Um olhar sobre a lei Maria da Penha no Paraná: avanços e desafios

This study aims to analyze the process of implementation of Maria da Penha Law in Paraná from the perception of persons directly involved in combating violence against women in that state. To achieve this goal, the implementation in Curitiba was taken as the main reference, due to its status as capital, being the headquarter of the political powers and the place where are some feminist social movements. We have chosen qualitative approach of interpretative nature as research methodology, because it is a method that allows the analysis of the responses and as a data collection technique. We also have chosen the individual semi-structured interview as interview mode, because it gives greater freedom to the interviewee to discuss the matter, but it is delimited to the study objectives. The research included nine persons, including members of the Judiciary and Public Ministry, public servants and activists. The importance of the study stems from the relevance of the numbers of violence against women in Brazil, and more specifically by the significant occurrence of this kind of acts in the state of Paraná, which currently occupies the 3rd place in the ranking for the most violent states. The paper also discusses gender relations by understanding that violence against women is the result of an asymmetrical power relationship between men and women; human rights because violence is a blatant disregard of women's human rights; on public policies and technologies to confront this form of violence. Among the policies, the Maria da Penha Law is highlighted as one of the most striking examples of public policy for combating violence against women. The research found out which was the participation of Paraná in the discussion and implementation of Maria da Penha Law, identifying relevant facts and people and also what was the repercussion obtained by this law. As for the implementation in Paraná, it was possible to determine progresses, difficulties and challenges of the process. The greatest advances obtained so far are the facilities of: Court of Domestic and Family Violence against Women in Curitiba, Maria da Penha Patrol and Women's Special City Office of Curitiba. As for the difficulties, they are related, among others things, to the physical structure, training of agents, political will, and even cultural issues, which are directly linked to gender issues. Thus it was found that the law is implemented in the state, but there are still several challenges to be achieved, which consist, mainly, of the structure increment for combating violence; awareness and change of mentality of public officials; training of service agents and a greater social participation in combating violence. We concluded that the need for change in gender relations, which is an educational and social evolutionary process and therefore time consuming, is also a challenge.

Uma nova abordagem do método Level Set baseada em conhecimento a e priori da forma

The analysis of fluid behavior in multiphase flow is very relevant to guarantee system safety. The use of equipment to describe such behavior is subjected to factors such as the high level of investments and of specialized labor. The application of image processing techniques to flow analysis can be a good alternative, however, very little research has been developed. In this subject, this study aims at developing a new approach to image segmentation based on Level Set method that connects the active contours and prior knowledge. In order to do that, a model shape of the targeted object is trained and defined through a model of point distribution and later this model is inserted as one of the extension velocity functions for the curve evolution at zero level of level set method. The proposed approach creates a framework that consists in three terms of energy and an extension velocity function λLg(θ)+vAg(θ)+muP(0)+θf. The first three terms of the equation are the same ones introduced in (LI CHENYANG XU; FOX, 2005) and the last part of the equation θf is based on the representation of object shape proposed in this work. Two method variations are used: one restricted (Restrict Level Set - RLS) and the other with no restriction (Free Level Set - FLS). The first one is used in image segmentation that contains targets with little variation in shape and pose. The second will be used to correctly identify the shape of the bubbles in the liquid gas two phase flows. The efficiency and robustness of the approach RLS and FLS are presented in the images of the liquid gas two phase flows and in the image dataset HTZ (FERRARI et al., 2009). The results confirm the good performance of the proposed algorithm (RLS and FLS) and indicate that the approach may be used as an efficient method to validate and/or calibrate the various existing equipment used as meters for two phase flow properties, as well as in other image segmentation problems.
