Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

Objective: To evaluate the effects of bee venom acupuncture(BVA) on the rehabilitation and quality of life in rheumatoid arthritis(RA) patients Methods: Patients with RA were treated with the BVA therapy twice a week for 3 months. Tender joint counts, swollen joint counts, morning stiffness, Erythrocyte Sedimentation Rate(ESR), C-reactive protein(CRP), patient global assessment, physician global assessment, Korean health assessment questionnaire(KHAQ) were estimated and analyzed before and after BVA therapy. Results: Tender joint counts, swollen joint counts, morning stiffness showed significant decrease after BVA therapy. But, as acute inflammatory reactants, ESR showed no significant difference and CRP showed significant increase after BVA therapy. Patient global assessment physician global assessment, and KHAQ index showed significant improvement after BVA therapy. Conclusions: BVA therapy can improve rehabilitation and health-related quality of life RA patients as well as clinical symptom and signs. Further study is required in more population with large scale including acute inflammatory reaction of BVA therapy.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

In this study, we estimate the multi-service cost function of Korea Telecom in order to characterize the cost structure of the telecommunication industry in Korea. By examining the cost function of Korea Telecom, we show that telecommunication costs of Korea Telecom are subadditive. Therefore, we conclude that a natural monopoly exists in the telecommunication industry in Korea.

Liquid phase adsorption equilibria of amines in aqueous solution onto high silica zeolite pellets(HSZ) experimentally determined by use of a batch bottle technique at 298K. The data for HSZ / amines system was fit to 4 isotherm equations to determine an optimum equation. The best equation for the amine adsorption isotherms onto HSZ is the Freundlich isotherm. The products k·n of the Freundlich constant increase with the boiling point T_B, molecular volume V_m and dissociation constant pK_a of amines.

Adsorption Equilibria and Kinetics of collidine in a aqueous solution onto the synthetic resin adsorbent were carried out in a fixed bed absorber at 278, 288, 298 anti 308K for various concentration ranges respectively. The effective intraparticle diffusivity, D_(e), based on the concentration difference in the liquid phase, was determined by comparing experimental and theoretical uptake curves. The ratio of the effective diffusivity to moleculer diffusivity, D_(e)´/DAB were independent of the amount adsorbed and temperature for synthetic resin/collidine system. The result supported the concept that migrated of inter-microparticle gaps predominates over effective intraparticle mass transfer within synthetic porous adsorbent. Amount adsorbed q_(e) was correlated Q_(st) = 15.35 + [(-4.14) - q_(e)] and E_(a) = 6.28 + [(-1.671 q_(e)] with heat of adsorption(Q_(st)) and activation energy(E_(a)).

The heat transfer mechanism initiating the friction welding is examined and a transient three dimensional heat conduction model for the welding of two dissimilar cylindrical metal bars is investigated. The cylindrical metal bars are made of materials made of A2024 and SM45C. Numerical simulations of heat flow are performed using the finite volume method. Respectively, Commercial FLUENT code is used in the heat flow simulation and maximum temperature and distribution of temperature are calculated. Temperature of friction welded joining face is compared with the temperature distribution measured by experiment and numerical simulation. The maximum temperature of friction welded joining face is lower than melting point of A2024-T6 aluminum alloy using insert metal. The temperature distribution of friction welded joining face with insert metal is more uniform than that of without insert metal

The effect of the damped goose-neck tool upon the dynamic stability of machine tool was investigated. The dynamic stability of machine tool is directly related to the chatter in the metal cutting process. By the test of the dynamic characteristics for the damped goose-neck tool, theoretical approach of dynamic stability of machine tool is identified. It's results are compared with the results of actual cutting test. And the dynamic stability of machine tool is improved by the higher elasticity and the increase of damping coefficient for the damped goose-neck tool.

The authors studied on the curicullum between Korea and Japan in the deaprtments of horiculture, food technology and veterinary. The results are as follows. 1. In the department of horticulture, professional education period was 3 years in Korea while 2 or 2.5 years in Japan. These results were compared among 3 colleges of Korea and Japan. Credits for graduation was 48-52% for propessional education with submajoring subjects and 45% when majoring subject in Korea, but 54-61% in Japan. Credits for required subjects were 17-29% among credits for graduation in Korea while 28-29% in Japan. 2. Cultural education period is almost 1 year in Korea, but different in Japan. Credits for graduation are as follows; Cultural education is 36-37%, majoring fields 15% and the others 12-13% in Korea while 43-46% for cultural education, 54-57% for majoring field in Japan. Differences were shown among 3 colleges dealt with the department of food technology by locational characteristics in Japan. 3. In the department of Veterinary, collage curicullums were not fixed for the students because of transitional period. Required subjects among 4 colleges were shown as the same tendency in Korea.
