현재 대부분의 전자경매 시스템들은 기존의 경매소와 경매인들에 의해 이루어졌던 경매진행과 관리기능을 하나의 서버프로그램으로 통합하여 제공하고 있다. 하지만 이러한 시스템들은 기존 경매소에서 이루어졌던 기능들의 독립성과 분산성 그리고 병렬성을 충분히 구현하지 못하고 있다. 또한 기존의 이러한 시스템들은 단지 경매관리와 진행만을 온라인상에서 자동화하였을 뿐 경매는 여전히 경매참여자들이 원격접속을 통해 직접 입찰하는 것을 요구하고 있다. 따라서 경매참여자는 수시로 변하는 경매 진행상황을 파악하고 적절한 입찰가격을 결정하여 입찰하는 반복적인 작업을 계속해야 한다. 그리고 기존 시스템들이 갖는 또 다른 제한으로는 다양한 경매 유형을 지원하지 못한다는 것이다. 현재 대부분의 전자경매 시스템에서 지원하고 잇는 경매유형은 영국식 또는 네델란드식을 포함해 단일경매가 대부분이며, 속도와 효율성 그리고 경매참여자의 이익면에서 우수한 다중경매를 지원하지 못하고 있다. 이러한 문제점들을 해결하기 위하여 본 논문에서는 다중 에이전트 기반의 연속다중경매 시스템인 CoDABot을 설계하고 구현하였다. 이 시스템에서는 연속다중경매를 지원하고 경매참여자인 사용자를 대신해 입찰할 수 있는 다양한 유형의 입찰 에이전트를 제공한다. 따라서 경매관리와 진행의 효율성을 위해 사용자 인터페이스 시스템으로 전체 시스템을 구현하였다.

Recently, a GIS has been applicable to the most important computer applications such as urban information systems and transportation information systems. These applications require spatial operations for an efficient management of a large volume of data. In particular, a spatial join among basic operations has the property that its response time is increased exponentially according to the number of spatial objects included in the operation. Therefore, it is not proper to the systems demanding the fast response time. To satisfy these requirements, the efficient parallel processing of spatial joins has been required. In this paper, the efficient method for creating and allocating tasks to balance statically the load of each processor in a parallel spatial join is presented. A task graph is developed in which a vertex weight is calculated by the cost model I have proposed. Then, it is partitioned through a graph partitioning algorithm. According to the experiments in CC16 parallel machine, our method made an improvement in the static load balance by decreasing the variance of a task execution time on each processor.

The purpose of this study was to provide basic information on leisure participation and leisure exploration of community-dwelling stroke patients through a multi-dimensional leisure participation evaluation tool. The subjects in this study were 35 people living with stroke in the community. As a result of study, the most involved leisure activities were in order of watching TV, communicating, and exercise alone. Most of the satisfaction level of leisure participation was 7-10 points, but exercise alone was 5.2 points due to the purpose of health management. Leisure exploration was the most frequent exercise alone and sports, and interest was 8-10 points. The most important obstacles for leisure participation were physical problems depending on the nature of the stroke disease. Through the results of this study, it is necessary to activate a stroke patient's discharge plan and activate a community stroke patient's leisure intervention program so that they can participate in leisure activities of their choice through voluntary leisure exploration.
