일반국도의 상시조사 자료는 교통량 조사 장비를 통해 수집되며, 수집된 자료가 누락되거나 불량일 경우 통계자료의 객관성을 유지하기 위해서 보정을 해야 한다. 교통량 결측 자료의 보정을 통계적인 방법으로 접근하여 신뢰성을 높이고자 본 연구에서는 보정 대상 시간과 동일시간의 자료를 적용할 수 있는 자기회귀분석과 보정 대상 지점과 동일 지점의 자료를 적용할 수 있는 계절 시계열 분석을 이용하여 보정하는 방안을 제시하였다. 계절 시계열 분석을 적용하여 결측 자료를 보정한 결과, 결측 기간이 길어질수록 오차가 커지는 것으로 분석되었다. 이것은 단기예측의 경우 실제자료를 이용하여 예측 값을 제시하지만, 장기예측의 경우 예측된 자료를 이용하여 예측값을 제시하기 때문에 신뢰성이 떨어지기 때문이라 판단된다. 자기회귀분석을 적용하여 결측 자료를 보정한 결과, 시계열분석에 비해서 오차가 적은 것으로 분석되었다. 이것은 교통량자료는 과거 패턴보다 현재 시점의 영향을 더 많이 받는 것이기 때문이라 판단된다 하지만 자기회귀분석은 인근에 패턴이 유사한 지점이 있어야 가능하며, 인근에 유사한 지점이 있더라도 그 지점의 자료가 불량일 경우 보정이 불가능하다는 단점이 있다. 이러한 경우에는 과거자료를 이용해서 보정할 수밖에 없으며, 단기 결측의 경우에는 시계열분석을 이용할 수 있다.

지능형 교통체계(ITS)는 검지시스템의 지원으로 도로 현장에서 전개되는 교통상황을 실시간 모니터링 한다. 또한 이렇게 수집된 교통자료는 다양한 처리 및 가공 기법을 적용하여 교통운영, 교통계획, 교통안전 등 교통분야에서 다양하게 추가 활용된다. 그러나 실시간으로 검지되는 교통자료에 대한 활용 및 신뢰성이 선진 외국에 비해 낮은 실정으로 신뢰성 있는 교통정보 제공 및 분석을 위하여 교통자료의 품질확보가 우선 되어야 한다. 품질확보를 위한 기존의 연구에서는 기본 자료처리 3단계인 이상치 검지 및 제거, 결측자료 보정, 평활화 각각에 대한 알고리즘 및 관련 파라메터 추정에 초점이 맞추어져 왔다. 그러나 각각의 자료처리 과정은 사용자의 궁극적인 자료 활용목적에 따라 다양한 상호연관성을 나타낸다. 따라서 사용자에게 보다 신뢰성 높은 교통자료를 제공하기 위해서는 자료처리 기법을 통합평가할 수 있는 방법론 및 도구가 필요하다. 본 연구에서는 차량 검지기로부터 수집되는 교통자료의 통합평가 방법론을 연구하였고, 사용자의 자료 활용 목적에 부합하는 교통자료를 손쉽게 추출할 수 있는 도구를 개발하였다. 교통자료 품질확보를 위하여 자료처리 방법선택, 입력파라미터 선택, 자료처리 알고리즘 등록이 가능하도록 하였으며 품질확보를 위하여 반복적 자료처리가 가능하도록 하였다. 또한, 실제 경부선 2개구간에서 수집된 교통자료를 본 연구에서 개발한 방법론 및 도구에 적용한 사례를 제시하였다.

Over the last few years, streaming audio and video content on Internet sites has increased at unprecedented rates. The predominant method of delivering video over the current Internet is video streaming such as SureStream or Intelligent Stream. Since each method provides the client with only one data stream from one server, it often suffers from poor qualify of pictures in the case of network link congestion. In this paper, we propose a novel method of delivering video stream based on wavelet to a client by utilizing multi-threaded parallel connections from the client to multiple servers and to provides a better way to address the scalability functionalities. The experimental results show that the video quality delivered by the proposed multithreaded stream could significantly be improved over the conventional single video stream methods.

Different from traditional development methodologies like waterfall model, the CBD (component based development) methodology relies on a building block approach in the design and development of information system. The audit procedure and checklist for the traditional IS development methodology are required to be modified to be suitable for CBD. This research reviewed IS audit guidelines for the existing development process and analyzed multiple projects that employed the by component based development process. For the purpose of this study, we chose a governmental project and a next-generation IS project of a financial agency as sample cases. By comparing existing IS audit checklists and items actually reviewed in audit projects, this study identified appropriate check items for the CBD-centric audit program. New items were proposed as additional items such as project control in management phase, usage case and conceptual model establishment, component evaluation and design, in implementation phase, and so forth. The result of the research provides new guidelines for the audit CBD projects for the purposed of increased efficiency and qualify of application development projects.
