Organização institucional da UFPA no contexto da Reforma do Estado: uma análise dos modelos de gestão e processos na Implantação do Sistema Integrado de Ensino – SIE/2005 a 2009

A Reforma Gerencial do Estado levou as Universidades Federais de Ensino Superior a buscar tecnologia para modernizar a Gestão acadêmica aumentando a qualidade no atendimento. O Sistema Integrado de Ensino (SIE) foi implantado em 2006. Lança-se os seguintes problemas: Quais gargalos encontrados na implantação do SIE foram responsáveis pelas não implementações do estabelecido? Em que medida o modelo do SIE para gerenciamento administrativo dos assuntos acadêmicos contribuiu para a eficiência da gestão na UFPA, assim fornececendo suporte para o avanço do ensino e da pesquisa? O processo de implantação foi suficiente para dizer que estava dentro das exigências da GesPública? Para atender o objetivo Geral de analisar se os modelos de gestão praticados pelos gestores na implantação do SIE estão de acordo com o instrumento de aplicação do Plano Nacional de Gestão Pública e Desburocratização – GesPública (PBQP), o Plano Diretor Institucional e os Planos Anuais de Gestão da UFPA utilizou-se de entrevistas, questionários e de análise documental. As categorias liderança, estratégia e Plano, cidadãos e sociedade, processos e pessoas; resultados; informações e conhecimentos são da GesPública. As hipóteses validadas parcialmente dizem que a instituição avançou na utilização das Teorias Organizacionais nos aparatos administrativos e tecnológicos estando em consonância com o contexto da Reforma do Estado. As práticas de qualidade são adequadas, em início de implantação, com pontos que precisam ser melhorados. Deixam enormes espaços na modernização da gestão acadêmica. Os líderes deveriam ter inseridos os usuários no processo e trabalhado suas experiências e necessidades buscando resultados conforme prevê a Teoria Neo-Institucional e a Teoria da Qualidade que envolve as pessoas nas tomadas de decisões, pois são elas que lidam diretamente com os equipamentos e com os clientes.

Green-Markov models - new optimization strategies: a case study for user allocation in co-channel macro/femto networks

ABSTRACT: The femtocell concept aims to combine fixed-line broadband access with mobile telephony using the deployment of low-cost, low-power third and fourth generation base stations in the subscribers' homes. While the self-configuration of femtocells is a plus, it can limit the quality of service (QoS) for the users and reduce the efficiency of the network, based on outdated allocation parameters such as signal power level. To this end, this paper presents a proposal for optimized allocation of users on a co-channel macro-femto network, that enable self-configuration and public access, aiming to maximize the quality of service of applications and using more efficiently the available energy, seeking the concept of Green networking. Thus, when the user needs to connect to make a voice or a data call, the mobile phone has to decide which network to connect, using the information of number of connections, the QoS parameters (packet loss and throughput) and the signal power level of each network. For this purpose, the system is modeled as a Markov Decision Process, which is formulated to obtain an optimal policy that can be applied on the mobile phone. The policy created is flexible, allowing different analyzes, and adaptive to the specific characteristics defined by the telephone company. The results show that compared to traditional QoS approaches, the policy proposed here can improve energy efficiency by up to 10%.

Contribuição da competência em informação para os processos de gestão da informação e do conhecimento

This study analyzes the interrelations between the models of information literacy (IL), information management (IM) and knowledge management (KM). In order to do so, we, at first, highlight some concepts and definitions related to these terms, then we present some models applied to, so that we know the steps/stages of these recurring models. Finally, we present a comparative study between thestages/phases of models in IL, IM and KM, in order to check whether there are interrelations between the steps/phases of IL and the steps/stages of IM and KM. As a result we show the interrelations between the models, and assert that IL can act in an integrated manner to provide greater effectiveness to the informational processes of IM and KM. The analysis provides the expansion of IL contributions, reachingbeyond the scope of libraries and contributing to the development of this theme in the context of the contemporary society.

Estudo de dinâmicas populacionais aplicado a processos de tratamento biológico de efluentes

The purpose of this work is to perform studies of mathematical modeling of the relationship of interaction occurring between microrganisms participants from wastewater treatment processes aimed at understanding, through simulations, such as inter-relationships can affect the performance of such units. The methodology was the implementation in FORTRAN computer language of mathematical models of microbial interactions. The first model addresses the interaction of bacteria-forming flakes and filamentous bacteria in activated sludge systems, which seeks to strike a balance between these bacteria to improve efficiency of the process. Another model is studied the interaction between bacteria and protozoa in activated sludge systems and analyzing the efficiency of the process, observing the changes in daily load. Microbial interactions in anaerobic reactors were dealt a third model, in which there is the mutualistic interaction between acidogenic and methanogenic bacteria. In a fourth and final model was examined the relationship between the bacteria Acinetobacter sp. and Gordonia sp., which are present in activated sludge systems, showing the competitive capacity of Acinetobacter sp. can control the growth of unwanted bacteria.

The research aims to analyze the main changes in the concepts of the processes of production and consumption of news content information. The theoretical framework used will be the new consequent social, economic and technological paradigms of the current scenario of convergence of platforms, content and languages. The research aims to investigate the changes in the macro environment of journalistic production and, therefore, examine whether the local flow of news content meets the requirements of a new public consumption target set by the new Brazilian generations, composed of young people influenced by the cultures of computing, audiovisual communication and also by economic and cultural globalization. As expansion of the analyzes sought to verify the impact of these changes in the current models of traditional media, as well as the interference caused and trends in models of existing production. Also a case study is performed on this production flow in comparison with current market research of Jornal da Cidade (JC) of the city of Bauru (SP), the main media of the Grupo Comunicação. The intent of the approach will be to establish some preambles to assist in bringing the theory with the practical impacts on journalistic production, its agents, institutions and the workplace

A utilização de modelos matemáticos para a otimização de processos

This dissertation has as main theme the discuss about how the use of mathematical models for process optimization. The current scenario of strong competition to conquer the consumer market necessitates the development of improvements to better performance of the process as a whole, is to reduce costs, increase efficiency or effectiveness. Thus, the use of methodologies to assist in this process is becoming increasingly viable. Methodologies developed in the past are being studied and improved. An example is the Desirability, the object of the present study, which was developed in the 80's and has been improved over time. To understand and study this methodology was applied to the desirability function in three instances, where it was used Design of Experiments (DOE), taken from scientific papers, using the Solver tool (Excel ®) and desirability (Minitab ®). Thus, in addition to studying the methodology, it was possible to compare the performance of tools used for optimization in different situations. From the results of this study, it was possible to validate the superiority of one of the models studied compared fairly

Sistemas de filtragem aplicados em processos fabris automotivos

The present work resulted from a study about coolant filtration systems in industries with metalworking process in large scale. The filtration and element filter world markets move billions of Reais per year and have a promissory future considering that with the global requirements of sustainable economic development, many companies invest in new filtering technology. Either known as coolant or cutting fluid, it is used to lubricate e cool parts during machining and is necessary due to the high volume demanded in the several machining operations and to the high cost of the product. Therefore, there is the need for recycling the product after its use. The work shows the technology and fundamentals of filtration as well as different filtering elements, filtration systems and scale contamination used in the industry. Also, there is a differentiation between filtration of the surface type (cake) and depth filtration and shows the basic theory of filtration by mathematic models in different operational conditions. Ultimately, project criteria for a coolant filtration system selection is shown followed by technical-operational details of a real vacuum filtration system and a case study aiming the operational cost reduction of the system
