In this study, the identification and distribution for rock types of the South Gate Wall of Myeoncheoneupseong Town Wall in Dangjin was investigated, and the homogeneity analysis of rock properties in the wall between the surrounding out crops estimated by examining the possible provenances. The Town Wall consists of variable rock types about 15 kinds. Granitic rocks (61.0%), quartzite (21.0%) and quartz feldspar porphyry (8.7%) accounted over 90% of total survey section. These rock properties are very similar to surrounding rocks of the Town Wall on the basis of occurrences, magnetic susceptibility, petrography, mineralogical and goechemical characteristics. Thus, it is probable that the rock properties of the Town Wall were supplied from the Town Wall around about 8km within at Seongsangri, Yangyuri, Seongbukri, Galsanri and Daedeokdong area. And supplied rock properties in the construction process, easy procurement rather than rock type was most likely seems to be considered.

This study is for species identification for each structure member such as Pillar, Bo, Changbang, Dori, Jangyeo, Judu, Donjaju, Chunyeo, Guitle, and Jongdae, of Pungnammun Gate (Treasure 308). Jeonju is the birthplace of Joseon Dynasty and Pungnammun Gate was the southern gate of old Jeonjueupseong which was walled town. Provincial Governor of Koryeo Dynasty, Yu Gyeong Choi built Jeonjubuseong and four gates at all cardinal points in 1388. And the gate was burnt down by Jeongyujaeran (war with Japan in 1597). It was rebuilt by King Yeongjo (Joseon Dynasty) in 1734 and renamed 'Pungnammun' after 34 years. It was designated for Treasure 308 for its unique style of architecture and historic values in 1963. In this study, all of wooden structure members were Pinus spp.. This result was matched for the result of major species for wooden building of late Joseon Dynasty. It can be used to complete database for architecture of Castle's Gate and help for restoration of cultural heritage in the future.

Manual control에 대하여는 국내에 소개된 지도 얼마 되지 않고 이 분야를 연구하는 학자의 수도 현재로서는 적은 편이며 이를 전문적으로 연구하는 기관 또한 거의 없는 실정이다. Manual control은 앞서 간단히 소개한 바와 같이 제어이론, 인간공학, 생체공학, 응용심리학 등이 종합하여 이루어진 학문분야로서 인간과 기계가 시스템을 이루는 분야에의 응용이 매우 광범위하다고 보겠다. 특히 공학적 측면이 강조되기 때문에 제어이론이나 로보트학과 같은 분야에서는 물론 방위산업 등 각종 산업분야에서 새로이 개발할 과제가 많아 육성이 시급하며 앞으로 이와같은 전문학술외의에 많은 참여가 있어야 하겠다.

Hwangnyongsa Temple was the large Buddhist monastery of Silla that has existed for about 685 years. The temple underwent a series of excavations from 1976 to 1983, during which it was discovered that its layout consisted of one pagoda and three main dharma halls. This discovery also led to the production of four artistic depictions of the temple at various times from its foundation to its final phase. Previous studies on the architectural layout of Hwangnyongsa Temple are largely focused on the inner sanctuary ("Buddha's Land"). The studies on the temple's main architectural structures may be natural for those who are interested in the origins of and background to its establishment, but the studies on its outer sanctuary ("Sangha's Land") have to come first to acquire a deeper knowledge of the architectural layout of the temple as a whole. To gain a comprehensive understanding of the entire layout of Buddhist monasteries of the Silla dynasty, including both their inner and outer sanctuaries, the studies on Hwangnyongsa Temple are essential as it was once the kingdom's most highly honored temple. The studies on Korean Buddhist monasteries of the Three Kingdoms Period have produced only a limited amount of information concerning the outer sanctuary, resulting in little evidence about the exact scope of the temple's sanctuary. Meanwhile, the excavations of the Hwangnyongsa Temple site have revealed the archaeological features of the walls that divided the monastery and its neighboring facilities, thus helping to delineate the size of the temple site. The excavations have revealed the boundaries between the inner and outer sanctuaries of Hwangnyongsa Temple, as well as the entire temple precincts and the exterior, providing valuable information about the changes made to the layout of the temple. In this study, the main discussion focuses on the changes made to the sanctuary of Hwangnyongsa Temple during the Unified Silla and Goryeo Periods, particularly in relation to the architectural layout of the temple. The discussion is based on a review of the periods in which the Nammunji(South Gate site) was built, which provides tangible evidence about the expansion of the temple to the south, and the walls enclosing the temple precincts on the four sides and the changes that occurred afterwards. As a result, the study concludes that both the inner and outer sanctuaries of the temple probably changed through the 1 st and 3rd. It also concludes that the changes made to the architectural layout of Hwangnyongsa Temple were intended not only to alter the scope of the temple but were also closely associated with the politico-geographical significance of its location at the center of the royal capital of Silla and the urban archaeological remains around it.

