The purpose of this study was to examine the visual evaluation of image according to the style, hue, value, and chroma of the male clothing and the preference of image. A quasi-experimental method was used for this study. The first factorial design was the $2{\times}3{\times}2{\times}2$ (style of upper clothes ${\times}$ hue ${\times}$ chroma ${\times}$ color of trousers), and the second factorial design was the $2{\times}3{\times}2$ (style of upper clothes ${\times}$ value ${\times}$ color of trousers). The styles of upper clothes were a soutien collar casual jacket and a polo shirt. The subjects were 509 female college students living in Seoul. Factor analysis showed five image categories of men's clothing: initiative, dignity, politeness, activity, and mildness. Yellow was evaluated as having the highest initiative and activity. Blue was shown to have lower mildness than red and yellow. The high saturated chroma was perceived to be higher initiative and activity than low chroma. The shirts were evaluated higher in activity and mildness than the casual jackets were. The beige pants were perceived to be higher in dignity and mildness than the dark blue pants. The high chroma jackets were perceived to be higher in both initiative and activity than the low chroma jackets. The navy blue pants with the upper clothes in low chroma blue were perceived to be higher in politeness than with the upper clothes in low chroma red or yellow. The low value clothes were perceived to be higher in both initiative and dignity.

This paper describes the Blue Ocean Strategy and Business TRIZ (Russian Theory of Inventive Problem Solving) Tactics as one method for knowledge creation and innovation. The opening new market avoiding keen competition is very popular recently and is not just prosper, but survival problem. As one new strategy for finding new market, the Blue Ocean Strategy gives the big blueprint for new market, but has no enough tools to make more concrete ideas. In this paper, we suggest using the Strategy Campus and other tools in the Blue Ocean Strategy at initial stage and then, compensating the TRIZ principles to make more concrete ideas for new market as tactics. We applied it to find the new market for conventional newspaper industry and EBS (Education Broadcast System) management innovation in Korea as case studies and got better results comparing to using only the Blue Ocean Strategy.

A high efficiency deep blue phosphorescent organic light-emitting diode (PHOLED) was developed using a new wide triplet bandgap host material (PPO1) with a phenylcarbazole and a phosphine oxide unit. The wide triplet bandgap host material was synthesized by a phosphornation reaction of 2-bromo-Nphenylcarbazole with chlorodiphenylphosphine. A deep blue emitting phosphorescent dopant, tris((3,5-difluoro-4-cyanophenyl)pyridine)iridium (FCNIr), was doped into the PPO1 host and a high quantum efficiency of 17.1 % and a current efficiency of 19.5 cd/A with a color coordinate of (0.14,0.15) were achieved in the blue PHOLED. The quantum efficiency of the deep blue PHOLED was better than any other quantum efficiency value reported up to now.

(Most companies that perform BPR have not achieved satisfactory results or have not performed successful BPRs. There are many reasons for this, but the most important one has caused problems that do not accurately reflect the requirements of various stakeholders. In this paper, we will apply the BPR consulting methodology to a new value innovation requirements engineering process based on the Blue Ocean strategy, which is a way to create a new market without competition by customerizing potential customers by satisfying new customer expectations and needs. This paper uses a requirements engineering process that can generate customer value by applying the ERRC(Erasure Reduce Raise Create) analysis method, which is the core of the Blue Ocean Strategy Framework[1,2]. We will also apply the Six Sigma DFSS (Design For Six Sigma) methodology to improve quality and process through quantitative and systematic analysis. The proposed approach was presented to the BPR consulting to present a practical case, and the results of the empirical analysis of the system user to validate the results of BPR consulting.

This study's goal is to analyze the color characteristics of Blue used in men's fashion for design developing process. First, we researched the previous studies and examined documents about color characteristics of Blue in general as well as coloration in fashion design and men's fashion. We composed color samples by collecting two-color coloration used in men's fashion collection for 5 years from 2004 S/S to 2008 F/W through a specialized fashion information web-sites. We limited the colors from Blue Green(BG) to Purple Blue(PB). Second, we analyzed the characteristics of hue combination and tone combination. A total of 351 pictures were collected and RGB and HV/C value were converted with Munsell Conversion program(ver.8.0.1). Color data has been sorted to 10 hues and 12 PCCS tones. From this, we were able to figure out that similar/same hue coloration was used more than contrary hue coloration and similar/same tone coloration was used more than contrary tone coloration for Blue. We've limited Blue coloration characteristics of men's fashion to two-color coloration for an analysis; the succeeding study will need to examine on the characteristics of multi-coloration and detailed Blue coloration image by various garments.

This study determined the characteristics of LED illumination and photosynthetically active radiation flux density (PPFD) for LED lighting design in an indoor plant factory. This was done based on the light wavelength and PPFD intensity required for plant growth. It has been found that the wavelength and intensity are decreased according to the measuring distance, and green light has an important role in illumination characteristics, while blue light has an important role in the PPFD characteristics. Considering only the photosynthetic properties of plants, the effective order of photosynthesis was blue>red>white>green. When the measurement distance was 30 [cm], it was found that reduction levels of 60 [cm], 90 [cm], and 120 [cm] decreased to about 36 [%], 18 [%], and 10 [%], respectively. As a result of the characteristics of mixed light (red:blue=2:1, 3:1, 4:1) and the measurement distance, when the measured value at 30 [cm] is 100%, the measured value at 120 [cm] is 10-11 [%]. From the obtained results, an optimal structure was proposed for maximizing the light efficiency of an indoor greenhouse for future research.

This study was carried out to investigate the suitability of colored barley in malting and brewing properties and the possibility of utilizing pigments in colored barley as functional components in malting and brewing products. Purple and blue barley grains contained anthocyanins. However, about 80% and 20% of anthocyanins in the purple and blue barley grains, respectively, were lost during the steeping process. In malts, only 0.4~4.2% and 58.3% of anthocyanin in purple and blue barley grains, respectively, were remained. Wort color value was not affected by lemma color of black barley. In wort made from black barley, the color value was higher as its soluble nitrogen content higher. Anthocyanins were not found in wort and beer brewed from malts of purple and blue barley. The color value (EBC unit) was higher in wort and beer made from malts of purple and blue barley than those made from malt of the control variety, Hopum.

Traditional patterns of Korea vary greatly and have excellent value in terms of artistic merit. Nevertheless because there are not enough the research and development of them, traditional patterns of Korea are not yet recognized in internationally aesthetic value. Therefore the development of designs modernizing traditional patterns of Korea is urgently needed. In this study, I chose Four gracious plants as the subject materials of textile design development. Before everything I examined data of Four gracious plants expressed on Blue and white porcelain. And I chose data that are suitable to express modern image among them. I set my face to develop the textile design of Korean images by adding modern scenes with them. Also, I were trying to make fashion products like muffler and tie by using techniques such as burn out, crayon dying and spray dyeing.
