The korean oriental medicine dose not actively apply San syndrome(that is, colic syndrome) to the clinic because its concept is not established concretely even though it has definitely existed as a disease of human being from the time of Naegyeong to these days. Thus the author writes this thesis to establish the concept of San syndrome by the research of literature for the purpose of promoting clinical application. Study on the concept of San syndrome through the statements written by medical practitioners of each period comes to the following conclusions. The concept of San syndrome stated by various medical practitioners does not deviate from that in Hwangjenaegyeong. Most of them simply modify and supplement it. San syndrome refers to the case when the contents of abdominal cavity protrude to outside and when swelling and pain around the genital organs, or fierce pain in abdomen comes with constipation and dysuria. There are three methods of classifications of 7 San syndromes in large. The first one is the classification in Hwangjenaegyeong, the second one is that of So WonDang, and the third one is that of Jang Jahwa. Among them ,Jang Jahwa's classification has occupied the most influential position since Hwangjenaegyegng, in which, there are seven Sans; Han-San, Su-San, Geun-San, Hyul-San, Gi-San, Ho-San, and Toe-San. On the basis of his classification, the concept of San syndrome is established by posterity. The causes of San syndrome are claimed in three ways. In Hwangjenaegyeong , Cold and Ki are described. Ju Dangye asserted Damp-Heat. Heo Jun maintained Cold, Ki and Damp-Heat. Ju Dangye made enlargement and progress on the etiology in Hwangjenaegyeong from Cold and Ki to Damp-Heat. Heo Jun reasonably combined Cold, Gi, and Damp-Heat as the pathogen of San syndrome. There are two meridians closely related to San syndrome. In Hwangjenaegyeong, the Conception meridian is designated, Ju Dangye insisted on the Liver meridian of Foot Gyuleum. His theory that the Liver meridian entirely governs San syndrome is accepted by posterity. Ru Young in Myeong dynasty complementarily combined the concept In Hwangje -naegyeong, classifications of Jang Jahwa, and Ju Dangye's theory. He was followed by Gong Jeonghyeon, Lee Cheon, and Heo Jun, and finally related to Jisan in present time. Heo Jun has completed the standard of San syndrome by combining opinions of anterior medical practitioners. He complied with Naegyeong and Yang Sayoung's view in symptoms, and classified into seven categories according to Jang Jahwa's advocation. In the pathogenesis, he followed up Naegyeong in which Cold and Ki were designated as a cause and Ju Dangye's theory that San syndrome was caused by Damp-Heat, congested fluids, retention of undigested food, and stagnated blood. For meridians, he agreed with Ju Dangye's assertion that the Liver meridian entirely governs San syndrome. About Hyungsang of face, Lee Cheon indicated that if the part behind ear was sunken, the person had his kidney hanged below, and if the person had his kidney hanged below, he was susceptible to lumbosacral pain and Ho-San syndromes. Afterwards, Jisan pointed out that persons with the following characteristics in Hyungsang should be considered to have San syndromes; droopy ears, asymmetric wings of nose, unbalanced eyes, curved nose, asymmetric testicles, turned up nose for man, and long nose for woman. By recognizing the concrete features of Hyungsang, Jisan founded Hyungsang medicine, the horizon of oriental medicine.

본 논문에서는 ATSC 지상파 디지털TV 방송신호를 중계하는 EDOCR 시스템에서 송수신신호의 주파수 동기를 위해 제안된 알고리즘에 대해 기술한다. 또한 수학적 등가모델을 사용하여 제안 알고리즘을 검증하고 제안 알고리즘을 적용한 EDOCR시스템의 성능을 분석하였다. 제안하는 알고리즘은 주 송신신호의 동기복원 과정에서 획득한 주파수 오차정보를 재 변조 과정에 사용함으로써 GPS와 같은 별도의 부가 장치 없이 송수신신호의 주파수를 일치시킬 수 있고, ATSC 송신신호 규격을 만족시키는 재전송신호를 발생시킬 수 있다. In this paper, we propose an algorithm which makes the frequency of output signal synchronize with frequency of input signal in Equalization Digital On-channel Repeater (EDOCR) system which was proposed to overcome the disadvantage of conventional Digital On-Channel Repeater (DOCR). Also, we verify the algorithm by using the mathematical equivalent model and analysis the performance by implying the algorithm to EDOCR. The main idea is to use the frequency offset information, which comes from carrier recovery in the receiving part of EDOCR, when the demodulated symbol is re-modulated in transmitting part. Based on the proposed algorithm, EDOCR not only makes the output signal synchronized with input signal in frequency but also emit the output signal which satisfies the ATSC transmission standard without additional equipments such as Global Positioning System (GSP).

