본 논문의 목적은 군사 측면에서 러시아의 생각과 논리를 정확히 읽기 위해 러시아 군사전략의 본질을 규명하는 것이다. 이에 따라 러시아 군사전략 구성요소 중 러시아의 위협인식이 무엇인지 파악하고 그러한 위협에 대응하기 위해 어떻게 군사력을 건설했으며, 유사시에는 어떻게 사용했는지 고찰했다. 러시아 위협인식은 첫째, 크림 합병 이후 더욱 강화된 외국의 대러 압박을 중요한 위협으로 보고 있으며, 이는 강대국 정체성 유지와 관련된다. 둘째, 러시아는 미국 및 NATO를 지대한 위협으로 보고 있으며, 이는 전략균형 유지와 관련된다. 셋째, 미국의 MD, 우주공간 무기화, 글로벌신속타격(PGS) 개념의 현실화는 러시아의 미래전 대비와 관련된 위협이다. 러시아는 위협에 대비하기 위해 병력 충원, 무기 현대화, 주요 전략방향 전투준비, 실전적 훈련 등으로 군사력을 증강하였다. 또한, 크림반도 합병, 시리아 대테러작전 개입 간 실제 군사력 운용 사례를 분석한 결과 강대국 정체성, 전략균형, 미래전 대비 등 3개 요인이 작용한 것을 알 수 있었다. 이와 같은 러시아 군사전략을 고려하여 한국의 군사안보를 위해 전쟁억제 방법, 위협 대응 위주 군사력 건설, 군사협력 확대 방안을 발전시킬 필요가 있다. The purpose of this study is to find out the essence of Russia's military strategy in order to accurately read Russia's ideas and logic in the military affairs. In this study the author examined how russian military forces were built and used to respond to such threats in times of emergency. Russia, first of all, considers stronger foreign pressure on Russia since the introduction of Crimea to be a major threat, which is related to maintaining the identity of a superpower. Secondly, Russia regards the United States and NATO as the greatest threats and this will involve maintaining a strategic balance. Third, the U.S. MD, the weaponization of outer space, and the realization of the concept ‘Prompt Global Strike(PGS)’ pose a threat to Russia's future war rediness. To prepare for the threats, Russia has stepped up its military strength by replenishing its forces, modernizing its weapons, preparing for war in key strategic directions, and conducting practical training. In addition, the analysis of actual military operations involving the merger of the Crimean Peninsula and the intervention of the Syrian counterterrorism operation showed that three factos were working such as identity of the superpower, the balance of strategy, and the preparation for a future war. Considering Russia's military strategy, South Korea needs to develop ways to deter war, build military forces centered on threats, and expand military cooperation with Russia to ensure military security.

