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.

This study was to investigate structural behavior of composite structure beams composed of end-RC. center-Steel according to respective reinforcing method for connection zone composed of different materials (SRC) while attaching main bars on steel-flange by welding. The main reinforcing methods are as follows ; non-reinforcing, vertical shear reinforcing (type-stirrup), inclined reinforcing(type-x), horizontal reinforcing(type-web, 0.3L), double horizontal reinforcing (type-web, 0.3L), vertical reinforcing (type-flange, 0.3L). Consequently, It showed little difference in structural properties like ductility and strength according to the attaching method of main bars. For Maximizing the structural properties of composite beam, the most effective methods were vertical reinforcing one and double horizontal reinforcing one.

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.

The slope reinforcing method utilized in this paper reinforces the ground overall by means of filling borehole as well as permeating grout material into ground by injecting it through the grouting pipe. In order to reflect these characteristics to design, not only the ground reinforcing effect by the structural material itself but also the ground strength improvement effect by the grouting injection must be quantitively evaluated. But precedent research of it has been insufficient. Therefore, the slope reinforcing method was applied to the weathered rockmass slope situated in the highway in order to analyze reinforcing effect and the instrumentation of slope was performed. Through analysis of this field test, the slope reinforcing method was proved to be effective and back analysis method based on instrumentation values of slope was proposed to apply to reinforcing design. In this paper, the effectiveness of reinforcing method was certified through proposed back analysis.

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.
