Correlação entre gestão da tecnologia e gestão ambiental nas empresas

Este trabalho analisa a correlação entre a gestão da tecnologia de produtos e processos e a gestão ambiental em empresas de manufatura. Partindo de um modelo conceitual simplificado e desdobramentos das dimensões gestão da tecnologia e gestão ambiental, foi possível analisar em pesquisa de campo vários conceitos disponíveis na literatura para esses dois campos, envolvendo 78 empresas do setor de manufaturados, através de projeto de pesquisa survey e projeto de pesquisa qualitativa. Visando avaliar a capabilidade tecnológica das organizações, foram usados os conceitos de microtecnologia e macrotecnologia relatados em Silva (2003). Concluiu-se que, dentro do campo pesquisado de empresas, existe correlação positiva entre os níveis de capabilidade tecnológica e os níveis de capabilidade ambiental.

Definição de requisitos de software baseada numa arquitetura de modelagem de negócios

Não é uma tarefa fácil definir requisitos para os sistemas de software que darão suporte a um negócio, dada a dinâmica de mudanças nos processos. O levantamento de requisitos tem sido feito de forma empírica, sem o apoio de métodos sistematizados que garantam o desenvolvimento baseado nos reais objetivos do negócio. A engenharia de software carece de métodos que tornem mais ordenadas e metódicas as etapas de modelagem de negócios e de levantamento de requisitos de um sistema. Neste artigo é apresentada uma metodologia de desenvolvimento de software resultante da incorporação de atividades propostas para modelagem de negócios e levantamento de requisitos, baseadas em uma arquitetura de modelagem de negócios. Essas atividades tornam o desenvolvimento de software mais sistemático e alinhado aos objetivos da organização, e podem ser incorporadas em qualquer metodologia de desenvolvimento baseada no UP (Unified Process - Processo Unificado).

Avaliação de painéis produzidos a partir de resíduos sólidos para aplicação na arquitetura

O presente trabalho tem por objetivo o reaproveitamento de resíduos sólidos na preparação de painéis para uso na arquitetura. Para atingir as metas propostas, painéis foram preparados a partir de resíduos provenientes de embalagens cartonadas e plásticas, utilizando-se como elemento de reforço, resíduos lignocelulósicos (casca de amendoim e de arroz). A concentração e a natureza dos resíduos utilizados como matriz e como carga foram variadas gerando doze condições experimentais diferentes. As propriedades avaliadas dos painéis foram o módulo de ruptura, módulo de elasticidade, tração perpendicular à superfície, inchamento em espessura, absorção de água e densidade. Todos os ensaios foram realizados segundo as normas ASTM D1037 e EN 317, referente à chapa de partículas. Os resultados foram analisados segundo a norma ANSI A208.1 que especifica as propriedades de desempenho requeridas para as chapas de partículas. Os painéis foram classificados como de baixa densidade, podendo ser utilizados como forros, divisórias, revestimento decorativos e demais aplicações que requerem as mesmas propriedades físicas e mecânicas. Os painéis a base de embalagem plástica reforçados com casca de arroz apresentaram propriedades superiores do que os demais painéis produzidos. O elemento arquitetônico desenvolvido neste estudo representa um novo mercado potencial, podendo ser empregado no ambiente urbano e rural, atendendo ao conceito de produto ecoeficiente.

Estruturas, arquitetura e evolucao do Complexo Granitoide Itaqui (SP)

The Itaqui Granitoid Complex is a drop shaped WNW-ESE trending intrusion with its head' at west. Its contacts with the low-grade metamorphic rocks of the Sao Roque Group are intrusive at west, northwest, north and northeast, and tectonic at south and northeast. The complex is built up by four main intrusive phases which characterize a rising and unroofing process. Petrographically the Itaqui granite comprises five distinct magmatic associations in nine igneous units. -from English summary

Sinterização de uma mistura de cavaco de aço inoxidável com pó do mesmo material. Uma nova tecnologia para a reciclagem de metais?

The reuse of materials has as its main objective to minimize environmental impacts and to rationalize the use of energy chains. In the present work, samples of scraps of 316 stainless steel mixed with powder of the same material were sintered. For this case, the percentage of scrap was varied from zero to 25% in weight, with 5% increases. After compacting, under a pressure of 600MPa, the samples were sintered simultaneously at a temperature of 1473 K. The mechanical behavior of the final product was evaluated through Assays of Transversal Rupture recommended and normalized by the MPIF - Metal Powder Industries Federation. Using Conventional Quantitative Metallography, the analyses of the sintered samples demonstrated regions of intense diffusion, therefore, regions of sufficiently intense sintering. The mechanical resistance of the samples was compared with the mechanical resistance of the sintered stainless steel with no scrap. The results were greater than expected, demonstrating the viability of this new procedure.

