우리 주변에는 세월의 무게를 견디지 못하고 나날이 훼손되어 가는 문화재가 많다. 온도변화에 따른 팽창계수의 차이나 풍화작용 등으로 유물 일부가 떨어져 나가고, 표면의 균열 부분으로 물이 스며들면서 얼어붙었던 부분이 녹아 구조 불균형이 발생하기도 한다. 또 산성비나 대기오염과 같은 환경오염으로 산화 문제가 발생하는가 하면, 비둘기 등 조류 배설물이나 세균류 지의류 이끼류 같은 생물학적 요인으로 파손되기도 한다. 종교나 예술 활동에 따른 인위적인 훼손(반달리즘, Vandalism)도 일어난다. 자연재해로 어쩔 수 없이 사라지는 문화재도 있다. 불에 타 한 줌의 재로 변한 양양의 낙산사가 그 대표적인 예다. 낙산사는 8년 7개월의 복원 작업을 거쳐 되살아났다. 그래도 '낙산사'하면 '불'이 먼저 떠오르는 것은 천년고찰의 화재가 우리에게 상처로 남아 있기 때문이 아닐까. 한편 어렵게 발굴했지만 이미 때를 놓쳐 위기에 처한 소중한 문화재도 있다. 2009년에 발굴된 전북 익산시 미륵사지 석탑의 사리장엄구(사리를 봉안하는 일체의 장치)에 들어 있던 유리병은, 오랜 세월 공기 속의 수분이 풍화작용을 일으켜 두께가 얇아진 데다 0.04mm라는 수백 개의 미세한 조각으로 부서져 복원이 어려운 상태이다. 워낙 두께가 얇아진 탓에 살짝만 압력을 받아도 부서지기 쉬워 접합 자체가 불가능하다.

This thesis is a study on the properties of new religious ritual dress in Korea to help understand new religions more completely. A new religion means 'Newly born religions'and it is an opposite conception of the existing religion. The new religions in Korea have been established, changed and become extinct beginning with 'Dong-Hak'movement by Choi Jea Woo in 1860. Sometimes they've caused social problems with their number increasing after the rapid industrialization in 1970's. There are about 350 new religions and 2,000,000 christians in Korea now. Some of theme are pseudo religions wearing the mask of religion and also there are great new religions that will contribute to our spiritual history. The latter shows the thoughtful properties of the union of religion, postnatal creation, nation's independence, and human's centralization. There are properties of pluralism, nation's independence, symbolism, and thoughts in a new religious ritul dress.

The stone pagoda on the Miruksa temple site has a high value as architectural history, because this stone pagoda is one of the oldest and grandest stone pagodas which remain in Korea today. However, this stone pagoda has remained only six stones of the northeastern part, becased this stone pagoda was collapsed at past. Therefore, it is important to know the original structure and form of this stone pagoda. Hypotheses about collapse cause of this stone pagoda are presented as four cases: collapse by earthquake, collapse by fragility of ground, collapse by durability reduction, and collapse by lightning, On the basis of these four collapse hypotheses in this study, we investigate collapse phenomenon through the structural analysis using discrete element method and evaluate collapse causes of this stone pagoda.

Au-Cu alloyed coating layer were found by Hg-amalgam process and it seemed to be used Cu-amalgam process similar to Au-amalgam. Coated layer is dense and unique, Thickness of layer was 1.5 to $18.0\mum$ which had 95.3 to 99.8% purity of gold Matrix metal mostly cosists of forged copper alloy which had high purity and ferrite ($\alpha$) strusture. It showed excellent refining technical level at that time. Aowever, the nail, ferrous matrix used for strength needed, composed of silver foil packed and gold layer for adherence between ferrous matrix and gold layer

The stone pagoda of Mireuk temple site is currently restoring through the repairing process. This stone pagoda has the various construction types in the inner and outer space. Therefore, the stress concentration and structural behavior need to be considered through the analysis of various construction patterns. To this end, this study presents the structural modelling and analysis considering the discrete element analysis technique to solve the discontinuum behavior between the stone elements. Also, this study performs the structural performance evaluation through the various design variables for the safety of stone pagoda. Through the analysis results, we can find out the small stress concentration in the several members. But, because the stresses and displacements are relatively small, we can secure the safety of the whole structure.

The Standing Buddha Statue in the Gwanchoksa temple consists of medium to coarse grained biotite granodiorite with dark grey color, and it has a week gneissosity along the pegmatite veins. The results of magnetic susceptibility and geochemical patterns of the host rock of Standing Buddha Statue and the basement rock suggest that both values are formed from the co-genetic magma with the same differentiation process. The CIAs of the basement rock and the Standing Buddha Statue are calculated to 51.43 and 50.86, and the WPIs are estimated 4.52 and 8.95, respectively. So the weathering potential from the host rock of Standing Buddha Statue and basement rock prove to be high. The Standing Buddha Statue is terribly damaged with physical weathering from deterioration and exfoliation, and are scattered with secondary pollutant and precipitate. Basement rock is also in danger of ground collapse because of irregularly developed discontinuity system. Most surface of Standing Buddha Statue is seriously discolored into yellowish brown and dark gray, or black precipitates are also formed. Moreover, it is heavily covered with crustose lichen, fungi and algae, or moss are also found. In order to control the influential factors with the complex deterioration of Standing Buddha Statue, it is needed to rearrange a site environments, and conservation scientific management is required to protect it from covering lichens, exfoliations and fractures.

The Mireuksaji stone pagoda of the Iksan was built in Muwang King of Baekjae Kingdom and has maintained its present status through several rebuilding process. Recently, the structural unbalance of the pagoda has worsened, so for scientific maintenance recovery of its original pagoda form, the pagoda is under dismantling process. The original form of this pagoda is being presumed to be a plane square pagoda of nine stories, though only a portion of six stories remains until today. The destroyed part from collapse was liked in insecure pagoda form by Japanese in year of 1915. On the surface of the stone which has gone through the present time, efflorescence appeared as precipitation substance over crusted and due to this phenomenon, the structure and color of thee original stone haven't been preserved. Therefore, quantitative analysis on its kind, emitted status and contamination type of secondary inorganic contamination substance of the over crusted surface were analyzed. Also through reaction experiments, contamination type was defined and tests have been applied to find the requirements that will wash out the contaminants. The result of this study will provide the base of quantitative analysis on the kind of inorganic contamination of the surface of stone assets, and it shall also contribute to the application of scientific maintenance recovery of surface cleaner for efflorescence.

This study evaluates the occurrences, phyfical weathering and biological deterioration on rock properties during the dissection process an object of stone pagoda in the Mireuksaji temple site. For restoration and conservation, all kinds of rock properties are carried out detailed scientific investigation and diagnosis. Constituting rocks of the pagoda composed mainly of equi-granular medium grained biotite that rock properties presumed to be use about 3,000 materials. Main external properties of the pagoda are total 446 materials, and the rock properties under the concentration load on the each floors occurred with overlapping fracture, weathering and deteriorations. The 84 materials show highly degraded about $18.8\%$ among the external properties. Representative physicochemical deteriorations are fracture, loss, break, exfoliation, degradation, grain shaped dissolution, relief surface, discoloration and hydroxide precipitates, in this study, the deterioration state of each properties give a precisely description and analysis. Coverage of lichen and algae on the rock surface represented about $85\%$. As the some properties, biological contaminants withered up when spray rock surface with diluted cleaning chemicals. Results of the study are utilized an application for restoration system and detailed investigation during the dissection process of stone cultural properties.
