A principal components analysis (PCA) of the median head-related impulse responses (HRIRs) in the CIPIC HRTF database reveals that the individual HRIRs can be adequately reconstructed by a linear combination of 12 orthonormal basis functions. These basis functions can be used generally to model arbitrary HRIRs, which are not included in the process to obtain the basis functions. To clarify whether these basis functions can be used to model other set of arbitrary HRIRs, an numerical error analysis for modeling and a series of subjective listening tests were carried out using the measured and modeled HRIRs. The results showed that the set of individual HRIRs, which were measured in our lab using different measurement conditions, techniques, and source positions, can be well modeled with reasonable accuracy. Furthermore, all subjects reported not only the accurate vertical perception but also the front-back discrimination with the modeled HRIRs based on 12 basis functions. However, as less basis functions were used for HRIR modeling, the modeling accuracy and localization performance deteriorated.

This study attempts to explain the unique patterns in Korean consumer behavior regarding the luxury fashion brands' donation activities by exploring the moderating effects of corporate ability (CA) and subjective norm (SN) on the relationship between donations and consumers' brand preference, brand trust, and purchase intention. A total of 209 completed questionnaires, collected from online surveys, were analyzed using moderated multiple regression. The result shows that donation amount information positively influences consumers' brand preference, brand trust and purchase intention toward luxury fashion brands. Next, CA strengthens the relationships between donation amount information and consumers' brand trust and purchase intention. SN from the opposite gender compensates for the negative effect of negative donation amount information on consumers' trust toward luxury fashion brands, whereas SN from the same gender does not influence those relationships. This study provides a deeper understanding of luxury fashion brands' donations and consumer responses in South Korea-one of the important test markets for luxury fashion brands to expand their business to Asian countries.

Using the extended technology acceptance model (TAM), the study aimed to understand consumers' adoption process for smart fashion products. The research model was designed to examine the impacts of perceived ease of use and usefulness on attitude and behavior intention toward smart fashion products based on the technology innovativeness, enjoyment, and subjective norm variables. An online survey was conducted on consumers by employing a marketing research company. A total of 230 useable responses were obtained. Confirmatory Factor Analysis (CFA) was performed to test the measurement model. The proposed hypotheses were tested by employing the Structural Equation Model (SEM). The results found a positive impact of perceived ease of use on usefulness and a positive influence of usefulness on attitude and behavior intention. Attitude had a positive effect on behavior intention. In addition, technology innovativeness was found to have a positive influence on perceived ease of use and enjoyment had a positive influence on usefulness and attitude. Subjective norm predicted behavior intention. The findings of the study contribute to smart fashion literature and have important implications for smart fashion product developers and marketers, as they offer insights into the important role of technology innovativeness, enjoyment, and subjective norms perceived by consumers in improving attitudes and behavior intentions toward the products. Limitations and future research directions are discussed.

Persimmon juice dye-printed fabrics with printing were used for a Galot one-piece dress. The Galot dress was assessed in comparison to a white undyed one-piece dress of the same design through a wearing test conducted in a climatic chamber with an air temperature of $30{\pm}1^{\circ}C$, $50{\pm}5%$ R.H, and 0.2m/sec air movement on 4 healthy female subjects in their 20s. The subjects went through a 30-min stable period, a 30-min exercise of walking on a $5^{\circ}$ slope treadmill at 70m/min period, and a 20-min recovery period. In addition, a physiological reaction and subjective sensation were estimated. The results showed that significant differences were mostly observed from a sweating period that occurred during the latter half of the exercise. More specific results are as follows. First, skin temperature on the chest and mean skin temperature were significantly higher (p<.01) in rayon dyed sample dresses. Second, micro-humidity on the back showed a significant difference (p<.01). Both cotton and rayon persimmon juice dyed sample dresses produced lower microhumidity than their counterparts and as for cotton the difference occurred over the entire experimental period; however, it occurred after the middle of the exercise period for rayon. Third, the sweating rate on the back decreased in both cotton and rayon with persimmon juice dye but no significant difference was observed. Fourth, subjective three sensations revealed significant differences between cotton and rayon (p<.01), indicating that the subjects felt more cool, dryer and more comfortable in a cotton Galot. As described above, the analysis of physiological responses and the subjective sensation of undyed and dyed clothing shows the effect of persimmon juice dyeing. Persimmon juice dyeing also seemly increased air permeability, moisture regain and permeability facilitating body heat ventilation, as micro-humidity and sweat rate were lowered. However, this was not shown consistently in subjective responses on comfort especially when wearing rayon dresses.

The present study was designed to investigate whether there is a consistint changes in the signals from the central and autonomic nervous systim due to olfactory stimulation. The olfactory stimuli were 0.6% orange and 2.5% valeric acid and the stimuli through the olfactory stimulator soth controlled consistint flow, controlled concentration, and saturated with vapour to prevent drying the nasal mucosa. A room air blunk served as the control stimulus, EEG was recorede from 4channels according to the international 10-20 systim. Additionally, ECG, EOG, heart rate, skin conductance and resputation were recorded comtinuously. The fast Fourier transform analysis of EEG waves was analysed with the power spectra. Averaged power spectra were computed for the following frequency bands ; delta(0-4.5Hz), theta (4.5-7Hz), alphal(7-9.5Hz), alpha2 (9.5-12.5Hz) and beta(12.5-30Hz). Withthe results of the subjective sensibility test for the ordor, the orange was related to pleasant and familiar and the valeric acid was realted to snpleasant and bothersome. There is the difference between orange and valeric acid in alphal at PG2-A2 channel. While the unpleasant stimuli seem to be increased in alphal, alpha2 and beta waves at all channels. Also, the heart rate, galvaric skin resistance seem to be decreased by pleasant stimuli and thd unpleasant stimuli shdwed the opposite. In respiration, respiration rate had been declinig tendency, and input/output ampoitued and duration showed an upward trend by olfactory stimulation with orange, while opposite by valeric acid. In conclusion, the consistent EEG changes and the autonomic responses suggests the possibilities of the subjective signal of human sensibility.

This paper explores antecedents of entrepreneurial and job search intentions based on the theory of planned behavior. Additionally, it examines the impact of entrepreneurship and job search education on these antecedents of entrepreneurial and job search intentions. The research model has been validated by analyzing 1,432 responses from undergraduate students in South Korea. The results of analysis provide several findings: First, entrepreneurship attitude, entrepreneurship subjective norm, and entrepreneurship self efficacy showed significant positive effects on entrepreneurial intention, but their effects on job search intention were insignificant. Second, while job search attitude showed significant positive effects on both intentions, job search subjective norm showed a significant effect only on job search intention, and job search self efficacy showed a significant effect only on entrepreneurial intention. Third, entrepreneurship education increased all the antecedents of entrepreneurial intention, and reduced job search attitude. These results imply that entrepreneurship and job search education should be managed comprehensively, considering their cross-effects on the antecedents of entrepreneurial and job search intentions.

The footwear such as socks and shoes is the clothing which are necessary to our life. In this study, clothing comfort of the footwear was carried out by physiological responses and subjective evaluation. As a result, the effect to walking comfort by the height of a heel in female shoes became clear. Then suitability evaluation system of shoes was proposed from the measuring results. On the other hands, the clothing comfort of the hosiery was evaluated from ECG analysis. By this analysis, it became clear that the factor which influences the clothing comfort of the hosiery was the clothes pressure in the hosiery. In the future, plane shape of the foot and solid shape must be considered in order to design the hosiery.
