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.

Ni/Y-zeolite catalysts were prepared by conventional ion exchange, and was investigated the nickel metal distribution in Y-zeolite by carrying out the TPR/TPO, TEM, FMR, and XRD experiments. The experiments have shown the existence of a bidispersion of nickel metal particles ; i.e., small particles were restricted inside the zeolite pores, while larger ones were formed outside the zeolite crystal.

This study has demonstrated the efficacy of arthrocentesis of upper temporomadibular joint (TMJ) compartment in cases of severe pain and limited maximum mouth opening (MMO) in traumatic hemarthrosis of TMJ. Thirteen patients complaining of severe pain and limited MMO were treated by irrigation of the upper compartment of the affected TMJ with lactated Ringers solution. This treatment was found to be effective in reestablishing normal mouth opening and relieving pain within I week in postoperative. It is suggested that arthrocentesis simple, less invasive, inexpensive, and highly efficient procedure, which can be performed under local anesthesia, is used in traumatic hemarthrosis cases with severe pain and limited MMO.

Performing genioplasty for greater stability of the changed chin position, incision, dissection, osteotomy design and fixation are important technical considerations. Basically, wire osteosynthesis method has been used in genioplasty, but plate/screw osteosynthesis has been introduced in rigid fixation. The purpose of this study is that comparison of stability between wire and plate/screw osteosynthesis in genioplasty. In this study, the genioplasty groups were divided into three groups ; advanced genioplasty group, reduction genioplasty group, advanced with reduction genioplasty group. In wire osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 12patients who had advanced with reduction genioplasty. In plate/screw osteosynthesis groups, there were 15patients who had advanced genioplasty, 13patients who had reduction genioplasty, and 13patients who had advnaced with reduction genioplasty. Lateral cephalograms ; pre- and postoperatively, postoperatively 1months, and at the latest follow-up(>6months); were analyzed by linear measurement to evaluate changes in position(hard tissue B, Pogonion point) and compare relapse between both groups.

As for endurance performance which results in exhaustion of muscle ammonia, plasma ammonia and brain ammonia of the way of restraining or decreasing concentration of ammonia which cause central nervous tissues to be exhausted activity, directly-opposed results to the effect of OKG administration could be noticed and the following conclusions could be obtained on the basis of the outcome from the observation of delaying the exhaustion of central nervous tissues and executive capability for endurance exercise. 1. OKG administration before endurance performance decreased the concentration of muscle ammonia at the time of 30 minutes after exercise and exhaustion through the whole exercise(p<.05). 2. OKG administration before endurance performance decreased the concentration of plasma ammonia at the time of 30 minutes after exercise and exhaustion through the whole exercise(p<.05). 3. OKG administration before endurance performance decreased the concentration of brain ammonia at the time of 30 minutes after exercise and exhaustion through the whole exercise(p<.05). 4. OKG administration before endurance performance increased the duration period of endurance performance by 25 minutes at large(p<.05). The restraint or decrease of the main causes of central nervous tissues which result from endurance performance due to OKG administration before endurance performance could be noticed by this research on animals, and it could be said that OKG administration before endurance performance increase the executive capacity of endurance performance, and since there were more or less insufficient parts to minimize important fallacies which can happen at the experiment on animals, it is more considered that the result of the research should attain to much reliable result through further various researches afterward and the same result are obtained than that it is applied to human being directly to improve techniques of various sports connected with endurance performance.

Since the fatigue strength of steel under the corrosive environment, corrode and fatigue at the same time, thus fatigue strength is lowered eminently by these effects. Also, the fatigue limit does not appear in artificial sea water, but appear in air. As the N? increases, the fatigue strength decreases accordingly. Therefore the fatigue designs of machinery or steel structures, which are used under the corrosive environment, must be limited life-design. The estimation of life is a very important factor. The purpose of this investigation is to obtain the saturated values of fatigue strength. We investigated the rotary bending test (cyclic rate: 0.5cpm) with smooth bar specimen of SM50B steel (JIS) in two different environments which are air and artificial sea water and compared with results concerning of the 7.5cpm under the same condition. The following results are obtained. 1) The fatigue life decreases by about 46% in artificial sea water in comparison with that in air. 2) S-N curves of 7.5cpm and 0.5cpm are same, so that we conclude, at the 0.5cpm is the saturated value of fatigue strength. 3) The ratio of fatigue strength decreases minutely by the number of cycle to failure increases. 4) In artificial sea water, the corroded oxidation occured in the location where the stress was concentrated.

[Cp₂Ti(Ⅲ)(1-benzoylacetonato)과 조촉매인 알킬알루미늄화합물로 구성된 촉매계를 이용하여 스티렌을 중합하였으며, 생성된 고분자는 ^(13)C NMR 스펙트럼 연구결과 atatic-폴리스티렌이었다. 고분자 반응에 영향을 주는 조건인 주촉매의 농도, 조촉매인 DEAC의 농도와 주촉매의 농도 비율, 반응시간 및 반응온도에 따른 연구를 수행하였다. 고분자 반응은 반응온도에 영향을 받지 않으며 폴리스티렌으로의 전환 비율이 가장 큰 경우는 DEAC의 농도와 주촉매의 농도 비율이 30인 경우이며 고분자 반응은 6시간만에 완료된다. 연구한 조건에서 생성된 폴리스티렌의 분자량은 2,200 - 3,200이었으며, 중합온도가 증가하면 분자량은 감소하고 분산도는 증가하며, 티타늄 촉매에 대한 조촉매의 몰 비율을 증가시키면 분자량과 분산도가 증가하는 경향을 보였다. Polystyrene was prepared in the presence of a catalyst composed of [Cp₂Ti(Ⅲ)( 1-benzoylacetonato)] and alkylaluminum as cocatalyst. The resultant polymer is atatic-polystyrene judging by ^(13)C NMR spectra. Influences of various polpmerizations, e.g., [Ti], [DEACI/"Til, time and temperature were studied. It was found that polymerization reaction is not dependent on the reaction temperature, and the highest conversion of styrene to polystyrene can be obtained when the molar ratio of [DEAC] to [Ti] is 30. The polymerization reaction is almost finished in 6 hours. The molecular weight of the polystyrene ranged from 2,200 to 3,200 and was decreased and the molecular weight distribution was increased with increasing the reaction temperature. The higher the molar ratio of DEAC to titanium catalyst was used, the higher was the molecular weight and the molecular weight distribution.
