The cosmetic industry has presenting growth in Brazil and one way to support this demand is improving production and reducing waste. Wastes can be related to setup time, which is spent to support demand of product´s mix and volume. One of the methodologies used to reduce setup time is SMED (Single Minute Exchange of Die). This paper aims to describe and analyze the setup process in a production line in a cosmetic industrial branch, before and after the application of SMED methodology, highlighting good practices and difficulties in order to help other companies develop fast setup. The research method used was the case study. From the analysis of the implementation of the methodology on the company which is object from the case study was possible to summarize good practices, such as: the use of pillar E&T to store information about the training on the SMED methodology; creation of a multifunctional teamwork and involving different areas; creation of a “From-To” matrix. Difficulties were identified, such as: high and constant turnover of people who work on the shop floor; lack of discipline in filling the forms and by doing the setup activities that were standardized; lack of financial resources; lack of people´s availability in orer to conduct necessary meetings and trainings. Recommendations for other companies have also been proposed, such as: training of the team involved, before starting the project and a refresher training; standardization of training, forms and documentation of all steps of the project; create a multifunctional team; training after an employee, who is responsible for the setup, leaves the company

Discussões a respeito de propostas de intervenção em espaços ur-banos que possuem valores culturais para a comunidade têm sido um tema bastante explorado por arquitetos e urbanistas contemporâneos. Muitos são os teóricos que se ocuparam do assunto – as primeiras teorias de restaura-ção do patrimônio arquitetônico construído datam do século 18 – mas, até hoje, não se pôde estabelecer um consenso sobre como se deve ou não proceder na concepção de projetos dessa natureza. Este trabalho trata de um espaço ocioso na área central do municí-pio de Bariri, interior do estado de São Paulo, onde se deram as atividades de uma indústria de óleos vegetais de grande expressão na cidade, entre as décadas de 1960 a 1980. Mesmo depois de a fábrica ter entrado em proces-so de falência, seus equipamentos e edificações permaneceram no terreno, e, até hoje, parte considerável de seu patrimônio construído ainda continua lá. Porém, nunca se deu outro uso para o espaço, sendo que, atualmente, as instalações se encontram em processo de ruína. Sabe-se que áreas desocu-padas inseridas na malha urbana podem levar a uma degradação do espaço, devido à falta do cuidado mantido pela presença humana, causando, diversas vezes, a perda do controle pelo poder público, e incidentes provocados pela falta de segurança. A Indústria Resegue de Óleos Vegetais (IROV) teve considerável importância histórica para o município, sendo um dos maiores símbolos da atividade econômica dos imigrantes sírios na cidade. Foi responsável pelo emprego de muitos trabalhadores e por grande movimentação financeira na época em que esteve em funcionamento. Além disso, seu espaço físico im-ponente está presente no cognitivo da maioria dos habitantes baririenses, compondo, de maneira significativa, a identidade visual de Bariri. Sendo as-sim, trata-se de uma área de interesse cultural... (Resumo completo, clicar acesso eletrônico abaixo)

Therebar of aluminum 1350 AA produced by CBA are used inthe manufacture of wires and cables for electric power transmission, which marketshows increasingly favorableto aluminum due to itslow densityand high electrical conductivity, but to ensure that this materialmeets all specifications of projectsfor electricity transmission, it must have homogeneity in the chemicaland mechanicalproperties.One of the points of improvement in the process of rod production isreducing the high variation of the limitof tensile strengthalong the coils, therefore, this work seeks a better understanding of the factors that significantly influence the mechanical properties of rebar, specifically assessing the influence oftemperatureat the output of the coils, which can cause a recovery effect on the material andif thereare relevantdifferences between the two modes of rebar production: auto and manual.Samples of six coils have been specifically produced forthis study, which weresubsequently subjected to different annealing temperatures for one hour and ten minutes, similar to what occurs in the output of the coil from the machine. The tensile tests showed that aluminum 1350 AA is significantly influenced by temperature, whose behavior was very similar to that presented in the literature. It was found that the phenomenon of recovery occurred more significantly at high temperatures. Through the optical electron microscope Zeiss, 18 surface maps were made with 100x magnification for each sample in different conditions and the images were analyzed using entropy and fractal dimension, aiming to relate the condition of surface hardening on mechanical property of the samples in that condition. The results showed that these methods can be applied, provided they do not have any kind of imperfection on the surface, once they can influence the results. The study concluded that a more efficient cooling is required in ... (Complete abstract click electronic access below)

This work is an action research conducted in an industry of consumer goods, presenting a new model of inventory management in the company's processors. This replacement of the inventory management of the company stemmed from the need to reduce the large number of deviations in the product write off in stock, thereby generating a low accuracy and reliability of data on inventories of processors shown by the company's ERP system. Spending on inventory adjustments could thus be reduced with the implementation of the new model, thus generating a cost savings for the company and thus increasing their competitive potential in the market. In the old system adopted by the company, write off raw material inventory was done automatically by the system for customized transactions by the company. However, since the implementation of ERP in the company, the automatic write off based on historical consumption of each product were made in many cases at random, generating a lot of mistakes. The new management system has replaced the automatic system by manual at the time of the return of the processed product in the company, thus creating a control which lots and quantities were consumed in the processing and making the stock shown by the ERP reliable and accurate
