Many government offices have been proceeding a development of Enterprise Architecture(EA) according to apply Government-wide Enterprise Architecture'. Each office and working-level officials have had a hard time because of no guides related to a EA development method such as the Framework, Standards, Principle, Reference Model, Etc. This paper propose a method for developing e-Government Enterprise Architecture considered a characteristic of public institutes through analyzing existing cases. The method for development e-Government EA includes the EA Performance Management Model to monitor objectively each office's long-term business promotion because the e-Government EA development is a job of long duration and cooperation with many institutes. This method also combines the EA Change Management Activities for the officials to improve general knowledge about EA's idea and EA's value, etc. We show the EA case study of the Ministry of Government Administration and Home Affairs to demonstrate feasibility of our approach. As a result, public offices will carry out their BPR(Business Process Re-engineering) and ISP(Information Strategy Planning) more efficiently based on this EA development method.

Recently, EA has been introduced in the Korean government as a tool for improving both IT management and IT investment. However, EA has been superficially used at the conceptual level without any efforts for facilitating it. As a result, it seems that any substantial outcomes from using EA could be hardly realized. This study suggests EA Service Model as a framework for facilitating the use of EA and then generating benefits. The purpose of EA Service Model is to provide a framework with which information and data can be linked, interconnected and shared in the whole process of IT management. It is expected that EA Service Model will possibly make a contribution to improving IT management. Empirical Analysis shows that key factors of EA Service Model make significant effects on improving the IT management, proving practical value and the validity of the model.

기존에 운영되고 있는 공공시설관리 시스템들을 효율적으로 관리하기 위해서는 유지관리 모형이 표준화되어 범정부EA 지원시스템에 목표아키텍처로 등록되고 더 나아가서는 범정부 표준시스템으로 만들어 필요한 기관에 보급할 필요가 있다. 이 연구에서는 도로, 터널, 철도 등 인프라 시설관리 정보시스템을 구축하는데 필수적인 성과참조모델을 범정부EA 관점에서 제시하였다. 제시한 참조모델을 기준으로한 자산관리모형 아키텍처 모습이 GEAP에 등록 관리 된다면 이것을 바탕으로 타 기관에서 향후 정보시스템을 구축할 때 사전에 파악하고 활용하도록 제안 할 수 있을 것이다.

ITA법 제정 이후 많은 공공기관들이 ITA/EA 도입 및 구축을 추진하고 있으나, 명시적인 성과를 보여주는 경우는 많지 않은 것으로 조사되고 있다. 특히, 공공기관 EA 성숙도 수준 평가 결과 EA 도입에 비하여 관리 및 활용 영역의 수준이 낮게 나타나고 있다. 본고는 EA의 활용성을 저해하는 제 원인 중 EA 관리체계의 부실에 주목하였다. EA 도입과 함께 EA관리 체계가 수립됨에도 불구하고 EA 관리 및 활용 수준이 낮은 이유는 첫 번째로, EA관리 조직 설계 시에 EA 산출물의 작성 주체 및 협업 방안이 구체화되지 않은 상태로 관리 조직 및 역할이 수립되는 경향을 지적할 수 있다. 두번째로 EA 관리체계 설계 시에 각 EA 산출물의 특성이 고려되지 않은 획일적 관리 프로세스의 설계로 인하여 관리체계가 오작동하는 문제를 지적할 수 있다. 본 연구에서는 이러한 문제의식을 근간으로 개별 산출물에 대하여 요구되는 정확성과 정합성 수준에 따라 범정부 EA 산출물들을 구성도/정의서(Diagram/Description)형, 모델(Model)형, 정보자동생성(Auto Description)형, 설계서(Description)형, 서지정보(Metadata)형으로 유형화하고, 각각의 산출물 유형에 따른 조직의 역할과 협업 방안, 관리 프로세스를 제시하였다. 본 연구를 통해 향후 EA 관리체계 수립 및 조정 시에 산출물 유형별로 작성 주체 및 관리 조직간 요구되는 역할과 관리절차를 명확히 함으로써 효율적인 EA 산출물 관리가 이루어지도록 하고, 이를 통해 궁극적으로 EA 활용도 증진 및 EA의 근원적 목적 달성이 가능할 것으로 기대한다.

