In this dissertation the subject of labor safety and health is approached, focusing on prevention of accidents when working in suspended scaffold, based on NR-18 as a preventive tool. The study initially presents information about Civil Engineering distributed in significant subjects for the intended targets is presented. In the second part details of suspended scaffold, pertinent guidelines of the NR-18 and no compulsory standards ABNT to be followed with this equipment are described. In the last part, the fulfillment of rules inserted in the NR-18, focused mainly to the suspended scaffold design, it is studied in the case study in a construction site. The conclusion shows the importance of the global view of the normative guidelines related to suspended scaffold, listed in this research, contributing for the complete fulfillment of the legal guidelines ans its improvement. The result achieved also might be useful as subsidies for the elaboration of the Conditions and Labor Environment Program for the Construction Industry, the project for the production of external covering, for the responsible organizations for monitoring of labor safety and health regulating standards
Abordagens para o problema integrado de dimensionamento e sequenciamento de lotes da produção de bebidas

The object of this study is the integrated problem of lot sizing and scheduling of the soft drink production. Such problem consists of deciding how much to produce of each drink and in each period and in which sequence, in order to satisfy the demand and to minimize the costs of storage, backlogging and changeover. The set up times of the machines are sequencedependent, consequently the production scheduling is complex. The problem is capacitated, multi-item, with changeover times and costs dependent of the sequence. In this study we propose three mixed integer optimization models and solution approaches to solve the problem. The models are based in cases studies of a large soft drink facility, and a small facility. We developed relax and fix heuristics to solve de models. The results show that the proposed strategies are competitive when we compare with solutions of the facilities.
