Recently, among the computational methods of protein-protein interaction prediction, vast amounts of domain based methods originated from domain-domain relation consideration have been developed. However, it is true that multi domains collaboration is avowedly ignored because of computational complexity. In this paper, we implemented a protein interaction prediction system based the Interaction Significance matrix, which quantified an influence of domain combination pair on a protein interaction. Unlike conventional domain combination methods, IS matrix contains weighted domain combinations and domain combination pair power, which mean possibilities of domain collaboration and being the main body on a protein interaction. About 63% of sensitivity and 94% of specificity were measured when we use interaction data from DIP, IntAct and Pfam-A as a domain database. In addition, prediction accuracy gradually increased by growth of learning set size, The prediction software and learning data are currently available on the web site.

This paper is to provide the method of dynamic service composition in ubiquitous environment. This method is extended of Service Component Architecture, which is a standard about service composition. This standard only supports service composition in system design time. It has problem we cannot it ubiquitous environment, requests dynamic service composition. To solve this problem, we suggest dynamic service composition method based on SCA.

가속기 진공시스템은 대형 초고진공장치로 운전 중 10-9 mbar 유지를 목표로 하고 있다. 이 같은 수준의 초고진공은 배기시스템을 적절히 설계하고 베이크아웃을 함으로서 얻을 수가 있다. 베이크아웃은 보통 1~3일 소요되므로 운전 중 빠른 복원을 힘들게 하는 원인중 하나이므로 최근에는 베이크아웃 하지 않도록 설계하는 추세이다. 이 연구에서는 네그펌프-이온펌프를 조합하여 설계하고 베이크아웃하지 않으면서 초고진공을 원하는 시간 내에 달성 하도록 목표로 하고 있다. 이 발표에서는 대형 이온펌프를 사용하고 베이크아웃하는 전통적인 방법과 조합펌프를 사용했을 때 진공배기를 비교 실험하여 그 결과를 보고하고자 한다.

본 논문에서는 조합논리회로의 테스트 컴팩션을 위한 두 가지 효율적인 알고리즘을 제안한다. 제안된 알고리즘들은 각각 동적인 컴팩션 기법과 정적인 컴팩션 기법을 사용하고 있으며, 실험을 위해 기존의 ATPG시스템인 ATALANTA에 통합 구현하였다. ISCAS85와 ISCAS89(완전스캔 버전) 벤치마크 회로에 대한 실험에서 본 시스템은 기존에 발표된 다른 컴팩션 알고리즘에 비하여 보다 작은 테스트 집합을 보다 빠르게 생성하였으며, 실험 결과를 통하여 제안된 알고리즘들의 유효성을 입증할 수가 있었다.

This paper defines an effectiveness index for optical continuous observation of unknown space objects and presents a range of design variables combinations that can satisfy the effectiveness index from a telescope/mount control system perspective using integrated simulation. The overall system-level simulation was implemented and the tracking performance was analyzed by considering design variables such as target position prediction and frame rate, image processing time and measurement error, target trajectory characteristics, and maneuver performance of mount gimbal. As a result of the analysis, it was confirmed that the continuous tracking performance of the optical observation system is dependent on the combination of frame rate and mount maneuver performance. In a situation where an optical observation system is designed or a similar system is implemented using COTS, an appropriate combination of parameters between design variables can be found through effectiveness analysis simulation as in this study.
