The annals of Joseon Dynasty is the most valuable resource containing the record of Korean history and has been known as one of the UNESCO's Memory of the World Register. In some period, wax-treated paper was used in the annals of Joseon Dynasty to prevent the damage from pests. But, wax-treated volumes were discolored to brown, white or black, and partially cracked by the stiffened wax. It means that wax-treated volumes were damaged by the hardening and oxidizing of wax. The wax is considered as the first reason in damages on the wax-treated volume. Therefore, in this study we analysed the oxidation index of Korea traditional paper(Hanji) which is used as the restoration paper of the waxed volume in the annals of Joseon Dynasty by using FT-IR. As the analysis of FT-IR, the traditional two-layed stamping paper (Hanji sample F), which was treated by starch in its surface, was shown the most stable state after the accelerated ageing test.

For the purpose of reproduction of traditional gold thread, the artifact investigation was organized for 70 cases (109 pieces) of relics from Korea, China and Japan. In most cases, the main backside material of gold thread from Korea was the bast fibers from paper mulberry. In this study, the optimum sheet-making of Hanji for gold thread reproduction was tried by controlling several process factors of Hanji such as the cooking and beating time of paper mulberry fibers, the number of sheet-making ply, and converting method (Dochim). Tensile index, folding endurance and compressive strength of Hanji showed differences according to the correlation between cooking and beating time, and application of converting method (Dochim), while bending stiffness fell with decrease of thickness. These results can be applied to consider manufacturing factors to make Hanji for the production of gold thread.

We carried out cationization of Dak pulp (paper mulberry bast fiber pulp) which is raw material of Hanji (Traditional Korean Paper) using a (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride to improve dyeability during a dyeing of Hanji with Gardenia (Gardenia jasminoides) and smoke tree (Cotinus coggygria). Fiber specific charge densities were determined using polyelectrolyte titration method and K/S values of dyed Hanji was calculated by Kubelka-Munk equation. As the result, fiber specific charge density increased with degree of cationization. Colors of Hanji dyed with Gardenia did not vary significantly with degree of cationization, but cationized Hanji dyed with smoke tree showed a large increase of a* value and reddish yellow color. After-mordanting did not decrease K/S value of dyes with cationized Hanji. K/S values of dyed Hanji decreased with increasing dyeing temperature. For smoke tree, the cationization impair lightfastness of dyed Hanji without mordant. After-mordanting with copper acetate or iron chloride improved lightfastness of dyed Hanji.

Hanji(Korean traditional paper) is a valuable cultural heritage highly praised, even to this date, for its importance and technology by craftsmanship of our ancestors; it is a product of a combination of craftsmanship, well-established technologies, natural paper mulberry fiber and eco-friendly and durable natural materials and mucilages. Origin of the word 'Hanji(Korean traditional paper)' is from handmade paper made of bast part of the paper mulberry; as paper manufacturing with paper machines introduced in Japan was adopted in late Joseon, paper produced previously was called 'Hanji' and paper produced with western machines was called 'Yangji(machine made paper)'. Hanji has been called by many different names and used in various ways according to materials and production methods; and the functions varied. Hanji, from the era of three states to Joseon era, has been praised for its unique and excellent quality in three Asian countries(Korea, China and Japan); its unique excellence continues to this date in many paper-related national cultural heritages. Also total of 11 cases are registered to UNESCO Memory of the World for its importance, 8 of which are associated with traditional Korean paper: Hunminjeongeum, the Annals of the Joseon Dynasty, Jikjisimcheyojeol, Seungjeongwon Ilgi, the Royal Protocols of the Joseon Dynasty, Donguibogam, Ilseongnok and A War Diary. To examine excellent characteristics of conservation science in Hanji, many studies have been developed. By developing analysis and manufacturing technologies, the excellence of our Hanji should be re-verified scientifically and the tradition should continue as one of the representative Korean cultural heritages.

