The beauty industry of today tends to gradually develope as one of the important marketing strategies along with the total fashion sector. Hair color, being one of the factors of hair style, especially builds his or her own image and even becomes the nonverbal communication method which let others know him/herself. Therefore, women's needs and expectations of hair coloring are varied. To meet these need, it is urgent to figure out, most of all, the status of customers' awareness about hair coloring. Thus, in this study, research and analysis on hair coloring were made, focusing on the women utilizing 20 beauty shops in Changwon city. And the goal that this study set is to use as the study material for the hair coloring consulting in the beauty industry and the basic data for marketing in the industry job-sites. The conclusion by the three factors(age, job, monthly income) were as follows: 1. Dandyism was on the 1st order in the reason for coloring hair regardless of age, job, and monthly income. This seems to be speaking for the change of women's awareness of coloring hair. 2. The subject of making decision upon whether she was going to color her hair or not was herself regardless of age, job, and monthly income. Among the people belong to these three factors, brown was the color in overall preference. 3. More than half of those who belong to the three factors were not aware of the hair color, but their senses and interest in the color in vogue were high. 4. In terms of the hair coloring periodic time, many people had $2{\sim}3$months, but it was possible to know that they were interested in improving their images, considering the fact that most of the salaried people had their hair dyed within a month and the people in service job over a month. 5. The acquaintance around me had the strongest effect in collecting information from the people in those three factors and mass media was the next. The results of this study, in my opinion, would help the customers have beautiful and healthy hair and make images of their own by making the hair designers develope professional knowledges and skills on the hair coloring and improve the quality of beauty services.

PURPOSE. The aims of the study were to evaluate the fracture load of zirconia core material after dipping in coloring liquid at different time intervals and to compare the color of dipped blocks with that of prefabricated shaded blocks. MATERIALS AND METHODS. 3-unit bridge frameworks were designed digitally. Sixty frameworks were fabricated using uncolored zirconia blocks by CAD/CAM and divided into 4 groups randomly (n = 15). Group 2 (G2) was subjected to coloring liquids for 2 minutes, Group 4 (G4) for 4 minutes, and Group 6 (G6) for 6 minutes. CFS group was not subjected to any coloring procedure. After coloring, color differences between the test groups and a prefabricated shaded zirconia group (CPZ, n = 15) were evaluated by using a spectrophotometer. Fracture test was conducted immediately after shade evaluation with a Testometric test device at a cross-head speed of 1 mm/sec. Statistical analysis for evaluating color and fracture load was performed by using one way ANOVA followed by Tukey HSD test ($P{\leq}.05$). Weibull analysis was conducted for distribution of fracture load. RESULTS. There was no difference in terms of fracture load and color between CFS (1176.681 N) and G2 (985.638 N) group and between CPZ (81.340) and G2 (81.140) group, respectively. Fracture load values of G4 (779.340 N) and G6 (935.491 N) groups were statistically significantly lower than that of CFS group ($P{\leq}.005$). The color values of G4 (79.340) and G6 (79.673) groups were statistically different than that of CPZ group ($P{\leq}.005$). CONCLUSION. Prolonged immersion of zirconia in coloring liquid not only negatively affected the fracture load of the zirconia being tested in the current study but also deteriorated the desired shade of the restoration.

