background and objective: obstructive sleep apnea (osa) is the most common respiratory disorder during sleep and a risk factor for myocardial ischemia. in this study, we evaluated the proportion of subjects at high risk for osa and prevalence of its predictors among patients admitted for acute myocardial infarction (mi). materials and methods : a total of 210 patients with mi admitted at the ca...

conclusions our results showed that the study population perceived a high likelihood of cchf risk. improving public knowledge and awareness could result in a more realistic assessment of cchf risk, hence better compliance with taking precaution measures to tackle the disease. results approximately 70% of the respondents reported the cchf risk to be 'high'. factors independently associated with ...

this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

Rabin [23] proved that a low level of risk aversion with respect to small gambles leads to a high level of risk aversion with respect to large gambles. Rabin’s arguments strongly depend on expected utility theory, but we show in this paper that similar arguments apply to many non expected utility theories, and to a certain extent, to theories dealing with uncertainty as well.

 Background: The aim of this paper was the comparison of ergonomic risk assessment results (final score and action levels) for the entire body as determined using Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA).  Materials and Methods: This was a cross-sectional study in which all 82 workers engaged in various processes with different activities in an anodizing a...
