The main factors of radar signals used in electronic warfare are Radio Frequency(RF), Pulse Repetition Interval(PRI), Pulse Width(PW), Scan Parameter(SP) and so on. This radar signals may have some important information for the electronic warfare. So, there is a necessity for making a threat database to decide whether the radar signal is a threat or not. When the electronic support system collects some threat radar signals, it needs the search band to control the receivers and filter banks of the system. In this paper we propose search band implementation considering the type and center frequency of the receivers of the electronic support system.

We employed a hierarchical document classification method to classify a massive collection of electronic medical records(EMR) written in both Korean and English. Our experimental system has been learned from 5,000 records of EMR text data and predicted a newly given set of EMR text data over 68% correctly. We expect the accuracy rate can be improved greatly provided a dictionary of medical terms or a suitable medical thesaurus. The classification system might play a key role in some clinical decision support systems and various interpretation systems for clinical data.

정보 사회에서 교육 패러다임의 급격한 변화는 학교, 교사, 학생의 역할 변화를 포함하고 있다. 수업의 방향이 교사주도에서 학습자 주도로 바뀌어감에 따라 학생들은 자기 주도적 학습을 수행하는 동안에 다양한 지원을 필요로 한다. EPSS(Electronic Performance Support System)는 기업체, 기관, 학교 등에서 업무 수행자가 원하는 순간에 지원을 의뢰할 수 있는 수행 지원 시스템으로, 본 논문에서는 이러한 EPSS를 프로토타입으로 설정하여, 학습 패러다임의 변화를 지원해 줄 수 있는 ELSS(Electronic Learning Support System)에 관한 모델 개발을 시도하고 학습 적용 가능성을 타진하였다. 먼저, EPSS에 관한 다양한 이론들을 고찰해 보았고 이를 토대로 ELSS의 개념, 설계시 고려사항, 구성요소 등으로 구성된 ELSS 모델을 제안하였다.

Computer-aided logistics support system is recognized an essential system to reduce supply and maintenance cost, and to improve readiness of weapon system or operationable composite machines. According to these trends, this paper focuses on the design scheme and the computerization strategy of information management system for Integrated Logistics Support (ILS) work. Suggested system. LAMIS(Logistics support Analysis Management Information System) is a total system that composed of Logistics Support Analysis Management information system (LSAM), Configuration Management Information System (CMIS), Maintenance Management Information System (MMIS), Project Management System (PMS) and Information Retrival System(IRS) etc. Also, LAMIS is a computerized tool that improves current supply and maintenance support program, that attempts to reliable requirment analysis of logistics support elements, and that supports to use the existing technical specification of similar one when weapon system acquisition project is started newly. When LAMIS implication is completed, it can be applied to logistics support of defense or commercial site. Straightway, LAMIS will be enhanced with computer - aided design system, engineering drawing system, interactive electronic technical manual system, electronic data interchange system, and three dimensional simulation system to weapon system configuration. When that is done, LAMIS is CALS system.

Transmission System Operators are governed by operational security standards that are applied in real time. During system disturbances, the System Operators must rely on the installed protection and control equipment, prior to human intervention. New power electronic solutions bring rapid and repeatable responses to disturbances, which will help System Operators to guarantee a stable system. Last year, Alstom completed the world's first competitively bid STATCOM to support the voltage on National Grid's 400kV network that supplies London and the Southeast from the north of the UK. It is rated ${\pm}75MVAr$ and forms part of a Static Var System (SVS) with a total rating of 0 to 225MVAr. This paper will describe the reasons for its size, location, its chain-link configuration and give examples of its operating performance. The paper will also describe the features that allow this STATCOM to deliver much more than reactive compensation in support of a wider transmission service objective, as system conditions require.

This thesis examines the problems faced in the electronic bill of lading for which improvements are necessary, and suggests various ways of overcoming those problems. First, to build a negotiation system for electronic B/Ls, active participation from related parties in addition to the government support is essential. Second, electronic B/Ls cannot be utilized within a short period of time in current commercial practices. Third, there should be infrastructure which connects all parties of international commerce through an electronic system. Fourth, instead of promoting mutual recognition through international treaty, there should be a plan which legally specifying mutual recognition between certification authorities. Fifth, it is needed to ease the strictness of electronic signature to promote the global negotiation of electronic B/Ls. Lastly, in prima facie weight of evidence, there was a significant difference with the Rotterdam Rules even in comparison with the Commercial Act which was amended with the significantly advanced rules on electronic B/L. He believed there should be a discreet consideration on these matters at the revision of the Commercial Act. For this, the government has to provide support more aggressively with more interest and commitments.

The effects on system availability, operation, and support costs were analyzed using the M&S system (MPS). The failure frequency items of current armored vehicles were identified and the MTBF of the identified items was improved. The results of this study suggest that when we reduce the frequency of failure, the availability increases, and the operation and support costs decrease. By improving the reliability of the failure frequency items, it becomes possible to upgrade or develop the weapons systems. Through this study, we confirmed that improving reliability will enhance combat readiness and reduce operation and support costs.

Technology use can dramatically enhance teachers' performance in teaching and administrative tasks. An Electronic Performance Support System (EPSS) is a versatile tool that could provide just-in-time and on-the-job training when teachers need it. In order to design an effective EPSS for teachers, it is critical to identify their needs. This study used interviews to identify teachers' needs for technology by asking them about their workloads, the difficulty and time demands of tasks, and useful technologies. The implications of the findings for the design of an EPSS are discussed, including the necessity of an adaptive design of the EPSS.

본 논문은 HELPS라는 반도체 검사 장비를 위한 전자성능지원시스템(Electronic Performance Support System)에 대하여 기술한다. 본 시스템의 목적은 운영 지원, 훈련, 지식 기반 고장 진단 및 수리를 위한 just-in time. on-the-job 멀티미디어에 기반을 둔 정보를 제공함으로써 오퍼레이터의 생산성을 향상시키는데 있다. HELPS는 운영 모듈과 고장 진단 모듈로 구성되어 있다. 운영 모듈은 사용자에게 장비에 관한 자세하고 쉽게 접근이 가능한 정보를 제공하기 위하여 멀티미디어와 하이퍼미디어를 사용한다. 멀티미디어는 정지 화상, 동화상, 에니메이션, 텍스트, 그래픽, 오디오를 포함하는 다매체 형식을 통합한다. 하이 퍼미디어는 계층적인 정보 구조를 통하여 숙련된 오퍼레이터에게는 작업을 수행하는데 필요한 특정한 정보만을 제공할 뿐만 아니라, 초보 오퍼레이터에게는 자세한 시스템 안내와 정보를 제공한다. 고장 진단 모듈은 오퍼레이터가 장비의 고장을 진단하고 수리하는 것을 자원하기 위하여 전문가 시스템과 멀티미디어를 통합하여 구성하였다. 전문가 시스템을 사용하여 진단한 다음, 멀티미디어에 의한 어드바이스가 텍스트를 포함한 정지 화상이나 음성을 포함한 동화상에 의해 제시된다. HELPS는 훈련 시간과 고장 진단 및 수리 시간의 측면에서 평가되었고, 본 시스템 사용 전에 비하여 약 30%이상의 시간을 절감함으로써 생산성 향상에 크게 도움이 된다는 것을 확인하였다. 앞으로 본 시스템은 ICAI와 가상현실 기법 등을 이용하여 확장된다면 더 많은 생산성 향상을 기대할 수 있을 것이다.
