본 연구는 황금새(Ficedula narcissina)의 여러 아종 중 한국에 도래하는 아종의 형태학적 특징과 봄·가을 이동 양상을 파악하기 위해 2005년 4월부터 2008년 5월까지 전남 신안군 홍도와 대흑산도, 일본 이리오모테섬에서 각각 실시하였다. 형태학적 분류 결과 한국에 규칙적으로 도래하는 아종은 F. n. narcissina이었으며, 한국 미기록 아종인 F. n. elisae와 F. n. owstoni의 기록을 확인하였다. 황금새 성조 수컷은 아종간 형태적인 차이가 명확하였지만 미성숙한 개체와 암컷 형태를 띠는 개체는 아종간 매우 비슷한 특징을 보였다. 1회 여름깃 수컷의 경우 아종 F. n. narcissina는 월동지에서 부분 깃털갈이를 하여 성조 수컷과 비슷한 반면, 아종 F. n. elisae는 태어난 이듬해 여름까지 깃털갈이를 하지 않아 성조 수컷과 형태적으로 뚜렷이 다르며, 오히려 성조 암컷과 비슷한 특징을 보였다. 이같은 형태적 다양성과 깃털같이 전략의 차이 때문에 한국을 통과하는 개체군의 아종 분류가 매우 어려운 것으로 보인다. 조사기간 중 황금새의 가장 빠른 도래일은 4월 13일, 가장 늦은 도래일은 5월 17일로 나타났으며, 가장 많은 개체수가 통과하는 시기는 4월 하순으로서 2008년 4월 24일에는 14개체가 관찰되었다. 그러나 황금새는 봄철과 달리 가을 남하 시기에는 전혀 관찰되지 않아 봄·가을 이동경로를 달리할 가능성이 있음을 보였다. From April 2005 to May 2008, morphological traits and migratory patterns among the subspecies of the Narcissus Flycatcher (Ficedula narcissina) were studied at Hong Island and Heuksan Island in Korea, and at Iriomote Island in Japan. The regular migrants was F. n. narcissina in Korea, but two unreported subspecies, F. n. elisae and F. n. owstoni were also recorded in Heuksan Island, Korea. In our study, Narcissus Flycatchers were spring migrants observed from 13 April to 17 May, and a total of 14 individuals was recorded as a peak day count on 14 April 2008. However, there was no record in the autumn migratory seasons in Korea. This result suggests that the Narcissus Flycatcher is probably an elliptical migratory species which uses different routes in spring northward and autumn southward migrations. In morphology, adult males had distinct morphological differences, but immature and female-typed individuals had very similar plumages among subspecies. First summer F. n. narcissina underwent partial moults in wintering places and became very similar in appearance to adult males. In 'contrast, because F. n. elisae does not undergo partial moults until the summer of the 2nd calendar year, immature males of F. n. elisae were very resemble not adult males but adult females in appearance. Such morphological variances and differences in moulting strategies among subspecies often prevented the identification of Narcissus Flycatchers to the subspecies level.

In this study, homogenized suspension polymerization of methyl methacrylate(MMA) using poly (vinyl- alcohol) (PVA) as suspension stabilizer and benzoyl peroxide(BPO) as initiator was carried out with various polymerization variables. Particle size, distribution, exothermic peak according to the polymerization condition were observed. Particle size of 5~80㎛ was prepared via homogenized suspension polymerization. Particle size was influenced by the concentration of suspension stabilizer and homogenizer speeds. The average particle diameter decreased with PVA concentration and homogenizer speeds, and increased with BPO concentration. Exothermic peak was also influenced by the stirring speed, concentration of suspension stabilizer and initiator.

본 연구는 김치가 노화와 직접적인 관련이 있는 유리기 생성 및 항산화 효소활성에 미치는 영향을 살펴보기 위하여 배추김치, 배추갓김치 그리고 갓김치를 식이중량의 5% 첨가하여 실험식이를 제조하여 이를 노화촉진쥐인 SAMP8에게 1년간 섭취시켰다. 총유리기, OH radical, H_2O_2농도 그리고 TBARS 농도 모두 가령에 따라 증가하였으며, 김치섭취시 유의적으로 감소되었다(p<0.05), 김치군에 있어서 생성된 유리기를 제거하기 위해 항산화계 효소인 SOD, catalase, GSH-px 그리고 GSH/GSSG는 모든 김치군에서 유의적으로 증가 하였다(P<0.05). 따라서 김치섭취는 먼저 가령에 의해 생성되는 유리기의 생성은 억제시키면서, 둘째 이를 제거하기 위한 항산화계 효소 활성은 더욱 활성화시키므로써 항노화 기능을 발휘한다고 생각된다. 김치종류 중에서는 배추갓김치와 갓김치가 배추김치보다 유리기 생성을 억제하고, 항산화계 활성을 증진시킨 것으로 보아 이들의 항노화 효과가 클것으로 생각된다. This study was performed to investigate the effect of kimchi intake on antiaging characteristics in the brain of senescence-accelerated mouse (SAM) in terms of free radical production and anti-oxidative enzymes. Two hundreds twenty SAM (20 mice) were divided into four groups and fed kimchi diet for 12 months. Experimental groups were kimchi free AIN-76 diet (control) group, Korean cabbage kimchi diet (KCK)group, 30% mustard leaf added Korean cabbage kimchi diet (MKCK) group, and mustard leaf kimchi diet (MLK) group. Concentrations of total free radical, OH radical and H_2O_2 of control group increased up to 123%, 262% and 174% of initial value (p<0.05) after one year. Increase in free radical production in kimchi groups due to aging was decreased by kimchi feeding. Among kimchi groups. MKCK and MLK groups showed greater inhibiting effect against free radical production than KCK. The concentration of TBARS in the bruin of control group also significantly increased up to 362% of initial value as aged (p<0.05) and production of TBARS in kimchi groups were decreased. When the activities of Cu, Zn-SOD, Mn-SOD, GSH-px and catalase of kimchi groups were compared to those of control at the same experimental period, anti-oxidative enzyme activities of kimchi groups were lower than those of control (p<0.05). But GSH/GSSG in kimchi groups were higher compared to control. In conclusion, decrease in free radical production and increase in anti-oxidative enzyme activities were observed from kimchi groups suggesting that kimchi might have important role on retarding aging. Among kimchi variety tested in this experiment, MKCK and MLK seem to have greater effect on inhibiting free radical production and increasing anti-oxidative enzyme activities than KCK.

