This article discusses the awareness process of students in a Spanish as a foreign language classroom, at a Centre of Language Studies in a city in the state of São Paulo, Brazil. The frame of reference is Paulo Freire's pedagogy (FREIRE, 1980, 1984, 1987, 1999, 2000), Wallerstein (1983) and Schleppegrell (1997)'s investigations which are important to the comprehension of the relation between Freirean's pedagogy and the language teaching. This is a qualitative research and it focuses on action research practice in a Spanish language classroom, in which a syllabus based on Paulo Freire's pedagogy was implemented in order to verify how the target language was used in the classroom (MENEGHINI, 2001). Data analysis and discussion are based on data triangulation and classroom interactions are taken on primary data. The implementation of this research suggests that the problem posing tasks on themes chosen from the student's realities are the way which leads to the awareness.

The aimof this study was to evaluate the stress distribution on bone tissue with a single prosthesis supported by implants of large and conventional diameter and presenting different veneering materials using the 3-D finite elementmethod. Sixteenmodels were fabricated to reproduce a bone block with implants, using two diameters (3.75 × 10 mmand 5.00 × 10 mm), four different veneering materials (composite resin, acrylic resin, porcelain, and NiCr crown), and two loads (axial (200 N) and oblique (100 N)). For data analysis, the maximum principal stress and vonMises criterion were used. For the axial load, the cortical bone in allmodels did not exhibit significant differences, and the trabecular bone presented higher tensile stresswith reduced implant diameter. For the oblique load, the cortical bone presented a significant increase in tensile stress on the same side as the loading for smaller implant diameters. The trabecular bone showed a similar but more discreet trend. There was no difference in bone tissue with different veneering materials. The veneering material did not influence the stress distribution in the supporting tissues of single implant-supported prostheses. The large-diameter implants improved the transference of occlusal loads to bone tissue and decreased stress mainly under oblique loads.Oblique loading was more detrimental to distribution stresses than axial loading. © 2013 Elsevier B.V.
