In recent years, unmanned underwater vehicles(UUVs) have emerged as viable technical solution for conducting underwater search, surveillance, and clearance operations in support of mine countermeasure missions(MCMs) because of her autonomy and long time endurance capability. It is necessary for UUV for MCM system design to define system specification from various configuration alternatives. This paper introduces a simulation model for mine countermeasure mission effectiveness analysis and presents some simulation results under various tide conditions for validation of the proposed simulation model.

IMT-2000의 6번째 표준 규격인 와이브로의 파일럿 부반송파는 표준 규격에 명시된 위치에 존재한다. 이 때문에 군 전술 통신에 와이브로를 사용하면 파일럿 부반송파의 위치가 노출되어 방해 신호에 취약할 수 있다. 파일럿 부반송파에 대한 방해 신호는 데이터 부반송파에 대한 방해 신호보다 치명적인 오류를 발생시킨다. 이 때문에 군용에서 와이브로를 안정적으로 사용하기 위해서는 주파수 도약방식, 또는 파일럿 부반송파 위치의 암호화 방식등이 필요하다.

High Level Architecture(HLA) is a specification for interoperation among heterogeneous simulators which are executed in a distributed environment. HLA originally allows a number of federates to join in a federation using a single RTI(Run-Time Infrastructure). To interoperate federations without modifying RTI, agent federate, which represents behavior of a federation, can be used. Agent federate can use MOM(Management Object Model) service or agent-user protocol to acquire information of a federation. This paper performs various experiments to measure performance of two architectures. MOM service shows a loss of performance but can be applied without modifying user federates. Experiment results can be used to determine appropriate architecture for interoperation of federations.

The mirror which is considered in designing a MFD is off-axis primary one and its dimension is wide 556mm height 345mm. The MFD(Mirror Fixation Device) load specification is generated for the high resolution mirror. The optical WFEs for unit loads are calculated from mirror sensitivity analysis and they are compared with allocated allowable optical WFE. The parasite load for the MFD is calculated from their comparison. The MFD compliant with the parasite load is designed.

As the size and complexity of software increases, it is important to ensure the quality of software through testing. Many organizations refer to international standards or test process models to improve the quality of software through establishing a systematic test process. However, these standards and process models provide general processes that do not reflect the characteristics of the domain or the organization's test policies and strategies. To establish a test process that reflects the characteristics of the organization, test policies and strategies based on the organization's quality objectives and the organizational and domain characteristics should be reflected. This study proposes specific methods for eliciting activities and information to establish organizational software test policies and strategies that are essential to establishing a test process that reflects the characteristics of the organization and the system.

In order to detect toxic chemical spread on field ground, we developed stand-off Raman spectrometer system which employed a deep UV laser. In this paper, the design and specification of various components in the spectrometer system are described. Some results when the detection system was tested on the outdoor roads are shown, which may help researching stand-off chemical detectors based on Raman spectroscopy.

환경시험은 개발된 제품이 해당 운용환경에서 설계 성능을 발휘하는가를 운용성과 신뢰성 유지 측면에서 수행하고 있다. 항공전자장비에 대한 환경적합성 시험은 주로 개별 부품 단위로 수행되고 있으며 민간용 규격으로서 RTCA DO-160E이 활용되고 있다. 군용 환경규격은 항공분야 뿐만 아니라 전 군수품에 적용하고 있는 MIL-STD-810F 이외에 전자기 환경분야에는 MIL-STD-461E 등이 적용되고 있다. 항공전자장비에 대한 민간용과 군용 환경시험요건을 분석하여 그 연관성을 검토하였으며 특히 전자기 적합성 요건에 대하여 민간과 군용 규격을 비교 분석하여 민군 겸용화의 방향을 제시하고자 한다.

군수제품 생산업체 및 조달업체를 대상으로 국방규격 및 인용표준 규격에 대한 활용실태와 내용에 대한 유효화(최신화) 확인 방식에 대한 설문조사를 실시하였다. 각 업체별로 보유 또는 활용하고 있는 표준 규격 수를 살펴보면, KS, 국방규격, 미국 군사규격의 순으로 많이 보유하였으며, KS 구입을 위해서는 연간 40만원을, 해외 표준 규격 구입을 위해서 연간 133만원을 지불하는 것으로 조사되었다. 한편, 해외 표준 규격은 언어적인 문제, 정보 접근방식의 모호성, 표준 관련기관의 부재 등으로 인해 KS나 국방규격에 비해 상대적으로 수동적으로 최신 정보를 얻고 있었다. 또한, 설문대상 업체에서는 국방규격 정비(인용규격 최신화 및 KS 부합화) 및 관련 DB 검색 서비스 제공에 대한 요구도가 매우 높아, 보다 효과적인 국방규격 통합 관리시스템 마련이 시급한 것으로 조사되었다.

Rapid turning and accelerated movement of a rotorcraft leads to the slosh and vibration effect of fuel in the fuel tank. Due to the slosh load, the internal component of a fuel tank can be broken and fuel tank skin can be damaged. This is directly related to human survivability. Military specification(MIL-DTL-27422D) requires the verification of the stability of aircraft fuel tank and internal component against slosh & vibration load through the qualification test. This report shows the establishment of slosh and vibration test facility and KUH fuel tank qualification test result.

As the 21st century signifies an information-oriented society, the computer integration takes place in all walks of human presence. Needs for computer and network-integrated automation present new challenges in military as well as commercial facility systems engineering. Since the first intelligent building appeared in USA in 1984, it gradually became an essential capability for the building industry requirement these days. Intelligent Building System(IBS) is evolving to be very complex because there are many subsystems such as telecommunication(TC), office automation(OA), building automation(BA), security, construction environments, etc. During the planing phase of IBS development, therefore, a disciplined systems engineering must be performed to analyze stake- holder's requirements to build an optimized system while minimizing trial-and-error expenses and risks. This paper presents a conceptual design of BAS applying systems engineering methods. The contribution of this study includes the development of IBS subsystem specification for building automation subsystem, which is a part of IBS, using the methodology of requirement analysis, functional analysis, synthesis, and verification. A computer-aided systems engineering s/w, RDD-100, was used to improve the system design efficiency and to promote the product design knowledge management for reuse in later design programs.