Jeonji technique was widely used in general Hanji handicraft including Jihwa handicraft. But the technique itself has not been passed on. By contrast, Jiseung technique and Jiho technique have been passed on and continuously developed. And although the Huji technique has not been transmitted, it should be vigorously used as a technique of producing the frame in order to revive the authenticity of traditional Hanji handicraft. Jumchi technique, a method of using water to connect between layers, is an effective technique of diversely expressing the feel of materials of Hanji craftworks. Modern Hanji handicraft has used the characteristics of paper and paperboard diversely produced nowadays as much as possible, which shows that it is more likely to develop as handicraft.

This study was carried out to investigate the papermaking characteristics of paper mulberry(Broussonetia kazinoki) for new Korean traditional paper(Hanji). Hanji has been traditionally made only with the bast fiber of paper mulberry. Besides mulberry bast part, wood core was utilized separately or in mixed forms as raw materials for the new Hanji. Hanjis made from the solfomethylated pulp were shown higher brightness and sheet strengths than those from alkali and alkali-hydrogen peroxide pulps. The brightness of solfomethylated pulp was found to be high enough not to need additional bleaching. In the physical properties of the Hanjis mixed with bast part and wood core pulps, the handsheet strengths were decreased as the increase of the wood core pulp contents. But the sheet strengths of Hanjis containing 10∼30% of wood core pulps were higher than those of the Hanji containing bast part pulp only. The sheet formations were improved as the increase of wood core pulp contents, while the sheet strengths were decreased.

This study was carried out to investigate the making method and properties of Hanji(Korean traditional paper) for wallpaper for the purpose of mass production and mass consumption of Hanji. Paper mulberry fiber was longer than wood fiber in length and it had also much extractives and ash in content. Bast fiber was a little damaged in the fibrilation and beating process because it was weak in flexibility and compressive properties. Proper conditions for making two-ply and three-ply Hanji were examined and six kinds of Hanji were made on the basis of the three-ply paper making method. The sample OH(Original Hanji) 2-2 and OH 3-2 among them obtained good results in quality test by appearance from wallpaper makers.

This research is implemented to shed new light on the essence of Korean sentiments, aesthetic sense and restructure it in modern ways. In particular, applying the current images of traditional Korean village in Jeonju to neckties is focused on the purpose of globalizing the industrialization of Korean traditional sceneries and Korean image products. Adobe Photoshop CS program was used to develop necktie designs containing the images of the traditional Korean village. To make artworks, the Digital Textile Printing System that is an environment-friendly printing method was used. Moreover, Hanji yarn fabric was adopted for them so as to use Korean materials. The total number of developed designs is eight and neckties for men were made by altering images of the traditional Korean village in modern ways. According to the research results, required are more investment and self-development for proper understandings on our traditional cultural images and their development from now on. Moreover, in my view, customers' desires must be met by comprehending public consciousness, trends and environments to meet customer's desires. Furthermore, higher value-added products must be created by using Hanji yarn and images of traditional Korean villages by distributing high quality designs that will satisfy customers' desires and psychology, producing small quantities of products with various designs and colors.

Stage costumes are characterized by the importance as a medium of total visual expression on a synthetic art and need to be designed more effectively. This study followed the stage costumes of the play 'Long long time ago whuo-ee whuoee' which participated in the China-Japan-Korea University Theatre Festival. By consisting of the framework of a Korean story that tells and expands the visual expression province by the access method of a producer, the unique costume in the play was created by the dyeing of the traditional hangi. First, the use of hanji in theater represents originality and a fresh variation with the formative beauty of stage costumes in accordance with hanji that conforms to the recreation of tradition. Second, the dip dyeing technique made it possible to express colors limitlessly and the airbrush dyeing technique along with dyeing twice could account for the weak points of the color. As a result, the color brought effect as expected. Third, the weak points were supported by a Jumchi technique that created the fibroid material tangled with stronger adhesion in the creation of a hangi costume. In addition, dyed hangi was attached to the outer fabric. It allowed the costume to have a unique texture that was both soft and tough. This enforced the visualization of the costume and durability to prevent possible damage by the performers. Forth, pieces of hanji were attached to the damaged parts of the costume after re-visiting the dress rehearsal. As a result, the stage costumes represented the shabby clothes that express the social class of the characters. A new understanding of the excellence of traditional hanji was found and confirmed the possibility of it as a material for stage costumes through the study.