최근 일본은 인도-태평양 전략을 토대로 미일 동맹을 강화하는 한편, 집단적 자위권 행사 용인과 해병대와 항모 전력 배비 등 새로운 군사전략을 추진하면서 보통국가 행보를 지속하고 있다. 이러한 움직임은 일대일로 구상을 통해 역내 패권을 추구하는 중국의 군사력 증강과 해양진출, 북한의 핵 및 미사일 발사 등 군사적 위협 증대와 맞물리며 역내 군비경쟁을 가속화시키고 있다. 일본은 전후 냉전 해체 등 급변하는 국내외 안보환경 변화 가운데 「적극적 평화주의」를 내세우면서, 미일 동맹을 중심으로 보통국가를 적극 추진하고 있다. 지난 1960년 미일 상호안보조약을 체결하고, 미일 동맹에 의존하는 국가안보를 추진해 왔던 일본은 1976년 방위계획대강과 1978년 미일 가이드라인을 채택한다. 이후 방위계획대강은 2018년 5번째, 미일 가이드라인은 2015년 2번째 개정하고, 2013년 국가안보전략을 발표하며 국가안보체계를 갖춘다. 이러한 관점에서 본다면 일본의 군사전략은 안정된 미일 동맹을 토대로 일관성을 유지하면서도, 정세변화 등 다양한 변화를 반영하여 발전되어 왔다. 일본의 군사전략 분석을 위해 ① 국가안보전략 차원에서 방위계획대강과 미일 가이드라인, 안보법제, 미일 인도-태평양 전략 ② 자위대의 편성과 배치, 방위비 운용, 육해공 전력평가, 방위산업 측면을 대상으로 분석하였다. 도출된 일본의 군사전략은 ① 미일 일체화 전략 ② 미래 선점 군사전략 ③ 독자적 원거리 전력투사가 가능한 자기완결 군사전략 ④ 동맹 네트웍 군사전략 ⑤ 다차원 통합 군사전략이며, 향후 전망과 과제로서 ① 미중 관계의 변화 ② 동북아 군비경쟁의 가속화 ③ 일본 국민들의 안보의식 변화 ④ 한반도 통일 한국의 가능성이다. 결론적으로 우리의 대응을 한일 및 한미일 안보협력 관점에서 제시한다면 ① 한미 동맹 차원에서 한미일 안보협력을 적극 추진 ② 한반도 유사 억제와 대처를 위한 실효적 한일 및 한미일 안보협력 추진 ③ 한일 국방장관 상호방문 등 협력증진 추진 ④ 유엔을 비롯한 우방국과의 연합작전 능력 확대 ⑤ 한일 국민적 공감대 확산이다. 한일 관계는 만들어 지는 것이 아니라 만들어 나가는 것이다. 전쟁은 준비하는 자에게만 승리를 보장한다. 최근 동북아 지역 내 군사적 긴장 고조와 불확실성이 우려되는 상황 가운데 위기를 기회로 만들기 위해 일본 군사전략 분석이 한일은 물론 한미일 안보협력 개선 노력에 도움이 될 수 있기를 기대한다. In recent years, Japan has continued its normal state by strengthening the US-Japan alliance based on the Indo-Pacific strategy, while promoting new military strategies such as concession of collective self-defense rights, and the distribution of marine Corps and aircraft carrier forces. These activities accelerate the arms race in the region, coupled with increased military threats such as China's 「one belt-one road」 for pursuit of regional hegemony and sea-going North Korean nuclear and missile launches. Japan is actively pursuing normal nations based on the USJapan alliance, with [active pacifism] among the rapidly changing domestic and international security environments, such as the dissolution of the Cold War. Japan, which signed the US-Japan Security Treaty in 1960, and has pursued national security that relies on the US-Japan alliance, adopts the 1976 National Defense Prom Guideline, and the 1978 US-Japan guidelines. Afterwards, the defense plan outline was revised five times in 2018, and the USJapan guideline was revised two times in 2015, and 2013 announced a national security strategy and equipped with a national security system. From this point of view, Japan's military strategy has been developed to reflect various changes, including changes in the situation, while maintaining consistency based on a stable USJapan alliance. To analyze Japan's military strategy 1) At the national security strategy level, defense plan outline, US-Japan guideline, security legislation, Japan-India-Pacific strategy. 2) Performance Deployment of Self-Defense Forces Defense Cost Management Analysis of the defense industry by land and air power evaluation. Japan's military strategy was: 1) US-Japan unification strategy; 2) future-first military strategy; 3) self-contained military strategy capable of independent remote power projection; 4) alliance network military strategy; 5) multidimensional integrated military strategy. The future prospects and challenges are: 1) changes in USChina relations, 2) accelerated arms competition in Northeast Asia, 3) changes in security awareness among Japanese people, and 4) the possibility of Korean Peninsula unification. In conclusion, if we present our response from the perspective of Korea-Japan and Korea-US-Japan security cooperation, 1) actively promote Korea-US security cooperation at the ROK-US alliance level. 2) Promote effective Korea-Japan and Korea-USJapan security cooperation in order to suppress and cope with the Korean peninsula. 3) Promote cooperation, including mutual visits by the defense ministers. 4) Expanding capacity for allied operations with the United Nations and other allies. 5) Korea-Japan national consensus spreads Korean-Japanese relations are not just created, but to be created. War guarantees victory only to those who prepare. It is hoped that the analysis of Japan's military strategy will help not only the perspective of Korea and Japan but also Korea-US-Japan security cooperation actually improve their relations in order to turn the crisis into an opportunity amid rising military tensions and uncertainties in Northeast Asia.

