This study focuses on the management of the news production system in broadcasting companies. This paper concentrates on the process of data registration and metadata management in order to examine whether the currently produced news can have value as a 'public record' in the long term, and whether reliable and accurate information is preserved. In addition, the user experience in the current system is analyzed through in-depth interviews with Ingest Managers, Editors, and Archive Managers, who are closely related to metadata creation compared to other members of the its News Department. Finally, a sustainable metadata quality management method is sought to increase the value of news footage as a 'public record'. In this study, these points can be found out: the metadata of the news agency footage is input manually according to the user's will or working style, that is, the user-friendly metadata input system is insufficient. Accordingly, it can be seen that the quality of the metadata of the news video continues to deteriorate. As an alternative to overcome this, it is found that work flow improvement, system improvement, classification system and metadata improvement plan, etc. are definitely necessary in the short and long term.

Sampling inspection methods for quality control have been proposed a lot in the industry. However, the sampling inspection method for reliability, which is a quality over time, has been relatively less presented, and there are not many literatures that are clearly summarized. Therefore, this paper focuses on the reliability conformity test to verify that the reliability evaluation scale value of the target is satisfied during the reliability test. To this end, first, we look at the conditions that both consumers and producers can satisfy in terms of the OC curve and find out what sampling methods satisfy the desired level of producer risk and consumer risk. Next, two methods of the reliability sampling methods such as attribute and variable reliability sampling methods are examined. Specifically, the attribute reliability sampling method is a form of sampling plan where n samples are tested for a certain period of T hours and the lot is accepted if the number of failures is less than or equal to a certain number c. On the other hand, the variable reliability sampling method is a form of sampling plan where the lot is accepted if the reliability evaluation scale such as MTBF satisfies a certain standard. Both sampling plans may also use inspection tables.

실감 미디어(Realistic Media)란 사용자 만족을 위해 몰입감과 현장감을 극대화 할 수 있도록 현장의 모든 감각의 정보를 전달하는 매체를 의미하며 실감미디어 기술은 고품질의 시각, 청각 정보는 물론 촉감 등 다감각 정보의 생성, 처리, 저장, 변환, 전송, 재편등에 관한 기술로 정의할 수 있다. 무선 네트워크 기술의 발전과 스마트폰 시장의 급격한 성장에 따라 다양한 실감미디어 서비스들이 출현하고 서비스되고 있어 실감미디어 산업은 국내 뿐만 아니라 세계적으로 급격하게 성장하고 있다. 우리 정부에서는 미국, 일본, 유럽 등의 기술을 따라잡고 독자적인 기술력을 마련하기 위하여 '기가코리아(2012)' 사업을 필두로 다양한 정책 사업을 진행 중에 있는대 현 시점에서는 해외 기술에 비하여 2-3년의 격차가 존재하고 있으나 무선 인프라, 스마트폰 기반의 콘텐츠 시장 형성 등 기반 인프라가 우수하고 방송, 교육, 광고, 공공 서비스 등 타 산업분야와 융복합 등 기반 기술 확보부분에서 기술 선점 가능성이 남아있으며 다양한 분야로 사업 확대가 용이하여 시장성이 높아 차세대 전략 산업으로 주목받고 있다. 최근 미디어 서비스에 대한 사용자의 요구사항 변화는 단순 시청의 단계를 넘어 미디어 미디어 서비스의 부가 정보를 얻고자 하며 직접 미디어 서비스에 참여하기를 원한다. 특히 실감미디어 분야에서 2D 미디어에서도 3D 입체 미디어화가 급속도로 진행되고 있으며 3D 입체 미디어를 기반으로 실감체험을 가능하게 하는 4D미디어를 선호한다. 대표적인 사례가 아바타 4D 영화의 흥행이라고 볼 수 있다. 앞으로도 4D 미디어를 소화해낸 사용자는 오감과 감성에 기반한 미디어 서비스를 지속적으로 요구할 것이며 이러한 요구에 맞추어 실감미디어 산업의 빠른 변화가 진행되고 있다. 이미 영화 산업은 3D 산업으로 진입해 있으며 4D 산업으로 급속히 변모중에 있고 스마트 시장의 등장에따라 스마트 기기 및 인프라를 기반으로 실감미디어를 제공하는 서비스 시장 역시 급속도로 성장하고 있다. 이에 본고에서는 실감미디어 산업의 시장규모와 앞으로 어떻게 발전할 것인지를 알아보며, 어떠한 형태의 실감미디어 콘텐츠 서비스가 존재하고 있는지 알아보고자 한다. 또한 국내외에서 적용되는 실제 사례를 분석하고, 마지막으로 실감미디어 콘텐츠 산업의 경쟁력 강화를 위한 시사점을 제시하고자 한다.

In this paper, we designed, constructed and evaluated the system for the FTTH suited to a residence and apartment using CWDM-PON techniques. These systems have capacity to service at 100Mbps rate to 384 users in the same breath. Also, the services include the internet, CATV, IPTV and wireless LAN. In the case of ire network, the data could be transmitted by UTP cable and optical fiber and case of wireless one, the data transmitted using WLAN. The distance between the cental office and the user is 20km and the data rate is 100Mbps maximum. Of course, the optical network used just one fiber optical core. For the basic material, we obtained the characteristics of optical transceiver module, Mux/Demux and transmission qualities depends on the environment.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.

Terrestrial digital multimedia broadcasting (TDMB) is a method of bringing multimedia images, radio, internet, and television to portable devices through terrestrial digital radio transmissions. TDMB related educations being carried out in colleges are focusing on developing firmware which enables users to choose a wanted service. TDMB transmission frame is made up of synchronization channel (SC), fast information channel (FIC), and main service channel (MSC). Services such as video, audio and date are transmitted in the form of subchannel in the MSC. FIC carries information related to each services and subchannels. This paper presents a TDMB frame analysis simulator for analyzing and displaying FIC data on PC. TDMB frame analysis simulator contains functions such as controlling TDMB receiver through USB, establishing the frequency, bringing FIC to PC, displaying ensemble ID and levels, and displaying informations related to services and subchannels. In addition to that, this simulator has a function of being able to store FIC date and subchannel data. This simulator being developed with C++ is expected to be used to view those data visually so that it helps students to understand the TDMB system better and bring about the educational motivation.

The purpose of this study is to analyze news content consumption of news consumers in which a few media conglomerates control news consumption market caused by deregulation of media policy and development of Internet communication technology. In doing so, this study analyzes the consumption realities of news consumers in the new news consumption market generated by new media and mobile communication technologies, and the effects how the new news consumption market influences on news consumption pattern of audiences. After surveyed 229 news consumers, this study founded that news consumers use NAVER(news portal site) mainly while consuming news contents, specifically younger generation tends to use NAVER heavily. Furthermore, it is founded that news consumers chose news outlets for consuming news contents not by the quality of news contents and the function of the news outlets but by their own convenience.
