An experimental investigation has been performed on the steady flow in exhaust system. When individual flow coming from exhaust manifold entered UCC, the inlet conditions at entry to the diffuser in UCC were affected by the upstream pipe and manifold works. But those effects of the inlet condition on flow through monolith are negligible because the flows are concentrated on the center of monolith regardless of inlet flow distribution. To improve the flow distribution, we installed the cone type circular ring in diffuser of UCC. This led to increasement of flow uniformity, but there was minor increment of pressure drop.

최근 인터넷 상에서는 UCC 붐이 일고 있다. PC상이 아닌 모바일 상에서의 UCC를 지향하며 모바일을 통해 칵테일 관련 동영상을 재생시키는 기술에 대하여 연구하였다. 칵테일에 대한 동영상을 직접 촬영하였으며 동영상 포맷을 모바일 상에서 적합한 형식으로 변환하는 과정을 겪었다. 다운로드 서버를 설계해 모바일 상에서 우리 팀이 촬영한 UCC 동영상을 다운로드 받을 수 있게 시스템을 구현하였다.

In this paper, on-demand service streaming protocol for user-created contents in digital cable broadcasting environment is considered. In order to provide variety media contents service like UCC in digital cable broadcasting environment, the same service model as RVOD(Real Video on Demand) is required and the different interface for each broadcasting platform is needed in a current OCAP environment. Using return path based RTP, we separate existing VOD stream band into broadcasting and VOD stream band. In order to broaden On-demand service, consistent expansion of the infrastructure same as live broadcasting system is inefficient in the digital cable broadcasting environment. Using existing network protocol, the service which is insensitive to the infrastructure for VOD service becomes possible. Therefore we considered the analysis of the class of download available structure in the Set-Top-Box for RTP(Real-time Transport Protocol) and designing the decoding available streaming server for UCC transcoding and transmission in the receiver. Designing a efficient VOD service and system under the broadcasting environment gives a expansion of On-Demand service and more chance to upload and utilization of contents.

This paper introduce a satellite image based blog system built by JeonNam local province. Main goals of this system are as follows : (1)Overcome the static aspect of traditional Web-GIS, (2)Providing a geoUCC generating platform by combining multimedia technology and GIS in a single web environment, (3)Building a two-way Web-GIS through user's participation, (4)Creating a new communicative way between government and citizen by using this system. As a result of the system building, this system enables users to create his/her own UCC(User Created Contents) on high-resolution satellite image and enables users to share his/her own UCC with other system using Web2.0 technology.
