As social problems related to the digital divide are increasing, the elderly are facing various problems as an information alienated group. In particular, there is a need to strengthen the ability to critically understand and accept information. In this study, using the 2020 media panel survey, the effects of digital literacy in the elderly on critical thinking disposition of information were analyzed, focusing on the moderating effect of need for cognition. As a results of the analysis, it was confirmed that the operational and the information skill had a positive effect on the critical thinking disposition of information. Also, as a result of analyzing the moderating effect of NFC(Need for Cognition), it was found that NFC strengthens the influence of operational skill and reduces the influence of information skill. This suggests that the digital literacy education for the elderly needs to change from strengthening accessibility to improving information judgment.

The recent advances in multimedia signal coding and transmission technologies allow lots of users to watch videos on small LCD displays. In this paper, we briefly describe an intelligent display technique to provide small-display-viewers with comfortable experiences, and study the minimum image size tolerated and utility of displaying region of interest (ROI) only when needed. The study, with 111 participants, examines minimum image size to ensure viewers pleasant viewing experiences, and evaluates the degree of satisfaction when they are viewed with region of interest (ROI) only. The experimental results show that the ROI display enhances the viewers' satisfaction when the image size becomes less than $320{\times}240$, and thus it is useful to provide the intelligent display, if necessary, which can extract and display ROI only.

This study explored the moderating effects of security ability on the influence of privacy concerns on internet activity using Korea media panel survey data. To this end, we applied between-subjects factorial design between 2 (privacy concern high / low) × 2 (security ability high / low) groups and compared five types of internet activity among four groups by variance analysis. As a result, privacy concerns have a main effect on internet activity, and security ability have a moderating role in this relationship. Despite the privacy concerns, people do their internet activities in order to enjoy the benefit from the internet. This study have academic implication in that it focus on the issue of privacy paradox in terms of the type of internet activity. In addition, practical implications are that, in order to activate online activities of individuals in an internet-connected society, efforts for enhancing their security abilities are necessary.

This study aims to empirically investigate how users' online engagement behaviors predict their uses of paid contents. To this end, the data from the 2016 Korean Media Panel Survey, which has been conducted annually by the Korea Information Society Development Institute(KISDI), were analyzed. Major findings(N=8.313) were as follows. First, the active type of online engagement(e.g., posting, commenting), which contributes to direct creation of online contents, was the most powerful predictor to explain the DV. On the other hand, relatively passive actions of user engagement(e.g., sharing, endorsing, voting) turned out to have no significant effects on the uses of paid contents, just as personality traits and online privacy concerns did. Based on these results, it is recommended that online contents or platform service providers should try to establish clearly-targeted marketing strategies, after thoroughly collecting and analyzing the data of users' various online behaviors.

In this study, we explored consumers' the privacy attitudes and Internet activities on the expectations of the fourth industrial revolution. Furthermore, we examined the moderating effect of Internet activities between the privacy attitudes and the expectations of the fourth industrial revolution. Research data are 2018 Korea media panel survey provided by Korea Information Society Development Institute. As a result, concerns about privacy were negative on the expectations of the fourth industrial revolution. Consumer's internet activities had a positive effect on the expectations of the fourth industrial revolution. Concerns about privacy have a negative effect on the expectations of the fourth industrial revolution, but active internet activities have mitigated it or turned it into a positive. This study will contribute as basic data for more active responses in the economic structure facing the 4th industrial revolution.

As digital content services, especially OTT(over-the-top) video services, diffuse rapidly, so do smartTVs. Based on the indirect network effect theory and the complementarity theory, this study explores the relationship between digital content services and smartTV. Using the Media panel dataset, this study analyzes how the usage of digital content service (OTT usage, OTT usage volume, the usage of various OTT service types, and online game/music/education/news service) affects smartTV usage. This study shows that OTT usage and its usage volume is positively associated with smartTV usage, and that the usage of various OTT service types is positively associated with smartTV usage compared with non-OTT users. As for online content services, the usage of online education service is positively associated with smartTV usage while the usage of online news service is associated negatively. These results support the indirect network effect theory and the complementarity theory.

This study is to verify the mediating effect of self-esteem on the effect of the elderly's smart device use on life satisfaction. To this end, secondary data analysis was conducted using the Korea Media Panel Survey conducted by the Information and Communication Policy Institute in 2021. The responses of 3,211 people in their 60s or older who are the subjects of this study were utilized. For analysis, descriptive statistics, correlation, and multiple regression analysis were performed using SPSS, and the Sobel test was conducted to verify mediating effects. As a result, smart device utilization averaged 2.13 points out of 5, indicating that the actual utilization level was less than half. The use of smart devices, an independent variable, had a positive effect on the dependent variable, life satisfaction. Self-esteem, which is a parameter, has been verified as a partial mediating effect in that smart device use affects life satisfaction. Based on the results of this study, various policy and practical measures were proposed to increase the smart device utilization rate of the elderly in Korea, improve self-esteem and life satisfaction, so that they can spend a happy old age.
