The purpose of this study is to understand the characteristics of intergenerational consumption-oriented attitude and consumer role performance. Major findings are as follows; 1) There is significant difference between the consumption-oriented attitudes of respective generations. The means of New generation are higher than the other generations especially in amusemental consumption-oriented attitude and tenacious consumption-oriented attitude. Baby-boomer generation is more interested in consumption than any other generation and has a rational consumption-oriented attitude. The older generation is passive to consumption and their consumption-oriented attitudes are those of amusement. 2) There is also the significant gap between the consumer role performance of generations. The means of new generation and older generation are higher in consumer role performances than other generations and are especially doing better in the roles of estimator and manager. 3) consumption-oriented attitudes illustrate the variation of consumer role performance and the stronger the rational or tenacious consumption-oriented attitude, the higher the consumer role performance and the higher the rational or tenacious consumption-oriented attitude, and the lower the passive consumption-oriented attitude, the higher the consumer performance. In purchaser and manager role, the more positive the consumption and the higher the rational consumption-oriented attitudes, the better the consumer role performance.

The world population is consuming more than 1/3 of the total energy for heating housings. Particularly in our country, 21% of the consumption energy is occupied by building section. Therefore, it is necessary to increase the energy efficiency in buildings, thus promoting a comfortable residential environment while minimizing energy consumption. Accordingly, this study presents considerations for implementing high-insulated and airtight passive houses. This study selected four houses with passive house design applied, performed building energy performance through PHPP2007, a German passive house design simulation program, and compared the building-specific heat loss and heat gain. As a result, the most vulnerable part to heat loss was turned out to be a window and the heat loss was caused by outer wall, roof, and ventilation. Accordingly, for the implementation of passive house, it is necessary to make a careful plan and airtight construction that are complementary to various parts through the energy performance analysis started from the design phase.

An analysis on a passive current sharing characteristics of a multi-phase synchronous buck converter is presented. The passive current sharing method is simple but its characteristics depend on the converter equivalent resistance and PWM uniformity. In this paper, the load sharing and power consumption of the passive current sharing system for the converter equivalent resistance and duty ratio inequalities are investigated through the simulation and experiment.

This research aims to examine the pro-environmental food consumption behavior of two groups; the housekeepers and the restaurant cooks. The rationale for choosing these groups as target of research lies in the fact that they are expected to be the most active subject for enhancing the desirable culture of food consumption, through their close involvement in the whole process of food consumption in society. This study assumes the four areas of activity to be the meaningful categories in the investigation of the pro-environmental food consumption behaviour; planning of menu and purchasing the food materials, cooking, eating, and disposal of the leftover. By using these four categories, we attempt to provide with the empirical typology of pro-environmental food consumption behaviour and the analysis of the relations of it with socio-demographical variables. Their pro-environmental behaviors are divided into four types: $\circled1$ The positive awareness of pro-environmental cooking and eating, $\circled2$ The positive awareness of pro-environmental food consumption behavior, $\circled3$ The passive awareness of pro-environmental cooking and eating, $\circled4$ The passive awareness of pro-environmental food consumption behavior. There is no significant difference among the numbers of the cases that belong to each behavioral type. Seen in overall, however, we can say that the larger number of the cases belong to the passive type of behavior. Two socio-demographical variables of tole housekeepers and the restaurant cooks show significant corelations with the behavioral types of pro-environmental food consumption with the confidence level P<0.05, but there is no significant co-relations in other variables like gender, marital status, age, income, Engel coefficient, education. We also found that there is no great gap between the housekeepers and the restaurant cooks in their positive awareness of pro-environmental food consumption, the percentage of each group belonging to the type being 51.9% and 48.1%, respectively, but that the former shows much greater number than the latter in belonging to the passive awareness type of the pro-environmental food consumption, 75.3% and 24.7%, respectively. Although the restaurant cooks can be said to be more ego-friendly than the housekeepers, if we consider the rapidly growing trend of outgoing-diner, more efforts should be exerted to develop the education and advertisement program for enhancing the restaurant cook's pro-environmental awareness and propagating the desirable food consumption cloture.

This study examined the effect of beauty involvement on self-satisfaction by conspicuous consumption tendency groups. A questionnaire method was used for this study. The subjects of this research were females in their 20s~50s. We distributed 580 questionnaires ets; constantly, 554 sets were used in the final analysis. Data were analyzed by factor analysis, ANOVA, cluster analysis, Cronbach's alpha coefficient and multiple regression analysis. Beauty consumption behavior factors were classified with hair styling, skin management, make-up and body shaping. Self-satisfaction factors were classified with living, appearance, economic and interpersonal relation. This study classified 4 conspicuous consumption groups (active, passive, syntonic and individuality & frugal group). The active conspicuous consumption group was unsatisfied with most of the self-satisfaction factors. The passive conspicuous consumption group was more interested in skin management factors than other factors. The syntonic conspicuous consumption group was interested in make-up, body shaping and skin management in order to provide a positive impression to other people. The individuality & frugal group was most interested in body shaping that could be achieved at low cost through exercise and diet.

