Health care institutions seek to increase their cost to benefit ratio regarding the purchase of a MD, without compromising the patient's health. Mechanical characterization is an excellent way to measure important physical properties to check the state of reused MD. Nevertheless, this type of analysis requires the destruction of the MD. This work attempts to approach this problem through the implementation of a nondestructive technique known as indentation by Shore A (hardness measure), that can be relate with deformation (Young's Modulus) through analytical models. This research reports that the relationship between the Young's Modulus and the electrosurgical pencils hardness follows a parabolic model among other models, including a multivariate model, a logarithmic model and an exponential one. We conclude that it is possible to obtain the value of the deformation of a MD through the measure of hardness, achieving to validate the mechanical behavior without destroying it, increasing the cost to benefit ratio of the health care institution and securing the patient's integrity during a medical procedure.","PeriodicalId":196438,"journal":{"name":"2014 Pan American Health Care Exchanges (PAHCE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126850104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the early detection of any possible postural alteration is essential in avoiding further adult life complications. There are several methods and instruments for feet evaluation; however, they are generally restricted to clinical environments, and are not appropriate for daily evaluations. We propose a system for feet alterations classification, for children with ages between 6 and 10 years, daily use, and based on latex insoles with pressure sensors and accelerometers. Our system uses a microcontrolled circuit connected to the insole, with a module for signals storage. For classification, the system uses an artificial neural network (ANN). In preliminary tests, a user applied specific plantar pressure distributions, for training the ANN. The ANN achieved 100 % of correct classifications for the signals used during training, and 96 % for the remaining signals. We also created a visualization of feet pressures during walking, in order to conduct a dynamic analysis of pressure distributions. The results suggest that system can classify feet and walking types. We will now conduct more systematic tests with more volunteers, to statistically evaluate the results.","PeriodicalId":196438,"journal":{"name":"2014 Pan American Health Care Exchanges (PAHCE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122073169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular the air pollution encompassing PM10 and smaller particles significantly contributes to the prevalence of respiratory diseases. Specifically, the city of Mexicali with a PM10 ranking of 137 in 2010 is considered as the most polluted city in Mexico largely due to the contribution of unusual environmental factors. Resulting respiratory abnormalities are often reflected in peculiar auscultatory indicators and their assessment can be accomplished using low cost technologies. These economic aspects are critical not only in Latin America but also other population centers globally considering the limited level of health services. Any classification of auscultatory indicators as reflected in lung sound (LS) characteristics needs to account for a noisy environment and the influence of heart sounds (HS). The aim of these studies was to utilize Hidden Markov Models (HMM) in light of the previously conducted assessment of lung sounds (LS) utilizing the Mixture Gaussians Models (GMM). In particular, the application of HMM models provides robustness to cope with noise and other interferences, to which the Mixture Gaussians Models (GMM) are more vulnerable. The conducted studies document that presented quantitative assessment of LS may add in more objective and economic scanning for respiratory abnormalities.","PeriodicalId":196438,"journal":{"name":"2014 Pan American Health Care Exchanges (PAHCE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123826828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
