To evaluate the relationship between coronary artery disease(CAD) and the various levels of lipid and lipoproteins, we performed coronary angiography to the patient, who were suspected coronary artery disease from January 1988 to August 1989. And compared it with normal control group. The number of control group were 41(21 men, 20 women), and the patient group were 52(42 men, 10 women). The age was not differ between two groups. The results were as follows; 1. In CAD group, the plasma concentration of total lipid, triglyceride, total cholesterol, phosphlipid, and TC/HDL ratio were significantly higher than in control group. But, though, the concentration of HDL was lower in CAD group, had no significant difference between two groups. 2. The severity of CAD were well correlated with total lipid, cholesterol, LDL, trigylceride, phospholipid, TC/HDL, LDL/HDL levels. HDL level didnt's show significant correlation with the degree of CAD. We concluded that total lipid, cholesterol, trigylceride TC/LDL ratio were valuable markers of CAD in Korean, but futhur studies of lipoproteiins and other risk factors in the large population will be recommended.

불연속 지형을 지나는 천수 흐름을 해석할 수 있는 Hwang의 기법이 채택된 수치 모의를 댐 붕괴 흐름에 의한 직립 홍수터의 범람 실험과 비교하였다. 모의 결과는 저수지, 저수로, 홍수터로 이루어진 실험 수로에서 측정한 결과와 잘 일치하였다. 특히, 댐 붕괴 흐름이 직립 홍수터로 차고 빠지는 과정이 잘 모의되었다. 흐름 저항의 종류에 따른 모의 결과의 차이는 미미하였다. 이 연구를 바탕으로 도심 하천의 범람 예측에서 정확도를 높일 수 있을 것으로 기대된다. Numerical simulation with Hwang’s scheme, which can analyze shallow-water flow over discontinuous topography, was compared with a laboratory experiment of flooding on a perpendicular floodplain with dam-break flows. The simulation results were in good agreement with the results measured in an experimental flume with a reservoir, channel, and floodplain. The wetting and drying process on a perpendicular floodplain with a dam-break flow was particularly well simulated. The difference in simulation results according to the type of flow resistance was insignificant. The results of this study are expected to improve the accuracy of predicting inundation in urban rivers.

Background: The outcome of hepatitis B virus (HBV) infection after liver transplantation (LT) was improved by hepatitis B immunoglobulin (HBIG) and nucles(t)ide analogue (NUA). However, HBV recurrence after LT is critical because the recurrence is occasionally accompanied by a progressive destruction of graft and poor survival. The aims of this study were to investigate the significance HBV recurrence and identity factors associated with HBV recurrence. Methods: From October 1999 to February 2011, a total of 2684 consecutive LT recipients who underwent HBV-associated LT were retrospectively enrolled from 7 transplantation centers in Korea. Results: Prophylaxis regimens were HBIG monotherapy (67.7%) or a combination of HBIG with NUA (22.3%). The recurrence rate of HBV was 6.1% (164 recipients) during mean follow-up duration of 10.9 years. The median time from transplantation to recurrence was 2.1 years (0.1-7.9 years). Of the 1,071 patients with hepatocellular carcinoma (HCC) prior to LT, 155 patients (14.5%) had HCC recurrence after transplantation, and 48 patients (31.0%) had HBV recurrence. Of the 48 patients with recurrence of both HBV and HCC, 25 patients (52.1%) experienced HBV recurrence after HCC recurrence. In the multivariate analysis, pretransplant HCC, pretransplant HBV DNA above 5.5 log copies/mL was independent clinical factors influencing HBV recurrence after LT. The mortality rate among the recipients with HBV recurrence was 34.1% (56 recipients). Mean overall survival was 6.4 years in the HBV-recurrence group and 9.9 years in the HBV-nonrecurrence group (p<0.001). HBV recurrence was not an independent prognostic factor for overall survival. HCC recurrence was the most important factor for overall survival. Conclusions: The overall outcome of LT in HBV-related liver disease was excellent with the current prophylaxis regimen Choon Hyuck David Kwon,8 Suk-Koo Lee8 Pretransplant HBV DNA and HCC were important factors for HBV recurrence. HBV recurrence after LT did not significantly influence on the overall survival without combining of HCC recurrence.

