Abstract: The health education has been a topic discussed throughout Brazil, as the country is experiencing a period of expansion of higher education and it needs to give quality. So they were implanted two federal programs to allow that health students to approach their professional reality to make them capable of full mode. The paper aims to discuss the experience of the participating members of these programs for professional reorientation. The study is exploratory and descriptive conducted with participants of the programs in the city of Santa Cruz, Rio Grande do Norte, Brazil, in the year 2014. This study aims to present an experience report from the experience of the mentors in Reorientation National Program for Health Professional Training (Pró-Saúde), associated with the Labor Education Program for Health (PET-Saúde) at the Federal University of Rio Grande do Norte (UFRN)/Sciences College of Trairi (FACISA), with emphasis on the reorientation of professional practice, provided by integrating teaching-service and community as well as exchange of knowledge between tutors, mentors and students participating in the project, from the development of interdisciplinary activities, giving the opportunity to reflect on these actions and services offered based on the epidemiological analysis provided by research, intervening in this reality.
Structuring reflective middleware using meta-information management: the Meta-ORB approach and prototypes
Costa, Fábio M.;Santos, Bruno da Silva;
Journal of the Brazilian Computer Society , 2004, DOI: 10.1007/BF03192353
Abstract: reflection is now an established technique for achieving dynamic adaptability of middleware platforms. it provides a clean and comprehensive way to access the internals ofa platform implementation, allowing its customisation in order to achieve the best performance and adequacy under given operation environments and user requirements. in addition, the use ofa runtime component model for the design ofthe internal platform structure facilitates the identification of the elements to be adapted, as all platform aspects are built in terms ofcomponents. the major limitation ofthis approach, however, is related to the multitude ofaspects that make up a middleware platform, together with the requirement ofkeeping platform consis-tencyafter adaptations take place. this paper presents the results of ongoing research contributing to reduce this limitation. the approach is based on the use ofa common meta-model, together with meta-information techniques to provide a uniform way to specify and manipulate platform configurations. both platform configuration and runtime adaptation are always specified using a small number of building blocks defined in the meta-model. the paper also describes the overall architecture ofthe meta-orb platform, which demonstrates this approach, and presents its two implementations: a proof-of-concept prototype written in python, and a java-based implementation aimed at supporting mobile devices. the results are also evaluated from a quantitative perspective, according to the requirements ofmultimedia applications, one ofthe major areas of application of reflective middleware.
