The korean high speed train(350km/h), composed of 7cars that are 2 power cars, 2 motorized car and 3 trailer cars, has been developed and is under on-line test. To verify the design requirements about the functions and traction performances of this train, KRRI(Korea Railroad Research Institute) decided to evaluate traction performances of the train during on-line test. For this purpose, such as torque, velocity, voltage and current, must be measured. KRRI has developed the measurement system that can be measured vast and various signals effectively. In this paper, we introduce traction performances of korean high speed train. The traction measurement items are focused on the verification of motor block performances.

This paper exploited the data reported in BK21 program of professors' research performances and analyzed the effects of reputational concerns on professors' research performances. According to the established theory of reputation effects in incentive provision, a professor's research incentive gets stronger if one's ability is less known, and one's colleagues' abilities are better known. We confirmed this theoretical hypothesis of reputation effects. Moreover, we found that a professor's research incentive was larger under inter-generational grouping in terms of age distribution and homogeneous grouping in terms of ability uncertainty.

The accelerating adoption of BIM (Building Information Modeling) is challenging collaboration practices established in the construction industry. The implementation of BIM involves changes in participants work, organization, processes and collaboration methods. Therefore there is a need to be able to measure effectively and accurately collaboration, in order to analyze and determine current practices and their performances in organizations (company, team project) as well as changes required. Previous researches scope from evaluating BIM maturity of an organization to BIM collaboration requirements but lack of proper tools and methods to analyze collaboration performances. This is especially true when it comes to evaluate the efficiency and collaboration performances of processes rather than systems or organizations. Thus this research aims to analyze systematically and comprehensively previous researches proposing diversified methods to evaluate BIM performances and collaboration. Furthermore it aims to suggest key indicators to evaluate collaboration performances of processes and project organizations. This research may contribute to better understanding of collaboration performances within organizations using BIM and further development of evaluation method for analyzing BIM design project.

Our goal of this study is to confirm whether manufacturing companies' practicing JIT production system have positive effect on production performances and to confirm that manufacturing companies' practicing SPC shows positive moderate effect on the relation between practicing JIT and their production performances. Based on empirical study to manufacturing companies nationwide, we can conclude that taking JIT practices of sample companies has positive effect on production performances and, moreover, practicing SPC has positive moderate effect on the relation between JIT practices and production performances. These conclusion represents managerial implication that concurrent practicing JIT and SPC could generate more improved production performances.

As a means to address the modes of developing institutional evaluation system aimed at improving performances of GRIs, this study looked into the influential relations where institutional evaluation system has an impact on receptivity of evaluation outcomes and performances of institutes optimize their performances. After making analysis, it was confirmed that the National Research Council for Economics, Humanities and Social Sciences' institutional evaluation system for GRIs had a positive (+) influence on performances of research institutes, and receptivity of evaluation outcomes is related to performances of research institutes. In addition, it was also confirmed that institutes with high performances, in general, have high level of receptivity of evaluation outcomes along with positive recognition of institutional evaluation system. However, weaknesses of the Council's institutional evaluation system for GRIs resulted in low level of receptivity amongst GRIs, and thus there is limitation on the government and the Council in the active utilization of evaluation outcomes. Finally, it addressed the limitations and areas for improvement in relation to research outcomes.

The purpose of this research is to understand the effects of Quality Management Award on stock prices movement and to examine the comparative advantages of quality award system in Korea and the U.S. This study compares the performances of QM Award companies in the stock market with those of the market index in both countries. We develop Korean Quality Award Index(KQA Index) based on the Baldrige Index of NIST in the U.S. We inspect three studies. Study 1 tests if the performances of MB Award winners and S&P500 index have a difference in the stock market. Study 2 tests if the performances of KQA winners and KOSPI(Korean Composite Stock Price Index) have a difference in the stock market. Study 3 tests if the performances of KQA winners and MB Award winners have a difference in the stock market. From the empirical tests, the performances of KQA winners are superior to those of KOSPI and the performances of MB Award winners are superior to those of S&P500 and the performances of MB Award winners are superior to those of KQA winners.
