Adaptação da produção aos objetivos de competitividade e produtividade: a pesquisa-ação em uma manufatureira de cutelaria inserida em rede

One of the oldest segments in operations management, whose models are always subject to development efforts, for academics and productive organizations, is the management of production and work organization. Proposals for strategic management principles that seek to bring production to streamline processes reduce costs and add value, identifying problems with material flow and information while reducing the response time. This is realized through the pursuit of the best actions to achieve goals and targets established in a successful Planning and Production Control. This article aims to identify and implement actions that increase the speed of supply of goods produced in a enterprise cutlery; positively influencing the perception of customers. Such attitudes benefit all actors involved in the network, a fact which is expressed in the production chain. To lay the foundations of research and validate the data obtained, it was a study drawing on action research methodology. The goods produced are sold, mainly to wholesalers. Was proved seven aspects to improve and enhance the competitiveness of the organization, among them the complete design of the network, integrating upstream and downstream actors.

A cartografia geomorfológica como subsídio para a análise do relevo antropogênico em área de mineração

Mining activities are directly related to changes in natural landscapes. With the objective of analyzing the changes imposed by the geomorphological dynamics of human action in areas of mining clay, two fragments were selected from the basin of Ribeirão Santa Gertrudes / SP, representing denudational and sedimentation processes respectively. This area is within the context of the Ceramic Pole Santa Gertrudes / SP, which besides its importance as a supplier of raw material, is characterized as the largest center of international reference in ceramic tiles on the American continent. Data was collected and analyzed from the perspective of anthropogenic geomorphology supported by general systems theory and uses techniques from evolutionary geomorphological mapping. Thus, geomorphological mapping were produced concerning three scenarios, which date from 1962, 1988 and 2006 in a scale of 1:10.000. These surveys allowed us to infer a detailed investigation of the evolution of changes in topography and hydrology, geomorphology representative of the original (1962), which has characteristics of an earlier phase of earlier existing large mining pits, and its evolution to a anthropogenic geomorphological stage, represented by active disruption scenarios dating from 1988 and 2006. The last two scenarios have analyzed changes in the dimensions of relief features when compared with the original scenario representative of geomorphology, as well as an intense reallocation of surface and subsurface materials, in which human action is highlighted by becoming responsible for sculpting the landscape through the imposition of control mechanisms to natural processes.

Uma revisão sobre a resina uréia-formadeído (RUF) empregada na produção de painéis de madeira reconstituída

According to ABIPA (2009), Brazil is currently among the major producers of reconstituted wood panels, with one of the main factors for this condition, its climate and its large land area, which allows the cultivation of forests, which provide raw materials for these industries. To establish that market as power, Brazil has invested about R$ 1.3 billion in the last 10 years, yet designed an investment of 0.8 billion dollars over the next three years (BNDES, 2008). With the new investments in this segment, we expect a growth of about 66% in the resin consumption of urea-formaldehyde (GPC, 2009) which should also result in major investments by the companies producing this polymer. Currently employees are mainly three types of resins in the production industry panels, as follows: Urea-Formaldehyde Resin (R-UF), melamine-formaldehyde resin (R-MF) and Phenol-Formaldehyde Resin (R-FF). Especially the cost factor, the urea-formaldehyde resin is the most used by companies producing reconstituted wood panels. The UF-R is a polymer obtained by condensation of urea and formaldehyde reactors (usually batch type), characterized by being a thermosetting polymer which makes it very efficient for bonding wood composites. The urea-formaldehyde polymer, to present a quite complex, it becomes very difficult to predict the exact chain resulting in the process of condensation of urea with formaldehyde, so that a greater knowledge of its characteristics and methods for their characterization can result in greater control in industrial processes and subsequent decrease cost and improve the quality of reconstituted wood panels produced in Brazil

Simulação de produção de sedimentos em microbacias em função de cenários de restauração florestal

In São Paulo state, deforestation and agriculture activities are increasing soil losses processes, especially in areas of susceptible soils where properties not adopt soil conservation practices. Environmental adequacy at property level regarding Permanent Protection Areas and Legal Reserves is considered a factor on reducing soil losses and considering that we assessed soil losses of different scenario of environmental adequacy. Simulations of erosive process were carried out in 15 catchments of Corumbataí river basin, according to different forest restoration scenarios, as well as the current situation of land use/land cover. The scenarios include the implementation of Permanent Preservation Areas (PPA), the reforestation of variable source areas, and two scenarios, the Legal Reserve installation in 20% of each catchment, being one of them for most critical areas in terms of erosion and the other at random. It was observed that the establishment of PPA and the reforestation of hydrologically sensitive areas, offered only a small contribution to the control of the erosive process, resulting in a reduction of 10% and 7,8%, respectively, while the legal reserve in critical areas has a significant reduction of 69,8%. The random scenario, in turn, resulted in a reduction of only 21,4%. Results show that reforestation could reduce soil losses, but previous studies of land prioritization and planning could increase significantly its efficiency at this process.
