This study investigated the effect of brand history, congruity between country of origin and conspicuous consumption of fashion brand, based on the evaluation of customers. The factorial design was constructed as a 3-way mixed design: 2(brand history: presented vs not presented) ${\times}$ 2(congruity between Country of Brand(COB) and Country of Manufacture (COM): congruent vs incongruent) ${\times}$ 2(conspicuous consumption: high vs low). A total of 302 men and women aged above 30 and living in Seoul or within the capital area, were enrolled as subjects. Of these, 26 insincere responses were excluded and a final total of 276 responses were used in the analysis. The statistical analysis included reliability analysis, three-way ANOVA, and simple interaction effect analysis with SPSS 18.0 statistics. Our results indicate that brand history, congruity between COB and COM, and conspicuous consumption had significant effect on the fashion brand preference of consumers. Furthermore, presenting the brand history resulted in higher brand preference. Second, the brand history and conspicuous consumption had a significant interaction effect on brand preference. Consumers with higher conspicuous consumption showed significantly higher brand preference than those with lower conspicuous consumption. Third, congruity between COB and COM and conspicuous consumption had a significant interaction effect on brand preference. However, when COB and COM were dissimilar no significant effect of conspicuous consumption on brand preference was observed.

The purpose of this study was to investigate the effect of use motivation type for mobile phones and the degree of loss perception related to mobile phone consumption consciousness in adolescents. The subjects of this study were 503 students in middle and high school in Daegu. A questionnaire was used for the survey. Factor analysis, cluster analysis, and MANOVA were employed for the data analysis and the $Scheff\acute{e}$ test was used for post-hoc analysis. The results are as follows: First, there are significant differences in mobile phone consumption consciousness in all sub-dimension areas according to use motivation type for mobile phone. Second, adolescents with high economic loss perception for mobile phones show high consumption consciousness in sub-dimension area, and adolescents with high academic loss perception show high relation-oriented consumption consciousness. Adolescents with high physical loss perception show high health-oriented, relation-oriented, and function-oriented consumption consciousness. Adolescents with high psychological loss perception, on the other hand, show high relation-oriented consumption consciousness. Third, there are significant differences in mobile phone consumption consciousness according to use motivation type for mobile phones and the degree of overall loss perception. However, there are no significant differences in the mobile phone consumption consciousness according to use motivation type for mobile phones and the degree of overall loss perception.

The purpose of this study is to investigate the relation among adolescents' school consumer education, cell phone consumption behavior and satisfaction with cell phone consumption life. Finally, this study aims to find right ways for leading to adolescents' reasonable consumption life and improving the school consumer education. A survey was conducted to the second grade students 430 of middle school residing in Seoul and the Capital area. As the result of examining the relation among school consumer education, consumption behavior, and consumption life satisfaction, the learning of 'information analysis and decision making process' has a positive effect on 'reasonable purchase and active problem-solving' behavior, and the learning of 'consumption culture' on 'active problem-solving and ethic use' behavior, the learning of 'problem-solving and rights and responsibilities' on 'ethic use' behavior. In addition, it shows that 'ethic usage behavior' in consumption behavior has a positive influence on 'relation satisfaction', and 'reasonable purchase' behavior and 'active problem-solving' behavior on 'practical usage satisfaction'.

The millennial generation, which has emerged as one of the strongest influence and consumption power, pursues happiness of the present centering on "I"; consumes luxury products for themselves. The purpose of this study was to evaluate how the narcissism and materialism of the millennial generation affect the compensatory consumption of luxury products in negative situations and the moderating effect of self-control. This study included 315 millennial males and females living in Seoul and Gyeonggi area. Frequency analysis, reliability analysis, multiple regression analysis, and hierarchical regression analysis were conducted using SPSS 25.0 statistical program. Based on our findings, narcissism and materialism had a statistically significant effect on compensatory consumption under positive situations. However, while materialism had a statistically significant effect on compensatory consumption under negative situations, narcissism did not have a statistically significant effect on compensatory consumption under negative situations. Notably, self-control had a moderating effect in the influence of materialism on compensatory consumption under negative situations; narcissism did not. This study holds academic significance as the concept of compensatory consumption and self-control can be applied to the apparel study. Moreover, this study provides practically significant ideas on compensatory consumption and therefore marketing of luxury brands, based on consumers' characteristics.

