The purpose of this study was to observe the makeup behavior and cosmetics preference based on the segmented age group and fashion appearance interested group. The target consumers were women aged in their 20's. We distributed 443 questionnaires and conducted statistical analysis using SPSS program for the 400 reliable questionnaires. Statistical analyses included frequency, Chi-square test, t-test, ANOVA and cluster analysis(K-means). The results of this study were as follows: 1. There was a significant association between specific cosmetic items currently used and segmented age group. The age 24-29 had more basic makeup than color makeup, compared to the age 20-23 group. There was a statistical difference between the highly interested group and the lowly interested group in fashion and beauty. The group of highly interested in fashion and beauty considered trendy colors, while the group of lowly interested in fashion and beauty used their favorite color as an important factor in purchasing makeup products. 2. There was a significant difference in the preference of lip colors and textures, eye shadows textures, types of eye liner and types of foundation according to segmented age groups. 3. Those who sought 'sexy' images preferred red/wine/purple lipstick colors, and green/blue/violet eye shadow colors. They significantly preferred jell/liquid type eye liner and liquid type foundation. Those who sought 'pure' images preferred orange colors and glossy textures of lipsticks. Those who sought 'elegant' and 'intellectual' images preferred pearl type eye shadow.

This study is on the abstract expressionist techniques among the art activities variously expressed in modern fashion. Its significance lies in making fashion artistic through the combination of fashion and art in contributing to the development of creative fashion culture. In terms of method, documents are used to characterize the concept of abstract expressionism, the works of representative artists, and the panting techniques in relation to modem art based on existing literature. Fashion-related anthology, domestic, and foreign fashion magazines were used to analyze the abstract expressionism applied to modern fashion since 2000. According to the findings, the abstract expressionism applied to modern fashion showed artistic expressions with the abstract beauty by chance, using only the images or techniques similar to those in abstract expressionism. Expressionist works had abstract and dynamic images, as they were given a third dimension through the process of being worn on the human body. Second, details or decorative factors were excluded to ensure the maximum space for expression, modem images were displayed using the simple forms such as silhouettes (spacious or dense) and the beauty of harmony was shown that had beauty emphasized by the expression effects of textile design, the division of space, and the composition of colors. Third, the action painting techniques in modern fashion were used for textile designs printed on the surface of clothes, and the dynamic character of the design was shown by the duplication and juxtaposition of stains created by chance. The color field abstract techniques were shown through printing, texture, and dying, in addition the intense and pure abstract images were displayed by treating clothes like large screens.

In this study, an Co/Fe coated porcelain using a cobalt and ferrous sulfate was sintered at 1,250 ℃. The specimens were investigated by HR-XRD, FE-SEM (EDS), Dilatometer, and UV-vis spectrophotometer. The surface of the porcelain was uniformly fused with the pigment, and white ware and celadon body specimens were densely fused to a certain thickness from the surface. Other new compounds were produced by the chemical reaction of cobalt/ferrous sulfate with the porcelain body during the sintering process. These compounds were identified as cobalt ferrite spinel phases for white ware and white mixed ware, and an andradite phase for the celadon body, and the amorphous phase, respectively. As for the color of the specimens coated with cobalt and ferrous mixed pigments, it was found that the L^* value was greatly affected by the white ware, and the a^* and b^* values were significantly changed in the celadon body. The L^* values of the specimens fired with pure white ware, celadon body, and white mix ware were 72.1, 60.92, 82.34, respectively. The C7F3 pigment coated porcelain fired at 1,250 ℃ had L^* values of 39.91, 50.17, and 40.53 for the white ware, celadon body, and white mixed ware, respectively; with a^* values of -1.07, -2.04, and -0.19, and at b^* values of 0.46 and 6.01, it was found to be 4.03. As a new cobalt ferrite spinel phase was formed, it seemed to have had a great influence on the color change of the ceramic surface.

