Utilização de 5S, Kanban e Layout para a melhoria do controle de estoque em um varejo de materiais para construção

Many small businesses suffer from a lack of control of goods stored. This lack of control affects other areas of the company as purchase, that can’t buy material in an advanced and accurated way. It also affects services provided by the company, especially when it is a store because for sell something it is necessary to have the material in the right time. Futhermore, the business isn’t able to identify obsolete items in stock, theft and vandalism, loss or damage to materials. All of these disorders can be converted into financial losses that make much difference to a small business that needs to remain competitive in the market facing the giants while generating a profit that allows it to invest in their growth. Therefore, any unnecessary expense is exceedingly harmful and any savings already differentiates it from other companies of similar size. This study deals with the application of production engineering tools as 5S, kanban and layout in a building materials retail to tackle problems that prevent this company to have a stock organized and accurated. Finally, we recorded gains that the company reached with the implementation of part of the solution proposed

Uma análise fenomenológica do uso de jogos e materiais manipulativos no ensino de matemática

This work investigates the reasons that take teachers to use or not use manipulative materials in mathematics education as well as the knowledge that teachers of Basic Education schools of the city of Guaratingueta have about such resources. The experience in the classroom, while participating in projects, showed that these resources are important allies in knowledge production. However, we noticed that they are not often present in the teachers teaching practice. This leads us to investigate the relevance of such education resources from authors like Grando (2000) and Macedo (2012) and try to see the idea that math teachers have about their use. For this research we developed a questionnaire and we headed teachers to obtain data. Assuming a posture qualitative with phenomenological approach, organized researched data and interpreted following the procedures described by Bicudo (2011) and Machado (1994). We built three categories or regions of generality that lead us to consider that, for our research subjects, the use of manipulative materials is significant as Didactic Resources and Learning Aid, however, used from a Naïve Knowledge that does not involve reflection on practice or relies on theoretical concepts

Recursos humanos e materiais na assistência de enfermagem a pacientes de uma unidade de tratamento de queimaduras

The burn is among the leading causes of morbidity and mortality in our society. It shows a great complexity and is hard to treat. Beyond the physical suffering, the burned patient is affected by psychological distress, requiring a high level of knowledge for assistance planning. The Professional Practice Law No. 7498 establishes the nurse as in charge of the client, as leader of the nursing team and as responsable for the management of physical and human resources. The nurse has autonomy to design the quantitative and qualitative picture of the nursing staff and should use the methodologies for their suitability to the real levels of assistance needed. Material resources represent 15 to 25% of total expenditures at health organizations. Therefore, to maintain the care level, nurses must determine the needs, considering the quantitative, qualitative and financial aspects. The study aimed the survey of the human and material resources necessary for nursing care to patients in a Burns Treatment Unit and identify its epidemiological profile and its nursing diagnoses. We collected the data from medical records of hospitalized between July and August, and the nursing diagnoses were classified through the Taxonomy II proposed by the North American Nursing Diagnosis Association (NANDA). The design of the picture of nurses followed the parameters of COFEN Resolution nº 293/2004. We apply the Fugulin's Patients Classification System to establish levels of the required care. The institution's Cost Center provided a spreadsheet with the purchased items, subsequently classified into ABC. Most hospitalized patients were men, aged between 20 and 50. There was a predominance of patiences with minor burned and the most common type of burn was due to fire. The average residence time was 28.71 days, and 88% of the patients were discharged...

Biodegradação de materiais poliméricos por fungos filamentosos

The use of polymeric materials has grown in recent years due to its high durability features, atoxicity, shaping versatility and environment resistance. However, while these features represent good advantages to several industry sectors, it results in one of the most serious environmental problems of contemporary society: the rising accumulation of these material, mainly due to the inadequate disposal of waste. Meanwhile, in order to minimize this problem, some mitigation techniques comes up (arises), among which the use of biodegradable polymers has been gaining attention. Because of their easily action of microorganisms, such material degrade more rapidly, becoming integrated to nature. Furthermore, due to the fact of biodegradation is a natural process, occurring through the action if micro-organisms in the environment itself, it is considered the “cleaner” alternative found so far to plastic components reincorporation in the nature. Among the micro-organisms capable of biodegradation process are the filamentous fungi. These micro-organisms have many advantages over the others, the major one being the capacity to produce a range of enzymes capable of degrading different materials. In this context, the present review made it possible to see the importance of this process as an agent of environmental preservation, suggest the use of blends to minimize the problems of cost and flexibility of biodegradable polymeric materials, as well as noting the lack of studies related to this subject nowadays

Avaliação mecânica da colagem estrutural entre compósitos poliméricos e materiais metálicos utilizados em dutos petroquímicos

The development of technology for structural composites has as one of its ends form a set of materials that combine high values of mechanical strength and stiffness and low density. Today, companies like Embraer and PETROBRAS and research institutions like NASA, working with these materials with recognized advantages in terms of weight gain, increased performance and low corrosion. We have developed a systematic study to determine the bond strength between composite carbon fiber / epoxy and fiberglass / epoxy laminate both bonded to a carbon steel which are widely used in the petrochemical industry and repair.
