The purpose of this study is to examine the makeup color range for developing the new makeup product line of domestic cosmetic brand, and suggest the special color stories and color palettes appropriate to characteristics of brand image For this study, personal color images are analyzed and classified through the literature survey of Korean womens' skin rotor like korean PCDS and japanese PCS. Also, a total of 3879 colors were selected from the 18 cosmetic brands and were analyzed by hue/tone color system. Based on the color analysis, the color range for makeup products are determined, and the typical colors of 4 personal color images are suggested. As a results, personal color images are classified into 4 types: DEW of p, lt, b tone; FLASH of s, v tone; MIST of ltg, g, sf, d tone; TERRA of dk, dkg, dp tone. we developed the color stories through five senses and lifestyles based on the consumers' emotion, and the rotor palettes suitable to each type of personal color images are developed.

This study was intended to make Korean type of sourdough bread using domestic wheat produced in Korea, while measuring and analyzing gluten content, pH level, TTA level and mixograph of wheat to extract the most excellent sourdough starter. Furthermore, this study also used CrumbScan to compare and analyze the properties of product as shown in making sourdough bread with the above starter. pH level ranged from 4.0 to 4.5 throughout all kinds of Korean wheat flour, which were considered to be appropriately available as sourdough starter. As the result of analysis from mixogram, SP fit for making bread but korean wheat flour showed less level of mixing tolerance and content of protein, which were considered inappropriate for making bread. As the result of imaging analysis by CrumbScan, SF, KWF 5and KWF 6 showed the higher fineness and elongation than any other kind of korean wheat flour, which were considered appropriate for making bread.

The objectives of this study were to evaluate the effect of surface roughness on the surface color and translucency of the composite resins. Two composite resins (Esthet-X, Dentsply, Milford, USA and Charisma, Kulzer, Domagen, Germany) were used to investigate the surface color. Charisma was used to investigate the translucency. 40 disc samples (diameter: 8 mm, thickness: 5 mm) were made by each product to measure the surface color. Polymerized each sample's one side was treated by Sof-Lex finishing and polishing system (Group C, M, F, SF). 40 disc samples (diameter: 6 mm, thickness: 1 mm) were prepared to measure the opacity. 1 mm samples were ground one side with #600, #1000, #1500 and #2000 sandpapers. CIE $L^{*}a^{*}b^{*}$ values of each 5 mm thickness samples, and XYZ values of 1 mm thickness samples on the white and black background were measured with spectrophotometer (Spectrolino, GretagMacbeth, Regensdorf, Switzerland). Mean surface roughness (Ra) of all samples before and after surface treatment was measured using the Surface Roughness Tester SJ-301 (Mytutoyo, Tokyo, Japan). Regardless of type and shade of the composite resin, $L^{*}$ values measured in group C were higher than others (p < 0.05), and $L^{*}$ value decreased as the Ra value decreased except B3 shade of Esthet-X. But there were no significant difference in $a^{*}$ values among groups. In control group and SF, highest $b^{*}$ values were measured (p < 0.05), except B1 shade of Esthet-X. Contrast ratio decreased as the Ra value decreased (p < 0.05). With the above results, difference of surface roughness has influence on surface color and translucency of dental composite resins.

In recent years, the companies of electric power equipment for MV and HV classes trend to develop the eco-friendly insulated(solid, eco-gas, air etc.) switchgear which replaces existent SF6 gas insulated switchgear due to environmental problems such as global warming and so on. This paper makes reference to the newly developed Solid Insulated Switchgear (SIS) which uses the eco-friendly material such as epoxy for insulation. The insulation of the solid insulated switchgear (SIS) is composed of an epoxy, vacuum and air. The solid insulated switchgear (SIS) is a slate of the art product. The advantages of SIS are advanced reliability, economical efficiency, safety, maintenance free, reduction of installation area and the protection of environment. The solid insulated switchgear (SIS) is FE Analyzed such as electromagnetic, mechanical, thermal and fluid in order to find the optimal design. Thens SIS has been verified by international standard test. (IEC 62271 - 100 and so on.) As a result of this, the solid insulated switchgear (SIS) has been estimated as an alternative for eco-friendly MV class switchgear.
