Sumuk drawings are made with water and muk(墨), which are used to express the light, shade and texture of an object. The expression methods of oriental drawing can be divided into three methods: pictorialization, abstractness and realism. The method of pictorialization expresses traditional pictures or letters. Abstractness show an artist's aesthetic feeling through sprinkling, splashing and spreading diffusion of muk. The method of realism is Takbon which makes a copy painting directly from a monument by rubbing a paper with ink. Modern fashion designer attempts to develop a new Sumuk technique based on both oriental drawing style and western watercolor painting style. Rather than following the designated styles of oriental drawings and Korean drawings, new Sumuk technique colors detailed structures expressed as outlines, dots and lines or creates abstract patterns through spreading or spilling in showing theme of flowers, plants and insects. In this study, in order to develop fashion cultural products with Sumuk technique, rubbed copy of the ancient 'Emile bell Takbon' was used. For this study, with the combination of different colors and the patterns from 'Emile bell Takbon', designs for scarfs, shirts and one-piece dresses were created. These techniques enabled to express soft and strong Takbon image in simple Sumuk technique in harmony with modern trends.

This research examines embroidery panels of Hwarot belonging to the Victoria and Albert Museum (the V&A). There are a total of seven objects and are all disassembled into clothe pieces. They were classified into two groups according to their acquisition year. One group, four objects, was acquired by the Museum in 1920. Considering their materials, embroidery threads, techniques and formative characteristics of patterns, it can be assumed that the objects formed an original dress, Hwarot. Although they look very similar to the embroidery patterns of Hwarot belonging to National Folklore Museum of Korea, they are more finely embroidered with very thin embroidery thread that uses the Jarisu technique. There are some differences in used embroidery threads and embroidery skills between Hwarot artifacts of the National Museum of Korea and the V&A. The embroidery of the National Museum of Korea used thicker threads and longer (approximately 0.7cm) Jarisu stitch techniques. With these details, they would have been made in different time periods. Comparison of the V&A and Changdeok Palace' Hwarot objects show that their patterns' motifs are almost similar but the pattern units, expressions and embroidery techniques are different. Regarding the colors of their patterns, it is noticeable that the peonies are generally expressed in reddish and the lotus patterns are expressed in either bluish or purplish color. It seems that they are contrasted with red-colored flowers and show harmony between yin and yang symbolically. Three artifacts of another group were acquired in 1925. Two of them show patterns almost the same as those of the sleeves of Hwarot (no.33156, no.33158) in Chicago Field Museum collection. The pattern of the remaining object is very similar to Hansam of Hwarot (no.33158).

Submicron-sized polymeric colloidal particles can self assemble into 3-dimensional (3D) opal structure which is a useful template for photonic crystal. Narrowly dispersed polymer microspheres can be synthesized by emulsion polymerization in water using water-soluble radical initiator. In this report, we demonstrate a facile and reproducible emulsion polymerization method to prepare various polymeric microspheres within 200 - 400 nm size ranges which can be utilized as colloidal photonic crystal template. By controlling the amount of monomer and surfactant, monodisperse polymer colloids of polystyrene (PS) and acrylates with various sizes were successfully prepared without complicated synthetic procedures. Such polymer colloids self-assembled into 3D opal structure exhibiting bright colors by reflection of visible light. The colloidal particles and the resulting opal structures were rigorously characterized, and the wavelength of the structural color from the colloidal crystal was confirmed to have quantitative relationship with the size of constituting colloidal particles as predicted by Bragg equation. The tunability of the structural color was achieved not only by varying the particle size but also by infiltration of the colloidal crystal with liquids having different refractive indices.

Colloidal cadmium telluride (CdTe) quantum dots (QDs) and their nanoparticles have been synthesized by one pot sonochemical reactions under multibubble sonoluminescence (MBSL) conditions, which are quite mild and facile compared to other typical high temperature solution-based methods. For a typical reaction, $CdCl_2$ and tellurium powder with hexadecylamine and trioctylphosphine/trioctylphosphineoxide (TOP/TOPO) as a dispersant were sonicated in toluene solvent at 20 KHz and a power of 220W for 5-40 min at 60 $^{\circ}C$. The sizes of CdTe particles, in a very wide size range from 2 nm-30 ${\mu}m$, were controllable by varying the sonicating and thermal heating conditions. The prepared CdTe QDs show different colors from pale yellow to dark brown and corresponding photoluminescence properties due mainly to the quantum confinement effect. The CdTe nanoparticles of about 20 nm in average were found to have band gap of 1.53 eV, which is the most optimally matched band gap to solar spectrum.

