The purpose of this research is to propose policy of domestic timber supply expansion. To recommend polices and draw the priority orders, this study has used Delphi technique and Analytic Hierarchy Process. It has executed to recommend policies of domestic timber supply expand by dividing produce, distribution and consumption parts. As the result of Delphi technique and AHP, 'Infrastructure for domestic timber produce (.239)', 'regional domestic timber gathering complex construction (.202)' and 'a public institution domestic timber use obligation (.126)' policies are derived.

In this study, the performance-based evaluation factors for rock slopes have been deducted using Delphi-method. Validity of the result was verified through factor analysis. Performance of rock slope is classified as soundness, stability and durability. Through the Delphi survey, 17 factors including discontinuity orientation are deducted for soundness, 4 factors and 3 factors are selected for stability and durability, respectively. Validation is conducted using Exploratory Factor Analysis (EFA) for 24 factors, and all factors are found to be valid. As a result of Exploratory Factor Analysis (EFA), 3-types of performance were subdivided into internal soundness, external soundness, risk, damage and durability of slopes and protection (reinforcement) facilities.

특정분야의 기술에 대한 중요도를 평가할 경우 일반적으로 해당 분야 기술의 전문가들의 의견을 델파이 방법을 이용하여 수렴하고 AHP 분석을 통해 기술의 우선순위를 결정하곤 한다. 그러나 전문가들의 직관적 판단에 의존하는 델파이 기법과 AHP 분석은 전문가 집단을 어떻게 선정하느냐에 따라 다른 결과를 초래하거나 항상 최적의 대안을 제시한다는 보장을 하지 못하므로 이에 대한 보완이 필요하다. 본 연구는 해당 기술 분야의 객관적인 자료인 특허 문서를 분석하여 델파이를 통해 도출된 전문가들의 기술 평가 결과의 타당성을 확인하도록 특허맵 분석을 활용할 것과 많은 대상 기술과 다양한 기술 평가 기준을 한꺼번에 고려하여 기술간 우선순위, 기술간 유사성, 기술군간 관련성을 쉽게 확인할 수 있는 SOM 신경망 분석을 활용할 것을 제안한다.

2012년 8월 "소방공무원 보건안전 및 복지 기본법"의 시행으로 소방공무원에 대한 보건안전과 복지에 대한 기본적 법규가 마련되어 현재까지 시행되어오고 있다. 이 법에 근거하여 소방청장은 5년마다 소방공무원 보건안전 및 복지기본계획을, 그리고 매년 연도별 계획을 수립하여 시행하고 있다. 본 연구는 이러한 정책들이 실질적으로 소방공무원의 보건과 복지에 기여하는지 여부를 실증검증하기 위해 현황분석과 더불어 해당분야 전문가들로부터의 델파이분석기법에 의해 현재 계획에 근거한 정책들의 문제점과 개선방안을 도출하고자 한다.

4차 산업혁명 시대에 접어 들어 불확실성이 높아지고 변동성의 상시화로 세계 경제가 급변하면서, 기업가정신 교육의 중요성은 점점 더 높아지고 있다. 이러한 시대의 흐름에 따라 최근 청소년 기업가정신 교육이 확산되었다. 지속가능한 청소년 기업가정신 교육이 이루어지기 위해서는 시대의 변화와 함께 부모들의 인식과 태도도 함께 변화해야 한다. 부모는 새로운 지식과 그 시대가 요구하는 바람직한 자녀관을 형성해야 하며, 사회 전반적인 변화에 따른 학교에서의 기업가정신 교육이 가정에서도 일관성 있게 유지되어야 한다. 이에 본 연구는 부모교육의 중요성을 확인하고, 교육을 통해 부모의 인식을 변화시키기 위해 필요한 역량 도출하기 위해 델파이 조사를 실시하였다. 기업가정신 교육 전문가와 청소년 교육 전문가로 구성된 전문가 패널들을 대상으로 3회에 걸쳐 델파이 조사를 실시하였다. 델파이 조사 분석 결과, 부모 인식 전환을 위해 필요한 최종 8가지 역량(환경의 변화, 도전정신, 주체성/자울성, 창업에 대한 이해, 직업의 다양성, 기업가정신에 대한 이해, 개인의 다양성, 팀/협업에 대한 가치)을 도출하였다. 향후 후속 연구를 통해 도출된 역량을 함양할 수 있는 부모 기업가정신 교육 모델 및 프로그램을 설계하고자 한다.

