디지털 콘텐츠의 다양화와 인터넷 환경의 확산으로 인하여 디지털 유통 구조가 복잡해지면서 기존의 오프라인 형태에서 제공하는 방법으로는 새로운 유통 구조를 보호하기 힘들기 때문에 권리의 상호 침해를 방지할 수 있는 유통 구조 모델을 제시하고 이 모델에 적용할 수 있는 프로토콜 체계를 수려하여야 한다. 본 논문에서는 인터넷 환경에서 디지털 콘텐츠의 유통에 관여하는 유통 주체(Entity)들의 권리를 보장할 수 있는 메타데이터를 분류하였다.

한국의 TMD 참여문제는 실효성 문제, 경제적인 문제, 기술적인 문제 등으로 볼 때 유보하는 것이 바람직하다고 생각된다. 따라서 북한의 탄도 미사일에 대한 방어체계 구축은 동맹국의 TMD 체계와 상호 운용성을 보장할 수 있으며, 주변국으로부터 군비 확충에 대한 의심을 불식시킴과 동시에 한국적 여건에 가장 적합한 미사일방어체계(KAMD:Korea Air and Missile Defense)에 대한 개념연구의 선행이 필요하다.

세계적인 군축분위기속에서 우리나라의 막대한 국방비 지출이 전시에 대한 대비는 물론, 평화시에도 국가발전의 디딤돌이 되고 있다는 인식을 확산시킬 필요가 있습니다. 이와함께 우리나라의 항공우주정책이 과거와 같은 조달중심의 정책에서 개발중심의 정책으로 전환되어야 할 것이며, 국가경제에서 차지하는 국방비의 비중을 고려해서라도 국방 연구개발(R&D)이 국방차원에서 머물러서는 안될 것입니다

Epidemiological models on disease spread attempt to simulate disease transmission and associated control processes and such models contribute to greater understanding of disease spatial diffusion through of individual's contacts. The objective of this study is to develop an agent-based modeling(ABM) approach that integrates geographic information systems(GIS) to simulate the spread of FMD in spatial environment. This model considered three elements: population, time and space, and assumed that the disease would be transmitted between farms via vehicle along the roads. The model is implemented using FMD outbreak data in Andong city of South Korea in 2010 as a case study. In the model, FMD is described with the mathematical model of transmission probability, the distance of the two individuals, latent period, and other parameters. The results show that the GIS-agent based model designed for this study can be easily customized to study the spread dynamics of FMD by adjusting the disease parameters. In addition, the proposed model is used to measure the effectiveness of different control strategies to intervene the FMD spread.

The success of the journey to the west of tvN's shows the positive prospect of web entertainment. This study highlights how viewers actively select web progrmas and how they diffuse the infomrmation of web programs to explore the possibility of success of web program and the change of viewing environment. This study revealed the attention of viewers affected the diffusion of programs via social media. The highness of the viewer's attention cause the highness of active interaction between users. The production company of web entertaninment has to focus on the high hits strategy. In the view of journalists, they covered on the appearance of the heroin rather than the content of the program. The relationship of viewing type and viral type via SNS is related with the activity of viewers. If viewers participate in viewing they express their opinion on the web entertainment actively.

A real-time dose assessment system(FADAS : Following Accident Dose Assessment System) has been developed for the real-time accident consequence assessment against a nuclear accident. Field tracer experiment near Younggwang nuclear power plant was performed to improve the accuracy of developed system and to parameterize the site-specific parameters into the FADAS. The mean values and turbulent components of wind profile obtained through field experiment have been reflected to FADAS with site-specific conditions. The simulated results of diffusion model agreed well with the measured data through tracer experiment. The developed system is being used as a basic module of emergency preparedness system in Korea. The diffusion model which can be reflected site-specific parameters will be improved through field experiments continuously.

A two-dimensional depth-integrated hydrodynamic and a depth-averaged passive scalar transport models were developed by using a Compact Finite Volume Method (CFVM) which can assure a higher order accuracy. A typical wave current interaction experimental data set was compared with the computed results by the proposed CFVM model, and resonable agreements were observed from the comparisons. One and two dimensional scalar advection tests were conducted, and very close agreements were observed with very little numerical diffusion. Finally, a turbulent mixing simulation was done in an open channel flow, and a reasonable similarity with LES data was observed.
