Desenvolvimento de um modelo de gestão do conhecimento para a melhoria do processo de desenvolvimento de produtos

The knowledge management has received major attention from product designers because many of the activities within this process have to be creative and, therefore, they depend basically on the knowledge of the people who are involved in the process. Moreover, Product Development Process (PDP) is one of the activities in which knowledge management manifests in the most critical form once it had the intense application of the knowledge. As a consequence, this thesis analyzes the knowledge management aiming to improve the PDP and it also proposes a theoretical model of knowledge management. This model uses five steps (creation, maintenance, dissemination, utilization and discard) through the verification of the occurrence of four types of knowledge conversion (socialization, externalization, combination and internalization) that it will improve the knowledge management in this process. The intellectual capital in Small and Medium Enterprises (SMEs) managed efficiently and with the participation of all employees has become the mechanism of the creation and transference processes of knowledge, supporting and, consequently, improving the PDP. The expected results are an effective and efficient application of the proposed model for the creation of the knowledge base within an organization (organizational memory) aiming a better performance of the PDP. In this way, it was carried out an extensive analysis of the knowledge management (instrument of qualitative and subjective evaluation) within the Design department of a Brazilian company (SEBRAE/RN). This analysis aimed to know the state-of-the-art of the Design department regarding the use of knowledge management. This step was important in order to evaluate in the level of the evolution of the department related to the practical use of knowledge management before implementing the proposed theoretical model and its methodology. At the end of this work, based on the results of the diagnosis, a knowledge management system is suggested to facilitate the knowledge sharing within the organization, in order words, the Design department

CREATION: técnica de criatividade para geração de ideias de novos produtos

Creativity is a skill found in all individuals and one of the strategies used to intensify it is through the application of creativity techniques. In order to propose a new technique for generating new crafts product ideas, this dissertation, which is part of a research project of the Federal University of Rio Grande do Norte, through action research, intervened in three state communities artisans - Lajes Pintada, Massaranduba and Vera Cruz - to develop the artisans creative potential. Based on the techniques studied in the literature, we selected three techniques for interventions, composing two dynamics - one to improve features and functionalities of existing products, with the technique of SCAMPER; and the other to generate ideas for creating new products, with techniques Listing and Random Words / Figures. These latter techniques were not satisfactory in its objective by presenting constraints, not covered in the description, for the participant group. Thus, it was necessary to propose a new technique for the same purpose, the technique CREATION Clarify technique, Realized creativity, Explain, Apply for word, Think fast, Interpret, Organize ideas, Now evaluate, composed of twelve steps. To use the new technique requires that it be used by a dynamic that takes into account three phases: Planning, Application and Analysis. In the new technique application were generated around 30 ideas, regarded as new, in six sessions, from test pilot to interventions in artisans communities

Estratégia de marketing ambiental no varejo de alimentos: um estudo sobre as variáveis utilizadas pelo consumidor na decisão de compra de produtos orgânicos

Demand for organic foods within in Brazil are growing, characterizing itself for if constituting in a new strategical segment of commercialization. In this context, the objective of this research was to investigate the variables used by consumers in the purchase decision of organic products, aiming to characterize the level of competitiveness of these products, assisting in the creation of environmental strategies for the development of the activity and contributing in the increment of the knowledge about the subject, that can assist it in the increase of the commercialization and the consumption of these foods. From data collected in the city of Natal/RN, it was used a survey research, of exploratory and descriptive character. The sample was obtained using 401 questionnaires, in which was realized: the Test of Comparison of Averages, Descriptive analysis, analysis of Cluster and Qui-square. The results found in this study indicate that the main reasons for the organic food purchase are the absence of chemical pesticides in the product, followed by the care with own health and of the household. The main characteristics in the consumers of supermarkets, that are associates with purchase frequency of organic foods are the environmental behavior and lifestyle. Among the profile characteristics, gender, age and number of children are associates with the purchase frequency of these foods and the income and level education not showed association

Gestão ambiental e competitividade: um estudo sobre os fatores que afetam a decisão de compra de produtos orgânicos na cidade de Teresina-PI

The organic products represent one of the main trends of alimentary consumption in the new century. In Brazil, the answer is already well representative which it becomes the country, as a great consuming and exporting market of products of LVF type. The objective of this research was to investigate the factors capable to influence the food consumer in its purchase decision of organic products in the supermarkets of Teresina, capital of Piauí State. The methodology was exploratory and descriptive, using survey, with closed and opened questions in 542 interviewed. The questionnaire was based on projected scales to evaluate the factors that can influence the purchase decision of organic products, whose variable had been grouped in the following groups: behavior, knowledge, interest, competitiveness, importance, barrier and profile. The used statistical techniques were descriptive analysis and multiple regression analysis. The results demonstrate interest of the population in paying more for the organic product, due to better quality of life, however it lacks to one better spreading and greater sensitization to attract these consumers. Some recommendations and proposals are presented after the results, as suggestions for future research

