Objective : This study was done for reporting the effect of $Sa-Am$ acupuncture bladder reinforcing method to $Ryodoraku$ on the patients with chronic low back pain Methods : We investigated 49 cases of patients with chronic low back pain, and devided patients into two groups : We treated one group by needling with $Sa-Am$ acupuncture bladder reinforcing method, and did the other group by needling without $Sa-Am$ acupuncture bladder reinforcing method. And we analyzed the $Ryodoraku$ score (F4). Results : 1. In $Sa-Am$ acupuncture bladder reinforcing method group and non-$Sa-Am$ acupuncture bladder reinforcing method group, compared with baseline, at final, $Ryodoraku$ score (F4) was significantly increased. 2. At final, $Sa-Am$ acupuncture bladder reinforcing method group showed significant increase on $Ryodoraku$ score (F4) score compared with non-$Sa-Am$ acupuncture bladder reinforcing method group. Conclusions : $Sa-Am$ acupuncture bladder reinforcing method showed significant improvement in $Ryodoraku$ score (F4) on chronic low back pain.

It is very important to understand objectively the Qi variation induced by the reinforcing-reducing manipulation method in the therapy of acupuncture. The Qi variation in the meridian treated by O-Haeng Reinforcing-Reducing Manipulation Acupuncture Method and the recovery of Five Phase deviation were measured by choosing complex acupoints. By using O-Haeng Reinforcing-Reducing Manipulation Acupuncture Method, we increased or decreased the Qi of the phase which caused the unbalance state. We observed whether the Qi of the treated meridian can be increased or not and if the state of unbaIance can be recovered. To achieve the effect of reinforcing-reducing, we need a correct choice of treating method and a selection of a proper meridian in advance. We discovered that the effects of reinforcing-reducing by each manipulation method could be superposed each other, when two counteracting O-Haeng Reinforcing-Reducing Manipulation Acupuncture Method were treated at the left and the right side of human body. We found that the Qi variation of the traeted meridian, which was induced by O-Haeng Reinforcing-Reducing Manipulation Acupuncture Method, is lineary proportioned to the reduction of Five Phase deviation.

Objective : To establish a standard for discriminating between deficiency syndrome and excess syndrome and selecting reinforcing or reducing method. Methods :Deficiency syndrome and excess syndrome were divided into excess of pathogenic factor with sufficiency of vital energy syndrome, weakness of pathogenic factor with deficiency of vital energy syndrome and excess of pathogenic factor with deficiency of vital energy syndrome. Documentary survey was done for each case. Results : Excess of pathogenic factor with sufficiency of vital energy syndrome is an excess syndrome and a reducing method must be used. Weakness of pathogenic factor with deficiency of vital energy syndrome is a deficiency syndrome and a reinforcing method must be used. Excess of pathogenic factor with deficiency of vital energy syndrome is related to deficiency syndrome and a reinforcing method must mainly be used. Conclusions :Deficiency or sufficiency of vital energy is the standard for discriminating between deficiency syndrome and excess syndrome and selecting a reinforcing or reducing method.

본 연구에서는 단부 RC 중앙보 S조 혼합보에 대해 RC부 주근의 정착방법(플랜지 위에 직접 용접, 스터드 볼트 용접 정착) 과 이질구조부 (SRC 부)의 보강 방법에 따른 구조적 거동 분석을 고찰하였다. 이질구조부 보강방법으로는 무보강, 수직전단보강근 보강[D10-@50], 경사보강(X자형 보강), 수평보강1[웨브보강(0.3L)], 수평보강2[웨브보강(0.3L)], 수직보강[플랜지보강(0.3L)]과 같은 보강방법을 주요변수로 하여 구조적 특성을 상호 비교 분석하였다. 그 결과 보 주근의 정착방법에 따른 연성능력 및 내력 등과 같은 구조적 특성에는 큰 차이가 없었으며, 혼합구조보의 구조적 특성을 극대화시키기 위해서는 이질구조부를 수직보강한 경우와 2열 수평으로 보강한 방법이 가장 효과적인 것으로 나타났다.

