Consumers often act impulsively when making internet purchases. Triggered by easy access to products, lack of social pressure, and absence of delivery impediments, impulse buying frequently occurs in the context of internet shopping. This study tests the structural equation model of the impulse buying process for fashion products when internet shopping and examines impulse buying process differences between Korean and Chinese consumers. A total of 985 usable questionnaires were obtained from college students. Data were analyzed by structural equation model analysis using a correlation matrix with a maximum likelihood by AMOS 21.0. Results showed that increased internet browsing by consumers resulted in more impulse buying as mediated by the urge to buy; in addition, more impulse buying by consumers resulted in a higher consumer satisfaction experience. Pure impulse buying created more important antecedents of satisfaction than the promotion-oriented impulse buying. Impulse buying showed a high similarity between Korean and Chinese consumers; however, increased influence from promotion activities resulted in more fashion product impulse buying for Chinese consumers versus Korean consumers. We confirm that one of the outcomes of the impulse buying process is impulse buying product satisfaction. Korean and Chinese consumers also present similarities and differences in fashion product impulse buying. A managerial implication is discussed for retailers of fashion products to develop strategies to increase consumer browsing and subsequently trigger impulse buying accompanied with consumer satisfaction.

This study tested how the mobile impulse buying(m-impulse buying) of fashion products was related to shopping motives and mobile applications(apps) browsing in the context of mobile shopping. A total of 316 self-administered questionnaires were obtained from college students who had experienced m-impulse buying of fashion products during the most recent six months. A structural equation model using a correlation matrix with maximum likelihood was estimated for examining the relationships among shopping motives(e.g., hedonic shopping motive and utilitarian shopping motive), apps browsing, and m-impulse buying of fashion products(e.g., fashion-oriented impulse buying and pure impulse buying) by AMOS 21.0. Findings showed that hedonic shopping motive and utilitarian shopping motive had significant effects on apps browsing in their mobile shopping. Apps browsing had a significant effect on fashion-oriented impulse buying, but did not significantly effect on pure impulse buying of fashion products. Additionally, the hedonic shopping motive had directly significant effects on both fashion-oriented impulse buying and pure impulse buying, whereas the utilitarian shopping motive significantly effected on only the pure impulse buying of fashion products in their shopping. This study suggests that the hedonic shopping motive played an important role to determine the m-impulse buying of fashion products and the utilitarian shopping motive played a role in activating apps browsing relevant to mobile shopping for fashion products. Managerial implications are discussed for retailers related to the fashion products in mobile shopping.

The purpose of this study was to explore the effects of adolescent attachment to mothers and peers, self-esteem and impulse control on delinquency. The subjects were 624 eighth and eleventh grade students in Busan. The subjects rated themselves on questionnaires regarding attachment to mothers and peers, self-esteem, impulse control and latent delinquency. The major findings of this study were as follows; 1) Male adolescent delinquency increased with grade. But no grade difference was found in female adolescent delinquency. And male adolescent had more delinquency than female adolescent. 2) Grade had a direct and indirect effect through attachment to peers and impulse control on male adolescent delinquency and was the first positive contribution factor. Impulse control had a direct negative effect on male adolescent delinquency. Attachment to mothers had an indirect negative effect through self-esteem on male adolescent delinquency. Attachment to peers had an indirect negative effect through self-esteem and impulse control on male adolescent delinquency. Self-esteem had an indirect negative effect through impulse control on male adolescent delinquency. 3) Attachment to mothers had a direct and indirect effort through impulse control on female adolescent delinquency and was a first negative contribution factor. Impulse control had a direct negative effect on female adolescent delinquency. Attachment to peers had an indirect negative effect through impulse control on female adolescent delinquency. Grade had an indirect negative effect through impulse control on female adolescent delinquency. Self-esteem had no effect on female adolescent delinquency.

The college students selected by random sampling were classified into four groups by their body cathexis and clothing attitude to investigate differences in the consumer's Impulse-Buying in a negative consumer situation. Consumer cluster were classified into four groups: positive congruity(G1), positive incongruity(G2), negative congruity(G3), negative incongruity(G4). The result are as follows: G1 had high impulse. After Impulse-buying in a negative consumer situation they had negative attitude. G2 tends to do Impulse-buying a lot in a negative consumer situation. G3 had low impulse. After impulse-buying in a negative consumer situation they had both positive and negative attitude. After impulse-buying, G4 had negative and they tend to do a pure impulse buying in a negative consumer situation. As a result, the buying-impulse could cause the impulse-buying.

