An analysis of the components of clay mineral before and after coloration (XRF) showed that the elements involved in coloration are Fe, Cr, and Ni. Fe accounts for 65% of coloring components on dyed fabric; in addition, Cr and Ni also affect coloring. The optimal coloration condition was to repeat the process of immersing the cotton fabric in $80^{\circ}C$ slurry of 8g of clay mineral to 1g cotton for 60 minutes, dry it for 24 hours and rinse three times. Especially, as the repetition of coloration increased, the $(K/S)_{440}$ value of sample A increased from 1.0 to 2.5, and sample B increased from 1.0 to 1.6. The effect of the repeated process on coloration was significant; consequently, the rinsing and drying process were important to decrease the coloration level. It also showed excellent results in regard to color fastness to washing, light, rubbing, perspiration, and antibiotic effect.

This paper examines the way that the principles of coloration for Hoecha(繪次) and Sucha(繡次) were applied for shoe making in ancient China and Korea. Hoecha is the principle of drawing, and Sucha is the principle of embroidery. Hoecha and Sucha is the application principle of the five colors(五方色) from the five elements(五行: metal, wood, water, fire, and earth). Hoecha matchs a color with the opposite side color, and Sucha matchs a color with the beside color. A shoe consists of Sinul(body of shoe) and ornaments attached to it. According to the ratings of shoes, Hoecha and Sucha were differently applied for coloration of Sinul and its ornaments. In general, shoes were classified into Seok and Gu. For Seok, which was the high-ranked shoes, Hoecha was applied, while Sucha was applied to Gu, the low ranked shoe. As Hoecha was originally a principle of coloration for patterns on tops(jacket. 上衣), it was applied to the high ranked shoes i.e., Seok. Also, as Sucha was a principle of coloration for patterns on bottoms(skirt. 下裳), it was applied to the low ranked shoes i.e., Gu. Thus, black was decorated on red Seok, blue on white Seok, red on black Seok, yellow on hyeon(玄: a kind of black color) Seok, and white on blue Seok, all of which were applications of the principle of Hoecha. As the application of the principle of Hoecha to Seok was also done for red Seok for males and females in late Joseon, and red Seok for the crown prince in the period of the Korean Empire, black decorations were used for red Sinul. However, for blue Seok, worn by females in the period of the Korean Empire where Ming's systems prevailed, black decorations were used, which was an application of Sucha. Though there had been no discrimination between genders in the application of Hoecha and Sucha originally, the low ranked principle of coloration was applied to Seok for females.

The purpose of this study is to investigate the coloration characteristics by identifying the factor affecting red coloration of copper red glaze in traditional Korean ceramics. This study analyzed the characteristics of the reduction-fired copper red glaze by using XRD, Raman spectroscopy, EDX and UV-vis spectroscopy. As a result of XRD analysis, the glaze completely melted and amorphous glass appeared overall, and the characteristic peak of metal Cu was shown together. In addition, as a result of Raman analysis, the characteristic bands of CuO and $Cu_2O$ were shown together. The distribution of component elements was observed by EDX. As a result, copper(Cu) were distributed throughout the glaze. Thus, it was shown that copper red glaze appeared the best red coloration because metal Cu, CuO and $Cu_2O$ evenly existed throughout glaze in particle colloidal state. The chroma value of the copper red glaze was CIE $L^*$ 30.07, $a^*$ 13.65, $b^*$ 3.72. Wine-Red Solution was shown by Dark Graish Red coloration.

Color harmony of Moon and Spencer is based on the Munsell color harmony theory. This harmony theory is established in the three of harmony and disharmony, the harmony of the area of effect, and Aesthetic Measure of harmony and disharmony. Aesthetic Measure here is how to obtain the quantitative expression of the degree of harmony. American scholar Burkhoff were analyzed with the proposition that beauty of Moon-Spencer is with the order in complexity. In this paper, the good and bad of coloration was divide elements of the order and the complexity. Aesthetic Measure is divided into elements of the complexity from elements of the order. This is utilized in the calculation shown in the various image, problem of color harmony and disharmony, which is treated as a sensibility was calculated by numerically. Thus Aesthetic Measure show was good or bad coloration by determining the color in the various image.

