Various types of health functional foods (HFF) are popularly used among middle-aged. We surveyed 946 middle-aged in Korea for HFF use and significant variables for their HFF use including demographic characteristics, health related variables and nutritional beliefs. The use prevalence of HFF was 58.9%, and among all types of HFF, red ginseng products were taken most frequently, followed by nutritional supplements, ginseng products > mushroom products. HFF was taken more frequently in subjects from high monthly family income (p < .001), and in those from families with a high socioeconomic status (p < .001) in comparison to each corresponding group. Mean age of users was higher than nonusers (p < .001). Self concern about health (p < .001) and usage ratio of HFF by family (p < .001) were higher in users than in nonusers of HFF. Total dietary assessment score was not different in two groups, and users had a more positive view concerning the potential health benefit of HFF than nonusers (p < .001). Most users of HFF took HFF when they were healthy (52.8%) and experienced a little effect through the HFF use (51.2%). Most users of HFF obtained the information on HFF through family and relatives (30.5%) and most of them purchased HFF at pharmacy or oriental medicine clinics (44.5%). HFF users preferred multivitamin and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread use of HFF and inappropriate usage of HFF among subjects, the proper use of these products for the contribution to their optimal nutrition and overall health is a subject that should be formed through practical nutrition education considering the various variables affecting their HFF use.
The field of textile and fashion is regard to be sensitive to trend, however, the professional fashion information planning company for trend forecasting has not settled down in Korea. This study was designed to propose systemizing for fashion trend information planning in domestic fashion information service market. The empirical research was conducted by analysing in-depth interview data and news-scrap contents about each fashion information planning company. The result are as follows; First, fashion information service showed a little difference according to the type of fashion information companies, but they provided not only general fashion trends but also external market environmental information, survey-based consumer information and various segmented market research reports including academic information. Second, the fashion information planning process is largely divided into 3 stages; trend analysis, trend forecasting, trend application. The trend application step is the stage which connects the fashion information service industry to the fashion business. Thirdly, as a result of the competitive power evaluation for fashion information planning, the domestic fashion information planning companies came to reveal the fact that the possibility of carrying out and information analysis power were weak, however, how to present trend information had a relatively competitive. Consequently, this study is expected to play a role in understanding the importance of fashion trend information, and further ahead it would be helpful to organize the curriculum of fashion information planning subject in order to educate the future fashion executives.
This study was undertaken to investigate the dietary behavior and sugar intake of korean school children. The subject were 131 school lunch program children and 149 non school lunch program children lived in Soung Nam city. Sugar intake, food intake, dietary behavior and anthropometric measurement were studied through personal interview using 24-hour recall dietary data and records. Total daily energy and nutrient intake of children were higher than RDAs except for intake of Calcium and vitamin A. The nutrients intake of school lunch program children were significantly higher than that of non school lunch program children (p<0.05). The range of daily sugar intake was 10 g to 220 g and the total daily sugar intake was $63.0{\pm}37.4\;g$. Sugar intake of school lunch program children ($51.4{\pm}25.7\;g$) was significantly lower than non school lunch program children ($73.1{\pm}42.9\;g$) (p<0.0001). The more sugar intake increase more intake of Energy, Fat and Carbohydrate. The result of stepwise multiple regression analysis using the sugar intake of children as dependent variable, energy, vitamin $B_2$, protein, niacin, calcium school lunch program, education of fathers are significant explanatory variables, explaining 44.8% of variation. Result of this study suggest that school lunch program is desirable for good dietary behavior and decreation of sugar intake of school children.
This paper examines the effect of private tutoring expenditures on academic performance of middle school students in South Korea, using data from "Analysis of the Level of School Education and Its Actual condition: Middle School". In the face of endogeneity of private tutoring expenditures, the paper employs an instrumental variable (IV) method and a nonparametric bounding method. Using both methods we show that the true effect of private tutoring on middle school students remains at most modest in Korea. The IV results suggest that a 10 percent increase in tutoring expenditure for Korean, English and math raises a student's test score of the subject at the largest by 1.24, 1.28, and 0.75 percent, respectively. The bounding results also fail to show evidence that an increase in tutoring expenditure leads to economically and statistically significant improvements in test score.

In this study, we propose an antibacterial cosmetic case using UV wavelengths. UVC have excellent antibacterial strength in terms of economics and convenience. The purpose of experiments was to prove it and to select a suitable permeability material. In experiments, UVA, UVC machanics and the competitor product were used to measure and compare the antibacterial strength of antibacterial cosmetic case using UV wavelength. S. aureus, a gram-positive strain, was used subject to the experiment, and the antibacterial strength measured and compared the number of colonies using the plate count technique. As a result, both UVA and UVC showed antibacterial activity, and UVC showed the most powerful antibacterial activity. In Conclusion, the Quartz glass was the most suitable of the permeable materials, but the more thick the examined quartz material became the less antibacterial strength.

Pedestrian environment not only affects the quantitative degree in pedestrian movement, but also an impact on the local economics and environment that speaks within the greater dialogue of the qualitative life in an urban context. Recent urban planning issues have matured from a linear street development to a conversion of pedestrian friendly streets that synchronizes the entire pedestrian movement structures as a whole. Subject cases, Myung-Dong and Kwanchul-Dong, were selected from time regulated pedestrian streets in Seoul. Analysis of these streets was done through field studies and interviews. From the research, the outcome was helpful in providing the developers a greater perspective with the pedestrian movement structure that is not confined to a certain parameter, but in a larger scale within the urban environment. It was also useful in justifying ambiguous locations of pedestrian-only streets and crosswalks. Also, It aided in planning optimal scheme that concurs with the predictable pedestrian movement.
