Using a blank compound as reference and brass coated steel tire cords with 64 and 68.2 % of cooper content, it was studied the effect of the ingredients cobalt and the HMMM-resorcinol system, and the vulcanization temperature on the rubber-brass adhesion. Samples were studied as new (original), aged in oven, steam and humidity environments. Mechanical properties, vulcanization kinetics and cross linking density were analyzed in the compounds. The ingredients, as well as the vulcanization temperature, showed a strong effect on the compounds properties, however, it did not show relation with the adhesion. The steel tire cords were evaluated by scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDS), being evident variations on brass deposition, which can lead to adhesion loss. The adhesion of the samples was evaluated by means of the force and coverage by pull out tests from a rubber block. The results, for each condition, were statistically analyzed. For the original condition, the steel cord with high content of cooper (68.2 %) showed higher adhesion values. In oven, only the effect of HMMM-resorcinol system was statistically significant. Aging in steam, the most aggressive condition, showed that the use of cobalt was effective in the maintenance of the adhesion level. Aging with humidity showed that the adhesion promoters cobalt and HMMM-resorcinol system were beneficial to the rubber-brass adhesion. The cords surface, after the extraction of the rubber, was evaluated by SEM and EDS. The formation of a CuxS structure, responsible for rubber-brass adhesion was evident. In general, it was not found a unique combination which guaranteed the maximum adhesion level for the studied conditions, however, the better balance was achieved using a steel cord with 64 % of cooper, the adhesion promoters cobalt and HMMM-resorcinol system, and the vulcanization temperature of 150 ºC.

In the last decade there has been a growth on society concern with topics related to epics, citizenship, human rights, economic development and social belonging. In this sense, all kinds of organizations are more and more worried on reaching and showing performance related to environment protection, socially and economically correct, controlling the impacts of its relations, processes, products and services in society according to its politics and its social responsibility goals. However, many doubts concerning what really is socially responsible in practical application, therefore in its speech. Although there has been indicators that point to the industries mentality and posture change related to its engagement in the social space. The reasons which promoted it are still doubtful. Probably this reasons must achieve specific shaping in specific realities as well, so the importance of the study: a contributions on the comprehension as how the industrial social responsibility is configured in the Sao Paulo´s orange-juice complex. Thus, the objective of this work is to design a framework of industrial social responsibility in the citric section of the São Paulo State and therefore there has been developed a case study of three different important agents in this reproductive chain. Throughout this study there is a search to build up an analysis in the comprehension of this issues on what concerns to be socially responsible, approaching and existent dynamic in the sector environmental institution that reinforces the adoption and the restructuring of acts related to industrial social responsibility. As a result it has been notice that the socially responsible acts are acts which has been an adaptation from pressure received by each agent, as well as they are isomorphic within each segment since it can be verified the existence of realities, power and legitimacy very different among the agents. It has also been noticed that the activities has been well accepted by human resources professionals and that the industrial social responsibility has been taken as a management tool.