Son and Lover 에 있어서 自我保存과 共存

김인수,황소부,고석기 慶尙大學校 1981 論文集 Vol.20 No.2

Sons and Lovers might be called the first great fiction which was written out of the living conditions of English working classes. Eastwood, Lawrence's native place, was a coal-mining area. Lawrence's direct experiences out of the life of coal-mining labourers and their family had a great influence on and vitalize his work. Lawrence, as an artist, from the beginning to the end, was deeply engaged in exploring his peculiar ego and completing it more than accomplishing art. Tringle relation―the trouble process of the son Paul who wanders between his mother and his lovers and agonizes over his potential repulsive mind against his love―is not a simple one but a Freudian one. Human conflict, frustration, failure and antagonism ar shown here. Lawrence write with hatred Miriam's mental bias towards disregarding flesh. Sons and Lovers, Lawrence's representative and famous work, is realistically translated the dramatic parts of his growth period into art. In the work, there are many elements foreshowing Lawrence's future development. Paul, the hero of the novel, must keep the independence of his own real self from other's and coexistence relation with others' souls in order to enjoy the real freedom, health and animation of his own self. Otherwise, there are only constant conflict, restriction and strifle between his own real self and others'.

황충주,김석현,길재경 대한치과교정학회 1997 대한치과교정학회지 Vol.27 No.2

두경부 자세는 생리적 활동의 기능적 요구에 의해 영향을 받으며 두개 안면 골격의 형태학적 발육에 직접 혹은 간접으로 영향을 미치는 것으로 알려져 있다. 대부분의 연구에서 안모형태와 설골의 위치, 두경부 자세는 서로 매우 높은 상관 관계를 나타내며, 특히 하악골의 전후방 위치가 두경부 자세와 가장 큰 상관 관계를 가지는 것으로 알려져 있다. 이와같은 연구에서는 대부분 연구대상을 Natural Head Position(NHP)으로 유도하였으며 여러 연구자들에 의해 NHP의 재현성이 매우 높다고 알려져 있으나, 교정환자를 위해 통법의 두부방사선 사진을 찍은 경우에는 어떠한 상관관계가 있는지에 대해선 연구가 적은 실정이다. 이에 본 연구에서는 여러 안모 유형의 성인 여자 환자를 대상으로 수직 기준선을 나타내는 수직선 추를 이용하여 통법에 따라 채득한 치료전 측모 두부방사선 사진을 이용하여 Wits와 ANB을 기준으로 골격성 부정교합군을 I, II, III로 분류하였으며 각 군별 20명씩 선택하여 두경부 위치와 설골 위치의 부정교합 분류에 따른 상관성 여부를 알아보아 다음과 같은 결론을 얻었다. 1. 두개저에 대한 설골의 수직적 위치 비교시 Cl II에 비해 Cl III에서 설골이 더 하방 위치하였다. 2. 경추에 대한 설골의 전후방 위치 비교시 Cl II에 비해 Cl III에서 더 전방 위치 하였다. 3. 하악에 대한 설골의 수직적 위치는 Cl I, II, III 간에 통계학적 유의차가 없었다. 4. 악골의 전후방 관계를 나타내는 ANB, Wits와 설골의 위치 사이에는 통계학적 상관관계를 관찰할 수 없었다. 5. Cl II에서 나타나는 상대적인 두부 신전(extension)은 Bjork Sum, ANB와 역상관계를 나타냈다. 6. Cl II와 Cl III에서 Post to Ant Facial Height과 NSL/VER은 수상관관계를 나타냈다. It has been known that head posture may influence directly and/or indirectly the growth and development of craniofacial morphology and can also be influenced by the functional demand of physiologic activity. It was reported that facial morphology has close relationships with hyoid bone position and head posture. In many previous studies, Natural Head Posture(NHP) was guided, and also it was shown that NHP has high degree of reproducibility. Otherwise, There was few study about the relationship of head posture, with routine cephalometric film which is used for clinical orthodontic purpose. In this study according to the Wits and ANB of initial cephalometric film which was taken with vertical pendulum as representative of true vertical reference line. We classified the subjects which is comprised of 60 adult female patients into Class I, II, III (Cl I, II, III)and we tried to find out the correlation of head posture and hyoid bone position according to the classification of malocclusion. As a result of our research, we found the followings. 1. In comparison of vertical position of hyoid bone relative to the cranial base the position of hyoid bone of Cl III was lower than that of Cl II. 2. In comparison of anteriorposterior position of hyoid bone, relative to the cervical column. The position of hyoid bone of Cl III was more anterior than that of Cl II. 3. In comparison of vertical position of hyoid bone relative to mandible. There was no significant correlation among the groups of malocclusion. 4. ANB and Wits showed no significant correlation with hyoid bone position. 5. The relative extension of head, which was noted in Cl II, showed negative with Sum, ANB. 6. In Cl II and Cl III, Post to Ant facial height showed positive correlation with NSL/VER.

