현대 군사 환경에서 병력 보충 방식은 부대의 전투력 유지와 직접적인 연관이 있으며, 한국군의 경우 기존의 개인보충 방식이 부대 응집력 저하 및 전투력 약화의 원인으로 작용하고 있다. 특히, 2021년 12월 병 복무기간이 18개월로 단축된 이후, 개인보충 방식이 과거와 동일하게 유지되면서 연간 병력 교체율이 66%를 상회하게 되었으며, 이로 인해 부대의 전투 효율성 유지가 더욱 어려워지고 있다. 또한, 현재 동원 부대의 편성 방식 역시 개별 동원지정을 기반으로 하고 있어 부대 고정율이 낮고, 짧은 동원훈련 기간으로 인해 유사시 신속한 전투력 발휘에 한계가 존재한다. 이에 따라, 기존 개인보충 방식의 한계를 극복할 수 있는 새로운 병력 보충 방식의 도입이 필요하다. 본 연구는 한국군의 현역 및 동원전력 보충 방안으로 ‘중대단위 부대보충’ 개념을 제안하고, 이를 통해 전투력 유지 및 응집력 강화를 도모하는 방안을 모색하였다. 이를 위해 독일, 이스라엘, 미국 등의 부대보 충 사례를 분석하고, 이를 한국군에 적용할 수 있는 정책적 시사점을 도출하였다. 또한, 부대보충 방식이 부대의 전투력과 조직 응집력에 미치는 영향을 실증적으로 분석하기 위해 전투력 평가 실험을 설계하고, 경제적 타당성 분석을 수행하였다. 분석 결과, 중대단위 부대보충 방식은 병력 운영의 안정성을 높이고, 장기적으로 전투력 유지 및 국가 방위력 강화에 기여할 수 있는 것으로 평가되었다. 본 연구는 한국군의 병력 보충 방식에 대한 새로운 접근법을 제시하고, 부대보충 방식이 기존 개인보충 방식에 비해 효과적인 대안이 될 수 있음을 실증적으로 검토하였다. 이를 통해, 향후 군사정책 수립 및 동원체제 개편에 있어 중요한 자료로 활용될 수 있을 것으로 기대된다.

This study proposes a mathematical model to optimize the fighter aircraft-weapon combinations for the ROKAF(Republic Of Korea Air Force). With the recent emergence of the population declining issue in Republic of Korea, there is an urgent need for efficient weapon system operations in light of decreasing military personnel. In order to solve these issues, we consider to reduce the workload of pilots and maintenance personnel by operating an optimal number of weapons instead of deploying all possible armaments for each aircraft type. To achieve this, various factors for optimizing the fighter-weapon combinations were identified and quantified. A model was then constructed using goal programming, with the objective functions based on the compatibility, CEP(Circular Error Probable), and fire range of the weapons, along with the planned wartime mission-specific weapon ratios for each aircraft type. The experimental result's analysis of the proposed model indicate a significant increase in mission performance efficiency compared to the existing system in both operational and maintenance aspects. We hope that our model will be reflected to help improve the operational capabilities of Republic of Korea Air Force.

The condensation phenomenon can affect the product in terms of function and aesthetics, so it is a complaint of many users from the past, and continuous research has been conducted to solve it. A portable instrument panel is installed inside combat vehicles such as tanks and armored vehicles. Due to the nature of the combat vehicle operated in the special situation of battle, the internal heat generation of the instrument panel has increased significantly, which is presumed to be the cause of condensation inside the instrument panel. In this paper, a study on the development of subsequent processes was conducted to reduce the condensation phenomenon of the instrument panel for combat vehicles. In order to reduce the condensation phenomenon, the experiment was carried out by setting baking time and stabilization time as major factors. This paper is considered to be a reference research data for all systems in which similar assemblies are used as well as instrument panels for combat vehicles.

