The purpose of this study is to examine the impact of North Korean defectors' ability to use mobile devices on life satisfaction and to verify whether self-efficacy mediates this relationship. To this end, among the data on the digital information gap conducted in 2022, responses from 607 people wereanalyzed using a structural equation model using SPSS 25.0 and AMOS 24.0, with the ability to use mobile devices as the independent variable, life satisfaction as the dependent variable, and self-efficacy as the parameter. As a result, North Korean defectors' ability to use mobile devices was found to have a positive effect on life satisfaction. In addition, improving the ability to use mobile devices was found to increase self-efficacy. North Korean defectors' ability to use mobile devices was found to have a positive effect on life satisfaction through a positive effect on self-efficacy. As a result of checking the statistical significance of the indirect effect of self-efficacy through bootstrapping, it was found to be significant. Based on these results, practical and policy efforts to improve accessibility, such as education to improve North Korean defectors' ability to use mobile devices, were suggested.

This study empirically analyzes the impact of digital divide between digital device usage motivation and operational skills on online political participation. The analysis was performed using the National Information Society Agency's 2018 digital divide survey data from September to December 2018 and applying the Heckman selection model to control the sample selection bias that may occur between internet users and non-users. The result shows the gap in motivation and device operational skills of individual citizens using digital devices has significant impact on online political participation. In socio-economic terms, it shows the age, education level and regional factors also have significant impact on online political participation, while gender and income levels do not. This study holds significance in that there are different patterns of digital divide between digital devices, identifying the motivation to use a digital device as an important factor for mobile device users, and the device operational skills, for personal computer users.
