This study investigated EEG signal, subjective fragrance sensation, and the preference of differently colored cotton knit treated with Citrus unshiu oil containing microcapsules as well as examined their relationships for providing regression models on subjective fragrance preference. Color variables combining 2-level hue (Yellow and Green) and 3-level tone (strong, pale, and grayish) were applied by dyeing prior to microcapsule treatment. We invited 28 female college students aged 20's for EEG signal experiments and subjective fragrance sensations with fragrant knit by rubbing. EEG signals at $mid-{\alpha}$, $fast-{\alpha}$, and $low-{\beta}$ showed significant differences depending on color; Green had more relative power values and grayish tone did more at $low-{\beta}$. Even though subjective sensation showed no significant differences depending on color, some of them such as Fresh, Comfort, and Natural showed significant correlations with EEG signal at $low-{\beta}$, which means that the fragrance sensations of Citrus unshiu fragrance are concerned with attention and alertness for Koreans. Fragrance preference was regressed significantly using some EEG signals and subjective sensation. The results could be utilized to value up fragrant textiles by Citrus unshiu oil.

To quantitatively analyze the effects of color stimulation which is one of the major affecting factors on human emotion, we studied the relationship between color preference and the Electroencephalography (EEG) to 3 color stimuli; bright yellow red (BYR), deep green yellow (DGY), and vivid blue (VB). Physiological signal measured by EEG on the color stimulation was closely related with their well-known colorful images. The brain become more activated with decreasing the color temperature (BYR${\geq}$DGY>VB), and the right brain is more sensitive than the left. On the whole, the EEG values of the frequency bands are in order to beta ${\geq}$ theta and alpha > gamma. As decreasing the color temperature, beta wave increased (BYR${\geq}$DGY>VB), and alpha, beta and gamma waves increased with increasing the color temperature (BYR${\geq}$DGY>VB). The relationship between the color preference and EEG values showed EEG gets more activated at some frequency bands when the color preference becomes higher. In conclusion, the specific frequency band could be activating by a color stimuli which had showed higher the preference. It means that these color stimuli can apply for various industries such as beauty industry, interior design, fashion design, color therapy, and etc.

The elements to enhance preference in symbol design are mainly related to consumers' response and aesthetic elements. Because certain aesthetic elements in design affect consumers' response and it is actually presented through (the different level of) preference. This study through surveying case studies examines whether a certain aesthetic element in symbol design gives rise to much preference. According to the result of study, high preference in symbolic design depends on high level of Rhythm, Balance, Harmony, Elaboration, Round, Gestalt, Organic, and Artificial/Natural among aesthetic elements. In comparison, it is founded that Simplicity/complexity, Objective/Abstract, depth, and symmetry should be designed at the moderate level, and proportion, repetition of elements be at the low level. Additionally(or Besides) this study makes out that symbol design cases with high preference have shapes from natural material or patterns of traditional culture, while cases with low preference have shapes from geometric figures. On the basis of these results, a guideline of symbol design could De offered(or suggested) to fit preference of consumers. But, this study is mostly concerned with only affect among emotional reactions of consumer in a scope of study, and is considered only in the aspect of form excluding color and texture.

The main causes of traffic accidents while driving a car is of the driver's visual distraction. In this study, the color sensitivity of the information projected on the windshield were evaluated for HUD (Head Up Display) system which helps the driver's eyes on the road while driving. The driving Information were projected $9^{\circ}$ downward from front sight $0^{\circ}$ under lab's fluorescent lights, LED floorlights and the TV had having 25 [lux] illumination when driving at night environment and 100,000 [lux] of daylight environment. Munsell color hue of the basic five colors (R, Y, G, B, P) and the color of traffic lights YR, W were the color of the seven characters, each character were outlined by White, Gray except for W. Total of 19 experimental stimuli was shown in the environment of day and night driving for asking visibility information of color, fatigue, preferences, and evaluate the degree of interference. The results came out that the bright Y and G color is visibility significantly for daylight. Second, with the outline of the text, the color of the outline works as a background for luminance contrast effects and affects visibility. Third, without the outline, the glass in front of the vehicle acts as the background and the luminance contrast of characters achieve greater brightness and visibility. The luminance contrast between the stimuli and background should be considered for increasing color visibility for driving information which is an important factor for HUD commercialization.

제품 구입시 구매욕구를 일으키는 요소는 제품 속에 내재되어 있는 형태와 색이다. 제품개발자는 제품디자인의 시발점으로 기초도형에 대한 연구가 필요하고 이러한 기초도형의 감성은 결국 구체적인 디자인 형태로 변환될 경우 상당한 기초자료로 제시할 수 있을 것이다. 또 체계화된 기초자료를 이용하여 소비자의 취향에 맞는 제품의 개발을 촉진시키고, 소비자 계층의 유형별 분류와 상품군의 세분화 작업을 가속화시켜 상품의 양적 생산에서 질적생산으로 전환시킬 수 있는 계기가 될 것이다. 본 연구에서는 이러한 목적을 가지고 제품요소의 기본이 되는 형태와 색상에 있어서 시각감성이 지역, 성별, 도형간에 어떠한 차이가 있는지를 살펴보고자 한다.

The skin-tone in portrait photography is one of the most sensitive parts that need retouching by a photographer. To investigate the emotional reactions related to users' preferences for the skin-tone variations in portrait photography, two experiments were conducted. The first experiment included JND(Just Noticeable Difference) test to determine the general distribution of preferences with many photographs that varied in phases up to an extreme one, as a result, preferences for the brightest skin-tone and the red or magenta one were found. Based on the first experiment, we reduced the number of samples by adjusting their brightness to the brightest phase constantly. To intensify the second experiment, we reduced the number of the other colored samples to only one and made samples for five phases from green to magenta, namely the most preferred skin-tone in the first experiment. In the second experiment, the common preference for a neutral skin-tone and the partial difference between the two gender groups were found. In conclusion, the users' preference for a particular skin-tone was positively affected by emotions such as 'happiness' or 'comfortable'. With this investigation, we compiled some statistically meaningful facts to confirm that the preferences of the users depend positively on controlling the skin-tone in portrait photography.

Everyone has own color preference and the color preference can affect human psychology in various good or bad ways. Especially patients with chronic diseases often have depressed mood to take pills for their disease treatment. Therefore we evaluate the possibility of their color preference to pharmacotherapy in good way which increases the compliance of pharmacotherapy. We performed this study by a Questionnaire survey for total 150 agreed patients at K University hospital from Aug 7 to Sep 30, 2014. Questionnaire survey was performed to choose color of providing color kit (11 different color range kit) depend on each 16 questions which asked the patient characteristics, health condition, general color preference, color preference for medicine and expectation for drug compliance. In results, most preferred color was blue (20%), whereas disliked color was black (30%) in general life. However, most preferred color for pill was white (32%), for syrup was also white (31%) or orange (28%), and for vitamin was yellow (47%). When we asked the possibility of increasing compliance, if the current taking pill color will be changed for your preference color like a candy bar, 50.4% of respondents marked 4 or 5 of like-scale expressing positive opinion on it. In conclusion, compliance is very important to succeed the treating disease and may apply the psychologic application such as each patient color preference for drug compliance in the future.
