2002년 월드컵 전야제에서는 한국문화를 소개해 세계인의 환호를 받았는데 그 중에는 칠석동 민속축제인 고싸움놀이가 펼쳐졌다. 칠석동 민속축제는 일반 서민복식의 전통복 형태를 보여주는 복식(服飾)을 실제 착용하고 축제를 행하고 있으므로, 점차 사라져 가는 전통복식을 놀이문화를 통해 직접 확인할 수 있다는 점에서 연구가치를 갖는다. 본 연구의 목적은 국제화 시대에 우리 전통문화에 대한 정체성 확립을 위해 시대적 변화에 따라 변해 가는 민속복식을 무형문화재로 지정되어 있는 칠석동 고싸움놀이를 중심으로 시대적 흐름을 통한 고싸움놀이의 전수과정에서 형성되어 온 민속축제복식의 구성과 특성을 살펴보는데 있다. 연구방법은 광주지역인 광산구 칠석동 마을을 중심으로 자료조사와 현장조사를 병행하였다. 자료조사는 민속에 관련된 전공서적과 무형문화재 조사보고서, 행사팜플렛 등을 참고하였고, 현장조사는 고싸움 축제에 참가하여 복식 전반에 대한사진촬영과 마을축제 참여하는 마을사람들을 중심으로 축제복식에 관한 면담조사를 하였다. 칠석동 고싸움 축제복식은 행사가 진행되는 내용에 따라 크게 4가지로 분류할 수 있는데 본격적인 고싸움이 시작되기 전날 밤에 당산나무에 제를 지내는 당산제 복식, 마을의 평안과 고싸움의 흥을 돋우기 위한 농악복식, 고싸움이 시작되기 전에 아낙네들이 손과 손을 맞잡고 둥글게 돌며 화합을 다짐하는 강강수월래 복식, 한해 풍년을 기원하는 고싸움복식이 있다. 칠석동 고싸움 축제복식의 특성을 요약하면 다음과 같다. 첫째, 구성면에서는 농경제의(農耕祭衣)와 안택축원(安宅祝願的)을 기원하는 민속놀이축제복식으로 일상생활에 착용하는 복식을 이용한 농경 의례복의 다(多)기능성이 강조된 것으로 나타났다. 둘째, 색상은 우리조상의 백의(白衣)의 상징인 일상복인 백색 위에 오방색을 사용하여 화려하고도 강렬한 원색의 색상조화가 특징적으로 나타났다. 셋째, 형태면에서는 양쪽어깨와 허리선의 면 분할이나 비례를 통해 허리부분의 동작에 따른 유동적인 선이 부각되고 있다. 특히, 평면구성의 단조로움은 흔들리는 몸동작에 따른 고름의 율동미와 축제복식의 착장 방법에 따른 한국복식의 형태미를 보여주었다.

The analysis of multi-flexible-body dynamics (MFBD) has been an important issue in the area of the computational dynamics. This technique has been developed and improved in RecurDyn solver. This paper reviews the formulation which is applied in the RecurDyn solver. Basically, in order to solve the multi-flexible-body dynamics problem, an incremental finite element formulation using a corotational procedure is used. In particular, in order to solve the rigid and flexible bodies together, a constraint equation between a rigid body and a flexible body is applied, in which a virtual body and a flexible body joint are introduced.

The proportion of video content consumption is growing dramatically but some users avoid it. The reasons are initial time to load, lack of the time to watch video content, and particularly a traffic issues on mobile devices. The proposed Video-to-Images(V2I) technology offers a new user experience to end users through converting video into images without content providers' or users' effort. Using the V2I technology, consumption methods of video content with new type of content by users and the advantages of the new user experience will be introduced. Furthermore, the overall architecture of the V2I will be explained.

The neutron kinetic analysis methods for the molten-salt reactors are quite different from those for conventional solid-fuel reactors, which do not take into account the flowing-fuel-induced neutronics effects. Therefore, for dynamics and safety analyses of the molten-salt reactor systems, the conventional kinetics codes would not be appropriate to accurately predict its transient behaviors. A point-kinetics with flowing- fuel model has been used to assess the fluid-fuel reactor system safety, but recognized as not to be sufficient to simulate spatial distributions of delayed-neutron precursors and neutron populations during transients for given detail reactor models. In order to meet this requirement, AMBIKIND, a 2-group, 2-dimensional neutron kinetics code suitable for the molten-salt reactor systems was developed. This paper explains the code's theoretical and numerical descriptions and, as a part of its verification, includes some simulation results of MSRE stability experiments. Even though the present reactor model does not include the recirculation effect of the fuel-salt through the reactor system, the AMBIKIN2D code should be able to predict the power and phase shift at various power levels and reactivity insertions with better accuracy.

Generally, either caption-based search method or content-based search methods is used to retrieve video information. However, each search method has its limitations. Caption-based search is apt to lose consistency as for user's subjects, and content-based search is hard to extract general means. To enhance efficiency and correctness as for complementing each other, we propose the Integrated Video Data Model(IVDM) which integrates the two search methods, to device the model, we analyze video data and construct the structure of video information hierarchically. IVDM supports caption-based search as assigning meta-data by analyzing thematic-unit in the higher level, and also supports content-based search as extracting feature data by analyzing the content of video data in the lower level. We design Object-Oriented database schema of news video, based-on the IVDM. And we provide 4-type of queries and query processing algorithm to retrieve news video information.

Video-based modeling / rendering developed to produce photo-realistic video contents have been one of the important research topics in computer graphics and computer visions. To smoothly combine original input video clips and 3D graphic models, geometrical information of light sources and cameras used to capture a scene in the real world is essentially required. In this paper, we present a simple technique to estimate the position and orientation of an optimal light source from the topology of objects and the silhouettes of shadows appeared in the original video clips. The technique supports functions to generate well matched shadows as well as to render the inserted models by applying the estimated light sources. Shadows are known as an important visual cue that empirically indicates the relative location of objects in the 3D space. Thus our method can enhance realism in the final composed videos through the proposed shadow generation and rendering algorithms in real-time.

This study examined whether mobile OTT video service substitutes home TV by using 3 screen data of Nielson-KoreanClick. According to the 2SLS estimation results, when the time spent on mobile OTT video service increased by 1% p, the time spent watching home TV decreased by 12.4%. The results also showed that 1%p increase in the time spent using YouTube app and the mobile OTT video services provided by telecommunication company(Oksusu, Alleh TV, VideoPortal) reduced the time spent on watching terrestrial channels on TV by 16.2% and 23.9%, respectively. The displacement of mobile OTT video service on home TV will be accelerated in the near future. In order to resolve the issue of regulatory unfairness with pay TV services and to safeguard viewer's interests, discussions to establish regulation for OTT video services should be taken place more quickly.
