Recently, the use of fumigants for pest control of paper cultural heritages are limited because of the high toxicity of fumigants and the production of environment-harmfully compounds. Therefore, many non-chemical methods have been discussed and experimented. And it is recently focused on gamma radiation, which is one of non-chemical methods, for pest control of paper cultural heritage in Korea. In this paper, we carried out a gamma ray irradiation of papers including Hanji, copy paper, filter paper and then analyzed a physical properties and optical properties of paper sample to estimate the effect of gamma ray irradiation on paper properties. In result, gamma radiation have adverse effect on a physical properties and optical properties of paper, especially Hanji. Therefore, we have to carefully consider about using of gamma ray for pest control of paper cultural heritages.

The cultural properties of paper made from 11 to 16th century of the Kirimsa temple were found in Birozana Buddhist Statue which was made from 15 to 16th century. These have been stored and exhibited in the exhibition showcase. To examine the environment of conservation and the state of paper, we investigated the temperature and the relative humidity in the inside and outside of the Kirimsa museum and examined the external form and the internal state (water content, acidity and whiteness) of paper. During the investigation period from 27 Aug. to 30 Aug. 1997. The average of temperature and relative humidity were $28.2^{\circ}C$, 67% in the outside and $27.1^{\circ}C$, 73% in the inside, respectively. These indicated the air conditioning was wrong. Among the cultural properties of 79 papers stored in the Kirimsa museum, 37 cases had been repaired but 42 cases not. From the result examining the external form, 20 cases needed to repair. In the internal state of the cultural properties of paper, the water contents were from 11.9% to 16.5%, the average was 15.7%, the acidities from pH 5.7 to pH 6.2 and the whiteness from 37 to 45. From these results, we could see the cultural properties of paper stored in the Kirimsa museum was damaged by the several factors (hydrolysis by fungi, repeated elongation and retraction of cellulose) caused mainly by the high temperature and relative humidity. Therefore, for the conservation of the cultural properties of paper stored in the Kirimsa museum, it need to control the temperature at $18~20^{\circ}C$ and the relative humidity at $55\pm5%$ by the appropriate air conditioning. In order to sterilize fungi occurred to the surface of paper, the cultural properties of paper needed to fumigate. The fungi occurred on the surface of paper were wiped out by using of 70%solution dissolved thymol in ethyl alcohol.

Paper cultural heritages usually experienced the chemical and the physical deterioration because of various factors including preservation environment and the property of their materials. General restoration technology for paper cultural heritages is the lining. The application of the lining paper and the lining technology has varied depending on researcher's experiences. Therefore, each lining material and technology must be evaluated to develop a standard guide for preservation and restoration of paper cultural heritages. To date, various analysis techniques using lining paper, in terms of their materials, have been applied to analyses of causes and condition of damages, but it is difficult to develop a standard restoration treatment method of paper cultural heritages because it varies by their material. The Hanf, is made frrr the mulberry, is generally used for the lining in Korea.edt is required that the cr, in terms properties and general properties of Hanf, is used for lining papers, are evaluated to develop a standard guide for their restoration.ed this study, the general properties of several lining papers(Hanf), especially dimensave bility, were evaluated as part of the standardization of lining papers. The result have varied depending on the pulping chemical and the manufacturers. the basis weight, thickness and tensale strength of lining papers is bigger the paper treated by natural ash than the paper treated by sodium carbonate.ed case of formation, folding endurance, and dimensave bility, the paper treated by sodium carbonate showed better properties than those of the paper treated by natural ash.

Paper cultural heritages experience chemical and physical deterioration due to various factors including preservation environments and the property of paper materials1). Thus, it is important to develop optimal preservation and restoration methods for the damaged paper cultural heritages. Currently, lining is a popular treatment for the restoration of paper cultural heritages in Korea. Since lining paper is a layer of paper directly attached to the inside of cultural heritages for protection, understanding of the preservation properties of lining paper is primarily needed in order to devise the better preservation methods. The main material of lining paper is the paper mulberry, but additives such as chalk and white clay is sometimes used to enhance the preservation properties of lining paper. To date, the properties of the functional lining paper containing these additives have been not fully understood yet. In this study, dry heating aging at $105^{\circ}C$ and biological aging by the Aspergillus versicolor and Penicillium polonicum for the lining paper, which is made from paper mulberry and the chalk, are carried out to evaluate changes in their preservation properties by these aging factors. As a result, it is found that the functional lining paper containing 25.1% of chalk can control the growth of fungi, while the paper containing 32.7% of chalk do not show any protection effect. However, the functional lining paper added by chalk is more aged than the lining paper made from paper mulberry by dry heating accelerated aging.

