According to literature, Chengdu was built in the ancient Shu period, and Chengdu experienced nearly 3,000 years of history in this region. After the city was founded in the Qin Dynasty, there were never any natural disasters such as floods in Chengdu for more than 2,000 years. Although there were no natural disasters, due to its central location in the southwest of China, wars were frequent. Thus, how to effectively suppress the rebellion in the southwest and how to rebuild the city after the wars became the top attention of the governments of Chengdu in the successive dynasties. At the beginning of the Qing Dynasty, the government followed the Yuan and Ming systems, and the layout and architectural style of the city was similar to the previous dynasties. With the gradual recovery of the economy, Chengdu became a military center in southwest China and a military base was built in the city. Since then, Chengdu has gradually broken the original city style. Therefore, in this study, through archeological and literature sources, we analyzed the spatial structural evolution of Chengdu city in the historical background, focusing on the urban space and major building structures of Chengdu during the Qing Dynasty, which was relatively rich in information.

In-beop-dang (因法堂) is a building type that can confirm the complex space composition of the hermitage in the late Joseon Period, which is designed to accommodate various functions such as Buddhist priesthood, living spaces, and auditoriums. These facts have been confirmed mainly through plan analysis in many previous researches. However, such a plan composition has the potential to lead to more in-depth research when dealt with consideration of the Korean traditional wooden structure. In particular, the composition of upper structure in In-beop-dang with Toi-maru in front of the On-dol room can be considered from the perspective of structural response to wooden architecture in the Joseon period after the introduction of Toi-maru. Based on the achievements of these prior studies, this paper was conducted to examine the compositional characteristics, including the upper structure of the Wha-jang-am (華藏庵) In-beop-dang. In order to examine the universal aspects of structural type changes to cope with the complex spatial composition of the In-beop-dang, the cases of an in-mountain hermitage of Kim Nyong-sa(金龍寺) Temple, Geum-seon-dae (金仙臺), Yang-jin-am (養眞庵), and Dae-sung-am (大成庵).

This study was conducted to examine the architectural characteristics of Hak-seong Lee Family's Geun-jae-gong Historic House located in Seok-cheon-ri, Ung-chon-myeon, Ulju-gun, Ulsan. The house is said to have been rebuilt in the early 20th century after it was built in the 18th century, and now there are nine buildings left, including the An-chae, Sa-rang-chae, Sa-dang, storehouses and etc. This house is a large-scale house that is difficult to find similar cases in near region. The division of areas on each building is clear, and it is evaluated that it retains the typical characteristics of the head family in the late Joseon Dynasty in terms of its overall size and layout. In addition, the current wooden structure, which is said to have been rebuilt in the early 20th century, shows the composition method and space utilization method of the 3-Dori type upper structure, which have become more diverse since the late Joseon Dynasty. This has not been dealt with in the previous survey, and should be considered in detail through this paper.

Recognizing that the debate on the original form of the Seokguram Grotto is closely related to the mythologization of the Seokguram Grotto, which is far from factual understanding, this paper is prepared to restore the Seokguram Grotto based on scientific facts. To this end, we will first analyze its active meaning and fiction from three directions: the founding legend, the rediscovery story, and the concept and discourse of the Line of sight for Buddha statue (對佛像視準線), which have contributed to the mythologization of the Seokguram Grotto. The original restoration of the Seokguram Grotto should be based on a scientific understanding of the Seokguram space. However, past debates and restoration attempts have been based on imagination and not on scientific knowledge. Therefore, Chapter 3 attempts a scientific analysis of the light environment of thr Seokguram Grotto and critically examines the existing errors and realistic mythological images to correct the public's spatial perception of Seokguram's architecture and to propose a rational restoration of Seokguram's architectural space.

지하공간이용은 도심내 부족한 주거, 상업, 공업용지의 공급이라는 물리적 측 면과 경제적, 효율적 측면에서 그 가능성이 매우 높은 공간이며 다중이용시설 과 주거, 업무공간으로 수요가 증가 할 것으로 예상된다. 또한 최근에 발생한 우크라이나와 러시아의 장기 전쟁과 88년만의 폭우로 인한 서울의 인명피해는 사회적으로 지하공간을 대피 및 방재시설로도 활용할 필요성을 역설해 주고 있다. 대피·방재공간, 주거생활 및 업무공간과 관련하여 주거환경, 안전, 소방, 피난등의 시설을 갖춘 쾌적한 지하공간이 필요하게 되었다. 이러한 대피공간, 재해예방시설, 다중이용시설과 주거, 업무공간에 필요한 문제점을 파악하고 건 축법적인 해결 방안을 법률적·제도적 차원에서 접근하여 지하공간이용 활성 화 및 쾌적한 지하공간 환경이 조성되도록 개선점 등을 제시하였고 현실적인 개선사항으로 지하공간이용개발촉진지구 지정에 대한 것 등을 제안하였다.
