Objective : This study is performed to evaluate the clinical effect of acupuncture to acu-points in the normal side by means of amperage measured from chong points. Methods : Among the outpatients with ankle sprain who visited to Department of Acupuncture & Maxibustion, Jaseng oriental medicine hospital from 21, December 2000 to 10, February 2001, we selected 11 persons who showed normal finding in the X-ray. They were divided into two groups. One group was treated with acupuncture to acu-points in the painful side and the other was treated with acupuncture to acu-points in the normal side. Before and after acupuncture, we measured the amperage from their chong points. We selected 10 persons who we thought they were healthy as a control group. We also measured the amperage from their chong points. Results : Between the control and the ankle sprain group, there were significant differences of differences between the amperages of Rt. chong point and Lt. thong point of the same name. Between the group treated with acupuncture to acu-points in the painful side and the group treated with acupuncture to acu-points in the normal side, there were no significant differences of differences between the amperages of Rt. chong point and Lt. chong point of the same name. Conclusion : This result indicated that the acupuncture to acu-points in the painful side was not less effective than the acupuncture to acu-points in the normal side, and so the more study is needed continuously.

This paper presents a new method for generating smooth free-form surface by local correction. B-spline surface is used for its convenience of local correction, and the direction of surface correction is fixed to the average-surface-normal direction. The surface to be corrected is approximated into a uniform cubic B-spline surface. Then, the smoothness (curvature arrows, iso-parametric lines) of the approximated surface is displayed with B-spline control points. When a control point near the region that needs correction is selected, a new point 1 mm higher than the original control point in the direction of the average surface normal is displayed. And the surface is corrected by giving the amount of control point movement interactively. Since the direction of correction is given by the program and the amount of correction is selected by the user, the method is called semiautomatic. sufficiently smooth surface can be obtained by this method. Examples are given to illustrate the method.

There is a acupuncture method which make a difference according to the four seasons, according to body region or depth in skin. We call it Acupuncture follow the four seasons(四時刺法). In several chapters of Huangdineijing(黃帝內經) introduced Acupuncture follow the four seasons. Acupuncture follow the four seasons has two kinds of acupuncture method that is to acupuncture at body region and to acupuncture at five Su points(五兪穴). To use five Su points(五兪穴) according to Yongchu(靈樞) disagree with Nanjing(難經). In Yongchu(靈樞), the five phases property disagree with five Su points(五兪穴), but in Nanjing(難經) the five phases property agree with five Su points(五兪穴). Even if we can acupuncture the same point, there will be the different effect according as what is the purpose of doing acupuncture, and when we do acupuncture. That is to say, we can use apucupuncture for the purpose of prevention in Yongchu(靈樞), and for the purpose of healing the disease in Nanjing(難經). Therefore, because we select the point on the base of meridian Kis origin which spring out, we have to acupuncture Chong point(井穴) in winter according to Yongchu(靈樞). Because we select the point on the base of meridian Kis origin which flowing, we have to acupuncture Chong point(井穴) in spring according to Nanjing(難經). And in the base of five phases' property, the purpose of selecting five Su points(五兪穴) is the prevention according to Yongchu(靈樞), and the healing according to Nanjing(難經). So even though we acupuncture the exactly same Chong point(井穴), we can expect the effect that acupuncture method supply Ki for liver in winter. and the effect that it extract pathogenic Ki(邪氣) from the liver in spring.

In this paper, a hierarchical fuzzy controller is proposed for the stabilization control of the inverted pendulum system. The design of controller for that system is difficult because of its complicated nonlinear mathematical model with unknown parameters. Conventional fuzzy control strategy based only on dynamics of pendulum made have failed to stabilize. However, proposed control strategies are to swing pendulum from natural stable up equilibrium point to an unstable equilibrium point and are to transport a cart from an arbitrary position toward a center of rail. Thus, the proposed fuzzy stabilization controller have a hierarchical fuzzy inference structure; that is, the lower level is for inference interface for the virtual equilibrium point and the higher level one for the position control of cart according to the firstly inferred virtual equilibrium point.

