The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

The purpose of this study is to find whether isokinetic training has a good effect on decrease of the lower limbs muscular strngth caused by aging and find the isokinetic training Speed which has a good effect on muscular strength. The subjects of this study are 16 elderly women aged from 61 to 65. The subjects were distributed into two groups, low-speed isokinetic training program group(n=8) arid high-speed isokinetic training program group(n=8) respectively. The subjects of two groups participated in lower extremities isokinetic training program three times a week for 12 weeks. Changes of the lower limbs muscular strength after training were analyzed through repeated measures anova. Results of this study are following: 1. Change of knee extension isokinetic peak torque at the 60˚/ sec in the LS group after 12 week training was significantly different form HS groups. There was no significant difference in knee flexion peak torque among groups. 2. Change of knee extension isokinetic peak torque at the 180˚/sec in the HS group after week training was significantly different form LS groups. There was no significant difference in knee flexion peak torque among groups.

In this paper the simulation methods for fluid transmission lines are studied and realized which is necessary in design and analysis of hydraulic control systems. Bond graph concept which is based on causality between components and lumped parameter models are utilized for simulation. Various types of transmission lines are suggested and used for simulation to compare with experimental results. The simulation results obtained through making partition of transmission line show a similar tendency with experimentals.

CVM 연구에서 설문자료로부터 WTP 분포를 근사화하는 작업은 표본내에 포함된 0의 응답 때문에 문제가 발생할 수 있다. 이 때 WTP의 이중적 분포를 무시하면, 즉 연속적인 분포를 가정하면 후생치 도출에 있어 왜곡이 있을 수 있다. 본 연구는 이런 문제를 해결하기 위해 혼합모형을 제안하고 적용한다. 혼합모형은 영에서 점질량으로 이루어진 분포와 양의 연속적 분포를 혼합하는 특징을 갖고 있다. 이 경우 지불의사가 전혀 없는 확률은 모수 ρ로 표현되고, 별도로 식별가능하며, 최우추정법을 이용하면 일치추정량을 얻을 수 있다. 본 연구에서는 한려해상국립공원을 대상으로 혼합모형의 적합성에 관한 실증연구를 수행하였는데 그 결과 혼합모형의 적용이 바람직한 것으로 나타났다. Approximating a WTP distribution of the conservation for Hallyue Marine National Park is complicated by zero observations in the sample. To deal with the zero observations, a mixture model is considered to allow a point mass at zero. The model is empirically verified for the data. The conventional model and a spike model are also considered for comparison. Our results portrays the usefulness of the mixture model to analyze SBDC data with zero observations.

The author present a modified multi-loop algorithm including feedforward for controlling a 55kW step down chopper in the power supply of Maglev. The control law for the duty cycle consists of three terms. The first is the feedforward term which compensates for variations in the input voltage. The second term consists of the difference between the slowly moving inductor current and output current. The third term consists of proportional and integral terms involving the perturbation in the output voltage. This perturvation is derived by subtracting the desired output voltage from the actual output voltage. The proportional and integral action stabilizes the system and minimizes output voltage error. In order to verify the validity of the proposed multi-loop controller, simulation study was tried using Matlab simulink.

Some authors suggest that certain types of surfaces are the origin of such injuries. A few years after the first medical concerns about surfaces were voiced, publications of biomechanical measurements apperared, describing accleration, force, and impact measurement on different types of surfaces. In many sport activities, surfaces can be under very high dynamic load. This was the reason for the development of various methods for impact simulation, like the development of various methods for impact simulation, like the artificial athlete. Furthermore, it is important to collect information about the hardness of new and already existing surfaces in sport arenas. The idea on which this measuring system is based Is as follows: The stiffness of the material can be computed from the kinematics measurd at touch down of a rigid body onto a material sample. The results show the following The result for the artifical surfaces(Synpave ace) is surprising. It is known that these surfaces are much harder than synpave rebound classic, synpave spring. This finding suggests that it may be possible that the subjective impression is used as one criterion in the selection of landing(or style) strategies. The number of subjects in this experiment is too small to make statistically significant conclusions. It is shown analytically that when an object a deformable surface, the acceleration it experiences is inversely propotional to its mass. In future, it need to stress that the interaction between shoe and surface is important, and this aspect has now become well accepted. Considering biomechanical aspect in player's injury, it request Korean Standards for synthetic playing surfaces in sport like ASTM(America Society for Testing & Materials) standards of America, DIN 18035 standards of Germany, BSI standards of U.K.
