It is widely known that farmers and fishermen group is typically alienated from information. In this regards, it has become a national policy to help them get benefits from using PC. Therefore, this study investigates the effects of PC competence on their life satisfaction by using the 2017 report on the digital divide. Especially, we are focused on analyzing mediating role of Internet service usage. Empirical analysis with public database showed that PC competence has a positive effect on life satisfaction. Internet service usage also revealed a mediating role between PC competence and Internet service usage. Implication for policy makers is that government needs to exercise PC competence level of farmers and fishermen, and their ability to utilize Internet service for the sake of improving their life satisfaction level. We recommend future research with hierarchical linear model to measure the effect of regional differences.

In recent years, activities have become more important in political activities and participation in policies. Therefore, the level of digital informatization can affect the participation in policy in the online environment. In this study, we examined how the policy activities of the disabled have a relationship with the informatization level. To this end, we analyzed the relationship between the level of digital informatization and the level of satisfaction with policy activities based on the results of the digital divide survey of 2017. The results of this study are as follows: First, it shows that the disabled people have a positive relationship with the digital access and policy activity satisfaction levels such as the possession of wired / wireless information devices and Internet accessibility. Second, it is found that digital information capacity level and income level such as PC utilization ability and mobile digital device utilization ability have a positive (+) relationship. Third, as the level of digital information utilization such as wired and mobile Internet usage increased, the level of satisfaction with policy activities also increased positively. This suggests that the government needs various information policy to increase the level of digital informatization of the disabled.

Our society is evolving into an aging society. The purpose of this study is to investigate how digital informatization capacity of elderly people, one of the so - called information - neglected people, affects social activities. To this end, we analyzed the relationship between digital informatization level and social activity satisfaction level of old elderly people based on the results of the digital information gap survey in 2017. As a result, it was found that there was a positive relationship between digital access and satisfaction level of social activities, such as whether elderly people have wired / wireless information devices and internet accessibility. Second, it was found that digital information capacity level such as PC usage ability and mobile digital device utilization ability had a positive (+) relationship with only social activities. Third, the level of satisfaction with social activities increased as the level of digital information utilization increased, such as whether they were using wired and mobile Internet. This suggests that the government needs a policy to resolve various information gaps that can enhance the level of digital informatization of elderly people.

The definition of digital poverty of multicultural families has not been changed since it was used at the first digital divide survey in 2012. The objective of this study is to reexamine and redefine digital poverty targets of digital divide survey for multicultural families. The results suggest to reexamine multicultural families rather than limiting to Immigrant women for digital poverty. The results were as follows. First, the current survey has been limited to the migrant women for information gap survey of married migrants. But, It is expected to increase immigrant men in the future. It should include migrant men in the marginalized target in terms of preparation for a multicultural society. Second, the current survey has been limited to the migrant women for information gap survey. But, It is expected to increase children of multicultural families. This information gap is likely to be linked to differences in education or future economic disparities for children of multicultural families. It should include children of multicultural families in the marginalized target in digital divide survey.

In this paper, we study on making a use of value-added services using DTV closed caption data. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be provided by an enforcing law in all broadcasting services in April 2008. Here, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file using the extracted caption data and time information. In addition, we present the segmentation method of broadcasting content using caption file. Experimental results show that implemented S/W tool provides the feasibility of the proposed methods and the usability of closed caption for a variety of data application service.

In modern society, efforts to improve quality of life and happiness are emphasized compared to the past when economic growth was emphasized. The government has been implementing various policies to realize the happiness of the people through culture. The purpose of this study is to investigate the effect of Cultural Arts on the improvement of the happiness index of Seoul citizens by dividing them into demand (enjoyment) and supply side by setting Cultural Arts as independent variable, unlike existing limited surveys or literature surveys, under the control of change, the temporal range was set for more than 10 years and then analyzed quantitatively by panel analysis. The results showed that the demand for cultural arts affects positively on the improvement of happiness index of Seoul citizens, but the supply of cultural arts had a meaningless effect. In order to improve the happiness index of the citizens of Seoul through supply, it is necessary to supplement the existing space and to promote cultural demand through differentiated cultural arts programs aimed at diverse classes but also the policy implication that cultural indifference groups and active participation of cultural underprivileged groups should be increased.
