Stone cultural properties(pagoda, Buddhist statue etc.) is moved in original place for many reasons and restored after taking to pieces for structural safety. With the movement and restoration after taking to pieces, the cast iron is used for the sake of a fixation and horizontality. The stone cultural properties are spoiled the beauty and accelerated the weathering because of the corrosion product of cast iron. So we need to substitute for the improved property in all aspects. We are executed the corrosion test and inquired the property of material on the usable material for the shim of stone cultural properties. That is the Cast iron, Stainless steel, Titanium and Fiber Reinforced Plastics. In the result of the physical property and strength, the Stainless steel and Titanium was superior to the Cast iron. And the Stainless steel and Titanium was slower than the Cast iron in the corrosion velocity for the acid, salt and rain. If the shim is substitute the Stainless steel or Titanium for the Cast iron, the stone cultural properties are able to reduce the pollution of stone cultural properties by corrosion product and should not happen in the matter of stone pagoda.

World state of the arts of the conservation of stone monuments is reviewed and the modern conservation program based on conservation science is proposed for the scientific conservation of stone monuments in Korea. The conservation program suggests that the site environment diagnosis, decay diagnosis, petrophysical property analysis, and conservation experiment should always be carefully studied before conservation treatment. It is an up-to-date widely accepted concept in the world of stone conservation science. Our urgent national tasks that should be accomplished for the scientific conservation of stone monuments in Korea are proposed in the following: 1) The stone monument conservation projects should be planned in accordance with 'Conservation Concept of Stone Cultural Properties' and executed in accordance with the proposed 'Conservation Program for Stone Cultural Property' based on conservation science. 2) It is proposed that 'National Institute of Conservation Science for Cultural Properties' be established for systematic conservation research on the tangible cultural properties. 3) The conservation projects of stone monuments should be executed under the control of stone conservation specialist for their quality control. 4) Special national budget should be prepared for quick development of researches on conservation science in Korea.

석조 문화재의 복원을 위하여 우레탄 복원제를 제조하였다. 제조된 우레탄 복원제는 그간 석조 문화재 복원용 재료로 주로 사용해 왔던 에폭시계 복원제 정도의 강한 접착 강도와 인장 강도를 나타내고 있으며, 충진성, 수축성, 도색성 등의 물성 역시 에폭시계 복원제와 유사하게 제조되었다. 특히, 이 우레탄 복원제는 그간 가장 큰 문제점으로 대두되었던 에폭시계 복원제의 황변 현상과 비가역성 문제를 해결함으로서, 석조문화재의 복원의 항구성과 지속적인 안정성을 부여할 수 있을 것으로 보인다. 또 본 복원제를 메움제와 접착제로 직접 적용하여 사용하였으며, 이를 재 용해하여 복원에 사용된 우레탄을 제거할 수 있어 본 복원제의 가역성을 나타내었다. 이 복원제는 작업 환경에 따라 복원자가 가사 시간을 조정할 수 있도록 제조되어 사용의 편리성 또한 증진시켰다. 또 이 복원제는 강한 접착력과 인장 강도를 가지고 있어 석조문화재 이외의 도자기나 금속 문화재 등의 다양한 문화재의 메움제나 접착제로 사용이 가능할 것으로도 사료된다.

Korea has a long history from several thousand years ago. Specially stonecultural properties were used for the long period in Korea. Ancient tombs of prehistoric age, Sukgul-am (stone cave), Chumsung-dae (astronomical observatory)and stone statue of Buddha in the period of three dynasties were made of stone. There after the foundation stone, mortarstone, millstone, and other stone facilities at home have been also used for a long time. For the conservation of the cultural properties, the ecological distribution of lichens was investigated with the stone buildings around tombs and multistory stonepagodas.1. Yoo-nung (The tomb of Emperor Sungjong) : The stone buildings of granitearound tomb about 80 years old are clean and solid in quality, but they were covered in places with three kinds of lichens as the circle forms of pale-green and dark-gray colored thallus in crustose type. They were examined ecological distribution, identification and measurement of lobe size of lichens.2. Yoong-nung (The tomb of son of Emperor Yung-jong) : Granite buildings around tomb about 200 years old are also clean, moreover, they were also covered with the same kinds of crustose lichens in overlap.3. Yung-nung (The tomb of Emperor Sejong) : More than seven species of crustose, foliose and one species of fruticose lichens were growing on thegranite stone buildings built in about 500 years ago.4. Shilluk-sa multistory brick pagoda : It was built at the Koryo dynasty more than about 700 years. More than 5 species of crustose folios and two species of fruticose lichens were growing well on the granite stone at shade area. It was assumed that foliose lichens as dominant species with the respect of ecological aspect.5. Shilluk-sa multistory marble pagoda : This marble pagoda was built at the middle period of the Koryo dynasty as the same age of multistory brick pagoda. It was covered with black colored thallus such as crustose lichens. It is seemed that only crustose lichens on the stone were due to the drymarble stone. From the results described above, distribution of lichens showed that only crustose lichens on the stone from the short history (about 100-200 years) were grown with small size of circle form, stone buildings over 500 years were covered with crustose, folios and fruticose lichens, and the lichens distribution on the stonemore than 500 years appeared more foliose and fruticose than crustose type. Therefore, it is suggested that the succession of lichens on the stone buildings iscrustose$\rightarrow$foliose$\rightarrow$fruticose.Parmelia mexicana, Cladonia floerkeana, Ramalina yasudae identified are described in this paper and other unidentified species of saxicolous lichens will bedescribed later.

