The main purpose of collecting and analyzing operating experience events is to look for insights to improve safety. The underlying assumption is the correlation and causality between events with different safety significances. The analysis of this assumption could be valuable to optimize operating experience feedback programs and to enhance safety. This paper analyses the correlation between events with different safety significances. Groups of events from six nuclear energy related databases are considered. The findings are that a correlation exists but with various levels and not as large or consistent as might be expected across different databases. These results might be the basis for further work to analysis causality, to find out how a similarity in causes influences the correlation, and finally to improve the operating experience program.

The purpose of this study was to analyze the types of lesson and its effectiveness with digital textbook. To address those goals, we had observed five classes of the primary school, which designated as a research pilot school for digital textbook. Based on the result of observation, 3 types of lesson with digital textbook were categorized: Teacher-directed lecture (type 1), Blended learning (type 2), and Flipped learning (type 3). Depending on the type of lesson was analyzed the positive and negative effectiveness by means of matrix analysis method. As a result, in Teacher-directed lecture (type 1), there was found out the participation of the lesson in atmosphere of stable and comfortable as positive experience, also digital textbook operating immature and boring as negative experience. In Blended learning (type 2), there was found out the fun by sharing the product and peer feedback, and flow by learning transfer as positive experience, also digital textbook operating immature and understanding the difference between assignments as negative experience. In Flipped learning (type 3), there was shown the positive attitude and ownership in the lesson as positive experience, also distracting and boring in the lesson when learner was excluded in participation as negative experience. Based on the results, we suggested some strategies for improving positive experience and protecting negative experience in the lesson with using digital textbook.

현재 피트니스 트래커(fitness tracker)시장은 유산소 운동에만 초점을 맞춰 근력 운동 분야는 상대적으로 소외되어 있다. 최근 근력 운동 피트니스 트래커가 소수 출시되고 있으나, 운동 상황에 대한 고려가 부족하여 사람-기기 간 인터랙션에 불편함을 초래한다. 특히, 운동 중에는 신체의 움직임이 활발하므로, 손으로 기기를 휴대하거나 기기를 조작하는 상황은 사용자에게 부정적 경험을 유발한다. 웨어러블 디바이스는 항시적인 착용이 가능하므로, 손과 발의 사용이 자유로워 운동 중 피드백 제공에 효과적이다. 따라서, 이 연구에서는 웨어러블 디바이스를 통해 피드백을 감각하게 함으로써, 운동 수행자가 효과적인 운동을 할 수 있도록 하는 것을 목적으로 한다. 이 연구에서는 다음 세 가지 연구 문제를 검증하였다. 1) 운동 상황에서 필요한 정보는 무엇인가? 2) 근력 운동 중, 어떤 감각 피드백이 선호되는가? 3) 근력 운동 중, 감각 피드백의 가치는 무엇인가? 그 결과, 첫째, 운동 수행자는 운동 단계 중, '운동 중'에 해당하는 정보가 가장 필요하다고 하였으며 '페이스 조절(횟수 카운팅, 동기 부여)'과 '자세 지도(문제점 진단, 자세 교정)'에 해당하는 정보를 가장 필요로 하였다. 둘째, 운동 중 선호되는 감각 피드백에 대해서는 청각 피드백, 촉각 피드백, 시각 피드백 순으로 만족도가 높았으며, 운동 강도가 높을수록 감각 피드백에 대한 만족도가 더 높았다. 셋째, 감각 피드백과 기기 피드백의 가치에 대해 비교한 결과, 기기 피드백과 사람이 제공하는 피드백에 대한 만족도, 유용성, 효용성이 비슷하게 나타났다. 결론적으로, 이 연구에서는 근력 운동 중, 웨어러블 디바이스를 활용한 감각 피드백의 디자인 가이드라인을 도출하였으며, 웨어러블 디바이스의 감각 피드백이 사람이 제공하는 피드백을 대체할 수 있다는 가능성을 확인하였다.

Background: With the increasing use of narcotic analgesics, the Ministry of Food and Drug Safety has been operating the National Narcotics Information Management System (NIMS) since 2018 in Korea. Some studies are related to the narcotic analgesics use, but the evaluation studies of system, including NIMS users are insufficient. Objective: This study evaluated the NIMS enforcement process through in-depth interviews on the experience of using NIMS of doctors and pharmacists who prescribe or dispense opioid analgesics. Methods: Participants in this study were selected through purposeful sampling as three doctors and two pharmacists in the metropolitan area. The interviews were conducted from August 27 to October 19, 2022. Each interview was analyzed using a phenomenological method. Results: Six components of this study included "Doctors and pharmacists come across drug abusers", "They respond individually to drug abusers", "They use NIMS tailored to the needs of system managers", "They are concerned about the role of NIMS in practice settings", "They face challenges against drug abusers" and "They find a way to utilize the system to deal with drug abusers." The interviews confirmed that doctors and pharmacists used NIMS little in their work, and they only reported data. Therefore, it might be difficult for doctors and pharmacists to take measures for the safe use of narcotic analgesics. Conclusion: It is likely that adding data-feedback and medication-check function can reduce the abuse of narcotic analgesics. In the future, further studies on the evaluation of the empirical results of NIMS and review of systems in other countries will be required.
