Protective facilities are the last means of ensuring the survivability of personnel and assets, and there is a greater amount of matters to consider than those of general buildings. However, the Defense Military Facilities Criteria and the Ministry of the Interior and Safety, Ordinance No. 20, are only considering the expected enemy threats. In this study, we use objective and statistical methods to refine the consideration of the required capacity of protection based on the opinions of the experts. Specifically, the study adopts the Delphi technique associating the experts related to 30 defense military facilities criteria. The first-round questions were open-ended, and it compiled the points to consider related to the bulletproof and explosion - proof design. The second questionnaire was applied as closed questionnaire with 7 points scale methods. As a result of the factor analysis on the opinions of the experts, it was confirmed that the protection requirement level was due to METT + TC.

The digital transformation of the shipbuilding, shipping, and logistics sectors is predicted to lead to the introduction of autonomous ships and changes in the way ships are operated. The co-existence of various operation forms, such as autonomous operation and remote operation, with the existing operation methods is expected to lead to the transformation of the ship operation process and the emergence of new stakeholders. This paper studies the future ship operation process according to the change in ship operation method, predicts the change in the operating environment of future ships, and derives functional requirements by major tasks and stakeholders. The Delphi technique is applied to construct a ship operation scenario from the planning stage of voyage and cargo transport to the stage of arrival at the final destination port and discharge of cargo, and to predict future work changes by task and actor. Seafarers' activities are expected to be minimised by remote and autonomous operation, and experts in each field are expected to have responsibilities and tasks in different aspects of ship operation.

In this study, I examined the problems of the current barista curriculum and sought how to improve them by feedback from domestic specialized baristas and comparative analyses of the training programs that take place in barista educational institutions. In order to identify problems in curriculum and what to be improved, I gained the opinions of 15 experts who are currently teaching students in barista educational institutions using Delphi technique. To sum up the opinions of experts, working level education of coffee has to be mainly done and substantial educations for employment such as cafe operating technique and marketing are needed. In addition, experts suggested enhancing service courses considering the nature of working in contact with customers and the course for baking goods that takes up a lot of sales. As a result of examining the current curriculum in the institutions for baristas, it seems necessary to supplement these training courses that experts suggested because the educations are very poor.

This study is based on ERIS model for start-up performance, and aims to derive the main reason for start-up sustainability centered on organizational resilience. To this end, systematic literature examination and modified Delphi method were used to investigate start-up sustainability factors based on ERIS Model focused on organizational resilience. The results showed that ERIS model-based entrepreneurial continuity factors were divided into four categories: entrepreneur, resource, industrial environment, strategy, subdivision 8 and detailed factors 54. In addition, the ERIS model-based continuity factors were structured around organizational resilience, and the continuity factors were structured according to ERIS model under five categories: leadership, culture, people, system and environment. The results of this study are as follows. First of all, the results of existing research and analysis show that the concept of successful start-up and sustainability of start-up are used in various fields. Second, it is confirmed that there are common factors of influence on start-up performance and start-up sustainability based on ERIS model. Third, Delphi method's results showed that the general characteristics of entrepreneurs, such as academic background, education level, gender, age, and business experience did not affect the sustainability of entrepreneurship. This study is significant in that it is based on ERIS model focused on organization resilience, and ERIS-R, which integrates Strategy into System and Organization resilience into R in the field of gradually expanding start-up development and support. It is expected that the results of this study will improve the sustainability of start-up that can predict, prevent, and overcome various crises at any time.

유역의 홍수위험도를 평가하기 위하여 선행 연구로서 DPSIR framework를 적용한 인자를 선정하였다. 이때 인자의 범위를 사회적, 경제적, 환경적 분야로 구분하고 각 분야에 대하여 홍수로 인하여 야기되는 유역의 다양한 영향요소를 포함하여 인자를 선정하였다. 본 연구에서는 이를 대상으로 각 인자의 가중치를 선정하기 위하여 패널식 조사연구기법인 Delphi 방법을 적용하였다. Delphi 기법은 델파이 절차가 반복되는 동안 조사 참여자에게 전회의 조사 결과, 즉 통계적 집단 반응을 피드백하며 참여자는 이를 참고하여 자신의 판단을 수정 보완 할 수 있는 방법이다. 따라서 1차 설문조사를 통하여 각 패널은 홍수위험도 평가 인자에 대해서 주관적인 가중치를 선정하고 이를 분석한 결과를 피드백 받아 참고한 후 2차 설문조사에 응하여 가중치를 재선정하게 된다. 조사에 참여할 패널의 선정은 수자원분야의 전문가를 대상으로 하였다. 또한 각 인자에 대한 가중치를 수집하는 방법을 다양하게 설정하여 기법에 따른 영향을 검토하였다. 수집기법은 상대적 가중치 결정법 중에서 가장 많이 사용되는 순위법과 직접입력법, 절대적인 기준에 대한 가중치를 수집하기 위하여 Fuzzy 가중치 입력법을 사용하였으며 이 때 각 인자가 소속되는 분야와 DPSIR framework 요소에 대해서도 별도로 가중치를 수집하여 최종적인 인자의 가중치를 결정하였다. 본 연구는 추가 연구를 통해 남한강에 적용되며 인자의 자료는 문헌조사, 통계자료 조사 및 수리학적 수치모형 등의 분석을 통해 수집될 예정이다. 이를 통하여 사회, 경제, 문화, 환경적인 측면을 고려한 인자들을 반영한 하천의 구간별 상대적 홍수취약도를 정량적으로 제시할 수 있으며 하천 구간별 치수관리 우선순위를 결정하는데 적극적으로 활용될 수 있다.

Integrated concepts that are broad enough to embrace facts, principles, laws, and concepts of multiple disciplines could become the core of integrated education. Integrated concept-centered education enables effective and practical learning. In this study, the Delphi Method was implemented targeting experts in science (physics, life science, chemistry, and earth science) and humanities (history, geology, economics, ethics, and politics) to find out the integrated concept that can be used to design the concept-centered integrated education in the Republic of Korea. 124 experts participated in this survey. Delphi survey was conducted for three rounds. In the first round, an open questionnaire was given to experts to collect feasible integrated concepts in each major field. Then, in the second round experts were asked to select integrated concepts that could be used practically in the field of their major. In the third round, the integrated concept with selection frequency over medium value were given. They were asked to evaluate the applicability of integrated concepts by using the Likert-scale questionnaire. Through this process, content validity was analyzed. As a result, five integrated concepts (change, interaction, space-time, energy, and equilibrium) were selected for the inter-science integration. And thirteen integrated concepts (conflict, community, relationship, structure, power, diversity, culture, change, society, interaction, freedom, justice, and equality) were chosen for the inter-humanities integration. Finally, for the science-humanities integration, seven integrated concepts (structure, diversity, change, interaction, cycle, system, and environment) were determined.

Considering about construction projects characteristics, there Is an existing uncertainty which causes inaccuracy or invalidity under decision making situation. Therefore, cost risk analysis of numerous construction projects are Inclined to depend on expert's experiences and subjective judgements. In Korean domestic construction works, however, there is no reasonable method or process for applying subjective elements. Only probabilistic analysis using objective calculation are being used now. This research suggests a cost risk analysis method to analyze quantitatively Cost Impact by risk, and it appraises expert's subjective elements for the purpose of enhancing validity of cost estimation. Moreover, a new cost risk analysis method is introduced for providing convenient user interface in practical business.