Stealth technology of combat aircraft is most significant capability in recent air battlefield. As the detector of IR missiles is being developed, IR stealth capability which is evaluated by IR signature level become more important than it was in previous generation. Among IR signature of aircraft from various sources, aerodynamic heating dominates in long-wavelength IR spectrum of $8{\sim}12{\mu}m$. Skin temperature change by aerodynamic heating which is derived by effects of Mach number and structure. The 4th and 5th generation aircraft are selected for calculation of the skin temperature, and its height and velocity in numerical conditions are 10,000 m and Ma 0.9~1.9 respectively. Aircraft skin temperature is calculated by computing convection of fluid and conduction, convection and radiation of surface. As the aircraft accelerates to higher Mach number, maximum skin temperature increases more rapidly than average temperature and temperature distribution changes in more sharp, interactive ways. The 4th generation aircraft whose shape is more complex than that of the 5th generation aircraft have complicated temperature distribution. On the other hand, the 5th generation aircraft whose shape is relatively simple shows plain temperature distribution and lower skin temperature in terms of both average and maximum value.

The silencer for the medium caliber gun was studied to reduce the propagation of gun-generated noise from the firing test range to the community. Three types of silencer were made to compare the reduction of sound pressure level and the effect of chamber volume and the exit angle to the reduction of sound pressure was considered. The structural analysis and measurement of pressure in the silencer showed that the structure is safe in terms of strength. The increase of recoil force to buffer must be considered in the development of silencer. The hypothesis test on the muzzle velocity for the existence of silencer showed that there are no difference at the significance level of 0.05.

For decades, modeling of pilots has been intensively studied due to its advantages in reducing costs for training and enhancing safety of pilots. In particular, research for modeling of pilots' non-kinetic behaviors which refer to the decisions made by pilots is beneficial as the expertise of pilots can be inherent in the models. With the recent growth in the amount of combat logs accumulated, employing statistical learning methods for the modeling becomes possible. However, the combat logs consist of heterogeneous data that are not only continuous or discrete but also sequence independent or dependent, making it difficult to directly applying the learning methods without modifications. Therefore, in this paper, we present a kernel function named hybrid sequence kernel which addresses the problem by using multiple kernel learning methods. Based on the empirical experiments by using combat logs obtained from a simulator, the proposed kernel showed satisfactory results.

EO GRD(Ground Resolved Distance) resolution of airborne EO/IR(Electro-Optical/Infrared) sensor is a critical factor in test and evaluation for EO sensor performance. We propose the laboratory measurement set-up for EO GRD by constructing optical collimator which includes integrated sphere, blackbody, equivalent 3-bar target and 6 DOF motion simulator. GRD is measured in the photographic imagery of bar targets by 3 different distances for 3 EO/IR sensors and the measured results were analyzed statistically. We found that at least 7 sheets of imagery are needed in order to obtain meaningful EO GRD. The result of statistical analysis shows that the distribution of the measured GRD is nearly symmetric about the average GRD, and the better imagery ratio above the average GRD is about 40~70%. Also from the best GRD analysis, it is estimated that the design goal for EO GRD should be 30% superior to the required GRD.

This paper considers a distributed telemetry system using retransmission algorithm with one master telemetry and two slave telemetries. The master telemetry merges data from each slave telemetry and own measured data. If there exist some errors in data from the slave telemetry, the master telemetry requests retransmission to corresponding slave telemetry. In this paper, we propose a retransmission algorithm applied to implementing the distributed telemetry system. Simulation results demonstrate that the retransmission improves the performance of the communication between the master and slave telemetries.

In this paper, This study shows the content on the impact fuze test and the measurement using underwater explosion phenomena. The impact fuze has both a delay function and a super quick. Up to now, nothing but the naked eye of the observer has been used to verify performance of the impact fuze. The observer has determined the performance by the shape of the plume created from the explosion phenomenon. However, it is extremely difficult to use that method at a long range. In order to solve the problem, the measurement using the underwater explosion phenomena was tried.
