Before the 15th century, the main buildings of the residences of the ruling class in Seoul consisted of Momchae(身梗), Seocheong(西廳), and Naeru(內樓)‧Chimru(寢樓). Based on the equality of the relationship between husband and wife, the couple lived in the main building[Momchae] in the center of the mansion, but based on the individuality of the relationship between husband and wife, each had an area consisting of the same section within the building. Naeru‧Chimru was the two floors bedroom building became a common living space for the minister and wife, upstairs in summer, downstairs in winter. In preparation for large gatherings and important receptions, an open-structured West Hall(西廳) was located on the west side of the mansion. Momchae, Seocheong, and Naeru‧Chimru were the common building types and layouts of the residences of the highest ruling class, including high-ranking officials, until the reign of King Sejong. However, from around the time of King Seongjong, Seocheong and Chimru came to be regarded as privileged and luxurious buildings only allowed for the grand prince's residence. The layout of the bedroom, main building (including Wings), Outer Sarang[外舍廊], and Joyangru[朝陽樓] of Prince Bongrim's mansion built in the first half of the 17th century clearly shows the transitional period when the arrangement of chimru, main building, and western office was disrupted and the layout changed to the Inner main building(Anchae for wife) and Outer main building(Sarangchae for husband).

원전 구조물의 실시간 모니터링 기술이 요구되고 있지만, 현재 운영 중인 지진 감시계통으로는 동특성 추출 등 시스템 식별이 제한 된다. 전역적인 거동 데이터 및 동특성 추출을 위해서는 다수의 센서를 최적 배치하여야 한다. 최적 센서배치 연구는 많이 진행되어 왔 지만 주로 토목, 기계 구조물이 대상이었으며 원전 구조물 대상으로 수행된 연구는 없었다. 원전 구조물은 미미한 신호대잡음비에도 강건한 신호를 획득하여야 하며, 모드 기여도가 저차 모드에 집중되어 있어 모드별 잡음 영향을 고려해야 하는 등 구조물 특성을 고려 해야 한다. 이에 본 연구에서는 잡음에 대한 강건도와 모드별 영향을 평가할 수 있는 최적 센서배치 방법론을 제시하였다. 활용한 지표 로서 auto MAC(Modal Assurance Criterion), cross MAC, 노드별 모드형상 분포를 분석하였으며, 잡음에 대한 강건도 평가의 적합성을 수치해석으로 검증하였다.

Studies and reports on buddhist temples in Goryeo dynasty are rarely in the present situation. At this point of time new excavational reports and historic records offer many materials to understand a architecture in Goryeo period. Especially, temple site have various transitions, it is of great value to study. This article attempted a restorative study of a location, function, spacial arrangement, structure, building age is based on a measure and transition of temple layout that is based on the excavational result and related historic documents about Godal temple site in Yeoju. Godal temple site was a representative Zen buddhist temple in Goryeo Dynasty. It was difficult of access by watercourse because it was located in an inland in the upper Han River. Archaeological research and historical records has reveals that the temple was constructed with a minium of four levels[six terms]. We could recognized the central site of temple and buildings were constantly established, enovated or collapsed. It has went through many transition according as it encountered new sects and doctrines. Also it should perform various functions and overcome given conditions. Ultimately it let see greater diversity in the spacial composition, and layout. That is to say it were planed several separate areas, each was consisted of main buildings, once again was integrated into one temple.

There are two main halls in the Main Palace of the Koryo Dyansty in the 11th and 12th century. One, named Hoekyongjeon, was served only for special ceremony ; hundred Buddhist priests' sermons or receiption of Chinese emperor's letters. The other one, Kondukjeon, was used as ordinary throne hall. The ordinary throne hall was built when the palace was erected at the beginning era of the Koryo Danasty, while the special ceremony hall built after the reconstruction in the 11th century. The throne hall was located at northwest side of the special ceremony hall. Audience chamber and King's bedroom were located at west and northwest side of the throne hall. The basic layout of the Palace showed unsymmetrical shape. It seemed mainly effected by its undulating terraine. The acess road from main gate to the throne hall showed zigzag way, by following a stream penetrating the site obliquely, It could be said that the Main Palace of the Koryo Danasty achieved its originality on the aspect of unsymmetrical layout and zigzag acess road, which was not found in the former palaces.
