Conduções cênicas: A “Açon” e o movimento através dos princípios e procedimentos metodológicos de Gilles Gwizdek

The research identifies and describes the principles and methodological procedures of the director Gilles Gaetan Gwizdek on the transposition of the dramatic text to the space of representation through action and movement. Besides that, it presents the results of the experiment in two different labor camps and conducting modes: the no-actor student, inserted into the basic education, and the actor-student, inserted in higher education. Through the scenic paths encountered by the director, the individuals were could find their own ways and verify, through the scenic conductions, how such methodological procedures can achieve a pedagogical thinking about the actor's work. As theoretical referential, were studied the artists-educators: Jacques Copeau, in what sensitizes to the use of dramatic text, and Jacques Lecoq, it approaches of the physical use of the actor's body to the theater. The concepts about theater of the scholars in theater: Constantin Stanislavski, Eugênio Barba, Meyerhold, Eugênio Kusnet, Bertold Brecht go through the theoretical revisions of the thinkers: Odete Aslan, Patrice Pavis, Ney Piacentini, Lúcia Romano, Flávio Desgranges e Anne Bogart, in what affects their practical experiences and conceptual about the text, the action and the movement. It was analyzed also the practical experience based on the principles and methodological procedures of Gilles director, in rehearsals and performances of students in the ninth grade of the primary school the Basic School of the Federal University of Uberlândia - ESEBA, as also, of the students of the sixth, seventh and eighth period, of the Theater Graduation in the same university. From this analysis, it was proposed an interrelation between the theoretical and practical works, done by reading of the artists-educators about movement and Gilles Gwizdek in his work process. The research suggests that, from the movement, the student can build autonomously a character through the experience of small movements of the body. Thus, this student would increase his relationship between stage and audience, and consequently, he would cause a possible state of "seduction" of the spectator to the spectacle.

Classificação de nódulos pulmonares em imagens tomográficas utilizando redes neurais artificiais em cascata

Lung cancer is the most common of malignant tumors, with 1.59 million new cases worldwide in 2012. Early detection is the main factor to determine the survival of patients affected by this disease. Furthermore, the correct classification is important to define the most appropriate therapeutic approach as well as suggest the prognosis and the clinical disease evolution. Among the exams used to detect lung cancer, computed tomography have been the most indicated. However, CT images are naturally complex and even experts medical are subject to fault detection or classification. In order to assist the detection of malignant tumors, computer-aided diagnosis systems have been developed to aid reduce the amount of false positives biopsies. In this work it was developed an automatic classification system of pulmonary nodules on CT images by using Artificial Neural Networks. Morphological, texture and intensity attributes were extracted from lung nodules cut tomographic images using elliptical regions of interest that they were subsequently segmented by Otsu method. These features were selected through statistical tests that compare populations (T test of Student and U test of Mann-Whitney); from which it originated a ranking. The features after selected, were inserted in Artificial Neural Networks (backpropagation) to compose two types of classification; one to classify nodules in malignant and benign (network 1); and another to classify two types of malignancies (network 2); featuring a cascade classifier. The best networks were associated and its performance was measured by the area under the ROC curve, where the network 1 and network 2 achieved performance equal to 0.901 and 0.892 respectively.
