Most humans live at work and continue their lives through work. This study aims to understand the influence of job crafting on job satisfaction and knowledge sharing behavior, innovation behavior, and smart work environment variables in the rapidly changing labor market. In addition, a study was conducted on the effect of job crafting on job satisfaction by dividing it into male and female groups. The study was conducted on 453 office workers who responded to the survey, and SPSS 26.0 and Amos 26.0 were used. Frequency analysis, exploratory factor analysis, confirmatory factor analysis, reliability analysis, descriptive statistics, correlation, structural model analysis and Multi-group analysis were performed. Multiple mediating effects were analyzed and Process macro model 7 was used as the smart work environment effect. As a result of the analysis, first, job crafting had a significant effect on job satisfaction, and second, job crafting had a significant effect on knowledge sharing behavior and innovation behavior. Third, knowledge sharing behavior had a significant effect on job satisfaction, but innovation behavior did not affect job satisfaction. Fourth, for the parameters of knowledge sharing behavior and innovation behavior, knowledge sharing behavior had a partial mediating effect, but innovation behavior did not affect it. Fifth, it was found that the moderating effect of the smart work environment had no effect, and sixth, the results of a study on the effect of job crafting on job satisfaction divided into men and women had a greater effect than men.

This study analyzed whether depression and social support had a mediating effect between income status and life satisfaction of middle-aged and elderly people with disabilities using data from the 15th year of the Korea Welfare Panel data. As a result of the analysis, first, the income status of the middle-aged and disabled was depressed(B=.241, p<.001), social support(B=-.167, p<.001), and life satisfaction(B=-.277, p<.001) was confirmed to have a direct effect. Second, the mediating effect of depression and social support was verified on the influence between the income status of middle-aged and disabled people between life satisfaction. Third, it was confirmed that depression and social support had a multi-mediating effect between the income status and life satisfaction of middle-aged and disabled people. Therefore, an income support system that supports middle-aged and disabled people to live at an appropriate level should be prepared. In addition, in order to increase the life satisfaction of middle-aged and disabled people, it is necessary to intervene in mental health support services that can actively cope with depression and to expand the social support network.

One of the most important types of Customer Empowerment Strategy (CES) is select empowerment, where firms allow customers to vote on a product to be marketed. However, there is limited research on the advantages and disadvantages of select empowerment. In particular, there are few studies on the composition of a voting system. This study analyzes customer participation behavior, such as willingness to vote and strategic voting (i.e., voting for candidates not based on utility orders), under the different voting systems: 1) the number of votes per customer (single or multiple), and 2) the number of final choices (single or multiple). Uncertainty is proposed as a mediator that links the voting system difference and customer participation. Two research hypotheses are tested using multiple linear regression analysis and a natural effects model based on data from two online experiments. As a result, the multiple voting system (i.e., multiple winners are selected by customer votes) shows a direct positive effect on willingness to vote and strategic voting behavior. In addition, the result shows that uncertainty insignificantly mediates the relationship between the voting system and customer participation. Academic and managerial contributions are discussed with several future research directions.

This study aims to examine whether assets matter for depression among older adults and whether the relationship between assets and depression is mediated by social activities. The research questions are based on asset effect theory, stakeholder theory, and activity theory. This study used the 5th wave of KLoSA data which is a nationally representative data in Korea. Research findings are summarized as follows: First, we found the negative relationship between assets and depression of older adults. Second, The relationship between assets and depression was partially mediated by social activities of older adults. The findings suggest that older adults with assets are more likely to participate in social activities and accordingly their depression is likely to decline. Based on the empirical findings, we can propose that asset-building programs targeting older adults should be developed and that the financial education and saving chances should be given to middle-aged adults who need to prepare old age in the long-term perspective.

This study seeks to find a way to induce users to expand their direct participation in sports through the acceptance of digital technology. From July 1 to August 30, 2022, a survey was conducted targeting home training users who applied the Internet of Things (IoT). 129 people participated in the survey through non-face-to-face self-administration method. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and 3-step mediation regression analysis were conducted using IBM's SPSS 21.0 program. The results of the study are as follows. First, in the relationship between the home training PPM model and direct participation in sports, ease appeared to have a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. In the mooring factors, individual innovativeness showed a complete mediating effect. Second, in the relationship between home training PPM model and direct participation in sports, usefulness showed a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. Among the mooring factors, individual innovativeness showed a partial mediating effect. Through this research, it is expected that the sports industry will contribute to the expansion of consumption expenditure and economic growth through the expansion of digital technologies such as NFT, Metaverse, and virtual/augmented reality.

The purpose of this study is to investigate how level of digital information usage of the middle-aged or elderly people affects life satisfaction and whether social capital mediates the relationship between level of digital information usage and life satisfaction. In this study, we analyzed data of 1,661 people aged 55 or older from the 「2018 Survey on Digital divide」 by the National Information Society Agency. The SPSS 25.0 statistical package was used for the mutiple regression analysis and Baron and Kenny(1986)'s steps for mediation. The statistical significance of the mediated effects of social capital was verified by the Sobel Test. As a result of the analysis, the aged people have a higher life satisfaction when they are women and older, do not live alone, have higher levels of digital informatization usage and social capital. In addition, social capital also revealed to have a mediating role between level of digital information usage and life satisfaction. This shows that social capital needs to be considered along with the level of digital information usage as a way to improve life satisfaction of the middle-aged or the elderly people.
