This study aims to develop colored gemstone products based on the analysis of color preference. Colored gem stones were classified by their colors using Munsell's ten basic colors and the color preference of women consumers in their twenties was analyzed, in consideration of trend analysis and design image description analysis, which led to the direction of product development. The analysis of color preference seems to suggest that consumers preferred blue quartz, cahnite, spessartite garnet, the colors of which are rather less known to ordinary consumers, to the other more common kinds of gem stones. Through the analysis of the trends and adjectives to describe preferable design images, the current study has made it possible to explore the designs for the future development of colored jewelry products, which would satisfy the consumption value and individual tastes of the consumers. It is expected that the current study may contribute to the jewelry industries and designers as a basic data for developing colored gem stone products.

The aim of this study is to figure out the preference features on design components of shop facade on the basis of the questionnaire survey on short-term memory and sensory memory of human right after an image experiment. As for a preceding research, this study examined the design features of facade into tangible elements and intangible elements, and also classified them into physical, aesthetical, marketing and symbolic components in detail. And, it extracted 5 representative elements in preceding studies including shape, material, pattern, color and sign, which is the standard of a questionnaire survey and preference analysis. The subjects of the experiment were 30 men and women who were over 20 years old majoring interior design. They were exposed to 20 images with 10 seconds respectively through a video, and were asked to respond the questionnaire promptly. The findings of preference analysis of design components of facade including shape, material, pattern, color and sign are as follows. Firstly, shape was the most interesting and attracting component, and designs applied with shape of objects such as 'web', 'drawer', 'wheel' and 'button' obtained high preference. Secondly, as for material, block, steel, exposed concrete board attracted higher preference as memorable materials than other materials. Material was affected by shape, pattern and color. Thirdly, pattern was the most lasting element. Designed pattern had higher preference than simple pattern. Fourthly, as for color, red and green with strong stimulation and attention attained priority having long lasting memory. Fifthly, when visiting a shop, sign out of 5 elements of shape, material, pattern, color and sign drew attention the most. As for the preference of location of sign, 'center top' was the most noticeable. The findings of this study could be utilized for facade design, and also could be used for commercialization considering highly preferred components, and top preference aspects of such elements. advised that to give an impression to customers is important to make a successful design for sales marketing, which, in turn, would lead customers to revisit the shop.

The purpose of this study was to investigate the perception and preference on textile design specially on bedding products which are widely interested in the life-style market. The study was carried out targeting to 250 women between the ages of 20s and 40s based on the four seasons. The collected data was processed with SPSS 21.0 program using frequency, cross tabulation, and ANOVA analysis. The results were as following. There were slight differences on the results of the study including purchase behavior and preferred bedding textile design: color, color tone, and pattern on the textile design of bedding products according to age and season. Most of age had similar color preference on the bedding products in the season but a slight different between fall and winter. However, as color tone and pattern on the textile design of the bedding products were concerned, there were significant difference between the age depending on the season. There were significant differences of color tones and patterns in fall and winter, but not significant in spring and summer. Therefore, the domestic market of the bedding products needs more various textile design development according to consumers' preference and seasonal trend which should be discriminated in order to increase product competitiveness.

The objective of this study was to compare the quality characteristics of chicken breast and thigh meat from North Korean native chickens (NKNC), South Korean native chickens (SKNC, woorimotdak), and commercial broilers (CB). NKNC thigh meat had a higher crude protein content than CB. In addition, the breasts of NKNC and CB had higher pH values than that of SKNC, but the cooking loss was higher in NKNC. The surface color of the breast and thigh meat of NKNC was darker and redder than that of SKNC and CB. The total collagen content of the breast and thigh muscles was the highest in NKNC, followed by SKNC and CB. A similar trend occurred with breast meat hardness. The content of arachidonic and docosahexaenoic acids was higher in both the breast and thigh muscles of NKNC than in those of the other groups, while the concentrations of linoleic and linolenic acids were higher only in thigh meat. Sensory evaluation did not show any differences among the three different strains of chicken except for the meat color. Sensory panelists preferred thigh meat from SKNC and CB to that of NKNC due to the strong dark color of the NKNC. Based on these results, NKNC had harder breasts based on texture, as well as a darker surface color and higher composition of long chain polyunsaturated fatty acids than CB. The quality characteristics of SKNC tested in this study were intermediate between NKNC and CB; however, SKNC may have a better chance of acceptance by Korean consumers due to the undesirable color of NKNC.

Stainless is widely used for various purposes due to its good corrosion resistance. There has been much research to produce the color stainless steel by several methods. In this experiment, TixN films have been deposited on the SUS304 substrate by the DC magnetron sputtering system and the color and texture of the films as a function of coating conditions has been studies. The TixN films showed a (111) preferred orintation in bias-free conditions. The texture of coated later was changed from (111) to (200) to (2200 with a change of the bias from -1000V to -3000V. When the bias is low, coated elements have low energy. Therefore, the texturct (111) of low surface energy. The mobility of atoms was increased with the increase of the blas and texture was changed to the other plane. Non-etched specimens all exhibited strong (111) texture. This result shows that (111) is a loose plane and of non-etched specimens all exhibited. High growing velocity of (111) of especially was main texture of Non-etched specimens. Low working pressure($4\times10^{-3}$torr) was more effective than figh working pressure ($6\times10^{-3}$torr) for the gold color of $Ti_xN$ film. L and b were increased and a was decreased with the increase of bias voltage. Accordingly, We obtained the near gold color of $Ti_xN$ film(L;92, a;1~1.5 b:24~29.50. As a result of reflectance. And as the bias increased, the reflectance was proportional to the increasing bias voltage, but we took the top reflectance when the bias voltage was -200V.

