A globalização e a demanda de ações sustentáveis do mercado atual, exigem cada vez mais das empresas a busca da melhoria contínua. Os gestores das empresas buscam a todo o momento alcançar o máximo de resultados positivos para obtenção de lucro, com baixos custos de produção e que suas atividades sejam cada vez mais sustentáveis. A utilização de sistemas de indicadores de desempenho é uma alternativa para mensurar o desempenho organizacional, sendo reflexo desta preocupação. Este desempenho deve ser avaliado não apenas em informações financeiras, pois desta forma seria insuficiente para a compreensão do ambiente de negócios dinãmico da atualidade. A utilização de sistemas de indicadores constitui-se uma das principais iniciativas que podem ser implementadas para acompanhar a necessária modernização e evolução da indústria da construção, na busca de aumento de eficiência, eficácia e gerando efetividade nos diversos processos que constituem o sistema de produção. A estratégia de pesquisa utilizada é um estudo de caso, pois tem como objetivo compreender os sistemas de indicadores de desempenho utilizados na região metropolitana de Belém e a relevãncia destes para a tomada de decisão empresarial. Para a pesquisa foram realizadas 5 etapas: 1) elaboração de templates para coleta de dados, 2) seleção de empresas para realização da pesquisa, 3) levantamento de indicadores utilizados, 4) reuniões com as empresas participantes e 5) proposta de sistema de indicadores padronizados. Os principais resultados obtidos foram: (a) entendimento da dinãmica de utilização dos indicadores de desempenho na região; (b) compreensão do comportamento empresarial das empresas da construção civil da região metropolitana relacionados ao uso de sistemas de indicadores de desempenho; (c) proposta de um padrão de sistema de indicadores de desempenho como uma ferramenta de gestão para auxiliar na tomada de decisão empresarial. Verifica-se com os resultados obtidos a necessidade de desenvolvimento de estudos acadêmicos que estimulem a criação de ambientes propícios para a realização de práticas gerenciais colaborativas, na linha de gerenciamento da construção civil, em especial no desenvolvimento de clubes de boas práticas utilizando indicadores de desempenho.

The present work resulted from a study about coolant filtration systems in industries with metalworking process in large scale. The filtration and element filter world markets move billions of Reais per year and have a promissory future considering that with the global requirements of sustainable economic development, many companies invest in new filtering technology. Either known as coolant or cutting fluid, it is used to lubricate e cool parts during machining and is necessary due to the high volume demanded in the several machining operations and to the high cost of the product. Therefore, there is the need for recycling the product after its use. The work shows the technology and fundamentals of filtration as well as different filtering elements, filtration systems and scale contamination used in the industry. Also, there is a differentiation between filtration of the surface type (cake) and depth filtration and shows the basic theory of filtration by mathematic models in different operational conditions. Ultimately, project criteria for a coolant filtration system selection is shown followed by technical-operational details of a real vacuum filtration system and a case study aiming the operational cost reduction of the system

The objective of this study was to compare different resins and determine their matching color with Vita shade, also investigating the possibility of substitution among them and the correlation between the visual and spectrophotometry methods of color selection. The composite resin Tetric N-Ceram® shade A1 was used as light-control and color A4 as dark-control. For each material were prepared five 10 x 2 mm disks. Analyses were performed in a metamerism box by volunteers who ordered the specimens from the lightest to the darkest. The spectrophotometry was carried out using the spectrophotometer Vita Easyshade®. ∆E values were subjected to analysis of variance with 5% significance level. The Fisher exact test showed that there was no color match among the materials and the reference Vita shade. The possibility of substitution among the composites could not be established. The two methods are able to correctly differentiate the control resin A4 as distinct from the other resins shade A2.

Objective: to the purpose of this study was to compare the stress distribution in the peri-implant hard tissue on different attachment systems for mandibular or maxillary implant-retained overdentures. Material and methods: the search for published studies was performed on PubMed/Medline database covering the period of January 2000 to April 2014. The selection of the eligible studies was performed according to including and excluding criteria. Results: a total of 140 studies were screened and according to the search strategy, 21 studies were selected for this review. Eight studies perfomed strain-gauge analysis, 5 evaluated the stress distribution though photoelastic test and 7 performed tridimensional finite element analysis. Only one study in vivo was included. Non-splinted O-rings showed better stress distribution than other bar-clip attachment systems. Conclusions: the present study did not find sufficient evidences regarding the most indicated attachment system for overdentures with better stress distribution for the peri-implant hard tissue. The methodologies analyzed should be complemented with other tests and used as a tool for further clinical studies.

The aim of this study was to investigate the development of specific domains of Numerical Cognition (Number Sense – NS, Number Comprehension – NC, Number Production – NP, and Calculation – CA) in Brazilian children with Specific Learning Disorders. The study included 72 children (36 boys), from 9-to 10-years-old, enrolled in 4th and 5th years of elementary school of public schools at countryside of Sao Paulo State, Brazil. They were divided into three groups: control (CT, N = 42), Developmental Dyslexia (DL, N = 11) and Developmental Dyscalculia combined with dyslexia (DDc, N = 19). All participants had intellectual level within the normal range, however, children from the last two groups had Learning Disorders classified by School Achievement Test - TDE (Stein, 1994) and DDc children received necessarily classification as 'inferior' in Arithmetic Test of TDE. The children did not differ in NS. DL and DDc children showed slight deficits in NC. However, DDc children had moderate in NP and mild to moderate deficits in CA, which indicates a more generalized impairment in Numerical Cognition. Furthermore, DDc children showed discrepancy in Numerical Cognition performance when compared to the other groups. Thus, children with Learning Disorders showed different performances in Numerical Cognition, although both groups had preserved SN, DDc children showed higher deficits and discrepancy in relation DL and typically developing children.