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.

최근 우리 문화유산에 대한 관심과 그 연구는 종래의 관련연구자 뿐만 아니라 일반인의 참여가 높으며 그 범위도 국내에 한정치 않고, 국외 한국문화재에 대한 환수와 그 활용에 이어지고 있는 상황이다. 따라서 국외 소재 한국문화재 모두가 환수대상이라는 종래의 개념 이외에 다각적이고 적극적인 활용방안을 모색할 단계로 보고 이를 위해서는 유출경위 등 체계적인 현지조사를 통한 명확한 현황파악이 선생될 필요가 있다는 것이 이 논문의 출발이자 기본요지이다. 또한 국외소재 한국문화재를 좀 더 확장하여 유연하게 바라볼 수 있는 우리의 인식 전환 역시 필요한 시점이다. 이런 견지에서 한국문화재는 원래 생산국인 우리의 고유한 문화유산일 뿐만 아니라 인류가 공동으로 보호하고 활용할 인류의 보편적 가치(Outstanding universal value)가 있는 세계유산이라는 접근을 통해 그 활용의 폭도 넓혀질 수 있을 것이다. 이런 견해에 입각하여 미국 보스톤박물관 등 3개국의 대표적인 주요소장처의 한국문화재에 대하여 그 가치와 성격, 그리고 유출배경의 유형을 살펴 정리하였다. 본 논문은 위와 같은 인식의 바탕에서 향후에도 국외 한국문화재의 현지조사를 통해 유출배경의 명확성을 확보함으로써 학문적 연구는 물론 환수대상 혹은 홍보대상 들을 구분하여 정책기초 자료로 응용될 수 있도록 국외소재문화재 자료를 규명하자는 데 그 뜻이 있다.

Unlike traditional cultural assets, industrial assets are closely tied with contemporary life in numerous ways, and have acted as a bridge between the traditional architectural buildings and contemporary architectural buildings, reflecting the overall economical, social and cultural portraits of that time. Reinvestigating them in a new light, granting just and fair values, and preserving and transmitting these modern cultural heritages is a method of preserving the historical and cultural traditions in order to keep own identity and integrity. Nowadays, however, due to various sprawling developments and new development-oriented urban policies, only a select few industrial assets are being protected, the rest facing demolition and damages. In order to better cope with such situation, Korea has officially introduced the Registered Cultural Properties System since 2001, and began acknowledging the historical values of industrial buildings as modern cultural properties. By systematic analysis and deduction of characteristics from successfully recycled precedents such Oberhausen Gasometer in the state of Nordhein-Westfalen that have been preserved and recycled as cultural spaces, this paper aims to find and propose suggestions to rehabilitate and recycle the industrial cultural properties in Korea.

In the Nordrhein-Westfalen, Germany, there are approximately 3,500 industrial buildings under the cultural asset protection and management not only in the Ruhr-region but also state-wide. Unlike traditional cultural assets, industrial assets are closely tied with contemporary life in numerous ways, and have acted as a bridge between the traditional architectural buildings and contemporary architectural buildings, reflecting the overall economical, social and cultural portraits of that time. Reinvestigating them in a new light, granting just and fair values, and preserving and transmitting these modern cultural heritages is a method of preserving the historical and cultural traditions in order to keep own identity and integrity. Nowadays, however, due to various sprawling developments and new development-oriented urban policies, only a select few industrial assets are being protected, the rest facing demolition and damages. In order to better cope with such situation, Korea has officially introduced the Registered Cultural Properties System since 2001, and began acknowledging the historical values of industrial buildings as modern cultural properties. By systematic analysis and deduction of characteristics from successfully recycled precedents such Kueppers Mills at the Innenhafen Duisburg in the state of Nordrhein-Westfalen that have been preserved and recycled as cultural spaces, this paper aims to find and propose suggestions to rehabilitate and recycle the industrial cultural properties in Korea.
