A Construção/reconstrução das competências profissionais do assistente social diante da gestão do serviço social da indústria SESI a partir dos anos 90

L´étude du processus de construction / reconstruction des compétences de l´assistant social sous la gestion du SESI (Service Social de l´ Industrie), Natal/RN, dès la moitié des années 90 a réaffirmer la perspective que ce processus est le résultat de déterminations macrosociétaires qui sont présents, particulièrement au Brésil, aussi que, la façon par laquelle l´assistant social, le professionnel inscrit dans la division sociale et technique du travail, fait développer son perfectionement technique et intelectuel dans un milieu de nouvelles structures productives qui éxigent un nouveau profil du professionnel face à la crise du capital et de l´État. Cette recherche, de nature qualitative et quantitative, a eu lieu par de combinaisons de recherche bibliographique et empirique. Les sujets ont été huit assistants sociaux et six travailleurs administratifs du SESI, Natal/RN. Les donnés ont été obtenus par des interviews semi-structrées. On a analisé les changements qui sont arrivés dans les gestions du SESI et les compétences qui sont éxigées de l´assistant social ; l´influence du milieu socio-occupationel sur l´action professionnelle et sur le processus de construction/reconstruction de compétences; l´agrandissement de demandes institutionnelles pour l´assistant social par rapport à la prestation de services ; aussi que la constatation de l´importance de ce professionnel, sa hardiesse, mais aussi quelques limites et défis affrontés face à la qualification stimulé par le SESI, en amenant le professionnel dans un processus contradictoire de qualification et disqualification professionelle

Determinação de Chaveamento para Recomposição do Serviço em Redes de Distribuição de Energia Elétrica em Média Tensão Através de Métodos Baseado em Parâmetros de Sensibilidade

The reconfiguration of a distribution network is a change in its topology, aiming to provide specific operation conditions of the network, by changing the status of its switches. It can be performed regardless of any system anomaly. The service restoration is a particular case of reconfiguration and should be performed whenever there is a network failure or whenever one or more sections of a feeder have been taken out of service for maintenance. In such cases, loads that are supplied through lines sections that are downstream of portions removed for maintenance may be supplied by the closing of switches to the others feeders. By classical methods of reconfiguration, several switches may be required beyond those used to perform the restoration service. This includes switching feeders in the same substation or for substations that do not have any direct connection to the faulted feeder. These operations can cause discomfort, losses and dissatisfaction among consumers, as well as a negative reputation for the energy company. The purpose of this thesis is to develop a heuristic for reconfiguration of a distribution network, upon the occurrence of a failure in this network, making the switching only for feeders directly involved in this specific failed segment, considering that the switching applied is related exclusively to the isolation of failed sections and bars, as well as to supply electricity to the islands generated by the condition, with significant reduction in the number of applications of load flows, due to the use of sensitivity parameters for determining voltages and currents estimated on bars and lines of the feeders directly involved with that failed segment. A comparison between this process and classical methods is performed for different test networks from the literature about networks reconfiguration

No fio da meada: um estudo acerca da precarização do trabalho na indústria têxtil

In line with the process of financialization and globalization of capital, which has intensified in all latitudes of the globe, the world of work is permeated by his determinations arising and also has been (re) setting from numerous changes expressed by example, in the unbridled expansion of temporary forms of work activities, and flexible outsourced by the growth of informality, forming a new morphology of work. However, regardless of how these forms are expressed in concrete materiality, there is something that unifies: all of them are marked by exponentiation of insecurity and hence the numerous negative effects on the lives of individuals who need to sell their labor power to survive. Given this premise, the present work is devoted to study, within the framework of the Brazilian particularities of transition between Fordism and Toyotism, what we call composite settings of the conditions and labor relations processed within the North river- textile industry Grande. To this end, guided by historical and dialectical materialism, we made use of social research in its qualitative aspect, using semi-structured interviews, in addition to literature review, information retrieval and use of field notes. From our raids, we note that between the time span stretching from the 1990s to the current year, the Natal textile industry has been undergoing a process of successive and intense changes in their modus operandi, geared specifically to the organization and labor management causing, concomitantly, several repercussions for the entire working class.
