As subsriber's requirements for high quality of telecom service are increased, a telecommunication network becomes complex and huge, and its management becomes an essential and an important factor in the evolution of telecommunication networks. In this paper, we focus on the network performance management and discuss the strategy of near real-time performance evaluation and control in Korea Telecome (KT) networks.

This paper focues on development and implementation of a perfomance management algorithm for IEEE802.4 token bus networks to serve large-scale integrated manufacturing systems. Such factory automation networks have to satisfy delay constraints imposed on time-critical messages while maintaining as much network capacity as possible for non-time-critical messages. This paper presents the structure of a network performance manager that possesses the knowledge about perfomance management in a set of fuzzy rules and deriving its action through fuzzy inference mechanism. The efficacy of the performance management has been demonstrated by a series of simulation experiments.

This study bridges the gap between management accounting, CG and entrepreneurship disciplines. Unlike previous studies, this study adopts a positivist approach to develop a contingency framework of CG that operationalises the conformance and performance dimensions into measurable constructs. The contingency framework also adopts a holistic approach that investigates the interrelationships between VBM, CG and CE, as important predictors of organizational performance, which can provide insights into the complementary or conflicting relationships among these predictors in their effects on organizational performance.

As electronic commerce under the digital economy environment evolves rapidly affecting the structure of our economy and individual life styles, the need for metrics system to evaluate the performance of electronic commerce activities remarkably increases. Reviewing the characteristics of electronic commerce and some issues related to its measurement, this paper proposes a framework to measure the performance of electronic commerce business activities. the proposed framework customizes the balanced scorecard method for electronic commerce practices and can be applied effectively to electronic commerce businesses as an appropriate measure.

The purpose of this study was to develop indicators for quality management of educational institutions, and to achieve this, literature analysis and expert interviews were conducted. Through literature analysis, the components of TQM were derived focusing on factors to improve the quality of education, engineering education accreditation standards, and a representative education accreditation system, were considered. Additionally, seven areas as well as 32 indicators required for education quality management, were derived by comparing the EFQM excellence model and the MBNQA education model, applied for quality management of companies and institutions. By comparing and synthesizing these results, a draft was developed for the quality management index of educational institution. Next, opinions on correction and supplementation of quality management indicators derived from literature analysis, were collected from five education experts. From the comparisons and integration of these results, eight criteria (leadership, strategy, customers, people, facilities and environment, curriculum management, curriculum improvement, and performance management) and 34 indicators, were proposed for quality management indicators for educational institutions. Curriculum management, people, and performance management criteria were considered more significantly in quality management of educational institutions, and several implications are suggested based on the study results.

Drawbacks of using sigma level as a performance metric is reviewed. The concept of sigma level is introduced and methods of calculating sigma levels for various cases are illustrated with examples. Drawbacks of using sigma level as performance metric are also discussed with some suggestions for overcoming them.

In this study, empirical studies are conducted not only to investigate the effect of the quality of accounting information system on management performance but also to study whether user satisfaction and education training achievement play a mediating role in the relationship between the quality factors of accounting information system and management performance. To this end, a research model is established to verify the mediating effects of user satisfaction and education training achievement as well as the effect of the quality of accounting information system on management performance. We conduct a questionnaire survey on users of accounting information system of companies. The results of the empirical analysis based on the survey data are summarized as follows. First, the quality of information system has a positive effect on educational performance and user satisfaction, but not on business performance. Second, user satisfaction and education training performance play a mediating role in the relationship between the quality of information system and management performance. The results of our research show that it is necessary to educate and to train the employees in order to make the accounting information systeme to contribute management performance and to control continuously the quality of the information system in order to improve user satisfaction.

Cooperative and integrative partnerships between buyers and suppliers are very important for effective operations. Such partnerships should be based on various information technologies developed in recent years. Therefore, we investigated the relationship among IT performance, IT infrastructure and supply chain performance in buyer-supplier linkage using exploratory examination. This analysis is based on survey results of buyer-supplier practitioners in Korean electronics industry. Specifically, we used factor analysis, correlation analysis, and regression analysis. Major findings are as follows. First. buyers' IT performance contributed to enhance their operational & financial performance, and satisfaction. Second, buyers' IT infrastructure improved their financial performance and satisfaction but showed mixed effects on operational performance. Third, suppliers' operational performance enhanced buyers' operational & financial performance, and satisfaction. Fourth, suppliers' IT performance strengthened their operational & financial performance, and satisfaction. Fifth, suppliers' IT infrastructure showed positive relationships with operational performance and satisfaction.
