Objectives : To observe the effect of acupuncture and nerve block combination treatment on adhesive capsulitis patients. Metbods : 59 voluntary patients were randomly assigned to acupuncture treatment group(E group ,n=22), nerve block treatment group(W group, n=17) and acupuncture and nerve block combination treatment group(EW grouP, n=20). The E group received acupuncture treatment on LI15, TE_(14), GB_(21) and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection twice a week for 4 weeks. The EW group received the same treatment as the W group and after 5minutes of rest, successively received the treatment identical to that of E group. AU three groups were instructed to practice groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after 1, 2, 3 and 4week treatment. Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI), Range of Motion(ROM), the patient's treatment satisfaction measured by Visual Analogue Scale(VAS) and Digital Infrared Thermographic Imaging(DITI) were used as assessment tools. The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Adduction and Extension improved significantly(p<0.05). The W group showed significant improvement(p<0.05) on CSA, SPADI, VAS and DITI. As for ROM, Abduction and Extension improved significantly. The EW group showed significant improvement(p<0.05) on CSA, SPADI and VAS. As for ROM, Adduction, Abduction, Extension and Flexion improved significantly. The improvement of CSA, VAS and Abduction ROM in the EW group was significant1y(P<0.05) superior compared to the groups treated with single type of treatment. Conclusion : It is suggested that acupuncture and nerve block combination treatment for adhesive capsulitis patients is more effective than the two single treatments. Through further studies, the acupuncture and nerve block combination treatment model may be developed into East-West Collaboration Model in treating adhesive capsulitis.

남기우,박소순,안석환,도재윤,박인덕 한국비파괴검사학회 2003 한국비파괴검사학회지 Vol.23 No.2

STS316L은 인성, 연성, 부식저항성 등 우수한 기계적 성질 때문에 에너지환경설비 등 구조물에 널리 이용되고 있다. 그러나, 용접구조물은 가혹한 환경하에서 경년열화가 심각하다. 지금까지의 연구들은 주로 용접부의 피로균열진전거동에 관하여 수행되었고, 피로균열진전속도식의 재료상수와 비파괴적 평가의 상관성에 관한 연구는 거의 없었다. 본 연구는 STS316L 용접부의 피로균열진전 거동을 조사하고, 초음파 파라미터로 열화특성을 평가하고 시간-주파수 분석으로 해석을 하였다. 본 연구 결과는 용접구조물의 사용기간 중 피로수명 등을 예측하기 위한 기초 데이터로서 사용될 수 있다. STS316L had been used as the structural material for energy environmental facilities, because austenite stainless steels like 316L have superior mechanical properties of which toughness, ductility, corrosion resistant and etc. However, those welded structures are receiving severe damage due to increasing of the aged degradation. Most studies until now have been carried out against fatigue bahaviors of weldments, and were not well studied on nondestructive evaluation methods. In this study, the fatigue crack propagation behavior of STS316L weldment usually used for vessels of the nuclear power plant was investigated. Also, the degradation characterstics of 316L stainless steel weldments were evaluated by the ultrasonic parameter such as ultrasonic velocity, attenuation factor and time-frequency analysis. The results of this study can be used as a basic data for the prediction of the fatigue crack life of weldments structures without disjointing or stopping service of structures in service.

유리전이 온도를 포함하는 온도주기환경이 에폭시/카본 복합재료에 미치는 영향

남재도 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.2

항공기의 구조용 소재로 사용되는 epoxy/carbon fiber 복합재료가 메이트릭스의 Tg를 포함하는 온도주기를 경험할 때 발생하는 복합재료의 구조 및 물성변화를 실험과 모델링을 통하여 연구하였다. 복합재료의 표준경화온도인 177℃에서 2시간을 aging시킨 후 냉각시키는 반복되는 열주기 (thermal cycle)는 점진적으로 복합재료를 brittle하게 하여 결국 표면에서부터 microcrack을 유발시킨다는 것을 알 수 있었다. 이러한 열주기에 따른 microcracking현상은 메이트릭스의 degradation반응이 발생하는 effective surface area를 증가시키고 산소의 투과를 용이하게 하여 복합재료시편의 무게감소를 가속화시킨다는 것을 규명하였다. 또한 열주기는 dynamic mechanical relaxation time을 증가시킨다는 것을 확인할 수 있었는데 특히 유리전이온도 이상의 relaxation time이 점진적으로 증가하였다. 마지막으로 isothermal과 dynamic heating을 반복하는 열주기를 특정온도의 isothermal holding시간으로 전환할 수 있는 equivalent cycle time (ECT)를 제안하였는데, 이로부터 thermal cycle만이 독특하게 보여주는 손상의 가속/감속 현상을 규명할 수 있었다. Thermal cycling of high performance epoxy/carbon fiber composites was investigated in order to identify the structural changes and long-term durability of the composite laminates exposed up to the glass transition temperature. Simulating the standard cure cycle of TGDDM/DDS-based epoxy prepregs, the specimens were held at 177℃ for 2 hours in air followed by subsequent cooling and heating steps in each thermal cycle. The successive thermal cycling induced microcracking at the laminate surface subsequently resulting in accelerated weight loss of composite specimens. Thermal cycles also increased the dynamic mechanical relaxation time especially above the glass transition temperature in the rubbery state. Finally, the equivalent cycle time (ECT) was developedd by using the reaction kinetic theories, which could convert the heating/cooling/holding thermal. history to an equivalent isothermal time at a specific temperature.

항공용 복합재료 프리프레그의 점탄성 기체 투과 현상연구

남재도 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.1

Gas permeation and creep deformation of a commercial prepreg were investigated as a function of time, temperature, and consolidation pressure, identifying the viscoelastic characteristic of prepregs. Experiments using a prepreg stack demonstrated that the material exhibited a linear viscoelastic bulk deformation under vacuum/autoclave pressure and the in-plane gas flow exhibited non-Darcian flow behavior with a permeation hysteresis. This behavior was viewed and analyzed by two viscoelastic relaxation processes : (1) bulk dimensional relaxation, and (2) microscopic pore structure rearrangement. A modified standard linear solid (SLS) viscoelastic model was used to interpret the creep compliance and dynamic gas permeability utilizing two independent relaxation parameters.

As time goes up, structural capacity of members decreases in reinforced concrete structures. The deterioration of the capacity is mainly due to the corrosion of materials, poor construction and environmental pollution, etc. This deterioration is unavoidable, thus it is necessary to develop the method for repair and retrofit of structures in order to ensure structural safety of members. The purpose of this paper is to investigate the load-deflection, ultimate strength, failure mode, and energy absorption effect. For the test, the specimen size of column is 20cm×20cm×90cm reinforced with 4 number of main bars of 13mm diameter, tied bars of 6mm diameter. The test results show that the increasement of bolt and bolt tension's quantity improve the ultimate strength and energy absorption capacity.
