The recent steep increase in the minimum hourly wage has increased the burden of labor costs, and the share of unmanned stores is increasing in the aftermath of COVID-19. As a result, theft crimes targeting unmanned stores are also increasing, and the "Just Walk Out" system is introduced to prevent such thefts, and LiDAR sensors, weight sensors, etc. are used or manually checked through continuous CCTV monitoring. However, the more expensive sensors are used, the higher the initial cost of operating the store and the higher the cost in many ways, and CCTV verification is difficult for managers to monitor around the clock and is limited in use. In this paper, we would like to propose an AI image processing fusion algorithm that can solve these sensors or human-dependent parts and detect customers who perform abnormal behaviors such as theft at low costs that can be used in unmanned stores and provide cloud-based notifications. In addition, this paper verifies the accuracy of each algorithm based on behavior pattern data collected from unmanned stores through motion capture using mediapipe, object detection using YOLO, and fusion algorithm and proves the performance of the convergence algorithm through various scenario designs.

This study aims to analyze online game user's game items transacting behaviors for the two game genres such as MMORPG and sports game. For the sake of conducting the analysis, we adopted a fuzzy logic agent-based modeling. In the online game fields, game items transactions are crucial to game company's profitability. However, there are lack of previous studies investigating the online game user's game items transacting activities. Since many factors need to be addressed in a complicated way, ABM (agent-based modeling) simulation mechanism is adopted. Besides, a fuzzy logic is also considered due to the fact that a number of uncertainties and ambiguities exist with respect to online game user's complex behaviors in transacting game items. Simulation results from applying the fuzzy logic ABM method revealed that MMORPG game users are motivated to pay expensive price for high-performance game items, while sports game users tend to transact game items within a reasonable price range. We could conclude that the proposed fuzzy logic ABM simulation mechanism proved to be very useful in organizing an effective strategy for online game items management and customers retention.

This study deals with the influencing factors for satisfaction and the emotional value perception of mobile voucher service user. Thus researcher examined a structural equation modeling methodology of the paths within word of mouth, satisfaction, and other exogenous variables (economic/rational value, trust, joyfulness, innovativeness). As a result of this study, First, it was confirmed that the emotional value, and innovativeness affected user's trust for coupon service and joyfulness for using mobile voucher. Second, it was confirmed that trust and joyfulness affected user's satisfaction and word of mouth activities. Therefore, in cases of utilizing the emotional appeal of mobile voucher as part of a marketing tool, corporate can maximize efficiency by using their mobile voucher service & event from the point of view of customer's satisfaction & voluntary word of mouth. Researcher's consideration is that this paper's theoretical and practical contribution point is the propose of the one of the post adoption model with the quantitative study of the mobile voucher service user's emotional perception in the initial development stages of high-tech industry.

Prior researchs on Internet shopping have focused on cognitive, technological factors, but this research is focused on emotions experienced during internet shopping. Examines emotion types experienced during internet shopping and shopping mall characteristics influencing emotional response and effect of emotions on internet shopping behavior, specifically focusing on gender difference The data, collected from a sample of 131 internet shoppers, indicate that emotion types experienced during internet shopping and shopping mall characteristics influencing emotional response and emotional response influencing internet shopping behavior are difference between female and male. Theses results provide insights on internet shopping mall management according to gender.

Today, in order to cope with the changing security environments and the citizen demand actively and efficiently, the Korean police is attempting a great change inside and outside such as the practical application of decentralized police system. Police's corruption is serious in various statistical data that present from lower part that is show. compares to continuous upright improvement effort and evaluation of the inside of the police system. the citizens recognition against it is evaluated lowly. The difference of recognition on police potential integrity between members of the police organization, the citizen and the external agency points the insufficiency of police improvement, deficiency of effective system and policy, organization culture as causes.

Through Tourism Information System, we can know, how much we feel importance of travel information and how to they spending, research when they need to go to travel according to we have to realize about anticipation/planning phase and on-site phase are different exactly. This purpose is how to get a basic data when we support with tourist about information of festival in travel and also how to give satisfaction for tourist and how many tourist wants to join the travels in addition, it is possible to we can develop all of things about travel informations. This is a result of research. First, all of the tourists participate the FESTIVAL, even though they didn't get any informations about travel. The second, information of festival in travel has different feeling between importance of participate in festival and performance after experience.

At this point in time, the importance of cosmeceuticals is being emphasized. This report is about the cosmeceuticals usage analysis of actual condition and purchasing behavior of female undergraduates. I suggest the methods for the sustainable improvement of cosmeceuticals that will satisfy needs of more customers through market segmentation. The subjects of this study were 340 undergraduates of selected 2 women's Universities in Seoul. 300 replies among the total distibuted questionnaires were analyzed with SPSS WIN 15.0 Statistics program. Through the study, it appears that the most female undergraduates use cosmeceuticals and the usage of cosmeceuticals is to resolve their skin problems. The most popular places for the purchase of cosmeceuticals are department stores and the most important consideration on purchases is the effectiveness of products. It is discovered that sunscreens are the most used cosmeceuticals.

Recently, many business organizations have been increasingly expanding the utilization of the intelligent chatbot services for effective customer relation management. The purpose of this study is to empirically investigate the factors which affect the use of the intelligent chatbot services. Above all, the research model and the hypotheses were derived through reviewing the major relevant theories such as UX(user experience) theory(Honeycomb model), TRA(theory of reasoned action), TAM(technology acceptance model) and ETAM(extended TAM). And then, structural equation analyses using SmartPLS 3.0 for 233 valid questionnaires replies collected through the field survey was performed to test the hypotheses. Theoretically, this study can contribute to providing the conceptual framework with regard to enhancing the use of intelligent chatbot services. And practically, this study sheds new light on suggesting the guidelines to designing the UX(user experience) of the intelligent chatbot services.

This paper has analyzed the factors and purchasing places affecting the purchasing caned coffee which is classified into low involvement goods. As the result of research, it was discovered that affected factor has arisen out of distribution or recognition other than satisfaction of goods. Consumers who have low satisfaction level switch but this occasion happen at a much lesser rate than expected and on the contrary, even customers who were lesser satisfied expressed that they would buy the same brand again. Although this paper demonstrates the importance of the distribution and recognition factors (publicity), among other marketing mixes, that play a greater role than the product when purchasing the product, it has not taken the effects of promotion into consideration. In the future, the consequences of promotions should be explored and simultaneously look into how each of the factors influence direct sales and weigh how much impact each factor has.
