The ITS performance evaluation has been performed in the evaluation of traffic data collection equipment. However, evaluation of the data collection equipment alone cannot guarantee the reliability of the traffic information. So, ITS service evaluation has to be implemented institutionally. In this study, an evaluation method has been prepared to evaluate the accuracy of travel time information in road sections. In addition, a piece of portable reference equipment was developed to collect travel time data on the road. Field tests were performed on two national road sections managed by the Seoul Construction and Management Administration (SCMA) to prepare an evaluation method considering field conditions and evaluate the reference equipment's performance. Based on the test results, the improvement of the reference equipment to collect more samples and the adjustment of collection points were discussed.

Alkali-silica reaction (ASR) in concrete can induce degradation in its mechanical properties, leading to compromised serviceability and even loss in load capacity of concrete structures. Compared to other properties, ASR often affects the modulus of elasticity more significantly. Several empirical models have thus been established to estimate elastic modulus reduction based on the ASR expansion only for condition assessment and capacity evaluation of the distressed structures. However, it has been observed from experimental studies in the literature that for any given level of ASR expansion, there are significant variations on the measured modulus of elasticity. In fact, many other factors, such as cement content, reactive aggregate type, exposure condition, additional alkali and concrete strength, have been commonly known in contribution to changes of concrete elastic modulus due to ASR. In this study, an artificial intelligent model using artificial neural network (ANN) is proposed for the first time to provide an innovative approach for evaluation of the elastic modulus of ASR-affected concrete, which is able to take into account contribution of several influence factors. By intelligently fusing multiple information, the proposed ANN model can provide an accurate estimation of the modulus of elasticity, which shows a significant improvement from empirical based models used in current practice. The results also indicate that expansion due to ASR is not the only factor contributing to the stiffness change, and various factors have to be included during the evaluation.

It is highly required to evaluate the economic value of technology in many decision making of the technology management area, for example, technology acquisition, transfer, and investments. Also evaluating the performance of R&D objectively is very important subject in the public side. So, developing the objective technology evaluation system has much usefulness in practice. In many studies, the patent information has been suggested to the valid measurement for evaluation of technology. The purpose of this study is to explore the validity of patent information as a measurement of technology evaluation.

In this study, the product design technology to facilitate the assembly automation is developed. First, checkistis are developed to analyse weakpoints which make assembly automation difficult. The weakpoints of assembly automation can be redesigned by using design rules for assemblability which are systematized in this research. In addition, the assemblability of product can be evaluated qualitatively with the new developed assembly evaluation method. This evaluation method is performed in the respect of the component parts, the assembly method and the assembly motion.

The research question of this work comes from that there have been disputes for the governance and roles of the Rural Development Agency (RDA), despite of rather excellence performances of Agricultural R&D program supported by RDA. For this reason, I meta-evaluated the internal evaluation system of Agricultural R&D program in RDA, in terms of the four meta-evaluation components such as evaluation paradigm, evaluation resources, evaluation execution and evaluation utilization. The result shows that the most serious problem is rather lower level of evaluation. Object, one of the evaluation paradigms in the R&D evaluation system of the RDA. So, this work suggested the policy alternatives which may lead the R&D evaluation system of the RDA to be developed for the performance-oriented R&D management system.

In this paper, we explained the relation between evaluating display device and emotional image quality evaluation in human perceptual view. It is also suggested two emotional image quality evaluation method of display reflecting human visual function. One is the color space of CIECAM02 and the other is capturing moving image. It is necessary to standardize the evaluation methods of image quality based on emotional evaluation.

This study analyzed the trends of patents for unmanned technology used in agriculture. The target countries for this survey of patent data were Korea, the USA and Japan as well as the countries in Europe. The indices used in this study to analyze the patents were the CPP (Cites Per Patent), PII (Patent Impact Index), and PFS (Patent Family Size). The total effective patents for unmanned technology used in agriculture were 1,080 cases. The number of patents in the USA, Japan, Europe, and Korea were 541, 326, 128 and 85 cases, respectively. Among the total effective patents, the evaluation scores for selected important patents were calculated by applying commonly used weights to each index, and the top 10 patents were selected as important patents. The results showed that all the top ten patents are owned by the United States and that the United States is an advanced country in the field of unmanned technology used in agriculture. The evaluation score of the important patents using the existing method was biased toward the PII index among the three patent evaluation standards, and the effects of the number of claims and the PFS were relatively small. Therefore, a reliable patent analysis in the field of unmanned technology used in agriculture needs to reflect the overall evaluation factors taking into consideration the scope of the evaluation factors.

This study suggests the effectiveness of an "extended" power system evaluation methodology based on LCA and energy input-output analysis techniques. This "extended" evaluation methodology is designed to incorporate total energy system costs through fuel cycle and external costs, including CO$_2$abatement cost. As an empirical test, we applied the methodology to orimulsion-fired power generation technology and found that orimulsion could be considered as in attractive base-load power generation fuel in terms of economic and environmental aspects, compared to conventional coal-fired power plant.
