Due to the nature of small businesses, different corporate performance was found according to the leadership and marketing capabilities of managers. In particular, the presence or absence of corporate performance was confirmed through the manager's perception of the usability of non-face-to-face services. As a result of conducting a survey of executives of small businesses, it was found that the open leadership and marketing capabilities of small business managers had an effect on corporate performance and also had an effect on the convenience of non-face-to-face service use.

The purpose of this study is to explain intention to use untact medical diagnosis and consultation services. There is a need for untact medical diagnosis and consultation services in order to increase social interests and a global trend for public protection and convenience enhancement. We carry out the analysis of the survey data using Smart PLS 3.0 to test the hypotheses. According to the empirical analysis results, this study confirms that health consciousness have significant effects on the cost saving, quality of telemedicine service and self-efficacy have significant effects on the accessibility, compatibility. cost saving, quality of telemedicine service, accessibility and compatibility have significant effects on Perceived usefulness. Perceived usefulness have significant effects on use Intention of untact medical diagnosis and consultation services. This study has its meaning because it found out that it deals structurally and expansively with use intention through Expected Benefit and usefulness based on individual characteristics for untact medical diagnosis and consultation services. In addition, The results of this study suggest that if the related policies are institutionalized based on the Expected Benefits covered in this study, the perception of untact medical diagnosis and consultation services can be changed progressively.

The purpose of this study is to explain intention to use untact medical diagnosis and consultation services. We carried out the analysis of the survey data using Smart PLS 3.0 to test the hypotheses how the expected benefit variables and perceived risk variables of untact medical diagnosis and consultation services affect intention to use. According to the empirical analysis results, this study confirmed that quality of telemedicine service had a significant effects on perceived usefulness, Perceived Easy of Use. And accessibility had a significant effects on perceived easy of use, cost saving and expected benefits had a significant effects on use Intention of untact medical diagnosis and consultation services. Performance risk and service risk had a significant effect on medical risk. And medical risk had a significant negative(-) effects on use Intention of untact medical diagnosis and consultation services. This study has its meaning because it found out that it deals structurally and expansively with use intention of untact medical diagnosis and consultation services through positive and negative factors.

비대면 문화가 확대됨에 따라 다양한 산업의 서비스가 메타버스와 접목되어 사람들에게 제공되고 있다. 사회적 고립 등의 문제로 상담에 대한 필요성이 높아지고 있음에 주목하여 Unity를 사용해 비대면 상담이 가능한 메타버스 플랫폼을 개발하였다. 본 논문에서는 자연스러운 아바타의 움직임, 카메라의 이동, Firebase와의 데이터 전달과 Photon 동기화 기능들을 가지는 3D 월드맵의 구현에 필요한 기술들을 포함하였다. 기존에 대면으로 진행되는 상담 서비스를 대체하여 심리 상담에 대한 진입 장벽을 낮추고 접근성을 높이고자 하며, 해당 플랫폼은 여러 비즈니스들과 결합할 수 있음에도 그 의의가 있다고 본다.

The purpose of this study is to evaluate the service attributes and consumer reactions of telemedicine apps in South Korea and visualize their differentiation by constructing positioning maps. We crawled 23,219 user reviews of 6 major telemedicine apps in Korea from the Google Play store. Topics were derived by BERTopic modeling, and sentiment scores for each topic were calculated through KoBERT sentiment analysis. As a result, five service characteristics in the application attribute category and three in the medical service category were derived. Based on this, a two-dimensional positioning map was constructed through principal component analysis. This study proposes an objective service evaluation method based on text mining, which has implications. In sum, this study combines empirical statistical methods and text mining techniques based on user review texts of telemedicine apps. It presents a system of service attribute elicitation, sentiment analysis, and product positioning. This can serve as an effective way to objectively diagnose the service quality and consumer responses of telemedicine applications.

최근 비대면 사회가 지속되며 매장에서 각종 키오스크가 더 많이 사용되고 있다. 이는 위생면에서 비대면으로 자유롭게 서비스를 제공받을 수 있고, 말을 하기 어려운 사람들에게 편리함을 제공한다는 장점이 있다. 하지만 디지털 격차가 벌어진 세대에게는 불편함을 느끼게 한다. 이러한 키오스크가 개인에 맞춰 제공받을 서비스를 알려 준다면 문제점을 개선할 수 있다. 본 논문은 얼굴인식과 2차 인증수단을 통해 개인을 식별한 후 맞춤형으로 서비스를 제공하도록 만들었다. 특히 장노년층의 사용이 많은 병원을 대상으로 하여 키오스크의 장점인 높은 편리성과 효율성을 기대할 수 있도록 UI를 구성하였다.

As COVID-19 spread, non-face-to-face activities were required, and the use of service robots is gradually increasing. This paper analyzed the relationship between the increasing trend of service robots before and after COVID-19 through keyword search containing the keyword 'service robot AND non-face-to-face' over the past three years (2018.10-20219) using BigKines, a news big data analysis system. As a result, there were 0 cases in the first period (2018.10~2019.9), 52 cases in the second period (2019.10~2020.9) and 112 cases in the third period (2020.10~2021.9), an increase of 115% compared to the second period. The keywords commonly mentioned in the analysis of related words in the second and third periods were COVID-19, AI, the Ministry of Trade, Industry, and Energy, and LG Electronics, and the weight of COVID-19 was the largest, confirming that the analysis keyword. Due to the spread of Corona 19, non-face-to-face is required, and with the development of information and communication technology, the field of application of service robots is rapidly increasing. Accordingly, for the commercialization of service robots that will lead the non-face-to-face economy, there is an urgent need to nurture human resources that require standardization and expertise in safety and performance fields.

The need for various approaches to non-face-to-face identification technology for registering and authenticating users online is being required because of the growth of online financial services and the rapid development of financial technology. In general, non-face-to-face approaches can be exposed to a greater number of threats than face-to-face approaches. Therefore, identification policies and technologies to verify users by using various factors and channels are being studied in order to complement the risks and to be more reliable non-face-to-face identification methods. One of these new approaches is to collect and verify a large number of personal information of user. Therefore, we propose a big-data based non-face-to-face Identity Proofing method that verifies identity on online based on various and large amount of information of user. The proposed method also provides an identification information management scheme that collects and verifies only the user information required for the identity verification level required by the service. In addition, we propose an identity information sharing model that can provide the information to other service providers so that user can reuse verified identity information. Finally, we prove by implementing a system that verifies and manages only the identity assurance level required by the service through the enhanced user verification in the non-face-to-face identity proofing process.
