Along with the development of modern design technology and the increasing complication of modern engineering systems, component dependency has become a universal phenomenon during the failure analysis of systems. Ignoring the dependency among the failure behaviors of system components may lead to a huge error or even yield faulty results. In this paper, three types of models and two kinds of mo...

Calcium hydroxide, widely used in endodontic treatment, is a strong base that may cause irreversible injury to vital tissue that comes into contact with this substance. We present the first case of a dentist who accidentally splashed endodontic calcium hydroxide into her own eye. After washing with copious amounts of water for several minutes, she was treated in the hospital within 30 minutes o...

A 15-year retrospective study of 2228 civilian amputees was conducted at the Hospital for the Disabled, Thamaing, Rangoon. It was demonstrated that utilization of appropriate technology for development of essential components had enabled the hospital to serve more amputees. The ratio of male to female was 4.23: 1. The mean age was 31 years, male slightly older than female. Trauma was the leadin...

Statistical analysis of accident cases concerning dangerous goods was carried out in order to clarify the causes of the accidents. The results of this investigation will be useful for preventing similar accidents in the future. The number of dangerous goods accidents in Japan has been increasing, and the number of dangerous goods accidents reached a record high in the year 2000. Although variou...

Traditional research in construction safety focused on accident data analysis, identification of root cause factors and safety climate modeling. These research efforts did not study the dynamic repetitive interaction among multiple root cause factors. Recently safety research focuses on developing accident causation models. These models attempt to explain how the interaction among multiple proj...

In this study, general aviation accident records from the files of the National Transportation Safety Board (NTSB), have been analysed by gender to observe the number and rate of pilot-error related accidents from 1972 to 1981 inclusive. If both females and males have no difference in performance, then data would have indicated similarities of accident rates and types of injuries. Males had a h...

introduction: one cause of death among people aged under 40 is trauma which in increasing mainly because of increase in use of vehicles. there has been an increase in trauma and its mortality worldwide, resulting in lost of life years due to the consequent disabilities. however, we can prevent the mortality & complications due to trauma in particular, thorax trauma through intense & urgent care...

This study investigated workers' perceptions of workplace safety in an African work environment, specifically in Ghanaian work places. Workers' safety perceptions were examined with Hayes et al.'s. (1998) Work Safety Scale. Comparative analyses were done between high- and low-accident groups, and t tests were employed to test for differences of statistical significance. Relative to their collea...

BACKGROUND As one of the most frequently occurring accidents in a chemical plant, a fire accident may occur at any place where transfer or handling of combustible materials is routinely performed. METHODS In particular, a jet fire incident in a chemical plant operated under high pressure may bring severe damage. To review this event numerically, Computational Fluid Dynamics methodology was us...