The necessity of research for EA service and performance is surfacing while nation-level and individual agency level performances utilizing Government-wide EA information. In this study, performance model for EA service has been developed categorizing characteristic elements of EA as service. And weight differences between quality items that constitute performance model have been calculated using AHP analysis method. To achieve the stated, SERVQUAL applied performance model for EA service has been developed working through logical reasoning and a broad range of theoretical studies concerning EA service. Moreover, relative weight differences between quality items that constitute the model have been calculated. The results of weight analysis find that importance differences between quality items in order of significance are as follows: EA administrator > EA information > EA education > EA policy > EA operating system. This study, as the nation's first research to graft the public-sector EA service onto SERVQUAL Model that is capturing remarkable attention, has considerable practical and theoretical implications.

공공시설 자산관리는 기존의 대응적 유지보수 개념의 시설물유지관리체계에서 예방적 유지보수 개념으로 전환한 시설물 유지보수의 새로운 개념이다. 기존에 운영되고 있는 공공시설관리 시스템들을 효율적으로 관리하기 위해서는 자산관리 모형이 표준화되어 범정부EA 지원시스템에 목표아키텍처로 등록되고 더 나아가서는 범정부 표준시스템으로 만들어 필요한 기관에 보급할 필요가 있다. 이 연구에서는 공공시설 자산관리 정보시스템을 구축하는데 필수적인 참조모델을 시스템의 상호운영성과 정보의 호환성을 확보하기 용이하도록 범정부EA 관점에서 제시하였다. 제시한 자산관리 참조모델이 GEAP에 등록 관리 된다면 이것을 바탕으로 타 기관에서 향후 정보시스템을 구축할 때 사전에 파악하고 활용하도록 제안 할 수 있을 것이다.

Many Countries are recently focued on building capability based military and operating for the defense budget efficiency and operational effectiveness. The EA not only defines enterprise scope but also identifies relation among them, manage change and complexity. Accordingly, this research aims to build architecture framework which can achieve alignment, integration and interoperability by developing it with output. Through this, architecture framework can be changed into force development and operation. And it can be used for construction of effective force and operation for NCO by applying mathematical model and method of force priority development based on developed capabilities-based architecture framework.

Korea has won 3 times in a row in the evaluation of e-government services in 2014. And the last year, the government-EA has been awarded the UN Public Service Award. Because of the development and execution of personalized integrated services based on the government-EA, Korea has won the two award from the UN. EA has been selected and proceeded as one of the 31 e-Government projects in early period, in 2005 the law which public sector must adopt the EA for efficient informatization had been enacted. Many public agencies in which actively utilized to derive such as internal and external performance through the EA. On the other hand, in the last 10 years, some public agencies have still been as recognized level of management in the EA. In this study, the main purpose is that to find out what is a major factor for successful use and result of EA, what is the EA success Model and how to examine it. To do that, this study will study the related prior research such as EA services, information systems success factors, performance measures, and develop the success model for EA and then examine the model. This study will contribute great implications in practical and theoretical in EA success model because this is the nation's first research that SERVQUAL model and the IS Success Model(DeLone & McLean 2003) has been combined and examined.

Recently, several researches are focused on the frequency sharing and the liberalization of frequency use for utilizing the limited frequency resources efficiently. In military, as Network Centric Warfare(NCW), which requires significant mutual operability of battle elements and real-time operation speed, has come to the fore front as an important aspect of modern warfare, the methods to manage limited frequency resources in wireless communications environment efficiently has been studied and utilized. In this paper, we propose a Spectrum COP(Common Operation Picture) design suitable for the battlefields of air force. To construct the Spectrum COP of Air Force, we analyze the requirements and design the frequency management system by using EA(Enterprise Architecture) Framework. The simulation results of the proposed design proved the effectiveness by using EADSIM(Extended Air Defense Simulation) of Air Force.