Purpose - Pleasing ambient colors, music, scent, layout and salespeople are hypothesized to positively impact shoppers' perceptions about the atmosphere of a store. Few studies on the interactive effect of these atmospheric factors have earlier been undertaken. This paper looks at the interactive effect of color on the other predictor variables. Research design, data, and methodology - This study is from field locations in the shopping malls located in Delhi NCR. A descriptive study was undertaken to decipher the interactive effect of color with music, scent, layout and salespeople. Moderation of color on music, scent, layout and salespeople is regressed on store atmospherics. The authors investigate the effects of color, light, music, scent, layout and salespeople on store atmospherics in a retail context. They also study the interactive effect of color with predictor variables which significantly influence the perception of store atmospherics. Results - The paper reveals that music, scent, layout and salespeople influence customer's perception about store atmospherics. The interactive effect of color with scent, layout and sales people influence customer's perception about store atmospherics significantly. It does not moderate with layout and music. Conclusions - Store color is important in predicting store atmospherics. Care is needed to ensure that the effects of different environmental stimuli match.

This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$-6) content was negatively correlated (r=-0.217＊) with linolenic acid($\omega$-3) content.

The denim fashion is a style of clothing showing trends towards globalization in that it is most favored and most frequently purchased and worn by youngsters throughout the world. However, it differs from region to region in its shapes, colors, silhouettes and coordination, reflecting a feature of regionalism. Male denim fashion data were collected from large cities of the East and the West for an analysis in terms of design and coordination. It was found that a common point originated from the features of the clothing itself as well as from a common culture shared among those of similar ages while differences came from various factors such as aesthetic sentiments and lifestyle of each ethnic group, willingness to accept the fashion trends, and the ways of expressing oneself by means of clothing and their attitude towards clothing. It was noteworthy that the denim fashion in Europe and America, Beijing and Seoul differed largely owing to their different tastes for expressing themselves. A comparison study of the regional denim styles may lead to a better understanding of a worldwide phenomenon of the common fashion trends and regional differences in aesthetic appeal and the fashion preference.

This study investigated the optical characterization of water types based on Jerlov's classification, employing the CIE colorimetric system. Digital visualization techniques were applied to articulate watercolor manifestations intuitively. The L^* luminance parameter exhibited a discernible reduction from optical water type I III and from type 1 to 9, registering a range between 66 and 84. Analysis of color attributes in each optical water type revealed that in the transition from type I to III, the color a^* values spanned from -7.43 to -8.32, while color b^* values ranged from -2.97 to -3.33. a^* values for optical water types 1 to 9 varied between -6.28 and -10.50, with corresponding b^* values ranging from -2.51 to -4.20. Consequently, optical water type I, IA, IB, II, and III were discretely categorized by independent color values, as were optical water types 1, 3, 5, 7, and 9. The digitized representation of watercolor in this inquiry facilitated comprehensive information asso,o;atopm. The study highlights limitations in Jerlov's classification for representing watercolors in different ocean conditions. It emphasized the need to collect color data from various marine areas and formulate a novel color standard or method for comparing colors.

칼라도플러 초음파에서 요로결석의 종류에 따라 트윈클링 허상의 발생정도에 차이가 있는지 알아보고자 하였다. 색이 다른 두 종류의 요로결석에 대하여 물탱크에서 트윈클링 허상의 발생정도를 비교하고 결석의 표면과 성분을 분석하였다. 결석의 표면상태는 갈색의 결석에서 과립형 요철이 두드러져 보였다. 트윈클링 허상은 흰색의 결석에서 음향음영의 일부를 차지하는 1등급이 갈색의 결석에서 음향음영의 전체를 차지하는 2등급이 나타났다. 결석의 성분은 탄소와 산소를 제외한 칼슘과 인의 함유량이 가장 높게 나타났다. 결석성분 중 인의 함유량이 높을수록 결석표면이 매끄러우며 트윈클링 허상이 짧게 나타났다. 초음파검사로서 결석의 성분을 예측하기 위한 단편적인 역할을 기대할 수 있을 것이며 이는 결과적으로 치료계획에 도움이 된다.
