Purpose: The aim of this study is to evaluate the medical students consciousness on volunteer activities. What kinds of volunteer activities they had done, what kinds of volunteer activities they want to participate in, how they think about making volunteer program as school regular curriculum, and how they feel about volunteer activity. Materials and Methods: Study subjects are first, second grade premedical students and first, second grade medical students. Self-administered questionnaire was conducted at October, 1999. Finally, 119 questionnaire is collected, which is 74% of all students except 3rd, 4th grade students. Results: Study subjects had participated in several volunteer activities. 44.5% of them had participated in some volunteer activities since they had become to college student, 30.8% of them participated in summer rural volunteer activity, and 39.3% of them had donated their blood. Many students (79.66%) agreed that volunteer activities are required as college students, and if they might have some opportunities to participate in volunteer activities, they would like to (54.17%). However, Only 22.50% of subjects agreed to make volunteer activities as regular medical curriculum. Even though the percentage showed low, they intended to apply to the curriculum (40.83%). Most of them agreed there were in need of participating in hospital volunteer activities (82.50%) and community volunteer activities (78.33%). Among hospital volunteer activities, they wanted to participate in volunteer activities at supporting department (26.05%), emergency room (22.69%), out-patient department (21.01%), and in-patient department (21.01%). They wanted to have volunteer activities at institution (66.39%) rather than to individual person (33.61%). They wanted to participate in friendly supports (40.34%), out-going supports (28.57%), house work supports (22.69%). Factor analysis showed that recognition of volunteer activities had 5 latent dimensions: ‘self-achievement (16.15%), ‘social exchange and the pursue of experience (13.93%) , ‘social responsibility of college (13.03%) , ‘leisure of worth and expert activity (12.40%)’, ‘passive and meeting other s expectation (9.03%) Conclusion: From above results, We found premedical and medical students had participated in various volunteer activities and they had much more intention to participate in. Before developing and designing volunteer programmes, One should consider they have various aspects on the programmes. The programmes should not be emphasized on altruistic aspect and social responsibility extremely, but rather it should be considered how the programmes could give the opportunities for the social exchange, social relationship, sense of solidarity, and usefulness of acquired medical knowledge and skill.

조선소 강재적치장에 입고된 선반용 후판은 오버헤드 크레인을 이용한 반복적인 선별 작업을 통해 강재 절단 일정에 따라 재적치된 후 가공 공장으로 출고된다. 본 연구에서는 병렬적으로 선별 작업을 수행하는 두 대의 오버헤드 크레인을 대상으로 makespan 최소화를 위한 크레인 스케줄링 알고리즘을 제안한다. 제안된 알고리즘은 강화학습 기반의 동적 스케줄링 방법론을 적용하여 출고 시점이 불확실성을 고려한 실시간 의사결정을 지원한다. 제안된 알고리즘은 휴리스틱과의 성능 비교를 통해 크레인 간 간섭을 고려한 보다 효율적인 스케줄링이 가능함을 확인하였다.

Unruptured dural arteriovenous fistula (dAVF) manifests various symptoms including exophthalmos, headache, tinnitus, and retro-orbital pain. Transient global amnesia (TGA) is a clinical syndrome of reversible anterograde amnesia. Here, we report a 62-year-old woman with dAVF, manifested as TGA. This case emphasized that the clinicians should stay vigilance to the organic cause of TGA, especially in those complaining other symptoms besides amnesia such as pulsatile tinnitus and headache. Furthermore, our case supports a hypothetical patho-mechanism of venous congestion for TGA.
