We fabricated urethane material based on properties of reversible and unfading for antic-ceramics restoration. This material with low viscosity was made hardness control possible that user want. And it have very strong adhesion and shear strength properties and is shown the best properties for pigment filling, anti-contractibility, coloring as like epoxy system materials. Particularly, the yellowing and ir-reversibility problem in epoxy restoration material were finally solved. So, there is guarantee in the eternity and stabilization of restoration for antic-celamics. And in order to show the reversible state of the restoration, we successfully dissolve this urethane materials in solvent after perfect restoring subsequently.

우수한 문화유산을 보유하고 있는 우리나라는 그간 전쟁과 관리소홀로 인하여 많이 파괴되고 유실되는 피해를 입어왔다. 한번 손실된 문화재는 기존 자료 없이는 완전복구가 어려운 실정이며, 이러한 문화재의 복원을 위해 그 모습을 수치화시켜 영구 보전함으로써 그 활용가치를 높일 수 있다. 또한, 문화재의 복원 전·후의 모습을 체계적으로 정리하기 위해서 문화재의 3차원 구현을 통한 자료의 전산화 작업이 필요하다. 따라서, 본 연구에서는 수치사진측량용 카메라를 이용하여 봉분을 촬영하고, 이렇게 취득 데이터를 사용하여 3차원형상을 수치화 하여 복원 이전의 발굴상태를 영구히 보존함과 동시에 발굴된 유적을 기초로 하여 복원시킨 봉분의 형상을 추측하기는 자료로도 활용할 수 있다. 이러한 복원 작업을 효율적이고, 신속하게 분석하여 재현함으로써 문화재의 유지관리·복원을 위한 기초 자료기반을 구축함에 그 목적이 있다.

Nowadays, the progress of high technology in modern society provides humankind with the opportunity to obtain diverse information easily and quickly. Among those rapidly progressing fields of high technology, digital media field has the ability to substitute for the multimedia information society by being applied to many related fields and daily life. Specifically, the concern and enthusiasm for the restoration of cultural property has risen. So, effective methods are required to decide on the preservation, restoration and academic value of cultural property. Among these, image processing technology using computers has been introduced. The restoration of cultural property using this technique has been studied vigorously in many advanced countries because this would allow us to restore damaged parts without destroying the original asset. However, in Korea, though we have numerous examples of cultural property with recorded history, research related to the items has scarcely been conducted. Accordingly, this study focuses on the investigation of virtual reality and the techniques applicable to restoring cultural property in addition to suggesting the significance and possibility of digitally restoring cultural property following the introduction of applicable examples both domestically and abroad.

A Urethane resin restoration material was made to be used in the restoration of stone cultural assets. The Urethane resin restoration material showed strong adhesive strength and tensile strength similar to epoxy recovery material, which had been mainly used for the recovery of stone cultural assets. The sealing property, anti-shrinking property and paint-ability of Urethane resin restoration material are also similar to existing epoxy system restoration materials. Especially, this Urethane resin restration material is expected to give permanence and continuous stability in the restoration of cultural assets made in stone by resolving the two big issues of existing epoxy recovery material, which are 'yellowing' and 'ir-reversibility'. This Urethane resin restration material had been directly applied as a filling material and adhesive and it was dissolved again. The Urethane resin, which had been used for the recovery, was able to be perfectly removed, which means that this Urethane resin recovery material has perfect reversibility. This Urethane resin restoration material also has enhanced convenience since user can adjust the working-life dependent on work environment. It is believed that this Urethane resin restoration material can also be used as a filling material or adhesive for other cultural assets made of ceramic or metal heritage, in addition to stone, since it has strong adhesive strength and tensile strength.

Today, computer graphics have moved into spotlight within many related fields. The use of computer graphics in many fields as well as in design is now universalized. More than ever, those fields which utilize virtual reality are being vigorously researched and are rapidly progressing. Many advanced countries are obtaining positive results, allowing the world to learn about their culture and history by using virtual reality techniques for the restoration of cultural property. Above all, the West has utilized the diversity of the CAVE system which could best express the artificial system among virtual reality systems. However, in Korea this technology remains in its early stages of development. Moreover, the field, digital restoration of cultural property, which will be discussed in this study, hasn't yet been explored. Accordingly, this study presents the way of digitally restoring cultural property based on the CAVE through the empirical research and suggests the significance and possibility of digitally restoring cultural properly in the CAVE system. For them, this study processes the digitally restoring of Pulguksa Temple and Sokkuram and refers to the limitation and the future study following the investigation of CAVE and the introduction of applicable examples in abroad.

The descendants have a responsibility to conserve their cultural treasure and hand it down to posterity. Most of existing wooden properties, affected by environmental factors for many years, have been rebuilt or repaired many times. Kwandeogjeong, Cultural Properties Materials 322, has gone through rebuilding or repairing 11 times. It was natural that Kwandeogjeong lost its originality and attempt to restore it was made by Cultural Heritage Administration of Korea. But the restoration depends on a piece of picture, which was taken before 1900. It had been impossible to draw any data from the picture for restoration. In this study, I was able to obtain data for its restoration through geometrical analysis, using the vanishing point of the picture. These data were also used as preliminary data for its restoration.