This study examines the Korean traditional and characteristic coloring through the color of Korean traditional embroidery. This research gives the chance to establish the cultural identity of Korea and presents the aesthetic standard of color images. Also, practical use of Korean traditional colors through this study provide opportunities which develope cultural merchandise in the world. were chosen as the references to analyzed the Korean traditional colors through gungsu: court embroidery, buddhist embroidery, everyday embroidery and clothing embroidery. Because this book published in commemoration of '20th General Conference and 21th General Assembly of ICOM' in 2004, which presented excellence of Asian culture. The color of these works were divided by 'Pantone Solid Color Chips' which organized by CMYK color system and categorized by Obangsaek. 'Gungsu' had vivid and splendid color sense which used strong and bright colors and 'buddhist embroidery' had mild and mysterious feelings which used low saturation.'Everyday embroidery' used the red color group frequently and 'clothing embroidery' had brighter colors comparing to other embroidery groups. The 'Chung(blue)' group had diverse color tone rather than one-tone color. This means that Koreans prefer the 'Chung' and used it regularly, also this color symbolized the racial characteristics. Even though 'Whang(yellow)' was prohibited because the color for emperor, in the case of embroidery, there were a variety of yellow colors from 'gold' to pale yellow and grayish yellow. The arrangement of colors in 'gungsu', tone on tone, complementary and bicolore coloring was used mostly which presented a strong and elegant color sense. On the other side, 'buddhist embroidery' used tonal coloring which gave gentle and noble feeling. 'Everyday embroidery' presented separation and accented coloring which was the example of common people's humor and originality. In the case of 'clothing embroidery', there was dominant lightness, separation, tone on tone and camaieu coloring which added gorgeousness in Korean traditional clothing.

Soluble methyl-hesperidin (MH) powder was prepared from crude MH, and was investigated on the stabilization to sunlight of natural coloring matter. Soluble MH powder was added to riboflavin, bixin, and paprika oleoresin solutions at concentration of 0.1 or 0.2%(w/w), and the absorbance of respective solutions was analyzed by spectrophotometer after exposing to sunlight for $10{\sim}24$ hr. While coloring matter solutions without MH was faded completely with lapse of time, addition of MH retarded to fade natural coloring matters. According as amount of MH added increased, MH showed more excellent stabilizing effect on the coloring matters. Especially, vitamin C with soluble MH showed remarkable synergistic effect in paprika oleoresin solution during the exposure to sunlight for 8 hr. Consequently, it was found that MH plays a role as excellent stabilizer of natural coloring matters to ultraviolet of sunlight.

People with color vision deficiency (CVD) experience difficulties in discriminating some color combinations and color differences due to the abnormal retinal cone systems. While there exist smartphones with a re-coloring function for CVD, monitors do not provide the re-coloring function. In this paper, we propose a new re-coloring algorithm that adjusts the displayed colors for CVD using a color controller embedded in the monitor. The proposed algorithm converts the hue and saturation in HSV color space, according to the type and strength of the color deficiency. The results of the performance evaluation with a certain number of people with CVD show that the proposed system can convert colors imperceptible into perceptible.

Hair coloring before the 1980s was mostly to hide white hair by dying in black. With the introduction of color TV, however, the size of the coloring market has been expanding. Nowadays, artificial synthetic dyes are widely used, which, though advantageous in many points, have problems such as harmful effects on the human body, carcinogenesis, environmental contamination and damage on hair. On the contrary, natural vegetables obtained from Curcuma Longa L., A. catechu, polygonum indigo, henna, etc. are little harmful to hair or the skin of the head and cause few environmental problems. In addition, as they are natural materials collected from nature, they are considered positively by consumers. Thus the present study started from the necessity of research on the convenient use of environment?friendly and side-effect-free natural dyes, coloring technology for reproducing original color, the improvement of adhesion rate, etc. From the present research were obtained yellow color from Curcuma Longa L., brown from A. catechu, blue from polygonum indigo and orange from henna. It is expected that, based on materials from previous researches, there may be more researches on the use of natural dyes as hair colors.

The tactical communications network has to be deployed rapidly at military operation area and support the communications between the military command systems and the weapon systems. For that, the frequency assignment is required for backbone wireless links of tactical communications network without frequency interferences. In this paper, we propose a frequency assignment method using net filter discrimination (NFD) and graph coloring to avoid frequency interferences. The proposed method presents frequency assignment problem of tactical communications network as vertex graph coloring problem of a weighted graph. And it makes frequency assignment sequences and assigns center frequencies to communication links according to the priority of communication links and graph coloring. The evaluation shows that this method can assign center frequencies to backbone communication links without frequency interferences. It also shows that the method can improve the frequency utilization in comparison with HTZ-warfare that is currently used by Korean Army.
