Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

We investigated reproductive cycle of the turban shell. Lunella coronata coreensis with the histological preparation of gonads and the gonadosomatic index (GSI). The turban shells were collected at the intertidal zone of Hamdeok in Jeju-Do from December. 1995 to October. 1996. The gonad was located on the surface of the liver below the stomachal caecum Posterior spiral meat part of the shell. GSI value began to increase from May as water temperature increased and reached its maximum value in August both male and female which were 56.94 and 61.88. respectively. GSI started to decrease from September thereafter. maintaining relatively low value from January to March. The reproductive cycle of L. coronata coreensis could be grouped into five successive developmental stages : multiplicative stage (female: February to April. male. April to May). growing stage (female: April to June, male: June). mature stage (female: June to August, male: July to August). ripe and spawning stave (August to September). And degenerative and recovery stage (October to March). The spawning of the turban shell occurred from August to September and the main spawning period appeared in September. The turban shell. L. coronata coreensis appeared to be gonochoristic species. Sex ratio of female to male was 1.6 : 1.0 (P > 0.05).

To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.

Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end point is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average date reception rate. At that time, we used evaluation parameters such as node's mobility -stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

For the purpose of investigating the positive rate of rubella antibody and sero-conversion rate after rubella vaccination, 863 high school students of the two regions were studied from April 21st, 1996 to September 20th, 1996. The main results were as follows; 1. Positive rate of IgG in male was higher than in female, and the rate of IgM was also higher in male than in female. 2. Positive rate of IgG by blood type was similar, but positive rate of IgM was higher in AB type than the others. 3. Positive rate of IgG by vaccination was similar to all groups, but positive rate of IgM was higher in which was not vaccinated group. 4. Positive rate of IgG and IgM, having vaccination card, was less than which was not having vaccination card. 5. Those who were vaccinated acquired IgG(+) regardless of an existence of IgG antibody, and 28.3% of IgG(-), IgM(+) male who was not vaccinated became IgM(+), IgG(+) after 3months later. As a result positive rate of male was higher than female. The author conclude that vaccination is necessary to prevent from rubella for them.

吳世旭,朴榮哲,趙鏞培 東亞大學校 海洋資源硏究所 1989 硏究論文集 Vol.2 No.1

The epoxy resin plate and acryl plate (Both thichness:3mm) overlapped are loaded by Pin-Joint. The stress distribution, stress intensity factors and correction factor at crack tip with various demension of the specimen are as follows; 1. When the pin is loaded, the K₁value is increased remarkable in case that length of the crack is above 6mm. 2. Correction factor(F₁) is greatly dependent on the value of a/d, but not on the value of a/w or a/r. 3. When the pin is loaded, K₁value is highly decreased with decrease in crack length because of the compression load developed between pin and specimen. 4. When the pin is loaded correction factor(F) is remakable incresed as the distance of two holes are decreased.

Arthrobacter simplex의 Steroid △^1-dehydrogenase의 유도와 유도성 스테로이드의 성질

배무,오영주,민태경,이미경 이화여자대학교 생명과학연구소 1991 생명과학연구논문집 Vol.2 No.-

Arthrobacter simplex IAM 1660의 스테로이드 Δ^1-dehydrogenase에 대한 각종 steroid의 유도조건과 효과를 검토하였다. 그 결과 시험한 스테로이드 중 hydrocortisone이 가장 큰 효과를 나타냈고 progesterone, prednisolone, prednisone, androstendione의 순으로 유도효과를 보였고, 스테롤에 의해서는 유도효과가 낮았다. 유도 스테로이드의 특성으로는 스테로이드 모핵 C-3위가 수산기인 것보다 캐톤기이며 C-4위에 이중결합이 존재하고 스테로이드 D고리의 측쇄가 짧은 것이 유도효과가 높았다. 유도물질의 첨가시기는 대수증식기 초기가 최적이었으며 농도는 hydrocortisone의 경우 0.1%가 좋았으며 효소의 유도시간은 15시간이 최저이었다. 효소유도시 배양온도는 30℃가 가장 좋았고 초기 배양액의 pH는 6.5에서 8.0까지 큰 차이가 없었지만 pH6.5일 때 비교적 높은효과를 나타내었다. Hydrocortisone에 의해 유도된 균체효소의 Δ^1-dehydrogenase 수소반응의 기질특이성을 검토한 결과 progesterone, testosterone,cholestenone이 Δ^1-탈수소 반응산물로 전환되었다. Since steroid Δ^1-dehydrogenase synthesis has been known to be inducible, the mechanism of the enzyme induction of Arthrobacter simplex IAM 1660 was investigated. Among various steroids tested for inducers, hydrocortisone was the most effective inducer when hydrocortisone was used as a substrate for steroid Δ^1-dehydrogenase. Steroid Δ^1-dehydrogenase sysnthesis was effectively induced by progesterone, prednisolone and androstenedione, while the enzyme was less induced by cholesterol and not by phytosterols. The results suggest that the presence of 3-keto group and short side chain of sterodids are the favorable factors for the induction of the Δ^1-dehydrogenase synthesis. The enzyme was induced at the highest level when hydrocortisone was added at early log phase to the concentration of 0.01% of the culture and the culture was grown for 15 hours.
