방송의 디지털화에 따른 비장애인 대비 소외 계층의 정보 접근성의 부족은 소외 계층에 대한 정보 격차를 심화시킬 수 있다. 이에 캐릭터 수화 방송, 자막 방송 등 장애인을 위한 방송 서비스의 양적, 질적 개선에 관한 연구가 진행되고 있다. 자막 방송 서비스의 경우, 관련 법령에 따라 서비스를 실시하고 있으며 지상파 UHD 방송의 경우에도 본 방송을 시작한 이래 폐쇄 자막 서비스 시스템을 구축하여 서비스를 제공하고 있다. 이러한 기존 자막 서비스는 텍스트 형태의 단조로운 내용 전달 방식이어서 다양한 스타일로 풍부하게 내용을 전달하는 것에 대한 요구가 있다. 이에 본 논문에서는 지상파 UHD 방송을 대상으로 개선된 형태의 자막 서비스인 감성자막 서비스를 소개하고 이를 위한 감성 자막 편집기 기술 개발에 대하여 다룬다. 감성자막 서비스는 화자의 감정 정보를 자막 메타데이터에 추가적으로 제공하여, 감정에 따라 다양한 이모티콘이나 다른 종류의 폰트 스타일로 자막 서비스가 가능하게 하는 서비스이다. 감성자막 편집기는 이러한 감성 자막 메타데이터를 추가, 편집하고 감성자막 파일로 생성하기 위한 시스템으로, 지상파 UHD 송출 시스템 및 폐쇄 자막 표준을 고려하여 개발하였다.

Previous research on smartphone has been focused on personal performance, accessibility, and information gaps in information system quality. In order to analyze the relationship between the use of smartphone information and personal characteristics, this study conducted a survey of 300 tourists at Jeju Airport, by using three variables of self-efficacy, 'impulsiveness and demographic variables (age, sex, education level, etc.) of smartphone use with personal characteristics. In conclusion, self-efficacy and impulsiveness seem to be positively related to the use of smartphone because it seems to be a living environment in which the desired information can be acquired within a desired time. In addition, there seems to be a difference between a mobile native environment in which online and offline boundaries are always connected and an environment in which 40 to 50 digital literacies are connected. This can be interpreted as a result of additional analysis.

The rapid innovation of information and communication technology and its sharp falling prices have brought about the expansion of the Internet, integrating the world as one space under converged space and time. This rapid expansion of the Internet and its application in the economy have spurred the emergence of the digital economy. The Internet has influenced strongly on the changes of not only economic activities but also political, social and cultural activities. In this context, a rapidly increasing Internet expansion renders the rhetoric about the death of distance and about the meaningless of geographical place. However, the development and expansion of Internet induces a growing digital divide among nations and also a spatial inequality in a nation as the supply of the Internet has concentrated towards demand-affluent large cities. A large gap of digital access has been occurred between high income and low income countries according to a measurement of the international digital access index. In a national level, the Internet backbone has been built around large cities which favor a large amount of the Internet demand, and the affordable accessibility of these cities for the Internet services has influenced strongly on the agglomeration of Internet related industries, further inducing the construction and investment of the Internet backbone into large cities as cumulative causation effects. As a result, the expansion of the Internet affects immensely on the changes of spatial structure in a nation resulting in the new spatial phenomena such as centralization, concentration and splintering in the digitalized space-economy.

This study aimed to understand the effectiveness of teachers' backgrounds and digital textbook training experiences on digital competency, understanding of the digital textbook, perception of the digital textbook effectiveness and attitude toward the digital textbook. A total of 101 valid elementary, middle and high school teachers participated in the survey and the data were analyzed using the SPSS statistical package. As a result, male teachers showed higher digital competency than female teachers. Also, teachers who experienced with digital textbook training understood more about the digital textbook. It was suggested that a newly structured professional development program for the digital textbook considering teachers' personal backgrounds should be developed.

This study was designed to analyze the relationship among the motivations for the use of digital devices, attitudes toward the use of digital devices and performance resulting from the use of digital devices in middle-aged and elderly groups by using a path analysis. For an empirical analysis, the 2018 Survey on the Digital Divide by the National Information Society Agency was referenced, analyzing the data of 1,664 people, selected through listwise deletion from total 2,303 people aged 55 or over. A close examination of how measuring variables reflect potential variables (motivations for, attitudes toward and performance resulting from the use of digital devices) showed a significance of 0.001, which suggests that each individual measuring variable does reflect the potential variables. Evaluation of the pathway factors of the structural model from the motivations for the use of digital devices to the attitudes toward the use of digital devices (β=0.847) and from the attitudes toward the use of digital devices to the performance resulting from the use of digital devices (β= 0.745) revealed significant statistical effects. The results of this study suggest that the motivations for the use of digital devices does not directly enhance the digital device use performance, but that it can improve the attitudes toward the use of digital devices, which can in turn increase the performance resulting from the use of digital devices. The analysis holds significance that it has presented practical and policy implications.

FPD(Flat Panel Display) 시장은 디지털 기술의 발전으로 급속하게 성장하고 있으며, 이는 TV 시장에서도 마찬가지이다. 많은 전문가들은 LCD(Liquid Crystal Display)와 PDP(Plasma Display Panel)의 기술적 차이로 인해 LCD는 소형 크기의 TV에 적합하고, PDP는 대형 TV에 적합할 것이라 예상하고, 이에 따라 FPD TV 시장에 적용되는 기술이 목표시장(target market)에 따라 양분할 것으로 전망하였다. 그러나 LCD 생산기술상의 예상치 못한 급속한 진전은 PDP가 목표로 하는 대화면 TV 시장에서 LCD가 독자적인 틈새시장을 형성하고 이를 점차 확대할 수 있도록 하였다. 이러한 시장 전개 양상은 LCD와 PDP의 경쟁을 심화시키고, 현재 앞에서 전망한 바와 같은 현상은 발견되지 않고 있으며, 오히려 대화면 TV 시장에서조차 LCD가 우위에 있음을 보여주는 사례가 많다. 본 연구에서는 LCD가 PDP와의 기술적 격차를 줄이고, 결과적으로 LCD와 PDP간 경계를 무너뜨린 보다 근원적인 원인을 분석한다. 특히 이러한 잠재적 메커니즘을 시스템 다이나믹스 방법론을 도입하여 분석한다. 특히 PDP에 대하여 점진적으로 LCD가 우위를 확보하게 되는 피드백 루프들을 밝혀 내고자 한다. 그리고 이러한 피드백 루프 중에서 가장 효과가 큰 메커니즘을 찾아낸다.

The purpose of this study is to suggest action directions for preventing social isolation and improving life satisfaction of the elderly by verifying the mediating effect of social capital in the relationship between the elderly's digital information self-efficacy and their life satisfaction. For this purpose, the 2022 digital information gap survey data were used to analyze the relationship between digital information self-efficacy, social capital, and the elderly's life satisfaction using SPSS 26.0 and AMOS 24.0. As a result, first, the elderly's digital information self-efficacy was found to have a positive (+) effect on life satisfaction. Second, the elderly's digital information self-efficacy was found to have a positive (+) effect on social capital. Third, the social capital of the elderly was found to have a positive effect on life satisfaction. Fourth, the social capital of the elderly was found to have an indirect mediating effect in the relationship between digital information self-efficacy and life satisfaction. Based on this, practical and policy measures were presented to revitalize digital information education that older people can apply in real life, develop a digital platform for forming online-based social capital, communities suited to the digital information capabilities of older people, and revitalize information groups.
