Simulation is known to be a valuable tool for design and operation of Flexible Manufacturing Systems(FMSs) under study. However, in order for simulation to be useful, lots of knowledges about the behavior of system to be designed, statistics for output analysis, modeling techniques and a specific simulation language are required by the simulationist. In this paper a way to build simulation support system for nonexperts at simulation will be described and a simulation support system for FMS design and operation developed by the authors will be demonstrated.

제설제는 동절기 도로 위의 눈을 녹이기 위하여 사용되고 있으나, 서울과 같은 대도시에서 교통이 밀집한 도로 시설물의 열화를 촉진시키는 주요 요인 중의 하나이다. 도로 시설물의 합리적인 유지관리 전략을 수립하기 위하여 제설제에 노출된 도로 시설물의 환경분석이 필요하다. 본 연구는 서울시의 적설량 및 사용된 제설제량을 토대로 외래 염소농도를 계산하였다. 평균 표면 염소이온량을 구하고자 서울시의 5년간 기후환경 및 제설제 사용량을 이용하였으며, 주간선 및 보조간선율 17.5 ~ 30%, 제설제 노출 유효면적율 50 ~ 80% 수준에서 검토하였는데, 농축 속도는 0.073~ 0.077%/년, 최대 표면 염소이온량은 콘크리트 중량대비 2.2 ~ 2.31% 수준이었다. 본 연구결과는 염소이온 프로파일의 예측 또는 콘크리트 구체의 화학적 부식정도 등으로 종합적인 유지관리 대책을 수립하는데 활용될 수 있을 것으로 기대된다.

인공지능에 기반한 지능형 지휘통체체계는 복잡하고 방대한 전장정보와 전술 데이터들을 학습모델을 통해 자동으로 융합 및 추출하여 전장상황을 분석한다. 지휘관은 지능형 지휘통제체계의 상황분석 결과를 제공받아 전장인식이 가능하여 의사결정을 지원할 수 있다. 의사결정지원에 특화된 결과를 지휘관에게 제공하기 위해서는 인공지능을 학습하기 위한 실 전장상황과 유사한 전장상황분석 데이터셋 생성이 필요하다. 본 논문은 기존 선행연구인 '인공지능 기반 전장상황분석을 위한 가상 전장상황 데이터 셋 생성 연구'의 다음 단계의 데이터셋 구축 방법 연구로 지휘관의 의사결정지원 및 미래 전장인식을 위해 최종적인 전장상황분석 결과에 필요한 데이터셋을 생성하는 방안에 대해 제안하였다. 전장상황 분석용 학습 데이터셋 생성도구 SW를 설계 및 구현하였고, 구현한 SW를 이용하여 데이터 레이블 작업을 진행하였다. Siamese Network 학습모델을 이용하여 구축한 데이터셋을 입력하고, 후처리 알고리즘을 활용한 출력 결과를 도출하여 생성한 데이터셋을 검증하였다.

This study had the purpose of presenting a residential environment solution as a desirable educational environment for middle school students to grow soundly and to achieve proper self-realization while providing basic materials to build up a suitable residential environment by comparing and analyzing what relationships exist between different home backgrounds, residential environments and middle school students' social maturity. This research was conducted from Feb. 11, 2008 to Feb. 13, 2008. The subject of this research was 601 students in 3 middle schools located in Gyunggi-do. The data analyzed used the SPSS 11.5 version. The summary of this study's results is as follows. First, in terms of home background, the higher the parents' educational background and social and economic position, the greater the students' social maturity. Second, in terms of home environment, the more spacious the living space, the better the water and sewage system and rest room, the more convenient the air conditioner and kitchen system, the better the lighting, ventilation, soundproofness, insulation, the less the danger in relation to fire, crime, traffic accidents, disaster, the greater the students' social maturity. Third, in terms of the home environment related to the correlation between the residential environment and social maturity, all areas such as housing facilities, housing structural environment and housing safety showed static correlations and proved that the residential environment has an important influence on social maturity. Accordingly, in order to build up an ideal residential environment, we should make efforts to expand and improve better facilities at home considering privacy, lighting, ventilation, soundproofness, heating etc. and remove unsound factors that obstruct students social maturity and build up clean and safe residential environment with good relations with their neighbors.

In this study, in order to develop the evaluation method for XLPE materials for HVDC cables, DC/Impulse superposition testing system was builded up. Throughout the P-spice simulation, optimal values of the protection resistor for the DC generation system and the blocking capacitor for the Impulse generator were calculated. DC/Impulse superposition system showed good result maintaining their proper wave shapes and amplitudes. This system would be planned to apply to the evaluation of XLPE materials for HVDC cables.

A project has been initiated at KISTI Supercomputing Center at year 1999 to build a Tflops cluster in order to support newly emerging demands for larger scale parallel computing resources. As a supportive substitute of traditional supercompters, the cluster systems are expected to play important role in supporting diversified computational needs. In this paper, KISTI Supercomputing Center's working status of building Tflops cluster system and future plans.

Academic societies in the field of science and technology are major producers of domestic research information. These information are very important sources to researchers, students and so on. KORDIC built an integrated information system which facilitates the progress of building databases and promotes users easy access to databases. In order to build efficient society research information system, we investigated former cases and analyzed requirement of each society. We identified principal information sources and built an integrated information service system using internet homepage and information retrieval system(KRISTAL-II). In the future we will expand participating societies and focus on text-based information.

The total estimated socioeconomic logistics cost in transportation sector, including traffic congestion, household travel expenses, national macroeconomic logistics and traffic accident related cost, amount to approximately 240 trillion won a year in 2009. The amount is in increasing trend every year due to the inefficient infrastructure system in urban city roads and in intercity highways. The Government adopts the 4th National Spatial Planning (Revised) which is in progress in order to build a new physical environment ensuring people's welfare by providing the efficient and sustainable transportation networking system.

As the competition between countries has become higher and the notion of software quality has been widely spread. it has been necessary to develop technologies that can ensure and produce high quality software. With the advent of information-oriented society. quality control has to transfer to the quality control activities focused on software system instead of those activities focused on hardware system. If so, how do we get to handle the quality control on the basis of the new approach. Also, as software applications have grown. so too has the importance of software quality. In order to manage software quality, the technology to specify and evaluate both the software product quality and development process quality objectively quantitatively is most important. To produce products of good quality, we need a more progressive quality control system according to the need of software development life cycle. In other words, we do software right the first time or build quality in the process. On the basis intermediate and final time or build quality in the process. On the basis of data achieved, we can evaluate the products according to the consequences of the data, What are the problems to contrive the software quality control system?, we con promote the quality of products. To achieved that goal, we con provide a suitable the technique and method of software quality control.
