To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.

1. 95년,96년 자율평가고사는 형성적 평가의 도구로서 타당성이 있었다. 2. 2년간 자율평가고사에서 지속적으로 하위권에 머무른 사람은 1차 전문의 자격고사에서도 하위권에 머무는 경향을 보였다. 따라서 지속적으로 하위권에 속한 사람들을 확인 할 수 있는 개인별 향상 지수는 형성적 평가척도로서 타당성이 있었다. 3. 1차와 2차 저눈의 자격고사의 성적은 서로 높은 상관관계를 보여 두 시험간에 유의한 분별도가 있었다. 그러나 총괄적 평가도구로써는 1차 전문의 자격고사가 보다 더 타당성이 있었다. The korean society of otolaryngology has had and experience on intraining examination since 1992. We also had the fortieth annual board examination for specialist in 1997. But we have no evidence on the validity of these tests yet. The aim of this study is to examine the validity of the intraining examinations as a tool of formative evaluation, to present a personal progress index demonstrating constructive validity, and to examine the validity of the board examination as a tool of summative evaluation. We did statistic analysis on the consecutive personal scores of 1995 and 1996 intraining examinations, and 1997 written and oral board examinations. Analysis of the averages, standard deviations, distribution curves, and Wilcoxon singed rank test on the scores of 1995 and 1996 intraining examinations demonstrated the constructive validity. Chi-square test revealed that those who had low scores in intraining examinations of two consecutive years had low scores in 1997 board examinations and personal progress index demonstrated the predictive validity. Correlation and linear regression analysis demonstrated a strong correlation between 1997 written and oral board examination. Analysis of the averages, standard deviations, distribution curves, and Spearman rank correlation coefficient revealed that 1997 written board examination had higher concurrent validity than the that of oral examination.

현재까지 한국불교전적 및 한국 고문헌에 대한 전산화는 매우 미미한 실정이며, 웹에서의 한국불교전적을 포함한 한국 고문헌에 대한 검색 시스템은 전례를 찾아보기 힘들다. 그러나 문화유산의 전산화 및 전자도서관화는 세계적인 추세이며, 고문헌의 전산화 및 웹에서의 검색 서비스 제공은 해당 분야의 연구자들에게는 시급히 필요한 과제이다. 또한 본교는 불교학을 중심으로 한 한국학과 컴퓨터 정보통신 두 분야를 특성화의 큰 축으로 하고 있으며, 불교자료의 전산화야말로 본교의 특성화 방향인 "불교학과 정보통신 기술"의 연계에 가장 적합한 프로그램이라 할 수 있다. 따라서 본 연구의 목적은 우리의 문화유산인 한국불교전서 중의 9책과 10책을 컴퓨터에 입력하여 데이터베이스에 저장하고, 이를 효율적으로 검색할 수 있는 검색엔진을 개발하여, 현재 전 세계적으로 범용화 되고 있는 인터넷의 웹을 통해 검색할 수 있도록 하는 것이다. 이렇게 본 연구를 수행함으로써 고문헌의 전산화를 활성화할 수 있으며, 전자도서관을 이용한 문화유산의 관리를 촉진할 수 있을 뿐만 아니라, 우리나라 문화유산에 대한 종합적인 전산화 기술을 개발할 수 있다. It is not enough effort to digitizing the Korean Bulgyo Chonso or the Korean archaic documents until now. Also, it is difficult that we look up systems which retrieve the Korea archive documents in the Web. However, digitizing of culture heritage is a worldwide trend. So, digitizing of the archive documents and using retrieval systems in web are subject which must solve urgently. We are regarding koreanology that focus on the buddhism philosophy as a main study for a university specialization with the computer information communication. Digitization of buddhism data is most suitable to the nexus between the buddhism philosophy and the information communication technique. So, purpose of this research is to store the 9th and 10th volume of Hanguk Bulgyo Chonso in database, to develop a retrieval engine for efficiently search this database and to supply a retrieval service through the Web. The retrieval system can induce to activate digitization of the archive documents, to promote management of the culture heritage using digital library, and to develop synthetic of digitizing technique for the culture heritage.

Comparison of Endoscopic Endonasal Reduction and Transcaruncular Reduction for the Treatment of Medial Orbital Wall Fractures

Han, Kihwan,Choi, Jae Hoon,Choi, Tae Hyun,Jeon, Sea Yuong,Kim, Jun Sik,Kim, Nam Gyun,Lee, Kyung Suk,Son, Daegu,Kim, Jun Hyung,Kim, Sang-Hyon,Kang, Dawon,Park, Jungbin Lippincott Williams Wilkins, Inc. 2009 Annals of plastic surgery Vol.62 No.3

Currently, endoscopic endonasal reduction and transcaruncular reduction are frequently used as surgical treatments for medial orbital wall fractures. However, these 2 surgical techniques have not been comprehensively compared using objective criteria. Therefore, the results of these 2 techniques were compared retrospectively using 8 objective criteria in patients with medial orbital wall fracture.This study included 48 medial orbital wall fracture patients treated from June 1993 to July 2006: 29 had endoscopic endonasal reduction and 19 had transcaruncular reduction. Computed tomographic scans, double vision field testing for diplopia using Goldmann perimetry, and Hertel exophthalmometer (Richmond Products, Albuquerque, NM) were done pre- and postsurgery.The average follow-up period was 70.8 months. Among patients with pure medial orbital wall fractures, the average reduction rate was 89.2% for the endoscopic endonasal reduction group and 90.7% for the transcaruncular reduction group. One case in the endoscopic endonasal reduction group had a more than 2-mm enophthalmos after surgery. The diplopia correction rate was 1.8% in the endoscopic endonasal reduction group and 2.7% in the transcaruncular reduction group. None of the above differences was statistically significant. However, among patients with pure medial orbital wall fractures compared with the transcaruncular reduction group, the average operation time, the average hospital stay, and the average cost were significantly greater in the endoscopic endonasal reduction group.The 2 surgical methods had a similar effectiveness; however, transcaruncular reduction seemed to be more advantageous with respect to the operation time, the length of hospital stay, and cost.
