The Effect of Train Motion on Current Collection in High-speed Train
Kim, Jung-Soo ;
International Journal of Safety, volume 5, issue 1, 2006, Pages 1~4
The safety performance of the current collection system is evaluated by conducting a test run in which accelerometer and load cell signals are analyzed. It has been found that the current collection performance is strongly influenced by the train speed, with the major frequency components arising from the train traversing the span spacing and the 8.5 Hz component originating from the panhead resonance. The train acceleration is found to have significant influence on the span passing frequency but negligible effect on the resonant response.
A Study on Effect of Risk Survey Using CATIA V5 Program for Loss Prevention

International Journal of Safety, volume 5, issue 1, 2006, Pages 5~9
The present study reports on the results of a risk survey of machinery safety at a shoe factory in Qingdao, China. The aim is to decrease industrial accidents and increase worker job satisfaction by searching for a change from a trend analysis and making improvements in problem areas. The first risk survey for machinery safety was carried out in April 2005. Based on the analysis of the survey results, machinery safety devices was installed in the factory by using CATlA V5. Also, we investigated job satisfaction concerning working apparatus and work tool improvement in a questionnaire about the working environment. The second survey of machinery safety was carried out in September 2005. We are in the process of comparing the first survey results with the second survey results in order to analyze decreasing trend in industrial accidents and improvement in job satisfaction. So far the data have shown improved short-term turnover and absenteeism. It means CATIVA V5 and CFR has had positive effect regarding safety in shoe manufacture industry. The survey with CATIVA V5 and CFR will be expanded to other East-Asian countries including Vietnam. The hope is that the present approach could make a significant contribution toward improved safety.

A suspended hemispherical silicon asperity moving over a silicon plate was simulated. The simulation results on friction and wear in the interface between the two can help obtain more durable miscroscale structures. Silicon structures were constructed with Tersoff three-body potential. Dependence of friction and wear of the asperity on both the atomic arrangement in the plate and the moving direction was investigated under the condition that the asperity is subject to the attractive normal force due to the plate. The results show that the variation of friction force with the movement of asperity, and the occurrence of adhesive wear are attributed to the formation and rupture of asperity, junction between the asperity and the plate. The friction force and wear are smaller when the asperity is incommensurate with the plate, and they also depend on the moving direction of the asperity over the plate.
Study on Coupled Resonance Frequencies and Acoustic Responses in a 3-D Acoustic Cavity with the Air-gap for Safer Driving Condition
Kang, Sang-Wook ;
International Journal of Safety, volume 5, issue 1, 2006, Pages 17~23
An investigation was carried out to determine the effect of the thickness of the air-gap installed between the roof metal sheet and the headliner on booming noise in passenger cars. In addition, a way of offering quieter driving condition to drivers and passengers was studied. It was found that a very thin air-gap corresponding to approximately 3/100 of the height of the passenger compartment causes noticeable change in the coupled resonance frequencies and acoustic responses. Furthermore, a guideline is proposed for determining an optimal air-gap thickness during design stage of the air-gap beneath the roof metal sheet for reducing booming noise.
Role of Certification and Supervision in Safety Management of Elevators
Choi, Gi-Heung ;
International Journal of Safety, volume 5, issue 1, 2006, Pages 24~28
This study focuses on the issue of improving safety management of elevators. The role of certification and supervision in reducing the associated accidents is specifically addressed. The results of simple statistical analysis suggests that a certification procedure emphasizing the quality assurance during manufacturing and supervision during assembly and installation of elevators are needed and can be effective in minimizing the associated accidents.

There has been an increasing need for substitute energy development due to the dry up of the fossil fuel and environmental problems. Among the substitute energy under consideration, producing hydrogen from water without the accompanying release of carbon has become a promising technology. Also, Iodine-Sulfur (IS) thermochemical water decomposition is one of the promising processes that can produce hydrogen efficiently using the high temperature gas-cooled reactor (HTGR) as an energy source capable of supplying heat at over 1000. In this study, to effect an initiating events identification of the IS process, Master Logic Diagram (MLD) was used and 9 initiating events that cause a leakage of the chemical material were identified.
A Study on Status Laboratory Safety and Improvement According to the Safety Consciousness Survey of University Students in Korea

In laboratories, researchers frequently work using new methods with new tools and materials. So the workers in laboratories are exposed to risk from dangerous articles all the time. In the case of university laboratories, testing is done by the individual at night. Because of that, the risks in university laboratories are higher than in other places. In addition, students and managers in universities generally have little concern for laboratory safety. So students are sometimes injured or killed in laboratory accidents. In this study, 1,000 university students answered questions about university laboratory safety. Their answers have been analyzed to determine the state of actual conditions and to formulate countermeasures. The results indicate that we need to change the safety awareness of the universities and the students. Adequate safety training and safe practice must be implemented by each university to decrease accidents. Development of systematic safety training program suited to the specific conditions of the individual laboratory and formulation of specific counter plans should accidents occur are required.

The major objective of the statistical analysis about industrial accidents is to determine the safety factors so that it is possible to prevent or decrease the number of future accidents by educating those who work in a given industrial field in safety management. So far, however, there exists no quantitative method for evaluating danger related to industrial accidents. Therefore, as a method for developing quantitative evaluation technique, this study presents feature analysis of industrial accidents in manufacturing field using QUEST algorithm. In order to analyze features of industrial accidents, a retrospective analysis was performed on 10,536 subjects (10,313 injured people, 223 deaths). The sample for this work was chosen from data related to manufacturing businesses during a three-year period (
) in Korea. This study used AnswerTree of SPSS and the analysis results enabled us to determine the most important variables that can affect injured people such as the occurrence type, the company size, and the time of occurrence. Also, it was found that the classification system adopted in the present study using QUEST algorithm is quite reliable.
