The results from the Individual Plant Examination of External Event of Yonggwyang nuclear power plants, unit 3 & 4, in Korea have shown that the high degree of diversities of the experts' opinions on seismicity and attenuation models is su, pp.sed to be generic cause of uncertainty of APEs(annual exceedance probability) in the PAHA(probabilistic seismic hazard analysis). This study investigated the sensitivity of the focal depth, which is one of the most uncertain seismicity parameters in Korea, Significant differences in resultant values of annual exceedance probabilities and much more symmetrical shape of the resultant PDFs(probability density functions), in case of consideration of focal depth, are found. These two results suggest that, even for the same seismic input data set including the seismicity models and ground motion attenuation models, to consider focal depth additionally for probabilistic seismic hazard analysis evaluation makes significant influence on the distributions of uncertainties and probabilities of exceedance per year for the whole ranges of seismic hazard levels. These facts suggest that it is necessary to derive focal depth parameter more effectively from the historical and instrumental documents on earthquake phenomena in Koran Peninsula for the future study of PSHA.

In this paper, we have studied Sogyupyo (小圭表, small noon gnomon) of the Joseon dynasty. According to the Veritable Records of King Sejong (世宗, 1418 - 1450), Daegyupyo (大圭表, large noon gnomon) with a height of 40-feet [尺] was constructed by Jeong, Cho (鄭招) and his colleagues in 1435, and installed around Ganuidae (簡儀臺, platform of Ganui). On the contrary, the details of Sogyupyo are unknown although the shadow length measurements by Daegyupyo and Sogyupyo are found on the Veritable Records of King Myeongjong (明宗, 1545 - 1567). By analysing historical documents and performing experiments, we have investigated the construction details of Sogyupyo including its development year, manufacturer, and installation spot. We have found that Sogyupyo would be manufactured by King Sejong in 1440 and placed around Ganuidae. And Sogyupyo would be five times smaller than Daegyupyo, i.e., 8-feet. On the basis of experiments, we suggest that although it is smaller, Sogyupyo was equipped with a bar [橫梁] and a pin-hole projector [影符] like Daegyupyo in order to produce the observation precision presented in the Veritable Record of King Myeongjong.

As the current stage of the fashion begins to follow the styles of the past the study on the past costume is getting more importance and as the methodolgy of the study the accu-rately approached study through the rehabili-tation of the past cosume is more needed than the simple rearrangement of the historical documents. By this methodology this study can be positioned as a re-creation activity. The results of the study are as follows. 1) Style: The general silhouette is the style to emphasize the waist and to widen skirt at the lower part of the body. The front shows hourglass silhouette but the side shows S-line silhouette. The dress is two-piece composed of bodice and skirt. 2) Color and Fabric: The main color is dull powder blue end the sub color is ivory. The dress is made of wool crepe and cotton and partly silk crepe satin and taffeta. 3) Pattern and sewing: The dress is combined with lining and fabrics, The patterns. or overbodice. The skirt is gored skirt. The skirt is gored skirt. The dress has various effect not only to decorate but also to conceal seams support hemlines nd affect the depth and length of front panel. 4) Datail: The braid black velvet ribbon frill and tucks in bodice skirt sleeves front panel collar cuffs are repeatedly used to dec-orate the dress. Finally the 1902-3 day dress has the characteristics of transitional stag in which the chatacteristics of the costume of 1900s and the remnants of the characteristics of the pre-vious costume style and shows the charac-teristics of day dress well in terms of the style color and fabric pattern and sewing and detail.

조선시대에 도성의 개천과 한강변에서 하천 수위를 측정하였다. 세종 23년(1441년)에 측우기와 수표(水標)를 제작하여 강우량과 하천수위를 측정하기 시작한 것이다. 수표는 지금의 청계천과 한강변두 곳에 설치하였다. 와다유찌는 조선고대의 관측기록을 정리하면서 측우기 기록을 분석하였고, 수표 기록을 정리하였다. 본 연구에서는 고문헌 자료에서 수표 관측 기록을 복원하여 조선의 도성인 개천(청계천)과 한강의 홍수 기록을 복원하는데 활용하고자 하였다. 본 연구에서 복원한 승정원일기와 기우제등록에 수록된 수표의 관측기록은 와다유찌가 조사한 기록을 상회한다. 와다유찌가 조사한 기록은 명종 1554년부터 영조 1778년까지인데, 1554년의 기록은 1회에 그치며, 인조11년(1633) 이후의 기록이 대부분이다. 이 점은 기우제등록의 경우도 유사하다. 기우제등록은 인조 11년부터 고종 26년(1889)까지의 기우제, 기청제, 기설제에 대한 기록을 정리한 것으로 전체 6권으로 구성되어 있다. 기우제 기록과 함께 수표기록(중부, 남부, 한강 및 수표)이 포함되어 있다. 기우제등록에 수록된 수표기록은 총 690회에 이르지만, 1779년 6월 11일의 3척 5촌을 마지막으로 더 이상의 기록은 찾아볼 수 없다. 숙종의 재위 기간에는 1669년부터 1791년까지 매년의 홍수상황이 기록되어 있다. 당시 한강의 수위와 도성안 개천에서 중부수표와 남부수표 2곳의 수표 기록을 있으나, 숙종 23년(1697)부터는 중부수표만 기록되어 있다. 이 지점에서의 10척을 상회하는 홍수는 20번의 기록이 있다.

