The crucibles of Baekje Kingdom from the Ssangbukri Site which were used for glass and metal melting had light brown, grayish blue and grayish brown colored bodies. In thin section, the crucibles contained numerous quartz grains and pottery fragments. The surface was covered with fine grained quartz for thermal resistance. Based on decomposition of mica group minerals and formation of mullite detected by X-ray diffraction analysis, it was inferred that all crucibles have been fired over $1,000^{\circ}C$. It was also found that firing temperature has exceeded $1,100^{\circ}C$ in some crucibles because feldspar was not detected. The maximum temperature was assumed at $1,200^{\circ}C$. The magnetic susceptibility values and geochemical characteristics sorted out the crucibles into two groups that differed from the characteristics of the local soils. This reflected geological setting of the site where the alluvium was formed from two kinds of surrounding rock masses, granite gneiss and biotite granite. However, the local soils had similarities with the crucibles in weathering degree and geochemical behavior of major elements. In consequence, it was considered that the raw clay of the crucibles was supplied from the local area of the site.

A numerical analysis was performed on magnetic field effects of silicon melt motion in Czochralski crystal puller. The turbulent modeling was used to simulate the transport phenomena in 18' single crystal growing process. For small crucible angular velocity, the natural convection is dominant. As the crucible angular velocity is increased, the forced convection is increased and the distribution of temperature profiles is broadened. The cusp magnetic field reduces effectively the natural and forced convection near the crucible and the temperature profiles of the silicon fluids is similar in the case of conduction.

The purposes of this study were to classify high school male and female students according to body cathexis and appearance interest, and understand their appearance management behaviors and clothing benefits sought. The results were as follows : First, the body cathexis of high school students were low, and female students had lower body cathexis than male students especially in the lower halves of bodies. The appearance interests of students were high, but female students had higher appearance interests than male students. Second, male students were classified by body cathexis and appearance interest into three groups with high, middle, and low body cathexis and appearance interest, and most of them belonged to the middle group. Female students were classified into four groups(with high body cathexis and appearance interest, with high body cathexis but low appearance interest, with low body cathexis but high appearance interest, and with low body cathexis and appearance interest) and most of them belonged to the group with low body cathexis but high appearance interest. Third, male students in groups with high and middle body cathexis and appearance interest showed more appearance management behaviors than those in the group with low body cathexis and appearance, while management behavior, followed by the group with low body cathexis but high appearance interest, that with high body cathexis but low appearance interest, and that with low body cathexis and appearance interest. Fourth, female students sought more aesthetics, fashionability, brand, and price in clothing coml)wed to male students. Male students in high and middle groups tended to seek more aesthetics, fashionability, and brand than those in the low group, but all three groups didn't consider price benefit sought. Female students with high body cathexis and appearance interest tended to seek more aesthetics and fashionability than those in other three groups. And only the group with low body cathexis and appearance interest didn't consider brand benefit sought. All four groups were found to consider price benefit sought. I hope that results of this study help teachers to guide students' clothing life more positively by understanding their appearance management behaviors and clothing benefits sought than to control negatively.

This study focused on the material characteristics and archaeometric relationship between the molten glass and bronze materials within the crucibles and gilt-bronze Bodhisattva statue excavated from the Ssangbukri site in Buyeo, Korea. Yellowish green to red brown vitreous material in the crucibles was identified as lead glass which contained scarce amount of BaO, and low $Al_2O_3$ and CaO. Metallic molten material was identified as bronze of copper-tin-lead alloy with low amount of impurities that indicated well-refined materials. Also, cassiterite was used for raw metal ore of tin. The Bodhisattva statue consisted of major copper with trace impurities in the core metal, and gold amalgam in the gilded layer. Though lead isotopic analysis showed contradictory results in each lead glass, bronze and Bodhisattva statue that required further examination, it could be stated that the statue was made in the Ssangbukri site based on the high-level technical skills of bronze production.

A brown ring (hereinafter referred to as BR) on the inner surface of a quartz glass crucible used in the manufacturing process of a silicon ingot for semiconductor wafers was studied. BR is 20~30 ㎛ in size and has an asymmetric brown ring shape. The size and distribution of BR were different depending on the crucible location, and the size and distribution of BR were the largest and most abundant in the round part with the highest crucible temperature during Si ingot growth. BR contains cristobalite, which has a higher coefficient of thermal expansion than quartz glass, so it is considered that surface cracks appear. The color development of BR and pin holes are presumed to be due to oxygen vacancies.

This study attempted to verify the influence of appearance satisfaction on interest in eye makeup and makeup care behavior in female consumers and provide basic data which are needed to plan marketing strategies and develop cosmetics in the cosmetics market. For this, a questionnaire survey was performed against adult women in their 20-50s from the capital region. A total of 399 copies were used for final analysis, and the results found the followings: First, differences were found in appearance satisfaction, interest in eye makeup and makeup care behavior by general characteristics. In other words, interest in eye makeup started with 'self-care', showing interest in chasing a trend. Second, concerning the effects of appearance satisfaction on interest in eye makeup, as the respondents were more satisfied with their facial contour, they were more interested in eye makeup. Third, in terms of the influence of appearance satisfaction on eye makeup care behavior, as they were more satisfied with their skin conditions, trend-setting makeup care behavior increased. Consequently, increase in appearance satisfaction enhanced interest in eye makeup, having an influence on makeup care behavior.
