  • This study aims to propose a determinant model to select a method on calculating weight of each indicator for environmental evaluation. According to analyzing and comparing with three types of methods for calculating weights which are usually used to evaluate environment with indicators, the weights which were obtained by each type were all different from each other. This means that a differential weighting method must be applied to each of environmental evaluation studies. Therefore, a determinant model is required to determine weight-calculating methods. Three types of weighting methods, such as weighting by importance degree, weighting by eigen-value and weighting by analytic hierarchy process, were compared. Under the necessity, a determinant model was drawn for selecting a compatible method to calculate weights of indicators in environmental evaluation.

  • The design functionality put forward by mapping the interactiveness of information. The presentation of such information with the user interface model indicates that the guidelines, concepts, and workflows form the deliverables and milestones for achieving a visualized design, therefore forming the right trend is significant to ensure compliance in terms of changing consideration and applying evaluation in the early stages. It is evidenced that prototype design is guided by improvement specifications, includes modes, and variables that increase improvements. The study presents five user interface testing methods. The testing methods are heuristic evaluation, perspective-based user interface testing, cognitive walkthrough, pluralistic walkthrough, and formal usability inspection. It appears that the five testing methods can be combined and matched to produce reasonable results. At last, the study presents different mobile application designs for student projects besides the evaluation of mobile application designs to consider the user needs and usability.

  • The purpose of this study is to compare student evaluation methods in team based learning classes for dental hygiene students. The subjects of this study were the score of dental hygiene students who took the courses of 'oral health education practice'. The analysis methods were spearman correlation analysis, skewness, kurtosis and Mann-Whitney U test. As a result, there was a significant correlation between the self-evaluation and peer-evaluation. Self-evaluation showed lenience tendency rather than peer-evaluation and self-evaluation found the highest central tendency. The peer-evaluation result was more lenience and more central in the group where self-evaluation was performed.

  • To quantify the conservatism of existing ASME strain-based evaluation methods for seismic loading, this paper presents very low cycle fatigue test data of elbows under various cyclic loading conditions and comparison of evaluation results with experimental failure cycles. For strain-based evaluation methods, the method presented in ASME BPVC CC N-900 and Sec. VIII are used. Predicted failure cycles are compared with experimental failure cycle to quantify the conservatism of evaluation methods. All methods give very conservative failure cycles. The CC N-900 method is the most conservative and prediction results are only ~0.5% of experimental data. For Sec. VIII method, the use of the option using code tensile properties gives ~3% of experimental data, and the use of the material-specific reduction of area can reduce conservatism but still gives ~15% of experimental data.

  • The purpose of this research was to analyze how the evaluation method affects the subjective hand evaluation of fabrics and to suggest the efficient evaluation method. Three methods such as the sense of sight & touch, the sense of touch, and the sense of sight were respectively used when judges estimated the hand of fabrics using questionnaire. The result obtained by the method of touch was same as that by the method of sight & touch. The time required for the evaluation by these two methods was statistically same. Consequently, the method of touch has no attraction compared to that of touch & sight. In case of using the method of sight, 8 properties among 10 showed the same results as in the method of sight & touch. The properties of [moogupda/kabyupda] and [shinchuksung-e-itda/ shinchuksung-e-upda] evaluated with the sense of sight were different from the results obtained by the other methods. These properties seem to be difficult to evaluate only by seeing the fabric on the table. For the precise evaluation, it is necessary to show dynamic movement of the fabric. The time required for the evaluation by the sense of sight was shorter than that by the other two methods.

  • This study focuses on design of supplementary evaluation indicator system geared towards comprehensive rearrangement projects in seats of township and town offices. In the first phase, it tries to reveal major problems and issues related to evaluation of the existing small town promotion projects. In terms of analytical tools, this study depends on the Delphi and AHP techniques. In specific, after three rounds of the Delphi methods, it extracts a series of alternative evaluation indicators derived from the AHP methods. It covers 5 major evaluation criteria, under which 18 independent items are hierarchically interconnected. It expects that these alternative evaluation indicators would contribute to selecting appropriate small town promotion projects. Next, applying these evaluation indicators, we examine couples of comprehensive rearrangement projects in seats of township and town offices. From the comparative contexts, we believe that the proposed alternative evaluation criteria would improve the general satisfaction level of key stakeholders in deciding the priority order of the small town promotion projects.

  • In order to minimize a biased view of evaluators in usability test, a multiple evaluation method so called Multi-Centered Usability Evaluation Method(MCUEM) was suggested and structured in this study. To use MCUEM, the existing evaluation methods were re-categorized into 'developer and evaluator-centered', 'evaluator-centered', 'user-centered', 'evaluator and user-centered', and the 'developer, evaluator, and user-centered methods. Furthermore, in order to verify the relevance of MCUEM, the usability of mobile phone was tested in this study. In results, it was found that different evaluation methods generated greatly different results, that showed the risk of using a particular usability method due to different perspectives of evaluators. At the same time, it was found that MCUEM could greatly minimize such biases. Therefore, it was concluded that using MCUEM could help the usability engineer design a test protocol with a minimal risk of bias due to different perspective of evaluators.

  • Recently new materials, such as fiber reinforced polymer(FRP) and other composite materials are being applied in reinforcing plate or plate or prestressing cables of concrete structures. Although these new materials themselves show the excellent durability and high strength, the bond behaviour between concrete surface and FRP is not well recognized. Therefore, this paper propose a evaluation method for effective bond length between fiber reinforced polymer(FRP) and concrete. To develop the evaluation method, this paper presents a review of current evaluation methods for effective bond length. These methods are compared by single face test, expose merits and demerits. And based on them, new evaluation method was developed. Finally, the new method was compared with existing methods to verify a adequateness for evaluation of effective bond length.

  • This paper describes the methods for calibration and evaluation of the relative expanded uncertainty of a multi-axis force/moment sensor. In order to use the sensor in the industry, it should be calibrated and its relative expanded uncertainty should be also evaluated. At present, the confidence of the sensor is shown with only interference error. However, it is not accurate, because the calibrated multi-axis force/moment sensor has an interference error as well as a reproducibility error of the sensor, etc. In this paper, the methods fur calibration and for evaluation of the relative expanded uncertainty of a multi-axis force/moment sensor are newly proposed. Also, a six-axis force/moment sensor is calibrated with the proposed calibration method and the relative expanded uncertainty is evaluated using the proposed uncertainty evaluation method and the calibration results. It is thought that the methods fur calibration and evaluation of the uncertainty can be usually used for calibration and evaluation of the uncertainty of the multi-axis force/moment sensor.
