This study is to analyze the concentration of visual perception of the subject through the eye-tracking experiments targeting popular characters and to investigate it is effective to highlight which part of the character in inducing consumers' interest and curiosity. As a result of the study, the subjects paid more attention to the face than the character's body, and also noted a little attention to auxiliary elements such as pants, tees, shoes, and whiskers. These results mean there is clearly different factor in which the subject's gaze on the character frequently stays and does for a long time. Therefore, the designers should recognize the differences of the concentration of visual perception by character components as a differentiating factor to feel the emotional satisfaction such as the user's interest, empathy, and immersion in the character and actively reflect it when developing the character design. In addition, there was a difference in the visual perception concentration of each of the auxiliary elements, and if careful research is done on whether the influence factors are also due to individual characteristics or another influential factors, it will be a wider study on character design.

The purpose of this study is to suggest the Assessment model for tourist information center in Seoul. As a research method, we analyzed international guideline and interview with tourism experts in order to rate the tourist centers in Seoul. Secondly, we renamed the international rating model to Itaewon information center as a typical landmark in Seoul. The assessment factors for T.I.C is assembled through researching of the centers' status in terms of overall service satisfaction. Via in - depth interview with 9 visitors, as a result, we were able to derive the possibility that new-designed rating model is able to be applied to the Tourist centers in Seoul. It is significant that this study suggests ways to improve domestic tourist center service. It is expected that the follow - up study will help improve the factors to Seoul T.I.C, not only Itaewon, with much more specific rating method.

Despite the importance of information technology, research on information-oriented performance management and performance management methods are very insufficient. In this paper, the SSU-ITPM model, a company-wide informatization performance evaluation and management model that reflects the characteristics of the shipbuilding and marine industry with high cooperative and process complexity, was presented. This model consisted of informatization planning and project management, informatization field utilization evaluation, informatization utilization quality evaluation, informatization user satisfaction evaluation, and informatization effect achievement evaluation. In addition, through the application of Company D, the feasibility of practical application of the model was confirmed. This study is expected to provide a practical reference model for informatization performance management of ETO plant-based companies such as the shipbuilding and offshore sector.

In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

Domestic delivery app services are taking a leap forward as the non-face-to-face culture spreads due to the COVID 19 situation and the industrial scale is also growing. In the expanding delivery app service market, we try to verify the structural relationship between variables by empirically analyzing the influencing factors of users' trust in rational and emotional factors. Delivery app service users trust and discriminate parameters in the relationship between rational and emotional factors. Satisfaction according to the trust of a valid delivery app service and service expansion model through word of mouth was designed. It was verified through a hypothesis whether it had an effect, and it can be used as a variety of service strategies for delivery app service users.

The Korean maritime industry is growing rapidly as income levels rise. In particular, the domestic yacht market is generating steady market demand, which is a good opportunity for users who want to enjoy leisure. Among them, the experience-type yacht is operated smoothly around Suyeong Bay in Busan. In this study, a survey of experienced yacht users conducted an analysis focusing on color as much as the interior structure. The colors you experience when you stay in a specific space for a short time have a significant impact on the user's satisfaction and sensibility. Often, systematic research into space is often focused on physical distribution. However, color leaves a strong impression on short experiences as much information as it accepts through the optic nerve. A survey of yacht passengers was conducted to derive appropriate adjectives, and the results were obtained after analyzing them by means of I.R.I monochrome and image scale. Afterwards, it is expected that this research will be used as a theoretical basic data that can be used to carry out the production, repair, and repair of hands-on yachts that are developed on their own.

Recently, large online shopping malls are providing image search services as well as text or category searches. However, in the case of an image search service, there is a problem in that the search service cannot be used in the absence of an image. This paper describes the development of a system that allows users to find the clothes they want through hand-drawn images of the style of clothes when they search for clothes in an online clothing shopping mall. The hand-drawing data drawn by the user increases the accuracy of matching through neural network learning, and enables matching of clothes using various object detection algorithms. This is expected to increase customer satisfaction with online shopping by allowing users to quickly search for clothing they are looking for.
