Criação e desenvolvimento do conhecimento organizacional com o auxílio da tecnologia de informação

In the last years, a number of enterprises ¿ each time greater ¿ have perceived the importance of the strategic management of the intellectual capital in its strategic planning. Factors like globalization of the economy and consequent awareness of specialized work value enclosed in organizational processes and routines, awareness of knowledge as factor of distinct production and low cost of data processing nets, point to a growing replacement of physical force for cerebral in our organizations and in our social lives. This work has the objective to analyze how the information technology, in its present stage, may contribute to creation and development of knowledge, or intellectual capital, in the organization of business. We will use for this purpose the methodology proposed by Nonaka and Takeuchi for creation of knowledge in the organizations. The model is based in two basic points: 1) the existence of two types of knowledge, the tacit and the explicit and its several processes of interaction wich generate operational knowledge (internalization), systematic knowledge (combination), shared knowledge (socialization) and conceptual knowledge (externalization); 2) the view that knowledge in principle is individual, belongs to each member of the organization and must be enlarged 'in an organization way'. Considering the characteristics of the methodology used, the proposal is the construction of a knowledge portal in the organization of business, so that it may be used as a tool for helping to create and develop organizational knowledge.

Participação de instituições locais em projetos de revitalização urbana : o caso do Projeto Porto Maravilha na cidade do Rio de Janeiro

Dentro do contexto do desenvolvimento urbano sustentável, diversas metrópoles estão revitalizando áreas centrais degradadas. Regiões portuárias são exemplos de áreas degradadas que têm passado por processos de revitalização. O envolvimento de diferentes atores locais (Poder Público, mercado e sociedade civil) no processo de decisão e também durante a implementação das obras de revitalização deve ser visto como ponto chave na garantia de um processo transparente e particular para cada revitalização executada. Para subsidiar tal abordagem, este trabalho utiliza como referencial teórico a gestão social e seus critérios do processo de discussão, pluralismo e bem-comum para a implementação de políticas públicas, onde a multiplicidade de atores deve participar em igualdade de direitos nos processos decisórios deliberativos na busca do bem-estar social. Na cidade do Rio de Janeiro, em 2009, a instituição por lei da Operação Urbana Consorciada da Área de Especial Interesse Urbanístico da Região Portuária do Rio de Janeiro garante que o projeto de revitalização chamado Porto Maravilha possa ser implementado. Por ser fruto de uma Operação Urbana Consorciada, o projeto deve contar com a participação de proprietários, moradores, usuários e dos investidores para revitalizar uma área de aproximadamente cinco milhões de metros quadrados. Assim, considerada a importância de diferentes atores para garantir um processo decisório legítimo e considerada a obrigatoriedade da participação de diferentes atores na implementação do projeto Porto Maravilha, o objetivo deste trabalho é identificar como as instituições locais participam no Projeto Porto Maravilha. Para tanto, realizou-se pesquisa de campo por meio da participação em reuniões das instâncias participativas na região portuária, da aplicação de questionários às instituições locais e da realização de entrevistas semiestruturadas com representantes das instituições locais e outros atores envolvidos com o projeto. Para o tratamento dos dados obtidos utilizou-se o método da análise de conteúdo com grade mista, cujas categorias definidas foram relacionadas com os critérios do processo de discussão, pluralismo e bem-comum da gestão social e um tratamento estatístico para a elaboração de uma matriz que permitiu relacionar o grau de participação e a posição das instituições locais frente ao projeto. Para o tratamento final, a triangulação metodológica foi utilizada e os resultados foram confrontados com o referencial teórico. Os resultados mostraram que a revitalização da região portuária despertou interesse para que instâncias participativas que já existiam na região se reestruturassem e que novas instâncias fossem criadas. Independente de serem a favor ou contra o projeto, há uma mobilização por parte das instituições locais em se envolverem no projeto, embora este não possa se caracterizar como um processo deliberativo de construção conjunta definido a partir de um consenso, pois, as diretrizes gerais do projeto Porto Maravilha foram instituídas por lei. A maioria das instituições locais concorda e participa do acompanhamento e da implementação do projeto por meio do compartilhamento com o Estado da responsabilidade de criar espaços educativos e investir em programas sociais que possam garantir a melhoria das condições de vida da população local.

