According to the building regulation U-value limitation of window is $3.3W/m^2{\cdot}K$ in southern regions, while U-value limitation of wall is $0.35{\sim}0.58W/m^2{\cdot}K$. It means that the energy loss through windows is five times more than it through wall. Therefore, this study analyze how much it has affected building energy rating when the insulation performance of windows and walls is changed by building regulation. In conclusion, in order to obtain 2 rating thermal performance of windows is improved more than 10 percent of U-value limitation and it of wall is improved more than 20 percent. The thermal performance of windows is improved more than 20 percent of U-value limitation and it of wall is improved more than 30 percent to receive 1 rating.

The purpose of this study is to examine the influence of social face sensitivity on vanity and consumption behavior. Questionnaires were administered to 461 college students living in Deagu Metropolitan City and Kyungbook province. Frequency, factor analysis, reliability analysis, regression analysis, and t-test were used for data analysis. Social face sensitivity was categorized into consciousness of being embarrassed, social formality, other consciousness and prestigiousness. Vanity factors were found as physical price, achievement concern, achievement price, and physical concern. Consumption behavior were categorized into 5 factors such as ostentatious consumption, impulsive buying, external information search, brand trust, utilization of internet information and material-oriented. Consciousness of being embarrassed, social formality, and other consciousness, the sub-variables of social face sensitivity had significant effects on achievement concerns and physical concerns. Other consciousness of social face sensitivity had significant effects on all factors of consumption behaviors. There was significant differences in the prestige of social face sensitivity and physical concerns of vanity and ostentatious consumption, impulsive buying, and also in external information search and utilization of internet information of consumer behavior. This indicates that women showed high physical concerns for vanity and ostentatious consumption, impulsive buying, external information search and utilization of internet information of consumption behavior while men care more about prestigiousness of social face sensitivity.

This study classifies vanity into groups, analyzes age differences and categorizes price attitudes toward apparel products. Questionnaires were administered to 461 college students living in Daegu City and Kyungbok province. Data were collected using frequency, factor analysis, cluster analysis, correlation analysis, regression analysis, ANOVA, Duncan-test, and t-test. The findings were as follows. College student vanity was classified into three groups of appearance/ achievement pride, low vanity, and appearance/achievement concern. Vanity showed a significant correlation with sub-variables of age difference and price attitude towards apparel products. Appearance pride and achievement concern (sub-variables of vanity) had a significant effect on the conspicuous of price attitude toward apparel products. Appearance pride and Appearance concern (sub-variables of vanity) had a significant effect on information of price attitude toward apparel products. Gender of college students showed a distinction insub-variables of vanity factors such as appearance concern and price attitude toward apparel products such as information, quality, and using coupons. Male students were distinct in look and health as well as age differences by group; female students were distinct in age perception differences (a sub-variable of age difference). Both male and female students showed differences in conspicuousness (a sub-variable of price attitude) toward apparel products by group.

The limiting equivalent ionic conductances of Li$^+$, Na$^+$, K$^+$, Cl$^-$, and Br$^-$ ions were obtained with TATB[Tetraphenyl Arsonium Tetraphenyl Borate] method from limiting equivalent conductances of LiCl, NaCl, KCl and KBr measured in water-methanol systems by conductometric method. With those values and viscosity of water-methanol systems, the Stokes radii of corresponding ions have been extracted. The latter values corrected by calibration method of Nightingale and supplemented by the crystallographic radii were utilized to calculate the volume of solvation-shell that surrounds ions. The reasonable solvation numbers (h$_{H_2O}$ ＋ h$_0$) were estimated by comparing the values obtained by the various suggested methods. The selective properties of ion solvation were also discussed.

In order to observe a possible effect of CO intoxication on the activities of surfactant, the rabbit war exposed either to 0.1, 0.2 and 0.4% CO gas for two to six hours or 0. 1% CO gas for two hours daily for 1, 3 and 5 days, and the lung extract was prepared. The tension-area diagram of the lung extract was recorded automatically using the modified Langmuir-wilhelmy balance with a synchronized recording system, and the results were compared with control (i. e. : non-CO gas exposed normal rabbits). The results obtained are summarized as follows: 1. The maximal and minimal surface tensions, width of the tension-area diagram at the surface area of 40% in lung extract, and stability index of the normal rabbit lung extracts were $31.6{\pm}3.11\;dynes/cm,\;8.2{\pm}0.56\;dynes/cm,\;21.4{\pm}4.40dynes/cm\;and\;1.12{\pm}0.22$, respectively. 2. The activities of surfactant in the CO gas exposed group did not show any significant change from the control. 3. The above results suggest that CO gas produced no noticeable effect on the surfactant system of the lung.
