컴퓨터 시뮬레이션을 통해 실제 전투 자산을 가동하지 않고 실전과 같은 전투경험을 부여하기 위해서는 데이터베이스를 포함한 페더레이트(federate)간의 연동(federation)이 네트워크상에서 잘 수행되어야 한다. 이에 본 논문에서는 전장 데이터(이하 액티브 패킷)의 신속한 전달을 필요로 하는 실제상황과 유사한 전장공간을 구축할 수 있도록 액티브 네트워크 상에서 페더레이트(혹은 액티브 노드) 간의 효율적인 트래픽 처리가 가능한 가상 전장 환경을 구성하고, 이에 대한 유효성을 모의 실험을 통하여 검증하였다.

We examine interoperability for integrated training simulation of a mechanized infantry battalion that uses a war game model of Korean army, Combat 21, and virtual simulators of K1 tanks. We discuss issues and problems for integrated simulation of the virtual and constructive models, including differences between the model scopes, model resolutions, engagement algorithms, and data consistency and training audiences of the war game model and virtual simulators. From these, we identify interoperability requirements. We propose ways of resolving the problems using a model converter.

Swarm has recently become a critical component of offensive and defensive systems. Multi-agent reinforcement learning(MARL) empowers swarm systems to handle a wide range of scenarios. However, the main challenge lies in MARL's scalability issue - as the number of agents increases, the performance of the learning decreases. In this study, transfer learning is applied to advanced MARL algorithm to resolve the scalability issue. Validation results show that the training efficiency has significantly improved, reducing computational time by 31 %.

Objective : This study examined changes in the depression, anxiety, and suicidal ideation among Air Force conscripts during their Basic Military Training. Methods : Study participants were 500 Air Force conscripts. The study reviewed participants' self-reports on depression, symptoms of anxiety, and suicidal ideation at weeks 2, 4, and 6 of their training. Results : At weeks 2 and 4 of training, participants' mean BDI, BAI, and SCL-90-R depression and anxiety subscale scores were within the mild ranges. However, at week 6, those mean scores were in the normal ranges. The mean scores for the BDI, the BAI, and the depression and anxiety subscales of the SCL-90-R at weeks 2 and 4 were significantly elevated over the corresponding scores for week 6 (each F=8.78, df=2, p<0.01 ; F=22.16, df=2, p<0.01 ; F=11.08, df=2, p<0.01 ; F=3.42, df=2, p<0.05). Suicidal ideation, revealed by the mean BSIS score, fell within the normal range (F=9.94, df=2, p<0.01) throughout the study period. Conclusions : These results suggest that conscripts' initial levels of psychological distress in the form of depression and anxiety are slightly elevated, but most adapt to this distress during basic training. Therefore, more attention must be paid to the early stages of conscripts' basic training in order to address these concerns.

Today's world is generation of Transformation. The Term "Transformation" is widely used in many nations and international organizations such as U.S. and NATO to describe the course of change undertaken by militaries to respond to the new and emerging security environment. Transformation involves all elements of the defense enterprise including Operational Environment, Operational Concepts, Doctrine, Structure and Technologies, within a supportive Cultures context. An Operational Environment is defined as "a composite of conditions, circumstances, and influences that affect the employment of military forces and bear on the decisions of the unit commander." The context for developing future military concept and capability lies essentially within the anticipated boundaries of the operational environment in a collective sense. The joint operational environment is essential to the nation's defense. It describes volatile, complex, and dangerous environment in which the military personnel. organizations, and material will operate. Implications coming forth from joint Operational Environment are but a starting point - many others exist. More and better Implications will come forth as people think about massages of Operational Environment, experiment its characteristics, learn to deal with its threats and scenarios, apply their experience and judgement, and then consider what is required of Korean military doctrine, organizations, training and education, material development, and leadership for operations in the joint Operational Environment.

국방 분야에서 기존에 구축된 정보시스템은 대부분 대용량의 정보처리 등 단순한 정보처리 중심이었기 때문에 정보의 지적인 수행 능력이나 지식의 표현기술에 대한 능력은 부족한 실정이다. 따라서 기존의 국방정보시스템이 효율적 정보검색 및 관리를 가능케 하는 지능형 국방정보시스템으로 변화되기 위해서는 지식 구축의 핵심이 되는 국방 온톨로지 구축이 필수적이다. 본 논문에서는 6단계 상향식 방법을 이용한 온톨로지 추출 방안을 기술하고, 이를 국방교육훈련 분야에 적용하여 국방 온톨로지 프로토타입을 추출한 후 대표적인 온톨로지 개발 툴인 $Prot\acute{e}g\acute{e}$를 이용하여 구현하였다.

This paper presents the educational methodology shipboard training methods of Maritime Colleges in U.S.A. and the fields of engagement in business of the graduates from them. There are two Maritime Academies, i.e. U.S. Merchant Marine Academy (USMMA) and U.S. Coast Guard Academy, which are supported by federal government and six Maritime Colleges operated by each State. Maritime Administration (MARAD) in the Department of Transportation (DOT) supports the training of merchant marine officers and crew members with a focus on safety in U.S. waterborne commerce. The shipboard training methods are not unique, but have various process. One is continuous sea term training onboard during sophomore (100 days) and junior year (200 days) in case of USMMA, the other is summer sea term training onboard every three months during freshman, sophomore and junior years in case of SUNY Maritime College. They offer also one month ship simulator training ashore. The employment status for the 1999 year graduates from USMMA shows 43 percent in the field of maritime afloat, 34 percent of maritime ashore, 22 percent of active duty military and 1 percent of others.

우리 군도 하루 속히 사이버전에 대비한 정보보호 요원들을 양성하여 우리 사이버 국토가 외국 사이버 전사들에 의한 경유지로 활용되는 것을 차단하고, 유사시 적절히 군을 보호할 수 있는 역량을 강화하여야 할 필요성이 절실해지고 있어서 향후 국방 정보보호 인력 양성을 위하여 고려되어야 할 사항들을 제시한다.

In this thesis, we propose an integrated simulation method of virtual tank simulators and an entity-based constructive simulation model for small unit tactical training. To do this, we first identify requirements for virtual-constructive integrated simulation in a synthetic environment. We then propose a virtual and constructive interoperation method where individual combat entities of virtual-constructive models are interacting with each others. We develop a method of aggregating individual combat entities into a larger combat unit and disaggregating an unit into entities from time to time. We also present a way of sharing synthetic environment information between the models. Finally, we suggest that for more effective interoperability, virtual and constructive models should be developed by using common combat object models. The proposed interoperation method can be extended to further live-virtual-constructive models.
