본고는 옥소 권섭의 문집인 "옥소고"에 실린 몽화와 관련한 자료를 검토함으로써 선행연구의 잘못을 바로잡고 몽화의 제작과 관련된 제반 문제를 이해하는 데에 목적을 두었다. 그 내용을 요약하면 다음과 같다. 먼저 몽화의 현황을 살펴보면 몽화는 옥소의 필사본 문집인 "옥소고" 중 제천본에 56점, 문경본에 47점이 실려 있다. 그리고 몽화에 기록된 꿈은 옥소의 나이 50대 후반부터 70대 사이에 집중되어 있다. 그리고 몽화는 평양 출신의 화가인 조세걸과 권섭의 아우인 권영, 권섭의 손자인 권신응 등 최소 3인 이상이 그린 것으로 보인다. 이중 조세걸은 1695년에 해도별서<(海島別墅)>를 그렸으며, 권영은 1696년의 꿈인 백옥계<(白玉溪)>를 그리는 것으로부터 시작하여 1743년까지 계속하여 몽화를 그렸다. 그리고 권신응은 1743년, 16세의 나이에 몽화를 그리기 시작하였다. 기승첩(奇勝帖), 혹은 몽화첩의 제작은 다음과 같은 방식으로 이루어졌다. 먼저 꿈을 꾼 뒤에는 옥소가 그 꿈을 글이나 시로 기록한다. 그리고 이를 가지고 꿈속에서 같이 놀았던 사람에게 화답시를 얻는다. 마지막으로 화가를 시켜 꿈 속 광경을 그리게 한 뒤, 글과 그림을 엮어 그림첩으로 만든다.

The purpose of this study was to analyze bradykinesia of toe tapping movement in patients with Parkinson's disease (PD) as compared to those of normal subjects. 39 PD patients (age: $65.5{\pm}11.2$ yrs, H&Y stage:$2.3{\pm}0.5$), 14 eldelry subjects with comparable mean age ($65.0{\pm}3.9$ yrs) and 17 healthy young subjects ($24.1{\pm}2.1$ yrs) participated in this study. Angular velocity during repetitive toe tapping movement was measured in both feet using a gyro sensor system. Suggested quantitative measures of bradykinesia were root-mean-squared (RMS) angular velocity, RMS angle, peak power and total power which were derived from the angular velocity signal. ANOVA showed that all measures were significantly different among three groups (p<0.001). Subsequent post-hoc test revealed that all measures in PD patients were significantly smaller than in healthy elderly and healthy young subjects (p<0.02). All measures were significantly correlated with UPDRS scores(r=-0.689~-0.825). These results suggest that the developed system can be used as quantitative measures of the lower limb bradykinesia in PD patients.

Bifurcation intability modes of axially compressed circular cylindrical shell are investigated in the limit of zero thickness (i.e., h (thickness) ${\rightarrow}$ 0) analytically, adopting the general stability theory developed by Triantafyllidis and Kwon (1987) and Kwon (1992). The primary state of the shell is obtained in a closed form using the asymptotic technique, and then the straight-forward bifurcation analysis is followed according to the general stability theory to obtain the bifurcation modes in the limit of zero thickness in a full analytical manner. Hence, the closed form bifurcation solution is obtained. Finally, the result is compared with the classical one.

Multidrug resistance (MDR) has been a major problem in cancer chemotherapy. To overcome this problem, we prepared minor ginsenosides stereoselectively from ginseng saponins and searched for a ginseng component which is effective for inhibition of MDR. MDR inhibition activity was determined by measuring cytotoxicity to MDR cells using multidrug resistant human fibrocarcinoma KB V20C, which is resistant to 20 nM vincristine and expresses high level of mdr1 gene. Of several ginseng components, 20(S)-ginsenoside Rg_3$, a red ginseng saponin, was found to have the most potent inhibitory activity on MDR and it's concentration capable of inhibiting 50% growth was $82\muM$.
