This study aims to provide the results of a case study, based on the action research approach, in which an user-oriented management system for enterprise information systems operational performance is successful developed and applied. This study performs the research and summarizes the results by adopting 5-step approach of action research, i.e., diagnosing, action planning, action taking, evaluating and specifying learning. The most important lessons learned from the study include (1) operation performance measures should be established to be shared by the management and users; (2) evaluation and improvement activities should be performed continually; and (3) formula to calculate the measure should be evolved so that improvement initiatives can be identified. The results of the study are expected to provide the companies intending to develop a management system for enterprise information systems operational performance with the practical and useful information. In addition, it is expected to suggest the research results that can be utilized as a basis for future research in this area.

Project management is critical for the success of the large and complicated IT project. Accordingly, to improve the efficiency of the project management, operation of separate Project Management Office (PMO) organization is getting important. Despite the appreciation of PMO as necessary for project success, the result has not always been positive. In this respect, we intended to formalize the PMO success model by incorporating necessary factors related to PMO services and capabilities, and their relationship. Empirical testing results verified critical antecedents comprising PMO services, which included schedule, quality, budget and others. Furthermore, moderating impacts of PMO capabilities are quantitatively assessed. The research findings offer practical insights for successful management of PMO.

The widespread use of cryptographic technologies is complicated by inconsistencies and duplication in the key management systems supporting their applications. The proliferation of key management systems or protocols also results in higher operational and infrastructure costs, and fails in interoperability. Thus, it is essential to realize key management interoperability between different and heterogeneous cryptosystems. This paper presents a practical and separable key management system for heterogeneous public-key cryptosystems. We achieve the interoperability between different cryptosystems via cryptography approaches rather than communication protocols. With our scheme, each client can freely use any kind of cryptosystemthat it likes. The proposed scheme has two advantages over the key management interoperability protocol introduced by the organization for the advancement of structured information standards. One is that all the related operations do not involve the communication protocol and thus no special restrictions are taken on the client devices. The other is that the proposed scheme does not suffer from single-point fault and bottleneck problems.

The misfortune management is basically governmental responsibility. Therefore, most of nations build the management system. The positive environments is put to practical use and the negative environments are eliminated. This thesis is studied about the special quality of disaster management and the environment factors.

The finish works of construction projects comprises approximately 40% of the total construction duration. Thus, the management of finish works have as big as impacts on total project duration as the earthworks, foundation and structure works. Process interference management is considered one of the most important issues dealt during finish works. However, it was investigated that effective management systems have yet not been applied for practical use. Accordingly, this paper suggests a mobile technology based finish works management system that mainly focuses on preventing process interference occurred due to ineffective communication between general and sub-contractors.

The purpose of this study was to develop an educational program of leadership for housewives as the CEO of household management. For this purpose, the related concepts of leadership as CEO were analyzed and cases on the educational program for housewives were reviewed. The program developed through this study consists of four subjects: 1. The housewives' identity 2. Household management and the CEO 3. The strategies for the development of leadership and 4. The connection between the individual household, the community, and society. It can be expected that the program will contribute to the activation of various programs in the Healthy Families Center and the strong positioning of research in "family resource management" as a practical science.

One of important technology that must improve compulsorily on information-oriented society stores, search and transmit cultural contents data of great quantity in heterogeneous environment. SAN appeared by solution to resolve the problem such as integration management of heterogeneous system data, effective practical use of storage, data transmission limit is happened from here. SAN is system that manage and shares data of large quantity efficiently attaching directly to high speed network such as Fiber Channel that storage system has been attached to server individually SAN became more complicated than existent storage environment although offer much advantage such as decrease of storage expense and flexibility of system configuration. This study argues management way could consider in such environment that understand complexity and component of networked storage system.

Many companies in Korea have introduced and put Six Sigma to the practical use recently, others are under consideration to introduce it. As we consider how to recognize and to apply it, we are able to know there is a difference among companies and it differently influence on those companies. In this paper, we analyze the structural differences between Quality Management and Six Sigma movements through the questiionnaire designed effectively to investigate them. We also examine the controversial points, suitability as the management model, the level of Quality Management and Six Sigma movements, and analyze how much the movements effect on the management activities. Finally, we show how to improve the Quality Management and Six Sigma movements in Korean companies.

The accumulated BMS data have made it easy to make reasonable decision-making for bride maintenance and repair work. In the developing period of BMS, the bridge management was not easy due to the lack of understanding of BMS and low credibility of the data. In recent years, it has been possible to enhance the credibility of the data and to expand the application scopes of BMS with the efforts of Local Road Construction Offices. The reasonable decision making for bridge management can improve the performance of bridges under the practical constraints such as limited budget. It can then result in the reduction of bridge maintenance budget. This study provides the methodology for the application of mobile internet-based KOBMS for bridge management. The data flow for BMS is the most important factor for decision-making on budget allocation, and this study establishes the basic scheme of the data flow for BMS. The implementation of PDA for BMS may suggest a new paradigm of 'Mobile' in the field of construction management.

In order to more effectively respond to the rapidly changing situations of domestic and foreign interior design industries and to expect their further development, not only academic endeavor but also practical one, that is, the introduction of the new interior-design management is necessary. This research aims to establish a preliminary model of interior design management conducted not by customers but by designers who understand the characteristics and structure of business environment. To achieve this, we will investigate and analyze previously suggested theories on interior design management and case examples. In doing so, we hope that this research will facilitate future researches which in turn may come up with more persuasive models of interior design management.
