In this study, we conducted a survival analysis on battalion-level commanders(leaders), focusing on infantry battalion defensive operations using the big data of brigade-level KCTC(Korea Combat Training Center) training results. Unlike previous studies, we utilized the brigade-level KCTC training results data for the first time to conduct a survival analysis, and the research subjects were battalion-level commanders(leaders), which can affect the battle. At this time, the battle results were defined, and through cluster analysis, infantry battalions were divided into excellent, average, and insufficient units, and the difference in the survival rate of the commanders was analyzed through the Kaplan-Meier survival analysis. This provided an opportunity to objectively compare the differences between excellent and insufficient units. Subsequently, factors affecting the survival of commanders were derived using the Cox proportional hazard model, and it was possible to confirm the influencing factors from various angles by also using the survival tree model. Significance and limitations confirmed in the research process were presented as policy suggestions and future research directions.

본 연구는 인공신경망을 이용하여 대대급 방어 작전에서 임의시점에서의 작전지속능력을 예측하는 데 있다. 전투결과에 대한 수학적 모델링은 이를 위한 많은 요인들이 가지는 시?공간적 가변성으로 인해 전투력을 평가하는데 많은 문제점이 있었다. 따라서 이번 연구에서는 대대 전투지휘훈련간 각 부대의 생존률을 전방향 다층 신경망(Feed-Forward Multilayer Perceptrons, MLP)과 일반 회귀신경망(General Regression Neural Network, GRNN)모형에 적용하여 임무달성 여부를 예측하였다. 실험 결과 매개변수들의 비선형적인 관계에도 불구하고 각각 82.62%, 85.48%의 적중률을 보여 일반회귀신경망 모형이 지휘관이 상황을 인식하고 예비대 투입 우선순위 선정 등 실시간 지휘결심을 하는데 도움을 줄 수 있는 방법임을 보여준다.

미래전장에서 대화력전(Counter Fire)의 중요성은 더욱 부각되고 있다. 대화력전은 적 화력자산과 이를 지휘통제하는 모든 요소를 타격하여 적의 화력자산의 능력과 전투지속능력 및 전의를 약화시키는 화력전투를 말한다. 대화력전은 크게 공세적 (Proactive) 대화력전과 대응적(Reactive) 대화력전으로 구분된다. 지금까지의 연구들을 보면 공세적 대화력전의 탐지수단인 UAV(Unmanned Aerial Vehicle:무인항공기)에 대한 운용효과 연구는 지속적으로 발전되고 있지만, 대응적 대화력전 탐지수단인 포병 표적탐지 레이더에 대한 운용효과를 계량적으로 분석한 결과는 없는 실정이다. 이에 본 연구에서는 운용중인 포병 표적탐지 레이더의 운용효과를 C2(Command & Control : 지휘통제)이론과 행위자 기반 시뮬레이션인 MANA(Map Aware Non-uniform Automata)모델을 이용하여 계량적으로 분석 제시함으로써 표적탐지레이더 운용 효과를 구체적으로 보여주었다.

사이버공간은 지상, 해상, 공중, 우주에 이어 다섯 번째 새로운 전쟁 공간으로 자리매김하였고, 군사작전 측면에서도 사이버공간이 핵심적인 공격과 방어 목표가 되고 있다. 세계 각국은 이러한 사이버공간에 대한 공세적 사이버 작전 수행의지를 보인다. 본 논문에서는 기존의 방어적 전략인 사이버 킬체인 모델에 합동 항공임무명령서(ATO)의 임무수행주기와 합동표적처리 절차를 융합한 공세적 개념의 사이버 킬체인 모델을 제안한다. 제안한 모델은 사이버 작전의 합동성 측면에서 물리 작전과 사이버 작전의 통합을 통해 전략적 차원의 국가 사이버 작전 역량 개선에 기여할 것으로 기대한다.

On-off control performance of target pumping station was experimented by changing measurement methods for storage level or inflow and operating logic for control system setting. Four scenarios with different measurement methods and operational logic were examined in the Matlab/Simulink environment. Controller's on-off control repetition that was frequent before has been reduced and more effective and stable system operation was found to be possible with the scenarios. Moreover, defensive operation enforced prevention of floods by changing measurement methods enabled economic operation that made an utmost use of storage volumes.

1. The obesity is the aggregation of symptoms accompanied with the metabolic disorder and the increase of fatty layer accumulation by the enlargement or increase of fatty cells, which is the condition that has 20% overweight than the standard. 2. The final metabolic of fat depends on the defensive energy. The shape of fatty layer is changed by the point where is the defensive energy is replenish or not. So Goin, Bein and Yuckin is made a discriminated and there is different between Besudaeso and Herlgidaso. 3. In case of liver overacting spleen by seven emotions, we can use reinforcing the spleen and don't use depressing energy. 4. Damp, weakness of Qi(氣), weakness of spleen came from seven emotion, and social stress can occur obesity. Obesity is reason of C.V.A, dizziness, dementia, schizophrenia, etc. 5. The obesity which can occurs various adult diseases came from eating disorder and various stresses at the standpoint of western medical. This is cured by diet, kinesiatrics, operation, pharmacotherapy, etc.

Even though the potential for an accident in nuclear power plants is very low, multiple emergency plans are necessary because the impact of such an accident to the public is enormous. One of these emergency plans involves a robotic system for investigating accidents under conditions of high radiation and contaminated air. To develop a robot suitable for operation in a nuclear power plant, we focused on eliminating the three major obstacles that challenge robots in such conditions: the disconnection of radio communication, falling on uneven floors, and loss of localization. To solve the radio problem, a Wi-Fi extender was used in radio shadow areas. To reinforce the walking, we developed two- and four-leg convertible walking, a floor adaptive foot, a roly-poly defensive falling design, and automatic standing recovery after falling methods were developed. To allow the robot to determine its location in the containment building, a bar code landmark reading method was chosen. When a severe accident occurs, this robot will be useful for accident condition monitoring. We also anticipate the robot can serve as a workman aid in a high radiation area during normal operations.

Airpower is a crucial force for suppressing military threats and achieving victory in wars. This study evaluates newly introduced fighter forces, considering factors such as fighter performance and power index, operational environment, capacity of each airbase, survivability, and force sustainment capability to determine the optimal deployment plan that maximizes operational effectiveness and efficiency. Research methods include optimization techniques such as MIP(mixed integer programming), allocation problems, and experimental design. This optimal allocation mathematical model is constructed based on various constraints such as survivability, mission criticality, and aircraft's performance data. The scope of the study focuses the fighter force and their operational radius is limited to major Air Force and joint operations, such as air interdiction, defensive counter-air operations, close air support, maritime operations and so on. This study aims to maximize the operational efficiency and effectiveness of fighter aircraft operations. The results of proposed model through experiments showed that it was for superior to the existing deployment plan in terms of operation and sustainment aspects when considering both wartime and peacetime.

Nowadays, container transport services play a substantial role in global cargo transportation by serving as an intermodal between the exporter and importer. Container shipping has become increasingly important over the past few decades due to its obvious advantages. However, Vietnam's container market has shown severely ongoing competition among numerous domestic and foreign shipping lines resulting in serious consequences occurring such as the freight rates substantially decreasing within the last ten years. In fact, Vietnam's sea lanes have become more defensive to cover the losses of shipping companies. Selection of criteria for competitive evaluation of container transport companies is necessary to help recognize the problems within the enterprise especially relating to its position in the market and from here, business management are able to put strategic plans in place and reasonable policy in order to be able to survive and grow.
