The fierce competitiveness of the current market and the sophistication of customer requirements made the commitment to quality a need within organizations. The search for quality has been carried out by the adoption of quality management systems, a formal organization that should be present throughout the organization, from the initial identification of market needs to the satisfaction of customer requirements. The methodology most commonly used for this purpose is based on the requirements of ISO 9001, latest version of 2008. Considering this scenario, was developed a case study in a small company of the industrial sector with the development of a plan for the implementation of ISO 9001. The proposed methodology involved the construction of a theoretical framework on the subject and the development of a case study with a qualitative approach. Initially, was applied a questionnaire to the representative of the organization about the company's operating procedures, activity logs held, current documentation, planning and resource management for the construction of an assessment about the adequacy of the company needs to ISO 9001. Were obtained as results the characterization of production processes and organizational structure of the company and examples of policy and objectives of quality, performance indicators, document control, system for visualization of non-compliances, among others. Finally, the benefits of adopting a quality management system based on ISO 9001 requirements for the company and its environmental issues such as increased process efficiency, less waste and greater profitability, were pointed out, and the conditions for effective certification in the future

The aim of his study was to review the current scientific literature in order to discuss the surgical, prosthetics and psychological/psychosocial aspects during the treatment planning of edentulous patients, when a total fixed prosthesis or overdenture is indicated. To identify studies to take part in this review, a search was conducted for the following databases: PubMed, Dentistry and Oral Sciences Source, Journals@Ovid, SpringerLink, Wiley Online Library, Nature (NPG), Oxford Journals. It was used as descriptors: total fixed prostheses and overdentures. Inclusion criteria were: clinical articles, clinical case reports, case series, literature reviews and systematic reviews that addressed the study and comparison of total fixed prostheses and overdentures for a surgical- prosthetic planning. Exclusion criteria were: laboratory and in vitro studies and those whose first language was not English or Portuguese. Of a total of 454 articles, after an analysis according to inclusion and exclusion criteria, 76 articles were selected. During an implantsupported prosthesis rehabilitation with dental in edentulous patients, the use of alternative procedures appear to be effective when compared to more invasive surgical techniques, and thus, the amount of dental implants possible to install associated with prosthetic issues such as lip support, smile line, quantity and quality of mucosa, phonetics, etc., will allow an appropriate treatment planning to each clinical case

The oral rehabilitation has achieved great prominence in the dental implant, especially in the cases of reposition of units dental elements, so it is possible to replace each missing element to implant into your space where the tooth was loss. The reverse planning is fundamental to an appropriate rehabilitation, because promote the elimination of problems that might compromise the aesthetics and function of future dental implants. The objective of this study was to report the treatment plan for a patient in need of oral rehabilitation with implant dental prosthesis, using indications and techniques based on the literature, emphasizing the importance of reverse planning. We conducted an osseointegrated implant surgery using the principles of a connect procedure, thus allowing their successfully installing increasing the predictability of treatment. It is concluded that the success of rehabilitation treatment is directly related to the initial planning, a correct clinical approach and an integrated multidisciplinary team.

The present article describes the treatment planning and fabrication of overlay denture to restore the jaw relationship in a partial edentulous patient with bruxism. A male patient, 51 years old, was referred to the oral rehabilitation clinic complaining about the chewing and aesthetic. The occlusal surface of the superior teeth presented severe wear. The fabrication of an interim overlay denture to restore the jaw relationship was planned. The overlay had metallic projections and covered the occlusal surface of superior teeth. After overlay insertion both function and aesthetic of the patient were recovered. It was concluded that the use of overlay improved the physiological normal position of the jaw and could provide a favorable prognosis for a definitive oral rehabilitation with implant-supported fixed denture.

This work had with objective to characterize and evaluate the performance of the combined system, involving activated charcoal and ionic exchange resins in the removal of substances organic contaminating of the ethyl alcohol from the fermentation of the cassava starch. To testing was used ethyl alcohol PA 96 oGL, conductivity of 0.90 μS/cm at 25 oC, acidity of 60 mg/L and Barbet test of 43 minutes at 15 oC. The contaminated alcohol was composed of ethyl alcohol additive of higher alcohols, organic acids, ester, diol, aldehydes, ketone and ether. Contaminated alcohol was added 2% activated charcoal and after the adsorption isotherm in ionic exchange resins was tested. The adsorption with activated charcoal was performed in a Water Bath at 30 oC for one hour and a half and shaking. Already adsorption ionic exchange columns occurred at room temperature on columns of 93,4 cm in filling height and diameter of 2.29 cm, for flows of 180 mL/min and 90 mL/min. Samples were collected in the tests with charcoal and with each one of the resins and the following analyses were performed: conductivity, acidity and Barbet test. The medium values for conductivity, acidity and Barbet test after the adsorption in charcoal and cation and anion resins were respectively: conductivity was 240; 354 and 465 μS/cm to 25 oC; acidity of 1.081; 1.103 and 1.062 mg/L and the Barbet test was 21; 20 and 9 minutes to 15 oC. It was observed that the addition of 2% of activated charcoal and the permanence in the columns of adsorption was not sufficient to remove the organic substances contaminating of the ethyl alcohol.

The objective of this paper is to show the development of a Geographic Information System (SIG) for the management of the Educational Centers of the city of Bauru. Currently, the Educational Centers and Assistance Institutes, public or private, in Brazilian cities have some problems, for example: they have no money to manage their institutions and they have no correct form to organize and to store the information. Because of these problems, we developed a system which will manage some informations for these institutions and local authority. This system will allow visualizing the data in the internet by the community. This pilot project has used the softwares SPRING 4.1 e SPRINGWEB 3.0.

Educational games are responsible for part of the information assimilated by the child, because these games respect the individual learning time, enabling experimentation and, consequently, being an accessory to retain the acquired knowledge spontaneously. However, the analogy between stimulus and reception/result is not always the expected. On the one hand, there are the pedagogues, bearing the knowledge necessary to the children’s development. On the other hand, are the children, who cannot completely assimilate the concept, commonly because of lack of planning on the product. After all, the children become not interested in the game, without developing the expected cognitive abilities planned for the product. Whereas the importance of the games on children’s development, this work aimed to analyze and select educational games presented on the preschool, based on the language exploration from the Design’s knowledge and skills. Specifically, the research intends to investigate games targeted to stimulate geometric concepts, and so, to describe parameters that must be observed during the product planning.

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.
