Korean Paintings have been drawn on in the main two types of support material - paper and silk. In these things, silk designates picture silk, that of a specially weaved textile for painting since CHO-SUN dynasty, different such as hemp, ramie have been started to use for support material In addition to picture silk. However the structure of hemp and ramie are so close and progue, They are not proper to express the technique of pigments on the back of the paintings. On the other hand, picture silk is efficacious in pigments on the back of the painting with its interval between the strands and translucent textile. As the result, paintings on the silk has many - sided techniques as compared with painting on the papers therfore various devices in conservation have to be considered to deal with the techniques. In this report the focus is on classifying the method of removing the Lining paper according to the several types of expression technique of paintings on the silk.

Paper is easily damaged by physical and chemical deterioration under several factors. Damaged paper cultural heritage is usually restored by Lining. A traditional method of Lining is attaching the lining paper behind the original paper cultural heritage using starch and water. It supports the weakened quality of paper. In Japan, paper cultural heritage is restored with "Washi" which is made from mixture of Paper mulberry and Japanese cedar. In the west, the lining paper made from Paper mulberry, which has extraordinary excellent conservativeness, is usually used as a restoration material for paper. But Japanese Washi has dominated the demand for restoration materials as the most preferred restoration paper, and most kinds of paper made from Paper mullbery have been called as 'Japanese paper'. Result showed that the strength of the Korean lining papers was generally higher than that of the Japanese ones. As a result from measuring the rate of dimensional change after water-immersion and drying, sample B of the Korean lining papers and sample E of the Japanese lining papers showed the highest stability.

The modern philosophy of historic conservation focuses on the permanence of the material aspects of monuments as historic evidence of the artistic achievement of the past. However, so strongly are European attitudes to architecture and its conservation embedded in modern conservation, that it has skewed all conservation thinking towards the concept of the European-type monument which emphasizes visual beauty through its material substance. Thus, some basic ideas of modern conservation seem ill-suited to East Asian architecture which is conceived in a different spirit from its European counterpart. The purposes of the paper are to discuss the need for approaches which are different from the modern Western view of conservation for East Asian architectural heritage, and to make suggestions for developing conservation principles more suited to the unique values and aesthetic sense of East Asian culture and architecture. Conservation principles in the East Asian societies are determined in relation to the spiritual and naturalistic sensibilities of East Asian culture and architecture.

Seaweed extracts, namely carrageenan obtained from Grateloupia elliptica and algin obtained from Laminaria, were employed as adhesive agents to synthesize solid adhesives for paper. Carrageenan from Grateloupia elliptica with the highest adhesive strength and lgin from Laminaria with the highest compressive strength was selected. The selected carrageenan and algin were mixed in a ratio of 7:3, and the mixture was employed as an adhesive agent. At a high temperature, sodium stearate(used as a solidifying material) oxidized the seaweed extracts. Consequently, carrageenan and algin were added to the final manufacturing process. The adhesive strength of the final synthesized solid adhesive is found to be 3.02 MPa and the compressive strength is found to be 30.5 N. Compared to the adhesive strength (2.95 MPa) and compressive strength (30.11 N) of commercial solid adhesives, the obtained results indicate superior adhesion characteristics. Furthermore, the proposed adhesive is environment-friendly because the presence of volatile organic compounds, formaldehyde, and heavy metals(such as chromium, lead, and cadmium) were not detected. Moreover, when used, the flatness of paper was twice that of commercial solid paper adhesives. Hence, the proposed adhesive can provide excellent adhesion, stability, and usability.

The effects of sulfur dioxide on paper were investigated since these sulfur compounds could cause damages on cellulose and organic materials in papers. For the reason, exposure ageing tests were performed on traditional Korean paper (Hanji) and two different types of modern paper (acid-free and acid paper) to determine the damage with regard to the optical as well as physicochemical properties according to the varying $SO_2$ concentration. As a result, optical properties were not changed while physical and chemical peoperties were remarkably changed with the exposure period. In the case of pH, $SO_2$ had little impact on the pH of the Hanji and acid-free paper while the pH of acid paper was remarkably decreased. The decrease of the folding endurance of the Hanji was relatively smaller than those of the acid-free and acid paper. The results prove Hanji was more resistant to $SO_2$ than the modern paper in terms of optical, physical and chemical properties. In addition, it was also suggested that $SO_2$ concentration should be kept below 0.01 ppm for the preservation of paper objects.

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.

The purpose of this research was to identify causes of damage of wax-treated volume of "The Annals of the Joseon Dynasty". As one of the efficient restoration methods, analyses of damaged state of reproduced wax-treated paper through tests of degradation of wax-treated paper under an artificial setting were performed, and in particular, differences between lightness and acidity were observed. On the whole, it was confirmed that yellow wax-treated papers were more stable than white wax-treated papers against artificial aging treatment, which is thought to be because the white wax-treated paper was more affected by a variety of substances interacting with paper than yellow wax-treated paper under artificially aged conditions, which were added in the course of refinement and processing operation such as decolorization and deodorization.

국립중앙박물관에서는 "고려·조선의 대외교류전"을 대비하여 고지도, 고서, 고문서 등의 지류문화재에 대하여 보존처리를 실시하였다. 일반적으로 지류문화재는 자연적인 노화 외에도 온·습도, 빛, 물리적 힘 등의 여러 가지 주변 환경에 민감하게 반응하게 된다. 온·습도 변화에 의한 수축과 팽창, 유물에 직접적으로 가해지는 곤충·곰팡이 등에 의한 생물학적 손상, 그리고 인위적으로 행해지는 물리적 힘에 의한 손상 등이 그 대표적인 예일 것이다. 이번에 보존처리를 실시한 유물들에서도 그러한 손상들을 쉽게 확인할 수 있었다. 따라서 고서, 고문서 등의 보존처리 과정에서 볼 수 있었던 손상상태와 그 보존처리 내용, 그리고 지류문화재의 손상방지를 위한 간단한 응급처리 내용을 소개하고자 한다.
