미상원 군사위원회는 87년 3월 25일 국방성의 베커원자력 담당차관보가 3월 23일 동위원회 전략.핵시스템 소위원회에서 증언한 의사록을 발표했다. 그것에 의하면 미국이 현재 개발.생산을 추진하고 있는 화학무기는 3종류가 있는데 FY 1991년까지 이를 모두 생산쳬제에 들어갈 계획을 분명히 하고 있다. 신형화학무기로는 155mm 포탄, Big Eye 폭탄, 다연장로케트탄의 세가지로 155mm 포탄은 현재 생산중이고, Nig Eye 는 실험중이며, 로케트탄은 개발중이라 한다. 화학무기근대화계획중 가장 중점이 두어진 것은 Big Eye 폭탄으로 소련군의 NATO 군에 대한 화학무리공격에 가장 효과적인 억지력이 될 것으로 기대하고 있다고 한다.

Penetration depth of inorganic waterproofing agent is difficult to assess quantitatively because inorganic waterproofing agent for concrete is not an internal waterproof membrane. However, evaluation of penetration depth of inorganic waterproofing agent is one of the most important evaluation index to secure efficiency in a consistent penetration. Therefore, this paper was proposed penetration depth measurement method of inorganic waterproofing agent for concrete and the penetration depth of the conventional inorganic waterproofing agent have been evaluated through the proposed penetration depth measurement method. As a result of test, the measured penetration depth throught the proposed penetration depth measurement method of inorganic waterproofing agent showed that more than 90% reliability.

The DMSMS(Diminishing Manufacturing Sources and Material Shortage) can occur in every weapon systems and especially, this phenomenon frequently occurs in electronic parts. But we have no DMSMS-related directives, guidelines, regulations and activities, so we have some difficulties in operating weapon systems. In this paper, we review the reality of DMSMS in our weapon systems and then suggest effective alternatives to reduce the risk of DMSMS for weapon systems.

In this study, permeable repair materials mainly composed of silicate - based inorganic materials(SIM), which are easily available domestically, were prepared as a basic study for the development of permeable repair materials using SIM. SIM were compared and examined for their performance as repair materials by selecting a product group which has many cases of use in foreign countries. The SIM used were mainly composed of sodium, potassium and lithium silicate. Performance evaluation of SIM was performed by absorption and penetration, compression and adhesion, rapid chloride ion penetration, rapid freezing and thawing, and chemical resistance test. According to the test results, SIM showed effective performance in all areas, mainly because SIM permeates into the interior of the capillary and has a dense internal microstructure. Therefore, it can be used variously to improve the durability of concrete based on the results of this experiment.

In this study, we prepared a core material based on the inorganic materials in liquid form for applying an inorganic-based core material to a core material for the self-healing capsules as a part of the basic study to manufacture of self-healing capsule that can heal cracks of cementitious composite. Manufactured core material based on the inorganic materials were applied directly to the cement composite before its encapsulation, were evaluated the effect on performance of cementitious composite as wall as repair performance of the cracks in the cracks. The test results showed that core material based on the inorganic materials was effective to improve the compressive and adhesion strength, had an absorption, permeation water, penetration of chloride iones and freeze-thaw resistance performance. Through the results of this paper, we want to utilize the results as a basis data of the performance of the cement composite that can be obtained when applied to inorganic core materials based on self-healing capsules and future advances localized self-healing capsule technology.

There are many demands for interoperability between weapon systems as the operational needs for joint and coalition based on network in modern and future warfare have been increasingly needed. In DoD, LISI has been applied throughout information system life cycle from the planning phase to the development phase to assess the level of interoperability. We also developed SITES which is a tool to assess the level of interoperability in information systems. But we should extend the assessment model from the previous information systems to the weapon systems to assess the level of interoperability including weapon systems as well as information systems. In this paper, we proposed the assessment model of interoperability, implemented the E-SITE based on the proposed model, applied 12 weapon systems and analyzed the experimental result.

As NCW has appeared, the importance of interoperability in modern warfare has been also increased. Korean Defense has constructed and used the Systems Interoperability Test & Evaluation System based on LISI, in order to increase interoperability between Defense Information Systems. However, its evaluating targets are limited to only the information systems, so that it is difficult to apply it to weapon systems. This paper proposes an integrated interoperability assessment framework for korean embedded software of weapon systems based on reviewing the limitations of SITES and the other interoperability assessment models.