Qualidade em obras públicas: um estudo comparativo entre as metodologias Seis Sigma, ISO 9000 e PBQP-H no RN

In Brazil the theme quality in public construction has been widely discussed in the early 1990s, with the creation of the Brazilian Program of Quality and Productivity for the Habitat (PBQP-H) which is strongly influenced by the wave of studies on issues of quality in the world, such as the ISO 9000. Over the years, other approaches have emerged and been consolidated, evolving from market and customer´s needs. An example is the Six Sigma methodology. This study aims to examine the Six Sigma, ISO 9000 and PBQP-H methodologies, noting the common elements, differences, gaps and how the methods are complementary, so that with the ongoing work, proposed initiatives can be developed to improve the quality that enables its application in public construction. Still aiming to optimize the deployment of the proposed initiatives, it was performed an analysis of ISO 9001 and PBPQ-H certifications in Brazil and in the state of Rio Grande do Norte, with respect to the construction industry and a case study to identify the factors that influence the adoption of initiatives to improve quality, and check if the selected construction company is prepared to implement the proposed initiatives. This research is characterized as exploratory and applied, with literature review and a case study. The data collection instrument was a questionnaire and the statistical analysis used a multidimensional scaling method. The conclusion is that the methodologies are compatible and complementary, and their integration could potentialize the goals set. It was identified that the state of Rio Grande do Norte has a few number of certifications in construction. Nine initiatives are proposed for implementation at construction companies. In the case study it was found that the studied company would be able to implement the suggestions proposed and the requirement for certification by clients and funding institutions influence the adoption of quality improvement initiatives. This result confirms the literature which states that top management support is crucial for the successful implementation of quality methodologies

Estudo da viabilidade da destilação solar para polimento de águas produzidas de petróleo

This work study of solar distillation feasibility in effluent of petroleum industry: produced water, making possible your reuse for irrigation of oleaginous cultures or fodder crops or in steam generation, as well the transport phenomena involved. The methodology for development of this project was to characterize the effluent to be treated and to accomplish physical and chemical analysis in the distilled, to build distillation equipment, concomitant operation of both equipments and implementation of data processing and economical evaluation. The methodology used for all parameters is outlined in APHA (1998) and sampling of the type compound. The feeding of distillation equipment was performed with treated effluent from UTPF of Guamaré. The temperature was monitored throughout the distillers and during the time of operation. The distillers feed occur, as a rule, for sifon. The distillers were operated by a period of 17 months between July 2007 and February 2009, in which 40 experiments were performed. The radiation and temperature datas were acquired in the INPE s site and the temperature inside of the distillers was registered by DATALOGGER Novus. The rates of condensation (mL / min) were determined by measuring of the flow in a graduate test tube of 10 mL and a chronometer. We used two simple solar effect distillers of passive type with different angles in coverage: 20 ° and 45 °. The results obtained in this study and the relevant discussions are divided into six topics: sample characterization and quality of distilled; construction of distillers; operation (data, temperature profile), climatic aspects, treatment of data and economical analysis. Results obtained can be inferred that: the energy loss by the adoption of vessel glass was not significant, however, complicates the logistics of maintenance the equipment on a large scale. In the other hand, the surface of the tub with a glass shield on the equipment deterioration, both devices showed similar performance, so there is not justified for use of equipment 450. With regard to the climatological study it was verified that the Natal city presents monthly medium radiation varying in a range between 350 and 600 W/m2, and medium of wind speed of 5 m / s. The medium humidity is around 70% and rainfall is very small. The regime of the system is transient and although it has been treated as a stationary system shows that the model accurately represents the distillers system's 20 degrees. The quality of the distilled with regard to the parameters evaluated in this study is consistent with the Class 3 waters of CONAMA (Resolution 357). Therefore we can conclude that solar distillation has viability for treat oilfield produced water when considered the technical and environmental aspects, although it is not economically viable

GDP 4.0 transfer to SGP 3.0 for SCIAMACHY no2 column processing: Verification with SDOAS / GDOAS prototype algorithms and delta-validation with NDACC / UV-visible network data

Until mid 2006, SCIAMACHY data processors for the operational retrieval of nitrogen dioxide (NO2) column data were based on the historical version 2 of the GOME Data Processor (GDP). On top of known problems inherent to GDP 2, ground-based validations of SCIAMACHY NO2 data revealed issues specific to SCIAMACHY, like a large cloud-dependent offset occurring at Northern latitudes. In 2006, the GDOAS prototype algorithm of the improved GDP version 4 was transferred to the off-line SCIAMACHY Ground Processor (SGP) version 3.0. In parallel, the calibration of SCIAMACHY radiometric data was upgraded. Before operational switch-on of SGP 3.0 and public release of upgraded SCIAMACHY NO2 data, we have investigated the accuracy of the algorithm transfer: (a) by checking the consistency of SGP 3.0 with prototype algorithms; and (b) by comparing SGP 3.0 NO2 data with ground-based observations reported by the WMO/GAW NDACC network of UV-visible DOAS/SAOZ spectrometers. This delta-validation study concludes that SGP 3.0 is a significant improvement with respect to the previous processor IPF 5.04. For three particular SCIAMACHY states, the study reveals unexplained features in the slant columns and air mass factors, although the quantitative impact on SGP 3.0 vertical columns is not significant.

