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.

현대 무기체계의 복잡체계화로 인해 국방은 M&S와 T&E가 중요시되고 있으며, 한정적인 자원을 효율적으로 운용하여 시간 및 비용을 절감할 수 있는 연구를 지속적으로 진행하고 있다. 기존연구에서는 프로세스 기반 모델링을 이용한 성능평가 시스템 개발이 진행되고 있지만 성능평가에 합당한 무기체계의 기능을 선정하는데 있어, 객관적 근거나 과학적 방법 이 부족하기 때문에, 같은 기종이라도 상황에 적합한 기능을 선정하기 어렵다. 또한 사용자의 요구사항을 체계적으로 반영할 수 없으며, 다양한 평가요소의 상호작용을 고려하기 힘들다는 문제점이 있다. 따라서 본 논문은 성능평가 시뮬레이션에서 사용되는 평가객체 선정 시, 객체 선정기준과 사용자의 요구사항 및 현실적 상황을 반영할 수 있는 방법을 제시한다. 먼저, 다 기준 의사결정 방법인 ANP기법을 이용하여 객체를 선정하고, 연구결과를 바탕으로 프로그래밍 언어(C#)를 이용한 의사결정 지원시스템을 구현하였다.

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.