This paper presents a nonlinear finite element analysis procedure for the seismic performance assessment of reinforced concrete bridge piers with unbonded reinforcing or prestressing bars. A computer program named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology) is used to analyze reinforced concrete structures; this program was also used in our study. Tensile, compressive and shear models of cracked concrete and models of reinforcing and prestressing steel were used account for material nonlinearity of reinforced concrete. The smeared crack approach was incorporated. To represent the interaction between unbonded reinforcing or prestressing bar and concrete, an unbonded reinforcing or prestressing bar element based on the finite element method was developed in this study. The proposed numerical method for the seismic performance assessment of reinforced concrete bridge piers with unbonded reinforcing or prestressing bars is verified by comparison of its results with reliable experimental results.

압력분사 그라우팅 네일을 이용한 사면보강공법은 천공 후 그라우트재에 압력을 가하여 그라우트재의 천공홀 충전뿐만 아니라 지반으로의 침투주입 효과를 일으켜, 전체적인 보강력 증대를 기대하는 공법이다. 이런 특성을 설계에 반영하기 위해서는 구조재료 자체에 의한 지반보강효과 뿐만 아니라 압력분사 그라우팅에 따른 지반강도의 증진효과를 정량적으로 평가하는 것이 선행되어야 하나 아직까지는 이에 대한 연구가 부족한 실정이다. 따라서 절리가 발달한 풍화암 사면을 대상으로 시험시공 및 계측을 실시하고, 얻어진 계측값을 평가하여 절리가 발달한 풍화암 사면에서의 보강특성을 확인하였다. 또한 계측값으로부터 얻은 보강특성을 설계에 적용하기 위한 역해석 기법을 제안하였으며, 제안된 역해석 기법을 통하여 암반사면에서의 압력분사 그라우팅 네일 공법의 효용성을 확인하였다.

Locating reinforcing bars, in particular to know their accurate depths and horizontal distances, is very important in radar inspection of concrete structures. By the way, it is not easy for an accurate depth and horizontal distance estimation of reinforcing bars in concrete structures by the radar test. This problem can be solved by synthetic aperture radar method. To improve the vertical and horizontal resolution of reinforcing bars in concrete, synthetic aperture radar method was examined in this study.

The reinforcing subgrade, which first introduced Korea for the highspeed subgrade construction, has the many advantages to maintain the quality of ballast track as well as to prevent the softening of subgrade by mud-pumping. It causes the subgrade soil to spout into the ballast on many lines. Therefore, the application of reinforcing subgrade will be expected to increase in the future. This paper introduces the reinforcing subgrade as a maintenance-free technology f3r the railroad operation and the method f3r the determination of reinforcing subgrade depth. The criteria on reinforcing subgrade depths of highspeed and conventional railroad were verified from the calculation results based on an elastic analysis method.

To minimize construction of nuclear facility, it is required to reduce reinforcing bar amount and solve reinforcing bar concentration and for this, it is necessary to develop appication design technology and modular of high strength reinforcing bar. Hence, KHNP reduces excessive reinforcing bar amount which can cause possibility of poor construction of concrete through design standard development and modular of nuclear facility structure using high strength reinforcing bar to raise economics and has its purpose to maintain high-level safety and durability as they are. This study is to introduce application method for the Rebar Modulation of High-Strength Reinforcing Bars to the Nuclear Power Plant Structures.

Reinforcing bar coupling method has a variety of ways including lap-splice method. However, there are problems that need to be improved in terms of constructability, economics analysis. We should be improved about the problems of the existing methods. Accordingly, this study were developed a new type of staggered grip type reinforcing bar coupling. The proposed method show the following effects than existing methods. First, this method can be reduce time through improved workability. Second, increasing safety through the slip removal. Third, improving economic efficiency by reduce the manufacturing costs.
