O sertão literário na contemporaneidade: Guimarães Rosa e Ronaldo Correia de Brito

The text analyses the way in which regionalism, centered in the representation of social and human relations and related to universalism, has been applied to Guimarães Rosa and the way in which it appears nowadays in the work of Ronaldo Correia de Brito. This aim is pursued by means of reflections on the survival of the expression regionalism, its application to the work of Guimarães Rosa – especially in one composition of Tutameia – and its contemporary reappearance in a short story by Correia de Brito.

A Low Cost Controller Board for Teaching Robotics

This paper presents the Smarty Board; a new micro-controller board designed specifically for the robotics teaching needs of Australian schools. The primary motivation for this work was the lack of commercially available and cheap controller boards that would have all their components including interfaces on a single board. Having a single board simplifies the construction of programmable robots that can be used as platforms for teaching and learning robotics. Reducing the cost of the board as much as possible was one of the main design objectives. The target user groups for this device are the secondary and tertiary students, and hobbyists. Previous studies have shown that equipment cost is one of the major obstacles for teaching robotics in Australia. The new controller board was demonstrated at high-school seminars. In these demonstrations the new controller board was used for controlling two robots that we built. These robots are available as kits. Given the strong demand from high-school teachers, new kits will be developed for the next robotic Olympiad to be held in Australia in 2006.
