O cinema como educação do olhar

The knowledge is only possible due to we exist bodily. However, during the educational experience, the epistemic potency of the body is neglected, declining the registers of the intelligibility. The current thesis approaches that problem obliquely: from a body and image philosophy which has revealed other ways of doing those registers in the modernity – understood not as period itself, but as a qualification for the negotiations between the real and the intelligible. The referred ways are explored through Merleau- Ponty’s and Michel Foucault’s works, which offer a spectrum about that new negotiation of the real. In order to approach the studied problem, the visibility and the human body motricity in the cinema are taken as analysis object. The mentioned objects have been analyzed through a corpus of movies of which plots are centered at the formal education and they require from the characters and the spectators engagement into a visual performance. Aiming to approach the object, it is questioned how the Education phenomenon is represented by the cinema; how the body is exposed and how spectators can see it. Analyzing the corpus and articulating Merleau- Ponty’s and Michel Foucault’s theories, it has been possible to state the following thesis: the cinema as an education of the gaze. The general objective of this study is to reveal the educational potency of the filmic experience, which provides a new path of intelligibility for Education. In that sense, the body as a visual operator widens the capacity of understanding the real. The current work is divided in three chapters. The first one brings the methodological approach: it is pointed how the theoretical articulation is properly arranged; it explains the method of using the images as indirect language as part of the reality description; the filmic corpus is presented, as well the criteria for the films choices and for the construction of instrument adopted during the object analysis are described. In the second chapter, it is problematized the incapacity of the western society of formulating the real discursively by debating Merleau-Ponty’s and Foucault’s theoretical contributions about the visual performance displayed on the images while the films are watched and analyzed. In the third chapter, the implications of the education of the gaze provided by the cinema are developed, mainly concerning about the place attributed to the visibility during the formulation of the real. Finally, paths are designed for the construction of another approach for the visibility in Education. Assuming the gaze as an experience of knowledge, this study aims to present other ways of being, seeing, thinking and feeling the world. Therefore, it is a proposal to reset the epistemic and subjectification patterns at the educational context.

Materiais bionanocompósitos a base de argilominerais e hidróxidos duplos lamelares como sistemas de liberação de fármacos

Bionanocomposites systems clay base (montmorillonite and sepiolite), layered double hidroxides and biopolymers (carboxymethylcellulose and zein) were evaluated as topical delivery systems with antibacterial activity and as oral delivery systems. For this study, neomycin, a topical antibiotic, indicated mainly for open wound infections. The drug amoxicillin, an antibiotic indicated mainly for throat infections, were also used in this study. Both antibiotics were used as model drugs. Initially, drugs were incorporated directly into the biopolymer matrix, comprising the combination of carboxymethylcellulos and zein, being conformed as movies and balls and evaluated for their antibacterial activity and controlled release simulating gastrointestinal fluids. Moreover, hybrids materials have been prepared where the neomycin drug was incorporated into the lamellar inorganic solids, such as montmorillonite by ion exchange reaction, and the fibrous type, such as sepiolite by adsorption in aqueous solution. But the drug amoxicillin was incorporated into layered double hydroxides by anion exchange and montmorillonite by cation exchange. The resulting hybrids were in turn combined with the biopolymer matrix yielding bionanocomposites shaped materials such as films were tested for their antibacterial activity, and the shaped materials beads were tested for their release in the gastrointestinal fluids. Through the analysis of various physico-chemical techniques, we observed the interactions between the studied materials, the formation of hybrids materials, obtaining the bionanocomposites materials and material efficiency when applied in controlled release of drugs both topical and use oral mainly influenced by the presence of zein, are promising as topical delivery systems and oral drugs.
