  • The necessity of an empirical study on how projection mapping videos are evaluated from consumers' point of view has arisen, as they can lead to visual pollution if factors including spatial characteristics around the structure and details of the contents are not taken into consideration. This study aims to evaluate projection mapping videos and elucidate the question on whether evaluation criteria positively influence the satisfaction level or not. Above all, five evaluation criteria including artistry, creativity, identity, immersion and usefulness were deducted and a hypothesis from preceding research "each evaluation criteria will positively(+) influence the satisfaction level of projection mapping video" has been established. In order to test the hypothesis, big domestic department stores which screened projection mapping videos were selected and a verification experiment has been conducted with ordinary citizens as subjects. In the result of the experiment, among the five evaluation criteria, artistry, creativity, and usefulness were chosen, while identity and immersion were dismissed. The result verifies that if useful information is provided in forms of interesting contents produced with distinctive ideas and creative methods, it will satisfy the consumers as attractive public design.

  • This paper proposes a framework of superpixel-based vehicle detection method using plane normal vector in disparity space. We utilize two common factors for detecting vehicles: Hypothesis Generation (HG) and Hypothesis Verification (HV). At the stage of HG, we set the regions of interest (ROI) by estimating the lane, and track them to reduce computational cost of the overall processes. The image is then divided into compact superpixels, each of which is viewed as a plane composed of the normal vector in disparity space. After that, the representative normal vector is computed at a superpixel-level, which alleviates the well-known problems of conventional color-based and depth-based approaches. Based on the assumption that the central-bottom of the input image is always on the navigable region, the road and obstacle candidates are simultaneously extracted by the plane normal vectors obtained from K-means algorithm. At the stage of HV, the separated obstacle candidates are verified by employing HOG and SVM as for a feature and classifying function, respectively. To achieve this, we trained SVM classifier by HOG features of KITTI training dataset. The experimental results demonstrate that the proposed vehicle detection system outperforms the conventional HOG-based methods qualitatively and quantitatively.

  • Purpose - The year 2016 marks 20 years since the opening of Korean distribution market in 1996. After this opening, the domestic market expanded and modernized, and has grown to become an advanced distribution market with a greater range of consumer choices. On the other hand, traditional markets have waned and their management has become worse. However, traditional markets do not have economic value alone. This study examines the effects of social value in traditional market such as the value of Cultural Tourism and the value of Sharing Community with Traditional Market on Satisfaction, Loyalty and Place Attachment of the residents. Research design, data and methodology - A questionnaire was organized for this study after a hypothesis was set based on theoretical background. Verification of the hypothesis was undertaken by statistically analyzing questionnaire responses. Personal interviews were performed for this study, and a total of 300 responses were collected, of which 228 responses (76%) were from women. The survey coverage was divided into 10 regions ranging from metropolitan areas to the provincial level, and the age groups were divided into 30s to 60s to ensure diversity of the area and age. Results - To summarize the study results, through verification of the hypothesis in terms of meaningful influence, it appears the values of Cultural Tourism to Satisfaction and Loyalty are supported. On the other hand, the value of Sharing Community is only supported for Satisfaction. It appears that Satisfaction to Loyalty and Loyalty to Place Attachment are meaningful effects. The mediator effect was also reconciled through satisfaction and loyalty. Loyalty was analyzed in terms of mediating the effect of satisfaction on place attachment. Conclusions - It is noted in this study that government support is required to preserve traditional markets and renewal program. Community requires multilateral communication and the formation of effective relationships. In contrast to the economic value emphasized by large retailers, the empirical analysis of the non-economic effects of traditional markets has presented the significance of socio-cultural values in traditional markets. In the future, socio-cultural values and economic values should be integrated into more empirical studies through mutual comparison. Investigating the increase and decrease of social value in traditional markets will help the future formulation in government policy.

  • This study examined the relationship between demographic characteristics, satisfaction of operating factors in college lifelong education, satisfaction of college lifelong education, and recommendation intention for 1,782 adult learners of college lifelong education (N=1782). As a result of Hypothesis 1, gender and age were found to have a significant effect in all areas of college lifelong education satisfaction (education content, pedagogy, instructor, educational environment, system, support), while education level did not. In addition, the learning time was verified to affect only the educational content, educational environment, and satisfaction with the system and support. As a result of Hypothesis 2, it was found that the satisfaction of the operating factors of the instructor, system, and support had a positive effect on the satisfaction of college lifelong education, and the environmental factors of education had a negative effect. As a result of verification of Hypothesis 3, it was found that the satisfaction of college lifelong education influenced the intention of recommendation. The purpose of this study is to determine the degree of satisfaction with the operational factors of college lifelong education, the satisfaction of college lifelong education, and the intention of recommendation for adult learners of a university that is operating a degree program dedicated to adult learners who are actually practicing the transition to a lifelong education system of university as an innovation in higher education. The relationship verification is expected to provide practical implications for constructing a new college lifelong education model in the future.
