  • This paper describes a new quantitative process for evaluating the roughness of discontinuity, which is suggested as a qualitative criteria in RMR or Q-system. For this purpose, the Delphi method which is one of the surveying methods was introduced. The selected panels were asked to evaluate the roughness of discontinuities on the Web which was hosted by authors in advance. A total of 3 surveys were performed using JRCs suggested by Barton and Choubey as well as Ai generated by the Monte Carlo simulations. After each survey, the results were provided to all panels for comparing their decisions to others. As surveys proceeded, better consensus and convergence were achieved. With a good agreement of panels on roughness classification, the quantitative criteria for roughness of discontinuity in RMR and Q-system was established in this study.

  • In this study, I worked on necessary contents for Information Literacy of Korean universities by Delphi Method. The survey resulted in 100 necessary contents in five categories and each category presents average points and ranks of importance. Contents of high rank in each category should be valued highly when educational programs are to be designed. One remarkable difference in comparison with ACRL standards is that there are a lot of contents involved with basic understanding about Scientific Information System and Information Technology and knowledge application in this study, and another is that there is a lack of contents which require analytic judgements. The significance of this study lies in presenting directions and discussion points in designing of Information Literacy of Korean universities.

  • Objectives: The objective of this study was to develop evidence- and consensus-based clinical safety usage guidelines for sedative hypnotics using the Delphi technique. Methods: A group of 15 sleep experts from Korean Academy of Sleep Medicine were chosen for this study comprising a three-round web-based Delphi survey. The first round survey was composed of 39 questions to identify problems with sedative hypnotics usage in Korean clinical practice and the result roughly outlined what should be included in the guidelines. The second round survey was composed of 21 questions to collect specific opinions of experts on clinically important issues in prescribing sedative hypnotics, and its result provided the basis for the guidelines. A third round survey aimed to evaluate the reliability and validity of the established guidelines. Results: In the third round, all 17 items showed a median of 4 or more, with an average of 4.12 and a standard deviation of 0.32. Thus we present safety usage guidelines with 13 propositions for prescription, maintenance, and withdrawal of sedative hypnotics. Conclusion: The safety usage guidelines on sedative hypnotics developed from this study could lead to safe and effective prescription of hypnotics in clinical practice, especially for the non-experts in sleep medicine. Furthermore, the guidelines will help to improve the quality of insomnia treatment by contributing to the establishment of a safe regime for sedative hypnotics without excessive use of drugs.

  • 유역의 홍수위험도를 평가하기 위하여 선행 연구로서 DPSIR framework를 적용한 인자를 선정하였다. 이때 인자의 범위를 사회적, 경제적, 환경적 분야로 구분하고 각 분야에 대하여 홍수로 인하여 야기되는 유역의 다양한 영향요소를 포함하여 인자를 선정하였다. 본 연구에서는 이를 대상으로 각 인자의 가중치를 선정하기 위하여 패널식 조사연구기법인 Delphi 방법을 적용하였다. Delphi 기법은 델파이 절차가 반복되는 동안 조사 참여자에게 전회의 조사 결과, 즉 통계적 집단 반응을 피드백하며 참여자는 이를 참고하여 자신의 판단을 수정 보완 할 수 있는 방법이다. 따라서 1차 설문조사를 통하여 각 패널은 홍수위험도 평가 인자에 대해서 주관적인 가중치를 선정하고 이를 분석한 결과를 피드백 받아 참고한 후 2차 설문조사에 응하여 가중치를 재선정하게 된다. 조사에 참여할 패널의 선정은 수자원분야의 전문가를 대상으로 하였다. 또한 각 인자에 대한 가중치를 수집하는 방법을 다양하게 설정하여 기법에 따른 영향을 검토하였다. 수집기법은 상대적 가중치 결정법 중에서 가장 많이 사용되는 순위법과 직접입력법, 절대적인 기준에 대한 가중치를 수집하기 위하여 Fuzzy 가중치 입력법을 사용하였으며 이 때 각 인자가 소속되는 분야와 DPSIR framework 요소에 대해서도 별도로 가중치를 수집하여 최종적인 인자의 가중치를 결정하였다. 본 연구는 추가 연구를 통해 남한강에 적용되며 인자의 자료는 문헌조사, 통계자료 조사 및 수리학적 수치모형 등의 분석을 통해 수집될 예정이다. 이를 통하여 사회, 경제, 문화, 환경적인 측면을 고려한 인자들을 반영한 하천의 구간별 상대적 홍수취약도를 정량적으로 제시할 수 있으며 하천 구간별 치수관리 우선순위를 결정하는데 적극적으로 활용될 수 있다.

  • Purpose: In this study, the Drenzer facility, which is a facility installed to prevent the spread of fire caused by fire in adjacent buildings in the fire prevention zone, was analyzed legally and technically. We confirmed the uncertainty of the Building Act and the Fire Protection Act, and suggested the revision of the necessary standards. Method: Although the Drenzer facility is a building facility, it is actually applied in the field of firefighting, so the Delphi analysis was conducted on a panel composed of architectural experts and firefighting experts in the first, second, and third rounds to find the issuses and important facility component elements. Finally, the IPA(Importance-Performance Analysis) analysis was conducted to identify the importance of the elements that need to be revised. Result: Delphi analysis was carried out for experts on various components of Drenzer equipment in the first, second, and third rounds, and it was found that the survey items of the head, detector, and other facilities of the Drenzer equipment are valid items to identify problems. The IPA analysis indicated that the revision of the standards for Drencher head was necessary as a priority. Conclusion: In this study, it was possible to confirm the opinions of experts through Delphi analysis on the legal and technical problems of Drencher facilities, and it was confirmed that among the components of the Drencher facility, the revision of the head-related regulations is required as a priority.
