In this study, as a fuel filter for automobiles, base paper which can filtrate the polluted particles must satisfy with the standards of each vehicle. and a filter of impregnation paper made that combining the base paper with the resin. Therefore, They were wanted to found out the factors that affect base paper and impregnation paper according to content of HPZ, Mulberry pulp(MP), Laub holze bleached kraft pulp(LBKP). The most important things we wanted to find out in base paper and impregnation paper test were weight, thickness, air permeability, burst and tensile strength, maximum pore size and mean pore size, stiffness. we wanted to measure a rate of change of these condition by adjusting a rate of mixing for HPZ, MP and LBKP. Moreover, It suited for an impregnation paper mixed with a rate of mulberry pulp 20%, HPZ 40% and LBKP 40%. Used resins in this study was Phenol, Acryl, PVAc. And as every resins, sample was divided into existence and nothing of embossing. as a fuel filter for automobiles, It was appeared that the suitable condition of base paper was a rate of mixing for HPZ(40%), MP(20%) and LBKP(40%).

The aim of this study is to develop Casual Hanbok design made of Hanji yarn textiles for New Silver generation women. The New silver generation is a coined word which has meaning of a newly silver generation and it is distinguished from pre-silver generation. New silver generation is a generation that is independent and given active role by their age groups and generational characteristic. The concept of silver generation was introduced from maturity market in Japan. This study was based on analysis about their preference of forms, colors, and materials of Casual Hanbok. The survey target were 270 female over age 50 living in Daejeon City. The analysis methods used frequency and percentage. The results were summarized as following. Although almost of them haven't worn Casual Hanbok, they had the positive recognition on wearing one. They preferred longer length jacket to traditional Korean style, shorter length of skirt. They also preferred the traditional sleeve shape and knotted buttons. On the foundation of this fact, 2 styles consist of 5 Casual Hanbok design items made of functional material - Hanji yarn textiles that have antimicrobial, deodorant, quick drying, far infrared radiation which are not harmful to health - for New silver women were suggested. One style was 3 items - blouse, vest, skirt - which are the sense of Korean tradition with activity by patch. The other was 2 items - jacket and skirt - which are the sense of Korean tradition with modern way by quilting. Lastly, these garments were evaluated by 13 experts, they were satisfied with 2 styles and all items. As this study were based on the Elderly women living in Daejeon city, it had the limitation on applying of preference styles to all the New silver generation.

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.

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.
