This study intends to find the empirical relationship between the environmental and organizational characteristics and the strategic use of information systems(SUIS). Sixty-five firms in Korea are surveyed and analyzed to understand the impact of these characteristics on SUIS. As environmental characteristics, we select dynamism, hostility, and heterogeneity. As organizational characteristics, we select centralization, formalization, and IS maturity. The result of correlation analysis shows that formalization and information systems maturity are correlated significantly with SUIS. The result of regression analysis reveals that formalization is a major determinant to influence on SUIS of organization. Also, additional analysis shows that service industry have higher extent of SUIS than manufacturing industry.

This paper proposes a hybrid intelligent system that predicts the failure of firms based on the past financial performance data, combining neural network and rough set approach, We can get reduced information table, which implies that the number of evaluation criteria such as financial ratios and qualitative variables and objects (i.e., firms) is reduced with no information loss through rough set approach. And then, this reduced information is used to develop classification rules and train neural network to infer appropriate parameters. Through the reduction of information table, it is expected that the performance of the neural network improve. The rules developed by rough sets show the best prediction accuracy if a case does match any of the rules. The rationale of our hybrid system is using rules developed by rough sets for an object that matches any of the rules and neural network for one that does not match any of them. The effectiveness of our methodology was verified by experiments comparing traditional discriminant analysis and neural network approach with our hybrid approach. For the experiment, the financial data of 2,400 Korean firms during the period 1994-1996 were selected, and for the validation, k-fold validation was used.

ERP is now one of the prevailing applications for integrated information systems, So far, the conventional ERPs lack how to manage knowledge of making decisions, that is one of the important goal of ERP. This gives a motivation on adding decision support capabilities to the ERPs: active advice for business analysis, evaluation and control. In this paper, we proposed an agent-based intelligent ERP that is operated on the Internet. In special, knowledge of economic value added (EVA) is explicitly acquired as a set of data, models and methodologies, A new knowledge representation format, MIF, is suggested to show the communication mechanism between agents, The agent-based knowledge processing is adopted to deliver intelligence on the Internet.

The purpose of this study is to determine whether the centralization of information technology activities and the organizational structures, especially the centralization of decision making and the complexity have any effects on the information systems performance. The strategic types, the formalization dimension of organizational structures, and the industrial characteristics, which might have impacts on the dependent variables were controlled. Information systems performance was measured by both user satisfaction and organizational performance. To achieve the research objective, a field study using the structured questionnaires was employed. Thirty large companies participated in this study. Multivariate regression analysis was used to analyze the data collected. Findings of this study are summarized as follows: The centralization of IT activities, the centralization of decision making, the complexity of organizational structure and the interaction effects among these independent variables all turned out to have statistically significant effects on the user satisfaction, while not on the organizational performance. The implication of these findings is that the IT structure must be determined in congruence with the organizational structures and vice versa. One weakness of this study is that the strategic type was not an independent variable but a controlled variable. Further study of using the strategic type as an independent variable with more sample corporations is to be encouraged.

Intranet is information technology for information sharing and collaborative work in geographically dispersed organizations, and has clear potentials to combine with other information technologies such as data warehousing and knowledge management. Data warehousing make it possible that the data stored for business analysis can most effectively be accessed by separating it from the data in the operational systems, and knowledge management is the paradigm to make the enterprise realize the best value of its knowledge assets, This paper is to suggest an architecture of knowledge sharing to combine knowledge management with data warehouse under the Intranet environment for the purpose of achieving the competitive advantages through the effective decision making in the modern companies, This paper also addresses the steps to implement this architecture.

This paper describes a personalized advertisement technique as a part of intelligent customer services in Internet shopping malls. Based on customers' initial profile, purchase history, and behaviors in an Internet shopping mall, the technique displays appropriate advertisements on Internet web pages when customers' visit to the shopping mall. Customers preference scores for product groups which are main sources to select advertisements, are stored either a preference table or preference trees. Both of the two storage methods can support selection of advertisements on real time, and the preference tree method can reflect affinity among product groups. The suggested technique selects different advertisements to reflect changes of customers preferences as time goes by. An experiment has been performed to evaluate the effectiveness of the algorithm, which revealed that the algorithm selects more customer-oriented advertisements rather than random selection.