The purpose of this study was to explore the effects of adolescent consumers' attitudes toward money and conspicuous consumption on unethical consumption behavior in commercial transactions. The main survey was conducted targeting 290 middle and high school students. As a result of this research, first in the case of adolescent's attitudes toward money, the symbol for happiness and success was 3.11 and the means of control was 1.77 respectively. The level of conspicuous consumption behavior was 2.75 and the level of unethical consumption behavior scored as passive unethical consumption behavior was 1.38 while the active unethical consumption behavior was 2.10. Second, in the case of the attitude toward money as a means of control, it differentiated according to the level of living and the amount of allowance. Conspicuous consumption behavior differentiated according to the amount of allowance and the father's education. Active unethical consumption behavior showed a difference according to the amount of allowance and the father's education. Multiple linear regression analysis conducted to identify relative effects of the variables that affect unethical consumption behavior, in case of passive unethical consumption behavior, showed that conspicuous consumption(${\beta}$=.23, p<.01) and attitudes toward money as a means of control(${\beta}$=.29, p<.001) with an explanatory power of 18%. In the case of active unethical consumption behavior, showed that sex(${\beta}$=.16, p<.05), father's education(${\beta}$=-.15, p<.05), attitudes toward money as means of control(${\beta}$=.18, p<.5) and conspicuous consumption(${\beta}$=.36, p<.001) with an explanatory power of 26%.

This study addresses the effectiveness of TEC(Thermoelectric cooler) application for spacecraft thermal control. The required radiator area and power consumption characteristics of active thermal control using TEC are compared with the passive control at BOL and EOL through unsteady thermal analyses by calculating external heat fluxes. When the component operating temperature is low enough in TEC active control, the required radiator area can be smaller than the passive thermal control. TEC also needs less power consumption than the passive control under the condition that the temperature of cooling pars is low enough and/or the design temperature margin of the components is narrow enough.

This study classifies conspicuous consumption groups and the difference of fashion involvement and selfsatisfaction by each group. It also examined the effect of fashion involvement on self-satisfaction by each group. A questionnaire method was used for the study method and the subjects of the study were females in their 20s-50s. A total of 580 sets of questionnaires were distributed and 554 sets were used for the final analysis. Data were analyzed by factor analysis, t-test, ANOVA, factor analysis, cluster analysis, Cronbach's alpha coefficients, and multiple regression analysis. The results of this study were as follows: First, this study classified 4 groups of active conspicuous consumption, the group of passive conspicuous consumption, the group of syntonic conspicuous consumption and the group pursuing individuality & frugal consumption. Second, as a result of the examination of the impact of fashion involvement for each group with a propensity for conspicuous consumption on their self-satisfaction, it was found that the sex appeal of fashion involvement had no significant impact on the economic satisfaction in the group of active conspicuous consumption, and had no significant impact on all elements of self-satisfaction in the group of passive conspicuous consumption. It was also found that social symbolism had a negative impact on satisfaction with looks in the group of syntonic conspicuous consumption, and the physical complementation and directions of looks had a negative impact on satisfaction with living, the social symbolism on satisfaction with looks and the syntone on satisfaction with looks in the group of pursuing individuality & frugal consumption.

In this paper, Passive Telemerty RF Sensor System using Unscented Kalman Filter algorithm(UKF) is proposed. General Passive Telemerty RF Sensor System means that it should be "wireless", "implantable" and "batterless". Conventional Passive Telemerty RF Sensor System adopts Integrated Circuit type, but there are defects like complexity of structure and limit of large power consumption in some cases. In order to overcome these kinds of faults, Passive Telemetry RF Sensor System based on inductive coupling principle is proposed in this paper. Because passive components R, L, C have stray parameters in the range of high frequency such as about 200[KHz] used in this paper, Passive Telemetry RF Sensor System considering stray parameters has to be derived for accurate model identification. Proposed Passive Telemetry RF Sensor System is simple because it consists of R, L and C and measures the change of environment like pressure and humidity in the type of capacitive value. This system adopted UKF algorithm for estimation of this capacitive parameter included in nonlinear system like Passive Telemetry RF Sensor System. For the purpose of obtaining learning data pairs for UKF Algorithm, Phase Difference Detector and Amplitude Detector are proposed respectively which make it possible to get amplitude and phase between input and output voltage. Finally, it is verified that capacitive parameter of proposed Passive Telemetry RF Sensor System using UKF algorithm can be estimated in noisy environment efficiently.
