Future warfare is evolving with advanced science and technology, introducing a variety of unmanned and manned combat systems. These systems generate and exchange massive amounts of information, challenging current tactical communication systems as a foundation for future communication infrastructure. To analyze the information distribution capability of the Army TIGER corps, this paper examines four scenarios: standalone ground network operation, integrated network operation, load distribution, and error recovery. Utilizing M&S results, we highlight the potential of a multilayer integrated command and control network, incorporating ground, air, and space networks, to enhance the reliability and stability of the overall communication network.

The M&S community needs an environmental data representation and interchange mechanism which not only satisfies the requirements of today's systems, but can be extended to meet future data sharing needs. This mechanism must allow for the standard representation of, and access to data. It must support databases containing integrated terrain, ocean, atmosphere, and space data. The SEDRIS provides environment data users and producers with a clearly defined interchange specification. In this paper I present the method to extract the data attributes contained in synthetic environment domain using SEDRIS technology and API.

The paper is basically attempted to reveal a possibility of monetary unification and setting an anchor currency in North East Asian economies such as South Korea, China, and Japan. The Cobb-Douglas utility function is tentatively built by a Walrasian economic framework. Korean Won(KRW) is represented for a numeraire in a structural model, and the estimation of a parameter is performed by 2SLS and GARCH-M models. Empirical evidence is found that not only monetary unification itself in this regime seems not to be practicable, but also setting an anchor currency by Chinese Yuan(CNY) or Japanese Yen(JPY) is also inappropriated due to the fact that the estimated parameter is not converged to a unity. Walrasian equilibria are enhanced by the convergence to a unity in the model. It also has to be mentioned that a number of necessary and sufficient conditions should be fulfilled prior to discuss a monetary unification in North East Asian economies. Instead, Asia currency unit(ACU) is more feasible in reality.

Fire scenarios in a space $20.0m\;\times\;4.0m$ floor and 3.0m high were simulated by using computational fluid dynamics program (FDS 4.0.3) to investigate the effect of the combined operation of both sprinkler and vent systems, which are installed for cooling and blocking smoke which propagates beneath the ceiling of a horizontal corridor, on the temperature and smoke density of it. It was shown that the combined operation both sprinkler and vent systems was more effective than each operation for cooling and blocking smoke, the number of operating sprinklers was two because of corner effect of wall, and over-installed sprinklers deteriorated the effect of cooling and blocking smoke. This study showed that the case of two sprinklers and vent flow rate $3.0m^3/s$ in fire scenario was the most effective for cooling and blocking smoke. It was confirmed that the smoke downdrag occurs in operating sprinkler system, and the more smoke droplets produced by increasing fire size, the greater smoke downdrag occurred.

M&S (Modeling & Simulation) based design is widely accepted for the development of the future weapon system with better performance in a cheaper and faster way. Integrated simulation environment (ISE) is needed for the M&S based design. On the ISE, system engineers can not only verify design options but also validate system requirements. In this paper, we propose architectural models of the integrated simulation environment (ISE) which incorporates mission effectiveness M&S (Modeling & Simulation), system performance M&S, the optimization model of integrated performances, digital mockup and virtual prototype. The ISE architectural models may be used to implement the ISE for the development of the future unmanned ground combat vehicle.

현대 사회에서 극심한 스트레스로 고통을 호소하는 사람들이 많아짐에 따라 효과적인 스트레스 측정 시스템의 필요성이 대두되었다. 본 연구에서는 영상 속 인물의 표정과 음성 감성 분석을 통한 통합 스트레스 분석 시스템을 제안한다. 영상 속 인물의 표정과 음성 감성 분석 후 각 감성값에서 스트레스 지수를 도출하고 정량화한다. 표정과 음성 스트레스 지수로 도출된 통합 스트레스 지수가 높을수록 스트레스 강도가 높음을 증명하였다.

In this paper, we suggested the integration between automatic enforcement system and UTIS(Urban Traffic Information System) base station. UTIS base station and automatic enforcement system are different in the height of installation and the type of communication network. UTIS base station is 25 meter high and communicate with center system by optical network. Whereas automatic enforcement system is 6.6 meter high and communicate with center system by rental network. For the purpose of suggesting the efficient method of integration, research was as in the following. We found that the number of integrated system was 1,628 through the present state of analysis and UTIS equipment was satisfied with the required specifications through field testing. Also we suggested the appropriate configuration of the integrated system and analyzed that the cost of the integrated system installment is 1/5 lower than that of the legacy system installment.

It must be possible to assess how combat actions taking place in cyberspace affect the military's major mission systems and weapon systems. In order to analyze the mission impact caused by a cyber attack through cyber M&S, the target mission system and cyber warfare elements must be built as a model and a scenario for simulation must be authored. Many studies related to mission impact analysis due to cyber warfare have been conducted focusing on the United States, and existing studies have authored separate scenarios for physical battlefields and cyber battlefields. It is necessary to build a simulation environment that combines a physical battlefield model and a cyber battlefield model, and be able to integrate and author mission scenarios and cyber attack/defense scenarios. In addition, the physical battlefield and cyber battlefield are different work areas, so authoring two types of scenarios for simulation is very complicated and time-consuming. In this paper, we propose a method of using mission system information to prepare the data needed for scenario authoring in advance and using the pre-worked data to author an integrated scenario. The proposed method is being developed by reflecting it in the design of the scenario authoring tool, and an integrated scenario authoring in the field of counter-fire warfare is being performed to prove the proposed method. In the future, by using a scenario authoring tool that reflects the proposed method, it will be possible to easily author an integrated scenario for mission impact analysis in a short period of time.

인터넷 서비스의 활용이 급속히 확대되어 가고 있는 가운데 점차 인터넷의 서비스 품질을 향상시키기 위한 시도가 활발히 벌어지고 있다. 현재 인터넷은 링크 계층 기술로 LAN과 전용선(혹은 전화선)을 주로 사용하고 있으나 최근 고속의 ATM 링크 기술이 Qos를 보장해주므로 앞으로 인터넷 통합 서비스를 제공하기 위해서 꼭 필요로 하는 기술이기 때문이다. 현재 IETF에서는 멀티미디어 서비스를 제공하기 위한 인터넷 통합 서비스 모델과 자원 예약 프로토콜 ATM망에서 연동하기 위한 시도를 추진하고 있다. 본 고에서는 인터넷 통합서비스를 ATM 망을 통해 제공하기 위한 연구 동향을 IEFT의 표준화 활동을 중심으로 살펴본다.
