  • To constuct the stochastic model for performance evaluation of Multi-AGV, two aspects must be considered. The first is stochastic situation for moving jobs. The second is the dispatching rule of AGV. In this paper, the stochastic model for performance evaluation of Multi-AGV is developed. The case of stochastic model with two AGV is developed. But it difficult to solve in the case of stochastic model with more than three AGV because the model have three-ordered equations. The evaluation factor of the model is utilization and empty travel time of AGV. Using these factors, one can easily evaluate a wide range of handling and layout alternatives from given flow data. Hence, the model would be most effective when used in the early stage of designing to narrow down the number of alternative prior to simuation.

  • Objectives: This study was to compare the self-evaluated outcomes of communication competency in dental hygiene process of care in the students of a dental hygiene department with the teaching evaluation, and to confirm the difference of communication competency by the evaluator. Methods: This study attempted to confirm the value and usefulness of self-evaluation and teaching evaluation on the communication competency. The subjects of this study were 43 junior students who took a course of dental medical communication at the dental hygiene department of a university located in 'A' city, and the self-evaluation and teaching evaluation were conducted using the evaluation paper which was modified from the communication evaluation tool in the previous studies. The collected data were subjected to the correspondence sample t-test to compare the difference between the communication competency self-evaluation before and after the education, and after communication education, while an independent sample T-test was conducted to compare the differences between the evaluators. Results: The student's self-evaluations before and after the education showed the statistically significant difference, moreover, the post-education competency scores were improved mostly in all the items more than the pre-education competency scores. The score of self-evaluation was higher than that of the teaching evaluation in all items except one question in the case of history-information collection stage. Conclusions: It is confirmed that there is an effect to allow the students to improve their communication competency in the dental health communication education in the dental hygiene department. To evaluate the student's communication competency, the mutual complement of self-evaluation and teaching evaluation should be confirmed in parallel each other.

  • In the past decade, considerable effort has been devoted unsuccessfully to the development of information technology (IT) evaluation frameworks in the information systems area. Based on the literature review in this area and the decision analysis field, two competing evaluation frameworks are developed in this study: the direct evaluation framework and the indirect evaluation framework. A case study on Firm K shows that the latter is more practically efficient and theoretically appropriate but requires the adequate training for practitioners in order not to get confused the weight of an evaluation variable with the product of this weight and the score of the variable. Another finding is that Weill's conversion effectiveness is neither possible nor necessary to measure in the process of evaluating an IT although it is in theory an important concept.

  • The purpose of this study is to explore how people's evaluation and preference on color palettes differ based on their cultural background. This study used the same color palettes developed by Youngsoon Park and Denise Guerin(1992). Fourteen representative adjectives are used to analyze the meaning evaluation and preference on the six color palletes. 425 undergraduate students are se-lected from Korea, Japan, U.S. and England and ques-tionnaire was used as survey instrument. The results show that there are significant differences among the four countries in the meaning evaluation and preferences on the color palettes and the characteristics of color palettes influence the differences among the countries. The differences among the countries decrease in case of color palettes composed of warm color with low or medium value difference and chroma difference, while the differences increase in case of color palette characterized by strong color contrast with high or medi-um value difference and chroma difference. The result of color meaning evaluation can be catego-rized into Western and Eastern culture. Korea and U.S., and Japan and U.S. showed significant differences in the most words and Korea and Japan showed similarities in the most words. Therefore it can be concluded that cul-tural backgrounds related to race, region and history in-fluence the color meaning evaluation and preference. Fur-ther study should explore the relationship between color and culture using more various color instruments such as color palettes in order to categorize the various aspects of culture.

  • The capital cost of the company is one that must be paid to the money owner as the price by using the money. The capital cost according to the source of money supply can be estimated by the expected profit rate undertaken by the use of the capital. But in the area of pre-existent economic evaluation, the evaluation of the company investment has been treated by the profit rate of the capital after considering the repayment conditions of the other's money or the interest. Thus in this study, in case the company makes an investment on various kinds of the capital at the same time, not make use of the capital as a one source, the economic evaluation of an investment should be handled by taking the weighted average cost of capital into consideration in proportion to the constitution of the capital cost by the sources of money supply, Especially, as the cost of the private money is very much connected with the profit rate through the stock market, the Capital Asset Pricing Model (CAPM) will be applied. This kind of economic evaluation method can be said to have much to do with the Economic Value Added : EVA) as well as to be highly thought as a standard to estimate the company' value recently To certify the usefulness of this approach, the case study of the output of the capital cost will be made for the purse of the economic evaluation of the alternative investment by using the financial statements of a motor company H.
