호주군은 1899년 제2차 보어전쟁에 참전한 이후, 제1·2차 세계대전, 6·25전쟁, 베트남 전쟁 등에 참전하였다. 호주군은 전쟁의 장기화로 나타난 군인의 사회적 인지도 하락과 지속적인 병력 부족 현상을 극복하기 위해 여성인력의 지위와 역할을 지속 확장하였다. 제2차 보어전쟁 간 의료지원으로 시작한 여성인력의 역할은 제2차 세계대전 시기 통신, 정비, 운전, 비밀문서 관리, 레이더 감시 등 전투 지원 임무로 확대되었다. 베트남 전쟁 이후 각 군 참모총장은 여성의 군 참여 확대를 위한 위원회를 설치하고 여성이 아닌 군인으로 인정하는 정책을 시행했다. 전쟁과 평화유지 활동에서 여성인력의 활약은 2014년, 특수부대를 포함한 모든 전투 직위가 여성에게 개방되는 계기가 되었고, 각 군은 2030년까지 여성 비율을 증가하는 계획을 수립하였다. 우리나라 역시 최근 지속되는 저출산문제로 인구절벽과 병력 가용자원 부족 문제가 대두되고 있는바 본 연구를 통해 호주군의 여성인력 활용의 역사와 현재의 모습을 통해 우리 군이 나아가야 할 방향에 대한 시사점을 도출하고자 한다.

Most video services are transmitted in wireless networks. In a network environment, a packet of video is likely to be lost during transmission. For this reason, numerous error concealment (EC) algorithms have been proposed to combat channel errors. On the other hand, most existing algorithms cannot conceal the whole missing frame effectively. To resolve this problem, this paper proposes a new Adaptive Prediction Unit-based Motion Vector Extrapolation (APMVE) algorithm to restore the entire missing frame encoded by High Efficiency Video Coding (HEVC). In each missing HEVC frame, it uses the prediction unit (PU) information of the previous frame to adaptively decide the size of a basic unit for error concealment and to provide a more accurate estimation for the motion vector in that basic unit than can be achieved by any other conventional method. The simulation results showed that it is highly effective and significantly outperforms other existing frame recovery methods in terms of both objective and subjective quality.

Jointness is a core concept of ROK military reform plan. ROK military has pursued to transform its military organization and capability for enhancing jointness and joint operation after the 1990s. It has strengthened the organization of JCS(Joint Chief of Staffs), introduced joint education, and acquired modernized weapons and equipment proper for joint operation. The 1986 Glodwater-Nichols Act of the U.S. military and lessons of the recent war provided a good direction how ROK military should take measures to enhance jointenss. In fact, defense reform efforts for jointness has produced invaluable fruits for transforming industrial age military forces into information age one which possesses more strong combat capabilities and develops joint business for efficient defense management. Nevertheless, there are many issues ROK military should address for stepping up the jointness. This paper well analyzes practical problems and issues ROK military faces to develop jointenss and draws policy recommendations for the policy makers.

본 논문은 함정 전투체계의 아키텍처를 설계하고 세부 기능을 분석 및 구현하기 위한 방안 연구를 위해 작성되었다. 함정 전투체계와 같이 복잡도 높은 대규모 시스템에서 문서 산출물에 근거한 개발은 산출물 간 유기적인 연결이 어렵고 요구조건의 변화에 따른 영향 요소 식별 및 반영이 어렵다는 단점을 갖는다. 이에 대한 대안으로 제시된 모델 기반 개발 방법론을 함정 전투체계에 적용하기 위해 미 국방 분야 표준 아키텍처인 DoDAF와 이를 지원하는 UPDM, 시스템 엔지니어링과 소프트웨어 엔지니어링 분야의 모델링을 지원하는 SYSML/UML을 살펴보고 함정 전투체계에 적합한 모델 구성 및 각 개발 단계 별 모델링을 수행하는 절차에 대한 가이드라인을 제시한다.

