본 논문에서 구현한 MPEG-4 미디어 재생기는 네트워크를 통하여 스트리밍 서버에 메시지를 전송하고, 스트리밍 서버로부터 전송된 미디어 스트림을 처리하여 사용자의 화면에 보여주는 역할을 수행한다. 미디어 재생기는 서버에게 VCR(Play, Pause, Stop, Jump)이벤트를 전송하며, 리눅스 운영체제에서 동작한다. 본 논문에서 제안하는 미디어 재생기는 VCR 연산을 위한 RTSP(Real Time Streaming Protocol)를 지원하며 데이터의 실시간 전송을 위하여 RTP(Real-time Transport Protocol)／RTCP(real-time transport control protocol)를 지원한다. RTP/RTCP를 통하여 네트워크 QoS와 관련된 정보를 획득하며 그 정보에 따라서 데이터 전송율을 조절하고 RTCP를 이용하여 에러 패킷에 대한 재전송을 사용한다. 재전송시 미디어 재생기의 버퍼링 상태와 멀티미디어 데이터의 재생시간을 고려하여 멀티미디어 데이터의 끊김이 없도록 한다.

최근 보행자 행태를 반영한 미시적 시뮬레이션 분석이 가능하게 되었다. 차량 분석과 유사하게 보행자 행태 중 가장 빈번히 사용되는 것은 보행속도로 이는 횡단보도 보행자 녹색시간 산정과도 매우 밀접한 관계가 있다. 또한 보도의 밀도를 산정함에 있어서 보행자 속도는 중요한 역할을 담당한다. 이에 본 논문에서는 횡단보도의 보행자 속도를 실측하고, 이를 기반으로 미시적 시뮬레이션인 VISSIM의 주요 파라메타인 보행속도를 이용하여 역삼역 일대의 보행실태를 점검해 보았다. 분석에 사용된 보행속도 실측자료는 서울시 16개 횡단보도에서 조사되었으며, 연령별로 일반인(64세 이하)과 노인(65세 이상)을 구분하여 분석하였다.

This study selected the Marine Corps camp accident in 2013 as its subject and analyzed it in order to explore the relevance of media framing on discourse on the safety of outdoor experience activities. Data were collected from search sites provided by news coverage data from March 26, 2010 when the sinking of the South Korean Navy corvette Cheonan occurred in South Korea, which had seen a surge in Marine Corps experience camps, to July 21, 2013, a few days after the Marine Corps camp accident. Data about a total of 211 cases 138 cases before the Marine Corps camp accident, and 73 cases after the accident were inductively analyzed. According to the results, news coverages on the Marine Corps camp were largely divided into positive framing that glamorized outdoor experience activities before the accident and negative framing after the accident. To put it concretely, the framing before the accident tended to glamorize outdoor experience activity as the best educational program which helped the participants to enhance their patience and sense of independence through boot camp experience, thereby increasing their self-esteem and arousing their cooperative spirit as members of society. However, after the accident media framing tended to publicize insensitivity to safety. The media framing characterized by dualistic coverage is considered to be an obstacle to the spread of safety culture, which is required in South Korean society. Therefore, media need to maintain more cool-headed and objective attitudes when reporting news.

Recently, media's attention to tourism is enhanced, and the proportion of tourism related content is increasing. Hence, the present study performed a content analysis of the travel news stories in major Korean newspapers to figure out the current state of travel journalism. A rotation sampling method was employed, and 53 days in 2013 were selected. Main coding categories were type, theme, and writer of the news stories and the degree of promotional information in the news stories. Differences among newspapers and the degree of inclusion of the promotional information according to news types and themes were analyzed. Analyses revealed the differences among newspapers and the degree of inclusion of promotional information was different according to the news types and themes. On the basis of the findings, problems of the travel journalism were identified, and possible measures to solve the problems were discussed.

