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 examined the social capital and geographical gaps of local television stations using web data gathered through website crawling. URLs for 16 local MBC websites were collected. MBC is an abbreviation for Munhwa Broadcasting Corporation, one of South Korea's largest television and radio broadcasters. Munhwa is a Sino-Korean term that means "culture." It initially determined which institutions local broadcasting stations were linked to using a Web Impact Report. To investigate the specific connection type, URL information was classified using the n-tuple helix model, followed by 2-mode network analysis. The n-tuple helix model is an analysis method that extends the standard university-business-government triple-helix model by including a new network innovation originator. As a result, local broadcasting stations relied heavily on activities like as festivals, performances, and exhibitions to engage the local community. Local stations in Daegu-Gyeongbuk area and the Busan-Ulsan-Gyeongnam area were identified as having the most diverse connections to the local population among other regions.

Gyeonggi Province has established a bus information system to provide real-time bus arrival information, aiming to make bus usage convenient for its residents. While the Gyeonggi bus information system is becoming more advanced through the application of IT technology, there are still information-vulnerable groups finding it difficult to use. In particular, the elderly have a low level of digital information literacy and habe difficulty using it. In this regard, this study aims to address the information usage disparity among the elderly in public transportation by utilizing expert in-depth survey methodology known as the Delphi technique. The study classified the policy initiatives that Gyeonggi Province should undertake into three categories: user education and expanded promotion, technological development and dissemination, and providing convenient usage environment. Through two rounds of surveys, the study assessed the priority of ten specific sub-tasks within these categories. Additionally, it gathered opinions on the effectiveness and feasibility of each item. The results yielded prioritization and evaluation of effectiveness and feasibility for nine sub-tasks. Based on these outcomes, the study proposed future projects that Gyeonggi Province should implement to address the information disparity among the elderly, offering a comprehensive approach to bridge the gap.

Digital accessibility of the middle-aged and elderly has been increasing at a faster pace than other groups such as the handicapped and adolescents. However, studies related to the digital accessibility of middle and older adults are scarce. In order to examine variables affecting accessibility to digital information of the middle-aged and elderly people, this study researches the impacts of sociodemographic, physical and mental health and social activity variables on the accessibility of digital information. We analyzed data of 1,661 people between the ages of 55 and 84 from the 2018 Status Survey on Digital Divide conducted by the National Information Society Agency. The hierarchical multiple regression analysis shows the higher education, economic, and life satisfaction levels are, the higher digital accessibility levels of both male and female are. The result of the analysis also shows that the aged male has a higher accessibility level when he does not live alone; meanwhile, the aged female has higher digital capability as her age is lower, which describes that there are differences between gender. We expect the result of this study to be used as an important reference to understand factors related to digital accessibility level and active intervention for improving digital accessibility of the middle-aged and elderly male and female.

This study aims to investigate the factors influencing the life satisfaction of North Korean defectors in the ongoing situation of difficulties. Specifically, it examines the impact of the digital informatization level, and social capital on their life satisfaction and aims to verify the mediating effect of social capital in the relationship between the digital informatization level and life satisfaction. To achieve this, a structural equation model was utilized to validate the research model using data from 679 North Korean defectors who participated in the 2021 Report on the digital Divide. The research results confirm the direct influence of the digital informatization level and social capital of North Korean defectors on life satisfaction. Additionally, the study identifies the mediating effect of social capital in the relationship between the digital informatization level and life satisfaction. Based on these research findings, recommendations are proposed for enhancing the life satisfaction of North Korean defectors.

정보통신기술 특히 인터넷의 급속한 확산으로 웹은 특정계층의 도구가 아니라 모두에게 평등한 보편적 서비스로 자리매김하고 있지만, 장애인 노인 등의 정보취약계층은 이러한 인터넷을 활용하지 못해 불이익을 받는 정보격차(Digital Divide) 현상이 나타나고 있다. 인터넷에 접근하지 못하고 활용하지 못하는 근본적 원인은 웹 접근성(Web Accessibility)의 부재라 할 수 있다. 이에 본 논문에서는 국내외 언론사 홈페이지의 웹 접근성을 평가 비교하여 웹 접근성에 대한 관심을 증가시키고 웹 접근성의 향상 방안을 제시하였다.

Recently, a digital divide has gotten worse in the information age. So LG Sangnam library developed the ubiquitous library for the improvement of information accessability of the blind. It utilizes a mobile phone applied with NFC (Near Field Communication) technology and automates a user's identification process and serve library services at anytime from anywhere. Users can use three access points of a web service, a mobile service and a telephone library service. As a conclusion of this paper. Several recommendations were proposed. For the development of ubiquitous library, various instruments should be considered to diversify user's access points and a usability test and analysis about user's environmental context should be done simultaneously.