Electrical consumers data clustering through optimum-path forest

Non-technical losses identification has been paramount in the last decade. Since we have datasets with hundreds of legal and illegal profiles, one may have a method to group data into subprofiles in order to minimize the search for consumers that cause great frauds. In this context, a electric power company may be interested in to go deeper a specific profile of illegal consumer. In this paper, we introduce the Optimum-Path Forest (OPF) clustering technique to this task, and we evaluate the behavior of a dataset provided by a brazilian electric power company with different values of an OPF parameter. © 2011 IEEE.

Implantação da ISO 9001:2008: estudo de caso em empresado setor de construção civil

In Brazil , the construction industry is on an upward trend, mainly by the housing shortage , and yet there are few builders that take a Quality Management System ( QMS ) to improve the quality of its services and processes . The ISO 9001 standards are guidelines for an effective QMS and this certificate is recognized worldwide as a seal of quality standard. This paper will describe and analyze the implementation of a QMS in a small construction company of Guaratinguetá - SP, identifying best practices and major difficulties , besides proposing preparatory recommendations for other companies that seek the ISO 9000 certification. Access to company’s data made the nonconformities and the customer satisfaction research analysis possible, and a questionnaire and unstructured interviews allowed a deeper understanding of the situation. Despite this ISO 9000 QMS not being fully implemented, the company has already conquered some improvements in document control, project planning, process traceability and established focus on customer

Práticas de gestão da melhoria contínua e aprendizado e suas contribuições para a capacidade de inovação na indústria de construção naval do Brasil

After years of stagnation, the naval construction industry in Brazil has been experiencing a period of recovery caused by investments in the oil and gas sector and the implementation of governmental programs that aimed to regenerate it. However, efforts in learning and innovations are needed in order to reinsert the country in this activity and achieve international levels of competitiveness. Based on literature about learning processes and continuous improvement practices and their impact in the innovative and productive processes, this paper aims to identify the main tendencies, mechanisms and procedures to improve the construction and management processes in the Brazilian naval construction industry. The methodology used for the data analysis classifies obtained information from magazines and annals of congresses of the sector, according to the established analysis categories (phenomena). Such categories study information related to the productive and technological processes of the industry, the main internal and external relations of the industrial park, the management of resources and processes, policies, investments, etc. The data was collected in the period 2004-2010, and more than 500 registers that show a dominance of the investment phenomenon, especially in the increase of productive capacity, were catalogued. In addition to this, there is evidence of modernization in the manufacturing plan and the equipment, diverse forms of cooperation, implementation of human resources management practices and engineering or processes and products. Hence, a process of catching up governs and is guided by modernization and increase training in this industry.

Gerenciamento de resíduos da construção civil: análise e atualização dos estudos realizados na UNESP-FEG para o município de Guaratinguetá

The construction industry is a large consumer of natural resources and one of the largest generators of residues with significant impacts on the environment. Because of the large production of Construction Industry Residues (RCC), it is essential reliable and updated information about generation, composition and classification sources of these residues, especially for management, recycling and final disposal. RCC represent the most part of solid residues generated in a city. In this way, the management of these residues is an issue that is gaining increasing importance in the Brazilian scenario, since the legal and society requirements to internalize the sustainability in the construction process - since the extraction, use, wastage savings, reutilization until the appropriate discard has been increasing in the last years. The present work objective is updating the quantities produced and collected in Guaratinguetá-SP, based on data collected with the municipal administrative entities that act direct or indirectly in the RCC management, elaborate a detailed bibliographic review, with special attention to the graduate works that were realized in FEG about this theme. With this material, scenarios to a better adequacy of the administrative structure to managements RCC activities, as well as was suggested actions to achieve these scenarios

High precision swept volume approximation with conservative error bounds

In technical design processes in the automotive industry, digital prototypes rapidly gain importance, because they allow for a detection of design errors in early development stages. The technical design process includes the computation of swept volumes for maintainability analysis and clearance checks. The swept volume is very useful, for example, to identify problem areas where a safety distance might not be kept. With the explicit construction of the swept volume an engineer gets evidence on how the shape of components that come too close have to be modified.rnIn this thesis a concept for the approximation of the outer boundary of a swept volume is developed. For safety reasons, it is essential that the approximation is conservative, i.e., that the swept volume is completely enclosed by the approximation. On the other hand, one wishes to approximate the swept volume as precisely as possible. In this work, we will show, that the one-sided Hausdorff distance is the adequate measure for the error of the approximation, when the intended usage is clearance checks, continuous collision detection and maintainability analysis in CAD. We present two implementations that apply the concept and generate a manifold triangle mesh that approximates the outer boundary of a swept volume. Both algorithms are two-phased: a sweeping phase which generates a conservative voxelization of the swept volume, and the actual mesh generation which is based on restricted Delaunay refinement. This approach ensures a high precision of the approximation while respecting conservativeness.rnThe benchmarks for our test are amongst others real world scenarios that come from the automotive industry.rnFurther, we introduce a method to relate parts of an already computed swept volume boundary to those triangles of the generator, that come closest during the sweep. We use this to verify as well as to colorize meshes resulting from our implementations.
