본 논문은 스토리에 기반하여 여러 편의 드라마 동영상 파일 중에서 사용자가 찾고자 하는 파일을 찾아주는 검색 시스템의 설계 및 구현에 대하여 기술한다. 기존의 동영상 검색 방식은 제목 및 주연 배우와 같이 제한적인 검색어에 의한 검색을 제공하고 있으나, 대부분의 드라마 파일은 영화 또는 다른 동영상 파일과 달리 여러 회로 나누어져 있기 때문에 기존의 주연 배우나 제목과 같은 정보만을 가지고 사용자가 원하는 파일을 검색하기 어렵다. 본 논문에서는 드라마의 제작사에서 제공하는 각 회당 스토리를 기본적인 불리안 모델과 결합시켜 사용자가 원하는 회차를 검색하는데 유용한 시스템을 설계 및 구현하였다. 본 논문에서 제시한 방식의 유용성을 보이기 위하여 실제 서비스 되고 있는 드라마를 대상으로 실험을 하였으며, 실험결과 높은 검색 능력을 보이고 있다.

The geometry stage, which performs the transformation and lighting operations of vertices, became the critical part in 3D graphics pipeline. In this paper, we have planned and designed the Geometry Processor for the better and more efficient way to process the real-time 3D using the floating point unit. We also designed a verification system for Geometry engine. It is implemented with Xilinx-Virtex2 and Visual C++.NET. In the Synopsis, we confirmed 100 MHz performance and 137107 cell area of Geometry Engine.

Tension wood, a specialized tissue developed in the upper side of the leaning stem and drooping branches of angiosperm, is an attractive experimental system attractive for exploring the development and the biochemical pathways of the secondary cell wall formation, as well as the control mechanism of the carbon flux into lignin, cellulose, and hemicellulose. However, the mechanism underlying the induction and the development of the tension wood is largely unknown. Recently, several researchers suggested the possible roles of the plant growth hormones including auxin, gibberellin, and ethylene mainly based on the expression pattern of the genes in this specialized tissue. In addition, expressed sequence tag of Poplar and Eucalyptus provide global view of the genetic control underlying the tension wood formation. However, the roles of the majority of the identified genes have not yet been clearly elucidated. The present review summarized current knowledge on the biosynthesis of tension wood to provide a brief synopsis of the molecular mechanism underlying the development of the tension wood.

Thesedays more collaboration is required of scholars than before, because some complex problems are beyond the individuals' research capability. Traditional print-based journal systems have been playing a role of supporting scientific collaboration, in that they provide the state-of-the-art knowledge. Those journal systems, however, are known to have some problems. To cope with some of those problems of the print-based journal systems, electronic journal systems have been suggested and implemented. Investigation shows us that electronic journal systems still have some problems. This paper proposes a new form of electronic journal system, structured electronic journal system, which is believed to better support the scientific collaboration. It is designed so that it is easier to figure out the synopsis of an article and so that authors and referees of a submitted paper can participate in the discussion for verifying the significance of the paper. Object-oriented design of a structured electronic journal system which is to be built on top of a object-oriented database system is explained with example structures.

In recent years, progress in hardware technology has resulted in the possibility of monitoring many events in real time. The volume of incoming data may be so large, that monitoring all individual data might be intractable. Revisiting any particular record can also be impossible in this environment. Therefore, many database schemes, such as aggregation, join, frequent pattern mining, and indexing, become more challenging in this context. This paper surveys the previous efforts to resolve these issues in processing data streams. The emphasis is on specifying and processing sliding window queries, which are supported in many stream processing engines. We also review the related work on stream query processing, including synopsis structures, plan sharing, operator scheduling, load shedding, and disorder control.

Today, knowledge is considered the most strategically important resource. As research in knowledge management advances, it ought to review and categorize the already published literatures on knowledge management in the area of business strategy, accounting/finance, human resource management and management information technology. To identify the knowledge management research trend, we analyze 168 articles published in prominent academic journal during last two decades. This paper develops three stages model for knowledge management research: observation, initiation and evolution stage. Also, we classify the given researches according to the three criteria of contents, related academic area and applied research method.

We have carried out the construction of the 154kV intelligent substation with KEPRI. The Intelligent substation is built in Gochang testing facility of KEPCO and consists of electronic instruments for GIS(gas insulated switchgear), digital control panel, remote monitoring and diagnosis system, and digital relay system. Rogowski coil type CT(RCT) and capacitive voltage divider(CVD) are introduced compared with the instrument transformer of conventional type. Digital control Panel(DCP) replaces the LCP(local control panel) which is drived for mechanical operation. For the monitoring of the condition of GIS and TR, various sensors are used. In this Paper, we mention the synopsis and report the progress state of project.

모바일 단말기의 수요가 증가함에 따라 사용자들은 다양한 형태의 검색 시스템을 요구하고 있다. 모바일 환경에서는 키 입력 방식이 일반적인 개인용 컴퓨터와 상이하기 때문에 모바일 단말기의 특성에 적합한 검색 방식이 필요하다. 본 논문에서는 PDA와 같은 모바일 단말기에서 사용자가 원하는 TV 프로그램을 검색 할 수 있는 시스템을 설계 및 구현하였다. 전체 시스템은 검색 서버와 모바일 클라이언트로 구성되며, 클라이언트는 모바일 환경에서 검색어 입력을 효율적으로 할 수 있게 데이터베이스에 기반한 검색어 입력 방법을 사용하였다. 시스템의 유용성을 확인하기 위한 실험에서 이 시스템은 검색어 입력 방식과 드라마 검색 결과를 모두 만족하는 성능을 보여주었다.
