Jangneung (the Royal Tomb of King Danjong) and Sareung (the Royal Tomb of Queen Jeongsun) are simple in their design and layout. Not only are the sizes of the stone statues small, but stone soldiers are not installed at all despite the fact that Danjong at one point served as the King of Joseon. Moreover, only a pair of seoksu (stone animal) is installed for each Tomb. These royal tombs were originally made as common tombs and later upgraded as Royal Tombs when Danjong's royal status was reinstated posthumously in 1698. Thus, in comparison to royal tombs in general, the scale of these tombs is by far modest. For this paper, archival records and other literature for the burial upgrade process and the stone sculptures are examined; also, the stone sculptures have been examined and measured on-site, and they have been compared and analyzed based on the data thus obtained. Furthermore, this paper traces the historical context of the period in which the simplification of the stone sculptures took place for Jangneung and Sareung. The paper argues that the cause of the modest scale lies not so much in the fact that King Danjong had been dethroned as a commoner, but in the cataclysmic famine and epidemic that swept the country during the time when the two royal tombs were upgraded as such.

표면성장법을 이용한 고강력, 고탄성률 섬유의 제조시, 결정화 온도에 따른 섬유 미 세구조와 물리적 성질의 상관 관계를 미세구조적, 열역학적 관점에서 규명하고자 초고분자 량 폴리에틸렌으로 섬유를 제조하고 결정화 온도에 따른 구조와 인장 성질의 변화를 용융 거동을 중심으로 관찰하였다, 일정길이하에서의 섬유의 용융인 제한 용융에서는 고분자 사 슬배좌의 구속으로 인해 사방정계-육방정계 전이가 일어났다 제한 용융 거동으로부터 라멜 라 구조와 펼쳐진 사슬 결정 부분을 분리할 수 있었으며 결정화 온도가 증가할수록 펼쳐진 사슬 결정의 양이 증가하였다. 결정화 온도가 증가할수록 쉬시-케밥구조에서 펼쳐진 사슬 구조로의 변화가 일어났으며 결정내의 결점도 줄어들었다. 결정화 온도가 증가할수록 구조 의 변화로 인해 인장 성질이 향상되었다. 인장 성질은 펼쳐진 사슬 결정의 양에 큰 영향을 받았다. 인장 강도는 펼쳐진 사릉의 양과 사슬내의 결점들에 의해 큰 영향을 받았으며 인장 탄성계수와 절단 신도는 인장 강도보다 펼쳐진 사슬의 양에 더 크게 영향 받았다.

The purpose of this study is to investigate conservation and management methods of the Joseon Royal Tombs under the Eastern District Management Office. Through the literature survey, we understood the process of change of Joseon royal tombs, and through field surveys and interviews, we understood the status of the interior and the surrounding area. In this process, topography, land use and flow of human traffic, architecture and stone objects, water system, historical forests, and facilities were set as the main evaluation indicators. Urbanization has damaged the original terrains of Royal Tombs as national roads, buildings and facilities have constructed in the inner and outer area of Joseon Royal Tombs. Construction of underground passage, land purchase, relocation and demolition of the buildings are required for the conservation of the Royal Tombs area, and then it is necessary to recover the original terrain. In the case of land use and pathways, there are many disconnection of the original ritual circulation, they should be maintained to remind the sacred atmosphere of the royal tomb. And It is necessary to collect accurate information on the lost buildings and stoneworks through literature survey and excavation investigation, and that investigations should be lead to the exposure or restoration of the ruins. Historical forests require periodic and ongoing monitoring and management, and it is necessary to establish new entrance area and appropriate facilities following the long-Term conservation and management plan. These plans should be classified into short, medium and long-Term projects according to urgency and securing financial resources with a long perspective to implement continuous and systematic projects.
