This paper proposes characteristics of management system for defense system development. This research shows how effectiveness of SBA (simulation-based acquisition) can be represented even necessity of SBA is recognized by researchers. To achieve this goal there are two key information, (1)the cost for modeling and simulation and (2) number of trial and error of a certain step in a phase. This paper presents user interface of gathering those two key information and a way of showing the effectiveness of SBA using those two information. In this work, all the data gathering for calculation of effectiveness should be considered as a saving logs. The contribution of this research is in presenting quantitative value representing effectiveness of SBA and proposing a system architecture for deriving the quantitative effectiveness.

This paper presents an SBA (simulation-based acquisition) effectiveness analysis environment using the RUP (Relational Unified Process) model. The RUP model has 4 phases which cover the whole development steps such as requirement analysis, design, development and test. By applying the RUP model, SW development can be represented with the iterations of developments for each phase. Such a characteristics of the model would make the model suitable for defense acquisition. In this paper, we show the relation between the RUP model and V process model, which is the foundation for defense acquisition. In order to show how the model could be applied to SBA effectiveness analysis, graphical user interfaces for the analysis are presented at the end of the paper.

The weapon system acquisition for national defense is too costly, risky and requires high quality result. Because of these characteristics of the weapon system acquisition, the modeling and simulation is a prerequisite process for enhancing the effectiveness and efficiency of weapon system acquisition. We call the process as SBA (Simulation Based Acquisition). However the modeling and simulation entails costs of model development, execution and analysis. Thus, the SBA's effectiveness analysis is needed. Especially, we developed 4 types of index which represent the effectiveness thoroughly and we applied them to various weapon systems' acquisition process. This work presents the necessity of SBA by showing the application of suggested effectiveness index in various defense weapon system acquisition cases.

M&S 기반의 가상환경 설계운영은 자원절약 및 위험성 감소 등 다양한 측면에서 효율성을 지니고 있다. 국방은 현실세계에서 실시하기 어려운 군사작전 시뮬레이션 운영을 위해 국방 M&S 개념을 도입하고, 이를 기반으로 무기체계의 소요도출부터 전력화 단계까지 프로세스 전반에 걸쳐 가상 환경에서의 설계 운영 및 검증을 수행하는 SBA 를 도입하였다. 그러나 모델링 및 시뮬레이션 과정에서 발생되는 고비용, 위험성 등의 문제점은 SBA 도입 효율성에 대한 논란의 요인이 된다. 따라서 SBA 도입 효과를 입증할 수 있는 지표 제시가 요구되며, 이 연구에서는 입증 지표로서 비용, 시간, 품질 및 위험도의 4 가지 요소를 분석한다. 또한 소프트웨어 개발비용 산정의 어려움 및 SBA의 고비용 가능성을 이유로 SBA 에 대한 개발비용 산정의 필요성을 제기한다. SBA 개발비용 산정을 위해 기존에 제시된 소프트웨어 개발비용 산정 모델 적용을 제안하고, COCOMO 모델, Putnam 모델, FP모델, 전문가의 감정 및 델파이 기법 등 소프트웨어 개발비용 산정모델을 기반으로 SBA 개발비용 산정에 적합한 모델을 분석한다.

The principle of Effective Based Operation applied to the Korean Theater resulted in measurable effects to win the minimum battle. Based on the finding, this study recommends the effect analysis methodology under the V-C interoperability system to acquire a weapon system. This method is followed as below; to confirm the effect data on the organized weapon system, to set MOE, MOP and effect considering the purpose of the analysis, to apply the appropriate operational concept and scenario on the weapon system, and then the available C Model is after action reviewed, adjusted, and given feedback. The V-C interoperability system enables to perform the real-time combat experiment under the virtual synthesized battlefield circumstances. The defensive battle organization and displacement of the future anti-tank guided weapon system was considered in the modeling process. Scenario was written, which encompasses company-level units and the battalion-level operation. Then the available AWAM was embodied and effect-analyzed, which formed the foundation of SBA.

This study was performed to investigate the effectiveness of Hangryunhaedocktang (HHT) on epidermal damages induced by allergic contact dermatitis (ACD). The sensitization were caused by one application of $25{\mu}l$ of 5% 2,4-dinitroch1orobenzene (DNCB) onto a back-lumbar skin of BALB/c mice. 2 weeks later, ACD was elicitated with $4{\mu}l$ of 2.5% DNCB and then mice were given HHT extract in doses of 3.3ml/kg/day, for 72 hours. The ACD induced epidermal damages in HHT treated ACD mice was more mitigated than non-treated ACD elicited mice. The features related with epidermal damage such as epidermal hyperplasia, infiltration of inflammatory cells, increase of nuclear shrinkages and vacuolation, and enlargement of intercellular space softened. And the distribution of soybean agglutinin (SBA) positive reaction in stratum spinosum (SS) and stratum basale (SB) were similarly maintained in a normal configuration. The numerical decrease of BrdU, TUNEL, and Fas positive cells observed were prominent in SB. Results suggest a benefit role for HHT in mitigating epidermal damages in mice with allergic contact dermatitis.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.
