Contactless service is rapidly emerging as a new growth strategy due to consumers who are reluctant to the face-to-face situation in the global pandemic of coronavirus disease 2019 (COVID-19), and various technologies are being developed to support the fast-growing contactless service market. In particular, the restaurant industry is one of the most desperate industrial fields requiring technologies for contactless service, and the representative technical case should be a kiosk, which has the advantage of reducing labor costs for the restaurant owners and provides psychological relaxation and satisfaction to the customer. In this paper, we propose a solution to the restaurant's store operation through the unmanned kiosk using a state-of-the-art artificial intelligence (AI) technology of image recognition. Especially, for the products that do not have barcodes in bakeries, fresh foods (fruits, vegetables, etc.), and autonomous restaurants on highways, which cause increased labor costs and many hassles, our proposed system should be very useful. The proposed system recognizes products without barcodes on the ground of image-based AI algorithm technology and makes automatic payments. To test the proposed system feasibility, we established an AI vision system using a commercial camera and conducted an image recognition test by training object detection AI models using donut images. The proposed system has a self-learning system with mismatched information in operation. The self-learning AI technology allows us to upgrade the recognition performance continuously. We proposed a fully automated payment system with AI vision technology and showed system feasibility by the performance test. The system realizes contactless service for self-checkout in the restaurant business area and improves the cost-saving in managing human resources.

Since the 1990s, digital technology has been actively applied in the field of heritage, and this presents a new possibility of using cultural heritage as a way to utilize the original cultural data that was previously recorded and stored. Methods of interpreting cultural heritage have been particularly diversified due to various external circumstances such as COVID-19 and time constraints, and the use of contactless digital content has played a significant role in built heritage that cannot be moved. Building Information Modeling (BIM) technology is considered as a way to properly express the authenticity of built heritage, but simply creating built heritage content with BIM cannot express the authenticity of cultural heritage. Therefore, it is necessary to show the reliability of the process of content production through an authorized institution and to provide the information of members on the content. This study intends to contribute to the field of digital heritage by suggesting ways to improve reliability and express authenticity in the production of built heritage content.

In this paper, we design and implement a product information guidance system Based on BLE beacons. This system is designed to provide various functions such as contactless entrance service through mobile ticket, seat guidance service, event push service, content push service, and public service. This system consists of three modules: a beacon recognition module, a server linkage module, and a content transmission module. The beacon recognition module implements a function of transmitting a specific ID of a nearby beacon when a customer with a smartphone approaches the available service area. The server linkage module recognizes the beacon ID value, transfers it to the server, and implements the function to check the location of the server having the ID. The content transmission module implements a function of transmitting event or service information set at a corresponding location to a smartphone. The beacon-based product information guidance system implemented in this paper has the advantage of being able to quickly and easily implement various product information guidance systems.

The purpose of this study was to establish the concept of self-management in beauty service experts through two integrated research methods of open-ended questionnaires and focus group interview. For data collection, an open-ended questionnaire was conducted for 151 beauty service experts located in Seoul·Gyeonggi-do, and a focus group interview was conducted with 8 experts in beauty experts to collect data. Accordingly, the results derived through a series of research procedures are as follows. First, as a result of the inductive content analysis of the open questionnaire, the self-management of beauty service experts was derived into four types of intellectual management: health management, interpersonal management, appearance management, and technology management. Second, in the results of the focus group interview, the inductive content analysis was more validly supported, and the beauty service field-centered interview cases were dealt with in-depth, resulting in two additional attributes of contactless management and knowledge management. The results of this study can be used as basic data for establishing strategies for life as a successful professional of beauty service workers and developing self-management measurement tools for beauty service experts.

Recently many organizations have adopted 'untact' work due to social distancing caused by Coronavirus-19. To clarify some controversy about the effectiveness from 'untact' work, it is necessary to examine the cognition of organizational members. This study identified issues in 'untact' work from the literature review, analyzed the content of in-depth interviews with workers and managers experiencing 'untact' work, and compared both groups' cognition by applying the co-orientation model. Both groups pointed out the communication difficulty as the top disadvantage and showed no significant differences in job satisfaction, organizational commitment, and work-life balance. However, the two groups showed significant differences in their cognition about performance evaluation (agreement and workers' congruence) and productivity enhancement (workers' accuracy). This paper has an academic contribution in that it has focused on cognitive gaps between workers and managers, urges organizations to devise ways to reduce the gaps, and suggests future studies with quantitative approaches.
