  • Recently, low hydrogen carbon production technology is drawing interest due to lower production costs. Although the pace of research in this field has been accelerating, there is no well-established criteria for evaluation. The most of current evaluation methods needs information related to technology. However the technology is not enough to provide effective evaluation criteria because the technology is not fully developed. In this study, we propose an integrated Delphi-analytic hierarchy process (AHP) method and low carbon hydrogen production technology evaluation model. Experts opinion is used to provide evaluation criteria for the technology. In this study, integrated Delphi-AHP method are utilized for determining factors and calculating their numerical importance based on experts opinion. Then, sensitivity analysis is performed to verify the robustness of the analysis and scenarios of potential changes. As many as 11 factors are identified by Delphi method. Then, numerical importance of the factors are calculated by AHP. Sensitivity analysis is performed. It shows that intellectual property right (IPR) is always more important than other factors. This study proposes the numerical standard for the low carbon hydrogen production technology evaluation. The proposed model can be used for technology evaluation or commercialization.

  • Purpose: The purpose of this study was to develop content for safety education to prevent hospital safety accidents among hospitalized children and to investigate the status of safety education performed by nurses. Methods: First, the Delphi method was used, with 18 experts, to develop educational contents for preventing safety accidents. Second, an exploratory survey was performed of the actual status of safety education for preventing safety accidents among hospitalized children using a questionnaire developed based on the Delphi method. The participants of this study were 159 nurses with at least 6 months of work experience. Results: The educational content developed through the Delphi method for preventing safety accidents among hospitalized children contained seven domains (falls, injury, electric shocks/burns, suffocation/aspiration, poisoning/abuse, kidnapping, medical devices) with 44 topics. The item mean of nurses'perceptions of the importance of child safety education was 4.18, and the actual performance score was 3.72, which was a statistically significant difference (t=11.58, p<.001). Conclusion: These seven comprehensive domains of accident prevention education for hospitalized children are expected to be useful for interventions to support the safety of hospitalized children.

  • Objectives: The aim of this study was to establish a clear diagnostic definition of Sanhupung using the Delphi method. Methods: This study used the Delphi technique. A panel consisting of 21 experts of Korean medicine, particularly in of gynecologic medicine, participated in the Delphi examination that included answering the 4th round survey. The Delphi examination was carried out through evaluating and correcting the questionnaire by e-mail. Results: Through the Delphi survey, we have reached on an agreement regarding the basic concepts, time, cause, essential symptoms, and accessory symptoms of Sanhupung. They are as follows: 1) Sanhupung is a culture bound syndrome reflecting Korea's cultural specificity. 2) Sanhupung can be diagnosed even after the miscarriage. 3) For the diagnosis of Sanhupung, the main cause of symptoms should not be classified as other disease. 4) Sanhupung can be diagnosed based on essential symptoms and accessory symptoms. 5) Essential symptoms include local symptoms such as joint pain at specific areas, partial sensory impairment and general symptoms including pain of all the joints, whole body sensory impairment, increased sweating, feeling of wind coming into the body, worsened symptoms with the cold, intolerance to cold, and pain of all the muscles. Conclusions: The basic concepts and diagnostic definition of Sanhupung were suggested based on the Delphi survey among experts in the field. Further research is necessary to improve reliability and validity of diagnostic definition of Sanhupung in clinical trials.

  • 기후변화로 인한 이상기후 현상 중 가뭄에 대한 취약성 지수를 자료의 경향성 분석과 Delphi 기법을 이용하여 개발하였다. 낙동강 유역 자료를 이용하여 수문학적, 강우 사상적, 인문학적 자료를 바탕으로 총 12개의 지표를 선정하였다. 선정된 지표를 Mann-Kendall trend test, Hotelling-Pabst trend test, Sen's trend test 등 3가지 경향성 검정을 통해 표준화하고, 델파이 기법을 통해 국내의 수자원 전문가들의 의견을 반영하여 각 지표에 가중치를 부여하였다. 최종적으로 산출된 가뭄에 대한 취약성 지수에서 낙동강 유역 중에서 합천 주변 지역이 가뭄에 가장 취약하다는 결과가 나왔다. 이 취약성 지수 개발을 통해 우리나라 전 지역에 적용하게 되면 향후 수자원 정책 수립에 있어서 많은 도움이 될 것이라 사료된다.

  • 우리나라는 아직 체계적이고 표준화된 정보과학 영재교육과정이 없으며 이는 주로 속진으로 운영되는 교육과정의 문제점과 연결되어 있다. 따라서 정규 교육과정과 연계된 영재 교육과정과 간학문간의 다양한 심화를 통한 학습이 필요하다. 본 연구의 목적은 중학교 개정 '정보' 교육과정과 연계하여 정보영재를 위한 심화 교육과정을 개발하는 것이다. '정보' 교육과정 중 '문제해결방법과 절차' 영역을 대상으로 교육 목표, 교육 내용, 교수 학습 방법, 교육 평가 방법의 교육과정을 구성하기 위해 델파이 연구를 진행하였다. '문제해결방법과 절차' 영역의 1단계를 대상으로 3라운드 델파이 조사를 실시하였다. 전문가의 응답을 분석하여 구조화된 문항을 설계하였고 기술 통계를 사용하여 교육 목표, 교육 내용, 교수 학습 방법, 교육 평가 방법에 대한 중요 항목을 선정하였다.

  • The flow of the $4^{th}$ Industrial Revolution calls for the innovation of the traditional business models of the manufacturers. Servitization is a corporate strategy to respond to changes in the business environment. These days, the value that the market demands can be created on the basis of the product-service integration. Thus the manufacturers must pursue the fundamental innovation of the current strategy and business models. It is necessary to create common values with customers through providing product-service integrated offerings beyond the development, production, and delivery. The purpose of this study is to develop the evaluation indicators for selecting suppliers when the manufacturer who offers the value of product-service integration needs to obtain the resources from outside. The case company in this study is the manufacture firm conducting the retail IoT business as a new business. The Delphi method is used to develop the evaluation indicators for selecting suppliers. This study suggests the academic implications providing the perspective of Servitizaiton by using Delphi method, and the practical implications applying the creating value method of Servitization by collecting the opinions from both value providers and value consumers in the process of developing the evaluation indicators.

  • We provide a set of information on technologies to draw meaningful action plans for the internationalization on National R&D activities. In this study, we employed a modiffed Delphi method to evaluate levels of our technological capabilities and developed countries as well. We investigated technology acquis- tion methodologies, technology characteristics and various aspects of international cooperation in terms of technology. Then, we analyzed final responses of participants (i.e., the third round results of Delphe method) to see the correlation among various factors in developing technologies through international R&D cooperation. The technology classification used in this research was developed by STEPI (Science and Technology Policy Institute). In conclusion, levels of our technologies were investigated to be between the stage of imi- tating/absorbing advanced thechnologies and the stage of digesting acquired technologies. Especially, com- paring with other technologies, mechanical engineering was evaluated to be almost near the stage of digesting acquired technology(the middle level stage of technology). Our overal technological capabilities were evaluated to be 40 .approx. 60% of top level countries.
