본 연구는 복합시스템 환경에서의 능력기반 획득프로세스에 대해 기술하며, 인식 패러다임을 기반으로 쓰여진 정성적인 논문이다. 미래 전장은 단일전구 내에서 다양한 센서와 슈터가 각각의 그리드를 형성하고, 네트워크기반 전장관리체계에 의해 임무와 기능을 수행하는 복합시스템 개념으로 변화되고 있다. 복합시스템은 특정 능력을 충족시키기 위해 개별 시스템들을 보다 큰 시스템으로 통합한 시스템의 묶음 또는 배열이다. 따라서, 획득프로세스도 기존의 단일시스템 요구사항 중심에서 복합시스템 환경하의 능력기반 획득으로 변화되고 있다. 이러한 관점에서 본 논문은 능력기반 획득프로세스의 핵심 요소인 JCIDS, DAS 그리고 CEP에 대해 기능측면에서 분석하였다. 그리고, 이러한 종합적 분석결과로 부터 한국적 획득환경에 적합한 능력기반 획득적용방안을 제시하였다.

본 연구는 초등학교 2학년 1학기 '여러 가지 도형' 단원을 학습한 학생들이 갖고 있는 삼각형에 관한 개념 이미지를 확인하고자 한 것이다. 그 결과 학생들은 삼각형과 세모에 대하여 서로 다른 개념 이미지를 갖고 있음을 알 수 있었다. 삼각형의 정의를 기계적으로 암송할 수 있지만, 변과 꼭짓점에 대한 심상이 적절하게 형성되어 있지 않음으로 인해 삼각형을 판별하지 못하는 경우도 있었다. 무엇보다 삼각형이라는 용어는 각의 관점의 용어이지만, 2학년 교과서에서는 각의 개념을 도입하지 않은 채 변의 관점에서 도입함으로 인해 학생들은 각을 변이나 면으로 혼동하는 경우도 있었다. 이러한 결과를 바탕으로 초등학교 수학과 교육과정과 교과서의 개선 방안을 제안하였다.

Modern weapon systems are composed of complex systems(System of Systems) and require a complex and advanced operational concept that performs missions through interoperability with various weapon systems. In order to derive the operational concept of the weapon system that the military wants to acquire (i.e., single mission, component operation, Joint and Alliance operations), it is necessary to identify the system related to the weapon system, environmental factors and restrictions of the weapon system to be developed. Through the derivation of the operational concept, the weapon system acquisition agency can reasonably and accurately extract various and complex requirements. In this paper, we propose a complementary method of using MND-AF to OCD and ORD required in weapon system acquisition process. MND-AF can increase the understanding and consensus of business stakeholders (users, acquirers, developers, etc.) by showing the results of weapon system analysis from various perspectives. We compare the items in the standard form of OCD and ORD with the MND-AF outputs.

Although the concept of viewing knowledge as a critical resource has been widely accepted in prior studies, it is not fully understood how to acquire available knowledge in order to improve organizational effectiveness. However, it si sure that organizational knowledge management should pursuit the achievement of the business goal by delivering relevant and useful information to the right person at the right time. Group Support System (GSS) can play an important role to transfer scatter information into meaningful business knowledge for supporting strategic corporate decision-making. This study proposes a fuzzy GSS framework for acquiring workgroup knowledge from individual memory and aggregating workgroup knowledge to organizational knowledge. This study also proposes an architecture to support the fuzzy GSS framework. The architecture consists of user agents, information management agents, and a fuzzy model manager. To illustrate how the fuzzy GSS framework can be used to support the whole process of organization knowledge acquisition, an Internet-based GSS was developed and applied in a marketing decision process. It showed that the framework was effective for acquiring organizational knowledge.

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.

AutoCor is a method for the automatic acquisition and classification of corpora of documents in closely-related languages. It is an extension and enhancement of CorpusBuilder, a system that automatically builds specific minority language corpora from a closed corpus, since some Tagalog documents retrieved by CorpusBuilder are actually documents in other closely-related Philippine languages. AutoCor used the query generation method odds ratio, and introduced the concept of common word pruning to differentiate between documents of closely-related Philippine languages and Tagalog. The performance of the system using with and without pruning are compared, and common word pruning was found to improve the precision of the system.

The purpose of this study was to investigate methodological and theoretical problems in measuring the acquisition of national identity of in-country and over-seas Korean adolescents. The subjects consisted of 574 incountry and overseas (Chinese, Russia and Japan) Korean adolescents (total 509), 15 to 25 years of age. Data were collected with the use of a questionaire, the Scale of National Identity. The results were that (1) the concept of national identity was organized on two dimensions (cognitive vs. sociocultural). The former consisted of 6 cognitive characteristics (uniqueness, sameness, continuity, acceptability, respectability and royalty). The sociocultural dimension consisted of the cognition of 7 sociocultural characteristics (history, norm, fraternity, symbol, consanguinity, Korean language and nationality). Except for consanguinity, there was a close relationship within each and between the 6 cognitive characteristics. Also there was a close relationship within each and between the 7 sociocultural characteristics of national identity. (2) Some demographic variables, such as age of respondents, place of birth and level of understanding of Korean language contributed to acquisition of national identity. (3) Among several demographic variables, nationality was the most explainable.

The management systems of defense projects need to be well-maintained because of huge cost and long-terms of acquisition & operation in conducting defense acquisition. In this paper, we use a structural equation model(SEM) to develop an project management index(PMI) for effective defense project. The concept of a customer satisfaction index is used to assess the PMI for strategic improvement plans for various characteristics of project management. It is expected that our model can be used to evaluate and improve the project management capability of defense acquisition.

The KOMPSAT-2 DCSU(the data compression & storage unit) performs the acquisition of image data from cameras, the compression with requested compression rate, the storage with specified file ID on the mission command and the distribution to the assigned DLS(Data Link System) channels per the mission and operation requirements. The worldwide observation using the MSC is able to be achieved by this DCSU's behavior. This paper presents the features of KOMPSAT-2 DCSU and provides proper ground operation concept after launch.

Simulation-based acquisition(SBA)는 획득의 제단계에 모델링 및 시뮬레이션(M&S)를 적용함으로써 획득기간을 단축하고 무기체계 총 소유비용을 낮추며 소요군이 요구하는 성능목표를 가진 무기체계를 획득하고자 하는 새로운 획득 패러다임이다. 우리 군이 SBA의 정착을 위해 다각도의 노력을 기울이고 있음에도 불구하고 SBA의 성공적인 실행을 보장해 주는 청사진 역할을 하는 SBA 아키텍처 프레임워크에 대한 연구는 미진한 상황이다. 본 연구에서는 MND-AF를 기반으로 SBA 아키텍처 프레임워크 개념모델을 제안하였으며, 우리 군의 획득 프로세스를 근간으로 운영 뷰에 대한 모델링을 수행하였다. 또한 운영 뷰에 포함된 각종 운영활동들이 임무 완수를 위해 활용하게 될 도구와 기술을 식별했으며, 데이터들간의 상호운용성을 보장해주는 표준화된 데이터 모델을 제안해 시스템 뷰에 포함시켰다. 특히 시스템 뷰에는 통합사업 관리팀과 운영활동의 주체들이 분산되어 있는 M&S 도구들을 활용할 수 있는 SBA AF 포털이 포함되어 있다. 또한 SBA 아키텍처 프레임워크 개념모델에는 기술 뷰와 아키텍처 구축을 위한 최상위 지침서로서의 역할을 하는 올 뷰가 포함되어 있다.
