군(軍)에서 방위력개선사업(이하 방위사업)은 매우 투명하고 효율적으로 이루어져야 함에도, 방위사업 관련 법 및 규정의 과도한 다양화로 많은 실무자들이 원활한 방위사업 추진에 어려움을 겪고 있다. 한편, 방위사업 관련 실무자들이 각종 문서에서 다루는 법령 문장은 문장 내에서 표현 하나만 잘못되더라도 심각한 문제를 유발하는 특징을 가지고 있으나, 이를 실시간으로 바로잡기 위한 문장 비교 시스템 구축에 대한 노력은 미미했다. 따라서 본 논문에서는 Siamese Network 기반의 자연어 처리(NLP) 분야 인공 신경망 모델을 이용하여 군(軍)의 방위사업 관련 문서에서 등장할 가능성이 높은 문장과 이와 관련된 법령 조항의 유사도를 비교하여 위법 위험 여부를 판단·분류하고, 그 결과를 사용자에게 인지시켜 주는 '군(軍) 보고서 등장 문장과 관련 법령 간 비교 시스템' 구축 방안을 제안하려고 한다. 직접 제작한 데이터 셋인 모(母)문장(실제 법령에 등장하는 문장)과 자(子)문장(모(母)문장에서 파생시킨 변형 문장) 3,442쌍을 사용하여 다양한 인공 신경망 모델(Bi-LSTM, Self-Attention, D_Bi-LSTM)을 학습시켰으며 1 : 1 문장 유사도 비교 실험을 통해 성능 평가를 수행한 결과, 상당히 높은 정확도로 자(子)문장의 모(母)문장 대비 위법 위험 여부를 분류할 수 있었다. 또한, 모델 학습에 사용한 자(子)문장 데이터는 법령 문장을 일정 규칙에 따라 변형한 형태이기 때문에 모(母)·자(子)문장 데이터만으로 학습시킨 모델이 실제 군(軍) 보고서에 등장하는 문장을 효과적으로 분류한다고 판단하기에는 제한된다는 단점을 보완하기 위해, 실제 군(軍) 보고서에 등장하는 형태에 보다 더 가깝고 모(母)문장과 연관된 새로운 문장 120문장을 추가로 작성하여 모델의 성능을 평가해본 결과, 모(母)·자(子)문장 데이터만으로 학습시킨 모델로도 일정 수준 이상의 성능을 확인 할 수 있었다. 결과적으로 본 연구를 통해 방위사업 관련 군(軍) 보고서에서 등장하는 여러 특정 문장들이 각각 어느 관련 법령의 어느 조항과 가장 유사한지 살펴보고, 해당 조항과의 유사도 비교를 통해 위법 위험 여부를 판단하는 '실시간 군(軍) 문서와 관련 법령 간 자동화 비교 시스템'의 구축 가능성을 확인할 수 있었다.

The term of defense procurement is used indifferently from defence acquisition. It consists of two sectors : domestic defense procurement and foreign defense procurement. For efficient and transparent defense procurement, Defence Acquisition Program Law in Korea suggests some principles including the purchase of domestically manufactured munitions in the first instance, and the Defense Acquisition Program Administration(DAPA)'s direct procurement of munitions, etc. By reviewing the characteristics, process, current situation and model contracts of defense procurement, it is found that domestic procurement contracts only propose the legal approach instead of arbitration and foreign procurement contracts suggest confusedly both the legal approach and arbitration for amicable disputes settlement. Therefore, it is quite recommended for arbitration organizations such as the Korean Commercial Arbitration Board(KCAB), the Korean Arbitrators Association(KAA), and the Korean Association of Arbitration Studies(KAAS) to foster a variety of strong awareness campaign, education and consulting programs, etc. for the popular use of arbitration clause. It will contribute to settle any disputes and controversies between the parties more speedy, economically and rationally, thereby reducing the costs, time and pains for solving them.

The purpose of this study is finding the key factors for navy to determine the necessity of naval ship PIP(Performance Improvement Program) against the altered battle field environment and politics. Recently, leading countries try to cope actively with the changing international circumstances and technology development trend in the commercial industry. In the case of domestic situation, based on the regulation, it is possible to modify the ship configurations by PIP, but there are not enough criteria and references to make a decision of necessity for the PIP program considering the naval ship acquisition planning by navy. It is necessary to acquire the obvious decision criteria for determination of PIP commencement, by the operational, political and security environment around the Korean peninsula. Considering these conditions, this study proposes the factors necessary for naval ship PIP for navy.

To build up the military strength based on information oriented armed forces, the Korean ministry of national defense (MND) promotes the defense CALS (Continuous Acquisition and Life cycle Support) initiative for the reductions of acquisition times, improvements of system qualities, and reductions of costs. These defense CALS activities are the major component of the underlying mid and long term defense digitization program and the ultimate goal of program is to bring a quick victory by providing real-time battlefield intelligence and the economical operations of the military. The concept of defense CALS is to automate the acquisition and disposition of defense systems throughout their life cycle. For implementing defense CALS, the technology for exchange and sharing CALS standard data that is created once and used many times should be considered. In order to develop an efficient CALS information exchange and sharing system, it is required to integrate distributed and heterogeneous data sources and provide systematic search tools for those data. In this study, we developed a content based search engine technology which is essential for the construction of integrated data environments. The developed technology provides the environment of sharing the CALS standard data such as SGML(Standard Generalized Markup Language) and STEP(Standard for The Exchange of Product model data). Utilizing this technology, users can find and access distributed and heterogeneous data sources without knowing its actual location.

Technology transition from defense technology to weapon system is an important process for defense acquisition program. Many countries such as USA, UK, Australia and Republic of Korea use technology readiness level (TRL) as a tool for technology transition by identifying critical technology elements (CTEs) and assessing the technology maturity. In this paper we review a transition process for the defense acquisition. Then we suggest a method to evaluate system's TRL using each component TRL and integration readiness level (IRL) between each technologies. We apply the method to an ACTD project. A result show that technology maturity is influenced by integration between technologies.
