The steel pipe manufacturing industry deals with facilities and materials. Especially thermal facilities are close to vapor cloud explosion (VCE) and may cause secondary damage to facilities because they deal with corrosive substances such as hydrofluoric acid, sulfuric acid and acid, fire, explosion, leakage etc. It is in danger. In this study, hazard identification method was conducted using HAZOP techniques and quantitative risk analysis was conducted using e-CA, a program that supports accident impact analysis. Equipment in the influence range of ERPG - 3 was determined to be a facility requiring replacement. It was decided that neutralization is necessary using slaked lime. Based on the cost of loss, We presented the proper replacement which is the timing of the dangerous facility. As a result, It was ideal to replace the facilities with 20 years of heat treatment facilities, one year of hydrofluoric acid storage tank, 20 years of sulfuric acid storage tank, and 5 years of hydrochloric acid storage tank.

도심과 사회기반시설의 확장에 대한 수요로 인해 군사시설의 이전이나 시설의 지하화가 지속적으로 요구되고 있다. 그러나 탄약시설과 같은 시설을 횡단할 때에는 탄약이 우발적으로 폭발하지 않도록 고도의 안전성 평가가 선행되어야 한다. 이에 지중 구조물의 건설을 위한 발파작업이 지상의 탄약시설에 미치는 영향을 분석하기 위해 국방부와 한국철도시설공단간 협의에 의해 진행되는 신안선 복선 전철 설계구간 중 군사 보안구역을 통과하여 건설되는 터널구간에 대해 사례연구를 실시하였다. 폭발현상에 의한 진동의 속도를 수치해석 프로그램인 GTS-NX를 활용하여 예측하였고 문헌조사를 통해 모든 형태의 구조물에 대해서도 안전에 영향을 미치지 않는 0.2cm/sec의 지반진동속도를 안전성 평가기준으로 제시하였다. 본 연구에서 활용된 안전성 평가지표와 절차는 향후 탄약시설을 횡단하는 사회기반시설 계획 시 안전성 평가의 지표로 활용될 수 있을 것이다.

The International Atomic Energy Agency (IAEA) entails independent decision-making for the safety supervision of civil nuclear facilities. To evaluate and review the safety of nuclear facilities, the national regulatory body usually consults independent institutions or external committees. Technical Support Organizations (TSOs) include national laboratories, research institutions, and consulting organizations. Support from professional organizations in other countries may also be required occasionally. Most of the world's major nuclear power countries adopt an independent nuclear safety supervision model. Accordingly, China has continuously improved upon the construction of such a system by establishing the National Nuclear Safety Administration (NNSA) as the decision-making department for nuclear and radiation safety supervision, six regional safety supervision stations, the Nuclear and Radiation Safety Center (NSC), a nuclear safety expert committee, and the National Nuclear and Radiation Safety Supervision Technology R&D Base, which serves as the test, verification, and R&D platform for providing consultation and technical support. An R&D system, however, remains to be formed. Future endeavors must focus on improving the technical support capacity of these systems. As an enhancement from institutional independence to capability independence is necessary for ensuring the independence of China's nuclear safety regulatory institution, its regulatory capacity must be improved in the future.

As a mass transportation system, a railway contains potential risks that may result in a high death rate and property losses. Accordingly, Railroad Safety Technology R&D Corps. is adopting the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective project management methods with Systems Engineering techniques. When a system or a service is realized, such as the Railway Total Safety Project, it needs to be verified by requirements and the process of verification is to check whether customers/stakeholders requirements have been properly transformed into a system or a service. Recently, building the standardized verification system up could be the solution to reduce possible system-failed risks. To support that, we propose the more effectual verification method of constructing the Railway Safety Test Facilities applying the systems engineering tool to the research.

To verify the performance of roadside safety facilities, strength and occupant protection test are performed by evaluation criteria. Strength test use a truck and occupant protection test use a sedan. Strength perfomance is analyzed pass rate by post lateral resistance of the safety barrier. Occupant protection performance is analyzed from THIV(Theoretical Head Impact Velocity) and PHD(Post-impact Head Deceleration) by crash cushion test.

The purpose of the study was to investigate the relationships between dietitian’s job satisfaction and perception of barriers to HACCP implementation and food safety/sanitation management performance in school food service. An e-mail survey was conducted to 144 dietitians in Gyeongbuk Province. A response rate was 57.6%(N=83) and data were analyzed using SPSS Windows(ver. 10.0). Dietitians were more satisfied with ‘supervision’ and 'co-workers' than 'pay' and 'promotion.' Dietitians perceived 'lack of teachers' support on student education' and ‘limited availability of facilities/equipment' as the biggest challenges in implementing a HACCP system. A total score of sanitation/safety management performance evaluated by school districts was 92 out of 100. By category, 'safety management' and 'personal hygiene' were rated the highest whereas 'facilities/equipment' and 'HACCP system' categories were rated the lowest. The food sanitation/safety management performance scores were not correlated to dietitian’s job satisfaction, but significantly correlated to dietitian’s perceptions of barriers to HACCP implementation. As dietitians perceived facilities/equipment-related barriers greater, the scores of 'facilities/equipment(p<.01),' 'production process(p<.05),' and 'total score(p<.01)' were significantly lower. The findings suggest that more investment on facilities/equipment are needed for food safety improvement and successful HACCP implementation in school food service. Proper facilities and equipment will make employees monitor CCPs and take corrective actions more easily.

It has been applied several ways in order to prevent traffic accidents and speed management on the road which is one of very important factors to prevent accidents. In this study, it is analyzed whether the facility such as the flashing and crosswalk, speed cameras and intermittent warning signs affect on a driving deceleration or not. It has been shown that the flashing and crosswalk and speed cameras except intermittent warning signs play a role of reducing the driving speed. The result showed that these traffic safety facilities help to improve the average speed as well as velocity distribution which was derived by the speed deviation even if there were the difference between facilities. Speed limit display does not affect the deceleration of the driver. Therefore, it was founded in this research that there were the driving speed reduction effect due to the facilities on the road. In order to control the driving speed on the road, it is necessary to install facilities with appropriate location and spacing on the road. In addition, place that turns out suppressed speeding through speed management also are required adequate facilities such as speed cameras.
