The stone cultural properties durability is the falling. So the conservation is easy relatively. But the conservation countermeasure of the stone cultural properties the environment pollution needed urgently as extreme. I will find out about the stone cultural properties Through the example of Restoration and conservation treatment about Bowonsabeobin-guksaboseungtap in the paper. Damage reasons of the stone cultural properties are a physical damage, a structural damage, a biology damage, a chemical damage and artificial damage. The moisture plays especially the role which damage is make the stone cultural properties. The stone cultural properties is damaged due to damage reasons. So we investigate the stone cultural properties and must remove damage reasons. Bowonsabeobin-guksaboseungtap is funerary stupa of buddhist monk with circleorientedoctagon in Geryeo Period. There is the open air. Parts of it were damaged by grave robbery in 2004. So restoration was begun in 2004.While restoring it, wrong arrangement on top of the monk-stupa was rearranged. After being arranged in right order, the middle of monk-stupa was fixed by setting up stainlesssteel shaft. A roof stone of stupa finial has cracks. So It was adhered with epoxy resin(L-30) and was washed with distilled water for pollution clearing. The stone cultural properties takes the influence of the environment pollution much because it stays at the fields. It is easy also to be robed. Therefore we must watch more with the concern.

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.

The biodeterioration with blue-green algae has been studied since 1997 up to 2000 in the tomb of King Mooryong in Kongiu, Korea. Biodeterioration in the tomb initially started from the formation of micro-organismic biofilm that had been suggested to make minor changes on the stone surface. This study revealed that the biofilm formed by microorganisms could result in permanent damages on stone cultural properties. The application of a chemical, 'K2Ol', developed by the author successfully removed fouling of biofilm on the surfaces of stone cultural properties. When small pieces of granite stone were embedded in the solution to study the side effects of the chemicals for a period of three months, the mechanical stability was 0.97 compared to control and there was no change in color. Biodeterioration is one of the most harmful factors that decrease the value of stone cultural properties but it may be treated with a development of proper chemicals.

야외 석조문화재는 다른 문화재에 비해 양적인 면에서나 규모 면에서의 한계로 인해 많은 인력을 필요로 하는 작업으로 보존처리 회사가 많은 부분을 담당하고 있다. 이 연구에서는 서울지역 관악구에 위치하는 낙성대 삼층석탑을 대상으로 실시한 보존처리 사례를 소개하고자 한다. 이를 위해 석조문화재의 보존 상태와 훼손 현황을 살펴보고 보존처리 사용 재료 및 방법에 대해서 정리하였다. 낙성대 삼층석탑과 같이 도심에 위치하는 석조문화재의 표면오염은 지역적인 특징이 나타나게 되며 이에 따라 보존처리 기법의 적용이 차별화되어 이루어지게 된다. 향후 박물관 소장 야외 석조문화재 뿐만 아니라 서울지역 석조문화재의 보존처리에 참고자료로써 활용되기를 기대한다.

The purpose of research was to find aerial algae and to investigate the change of color in each class of photosynthetic pigments in five stone cultural properties of Korea. It turned out to be a total of 29 taxa, including as 26 species, 1 variety and 2 unidentified species. Among them, Haplaosiphon fontinalis and Stigonema turfaceum were found to be newly recorded species of Korea. The average Chl-a concentration from the change of color in the stone cultural properties increased as its class; however, the class 5 showed lower values than the class 4, which was shown in previous studies. From the studies of algal distribution, chlorophytes appeared earlier than cyanophytes in stone cultural properties of algal infestation. Also, 50% or more of the five stone cultural properties already appeared to have bio-pollution.

석조문화재는 '석재'로 만들어진 문화재로 조성 목적에 따라서 여러 형태를 빌리고 있다. 그 중에서 석탑(승탑 포함)과 석불(마애불 포함)이 가장 많으며 문화사적 및 과학기술적 측면에서 가장 중요하다고 판단된다. 문화사적인 것과 과학기술적인 특징은 왜? = why? 그리고 어떻게? = how?의 관계로 나타낼 수 있다. 전자는 이유, 원인 등으로 철학적인 면을, 그리고 후자는 방법론적인 면을 의미한다. '왜?' 그들은 석탑과 석불을 제작하였으며 '어떻게' 그것들을 조성할 수 있었을까? 이와 같이, 석조문화재는 대부분 (1) 정치-사회적, (2) 종교적, 그리고 (3) 문화사적 배경에 따라 형태적 측면의 영향을 받는다. 그러므로 문화재가 조성된 배경을 종합적으로 조사 및 분석하여 석조문화재 보존처리를 위한 원칙과 방법론에 대해 기술하고자 한다.

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.

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.
