Objective The purpose of this study was to report the efficiency of Bee Venom Pharmacopunture Therapy by managering of Benign Prostatic Hyperplasia patients. Method Two patients were treated with Bee Venom Pharmacopunture and another Korean Medicine therapy for six weeks and compared with I-PSS(International Prostate Symptom Score) before and after. Results After treated with Bee Venom Pharmacopunture Therapy, 'I-PSS' values decreased significantly all the patients. Conclusions Bee Venom Pharmacopunture Therapy was shown fairly effective to Benign Prostatic Hyperplasia.

환경훼손 및 주거 과밀지역의 민원을 최소화할 목적으로 도심지 공사에서 쉴드터널공법의 적용이 날로 증대되고 있다. 쉴드터널의 주 구조체인 라이닝 세그멘트는 연속체가 아닌 이음부를 가지는 구조로 되어져 있다. 지금까지 설계실무에서는 라이닝 세그멘트의 구조해석 모델이나 설계하중 및 지반정수의 영향 등에 대한 별다른 검증 평가없이 과거의 국내 외 설계자료를 관행적으로 적용하고 있다. 본 연구에서는 국 내외에서 현재 사용하고 있는 쉴드터널의 세그멘트 해석 및 설계 모델들에 대해 이론해와 수치해의 비교를 통하여 적정성을 평가하였다. 그 결과, 사용의 편이성과 현장조건 의 적용성, 해석결과의 적용성 측면에서 전주면빔이음스프링 모델(1R-S0)을 제안하였다. 그리고, 제안된 모델을 이용하여 이음부 강성과 지반강성, 이음부 분할 분포 및 분할 개수 등에 대한 매개변수 해석을 수행하였다. 그 결과, 이음부를 갖는 라이닝 세그멘트에 발생하는 휨모멘트는 일정한 크기 이상의 지반강성에서 이음부가 없는 연속체의 라이닝 세그멘트에 발생하는 휨모멘트의 크기에 일정한 비율로 수렴함을 알 수 있었다. 또한, 이음부의 강성이 작을수록 측벽부에 비하여 천정부와 바닥부의 휨모멘트가, 수평변위에 비하여 수직변위가 이음부 분할 분포에 따라 큰 영향을 받는 것을 알 수 있었다. The shield tunneling method has been increasingly employed to minimize environmental damages and civil complaints in the populated and developed area. A lining segment, which is a main structure of the shield tunnel, consists of joints. Conventional foreign and domestic design data have been commonly used for design practices without a specific verification of structural analysis models, design load, and the effect of soil characteristics on the performance of lining segment. In this study, the suitability of existing analytic models used for the design of shield tunnel lining segment has been evaluated through a comparison between analytical and numerical solutions. Based on the evaluation of their suitability performed in the study, a full-circumferential beam jointed spring model (1R-S0) is proposed for design practices by considering user's convenience, the applicability of field conditions and the accuracy of analysis result. By using the proposed model, the parameter analysis was performed to investigate the effects of joint stiffness, ground rigidity, joint distribution and the number of joints on the behavior of lining segment. Parameters considered in the investigation have been appeared to affect the behavior of lining segment. Among those parameters, joint stiffness has been appeared to have the most significant effect on the bending moment and displacement of lining segment.

Recently, Organic EL(Electro Luminescence)is interested in Flat Panel Display (FPD) department of new generation. This paper describes a image processing algorithm for the scratch detecting for ITO coated glass. We use the logical level thresholding method for binarization of gray-scaled glass image. This method is useful to the algorithm for detecting scratch of ITO coated glass automatically without need of any prior information of manual fine tuning of parameters.

This study has been started for the development of a refined live load distribution formula that has safety and precision toward I type prestressed concrete girder bridge. This type of bridge is mainly applied to short span bridges that are 25~40m in length. Based on various structure analysis models that are currently being applied as preceding studies for the development of live load distribution method, an analysis of flexural stiffness ratio for barrier and diaphragm has been performed. As the result of parametric analysis for the changes in flexural stiffness ratio, the effect of barrier on load distribution showed as insignificant in all structural analysis models while analyzing the deflection distribution. Also, the deflection distribution of the models with stiffness of 25% in which the diaphragm eccentricity is accounted for as same as the models with stiffness of 100% in which the diaphragm eccentricity is unaccounted for. This results are verified through the comparison with a experimental data.

In this paper, the direct and indirect neural adaptive controller are combined based on the Lyapunov synthesis approach. The proposed adaptive controller is constructed from RBF neural network and a set of fuzzy IF-THEN rules. And the weighting parameters are adjusted on-line according to some adaptation law for the purpose of controlling the plant to track a given trajectory. In this scheme, fuzzy IF-THEN rules are used to decide the combined weighting factor. It is shown that all the signals in the closed-loop system are uniformly bounded under mild assumptions. The effectiveness of the proposed control scheme is demonstrated through the control of one-link rigid robotics manipulator.
