It is not easy to define the priority criteria of the need of conservation treatment for stone cultural heritage, although many of them have been treated and restored over the past decade. This study approached the correlation between damage grade and the need of conservation treatment based on damage diagnosis of stone cultural heritage carried out from 2001 to 2005. The number of Third-graded (from First to Fifth-grade) stone heritage in deterioration was the highest among state-designated stone cultural heritage. The Fourth-graded stone cultural heritage (143 in total) was mostly influenced by high physiochemical deterioration, whereas the Fifth-graded ones (61 in total) was dominantly affected by biological colonization. It was estimated that total 211 stone cultural heritage were treated for conservation and restoration from 2002 to 2011. They were usually cleaned (total 134, 26.1%), joined and consolidated, and maintenance works as shelter construction, drainage installation and surrounding cleaning were carried out for some of them. The number of conservation intervention increased with the high deterioration grade, and the case number of metamorphic and sedimentary rocks. By age, the stone cultural heritage in Three-kingdom Period were treated the most, and other heritage in Unified Shilla, Goryeo and Joseon showed an approximate ratio. The stone cultural heritage fallen in the fifth-grade in deterioration demonstrated the highest ratio, approximately 80% of conservation intervention. These results can be used as preliminary data to define the emergency criteria for conservation intervention policy.

Conservation treatment of stone cultural properties in the open air is mainly conducted by companies specialized in conservation treatment. This study presents cases of conservation treatment of stone cultural properties housed outdoors in Seoul, including the Three-story Stone Pagoda at Nakseongdae in Gwanak-gu. The present condition of and damage to stone cultural properties are investigated and the materials and techniques used for conservation treatment are presented. The contamination on the surface of stone cultural properties located in downtown areas shows features specific to the related areas, meaning each case requires tailored conservation techniques. This study is expected to serve as reference for future conservation treatment of stone cultural properties in Seoul as well as others in museum collections exhibited outdoors. It is hoped that the cases presented in this study can become widely known to people in charge of conservation treatment in the private and public sectors to improve the quality of conservation treatment applied to stone cultural properties.

This study examined the applicability of deterioration monitoring techniques to establish efficient conservation and management system for stone cultural heritage which conservation treatment has been done. It was confirmed that deterioration mapping combined with photography and grid work, and adhesive tape test for the surface were very applicable to investigate the surface change due to deterioration, and assess the degree of granular disintegration quantitatively. The portable microscopic survey and ultrasonic measurement were efficient techniques to observe mineral looseness and microcrack, and to track the strength change of the stone before-and-after the conservation treatment. These techniques can be easily used by manage practitioners in the field through simple guidance and technical education. Also, it can contribute to build a long-term and methodical conservation and management system of the stone cultural heritage.

The forms of stone cultural properties vary depending on the purpose of construction. In general, pagodas and statues of the Buddha (including the Maebul) are representative of stone cultural properties and demonstrate important aspects of cultural history and scientific technology. The purpose for which cultural properties were constructed may influence construction technologies, so we must carefully think about and clearly understand the purpose of construction, namely the cultural and/or philosophical history, when conducting conservation treatments now. This may be examined through the relationship between "why?" and "how?": Why did the builders construct these stone cultural properties, and how did they use such technologies? We may be deeply impressed by the form and delicacy of the sculpture, which is the "how" aspect of the technologies, but we must also understand the effect of the "why." namely the soul and/or spirit of those who created the properties. The form of stone cultural properties may be influenced by (1) the political-social sphere, (2) religion, or (3) the cultural history of the period, which have changed over time. It is important that this is the view taken in current conservation treatment.

Stone cultural heritage will either be damaged by composite damage or will lose its original historical authenticity starting with the moment it is created. Various artificial interventions to restore them to their original state have been described, centering on the conservation treatment case of the Stupa of State Preceptor Jigwang from the Wonju Beopcheonsa Temple Site. Restoration of the Jigwang stone pagoda was carried out after securing all scientific and technological means for the research and protection of the cultural heritage in question. Since its restoration was promoted to retain its aesthetic and historical value and was based on a careful understanding of the original materials and prototypes, extensive restoration was sought, which contributed to the restoration of the original form, resulting in both preservation and authenticity.

The bisphenol A epoxy resin currently used for the conservation of stone cultural heritage items is known to suffer from yellowing discoloration. In order to mitigate this yellowing and explore the availability of more diverse materials for the conservation of stone cultural heritage items, a hydrogenated Bisphenol A-based epoxy resin was prepared and compared with the epoxy resin currently used in the conservation treatment of stone cultural heritage items. The newly prepared epoxy resin showed improved physical properties relative to the existing materials, especially in terms of tensile strength, adhesion, and machinability, while the yellowing discoloration was reduced by a factor of roughly five to eight. The results suggest that epoxy resin could be used as a stable material for the conservation treatment of stone cultural heritage items, most of which are located outdoors.

본 연구에서는 비측량용 디지털 비디오 카메라를 이용하여 석조문화재인 석탑을 대상으로 하여 촬영에 대한 오류를 사전에 검사할 수 있을 뿐만 아니라 재촬영을 하지 않도록 하였으며, 문화재 정밀 측량에 있어서 기대할 수 있는 양호한 정확도를 얻을 수 있었다. 차후 문화재 원형 보존에 대한 계획의 수행에 있어서 문화재에 대한 자세한 정보를 제공하기 위해 효율적이고 경제적인 방법을 제시하고자 한다.
