K9 BTCS의 성공적인 개발은 디지털화된 사격지휘 전산장비체계로 종심지원작전, 근접지원작전 그리고 대화력전을 수행하는 여건을 제공하였다. 또한 K9 자주포의 전술적운용 능력과 실시간 타격전력 발휘에 질적인 발전과 변화를 가져다 주었으며, 기존의 BTCS를 기반으로 하여 화력지원 사격지휘체계를 한 단계 높은 화력을 운용하도록 성능개량한 것으로, 무선에 의한 디지털 다중임무수행, 표적획득체계와의 연동운용, 상황도시 등을 윈도우 환경에서 운용할 수 있게 되었다. 이로써 $C^4I$체계상에서 SHOOT & SCOOT 전술적 운용과 효과중심의 탄약을 적시에 사용할 수 있게 하였고, 화력집중과 분산을 용이하게 하였다.

This study is proposed traffic signal operating system to find existing problems of loop system and complex with doplar system, which have strong linearity, resistence of weather effects and wide range to improve delay problems that used in vehicle detection method. This proposed method have simulated on Southern-Gwangju station to Enter of SeoChang take about 10km by using VISSIM tool and we found this proposed method is 15% through(또는 to) 30% more effective than continuous progress interlocking system or crossing progress interlocking system.

The numbering plan, basic requirements for interworking standards, and technical standard specification for National Information Infrastructure have not been defined specifically yet. It is reviewed for the numbering plans of public/private ATM networks based on the standard specifications of W-T and ATM Forum. The specifications for numbering plan are discussed for the interworking between current various networks and National Information Infrastructure based on the related standard specification of ITU-T and ATM Forum.

The rapid growth of network technology makes the high-tech weapon. Thus, in the modern war, the ability to immediately use of the high-tech weapon is important. To realize this ability, continuous trainning is necessary but, this trainning spends many money. To improve the budget efficiency, Modeling and Simulation(M&S) are used. However, they seriously decrease the reality. Recently, the system which can support the combination of Live with Virtual simulation is on the rise. The typical example is L-V-C Environment and many kind of middleware which can support the L-V-C Envrionment are already proposed. Previous middleware can support the interoperability between different simulations but, it cannot completely interoperate three(Live, Virtual, Constructive) simulation environments. In this paper, to solve this problem, we propose the scheme which is combination between different middlewares. And we conduct the API mapping between HLA and DDS which are typical middleware and verify the scheme.

LVC(live-virtual-constructive) integrated training system is a representative cyber-physical system. Each systems in a LVC system has different time domain, resolution and operation methods. So, it is very important to integrate different middlewares as a common middleware for heterogeneous systems using inter-working GWs. Especially, since the LVC system uses different time, it is necessary to study the method for guaranteeing causality and time synchronization among the events from different systems. In this study, we propose an time synchronization scheme to integrate the virtual and constructive system which use the simulation time of HLA (High Level Architecture)/ RTI (Run Time Infrastructure) into the live system based on the OMG DDS (Data Distribution Service). We propose a precise time synchronization scheme based on HLA time management and clock federate between participants and federates which are the communication objects of DDS and HLA/RTI respectively. In addition, we verified that time is well-synchronized among heterogeneous systems using the suggested scheme by implementing and demonstrating simulation applications on each middleware.

본 논문에서는 CORBA(Common Object Request Architecture)기반의 TINA(Telecommunications Information Networking Architecture) 분산체계에서 통신망 하부 장비들이 SNMP(Simple Network Management Protocol) 혹은 TMN(Telecommunications Management Network) 체계로 혼재되어 관리되는 네트워크의 NE(Network Element)들을 효율적으로 통합 관리할 수 있는 Generic Interface Adaptor(GIA)를 제안하고 이를 설계 및 구현하였다. GIA는 message mapping, protocol conversion 및 DBMS를 이용한 Object Abstract Translation(OAT)을 통해서 각 관리체계에 맞도록 관리정보를 변환시키며, 이를 통해 TINA EML(Element Management Layer) component와 SNMP NE agent 간의 상호연동을 가능하게 한다.

21세기 정보화 사회에서 국가 경쟁력의 측정은 정보처리, 운영능력에 달려있다. 이를 대비하여 국가에서는 초고속정보통신망의 구축과 지리정보체계의 구축 등 정보화 사업에 박차를 가하고 있다. 이들 사업은 단위사업이 아닌 국가 기반구조의 구축이라는 중요한 명분을 가지고 있으며 따라서 시스템의 상호운용성, 연동성 등 국가가 지원하여야 할 기본기술은 초고속정보통신망에서 운영될 수 있도록 준비되어야 할 것이다.
