The purpose of this study was to investigate representation of media on Korean controversial historical incidents and its myth and ideology. Especially the authors paid attention to the MBC-TV Documentary which had dealt with many controversial issues in Korean society. Those issues had never been dealt by other Korean media before it began to do. Three episodes about the South-North Korea related issues were selected as main object of this study and were analyzed with various semiotic research methods, especially, paradigmatic analytical method, narrative analytic method and mythical analytic method. As a main result of this study, it was found that the Documentary tended to represent such controversial historical issues very differently from the previous representations of old newspapers'. Th e old newspapers tried to establish old myths; that is, 'myth of national crisis', 'myth of anti-communism', 'myth of scapegoat of college students', 'myth of intelligent agency's monopoly', 'myth of social stablization', etc, while the documentary changed to build up new myths; that is, 'myth of humanities', 'myth of peaceful unification', 'myth of freedom and democracy', 'myth of human rights, etc.' In short, it was concluded that the documentary was able to change some previous myths and ideologies through its changing representations.

Like other organic beings, modern cities change every day. Unlike in the past, changes of space which have been taking place in concentrated spaces during short periods of time have worsened the environment of cities creating environmental problems. In particular, the urban heat-island phenomenon, which is caused by changes in using the earth's surface, has emerged as a key social issue along with health problems and economic difficulties. The Green Network has been introduced as an urban planning approach to solve the urban heat-island phenomenon. This study suggests constructing a Green Network through analyzing the urban heat island phenomenon, land cover classification, and linkage possibility with the Green Network and wind corridors by researching Jung-Gu, and Nam-Gu in Daegu Metropolitan City. In conclusion, this study presented the construction of a broad and detailed Green Network of object areas by assigning Apsan to the southern area and mountain area as the core, two areas of Nam-Gu and six areas of Jung-Gu such as Duryu Park and, Dalsung Park as footholds and other school land and park facility areas as footholds-to-be areas. In particular, Camp Walker, which is connected with Apsan, is not only a foothold but connected to the core, is necessary to preserve after being transferred from the U.S. Army. In addition, assigning the Susung Bridge area of Jung-Gu and the Camp Walker area of Nam-Gu as the wind corridor areas is recommended.

The purpose of this study was to investigate how much multi-cultural traits the multiculture-oriented TV programs would have and how they tended to represent it with what kinds of meaning structures. As an object of this study, the authors chose the Program of KBS-TV which had been discussed seriously to raise a multi-cultural issue as well as a sexuality issue of lady guests. They collected 70 weekly programs from Nov. 26 of 2006 to March 31, 2008, and finally selected and analyzed 5 weekly programs as main analytic data. They tried to analyze them with various semiotic research methods, especially, linguistic semiotic research methods and pictorial research methods. As results of this study, it was found that this Program was based on multiful-levels of meaning structure: that is, superficial level, representation level and in-depth level. The superficial level of this program presented various multi-cultural traits through many and various talks of lady guests. Its representation level indicated some patterns of discourses about issues and agendas of the talks among lady guests. The in-depth level was based on the sexuality of lady guests as well as the male-dominant ideology. It was finally implicated that this Program was based on the sexuality and feminity of lady guests even though it tried to advocate its multi-cultural traits.

This paper proposes a real-time distance measurement system of high temperature and high speed target using infrared stereo camera. We construct an infrared stereo camera system that measure the difference between target and background temperatures for automatic target measurement. First, the proposed method detects target region based on target motion and intensity variation of local region using difference between target and background temperatures. Second, stereo matching by left and right target information is used to estimate disparity about real-time distance of target. In the proposed method using infrared stereo camera system, we compare distances in three dimension trajectory measuring instrument and in infrared stereo camera measurement. In this experiment from three video data, the result shows an average 9.68% distance error rate. The proposed method is suitable for distance and position measurement of varied targets using infrared stereo system.

