The acute and subacute toxicity of New Woohwangchungsimwon(NWCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats(Sprague-Dawley, SPF) were injected intraperitoneally with dosages of 0, 540, 750, 1,070, 1,500 and 3,000 ㎎/㎏. Body weights were significantly decreased at 540 ㎎/㎏ dose group in both sexes and abnormal autopsy findings were founded in both sexes at all treated groups. Intraperitoneal LD_50 of NWCH was 812.3 ㎎/㎏ in male and 872.3 ㎎/㎏ in female rats. In the subacute toxicity study, NWCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800 and 2,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NWCH might be over 2,000 ㎎/㎏/day in this study.

Purpose & Method : To describe medical students' need on the mentoring program and relationship with career choice, 186/251 (74.1%) of first-and second-year medical students at Yonsei University College of Medicine. Seoul. Korea were surveyed. Result : 66.1% of medical students replied that he/she would volunteer as a mentee in mentoring program. Medical students' need area in mentoring program was specialty choice (62.9%). research development(18.8%), adapting to school life (13.9%) and effective learning skill (2.7%). 47.2% of medical students replied that his/her wishful career and working place is university faculty. Medical students who replied that he/she would volunteer as a mentee showed more needs on the research mentoring program(P=0.0112) and faculty career(P=0.0185) than those who replied that he/she would not volunteer as a mentee. Conclusion For successful implementation of mentoring program. this analysis on medical students' need should be considered.

The purpose of this study was to investigate the promotive effect of work-family conflict of married workers on proactive career behaviors, different from the previous research that has studied negative effects of the conflict on job attitude or behaviors. Also it tested moderation effects of performance evaluation justice and gender difference, provided that organizational efforts to ameliorate work-family conflict has actually not been working as much as expected due to workers' worry of unfavorable evaluation and the unbalanced gender role. The study conducted a survey research gathering data from 257 married workers, and analyzed the data using multiple regression analyses. The results showed that work-family conflict has a positive effect on proactive career behavior, and that performance evaluation justice has a moderation effect on the relationships between work-family conflict and proactive career behavior. However, gender did not show a significant moderation effect. Based on the results and limitations, the study provided implications for future research and practice.

As a result of the globalization of diseases and the delivery of health care, physicians today are required to understand global health (GH) including the global burden of disease, health inequities, and effective medical aid. Interest in GH among medical students has also increased significantly. To meet these needs and to reflect an increasing focus on social accountability in medical education, global health education (GHE) programs have already been well-established, particularly in North America. Korea's official developmental aid (ODA) volume almost tripled from 2006 to 2011. Korea has committed to double its ODA/gross national income ratio over the next three years. With these increases, interest in GH among medical students has significantly increased. Despite significant interest among medical students, GHE programs have not been properly established in Korea. To develop GHE programs in Korea, proposed GHE curriculum frameworks were reviewed and core values, guiding principles, and GH competencies were identified in the context of the current literature. To identify key themes essential to the development of GHE programs in Korea, the curriculum frameworks should be focused on a global context and should be taught from the perspective of the social, political, and economic causes of ill health.
지능검사에서 문항의 변경이 규준집단의 분포형태 및 표준점수산출에 미치는 영향: K-WAIS 바꿔쓰기와 K-WAIS-IV 기호쓰기를 중심으로
오승민,최승원 대한스트레스학회 2019 스트레스硏究 Vol.27 No.1
본 연구의 목적은 지능검사 개정시에 고려하지 않았던 변수가 표준점수의 설명력을 오염시킬 가능성을 알아보는 것이다. K-WAIS와 K-WAIS-Ⅳ의 직접적 비교를 위해 동일한 대상들에게 동일한 조건에서 서로 다른 조건의 기호쓰기를 실시했다. 그 결과, 두 검사에서의 검사지 간격과 보기 모양 등의 차이가 수행차이에 영향을 미쳤고, 난이도가 다를 가능성을 확인했다. 또한 K-WAIS의 바꿔쓰기와 K-WAIS-Ⅳ의 기호쓰기 원판에서 각 변수들을 K-WAIS의 바꿔쓰기 원판과 유사하게 변경 혹은 유지할수록 더 양호한 수행을 보이고, 부적으로 편포되었다. 이러한 수행 점수와 분포 특성은 표준점수를 산출하기 위한 완곡화 과정에 의해 동일한 기능의 개인도 각 검사에서 표준점수의 차이를 만들 수 있음을 의미한다. Background: The present study examined whether any unconsidered variable during revision of the K-WAIS would make standardized score of the test unreliable. Methods: In this study, a group of participants were assigned to perform modified ‘coding’ tests, respectively. To avoid the norm group issue, all the conditions except the stimuli were set as identical among the tests. Analysis focused which variable would affect difference among the tests, including their distribution patterns. Results: The results showed that physical differences of spatial organization across the tests and background such as figure shapes attributed to significant difference between 'digit symbol' in K-WAIS and 'coding' in K-WAIS-Ⅳ. Conclusions: It suggests that there exists possibility of different difficulty between 'digit symbol' in K-WAIS and 'coding' in K-WAIS-Ⅳ. Analysis of performance distribution also indicate that the test with better performance (K-WAIS coding) may have lower difficulty because its score distribution was more negatively skewed than the other.
다중경로 전기버스 시스템을 위한 충전 인프라, 버스 군 규모 및 관리, 배터리 용량 최적화

배터리식 전기버스(BEB)는 기존의 내연기관 버스를 대체하여 온실가스 배출량을 줄이는 차세대 친환경 대충 교통으로 주목받고 있다. 그러나, 도시 규모의 BEB 시스템을 계획하는 것은 복잡한 버스 네트워크에 제한된 배터리 용량과 충전 인프라 등 추가적인 제약 조건을 고려해야 하므로 매우 어렵다. 본 연구는 대규모 BEB 시스템의 복잡도를 낮출 수 있는 단일 충전소와 다중 경로로 이루어진 SC-MR 문제를 제시한다. 또한, 충전기 공유 및 버스 군 풀링 여부에 따른 다양한 시나리오에서 에이전시 총비용을 최소화하는 최적화 프레임워크와 세 가지 결정 인자(충전기 수, 버스 군 규모, 배터리 용량)를 결정하기 위한 대기열 이론 기반 솔루션 방법을 제안한다. 이를 검증하기 위해 4개의 경로로 이루어진 SC-MR 예제를 설계하고 시나리오별 결과를 비교 분석한다. 그 결과, 제시된 방법은 효율적으로 세 가지 결정 변수를 결정하고 시나리오별 운영비용을 최적화하였다. 또한, 충전기와 버스 군의 공유는 시스템의 충전기 수와 버스 수를 줄여 상당한 운영비용 절감을 보여주었다.
