  • The condensation performance evaluation is required for improved living environment of apartment housings. In the current condensation performance evaluation process, high demand of manual works and repetitive process cause unexpected risks due to uncertainty and inefficiency by applying 2D CAD drawings in simulation tool. Furthermore, the evaluation requires taking in action responding to the expanding use of BIM. In this study, the analysis of current evaluation process and required functions for the process improvement based on BIM modeling were deducted from interviews with experts. It is expected that the results of this study can be employed to develop of process automation module for condensation simulation evaluation.

  • The performance database of small-sized centrifugal compressors is needed for the design of high performance machines and also for the verification of design tools and analysis software. An impeller is designed, manufactured and tested. The effects of several parameters on the evaluation of performance are investigated and the performance test of parallel diffuser is also carried out. The proper estimation of static pressure, total temperature and blockage at the impeller exit is important for performance evaluation. 4 method in cooperation with 3-D calculation is suggested. The measured performances are in a good agreement with the predicted results. However, there are some discrepancies in efficiency.

  • For an advanced intelligent service, the need of HRI technology has recently been increasing and the technology has been also improved. However, HRI components have been evaluated under stable and controlled laboratory environments and there are no evaluation results of performance in real environments. Therefore, robot service providers and users have not been getting sufficient information on the level of current HRI technology. In this paper, we provide the evaluation results of the performance of the HRI components on the robot platforms providing actual services in pilot service sites. For the evaluation, we select face detection component, speaker gender classification component and sound localization component as representative HRI components closing to the commercialization. The goal of this paper is to provide valuable information and reference performance on appling the HRI components to real robot environments.

  • For performance evaluation of modified wide sleepers(MF-140 PSC sleepers), design moment for urban transit was calculated and then performance evaluation criteria were set up according to EN 13230-2. Next, static bend tests, dynamic tests at rail seat section of sleeper were carried out and static bend tests at center section of sleeper were fulfilled. The test results for modified wide sleepers were in excess of performance evaluation criteria and structural safety of sleepers was able to guaranteed from the results. As modifying depth of wide sleepers, construction convenience in underground will be expected to be improved and construction costs will be expected to be decreased.

  • Most studies in the past in testing and benchmarking on Intrusion Detection System (IDS) were conducted as comparisons, rather than evaluation, on different IDSs. This paper presents the evaluation of the performance of one of the open source IDS, snort, in an inexpensive high availability system configuration. Redundancy and fault tolerance technology are used in deploying such IDS, because of the possible attacks that can make snort exhaust resources, degrade in performance and even crash. Several test data are used in such environment and yielded different results. CPU speed, Disk usage, memory utilization and other resources of the IDS host are also monitored. Test results with the proposed system configuration environment shows much better system availability and reliability, especially on security systems.

  • This study focuses the relationships of job performance abilities with learner satisfaction and learning performance for NCS-based courses in colleges from instructors' perspectives. The results of this study show that the satisfaction of learners for NCS-based courses is statistically higher when learners are evaluated 3 times or more rather than twice or less. And also it reports that when 3 or more different evaluation methods are applied per evaluation of job performance ability, learner satisfaction is statistically higher. On the other hand, the performance of learners is turned out to be better with both evaluations of 3 times or more, and 3 or more different evaluation methods per job performance ability. However those results are not statistically meaningful. It concludes that from a view of process-based formative evaluation, evaluating job performance ability itself should be considered as an activity for improving teaching and learning in higher vocational education of colleges.

  • In this paper, we introduce an integrated performance evaluation model defined by the three indices (evaluation index for each evaluation stage, performance viewpoint, and performance type) and analyze the utilization and satisfaction of the seven public u-IT services implemented from 2008 to 2009 using the proposed model. From the performance results of the public u-IT services, it was found out that most of the research goals initially set by the public u-IT service support projects were satisfied. Furthermore, we suggest improvement directions and promotion strategies of future projects.
