Integração do framework manakin com a plataforma dspace para múltiplas apresentações visuais de informações nos repositórios digitais

Digital repositories are currently being used by education and research institutions in Brazil as an alternative for propagating scientific and academic results, mainly to reach institutional memory and visibility. However, the way these results are presented may influence their use, affecting user-system interaction through the interface components. Thus, it is possible to state that an unique digital information environment can offer different ways of visual presentation, customizing informational and visual components for specific users communities. In this context, tools are being developed as a resource to make access and use of information easier, and to increase the usability of digital informational environments. One of these tools, Manakin, is presented in this paper, as well as its integration with the DSpace platform, in order to enable multiple visual presentations, stressing the importance of the differentiation and direction of interfaces by a single repository to the various knowledge fields. So, results and examples of repositories with multiple visual presentations are introduced, to facilitate the use of the presented tool, as well as to reinforce the importance of a differentiated visual identity by areas of knowledge in a single repository, by means of literary and exploratory analysis.

Realidade misturada: conceitos, ferramentas e aplicações

The Mixed Reality proposes scenes combining between virtual and real worlds offering to the user an intuitive way of interaction according to a specific application. This tutorial paper aims at presenting the fundamentals concepts of this emergent kind of human-computer interface.

Environmental management system and human resource practices: is there a link between them in four Brazilian companies?

The aim of this article is to analyze the theoretical model proposed by [Jabbour CJC, Santos FCA. Relationships between human resource dimensions and environmental management in companies: proposal of a model. Journal of Cleaner Production 2008;16(1):5 1-8.] based on the data collected in four Brazilian companies. This model investigates how the phases of the environmental management system can be linked to human resource practices in order to attain continuous improvement of a company's environmental performance. Our aim is to contribute to a field, which has little empirical evidence. Although the interaction between the phases of the environmental management system and human resource practices is recommended by the specialized literature [Daily BE Huang S. Achieving sustainability through attention to human resource factors in environmental management. International Journal of Operations and Production Management 2001:21(12):1539-52.], the results indicate that most of the theoretical assumptions could not be confirmed in these Brazilian companies.

Human pulp response after an adhesive system application in deep cavities

Objectives: To evaluate the pulpo-dentin complex response to a dentin adhesive application in deep cavities performed in human teeth.Methods: Deep class V cavities were prepared on the buccal surface of 46 premolars. The remaining dentin of the axial wall received 10% phosphoric acid and dentin adhesive (group DA), or was protected before the acid and dentin adhesive application with calcium hydroxide cement (group CH). Half of the teeth, which received the acid application directly over the axial wall, were contaminated prior to the procedures with dental plaque collected from the patient's own teeth (group DAC). The plaque was placed on the dentin for 5 min and then the cavity was washed. All teeth were restored with a light-cured composite resin. The teeth were extracted after 7, 30 or 60 days and prepared according to normal histologic techniques. Serial sections were stained with WE, Masson's trichrome and Brown & Brenn technique for demonstration of bacteria.Results: the histopathologic evaluation showed that in groups DA and DAC, the inflammatory response was more evident than in group CH. Also, the intensity of the pulp reaction increased as the remaining dentin thickness decreased. There was no statistical difference in the inflammatory response between the groups DA and DAC.Conclusion: Based on the experimental conditions, we concluded that the All Bond 2 adhesive system, when applied on dentin in deep cavities, showed an acceptable biocompatibility. However, the intensity of the pulpo-dentin complex response depends on the remaining dentin thickness. (C) 1999 Elsevier B.V. Ltd. All rights reserved.
