in this work, the time series modeling was used to predict the tazareh coal mine risks. for this purpose, initially, a monthly analysis of the risk constituents including frequency index and incidence severity index was performed. next, a monthly time series diagram related to each one of these indices was for a nine year period of time from 2005 to 2013. after extrusion of the trend, seasonali...

background: there is a high prevalence of  occupational injuries due to accidents in construction industries which affect human health. therefore, the exploration and analysis of contributing factors of such accidents can lead to their prevention and the reduction of their consequences. this study was conducted with the aim to identify factors related to occupational injuries and the severity o...

conclusions path analysis of occupational injuries based on the sem reveals that individual and organizational factors and their indicator variables are very influential on the severity of traumatic occupational injuries. so, these should be considered to reduce occupational accidents’ severity in large construction industries. materials and methods the present cross-sectional analytical study ...

Evidence from 32 studies that have evaluated the safety effects of median barriers, guardrails along the edge of the road, and crash cushions (impact attenuators) is summarized by means of a meta-analysis. Two hundred and thirty-two (232) estimates of safety effects are included in the meta-analysis. The presence of publication bias is tested by means of the funnel graph method. For most subset...

conclusions the seatbelt wearing rate among the study participants was much lower than the 90% rate reported among iranian drivers in 2010. mandating seatbelt use, as in most countries, will be more effective if a combination of factors such as changes in vehicle design, road safety, and driver and passenger behavior are taken into account. background seatbelts are a relatively low-cost safety ...
