Modern warfare has developed into a network based simultaneous and integrated warfare where operations elements are interconnected. Following such change in modern warfare, ROK Army has been making an effort to transform personnel-based military structure into technology-based advanced structure. Considering technological innovations and changes in characteristics of officers and men, ROK Army is developing scientific education and training system to provide demand-focused customized education. To support such transformation in education and training, ROK Army is constantly developing Army training system using advanced M&S technology. This paper describes ROK Army's education and training policy, and elaborates the current status of M&S training system using advanced M&S technology. This paper further discusses the future directions of M&S training system.

A complex system such as defense systems is in a form of System of Systems (SoS) in which each component is a system being independent of other component systems. Dynamical behavior of SoS is represented by a composition of behaviors of component systems. Thus, a M&S tool/environment would not be efficient for development of heterogeneous models nor for simulation in a centralized environment. Moreover, such an environment restricts reusability and composability. This paper presents an interoperation method for M&S of defense systems as SoS. The approach first develops component system models using tools, each specialized to M&S of each component system. It then interoperates such simulations together to simulate a whole system as SoS. HLA/RTI is employed for such interoperation, which is a DoD/IEEE standard to support interoperation. We will introduce a case study for interoperable simulation of defense systems, which consists of a wargame simulator and a communication simulator.

Global Positioning System(hereafter; GPS) is recently an essential element in the various navigation and weapon delivery systems of military aircraft. However, GPS is vulnerable to the jamming threats since its signal power is very weak. Therefore, ROK defense has been concerning how to resolve this issue and how to integrate these systems needed, and is trying to acquire the proper anti-jamming GPS system. This study is to provide several schemes against the jamming threats effectively. We propose the several processes to analyze the required capability and demonstrate the result's of modeling and simulations(hereafter; M&S) for this integration of military aircraft, and the mathematical programming model for system optimization of military aircraft anti-jamming GPS system on the basis analysis of M&S results which could be considered available budget and the project characteristic. These schemes will be helpful on proper acquisition of these systems and. We are looking forward to contributing to the integration of anti-jamming GPS system of ROK military aircraft.

The purpose of this study was to analyze drainage facilities in mountainous urban neigbborhood parks--Baebongsan Park and Ogeum Park--in Seoul. Based on an analysis of existing drainage facilities, the volume of storm water runoff (VSW), the runoff rate of open channels(ROC), and the detention capacity of open charmels(DCOC) by each drainage watershed, the coefficient of runoff rate(CROC) as evaluated to be relevant between VSW and ROC and the coefficient of the detention capacity of open channe1s(CDCOC) as evaluated with DCOC compared to VSW were estimated and analyzed by parks and by watersheds. The results are as follows: 1. The total drainage area of Baebongsan Park was 34.13ha including surface runoff area(15.05ha; 44.09%), open channel area(l4.60ha; 42.78%), and natural waterway area(4.48ha; 13.13%). The total drainage area of Ogeum Park was 20.39ha including open channel area (10.14ha; 49.73%), ridge-side gutter area(7.17ha; 35.16%), surface runoff area (2.52ha; 12.36%), and natural waterway area (0.56ha; 2.75%). In Baebongsan Park, the portion of surface runoff was comparatively higher while the portion of artificial drainage area was higber in Ogeum Park. 2. In Baebongsan Park drainage districts were largely divided: VSW was $7.28m^3/s$ in total(average $0.23m^3/s$). Comparatively, tbe VSW in Ogeum Park, including smaller drainage districts, was $4.37m^3/s$ in total(average $0.12m^3/s$). 3. The ROC of Baebmgsan Park was $11.58m^3/s$ in total(average $0.77m^3/s$) and the CROC was 5.26, while in Ogeum Park, the ROC was $15.40m^3/s$(average $0.34m^3/s$) and tbe CROC was 8.87 higher than that of Baebongsan Because the size and slope of the open channel in Baebongsan Park was higher, the average ROC was larger, while tbe CROC of Ogeum Park was higher than that of Baebongsan Park, for the VSW in Ogeum Park was comparatively lower. 4. The DCOC in Baebongsan Park was $554.54m^3$ and the average of CDCOC was 179.83. That of Ogeum Park was $717.74m^3$ and the average of the CDCOC was 339.69, meaning that the DCOC of Ogeum Park was so much higber that drainage facilities in Ogeum Park were built intensively. This study was focused m the capacity of the drainage facilities in mountainous urban neighborhood parks by using the CROC to evaluate relevance between VSW and ROC and the CDCOC to evaluate the DCOC as compared with VSW. The devised methodology and coefficient for evaluating drainage facilities in mountainous urban neighborhood parks may he universally applicable through additional study. Further study m sustainable urban drainage systems for retaining rainwater in a reservoir and for enhancing ecological value is required in the near future.

LVC(Live-Virtual-Constructive) training system is drawing attention due to changes in battlefield situation and the development of advanced information and communication technologies. The ROKAF(Republic of Korea Air Force) plans to construct LVC training system capable of scientific training. This paper analyzes the results of V-C interoperability test with three fighter simulators as virtual systems and a theater-level wargame model as a constructive system. The F-15K, KF-16, and FA-50 fighter simulators, which have different interoperable methods, were converted into a standard for simulation interoperability. Using the integrated field environment simulator, the fighter simulators established a mutually interoperable environment. In addition, the Changgong model, which is the representative training model of the Air Force, was converted to the standard for simulation interoperability, and the integrated model was implemented with optimized interoperability performance. Throughput experiments, It was confirmed that the fighter simulators and the war game model of the ROKAF could be interoperable with each other. The results of this study are expected to be a good reference for the future study of the ROKAF LVC training system.

In this paper, we describe the implementation methods and algorithms for the various technologies and devices required for the construction of the engagement HILS(Hardware In the Loop Simulation) in the limited space to simulate the high-speed maneuvering encounter situation of the weapon system in 3-dimensional real world space. Through this research, we have been able to suggest ways to analyze the major design elements of future electronic warfare equipment through experiments simulating actual engagements between various high-speed maneuvering weapons systems and electronic warfare devices in the future battlefield. It was confirmed that the M&S technology could be used to eliminate technical risks, reduce development cost, and shorten development time in the future real system development. The results of this study can be a great assist not only for the field of electronic warfare system research and development, but also for the research & implementation on HILS of various engaging class weapons systems.
