Small luxury purchase as self-gifting is one of the latest consumer trends in self-gifting. Although this consumption trend continues to grow in various fields, little research has been conducted on related consumer behavior. As such, this study was conducted to empirically investigate the current consumer behavior involved in purchase of small luxury self-gifts. The objectives of this study are to determine the current status of self-gifts markets, identify motives and orientations of self-gifting, and investigate the effects of the motives on self-gifts orientations. A total of 199 respondents were used in data analyses. Regarding motives for self-gifting, four motives - self-comfort, self-reward, anxiety, and showing off - were identified; regarding self-gifting orientations, five factors - rationalization (emotional comfort, product attributes, self-defense, and conformity) and the luxury being within one's spending limit - were identified. The study determined the effects of the motives on the orientations, and the effects of the motives and the orientations on post-purchase consumer reaction. This study conducted an empirical investigation on small luxury self-gifting and moreover, the study determined the motives, orientations, and consequences of self-gifting, which have not yet been explained in the literature.

In previous researches, the self-stability was studied for the spring-mass model and the two segment leg model. In these researches, it was presented that the spring-mass model has the self-stable region at relatively high speed running and the two segment leg model has the self-stable region at relatively low speed running. If the model was run in the self-stable region, the cost of transport is zero ideally. That is, actually, only the energy loss is needed to compensate for running. This means that the energy efficiency is high, running in the self-stable region. We want to have high energy efficiency at low and high speed running. So, in this paper, we propose the design direction of the three segment leg having the self-stable region at low and high speed running. And we prove the self-stable region of the three segment leg designed by the proposed design direction.

The purpose of this study was to investigate the effect of self-efficacy and appearance interest on appearance management and clothing purchase behavior of new silver generation. The research method was a survey method using a questionnaire. The subjects were 300 new silver woman(aged from 50 to 64) living in the large city. Statistical analysis methods were factor analysis, Cronbach's ${\alpha}$ and multiple regression analysis. The results of this study were as follows. The self-efficacy factor divided into three categories including self-control efficacy, social self-efficacy and physical self-efficacy. And appearance interests were divided into four categories including weight control interest, outfit management interest, interest in clothing and disinterest in appearance. Self-efficacy had significant effect on various appearance interests. Especially physical self-efficacy was the important factor which could describe the appearance interests more effectively. Self-efficacy and appearance interests had significant effect on appearance management and clothing purchase behavior. Social self-efficacy could describe more appearance management behavior, while on the other side self-control efficacy could describe the clothing purchase behavior more effectively.

This study was to find out clothing design preferences, according to the clothing self-image of elderly women and to grasp the variety on clothing of elderly women and thereby to help in merchandise production planning and putting the brands into markets and to provide data for establishing a sales strategy a d to itemize women with the goods which can satisfy the desire and taste of consumer groups in the quality market. For this purpose , various researches as above were conducted .The object of this study was a total of 488 elderly women above full 55 from an elderly women and who lived in downtown Pusan. The data were analysed by using MANOVA, ANOVA , factors analysis and frequency analysis, and the Cronbach α was also applied . The conclusions made based on the theoretical background and the result of questionnaire surveys are as follows ; 1. The realistic self-image of clothing showed a similar pattern by age. 50's and 60's showed little difference by item but 70's was greater in variation between items compared to 60's. The response to each item was that most people answered "common" and they showed a pattern that responded low only in items of 'colorful' , individualistic', 'susceptible to fashion'. A similar pattern was shown by age band also in the ideal self-image and the response to each item appeared higher than in the realistic self-image , and also in items of 'colorful', 'individualistic ' , 'susceptible to fashion' the response appeared low and showed a unity. 2. The results of clothing design preferences examined on the self-image according to age are as follows ; 1) Fro jacket in the realistic self-image , 50's and 60's preferred 'tailed collar' , 'set-in sleeve', 'hips long' and 'plain jacket' and 70's agreed to the design preferences in the items except 'open collar' and also in the idealistic self-image , the degree of preference was same. 2) For skirt in the realistic self-image , 50's and 60's preferred 'tight skirt', 'normal length' , 'plain skirt' and it was appeared that 70's preferred 'pleat skirt' , 'medium length' , 'plain skirt'. Also in the idealistic self-image , the degree of preference was same. 3) For blouse in the realistic self-image, 50's preferred 'open collar', 'round neck line' , 'long set-in sleeve' , 'plain separation belt', 'open front', 'zipper' ad 60's agreed to the favorite designs with 50's except puff sleeve, and 70's appeared to prefer fastening buttons without belt. In the designs preferred in the idealistic self-image, 50's agreed with 50's of the realistic self-image and for 60's , the designs except puff sleeve type and no belt type agreed to 50's and 70's except puff sleeve agreed with 70's of the realistic self-image in their design preferences.

This research investigates how interest develops across a set of tasks within a course defined by a specific knowledge domain. The current study examined the relationships among self-concept, self-efficacy, Korea-related factors, and evaluation, in the context of learning about the Hanbok costume at Chinese universities. A survey (n=300) was conducted using an online survey website (www.sojump.com) from the 1st to the 25th of June. The structural equation model (SEM) analysis, including total and specific forms of self-evaluation with Hanbok courses, showed that self-concept was positively associated with self-efficacy. Conversely, K-culture interest and K-country image did not significantly affect self-efficacy in clothing, but positively affected Hanbok's self-efficacy. Meanwhile, the more self-efficacy perceived, the higher the level of evaluation. Overall, our findings imply that supporting the students' Korean culture interest, country image perception, and self-concept for regulation can enhance self-evaluation and self-realization success. Theoretical and practical implications for Hanbok courses are discussed.

Self-sensing measurement of piezo inkjet and its application are discussed. The pressure wave inside the inkjet dispenser was measured by current measurement due to self-sensing capability of PZT. The pressure wave measured from current was verified by commercially available laser vibrometer. Here, two applications using self-sensing signal were discussed: waveform design for high speed jetting and condition monitoring. For waveform design, two pulse waveform was designed based on self-sensing signal such that the pressure wave after droplet formation can be minimized. For condition monitoring, self-sensing signal was shown to be effective in detecting air bubble trapped in inkjet printhead.
