O presente trabalho teve como principal objetivo o estudo das diferenças entre os resultados obtidos com o uso do método dos mínimos quadrados ponderados e de mínimos quadrados ordinários, no ajuste do modelo de Orskov e McDonald (1979) aos dados de degradação da matéria seca (MS) e fibra em detergente ácido (FDA) em novilhos Nelore fistulados, utilizando a técnica in situ. Foram utilizados os dados de um experimento delineado em quadrado latino 4x4 (quatro animais e quatro períodos) cujos tratamentos foram: dieta com sal de cálcio de ácidos graxos e monensina (A); dieta com caroço de algodão e monensina (B); dieta controle com monensina (C) e dieta com caroço de algodão sem monensina (D). As medidas de degradabilidade foram coletadas em oito ocasiões (0, 3, 6, 12, 24, 48, 72 e 96 horas). Como essas medidas são obtidas repetidamente no mesmo animal, espera-se que as variâncias das respostas nas diversas ocasiões não sejam iguais. Nas análises propostas foram utilizados os dados originais (MS e FDA) e os dados corrigidos para os efeitos de animal e de período. De uma forma geral, observou-se que o uso do método dos mínimos quadrados ponderados alterou os resultados das análises, produzindo um aumento das estatísticas dos testes e uma alteração da significância dessas estatísticas, por conta da retirada do efeito de animal e período dos dados originais e ao uso do método de mínimos quadrados ponderados, com a ponderação feita pelo inverso da variância dos dados em cada ocasião. / The present work had as main objective the study of the differences between the results obtained using the method of the weighted least squares and ordinary least squares, in the fit of the model of Orskov and McDonald (1979) to the data of degradation of the dry matter (MS) and acid detergent fiber (ADF) in fistulated Nelore steers, using the technique in situ. The data of a delineated 4x4 Latin Square had been used (four animals and four periods) whose treatments had been: diet with calcium salt of fatty acid and monensin (A); diet with whole cottonseed and monensin (B); diet has control with monensin (C) and diet with whole cottonseed without monensin (D). The measures of degradability had been collected in eight occasions (0, 3, 6, 12, 24, 48, 72 and 96 hours). As these measures they are gotten repeatedly in the same animal, expects that the variances of the answers in the diverse occasions are not equal. In the analyses proposals the original data (MS and ADF) and the data corrected for the period and animal effect had been used. Of a general form, it was observed that the use of the method of the weighted least squares modified the results of the analyses, producing an increase of the statisticians of the tests and an alteration of the significance of these statisticians, for account of the withdrawal of the animal effect and period of the original data and to the use of the method of weighted least squares, with the weighted made for the inverse one of the variance of the given ones in each occasion.

Esse trabalho partiu da reflexão sobre interfaces gráficas sofisticadas e pouco intuitivas e o impacto das mesmas na modelagem tridimensional. A partir dessa reflexão, a pesquisa foi direcionada para o estudo de interfaces gestuais. Adotou-se, como foco do estudo, a técnica de geração de modelos tridimensionais, chamada origami por seu caráter exploratório, sistemático e sua aproximação com a área da matemática, engenharia, arquitetura e design. O problema de pesquisa consistia em identificar padrões de gestos da mão e diretrizes para uma interface gestual voltada à construção de modelos tridimensionais, a partir das técnicas de origami. A pesquisa buscou fundamentação na bibliografia e na análise sistemática de vídeos de modelagem física referentes aos movimentos da mão e ao comportamento dos modelos. Com os dados levantados foram gerados esquema e gráficos para análise. Os dados gerados auxiliaram na seleção de um vocabulário de gestos e de diretrizes para interface e comportamento dos modelos no ambiente digital que passaram por testes de aplicabilidade no ambiente físico. Os resultados gerados visaram direcionar para desenvolvedores de softwares sobre as principais características da modelagem de origami no meio digital com utilização de interface gestual. / This work was based on the consideration of sophisticated and somewhat intuitive graphical interfaces and their impact on three-dimensional modeling. Based on this discussion, the research is directed towards the gestural interfaces studies. It was adopted, as the focus of study, the threedimensional models generating technique, called origami. Because of his approach to the mathematics, engineering, architecture and design field and his exploratory and systematic characteristic. The research problem was to identify gestures hand patterns and guidelines for a gestural interface focused on building three-dimensional models, from the origami techniques. The work sought, justification in the literature and systematic analysis of physical modeling video related to hand movements and models behavior. With the collected data, graphics and analysis scheme were generated. The generated data helped in the selection of a gestures vocabulary and guidelines for interface and behavior of the models in the digital environment. Those were submitted on applicability tests in the physical environment. The results generated, aims give some directions for developers of software about the main features of the origami modeling in digital media using gestural interface.

DEVELOPMENT AND RESEARCH OF SPECIAL LUMINAIRE SYSTEMS Relevance of the research When Lithuania were joined into the European Community it has become necessary to use lighting devices corresponding to requirements of the European Community – ENEC norms. Taking into account the specificity of given devices in Lithuania and other new EU countries they should be steady against low temperatures, humidity, acts of vandalism, to be suitable for the illumination of industrial buildings and to fulfil the requirements of low prices of the new incorporated countries. Recently new comprehensive ENEC norms (EN European Norms, EC Electrical Certification) for luminaires were drawn up and effectively introduced by the European Union. As a result, the production of a wide range of electrical operating equipment was discontinued due to the inconsistency between technical parameters of produced equipment and new norms. Such equipments were not allowed to be marketed. Therefore it has become necessary to develop luminaires capable to fulfil the increased quality requirements of the European Union. Their development should also taken into account due to the targets of product responsibility (§ 22) laid down in the Act for Promoting Closed Substance Cycle Waste Management and Ensuring Environmentally Compatible Waste Disposal introduced in 1996 also should be taken into account extensively the aspects of ecological efficiency. In the past, plastic luminaire systems belonging to a higher... [to full text]

The purpose of this study was to to examine what teachers think about visual art and how the learning process in this subject does look like. To answer these issues, I made interviews with five teachers of visual art from different schools, and I examined several examples of pupils’ artworks. The stories of the teachers were analyzed in relation to governing documents and with assumptions from sociocultural theory, postmodernism and pedagogical - aesthetic research as theoretical point of view. By the qualitative interview method, the observations of the pupil’s artworks, and by the analysis of the interviews with the teachers, I have come to the conclusion that teachers think differently about art but they try to keep themselves in line with the national governing documents. Its affects aspects of disciplines, styles, techniques and medium that is exemplified by the pupil’s art works, and it points out similarities and differences between the pupil’s art works and between the teachers when teaching visual art.
