  • The annals of Joseon Dynasty designated as a national treasure No. 151 and a UNESCO World Memory are among the greatest archives that should be preserved permanently and inherited to future generations through the proven scientific conservation method. The annals of Joseon Dynasty in the custody of the National Archives of Korea as the sole original archive, has been restricted from the direct physical and chemical approaches. In this study, it is to develop a systematic conservation management scheme, based on the conservation state of the annals. Four books from the annals were selected out of 848 books and their moisture contents and optical property profiles were measured through the books. All the defects previously and newly found were pictured in 10~100 magnifications. The wire marks left on the Hanji's of the annals were analyzed. It was found that water damages and paper molds were prevalent in all four annals selected, and it was recommended to conduct more research for the conservation of those damaged areas. It turned out that various qualities of Hanji's were used for the time of publishing the annals because moisture content, optical properties, and wire mark intervals were quite different between papers even within one book.

  • Since early times, paper has been the leading means of expression in human civilization. Along with the development of languages, people have used paper as their major intermediation measures to flourish the culture. At this point of time when studies in latest design are various and abundant, these fixed ideas on paper should be eliminated first for inventive thinking and freedom of expression. Because breaking the established notion helps to diversify the function of paper. We can see furniture made of paper come in useful to our ancestors in their daily life with the development of "Hanjiquot;. Each piece of paper furniture had its own function and beauty depending on processing method. Not only has been used for materials of basic modeling in the process of modern furniture designing, paper has also been used for the main material for the purpose of a new trial. If we try to find out the ways to take diverse characteristics of paper and develop them, while overcoming the defects of the material, paper has great potentiality for many kinds of use in furniture industry.

  • This studies were carried out in order to develope environmentally-friendly fiber materials and substitute resources of Paper mulberry. Various plant fibers such as New Zealand flax, Indian mallow, Kuzu vine and Yucca were used as raw materials of hand-made papers. We rotted these 4 kinds of plant fibers and removed non-cellulose. After rotting, the pulping rate(%) and the length of fibers in pulps were measured. The physical characteristics of papers made of various plants fiber were investigated and the probabilities of practical use were considered. The results were as follow: The non-cellulose contents of plant fibers were 30403040 and those contents must be lower down to 8% to be able to manufacture the hand made papers. The lignin in pulps were removed almost and the hemicellulose were partially removed to reach up to appropriate level of the pulp rates and fiber lengths. The more hemicellulose removed, the finer fiber thickness were and rapidly the lower Hanji tensile strength were. But the tear strength of these plants of hand-made papers do not decreased so much as tensile strength. So the property of 4 types of plant fibers might be of great advantages to make hand-made papers. Both tensile and tear strengths of Hanji of New Zealand flax, Indian mallow, Kuzu vine and Yucca were higher than Paper mulberry hand-made paper. When 30% of mulberry paper were mixed, the mixing effect showed maximum. Because of the functions of all plant fiber hand-made papers showed better than those of Paper mulberry hand-made paper, 4 types of plant fibers could be substitute Paper mulberry.

  • The National Museum of Korea has a collection of various materials. In particular, items made from organic materials such as wood, paper, and leather are vulnerable to the influence of insects and germs, requiring fumigation as well as pesticides and bactericides. The influence of pesticides and bactericides on the change in dyed paper was examined by applying the oddy test used to confirm the toxicity of various materials used in museums. Results revealed that the products of B and H companies had the least influence on the change in dyed paper. On the other hand, the result of the examination of cochineal and curcuma dyed paper revealed a significant change in the control group compared to the one exposed together with dyed paper, probably because of humidity rather than the sample.

  • This study was conducted to investigate the effect of the strengthening treatment of methyl cellulose (MC) on properties and aging characteristics of the dewaxed papers during humid heating aging. Beeswax-treated Hanji was dewaxed by the supercritical fluid extraction method, and subsequently the strengthening treatment was performed with MCs having three different viscosities. MC was first applied by dipping a dewaxed paper into a MC solution whose concentration was controlled from 0.5% to 1.5%. After the strengthened papers were artificially aged at 80C80C and 65% RH, the changes in optical and mechanical properties of the samples were evaluated. The results show that viscosity and especially pick-up of MC influenced the strengthening efficiency and aging characteristics of dewaxed paper. Strength was increased with the MC coating weight; in addition, strengthening with MC improved preservability of the dewaxed paper. The optimum conditions for the strengthening with MC was found to be the coating ratio of 4% with 1500 cP MC.