Recently more than ever, interest in Korean tradition has been on the increase, with an active movement to follow tradition. There are various merits for expression with the use of Korean paper as a clothing material. The purpose of this study was to assess the aesthetic characteristics of men's shirts fashioned using Korean paper (Hanji). The following conclusions were obtained from an analysis of the aesthetic characteristics of Hanji shirts. First, Hanji has a peculiar texture, with natural characteristics due to the direct use of naturally handcrafted materials. Hanji shirts have the natural beauty of pure Hanji, without artificial treatment or other subsidiary materials, with the exception of thread. Secondly, Hanji shirts with decorative details and trimmings, such as frills, pin tuck, embroidery and spangles, express an ornamental beauty. Thirdly, Hanji shirts with frills or a fringe have real movement when worn and spangles give the illusion of movement due to changes in color or twinkling caused by light giving the beauty of rhythmical motion. Fourthly, Hanji shirts produced using the application of various techniques, such as crumple, painting and dying, express artistic beauty. Fifthly, Hanji shirts can express traditional beauty, even if created whit modem designs, but using traditional materials.

The purpose of the study is to produce a mechanically improved weld and minimum variation of color through comparing unpulsed and pulsed GTAW (Gas Tungsten Arc Welding) for pure titanium (CP grade7) tube. Pulsed GTAW using 60 A peak current and 20 A background current (1:9) achieved the wider window of welding conditions having part and full penetration without burn-through than the case of unpulsed GTAW. Moreover, the pulsed welding reduced a discoloration on the back bead of the weld and the size of microstructures (basket weave and serrated ${\alpha}$). That is because the pulsed welding has it's a low heat input and severe weld flow induced from electric current variation. Furthermore, the pulsed welding improved the bending property of the welded Ti tube. The enhanced bending property for the pulsed GTAW was due to the insignificant discoloration on the weld surface with maintaining the metal polish.

We report a new series of blue dopants composed of both electron donating and electron accepting moieties in one molecule, based on nalidixic acid. The EL device derived from the dopant exhibits pure blue light emission (0.15, 0.14) The current efficiency is estimated to be 3.88 cd/A at 100 $cd/m^2$, which shows remarkable enhancement, compared to that of the host itself (2.5 cd/A at 100 $cd/m^2$) under the same conditions. These results demonstrate that the incorporation of a proper guest into the host in a guest-host doped system improves not only the purity of the fluorescent blue emission but also elevates its quantum efficiency, thus improving the OLED performance.

As a mirror of its time, fashion exactly reflects the trend of today' s society. In addition, as a tool to satisfy our desire and express images, it brings diverse image changes in people's minds. This kind of pattern is frequently found in wedding images, especially in wedding dresses. When it comes to a wedding dress, in general, we often think of a modest and pure-white one. In modem times, however, people prefer a differentiated image which reflects their personality and ego. In other words, it is an important means of expressing their own personality by focusing on their active and personal aspects and getting away from the passive, stable and formative aspects in the past. These days, a combination of narcissism and eroticism is found on wedding dresses. This kind of trend has been expressed into romanticism. In terms of the latest sensitive wedding dress trend, unique and creative couture wedding dresses have appeared. Therefore, this study has classified this kind of trend into two categories; Formative and Design aspects. According to an analysis on the formative and design aspects of romanticism in wedding dresses, diverse characteristics were observed in shape, color, material and ornament in the Formative Aspect. In terms of design, the characteristics of sensuality, ornament, exoticism and compromise were observed.

For estimation of three inherent optical properties (IOPs), the absorption coefficients for phytoplankton ($a_{ph}$) and suspended solid particle ($a_{ss}$) and dissolved organic matter ($a_{dom}$), from ocean reflectance, we used inversion of remote sensing reflectance model (Ahn et al., 2001) at this study. The IOP inversion model assumes that (1) the relationship between remote sensing reflectance ($R_{rs}$) and absorption (a) and backscattering ($b_{b}$) is well known, (2) the optical coefficients for pure water ($a_{w}$, $b_{bw}$) are known, (3) the spectral shapes of the specific absorption coefficients for phytoplankton ($a^*_{ph}$) and suspended solid particle ($a^*_{ss}$) and the specific backscattering coefficients for phytoplankton ($b_b^*_{ph}$) and suspended solid particle ($b_b^*_{ss}$) are known. The input data of IOP inversion model is used in-situ ocean optical data at the seawater around the Korea Peninsula for 5 years (2001-2005). We compared the output data of the IOP inversion model and the in-situ observation for seawater around the Korea Peninsula.
