The development of technology based on digital technology has made 'hyper connectivity' between different services a reality, and an example of this is the reinforcement of non-face-to-face services. The non-face-to-face service is a service provided by service providers and customers using information and communication and technology without direct contact. Recently, it has expanded to the hotel industry, which is highly dependent on human resources, centering on the restaurant business. Therefore, this study attempted to identify the case of the "R" hotel in the Gangwon region, which is introducing and operating a kiosk, and to confirm the matters to be considered, the system operation method, and expected effects, etc. for hotels that intend to operate it in the future. It is difficult to affirm that the introduction of KIOSK directly reduced labor costs or increased service efficiency, but it seems meaningful that it has improved the convenience of users. In future research, practical research is needed on the impact of the system on management activities in relation to the introduction of KIOSK.

Customer satisfaction in retail stores are considerably affected by checkout services. Self-checkout counters have been installed in order to reduce waiting times at checkout in retail stores. However, it is uncertain whether the self-checkout lanes actually decrease the average waiting time of customers. Rather, there are some problems associated with self-checkout lanes such as theft or service failure due to technological problems. This study analyzes comparison between self-checkout and regular staffed-checkout lanes, based on the dataset collected from a retail store in Poland. As a result, we observe that the average transaction times were longer at the self-checkout lanes though fewer products were purchased than at the staffed-checkout lanes. In addition, the customers who buy more products tend to use self-checkouts less frequently. We also check that transaction times are proportional to the number of products customers purchase, and that both the time to scan one item and the fixed time related to checkout are significantly longer at the self-checkout counters. As there has been very few research on the effectiveness of self-checkouts, this study can be the first step to investigate managerial insights on checkout services in retail stores.

This study is to select an optimal object detection algorithm for designing a self-checkout counter to improve the inconvenience of payment systems for products without existing barcodes. To this end, a performance comparison analysis of YOLO v2, Tiny YOLO v2, and the latest YOLO v5 among deep learning-based object detection algorithms was performed to derive results. In this paper, performance comparison was conducted by forming learning data as an example of 'donut' in a bakery store, and the performance result of YOLO v5 was the highest at 96.9% of mAP. Therefore, YOLO v5 was selected as the artificial intelligence object detection algorithm to be applied in this paper. As a result of performance analysis, when the optimal threshold was set for each donut, the precision and reproduction rate of all donuts exceeded 0.85, and the majority of donuts showed excellent recognition performance of 0.90 or more. We expect that the results of this paper will be helpful as the fundamental data for the development of an automatic payment system using AI self-service technology that is highly usable in the non-face-to-face era.

In this paper, we present a self-adaptive software platform that enables an IoT gateway to perform autonomous operation considering IoT devices connected each other in resource-constrained environments. Based on the oneM2M device software platform publicly available, we have designed an additional part, called SAS (self-adaptive software) consisting of MAM (memory-aware module), NAM (network-aware module), BAM (battery-aware module), DAM (data-aware module), and DH (decision handler). A prototype system is implemented to show the feasibility of the proposed self-adaptive software architecture. Our proposed system demonstrates that it can adaptively adjust the operation of gateway and connected devices to their resource conditions under the desired service scenarios.

When patients have acute cardiac arrest before they are hospitalized, the ratio of CPR done by the general public is directly related to patient survival ratio. However, compared with that of advanced nations, our nation has low patient survival ratio due to its low ratio of CPR done by the general public. To improve this situation, the current study conducted a pre-survey targeting 3,800 general public to find how to apply an emergent medical system using smart phone location-based service. According to its outcome, first, they have a high level of CPR experience while their recognition of CPR generality is low. Second, their self-confidence in doing CPR significantly differ according to their age, academic achievement and occupation yet with generally low self-confidence. Third, their participation in the emergent medical system using location-based service APPs is high, and has co-relation to their will for CPR, self-confidence in CPR and experience in CPR training.
