In order to identify the antecedents of internet purchasing intention toward fashion items, this study examines shopping-related variables as both direct antecedents of internet purchasing intention, and as indirect antecedents of internet purchasing intention through online-related variables. Impulse buying and market mavenism were considered as shopping-related variables, whilst online interaction readiness and online consumer procrastination were considered as online-related variables. It was hypothesized that impulse buying and market mavenism not only directly influence purchasing intention toward fashion items, but also indirectly influence it through online interaction readiness and online consumer procrastination. Data were gathered by surveying university students in Seoul using convenience sampling. A total of 286 questionnaires were used in the statistical analysis. SPSS was used for exploratory factor analysis, and AMOS was used for confirmatory factor analysis and path analysis. The factor analysis of market mavenism, impulse buying, and online consumer procrastination revealed one dimension, whilst the factor analysis of online interaction readiness revealed two dimensions: 'online relationship' and 'internet role.' Tests of the hypothesized path proved that impulse buying indirectly influences internet shopping intention only through online consumer procrastination, whereas market mavenism influences internet shopping intention indirectly through both online interaction readiness and online consumer procrastination. The results will be useful for Internet shopping mall marketers and for future study.

In this study, determination method of initial optimal nozzle expansion in pintle rocket was investigated. The initial optimal initial nozzle expansion was decided by maximizing the mass-averaged thrust coefficient that is calculated from thrust coefficient of minimum and maximum chamber pressure. The determination of initial optimal initial nozzle expansion was equivalent to that of the minimum propellant mass which was required for obtaining the desired mission performance. The highest pressure, thrust turndown ratio and total impulse ratio effected on the initial optimal nozzle expansion. Among them, total impulse ratio had great influence on the initial optimal nozzle expansion.

We analyzed the impulse on 24 sensors location under the foot using the Parotec system for the investigation of the relationship between the shoe type and the foot pathologies. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with the impulse distribution of the sport shoe, greater impulses were shown at the 1$^{st}$ phalange and the 1$^{st}$ metatarsal-phalangeal head in high-heel shoes, lateral tarsal bone and medial metatarsal bone in platform shoe, medial tarsal bone in inline-skate, and medial tarsal bone and 1st phalange in heelys shoe. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.ies.

This study tested how impulse buying behavior for apparel was related to hedonic consumption and impulse buying tendencies and emotion in the context of shopping. A total of 290 self-administered questionnaires were obtained from college students during scheduled classes. A structural equation model using a correlation matrix with maximum likelihood was estimated for examining the relationships among consumer tendencies of hedonic consumption and impulse buying, positive emotion, and impulse buying behaviors by LISREL 8.53. Findings showed that impulse buying behaviors for apparel could be classified into planned, reminded, and fashion-oriented impulse buying typologies. Hedonic consumption and impulse buying tendencies had significant effects on positive emotion. Positive emotion had a significant effect on planned, reminded, and fashion-oriented impulse buying for apparel. This study suggests that positive emotion plays an important role in determining impulse buying behaviors relevant to hedonic and impulse buying tendencies. Managerial implications for apparel retailers are discussed.

In this paper, experimental investigation results of the effect of partial admission ratio on the performance of axial turbine was presented. A supersonic impulse turbine of gas generator cycle liquid rocket engine turbopump was used for the test. for experimental purpose, a nozzle block, in which total 14 number of axi-symmetric convergent-divergent nozzles are arranged circumferentially, was designed and manufactured. Partial admission ratio was controlled by changing the number of active nozzles. High pressure air was used as working medium for the test. The experimental result revealed that the performance of the supersonic impulse turbine does not much affected by the partial admission ratio for supersonic impulse turbine.

This study investigates differences in fashion products attributes, mobile shopping mall attributes, impulse buying behavior, and satisfaction according to mobile shoppingconsumption value. The findings provide new information on marketing strategy for mobile shopping malls. A total of 283 usable questionnaires were obtained from college students. Data were analyzed by frequency analysis, factor analysis, and ANOVA using SPSS 21.0 for Windows. The results were as follows. First, according to the consumption value, consumer were classified into 3 groups: social/functional oriented, indifference and epistemic/emotional oriented. Second, the conspicuous-functional pursuit group considered utility and exhibition more important in regards to fashion products attributes for the consumption value group, the personality pursuit group also considered aesthetics and utility more important than other groups. Third, conspicuous-functional pursuit group considered continuous management more importantin regards to the importance ofmobile shopping mall attributes for the consumption value group, the personality pursuit group considered informationexchange more important than the other groups. Fourth, the conspicuous-functional pursuit group and Personality pursuit group considered impulse purchase behavior more important than the emotionalpursuit group. The conspicuous-functional pursuit group considered satisfaction after impulse purchase behavior more important than other groups.

Lightning impulse $(1.2/44[\mus])$ and damped oscillating impulse $(Osc./44[\mus])$ : 0.83[MHz]) breakdown characteristics in sulphur-hexafluoride/nitrogen (SF6-N2) mixtures were investigated. The predischarge currents were observed to clarify the breakdown mechanism. th experiments were carried out under nonuniform electric fields disturbed by a needle-shaped protrusion whose length and diameter are 10[mm] and 1[mm] at total gas pressure up to 0.5[MPa] with nitrogen concentrations varying from 5 to 20[%] in the mixture. The electrical breakdowns of SF6-N2 mixtures for both the positive and negative polarities develop with steplike pulses in leader mechanism and the breakdown voltage -time (V-t) characteristics were affected by the space charge. The voltage-time curves for the negative oscillating impulse voltage were extended over the longer time range. The minimum breakdown voltages for the negative lightning and oscillating impulse voltage were higher than those for the positive ones. in particular the positive breakdown voltages were independent of the gas pressure.

The purpose of this study is to investigate the effects of hypertension and diabetes mellitus on depression and suicidal impulse through the total inspection on specific rural areas in Gangwon-do. This survey selected adults over the age of 30 and conducted from May 19 to Sep. 30 in 2014. Of the 1,200 questionnaires distributed, 970 were completed and returned to be used for the study. To figure out the actual condition of hypertension and diabetes among the participants, the research examined the degree of their depression and suicidal impulse. It examined their smoking and exercise habits to check their health conditions. The research showed that patients diagnosed with hypertension and diabetes had a higher tendency of depression and suicidal impulse. The significant variable affecting depression is suicidal impulse(p<0.001>). Also, the significant variables affecting suicidal impulse are hypertension and depression. Based on these results, local health institutions need to include mental health services for the patients with hypertension and diabetes and coordinate them comprehensively and effectively.

Consumers nowadays spend more time using computers and are getting used to buying products through the Internet(Park, 2002), and therefore, understanding consumers' impulse buying behavior in an online shopping context is also important for retailers. The purpose of this study was to examine the relationship between online apparel impulse buying behavior and the two risk dimensions of apparel involvement(i.e., risk importance, risk probability). The data were collected using an online survey with a structured questionnaire. A total of 339 college students were used in the study. The results of MANOVA showed that the impulse buyer group perceived the risk importance and risk probability of apparel involvement significantly lower. Based on the results, the two hypotheses were supported. From the results of the present study, it is concluded that the two risk dimensions of apparel involvement are negatively related to online impulse buying behavior of apparel products. From the results of the present study, it is concluded that the risk dimensions of apparel involvement are closely related to the online apparel impulse buying behavior.