Formação em serviço sobre gestão de escolas inclusivas para diretores de escolas de educação infantil
(Universidade Federal de São Carlos, 2006-12-18) Carneiro, Relma Urel Carbone; Mendes, Enicéia Gonçalves; https://lattes.cnpq.br/3897627554738983; https://lattes.cnpq.br/4107755396897795
We live in the context of a global society, in which changes are demanded in all aspects in the search for a better quality of life for mankind. In addition, there is an increase in the proportion of excluded individuals and thus there has been much discussion on social inclusion in political and educational debates. The school, as a segment of society, has also been facing the task to offer a better quality of education to all children. In the specific case of children with special needs, there has also been discussion within the concept of inclusive schools, which should be open to the differences. Considering the current demands, improvements in the qualifications of school teams is fundamental to assure the necessary transformation of schools, and the national research on school inclusion has been contributing to the problem of formation and work of teachers. However, it should be remembered that the leader role played by the school director has been identified as a primary factor for the achievement of increasingly inclusive schools. Thus, considering that this role played by the director requires new knowledge, attitudes and abilities to deal with the current conditions and emerging tendencies in general and special education, the present study aimed to develop, establish and evaluate a training program for directors of child schools, from the standpoint of school inclusion. Initially, a study was conducted on the professional profile of the school directors and their needs, by observation of the work routine of a director for four months, comprising 21 visits for observation and analysis of school records (school planning and statute). Thereafter, several people were interviewed (the director, the teacher of a student with special needs, the parents of this student, and the pedagogue assisting this child at a specialized center) with a view to achieve more knowledge on the role played by the director from the standpoint of each of these individuals. Based on the collected data and concepts developed by authors in the field of school management and inclusion, a closed questionnaire was prepared and sent to all 60 directors of municipal child schools from the city of Bauru, to collect further information on the training needs of these professionals to allow them to work as managers of inclusive schools. The results of this first study indicated that, even though they have legal knowledge on the policies of school inclusion, in practice the role played by the director seemed to be characterized by emphasis on bureaucratic issues of the school, centralization of decisions and lack of knowledge on how to respond to the educational demands of individuals with special needs. Following, a training program was developed and established for 41 directors of child schools. The program comprised theoretical issues on the problem of inclusion and practical activities of management and solution of problems related to the actual difficulties of daily work. The program was evaluated by: a) tests for group resolution of the same problem situations, at onset and completion of the program, b) personal reports on people with special needs collected before the program, c) reports based on a questionnaire with five open questions on the changes observed after the course perceived by the directors themselves, and d) a closed questionnaire on the formal aspects of the program. The results indicated that the program yielded the expected results in the perceptions and attitudes of directors, at least from their reports. Discussion was based on the conclusion that, even though such initiatives of training programs are necessary, they are not sufficient, since the transfer of changes from reports to the educational practices in the daily life of schools is not automatic, which suggests that training should go further and assure follow-up by collective work and establishment of a culture of collaboration and appreciation of human diversity. Finally, the way to change seems to be focused on the challenging role of the director, who must have a firm leadership yet simultaneously must promote collective processes of planning, organization and development of the political-pedagogical project of the school
Utilização de geradores de aplicação em processos ágeis de reengenharia
(Universidade Federal de São Carlos, 2006-12-18) Freitas, Raquel Gonçalves de; Penteado, Rosângela Aparecida Dellosso; https://lattes.cnpq.br/4061946080136286; https://lattes.cnpq.br/5735959284310531
Agile methods, through their principles and values, propose to make software development more flexible, thus satisfying the customer in a rapid and customized way. Quality has a fundamental role both in software development and in software maintenance. It is known that, for a product to have quality, guidelines have to be followed along the whole development process as well as software maintenance. Software reengineering is a solution for those systems in which maintenance grew difficult with time. Some reengineering processes use software patterns which provide success solutions for recurrent problems and, also seek agility, avoiding the waterfall process model. Application generators provide agility in software development, as they help the process automation for a certain domain. This dissertation aims to use application generators, more specifically GawCRe (Gerador de aplicações para web de Clínicas de Reabilitação web application generator for rehabilitation clinics) together with ARA (Arcabouço de Reengenharia Ágil Agile Reengineering Approach), instead of the GREN (Gestão de REcursos de Negócio Business Resource Management) framework. Through a prospective case study, conducted with four legacy systems belonging to the medical clinics domain, it has been observed that ARA supports that applications generators use, although it is necessary to make an adaptation in order to allow it. This is true even though the legacy systems domain is not the same as that of the application generator. The generator adaptation has been easier because it is specified in XML. As the code that it generates is in Java, it has been possible to use the Eclipse environment though to produce the classes diagrams necessary to future maintenance. This enforced the reengineering process adaptation so that the classes diagrams production commended to be prepared before code generation passed to be produced after that generation.
