In this study, we improved the layout of deckhouse pre-erection area where erects the blocks and developed the pre-erection block arrangement system for the improvement of productivity and effectiveness. The major operating point of the pre-erection area is to fabricate as many as possible that has restrict area and working plate. The developed system has information management module, scheduling module, schedule control module, statistics module, and information integrate module. The heuristic algorithm is issued and evaluated with real data. And genetic algorithm is used for the evaluation of issued it.

The construction of bored tunnels in soft ground inevitably causes ground movements. In the urban environment these may be of particular significance, because of their influence on buildings, other tunnels and services. The prediction of ground movements and the assessment of the potential effects on the structures is therefore an essential aspect of planning, design and construction of a tunnelling project in the urban environment. In this study, to minimize the effect of tunnelling-Induced ground movements on the adjacent structures, a system for tile settlement risk management was developed. The GIS based risk assessment system for adjacent structures developed in this study consists of several modules such as building information module, settlement evaluation module, potential risk assessment module for adjacent structures, and analysis module for monitoring data. This system focuses on controlling and managing construction processes that may lead to settlement In the surrounding buildings and can contribute to producing the optimum technical and economic design.

Soil erosion has been emphasized as serious environmental problem affecting water quality in the receiving waterbodies. Recently, Best Management Practices (BMPs) have been applied at a field to reduce soil erosion and its effectiveness in soil erosion reduction has been monitored with various methods. Although monitoring at fields/watershed outlets would be accurate way for these ends, it is not possible at some fields/watersheds due to various limitations in direct monitoring. Thus modeling has been suggested as an alternative way to evaluate effects of the BMPs. Most models, which have been used in evaluating hydrology and water quality at a watershed, could not reflect rainfall intensity in runoff generation and soil erosion processes. In addition, source codes of these models are not always public for modification/enhancement. Thus, runoff-sediment evaluation system using hourly rainfall data and vegetated filter strip (VFS) evaluation module at field level were developed using open source MapWindow GIS component in this study. This evaluation system was applied to Bangdongri, Chuncheonsi to evaluate its prediction ability and VFS module in this study. The NSE and $R^2$ values for runoff estimation were 0.86 and 0.91, respectively, and measured and simulated sediment yield were 15.2 kg and 16.5 kg indicating this system, developed in this study, can be used to simulate runoff and sediment yield with acceptable accuracies. Nine VFS scenarios were evaluated for effectiveness of soil erosion reduction. Reduction efficiency of the VFS was high when sediment inflow was small. As shown in this study, this evaluation system can be used for evaluation BMPs with local rainfall intensity and variations considered with ease-of-use GIS interface.

현재 거의 모든 운영체제는 여러 웹 서비스를 지원하기 위하여 운영체제 수준의 보안성을 제공하고 있다. 하지만, 많은 부분에서 운영체제 수준의 보안성이 취약한 것이 사실이다. 특히, TCSEC(Trusted Computer System Evaluation Ceiteria)에서 정의한 B2 레벨 이상의 보안성을 만족시키기 위한 Security Kernel 레벨에서의 감사/추적 기능이 필요하다 이를 위해 시스템 콜 호출시 감사 자료를 생성하고, 모든 이벤트에 대해 동일한 포맷의 감사 자료를 생성하여 추후 역추적 하는데 필요한 정보를 제공토록 한다. 본 논문에서는 안전한 증거 확보를 위하여 기존 리눅스 커널에 대해 변경 없이 적용 가능한 LKM(Loadable Kernel Module) 기법을 이용한 감사/추적 시스템 모듈을 제안하였다. 이는 침입탐지시스템과 같은 외부 감사자료 등을 동시에 활용할 수 있는 인터페이스를 제공하고, 시스템 관리자와 보안 관리자를 구분하여 역할기반의 안전한 시스템을 제공한다. 이러한 자료 등은 추후 법적 대응이 가능한 컴퓨터 포렌식스의 자료로 활용하고자 한다.
