정부의 행정 서비스를 보다 효과적이고 효율적으로 제공하는 것은 정부혁신의 핵심키워드이다. 이를 위한 수단으로 정부 공공기관들은 전사적 아키텍처(Enterprise Architecture)를 적극적으로 도입, 활용해야 한다. 전사적 아키텍처란 아직까지도 진화중인 개념으로 해당 기관 정보화 업무의 전 영역을 업무 프로세스(Business Processes), 정보 흐름 및 관계(Information Flow and Relationships), 애플리케이션(Applications),데이터 명세 및 관계(Date Descriptions and Relationships), 그리고 기술 하부구조(Technology Infrastructure)로 구분 짓고 각각을 구조화된 산출물로 정리함으로써 공공정보화의 청사진을 제시한다. 이렇게 구축된 아키텍처 결과물은 기관 내 뿐 아니라 타 기관 EA와의 연계를 통해 상호 운용되어야 하며, 이 과정에서 어휘의미중의성(Word Sense Ambiguation)등 상호운용성 문제가 핵심 이슈로 대두되리라 예상된다. 공공분야로 한정짓더라도 200여 정부부처 EA간의 상호운용성 문제는 정부조직 간 경계를 넘어 통합된 EA정보를 취합, 활용하는 데 있어 가장 큰 장애요인이 되리라 예상된다. 본 논문에서는 온톨로지를 사용하여 각기 서로 다른 EA간 상호운용성 문제를 해결하는 방안에 대해 논의하고자 한다.

The managing strategies of each enterprise has been fundamentally changed due to the emergence of digital economics by using the internet. Therefore it is indispensable for each enterprise to be changed their business strategies. With a view to meeting the change of new economic paradigm, they are efforting to build a infrastructure for information and communication, induce foreign capital, reconsider their conditions of location, draw the law concerned and reinforce education for experts etc. In consideration of these change, the KwangYang port have to introduce e-Business for the purpose of increasing the level of their competition. We - our government, the companies - concerned with port management should recognize and use efficiently our core competence and potentiality of our port management. To achieve it, firstly port industries are to handle not only international logistic system but also communication, finance and sightseeing. Secondly, the developed off-line system have to be harmonizing with the on-line. Therefore, this paper are focused to suggest the theoretic background by analyzing the strategic points of e-port which are divided in 6C - Contents, Community, Connection, Commerce, Communication and Customization.

An electronic document based on PDF has been widely used in customer communication between an enterprise and a customer to deliver personalized content. However, electronic documents based on PDF in the form of paper layouts are not suitable for mobile environments because of low readability and lack of interactive interaction. Even though HTML is an essential language in a mobile environment, electronic document based on PDF is still used as it has a content integrity verification feature with a digital signature. It means that a user is sacrificing user experience in a mobile environment for content integrity and using paper-layout electronic documents. In this research, we design the Document HTML specification by setting the Document HTML conformance, adding the extended meta tags, and signing the message digest with a digital signature based on public key infrastructure (PKI). Furthermore, we implemented the Document HTML system, which has REST API services to generate and verify the Document HTML, and did experimental verification of the theory. As a result, we have confirmed that the Document HTML has both content integrity and user experience on mobile. Furthermore, the Document HTML is expected to be an alternative document format to deliver personalized content from an enterprise to a customer in a mobile environment instead of the paper layout electronic document such as PDF.

The modern government's role: As an enterprise (To be efficient and effective.); as a service and information provider (government processes that are unique to government). The modern government's role demand interoperation. The Web services architecture is based upon the interactions among three components: Service provider, service broker and service requestor. Service broker is sometimes referred to as service registry. The interactions involve publish, find and bind operations. The paper introduces the concept of web services as a way to realize interoperation between distributed applications. The paper addresses interoperation between e-government and citizen. The motivation of this work was to determine the potentials of the Web services technology for an interoperability infrastructure for e-government. In many countries, the traditional governments have many problems that stem from both insufficient and improper use of ICT. "Insufficient use" refers to the traditional means such as manual archiving systems. "Improper use", on the other hand, refers to the lack of an interoperability infrastructure within and among the government agencies. In this work.

