Prevalence and Correlates of Cognitive Impairment among the Elderly in a General Hospital

Aims: To estimate the prevalence and correlates of cognitive impairment (CI) among the elderly in a general hospital. Methods: A cross-sectional study, including 200 Brazilian inpatients aged 60 years or over, using the Mini Mental State Examination to evaluate CI (dependent variable), and the Geriatric Depression Scale and the Katz and Lawton Index to evaluate basic (BADL) and instrumental activities of daily living (IADL). Results: 56% were women, 29% were dependent for BADL and 77.5% for IADL. The prevalence of CI was 29% and, in the logistic regression, it remained associated with higher age (1 74 years old), number of previous hospitalizations (1 3) and dependency for BADL (being dependent raised the odds of being cognitively impaired). Conclusions: It is essential to train the hospital staff to properly assist these patients, and to orient and support their caregivers. Copyright (C) 2009 S. Karger AG, Basel

An application of neural network technique to correct the dome temperature effects on pyrgeometer measurements

This work describes an application of a multilayer perceptron neural network technique to correct dome emission effects on longwave atmospheric radiation measurements carried out using an Eppley Precision Infrared Radiometer (PIR) pyrgeometer. It is shown that approximately 7-month-long measurements of dome and case temperatures and meteorological variables available in regular surface stations (global solar radiation, air temperature, and air relative humidity) are enough to train the neural network algorithm and correct the observed longwave radiation for dome temperature effects in surface stations with climates similar to that of the city of São Paulo, Brazil. The network was trained using data from 15 October 2003 to 7 January 2004 and verified using data, not present during the network-training period, from 8 January to 30 April 2004. The longwave radiation values generated by the neural network technique were very similar to the values obtained by Fairall et al., assumed here as the reference approach to correct dome emission effects in PIR pyrgeometers. Compared to the empirical approach the neural network technique is less limited to sensor type and time of day (allows nighttime corrections).

Trainer for Kids (T4K), um único aparelho para o tratamento de dois problemas verticais: mordida aberta anterior e mordida profunda

The Trainer for Kids is a prefabricated funcitonal appliance indicated for early treatment of the Class I malocclusion, crowding, anterior open bite, deep bite and oral habits (finger and/or sucking, atypic deglutition, tongue interposition and oral breathing). The aim of this paper is show two case reports treated with the T4K appliance being an anterior open bite and a deep bite.

Multinodal Load Forecasting in Power Electric Systems using a Neural Network with Radial Basis Function

In this paper we present the results of the use of a methodology for multinodal load forecasting through an artificial neural network-type Multilayer Perceptron, making use of radial basis functions as activation function and the Backpropagation algorithm, as an algorithm to train the network. This methodology allows you to make the prediction at various points in power system, considering different types of consumers (residential, commercial, industrial) of the electric grid, is applied to the problem short-term electric load forecasting (24 hours ahead). We use a database (Centralised Dataset - CDS) provided by the Electricity Commission de New Zealand to this work.

Automatic identification of terpenoid skeletons by feed-forward neural networks

Feed-forward neural networks (FFNNs) were used to predict the skeletal type of molecules belonging to six classes of terpenoids. A database that contains the (13)C NMR spectra of about 5000 compounds was used to train the FFNNs. An efficient representation of the spectra was designed and the constitution of the best FFNN input vector format resorted from an heuristic approach. The latter was derived from general considerations on terpenoid structures. (c) 2006 Elsevier B.V. All rights reserved.

As configurações do futebol brasileiro: análise da trajetória de um treinador

The present article is set to analyze the career of a soccer coach, highlighting information that may be assist in the discussion on graduating and professional actuation in Physical Education and Sports. The research, qualitative, used Life History as a method of data collection. To elucidate and articulate issues raised was used concepts from sociological theory of Norbert Elias. From the explicit path and the proposed configuration of Elias, we conclude that the figure of the trainer was formed as a result of interdependence established within the specific groups which took part, enriched by the academic.

A percepção do preparador físico sobre o estresse no futebol: um estudo piloto

Studies on stress in the sport are broad and profound. However, we do not found approach to study the perceptions of trainers on the subject and how it influences the organization of training throughout the season. From this premise, the aim of this work is to verify that the perception of the trainer about stress and its influence on planning. To this end, we chose a qualitative research, through an open interview, carried out with a trainer for a professional soccer team as a pilot for future studies. The interview responses are consistent with the findings of the literature on the changes in the players arising from the interference of stress in the various dimensions. But it was also possible to identify the trainer interviewed pointed out that stress, especially during the competition changes the preliminary planning, therefore, modify the activities to be applied to players depending on the outcome of matches. This pilot study we subsidized the development of new questions that will be inserted in the continuity of the study

Análise estrutural do suporte de pastilha de grafite para lubrificação de roda ferroviária

This study aims to structurally evaluate a support of graphite pastille for the lubrication of railway wheels. The proper lubrication of wheel flanges of the railway extends the life of this component, so it is very important that this occurs lubrication to reduce the costs involved in railway maintenance. To prepar the evaluation structural will be used to International Electrotechnical Comission standard (IEC 61373) establishing which load cases should be applied to this component. The applied loads on the support (accordance with IEC) are random accelerations and accelerations due to shocks, thus simulating the conditions that exist along the route of the train. The structural analyzes are performed by the finite element method, with the aid of the Cosmos software. Thus, it is possible to determine the stresses acting on the support, and so the allowable stresses compared with the standard proposed by the AISC. The stress in the structural analyzes are lower than allowable therefore considered for the configuration presented, unexpected structural problems
