In the chemical process industries, accidents have a high potential and large effects on catastrophic results. Therefore the safety management for accident prevention plays a crucial role to guarantee the process safety. For these reasons, many systematic methods for safety management system have been widely employed in the fields of chemical processes. PSM (Process safety management) is one of most representative methods. The audit system, which is one of PSM system components, evaluates the performance of PMS system. However, most existing safety audit systems are not systematic and these are performed based on knowledges and experiences of various specialist. Moreover, the safety audit is only performed based on each independent technical component. So, the results of safety audit are not a quantitative index but only a series of commentaries. Finally, it is very difficult to obtain the comparison with other plants or industries. In this study, the novel systematic method and index-based accident database of auditing safety management systems for quantitative assessment are proposed. First, the elements of safety audit replace technical methods to categories of accident database. The F-N curve of each category for accident database is employed to derive the index for quantitative assessment. The Accidental Factor Risk Index (AFRI) is suggested for evaluating the effect of each element in accident database and safety audit system. The safety audit can be modified according to the proposed index.

연구목적: 이동식크레인은 높은 사망률에 기여하는 기계로 최근 6년간(2016~2021) 사고사망사례 중 건설업 2,574건을 분석한 고위험요인(SIF)정보에서 이동식크레인의 사고는 총 61건의 재해가 발생하였다. 현장의 안전대책에도 불구하고 제대로 활용이 안되고 있다. 본 연구에서는 표준 리스크 평가 지수를 제시하여 사고예방에 기여하고자 한다. 연구방법: 전문가 면담과 사망사고 사례분석, 현장실태분석, 문헌조사를 통해 위험성평가의 4M방식의 표준 리스크 평가 지수 방법을 제시하고자 한다. 연구결과: 현장 8개현장 위험성평가를 분석한 결과 재해예방에 실질적인 기여를 할 수 없다는 결론을 얻었으며, 표준 리스크 평가 지수 방식의 개선방안으로 적용하여야 한다. 결론: 건설현장에서 표준 리스크 평가 지수방식으로 전환함으로써 안전보건관계자 및 근로자가 쉽게 이용할 수 있고 재해감소에 기여할 수 있을 것으로 제안한다.

Purpose: The purpose of the study was to develop a knowledge scale of risk factors for fall among community-dwelling older adults. Further, the validity and reliability of the scale was developed. Methods: A preliminary scale was developed through content validity by five experts and targeted subjects using the CVI (Content Validity Index). Following the establishment of content validity, the scale was used with 359 community-dwelling older adults to further establish both validity and reliability of the scale. Specifically, construct validity using known-group comparison technique, and reliability using Cronbach's ${\alpha}$ were established. Results: After content validity testing, 44 preliminary items were selected. Construct validity was established by known group-comparison, in which scores between the fall and no fall groups were compared. The Cronbach's ${\alpha}$ of the final scale was .83. Conclusion: Reliability and validity of the scale were confirmed. This tool may be used for measuring knowledge of fall risk factor for the community-dwelling older adults.