Telefonoaudiologia: Ciência e tecnologia em saúde

Background: distance learning (DL) is becoming a higher education modality with a meaningful impact. It offers students flexibility, mobility and choices. Also it can reach a greater number of professionals and students in a more effective way, when compared to other learning modalities, without losing quality. Brazil needs to develop direct actions to DL in the fields of Speech-Language Pathology and Hearing, due to its great continental territory (8,514,215.3Km 2) and irregular distribution of professionals who work in these specific fields (i.e. this situation emphasizes the differences in quality and availability of services offered throughout the country). Heterogeneity in the quality and availability of services is also aggravated by the absence of a national strategy for continued education in order to recycle health professionals. This situation causes important differences in the knowledge and abilities of specialists from one region to the next. Aim: to present Telehealth studies in the field of Speech-Language Pathology and Hearing that were developed in the last five years. Conclusion: the analyzed data indicate that more studies are needed in this specific field. These studies should aim at improving the quality and access to services which in turn would improve prevention, diagnosis and treatment of communication disorders.

Arquitetura da parede vascular de segmentos torácico e abdominais da aorta de macaco prego (Cebus apella)

The intimal layer of the thoracic and abdominal aortic segments of Cebus apella monkey presented an evident inner elastic lamina. The medial layer of the thoracic aorta segment showed a basic lamellar elastic pattern having a medium average of 23.12 lamellae per analyzed cut sections, which appeared disposed circular and oblique relatively to the aortic lumen. The aortic adventitial layer, at this level, was formed mainly by collagen fibers, irregularly disposed between elastic fibers and smooth muscle cells. The aortic abdominal portion, in this monkey, at the suprarenal level presented a medium number of 19.12 elastic lamellae which showed a relatively disorganized and broken up pattern. At the infrarenal level the aortic medium layer showed a medium average of 11.75 elastic lamellae and next to the emission of the internal iliac arteries it was found only a middle average of 8.37 elastic lamellae intermingled with smooth muscle cells and collagen fibers whose concentration seemed to be increased next to the adventitial layer. The external elastic lamina was only present in the more distal aortic segment near to the emission of the internal iliac arteries.

Diagnóstico das áreas de preservação permanente na bacia hidrográfica do rio Tijuco, Ituiutaba - MG, utilizando tecnologia SIG

The present work had the objective to elaborate the map of land use and vegetation covering from Tijuco river watershed, Ituiutaba-MG, based on digital images obtained by satellite from CBERS 2, through automatic delimitation of permanent preservation areas followed by identification of land use conflict based on the Brazilian Forest Code (Law no 4771/1965) and National Council of Environment's Resolution no 303/02. This paper analyzes, through quantitative parameters and the use of Geographic Information System, the maintenance tracks of width recommended by the legislation for permanent preservation areas over water bodies. The results showed a deficit of conserved areas along the riverbanks of 2334 ha that are not in compliance with the legislation. The pasture occupies unduly 0.97% of the area of the basin in the permanent preservation areas at the riverbanks, while agriculture occupies 0.38%.

Adoção da tecnologia da informação em organizações rurais: O caso da pecuária de corte

Adoption of technology. Farm management. Beef cattle breeding. Information technology.This research is aimed to study the use and the diffusion of IT in the beef cattle breeding from the analysis of the factors that have influenced its adoption as well as to describe resources, procedures, and necessary actions for IT operation using case studies in rural properties classified by the innovativeness degree. This study was carried out in two stages, quantitative and qualitative. In the first stage, a survey with producers was conducted. Information concerning the different technologies adopted enabled to identify the level of innovativeness of those producers. They were classified according to the similarities of the technological position. The second stage analyzed experiences, opinions, and perspectives regarding the technology integrated to the productive system. Two rural cattle breeding farms were analyzed in each category through personal interviews totalizing ten case studies. The results indicated the reasons for the adoption or rejection of a certain IT by the producers allowing for the identification of the reasons why some producers have adopted it more quickly than others. It was possible to understand the rural organization modifications due to IT adoption, for example, managerial skills improvements. In general, the processes have been improved and become easier bringing positive effects to several areas including human resources and the enterprise's image in the market.

O projeto para o pavilhão brasileiro na expo' 92 em sevilha e a chamada arquitetura paulista

This article discusses the controversy surrounding the winning project of the competition organized by the Brazilian Ministry of Foreign Affairs for the Brazilian pavilion at the Expo'92 in Seville, Spain; the views of architecture critics made at the time of the results, and, their implications for Brazilian architecture. At the beginning of the 90s, this competition was a kind of confrontation of ideas, between the architects who were in favour of a renewal of architecture and those who defended the resumption of national architectural traditions, buildings with large spans, constructed in reinforced concrete. These architects were the heirs of the so called Paulista architecture, which was characterised by the work undertaken from the 60's by important architects such as Vilanova Artigas and Paulo Mendes da Rocha. The modern references adopted by the winning project, from the architects Angelo Bucci, Alvaro Puntoni and José Oswaldo Vilela, sparked controversies because of the difficulty of resuming the teachings of the old modern masters when faced with new times. These controversies were related to the end of the military dictatorship in Brazil and the process of opening markets, and by the relevance of a re-evaluation of the so-called Paulista architecture.
