Since the feasibility for the application of laser to the conservation of artworks had been demonstrated by John F. Asmus at 1972 it was known from many experiments that laser cleaning technology Provided superior characteristics over conventional cleaning methods based on mechanical and chemical actions. Then, the research and development of the cleaning technology was carried out strongly in Europe and many successful cleaning applications such as stone, painting, stained glass, paper, leather, and metal have been reported. However this is not familiar as a cleaning tool in the restoration of artworks in oriental countries including Korea. Therefore, this article aims to introduce a laser cleaning technology and its characteristics for the applications to art restoration. The contents in this article include general principles and characteristics of laser, the introduction of laser cleaning technology, and real laser applications for artwork restoration.

After dismantled, Mireuksajiseoktap(Stone pagoda of Mireuksa Templesite) is being in the stage of restoration design. Now, different ways - producing restoration model, a 3 dimension simulation - have been requested to make more detailed and clearer restoration design prior to confirmation of its restoration design and actual restoration carry-out. This thesis proposes the way to build the detailed model for better restoration plan using extensively-used Reverse Engineering technique and Rapid Prototyping. It also introduces each stage such as a 3-dimension actual measurement, building database, a 3-dimension simulation etc., to build a desirable model. On the top of that, this thesis reveals that after dismantled, MIruksaji stone pagoda's interior and exterior were not constructed into pieces but wholeness, so that its looks can be grasped in more virtually and clearly. Secondly, this thesis makes a 3-dimension study on the 2-dimension design possible by acquiring basic materials about a 3-dimension design. Thirdly, the individual feature of each member like the change of member location can be comprehended, considering comparing analysis and joint condition of member. Lastly, in the structural perspective this thesis can be used as reference materials for structure reinforcement design by grasping destructed aspects of stone pagoda and weak points of the structure. In dismantlement-repair and restoration work of cultural properties that require delicate attention and exactness, there may be evitable errors on time and space in building reinforcement and restoration design based on a 2-dimension plan. Especially, the more complicate and bigger the subject is, the more difficult an analysis about the status quo and its delicate design are. A series of pre-review, based on the 3-dimension data according to actual measurement, can be one of the effective way to minimize the possibility that errors about time - space happen by building more delicate plan and resolving difficulties.

우리나라는 지난 반세기 동안 6ㆍ25전쟁과 무분별한 국토의 개발로 인하여 문화재가 많이 파괴되고 유실되는 피해를 입어왔다. 한번 손실된 문화재는 기존 데이터 없이는 완전복구가 어려운 실정이지만, 이러한 문화재의 복원을 위해서 오늘날 아직도 일제시대의 지적도를 아무런 검증 없이 사용하고 있는 것이 현실이다. 또, 일제시대 지적측량의 기술상의 착오, 지적도면의 신축에 따른 오차를 무시하고 고분의 복원작업에 그대로 사용하고 있다. 따라서, 본 연구에서는 TS를 이용하여 일제시대의 지적도와 현재의 현황측량을 바탕으로, 일제시대의 지적도가 오늘날에 와서 고분들을 복원할 때 얼마나 이용가치가 있는지 판단 할 수 있는 토대를 만들기 위함이고, 또 과거와 현재의 자료를 비교 분석함으로써 역사적 사실을 알 수 있는 기초 자료기반을 구축하는데 있다.

The 3D virtual reality digital recovery technique is a new type in protecting and displaying remains and cultural relics through which the information of cultural relics can easily be known anytime and any where. The dissertation focuses on the study of the contradiction between quality and loading speed.

Today, the restoration of cultural properties is done by applying the latest IT technology from relying on existing data and experts. However, there are cases where new data are released and the original restoration is incorrect. Also, sometimes it takes too long to restore. And there is a possibility that the results will be different than expected. Therefore, we aim to quickly restore cultural properties using DeepLearning. Recently, so the algorithm DcGAN made in GANs algorithm, and image creation, restoring sectors are constantly evolving. We try to find the optimal GAN algorithm for the restoration of cultural properties among various GAN algorithms. Because the GAN algorithm is used in various fields. In the field of restoring cultural properties, it will show that it can be applied in practice by obtaining meaningful results. As a result of experimenting with the DCGAN and Style GAN algorithms among the GAN algorithms, it was confirmed that the DCGAN algorithm generates a top image with a low resolution.

Naju Seokdanggan, Treasure No. 49, was dismantled and reconstructed due to poor performance. During construction, the crack area was reinforced and the inclination was improved. It is necessary to analyze the stiffness changes before and after the reconstruction of these cultural properties, and to establish a database of related information. In addition, there is a need for research on a scientific non-destructive testing method capable of predicting or evaluating the reinforcing effect. In this study, a simple equation for estimating the overall stiffness of the structural system was derived from information on the elasticity coefficient and the natural frequency measured by vibration tests before and after reconstruction work, and the applicability of the equation was examined. If the stiffness of important cultural properties is regularly investigated by the suggested method, it is judged that it can be used as data to estimate the time when structural safety diagnosis is necessary or when repair or reinforcement is necessary.
