A significant amount of research has focused on the development of highly parallel architectures to obtain far more computational power than conventional computer systems. These architectures usually comprise of a large number of processors communicating through an interconnection network. The VLSI (Very Large Scale Integration) and WSI (Wafer Scale Integration) cellular arrays form one important class of those parallel architectures, and consist of a large number of simple processing cells, all on a single chip or wafer, each interconnected only to its neighbors. This paper studies three fundamental issues in these arrays : fault-tolerant reconfiguration. functional reconfiguration, and their integration. The paper examines conventional techniques, and gives an in-depth discussion about fault-tolerant reconfiguration and functional reconfiguration, presenting testing control strategy, configuration control strategy, steps required f4r each reconfiguration, and other relevant topics. The issue of integrating fault tolerant reconfiguration and functional reconfiguration has been addressed only recently. To tackle that problem, the paper identifies the relation between fault tolerant reconfiguration and functional reconfiguration, and discusses appropriate testing and configuration control strategy for integrated reconfiguration on VLSI and WSI cellular arrays.

본 논문은 탬플릿을 기반으로 하는 새로운 정보시스템 개발 방법을 제시하고 있다. 이 개발 방법은 재사용을 극대화하여 개발 생산성을 향상시키고, 일관성 있는 설계 패턴을 유지하여 개념적 무결성을 유지하는데 목적을 두고 있다. 템플릿의 설계는 다양한 컴포넌트를 조립하여 구현하는 방법을 채택하였는데, 이는 객체지향의 중심 개념 중의 하나인 구성관계 개념에 기반을 둔 것이다. 템플릿을 적용하여 정보시스템의 개별 기능을 구현하는 방법은 유전관계 개념에 기반을 두고 있는데, 템플릿과 유전관계를 설정하여 속성과 연산을 유전 받은 후, 속성과 연산의 일부를 재구현하여 개발하는 방법을 채택하였다. 특히, 재구현을 감안한 연산에 대한 메소드 구현 방법을 제시하여 템플릿 설계의 난제를 해결하였다. 템플릿을 대상으로 성능 평가와 개선 방안도 제시하였다. 제시된 방법의 적용 사례 분석을 통해 실용성을 검증하고 있다.

Vegetation affects water level change and flow resistance in rivers and impacts waterway ecosystems as a whole. Therefore, it is important to have accurate information about the species, shape, and size of any river vegetation. However, it is not easy to collect full vegetation data on-site, so recent studies have attempted to obtain large amounts of vegetation data using terrestrial laser scanning (TLS). Also, due to the complex shape of vegetation, it is not easy to obtain accurate information about the canopy area, and there are limitations due to a complex range of variables. Therefore, the physical structure of vegetation was analyzed in this study by reconfiguring high-resolution point cloud data collected through 3-dimensional terrestrial laser scanning (3D TLS) in a voxel. Each physical structure was analyzed under three different conditions: a simple vegetation formation without leaves, a complete formation with leaves, and a patch-scale vegetation formation. In the raw data, the outlier and unnecessary data were filtered and removed by Statistical Outlier Removal (SOR), resulting in 17%, 26%, and 25% of data being removed, respectively. Also, vegetation volume by voxel size was reconfigured from post-processed point clouds and compared with vegetation volume; the analysis showed that the margin of error was 8%, 25%, and 63% for each condition, respectively. The larger the size of the target sample, the larger the error. The vegetation surface looked visually similar when resizing the voxel; however, the volume of the entire vegetation was susceptible to error.

무엇보다도 중요한 것은 국내여건이 선진국과는 상이하기 때문에 외국의 통합환경관리제도를 기초로 하여 한국형 통합환경관리제도를 어떻게 국내 여건에 맞는 맞춤형 제도로 재구현해 낼 것인가를 고민해야 할 것이다. 단순히 새로운 제도 창출에 그치지 않고, 환경질을 개선하며 사업장에 실질적인 편익을 발생시킬 수 있는 윈윈(Win-Win)정책으로 승화시켜야 할 것이다.
