도심과 사회기반시설의 확장에 대한 수요로 인해 군사시설의 이전이나 시설의 지하화가 지속적으로 요구되고 있다. 그러나 탄약시설과 같은 시설을 횡단할 때에는 탄약이 우발적으로 폭발하지 않도록 고도의 안전성 평가가 선행되어야 한다. 이에 지중 구조물의 건설을 위한 발파작업이 지상의 탄약시설에 미치는 영향을 분석하기 위해 국방부와 한국철도시설공단간 협의에 의해 진행되는 신안선 복선 전철 설계구간 중 군사 보안구역을 통과하여 건설되는 터널구간에 대해 사례연구를 실시하였다. 폭발현상에 의한 진동의 속도를 수치해석 프로그램인 GTS-NX를 활용하여 예측하였고 문헌조사를 통해 모든 형태의 구조물에 대해서도 안전에 영향을 미치지 않는 0.2cm/sec의 지반진동속도를 안전성 평가기준으로 제시하였다. 본 연구에서 활용된 안전성 평가지표와 절차는 향후 탄약시설을 횡단하는 사회기반시설 계획 시 안전성 평가의 지표로 활용될 수 있을 것이다.

군용항공기 감항인증은 감항성을 가지고 요구된 성능과 기능을 발휘할 수 있음에 대한 정부의 인증이다. 북대서양조약기구(NATO)는 최대이륙중량 150kg 이상의 군용무인기에 대한 감항인증 요구도인 STANAG-4671을 2009년에 배포하였다. 최근 150kg 미만의 소형무인기에 대한 감항인증 요구도인 STANAG-4703을 내부적으로 배포하여 검토 중에 있다. 우리나라는 국제적으로 통용되는 감항인증 기준인 STANAG-4671을 기타감항인증 기준으로 준용하여 군용무인기에 적용하고 있다. 하지만 STANAG-4671은 중량에 관계없이 동일한 목표안전수준을 요구하여 낮은 중량의 중 소형무인기에 대해서는 목표안전수준이나 설계 요구도가 과도하게 적용될 수 있다. 따라서 본 연구에서는 군용무인기 분류와 감항인증 기준을 분석하고, 지상피해 평가기법을 적용하여 최대이륙중량별 목표안전수준을 제시하였다.

The special organization that our military service is conscripted by the duty of national defense purposes to the period of military service. So couple of soldiers are think as the corresponds to college, or some knowledge layer from the operating management discarding period, lifetime value. But, now a day changed of the military life, it is when the individual soldiers can have some self-development and the lifelong education in terms of a period, and can changeing the footsteps of the new life that the function as a 'bridge' to activate production of barracks life. So that it can be supported themselves need to strive for human resource development. This study is being discussed on the correlation of military human resources and qualified operating and sustainable and promising future eligibility for qualified by taking advantage of the Boston Consulting Group Matrix(Boston Consulting Group Matrix).

This paper presents the development of the automatic safety inspection technique for the ammunition fuzes using radiography images. The technique inspects 49-ammunition fuze by detecting the X-ray or neutron radiographic images to check whether the fuze is unintendedly armed or/and some major assembled parts are at right place. To execute the program, we loads the image(s) for under test. After reading images, the program conducts a series of pre-image processing, and then starts inspecting input images by using the detection algorithms which are designed distinctively for each fuze. After completing the detection process, the program displays the final result of the fuze status: "safety or danger." Through this program, we can cut off the fuzes which have any doubt about safety, and can only provide absolutely safe fuzes, compared with the current naked eye inspection method.