The emergence of computer-based information society has fundamentally changed the paradigms of everyday human life and will continue its trend in the 21st century when resources of information technology become more and more important because they can be directly transformed into military use. Future warfare will include such high-tech weapon systems as precision-guided munitions and satellite. But, with the spread of internet and advances in information technology, cyber space appears to be resources can be deciding factor in winning future war. In this paper we proposed to identify core information technology in national defense, improve mobilizing method of information resources in time of crisis, come up with combat effective measures utilizing information technology by estimating future information technological developments.

Aerothermodynamic flowfields of aircraft engine nozzles are computationally investigated at various flight conditions for infrared signature analysis. A mission profile of subsonic unmanned combat aerial vehicle is considered for the case study and associated engine and nozzles are selected through a performance analysis. Computational results of nozzle and plume flowfields using a density-based CFD code are analyzed in terms of thrust, maximum temperature, length and optical thickness of plume. It is shown that maximum temperature, length, and optical thickness of nozzle plume increase for lower altitude and higher Mach number.

Adaptation of infections and hosts has resulted in several metabolic mechanisms adopted by intracellular pathogens to combat the defense responses and the lack of fuel during infection. Human tuberculosis caused by Mycobacterium tuberculosis (MTB) is the world's first cause of mortality tied to a single disease. This study aims to characterize and anticipate potential antigen characteristics for promising vaccine candidates for the hypothetical protein of MTB through computational strategies. The protein is associated with the catalyzation of dithiol oxidation and/or disulfide reduction because of the protein's anticipated disulfide oxidoreductase properties. This investigation analyzed the protein's physicochemical characteristics, protein-protein interactions, subcellular locations, anticipated active sites, secondary and tertiary structures, allergenicity, antigenicity, and toxicity properties. The protein has significant active amino acid residues with no allergenicity, elevated antigenicity, and no toxicity.

Staphylococcus aureus is a prominent multidrug-resistant pathogen known for its resistance to a variety of antibiotics. To combat this, a wide range of antibiotics, including quinolones, is utilized. While the efficacy of quinolones against S. aureus has been established, the rise in quinolone-resistant strains, particularly in methicillin-resistant S. aureus (MRSA), has necessitated a shift in their usage patterns. Genomic sequencing plays a crucial role as it offers insights into the genetic mechanisms of resistance. Thus, we report the complete genome sequence of an oxolinic acid-resistant strain of S. aureus isolated from sweet potato leaves, a crop commonly cultivated in Korea.

Advanced tanks in the future combat system are expected to have the trends of large caliber, high explosive shell and light weight for destructive power and improvement in mobility. Their guns are required to have longer barrels to meet increased muzzle exit velocities. However, as the length of the barrel is extended, the vibrations induced by the breech forces in fire and the terrain lead to increased muzzle pointing errors. Therefore, the fire-induced and terrain-induced vibrations must be attenuated. A method to reduce these vibrations without the significant increase of the gun mass is to use the forward thermal shroud as part of a tuned mass damper. In this study, the dynamically-tuned-shroud using this shroud and leaf springs is introduced and its effectiveness on the vibration attenuations of the barrel are verified. The parametric studies on the stiffness of these leaf springs are performed and the analytical results are verified using the experimental model of the dynamically-tuned-shroud.

군은 현재까지 물적인 흐름인 군수지원체제를 발전시켜 왔지만 군수지원 서비스에 대한 충분한 연구는 수행되지 않았다. 본 연구는 군수 기능(정비, 보급, 급양)에 따라 종사자의 직무만족을 분석하고, 나아가 군수부대의 직무만족과 사용(전투)부대의 서비스품질 인식의 관계를 분석하고자 하였다. 연구결과는 첫째 군수부대 직무만족에서는 기능에 따라 유의미한 차이가 나타났으며, 둘째 사용부대의 서비스품질 요인 중 유형성에서 기능에 따라 유의미한 차이가 나타났다. 마지막으로 사후분석을 통해 서비스품질에 관한 의미있는 결과가 확인되었다.
