With the progress of the 4th industrial revolution, interest in smart factories is increasing. The government is implementing a smart factory support project for small and medium-sized manufacturing companies. Therefore, in this study, factors influencing small and medium-sized enterprises(SME's) intention of smart factory acceptance were analyzed. In particular, it focused on how the perception of government support affects intention of smart factory acceptance. For the empirical analysis, a research model was established by reflecting the characteristics of SMEs and the technical factors of the smart factory centering on the technology acceptance theory. Based on the model set in this way, a questionnaire survey was conducted for employees of SMEs. In this study, a total of 231 samples of valid data were used for analysis. The empirical analysis results are as follows. It was analyzed that performance expectancy, social influence, technology utilization capability, CEO will, and employee resistance to innovation, all introduced as research variables, had a significant effect on the use intention of smart factory acceptance. In particular, it was found that employees' resistance to innovation had a negative (-) effect on their use intention. Meanwhile, to analyze the moderating effect of government support, it was divided into a group with high expectations for government support and a group with low expectations. As a result, it was found that there was a difference in the effect of CEO's will, employees' resistance to innovation, and social influence on the use intention. On the other hand, no significant difference was found in the relationship between performance expectancy, technology utilization capability on the use intention.

Due to the progress of the 4th industrial revolution and the COVID-19 pandemic, the subscription economy was rapidly expanding. In particular, the subscription economy was expected to expand further as the servicing of products(servitization) rapidly progresses. In this study, we tried to empirically analyze the factors that promote and hinder the spread of the subscription economy from the consumer's point of view. To this end, based on the Service Profit Chain (SPC) model, which identified mechanisms leading from quality to satisfaction, loyalty, and performance, a research model was established by combining the framework of the Value-based Adoption Model (VAM), which covers both benefit and sacrifice factors. Usefulness and convenience were derived as benefit factors, and perceived risks and perceived costs were derived as sacrifice factors. The effects of these factors on satisfaction and continuous use intention were analyzed. For empirical analysis, a survey was conducted targeting people who have experience in subscription economy, and 300 effective samples were analyzed. The analysis was performed as a structural equation model using AMOS 24. As a result of the empirical study, it was found that convenience had a significant positive (+) effect on satisfaction. Perceived risk and perceived cost were analyzed to have a negative (-) effect on satisfaction. On the other hand, usefulness was found to have no significant effect on satisfaction. The influences affecting satisfaction were in the order of perceived cost, convenience, and perceived risk. Satisfaction was found to have a significant positive (+) effect on continuous use intention. The results of this study were considered meaningful in that they broadened the horizons of research by combining existing validated models at the academic level and testing their validity, and found that perceived cost was still an important factor at the practical level.

The advancement of IT and the "Fourth Industrial Revolution" blurred the boundary between industries. The importance of strategic cooperation between enterprises is emphasized. IT companies must consider their existing business areas and create new territories to drive changes in the industry. They must also secure their competitive edge and manage economic costs to enable them to compete with their global counterparts. By utilizing their resources effectively, these firms can create value through inter-firm cooperation. This study analyzes the collaborative network of global IT companies using social network analysis and examines the effect of this network on firm performance. Collaborative linkages and betweenness centrality, which represent the bridging position of a firm in a network, significantly affect firm performance. This result highlights the importance of the structural position of a firm in a cooperative network of IT companies. This study also characterizes clusters in a network of IT companies. Most of these clusters comprise a combination of IT companies in diverse IT industries. These clusters suggest that these companies engage in multilateral cooperation without boundaries to maximize their business capabilities. This study offers practical implications for establishing a cooperative strategy and framework that can capture business trends in the IT industry from a macroscopic view. This study also visualizes collaborative networks in a multifaceted way using social network analysis to provide researchers and business practitioners with an informative viewpoint.

As the 4th Industrial Revolution progresses, the importance of startups was increasingly emphasized. Nevertheless, the five-year survival rate of Korean startups was lower than that of OECD countries. In this study, we analyzed the relationship between agile leadership, learning agility, and organizational performance of startups under the premise that organizational performance was most important for startups to achieve sustainable growth. For the empirical analysis, agile leadership was set as an independent variable, learning agility was set as a mediating variable, and organizational performance was set as a dependent variable. Data was collected from startup employees across the country, and 197 valid samples were selected for analysis. The empirical analysis used Process Macro 4.2. As a result of the empirical analysis, agile leadership was found to have a significant positive effect on startup organizational performance. Additionally, agile leadership had a positive (+) effect on learning agility, and learning agility had a positive (+) effect on startup organizational performance. As a result of analyzing the mediating effect of learning agility, learning agility was found to play a mediating role between agile leadership and organizational performance. Academically, these research results tested the usefulness of agile leadership suited to the startup culture among various leadership styles that can improve the organizational performance of startups. In practical terms, such agile leadership not only directly affects organizational performance, but also through the learning agility of startup employees. This means that by creating a culture of learning agility that encourages startup employees to continuously learn and adapt, startups can increase their chances of survival and success.

Purpose of study: The purpose of this study is to suggest the direction of Christian self-identity while paying attention to the metaverse era. It suggests the direction of education that forms a Christian self-identity based on the problems of identity crisis that may arise due to the problem of de-realization while accepting the situation of the metaverse that has emerged due to the digital revolution. Research content and method: Focusing on the discussion of metaverse and de-realization, this paper suggests the importance of Christian self-identity and the direction of education. For this purpose, four tasks of practical theology were carried out based on Richard Osmer's consensus model. As the desciptive-empirical task was carried out, the opportunities and risks of the metaverse were brought up. Through the interpretive task, the problem of metaverse and de-realization was presented. The normative task emphasized the importance of Christian self-identity, and the pragmatic task proposed an education oriented towards Christian self-identity. Conclusions and Suggestions: It is important for education in the metaverse era to form a sense of Christian self-identity. The purpose of education is the formation of Christian's self-identity, and the content is to build the Christian relationality self, equality self, and openness self. The teaching method is interactive teaching, and the teacher and learner can be presented as an encounter between interpreters. The environment is any area of interpreted life, and evaluation can manifest itself in Christian life as disciples and citizens. The suggestion is to suggest compedency education methods for acquiring Christian self-identity while considering various generations.