With rapidly changing multimedia environment, various artistic changes and digitalized up-to-date social infra, urban environment construction based on culture contents has been activated. The large image in front of urban building that is expressed as media-façade, increasing rapidly in a recent period, is not a new thing at all. In addition, IT technology molten in city space is testing the possibility of new media through the meeting with architecture. However, unlike its infra enlargement, the definition about media-façade is not clear so the system was constructed in a level of night lightscape or outdoor image advertisement. The purpose of this guideline is the regulation from the negative aspect rather than the possibility of various visual, artistic media expressions. Therefore, it could not show essential concept of media-façade. Moreover, most of companies or building owners focus on short-term profit and marketing effect rather than prepare various contents so they can not use constructed infra properly. After all, in many cases, they discolor the meaning of media-façade. This paper is a pilot study to grasp the current definition of media-façade to construct right guideline of media-façade. On the basis of this study, it will prepare academic definition of media-façade and construct the guideline for design evaluation.

This paper examined some problems of media coverage of religion by analyzing a television documentary. The SBS-TV documentary "God's way Man's way" aired in 2008, critically presented the basic Christian doctrine. The producers of the program estimate that protestant churches in Korea have become an established power, which has influence on a societal and political level. Therefore the producers believe that they have the right to criticize that power, especially because its doctrine about salvation leads to serious conflict with other religions, for example, Islam. This program portrayed the doctrine of Jesus as a story borrowed from ancient myths. Consequently, there were harsh protests from the Korean Christian milieu, especially protestants. The author agrees that it is important for the media to critically cover the activities of religious institutions and the behaviors of religious people in the civil society. However, if producers of a documentary want to introduce controversial doctrines of one religion to an audience, they should present the orthodox ones with alternatives or opposing ones, according to the principle of objectivity and fairness of journalism. Since every religion has its mysterious doctrine that cannot be proven by science and reason, journalists should not criticize the sacred part of religion. This paper suggested some ethical points to the media, children of Enlightenment Age, when they cover the religion including its doctrine and mysterious parts.

Digital convergence put a huge challenges for broadcast media in terms of integrating user generated content (UGC). Keeping this in mind, objective of the study is to explore the factors that affecting UGC's integration in Broadcast channel from developing countries' perspective. We explored how and why UGC are appearing in Bangladeshi Television news. In-depth interview was used and news editorial level staffs were selected from leading Bangladeshi television channels. Findings suggest that, state interventions in crisis events and lack of experiences to handle crisis reporting played a crucial role to incorporate UGC in television news bulletins. One of the significant findings is that, mere traditional guidelines and work policy of the media houses will not be enough to handle user generated content as well as citizen's participation in news media. Thus, we recommend to formulate a comprehensive user generated content integration policy in the context of Bangladesh.

인터넷상에서 멀티미디어 영상회의를 적용하기 위해서는 대역폭 확보가 중요하다. 예를들면 RSVP를 이용하여, 서비스를 제공하기 위해 실제 데이터 전송 경로를 따라 필요한 패킷망의 자원을 미리 예약함으로써 실시간 멀티미디어 데이터 전송을 가능하게 한다. 그러나 현재의 인터넷 환경에서 멀티미디어 영상회의를 위한 오디오/비디오 스트림 데이터를 다수의 사용자가 상업적으로 사용하기에는 대역폭 차원에서 한계를 지니고 있다. 본고에서는 ISDN 및 인터넷의 혼합된 환경에서 전자상거래를 위한 다지점 멀티미디어 회의를 적용하는 방법론에 관하여 논하고자 한다. 이를 위해 다지점 환경하에서 응용프로그램 공유, 화이트보드 및 파일전송 등 데이터 공동작업을 위한 프레임워크를 보이고 전자상거래에 다지점 멀티미디어 적용시 거래자들간의 상호 연동성을 보장하기 위한 표준모델을 제시 하고자 한다. 이를통하여 인터넷과 N-ISDN을 이용하여 웹상에서 다지점 멀티미디어 회의를 전자상거래에 적용하기 위한 온라인 서비스을 제시하고자 한다.