This study proposed the approaches to business process redesign and business network redesign in e-business environment through the case analysis of e-Transformation performed in Kolon Gloteck, Inc. which has been managed and operated in a traditional mode. The proposed e-Transformation approaches of the traditional firm in this study were as following: 1) Network-focused business process redesign; 2) Introducing ERP(Enterprise Resource Planning) as e-Business backbone; 3) Establishing transparence of business functions through using shared database; 4) Understanding customer and constructing IT(Information Technology) infrastructure for customer satisfaction; 5) Performing data and process standardization; 6) Applying the best suitable IT(Information Technology) such as JSP(Java Server Pages) and VPN(Virtual Private Network). The findings of this case study are thought to be useful as a practical guideline in carrying, out e-Transformation of the typical traditional firm and to provide significant basis for constructing the theoretical framework of e-Transformation methodology.

There are many studies on the project planning, project management and quality management. The cost of the new project takes only 20% of system's lifetime resource and the costs of the maintenance and infrastructure take more than 80%, so the study on the maintenance is much more important than the study on the new project. There has been many studies on the economic life cycle of the system using it's maintenance cost, but no studies on it's infrastructure cost. This paper provides how we can adapt infrastructure cost, which takes more than 40% of system's life cycle cost, to the economic life cycle of the system and its effects on the system's economic life cycle.

IT governance is an integral part of enterprise governance and consists of the leadership, organizational structures, and processes that ensure organization's IT decision making for achieving organizational goal. Most firms have failed to resolve the balance in building IT governance. The challenge is to align IT strategy with business strategy in establishing and implementing effective IT governance. The purpose of this study is to find out the relationship between IT governance implementation factors and IS effectiveness, and the moderating effect of strategic alignment of IS strategy with business strategy on IS effectiveness. IT governance implementation factors consist of IT vendor management, IT human resource management, and IT infrastructure. Strategic alignment was measured as the alignment between business strategic orientation and IS strategic orientation that used in the research of Chan et al.(1997). In the relationship between three IT governance implementation factors and IS effectiveness, the results of multiple regression analyses showed that IT human resource management is an important determinant to influence IS effectiveness. The additional analysis using multiple regression showed that strategic alignment of IS strategy with business strategy has moderated the relationship between IT governance implementation factors and IS effectiveness.

The primary objective of this research is to explain how to implement the Service Oriented Architecture (hereafter SOA) enabled Enterprise Resource Planning (hereafter ERP) system successfully for service industries. An implementation of the ERP system help many organizations to alleviate the difficult job of supporting inflexible or legacy systems that in most cases result in cost increases, data redundancy and inaccuracy, and various inefficiencies. However, the ERP system is losing its market share rapidly to the cloud computing system which utilizes the Software-as-a-service (hereafter SaaS) and SOA. The SOA is an approach to integrate various types of IT resources to leverage existing ERP system, while at the same time building an infrastructure that can readily respond to new business environment and offer new dynamic applications. The companies that implement this system have less of a need for the kinds of all-in-one ERP system that have dominated the back office for decades and can move freely to best-of-breed applications. This research will identify the benefits and costs of the SOA enabled ERP system through case studies and its impact on competitive priorities such as cost, quality, delivery, and flexibility.

In this paper, we propose a secure communication framework for interaction and information sharing between a server and agents in DS-NVSA(Detection System of Network Vulnerability Scan Attacks) proposed in〔1〕. For the scalability and interoperability with other detection systems, we design the proposed IDMEF and IAP that have been drafted by IDWG. We adapt IDMEF and IAP to the proposed framework and provide SKTLS(Symmetric Key based Transport Layer Security Protocol) for the network environment that cannot afford to support public-key infrastructure. Our framework provides the reusability of heterogeneous intrusion detection systems and enables the scope of intrusion detection to be extended. Also it can be used as a framework for ESM(Enterprise Security Management) system.
