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.

전통(재래)시장의 침체는 단순히 열악한 물리적환경과 소비자들의 소비형태의 변화만이 아니라 사회적, 물리적, 경제적, 문화적, 환경적부문의 쇠퇴가 함께 진행되면서 나타난 현상이라고 할 수 있다. 본 연구는 다양한 쇠퇴측면에서 접근하는 다계층 의사결정모형(AHP)을 구축하여 전통시장의 침체요인에 기반을 둔 활성화 방안을 도출하고자 하였다. 연구결과 전문가들은 소비자들의 유입을 통하여 시장 및 상인에게 경제적으로 도움이 될 수 있는 지원방안과 상가 및 상인들의 역량을 강화시키는 것이 전통시장 활성화에 큰 도움을 줄 것으로 인식하고 있었다. 세부적으로는, 전문가들은 현재 부분적으로 시행하고 있는 전통시장 상품권인 온누리상품권 유통확대, 전통시장의 통합적 운영조직 구성, 공동마케팅 운영, 셔틀버스의 운행을 통한 접근성 향상과 수변공간과 쉼터 등을 조성하여 쇼핑 환경을 향상시키는 것이 중요하다고 인식하고 있는 것으로 나타났다. 반면에 정부와 지방자치단체가 중점적으로 지원해온 문화적 측면의 재생방안 및 아케이드 설치, 보행로 정비등 물리적재생은 전통시장의 활성화에 큰 도움이 되지 않는 것으로 인식하고 있다. 따라서 전통시장의 효율적 활성화를 위해서는 상인역량강화 및 경제적재생 측면의 활성화를 중심으로 하는 방향으로의 전환이 필요한 것으로 나타났다.

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.

This study was performed to assess the radiopacity of a variety of root canal sealers according to the Specification concerning root canal sealers. Ten materials including Tubli-Seal™, Kerr Pulp Canal Sealer™, AH 26^(R), AH plus^(R), AH plus jet™, Ad seal™, Sealapex™, NOGENOU™, ZOB seal™, Epiphany™, and dentin were evaluated in this study. In the first part. densitometric reading of an each step of aluminum step wedge on occlusal film was performed at different voltage and exposure time. In the second part, ten specimens were radiographed simultaneously with an aluminum step wedges on the occlusal films under decided condition. The mean radiographic density values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained 1 Among the various conditions, the appropriate voltage and exposure time that meet the requirement density was 60 kVp at 0.2 s 2 All of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards. 3 The radiopacity of materials increased as thickness of materials increased. 4 The mm Al value of each specimen at 1mm in thickness has a significant difference in the statistics. It suggests that root canal sealers have a sufficient radiopacity that meet the requirement. 다양한 근관전색제는 방사선 사진상 주위 해부학적 구조와 구별될 만한 방사선 불투과성을 나타내야 한다 따라서 이런 물질들이 근관에 충전될 때의 방사선 불투과성 정도를 평가해야 할 필요성이 대두되고 있다. 본 실험에서는 다양한 근관전색제들의 방사선 불투과성을 평가하고자, 방사선 노출조건에 따른 aluminium step wedge에 대한 광학 밀도를 알아보고, 그 중 적절한 노출조건을 선택하여 수종의 근관 전색재의 방사선 불투과성 정도를 알루미늄 두께로 환산하여 비교해 보고자 한다. 방사선 불투과성의 기준을 위해 11개의 step으로 구성된 aluminum step wedge을 사용하여, 60kVP, 70kVp관전압 상태에서 각각 0.2, 0.3, 0.4초 그리고 0.2, 0.3, 0.33초의 꼭 노출시간으로 교합필름상에서 방사선 촬영후 적절한 노출 조건을 구하였다. 직경 5mm 각각의 두께 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm인 10종 (Tubli-Seal™, Kerr pulp Canal Sealer™, AH26^(R), AHplus^(R), AH plus jet starter kit™, Ad seal™, Sealapex™, Nogenol root canal sealer™, ZOB seal™, Epiphany™)의 근관전색재 시편을 각 재료와 두께당 10개씩 제작한 후, 동일한 두께의 상아질 시편, aluminum step wedge와 함께 정해진 노출시간에 따라 방사선 촬영을 하였다. 모든 필름은 자동현상기로 현상하였다. 시편의 방사선 흑화도를 densitometer로 5회 반복 측정 후, 평균값을 구하여 알루미눔 두께로 환산하였다.얻어진 정보를 분석하여 다음의 결과를 얻었다. 1 관전압 60 kVp에서 노출시간 0.2, 0.3, 0.4초, 70 kVp에서 0.2, 0.3, 0.33초로 변화를 주어 방사선 촬영을 하였을 때 흑화도가 ISO No. 6876 규격에 가장 적합한 것은 60 kVP, 0.2초 일 경우였다. 2 측정된 근관 전색제의 방사선 불투과성은 2.29 mm Al (N0GEN0L)로부터 13.69 mm Al (AH Plus jet)까지 다양하게 나타났으나, 모두 ANSI/ADA specification (2000) 또는 ISO No. 6876 (2001) 규격이 제시한 최소한 3mm Al 이상의 방사선 불투과성을 지녀야 한다는 기준에 적합하였다. 3 재료의 두께가 증가할수록 방사선 불투과성은 증가하지만, 정비례하지는 않았다. 4 각 실험재료의 1 mm 두께의 시편에 대한 mm Al값들은 통계적으로 유의한 차이가 있었다. 이상의 결과는 본 실험에 사용된 수종의 근관 전색재는 모든 규격에 적합한 방사선 불투과성을 가지고 있음을 시사한다.

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'.

The surgically created arteriovenous fistula has become the method of choice in achieving vascular access for maintenance hemodialysis. The authors performed 70 arteriovenous fistulas for angioaccess in 65 patients with CRF at the Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period form August 1990 to November 1991. There were 4 cases of early obstructions due to inadequate vein in 2 cases, inadequate artery in 1 case and technical failure in 1 case. In 3 cases except 1 case who was transferred to other hospital, re-AVF were tried with successful outcomes. There were 2 cases of minor complications (wound infection and arm swelling due to venous hypertension) which were managed conservatively with successful outcomes. During the mean follow up of 8 months in 59 patients whore are not expired or lost during follow up, 3 cases of late thrombosis were occured with fistula patency rate of 94.9%. The authors consider the 'anatomical snuffbox' arteriovenous fistula as a primary choice and consider another method if it is not possible.
