Objectives : This study is designed to investigate the association between Samcho-gyeong(TE) and the lower branch of Meridian system. Methods : The base of the study was established by searching for the historic conception of Samcho. Thereafter the meaning of lower correlation was considered and the property of lower part of Samcho Meridian system studied. Results : Samcho is a kind of Yug-Bu(Six hollow viscera, 六腑). It is a functional internal organ, which has been continuously controversial in history. It covers wide range of the internal organs and plays various kinds of roles. Samcho and Simpo lack in interrelation of obverse and reverse. The conception of Sanghap(Upper correlation, 上合) in Naegyeong supplements the deficiency. To establish the conception of Sanghap between Yug-Bu and Hand meridians, there should be established the conception of Hahap(Lower correlation, 下合) between Yug-Bu and foot meridians for treating lower parts. The existence of Hahaphyeol(Lower confluent points, 下合穴) reveals that there were a lot of limits in treating JungHa-cho(Middle and Lower energizers, 中下焦) diseases only with the acupoints of the Hand meridians. Jogsamcho(Triple energizer of foot, 足三焦) meridian written in Taeso(太素), corresponds to the lower leg, and it is believed that it engages in treating diseases in the trunk of the body and Hacho(Lower energizer, 下焦). Conclusions : Therefore, it is believed that the lower part of meridian of Samcho can deal with the symptoms of lower back pain, leg pain, bladder disease, and so on. This study is meaningful in that it expands the range of treatment in acupoints of the regular meridians.

The present experiment was carried out to elucidate interrelation between the vestibular canals and the extraocular oblique muscles. In urethane anesthetized rabbits, excitatory or inhibitory effect of the canal was produced by three different methods; selective electrical stimulation of the ampullary nerve, bidirectional (ampullofugal or ampullopetal) lymphatic fluid flow, and rapid freezing of the canal. Changes of isometric tension as well as electro-myographic activity of the oblique muscles were recorded in the ipsilateral and contralateral eyes, by means of a polygraphic recorder, and the following results were obtained. 1) Electrical stimulation of a unilateral vertical or horizontal nerve caused contraction of superior oblique muscle and relaxation of inferior oblique muscle in the ipsilateral eye, and contraction of inferior oblique muscle and relaxation of superior oblique muscle in the contralateral eye. 2) Ampullofugal flow in a vertical canal and ampullopetal flow in a horizontal canal caused the oblique muscle responses which were identical to those responses produced by the electrical stimulation of the same canal nerve. 3) Rapid freezing of a vertical canal elicited the oblique muscle responses which were opposite to those caused by electrical stimulation of the same canal nerve. From the above experimental results, functional interrelation between the individual vestibular canal and bilateral extraocular oblique muscles were better elucidated. When these results were compared to those reported by previous investigators (Utzumi, Suzuki et al.), some important discrepancies were found between them. We ascribed such discrepancies to experimental errors of the previous investigators, since their results reflected theoretical contradictions in terms of vestibular eye movements.

Because of the gravitation of population toward large cities, a number of masonry buildings have been constructed since 1960. They have been rapidly deteriorated as time passed by. Therefore the purpose of this paper is to present basic data on timeworn masonry buildings which have been managed by metropolitan government and to analyse their deterioration factors. And then, the results of this paper can be used to establish the policy of managing timeworn masonry buildings. According to this study, the crack of masonry wall is the most effective deterioration factor and timeworn masonry buildings have a problem with foundation. The structure grade have an interrelation with occupancy type more than building age. Also, the longer building age becomes, the sooner deterioration speeds. A timeworn masonry building is in urgent need of reinforcement on a thirty-year period of building age.

In National Defense field, the importance of M&S and T&E has been increased due to complexity of modern Weapon System. And research reducing time and cost is being conducted continually on using limited resources efficiently. In the existing research, Weapon System's Performance Evaluation System using the Process-based method has been in progress. But, Objective basis or scientific method is insufficient in selecting appropriate function of a target to performance evaluation. Due to this, it's difficult to select functions suitable to the situation in same type. Also, Requirements of user and interrelation of evaluation factors can't be reflected systematically. In this research, it proposes the method to reflecting requirements of user, interrelation of elements in realistic situation for selecting evaluation object in Performance Evaluation Simulation. First, Evaluation Objects is selected using ANP which is multi-criterion decision making method. Second, decision support system is constructed using Programming Language(C#) based on the research result.

The objective of this study is to propose new seismic intensity parameters based on the Hilbert spectrum and to associate them with the seismic damage potential. In recent years the assessment of even more seismic features derived from the seismic acceleration time-histories was associated with the structural damage. For a better insight into the complex seismic acceleration time-history, Hilbert-Huang Transform (HHT) analysis is utilized for its processing, and the Hilbert spectrum is obtained. New proposed seismic intensity parameters based on the Hilbert spectrum are derived. The aim is to achieve a significant estimation of the seismic damage potential on structures from the proposed new intensity parameters confirmed by statistical methods. Park-Ang overall structural damage index is used to describe the postseismic damage status of structures. Thus, a set of recorded seismic accelerograms from all over the word is applied on a reinforced concrete frame structure, and the Park-Ang indices through nonlinear dynamic analysis are provided and considered subsequently as reference numerical values. Conventional seismic parameters, with well-known seismic structural damage interrelation, are evaluated for the same set of excitations. Statistical procedures, namely correlation study and multilinear regression analysis, are applied on the set of the conventional parameters and the set of proposed new parameters separately, to confirm their interrelation with the seismic structural damage. The regression models are used for the evaluation of the structural damage indices for every set of parameters, respectively. The predicted numerical values of the structural damage indices evaluated from the two sets of seismic intensity parameters are inter-compared with the reference values. The numerical results confirm the ability of the proposed Hilbert spectrum based new seismic intensity parameters to approximate the postseismic structural damage with a smaller Standard Error of Estimation than this accomplished of the conventional ones.

In this paper, we describe an image processing algorithm which is able to recognize the road lane. This algorithm performs to recognize the interrelation between AGV and the other vehicle. We experimented on AGV driving test with color CCD camera which is setup on the top of vehicle and acquires the digital signal. This paper is composed of two parts. One is image preprocessing part to measure the condition of the condition of the lane and vehicle. This finds the information of lines using RGB ratio cutting algorithm, the edge detection and Hough transform. The other obtains the situation of other vehicles using the image processing and viewport. At first, 2 dimension image information derived from vision sensor is interpreted to the 3 dimension information by the angle and position of the CCD camera. Through these processes, if vehicle knows the driving conditions which are lane angle, distance error and real position of other vehicles, we should calculate the reference steering angle.

The interrelation of secondary defects, intermediate S' phase and aging condition in Al-2.0 wt% Cu-1.1 wt% Mg alloy is studied by transmission electron microscope. The results obtained in this study are as follows. 1. High density of dislocation loops, helices and stacking faults are observed in this specimen with aging treatment. 2. The number of dislocation loops and the width of loop free zone (LFZ) are increased with aging time. 3. The intermediate S' phase precipitates and grows on the dislocations and secondary defects. 4. The misfit dislocations are formed around intermediate S' phase. 5. It is thought that the helices appear to be produced by the climb of screw dislocations, while the dislocation loops appear to be formed both by condensation of vacancies into collapsed discs and by interaction of helices with screw of opposite sign.
