  • 전문가 내지 구성원의 주관적인 의견에 의존하는 방법의 하나인 델파이법(Delphi Method)은 관련자료가 불충분한 중.장기 예측, 전략결정 등에 이용되고 있다. 이 방법을 더욱 발전시킨 퍼지 델파이법(Fuzzy Delphi Method)은 델파이법에 퍼지숫자(fuzzy number)의 개념을 도입하여 정확한 예측을 하고자 하는 것이다. 또한 이러한 예측치가 삼각 퍼지 숫자(Triangular Fuzzy Number)로 주어져 불확실성에 대한 예측과 의견종합을 쉽게 하며, 전문가에 의해 추정된 삼각 퍼지 숫자의 입력을 토애 그 추정치들의 비유사도(Dissemblance Index)와 퍼지거리(fuzzy distance)를 계산하고 간단한 그래프를 다시 전문가에게 피드백(feedback)할 수 있도록 나타내어지는 과정을 code화하여 전문가들로 하여금 다양한 정보를 통하여 좀 더 정확한 추정치를 예측하고자 한다.

  • This study was to investigate categories of valuation and make the standard on developing valuation of natural dyes by Delphi method. The three-round Delphi tests were performed with 36 professional in the academic, the industrial, and the art field.'Dyeability property' meant levelling, adsorption, color diversity with mordant, color stability, 'marketability', possibility of mass production, economical efficiency, functionality, demand and supply of natural dyes, 'color', yield, beautiful color, value of color and 'color fastness', washing, perspiration and light fastness. Indigo, persimmon, cochineal, safflower and onion in dyeability property were evaluated highly, functional natural dyes in marketability, red and purple color ones except indigo in color and ones containing tannin in color fastness.

  • The purpose of this study was to identify the focus of key issues - the view, the trouble, supplementary measures and future divection research, and commercialization${\cdot}$ popularization on natural dyeing. Delphi tests were performed with 36 professional in the academic, the industrial, and the art world. Questionnaire of 1round composed of open-ended question related the view, the trouble, supplementary measures and future divection research and commercialization${\cdot}$popularization. And a 5 point Likert Scale was used to evaluate them in 2 and 3 round. Results of this study and the order of importance in the focus of key issues are as following: The trouble are immoral business ability, using of excessive mordant and lack of standardization. Supplementary measures and future divection research are dyer education, choosing stuff on natural dyeing and consumer education${\cdot}$publicity. And commercialization${\cdot}$popularization are the development of brand, the production of specific goods by regional groups, high-grade articles and the certification system in quality.

  • The purpose of this study was to value the present condition of natlwal dyeing, to forecast needs in natural dyeing world and to off the preliminary data on future direction of research and enhancement plan. The three-round Delphi tests were performed with 36 professional in the academic, the industrial, and the art world. The result of the study is as follows: Factor analysis showed the troubles were classified into 4 categories; 'dyeing', 'basis', 'industry' and 'consumer and environment'. Supplementary measures and future direction research 3categories; 'development', 'education' and 'mass production' And commercialization. popularization 2 categories; 'commercialization' and 'popularization'. 'Dyeing' is correlated with 'mass production', 'basis' with 'education' and 'education' with 'commercialization' and 'popularization'. The engaged period in natural dyeing world is longer, professionals were more concerned about 'consumer and environment' The most influential element of the present question in the view is 'education'.

  • The purpose of this study is to use K-MOOC, which has limitations in utilization because it is centered on theory delivery, to derive tasks to activate the teaching methods of instructors, and to implement the derived tasks using the metaverse platform. to develop a prototype. According to the purpose of the study, the study was conducted as follows. First, from October 4 to November 15, 2022, a Delphi survey was conducted on 21 experts with experience of consulting, research, class development, and operation related to the K-MOOC project. Second, in order to realize the tasks in the teaching method field derived from the Delphi survey, matching with the teaching method class model elements to result of Delphi survey was applied was carried out. Finally, based on the results of expert Delphi and the elements of the class model applicable to the metaverse platform, a teaching method was developed. Through the process of the study, a total of 16 detailed items were derived for the teaching method-related tasks for the activation of K-MOOC: support strategic tasks, teaching method competency, aspect of class design, evaluation and sharing of learning outcomes. By applying the metaverse, the teaching model elements for K-MOOC revitalization were derived from four categories: self-directed repetition, individualized problem solving, practice opportunity expansion, and immediate feedback, and matched with the first 16 detailed items. A four-step teaching model was completed: course attendance (step 1), mission analysis by individual level (step 2), sharing of mission solutions (step 3), and mission evaluation and feedback (step 4). Through the results of this study, the possibility of using the metaverse as a teaching practice platform was confirmed even in terms of the introduction and development of specialized techniques.

  • In the current era of Corona, the positive potential of board games is emerging as the 'untact' is accelerating. This situation can be seen as an opportunity to have a positive impact on the development of the board game industry depending on how to develop board games in a more interesting, high-quality and educational way than before. To this end, this study intends to present a methodology for deriving the relative importance of important factors in board game development among the preceding studies and methodologies for more advanced board game development by board game developers and experts. This study is to derive the relative importance of important factors in board game development. To this end, important factors in board game development for board game developers and experts were derived through the Delphi method, and the Delphi method in the ranking format was used to rank the relative importance of the derived factors. This study focused on the development model of playing cards among board games. Priority analysis result, development and planning composition, prior research analysis, draft production, production, validation, application, and review in order of importance were derived(were derived in the order of importance). The results of this study are expected to provide practical guidelines for companies to prioritize and utilize development according to their importance when developing board games.

  • In this study, I worked on necessary contents for Information Literacy of Korean universities by Delphi Method. The survey resulted in 100 necessary contents in five categories and each category presents average points and ranks of importance. Contents of high rank in each category should be valued highly when educational programs are to be designed. One remarkable difference in comparison with ACRL standards is that there are a lot of contents involved with basic understanding about Scientific Information System and Information Technology and knowledge application in this study, and another is that there is a lack of contents which require analytic judgements. The significance of this study lies in presenting directions and discussion points in designing of Information Literacy of Korean universities.

  • This paper describes a new quantitative process for evaluating the roughness of discontinuity, which is suggested as a qualitative criteria in RMR or Q-system. For this purpose, the Delphi method which is one of the surveying methods was introduced. The selected panels were asked to evaluate the roughness of discontinuities on the Web which was hosted by authors in advance. A total of 3 surveys were performed using JRCs suggested by Barton and Choubey as well as Ai generated by the Monte Carlo simulations. After each survey, the results were provided to all panels for comparing their decisions to others. As surveys proceeded, better consensus and convergence were achieved. With a good agreement of panels on roughness classification, the quantitative criteria for roughness of discontinuity in RMR and Q-system was established in this study.
