Objectives : The purpose of this study was to gain an understanding of the effects of three exercise types on anthropometric and serum lipids and physiological index factors, which are known to be the three risk factors of cardiovascular disease in male workers. Methods : The experimental study period was 12 weeks. In this study, 30-40's males (N=31) were assigned to 3 experimental groups: regular aerobic(treadmill walking) exercise group, regular anaerobic(muscular endurance) exercise group, irregular aerobic & anaerobic exercise group and a control group using a stratified random assignment method. Results : In relation to anthropometric factors, the regular aerobic & anaerobic exercise groups showed significant decreases in Weight, Broca's index, WC, BMI, WHtR, WHpR and HRrest. With regard to the serum lipid factors, the TC was decreased, but the HDL-c increased among the regular aerobic & anaerobic exercise groups. However, no significant difference was found between the other groups in respect to the LDL-c and TG. Considering the physiological factors, the TC/HD-c, TC-HDL/HDL-c, LDL-C/HDL-c and NON-HDL-c ratios were decreased, but the HDL-c/TC ratio increased among the regular aerobic & anaerobic exercise groups. The TG/HDL-c and HDL-c/LDL-c ratios showed no significant differences between the groups. These results indicated that the positive change for each factor is much larger in the regular exercise groups, especially in the anaerobic exercise group. Conclusions : The results indicate that not only regular aerobic exercise, but also regular anaerobic(muscular endurance) exercise could be utilized in lessening the deleterious effects of the risk index factors for cardiovascular disease.

Rat lipoprotein-deficient plasma possessed a lipid tramsfer inhibitory activity when it was added to purified human plasma lipid transfer protien, while it lacked a lipid transfer activity. Incubation of whole rat plasma with partially purified human lipid transfer protein resulted in big changes in lipid distribution of rat plasma lipoproteins. There w was a 4-fold increase in cholesteryl ester(CE) and 4 47 % reduction in triglyceride(TG) in very low density lipoproteins after 2싹lour incubation. In high density lipoprotein $2(HDL_2)$ there was a 9­fold increase in TG and 33 % reduction in CEo HDL3 had 82 % reduction in CE. The result indi­c cates that the absence of the lipid transfer activity in rat plasma can be ascribed not to the inability of rat lipoproteins to serve as substrates but to the lack of 야Ie lipid transfer protein in rat plasma. Th­e erefore, species differences in lipid transfer betwe­e en lipoproteins should be taken into consideration to interpret results of studies on lipoprotein m.eta­b bolism using rats.

This study aims to provide the relevant basis upon which prediction of dyslipidemia should be made based on body information. Using the National Health Insurance big data (3,312,971 people) canonical correlation analysis was performed between body information and lipid-profile. Body information included age, height, weight and waist circumference, while the lipid-profile included total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol. As a result, when the waist circumference and the weight are large, triglycerides increase and HDL cholesterol level decreases. In terms of age, weight, waist circumference, and HDL cholesterol, the canonical variates (the degree of influence) were significantly different according to sex. In particular, the canonical variate was dramatically changed around the forties and fifties in women in terms of weight, waist circumference, and HDL cholesterol. The canonical correlation results of the health care big data presented in this study will help construct a predictive model that can evaluate an individual's health status based on body information that can be easily measured in a non-invasive manner.

Objectives: In order to determine the effect of CPs, experimental studies were performed in hyperlipidemia humans. The contents of serum total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine were measured. Methods: We made a comparative study of total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine during one month off and on for twenty patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University from December 2002 to July 2003. Results: The following result were obtained: 1. The serum TG and total cholesterol of patients who took CPs for one month showed significant (p<0.01) decrease. 2. The serum HDL-cholesterol and LDL-cholesterol of patients who took CPs for one month showed significantly increase in HDL, and decrease in LDL (p<0.05). 3. The serum AST/ALT and BUN/creatinine of patients who took CPs for one month showed no significant effects. Conclusions: According to the results mentioned above, the effects of CPs on serum triglyceride and total cholesterol of hyperlipidemia patients were significantly confirmed for decreasing effects.

Dietary habits and serum lipid composition of 80 hospitalized patients with cerebrovascular disease (CVD) were compared to those of normal subjects. CVD patients were significantly higher in BP, serum cholesterol and triglyceride levels and low4r in HDL-choelsterol which resulted in the higher ratio of serum chol/HDL-chol than normal. Patients were also lower in the relative amount of HDL fraction by electrophoresis but were higher in LDL fraction and the ratio of LDL/HDL . In Korean, the high levels of serum chol, TG and LDL with low level of HDL as well as high BP could be one of the important causing factors of CVD. However, dietary habits of patients were not significantly different from those of normal . There is a possibility that patients might have controlled their dietary habits after they realized the severeness of disease.

컴퓨터나 각종 전산망의 정보를 보호하기 위해서 가장 안전한 수단은 정보의 직접적인 보호라고 할 수 있는데, 정보사회로 갈수록 지적 재산(IP ; Intellectual Property)이나 기타 다른 중요한 정보의 네트워크를 통한 교류가 활성화될 것이다 본 연구에서는 이러한 보호의 대상이 되는 정보를 암호화시킬 수 있는 알고리즘에 대한 HDL(Hardware Description Language) 구현을 목표로 한다. 현재까지 수많은 알고리즘이 개발되어 왔지만 DES(Data Encryption Standard)가 가장 기본적이고 모든 블록 암호 알고리즘의 기본이 되기 때문에 본 논문에서는 DES에 대한 기본적인 구조를 제시하고 그에 대한 Verilog-HDL 구현을 목표로 하였다. HDL로 설계된 회로는 LC-0.35um 표준 셀 라이브러리를 사용한 synopsys 툴을 이용하여 합성되었다. 전체 회로의 동작 주파수는 약 236MHz고 예상되고 초당 15104비트의 데이터를 암호화 시킬 수 있다.

Plasma high-density lipoprotein cholesterol (HDL-C) levels are inversely correlated with the risk of cardiovascular disease, and are known to increase with repetitive exercise. In the current study, HDL fractions from athletes' sera were isolated and compared as a function of the type of sport (runners [n = 10], throwers [n = 10], wrestlers [n = 10], and weight lifters [n = 8]), and as an age- and gender-matched reference group (n = 14). Among athletes, HDL from runners had the strongest antioxidant activity. Immunodetection showed that runners and wrestlers had the highest levels of apoA-I and lowest levels of apoA-II in their HDL. Electron microscopy also revealed that HDL2 of runners and wrestlers were the largest in size. In conclusion, although all athlete groups had significantly better serum lipid/lipoprotein profiles than the reference group, runners and wrestlers had the most desirable lipoprotein function and structure, including antioxidant activity, HDL-associated enzyme activities and increased particle size.

Effect of saponin fraction of ginseng C.A. Meyer on blood serum lipoprotein distribution of high cholesterol fed rabbits for two to four weeks was investigated. A. significant increase of very low density lipoprotein(VLDL) and low density lipoprotein(LDL) occured while high density lipoprotein(HDL) were decreased in the blood of both groups which were fed high cholesterol diet with (test group) and/or without ginseng saponin(control group) for 2-4 weeks. However the degrees of VLDL and LDL increase and HDL decrease were relatively small in ginseng administered group compared with control group. This suggests that the hypocholesterolemic action of the saponin might be brought about by decreasing the raised VLDL and LDL level and increasing the lowered HDL level.
