Our vision is to see the North and there is a large visual target that the two exchanges and cooperation and unity that put the main enemy of enemies in mind in need. North Korea is the main enemy was illegal invasion June 25, 1950 July 27, 1953 has continued after the armistice join the illegal provocations and cease fire violations so far. August 4, 2015, North Korea was operating by the power differential that operate on an all-out war and declared the initial state after the exhibition gave another provocative DMZ wood box mines. US-ROK military was in the process of real-time detection of the North Korean power operation and the results were broadcast live through the media. Looking at these military provocations on the threat of asymmetrical power of North Korea's military threat, we would like to present how to respond.

Due to rapid advance of wireless communication technology, demand on data services in mobile environment is gradually increasing. Caching at a mobile client could reduce bandwidth consumption and query response time, and yet a mobile client must maintain cache consistency. It could be efficient for the server to broadcast a periodic cache invalidation report for cache consistency in a cell. In case that long period of disconnection prevents a mobile client from checking validity of its cache based solely on the invalidation report received, the mobile client could request the server to check cache validity. In doing so, some schemes may be more efficient than others depending on the number of available channels and the mobile clients involved. In this paper, we propose new cache consistency schemes, effects, efficient especially (1) when channel capacity is enough to deal with the mobile clients involved or (2) when that is not the case, and evaluate their performance.

This study aims to analyse the process of digital switchover in the UK, which is regarded as one of the most successful cases in the world, and to examine efficient plans for the future digital switchover project in Korea through the UK's case. The digital switchover in the UK shows with no doubt the significance of integrated government policies, collaboration between relevant governmental organisations, and the public service broadcaster. Along with this, active and detailed Public Relations (PR) should take place, helping the citizens realise the efficiency of the phased switchover region by region and the measures to resolve the gaps between all social brackets. To sum up, the successful digital transfer is not only achieved by governmental policy and technological preparation from broadcasters, but also by voluntary citizen participation. Government officers and broadcast executives need to realise this and should focus on communicating with citizens.

Digital broadcast environment led to the emergence of UHDTV following HDTV. The demands for realistic images which are created with the use of UHDTV have been applied to various fields. Of various application methods, multiplanar imaging, which is used to display high definition image contents after multiple HD or UHD displays are connected with each other up and down, and left and right, is often applied to display images and the advertising market. Today, the firms that make high-definition multiplanar images mostly use their independently developed program. Therefore, it costs higher than other general works. For the reason, multiplanar image contents are mostly made in the way of enlarging HD images over 2 to 5 times. In this experiment, the software application widely known for UHDTV based multiplanar images is applied to test a method of implementing UHD panoramic realistic images without quality degradation.

Yaksun, a medicinal diet, has been traditionally prepared and applied (based on theories in oriental medicine) for the modulation of disease symptoms and signs. However, restaurants that serve and claim Yaksun mainly focus on stamina foods. A consistent definition of Yaksun has not been provided, which can confuse the public interpretation of Yaksun. The purpose of this study was to investigate the perception of Yaksun in Korean adults living in Seoul, Gyeonggi, and Chungbuk regions. Among the participants (M=55, F=168, 25y), only 10.4% understood the definition of Yaksun (mainly through the broadcast media). The frequency of Yaksun consumed when eating out was 2~3 times per month in 50.2% of participants. The main reason for choosing a Yaksun menu (46.3% of participants) when eating out was for health. The mean satisfaction score of Yaksun was $3.5{\pm}0.8$ on the five point Likert scale. Participants highly agreed ($3.8{\pm}0.8$) that Yaksun is composed of nutritious foods combined with oriental medicinal herbs for the treatment of disease, which was significantly higher in groups with learning experience on Yaksun (p<0.05). Interestingly, participants showed neutral to the description, that a diet without oriental medicinal herbs is not Yaksun ($3.1{\pm}1.0$), which was significantly different between genders (p<0.05). Men recognized more than women that Yaksun should be based on oriental medical theory (p<0.05) and should be prepared for the prevention or treatment of diseases (p<0.05). In conclusion, the concept and terminology of Yaksun need to be defined and publicized in modern diet.