The objective of this study is to consider the disputed point of housing problem appeared in Chosun Dynasty Chronicles and to consider the change of housing problem appeared in Chronicles according to the times. The results are: Housing affairs problem appeared steadily until king Se-chong and increased sporadically under the reign of king Sung-chong, Chung-chong. General housing hardly appeared in the early of Chosun. And it appeared sometimes in the late of Chosun. Palace problem increased gradually from the early of Chosun. And in the times of king Yonsangun it appeared most highly. Later it decreased gradually, but in the times of king Kwanghaegun it increased suddenly. And it hardly appeared in the late of Chosun. National disaster problem appeared a little in the early of Chosun but increased gradually in the middle and late of Chosun.

Objectives : This study was performed to develop a standard instrument of Pattern Identification for jing ji and zheng chong. Methods : The advisor committee on this study was organized by 15 neuropsychiatry professors of oriental medical colleges. The items and structure of the instrument were based on review of published literature. We took consultation 2 times from the advisor committee and we also took additional advices by e-mail. Results : 1. We divided the symptoms and signs of jing ji and zheng chong into 9 pattern identification. - heart deficiency with timidity(心膽虛怯), heart qi deficiency(心氣虛), heart blood deficiency(心血虛), heart yang inactivity(心陽不振), heart blood stasis(心血瘀阻), phlegm turbidity obstructing(痰濁阻滯), yin deficiency with effulgent fire(陰虛火旺), water qi intimidating the heart(水氣凌心), dual deficiency of the heart and spleen(心脾兩虛). 2. We got the mean weights that reflect standard deviation to each symptom of 9 pattern identification which had been scored on a 100-point scale. 3. We made out the Korean instrument of the pattern identification for jing ji and zheng chong. It was composed of 17 questions in question-and-answer form. Conclusions : Instrument of Pattern Identification for jing ji and zheng chong was developed through experts' disscussion. If the validity and reliability of this instrument is confirmed through additional clinical trial, the instrument of pattern identification for jing ji and zheng chong is expected to be applied to the subsequent research.

Let K be an algebraically closed field of characteristic 0 and let f be a non-fibered planar quadratic polynomial map of topological degree 2 defined over K. We assume further that the meromorphic extension of f on the projective plane has the unique indeterminacy point. We define the critical pod of f where f sends a critical point to another critical point. By observing the behavior of f at the critical pod, we can determine a good conjugate of f which shows its statue in GIT sense.

These studies were designed to determine the effect of hydroalcoholic gel system (lower alkanol concentration: 40-60%) compared to general hydrogel system (lower alkanol concentration: 10-35%) on transdermal delivery of piroxicam and its anti-inflammatory activity. Piroxicam was incorporated into a hydroalcoholic gel and a hydrogel containing polymers, solvents, and cosolvents. The pH of gel was about 6.3-7.3 and the solvent mixtures were composed of water and various concentrations of ethanol (35, 40, 50, and 60%). For the in vitro study, the skin permeation of piroxicam from the gel formulations was investigated using Franz modified diffusion cells fitted with hairless mouse skin. For the in vivo study, the anti-inflammatory activity of hydroalcoholic gel was compared to other commercial products (piroxicam hydrogel and ketoprofen hydrogel) in rat and human. The anti-inflammatory activity was determined using carrageenan induced foot edema model in rat. For the clinical study, it was evaluated from determining efficacy and acceptability with 98 patients suffering from musculoskeletal pain. A novel piroxicam hydroalcoholic gel was successfully formulated in the range of 40-50% of ethanol as solvent, more than 10% of propylene glycol, 5% of $Transcutol^{\circledR}$ and 1 % of benzyl alcohol. The skin permeation of piroxicam using hydroalcoholic gel system was greater than that of general hydrogel system $(flux\;:\;139.1-148.2\;{\mu}g/cm^2/hr\;vs.43.0-84.5 {\mu}g/cm^2/hr)$ in vitro. In carrageenan-induced edema model, the anti-inflammatory activity of hydroalcoholic gel was better than that of piroxicam hydrogel for edema inhibition (75.1 % vs. 62.9%, p
