Information delivery among young generation has a distinct tendency to prefer visual to text as means of information distribution and sharing recently, and it is natural to distribute information through Youtube or one-man broadcasting on Internet. That is, young generation usually get their information through this kind of distribution procedure. Many young generation are also drastic and more aggressive for decorating themselves very uniquely. It tends to create personal characteristics freely through drastic expression and attempt of face makeup, hair styling and fashion coordination without distinction of sex. Especially, face makeup becomes an object of major concern among males nowadays, and female of course, then it is the major means to express their personality. In this study, to meet the demands of the times, we design and implement the intellectual smart mirror application that efficiently retrieves and recommends the related videos among Youtube or one-man broadcastings produced by famous professional makeup artists to implement the face makeup congruous with our face shape, hair color & style, skin tone, fashion color & style in order to create the face makeup that represent our characteristics. We also introduce the AI technique to provide optimal solution based on the learning of user's search patterns and facial features, and finally provide the detailed makeup face images to give the chance to get the makeup skill stage by stage.

This study investigated differences in perception by 240 males in their teens, 20s, 30s, and 40s residing in Seoul, Incheon, and Gwangju about seven items for male makeup, and analyzed makeup items preferred by men, perception about male makeup users, and relationship between success and appearance, thereby providing basic materials to activate the beauty market for males and developing goods for male users. The result was that most males thought the influence of their appearance on their social success was great and in particular, 23.3% of respondents thought that their appearance affected their success by 50% or higher percentage. The items most preferred by the respondents were concealers, color lotions, and BB creams; 60.8% considered them positive. This showed that basic color cosmetics had already been established as one of the essential goods for men. In contrast, the respondents had slightly negative perception about items like mascaras, eyeliners, and eyeshadows. Overall, those who were young, unmarried, and city dwellers had positive perception about such cosmetics by and large. The above data will be able to be used to develop various makeup goods for male consumers oriented toward success and implement diverse marketing strategies, thereby activating the beauty market for males.

This study is to examine personal color - preferred color, well-matched color and the relations between preferred color and the well-matched color. Focus is also placed on how sexual difference influences color temperature preference. For data collection, a questionnaire including color stimulus was employed. The subjects of this study were the male and female college students who lived in Pusan. The results of the research are summarized as the following : In view of preferred color, male subjects preferred KEY2 color(warm) in red, pink, and yellow, and preferred KEY1(cool) in green and blue. While most subjects showed the same signal, in green, male preferred KEY1 color and female preferred KEY2 color. Concerning preferred personal color type, KEY1 type person liked KEY1 color except red, and KEY2 type person liked KEY2 color except blue. This shows that people prefer the focused color presenting its own traits. In view of well-matched color, most subjects liked KEY2 color in red, yellow, pink, and they selected KEY1 color in blue as the well-matched color. However, in green, each sex showed different preferences; while male subjects selected KEY1 color as the well-matched color, female ones selected KEY2 color. In each personal color type, KEY1 type male evaluated KEY1 color as the well-matched color, KEY2 type male evaluated KEY2 color except blue. KEY1 type female chose all the KEY1 color as well-matched colors, and KEY2 type female chose KEY2 color. The well-matched colors are similar between male and female subjects. In over 80 percentage of the answers, the preferred colors coincided with well-matched colors. KEY1 type persons chose KEY1 color, and KEY2 type person chose KEY2 color as the well-matched color. These results show that there is a meaningful relationship between the preferred color and well-matched color.

Digital cable TV(DCATV) is totally different with a existing TV which is passive, and can pick the contents anytime we want. It is very popular in many houses and we can see bright future with this. This study will show a standard that is a suitable and convenient VOD menu category for 20's through a various usability test. Moreover it will be provided new menu style and GUI through the preferences. For this, we found expected problems first through the heuristic analysis and did iterative usability test to verify and improve these problems. As a result of that, we improved errors of VOD menu structure and suggested new menu style including metaphor, colour and icon users can recognize easily. That is, VOD categories should be grouped among definite meanings. And we found using convenience is more important than new discovery of method on menu style for experienced users. This study can be not only based data when DCATV menu is renewed but also can be used as a reference data when designing other DCATV menu.

