The objective of this study is to investigate the safety awareness and effectiveness of the education and training for employees engaged in radiological emergency organization of the Korea Atomic Energy Research Institute (KAERI). In 2022, the questionnaire for the education satisfaction survey was revised to regulary evaluate the effect of edcation on perceptions of importance on emergency preparedness for nuclear research facilities. In line with, a standard questionnaire was created which covers 3 factors and 9 attributes, and the evaluation indicatior is based on a 5-point Likert scale. In 2023, the education on radiological emergency preparedness was conducted for 235 emergency staff. From May 24 to July 13, 2023, data was collected from a total of 235 emergency response personnels, including 28 new staffs and 207 maintenance staffs. Aa a result of response analysis, it was identified that education for radiological emergency response had a significant correlation with the promoting safety culture. It was found that senior emergency personnel with more years of experience are highly interested in radioactive disaster prevention and actively participate in and training. On the other hand, it was presented that new and less experienced groups tend to have a relatively high scored of the risk perception of nuclear research facilitites. Therefore, it is necessary to improve the practical curriculum in order to increase the participation of junior disaster prevention personnel in education and training, ensuring that they correctly recognize the risk of research facilities. This results are expected to be used to improve the quality of education and drills for radiological emergency response at KAERI.

Since cranes are a kind of complex human-machine systems, it is almost impossible to completely secure safety with current technologies. Therefore, managerial interventions to prevent human errors are needed for safely operating a crane. The Occupational Safety and Health law states that cabin-type crane operators should have crane drivers’ licence and crane-related operators (e.g., pendent-type crane operators, slinging workers) should take a special safety training. However, statistics on industrial accidents showed that fatalities due to crane accidents (185 accidents occurred during 2013~2017) were the highest among hazardous machinery and equipment. To effectively control the crane-related accidents, voices of crane workers need to be analyzed to investigate the current status. This study surveyed perceived causes of crane accidents and status of special safety training for crane workers of 387. The survey revealed that 24.3% of the respondents experienced crane accidents and 31.4% eye-witnessed crane accidents. 79% of the respondents pointed human errors such as improper crane operation and improper slinging as the first cause. Lastly, only 16.7% of the respondents took a professional special safety training; but the rest took lecture-based or incomplete education. The findings of the present study can be applied to improve crane-related policies and special safety training systems.

Purpose: This study attempted to enhance the nurses’ safety competence in administering medications by using simulation training focused on high-alert medication. Method: A total of 30 nurses from 14 teams participated in the simulation training using a high-fidelity patient simulator. Medication administration performance and built-in error recovery was observed using a medication administration safety assessment checklist. Medication safety knowledge and confidence were measured before and after simulation training. Data were analyzed using descriptive statistics and a paired t-test. Results: There were numerous variations in safe medication administration. The safety behavior by oral prescription was insufficient compared to that by routine medication prescription. Following simulation training, knowledge of medication safety increased significantly, but confidence did not. Conclusion: Nurse educators may consider simulation to be an effective strategy for enhancing nurses’ medication safety competence.

A forklift accident occurs in the logisitcs center. there are many kinds of accidents such as a casualty accident or a minor accident, etc. there are many other causes of accident, including poor　visibility and habitual operational mistakes The result of the accident is the phenomenon of cutting, falling,　scratching of the product. In the case of minor accidents, workers do not report accidents, so the occurrence of accidents is unknown. The customer receives the goods and then notifies them that they are defective product. After the product is returned, we can see that the forklift accident caused the problem of the product The result of the late response affects the image of the enterprise. In this study, we recognized the need for safety education to prevent accidents and found out which of the education items could raise awareness of safety. As result of the study, disinfection and forklift maneuverability regarding speed were mentioned as the most important items in education.

본 연구는 선박에서 발생할 수 있는 화재연기의 위험성을 인식시키고 비상대응능력을 향상시키기 위해 선내에 안전교육을 위 한 환경을 구축하고 시나리오를 개발 운영하면서 획득한 실습생의 상황별 이동특성을 측정분석한 것으로, 그 결과를 정리하면 다음과 같다. 연기가 없는 조건에서는 익숙한 이동경로에 장애가 발생한 경우와 그렇지 않은 경우의 각 피난이동 상대속도 사이에 차이가 없지만, 실내에 연기가 충진되어 가시도가 매우 낮은 조건에서는 시야불량에 따른 이동능력 저하로 인해 그렇지 않은 경우에 비해 평균상당속도 가 62.5% 감속되었다. 시나리오에 관계없이 단순이동경로에 비해 복잡이동경로의 평균 상당속도가 빠르고 표준편차도 작게 나타났다. 연기가 충진된 경우에 대한 단순 데이터 평가에서는 전체이동경로와 복잡이동경로의 상대속도 확률분포가 매우 유사하였지만, 전체이동경 로의 상대속도에 대한 복잡이동경로의 상대속도비율의 개인간 변동폭은 매우 컸다. 한편, 상당속도는 가시거리의 로그함수로 표현할 수 있었다. 또한 실습생의 긴장감이 증가하면서 모든 경로에서 상대속도가 빨라졌다.
