[ 2 ] - بررسی همبستگی دو شاخص استرس حرارتی دمای تر گویسان (WBGT) و حد کار گرمایی (TWL) در مقایسه با حد مجاز اصلاح شده دمای پرده صماخ
Introduction: Thermal stress risk management requires the development of applied indicators. The purpose of this study was to evaluate the performance of the two indicators including WBGT and TWL and their fit with the tympanic temperature. Method: This cross-sectional study was carried out on 101 urban service personnel in a heat and dry area in 2016. The measurements of the study indices inc...
[ 3 ] - Assessment of Job Stress and Personal-Related Factors among the Workers of a Military Industry
Health of organization’s employees is dependent on psychosocial factors such as job stress, considerably. Job stress is related to the low quality of life, job burnout, increasing the risk of accidents and work–related injuries and cause job change and early retirement of employees. This study aimed to evaluate employees’ job stress in an industry as well as to assess its relationship by person...

[ 6 ] - Regression Models of Some Anthropometric Dimensions Based on Stature: A Case Study among Students 18 to 26 Years
Abstract Background and Purpose Anthropometric data is an essential part of the ergonomics design of the equipment, environment and work. Using anthropometric information, designers will be able to design appropriately the needs of the dimensional characteristics of the target group. According to studies, the structural characteristics of the human body are influenced by factors such as ra...
[ 7 ] - Investigation of the compatibility of wet bulb globe temperature (WBGT) and predicted heat strain (PHS) in assessing the environmental conditions and heat load imposed on individuals: a case study in bakery workers
Introduction: This study was designed with the main purpose of examining the compatibility of the two indicators of wet bulb globe temperature (WBGT) and predicted thermal strain (PHS) in assessing the environmental conditions and the heat load imposed on the subjects. Method: In this cross-sectional study, 163 bakers were included in the study. Thermal stress was determined using the WBGT and...
[ 8 ] - Modeling and Optimization of Arsenic (III) Removal from Aqueous Solutions by GFO Using Response Surface Methodology
Arsenic is a highly toxic element for human beings, which is generally found in groundwater. Dissolved Arsenic in water can be seen as As+3 and As+5 states. The adsorption process is one of the available methods to remove Arsenic from aqueous solutions. Thus, this papers aims at removing Arsenic (III) from aqueous solutions through adsorption on iron oxide granules. The relation among four inde...
