본 연구는 쇼핑체험이 충동구매에 미치는 영향에 있어 소비자의 조절초점이 어떤 역할을 하는지 검토하는데 초점을 맞춘다. 즉 의류매장에서 느끼는 쇼핑체험이 소비자의 조절초점성향에 따라 충동구매에 미치는 영향에 차이가 있는지를 실증한다. 실증연구 결과를 요약하면 다음과 같다. 첫째, 의류매장의 체험요소인 감각적 체험과 감성적 체험은 통계적으로 유의한 수준에서 충동구매에 긍정적인 영향을 미치고 있는 것으로 나타난 반면, 합리적 체험은 충동구매에 부정적 영향을 미치고 있는 것으로 조사되었다. 둘째, 쇼핑체험 요소가 충동구매에 미치는 영향은 소비자의 조절초점성향에 따라 차이가 있음을 확인하였다. 감성적 체험이 충동구매에 미치는 영향은 예방초점 소비자보다는 향상초점 소비자에게서 더 크게 작용하는 것으로 나타났다. 이에 반해 합리적 체험이 충동구매에 미치는 부(-)적 영향은 향상초점 소비자보다는 예방초점 소비자집단에서 더 낮은 것으로 나타났다. 연구결과를 종합하면, 소비자의 쇼핑체험은 충동구매행동에 유의한 영향을 미치며, 이러한 영향은 소비자의 조절초점에 따라 차이가 있음이 확인되었다.

In this paper, we deal with the problem of practical observer design and the practical stabilization for a class of perturbed impulsive systems. We show that, under the classical conditions of uniform complete controllability and uniform complete observability of the nominal system without impulsive effects, it is possible to design an observer controller for a class of perturbed linear impulsive system when the origin is not an equilibrium point.

This study examined the effects of demographic variables and psychological mechanisms (self-efficacy, need for closure, and fashion innovativeness) on each of the four types of impulsive buying, including suggestion impulsive buying, stimulus impulsive buying, pure impulsive buying, and reminder impulsive buying. In addition, the study analyzed the impact these four types had on evaluations after impulsive buying (i.e., diversion in mood, regret for buying decision and a sense of financial loss, and dissatisfaction of products). Data was collected by a marketing research company from five hundreds consumers in seven different cities of South Korea who experienced impulsive buying in the off-line apparel stores within the past three months. The results of regression analyses indicated that self-efficacy and gender significantly affected suggestion impulsive buying. That is, the higher consumers' self-efficacy, the greater their suggestion impulsive buying was. In addition, women had higher Suggestion Impulsive Buying than men did. However, in case of Stimulus Impulsive Buying, gender was the only significant antecedent. That is, women had higher stimulus impulsive buying than men did. In terms of pure impulsive buying, fashion innovativeness was a significant predictor, and for the reminder impulsive buying level, fashion innovativeness and need for closure were significant predictors. Finally, pure and suggestion impulsive buying were correlated with positive consumer evaluations, while both stimulus and reminder impulsive buyings were correlated with negative consumer evaluations. Implications and future studies were discussed.

The purpose of this study is to compare the impulsive purchasing tendency of Korean and U.S. college students. In particular, the study examined the effects of self-regulated learning and self-regulated consumption on college students' impulsive buying tendency. A total of 680 valid samples were obtained from online self-reported surveys in Korea and the United States. Both self-regulated learning and self-regulated consumption (self-control and self-supervision) were higher in US college students than Korean students. Self-regulated learning did not influence impulsive purchasing tendency. However, the impulsive purchasing tendency increased as the level of self-supervision among self-regulated consumption decreased. When purchases were made in stores, impulsive purchasing tendency increased in both South Korea and the US. Therefore, it is necessary to make efforts to decrease the impulsive purchasing tendency by fostering self-regulated consumption capacity of college students through consumer education.

