This study was designed to help develop an optimized sizing system for the military winter jackets of Korean males. First, we conducted a survey on the supply rate of military winter jackets and the wearing of suitable size jackets in order to identify problems in the current sizing system. We next developed a new sizing system generation method to satisfy the coverage rate and appropriate size number: Hybrid of Grid with Optimization. The findings of this study were: 1. The survey indicated that a 90 (chest girth) size is necessary; in addition, a one-step large size jacket fit well as a right size jacket. 2. We developed three optimized sizing systems for Korean male military winter jackets using the Hybrid of Grid with an optimization method and suggested one of them as a final new sizing system. The new sizing system consisted of two primary dimension: chest girth and stature. It has a 14 size number and its extended coverage rate is larger than the current sizing system and it has a 90 (chest girth) size. It also selected an optimized size for the area of low population density. The new sizing system is therefore considered very effective for Korean male soldiers military winter jackets.

Strategic decision on the execution of national security improvement project is greatly important for the present and future national security. Though, the importance of strategic decision, decision making process has been executed under one-way thinking framework. This research provides a decision-making tool with make-or-buy approach for the national security improvement policy execution methods: foreign purchase and military R&D project, and, via simulation, confirms dynamic change of military capability index respect to change in ratio of foreign purchase and military R&D. A result shows that current ratio of foreign purchases and military R&D is insufficient for national security improvement policy goal. Applying the model from this research provides an appropriate ratio for short term and long term defense strategy and policy goal, and consequent result of increase in national security capability. Thus, this research model can be effectively utilized for national security improvement project.

최근 사이버 공격기술을 활용해 목표시스템을 직접 공격하는 기술적 사이버작전 대신 목표시스템을 관리하는 사람의 취약점을 이용해 목표시스템에 침입하는 사회공학 기법이 각광을 받고 있다. 이러한 추세에도 불구하고 사이버 작전과 사회공학 기법 사이의 연관관계에 대한 명확한 개념이 정립되어 있지 않아 많은 혼란이 있는 것이 현실이다. 따라서 본 논문에서는 사회공학 사이버작전에 대한 명확한 개념정립을 통해 향후 사회공학 사이버작전에 대한 심도있는 연구를 위한 토대를 마련하고자 한다.

공공 시설물별 특성을 반영하기 힘든 Incremental Budgeting 모델에 근거한 유지관리예산의 산정 및 배정은 유지관리 요구와 투자예산간의 관련성을 더욱 격리시켜, 시설물의 조기 노후화를 발생시키고 있다. Incremental Budgeting 모델의 문제점을 개선하기 위한 노력이 일부에서 진행되고 있으나, 기존 모델의 테두리에서 이루어져 근본적인 처방이라 보기 힘들다. 공공 시설물 유지관리예산모델의 해결방안은 새로운 시각에서 바라보아야 한다 이러한 관점에서 $50\%$ 이상이 80년대 이전에 축조되었으며, 최근 대형화$\cdot$현대화되는 추세인 국방시설을 대상으로 문헌연구와 전문가 면담조사를 통해 적합한 유지관리예산모델을 선정하고, 이에 따른 현행 업무프로세스를 개선하였다.

This study focuses on Yusam, a military raincoat that was worn during the Joseon Dynasty. The purpose of this study is to review the types and management system of Yusam. Documentary records, paintings and relics were used as research materials. Yusam was recorded as either Yusam(油衫) or Yu-ui(油衣) in writing. It usually looked like a skirt and was worn like a cape, but there were differences in length. Some of them took the form of a short coat with half-sleeves and side slits. Research analysis results of Silrok, Ilseongrok and the archives of the military camp in the later Joseon are as follows: First, Mokyusam and Jiyusam coexisted as military raincoats. Mokyusam was made with cotton and perilla oil, while Jiyusam was made with traditional Korean paper, a cotton edging and perilla oil. Second, the differences between general Yusam and military Yusam include the material of the clothing, the materials for waterproofing, the color, and the manufacturer. Third, each military camp supplied soldiers with hundreds to thousands of Yusam. Military officers and King's guards wore Mokyusam because Mokyusam was higher than Jiyusam. Fourth, soldiers Yusam together with Yujeongeon, Chorip, Galmo, or Hwihang as a hat. Fifth, the higher the rank, the higher the price of Yusam and the longer the term of usage. On the other hand, as the rank got higher, the cost of the supplementary oil rose, while the duration of usage got shorter.

본 연구는 군내 사고에 영향을 주는 관련요인 추출을 위한 연구로서, 장교 및 부사관 227명과 병 300명을 대상으로 설문을 실시하였으며, 그 결과 3개의 개인적 요인, 3개의 사회적 요인, 3개의 부대내적 요인 등 9개 요인을 추출하였다. 추출된 9개 요인을 독립변수로 하고, 4개의 군 사고유형을 종속변수로 하여 회귀분석한 결과, 여러 요인들이 군내 사고를 설명하는데 매우 유용하다는 것을 발견하였으며, 특히 부대내적 요인이 군내 사고를 설명하는데 있어 매우 중요하였다. 본 연구 결과는 군내 사고예방을 위한 조기경보 시스템에 유용하게 사용될 수 있을 것이다.

The purpose of this study was to examine the satisfaction level of military personnels dispatched to Iraq with foodservices in a bid to help establish an efficient overseas military foodservice system. A total of 300 soldiers who served in an army division dispatched to Iraq was surveyed for this study. Regarding connections between the type of management and satisfaction level with foodservices, the contracted cafeterias were more satisfactory in terms of service than the military selfoperated ones, which indicated that it’s urgently needed to improve the service of the military-run cafeterias. The present work force of the Ministry of Defence makes it hard to provide military personnels with specialized foodservices. The military foodservice should provide meals to soldiers with quality. More branded concepts should be improved in the view of cost and effect. Or it’s advisable to take advantage of private resources as part of efforts for civil-military collaboration.

In this paper, we propose an architecture design of military operation system utilizing cellular networks. The main contribution of this paper is to provide a cost-effective military operation solution for ground forces, which is based on IT(information technology). By employing the cellular phones of officers' and non-commissioned officers' as the tools of operational communication, the proposed system can be constructed in the minimum duration and be built on the four components: command and control system, gateway, security system, and terminal(cell phone). This system is most effective for the warfare of limited area, but the effectiveness does not decrease under the total war covering the whole land of Korea. For the environmental change of near future, expanded architecture is also provided to utilize the functionalities of smart phones.

In this paper, we verify the performance of LDPC coded OFDM/DS system by Monte-Carlo simulation of BER on Eb/No. The simulation results show that LDPC coded OFDM/DS has a strong anti-jamming characteristic over pulse-noise jammer and partial-band noise jammer. The performance of LDPC coded OFDM/DS system is evaluated on both faded waveforms and non-faded waveforms. For non-faded waveforms, high coding gain is attained due to LDPC, even when waveforms have short PN sequence and JSR is only 5dB. Especially, the increase in the repeated number of LDPC decoding enhances coding gain. However, faded waveforms cannot achieve sufficient average effect when PN sequence is short. High coding gain of faded waveforms can be achieved by extending length of PN sequence. In addition, we compare LDPC coded OFDM/DS system with Convolutional coded OFDM/DS system. The simulation results illustrate that when LDPC coded OFDM/DS system with short PN sequence has sufficient average effects, the system shows lower BER than Convolutional coded OFDM/DS system with long PN sequence.
