Ensino colaborativo e educação física: contribuições à inclusão escolar

In Brazil, special education public is a challenge to all teachers, especially to Physical Education ones. Among others, it encompasses students with disabilities, students with intellectual giftedness, and students with pervasive developmental disorder. Besides posing challenges, the inclusion process causes worry and generates debates on problems that impede the full partaking of such pupils in schooling practices related to physical education. This thesis presents a research that focused on these matters by means of co-working involving the researcher and the Physical Education teacher in regular classrooms following co-teaching perspective. The starting point of the research is the following question: what contributions co-working involving Physical Education teacher and researcher may provide to people with disabilities and to Physical Education teacher in regular schools attended by students who are the special education’s target? The research aimed at discussing and analyzing the development of such co-working activity involving the researcher and Physical Education teacher. It followed co-teaching perspective and was put into practice in a public school in Uberlândia, state of Minas Gerais. Participant qualitative approach, which recognizes relations between social sciences and intervention in social reality, was the methodological choice to develop the research in three phases: 1) making the research; 2) intervening in social reality; 3) assessing/diagnosing it. Strategies to gather data included semi structured interview, questionnaire, participant observation, and group interview. Data come, above all, from oral accounts as well as from the work by the group of participants of the research, which means, researcher, Physical Education teacher who works at regular schools and three teachers who deal with AEE (Atendimento Educacional Especial), a special educational teaching program. The concept of inclusion is discussed accordingly to authors such as Miranda (2001), Mantoan (2001), Duarte and Santos (2003), Mittler (2003), Rodrigues (2006), and Bueno (2008). The conception of co-working is developed in the light of studies by Capellini (2004) and Mendes (2009), among others. Results point out not only initial conditions of anguish, doubts and hardships, but also a will to debate difficulties Physical Education teachers face in their daily pedagogical activities at school. Likewise, results showed that teachers who took part in the research are interested in continuing their training in connection with co-teaching as strategy to teach physical education at inclusive schools.

Preparação e caracterização de biomateriais poliméricos para avaliação da viabilidade de uso como phantom biológico

The theoretical and experimental developments in the biomaterials area have been directly applied to different fields of Medicine (odontology, regenerative medicine and radiotherapy). These advances have focused both for diagnosing diseases such as for quantifying degrees of progression. From the perspective of these studies, biomaterials are being designed and manufactured for application in various areas of science, provided advances in diagnostic radiology, radiotherapy dosimetry and calibration of radiotherapy equipment. Develop a phantom from a biomaterial has become a great ally of medicine in the treat patients with oncological diseases, allowing better performance of the equipment in order to reduce damage to healthy tissue due to excessive exposure to radiation. This work used polymers: chitosan and gelatin, for making the polymeric structures and controlled for different types of production and processing, characterizing and evaluating the biopolymer by physical techniques (STL, SEM and DEI) and therefore analyze applicability as phantom mouse lung. It was possible to evaluate the morphology of biomaterials quantitatively by scanning electron microscopy associated with imaging technique. The relevance of this work focuses on developing a phantom from polymeric biomaterials that can act as phantom providing high image contrast when subjected to analysis. Thus, the choice of DEI technique is satisfactory since it is an imaging technique of X-ray high resolution. The images obtained by DEI have shown the details of the internal microstructure of the biomaterial produced which have ≈ 10 μm dimension. The phantoms had made density ranging from 0.08 a 0.13 g/cm3.
