  • In this study, a seismic performance evaluation of unreinforced masonry buildings was conducted based on a revised draft of the outline of the seismic performance evaluation of existing buildings. The procedure of the performance evaluation is composed of three-steps, which are a preliminary evaluation, a first-level detailed evaluation, and a second-level detailed evaluation, where evaluation is conservatively conducted in the beginning and then more detailed evaluations are gradually conducted. For the study, ten two-story unreinforced masonry buildings were selected and evaluated using the three-step evaluation. The result showed that the performance levels between the preliminary and the first-level detailed evaluations were reversed, which is different from the intent of the procedure. Therefore, in the near future, the problems in each evaluation step that are presented in the results of this study need to be refined.

  • Purpose - The purpose of this study was to examine the internal relevance between digital transformation, manipulation of asset evaluation and corporate M&A performance and further explores the impact path of manipulation of asset valuation on corporate M&A performance. Design/methodology/approach - This study based on the financial data of A-share listed companies in Shanghai and Shenzhen Stock Exchanges from 2013 to 2021. Findings - First, manipulation of asset evaluation is negatively correlated with M&A performance. Second, Digital transformation significantly weakens the negative correlation between manipulation of asset evaluation and corporate M&A performance. Third, The effectiveness of internal control plays a partially intermediary role in the process of manipulation of asset evaluation affecting M&A performance. Research implications or Originality - Enriching the existing literature on the subject, the study can also provide useful reference for improving the performance of corporate mergers and acquisitions, regulating asset valuation, promoting the digital transformation of enterprises and improving internal control mechanisms, with both theoretical and practical implications.

  • This study aims to propose the ways to improve the research performance evaluation to support the establishment of a sound research culture. For the study, we analyzed the cases of domestic and foreign research performance evaluation, and a survey and an interview were conducted for faculty and research performance evaluation officials, respectively. In the study, the direction of establishing the principle of research performance evaluation, the method of categorizing the type of research performance, the method and procedure of research performance evaluation, and necessary documents were proposed. First, eight principles were suggested to be considered in evaluating research achievements to ensure the validity, reliability, and transparency of the evaluation while supplementing the limitations of quantitative evaluation. Second, the main types of research achievements were categorized into journal articles, books, and presentations at academic conferences. Third, as a research achievement evaluation method, a hybrid evaluation using quantitative and qualitative and multiple measurement indicators was proposed. Fourth, a total of 11 steps (required 7 steps) were presented as a procedure for research achievement evaluation. Fifth, publications, evaluation documents, and committee chair's reports were proposed as major documents for research achievement evaluation. The research achievement evaluation improvement plan presented in this study should be flexibly applied in consideration of the characteristics of the academic and research fields and universities.

  • The safety related heat exchangers have been evaluated for their performance during the operation of the nuclear power plant. The evaluation program for the safety related heat exchanger was developed in 2010 and used by KHNP based on EPRI TR-10739 algorithms. The spend fuel pool heat exchanger is one of the safety related heat exchanger in the nuclear power plant and also evaluated for their performance. Recently the performance evaluation for the spend fuel pool heat exchanger was not available because of the decreased heat in the spend fuel pool due to the long term overhaul. This paper analyzes the main cause of evaluation failure in the evaluation process and suggests the criteria for the heat exchanger performance evaluation during the long term overhaul.

  • Based on the characteristics of 'Korean electric power industry R&D programs', this study proposes a new performance evaluation framework where electric power industry related R&D projects are scrutinized. The abovementioned R&D programs have their own goals and especially they emphasize the effectiveness as well as the efficiency of each subordinate R&D project. Hence, in this framework, a performance evaluation procedure is established and then a mathematical model is developed according to the procedure. The model calculates performance evaluation indices for a set of R&D projects integrating the effectiveness with the efficiency of each R&D project. In a case study with an empirical dataset, statistical significance is tested on the integrated performance evaluation indices of R&D projects regarding organizational types and program categories considered.

  • For the evaluation of the mobile robot performance in complex environments, the experimental approach in an actual physical environment has been commonly taken. In the physical experimental approach, however, it is quite difficult to define the proper environment for the evaluation due to the lack of commonly agreed characteristics of the test environment. Particularly the number of combinations of types and physical parameters of the obstacles that the mobile robot is expected to deal with is practically unlimited. In an effort to simplify and improve the effectiveness of the evaluation process, we propose an evaluation method using decomposed environmental elements, where we evaluated the performance of the robot for a small group of simple and decomposed obstacle components, for examples projection and slope, instead of a large group of complicated random obstacles. The paper describes a set of simple obstacle models and performance parameters that we have chosen for the effective evaluation process. As an alternative to the physical experimental evaluation approach, in this paper, we used a virtual evaluation environment where the robot and the physical test environment has been modeled using a commercial multi-body dynamics analysis packaged called RecurDyn.

  • Evaluation method of seismic performance has mainly used elastic spectrum analysis. This method has simplicity of analysis but deficiency of accuracy. And evaluation method of seismic performance using inelastic dynamic analysis reflects accurately inelasticity of material but hardly reflects site effects. This study suggested evaluation scheme of seismic performance for bridge structure using capacity spectrum method applied inelastic static analysis and standard design response spectrum of Korea Standard Specification for Highway Bridge. Two results, capacity spectrum method and inelastic dynamic analysis method, are very similar. As a result, this study appropriately supply both simplicity of analysis and accuracy of result.

  • 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.
