The purposes of this study were to classify the types of consumers' emotion experienced in-store by shopping motivation and to examined the effects of store environmental factors on emotion and on shopping behavior. The questionnaires were administered to 330 women shopped in department store. Data from 299 women were analyzed by using frequency t-test and regression analysis by SPSS for windows PC program The results of this study were as follows : 1. The consumers' emotion experienced in -store were composed of five factors. But it could be divided by positive negative factors. 2. There was not significant difference in positive emotion between he Product Pu-rchasing Motive Group and the Window Shopping Motive Group. But there was significant difference n negative emotion between two groups. 3. It was found that the effect of environmental factors of apparel store on emotion was significant in both groups. Especially salespeoples' pressure significantly influenced negative emotion in both groups. 4. The emotion experienced in -store significantly influenced clothing shopping behavior.

Discomfort glare from windows is an important issue in window and daylighting design. This study aims to investigate the effect of luminance difference between the lower and the upper part of a large glare source. Experiments were conducted using a luminous body divided into two parts, the upper part and the lower part. The degree of discomfort glare from the luminous body was examined. The result shows that the part with lower luminance is perceived as a glare source when the part has higher luminance then the background luminance. The degree of discomfort glare was estimated for the experimental conditions, and compared to the observations. The estimation was made using two methods: one summed the glare sensation for each section, and the other used the average luminance of the whole luminous body. The result of the comparison shows that the method using the average luminance has approximate values to the observations. Consequently, the use of the average luminance was proposed for evaluation of discomfort glare from non-uniform large glare sources.

The effect of wtlitc light on unaeraten growth of Baker's yeast and the accompanying ethanol production has been studied in a batch process at 27$^{\circ}C$. Over the 80-hour period of the Champagne yeast process without pH control, the cull growth was inhibited by the fluorescent light. Another observed difference between the runs is that the drop and subsequent rise in redox potential occurred much sooner in the fermentation with light than in the fermentation without light. This preliminary study indicated that ethanol production could be enhanced by light as the cell concentration is repressed. The possible pathway, shift of the sugar substrate toward ethanol and away from cells was manifested by another difference as well. As observed under the microscope, many of the yeast cells grown under light budded without dividing by the normal fission process as they did in the dark. Furthermore, the undivided and branched (light grown) cell did not agglutinate at the end of the fermentation process as did the distinct spherical (dark grown) cells.

The purpose of this study was to investigate the effect of brainwriting instruction on students' experimental design and scientific communication ability in elementary science class. For this purpose, a brainwriting learning for science class was developed and applied. The objects of this study were the 4th graders of both an experimental class (24 students) and a comparative class (24 students) at the N elementary school located in Incheon city. The results of the study were as follows; First, as a result of examining the difference in the experimental design ability between experimental group and comparative group, the experimental group showed higher than the comparative group, it was statistically significant difference(p<.05). Second, a scientific communication ability of the experimental group after applying this program was higher, it was statistically significant differences (p<.05).

Objectives The purpose of this study was to analyze the difference of cold-heat pattern according to sasang constitution. Methods 3891 subjects were joined in this study. The sasang cinstitution diagnosis were proceeded by sasang constitution experts. The questionnaires and anthropometric measurements of the subjects were collected. Results The effect of gender and body mass index on the cold-heat pattern according to sasang constitution were significant. The effect of age on the cold-heat pattern according to sasang constitution were not significant. The distribution of short form-12 and blood test on the cold-heat pattern according to sasang constitution were significant. Conclusions There were significant different distribution of cold-heat pattern asscording to sasang constitution by gender, body mass index, short form-12, blood test.

In this study, the color reproduction algorithm considering both of luminace and chromaticity of the background light is presented and tested to BT-H 1450 monitor(Panasonic). In the case of neglecting the background effect, the Macbeth ColorChecker's 24 colors are reproduced with the average color difference ${\Delta}E_{ab}^{*}$ more than 9.0. By using this method, the average color difference ${\Delta}E_{ab}^{*}$ is decreased less than 1.0. From this study, we can find that both of luminance and chromaticity of background light are very important factors in the color reproduction on a CRT display.

A compact scanning confocal microscope has been constructed using a quad-detector in a CD-player. The variation of error signal on depth which obtained by a quad-detector is used in the scanning confocal microscope. Bipolar error signals, which is sensitive near a focus, give a surface following effect whiout following the surface. In the case of small depth difference, the difference of materials through the reflection signal has been identified. The image which uses reflection signal only, has been obtained with the same setup. And, the results obtained in two different way were compared and analyzed.

Extensive studies have been conducted on thermal conductivity of bentonite buffer materials, as it affects the safety performance of barriers engineered to contain high-level radioactive waste. Bentonite is composed of several minerals, and studies have shown that the difference in the thermal conductivity of bentonites is due to the variation in their mineral composition. However, the specific reasons contributing to the difference, especially with regard to the thermal conductivity of bentonites with similar mineral composition, have not been elucidated. Therefore, in this study, bentonites with significantly different thermal conductivities, but of similar mineral compositions, are investigated. Most bentonites contain more than 60% of montmorillonite. Therefore, it is believed that the exchangeable cations of montmorillonite could affect the thermal conductivity of bentonites. The effect of bentonite type was comparatively analyzed and was verified through the effective medium model for thermal conductivity. Our results show that Ca-type bentonites have a higher thermal conductivity than Na-type bentonites.

With CB data in South Korea, this study examines whether the credit risk of borrowers changes when the regulation on bank mortgage supply is relaxed. We analyze the effect of deregulation on LTV and DTI limits in the Seoul-metropolitan area in August 2014 with a difference-in-difference approach. We find that the probability of delinquency is lower in the Seoul metropolitan area after the deregulation than in other urban areas. The effect is noticeable among low-income and low-credit borrowers. We also find that borrowers change their debt structure to reduce the interest costs utilizing their improved access to bank mortgages. The findings suggest the necessity to consider the burden of the high interest costs of unsecured loans for debtors with low incomes and low credit ratings in designing housing finance regulations.
