According to Korea Federation of Small and Medium Enterprises (SMEs)' report, SMEs account for 99% and number of SMEs workers account for 87% in Korea. Thus, SMEs has an important role in the future Korean industry. This paper considers the improvement methods of SMEs' quality competitiveness. For this study, we developed the quality measurement model for identifying SMEs' quality level and investigated many companies by survey and interviews. We also performed the benchmarking study and the gap analysis between Korea and other countries. This paper suggests some policies for increasing the quality of SMEs.

This paper presents a practical methodology for realistic simulation on reverse characteristics of Wide Bandgap (WBG) SiC and GaN p-n junctions. The adjustment on certain physic-based model parameters, such as the trap density and photo-generation for SiC junction, and impact ionization coefficients and critical field for GaN junction are described. The adjusted parameters were used in Synopsys Medici simulation to obtain a realistic p-n junction avalanche breakdown voltage. The simulation results were verified through benchmarking against independent data reported by others.

This paper attempts to show how DEA(data envelopment analysis), a nonparametric productivity analysis method, can be employed for insurance companies to improve their respective efficiencies and competitiveness. Specifically, we measured relative technical efficiencies and returns to scale of 11 Korean property-liability insurance companies using BCC model, and raised several issues including the cause of inefficiency, benchmarking toward reference set and resource allocation concerning the insurance companies. Also, in order to monitor the variability of the research results over periods, we employed longitudinal analysis to see the moving patterns of technical efficiencies, returns to scale and frequencies included in the reference set of the individual insurance companies under consideration. The methodology and the results in this paper may also serve as a useful guideline for individual insurance companies to set their respective business strategies.

We attempted to empirically analyze the supply chain performance of Korean companies. We utilized the supply chain performance metric of SCOR(Supply-Chain Operations Reference-Model) which has been developed by the Supply Chain Council. We especially focused on the supply chain asset performance using the currently available accounting database of Korean companies. Cash-to-cash cycle time, inventory days of supply, and asset turns were analyzed for 621 Korean companies during the last 5 year period 1997-2001. We compared the performance by industry type and company size. In addition, we compared the cash-to-cash cycle time of Korean companies with global companies.

This study examined the definitions and characteristics of TQM, procedures, problems and benefits of TQM and investigated the cases in U.S.A. and U.K. in a n.0, pplying TQM to libraries. It is necessary that libraries and information centers should a n.0, pply TQM for management innovation in order to overcome present and future crisis. As a result of study, there are three suggestions as follows. First, To be developed the TQM model for various types of libraries by national or library world. Second, To conduct TQM successfully in libraries and information centers, it is necessary to comprising the elements as follows. 1) Vision, committment and leadership of top management 2) Change of library's organizational culture 3) Learning and training of organizational members 4) Interests and participation of organizational members 5) Empowering and respecting people 6) Rewards for performance and accomplishments 7) Benchmarking 8) Measurement of performance and benefits. Third, TQM activities in libraries are developed into quality movement.

This paper investigated the efficiency of automobile firms by using several non-parametric approaches. First, using Data Envelopment Analysis (DEA), the paper has investigated the critical factors that determine the relative efficiency of management performance in automobile companies. Second, we examined how the firm size impact on the difference of this efficiency by using Kruskl-Wallis Test. Third, by using Mann-whitney test, we also investigated the difference of the efficiency accoss existence of technological innovation activity. Finally, the paper explored the relationship between technological innovation and management efficiency by using logistic regression model. The findings of this study provided practical information for inefficient automobile firms to find benchmarking firms and strategic position to improve their efficiency. The result also provided theoretical and methodological implications for those who explore factors affecting management efficiencies. Future research directions with the limitation of the study are discussed.

As an interest in the efficiency of public sector expenditures has spread across the world, Korea has operated a self-evaluation system for government projects as a part of the performance-based budget system. However, an evaluation system for public information technology project has been criticized for its lack of validity, which stems from the uniformity of performance management. This study draws insight from knowledge management literature in an attempt to address the problems with the extant performance evaluation system in public agencies. To realize benefits from IT investment, an agency needs to develop its own performance management model for information systems projects, with a focus on the interaction of IT and organizational system. The knowledge management-based framework for IT projects was verified through a case study, with which we discussed the applicability of knowledge management to the evaluation of public information systems projects.

Information and communication industry, which shows rapid growth rate, is now leading the global economic growth, contributing a ripple effect on general business and economic structure. It is said that information and communication industry enables swift economic growth taking a role as a basic industry of information-oriented society. Especially, rapid technical innovation promotes mutual growth of other related industries and it is technology-intensive. The purpose of this research is to analyze the management efficiency of information and communication industry using DEA method, and finally suggest numerical value for inefficient organizations to improve their efficiency. CCR-I, BCC-I efficiency and RTS(Returns to scale) of 29 companies engaged in information and communication industry was evaluated. With the results, I suggested model companies for benchmarking in information and communication industry. To summarize, 7 companies were selected with CCR-I efficiency rate 1, and 12 companies with BCC-I efficiency rate 1. RTS was finalized with 8 IRS companies, 10 DRS companies, and 11 CRS companies.

Analyzing the productivity has been widely applied in economic analysis and of the key concept of utility regulation. In this paper we use benchmarking technique known as Data Envelopment Analysis (DEA) model to analyze the productivity. And we show that from the result it is possible to evaluate the performance of inefficient firms by reducing their input levels.