The current study addresses experimental and computational work of impulse wave discharged from the exit of two kinds of right-angle pipe bends, which are attached to the open end of a simple shock tube. The weak normal shock wave with its magnitude of Mach number from 1.02 to 1.20 is employed to obtain the impulse wave propagating outside the exit of the pipe bends. A Schlieren optical system visualizes the impulse wave discharged from the exit of the pipe bends at an instant. The experimental data of the magnitude of the impulse wave and its propagating directivity are analyzed to characterize the impulse waves discharged from the exit of the pipe bends and compared with those discharged from a straight pipe. Computational results well predict the experimented dynamic behaviors of the impulse wave. The results obtained show that a right-angle miter bend considerably reduces the magnitude of the impulse wave and its directivity toward to the pipe axis, compared with the straight pipe and right-angle smooth bend. It is believed that the right-angle miter bend pipe can playa role of a passive control against the impulse wave.

In this paper, influences of a ultra wideband (UWB) antenna on impulse channel measurement are investigated in time domain (TD) and frequency domain (FD) as well. Firstly, impulse response of an UWB antenna is obtained and then using the result of impulse response of the UWB antenna, influences of the antenna on impulse radio channel is analyzed. Furthermore, using the impulse response of the UWB anenna, method of impulse radio channel analysis is presented by excluding the effect of the antenna from an impulse radio channel. For verifying the theory, a modified conical monopole antenna is designed for measuring impulse radio channel and its impulse response is obtained. After that, in order to investigate the effects of the UWB antenna on an impulse radio channel, multipath environments are set up in an anechonic chamber and transmission coefficient for each multipath environment is measured with an aid of vector network analyzer. Data measured in frequency domain is transformed into those in time domain by way of signal processing. Measurement shows that such properties of the antenna as dispersion and ringing affect impulse radio channel. Moreover, using the impulse response of the antenna, impulse response of only multipath channel is obtained.

This study analyzed rainfall-runoff characteristics by deriving multiple impulse responses. The concept of competing impulse responses was used for deriving multiple impulse responses. Based on this concept, each response function derived competes to be selected for simulating the runoff measured. This concept of competing linear impulse responses was applied to four basins, Jeongseon, Yeongwol, Youngchoon and Chungju Dam. One to three impulse responses have been derived and compared each other considering basin characteristics. First, in case of deriving one linear impulse response, the peak flow of the impulse response was found to be increased according to their study basins area. In case of deriving two linear impulse response, the peak flow of the first impulse response and the duration of the second impulse response were increased according to their basin size. The case of deriving three impulse response showed similar characteristics of deriving two impulse responses. However, the peak flow of third impulse response was very small and lasted quite long time. Summarizing these results considering the basin characteristics, the first impulse response seems to be related with the surface runoff, the second impulse with the surface runoff and interflow, and the third impulse response with the interflow and base flow.

This paper presents the characteristics of transient and effective impulse impedances for deeply driven grounding electrodes used in soil with high resistivity or in downtown areas. The laboratory test associated with the time domain performance of grounding piles subjected to a lightning stroke current has been carried out using an actual-sized model grounding system. The ground impedances of the deeply driven ground rods and grounding pile under impulse currents showed inductive characteristics, and the effective impulse ground impedance owing to the inductive component is higher than the power frequency ground impedance. Both power frequency ground impedance and effective impulse ground impedance decrease upon increasing the length of the model grounding electrodes. Furthermore, the effective impulse ground impedances of the deeply driven grounding electrodes are significantly amplified in impulse currents with a rapid rise time. The reduction of the power frequency ground impedance is decisive to improve the impulse impedance characteristics of grounding systems.

Multiple-lightning impulse currents are a general feature of the lightning ground f=flash. It is therefore necessary for lightning arresters used in power systems to be estimated by applying not only a single-lightning impulse current but also a multiple-lightning impulse currents. This paper presents the effects of multiple-lightning impulse currents on deterioration of ZnO arrester blocks. The multiple-lightning impulse generator which can produce quadruple 8/20$[\mus]$ 5[kA] with separation time of 30~120[ms] is designed and fabricated. The total energy applied to the arrester block at each impulse is about 1,200[J]. In experiment, various parameters such as leakage current component, reference voltage, and temperature are measured with the number of applied impulse current. Also, micro-structure changes of the ZnO blocks after applying the single and the multiple-lightning impulse currents of 200 times are compared. The experimental results indicate that the types of arrester blocks are more vulnerable to deterioration or damage by multiple-lightning impulse currents.
