천년의 고도라 불리는 경주는 관광의 도시답게 여러 유적지, 문화재가 곳곳에 있다. 우리가 학창시절 교과서에서 배웠던 석굴암, 첨성대 등도 의미있고 소중한 문화재이지만, 이외는 조금 다른 멋이 있는, 땅거미가 지면 낮과는 또 다른 아름다움이 펼쳐지는 곳이 있다고 해서 찾아가 보았다. 동궁과 월지(안압지)는 경주시 인왕동에 자리한 신라 문무왕 14년(674)에 축조된 궁원지(宮苑地)다.

일본의 기상학자 화전웅치는 1910년, 세종 24년 세계 최초로 제작된 우리나라 대표적 발명품인 측우기를 불어로 쓴 논문을 통해 세계에 소개했다. 화전은 프랑스에서 기상학을 공부하고 돌아와 일제가 우리나라에 세운 제물포관측소 소장으로 근무하면서 측우기는 물론 경주 첨성대도 현장 답사하여 세계에 소개한 주인공이다.

For this study, the full-scale model of Chumsungdae was selected as an object, and various photographs were obtained with metric camera for forming circular strips and blocks. The accuracies were analyzed according to the change of object distance and different configuration of control points by bundle adjustment, and the characteristics of results obtained through combined strips were drawn. This thesis suggests optimal analysis technique of cylindrical structures requiring all-side analysis such as cultural properties. As a result, it is possible to use control points positioned on only any one-side for all-side analysis, and control configuration is more important rather than the number of control points for increasing accuracy. In addition, it is desirable to locate control points in X, Y and Z plane uniformly, and it was shown as object distance was shorten and the number of combined strips increases, the accuracy of results was improved considerably.

The Mogok metamorphic belt is a highland area mainly consisting of Archean crystalline rocks, where many ruby mines were distributed in the past, and jewelry has been identified in its alluvium as placer deposit. Minerals that are usually identified with ruby include spinel, garnet, and rubellite. The conglomerates that form the alluvium in which jewelry is found mainly consist of gneiss and clastic pegmatites. In Singu, Mogok, and Momeik areas, a number of pegmatites containing jewelry are distributed in the intrusions of Mogok metamorphic rocks, diorites, and granites. In Singu pegmatites, rubellite, goshenite, and blue and violet apatite occur as gems. In Momeik pegmatites, mushroom-type rubellite, petalite, hambergite, pollucite, and aquamarine can be found. In Mogok pegmatites, topaz, aquamarine, goshenite, and herderite occur are present.

Recently, the occurrence frequency of earthquake has increased in Korea, and many cultural assets have been damaged. Cheomseongdae is a valuable cultural assets that must be preserved historically and culturally. But, the masonry structure such as Chemseongdae is vulnerable to lateral forces. Therefore, in this study, structural modeling and dynamic analysis are performed to reflect the ground state and structural form of Cheomseongdae. Also, discrete element analysis technique is applied and dynamic behavior characteristics are analyzed according to earthquake load. For this purpose, displacements and stresses according to locations are reviewed and then swelling and distortion are analyzed.