The following conclusions are drawn, through studying of referring literature, of contents of the prescription and of clinical applications in Hyungsang Medicine. Insamyangyung-tang(인삼양영탕) was appeared first in Taepunghyemin-whajegugbang(태평혜민화제국방) which was written by Jin and others at Song Dynasty. This prescription is applied to senility and long lasting weakness, little strength of spleen and lung(비폐기허), and insufficiency of blood. The Insamyangyung-tang is composed of medical stuffs which Rhizoma Cnidii is taken out from Sipjiendaebotang and Pericarpium Citri Nobilis, Fructus Schizandrae, Radix Polygalae are added to it. This prescription is used in China up to the present. In korea, according to Donguibogam, Rhizoma Cnidii and Poria are taken out from Sipjiendaebotang and Pericarpium Citri Nobilis, Fructus Schizandrae, Radix Polygalae are added to it, and Ramulus Cinnamomi is changed to Cortex Cinnamomi, and also Radix Ledebouriellae is newly added to it. This is reorganized to fit for Korean physical conditions and to be useful for deficiency of blood, and also to be efficacious for coming and going of chillness and fever and running with sweat due to weakness of Liver. In the point of view of Hyunsang medicine, Insamyangyung-tang is applied to shapes and symptoms as follows : This prescription becomes more efficacious to women than to men. At the age of fifties when liver grows weak it effects a cure. It takes effect to the shape of going easily into the deficiency of blood, that is, to the Hyul Kwa with an oval face. It effects a cure on the man who has wrinkles on the bridge of the nose, who has marks of being choked up on the central area between two brows, or who has distinctive size of eyes and nose. It is efficacious against symptoms which are to be exhausted, to be weak, to lose flesh, to be coming and going of chillness and fever and running with sweat.

Objectives : This study was carried out to research antioxidant effects of Sagunja-Tang(SA) through in vitro and vivo experiments, and tried to investigate the relation between oxidation of tissues and deficiency of Qi. Methods and results : HPLC analysis of glycyrrhizine - known to be the main compound of Radix Glycyrrhizae - was done to certify the quality of SA. Chemiluminescence was initiated by adding tort-butyl hydroperoxide (t-BHP) to rabbit polymorphonuclear leukocytes (neutrophils), and generated reactive oxygen species (superoxide anion) decreased significantly by SA as dose dependent manner. Cell injury during 60 minutes tissue incubation was initiated by adding t-BHP, a hydrophobic hydroperoxide and $H_2O_2$, an water soluble oxidant to rat renal cortical and liver slices. Percentage cell death and lipid peroxidation were estimated by measuring lactate dehydrogenase (LDH) and malondialdehyde (MDA), a product of lipid peroxidation. t-BHP induced % cell death of renal cortical slices and lipid peroxidation of renal cortical and liver slices were decreased significantly by SA. SA decreased significantly % cell death and lipid peroxidation of renal cortical and liver slices induced by $H_2O_2$, too. Acute renal and liver injury induced by $HgCl_2\;and\;CCl_4$, which initiated from free radical, were applied to mice and metabolic data were obtained. Data showed protective effects of SA on acute renal injury caused by decrease of glomerular filtration. SA protected acute liver injury too. Conclusions Through this study, we found that SA have antioxidant effects and tissue oxidation was similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

새로이 合成한 화합물인 trans-2-butenedial bishydrazone의 AA'BB' 型 NMR 스펙트럼에 나타난 피이크는 모두 2개의 line이 重疊되어 있어서 보통의 방법으로는 internal check이 불가능하다. 5가지 파라미터 ${\delta}$, K, M, N, L을 漸次的으로 변화시켜 二重線의 中間點이 실제 line의 위치에 接近하게끔 함으로써 정확한 line의 位置를 알아내었으며 그 결과로부터 chemical shift와 coupling constant의 값을 구하였다. The NMR spectrum of newly synthesized compound, trans-2-butenedial bishydrazone is analyzed. It is found that each peak in the AA'BB' spectrum of the compound is consisted of two lines and internal check cannot be accomplished by the usual analytical procedure. Correct line positions are obtained by varying gradually all the parameters, ${\delta}$, K, M, N, L so that the mid points of the doublets may approach observed line positions and the chemical shifts and the coupling constants of the compound are obtained from the result.
