In this paper, a method is proposed to refine the LASER 3D roofs geometrically by using a high-resolution aerial image and Markov Random Field (MRF) models. In order to do so, a MRF description for grouping straight lines is developed, assuming that each projected side contour and ridge is topologically correct and that it is only necessary to improve its accuracy. Although the combination of laser data with data from image is most justified for refining roof contour, the structure of ridges can give greater robustness in the topological description of the roof structure. The MRF model is formulated based on relationships (length, proximity, and orientation) between the straight lines extracted from the image and projected polygon and also on retangularity and corner injunctions. The energy function associated with MRF is minimized by the genetic algorithm optimization method, resulting in the grouping of straight lines for each roof object. Finally, each grouping of straight lines is topologically reconstructed based on the topology of the corresponding LASER scanning polygon projected onto the image-space. The results obtained were satisfactory. This method was able to provide polygons roof refined buildings in which most of its contour sides and ridges were geometrically improved.

Considering that the current pedagogical project for the Dentistry course at FOA-Unesp was structured in 2001, a year before the national resolution that introduced the new curricular guidelines for the dental field, the aim of this study was to analyze critically this document and assess the academic perception of the pedagogical project, as well as the current curricular structure. A previously tested and validated semi-structured questionnaire was used to obtain the needed information, and a documentary analysis was conducted. The questionnaire was drafted based on data from the National Curricular Guidelines (DCN) and Unified Health System (SUS) guidelines. The sample consisted of almost all the graduating students of 2007 (n = 61). Of these, 95% had no knowledge of the pedagogical project for the undergraduate course; 53% found the integration between the disciplines offered by the course insufficient; 66% pointed out that there was duplication of the revised contents; 41% said that the interdisciplinary relation was unsatisfactory, and 67.2% said they preferred the modular system of teaching. Furthermore, 55.7% of the students said that that the course does not fully cover the principles of completeness and resolution of actions, and 37.7% pointed out that clinical care was not humanized. As for the competence and skills needed to exercise the profession, the students admitted feeling secure about carrying out preventivecurative clinical actions, and feeling insecure about developing broad ranging actions, like managing and planning. Analysis of the documents showed a certain disagreement in the organization of the pedagogical project and the curricular structure, when confronted with the course of action set down by the National Curricular Guidelines. The data prove the urgent need to restructure the FOA-Unesp curriculum and confirm the importance of a continuous evaluation in higher education.