In this article, improvement of heat screen failure for battle tank is proposed. The heat screen applied to protect a cam sensor from engine heat was cracked by vibrations generated in the engine. To solve this problem, the configuration of the heat screen was changed to a structure that can avoid engine vibration levels. The improved heat screen has first mode frequency at 4,000 RPM band outside the main operating range of the engine, and heat dissipation is at the same level as conventional heat screen. As a result, the improved heat screen secured reliability by improving vibration effects by approximately 163% while maintaining heat dissipation performance.

This paper proposes the armored combat bulldozer, essential for amphibious tasks, requires water ingress prevention and submersion capabilities, typically addressed by a centrifugal pump. This study aims to boost the bulldozer's drainage pump efficiency by replacing the traditional aluminum 3-blade impeller with one made of ASA material using 3D printing. Analysis via ANSYS Fluent revealed that the 5-blade impeller increased discharge volume by 19.31% and efficiency by 6.07%, while the 6-blade variant saw a 27.07% increase in discharge volume and 8.81% efficiency improvement. Further scrutiny with ANSYS Static Structure ensured the new impellers' structural integrity and robustness under extreme conditions. This research confirms the potential of 3D printing in enhancing military equipment, demonstrating significant improvements in pump performance and opening paths for advanced manufacturing techniques to meet the demanding needs of combat vehicles.

This study addresses the optimal design methodology for switching between active electronically scanned array (AESA) radar operating modes to easily select the necessary information to reduce pilots' cognitive load and physical workload in situations where diverse and complex information is continuously provided. This study presents a procedure for defining a hidden Markov chain model (HMM) for modeling operating mode changes based on time series data on the operating modes of the AESA radar used by pilots while performing mission scenarios with inherent uncertainty. Furthermore, based on a transition probability matrix (TPM) of the HMM, this study presents a mathematical programming model for proposing the optimal structural design of AESA radar operating modes considering the manipulation method of a hands on throttle-and-stick (HOTAS). Fighter pilots select and activate the menu key for an AESA radar operation mode by manipulating the HOTAS’s rotary and toggle controllers. Therefore, this study presents an optimization problem to propose the optimal structural design of the menu keys so that the pilot can easily change the menu keys to suit the operational environment.

In the (3,3) close combat model based on the Lanchester Square Law, this study proposes a plan to optimally allocate residual combat power after the battle to other battlefields. As soon as the two camps of three units can grasp each other's information and predict the battle pattern immediately after the battle began, the Time Zero Allocation of Force (TZAF) scenario was used to initially allocate combat power to readjust the combat model. It reflects travel time, which is a "field friction" in which physical distance exists from battlefields that support combat power to battlefields that are supported. By developing existing studies that try to examine the effect of travel time on the battlefield through the combat model, this study forms a (3,3) combat model, which is a large number of minimum units. In order to achieve the combat purpose, the principle of optimal combat force operation is presented by examining the aspect that support combat power is allocated to the two battlefields and the consequent battle results. Through this, various scenarios were set in consideration of the travel time and the situation of the units, and differentiated results were obtained. Although the most traditional, it can be used as the basic logic of the training or the commander's decision-making system using the actual war game model.

In this study, the abnormal noise phenomenon generated intermittently in the shock absorber of the combat armored vehicle was approached from the side of the squeak joint to solve the phenomenon. In order to identify the cause of the noise, the factors causing friction in the shock absorber were checked from the viewpoint of problem product analysis, process, and design. As an improvement plan, by improving the non-lubricated section in the nitrogen chamber, the operating noise was reduced to a level lower than that of a general automobile engine along with the elimination of noise. Considering that this is a combat vehicle, it is judged that it has been improved so as not to affect the survivability and health of the crew during equipment operation. Through the improvement of this study, it is expected to prevent power loss and improve the emotional quality of our soldier.

