The purpose of this study is to provide basic data and guideline to STEM(Science, Technology, Engineering, Mathematics) educators who prepare engineering education in elementary and secondary school. For this, this study develops a composition model for engineering education program of elementary and secondary school. To do this, a literature research, experts interview and Delphi survey were conducted. Through the literature research, we extracted the components of model for engineering education program of elementary and secondary school and then made a first draft of the model. The draft was revised by experts while Delphi survey was used to validate the model based on Delphi panels' opinions. The panels for the Delphi survey consisted of 51 experts in the STEM education field. The survey was conducted three different times and importance survey was included in the third stage. The conclusions of this study were as follows: First, the model consist of definition, 4 directions, 4 characteristics, 3 educational goals according to school level, educational contents area and element, teaching and learning method and evaluation method. The educational contents area and element consist of 2 major areas, 7 areas and 18 elements. Second, all components of the developed model were valid in most of the statistics such as mean, standard deviation, the degree of consensus and convergence, and CVR(Content Validity Ratio). Third, importance for education contents area and element according to the school level are analyzed.

The purpose of this paper was to investigate mathematics gifted educational methods based on STEAM education by Delphi study. As a result by total 3 round Delphi method, the concept of STEAM education for mathematics gifted students was education of developing capacity of Holistic Growth that can communicate diverse people through self-monitoring study as they can find and solve problems with integrative thinking and creative thinking. Thus this elicited the consensual agreements of experts about mathematics gifted educational goals, methods, contents, and evaluations etc. As a follow-up research will be developed mathematics gifted educational model based on STEAM education.

In this study, we consider a mid-and-long term technological forecasting method based on simulation technique. We, first, gather information about a point of appearance time of new technologies which will be developed in the future and influence relationship among those technologies by Delphi survey. And then we propose a simulation-based heuristic approach searching for the key technology among new technologies which will be developed to attain a normative objective using the Delphi data. We also provide the range of occurrence time for individual technology and define key technologies in this study in contrast that a expert's estimate to occurrence time is only one point in traditional Delphi survey. The information for key technologies which are detected by this procedure gives priorities of R&D planning and aids the R&D planner or project manager in resource allocation.

The purpose of this paper was to investigate science gifted educational methods based on creativity and character by Delphi study. As a result by a total 3 round Delphi method, the concept of creativity and character education for science gifted students was to promote character development through the effectively interactive communications in the process of creative problem finding and solving. Thus this elicited the consensual agreements of experts about science gifted educational aims, methods, contents, and evaluations etc. As a follow-up research will be developed science gifted educational model based on creativity and character.

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 paper introduces the development and current prosperity of the branch discipline of visual anthropology and describes the status and current situation of modern visual anthropology and analyzes the rationality that the achievements of visual anthropology is viewed as texts and enjoy the same achievements, making it more basis and scientific in the selection of visual anthropology in subsequent research. This article comprehensively uses Delphi method and analytic hierarchy process to construct an evaluation system of visual anthropology, as well as put forward the basic principles of screening films using this evaluation system in subsequent studies and a simple outlook for future expansion.

With domestic construction projects becoming bigger, more specialized and more advanced, the construction industry is striving to improve quality and quantity, and is diversifying functions and shapes. Nevertheless, the process of a construction project causes problems when we estimate construction price, because the cost breakdown structures are different in each step. The primary aim of this study was to estimate building life cycle cost using the Delphi method. The cost breakdown structure for life cycle cost was classified into planning, design, construction, maintenance and waste disposal, and each detailed classification was determined by estimating life cycle cost. Moreover, the developed cost breakdown structure is verified by consulting with experts to secure objectivity and validity.

This research suggests the FD-AHP decision making model for Construction Projects which is composed of two main method to prevent a ranking invert situation ; First, to make the consensus of the experts consistent, we utilize Fuzzy-Delphi method to adjust the fuzzy rating of every expert to achive the consensus condition with the fuzzy linguistic presentation. Second, to handle vague linguistic presentation caused by expert's experiences and subjective judgement, we propose Fuzzy-AHP which is able to enhance precision of construction projects decision mating situation. Moreover, with the correlation analysis, we show that the validity of the FD-AHP model under a decision making task specially on where highly demanded expert's experiences and intuition.

This study was carried out to investigate TF(Technological Forecasting) of ISDN (Integrated Services Digital Network) by Delphi method. Since the technology of science has been developed rapidly, the necessity of TF, which can predict the future direction and intensities of technological progress, has been gradually recognized in various fields. Therefore the purpose of this study was to explore the normative statistical data so that our business or nation may have better decision-making with the TF of ISDN which will be come into in the 21st century, presenting the appropriate methodology to the application of methods.

The goal of this research paper is to respond to changing paradigms in urban planning and derive requirements needed for urban archiving for the purpose of urban growth. In this research, the Delphi research method was used twice on experts on urban archiving in order to derive areas and required elements of urban archiving. Moreover, each area and elements were formalized and categorized. The results of this research is as follows. In the 1st Delphi research, 6 areas (natural environment, liberal arts environment, historical and cultural environments, social and educational environment, industrial and economic environment, transportation and communication environment), a total of 62 elements. In the 2nd Delphi research, six areas, a total of 32 elements.