This study analyzes the characteristics of mobile live streaming service, the illegal and harmful information characteristics of mobile live streaming service for the purpose of eradicating illegal and harmful broadcasting, and shows illegal and harmful broadcast on the mobile live streaming service and eradication plan. First, we reviewed the mobile live streaming service, illegal and harmful broadcasts through literature review, and secondly surveyed illegal and harmful broadcasts of mobile live streaming services and their awareness and countermeasures. As a result, it is confirmed that the mobile live streaming service is illegal, harmful broadcasting exposure frequency is high, illegal, and harmful broadcasting exposure is caused by characteristics of real time broadcasting rather than user's. In order to eradicate the illegal and mobile information about the mobile live streaming service, it is necessary to fix the illegal service and harmful broadcasting reporting system, but the government has confirmed the requirements for regulatory measures. From a microscopic point of view, it will be necessary to investigate the illegal use of mobile live streaming services and the eradication of harmful information.

The purpose of this study is to suggest the development of interactive services and technologies in the media industry. Through the analysis of domestic two-way broadcasting contents service, this study analyzed platform and services type according to service type of terrestrial broadcasting, SO operator and Telco. Also, by identifying the characteristics of interactive programs(open, interactive, personalized, stereoscopic), this study propose important convergence possibilities of the future providers and development plans through supporting technologies and services for each characteristic. In the case of terrestrial broadcasters, ARS, web sites and mobile apps were mostly provided in both directions, and SO and satellite broadcasting operators were found to provide diversity in interactive service operation using data domain. In the case of IPTV companies, most of them provide interactive services with additional video or information service through adjustment button or app, and cable TV operators had more adjustment data broadcasting than exclusive use data broadcasts. Therefore, domestic interactive broadcasting service type needs convergence type of revenue model needs and needs to be converted into new competitive interactive broadcasting program service environment.

Tunnels and subterranean roads, which are representative evacuation facilities for national or regional disasters, have radio relay broadcasting facilities for legal reasons and convenience reasons. However, this system is limited to radio broadcasting and it is impossible to effectively communicate disaster or emergency situations that occur locally due to broadcasting of national broadcasting without DMB broadcasting. In order to improve this, we construct a remote disaster broadcasting system at each regional disaster station and implement a system to transmit it to each tunnel using internet or LTE network. The system in the tunnel transmits the emergency broadcasting signal through the existing relay equipment through the modulator which decodes the SMS, the media file, the real time broadcasting or the image received by the digital signal and converts it into FM and DMB frequency. The method proposed and implemented in this study can be used to provide efficient information and remote field control in case of emergency in tunnel and underground roadway.

Objectives: Ongoing, proactive, planned, and patient-centered diabetes education is the cornerstone of care for all persons with diabetes. Thus, the aim of this study was to explore the information needs of type 2 diabetes mellitus patients receiving insulin treatment in North-East Ethiopia. Methods: The study was conducted from July 2019 to January 2020 using a qualitative enquiry (phenomenological approach) with purposive sampling. Face-to-face in-depth interviews were used to collect data until reaching theoretical saturation. The participants were type 2 diabetes patients receiving insulin treatment. They were identified from the diabetes patients' registration book at the diabetes clinic and interviewed at their appointment time, and were selected to include wide variations in terms of socio-demographic characteristics. Twenty-four participants (11 men and 13 women), with a median age of 57 years, were interviewed. The data were organized using QDA Miner Lite version 2.0.7 and analyzed thematically using narrative strategies. Results: Most participants had not heard of diabetes before their diagnosis. They had limited knowledge of diabetes, but ascribed different connotations for it in the local language (Amharic). The needs reflections of patients were categorized into diabetes education and participants' recommendations. Diabetes education was totally absent at hospitals, and patients received education primarily from the Ethiopian Diabetes Association and broadcast and digital media. Thus, the major concern of patients was the availability of diabetes education programs at health institutions. Conclusions: Patients' main concern was the absence of routine diabetes education, which necessitates urgent action to implement diabetes education programs, especially at health institutions.
