  • 본 논문에서는 고속철도 표준사면에 대해 안전율 평가와 확률론적 방법에 의한 신뢰성 해석을 수행하였다. 원지반과 흙 쌓기재료의 지반정수에 따른 안전율 변화경향과 신뢰도 지수 및 파괴확률의 분포경향을 확인하였다. 철도표준 성토사면에 대한 사면안정 해석결과 점착력과 내부마찰각은 단위중량에 비하여 안정성에 상대적으로 큰 영향을 미치는 것으로 나타났다. 또한 국내 철도 표준성토단면에 대한 신뢰성 해석결과 미공병단 기준에 의거하여 대체적으로 "평균이하(Below average)"의 수준이며, 건기 시 성토높이 12.0m에서는 "나쁨(Poor)"으로 나타났다.

  • As North Korea's asymmetric threats are growing, there have been numerous discussions to find out effective counter-measures and many official plans and procurements efforts have been established. However, discussions on ROK Navy's roles in countering North Korea's asymmetric threats have been taken place very limitedly. Decision makers and military planners put enormous efforts in getting counter-measures, however, most of the options on the table are systems of Army and Air Force. This is true if one looks at components of Kill-Chain, KAMD, and KMPR. With worsening security environment of the Korean peninsula, it has been said by many commentators that ROK Navy needs to consider expanding its roles in countering against North Korea's asymmetric military threats. They asked ROK Navy to go beyond the mind-set that has confined Navy's roles in deterring North Korean naval threats. That is, ROK Navy should fight 'from the sea' as well as fight 'on the sea.' If ROK Navy begins to think about fight 'from the sea,' there would be many possibilities for the Navy to be a part of countering North Korea's asymmetric military threats. In order to pursue proactive roles in countering North Korea's asymmetric threat, ROK Navy needs to consider various options. Massive missile forces, nuclear-propelled submarines, naval special forces may be some of them. With those measures, ROK Navy would launch massive and decisive attacks from the sea without risking survivability of our forces. Considering North Korean Navy's weakness, it is very probable that sea would be safer place than ground or sky. Expanding ROK Navy's roles and being a proactive deterrent forces against North Korean asymmetric threats would provide very reliable counter-measures to South Korean military. Thus, military planners should think how to take the best advantage of expanded ROK Navy's roles and capabilities against North Korean asymmetric threats.

  • 학습민첩성은 새로운 환경과 경험 속에서 빨리 학습하여 생각과 행동을 유연하게 변화시키는 의지와 능력이고, 위기를 극복하고 조직의 문제를 해결하는 핵심역량이며, 언제든지 개발 가능하기 때문에, 군(軍)과 같은 조직 집단에서 활용할 수 있는 개념이다. 선행연구를 토대로 육군 간부의 직무특성과 개인학습민첩성이 학습만족도에 어떤 영향을 미치는지 연구를 진행하였다. 상·원사 216명을 대상으로 설문을 받아 SPSS 24.0을 이용하여 측정변인에 대한 신뢰도과 타당도를 검증하고, 가설에 대해 회귀분석으로 검증한 결과, 직무특성 하위항목 일부(업무과부하)가 부적인 영향을 미치며, 개인 학습민첩성 하위항목 일부(자기인식, 적극적 변화추구)는 학습만족도에 정적인 영향을 미치는 것으로 나타났다. 이는 군 사이버교육의 효과를 증진하기 위해서는 야전에서 업무가 과부하되지 않도록 조치하고, 군 조직에서 성과를 높이기 위해서는 자기인식 및 피드백을 바탕으로 적극적인 변화를 추구하는 개인 학습민첩성을 개발해야 함을 의미한다.

  • 본 연구는 군 병사의 군 생활스트레스와 군 생활적응 관계에서 대인관계능력의 조절효과를 알아보기 위한 것이다. 이를 위해 충남과 대전지역의 군 병사를 대상으로 설문조사를 하여 최종 453명을 분석하였다. 본 연구의 주요결과는 첫째, 군 병사의 계급과 병과에 따른 대인관계능력과 군 생활적응의 차이가 있음을 알 수 있었다. 둘째, 군 생활스트레스가 높으면 대인관계능력은 낮아지고 군 생활적응도 힘들어지며, 군 병사의 대인관계능력이 높을수록 군 생활적응을 잘 하는 것으로 나타났다. 셋째, 군 생활스트레스와 군 생활적응간의 관계에서 대인관계능력의 조절효과를 검증한 결과 대인관계능력의 하위요인 중 개방성에서 조절효과가 있음을 확인할 수 있었다. 본 연구는 군 병사의 군 생활스트레스를 조절하여 군생활적응력을 높이기 위해서는 대인관계능력 중 개방성의 능력을 향상시킬 수 있도록 돕는 것이 중요함을 시사한다.

