권태환 ( Kwon Tae Whan ) 한국군사학회 2020 군사논단 Vol.100 No.1

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.

러시아의 군사전략: 위협 인식과 군사력 건설 동향

김규철 ( Kyuchul Kim ) 한국군사학회 2020 군사논단 Vol.100 No.1

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.

The hydrogen(H2) is promising energy carrier of renewable energy in the microgrid system such as small village and military base due to its high energy density, pure emission and convenient transportation. H2 can be generated by photocatalytic water splitting, gasification of biomass and water electrolysis driven by solar cell or wind turbine. Solid oxide electrolysis cells(SOECs) are the most efficient way to mass production due to high operating temperature improving the electrode kinetics and reducing the electrolyte resistance. The SOECs are consist of nickel-yttria stabilized zirconia(NiO-YSZ) fuel electrode / YSZ electrolyte / lanthanum strontium manganite-YSZ(LSM-YSZ) air electrode due to similarity to Solid Oxide Fuel Cells(SOFCs). The Ni-YSZ most widely used fuel electrode shows several problems at SOEC mode such as degradation of the fuel electrode because of Ni particle’s redox reaction and agglomeration. Therefore Ni-YSZ need to be replaced to an alternative fuel electrode material. In this study, We studied on the Double perovskite PrBrMnO5+δ(PBMO) due to its high electric conductivity, catalytic activity and electrochemical stability. PBMO was impregnated into the scaffold electrolyte La0.8Sr0.2Ga0.85Mg0.15O3-δ(LSGM) to be synthesized at low temperature for avoiding secondary phase generated when it exposed to high temperature. The Half cell test was conducted at SOECs and SOFCs modes.

In this paper, we designed the transparent circuit analog radar absorbing structure using printed metal grid mesh for enhanced optical transmittance. To obtain wideband electromagnetic absorption and enhanced optical transparency at X-band, we proposed the resistive FSS(Frequency Selective Surface) using printed metal mesh pattern on transparent glass with PEC(Perfect Electric Conductor) plane using ITO(Indium Thin Oxide) coating. We then fabricated the proposed structure to verify the simulation results obtained from commercial EM simulator. The comparisons between the simulation and measured results show good agreements. The results also show that the proposed radar absorbing structure can provide wideband reflection as well as better optical transparency. We can apply this proposed structure to the canopy of stealth aircraft and other stealth and security applications for visible transparency.

This paper shows accuracy comparison results of reliability estimation methods for one-shot systems such as ammunitions. Quantal-response data, following a binomial distribution at each sampling time, characterizes lifetimes of one-shot systems. Various quantal-response data of different sample sizes are simulated using lifetime data randomly sampled from assumed weibull distributions with different shape parameters but the identical scale parameter in this paper. Then, reliability estimation methods in open literature are applied to the simulated quantal-response data to estimate true reliability over time. Rankings in estimation accuracy for different sample sizes are determined using t-test of SSE. Furthermore, MSE at each time, including both bias and variance of estimated reliability metrics for each method are analyzed to investigate how much both bias and variance contribute the SSE. From the MSE analysis, MSE provides reliability estimation trend for each method. Parametric estimation method provides more accurate reliability estimation results than the other methods for most of sample sizes.

Accurate extraction of traversable region is a critical issue for autonomous navigation of unmanned ground vehicle(UGV). This paper introduces enhanced extraction of traversable region by combining scene clustering with 3D world modeling using CCD(Charge-Coupled Device)/IR(Infra Red) image. Scene clustering is developed with K-means algorithm based on CCD and IR image. 3D world modeling is developed by fusing CCD and IR stereo image. Enhanced extraction of traversable regions is obtained by combining feature of extraction with a clustering method and a geometric characteristic of terrain derived by 3D world modeling.

Plastic bonded explosive(PBX) is mainly composed of the nitramine explosives, RDX, HMX, and polymer binders. When the adhesion between nitramine crystals and binder is not particularly strong and can be failed under stress, dewetting occurs rather suddenly and this leads to a significant drop in tensile strength of explosives. Mechnical property of plastic bonded explosive depends on the surface characteristics of filler and binder. In order to design for better adhesion, an understanding of the surface properties of explosive and binder is essential. In this study, 2 kinds of RDX and 4 kinds of ethylene vinyl acetate copolymers are selected, since they are widely used in many plastic bonded explosives. The technical objective of this investigation is to calculate for the surface free energy of RDX and EVA using theory of Fowkes, van Oss, Neumann approaches and Kaelble equation and to predict the interaction between filler and binder from their surface free energies.