The purpose of this consideration is to present fundamental data for understanding and development the historical approach of Korea Protection by re-examining Royal guarding system through the history in Early Chosun Dynasty. This paper initiated from this critical mind seeking to understand the changing phase of Korea Guarding system, and fundamentally to find the future-oriented ways for the Guarding system. The main materials of history in Early Chosun Dynasty were re-examined, investigated and analyzed and the main references are a code of laws and official as well as private documents such as Kukjo-Oreyeui. Guards system for Royal prince has been found in Byung-jeon of Kyungguk-daejon. he Guards organization has dual system, one was Gumgun which was a private military man and the other was Wuibyung which was a Central military man. On the contrary, central military man were normally protected the royale palaces, but when the King come and go they accompanied and protected the King in safety zone. But just in case they did a job as a member of capital protection military affairs. A question of finance was the reason why there had been dual protection system due to financial matter. If it increased number of man it would pay much money, therefore central military man who has no relevance to national finance were supplied as members of military affairs for the protection of king.

There have not been many debates on the subject of Korean architecture during the transformative period of Gae Wha Gi (開化期: Enlightenment Period of Korea), when Western-style buildings first appeared in Seoul. This study begins by finding and recording those buildings in Seoul that show the gradual adoption and appropriation of Western architectural elements at the turn of the 20th century. By exploring the confluence of two different architectural styles, this paper attempts to look carefully at the hybrid conditions that resulted from encounters between the Koreans and the Westerners in the late 19th and early 20th century. Beginning with discovering the first products of the Western architectural influence in Seoul, this study explores the uneasy co-existence between the traditional Korean architectural style, and the Western architectural style. This co-existence ultimately bred new building techniques, and interior layouts; the appearance of these hybrid buildings illustrate the gradual transition from the traditional way, in which users modified, combined and appropriated various elements from both styles. Analyzing historical documents and photos, this study tries to capture a detailed image of the period when the influence of the Western architecture had an unavoidable impact and brought change to the traditional architecture of Korea.

This study is to introduce the SDI(Selective Dissemination of Information) system, a typical aspect of information retrieval systems nowadays quite popular. The term "SDI" is most often used to describe systems of using electronic data processing equipment as a means of matching the terms of user-interest profile against document descriptors and selecting those documents with a specified degree of similarity to the terms of the user-interest profile. Various up-to-date informations on SDI systems developed after the first introduction of the original idea by "Luhn" are reviewed and compared. The stage of development, structure, characteristics, and various other matters concerning the SDI systems are analyzed and discussed.

In order to restore the Hwangsanbeol Combat at present, it is necessary to make a close examination on the name of the military cops, the number of units, and the numerical strength, an unit organization, and a combat formation. Based on Samguksagi, Samgukyusa, other historical documents and military history information, I tried to restore the Hwansanbeol Combat as follow. The Shilla, at the 7 year of Mooyeol Dynasty, AD. 660, maintained 35 military units. The Shilla committed18 military units from among 35 units to battle against Baekje at the 7 Year of Mooyeol Danasty. The names ofmilitary units are as follow: 1) Daedang, 2) Sangjoojeong, 3) Hajoojeong, 4) Seodang, 5) Nangdang, 6) Eumlihwajeong, 7) Samryanghwajeong, 8) Sosarnjeong, 9) Namcheonjeong, 10) Leehwahaejeong, 11) Kaegeumdang, 12) Geupdang, 13) Nodang, 14) Woonjaednag, 15) Chungdang, 16) Suktoodang, 17) Gwidang, and 18) Soogun. The numerical strength, which the Shilla maintained at the year of A.D. 660, was total 106,353 persons from 35 military units. Shilla committed 57,433 military personnel to combats against the Great Baekche. Ground Forces from the 57,433 personnel were 58,343 persons, and the naval forces were 9,100 persons. Finally, 2,602 persons from among the 9,100 naval forces were only combating forces, and non-combat forces were 6498 persons.