PURPOSE. The purpose of this study was to investigate the effects of surface treatments, liquids, and aging on color, translucency, and surface properties of monolithic ceramics. MATERIALS AND METHODS. Lithium disilicate (LDS) and zirconia-reinforced lithium silicate (ZLS) ceramics (n = 135 each) were cut and divided into three groups [crystallization+glaze (single stage), crystallization-glaze (two stages), and crystallization-polish (two stages)]. One sample from each group was examined using scanning electron microscopy (SEM). Remaining samples were divided into four subgroups (distilled water, coffee, grape juice, and smoothie) (n = 11 each), stored for 12 d in the respective liquids, and thermally aged. One sample from each subgroup was analyzed using SEM. The color, gloss, and roughness values of the samples were analyzed after surface treatment (initial) and storage under different liquids+aging conditions. The initial data and both the aged data and data change values were analyzed using robust two- and three-way analyses of variance. RESULTS. The glazed groups exhibited smoother surfaces. Ceramic type and ceramic-surface treatment interactions affected the initial translucency parameter (TP) (P < .001) and the initial and aged roughness values (P ≤ .001). Surface treatment type affected the color change (P < .001), and ceramic type affected the aged TP values (P < .001). Type of ceramic, surface treatment, and their interactions affected both the initial and aged gloss (P ≤ .001) and TP change values (P ≤ .015). Surface treatment type and ceramic-surface treatment interactions affected the gloss change values (P ≤ .001). CONCLUSION. Although both ceramics and all surface treatments are clinically applicable, crystallization-glaze is recommended. When gloss and smoothness are important or when translucency is important, ZLS or LDS may be preferred, respectively.

The purpose of this study is to comprehend the color and the coloration of Han-bok on the oil-painting of modern Korea. Generally, the modern Korean art is from late 19th to early 1980s' for the lowest year. Through the introduction of oil painting and the painter's work which had been reflected painter's realism at these times, we might know that the phases of the times and we could see a Korean costume and color combination. In this study, Han-bok is divided to upper clothes, lower clothes and the other parts which was distinguished by the color. The color of Han-bok which is watched on the modern art oil-painting is mainly white. The primary color including red, yellow, blue and middle tone colors is in harmony. It means that the five colors of Yin-Yang Wu-hsing were preferred until the modern times. The coloration of Han-bok is classified to a one-colored arrangement, two-colored arrangement and three-colored arrangement. The one-colored arrangement by white and black is a peculiar coloration to the modern times. The two-colored arrangement is a traditional coloration of Han-bok. The color which is high value and chroma is arranged on jacket, Jeogori. A dimension rate that is related with the difference of value and chroma made a visual harmony. In many cases of the two-colored arrangement of neutral colors is not much different in Jeogori and Chima. So Han-bok which is two-colored arrangement of neutral colors is colored in a breast- tie, pigtail ribbon, cuff and waist band for getting visual focus. The represented three-colored arrangement is white Jeogori and navy blue Chima with red breast-tie. It is a perfect visual color combination. The color of Han-bok was inherited a traditional color and the combination of neutral color was balanced. It was a refinable coloration system according to a difference of value and chroma. It means that a color sensation and arrangement of Korean have been developed by our unique climate, nations and the culture which has been formed for a long times.

Heat treatment of wood is an attractive alternative environmentally-friendly treatment to add value of less valuable woods by improving color, dimensional stability, and natural durability. To improve the color properties of Korean white pine (Pinus koraiensis) and royal paulownia (Pauwlonia tomentosa), we treated the woods at $160^{\circ}C$, $180^{\circ}C$, $200^{\circ}C$, and $220^{\circ}C$ for 2 hours. Color change after heat treatment was evaluated using the CIE-Lab color system and survey was conducted to determine the consumer preferences towards color of heat-treated wood. Lightness ($L^*$) decreased with increasing temperature and the higher degree of change was obtained in royal paulownia. The red/green chromaticity ($a^*$) in both wood decreased after heat treatment at $160^{\circ}C$, and constantly increased after heat treatment at $180^{\circ}C$ to $220^{\circ}C$. Yellow/blue chromaticity ($b^*$) in Korean white pine tended to increase after heat treatment at $160^{\circ}C$, then decreased gradually afterwards. In royal paulownia, $b^*$ values linearly increased with increasing temperature. Overall color change (${\Delta}E^*$) increased with increasing temperature with higher degree obtained in royal paulownia. Samples with the clamps in both wood species showed lower degree of the change in $L^*$, $a^*$, b and ${\Delta}E^*$. The results of the consumer preferences test showed that the darker colors of heat-treated woods were more preferred by consumers compared to the lighter colors of untreated woods. Consequently, heat treatment could enhance the color properties of Korean white pine and royal paulownia woods for value added products.

The purpose of this study was to develop a large representative data base for character goods marketing strategy. The study was to determine character name awareness in relation to segmented distribution regions and such demographic variables as sex and age. The author also analyzed preferred design. A total of 360 questionnaires were distributed and 359 reliable ones were used for statistical analysis. A SAS statistical package including frequency tables and Chi square test and factor analysis and Kendall′s relation analyses was used. The results are as follow : character name awareness involves "character name decognition" based on asking subjects to identify character names from 50 given names. "Tele-tubbies" was found to be a dominant commercial character name as a result of the recognition test, and "Sailer-moon" was found to be a dominant animation character goods as a result of the recognition test. Character recognition was significantly different in the segmented distribution legions, three age groups and different sex groups. People considered design first in purchasing any character goods, and they considered color second in purchasing them. The most favored part of garment far character to be stitch to was the center front in the T-shirt/dress shirt, the center back in the Jumper/jacket, back pocket in the trousers/skirt. The results of a Chi-square test showed that preferred part in the trousers/skirt of character was related with age variables.