Combat-armored vehicles were equipped with an automatic-fire-extinguishing system to ensure the safety of the crew and vehicle from fires on the vehicle. When a fire was occurred, the automatic-fire-extinguishing system automatically detects the fire through sensors and detection lines, sprays a fire extinguisher, and notifies the crew visually and audibly. Recently, there had been cases of automatic-fire-extinguishing systems malfunction on combat-armored vehicles. In this study, in order to resolve the automatic-fire-extinguisher's malfunction phenomenon, ground noise and inter-circuit noise generated from the fire detection line were identified, and the resistance connected on the circuit was revised to remove noise. As a result of resistance revision, the noises was eliminated and the electromotive force difference between input circuits was made constant, thereby improving the malfunction of the automatic-fire-extinguishing system. By applying the result, it was confirmed that the control device sensed a temperature similar to the actual temperature on actual vehicles, and it was confirmed that the automatic-fire-extinguishing system's malfunction phenomenon was not founded in the field vehicles after then.

A universal joint is a device that transmits the power of a combat vehicle engine to a cooling fan. The power of the engine is transmitted to the universal joint as it is without buffering, and play occurs at the joint between the drive shaft connected to the engine and the driven shaft connected to the cooling fan according to the usage time. Accordingly, the universal joint is periodically replaced, and the criterion for this is the degree of torsion of the universal joint. However, if the universal joint is not properly maintained during the replacement cycle, damage to the universal joint as well as damage to the surrounding power supply may occur. Accordingly, a backlash measuring device was developed to determine the limit of durability of the universal joint, and the limit of durability was derived through regression analysis of the backlash value according to the use time obtained from the accelerated life test.

The paint removal of fighter jets is just as important as the painting, because perfect paint removal ensures the quality of the exterior painting on the aircraft. However, the current conditions for paint removal work of the ROKAF’s are poor. It is identified that the painting process currently implemented by the ROKAF is not only exposed to harmful compounds such as harmful dust and hexavalent chromium, but also consumes a lot of water. Thus, the introduction of advanced facility is considered. This study compares the fighter jets painting removal process currently applied by the Korean Air Force with the improved laser coating removal process of the US Air Force, and conducts an incremental analysis to perform economic analysis for the introduction of advanced facility. Four scenarios were envisioned on the premise of an increase in the number of fighters in the future, incremental analysis shows that laser coating removal method is advantageous in all scenarios. In addition, it is recommended that paint removal cycle keeps the current 12-year and the outsourcing amount to civilian depot is reduced.

현시대에도 동아시아 세계에서 국가 간 이익을 위해 합종연횡이 수시로 이루어지고 있다. 역사적으로도 한반도에서 6.25를 제외한 국제전이 3번에 걸쳐 발생한바, 서기 663년의 백촌강 전투, 1592년의 왜와 조선・명나라 의 임진왜란, 1894년의 청일전쟁이 있었다. 위에 열거한 전쟁중 7세기 중 엽 한반도에서 벌어졌던 백촌강1) 전투는 신라와 당의 연합군과 백제부흥 군과 왜의 동맹군이 싸운 전쟁으로서 라당 연합군의 승리와 백제부흥군과 왜군이 참패한 전투이다. 6세기 수나라가 중국을 통일하여 동아시아의 국 제사회는 큰 변화에 직면하게 되었다. 이러한 역사적 변화에 따른 한반도 에서도 삼국 간의 세력균형이 깨지고 적자생존과 영토 및 세력 확대를 위 해 국제적으로 합종연횡이 가속화되었다. 백촌강 전투는 이와 같은 역사적 배경으로 전개된 국제전으로서, 전투의 영향은 동아시아 국제사회를 흔들 고, 역사의 새로운 전환점을 마련했다. 본 연구는 백촌강 전투 전후 당의 동아시아에 대한 대외정책은 어떤 것이 있었으며, 전투 후 대외정책은 어 떻게 변화하였으며, 그에 따라 동아시아 각국은 어떻게 대응하였는지를 알 아보고자 한다.