Curvas de crescimento e de deposição dos componentes corporais em aves de postura de diferentes linhagens

Objetivou-se com este trabalho determinar as curvas de crescimento de aves de postura das linhagens semipesadas Hy Line Marrom (HLM) e Hisex Marrom (HSM) e leves Hy Line W36 (HLW36) e Hisex Branca (HSB). Foram utilizadas 300 aves de cada linhagem, distribuídas em um delineamento experimental inteiramente casualizado, com quatro repetições de 75 aves por tratamento. Semanalmente, foram avaliados o peso vivo (PV), o peso de pena (PP) e a composição corporal de proteína, gordura, cinzas e água. As curvas de crescimento foram determinadas aplicando-se os dados na função de Gompertz. As aves semipesadas foram mais tardias para PV que as leves, com taxas de crescimento corporal e pesos à maturidade (PM) maiores. Aves da linhagem HLW36 foram 64,23 g mais leves à maturidade que as HSB. As respostas obtidas para o crescimento das penas e deposição protéica foram semelhantes, todavia, os PM foram maiores para as aves marrons que para as brancas. No entanto, para estes componentes, as Hy Line tiveram maiores deposições que as Hisex. A taxa de peso de pena à maturidade foi menor na linhagem HLW36, tornando-a três dias mais tardia em comparação à HSB. A menor deposição protéica no final do período de crescimento da HSM possibilitou o desvio da energia ingerida para deposição de gordura, resultando em PM superestimado em relação às aves HLM. As aves da linhagem Hy Line foram mais tardias na composição de cinzas, apresentando PM superiores ao das aves Hisex. Entre as variáveis estudadas, os PM foram sempre maiores nas aves Hy Line, no entanto, a deposição de água corporal nas aves Hisex foi maior, assim como as taxas máximas à maturidade foram mais tardias, o que justifica a semelhança no ganho de peso entre as diferentes linhagens, visto que os demais componentes estudados foram maiores para as Hy Line.

Uma arquitetura de software baseada em componentes visualização de informações industriais

Due to the current need of the industry to integrate data of the beginning of production originating from of several sources and of transforming them in useful information for sockets of decisions, a search exists every time larger for systems of visualization of information that come to collaborate with that functionality. On the other hand, a common practice nowadays, due to the high competitiveness of the market, it is the development of industrial systems that possess characteristics of modularity, distribution, flexibility, scalability, adaptation, interoperability, reusability and access through web. Those characteristics provide an extra agility and a larger easiness in adapting to the frequent changes of demand of the market. Based on the arguments exposed above, this work consists of specifying a component-based architecture, with the respective development of a system based on that architecture, for the visualization of industrial data. The system was conceived to be capable to supply on-line information and, optionally, historical information of variables originating from of the beginning of production. In this work it is shown that the component-based architecture developed possesses the necessary requirements for the obtaining of a system robust, reliable and of easy maintenance, being, like this, in agreement with the industrial needs. The use of that architecture allows although components can be added, removed or updated in time of execution, through a manager of components through web, still activating more the adaptation process and updating of the system

Estimação de componentes de co-variância para pesos corporais do nascimento aos 365 dias de idade de bovinos Guzerá empregando-se modelos de regressão aleatória

Um total de 19.770 pesos corporais de bovinos Guzerá, do nascimento aos 365 dias de idade, pertencentes ao banco de dados da Associação Brasileira dos Criadores de Zebu (ABCZ) foi analisado com os objetivos de comparar diferentes estruturas de variâncias residuais, considerando 1, 18, 28 e 53 classes residuais e funções de variância de ordens quadrática a quíntica; e estimar funções de co-variância de diferentes ordens para os efeitos genético aditivo direto, genético materno, de ambiente permanente de animal e de mãe e parâmetros genéticos para os pesos corporais usando modelos de regressão aleatória. Os efeitos aleatórios foram modelados por regressões polinomiais em escala de Legendre com ordens variando de linear a quártica. Os modelos foram comparados pelo teste de razão de verossimilhança e pelos critérios de Informação de Akaike e de Informação Bayesiano de Schwarz. O modelo com 18 classes heterogêneas foi o que melhor se ajustou às variâncias residuais, de acordo com os testes estatísticos, porém, o modelo com função de variância de quinta ordem também mostrou-se apropriado. Os valores de herdabilidade direta estimados foram maiores que os encontrados na literatura, variando de 0,04 a 0,53, mas seguiram a mesma tendência dos estimados pelas análises unicaracterísticas. A seleção para peso em qualquer idade melhoraria o peso em todas as idades no intervalo estudado.