In order to know the possibility of utilizing the sister chromatid exchanges as an index which could evaluate the effect of organic solvents on the health in industrial workers, the authors studied the effects of the inductivity of sister chromatid exchanges in peripheral lymphocytes from 90 female workers expoxed to organic solvents and 20 non-exposed female workers. The results obtained were as follows : 1. The frequency of sister chromatid exchanges in peripheral lymphocytes from 90 female workers exposed to organic solvents was significantly increased in comparison with 20 control subject. 2. The frequency of sister chromatid exchanges was significantly increased in the workers who were employed in the manufacture of plastic materials than the other manufactures. 3. There were no significant differences in the frequency of sister chromatid exchanges by carriers of the exposed workers.

彈性理論에 依한 鋼뼈대構造物의 連續型 最適 設計에 關한 硏究

황학주,김석기,이원복 연세대학교 산업기술연구소 1975 논문집 Vol.6 No.1

Linear Programming is the most highly developed operations research algorithm currently in use. Virtually every reputable computing center has a version of the simplex method. This availability of a programmed algorithm greatly enhances the choice of linear programming. Linear Programming is also capable of handling exceedingly large problems, which of course is necessary if one wishes to optimize large structures. The linear programming formulation is conceptually more palatable to the mode of thought of the structural engineer than are some of the esoteric operations research algorithms. In this paper, therefore, a metrix set of nonlinear working stress constraints is derived by the stiffness method, following the network-topological approach and incorporating the working stress interaction conditions. And then, this nonlinear constraint set is transformed into the constraint set of a successive linear programming problem using the Taylor series expansion. The formulation is greatly enhanced by evaluating the Jacobian of the constraint vector function. The objective function of the nonlinear programming formulation for minimum volume design is derived by the relation between area and moment of inertia, and this nonlinear objective function is transformed into the linear by the Taylor series expansion.

