The philological consideration of Korean Buddhist Monk's robe and its reviving have been investigated in traditional way. The configuration and colour of Korean Buddhist monk's robes have been properly adapted for an period, territory, and atmospheric phenomena. In case of Korea, introduced Buddhism from China realize modern robe from under the influence of fusion of Chinese ornament culture and Korean traditional ornament culture. As a result of this modern robe has been consisted of a Buddhist monk's robe and a cope. The modem robes has been significantly affected by industrialization, contrary to ancient time taxed robes as public imposts. At present be familiar in mass production we have a preference for the easier way in making and even color forming. In this paper it is focused on dyeing part, which recognized its important in latest time, at first declined according to appearance of chemical dye, evaluated its convenience in use. That is, it is increased natural dye, people begin with recognition of difference of physical properties for dress dyed with chemical pigment and that with natural pigment. In consequence, I have presented that both making colour of gray using traditional method, and three demolished-color prescribed by Buddhist law. Of course, though it become generally know that dyeing of robes occupied significant part of traditional natural dyeing. But in case of religion, it also is important to know symbolical meaning involved in its colour. Most of Buddhism-believers or even Buddhists who actually be dress in robe are without knowing the meaning of colour, or its revealing method. There, I have considered mating three colour of demolished- color included blue, black, and red, and also represented dyeing method of Buddhist monk's robe using both charcoal and ink-spick. From religious font of view, as robes contains involving of blessing, I have an intention of improvement way in dyeing and succession and development of traditional culture through consideration of traditional dyeing method. And I have also intended to restoration the value of robe's colour, disappeared by the time. moreover, I have shown that dyeing with natural pigment is profitable for both environment and sanitary aspect.

Kim Whan-ki is an unusual instance in Korean modern artists, who payed attention to emotional and expressive effects of colors. The color of Whan-ki's paintings have been recognized as linked with 'blue' in spite that he used colors within the category of 'Colors of Five Directions(五方色)', which are traditional oriental colors composed of red, lue, yellow, white, green and black. Kim Whan-ki unearthed upon similarity of Five Directions Colors to the three(five) primary colors which modern abstract painter like Mondrian layed down. Whan-ki switched the five directions colors to modern ones. Kim Whan-ki's dot painting in which pure and watery color is sucked in ground is modernistic adaptation from ink painting. He packs a dot with sky and earth, moon and stars, forest and tree, birds and flowers, friends at his hometown, wind, sound and so on. Putting tens of thousands of these shapes and colors into a dot is modernistic version from ink painting. In that point there is a possibility to say that 'dark blue' of the dot painting is 'Hyun-saec(玄色)'. Eventually we can make sure that Kim Whan-ki's view of Art originated in oriental philosophy and beauty.

This study was carried out to investigate natural insectifuge materials from tree extractives in order to substitute for organic synthetic insecticides for food wrapping corrugated board. Tree samples were collected, extracted, fractionated with hexane, $CH_2Cl_2$, ethylacetate(EtOAc) and $H_2O$, and then freezed dried for further study. EtOAc or $H_2O$ fractions were chromatographed on a Sephadex LH-20 column for isolation and purification, and the isolated compounds were characterized by spectroscopic tools such as NMR and MS. Crude extractives of EtOAc and $H_2O$ fractions were added to the printing ink for corrugated board with the concentration of 2% or 3% based on the weight of the ink, then the prepared ink was printed on the corrugated board to be used for evasion test using larva of indian meal moth(Plodia interpunctella(Hubner)). Robtin, dihydrorobinetin and leucorobinetinidin were isolated from the wood extractives of black locust(Robinia pseudoacacia) and the bark of poplar(Populus alba $\times$ glandulosa) contained many kinds of compounds such as (+)-catechin, naringenin, aromadendrin, eriodictyol, sakuranetin and its glycoside, taxifolin, neosaturanin, salireposide, p-coumaric acid and aesculin. Much of (+)-catechin was isolated from the bark extractives of willow(Salix koreensis) in addition to (+)-gallocatechin and p-coumaric acid and the bark of weeping willow(Salix babylonica) also contained (+)-catechin, (+)-gallocatechin, dihydromyricetin and myricetin.

Conventional fingerprint powders used during crime scene investigations pose potential health hazards. Thus, multiple natural replacement powders, including squid ink powder, indigo and rice powder were used to develop (visualize) latent fingerprints on non-porous surfaces (e.g., glass, plastic and tile). Fingerprints developed using the natural powders were compared using the Automatic Fingerprint Identification System (AFIS) with those developed with traditional black powder. The peak areas of ridges were also compared using densitometric image analyses. Collectively, objective and quantitative evaluation methods were developed. The effectiveness of natural powders varied depending on the surface but, in general, squid ink powder performed well on most surfaces. Indigo powder performed well on tile surfaces, while rice powder performed well on glass surfaces. Plastic was the most difficult surface from which to develop fingerprints. Image analysis using Field Emission Scanning Electron Microscopy (SEM) demonstrated the importance of the size and shape of natural powder particles to properly adhere to the ridges. Although densitometric image analyses did not correlate the number of minutiae and ridge peak areas, an unbiased, objective evaluation method would be possible using image analyses with a reference image. Additional experimentation will yield safe and cost-effective natural powders with which adequate fingerprint development can be performed.

