학생은 미래뿐만 아니라 현재의 소비자로서 합리적인 의사결정을 통한 소비문화가 요구된다. 하지만 학생의 소비문화와 학교의 소비교육, 가정교육은 문제점을 안고 있다. 학생들은 물건의 필요성이나 용도, 금전상황, 가정상황 등을 전체적으로 고려하여 구매하기보다는 비계획적이고, 즉흥적이다. 학교에서는 교사들이 학생의 소비행위를 한 눈에 파악하여 교육적으로 피드백하기가 쉽지 않다. 가정에서는 학생들의 소비행위에 대한 의사소통의 길이 부족하다. 이에 본 연구는 소비의사결정 5단계와 Decision-Tree의 교육적인 면을 고려하여 합리적 소비 의사결정을 위한 6단계(문제정의, 정보탐색, 대안평가, 가치확립, 구매경험, 구매평가)를 새롭게 제안하고, 소비교실, 용돈 의사결정, 설문모듈을 통해 6단계를 체험하는 시스템을 설계하였다. 제안한 모델은 교사와 학생, 학부모 모두가 참여하여 학생의 계획적이고 합리적인 소비 의사결정 능력을 신장시키는데 도움을 줄 것이다.

This research is to develop ethical clothes consumption education program that adopts PBL which is student centered professor-learning method where the learner actively participates in lessons to recognize problems and solve them. This research also tried to see the changes in the students' ethical clothes consumption awareness and problem solving skills and self-directed learning ability after applying this program to lessons. With total of four study topic, seven ethical clothes consumption education programs were developed, and the actual lesson was conducted in controlled group and experiment group. Summary of this research is as followed: First, ethical clothes consumption education program was developed using PBL. Second, teenagers' ethical clothes consumption awareness increased much more than before the course. As both the control group and the experiment group were proven to have high ethical clothes consumption involvement and awareness, it was possible to confirm there is a need for systematic and continuous consumption education at school. Third, when a post test on changes in problem solving ability and self-directed learning ability after applying PBL based ethical clothes consumption education program was conducted, students' problem solving ability was enhanced and both factors, the awareness and behavior of self-directed learning, showed significant difference.

●우리나라의 석유소비는 전년대비 1.8%P 증가한 2,288천b/d로, 세계 6위를 기록함.-1994년 세계 8위에서 1995년 6위로 오른 이후, 수요정체에도 불구 8년 연속 세계 6위를 유지. 미국, 중국, 일본, 독일, 러시아연방, 한국 순임. ●세계 석유소비순위를 보면 지난 7년간 미국과 일본이 각각 1위와 2위를 차지하여 왔으나 지난해 중국이 드디어 일본을 제치고 2위를 차지함.-일본은 석유소비가 3년연속 감소한 반면 중국은 1997년 러시아연방을 제치고 3위로 올라선뒤 매년 석유소비량이 급격히 증가한데에 기인함. ●우리나라의 정제능력은 1996년 세계 7위에서 1997년 각각 이태리와 독일을 제치고 5위로 올라선뒤 6년간 5위를 유지하고 있음.-정제능력은 미국, 중국, 러시아연방, 일본, 한국순임. ●국별 정제능력 순위를 보면 과거 미국과 러시아연방이 각각 1위와 2위를 차지하여 왔으나, 중국이 석유소비 증가로 인해 정유공장 신ㆍ증설을 추진하여 러시아연방을 제치고 2위를 차지함.

In the present study, the variation of input power and efficiency improvement of a scroll compressor applying PWM method are experimentally investigated. The cooling capacity, input power and COP are measured under the cooling operation. The input power due to the change of the condenser and the coil addition in a main current part is measured to enhance the compressor efficiency. Measured results show that the input power and COP increase with increasing the tooling capacity. And the minimum input power of the compressor is observed. By the adoption of the double system, the consumption of compressor input power is reduced, compared with the existing system.

