Trabalho, educação e desenvolvimento: o norte da educação da CUT na Amazônia

This thesis is the result of a bibliographic and field research, with the purpose to answer in what way the process of education developed by the CUT, expressed in the experience of the Project Vento Norte, developed in the Amazônia has colaborated in the sense of the possibility of a articulation between work, education, and develpoment. The bibliographic reasearch was based in the studies of theoreticals like Gadotti (1999), Marx (1998, 1998a), Pochman (2002), Brandão (1985, 2002), Adorno (1999, 2000), Horkeimer (1976), reseachers that in the process of their studies, thinked about the theme, related to work, to education and to developement. The field research was done by the intervews with CUT s educators and managers from the states of Acre, Amazonas, Amapá, Pará, Rondônia and Roraima. The thesis s process of elaboration is done in a cobweb of elements articulated to socioculture values from the habitat of amazônia people. The conclusions point to us that the hypothesis of the CUT, by the Project Vento Norte, develops a propose of education that articulates Work, Education and Development that is confirmed. But, the partiality of the project is presented by the limitations of the CUT s possibility in continuation of the project. Thats why the thesis suports the idea of the project and it consolidation in the Amazônica Region, by the conception of the syndicate managers and educators

Compósito reforçado com sisal para aplicação na moda

The objective of this research is the fabrication of a composite reinforced with dyed sisal fiber and polyester matrix for application in the fields such as, fashion, clothing, interior textiles; fashion accessories are some of the examples. For the fabrication of the composite, the sisal fibers were subjected to processes such as: chemical treatment with sodium hydroxide (NaOH) in the removal of impurities; bleaching for removing the yellowish color of the natural fiber and dyeing with direct dyes to confer the colors blue, green and orange. The search for new technologies ecologically correct has become a major concern in recent decades. Studies show that composite polymer reinforced by natural fibers is suitable for a large number of applications, and its use is advantageous in terms of economic and ecological. The dyed fibers were cut to a length of 30 mm, is used in the confection of webs. For this purpose, a web preparer by immersion, developed in the Laboratory of Chemical Textile of UFRN. The composite sheets measuring 300 x 300 x3 mm were molded by compression, with unsaturated orthophthalic polyester as matrix, and the samples in sizes 150 x 25 x 3 mm were cut with the aid of a laser machine, to be subjected to traction and flexion. The mechanical properties of traction and flexion in three points were performed in the Laboratory of metal and mechanical tests of Materials Engineering of UFRN. The resulting samples from the tests were evaluated in scanning electron microscope (SEM) at CTGas RN. On the basis of the analysis of the results from the mechanical tests, it was observed that the composite had good mechanical behavior, both in traction as in flexion. Furthermore, it was observed that in the water absorption test, the samples had a different percentage among themselves, this occurred due to the variation of density found in the fibre webs. The images of the SEM showed the failures from the manufacturing process and the adhesion of fibre/matrix. When the samples were prepared with the dyed fibers to be applied in fashion, the results were positive, and it can be concluded that the main objective of this work was achieved

A Central Única dos Trabalhadores (CUT) no embate das contrarreformas da previdência social: contraposição ou consenso?

The provident rights were results of intense fights in between the capital and work, claiming the interventions of the state for the creation of an ample social protection system. In Brazil the law, Providence Social mark, dated 1923, from then on, the advances and extensions were many, of this diverse categories of politics. Mean while, in the 1990 s, the Brazilian government adopted the examples of other developed countries, the new pattern that hinted the realization of substantial changes on the states purpose, the reached rights and the proper organization of working classes. For the Social Providence, the principal loses turned out in 1998 and 2003; respectively in FHC governments and Lula, with the realization of two counter reforms that restricted the provident rights and motivated the privatization of public providence. In the scenery, the CUT, one of the representative organizations from working classes, founded in 1983, that has always itself with changed direction, from fighting to negotiating. This inflection determined the proposition of the center before the offers of the counter reforms, of Social Providence. The present work has the objective to analyze the social politic content of the fights from Brazilian union movement in the period of the conquests and disassembled rights and, to analyze the proposition, acting and offers from CUT in the counter reform period from Providence in the Government FHC and Lula. To perform this study beyond the essential bibliographical revision to found and deepen the subject, we use, the documental search through the internet pages, resolutions, informations and others publications from CUT. Using CUT in the governments worked in an elegant way, the FHC government against-reforms, showed itself through diverse actions, even though they didn t have homogeneous inside, contrary the neoliberalists politicians from this government, also the offers and precaution changers. While during the reign of Lula it shoved itself priority negociative and propositive