수소에너지 기술은 4차 산업 시대에서 주목받는 중요한 분야로 수소와 산소를 활용하여 전기 에너지를 생성하는 기술이다. 이 기술을 군사 차량에 적용할 경우, 온실가스 감소, 무소음, 저 진동 및 낮은 발열량의 효과로서 군사적으로 전략적 이점을 얻을 수 있어 다국에서 수소 군사 차량을 위한 연구 중이다. 우리나라 또한 미래 군사 차량에 수소를 적용하고 소형화 및 AI를 통한 스마트화 시키는 미래전을 대비한 전략인 Army Tiger4.0 계획을 수립하였다. 또한 국방부는 군용 수소충전소 설치에 따라 군 내 수소차 보급에도 탄력이 붙을 것으로 예상하여 환경부와의 협력으로 군용 수소충전소를 전국적으로 확충하기 위한 계획을 수립하였다. 하지만 수소는 화재와 폭발 위험물질로 안전한 충전소 구축과 효과적인 관리를 위한 체계적인 제도가 필요하다. 현재 군에서는 지정한 수소충전소 시설의 분류와 설치 조건을 군 시설 설계지침서를 통해 확인하였다. 그 결과, 충전소는 주유 시설로 분류되며 인접 건물과의 최소 안전거리를 2m 이상으로 이격시키는 것만 명시되어 있을 뿐 안전거리에 대한 그 외의 내용은 명시되지 않았다. 폭발의 규모가 큰 수소의 특성을 고려하여 과학적 기법을 통해 사고 피해 범위를 정량적으로 파악하고 피해 거리 밖으로 최소 안전거리를 제시하였다.

In the early 1960s, US Air Force lost missile launch bases during ICBM development by a defect in the missile design and operation plan. U.S. DoD realized the limitation of the existing accident prevention method. Therefore, the weapon development required system safety activity, and procurement projects of U.S. DoD applied MIL-STD-882(System Safety). Development projects of U.S. DoD more emphasized the importance of system safety after the space shuttle Challenger exploded in 1986. Currently, Airworthiness certification for military aircraft uses system safety to minimize accidents. The domestic defense aviation R&D projects also use the system safety for the airworthiness certification. However, non-aviation weapon R&D projects rarely applied system safety. This paper presents a system safety application method for domestic weapon R&D projects by studying the U.S. military standards/organizations and domestic defense aviation projects.

Of the Korean military's 3,959 ammunition depots, 1,007 - more than 25% - violate safety requirements for distance and equipment. There is a risk of explosion in old depots that are vulnerable to various interior and exterior accidents. This paper examines 10 scenarios, with varying values for ammunition amount and safety distance. The study calculated the overpressure that can be applied to risk-exposure objects, based on the safety distance; expected damage was predicted using constructed spatial information from 3D explosion simulations. The simulations confirmed that explosion overpressure increased the most when the safety distance violation rate increased from 80% to 90%. It also confirmed that secondary damage such as fire and explosion can cause casualties and property damage when the violation rate is 60% or higher. The results show that building collapse becomes a risk with a violation rate of 70% or higher. We conclude that taking ammunition depot safety distance violation into account when planning military facilities and their land utilization could better protect life and property.

In recent years, the Korean Army made use of fork-lifters or conveyors when loading and/or unloading military material in order to prevent accidents and to promote efficiency of military material handling activities. However, in troops smaller thin battalions, manual material handling activities are still committed for many reasons. In this thesis, a brand new loading/unloading device for efficient military material handling or manual workers was developed, and its validation study was conducted through objective assessment based on electromyography, subjective assessment based on Body-Map technique developed by Corlett and Bishop, and finally work performance comparison. The results of EMG analysis showed that muscular workload improved by 24% when using the device compared to manual work without the device, and complain of each body part was remarkably reduced. In addition, remarkable effectiveness enhancement was observed in the work performance. Consequently, it could be concluded that ergonomic devices like one developed in this research should be studied further in the ergonomic sense as well as in the economical sense.

Insensitive Munition(IM) reduces the explosive weakness of munitions, at the same time, maintains its performances in the moment of discharge, which improves safety of soldiers and minimizes unexpected accidents and casualties from being shot in case of transportation, storage and military operation. Development of IM has been focused as the global trend, which was required to satisfy the demand of army that is to minimize the loss of non-battle forces and to retain the competitiveness in export abroad. In this study, we categorize all the munitions used by ROK Army, then determine the priority of IM by deploying AHP(Analytic Hierarchy Process) method. In conclusion, we suggest the priority of IM which is suitable to the affairs of ROK Army.

In this paper, the results of computational analysis for the stability and F.S.(Factor of Safety) of Bailey Panel Bridge have been presented by FEM(Finite Element Method). The computational analysis was conducted by using LUSAS V14.0 that is a program applicated in the field of Civil Engineering. 6-free beam elements and 3-free truss elements were considered and F.S. against Yield Stress of main sections(considered self-weight and Live-Load) was investigated through the linear-elastic analysis method. The results showed that currently used sections of bailey bridge satisfied for the standard F.S. unit and could be operated in drill of troops and battle fields.
