Object-oriented Process Engineering for Decentralized Organizations
The Journal of Information Systems, volume 6, issue 1, 1997, Pages 5~26
The demands for continuous process optimization require a radical rethinking of how information systems are designed and constructed. Information systems must be capable of sustained, graceful change in response to evolving business requirements. This proposition is supported by the fact that information systems have helped increase productivity only when they were built to support new and better ways of conducting the business. In such context, business process engineering (BPF) is recognized the first but most critical stage in developing information systems as well as in launching business improvement and innovation projects. However, more often, there exist great gaps and inconsistencies between the results of BPE and the business itself, which turn into huge maintenance overhead during an information system lifecycle. In order to solve such an ever lasting problem, this paper orthogonal models, procedure, guide, and work flow are constructed in our engineering discussions focus on decentralized organizations, the method is general enough to be applied easily to other types of organizations without difficulties.

Influence of Adoption of Information Technology on the Change of Organization Structure
The Journal of Information Systems, volume 6, issue 1, 1997, Pages 47~62
Adoption of information technology(IT) in a corporation has been started with the aim of efficient process and management of business being complicated. But, this adoption of IT is roleplaying the rearrangement of organization structure. Many researchers have studied the relationship between adoption of IT and change of organization structure. In this research, it has been studied that how the adoption of IT influences on the change of organization structure. Adoption of IT ina corporation influences the structure of manpower and this influence causes the change of structure of organization. However, this influence is not only the deterministic source to the change. In a corporation, not only intention and role of chief executive and but also participations of employees for the adoption of IT make differences in the quality of corporation information systems and, as a result, the aspect of organization structure change.

Buffer Invalidation Schemes for High Performance Transaction Processing in Shared Database Environment
The Journal of Information Systems, volume 6, issue 1, 1997, Pages 159~180
Database sharing system(DBSS) refers to a system for high performance transaction processing. In DBSS, the processing nodes are locally coupled via a high speed network and share a common database at the disk level. Each node has a local memory, a separate copy of operating system, and a DBMS. To reduce the number of disk accesses, the node caches database pages in its local memory buffer. However, since multiple nodes may be simultaneously cached a page, cache consistency must be ensured so that every node can always access the latest version of pages. In this paper, we propose efficient buffer invalidation schemes in DBSS, where the database is logically partitioned using primary copy authority to reduce locking overhead. The proposed schemes can improve performance by reducing the disk access overhead and the message overhead due to maintaining cache consistency. Furthermore, they can show good performance when database workloads are varied dynamically.
A Study on the Classification Framework of Information Services
The Journal of Information Systems, volume 6, issue 1, 1997, Pages 181~221
In order to provide effective information services in a province, we should first select vendors who enable to meet end-users' needs and develop information services for the sake of end-users. Cases, policies, technological and legislative issues in information services have been researched well. But no research has been done on potential information services in the future and their classification. In this study, based on literature survey, future information services are gathered, described, and classified with respect to the needs of end-users, and finally a framework for the classification of information services is developed. This framework can be used as a criterion to select, with a priority, information services to be provided in province through the information super highway. The framework will contribute to accomplishing the effective use of information resources in the province, and eventually balancing the level of information utilization between provinces.
Development of Inventory Control System for Large-scale Retailers using Neural Network and (s*,S*) Policy
The Journal of Information Systems, volume 6, issue 1, 1997, Pages 223~256
Since the business scales of retailing companies become to be very large and the number of items dealt increases explosively, automation of inventory management becomes one of the most important issues to solve in retailing industry. In order to accomplish this automation of inventory management, there must be a great need to a method which can perform real-time decision making on inventory control in an automatic fashion, while communicating with inventory information systems like POS system and automatic warehousing system. But even in this circumstance, there are also many obstructions to such automation like varying demands, limited capacity of warehouse and exhibition room, need for strategic consideration on inventory control, etc., in a real sense. Due to these reasons, it seems very difficult that most large-scaled retailing companies get fully automated inventory management system. To overcome those difficulties and reflect them into inventory control, we propose a automated inventory control methodology for retailing industry based on neural network and policy model. Especially, policy model is devised to deal with dynamic varying demands and using this model, strategic goals on inventory can be considered into inventory control mechanism. Our proposed approach is implemented in workstation and its performance is also empirically verified also against to real case of one of the major retailing firm in Korea.
An Empirical Investigation for EIS Utilization:On the Basis of TAM

Today, executives in the company operate their organizations under highly competitive environments with dynamic technological, economic, and political changes. Under these new environment changes, they play the important role in establishing the future directions and strategic orientations of organizations. In general, executive information systems (EIS) are designed to support these roles of executives. They can help executives access and use the information they require about the organization's internal and external environments. In spite of such potential EIS support for executives, only a limited number of empirical studies have been published in this area. by employing a well-established theory of computer usage behavior (Technology Acceptance Model : TAM), this study systematically investigates the key factors in the successful utilization of an EIS. The empirical results from this study may prove useful for both IS researchers and practitioners.
