After manufacturing the natural dyed actual size Hanji using 11 kinds of plant natural dyeing materials and 2 kinds of animal natural dyeing materials, the color characteristics and color change and color fastness after post-mordanting were compared and discussed. The hues of 13 types of natural dyed Hanji were black, PB, and RP, each with 1 type, YP with 3 types, and Y with 7 types. Among the natural dyeing materials, Chinese ink, indigo and Lac showed high color yield and color difference, and violet-root cromwell and gardenia seeds showed low color yield. The color fastness of Hanji dyed with turpentine diluted Ottchil, Pagoda tree seeds, Chinese ink and indigo was excellent, while that of gardenia seeds and violet-root cromwell were very poor. After post-mordanting of natural dyed Hanji with Al, Cu, and Fe mordants, the hue changes were show up the Alnus firma, clove, lac and cochineal. In addition, the color difference was very diverse and was overall the most biggest due to Fe mordant. After 72 hr. of UV irradiation on post-mordanting natural dyed Hanji, hue change was observed in 3 types and color fastness was improved in 8 types by post-mordanting. The Hue and color fastness are significantly different depending on the type of natural dying materials and post-mordants. Therefore, when dyeing Hanji with natural dyes, it is necessary to dye with sufficient knowledges and informations about the desired color and fastness.

The fruit color characteristics and persisting period of deciduous woody landscape plants were investigated through the field survey in Suwon region from January 1, 1992 to March 20, 1993. The summary of the study results was as follows; The total fruit color persisting period was about 320 days from May 1, 1992 when Prunus mume was beginning of fruit coloring, to March 20, 1993 when the fruits of Platanus occidentalis and platanus X acerifolia were persisting. And the plants of fruit persisting period over 60 days after leaf falling were Vibumum erosum, Ilex serrata, Ilex verticillata 'Christmas Cheer', Platanus X acerifolia, Platanus occidentalis, Berberis thunbergii 'Atropupurea', Ligustrum obtusifolium. According to the KBS standard color number, 52.6% of of the fruit color were red, 18.9% yellow, 11.6% black, green 9.5%, white 2.1%, violet 1.1%, and red is followed black 4.2%. Evodia daniellii, Ilex verticillata 'Christmas Cheer', Ilex serrata, Ginkgo biloba, Lindera obtusiloba, and Lindera erythrocarpa should be planted male and female species together for fruits. We got the new information on the fruit color characteritics and persisting period of Malus 'Hopa', Malus 'Almey', Malus 'Pioneer X', Acer rubrum, Malus prunifolia, Pyrus serotina, Berberis thunbergii 'Atropurpurea', Vibumum rhytidophyllum, Rosa spp. Vitis vinifera, Vaccinium angustifolium, Ilex verticillata 'Christmas Cheer', Magnolia stellata, Aronia arbutifolia, Sorbus alnifolia, Lonicera japonica var. aueroreticulta, and Ligustrum X vicaryi. And we need to introduce new cultivars of woody landscape plants including Malus spp, Berberis spp, Sorbus alnifolia yellow autumn leaf clone etc. for the better planting design. The fruit persisting period of woody landscape plants studied by fruit name was that sorosis 276 days, samara 155 days, legume 153 days, hip 133 days, pome was 124 days, drupe 92 days, berry 73 days, capsule 67 days, follicle 55 days and nut 52 days respectively.

Objective: Extension and Agouti loci play a key role for proportions of eumelanin and pheomelanin in determining coat color in several species, including goat. Mongolian goats exhibit diverse types of coat color phenotypes. In this study, investigation of the melanocortin 1 receptor (MC1R) coding region in different coat colors in Mongolian goats was performed to ascertain the presence of the extension allele. Methods: A total of 105 goat samples representing three goat breeds were collected for this study from middle Mongolia. A 938 base pair (bp) long coding region of the MC1R gene was sequenced for three different breeds with different coat colors (Gobi Gurwan Saikhan: complete black, Zalaa Jinstiin Tsagaan: complete white, Mongolian native goat: admixture of different of coat colors). The genotypes of these goats were obtained from analyzing and comparing the sequencing results. Results: A total of seven haplotypes defined by five substitution were identified. The five single nucleotide polymorphisms included two synonymous mutations (c.183C>T and c.489G>A) and three missense (non-synonymous) mutations (c.676A>G, c.748T>G, and c.770T>A). Comparison of genotypes frequencies of two common missense mutions using chi-sqaure ($x^2$) test revealed significant differences between coat color groups (p<0.001). A logistic regression analysis additionally suggested highly significant association between genotypes and variation of black versus white uniform combination. Alternatively, most investigated goats (60.4%) belonged to H2 (TGAGT) haplotype. Conclusion: According to the findings obtained in this study on the investigated coat colors, mutations in MC1R gene may have the crucial role for determining eumelanin and pheomelanin phenotypes. Due to the complication of coat color phenotype, more detailed investigation needed.

A color halftoning is the process of generating halftone images for the different color plans, for example, cyan, magenta, yellow, and black for a offset printing device. A conventional halftone technique, so called AM screening, is simple and easy to implement, but the halftoned dot patterns by using this method is not free for the moire` fringe. Moire` patterns are caused the power spectrum distribution on low spatial frequency domain. To avoid Moire` patterns, the conventional screen require the different screen angles for each color plans. Recently, Ultra-fine and 7 color printing methods are developed to expend the color gamut. In 7 color printing method must be used the halftone technique of random and blue noise characteristic to avoid Moire` fringe.
