Finding a root cause is an essential step to solving a complex problem. Some previous studies have used the Delphi method for gathering opinions about root causes from geographically dispersed experts. However, we assert that complicated problems such as an industry ecosystem would make a general type of the Delphi method less practical because of too much psychological burden on study participants. In this study we present a preliminary list-based Delphi study method for identifying a root cause. This method was used to identify a root cause and draw a causal map for the information industry ecosystem problems.

Purpose: To find out whether the self-care ability measurement used for visiting health care provide an appropriate standard to select service methods using a Delphi survey and to offer basic data that can improve the measurement. Method: A Delphi survey was done with 39 people consisting of theoretical professionals, field managers, and practitioners engaged in visiting health care. Result: It was found that items and weighted points in the currently used self-care ability measurement needed adjustment. Therefore, a modified evaluation standard was presented by domains, items and detailed items. Finally, the self-care ability measurement is composed of 4 domains, 11 items and 19 detailed items. Conclusion: This study is significant in that it presented an evaluation standard applicable directly to business practice by supplementing problems in the existing self-care ability measurement. This study suggests the need to develop various measurements for elderly households based on community.

Since 'The Act on Private Investment of The Infrastructure' was established in 1994, private investment as well as government's investment in transport infrastructure has been active. However investment in transport infrastructure has more risks than others' due to uncertainty both in traffic volume and in construction cost. In the current appraisal procedure of deciding transportation infrastructure investment, instead of risk management, the sensitivity analysis considering only the changes of benefit, cost and social discount rate which are main factor affecting economic feasibility is carried out. Therefore the uncertainty of various factors affecting demand, cost and benefit are not considered in feasibility study. In this study the problems in current investment appraisal system were reviewed. Using Delphi technique the major factors which have high uncertainty in feasibility study were surveyed and then improvement plan was suggested in the respective of classic 4 step demand forecasting method. The range estimation technique was also mentioned to deal with the uncertainty of the future.

The purpose of the Delphi technique is to elicit information and judgments from participants to facilitate problem-solving, planning, and decision-making. It does so without physically assembling the contributors. Instead of it, information is exchanged via mail, FAX, or email. This technique is designed to take advantage of participants' creativity as well as the facilitating effects of group involvement and interaction. It is structured to capitalize on the merits of group problem-solving and minimize the liabilities of group problem-solving. In this paper, we design and implement delphi system using instant messenger.

The purpose of this study was to establish a Korean reading ability assessment category based on a reading comprehension theory, and to establish an evaluation framework for Korean reading ability after creating the evaluation factors corresponding to each category through expert Delphi survey. The three levels of reading comprehension that were constructed are the following: language knowledge, text comprehension, and interpretation and comprehension of new ideas and application. This study suggested that constructs of Korean reading assessment reflected reading theory. This study has meaningful consequences which suggest verified constructs through Delphi surveys.

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.

With rapid advance of technologies including information and communication technologies, jobs are evolving faster than ever. Architectural engineering is no exception in this regard, and the green architectural engineering is emerging fast as a promising new field. In this study, a Delphi study of expert architectural engineers are conducted to find out (1) near future prospects of the field, (2) near future emerging jobs, (3) competencies needed for these jobs, and (4) educational content necessary to build these competencies with regards to the green architectural engineering. Initial Delphi survey consisting of open-ended questions in the above four areas were conducted and came out with 65 items after duplicate removal and semantic refinements. Further refinements via second and third wave of Delphi results into 40 items that the 13 architectural engineering experts may largely agree upon as future prospects with regards to the green architectural engineering. Findings indicate that it is expected that the demand for green architectural engineering and needs for automatic energy control system increase. Also, collaborations with other fields is becoming more and more important in green architectural engineering. The professional work management skills such as knowledge convergence, problem solving, collaboration skills, and creativity linking components from various related areas seem to also be on the increasing need. Near future ready critical skills are found to be the building environment control techniques (thermal, light, sound, and air), the data processing techniques like data mining, energy monitoring, and the control and utilization of environmental analysis software. Experts also agree on new curriculum for green building architecture to be developed with more of converging subjects across disciplines for future ready professional skills and experiences. Major topics to be covered in the near future includes building environment studies, building energy management, energy reduction systems, indoor air quality, global environment and natural phenomena, and machinery and electrical facility. Architectural engineering community should be concerned with building up the competencies identified in this Delphi preparing for fast advancing future.

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.
