A CBR(Case-Based Reasoning) system solves the new problems by adapting the solutions that were used to solve the old problems. Past cases are retained in the case base, each in a specific form that is determined by features. Features are selected for the purpose of representing the case in the best way. Similar cases are retrieved by comparing the feature values and calculating the similarity scores. Therefore, the performance of CBR depends on the selected feature subsets. In this research, we measured the Selection Effect and the Elimination Effect of each feature. The Selection Effect is measured by performing the CBR with only one feature, and the Elimination Effect is measured by performing the CBR without only one feature. Based on these measurements, the feature subsets are selected. The resulting CBR showed better performance in terms of accuracy and efficiency than the CBR with all features.

The outcome of study has shown that team approach in case management in the community welfare center has shown a fair amount of effectiveness in increasing the quality of life for the elderly. 30 elderly people who had complex difficulties in life were selected and given case management for a 6 month period. The student volunteers supervised by a case manager visited the clients once a week and arranged a series of community resources following assessment of the clients' needs. A group of professionals active in the community was invited for supervision. Compared to the clients in the comparison group, those clients who case management showed the increase in the quality of life and life satisfaction scale. The results of the study suggest that face-to-face service for the elderly is one important factor for successful case management intervention. Also, a team approach in case management utilizing professionals and volunteers can be useful for the case manager in the community welfare center who is overwhelmed with too many case loads.

The purpose of this study was to confirm the effect by case management and durability of the effect, which targeted on the 115(51 men and 64 women) people who had undergone diabetes case management through the National Health Insurance Corporation from May 1. 2007 to June 30. 2007. In order to evaluate the effect of case management and durability, the study was examined just before the case management, right after case management, after 6 months and after 12 months through classifying case management 1(Group I) and case management 2(Group II). As a result, the participants' blood glucose level in the diabetes case management improved just after the case management compare to just before one. but it had a tendency to increase once more after 6 months and 12 months case management. In addition, it was confirmed to maintain the effect by the case management in Group II compare to Group I.

This study conducted a meta-analysis on the variables related with case management performance in Korea. In order to do a meta-analysis, a total of 27 journals, theses and dissertations published between 1998 and 2020 were reviewed systematically. Through this process, this study calculated average effect size of each variable and explored moderator variables. This study results were as follows. First, this study identified a total of 14 individual, enviroment of institution, population variables related with case management performance. Second, the results indicated that case management performance variables which showed large effect sizes included professional capability, supervision, network, case management significance recognition, manual, agency support. Third, variables with medium effect sizes included self-efficacy, case management education, autonomy, motivation, number of conference and variables with small effect sizes included work experience, academic ability, age. Fourth, Moderator effects were identified in the field, target, publication of case management. Finally, the implications of the study findings were discussed.

인쇄를 통해 다양한 특수효과를 표현하는 것은 해당 업체의 작업 범위를 확대할 뿐만 아니라 경쟁력 강화에 큰 도움이 된다. 새로운 수요층을 발굴하는 것은 물론이고, 다른 분야에 종사하는 업체들로부터 외주작업도 수주할 수 있기 때문이다. 실제로 미국에서는 디지털 인쇄기나 후가공 장비를 통해 다양한 특수효과를 실현함으로써 시장 확대와 경쟁력 강화에 성공하는 사례가 늘고 있다.

The purpose of this study was to confirm the effect by case management program and durability of the effect, which targeted on the 250(101 men and 149 women) people who had undergone hypertensive patients case management program through the National Health Insurance Corporation from May 1. 2007 to June 30. 2007. In order to evaluate the effect of case management and durability, the study was examined just before the case management, right after case management, after 6 months and after 12 months through classifying case management 1(Group I) and case management 2(Group II). As a result, the participants' blood pressure level in the hypertensive patients case management improved just after the case management compare to just before one. but it had a tendency to increase once more after 6 months and 12 months case management. In addition, it was confirmed to maintain the effect by the case management in Group II compare to Group I.

Recently graphic hardwares have been developed remarkably, and domestic and foreign game users have demanded realistic and spectacular game graphics. Graphic special effects are one of methods to satisfy these requests, but we have not known any cases where graphic special effects are general and thus reusable. Based on the implementation of our graphic special effect engine and its application cases, this paper describes how to easily exploit graphic special effects in developing games. We define a standard file format in which special effect data can be saved and loaded, and thus those data can be reused easily. We also show that developers can test or preview special effects by exploiting our graphic special effect tool even before producing games.
