This paper presents the development of an multi-projection stereoscopic dental arches application with semantic descriptions. The first section presents the concepts of the used technologies. Applications and examples are demonstrated. Finally, is presented the physical structure and the developed system, where a 3D dental arch is used as a model and can be viewed in multi-projection, thereby, providing greater user's immersion. ©2010 IEEE.

In the book Conceptual Spaces: the Geometry of Thought [2000] Peter Gärdenfors proposes a new framework for cognitive science. Complementary to symbolic and subsymbolic [connectionist] descriptions, conceptual spaces are semantic structures constructed from empirical data representing the universe of mental states. We argue that Gärdenfors' modeling can be used in consciousness research to describe the phenomenal conscious world, its elements and their intrinsic relations. The conceptual space approach affords the construction of a universal state space of human consciousness, where all possible kinds of human conscious states could be mapped. Starting from this approach, we discuss the inclusion of feelings and emotions in conceptual spaces, and their relation to perceptual and cognitive states. Current debate on integration of affect/emotion and perception/cognition allows three possible descriptive alternatives: emotion resulting from basic cognition; cognition resulting from basic emotion, and both as relatively independent functions integrated by brain mechanisms. Finding a solution for this issue is an important step in any attempt of successful modeling of natural or artificial consciousness. After making a brief review of proposals in this area, we summarize the essentials of a new model of consciousness based on neuro-astroglial interactions. © 2011 World Scientific Publishing Company.

Cartography is one of the languages that express the knowledge of the geographic space and, therefore, the official curriculum proposals have highlighted the importance of the geography teaching which articulates its contents with this language in primary education. So, we present an analysis of the content selected to the curriculum mapping specifications of the São Paulo faz escola material, specifically for the 6th year of Elementary School II, version 2009. From the perspective of qualitative research, with instruments and techniques of quantitative and qualitative research, we analyzed documents and observed little concern with the proposition works that present the physical and social characteristics of the state of São Paulo. Also, we noticed the lack of concern with representations in local and regional scales. The research brings many examples on the global scale. It explores few activities using graphics and charts. Despite bringing thematic maps in their entirety, it does not show an example of conical projection as well as cartograms and anamorphosis. Furthermore, the trend of a technicist education is announced in the document