The increased investment in technological innovations makes the investigation of factors affecting technology adoption more interesting. Several perspectives have been proposed to explain the determinants of information technology adoption. While the traditional innovation diffusion research streams try to explain and predict adoption behavior with the adopter's perceptions about the characteristics of the innovation itself, critical mass theorists argue that adoption behavior as a collective action is based on what their business partners are doing and whether there exists enough critical mass to justify the investment. Drawing on theses two perspectives, this study investigates the decision criteria in the adoption of information technology as innovation and factors affecting the decision criteria. The survey results reveal that the adoption behavior is affected both by innovation characteristics and by critical mass's activity. Correlation analysis, t-test, and stepwise regression models also show that as the environmental uncertainty is getting higher, adoption decision is affected more by what others are doing, and that highly competitive organizations seem to play the role of critical mass.

The objective of this research is to develop education and training systems for IS department and user department personnel, which is essential to effective implementation IT(information technology) strategies in most of organizations. In order to achieve this research objective, first this study theoretically derives six categories of education and training based on comprehensive review of the previous research, and explicates concrete items for each category. And then, with respect to each of these items, we empirically investigate the degree of necessity measured by the gap between the required level of knowledge and skills which staff members should have for effective implementation of IT strategies and the present level of them which they really have. Field survey is employed for the data collection: 270 questionnaires are distributed to the companies in private and public sectors, and 196 questionnaires are collected in useful condition and are analyzed. The findings of this research shows that six dimensions of education and training are empirically derived by factor analysis as following: (1) general knowledge for organizational overview, (2) management knowledge and skills, (3) knowledge and skills of the specific information system which IS department and user department personnel are directly involved in developing and operating, (4) knowledge and skills for strategic use of IT, (5) general knowledge and skills for IT and (6) advanced expert knowledge and skills for specific IT. And the degree of necessity turns out to be statistically significantly different among six dimensions of education and training needed by IS department and user department personnel respectively. Also for each dimension, the degree of necessity is shown to be statistically significantly different between IS department and user department personnel The results of this study can provide the theoretical basis for constructing the IT education and training system for effective implementation of IT strategies, Also they can be used as a practical guideline in developing and promoting specific IT education and training programs in real organizations.

MIS personnel should not only be capable of developing technically sounded systems, but also act as the companion role of strategic management. For this reason, it is important to direct efficient human resource management for MIS personnel. For directing efficient MIS human resource management, this paper studies the relationship of major types of MIS career orientation, job satisfaction and organizational commitment based on the work area of MIS personnel, Based on the empirical analysis using questionnaires answered from MIS personnel of Korean public and private enterprises, the hypotheses of this study were proved. The result of this research shows most of the domestic MIS personnel tends to line up with technology and management favoritism for their career orientation. If an individual career orientation and his or her work area are matched, it presents higher job satisfaction. Furthermore, a group of management orientation shows higher organizational commitment than a group of technology arientation among MIS personnel with identical job satisfaction. Therefore, this study suggests that career orientation of MIS personnel affect the job satisfaction and organizational commitment. In the future, a career management system suitable to the MIS personnel should be developed to improve the effectiveness of MIS organization.

This study presents an information security level index and a quantification scheme. A comprehensive survey on previous researches in information security checklists has been performed. A candidate indicator list for information security level has been developed, Desirability of each indicator has been tested by 4 criteria, They are general validity, relative importance, probability of accident and impact of accident. 67 experts' opinion has been collected and analysed. The result shows that selected indicators are a very good candidate set for the determination of information security level. A factor analysis shows indicators are well structured. There exists strong correlation between validity and probability, validity and impact, and importance and probability. A quantification scheme of information security index has been developed by experts' judgement and statistical tests.
