이상화 한국보건의료인국가시험원 2021 보건의료교육평가 Vol.18 No.-
Purpose: Setting standards is critical in health professions. However, appropriate standard setting methods do not always apply to theset cut score in performance assessment. The aim of this study was to compare the cut score when the standard setting is changed fromthe norm-referenced method to the borderline group method (BGM) and borderline regression method (BRM) in an objective structured clinical examination (OSCE) in medical school. Methods: This was an explorative study to model the implementation of the BGM and BRM. A total of 107 fourth-year medical students attended the OSCE at 7 stations for encountering standardized patients (SPs) and at 1 station for performing skills on a manikinon July 15th, 2021. Thirty-two physician examiners evaluated the performance by completing a checklist and global rating scales. Results: The cut score of the norm-referenced method was lower than that of the BGM (P<0.01) and BRM (P<0.02). There was nosignificant difference in the cut score between the BGM and BRM (P=0.40). The station with the highest standard deviation and thehighest proportion of the borderline group showed the largest cut score difference in standard setting methods. Conclusion: Prefixed cut scores by the norm-referenced method without considering station contents or examinee performance canvary due to station difficulty and content, affecting the appropriateness of standard setting decisions. If there is an adequate consensuson the criteria for the borderline group, standard setting with the BRM could be applied as a practical and defensible method to determine the cut score for OSCE.

In Korea, although the damage from disaster (flood and storm) is increasing, the early stage warning and countermeasure are not in operation rapidly. The research areas of transportation engineering arenot diverse, so once the road is flooded and interrupted, drivers, the system operators and managers are in panic, and nearby roads are in terrible traffic congestion. In case of Korea, the research of evacuation is highly needed, because it is very necessary and easy to apply in real field. In this paper, we establish the concept of transportation disaster prevention system and suggest the directions of it. In addition, based on this research, we choose one example of disasters and establish an example of the transportation disaster prevention system. Our goal is to make steps; prevention, preparation, countermeasure and restoration in the view of minimizing on social chaos and damages emphasizing aspect of transportation countermeasure. This research will be the good precedent of approach, analysis and countermeasure when the disasters are occurred, and a basis of transportation disaster prevention system and manual in Korea.
