EEG-based brain-computer interfaces has focused on explicitly expressed intentions to assist physically impaired patients. For EEG-based-computer interfaces to function effectively, it should be able to understand users' implicit information. Since it is hard to gather EEG signals of human brains, we do not have enough training data which are essential for proper classification performance of implicit intention. In this paper, we improve the subject independent classification of implicit intention through the generation of additional training data. In the first stage, we perform the PCA (principal component analysis) of training data in a bid to remove redundant components in the components within the input data. After the dimension reduction by PCA, we train ICA (independent component analysis) network whose outputs are statistically independent. We can get additional training data by adding Gaussian noises to ICA outputs and projecting them to input data domain. Through simulations with EEG data provided by CNSL, KAIST, we improve the classification performance from 65.05% to 66.69% with Gamma components. The proposed sample generation method can be applied to any machine learning problem with fewer samples.

Purpose: This study was done to identify and compare factors associated with intention to receive Human Papillomavirus (HPV) vaccine between male and female undergraduate students. Methods: In the fall of 2010, 479 students responded to self-administered questionnaires about their intention to receive HPV vaccine, HPV knowledges, HPV related involvements and optimistic bias, subject's characteristics including opinion about HPV vaccine. Mann-Whitney U test, uni-variate and multi-variate logistic regression were used for data analysis with SPSS/WIN. Results: Intention to receive vaccine were 22.0% of men and 25.0% of women. There were significantly different in HPV knowledge (Z=-2.74, p=.006), optimistic bias (Z=-4.60, p<.001), vaccine is necessary for women (Z=-4,30, p<.001), vaccine is necessary for men (Z=-4.37, p<.001), vaccine is necessary if only symptom exist (Z=-4.52, p<.001), but there were not different in intention to receive vaccine, involvement between men and women. Concern about vaccine safety (OR=3.19, 95% CI 1.63~6.23) was determinant of intention to receive HPV vaccine for men. Conclusion: This study showed gender differences in HPV knowledge, HPV related optimistic bias and opinion about HPV vaccine, which would be assessed and well managed in tailored HPV education for enhancing HPV vaccine acceptance.

The purpose of this research is to find out how festival servicescape and human service impact the participant's emotional response and behavioral intention in terms of participants as consumers. The servicescape of festival indicated 4 common factors, named cleanliness, convenience, suitability and attravtiveness. As a result of analysis, it indicated that cleanliness and convenience from among the servicescape of festival variables are positively on positive emotion, negatively on negative emotion. And it was analyzed that all the variables of human service influence significantly on emotional response. Especially, it showed that expertise of human service variables influence on positive emotion the most, influence significantly on negative emotion. The result of relationship on behavioral intention indicated that the convenience factor of festival servicescape and expertise factor of human service influence significantly. Therefore, to operate successful festival, festival organizer should plan and manage the festival based on factors which comprises festival servicescape and human service.

This study investigates the influences of shopping enjoyment and risk reduction on customers' attitude and the behavioral intention in the Internet shopping mall using a moving virtual model. For this study, we produced a moving virtual model to present a fashion product. The virtual model walks for about one minute on the stage. After respondents viewed it, they completed a questionnaire. The questionnaire consists of online shopping enjoyment, risk reduction, customers' attitude and behavioral intention. Respondents are limited to females aged in their 20s and 30s, who have experienced Internet shopping and are highly interested in fashion products. 411 samples were used for the final analysis. Cronbach's alpha, factor analysis, and multiple regression analysis were conducted. The results are as follows. Online shopping enjoyment and risk reduction influenced the behavioral intention directly as well as through the attitude. However, the size of the influence indicated that online shopping enjoyment is larger than risk reduction. Therefore, Internet malls should utilize the moving virtual model to provide customers with enjoyment and risk reduction, which will increase customers' favorable attitudes and the behavioral intention such as purchase intention and word of mouth.

Purpose: The present study was designed to find out how the quality of the work environment felt by physical therapists and LMX affect the turnover intention. In addition, we tried to find the mediating effect of LMX in the causal relationship between work environment quality and turnover intention, and to find ways to effectively lower the turnover intention of physical therapists. Methods: Survey tool has obtained validity and reliability through literature survey, exploratory survey and pretest and sample 365 was selected. To treat a pretest and main analysis, SPSS23.0 and AMOS23.0 were employed and structural equation model was employed as an analysis method. Results: Among the work environments, the human environment, the physical environment, and the compensation system were found to have an effect on LMX. In addition, the physical environment and compensation system were found to have a significant effect on turnover intention. LMX was found to have an effect on turnover intention and play a mediating role. Conclusion: In order to lower the turnover intention of physical therapists, the level of LMX should be increased by strengthening the factors of the working environment. This study shows that the management of LMX along with the working environment is an important factor in lowering the turnover intention of physical therapists, and this study has several limitations.

The SPSS package was used for data analysis whose methods included factor analysis, ANOVA, cluster analysis and regression analysis. The results of this study were as follows: First, the service quality factors were determined to be reliability, diversity, convenience, accuracy & communicability. Differences among the groups divided by service quality factors were found to be meaningful in consumer satisfaction and word of mouth intention. Second, reliability, diversity, convenience & accuracy significantly affected consumer satisfaction, however all the service quality factors significantly effected word of mouth intention. Finally, consumer satisfaction, reliability, diversity, accuracy & communicability had an significant effect on word of mouth intention. It would be helpful for the managers of internet shopping malls that consumers can be satisfied with right fashion products and efficient inter-communication based on trustfulness in the long-term relationship.
