The responses of 318 female college students living in Seoul and surrounding vicinities were collected and analyzed. Inner wear, blue-jean pants, coat were selected as representing each clothing product characteristics. Frequencies distribution, regression and correlation coefficient were utilized for statistical analysis. Results are as follows. 1. The type of perceived risk and risk reduction behavior differed according to product characteristics of clothing. Physical and performance risk were more highly perceived for the purchase of innerwear. However, for the purchase of jean pants and coat, socio-psycho-logical and economic risk were also perceived highly because the rate of fashion change, social symbolism, and coordination with other clothing items become more important characteristics. To reduce perceived risk, dependency on past purchase experiences and shop-ping were mostly preferred method regardless of product characteristics of clothing. 2. Risk type as determinant variables for predicting overall risk differed according to product characteristics of clothing. But fashionability and usefulness were common determinant risk variables, which identifies typical characteristics of clothing product.

The objective of this field research is to determine consumer's fashion sense and provide helpful information to manufacturers when planning designs and merchandizing strategies. This study's purpose was to observe what was being worn, colors and tones. The method of research was fixed point observation using digital photos. The subjects of the research were female college students, 18-22 years old. The T-shirt has become the representative item for casual and comfortable wear by the female college students. Pants and blue jeans were worn more often than skirts as a lower garment. This shows that the students think about their activities when choosing a lower garment. The majority of these students chose clothing that functioned well for their school activities. Among students that wore skirts about half wore a functional knee length while the other half wore a more fashionable mini-skirt. These students appear to care about both fashion and function. Blue was especially popular, with 70.4% of all lower garments being blue. This effect makes the body look thinner and may be one reason why blue is so popular. White is a popular color as an upper garment. White upper garments are easily matched with any color, while blue upper garments coordinate well with similarly colored blue lower garments. The distribution of upper garment color is significantly influenced by the seasons. Blue jean tones were many and varied, while upper garments were mostly weak tones and bright tones of pale, light and soft.

This study was performed to analyze the wearing practice and the purchasing characteristics of jeans in order to offer basic data to produce superior jeans made of denim with small flexibility and to improve the wearing comfort. The questionnaire were 236 Korean women from the age of 10th to 50th. For data analysis, descriptive analysis and crosstabs were used. The results were as follows, in the purchasing characteristics, when the women of 10th to 30th decided to purchase jeans they considered fashion, design and price rather than wearing comfort. But the women of 40th to 50th considered that wearing comfort is the most important factor. The 10th is found the best preferred jean is wide straight style, the 20th is straight style, the 30th is boots cut style and the 40th to 50th is straight style. In wearing practice, there was a difference among age groups on the region that felt uncomfortable when wearing jeans. As the age increases, the abdomen size also increases. Most people answered that they mend jeans after purchase for length, without any relation with age. The reason why consumers prefer jeans with middle length between the crotch and waist and also purchase jeans with a short length is because they look refined and neat. This informs us that the short length between the crotch and waist does not match with ease and comfort, which are the images of jeans in the past. Recently premium jean brands are competing to show Low Rise Jeans, which seems like a Premium Jean=Low Rise Jean formula is created. Some manufacture companies are recklessly copying foreign designs that does not fit Korean's body shape. However, as mentioned in this study results, there is a clear difference between designs that they think consider as aesthetic and functional. Therefore, it is considered necessary for developing designs for jeans that can satisfy both aesthetic appreciation and functions for Korean consumer's body shape and each age group.

The above-mentioned findings illustrated that both male and female students regarded blue as the original color of jeans, but they wanted to wear jeans in colors other than blue. In the past, jeans were considered masculine and unisex, but they viewed jeans as an apparel that was comfortable to wear and made it easier to move. Female students had a higher tendency to be fashionable than male students, and their preference for jeans was consequently different. Jeans manufacturers should take those characteristics into account to produce products in different colors and form.

Coffee is one of the top selling products in the world. There are various coffee bean species around the world. Among them, Coffea Arabica is the most popular species. However, there are few studies on the metabolites of coffee beans so far. This study demonstrates effects of the planted regions on the metabolite concentrations of coffee beans. The metabolites of coffee beans can be affected by growing area even although same species are grown. Accordingly, we studied coffee bean metabolites extracted from the same species in different regions (The brand names, Kona from Hawaii, Mocha Matari from Yemen, and Blue Mountain from Jamaica) by using mixed solvent of methanol: water: chloroform. A comparative analysis by NMR spectroscopy was performed and the statistical techniques were used to figure out the differences. As a result, we found that chlorogenic acid, caffeine, citrate, and sucrose mainly contributed to the separation of the three groups. When compared with Kona and Blue Mountain, concentrations of chlorogenic acid, caffeine, and sucrose in Mocha Matari were observed to be relatively down-regulated. In addition, compared with the two other groups, concentration of citrate in Kona was observed to be up-regulated.

Two-photon fluorescence microscopy was performed on the enamel-dentin junction area of a human tooth using a femtosecond pulsed laser. We obtained a clear image contrast between the bright dentin and dark tubules with the autofluorescence generated from the endogenous fluorophores in dentin. The autofluorescence shows a broad spectrum due to complex cross links between dentinal collagens, which extend from blue to orange wavelengths (470-590 nm), but a gradual autofluorescence loss in photobleaching was observed for a long-term exposure under strong excitation. For increasing excitation power, we found that two-step decay becomes significant in the spectrally integrated autofluorescence.

Recently Korean construction companies have started launching into the world beyond the Middle East to Southeast Asia. Launching into Central Africa has emerged as the blue chips; therefore, it is needed to study the local people and culture of Central Africa. However, launching Korean construction companies into Central Africa may cause some problems between Korean and African construction laborers' thinking. Therefore this comparative analysis of Korean and Central African construction laborers' job consciousness can provide to Korean companies a minimum understanding of these kinds of problems to expect while launching into Central Africa and so using this analysis as a basic data to supply them.
