  • New product concept evaluation is one of the most important activities among many possible evaluation activities involved in the whole new product process. This paper aims at exploring the applicability of the Analytic Hierarchy Process(AHP) to this new product concept evaluation. To this aim, an AHP based concept evaluation model was formulated and explained using an illustrative example. A number of issues were also raised and discussed concerning the applicability of AHP to out problem. Finally, some further research areas were identified.

  • This study has improved the existed physical disturbance evaluation assessment technique in a river and analysed its applicability. The improvements are the quantitative evaluation items instead of qualitative one by providing the background and their evaluation equations, corresponding detailed itemization of evaluation score, and the direct input of hydraulic characteristics and geometrical changes by numerical simulation. In order to confirm the applicability of improved disturbance evaluation technique, the comparison and analysis between the evaluation results of existed and improved techniques have been carried out by applying to the 6 cases of natural, urban, and mountainous streams. Direct input of numerical simulation results of HEC-RAS enables the evaluation simple for 8 evaluation items excluding the items of habitat environment and bottom substrate. The improved disturbance evaluation technique, which evaluates the degree of disturbance sensitively by the quantitative and detailed itemized evaluations, has been confirmed the appropriate applicability by applying to river systems.

  • Simulation programs have been developed and used as an attempt to improve the accuracy of Non-Destructive Evaluation(NDE) techniques. The applicability of these programs is very limited, however, because it is difficult to describe the delicacy of the propagation of stress waves. To investigate the applicability of the finite element analysis for stress wave-based NDE techniques numerical simulation for Impact-Echo method and SASW method is performed. The numerical studies are performed to determine the essential parameters such as contact time of impact load, mesh size and time step size. These studies show that the choice of parameter is very important for improving the accuracy and confidence of the numerical procedure and, thereby, the applicability of the numerical analysis for stress wave-based NDE techniques

  • Along with the increasing demand for automatic and mechanical tunnel excavation methods in Korea, the Tunnel Boring Machine (TBM) method of tunnel excavation has become increasingly popular. However, in spite of this rising demand, few studies have been performed on the TBM method, in Korea. For this reason, this study focused on evaluation of the applicability of TBM performance prediction models based on field data in order to contribute to the basic and essential parts of TBM designation and the TBM method of tunnel excavation in Korea. These rock properties can be defined as the mechanical and physical factors of rock that have an influence on a disc cutter's ability to cut rock, and provide information for the evaluation of the applicability of field data. Based on outcomes from these tests, applicability of the prediction model was evaluated and the predicted performance of a TBM was compared with real field data obtained from four different TBM construction sites in Korea.

  • PURPOSES : Surface treatment material for pavement preventive maintenance should be inspected field applicability. This study(Part II) aimed to checkup coating characteristics and performance analysis using lab and field tests. The hydrophobic - low viscosity filling material for pavement preventive maintenance is presented in Part I, which is a series of companion study. METHODS : Relative comparison between general asphalt mixtures and surface treatment asphalt mixtures are analyzed and measured for the field application such as indirect tensile strength ratio(TSR), abrasion resistance, crack propagation resistance, temperature resistance, coating thickness, permeability resistance and skid resistance in terms of british pendulum number(BPN). RESULTS : It is found that TSR, crack propagation resistance and permeability resistance is increased as against uncoated asphalt specimen. Abrasion resistance and temperature resistance is secured from the initial coating thickness point of view, which is about 0.2~0.3mm. Skid resistance on the surface treatment pavement is satisfied with the BPN criteria of national highway because of exposed aggregate and crack sill induced pavement deterioration and damage cracks. CONCLUSIONS : The hydrophobic - low viscosity surface treatment material for pavement preventive maintenance is validated on field applicability evaluation based on quantitative analysis of coating thickness and performance analysis using lab and field tests.

  • As the interest in internet business increases, effective web site evaluation is in order. While web site evaluation is supposed to be based on feasible applicability and trust-worthy criteria. many researches on web site evaluation fails to rover the various business models and consider corporate-activity-related features. Besides, dealing with the limited aspects such as design and cognitive science is something to be desired on the previous researches. Therefore, This paper presents internet web site evaluation framework not only based on existing researches and analysis but also reflecting corporate strategies. The framework includes web sites contents, design, operation and management-related factors, and it is applied to companies to validate its applicability.

  • The purpose of this study is to develop evaluation indicators for academic libraries in Korea. The evaluation model developed in this research consists of three elements:(1) Confirmation of evaluation methods, procedures and criteria,(2) Development of qualitative and quantitative evaluation indicators, and(3) Assessment of the applicability and feasibility of those indicators. Evaluation indicators were developed to measure a basic state, a common use of library resources, specialized services, and user satisfaction for academic libraries. To test the feasibility and applicability of those evaluation indicators, a pilot assessment of academic libraries was conducted in 2010.
