  • In digital economy, information systems are recognized as the most critical survival factor of companies. Companies must launch and expand business based on information systems either developed newly or adopted as ERP. However, successful information systems operation shall face many realistic problems. Especially most small and medium enterprises experience many difficulties in systems operation or even give up operating information systems due to unexpected operational problems. This paper suggests a framework for effective information systems operation for small and medium enterprises. The framework is designed through case studies, consisting of service framework, auditing framework, and risk management framework. It is expected that the framework contributes to successful information systems operation in small and medium enterprises.

  • The purpose of this research is to develop an estimation model for information systems operating costs. Current cost estimation practices and types of sytem management projects have been reviewed an analyses. Typical operating project types of information systems are determined. They are application system operation, help disk operation, network management and operation, and hardware management. For each type of projects, cost factors ar identified and a structure of cost estimation model is defined. Cost estimation models have been constructed and tested by 24 real operation projects data. Statistical analysis shows derived models are statistically significant. User groups' opinion on these draft cost estimation model has been surveyed and summarized. The results of this research can be used as a cornerstone for future research on operating cost estimation, and for cost estimation guideline of information systems operation projects.

  • Marketing information systems become a competitive weapon that supports firms in making decisions on the operation of marketing-related activities. However, little research regarding the operating strategy of marketing information systems has been conducted in Korea. Considering that this issue has been studied in the United States, this paper conducted a global benchmarking on the operating strategy of marketing information systems between Korean and the United States firms. The result of this global benchmarking suggests recommendations on supports from three management levels, the mix of 4P, the management of marketing, data from environment, and information sources.

  • The main subject to become a hub port is automation. The automated container terminal has already operated in advanced ports and it has been planned for the basic planning and operation design in domestic case. The key of automated container terminal is effective operation of both ATC(automated transfer crane) and AGV(automated guided vehicle) which is automated handling equipments. This is essential to productivity of automated container terminal. This study suggests the most optimal method of equipment operation in order to minimize loading time using each three types of effective ATC operation methods and AGV dispatching rules in automated container terminals. As the automated equipment operation causes unexpected deadlocks or interferences, it should be proceeded on event-based real time. Therefore we propose the most effective ATC operation methods and AGV dispatching rules in this paper. The various states occurred in real automated container terminals are simulated to evaluate these methods. This experiment will show the most robust automated equipment operation method on various parameters(the degree of yard re-marshaling, the number of containers and AGV)

  • In this study, industry-specific application systems operation cost estmation models are suggested. We reviewed operation cost models of previous researches, and developed a strong need for industry-specific operation outsourcing cost models. Security industry operation cost model and medical care industry outsourcing cost model are proposed, and tested with empirical data. We showed the validity of industry-specific application systems outsourcing cost models. Future research will be needed to develop outsourcing cost models for other industries and to refine cost models developed in this study.

  • The counter-fire operation system performs its mission exchanging information with other related systems such as command & control systems and military information systems. In the process of exchanging information, the counter-fire operation system uses a type of data message which contains exchange data information in the format of KMTF. The requirement of data exchange of count-fire operation will continue to evolve. But the EDX(External Data eXchange) configuration item of the current counter-fire operation system can not effectively cope with the variation of data exchange requirements due to its fixed software structure. In the paper, a solution for improving flexibility of external data exchange in counter-fire operation system is proposed.

  • The overall objective of this study is to empirically investigate organizational/managerial factors affecting system development team operation. The contributions of this research project are two-fold. First, this study examined various organizational/managerial factors that made team operation successful. Second, we presented the key success factors among the identified success factors of team operation. A field investigation of 68 system development teams located around YoungNam area indicates that motivation, leadership and egalitarian team culture are success factors of team operation. Especially, key success factors are leadership and egalitarian team culture.

  • Application systems outsourcing is an important part of IT outsourcing services. Application systems outsourcing costs is determined by service levels of outsourcers. Recent researches show there is a strong need to build industry-specific cost estimation models. In this study, an industry-specific application systems operation cost estimation model is suggested. We reviewed operation cost models of previous researches, and proposed a cost estimation model for security industry. Industry-specific service factors are defined and service levels are determined by Interviews with experts. The proposed model is tested and adjusted with empirical data. The new model shows more accurate prediction than previous general models. Future research will be needed to develop outsourcing cost estimation models for other industries and to refine cost models developed in this study.

  • These days, a lot of information and knowledge is being produced and accumulated constantly, which makes it difficult for a person to get the exact information or knowledge in simple way that he or she wants to get. It is also true in college and university. A lot of data is increasing so fast that a student cannot achieve his or her goal in learning with the text. This means that it is necessary to bring a change in the way of teaching and learning from only simple lectures. So in this treatise, we try to develop the method of the introduction and operation of center for teaching and learning. In order to accomplish the purposes, this research has examined the questionare and domestic colleges and universities.