프레임 릴레이망을 백본으로 한 LAN과 LAN접속으로 형성되는 기업통신망이 현재 활발히 전개되면서 인터넷을 통한 광고, 전자거래가 중요한 서비스로 진행되고 있다. 국내의 프레임 릴레이 서비스 현황을 살펴보면 KT, 데이콤, 일부기업등에서 프레임 릴레이 교환기를 수입하여 주고객인 기업에 서비스를 제공하고 있다. 이들은 사용자 요구에 의해 주로 LAN과 LAN에 접속된 라우터 등의 종단 시스템간 PVC(영구가상회선: Permanant Virtual Circuit)접속을 통하여 다양한 서비스를 제공하면서 독자적인 기업통신체계를 구축하고 있는 실정이다. 이와같이 사용자 요구로 PVC등록시 프레임 릴레이망과 LAN을 연결하는 링크의 QoS(서비스 질: Quality of Service), 트래픽 파라메터는 수동적으로 설정된다. 현재 국내에서는 프레임 릴레이 교환기 개발은 전무하고 단지 그들을 수입하여 운용하는 수준이며 향후 ATM(비동기 전달모드: Asynchronous Transfer Mode)망의 중요 서비스 연동이 될 프레임 릴레이 기술은 심도있게 연구되고 있다. 향후 고속통신을 제공하는 백본망은 기존의 프레임 릴레이망과 ATM망이 공존할 추세이며 점진적으로 프레임 릴레이망은 사라질 것이다. 이때 ATM 망이 기존의 프레임 릴레이망을 백본으로 한 기업통신망 수용시 원할한 서비스 제공을 위해서는 프레임 릴레이망을 백본으로 채택한 기존의 기업통신망을 ATM망에서 수용시 야기되는 문제점의 제시와 이의 해결은 매우 중요하다고 생각된다. FR/ATM(Frame Relay/ATM)연동시 기업통신망 입장에서는 PVC뿐만 아니라 SVC(교환가상회선: Switched Virtual Circuit)호처리가 수용되어야 한다. 이와같이 PVC와 SVC 수용으로 기업통신망은 통신망의 구성 및 관리가 복잡, 다양해지며, 또 그 기업은 관련된 다양하고 수많은 고객과 접속될 수 있어야 한다. 이때 ATM망을 백본으로 한 공중망이 관련 기업의 사설 정보를 관리하도록 한다는 것은 그 서비스의 이용자에게 보안문제를 제기함은 물론 서비스 이용자가 자신의 망에서 동작하는 여러 서비스를 고객 스스로가 관리하는 것이 바람직하다. CNN(고객망관리 : Customer Network Management)은 이러한 고객에 의한 통신망, 공중망에 대한 부분적 관리 및 서비스에 대한 관리가 이루어 질수 있도록 수행하는 기능이다. 본 논문에서는 ATM망이나 프레임 릴레이망과 ATM 망이 공존시 기업통신망관점에서 야기되는 문제점의 제시와 이의 해결 방안을 살펴보았다. 우선 FR/ATM 연동에서 PVC설정뿐만 아니라 SVC 설정 방법의 연구, 이때 고려된 QoS,트래픽 처리과정을 살펴보았다. 또한 망관리 입장에서 기업통신망 관리자와 ATM망 관리자와의 온-라인 서비스를 제공하기 위해서는 변화된 통신망 차원서의 확장된 Managed Object(MO)를 근간으로한 체계적인 CNN-NMS(CNM-Network management System)연동을 살펴본후 결론에서는 추후 계속연구 및 조사 되어야 할 항목을 기업통신망 입장에서 서술하여 보았다.

Accurate information on players, namely player analytics is one of the key factors in a game development environment where a scientific approach to user-oriented game analysis is in the spotlight. This study is intended to examine effects of relations between choke point types and cover pattern properties on level difficulties in FPS games. As for FPS games, interaction between players' behaviors and game levels is higher compared to other genres and choke point types as well as cover pattern properties are key factors of level design. Choke point is the main crossroad that must to pass for achieving the goal and Cover Pattern is the type of object on the level except buildings. Two elements directly or indirectly affect the level of difficulty. This study analyzed 10 types of representative FPS gameplays to classify choke point types and assigned 4 types of cover pattern properties to organize 16 target levels for the experiment. In addition, this study collected and analyzed players' 800 behavior data (video clips) from 5 repetitive plays performed by 10 players. In conclusion, analytical results obtained from the empirical study will contribute to realizing systematic game level development by providing specific information for a game level design phase. The findings are also meaningful in that they suggest efficient and effective methods of utilizing the existing academic study results for industrial applications.

This study identified terminologies related to the proximity and frequency of disaster by social network analysis (SNA) and text mining, and then expressed the outcome into a mind map. The termdocument matrix of text mining was utilized for the terminology proximity analysis, and the SNA closeness centrality was calculated to organically express the relationship of the terminologies through a mind map. By analyzing terminology proximity and selecting disaster response-related terminologies, this study identified the closest field among all the disaster response fields to disaster response and the core terms in each disaster response field. This disaster response terminology analysis could be utilized in future core term-based terminology standardization, disaster-related knowledge accumulation and research, and application of various response scenario compositions, among others.

The typical Kinetic Family Drawing (KFD) Web database system, a form of prototype system, has been developed, relying on the suggestions from family art therapists, with an aim to handle large amounts of assessment data and to facilitate effective implement of assessment activities. However, unfortunately such a system has an intrinsic problem that it fails to collect clients' behaviors, attitudes, facial expressions, voices, and other critical information observed while they are drawing. Accordingly we propose the ontology based video event analysis and video retrieval system in this paper, in order to enhance the function of a KFD Web database system by using a web camera and drawing tool. More specifically, a newly proposed system is designed to deliver two kinds of services: the client video retrieval service and the sketch video retrieval service, accompanied by a summary report of occurred events and dynamic behaviors relative to each family member object, respectively. The proposed system can support the reinforced KFD assessments by providing quantitative and subjective information on clients' working attitudes and behaviors, and KFD preparation processes.