Underwater impulsive sound such as underwater blasting noise, piling noise and stone breaking hammer affects marine animal hearing response and organs. This study describes the characteristics of various impulsive noise from waterfront construction site and their effect on fish. Time constant, peak pressure, energy and SEL(sound exposure level) of four different underwater impulsive sounds are quantified. Auditory and non-auditory tissue damage ranges are derived by comparing their quantities to the exposure criteria for fish. Damage ranges of auditory tissue and non-auditory tissue of underwater boring blast of 150 kg of charge, are about 100 m and 300 m, respectively. Other three impulsive sounds also gives damage effects but less than that of underwater boring blast.

We investigate a periodically forced Lotka-Volterra type predator-prey system with impulsive perturbations - seasonal effects on the prey, periodic releasing of natural enemies(predator) and spraying pesticide at the same fixed times. We show that the solutions of the system are bounded using the comparison theorems and find conditions for the stability of a stable prey-free solution and for the permanence of the system.

Purpose: The study was done to influence of family function and degree of depression on impulsive behavior in adolescents. Method: Using convenience sampling 780 adolescents were recruited from October 29 and November 9, 2011. Data were collected using self-report questionnaires which included items on general characteristics, family function, depression, and impulsive behavior. Data were analyzed using t-test, ANOVA, Scheffe test, Pearson Correlation Coefficient, and hierarchical regression analysis. Results: The major findings of this study were as follow; 1) There was a significant negative relationship between family function and impulsive behavior (r=-.236, p<.001) and a positive relationship between depression and impulsive behavior (r=.342, p<.001). 2) Factors with a significant negative association with impulsive behavior were higher school records (${\beta}$=-.112, p<.001) and family function: positive resolution of family problems (${\beta}$=-.213, p=.008), while a significant positive association was found for unsatisfactory school life (${\beta}$=.103, p=.016), family function: emotional reactivity (${\beta}$=.159, p=.028), and depression (${\beta}$=.301, p<.001). These variables explained 20.1% of variance for impulsive behavior. Conclusion: The results of this study identify a relationship between family function, depression, and impulsive behavior in adolescents indicating variables to be addressed to reduce impulsive behavior. These variables can be used in developing intervention programs.

본 연구에서는 자아개념이 충동구매와 구매 후 감정반응에 어떤 영향을 미치는지 알아보고자 하였다. 이를 위해서 자아개념의 사회의존성-독립성에 따라 2개의 집단으로 나누어 충동구매와 구매 후 감정에 미치는 영향을 분석하였다. 충동구매는 계획성 정도에 따라 충동구매 집단과 비충동구매 집단으로 나누어 구매 후 감정을 비교하였다. 또한 심사숙고성-즉흥성 정도를 이용하여 자아개념과 구매 후 감정과의 관계를 재 검정하였다. 연구결과를 보면, 충동구매집단은 죄책감, 후회, 행복감에서 비충동구매 집단보다 높았고 자긍심에서는 비충동구매 집단이 높았다. 자아개념은 충동구매에 유의적 영향을 미쳤으며, 죄책감, 후회, 행복감에서 충동구매의 구매 후 감정에 미치는 영향을 조절하였다. 그러나 자긍심에 대해서는 조절효과가 나타나지 않았다. 이런 결과는 사회적으로 독립적인 자아개념을 가진 소비자들이 충동구매 후에 높은 부정적 감정(죄책감, 후회)과 함께 긍정적 감정(행복감)을 갖지만, 충동구매자체에 대해서는 바람직한 구매전략으로 보지 않고 있음을(낮은 자긍심) 나타낸다고 할 수 있다.

Distribution of online media sharply accelerated in the modern society, leading to robust increase in the time where individuals spend their leisure time on the Internet. One of the most popular entertainments among this is the video game industry, which gradually came to possess the characteristics like violence, cruelty, gambling, and sexuality, in order to gain attention. This study aims to investigate the addiction characteristics of users of domestic online games and to verify the causal relationship of these factors on the factors that affect impulsive crimes through Self-control. For practical verification of this study, survey was conducted for students of W High School in Incheon. This study is meaningful in that it prepared a theoretical foundation in the process of inferring criminal intent for impulsive crimes based on the effects of online games on impulsiveness, aggression, and addiction. It is also significant in that it presented a new mechanism that ego control, which occurred in the process of presenting a new variable of negative effect of online game on the criminal intent of impulsive crime, affects impulsive crime.
