This study explores the possibility of maximizing locality through synergy between local terrestrial broadcasters and cable local channels. To this end, it examines the significance of the concept of locality in the changing environment represented by the 4th Industrial Revolution. It also analyzes the existing situation of broadcasting locality and the terrain of existing studies concerning cable local channels. Based on the reviews, the study searches for the connection points between local terrestrial and cable channels, which are still heterogeneous operators. The difference in the size of broadcast region and the programming time constitutes the optimum condition. As a result of this, the study discusses the issue of appropriateness and feasibility of bundling the local terrestrial and pay-TV channels in the same legal system. By doing so, it reveals the biggest obstacle in institutionalizing the cable channel into the public category is the emotional rejection towards cable TV. In order to overcome this problem, the study suggests to abolish both the current policy guideline characterized as the same service, same regulation principle and the abolition of local business right of cable TV. It also proposes to allow news commentary function of cable local channels and strengthen cable TV's own capabilities.

This study critically reviews the justifications for the restriction of cable local channel's news commentary function in terms of the fundamental principle of journalism. By doing so, it tries to find some problems and ways to solve them. Broadcasting Law and Korea Communications Commission's Rule inhibiting the news commentary of cable local channel on specific issues conflict with the basis of journalism which is particularly represented in Broadcasting Law. The law and rule tend to solidify public opinion for vested rights of local worthies. In addition, they are likely to degenerate cable local channel to the tools for promoting local government. Therefore, this article proposes the revision of the law and rule towards permitting the news commentary of cable local channel. At the same time, it suggests a new broadcasting policy for inducing cable local channel to increase manpower resources and production investment.

Local cable channels has been contributing to settlement of grass root democracy and local business facilitation in decentralization era compared to other broadcasting media, and duly performs its role as local-tied media and produces local closeness type programs. But this is the time of need for change of perception by the producers, business entrepreneurs and relevant organizations on various production environment following process of conversion to digital cable TV. For successful settlement of local digital cable channels, this study has forecasted change on broadcasting production and organization following conversion of digital cable TV through the in-depth interview with people who produce and organize actual programs, and factors that interfere with digital cable TV conversion. Furthermore, the study learned plans to establish role and function of local cable channel as new close media to realize local value.

This study analyzed the trends of broadcaster licensing policy during 1990-2001 in Korea. It is to seek the answers about how the examination standards and procedures applied to broadcaster licensing has been changed for the last decade. For the purpose this study inquired six cases such as private broadcasting licence (1990 October), cable TV program provider licences(1993 July), cable TV system operator licences(1994 January), private local broadcaster licences(1994 July), satellite broadcaster licence(2000 December) and cable TV home shopping channel licences(2001 March). It examined the degree of specification and measurement of the standards based upon the government white paper; average points per item, average points per quantitative item, and average points per qualitative item etc. The government hadn't opened the standards and procedures how it licensed broadcasters until 1990 and the uncertain attitude brought distrust on the government broadcasting policy. The first white paper about broadcaster licensing was made in 1994 after cable TV broadcaster licensing was finished. The results indicated that Korean broadcasting licensing policy rapidly developed in the dimension of transparency from 'a secret room policy' to 'a sunshine policy' for the last decade. But it still needs improvement in the dimension of fairness of examination. Now one of the main distrust is the ratio that the one of qualitative examination standards are much more than the qualitative one.

In the age of media convergence the influx of foreign TV content is quickly influencing the landscape of Korean media. The objective of this research is to analyze and explore the localization and Koreanization of Master Chef USA into Master Chef Korea and how its successful adaptation, transformation, and localization was made possible. The study pays close attention to TV personalities' relationships, behaviors and communication skills along with the choice of food ingredients and themes in the 2014 episodes for both Master Chef USA and Master Chef Korea. Furthermore, the research seeks to challenge the widely spread belief that localization of foreign TV content serves the public interest. Rather it seeks to articulate that depending on the media environment, private entities are becoming the benefactors of foreign TV content adaptations.