객체지향 클래스계층구조의 확장에 관한 연구

김대원,황석형,박정호 선문대학교 첨단과학기술연구소 1998 첨단과학기술연구소 논문집 Vol.3 No.-

객체지향설계에는 여러 가지 잇점이 있으나, 그 중 하나로서, 기존 성과물의 재이용을 들 수 있다. 유효한 재이용 수법 중의 하나로서, 본 논문에서는 클래스 계승구조를 바탕으로 하는 재구성법에 대해 논한다. 클래스 계층구조의 재구성에 관한 종래의 연구[1,2,4,5]에서는, 계승계층만을 주목한 재구성법에 관한 연구[1,2]가 많았고, 집약계층까지 주목한 연구는 클래스 계층구조의 등가성과 등가변환수법에 관한 연구[4,5]가 있다. 기존의 어플리케이션과 상위호환이 되는 확장 어플리케이션을 구축할 경우, 확장어플리케이션의 요구사양에 적합하도록 클래스 계층구조를 확장·재구성할 필요가 있다. 본 논문에서는, 이와같은 클래스 계층구조의 확장재구성법 의 프레임워크를 제안한다. 우선 클래스 계층구조를 보다 형식적인 형태로 정의하고, 이론적인 논술이 가능토록하기 위해서 클래스 계층구조를 유한유향그래프 형태로 나타낸 클래스 계층그래프를 정의한다. 또한. 클래스 계층그래프 간의 순서관계로써 객체확장관계를 정의한다. 객체 확장관계에 있는 두 개의 클래스 계층 그래프로부터 각각 생성 되는 객체는 포함관계에 있다. 객체확장관계를 만족하는 클래스 계층그래프의 재구성법으로써, 5가지 기본 조작을 정의하고, 정의된 기본 조작만을 이용하여 클래스 계층그래프를 확장 재구성할 수 있음을 보이기 위해, 기본 조작의 정당성 및 완전성을 증명한다. In recent years there has been renewal of interest in the reorganization and evolution of class hierarchy structure for object-oriented system development and programming[l,2,4,5]. Numerous attempts have been made to show the algorithms and heuristics to produce "good" and "reusable" class [1,2,4,5]. One of the most common forms of reorganization and/or evolution involves the extension of an existing system by addition of new classes or the addition of attributes to the original objects, and so on. In an extreme case, a class reorganization might reflect not only the extension and reclassification of existing objects, but also structural changes to the original objects. In this paper, we arc concerned with the inheritance and aggregation hierarchies, and define Object Extension relationship between the class hierarchy graphs. And also we present five basic transformations which form a foundation for extension or reuse of existing systems based on the object-extending. The set is proven to be correct and complete.

본 연구는 한국과 베트남 사람들의 정서 체험에 관한 연구이다. 정서의 보편성과 문화적 변산성에 관한 이론적 연구를 위한 자료를 수집하기 위한 목적으로, 사람들이 다양한 정서 상태들을 경험할 때 느끼는 생리적 반응, 언어적 표현, 행동 반응, 주관적 느낌 및 그러한 정서를 유발하는 상황에 초점을 두어 베트남 사람들과 한국 사람들의 정서 체험 내용의 공통점과 차이점을 알아보았다. 베트남에서는 국립 베트남 대학교와 국립 호치민 대학교에 재학중인 215명이 본 연구에 참여하였고, 한국에서는 60명의 국립 서울대학교 학부생들이 참가하였다. 기쁨, 슬픔, 공포, 분노의 네 가지 정서가 정서 체험에 관한 자기-보고 질문지를 사용하여 연구되었다. 결과는 다음과 같다. 첫째, 특정한 정서를 유발하는 원인이 되는 선행 사건들의 보편성을 밝혔다. 다음으로, 다양한 정서를 체험할 때 나타나는 반응들의 패턴에 있어서 문화간 변산성이 나타남을 확인하였다. 세 번째로 여성과 남성의 정서 체험의 내용에서 몇 가지 흥미로운 차이점들이 발견되었다. 마지막으로 후속 연구를 위한 시사점들이 논의되었다. The emotional experiences of Koreans and Vietnamese were studied. In order to collect the data for the purpose of conducting a theoretical study on universality of emotions and cultural variations, the similarities and differences in the various aspects of emotional experiences of Koreans and Vietnamese were examined, which included physiological responses, verbal expressions, behavioral patterns, subjective feelings, and the antecedent events that were the causes of the emotional experiences. 215 Vietnamese undergraduates from Vietnam National University and Ho Chi Min University and 60 Korean undergraduates from Seoul National University participated in this study. Using a self-report form, emotional experiences of joy, sadness, fear, and anger were examined. As the result, universality of antecedent events for specific emotions was confirmed. Cultural variations in the emotional response patterns were confirmed as well. Finally, some interesting sex differences in emotional experiences were found. Implications and suggestions for the future study were discussed.
