국내외의 가연성 또는 인화성물질을 취급하는 대형설비에서의 폭발위험장소에 대한 안전관리는 기업의 지속가능경영과 신뢰를 바탕으로 한 지역사회와의 공존에 있어 매우 중요하다. 폭발위험장소의 안전관리는 크게 가연성 또는 인화성 물질의 누출을 제어하는 시스템과 이러한 가연성 또는 인화성물질이 누출되어 폭발분위기를 형성할 때 점화원을 제어함으로써 화재 또는 폭발사고로 전이되지 않도록 하는 방폭시스템이 있다. 제도와 기술로 인해 전기적 점화원에 대한 방폭설비는 상당히 보급되어 관리되고 있다. 하지만 열적 점화원의 경우, 위험성에 대한 인식과 관련 기술개발이 미흡하다. 본 연구는 잠재적 폭발위험장소에서 내연기관의 점화 위험을 보고하기 위하여 수행되었다. 이를 위하여 문헌조사를 통하여 관련 국제표준과 사고사례 및 위험분석보고서를 연구하고, 국내 중부권 공정안전관리제도 대상 사업장의 디젤엔진의 불꽃방지기 등 안전장치 적용실태를 조사하였다. 실제적으로 본 연구결과를 석유화학 산업에 적용함에 있어, 디젤엔진과 같은 내연기관 점화원의 위험인식을 통해 잠재적 폭발위험장소에서의 폭발방지에 대한 안전관리방안으로 활용 될 수 있을 것이다.

'Aviation Safety' is the state in which the risk of harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management in the aviation field. 'Risk' is the assessed potential for adverse consequences resulting from a hazard and 'Risk assessment' involves consideration of both the frequency and the severity of any adverse consequence. This study focused on the risk frequency about a case airport which does not meet the 'Runway end safety area' requirement of ICAO SARPs and Korea standards and used 'RSA risk model' for estimating the risk frequency. As results of this study, risk frequency of the runway end safety areas in the case airport is higher than that of 'Runway end safety area' requirement of ICAO SARPs and Korea standards, which means that alternatives for risk frequency mitigation to a level as low as reasonably practicable is required in the case airport. The optimum solution analysed from this study is to impose restriction of aircraft operation when the runway condition is poor(icing condition) and also it snows in the case airport.

This study aims to establish safety zones for bunkering operations of hydrogen propulsion ships in coastal areas through risk assessment and evaluate their validity. Using a 350 kW-class ferry operating in Busan Port as the subject of analysis, with quantitative risk assessment based on accident consequence and frequency analysis, along with a social risk assessment considering population density. The results of the risk assessment indicate that all scenarios were within acceptable risk criteria and ALARP region. The most critical accident scenarios involve complete hose rupture during bunkering, resulting in jet flames (Frequency: 2.76E-06, Fatalities: 9.81) and vapor cloud explosions (Frequency: 1.33E-08, Fatalities: 14.24). For the recommended safety zone criteria in the 6% hose cross-sectional area leakage scenario, It could be appropriate criteria considering overall risk level and safety zones criteria for hydrogen vehicle refueling stations. This research contributes to establishing safety zone for bunkering operations of hydrogen propulsion ships through risk assessment and provides valuable technical guidelines.

A survey of risk perception in South Korea was conducted in 2007 to evaluate relative riskiness of typical industrial and technological risks. This article summarizes the characteristics of risk perception using psychometric analyses. The survey with a sample size of 1,194 reviews the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, nuclear power generation, and newly-introduced risks. Six categories of risk identified by a factor analysis show that the level of perceived risk does not correspond to the statistical level. Psychometric analyses including voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity demonstrate that voluntary, familiar and immediate risks are perceived as less risky than involuntary, unfamiliar and delayed ones. Risk communication is critical in reducing the discrepance between objective and subjective level of risk. However, the amount of risk information does not always justify a successful risk communication. A safety policy, risk communication strategy in particular, should take into account diverse dimensions of risk reviewed by psychometric analyses in the study. Social policy toward safety can be improved by integrating policy, human, and social factors as well as technological advances.

Purpose: This study was done to compare health risk behavior prevalence for youth living in metropolitan, medium sized and small cities or rural area, in order to enhance understanding regional differences. Methods: For this study, data from the 2006 Youth Health Risk Behavior Online Survey collected by the Korean Center for Disease Control were analyzed using SPSS. Results: In the metropolitan areas, prevalence for disease and perceived obesity were higher than in other areas. Lack of intense or moderate physical activity, obesity, fast food intake, and insufficient sleep showed higher prevalence than in rural areas. Prevalence of lifetime smoking, lifetime alcohol consumption, present alcohol use, fruit intake less than once a day, and not wearing a seat belt were higher in rural areas than in urban areas. Gender, smoking, and alcohol use were correlated. Spearman correlation between living with parent and skipping breakfast were significant. Smoking, alcohol use, and sexual behavior were correlated. Conclusion: As significant differences in prevalence of youth health risk behaviors exist between regional areas, health education and health promotion programs considering these differences have to be developed and implemented for adolescents. Programs for prevention of smoking and alcohol use, programs for improvement of fruit intake and safety are suggested for adolescents in rural areas, whereas programs to enhance physical activity and obesity management are suggested for adolescents in metropolitan areas.

PURPOSES : This study was conducted to develop expressway safety treatments based on the analysis results of older driver behaviors through literature review, surveys, and driving simulator experiments. METHODS : In this study, three analyses were conducted: surveys of 700 older drivers to find the risk segments they recognized, driving simulator experiments with older and younger drivers to investigate driver behaviors, and expert surveys to find the priority of expressway safety treatments for older drivers. RESULTS : Through survey results it was found that merging areas and tunnels were identified as the most dangerous areas, and more dangerous older driver behaviors were observed on those expressway segments in the driving simulator experiments. In addition, the priorities of safety treatments for each segment of expressways were decided based on expert surveys. CONCLUSIONS : It was concluded that choice and concentration strategies of expressway safety treatments for older drivers should be applied as perceptions regarding dangerous spots and older driver behaviors, including geometric designs, safety facilities, regulation, and institutes to improve expressway safety.