  • The purpose of this paper is to examine the street fashion, which is influenced by the youth culture in 1960s. Youth culture is the youth subculture which appeared multiform in the 1960s. It tried to create a new culture by subverting the ruling class culture with their combative life style and peculiar appearance which are distinguished from mother culture. Youth cultures as youth subculture are symbolically expressed in their style which had strong characteristics of sub-fashion and anti-fashion, and which are different from mother fashion in shape. Therefore youth subculture fashion had an effect on street fashion in the 60s. The influence that the youth culture fashion had had on the street fashion is summarized as follows: Beats fashion was intelligency look on black dress, black polo-neck shirts, black trousers, black glasses and heavy black eyeliner. Mods fashion was neat style on Edwardian suit with narrow trousers, pointer-toeshoes and smooth croped hair. Folkis fashion was ethnic look, middle east asian look, peasant look, Indian style, south america look, gypsy style, natural materials, natural dying, tie-dye, beads and hand made ornaments. Rockers fashion was violence appearance categorized 'blue collar' on black leather jacket decorated with metal studs and hand-painted insignia, blue jeans and boots for motor bike. Swinging London & the Psychedelics fashion was blend mods look with pschedelic color and motive pattern. Hippie fashion was intermix pschedelic and natural or ethnic style. It was appear to be a meaningless, unpredictable assortment of diverse items and style. Faded and tattered jeans, army jackets, vintage hat, beads, embroidered headband, white sheets, diverse theatrical costumes, sandals or bare feet, granny dress, peasant blouse, blanket cape, tie-dye T-shirts and long hair. Greasers fashion was adorned black leather jacket with chains, fringing, badges, insignia and sleeves had been crudely ripped off. They came to be known wore jeans so soaked with oil. Skinheads fashion was aggressive working class identity with donkey jacket, jeans rolled up, collarless union shirts, heavy boots, braces and hair cropped short.

  • For military training and course-of-action analysis, OneSAF Int'l version being used in ROK Army has a limited capability to simulate NBC(nuclear, biological, and chemical) damages. For high-fidelity NBC combat simulation, it is required to visualize NBC contamination dispersion in consideration of weather conditions and terrain characteristics. However, OneSAF itself handling interaction among thousands of combat entities cannot carry out a simulation of NBC contamination dispersion because it brings about an excess burden. To resolve this problem, this research aims to design simulation federation for analysis on NBC operational effects. After examining design consideration to connect OneSAF and a NBC contamination dispersion model, we design a federation architecture that facilitates the interaction between OneSAF and a NBC contamination dispersion model. Afterwards, we implement a federation interface to share simulation data by publish-subscribe pattern and to translate them into the proprietary format for each model. We prove the possibility of federation between both models, as showing that dispersion of NBC contaminated cloud and changes in concentration are reflected in OneSAF-based engagement simulation.

  • Since the demand for new military vehicle to fulfill the necessary conditions such as multi-purpose, high-mobility, and survivability has raised continuously from the army, the prototype of a Korean light tactical vehicle was developed to meet these requirements using our own technology. In particular, the new tactical vehicle was equipped with a double wishbone independent suspension to improve ride and handling and maximize off-road driving performance. In this paper, a comprehensive virtual durability process to evaluate the service life of the prototype is presented. A reliability of the trimmed body model based on CATIA data was verified by comparison result between mode analysis and modal test. The dynamic model was constructed using ADAMS/Car, and then the weight distribution and lateral slope driving performance of it were compared with the results of static weight and lateral slope tests. The validity of the VTL(Virtual Test Lab) was checked with test results from the 3-inch spaced impact road. The durability performances of trimmed body and suspension components were evaluated through MSM(Modal Superposition Method) fatigue analysis. It is shown that the virtual durability process could be a helpful tool to find out the weak areas and improve their structures in developing new military vehicle.

  • 제4차 산업혁명과 관련된 기술을 군 전력발전 업무에 적용하는 것은 더는 미룰 수는 없는 시대이다. 제4차 산업혁명의 기술이 최종적으로 전력분야에 적용될 대표사례가 무인체계이다. 아직까지 많은 무인체계가 육군에 전력화되지 않은 상태이며, 무인체계에 대한 친숙성을 높이는 것은 미래에 전력발전에 긍정적인 영향을 미칠 것이다. 이를 검증하기 위해서 구조방정식모델을 이용하여 정량적으로 분석하였다. 연구결과는 무인체계에 대한 친숙성이 높아지면 전력의 각 분야에 대한 활용 가능성이 높아지고, 결국에는 지상전력이 전반적으로 발전할 것이라는 기대감이 상승함을 보여준다. 이러한 연구결과는 군 양성 및 보수교육에 있어서 무인체계 친숙성을 높이는 교육이 강화되어야 한다는 점을 함의하고 있다.

  • 개산견적 모델은 예측의 정밀성뿐만 아니라 설계대안 변화에 대한 유연성, 사용자 중심의 효율성을 고려해야 한다. 본 연구에서는 이를 구현하기 위해 건축물을 구성하는 여러 포함시설을 건축양상에 맞게 주요 용도별로 분류하여 공사비 영향변수로 설정한 다음, 통계적 분석을 통해 용도별 시설단가 관계함수를 도출하여 공사비를 예측하는 용도별 분류에 의한 공사비 산정개념을 제안하였다. 그리고 대표적 군사시설인 육군 병영생활관을 대상으로 용도별 공사비 산정 개념을 모델화하고 신규사례를 대상으로 모델의 신뢰성을 검증하였다. 용도별 공사비는 견적의 정밀성을 향상시켰을 뿐만 아니라, 발주자 니즈(Needs)를 반영한 용도별 조합과 그 규모에 따른 맞춤형 공간을 계획할 수 있고 다양한 설계 대안에 대한 비용비교가 가능하다.