최근 광대역 서비스에 대한 소비자들의 욕구가 차츰 증가하고 있고 대상콘텐츠도 데이터와 음성 및 비디오까지 포함된 멀티미디어 서비스로 변화함에 따라, 통신서비스 제공업체들은 이에 대한 해결책을 찾는 것이 지상과제가 되었다. xDSL, 케이블 모뎀, 광랜 등 엑세스 네트워크가 잘 발달되어 있는 국내에서도 멀티미디어 서비스의 최종 수신 장치가 될 TV, PC, 오디오 기기 및 전화기 등에까지 네트워크를 연결하기 위해서는 댁내에서 또 다른 홈 네트워크를 구성해야 하는 상황이다. 이러한 홈 네트워크를 가능하게 하는 기술로는 홈 RF, 무선랜, 블루투스 등 무선 홈 네트워크 기술과 IEEE1394, 이더넷, 홈 PNA, 전력선통신과 같은 유선 홈 네트워크 기술로 나눌 수 있다. 무선 홈 네트워르 기술의 경우, 댁내에서의 반사와 감쇄 등의 영향에 의한 음영지역이 존재하는 단점이 있고 또 RF단을 구현해야 하므로 시스템 가격이 올라가게 된다. IEEE1394, 이더넷, 홈 PNA 같은 유선 홈 네트워크기술의 경우에는 댁내 통신을 위해 새로운 선을 포설해야 하는데 이를 위해서는 막대한 시설 투자비가 들어가게 된다. 이 막대한 투자비는 홈 네트워크 구축에 많은 시간이 걸리게 하는 요인이 될 뿐만 아니라, 일반 사용자들이 서비스를 이용하기에는 가격적으로 부담스럽게 된다. 전력선통신 (PLC: Power Line Communication) 은 전기를 공급하는 전력선에 흐르고 있는 상용주파수 50/60Hz의 저주파 전력신호에 고주파 신호를 활용하여 데이터를 실어 나르는 통신기술이다. 집안 곳곳 이미 포설되어 있는 전력선이 이미 하나의 네트워크를 구성하고 있기 때문에 번거롭고 값비싼 추가 배선작업 없이 바로 네트워킹이 가능하다. 이와 같은 이유로 고속 PLC는 설치 용이성, 접근성, 속도 및 비용부분 등에서 경쟁기술에 비하여 여러 장점을 가지고 있다. 젤라인은 국내 전력선통신 표준을 만족하는 24Mbps 고속 전력선통신 칩을 기반으로 다양한 전력선 채널환경 하에서 최적의 통신을 보장하는 전력선 통신시스템을 제공하고 있으며, 이를 소개하고자 한다.

The direct and indirect damages caused by fires in underground utility tunnels have a great impact on society as a whole, so efforts are needed to prevent and manage them in advance. To this end, research is ongoing to prevent disasters such as fire flooding by applying digital twin technology to underground utility tunnels. A network is required to transmit the sensed signals from each sensor to the platform. In essence, it is necessary to analyze the application of wireless networks in the underground utility tunnel environments because the tunnel lacks the reception range of external wireless communication systems. Within the underground utility tunnels, electromagnetic interference caused by transmission and distribution cables, and diffuse reflection of signals from internal structures, obstacles, and metallic pipes such as water pipes can cause distortion or size reduction of wireless signals. To ensure real-time connectivity for remote surveillance and monitoring tasks through sensing, it is necessary to measure and analyze the wireless coverage in underground utility tunnels. Therefore, in order to build a wireless network environment in the underground utility tunnels. this study minimized the shaded area and measured the actual cavity environment so that there is no problem in connecting to the wireless environment inside the underground utility tunnels. We analyzed the data transmission rate, signal strength, and signal-to-noise ratio for each section of the terrain of the underground utility tunnels. The obtained results provide an appropriate wireless planning approach for installing wireless networks in underground utility tunnels.
