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 purposes of this study were to find out the catalogue and online-order apparel shoppers' impulsive purchase orientation and impulsive purchase stimuli. Self-administered questionnaires were distributed to women over than 20 years, and collected from middle to the end of November in 2000. Frequencies, percentages, and mean were calculated. One-way ANOVA, chi-square test, factor analysis, and cluster analysis were used, and Duncan's Multiple Range test was followed. 1. Factors of impulsive purchase orientation were relax from negative moods, design property, inducement from neighbors, taste congruence, price property of apparel, positive moods, and loose-control, and were segmented into the low impulsive purchaser, the reasonable purchaser, the fulfilled with positive moods, and the high impulsive purchaser. The factors of impulsive purchase stimuli were apparel property, consumer service, sales promotion on the point of sales, and low price. 2. The low impulsive Purchaser was affected little by impulsive purchase stimuli, spent a little money on apparel, and the married with high education level were the most. The reasonable purchaser was affected by sales promotion on the point of sales or low price, spent a little money on apparel, and students or house-wives were the most The fulfilled with positive moods was affected by low price, and students or career women with high education level were the most, but spent less money on apparel. The high impulsive purchaser was affected by various impulsive purchase stimuli, the young unmarried with high education level were the most, and spent more money on apparel. 3. The younger, the unmarried, students or career women, and shoppers with higher income or apparel expenditure showed a higher impulsive purchase tendency for relax from negative mood, design property, for inducement from neighbor, taste congruence, and positive moods. 4. The older, the married, house wives, and shoppers with higher apparel expenditure were stimulated by apparel property or consumer services.

Impulsive vibration velocity is monitored at the surface and the boundary surface of rocks as various impulsive forces of horizontal and vertical directions were given to rocks which had difference in uniaxial compressive strength for investigate to the vibration velocity of rocks according to the impulsive direction and the monitoring site. The vibration velocity of the boundary surface of rocks was about 2.9 times or much larger than that of the surface at the same scaled distance in the case of horizontal impulsive forces, and was above 4.2 times in the case of vertical impulsive forces. The attenuation exponents of the vibration velocity equations in the surface and the boundary surface of rocks make a vast difference with the impulsive directions, but is makes little difference in the case of the same impulsive direction. The ratio of vibration constants of the surface to the boundary surface of rocks is that square and cube root scaled equation is a range of 2.7∼3.0 and 4.9∼5.0 respectively in the case of horizontal impulsive forces, and is a range of 4.2∼5.7 and 7.7∼11.5 respectively in the case of vertical impulsive forces.

This study explored the level and general propensity of consumption-oriented attitude and impulsive buying behavior of high school students, and clarified factors affecting impulsive buying. The research results can be summarized as follows. 1. The degree of consumption-oriented attitude and impulsive buying behavior of high school students were relatively low. 2. Consumption-oriented attitude was found to have significant differences among students based on monthly allowance, self-esteem, influence of friends, influence of mass media and influence of consumer education at school. Moreover, impulsive buying behavior was found to have significant differences according to sex, level of parents's education, fathers job, monthly household income, monthly allowance, influence of home, influence of friends and influence of mass media. 3. The impulsive buying differed significantly according to consumption-oriented attitude. That is, the group showing a higher degree of consumption-oriented attitude also indicated higher impulsive buying. 4. The variables affecting the level of impulsive buying behavior were the level of consumption-oriented attitude, influence of mass media, influence of friends and sex. In other words, consumption-oriented attitude, influence of mass media and influence of friends had a positive affect, and female students were more apt to impulsive buying than male students.

The current study depicts and experimental work of the impulsive wave discharged from the exit of several kinds of right-angle bend pipes, which are attached to the open end of a simple shock tube. The weak normal shock wave with Mach number from 1.02 to 1.20 is employed to obtain the impulsive wave propagating outside the exit of the pipe bends. The experimental data of the magnitude of the impulsive wave and its propagation directivity are analyzed to characterize the impulsive waves discharged from the right-angle bend pipes and compared with those from a straight pipe. The impulsive waves are visualized by a Schlieren optical system. A computation work using the two-dimensional, unsteady, compressible Euler equation is also carried out to represent the experimented impulsive waves. The results obtained show that a right-angle miter bend considerably reduces the magnitude of the impulsive wave and its directivity toward to the pipe axis, compared with the straight pipe. It is believed that the right angle miter bend pipe can play a role of passive control agianst the impulsive wave.

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.

Impulsive sound and vibration signals in gear are often associated with their faults. Thus these impulsive sound and vibration signals can be used as indicators in the diagnosis of gear fault. The early detection of impulsive signal due to gear fault prevents from complete failure in gear. However it is often difficult to make objective measurement of impulsive signals because of background noise signals. In order to ease the detection of impulsive signals embedded in background noise, we enhance the impulsive signals using adaptive signal processing.

In this paper we develop useful relations which estimate the difference between the solutions of nonlinear impulsive differential systems with different initial values. Then we obtain the converse h-stability theorem of Massera's type for the nonlinear impulsive systems by employing the $t_{\infty}$-similarity of the associated impulsive variational systems and relations.
