This paper proposes an effective method on the DFILS(Design for Integrated Logistics Support) in ammunition development applying QFD(Quality Function Deployment) method. The goal of this research is to define the Design for ILS approach at the start of the ammunition development and to yield a set of reusable requirements. Based on 000mm High-Explosive(Warship ammunition) development work, a QFD software tool, CUPID, was used to analyze and define the field force's requirements. Additionally, a set of reusable requirements are identified and defined for use during the Design for ILS development phase in the next-generation ammunition development process. These set of requirements that consider both the priority and importance of the VOC(Voice of Customer) will contribute to the early phase of the ammunition development to implement the Design for ILS specialty engineering effort.

21세기에는 정보기술의 혁명적 발전과 함께 전쟁양상이 파격적으로 변화되어 가고 있다. 이에 따라, 분산 다중 에이전트 시스템을 위한 기술 발전이 중요시 되고 있는 상황이다. 분산 다중 에이전트 시스템을 위한 기술이 발전함에 따라 국방 분야에 연구가 활발하게 진행되어지고 있다. 그러나 지금까지 분산 다중 에이전트에 대한 연구들이 기능적인 면에서만 집중되어 왔다. 본 논문에서는 ACL(Agent Communication Language) 메시지에서 파라미터를 Emergency, Normal, System로 추가함으로써 에이전트의 실시간성을 보장하는 'QoS(Quality of Service)를 보장한 분산 다중 에이전트 플랫폼' 제안하였다. 긴급한 메시지 전송 시 QoS Manager(QOMS)를 이용하여 스케줄링 하여 에이전트 플랫폼 시스템 성능 향상을 하는 방법을 제안한다.

As the core technology of the 4th Industrial Revolution is applied to drone, the potential for growth in the field of unmanned aerial vehicles is very large, and the utilization of civilian & military fields in the domestic & foreign is increasing rapidly. Because application areas of drone in the civilian field is various, it is excellent in terms of cost effectiveness and high value in utilization when it is used for military operation support mission. Especially, in the case of the Air Force, it is expected that military usage effectiveness will be high if drone replaces various air operations support missions such as aircraft inspection, supply of military supplies, base security. We find out the missions that can utilize drones for military operations support and propose the recommendation and data management plan accordingly. We recommend the most suitable drones and equipment that perform similar missions in the private sector and propose the data modeling of relational database.

'Anyu', a perilla (Perilla frutescens (L.) Britton) cultivar for edible seed was developed by the Department of Functional Crop Science, National Institute of Crop Science, RDA in 2008. It was originated from the cross between a pedigree of YCPL1824 as a female and SF9225-3-1 as a male parent in 1998. 'Anyu' can be characterized by purple flower color and brown grain color. 'Anyu' showed semi-dwarft type with 120 cm height, and has lodging tolerance. Maturing date of 'Anyu' was September 24, which is 15 days faster than that of 'Saeyeopsil'. The early maturity of this new cultivar showed a great advantage to various planting system with other crops. This new cultivar has high oil content (45%) and high linolenic acid in the fatty acid composition. The yield potential of 'Anyu' was about 0.9 ton/1ha in the regional yield trial.

Health functional foods refer to food which manufactured in the form of a tablet, capsule, granule or pill, using materials and ingredients with useful function for a human body in Korea. It needs to be confirmed as safe. Microbiological analyses on 37 samples of botanical raw materials used in the health functional food were performed. Microbiological analyses and probability of irradiation using PSL on 4 samples of aloe powder products were studied. In health functional food ingredients APC was $10^{3}-10^{6}\;CFU/g$ and coliform counts were $10^{2}-10^{5}\;CFU/g$. Among 37 samples B. cereus were found in 12 samples. Four samples of aloe powder products were tested for possible irradiation using preliminary PSL, Two samples of aloe powder products showed positive on preliminary PSL test for irradiation.