Recently, blood pressure(BP) starts to increase in close relationship to development of persistent microalbuminuria in diabetes. Thus, author studied 24-hour BP changes in diabetics compared to the those in nondiabetics and the changes of urinary albumin excretion (UAE) according to 24-hour BP changes in diabetics with microalbuminuria. Twenty-four-hour ambulatory blood pressure monitoring(ABPPM) was performed in 38 NIDDM patients(18 normotensives and 20 hypertensives) and in 37 control subjects without diabetes(18 normotensives and 19 hypertensives) . Also 24-hour ABPM was performed in 38 diabetics (20 microalbuminurit and 18 normoalbuminuric). The analysis of individual recordings allowed us to detect an impaired circadian pattern(the disappearance of the nocturnal BP decrease or a paradoxical BP increase) in 30% of the normotensive and 31% of the hypertensive diabetics. Twenty-four-hour ABPM(night systolic/diastolic ±SD mmHg) was significantly higher in microabluminuric(124.2 ±11.4/75.1±8.2 mmHg) than in normoalbuminuric subject, (114.0±7.6/64.6±6.6 mmHg, p<0.05). This study suggests that not only awaking BP but also especially day-night minimum SBP decrease are highly responsible for the renal impairment in NIDDM patients, unrelation to hypertension. Thus. ABPM reflects the association between UAE and blood pressure in diabetics more precisely than clinical measurements. and a significant correlation exists between rate of increase in Urinary albumin excretion and blood pressure in diabetics.

This research was carried out basic study to effective manage and develop washing-separator system for plastics in hospital wastes. The results are as follows : In 1995, the generation rate of plastics in hospital waste was 6,666ton in total amount of 11,195ton. Most of syringe was PP and the composition of drainage set was PP, PVC and ABS. Therefore, separation of syringe is better than that of drainage set. Pathoganic microbes in syringe was positive before sterilization process, but became negative after that process, Pollution of syringe-washing water was increased as washing times increased and optimum washing to obtain good pellet was 6 times. Separation efficiency differed with content of injected rubber in the manufactory process of syringe makers. Remaining rubber in pellet was completely removed by the final separator developed during the this project, so we obtained good PP pellet.

This study was attempted to investigate the dissolution rate and the bioavailability of commercially available rifampicin preparations after oral administration in nine normal volunteers. Cross-over design was used for the analysis. The dissolution test was conducted in artificial gastric juice and artificial intestinal juice using basket method with four rifampicin preparations (A, B, C, and D) which were pharmaceutically equivalent. The results were as follows; The dissolution rate was higher in the order of A>C>B>D in artificial gastric juice, and A>B>C>D in artificial intestinal juice. Area under the blood concentration time curve (AUC) was larger in order of A>C>B>D. Relative bioavailability(%) of rifampicin preparations were 93.6% for B, 97% for C, 84.4% for D preparation compared with standard A preparation. Peak blood concentration (Cmax) was higer in order of A>B>C>D. Peak time (Tmax) was larger in order of D>C>A>B. Absorption rate constant (Ka) was larger in order of B>A>D>C. there was little difference in elimination rate constant and biological half-life. The correlation of the dissolution rate in artificial gastric juice and area under the blood concentration time curve as well as correlation of the dissolution rate in artifical intestinal juice and peak time showed significant linear relationship. From the result of the this experiments, it can be concluded that for the choice of preparations, bioavailability must be performed in man because the bioavailability of rifampicin preparations showed big differences among commercial preparations which were abvertised as pharmaceutically equivalent, and that the bioavailability of rifampicin preparations in man partially could be predicted from the results of dissolution rate.

이중컨버터방식의 직류전원공급장치는 4상한 운전이 필요한 직류모터, 직류쵸파, PWM인버터등의 대용량 전력변환장치의 직류전원으로 주로 사용된다. 그러나 순환전류를 제어하는 이중컨터방식의 직류전원공급장치에서는 위상제어와 P와 N 두 컨버터 사이에 흐르는 순환전류에 의하여 교류입력측에 무효전력을 발생시키는 단점이 있다. 최근 이중컨버터방식의 순환전류제어에 관한 논문이 몇편 발표된 일이 있다. 본 논문에서는 이 순환전류제어방식을 이용하여 교류입력측 역율을 1로 보상할 수 있는 방안을 제시하였으며 이방안의 가능성을 컴퓨터 시뮤레이션과 실험을 통하여 확인하다.