●2003년 우리나라 석유소비는 전년대비 1.0% 증가한 2,303천b/d로, 세계 7위를 기록함. 순위는 미국, 중국, 일본, 독일, 러시아연방, 인도, 한국 순임.-1995년 이후 8년 연속 세계6위를 유지하여왔으나 인도가 정부주도하에 10차 5개년 경제개발계획(2002~2007년)을 수립하고 이에 따라 매년 석유수요가 증가함에 따라 2003년 석유수요는 2,462천b/d를 기록, 한국을 제치고 6위를 차지함. ●세계 석유소비순위를 보면 미국이 20,071천d/b로 부동의 1위를 차지했고 2002년에 중국이 일본을 2만b/d의 근소한 차이로 2위를 차지하였으나 지난해에는 격차를 53만b/d로 벌리면서 2위자리를 지켰음. ●우리나라의 경제능력은 2,316천b/d로 전년보다 한 계단 아래인 6위를 기록함.-우리나라는 지난 1997년 이후 6년간 5위를 유지하여 왔으나, 인도가 정책적인 독려에 힘입어 정제능력을 증강한 결과 2,333천b/d로 한국을 제치고 5위를 차지함. ●국가별 정제능력 순위에서는 미국이 1,689만 4천d/b로 1위를 차지한 가운데 러시아가 정제능력을 확충하여 5,512천b/d를 기록, 5,487천b/d를 기록한 중국을 제치고 1년만에 다시 2위자리로 올라섰음.

This study aims to deeply analyze the information consumption behavior structure of rural residents in Changchun, China. and further improve the information consumption level of rural residents. Questionnaire survey and statistical analysis were used in this study. First, Through in-depth interview and open questionnaire collection and compilation of measurement questions. Secondly, residents in 15 rural areas around Changchun were selected for the survey, Finally, SPSS23.0 was used for exploratory factor analysis of recovered data, and Mplus7.4 was used for confirmatory factor analysis. The results show that the structure of information consumption behavior of rural residents in Changchun includes three dimensions of information demand, information literacy and payment ability, which is corresponding to the previous studies on information consumption behavior structure's demand power, purchasing power and information quality. This study has certain empirical validity.

본 연구에서는 공조용 실외기의 고효율화 및 소형화를 위해 응축기로 사용되고 있는 핀-관 열교환기를 동일한 전면면적의 PF 열교환기로 변경하여 성능변화 및 특성을 조사하였다. 이를 위해 3종의 PF 열교환기를 적용하여 공조기의 성능을 비교평가 하였다. 실험은 공기 엔탈피식 칼로리미터에서 공조기의 냉방능력과 소비전력을 측정하여 COP를 계산하였다. PF 열교환기를 적용한 경우에 핀-관 열교환기보다 냉방능력은 증가하고 소비전력은 감소하여 COP가 향상되었다. PF 열교환기의 핀 피치가 클수록 냉방능력과 COP는 감소하였다.

Recently, middle and low social class entered in the upper class for the specific reasons and joined reference group in order to present demonstration effect. This phenomenon was assumed the consumer's desire for housing estate not from the leisure class. The superiority which feels belong to reference group, that was able to purchase high price product and the competence which can afford a high price goods are effective in housing estate. The study had been researched for Veblen effect according to residence estate. The partial least squares path modeling was used for Veblen effect affected by various psychological attributes, housing patterns and demographics for analysis. As a result, the conspicuous consumption from tenants was higher than residents, the social face sensitivity affected positively for self esteem and housing pattern, therefore, it caused conspicuous consumption. Moreover, we found conspicuous consumption had been increased followed by more spacious housing and higher income.

The purpose of this study was (1) to investigate the changes in consumer competencies according to the types of shopping value, (2) to reveal the effects of shopping value on consumer competencies. The subjects of this study were 266 university students dwelling in Seoul. A questionnaire was used as the survey method. The data was analyzed by Cronbach's alpha, frequencies, percentile, mean, factor analysis, K-mean cluster analysis, t-test, ANOVA and Duncan's multiple range tests, multiple linear regressions. Computations were conducted by SPSS WIN 12.0. The study produced the following results. First, college students can be categorized into 3 shopping values by K-means Cluster analysis of 13 items: the hedonic shopper (shopping value), the utilitarian shopper (shopping value) and the balanced shopper (shopping value). Second, there were significant differences in grades, satisfaction with life and shopping value. That is, grade 3and utilitarian shopping value group had a higher level of consumer competency. Third, the variable that influenced consumer competency was the utilitarian shopping value, influencing consumer attitude and consumer skill. These results imply that consumers should be constantly educated and that there needs to be a campaign to promote utilitarian shopping value.
