Purpose: The study aims to identify the theme list and priority criteria of patient safety theme reports in South Korea. Methods: The survey was conducted twice, and the importance of each criterion and theme was measured on a nine-point scale using the Delphi technique by a panel of 19 patient safety experts. The criteria included severity, universality, preventability, and organizational-social impact. Descriptive statistics such as frequency, percentage, mean, standard deviation, median, and interval quartile range were used to analyze the data. Results: The parameters were assigned a weighted average of 35% for severity, 20% for universality, 30% for preventability, and 15% for organizational-social impact, respectively. The final top three rankings were surgery safety, blood transfusion safety, and medication safety. In addition to expert opinion, for the theme that is selected based on the priority ranking, one to five sub-topics can be derived from the theme based on the priority ranking, societal demands, or the yearly priority list of patient safety incidents. Conclusion: It is recommended that the official patient safety center distribute the report in the form of a summary that can be utilized nationwide at medical institutions, government institutions, and other places. Updates, as well as accumulated theme reports, will serve as the baseline data for the proposal of the system and for the policy designed to implement and improve institutions' safety practices as a standard of domestic patient safety practice guidelines.

This paper performed studies on a guide for an environmental assessment necessary to select railroad route optimally, and presented techniques for an environmental friendly route selection using AHP(Analytical Hierarchy Process) as an objective method. The AHP is an approach to decision making that involves multiple choice criteria into a hierarchy and assessing the relative importance of each criterion, and determining an overall ranking of the alternatives. For the purpose of this study, we established the weight and the order of major environmental assessment items based on the survey of experts. The results of the weight by AHP were in order of Fauna & Flora, Topography & Geology, Nature Environmental Assets, Noise & Vibration, Water Quality, Landscape and Air Quality indicating natural environment should be in priority. To develop the more efficient environmental friendly route selection systems, it is necessary to consider economical, technical, and social aspects in addition to environmental consideration.

Water quality improvement projects are being implemented without predicting the effect of water quality improvement on Lake Sapgyo. As the method of selecting the target stream for the effective conduct of water quality improvement projects the method of rating the streams were studied. To build a stream grading method, 60 major streams in the Lake Sapgyo system were monitored. The selection method of rivers subject to priority management for water quality improvement was applied to the stream grading method using the Analytic Hierarchy Process (AHP). The analysis of importance by site by stream grading method revealed the following: water quality (36.0%), flow (26.1%), travel load (13.4%), TMDL density (12.0%), TMDL (8.9%), and area (3.7%). The pollution level of the river was scored by using the stream grading method, and the ranking of 51 streams was calculated. Based on this, the group was classified into six grades (A-F). Among the groups, the F and E groups were selected as the priority management streams. Cheonan-Cheon (Cheonan City) was selected as the first stream to establish water quality improvement measures in the Lake Sapgyo system, and Seowoo-Cheon (Dangjin City) was selected as the second site, and Oncheon-Cheon (Asan City) was selected as the third site. Each local government is expected to improve the water quality improvement effect with limited resources when establishing and implementing water quality improvement measures for the streams (F group, E group) to be managed in this study.

This study is tried to identify the changes in modern Hanbok for the past five decades through the literatures and actual materials such as the First Ladies' costume. In Hanbok fashion, there is a trend that influenced by politics, economy and culture just like in western fashion. After liberation from the Japanese colonialism, the most important factors in Hanbok fashion were economic factors caused by the development of textile industry and the dressing attitude of the First Ladies at that time. In 1950s, a modified Hanbok that is easy to wear was popular. It was partly because of the west oriented atmosphere after the Korean War and mainly due to the practical dressing attitude of First Lady, Francesca. In 1960s and 70s, former First Lady Yuk Young Soo who loved and had good taste for Hanbok led the fashion. At that time, high ranking female social leaders as well as general public usually wore Hanbok on formal occasions. Therefore, textile industry for Hanbok developed a lot and tailored shops that specialize Hanbok emerged. In 1980s, as the economy got better, Hanbok was upgraded and it became more luxurious. Traditional Hanbok was revived through a historical investigation. Additionally, the former First Lady Lee Soon Ja helped fostering a luxurious mood as she wore a Hanbok as a formal dress. After 1988 Olympic Games were successfully held, the importance of the traditional culture was emphasized in 1990s and Hanbok followed retro trend rigorously through the academic approaches including a dressing history. Hand painted and naturally dyed Hanboks were strong in this period. Former First Lady Kim Ok Sook's sophisticated Hanbok attire partially had effect on this mood. However, From the late 1990s Hanbok became less popular. It was partly because the former First Lady Son Myoung Sun and Lee Hee Ho preferred western style dresses and did not play a role as Hanbok fashion leaders.