발포금속은 1948년에 Sosnik에 의해 알루미늄에 수은을 증발시키는 방법으로 발포 알루미늄을 제조한 이래, 1951년 Elliot에 의해 진보된 방식인 발포 매개체를 용탕에혼입하는 방법으로 발포금속을 제조하기 시작하였다. 현재 이들 선진국가의 생산방법 및 현황은 균질 기공의 조절, 연속주조 방식과 원가절감, 그리고 제조기술의 진보를 통하여 다양한 분야에 적용되고 있다. 그러나 실용화를 위해서는 요구특성을 만족하고 동시에 가격 경쟁력을 가진 제조기술의 보유 및 개발과 독특한 특성을활용한 새로운 적용 분야의 개척이 필요하다고 생각되며, 이를 위해 Harvard, MIT, Aachen, HMI 등 구미 유수 대학과 NASA, 미국방성등의 연구기관, ERG, 신강(新鋼) wire등 산업체를 중심으로제조 및 특성평가에 관한 기초연구와 활용방안이 활발히 모색중에 있다. 그리고 일부 자동차 생산 업체를중심으로 발포금속을 적용한 초경량, 에너지 절감형의 자동차 부품 소재,항공기 방열판 등에 대한 연구가 활발하게 진행되고 있다. 특히 금속 기체의 GASAR 공법은 Lotus 공법으로 Osaka 대학에서 개발되어 열교환기, 항공기, 방열기 등으로 응용이 확대되고 있다 국내에서 완제품생산은 실내장식용 복합패널로서 한소 프라임이 운영상의 문제로 생산을 중단하였으며, 유닉슨(주), 금강(주)에서 Batch식, 금성산업에서 Pot식이 일부 생산 및 연구가 진행되었으나 현재는 본연구실의 협조로 (주) 폼텍에서 발포패널을 주로 생산하고 있고 (주)드림메탈과 (주)아크로폼텍에서일부 생산되고, (주)동일알루미늄에서는 폐 scrap을 이용한 발포 Al 제조가 연구단계에 있다. 생기원에서는 분말 가열 흡음패널이 개발되었으나 강도와 내열성이 낮아 이들 특성을 향상시크는 연구가 진행중이다. 이들 제품은 성능상으로는 동양강판의 흡음패널과 KIMM의 필터용은연구개발이 낮은 수준이며, 본 연구팀과 공동 개발한 (주)폼텍의 복합패널은 10여 가지의 실용특허로 건축마감재로서 오히려 선진국수준을능가한 상태이다, 한편, 발포금속 기능성 개발은, 이들이 가지고 있는 우수한 특성 때문에 군수용으로부터 민수 산업용까지 전분야에 적용이 가능한 소재이므로 수요처를확장하고 있으므로 제품의 균질성, 안정성과 기능성 개발 향상을 위해 지속적이고 체계적인 연구가 필요하다고 생각된다.

The military purpose vehicles are developed by using the platform of civil vehicles according to the commercial vehicle expansion plan and military supplied product commercialization policy. But the information related to the military purpose vehicle which adopts the same platform with the civil vehicle is forced to be exposed because its information is revealed by containing into the maintenance manual and electric circuit diagram. Especially, the information disclosure should be blocked by reviewing the application of technology protection because the military vehicle becomes combating purposed mixed equipment when the missile and radar are mounted. The mixed equipment means the one configured with more than 2 types of equipment, and it is categorized into the main and sub equipment. This study was performed to derive the problems in Korean system for vehicle part test evaluation on the mixed equipment and the defense industry technology protection system, and to derive the methods for improving through interviews with the specialists. The conflicts between the civil laws and army regulation were reduced by adding a clause that the engine reflected with the newest emission gas standard should be mounted based on the time of force integration, and the commercialized military supplies were designated as element technology of defense industry technology in consideration of its roles and functions.

The main cause of DMSMS is the rapid replacement cycle and short life cycle of parts, according to the development of science, compared to the long life cycle of weapons systems. In particular, the problem of the supply and demand of such parts becomes even more acute during the operation maintenance phase after the mass production and power generation stage. To eliminate DMSMS problems that arise continuously from development to the operation of weapon systems and select the most cost-effective countermeasures to obsolescence, this paper suggests a standard to determine the appropriate time for quantitative performance improvement by conducting total life cycle cost analysis. For such purpose, this study examined the domestic and overseas cost analysis methods and applied it to single domestic weapon system to verify the research. This study responds to the issue of discontinuing components and helps reduce the total life cycle cost of military products.