In Joseon dynasty, national roads for mainly official trips, were designed to connect capital directly to each county seat or eupchi, and militarily strategic points. The entrance of county seat where national road reach to (sometimes there has been a gate of fortress), regarded as main entrance of the county seat Also the direction county office or gwan-a ordinally heads was regarded as main entrance. Therefore, starting point of national road from county seat was not always heading for capital, but south because most of county offices head south. Nevertheless, actual traffic often ignore such a symbolic rule, and formed another practical routes.

본 논문에서는 지방환자의 서울진료의 추이와 치료결과를 살펴보기 위해 2005년, 2008년의 퇴원환자 조사 자료를 재원일수를 이용하여 분석하였다. 그 결과 2005년 퇴원환자 333,280명과 2008년 퇴원환자 419,873명의 성별, 연령별, 주진단 분포는 유사한 것으로 나타났으며 치료결과 재원일수는 2005년에 30일 이상이 7.2%, 20~29일이 5.9%인데 비해 2008년은 30일이상이 6.2%, 20~29일 6.0%로 나타나 재원일수는 절감되었다. 전체퇴원환자의 재원일수에 영향을 끼치는 요인에 대해 회귀분석 결과 연도, 성, 보험유형, 의료기관유형, 입원경로, 내원 경유, 주진단, 거주지의 효과를 통제한 후 지방환자의 진료지역에 따른 재원일수를 살펴본 결과 서울이 가장 낮은 것으로 나타났다. 또한 암환자의 재원일수에 영향을 끼치는 요인에 대해서도 연도, 성, 보험유형, 의료기관유형, 입원경로, 내원 경우, 주진단, 거주지의 효과를 통제한 후 지방환자의 진료지역에 따른 재원일수를 살펴본 결과 서울이 가장 낮은 것으로 나타났다. 즉, 지방환가 거주지에서 진료를 받는 것에 비해 서울에서 진료를 받는 것이 치료결과가 짧았다. 이는 타 지역 진료의 간접의료비 영향으로 서울지역에서 조기 퇴원하여 거주지에서 진료하였거나 서울 진료자가 중증도가 낮은 환자가 많아 재원일수가 낮을 수 있다는 것도 배제 할 수 없다. 이에 대한 중증도 보정 후 서울 진료환자의 재원일수가 낮은 요인을 분석하는 추후 연구가 필요하다.

In this paper, two general methods using time-series analysis in the functional separation of the myoelectric signal of human arm movements are developed. Autocorrelation, covariance method and sequential least squares algorithm were used to determine the model parameters and the order of signal model to describe six arm movement patterns` the forearm flexion and extension, the wrist pronation and supination, rotation-in and rotation-out. The confidence interval to classify the functions of arm movement was defined by the mean and standard deviation of total squared error. With the error signals of autoregressive(AR) model, the result showed that the highest success rate was obtained in the case of 4th order, and success rate was decreased with increase of order. Autocorrelation was the method of choice for better success rate. This technique might be applied to biomedical and rehabilitation engineering.

King Sejong's Striking Clepsydra was an elaborate timekeeping and annunciating system incorporating biological automata capable of annunciating hours, intervals and night-watches based on Shou-shih calindrical systems automatically. In this paper the author has studied the original manuscripts on the Striking Clepsydra [Sejong sillock, 65: 1a-3b ff` 16th year, 7th month(1434)] from the technical point of view undertaking a close analysis of this monumental clock and aiming to our modern understanding of the full degree of delicate mechanisms and sophisticated controls built into the night-watch and division announcing clockwork(jackwork). Based on the input/output model, timekeeping, ball-rack, ball-relay, and audible time-indicating mechanisms were synthesized reconstructing night-watch annunciating systems. It revealed that the night-watch and division announcing processes were entirely renewed automatically. Historical and philological data concerning the improvements of the proposed model were discussed.
