This paper describes a novel navigation algorithm using a locomotion interface with two 6-DOF programmable foot platforms. When a human walks on the locomotion interface (LI), the walking motions of the human are recognized by several sensors. Then, the sensed information is used by the LI for generation of infinite surfaces for continuous walking and the virtual environments for scene update according to motions of the human walking. The suggested novel navigation system can induce user's real walking and generate realistic visual feedback during navigation. A novel navigation algorithm is suggested to allow natural navigation in virtual environments by utilizing conditions of normal gait analysis. For realistic visual feedback, the virtual environment is designed with three components; 3D object modeler for buildings and terrains, scene manager and communication manager component. From experiments, the subjects were satisfied with the reality of the suggested navigation algorithm using the locomotion interface. Therefore, the suggested navigation system can allow a user to explore into various virtual terrains with real walking and realistic visual feedback.

Patella surgery of small animal is an important veterinary surgery that the veterinarian should saw and drill the dislocated patella in order to fix the corrected position. However, the animal protection laws restrict the veterinarian students' chances for the practice and training of the patella surgery. This paper proposed a haptic based patella surgery simulator for veterinarian students. We modelled force feedback methods in order to provide best similar haptic feedbacks to the real drilling feedbacks in the patella surgery. The proposed patella drilling simulator provides haptic interface as a drill and a workbench in order to provide best surgery experiences. We conducted the performance evaluations in order to prove usability of the proposed patella surgery interface.

When enjoying sports activities with friends or others, sportswear has symbolic meanings to express and expect self-concept. Sports players sometimes have trouble when they feel embarrassed by their low skills or care about other people too much. Therefore, researchers tried to find out which feature of sports players affects dependence on brand sportswear along with the effect of wearing conspicuous sportswear on wearer when sports players have a conflict based on Solomon's symbolic interactionism. We proposed that role knowledge and attention to social comparison information (ATSCI) influenced people to depend on and use brand sportswear that influences a reflexive evaluation. Finally, we suggested that a changed self-concept would exert influence commitment to sports. A quantitative study was conducted employing an online survey of 121 people by convenient sampling. In this process, Google Docs was to create the online survey and to collect responses by participants. In data processing, via SPSS 21.0 version for Windows, exploratory factor analysis, Cronbach's ${\alpha}$, ANOVA, t-test, discriminant and regression analysis were conducted to study the relationship between variables. The finding provided evidence that low role knowledge and high ATSCI create high dependence on brand sportswear and influence people to buy sportswear. When people bought and wore a brand sportswear, they evaluated themselves as professional sports players who were more committed to sports. This study confirmed that brand sportswear was useful for sport players to change self-evaluation and enjoy sports.

The objective of this study were to (1) investigate the relationship between evaluations of apparel advertising, fashion involvement, and social attitudes, (2) examine how evaluation of apparel advertising, fashion involvement, and social attitudes vary according to gender, and (3) investigate the possible differences in purchase attitudes toward the advertised apparels according to gender and advertisement slogan. Questionnaire for evaluations of apparel advertising was comprised of four sections; apparel advertising acceptance, evaluation of advertisement slogan, purchase attitude toward the advertised apparels, and perception of effective media for apparel advertising. For evaluation of advertisement slogan, 5 sets of apparel advertisements were selected. Each set had two advertisements; one advertisement contained an image-oriented slogan, while the other had a quality-oriented slogan. "The Social Attitude Scale' by Kerlinger and 'Fashion Involvement Index' by Tigert, Ring & King were used. All the items were selected on the Cronbach's alpha reliability. The subjects were 217 college male and famale students in Seoul; 60 were asked about purchase attitude toward the image-oriented slogan, 60 purchase attitude toward the quality-oriented slogan, and 97 all the items included in evaluation of the two slogans. The data were analyzed using Pearson's correlation coefficient, X2-test, t-test, two-way ANOVA, and multiple regression analysis. The results of the study were the followings. 1. Fashion involvement had positive relationship with apparel advertising acceptance. The higher the level of conservative attitude males had, the more positive attitude they had in fashion involvement and apparel advertising acceptance. Subjects high in conservative attitude, fashion involvement, and apparel advertising acceptance. Subjects high in conservative attitude, fashion involvement, and apparel advertising acceptance had more positive in purchase of the advertised apparels. 2. Females high in apparel advertising acceptance were more favorable toward image-oriented advertisements. 3. Fashion involvement and apparel advertising acceptance were significantly higher in females than in males. Liberal attitude was significantly higher in males than in females. Evaluation of advertisement slogan did not differ according to gender. 4. Males perceived 'TV' was the most effective media for apparel advertising while females perceived 'display' was the most effective. 5. No significant interactions between advertisement slogan and gender were found in purchase attitude of the advertising apparels. 6. Apparel advertising acceptance was influenced by fashion involvement, social attitude, and sex. The explanatory power of the three variables was 17%.

This study approached EPL learning with deductive teaching and learning methods and inductive teaching and learning methods which are grammar teaching and learning methods. In the entry site, lectures provided for elementary school students in grades 5 to 6 were set as deductive learning courses. Based on this, inductive learning process was developed and each learning process was composed of 12 periods. After conducting the research, EPL utilization evaluation, learning satisfaction and immersion test were conducted between the two groups. It was difficult to obtain statistically meaningful results between the two groups. However, in the three tests, the mean value of groups using inductive teaching and learning methods was high. If we construct a long-term learning process and conduct research, we think that statistically meaningful results are produced between the two groups.

This study examined how the memory effect and the brand attitude effect differ according to the interaction (high / low) and the involvement (high / low) of digital signage. The two-way MANOVA analysis using SPSS 18 was used for the empirical analysis. The results of this study are as follows: First, GRM is recalled if the level of interactivity and inffence of digital signage is low, but if both conditions are high, ARM recalls. Second, if the interaction of digital signage is low and the level of engagement is high, a lot of memory information is formed that forms the overall attitude of the product. In addition, even though the interaction level is high and the engagement is low, the attitude cognitive response through the overall evaluation is formed rather than the attribute information. Third, brand attitude was positive when interactivity level was high and engagement level was high.