The purpose of this study is to obtain basic materials to complement the 'time series table serving' by analyzing external color elements. We selected traditional Korean restaurants in two five-star hotels and two famous traditional Korean style restaurants and analyzed their colors and the coloration of the Korean table settings. The results are as follows. By using strong luminosity contrast, restaurant A made its customer focus on the food and used red as the principal point (highlighted) color. Desserts, which have small dimensions, were served in 'Buncheong' ware with 'bakji' method, which has strong contrast; this broke the color balance. The use of small patterned dishes with 'johwa' method would achieve color harmony. Restaurant B used a stronger color for the tables than the foods, making the point color inconspicuous. Lowering the brightness and saturation of the table color would be beneficial. In restaurant C, thick green napkins provided the point color, making the atmosphere of the restaurant dull and dark and interfering with the overall bright atmosphere of the restaurant. Using lower saturation, high luminosity, and yellowish colors would bring harmony to the overall atmosphere. In restaurant D, the point colors were divided into three groups; their diversification during the entire course of the meal made the flow of the meal more natural. However, the use of the violet color, which gives a cold feeling, in the middle of the meal courses broke the overall flow of warm color in the meal. Considering the already-present contrast between red and green, it would be better not to use the violet chrysanthemum in the course of the meal. As mentioned above, there are several issues in terms of the color arrangement, the usage of table pads, and the natural flow of colors. Those issues indicate the necessity for an overall plan for the banquet table set-up in terms of color.

Knifing parameters specially related to lint generation in the knitting zone such as knitting needles, yarn feed angle and yarn feed speed were investigated with a developed test rig, which simulated the hutting area on the knitting machine. Three different types of needle counts and feeding angles affected tension and the amount of lint that was caused by frictional forces between the yarn and the morphological structure of the needle. However, the yarn feed speed did not affect the lint generation. The results implied that a more advanced test rig was necessary for further study. Also, chemical and mechanical modifications of the kilting elements may be necessary to improve the lint problem.

Polymerization of tetraethoxysilane on a glass substrate was investigated by remote microwave plasma using argon with portions of nitrous oxide as carrier gas. Transparent layer like a thickness of 0.5 ${\mu}m$ 3 ${\mu}m$ were obtained, differing in chemical composition, depending on plasma power and treatment time as well as on ageing time. In general the milder the treatment and the shorter the ageing was, the higher was the content of organic structural elements in the layer. We have identified that the chemical structure of our samples composed of mainly Si O and Si C groups containing aliphatics, carbonyl groups. These results were obtained by X ray photon spectroscopy, Fourier transformed infrared spectroscopy, and scanning electron microscope combined with Energy dispersive X ray spectroscopy.

Effects of passive film quality by chemical passivation and solution flow on the corrosion behavior of 304 stainless steel in HCl solution were investigated using a coloration indicator, and by corrosion weight loss, electrochemical polarization and element dissolution measurements. A high redness degree suggests a low passive-film integrity for 304 stainless steel following air exposure, while the minimum redness degree for the samples after chemical passivation suggests a high passive-film integrity. In the static condition, samples subjected to air exposure exhibited a high corrosion rate and preferential dissolution of Fe. Chemical passivation inhibited the corrosion rate due to the intrinsically high structural integrity of the passive film and high concentrations of Cr-rich oxides and hydroxide. Solution flow accelerated corrosion by promoting both the anodic dissolution reaction and the cathodic reaction. Solution flow also altered the preferential dissolution to fast uniform dissolution of metal elements.

The Yakhyeon catholic church (Historic Site No. 252 in Korea) that was constructed in 1892 has been the first western brick structure to ever have existed and one of the most important historical materials in the Korean modern architecture. After a fire had broken out at the catholic church in 1998, the stained glass on the back wall, the slab glass (dalle de verre) introduced by Lee Nam Guy in 1974, was repaired in 1999 because of singe scorch and water leakage. An analysis of the coloration elements showed that yellow, red and green included Zn, K and Cd, respectively. The glass of red contained Se, dark green contained Mn and Cr, and blue contained Pb and S. According to material analysis, the masonry joint was identified dolomite ($CaMg(CO_3)_2$) and calcite ($CaCO_3$), which was observed plate, columnar, rhombic and square of crystalline particles. Meanwhile, ultrasonic velocity in the stained glass recorded low speed in the middle and lower right of the window (an average of 4,130 m/s). And the joint was measured the lowest physical properties of the top left and middle of the window (an average of 2,053 m/s). This study have showed that extensive physical damage was founded to the left and middle rather than the right side. In this respect, more research in needed to conserve the correlation between color and physical properties.

The Ac (activator) which is one of the well-characterized transposable elements from maize was examined for its transposition possibility to the heterologous plant (P.nigra x maximowiczii) genome via Agrobacterium tumefacience (LBA4404) mediated transformation system. A number of transgenic plants were successfully recovered after 30 weeks by amount reduction from 50 to 15 g/$m\ell$ kanamycin for in vitro selection to minimize phytotoxic effects and to increase callus growth and regeneration efficiency. Among transgenic plants, 62 out of 106 transgenic poplars (58.5%) showed abnormal phenotypes such as severe serrated leaves and light leaf coloration. Indigo staining with X-gluc proved indirectly the restoration of Gus enzyme function and the presence of Ac in poplar genome by PCR. Southern analysis indicated the transposition and existence of Ac element in poplar genomes. In this research, an Agrobacterium-mediated transformation system in poplar species was developed and identified that Ac derived from maize can be excised and trans posed into other poplar genomes.
