Interest in EA has been Increasing recently, however, with the coming into effect from July 2006 of the 'Information Technology Architecture Act' which requires the public sector to adopt EA. Until now, the study of EA has been focused on concepts and methodologies for the adoption of EA. The fundamental issue, however, the study on the factors affecting the adoption of EA, has rarely been explored. This thesis therefore surveyed which factors have affected the adoption of EA. The analysis found that the adoption of EA was affected by the external environmental characteristics such as rules or regulations and the level of competition in the Industry concerned, and by the organization's information technology level. However, technological aspects such as perceived usefulness or perceived ease of use - traditionally considered as critical factors in adopting information technology - were found to be less influential. These results show that in Korea we still do not regard EA as a method of optimizing the IT resources of a company. In order for EA to be widely adopted, therefore, we should Put primary emphasis on efforts to properly appreciate its technological aspects, such as its technological usefulness or convenience.

The study focuses on EA experiences of Korea in public sector in terms of three distinguishing periods: preparation, adaptation, and utilization. Analyzing those experiences would lead to understanding of EA performance in Korea, and to derivation of future policy directions. EA efforts of Korea shows results in several areas, especially in prevention of duplicative investments, savings in IT expenses, and optimization of information resource management. The study suggests sustainable strategy for futre EA growth.

This paper addresses the issue of workflow on Grid and P2P, and proposes a layered workflow architecture and its related workflow models that are used for not only distributing workflows' information onto Grid or P2P resources but also scheduling the enactment of workflows. Especially, the most critical rationale of this paper is on the fact that the nature of Grid computing environment is fitted very well into building a platform for the maximally parallel and very large scale workflows that are frequently found in very large scale enterprises. The layered architecture proposed in this paper, which we call Enterprise Workflow Grid Architecture, is targeting on maximizing the usability of computing facilities in the enterprise as well as the scalability of its underlined workflow management system in coping with massively parallel and very large scale workflow applications.

The CMIP(Common Management Information Protocol) and SNMP(Simple Network Management Network) are the two major network management protocols, Which nee to be integrated. Since the networks need to be managed in a uniform way, the CORBA(Common Object Request Broker Architecture) NE View is to develop as a Standard in the ATM Forum For the TMN management structure to integrate these two protocols. In this paper, the function classes are defined to develop the gateway for efficient subnetwork management. The function classes are defined based on the analysis of EMS functions which are mainly network management design of the TMN structure. Also, the object models of the SMI)(Structure of Management Information) in SNMP and the GDMO(Guidelines for the Definition of Managed Objects) in CMIP are developed way direct translation and abstract translation. The integrated management system design, information model translation of EMS using classdefinition, is efficient is efficient method to interconnect CORBA/SNMP and CORBA/CMIP.

A Systematic Wealth Management Framework (SWMF) was developed as a private banking management tool to enable more integrative personal finance management of personal wealth. It is a reference model that provides an unified framework for development, operation, and management and makes provision for personal financial services in today's complex financial environment. This study suggested some practical results from banks and insurance companies that have established SWMF as the differentiation business strategy for wealthy customers. The focus of this manuscript is on capturing the methodological approach most financial institutions in Korea adopted to execute new e-finance planning and implementation based on the SWMF. The alignment between the wealth management business goals and information system architecture at an organization constitutes the main theoretical basis of the study. Relevant discussions are made on the wealth management framework as a general business model for financial industry, on the functional relationship between new information systems and business organizations. Finally, lessons learned from the SWMF implementation are discussed.

In this article we review the metaphor of service-oriented architecture for enterprise computing. In typical definitions service-oriented architecture appears as a single message and a consistent roadmap for building flexible software system landscapes. But it is not. Different communities have elaborated different SOA (service-oriented architecture) concepts to address different problem areas, i.e., enterprise application integration, business-to-business, business process management, and software productizing. If software architects and software managers are aware of these strands of SOA when talking about SOA in their projects they can avoid misunderstandings and detours better. This article contributes a clarification of the different strands of SOA concepts and technologies and their mutual dependencies and identifies particular SOA concepts as instances of more general software engineering principles.

IT capability is one of the main research topics in MIS area. Given the finding that IT investment does not necessarily contribute to better organizational performance, the concept of IT capability was selected as an alternative antecedent variable for IT's effect on performance. A number of existing MIS papers have shown that firms with the high level of IT capability lead to a better performance. However, very little research has been done concerning the issue of how the IT capability could be enhanced. Recently, enterprise architecture effort has been emerged as an avenue to better IT management. This study aims to empirically examine the relationship between EA effort and IT capability.

In this paper, we propose the integrated management system for computing resource such as personal computers, the interface of router, and server equipment. IRMS defines and analyzes the performance factors for system such as pc and router, also it manages assets for server equipment. Manager can make use of data for understanding conditions whether system is normal or not. We suggest a hierarchical integrated management architecture for resolving problems of scalability and managing efficiency in large domain networks.

BTL business-related systems were developed by the Ministry of Education, Korea Development Institute, Korea Education Development Institute. These systems were effectively support to BTL projects schools that expanding in size. However, compatibility of information is difficult between systems that specific information system developed for the purpose of functional redundancy. In this study, operational readiness, facility management, operations and the assessment phase are divided in the BTL school projects process. And the business functions were analyzed in the related systems. In addition, we are contributed to improve standards and the school BTL business processes to improve the reliability of the process.

Internet attack incidents have steadily increased along with the increase in Internet users. To protect systems and networks from these attacks, advanced security systems have been developed. Now that these security systems are operating, their successful management is more important than the purchase and establishment of new information security systems. The acquisition of good systems is ineffective and financially wasteful unless they are managed properly. Adequate management policy has recently become the focus of users. In other words, for companies and educational institutions with their domains, capital expenses are enormous to bear, and good security staffs are difficult to find, for which reasons outsourcing vendors or Managed Security Service Providers (MSSPs) that manage and operate the information security systems of certain domains become very appealing. Today, customers expect ISPs to perform MSSP services that used to be carried out by the security companies. This document presents the role and necessity of ISPs as MSSPs.