The purpose of this study was to investigate the male perceiver's image evaluation on women's hairstyle and hair color, and to disclose the preference of the hairstyle and hair color. The experimental design was $2{\times}3{\times}3$ (hair $wave{\times}hair\;length{\times}hair$ color) factorial design by 3 independent variables. The stimuli were 18 women's upper body photographs which were output by computer simulation. The hairstyles were straight hair and wavy hair, and the types of the hair length were long, medium, and short hair. The hair colors were black, dark brown, and bright brown. Subjects were 154 men living in Seoul. The data were analyzed by using factor analysis, Cronbach's ${\alpha}$ reliability coefficient, three-way ANOVA, one-way ANOVA, and Duncan's multiple range test. The results of this study were as follows. Four image dimensions were derived by factor analysis. These were individuality, elegance, potency, and attractiveness. Male perceivers evaluated the women's long hairstyles to be more elegant than the short and the medium length hairs. The women's short hairstyles were perceived more potent than the long and the medium length hairs. The straight hairs were evaluated more elegant than the permed hairs, and the permed hairs were evaluated higher in individuality and attractiveness. The black hairs were perceived lowest in attractiveness, and the bright colors were perceived low in elegance. Male preferred the long brown straight hair first. They liked women's long hairs better than the short and the medium length hairs. Teenaged males preferred various hair colors more than those in their 20's and 30's did.

It is important for the strategy of cosmetic sales to investigate the sensibility and the preference degree in the environment that the makeup style has been changed focusing on the consumer center. We proposed the human sensibility ergonomics makeup recommendation system (MakeupRS) using the context sensor information applying the collaborative filtering technique as one of methods in the makeup style development centered on the consumer's sensibility and the preference. In the collaborative filtering technique, the Pearson correlation coefficient applying to the case amplification is used to calculate similarity weights between the users. To investigate the sensibility according to the effect of makeup styles, the makeup styles were analyzed in terms of 6 style factors, such as, the foundation, the color lens, the eye shadow, the eye lash, the cheek brusher, and the lipstick. Ultimately, this paper suggests empirical application to verify the adequacy and the validity with the human sensibility ergonomics makeup recommendation system.

Analysis of design preference to Korean and Chinese casual style were made targeting Chinese female students in Korea. The following conclusion was derived from the result of final 300-copy survey data, using SPSS 18.0 program. The data were analyzed by frequency, t-test, chi-squre independence test, ANOVA and Scheffe test. Firstly, when comparing change of design preference before the stay in Korea with after the stay in Korea, the biggest change in their preference was character casual style, while the least change was easy casual wear. In terms of duration of stay in Korea, the biggest change was from the group of over 3 years, and in the order of the group of 1-3years, and then lastly less than 1 year, which suggests that the longer the duration of stay, the bigger the change. When comparing preferred clothing color before the stay in Korea with after the stay in Korea, both before and after the stay in Korea had the highest preference for achromatic colors. The frequency of change was mostly from achromatic color to other colors. In the preferred clothing pattern, 'plain' was their favorite one before the stay in Korea, while it turned to 'nature pattern' after the stay in Korea, followed by 'plain' one. In the textiles, the most preferred one was 'cotton', before and after the stay in Korea. However, their preference for cotton was lower after their stay in Korea than before the stay in Korea, and instead there was more preference for 'silk', 'synthetic fiber', and 'other' sources.

In this article, we suggest a new method for measuring an aerosol's extinction coefficient using a commercial camera. For a given image, we choose three pixel-points that are imaged for the same kinds of objects located in similar directions. We suggest and calculate aerosol extinction coefficients from these RGB gray levels and the different distances of the three objects. To compare our measurement results, we also measure extinction coefficients using lidar. Finally, we find that there are meaningful and sensible correlations between these two measurements, with a correlation coefficient of 0.86. We measure the aerosol extinction coefficient at three different RGB wavelengths using the same method. From these aerosol extinction coefficients at three different wavelengths, we find that the Angstrom exponent ranges from 0.7 to 1.6 over a full daytime period. We believe that these Angstrom exponents can give important information about the size of the fine particles.

Though human being has ability to percept a full colored vision, the technology of early photography only can produce black and white images. For cinema filming imagery also captured mono tone with black and white, until developed a color film technology. The desire for presenting color imagery and the technique for producing film and color ink, photography and print utilize color on it with noticeable color impact to viewers. It, however, abusing fun colors image each and every printed and filmed imagery, the freshness of eye catching power diminished now. On contrast, color becomes black and white or partially used for making discrepancy among full colored images. This image detected commercial and music video, and it spread to film. To use those bleached color images is for evoking a nostalgia and a visual differentiation. Especially, it can be provocative images brought to audience with that. such as "Anycall", "Dimchae" for CF, and "Schindler's list," and "Sin city" for movie. It is hard to investigate on the color studies for partially used images. Therefore, this study is to research that through CF and film, base on it, to investigate the application for this image. To collect data from survey, it will be established a basic concept for understanding the partial color applying.
