The purpose of this study is to investigate the effect of the degree of mimetic purchase on product satisfaction. In addition the present study aims to investigate the moderating role of the self esteem and public self in the relationship between mimetic purchase and product satisfaction. Taken together, hypothesis 1 is as in the following. H1 : As the degree of mimetic purchase increases, product satisfaction will increase. To reveal the moderating role of the self esteem and public self in this path, 2 research hypotheses are derived as follows: H2 : The effect of mimetic purchase on product satisfaction is moderated by self esteem. H3 : The effect of mimetic purchase on product satisfaction is moderated by public self. Results from an empirical study showed that as the degree of mimetic purchase increases, product satisfaction increase. Thus, H1 is fully supported. And the results showed that the first interaction effect(H2) between the mimetic purchase and the self esteem is significant. Thus, H2 is also supported. But the second interaction effect(H3) has been shown to be not significant.

본 연구에서는 가상시장에서 인터넷쇼핑몰을 통해 제품을 구매한 경험이 있는 소비자의 재구매의도를 확인하고자 시도하였다. 인터넷쇼핑몰을 통해 제품을 재구매하기 위해서는 이전 구매경험의 만족이 결정적 요인으로 작용할 것으로 가정하였다. 이러한 쇼핑만족에 영향을 주는 요인으로는 쇼핑몰의 구조적 특성(심미성, 이용편리성), 제품특성(품질, 가격), 그리고 서비스 특성(확신성, 신뢰성, 반응성) 등을 포함하였다. 이들 요인이 쇼핑만족에 영향을 주고, 만족이 재구매의도에 영향을 줄 것으로 가정하였다. 또한, 이들 만족과 재구매의도간의 관계는 지각된 위험 및 제품관여에 따라 조절역할을 할 것으로 가정하였다. 이러한 가설들간의 관계를 분석하고자 구조방정식모델을 실시하였고, 조절변인들의 조절효과는 조절회귀분석을 통해 검증하였다. 분석결과, 모든 연구가설들은 유의적으로 나타났다. 즉 쇼핑몰의 구조적 특성, 제품특성 및 서비스 특성은 쇼핑만족에 영향을 주며, 이러한 쇼핑만족은 소비자의 재구매의도에 영향을 주는 것으로 나타났다. 또한 만족과 재구매의도간의 관계는 지각된 위험과 관여수준에 따라 조절역할을 하는 것으로 나타났다

This paper describes a recursive least-squares based convergent algorithm for driving characteristic classification for personalized autonomous driving. Recently, various researches on autonomous driving technology have been conducted for level 4 fully autonomous driving. In order for commercialization of the autonomous vehicle, personalized autonomous driving is required to minimize passenger's insecureness to the autonomous vehicle. To address this problem. this study proposes mathematical model that represents driving characteristics and recursive least-squares based algorithm that can estimate the defined characteristics. The actual data of two drivers has been used to derive driving characteristics and the hypothesis testing method has been used to classify two drivers. It is shown that the proposed algorithms can derive driving characteristics and classify two drivers reasonably.

This study examined the role and relationship among cognitive response(attractiveness, familiarity, actual self-congruence, ideal self-congruence and sympathy) factors, emotional response(empathy, flow, affection) factors, identification mediating between cognitive and emotional response, and interactivity. Hypotheses based on literature reviews were analyzed and according to the results, all of hypotheses except two hypotheses were supported. Firstly, the results revealed that except characteristic attractiveness and actual self-congruence, story attractiveness, characteristic familiarity, story familiarity, and ideal self-congruence influenced on sympathy positively. Secondly, this study examined the role and relationship between identification mediating between cognitive and emotional response and interactivity. As a result, identification and interactivity mediated with sympathy and empathy had positive effects. Finally, in respect of emotional responses empathy, flow, and affection had positive effects.

