This study is a sustainability study of K-Music beyond K-Pop through New Media. New media literally means 'new media'. When TV, classified as legacy media, first appeared in the world, it was an innovative new media platform. Of course, it is considered the most traditional legacy media. However, the definition of new media inevitably changes with the times. Most of the media called new media today are based on online and mobile. This thesis focuses on popular music including crossover traditional music genre. And we define popular music exported abroad as K-pop, and propose the possibility of globalization of Korean music using K-pop users and new media, a metaverse based K-pop audition platform, as consumers and suppliers in the global market. Hallyu, the studying of K-Pop through the study of attitudes and economic effects of K-pop, such as reactions to the spread of K-pop and the reactions of fans who like K-pop, are constantly being discussed in various ways. But there has been no case of cultural technology research that linked the sustainability of Gugak as the Korean music through new media to the K-pop business platform. As the overflowing data pours out in the virtual space as an act that gives the meaning of existence, the online is able to become an open market that provides reliable information all over the world. Therefore we would like to propose on the sustainability of Korean music through the 'Korean Traditional Music Broadcasting Metaverse Audition' beyond the K-pop business model as the K-Music content in the cultural technology era.

웹은 이미 인터넷 사용에 있어 가장 중요하고, 자주 이용하는 서비스로 자리 잡고 있으며, 이에 대한 여러 활용 방안에 대해서도 많은 연구가 진행되었다. 그럼에도 불구하고 웹을 이용한 메시지 전달이나 광고 등은 서비스를 제공하는 포털에 의해서 진행되고 있고, 해당 포털에 접속하지 않은 사용자에게 원하는 메시지를 전달하기가 어려운 것이 현실이다. 이미 긴급 재난 공지 등은 각 포털의 공지사항 등을 이용하여 전달하고자 하는 시스템을 구축하고 있지만 이는 결국 해당 포털에 접속해야만 메시지를 볼 수 있으며. 각 포털에 메시지를 전파하고 협조를 얻어야 하는 등의 문제가 있다. 또한 지역적, 국지적으로 발생하는 사안이나 긴급을 요하는 메시지의 경우 이러한 방식이 맞지 않고, TV, 방송 등의 직접적인 수단을 통해서만 메시지를 전달할 수밖에 없으며, 대부분의 많은 메시지가 이런 식으로만 전달하기엔 적합하지 않은 현실에 비추어 볼 때 그다지 효율적이라 볼 수 없다. 이에 7계층의 컨텐츠 스위칭 기법에서 사용되는 방식을 이용하여 네트워크의 중간에서 직접 사용자별 혹은 목적지 별 메시지를 사용자가 접속하려는 사이트나 해당 컨텐츠의 저작권과 관계없이 메시지를 전달하는 방안을 제안하고자 한다.

With major sports events such as FIFA World Cup and The Olympic Games coming up, UHDTV technology has been given a major push by broadcasters, test and measurement (T&M), and consumer electronics (TV and set-top box) manufacturers. The increase in picture resolution ($3840{\times}2160$) for 4K and ($7680{\times}4320$) for 8K compared to current HDTV ($1920{\times}1080$), as well as the need to deliver these services in higher frame rates (50/60 up to 100/120fps) translate to a big challenge in UHDTV content delivery to households over terrestrial transmission due to higher data rates. DVB-T2 has been favored by many countries across the world as it is proven to give the best spectral efficiency for terrestrial broadcasting. On the other hand MPEG-4 appears to be the bottleneck for UHDTV since a much higher data rate is needed to deliver such services. Therefore HEVC becomes mandatory for UHDTV delivery over DVB-T2. In this paper, we will give an overview about a complete end-to-end solution for UHDTV delivery over DVB-T2 based on a realistic SFN scenario in Seoul metropolitan area.

Radio waves including GPS signals, various TV communications, and radio broadcasting can be disturbed by a strong solar storm, which may occur due to solar flares and produce an ionospheric delay anomaly in the ionosphere according to the change of total electron content. Electron density irregularities can cause deep signal fading, frequently known as ionospheric scintillation, which can result in the positioning error using GPS signal. This paper proposes a detection algorithm for the ionosphere delay anomaly during a solar storm by using multi-reference stations. Different TEC grid which has irregular electron density was applied above one reference station. Then the ionospheric delay in zenith direction applied different TEC will show comparatively large ionospheric zenith delay due to the electron irregularity. The ionospheric slant delay applied an elevation angle at reference station was analyzed to detect the ionospheric delay anomaly that can result in positioning error. A simulation test was implemented and a proposed detection algorithm using data logged by four reference stations was applied to detect the ionospheric delay anomaly compared to a criterion.

Along side with the rapid growth of local governments' advertising bills, there are few studies focused on the effectiveness of these ads. Especially one of the media being used by the local governments is the Korea Express Train (KTX), where they advertise in the train coaches' KTX video monitor. Unfortunately the ads in KTX are exposed without audio mostly. The current study, therefore, probed on the effectiveness of these ads. This study utilized transportation theory and content analysis methodology to give insight to its discourse. We established two analysis units (camera and subtitles), and then analyzed 107 local government ads. From the camera analysis, it is observed that local governments' festival and tour promotion ads more often employ dynamic angles such as drone shot and long shot. Also, from subtitles usage analysis, it is observed that many of the ads make use of large size titles and subtitles which could prevent viewers seeing visual shots. In the special case audio-less KTX ads, this study recommends emphasis on subtitles which will enhance the ad effectiveness of the ad messages.

The emphasis in environmental education for children should be on awareness, appreciation, and sensory experiences. By offering children opportunities to experience the elements of nature that surround them, teachers elevate children's comfort level and familiarity with the natural world. But many children have little contact with nature, because of urban living, hurried schedules, TV's attraction, and the low value most schools place on outdoor activities. So, teachers have to expand the real out-of-door experiences into the classroom by sharing and making accessible books focusing on nature and the natural environment. Namely, quality children's literature is an excellent vehicle for extending a particular experience or introducing new ones. Building on outdoor experiences through stories encourages children to explore more deeply what they have observed and experienced-concepts are reinforced, new knowledge gained, vicarious experiences provided. There are three-fold classification of environmentalism, especially environmental ethics, and three-aspects of the history in children's literature. The analytical results of this study are as follow. The environmental ideology in elementary Korean textbooks varies from 'egocentrism-didacticism' to 'ecocentrism-fantasy'. This finding has implication for selecting children's books and teaching environmental contents in elementary school. Therefore teachers and parents need to get ready to receive ecocriticism.