Electronic Ink is a stored data in the form of the handwritten text or the script without converting it into ASCII by handwritten recognition on the pen-based computers and Personal Digital Assistants(PDAs) for supporting natural and convenient data input. One of the most Important issue is to search the electronic ink in order to use it. We proposed and implemented a script matching algorithm for the electronic ink. Proposed matching algorithm separated the input stroke into a set of primitive stroke using the curvature of the stroke curve. After determining the type of separated strokes, it produced a stroke feature vector. And then it calculated the distance between the stroke feature vector of input strokes and one of strokes in the database using the dynamic programming technique. We did various experiments and our algorithm showed high matching rate over 97.7% for only the Korean script and 94% for the data mixed Korean with the Chinese character.

Recently, active movements are occurring to reestablish our own traditional Korean images in all levels of society. One of them is about Ordinary Hanbok. Academics and business sectors are endeavoring to develop comfortable and Korean traditional Hanbok designs and popularize them as well. Based on the facts, the study focuses on developing Ordinary Hanbok designs for women by applying Korean traditional patchwork in order to present handmade, humane senses. First of all, the backgrounds, history and preference of Ordinary Hanbok are discussed through literatures and precedent studies as study methodology. Then, the study is analyzing the formative beauty of Korean traditional patchwork that contains emotions of women in the Chosun Dynasty. After that, it shows Ordinary Hanbok designs developed for women by using checks, free style, and yeoiju patterns of the fabrics dyed with clay and Chinese ink that recently attract people in particular. The results are like followings; First, the limits that excessive transformation of Hanbok may cause the lack of traditional beauty can be covered through using a variety of images of Korean traditional patchwork. Second, diverse face configuration of patchworks has very unique geometric forms so to be easily applied to modern Ordinary Hanbok designs. Third, the sewing technique of patchworks also plays a role as a design factor as important as face configuration. Fourth, utilizing fabric pieces may result in various unplanned face configuration and help resource recycling. Fifth, it is possible to coordinate Hanbok with other ordinary clothes that people normally wear on. Sixth, using patchworks images can encourage developing more active and refined designs added with traditional beauty. Seventh, natural dying and fabrics are eco-friendly, which is good for human health and environment. Finally, more studies should be done on design development based on precedent studies about Ordinary Hanbok. Also, it is important to foster social atmosphere and circumstances where people accept wearing Ordinary Hanbok as our natural culture.

This study is aimed to a textile design with a motif of korean endemic plants and a method for printing it in an eco-friendly manner. The floral pattern with the motif of korean endemic plants was designed using Illustrator and Photoshop program. CMYK color, which is the basic color of Digital Textile Printing (DTP), is based on natural dyes, and various colors, achromatic colors and pastel tones are applied. As a result, half-linen and cotton were suitable as a result of designing and applying a floral pattern of a korean special plants. Also, as a result of analyzing the printing effect by colorway and DTP for each material, it was printed uniformly and the washing fastness was good. However, fastness of color change showed low, indicating that a follow-up study was needed. This study contributes to environmental conservation through eco-friendly printing and the korean endemic plants will be interested in people around the world beyond korea.

This study was undertaken to clarify the histopathological changes of pigs naturally infected with hog cholera. Microscopic observations of the brain as well as clinical observations were carried out for the naturally and experimentally infected pigs with hog cholera viruses. Electron microscopically the vascular cuffings of the brain were also observed in the experiment. In addition, clinical and pathological studios were carried out in the rabbits inoculated with ALD, lapinized and isolated strain of hog cholera virus, respectively. The results obtained are as follows; Vascular cuffing of the brain was observed in about 97% of the natural cases and all of the experimental cases. Among the 496 cuffed blood vessels of natural cases, intramural cuffing (82.9%), intramural and perivascular cuffing (11.9%) and perivascular cuffing (5.2%) were seen, respectively. Electron microscopic findings on cuffed blood vessels of the brain were endothelial cellular degeneration, intramural separation and vacuolation, perivascular vacuolation and infiltration of pleomorphic lymphoid cells. In the rabbits dosed with tissue suspension of the lymphoid organs and isolated hog cholera virus, high body temperature and vascular cuffing of the brain were observed, meanwhile these changes were more significant in pre-injected cased with indian ink.