The purpose of this study is to identify the influencing factors of married men's household labor time by generation to understand the changes in male participation in household labor. To this end, married men were classified into Baby Boomers, Generation X, and Generation Y, and the factors of participation in household labor for each generation were analyzed by applying the hypothesis of participation in household labor. As for the data, the original data of the National Statistical Office's "2019 Time Use Survey" were used. Multinomial logistic analysis was conducted to analyze the factors affecting married men's household labor time. As a result of the analysis, household labor time for Baby Boomers can be explained by the hypothesis of economic efficiency, gender role attitude, and the demand/response capability, while household labor time for Generation X can be explained by economic efficiency hypothesis, gender role attitude hypothesis, time-availability hypothesis, and demand/response capability hypothesis. It was found that the household labor time for Generation Y can be explained by the time-availability hypothesis and demand/response capability hypothesis. The fact that each generation has different factors of participation in household labor suggests that the characteristics of each generation should be considered in establishing policies to support the work and family balance for men.

본 연구에서는 증권사 정보시스템의 아웃소싱 성과에 영향을 미치는 기업특성적 변인에 대해 파악하고자, 아웃소싱 수혜기업인 증권사의 조직 및 부문적 특성이 아웃소싱 정도의 매개효과를 통해 아웃소싱 성과(업무효용성, 업무능률성, 업무생산성, 예산감소율)에 어떠한 영향을 미치는지 실증적으로 검증하였다. 증권사의 조직적 특성(경쟁전략, 재무능력)이 아웃소싱 정도를 매개로 성과에 미치는 영향을 검증한 가설 1과 증권사의 부문적 특성(업무특수성, IT 자원, IT 역량)이 아웃소싱 정도를 매개로 성과에 미치는 영향을 검증한 가설 2를 실증분석한 결과, 경쟁전략, 재무능력, 업무특수성, IT 자원, IT 역량의 요인들이 아웃소싱 정도를 통해 업무효용성과 예산감소율에 영향을 주는 것을 확인할 수 있었다. 특히 재무능력, IT 역량 등이 업무효용성, 예산감소율과 같은 정보시스템 아웃소싱의 성과에 상대적으로 많은 영향력을 미치는 것으로 나타났으며, 정보시스템 아웃소싱 정도의 매개효과를 확인할 수 있었다.

The aim of this study was to analyze the aerodynamic properties of the composite cable-stayed bridge by conducting three-dimensional wind tunnel tests. Focusing on the improved section of the bridge in the two-dimensional wind tunnel tests, the bridge's aerodynamic stability was estimated based on the angles of attack and the wind angles. The aerodynamic properties of vertical galloping, torsion galloping,and torsion flutter were also estimated based on the design wind velocity, and because much of the cable-stayed bridge was constructed using FCM, it was not sufficiently stiff during the bridge's construction. Therefore,the experience progressed by stages: from the full stage to the tow stage, and until the bridge became a single tower. Since the original plane was designed to be a steel box girder, the aerodynamic properties of the steel-box-type and composite-type girder could be compared. The results of this study can be utilized as basic data regarding the aerodynamic properties of medium-length and short composite cable-stayed bridges.

This study analyzed causal relationship between electricity consumption and economic output (GDP) for Korea from 2001 to 2014 employing the vector error-correction model estimation by manufacturing sector. The results of unit-roots tests show that all sectoral GDP and electricity consumptions were not stationary. And cointegration tests show that processed foods, Wood Pulp Paper, electricity apparatus, Precision Medical sectors had a linear combinations in the long run between electricity consumptions and economic growth. With respect to the direction of causality, manufacturing sector has a uni-directional running from economic output (GDP) to electricity consumption in short term. The results of study show that sectoral causal relation were different each other in short term and long term. These findings imply that electricity demand management policy focusing on efficiency improvement is necessary to minimize negative impacts on economic growth and to adopt suitable structural policies can induce energy conservation.

가공송전선의 수명은 가설 후 경과된 기간(약 36년)으로 정하는 것이 일반적이나 가설된 지역의 환경적 요인이나 전선의 재질상의 특성, 전력공급량 등에 의하여 열화상태가 다양하게 진행된다. 따라서 현재와 같이 모든 전선에 대하여 일정기간으로 정해진 교체 시기는 현실적이지 못하다. 실제로 전선의 단선사고는 경년과 같은 전선의 이력보다는 부식 환경에 노출된 전선의 취약성으로 인하여 초래되는 경우가 많다. 정확한 전선의 수명을 진단하기 위해서는 가공송전선이 노출되어 있는 환경 하에서 경년에 따른 기계적, 전기적 특성의 변화를 조사하여 복합적 인자들을 정량적으로 처리하는 것이 필수적이다.