Driving pattern of gasoline passenger car was measured and analyzed at some areas(6urban area routes, 4 radial routes, 4 circular routes)in Seoul city. Measured items were vehicle speed, engine speed, intake manifold vacuum, and fuel consumption. Driving pattern data were reappearanced with engine dynamometer. Results of this investigation might be summarized as below; 1. When we compared urban area route with radial or circular route in rush hour, it was found that the average vehicle speed was measured to be lower about 25% and fuel consumption to be higher about 12% in urban area route. 2. Average vehicle speed was measured to be higher about 30% and driving resistance output to be higher about 25% in non-rush hour, but average fuel economy was increased a little. 3. On the bases of average fuel economy and characteristics of exhaust emissions, optimum driving vehicle speed was found about 60 km/h in the 4th(top)and about 40km/h in the 3rd in driving of experimental engine. 4. Idling frequency and exhaust emissions of CO,HC were related to idling closely. But exhaust emission of NOx, which had nothing to do with idling frequency, had relation to acceleration time ratio.

Solar energy, which is one of renewable energy, would be the most useful resources that can be applied to making energy recycling villages without using fossil energy. This study analyzed energy potential on solar energy considering weather condition in three traditional villages and compared with energy consumption surveyed. A photovoltaic system having 3.0kWp capacity of unit module can generate 182.5%, 96.1% and 170.9% of the yearly mean consumption of electric power in Makhyun, Boojang, and Soso, respectively. A flat-plate solar collector having $2.64m^2$ area of unit module can generate warm water of $142{\ell}$/day, $89{\ell}$/day, and $173{\ell}$/day, respectively in three study villages. In Makhyun and Soso, photovoltaic power and warm water produced by solar energy were sufficient to supply required amount of electric power and warm water. However, both electric power and warm water produced by unit solar module were not sufficient in Boojang area, and so it is required to increase the module area by more than 50%. According to the results of this study, the appropriate combination of energy resources can be applied to rural green-village planning if the characteristic of energy potential for each local area is considered.

The partial product matrix (PPM) of a parallel squarer is symmetric. To reduce the depth of PPM, it can be folded, shifted and rearranged. In this paper, we present an area-efficient squarer design method using new partial product rearrangement. Also, a fixed-width squarer design method of the proposed squarer is presented. By simulations, it is shown that the proposed squarers lead to up to 17% reduction in area, 10% reduction in propagation delay and 10% reduction in power consumption compared with previous squarers. By using the proposed fixed-width squarers, the area, propagation delay and power consumption can be further reduced up to 30%, 16% and 28%, respectively.

This study was conducted to assess the nutrient intake and diet quality of college students in Seoul. Dietary survery data were obtained by 24-hour recall method from 774 students, 553 males and 191 females. Mean daily intake of energy was 2,480kcal with 56.4% of energy intake from carbohydrate, 14.6% from protein, and 25.5% from fat. Percentage of fat was higher than mean values of National Nutrition Survey(NNS), adults in rural area or younger students in previous studies. Mean daily intakes of calcium and vitamin A did not meet RDA levels in both sexes and intake of iron in females was insufficient to meet RDA level. The percentage of animal food to total food intake was 25% and consumption of meat, beverage and milk group was higher than those of National Nutrition Survey(NNS). When the consumption of 5 major food groups(grain, meat, milk, fruit, vegetable) were evaluated, 22% of students consumed all 5 groups and 47% consumed 4 groups, which show more balanced food group intake than adults in rural area. Food groups which were omitted frequently were milk and fruit. These results show that college students in Seoul consume better diet than subjects of National Nutrition Survey(NNS) or adults in rural area. However, high fat intake, low calcium and vitamin A intake and low iron level in women were observed. Majority(78%) of students had at least one food group omitted in their diet. Appropriate nutrition education may help to improve the quality of diet in these students.
