[ 1 ] - بررسی اثرات توام گرما و روشنایی بر روی زمان واکنش دانشجویان در شرایط آزمایشگاهی
Introduction: In many workplaces there is exposure to heat and light simultaneously. This study investigated the combined effect of heat and lighting on some cognitive performance, i.e. reaction time. Methodology: the present semi-experimental study was conducted 2015 on 33 healthy students (16 girls and 17 boys) with a mean age of 22.1 in the thermal stress chamber. The reaction time parame...

[ 6 ] - رابطه بین مواجهه با فیوم منگنز و بروز علایم سردرد میگرن در بین جوشکاران
Background: Welding generates complex metal aerosols, inhalation of which is linked to adverse health effects among welders. Exposure to manganese (Mn) fume in welding processes can have a harmful effect on welders’ health. Long-term, high-level exposure to Mn is associated with impaired central nervous system (CNS) function. The present study aims to investigate relationship between exposure t...
[ 7 ] - Investigating the relationship between the prevalence of carpal tunnel syndrome symptoms (CTS) and the dimensions of quality of life among computer users of 50 typing institutes
Introduction: Carpal tunnel syndrome is followed by pushing Median nerve in the carpal tunnel of the wrist. Occupational factors such as repetitive movements of the hands and fingers and frequent wrist disturbances affect the development of this syndrome. Quality of life is a multidimensional concept including physical and mental performance. The aim of this study was to determine the prevalenc...
