  • In evaluating sound performance of building, it is important to carry on tests and evaluations based upon residential sound performances. Korean Standards include test methods on sound performance, but don't include any code on evaluation methods. Therefore, evaluation methods from Japan or ISO have been used for evaluating sound performance in domestic so far. In this study, a draft of Korean Standards on a sound performance evaluation method in buildings is proposed.

  • There have been many instances of damage to buildings with soft stories, and it is important to consider vertically irregular buildings when evaluating the seismic performance of existing buildings. However, because conventional methods do not easily reflect vertical irregularities with sufficient accuracy, it is possible to underestimate or overestimate the seismic performance of buildings with vertical irregularities. This study aims to develop a seismic performance evaluation method for vertically irregular buildings using the stiffness-based soft story ratio (SSR), which is a parameter that represents the ratio of the demand and the capacity for displacement and refers to the ratio of displacement concentration in buildings. The seismic performance evaluation method developed in this study is compared with the conventional seismic performance evaluation method for four piloti buildings, using the first-floor column as a variable. Conventional seismic performance evaluation methods often overestimate the seismic performance for models in which vertical irregularities are maximized. However, results of the proposed seismic performance evaluation method are identical to those from a detailed evaluation for all models. Therefore, it is considered that the proposed seismic performance evaluation method can provide more precise seismic performance evaluation results than conventional methods in the case of piloti buildings, where vertical irregularities are maximized.

  • The quality of performance evaluation on engineering consultants that provide design-related technical services is difficult to be measured, and only a handful of papers discussed the quality during the design stage. Although design cost is relatively far less than construction cost for a project, the decisions made in the design phase have a significant impact on the final products of the project, especially for large public construction projects. Therefore, this research focuses on reviewing and then establishing a performance evaluation framework for the consulting firms that execute detailed design and provide technical services for the Taipei Rapid Transit Systems (TRTS). By interviewing experts, this study first established a set of indicators to evaluate these firms' performance. Then, those indicators were incorporated into the four aspects of balanced scorecard (BSC) to establish the architecture of the evaluation mechanism. The weight of each indicator was calculated by analytic hierarchy process (AHP) from a survey conducted among experts. The results showed that the top-three indicators were quantity take-off, functions conformity, and budgeting. The framework of performance evaluation established by this study can be applied to measure service performance during the design stage. It not only facilitates the monitoring of consulting firms, but also helps to reduce unnecessary change orders and disputes during the construction stage.

  • This research examines the relationship between the characteristics of Government S&T Research Institutes (GRI) and their institutional performance evaluation system. First, based on Kaplan & Norton (1992) Balanced Scorecard Model, six perspectives suitable to Korean GRI are derived. Second, personnel who works on evaluation job classified current performance measures into the six perspectives. Analyzing comparative weights of individual perspectives, the characteristics of performance evaluation systems among institutes are derived and compared with their missions. The results are as follows: First, GRI evaluation systems put most weight on the customer perspective and least weight on the financial perspective. This result complies with Korean GRI's missions and strategies as well as findings of foreign cases. Second, Basic-technology GRI group relatively more priotizes long-term customer perspective, while Applied-technology GRI Group relatively more priotizes short-term customer perspective. Public-technology GRI Group is located in the middle in terms of priority of customer perspectives. Third, for three yews (2000-2002), performance measure weights of Basic-technology Group are changed much less than those of the other two groups. Further research are needed for reasons of drastic changes for Applied-technology and Public-technology groups and some abnormally high and low measure weights.

  • This paper analyses an impact of wage scheme and transparency of performance evaluation on the productivity. The main findings in this paper are as follows: First, the effect of wage scheme based on seniority system on the productivity is worse off than the performance pay. Second, there is a positive relationship between an incentive and the productivity, but, in the case of firms which individually informs the results of performance evaluation to their workers, it shows the hump-shaped relationship. Third, though the wage scheme is based on the performance, if the evaluation system is not transparent, the impact of incentive on the productivity is disappeared. Consequently, this paper implies that the appropriate incentive and the transparent performance evaluation system are required so as to improve the productivity.
