifestyle, aging process and requirements of work. Aiming analyze the ability to work in a population of public servants, the study analyzed 132 public servants volunteers of the infrastructure sector, in a Federal Institution of Higher Education of the state of Rio Grande do Norte, Northeast, Brazil. Data were collected through a questionnaire called the Index of Capacity for Work - ICT. The variable analysis was done by using descriptive statistics of means, standard deviations, median minimum and maximum values of the scores of quantitative variables. The joint analysis of the variables was performed by multiple linear regression. The server had low capacity to work 11 (8.33%), moderate 31 (23.48%), good 54 (40.91), and Great 28 (21.21). Multiple regression analysis, adjusted for age, sex, education, age started to work, length of service, current capacity and full of disease, showed that best explained the variation of the CTI were age, current capacity and full of disease. The survey showed that 75% of the servers showed ICT below 43, so capacity low, moderate or good and only 25% of respondents had the CTI servers over 43 points, so great capacity for work. According to the recommendations of FIOH - Finnish Institute of Occupational Health, for servers that have these scores be implemented whose objective is to restore the ability to work which is low, improving the capacity for moderate work, support the capacity for the good work and maintain the ability to work great. Therefore, we recommend that the ICT is implemented in other units of the IFES survey in the perspective of achieving a real situation of all its servers, enabling the implementation of these measures as necessary to promote recovery and health of its employees.

Valorização do servidor no Programa Nacional de Humanização: estudo em um hospital universitário

It is at the work environment where value of the health professional is realized, according to the National Humanization Policy (PNH) from a Pediatric Hospital connected to an institution of higher education. Among the guiding principles of PNH it is highlighted the commitment to the democratization of labor relations and enhancement of health professionals, stimulating the continuing education process. For this research, a qualitative approach was chosen, using a semistructured interview as a tool to collect data. In a perspective of identifying the appreciation and humanization into interpersonal relations between workers, information from the theory of communicative action of Habermas was analyzed, considering cultural values goes beyond the practice in action, where the prospects of moral arguments in the universal truisms of life pervade original cultural moral, cognitive and expressive, imbued on ethics. This reasearch had the collaboration 29 employees with a regular contract labor to a teaching hospital in Natal, Brazil. The data was obtained through interviews which all participants signed a consent term. After data analysis the results shows the existance of a satisfaction of all workers on performing duties. The workers perceive its role valorization through kudos received as a consequence of a work done, others believe that it occurs when the institution or the group itself is concerned to enhance the work. Thus, in general, they feel valued. Regarding the interpersonal relationship, the most highlighted point was the fact that in the employees versus general directors item, respondents indicated the existence of a distance between these two categories, which can affect a participatory management. Therefore, the results of this study showed the necessity to develop actions that provide a healthy work environment. The joint guidelines of the PNH and the Employee Health Care Policy, represent some directions with some similarities in their purpose to the theory of communicative action, where there is a mutual respect, tolerance and coexistence of differences, considering the constructive conflict among health workers within the perspective of communication and interaction among individuals

Estratégias de identificação paramétrica aplicadas à modelagem dinâmica de um servidor web Apache

Este artigo apresenta um estudo experimental de técnicas de identificação paramétrica aplicadas à modelagem dinâmica de um servidor web Apache. Foi desenvolvido um arranjo experimental para simular variações de carga no servidor. O arranjo é composto por dois computadores PC, sendo um deles utilizado para executar o servidor Apache e o outro utilizado como um gerador de carga, solicitando requisições de serviço ao servidor Apache. Foram estimados modelos paramétricos auto-regressivos (AR) para diferentes pontos de operação e de condição de carga. Cada ponto de operação foi definido em termos dos valores médios para o parâmetro de entrada MaxClients (parâmetro utilizado para definir o número máximo de processos ativos) e a saída percentual de consumo de CPU (Central Processing Unit) do servidor Apache. Para cada ponto de operação foram coletadas 600 amostras, com um intervalo de amostragem de 5 segundos. Metade do conjunto de amostras coletadas em cada ponto de operação foi utilizada para estimação do modelo, enquanto que a outra metade foi utilizada para validação. Um estudo da ordem mais adequada do modelo mostrou que, para um ponto de operação com valor reduzido de MaxClients, um modelo AR de 7a ordem pode ser satisfatório. Para valores mais elevados de MaxClients, os resultados mostraram que são necessários modelos de ordem mais elevada, devido às não-linearidades inerentes ao sistema.
