This study investigates the effects of different types of digital informatization (i.e. access, skill, utilization) on life satisfaction. The mediation effects of the outcome of digital device use between digital informatization and life satisfaction are also tested. The '2020 Survey on the Digital Divide' conducted by the National Information Society Agency was referenced for empirical analysis. The findings show that in general, digital informatization contributes to improving life satisfaction. In addition, the outcome of digital device use mediates the positive relationship between digital informatization and life satisfaction. However, the magnitudes of the effects of digital informatization and mediation effects differed according to the types of digital informatization. This study supports the necessity and justification for a digital informatization policy and provides valuable information that helps establish and promote digital informatization policies. In addition, this study helps to understand the determinants of the third-level digital divide information by examining the relationship between digital informatization and the outcome of digital device use.

The 4th Industrial Revolution and Covid 19 are moving the fashion industry from offline to online. Fashion shows that took place offline are being replaced by online. Online is greatly increasing consumers' digital customer experience based on digital technologies. In this study, we studied the effect of digital experience factors on digital customer satisfaction based on the Schmitt(1999)'s experience marketing. The effect of digital customer satisfaction on purchase, continuous use intention, and recommendation intention were also studied. In addition, the moderating effect of experience frequency was studied. We randomly sampled 180 individuals among fashion mall users.. SPSS 24, AMOS 23 and Process Macro 3.5 were used for statistical analysis. In the study in which digital experience factors influence digital customer satisfaction, all except the digital act showed positive influence. The impact of influence was digital sense (β = .366) > digital think (β = .225)> digital feel (β = .191) > digital relate(β = .163). Digital customer satisfaction have been positive impact on purchasing, continuance use and recommendation intention. In the moderating effect of digital experience frequency, between digital feel, digital act and digital customer experience showed a statistically effective relationship. Based on the this study, We suggested theoretical and practical implications.

In recent years, the number of digital content transaction has increased dramatically, in main, owing to the innovation of IT technology. At the same time, it creates new problems which have never been found in traditional transactions. Especially, due to the easy-copy characteristics of digital content, the illegal usage of digital content proliferates. Also the conflicts between seller an d buyer in digital content transactions on cyberspace market take place frequently because contracts were made without face-to-face discussion. The increase of illegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Digital content transaction authentication system would play an important role in creating sound digital content market. Especially, it would make big contribution to reducing the number of conflict between seller and buyer. In this context, the main objective of this study is to suggest operational model of digital content transaction authentication and to explain critical success factors in organizing digital content transaction authentication system.

Although the various crime involved numerous digital evidence, the digital evidence is hard to be acknowledged as a evidence to proof the crime fact in court. We propose the method of verification for the legal admissibility of digital evidence using digital forensics ontology. In order to verify the legal admissibility of digital evidence, we will extend the digital ontology by standard digital forensics process from Digital Forensics Technical Manual defined by KNPA and set up the relation properties and the rule of property constraint to process class in the digital forensics ontology. It is possible for proposed ontology to utilize to plan the criminal investigation and to educate the digital forensics.

South Korea is now recognized as a world leader in the field of digital government thanks to a president who had insight in the field of e-Government more than 20 years ago. Today, many countries around the world are establishing various strategies to cope with the great digital transformation beyond the industrial society and the information society. The Korean government is also establishing and promoting digital government policies to respond to such a global digital transformation. In South Korea, the digital platform government policy began in 2022. Therefore, it is an early stage of policy formation, and many details are not well known yet. Recently, the Korean government announced the vision, three goals, and five strategies for realizing a digital platform government. And specific digital platform government projects that can be implemented are selected. In order to successfully implement a digital platform government, the following three policies should be prioritized. First, the digital platform government should be approached from the perspective of total government innovation, not industry revival. Second, the political perspective should be excluded from ICT policy. Third, the vision and strategy of the digital platform government should be established and clearly presented to the public. And based on this, strong governance should be formed and strongly promoted centered on the leadership of the president.
