Recently, the development of technology has been rapidly proceeding with information technology in various fields. Due to their abstract properties, proper evaluation of intangible assets is very difficult compared to evaluation of tangible assets. Intangible assets are knowledge, technology, and design etc. In general there are two approaches to evaluate the intangible assets such as qualitative and quantitative approach. The qualitative approach contains scoring approach, profile approach, checklist approach, and quantitative approach. Quantitative approach contains cost approach, market approach, income approach, and real-option approach. As an initial step for evaluation of safe work environments, this study compares and analyzes evaluation methods of intangible assets.

Accurate actuator tracking is critical to achieve reliable real-time hybrid simulation results for earthquake engineering research. The frequency-domain evaluation approach provides an innovative way for more quantitative post-simulation evaluation of actuator tracking errors compared with existing time domain based techniques. Utilizing the Fast Fourier Transform the approach analyzes the actuator error in terms of amplitude and phrase errors. Existing application of the approach requires using the complete length of the experimental data. To improve the computational efficiency, two techniques including data decimation and frequency decimation are analyzed to reduce the amount of data involved in the frequency-domain evaluation. The presented study aims to enhance the computational efficiency of the approach in order to utilize it for future on-line actuator tracking evaluation. Both computational simulation and laboratory experimental results are analyzed and recommendations on the two decimation factors are provided based on the findings from this study.

The hot spot stress approach is usually adopted in the fatigue design and analysis of tubular welded joints. To apply the hot spot stress approach for fatigue evaluation of long span suspension bridges, the FEM is used to determine the hot spot stress of critical fatigue location. Using the local finite element models of the Tsing Ma Bridge, typical joints are developed and the stress concentration factors are determined. As a case for study, the calculated stress concentration factor is combined with the nominal representative stress block cycle to obtain the representative hot spot stress range cycle block under traffic loading from online health monitoring system. A comparison is made between the nominal stress approach and the hot spot stress approach for fatigue life evaluation of the Tsing Ma Bridge. The comparison result shows that the nominal stress approach cannot consider the most critical stress of the fatigue damage location and the hot spot stress approach is more appropriate for fatigue evaluation.

This study explores the differences in product evaluation and approach behaviors as well as the effects of product evaluation on approach behaviors of utilitarian and hedonic products in on-line and off-line settings. A total of 332 subjects participated in the experiments to assess product evaluation and approach behaviors for utilitarian and hedonic clothing products in on-line and off-line settings. The results show that even though the same stimulus was presented, consumers' product evaluation of utilitarian clothing (i.e., t-shirts) was higher in the off-line setting than in the on-line setting while the approach behavior of hedonic clothing was better in the on-line setting than in the off-line setting. In addition, color was a crucial factor generating positive approach behaviors for utilitarian clothing while style and quality were core factors influencing the approach behaviors of hedonic products in an on-line setting. There was no consistency in the results of the important factors affecting approach behaviors of utilitarian and hedonic clothing in an off-line setting. The conclusion suggests implications for marketing based upon the results of this study.

This paper deals with the evaluation problem of complex systems by introducing a fuzzy approach. The authors are functionally supposing a hierarchical structure model of a complex system and give light on the following problems. First for the purpose of clarifying the characteristics of measures the property and differences between two method such as linear and fuzzy viewpoint are discussed through two level-down evaluation process. Second the integrated evaluation process which keeps reversibility between hierarchical levels is discussed and obtained some necessary conditions for reversibility of fuzzy evaluation. From these results it is expected that the fuzzy approach overcomes partly the limitation of reductionism at the hierarchical evaluation of complex systems.

Phenomenological approach suggests a new dimension in landscape evaluation, which is a contrast to the existing scientific evaluation methods. The characteristics of the phenomenological approach is qualitative, holistic, open, and experiential, whereas that of the scientific approach is quantitative, reductive, closed, and experimental. In phenomenological approach, the average response of a group is not considered as meaningful in landscape evaluation. Instead, the individual response, experience, and feeling are considered as important. In phenomenological approach, people try to see the real world as it is, while scientists tend to simplify the real world in order to handle the complex Phenomena easily. Due to its holistic and qualitative nature, the phenomenological approach has limitations to be a practical landscape evaluation technique. However, recent research demonstrate the possibility of practical phenomenological landscape evaluation technique which is able to satisfy the criteria scientific methods should meet.

This paper presents a new approach of risk evaluation method for the reinforced slopes. In order to perform this study, the existing stability and risk evaluation methods are reviewed and analysed in terms of rainfall, ground condition, and drain conditions. According to the characteristic of the reinforced slopes improved by internal and external reinforcement, the nineteen influence factors are determined in order to develop new risk analysis model based on 'Interaction matrix' approach suggested by Hudson (1991). Using new approach of slope risk analysis model, the weighting values for interaction factors are analysed and determined. Based on new slope risk evaluation approach, the slope risk index, namely SRI (Slope Risk Index) is developed in this study to apply the evaluation of the reinforced slopes. In order to verify the SRI, a total of 15 cases are studied and analysed. The analysed results are compared and evaluated. According to the results, it is deduced that new slope risk evaluation method (SRI approach) IS very useful and practically a reliable method to evaluate the existing slopes.

Recently, software quality evaluation based on ISO/IEC 9126 and ISO/IEC 14598 has been widely accepted in various areas. However, these standards for software quality do not provide practical guidelines to apply the quality model and the evaluation process of software product=5. And the qualify management in most software projects has been conducted by managing defects without applying the standards for software qualify. Thus, we present a quantitative quality evaluation approach of artifacts in the Component Based Development (CBD). Particularly, our evaluation approach allows most of the standard evaluation process and adopts a quantitative quality model which uses the weights of quality characteristics obtained through carefully selected questionnaires for stakeholder and Analytic Hierarchical Process(AHP). Moreover, we have also examined the proposed evaluation approach with applying the checklists for the artifacts of the CBD to a small-scale software project. As a result, we believe that the proposed approach will be helpful for acquiring the high quality software.