This research aims to define influence factors to perform an optimized section design and evaluate tunnel collapse risk during construction using Delphi technique. A total of five upper classification systems were constructed through literature review, pervious research analysis, and brainstorming of expert group for establishing influence factors. The $1^{st}$, $2^{nd}$, and $3^{rd}$ Delphi survey process was proceeded by panel group which is consisted 21 experts to prevent errors and bias in the expert judgement process. In Delphi $1^{st}$ survey, a total of 22 influence factors candidates were derived through open-ended questionnaire. In Delphi $2^{nd}$ survey, questionnaire was proceeded based on 7-point Likert scale method. In order to verify the validity, CVR (Content Validity Ration) analysis was performed to exclude inappropriate candidates. In the $3^{rd}$ survey, verification of influence factors was proceeded once more with the result of $2^{nd}$ survey, and lastly, a total of 14 influence factors was derived by CVR and COV (Content Validity Ration) analysis for response of experts.

In this study, the Delphi method and AHP (analytic hierarchy process) were used to evaluate tunnel collapse risk from a comprehensive and multifaceted perspective. Influence factors were established through literature reviews, previous studies, and brainstorming sessions with expert groups, resulting in the construction of five main classification systems. A panel of 21 experts was formed, and three rounds of Delphi surveys were conducted to prevent errors and biases in the expert judgment process, thereby enhancing reliability. Ultimately, 14 influence factors were identified through CVR (content validity ratio) and COV (coefficient of variation) analyses of the experts' responses. Subsequently, the AHP method was applied to assess the relative importance of each influence factor and calculate the final composite weights. The timing of support and reinforcement had the highest priority, followed by groundwater inflow, joint conditions, support pattern levels, and auxiliary methods. These findings help identify the key factors affecting tunnel collapse risk and provide a foundation for developing strategies to improve tunnel safety.

Based on the service scenario proposed by the existing Kim Tae-wan (2018) who can safely evacuate inmates with the help of a mobile application linked to a fire detection system in the event of a fire, the final purpose of this study is to develop the scenario by incorporating more realistic scenarios with mobile stimuli that can help them escape or act through the Delph In addition, to make the scenarios produced more realistic considering the structure and copper lines of a typical building, expert scenario verification and Delphi technique were applied to exclude unnecessary or impractical aspects of the existing scenarios. The results of the second Delphi survey showed that the primary psychology that could be seen at the time of the fire alarm were doubts, safety concerns and alarm, and the results of the second Delphi survey were analyzed, and the satisfaction of the content adequacy (CVR), convergence, and consensus was derived. Finally, this was applied to create a scenario in which a mobile application was assisted to evacuate the fire response phase. This study will allow the use of methods to increase the evacuation rate of those who are in the event of a fire.

This study aims to explore a set of indicators to be used for purification management. by estimating the total quantity of depositied waste in coastal waters, Through 3 rounds of Delphi technique, this study sorts out the following 5 variables to be used as major indicators determining priorities for purification in coastal areas: the ratio of re-deposition after collection, the area where fishing gear are lost, the total quantity of depositied waste of each coastal water, the total quantity of deposited waste in the past, and the quantity of depositied waste by unit area. Although the fact that the delphi surveys were done only on 27 specialists limits its external validity, this study will serve as a base for in-depth studies with more expanded panels that will provide better indicators for purification management in coastal waters of Korea.

This research is the first research on developing the speed limit select model and also it is the result of the research on the importance of each element and consideration factors when selecting the speed limit. For the consideration factor discrimination and calculation of the importance, the delphi method and AHP method was used. The delphi survey was processed through third round survey, 5 high consideration factor(Level 1) and 23 low consideration factor(Level 2) was discriminated. During the process of the third delphi survey, when the CVR cost was in the range between 0.4~1.0 it was treated as the consideration factor when selecting the speed limit and less than 0.4 cost was eliminated. In the process of the second delphi survey, 33 consideration factors were discriminated but was reordered into 23 categories through the third survey. Based on the 23 categories earned through the third delphi analysis, the AHP survey was processed. The result of the AHP survey was that out of the importance of the 5 high consideration factor(Level 1), the traffic condition was evaluated as the number one factor and the vessel condition, waterway condition, environment condition, supporting condition and etc. conditions were evaluated following the traffic condition. Out of the 23 low consideration factor(Level 2) consideration, the visibility was evaluated to be the first important and the performance of the vessel steering, objective factors within the harbor, amount of traffic and density, distance between the passing vessel, speed of the steering capacity and tidal current were the following evaluated factors.
