Wasabi 정유는 다음과 같이 추출하였다. wasabi 분말에 같은 양의 물을 넣고 1시간 방치 후 물을 더 넣고 증류하였다. 증류분에 디에틸 에테르를 넣고 wasabi 성분을 추출하고, 다음에 에테르를 증발시켜 노란색의 정유를 얻었다. 이 정유는 wasabi의 독특한 향기를 나타내었다. 이 정유의 농도가 200, 400 및 600ppm인 배지에서 Lactobacillus plantarum을 배양하였다. 200ppm과 400ppm을 함유한 배지에서의 유도기는 각각 24시간과 39시간이었으며, 유도기 후에는 박테리아가 자랐으나 600ppm을 함유한 배지에서는 박테리아가 억제되어 48시간이 경과하여도 증식하지 않았다. 또한 600ppm을 함유한 배지의 억제율은 시간이 증가함에 따라 점차 증가하였다. The essential oil of wasabi was extracted as follows. The same amount of water was added to wasabi flour and the mixture was allowed to stand for a hour. More water was added to it and the mixture distilled and the distillate was extracted with diethyl ether. A yellow essential oil was obtained after ether was evaporated. The obtained essential oil had the same odor as original wasabi. Lactobacillus plantarum was incubated at 30°C in a medium containing 200, 400, and 600 ppm of the essential oil, respectively. The lag phase in medium with 200 and 400 ppm was 24 and 39 hr and after that times the bacteria started to grow. However, L. plantarum in a medium with 600 ppm was inhibited to grow up to 48 hr and inhibition percentage of the 600 ppm medium continuously increased with time.

Purpose : We evaluated and analyze the injury of the professional soccer player which would be helpful data for prevention of injury. Materials and Methods : Thirty-four professional soccer players were followed prospectively for one year and obtained injury exposure rate. We divided the injuries according to the position of the players incurred average 10 injuries for one year and the injury exposure rate was 2.9/1000hours, mostly strains and sprains of the lowre extremities. According to the player's position, the injured area and injury mechanism were different, Defence-Fielder and Mid-Fielder were more vulnerable to injury, 43% and 41.8% respectively, and mainly thigh and ankle injury. But Forward injury was less frequent and mainly leg and knee injury. In Goal-Keeper, neck and upper extremity injury was pre-dominant. Acute traumatic injury was 93% and recovery time was average on day, however, chronic overuse injury was less frequent but much longer time was required for recovery. Conclusion : The overuse injury is preventable by improving the environment and training program so that more attention is required.

Ar과 N₂?가스가 혼합된 분위기에서 반응성 스퍼터링 방법에 의하여 TiN 박막을 증착하였다. N₂ 가스의 농도는 화학양론적으로 TiN이 형성되는 조건에 맞도록 조절하였으며, 기판의 온도는 실온에서 부터 700℃의 범위내로 유지하였다. (111) texture 구조를 가지면서 화학양론적으로 Ti??N??인 박막은 기판의 온도가 600℃ 이상에서 형성되었고, 기판의 온도가 600℃ 이하에서는 형성된 박막은 N-과다형이었다. XRD, XPS 및 RBS 분석 결과 TiN 박막의 조성비는 기판의 온도에서 다소 의존하였으나 약 5% 이내에 불과하였다. TiN 박막의 면저항은 기판온도의 증가에 따라 감소하였고, 기판온도가 600℃에서 증착된 TiN 박막의 면저항능 14.5Ω/□ 였고, Ar―가스 분위기에서 700℃로 30초간 열처리한 후는 8.9Ω/□ 이었다. 따라서 반응성 스퍼터링방법에 의하여 형성되는 양질의 TiN 박막은 기판온도가 600℃이상이 최적조건임을 알았다. Titanium nitride (TiN) films were prepared by reactive sputter deposition in mixed gas of Ar+N₂?. The volume percentage of N₂ in the working gas was chosen so as to grow stoichiometric TiN films and the substrate temperature during film growth was set from room temperature to 700℃. stoichiometric Ti??N?? films with (111) texture were grown at temperatures over 600℃, while films prepared at temperatures below 600℃ showed N-rich TiN. The composition x and y in the Ti??N?? films determined by XPS and RBS varied within 5% with the substrate temperature. The sheet resisstance of the TiN films decreases as the substrate temperature increased. TiN film prepared at 600℃ showed 14.5Ω/□, and it decreased to 8.9Ω/□ after the sample was annealed at 700℃, 30 sec in Ar-gas ambient by RTA. By far, high quality stoichiometric TiN films by reactive sputtering in the mixed gas ambient could be prepared at substrate temperature over 600℃.

The objective of this study is to predict the high risk group of coronary artery disease from body mass index, blood pressure, fasting blood sugar and serum lipids level using the method of discriminant analysis. Variables with significant difference between coronary artery disease group and normal group were HDS-C, LDL-C/HDL-C, LDL-C, and TG. But the acuity did not exceed 70% in any single variable. As the results of discriminant analysis, statistically significant discriminant variables were HDL-C, T-chol, FBS and TG. The discriminant equation was(Y) = -0.06759(HDL-C) + 0.01498(T-chol),+0.01923(FBS) - 0.01421(TG) + 0.5187, and the overall discriminant power using the above 4 variables was 79.3%

하진렬,최경민,김지아,원태진,신동수,이민주,안철진 昌原大學校 基礎科學硏究所 2002 基礎科學硏究所論文集 Vol.14 No.-

The ring expansion chemistry is one of the most important methods to prepare five-and six-membered heterocylic compounds. We have studied about γ-lactam ring expansion with stereoselectivity from β-lactam derivative. To do this chemistry, proton of N-benzyl group in β-lactam derivatives is eliminated by LDA and make carbanion.This anion make unstable 4-membered lactam intermediate, and then the ring is opened by homo clevage or hetero cleavage for releasing ring strain, followed by recyclization to one carbon to make γ-lactam ring with stereoselectivity in β-, γ- positions.

Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

Past sea surface temperature of the East Sea inferred from alkenone

Lee, Kyung-Eun,Kim, Kyung-Ryul The Korean Society of Oceanography 2002 Journal of the Korean Society of Oceanography Vol.37 No.1

We measured the alkenone concentration of bulk sediments from a piston core collected from the Ulleung Basin in the East Sea in order to reconstruct past sea surface temperatures (SST). Sediment ages are well constrained by AMS $^{14}C$ dates of the planktonic foraminifera Globigerina bulloides. Coretop alkenone SST calibration with modern surface temperatures and sediment trap dat (Hong et al., 1996) indicate that the SST estimated from alkenones most likely represent the temperatures of late fall. Downcore variations in the alkenone saturation index indicate that between 19 and 15 kyr BP the surface waters were about $3^{\circ}C$ warmer than today. Between 15 and 11 kyr BP, the temperatures were about $3^{\circ}C$ lower than today. A rapid SST increase of about $3^{\circ}C$ occurred at approximately 10 kyr BP. After considering the factors which might influence the SST reconstruction from the $U^{k'}_{37}$ values, we conclude that the alkenone temperature estimates are reliable. The reason for glacial warming in the East Sea is not clear, although there is a possibility that it could be caused by shift in the season of maximum alkenone production from summer during the last glaciation to late fall during the Holocene. Cooling between 15 and 11 kyr BP may be due to inflow of cold water into the East Sea such as via the Oyashio Current or ice-melt water. Warming at the early Holocene could be due to inflow of the Tsushima Current into the East Sea through the Korea Strait.
