In order to expand the qualitative aspects of public facility, this study used SNS data to derive user-oriented preference factors for public facilities and then were quantified in terms of supply side and demand side. To derive preference factor, LDA, one of topic modeling, was used and attraction index was calculated for each facility. In addition we analyzed spatial accessibility to measure the degree of service experience of users by using 2SFCA model. The study area covered public libraries of Seoul, Korea. As a result of study, five topics were extracted as preference factors for the public library: Circumstance, Scale of facility, Cultural program, Parenting, Books and materials. In particular topic of circumstance and parenting were newly derived preference factors unknown in previous studies. As a result of calculating attraction index for each library, the index of Songpa Library, Jungdok Library, and Namsan Library was high. Songpa library has received good evaluation in parenting factor, and Jungdok & Namsan library in circumstance factor. The accessibility of each region seems to better in center of Seoul where public libraries are crowded, but shrinking toward the outskirts. We expect that the proposed method will contribute to user-oriented public facility evaluation and policy decision making.

Web환경의 발달로 인해 아바타(Avatar), 사이버캐릭터(Cyber Character), 사이버 펫(Cyber Pet), 이모티콘(Emoticon)등의 멀티미디어 캐릭터들이 등장하게 되었다. 인터넷 사용자들이 과거에는 Web의 익명성에 매료되었다면, 현재에는 이러한 멀티미디어 캐릭터를 이용하여 자신을 표현하고 나타내고자하는 욕구들이 늘어나고 있다. 따라서 본 연구에서는 다양한 멀티미디어 캐릭터 중에 아바타 캐릭터 Type에 대한 사용자들의 선호도와 선호요인을 조사하여 일반 캐릭터와 상호비교 해봄으로써 기존의 일반 캐릭터와는 다른 아바타 캐릭터만의 특성에 대해 알아보고 아바타 캐릭터 제작시 가장 효율적인 접근방법을 제시하고자 하였다. 그 결과 가장 효과적인 아바타 캐릭터 Type은 캐릭터의 형태나 성격, 느낌을 우선적으로 고려하기보다는 먼저 아바타 캐릭터의 기능적인 면을 고려한, 즉 사용자의 개성이 좀더 어필(Appeal)될 수 있어야 하며 사용자의 개성연출에 적합한 Type으로 제작되어야한다는 결론을 내릴 수 있었다.

Analyzing mode choice among transportation demand estimate procedures is complicated and understanding characteristics of travelers is also difficult. Generally, it is well known that traveler choose mode considering psychometric factors and characteristic besides socio-demographic indicators. Accordingly, many researches has investigated on methodology that can be applied in mode choice to reflect psychometric factor or specific preference. Latent Class Analysis among various studies is recognized as the theoretically potential approach. This study focuses on class segmented using latent class cluster to analyze impact that included psychometric factors and characteristics on mode choice. It also provides evidence that mode choice model for each class and mode choice model not considering latent class are different. This study based on citizen's stated preference and revealed preference on a new transit on the Han river shows that latent class cluster analysis is the potential approach considering latent preference.

We analyzed the characteristics of the physicians preferred information sources and barriers through in-depth interviews. Information searches for patient treatment were subdivided into deciding patient treatment methods, understanding the latest treatment trends, and preparing presentation materials for conferences. The variables that affected the search behaviors were identified as being background knowledge on the topic, clinical experience, job title, search skills, user training, and familiarity with the library homepage. PubMed was the most preferred choice because of users' familiarity, reliability, and the vastness of information; Google was also used frequently for easy access and fast search result. The accuracy and the recentness of information were the most significant criteria. Easy interface and convenient access were also considered important due to physicians' time constraints. Searching obstacles were divided into difficulty of searching system, unfamiliar term, too vast resources, difficulty to get fulltext articles and complex advanced search features. The results of this study can be utilized as a basis for improving information service of library and curriculum development for physicians.

The present research investigated and compared stress coping strategies of North Korean refugees with those of South Koreans in the purpose to predict and prepare psychological conflicts expected to occur during the Korean reunification. Adapted from Han, Hur, Chae, and Kim(2001), North Korean refugees recorded their coping strategies that they would employ in stressful situations varying in term of three aspects of stress causes - 2(locus: internal/external) × 2(stability: temporal/enduring) × 2(context: individual/interpersonal) - and the responses were classified in terms of three dimensions(active/passive, approach/avoidance, cognitive/affective/behavioral). In the temporal stress situations, adaptive North Korean refugees preferred active over passive, approaching over avoiding, and behavioral over cognitive/affective stress coping strategies more than maladaptive North Korean refugees did. Also, in the stressful situations caused by external causes, they were more likely to take active rather than passive, approaching rather than avoiding copying. Although active copying strategies were preferred to passive ones by adaptive North Korean refugees in individual stressful situations, approaching copying strategies were preferred to avoiding ones by them in interpersonal stressful situations. These findings were found to be different from the pattern of South Korean's stress coping strategies in the same situations. In conclusion, the differences were discussed in the view of psychological integration during Korean reunification.
