Avaliação clínica e comparativa da oclusão balanceada bilateral e desoclusão com guia canino sobre a função mastigatória de usuários de prótese total removível

The maintenance of masticatory function is especially important for patients who wear complete dentures due to the limitations of this type of prosthesis. Thus, the bilateral balanced occlusion (BBO) is used to achieve, besides other advantages, greater masticatory efficiency. However, analyzing critically the literature, it is observed that there is not enough scientific evidence that support the BBO as the most appropriate occlusal concept in complete dentures. This way, the purpose of the present study was to verify if complete dentures wearers with BBO present better masticatory efficiency and capacity than those with canine guidance (CG). A double-blind controlled crossover clinical trial was conducted. The sample was made of 24 completely edentulous patients. The subjects wore sets of complete dentures with both occlusal concepts for equal periods of 3 months. Objective data were collected through the masticatory efficiency test, performed by the colorimetric method, in which capsules of a synthetic material enclosing fuchsine- containing granules were used. Subjective data were recorded by patient´s ratings of their chewing function, which is the masticatory ability. No significant statistical difference was found for masticatory efficiency (p=0,0952) and masticatory ability (x2=0,5711/ p=0,4498) between the two occlusal concepts studied, as well as there was no correlation between these two variables (p=0,2985). Based on these results, it seems reasonable to use CG for the setup of complete dentures, since it is an easier and quicker technical procedure, until that future researches can come to complement this question

Identificação e comparação entre controle preditivo com modelo não linear e PI sintonizados com PSO em sistema de separação gravitacional de águia-óleo

The separation methods are reduced applications as a result of the operational costs, the low output and the long time to separate the uids. But, these treatment methods are important because of the need for extraction of unwanted contaminants in the oil production. The water and the concentration of oil in water should be minimal (around 40 to 20 ppm) in order to take it to the sea. Because of the need of primary treatment, the objective of this project is to study and implement algorithms for identification of polynomial NARX (Nonlinear Auto-Regressive with Exogenous Input) models in closed loop, implement a structural identification, and compare strategies using PI control and updated on-line NARX predictive models on a combination of three-phase separator in series with three hydro cyclones batteries. The main goal of this project is to: obtain an optimized process of phase separation that will regulate the system, even in the presence of oil gushes; Show that it is possible to get optimized tunings for controllers analyzing the mesh as a whole, and evaluate and compare the strategies of PI and predictive control applied to the process. To accomplish these goals a simulator was used to represent the three phase separator and hydro cyclones. Algorithms were developed for system identification (NARX) using RLS(Recursive Least Square), along with methods for structure models detection. Predictive Control Algorithms were also implemented with NARX model updated on-line, and optimization algorithms using PSO (Particle Swarm Optimization). This project ends with a comparison of results obtained from the use of PI and predictive controllers (both with optimal state through the algorithm of cloud particles) in the simulated system. Thus, concluding that the performed optimizations make the system less sensitive to external perturbations and when optimized, the two controllers show similar results with the assessment of predictive control somewhat less sensitive to disturbances

Metodologia para gerenciamento de projetos em tecnologia da informação baseada no guia PMBOK: um estudo de caso na Secretaria de Estado da Saúde Pública do Rio Grande do Norte

Nowadays the search for growth makes organizations seeking competitive advantages, project management shares this goal, through techniques that assist in the search for an improved management of the various fields of knowledge through a design methodology. The world is driven by projects and the search for ways to better manage activities such as time, cost and term towards the success of a particular project is something constant. A major contribution that IT can make to the health sector is the support for the management area. IT can integrate processes, optimize the interconnection between the various sectors, make hospitals have access to inside information of good quality, as well as support in the healthcare area, sharing pictures, uniting the various aspects of nursing and nursing service. The major challenge faced by the SESAP Information Technology sector at present is in project management in IT , which does not exist makes investments in the area are increasingly difficult due to this deficiency in management develop their own systems without cost additional to the State. This study seeks to build and strengthen the Project Management within the Department of Health through the implementation of a project office that will manage the final result of this work methodology based on PMBOK, and still show the functionality applied to development the state Hospital Management System that will later be installed on all Regional Health Units and proposing measures for the sustainability and development of the sector amid the difficulties of the current public service. Such action will result in a savings of more than R$ 107,000.00 (one hundred seven thousand) regarding spending private software currently used by the assignment of invested by the State of Rio Grande do Norte user licenses, representing more than 5 % of the total budget of the State Department of Public Health of the State