석조 문화재의 보존을 위한 효과적인 처리 방법으로 제안되는 가압 함침 방법으로 methyl methacrylate (MMA), MMA-butyl acrylate (PMB73) 공조성물 및 MMA-vinyl trimethoxy silane (PMV5) 공조성물을 사용하여 사암 및 화강암에 함침 처리한 후 물리 화학적 특성을 평가하였다. 화강암과 비교하여 사암의 경우 함침율이 3.2 - 3.7 wt%로 높은 값을 보였고 고압 반응기 내에 감압 공정 도입 시 32%의 함침율 증가를 나타내었다. 물리화학적 특성인 발수성, 휨강도, 충격특성 및 초음파 속도 등도 화강암보다 사암에 대해 아크릴계 가압함침 처리제의 효과가 두드러지게 나타남을 알 수 있었고, 이는 사암의 공극이 많아 단량체 함침율이 크기 때문으로 해석할 수 있었다. 아크릴계 처리제별 사암에 대한 충격파괴 에너지는 PMMA의 경우 1.22 J, PMB73은 1.84 J, 그리고 PMV5의 경우 2.8 J을 나타내었다. 충격 특성에서 무기 특성을 개선한 PMV5가 최적의 성질을 나타내는 것은 아크릴계 처리제의 분자 구조보다는 처리제의 무기 친화 특성이 석재의 충격 특성에 더 많은 영향을 주기 때문으로 해석할 수 있었다.

최근 등록문화재로 등록된 옛 담장의 사례는 기존의 '점' 단위의 개별 건축물에서 '면' 단위의 마을까지 문화재의 범주를 확대시켰다는 의미를 갖고 있다. 또한 급속한 사회변동에 따라 주거양식이 변화하는 상황 속에서 농 어촌의 전통적 경관의 훼손과 멸실을 방지하고자 추진된 의미 있는 정책이라 할 수 있다. 본고에서는 이러한 옛 담장이 갖고 있는 문화적 요소를 도출하고 구술조사를 통하여 그 의미와 상징체계를 분석하였다. 전통문화의 문화적 자원을 문화콘텐츠화 하려는 노력이 요즘 다양한 측면에서 이루어지고 있지만 기존의 연구들은 너무 미학적인 측면만 강조하거나 건축적인 해석이 주를 이루고 있다. 특히 본고의 연구대상인 옛 담장의 경우는 단순히 관광코스로 소개되는 경우가 대부분이다. 따라서 구술조사를 토대로 이야기를 구성하고 관광객이 함께 공유할 수 있는 창조적인 접근이 필요하다. 문화콘텐츠란 문화의 원형과 문화적 요소를 발굴하고 그 속에 담긴 의미와 가치를 찾아내어 그것의 원형성, 잠재성, 활용성 등을 매체에 결합하는 새로운 문화의 창조 과정이다. 본고에서는 근현대 생활문화 공간복원과 문화콘텐츠의 발굴과 관련하여 상학리 돌담장을 조사하여 활용가능성을 검토하였다. 더불어 조사된 자료를 분석하여 스토리텔링을 활용한 장소마케팅의 가능성을 고찰하여 보다 독창적인 관광자원화 방안을 제안하였다.

We tested to obtain the excellent Epoxy resins on the property of matter. Existing Epoxy resins is tested to regulate the viscosity, color and hardening time etc. Benzen-ring structure of Bisphenol A type (AY 103) is replaced by Hydrogenated B.P.A type. And hardener is replaced by Polyoxyalkylene Amine. So we are developed into the two resins(L-30, L-40).To know if this Epoxy resins was fitted to repairing and restoration of stone cultural properties. Three kinds of Epoxy resins (AY 103, L-30, L-40) are tested on the artificial weathering test, freezing-melting test, exposure test etc. As a result of test, L-30 is less the discoloration than that of other Epoxy resins and was superior to the excellent property of matter.

The stone lantern of the Damyang Gaeseonsaji temple site is a cultural heritage built during the Unified Silla period (AD 868). The reason for its value as a cultural property is due to wittern the background and the period created on inscription of the lamp stone engraved by letters. The stone lantern consists of two types of lithic tuffs for the 23 original properties, the replaced stones in 1991, and the biotite granite for its ground stones replaced in 2005. The lithic tuffs selected as the replacement parts in 1991 and 2017 have been examined and got to properties of hardly exposure moisture as well as very similar geochemical characteristics. There were various types of physical deterioration of the stone properties and structural cracks; in particular, on the northern side of the stylobates. Chemical and biological deterioration can be identified as black, white, and brown discolorations as well as by the presence of lichens, bryophytes, and herbaceous plants. In the evaluation of the physical properties of the stone lantern, the mean and maximum ultrasonic velocities were found to be similar in each direction. However, the lowest velocity on the east and south sides were found to be lower than those of other stone properties. It was found that physical damage to the stylobates resulted from water expansion in a freeze-to-thaw phenomena related to water content. Therefore, dismantling repair was carried out in the protection facility to restrict further water supply to the stone as much as possible.

Precise scientific-diagnosis for preserving stone cultural properties has been well-advanced, but research on proper methods for conservation, restoration and repair is still in early stage. Accordingly it is quite difficult to establish conservation treatment methods compatible to unique characteristics and environments of each cultural property. We tried to select most compatible conservation materials through thorough assessment of conservation materials in current use. This research is focused on conservation and restoration materials except cleaner, which are used as adhesive, filler, repellent and consolidant. Conservation treatments for stone cultural properties were first tested in 1960's and have been carried out by various methods under relevant organizations and conservation treatment companies since. We investigated present status of conservation materials being used for cultural properties. Based on these data, we will look through types and properties of the conservation materials to figure out existing problems. Among many kinds of resins, the ratio of conservation materials used in cultural properties is very low. Therefore, new conservation materials equipped with proved long-term stability should be developed as soon as possible.
