  • The bast fiber of Paper mulberry has been generally used as a fibrous raw material in traditional Hanji-making. Nowadays, its uses is expanded to different special purposes such as paper mulberry yarn, laminated paper, antimicrobial paper depending on its application. Despite the wide array of the use of mulberry fibers, it is still limited due to some difficulties in the automation process of manufacturing works. This study is focused on the analysis of chemical components and morphological properties of paper mulberry bark for the automation of bark peeling process. The bast tissue of paper mulberry was separated in three plies; black outer layer, green inner layer, and white inner layer. The total lignin content, holocelluloses, extractives and ashes, and the anatomical structure of the three layers in mulberry bark tissue were investigated. The analysis showed that the black outer layer is composed of about 50% of total lignin content, whereas the white inner layer is composed of about 90% of holocellulose content.

  • Today We have three full series of the annals of Joseon Dynasty. Taebaeksan volume which is one of them shows comparatively good maintenance but Taebaeksan volume also decomposed in patches. The size of cover and inner paper were increased in late Joseon Dynasty, but the weight, thickness and basis weight bears no relation to each other. The oxidation index of paper in annals of pre-periods of King Sunjo shows very high value. After the annals of King Sunjo, the oxidation index of paper is very similar to today's Hanji. L.a.b values of inner paper in the Taebaeksan volume are similar generally. The average length of fiber using image analysis soft ware is 8.08~9.92 mm, that like immediate value of measurement. The air fraction of fiber's range is 1.20~2.12%. It lower than today's Hanji. After considering the factors of the length of fiber, air fraction and FE-SEM, we reached that no difference between raw material of inner paper in the Taebaeksan volume.

  • The writing brush, ink stick, paper, and ink stone were the four precious things of the studying and recording in oriental world until even nowaday. The oriental paper was comparatively well evaluated in many papers and reviews, but it is difficult to find some scientific reports or reviews about the ink stick. In this paper, the scientific aspect of ink sticks of oriental maine three country(Korea, China, Japan) were evaluated by the physical, chemical and microscopic analysis. The result could summarized as fellows; 1. The Korean lampblack ink stick contains more carbon and less nitrogen and the Chinese ink sticks contain less carbon and more oxygen. 2. The Korean lampblack and cowhide glue contain relatively higher amount of sulphur. 3. The particle size distribution of carbon in the ink stick was not change after grinding in the ink stone. 4. The particle size of carbon and the pore size in the charcoal ink sticks of three country were larger than those of the lampblack ink sticks. 5. The ink solution of the charcoal ink sticks shows high roundness on Hanji while the ink solution of the lampblack ink sticks is spread readily to Hanji surface. 6. The change of whiteness in printing of the ink sticks is notable in thermal treatment.

  • The purpose of this study is to find out what the implications for communication in the Untacted era are through interpretation of works created by researchers for communication and relationship using traditional Hanji materials as a new communication method to cope with the situation of Corona 19. This work uses an in-depth interpretation of the motivations, intentions, and meanings of researchers who are challenged with their experience, knowledge, and intuitive insights. The works and interpretations that were originally exhibited for the purpose of human relations and communication using Hanji materials representing traditional Korean beauty are as follows. First, creative activities that utilize traditional materials for human relations and communication through overcoming the limitations of the untact era, such as Corona 19, are helpful for mutual understanding and finding meaning. Second, the use of traditional materials for the formation of relationships and communication between people in the same ethnicity, language, and space can be a medium for forming a common perception. The findings will provide motivation for the use and expansion of human relationships and communication in disaster situations as basic data.

  • This research were aimed at developing starches which have high preservability and high bonding strength from corn starch, modified cationic and oxidized corn starches, as compared to the fermented wheat starch. On the lining that attaching the base paper on the back of the work with paste, the coating weight was determined by the solid contents of the paste rather than the viscosity of paste. Adhesive strength and stiffness were also determined by the solid contents of the paste. Corn starch had lower solid contents, higher viscosity, and higher adhesive strength than other starches. In the iodine stain to the surface of peeled base paper off, paste deeply penetrated into the traditional Hanji than modern Hanji. And oxidized starch paste deeply penetrated into the paper layer than the cationic starch.

  • The purpose of this study was to investigate the functional properties of Changhoji with natural dyeing. This research would provide a basic information for interior material Changhoji. To estimate functional properties of super eight colors Changhoji, water staining, lightfastness, and floodlight color test were executed. In term of the water staining test, blue color showed the clear and other colors showed the little spot. As a result of measuring the lightfastness, Magenta color dyed with sappanwood showed the worst. But blue color dyed with indigo and Turquoise color dyed with indigo and Pagoda tree flower showed the highest. As a result of floodlight color test was no difference between sample color and floodlight color.
