The plastic optical fiber has been previously known to have the limits in fabrication and care, due to its lack of flexibility and durability. Recently, an innovative technology of 'water-resistant & flexible optical fiber', in which the surface of etched POF(i.e., plastic optical fiber) is to be coated with a type of synthetic resin, has been developed. In this study, the post-treated POF-based flexible textiles were evaluated in terms of luminance, physical visibility and perceived visibility, according to the fabric lengths and colors of the light source. The POF-based flexible textile with 10cm fabric length and green light source appeared to show relatively higher illuminating effects. The maximum distance for perceived visibility of the POF-based flexible textiles was found to be 100m. Therefore, the results of this study are expected to be utilized as a fundamental for the further studies to develop the digital color clothing with application of POF-based flexible textile.

The sensibility effects of color combinations was studied utilizing tone on tone combination and tone in tone combination. A total of 24 color combinations were rated by 10 college students using Semantic Differential Method. The data was analyzed by using Excel statistics program 2004. Analysis method was factor analysis. Theresults of this study were as follow. Color combinations utilizing tone on tone and color combinations utilizing tone in tone was evaluated a very different impression. Thus these were found to have an influence on sensibility effects of color combinations. In comparison with appearance of color combination using colored paper and that of product to apply to color combination using colored paper, it was showed to be evaluated mostly similar impression. However By characteristic with product, shape, size and texture, appearance of color combination is likely to be evaluated very difference impression. The results of these studies will serve as a basis of color combination image or color design.

This study was conducted to grasp distribution of native plants in flower market and uses of native plants in floral decoration. This study was investigated native plants sold in flower market(2017.01-2017.12) and their monthly sales. Also, this study analyzed the use of native plants, frequency of native plants classified by form and color of native plants used for floral decoration in flower magazines 'Fleur' and 'The Flower'. Among 172 species distributed cut-flower, native plants in Korea flower market are only 24 species(14.0%). Number of filler flower(15 species) is more than other forms. Native plants used in 'Fleur' and 'The Flower' were 14 species(10.2%) and 17 species(9.6%), it is meaning that native plants were less used than foreign plants. The number of filler flower was the highest in both magazines, but form flower(299 works) in 'Fleur' and mass flower(571 works) in 'The Flower' are used most frequently. According to color analysis of native plants used for floral decoration, P(purple), PB(navy) and RP(reddish purple) were 57% of the total. It can be increased native plants uses in flower decoration with developing form and mass flower considering color preference.

Users of KakaoTalk emoticons use Kakao Talk emoticons as means of communicating their emotions in virtual space. Emotional state is represented by design element (auxiliary, color, form, motion) and storytelling element contained in emoticons. The purpose of this study is to investigate the factors of the storytelling and design elements of kakaoTalk emoticons and how they prefer the kakaoTalk emoticons as emotional expression means. In terms of storytelling, crocodiles, peaches, dogs, ducks, lions, moles, and rabbits were made up of ordinary fruits and animals. Most of the emoticons are composed of stories with unique personality, and each story has a complex one by one, which makes it easy for users to approach and use them. In terms of design, I used various auxiliary elements (flame, sweat, tears, runny nose, angry eyes, etc.) to express angry, sincere, nervous, begging, joy, and sadness. The color elements consisted of most of the warm color series with the unique colors (green, red, yellow, pink, white, black, brown, etc.) of emoticon characters regardless of feelings of joy, anger, sadness, pleasure. The form factor is composed of a round shape when expressing factors such as joy and sadness. On the other hand, when FRODO and NEO express sadness and anger, they represent the shape of a rectangle. The motion elements are horizontal, vertical, and oblique expressions of APPEACH, NEO, TUBE, and JAY-G, expressing emotional expressions of sadness, anger, and pleasure. APEACH, TUBE, MUZI & / Shows the dynamic impression of the oblique and the radiation / back / forward / rotation. The anger of TUBE and FRODO shows horizontal / vertical / diagonal and radial motion. As a result of this study, storytelling is structured in accordance with each emoticon character. In terms of design, auxiliary elements such as flame, sweat, and tears are represented by images. The color elements used the unique colors of the character series regardless of the difference of emotion. The form factor represented various movements for each emotion expression. These findings will contribute to the development of communication, emotional design and industrial aspects. Despite the significance of the above paper, I would like to point out that the analysis framework of the storytelling and the semiotic analysis of the supplementary elements are not considered as limitations of the study.

In this study we investigated emotional characteristics of various whites which have slightly different nuances to suggest guidelines that help designers to select appropriate colors when designing white based products. The study involved three different procedures. In experiment 1, we selected 20 emotional words through a survey (N=30) among 60 words, which we picked from literature review that was thought to be appropriate to evaluate product colors. In experiment 2, we evaluated the emotional characteristics of 13 basic colors from the I.R.I Hue & Tone 120 system (N=30) using previously selected emotional words, to find relative emotional positions of white in comparison to other colors. Based on the ratings, factor analysis was conducted and consequently four factors were extracted: flamboyant, elegant, clear, and soft. Accordingly, the emotional characteristics of the 13 colors were profiled and compared with those of white. Finally, in experiment 3, we conducted an evaluation of emotional characteristics on 25 whites with different nuances facilitating the four factors obtained in experiment 2. The color stimuli used in experiments were measured in terms of CIE 1976 $L^*a^*b^*$, and regression analysis was performed in order to predict the emotional characteristics through the L, a, and b values of a color, as long as that is perceived as a white. Throughout three empirical studies, we observed three overruling tendencies : First, there are four important factors when evaluating product color - flamboyant, elegance, clearness and softness; second, white is dominantly the most elegant in comparison to other colors; third, the emotional factors of the study were affected by some combinations of attributes of colors rather than by all three-hue, saturation and brightness. In addition, the equations derived from the regression analysis in experiment 3, it is expected that designers may predict the emotional distinction between nuances of white.

Recently, the importance of cultural design has been increasing due to the globalization. However the cultural design is mainly focusing on the shape or color stereotype of different cultures, ignoring another important aspects of cultural design: the way of peoples' interacting with product. The study aims to develop usability test program for cultural user-interface design that operates in the world wide web. The study begins with discussing the nature of culture through defining culture and reviewing the depth and variables of culture. Based on the findings the structure of the usability testing program on the WWW design methods is identified. The usability testing program on the WWW comprises of five different modules: module for identifying users' demographic characteristics, module for cultural variables, module for population stereotype, module for usability testing, and module for data storage and analysis. Finally findings are summarized and further research prospects are outlined.

Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices.
