Demand for NFT is expanding along with Blockchain. And cyber security threats are also increasing. Therefore, this study derives security level inspection items by analyzing status related to NFT security such as NFT features, security threats, and compliance for the purpose of strengthening NFT security. Based on this, the relative importance was confirmed by applying it to the AHP model. As a result of the empirical analysis, the priority order of importance was found in the order of Security management system establishment and operation, encryption, and risk management, etc. The significance of this study is to reduce NFT security incidents and improve the NFT security management level of related companies by deriving NFT-related security level check items and demonstrating the research model. And If you perform considering relative importance of the NFT check items, the security level can be identified early.

물부족 철상은 심자한 사회적 문제로 대두되고 있으며, 이를 대처하기 위한 방안으로 지표수-지하수 연계 이용에 대한 연구가 진행되고 있다. 지표수와 지하수를 연계이용 하는 방안 중 강변여과수는 강변에 분포되어 있는 충적층에 강물을 통과시켜 취수하는 것으로 수질과 수량을 동시에 해결할 수 있다고 알려져 있다. 최적의 강변여과수 취수지점을 선정하기 위한 첫 단계로 어느 지역이 적합한 지 그 여부를 판단할 필요가 있으며, 경우에 따라서는 복수 지역의 우선 순위를 결정하는 것이 요구될 때도 있다. 본 연구에서는 강변여과수 개발지역 적지분석을 위해 복잡한 의사결정 문제를 계층적으로 나누어 분석하는 기법인 계층분석과정(AHP)을 이용하였고, 분석에 필요한 의사결정인자를 도출하였다. 그리고 각 인자의 상대적 중요도를 정량화 한 후, 이를 바탕으로 강변여과수 개발을 위한 적지를 산정하였다.

에너지 해외 의존도의 경감, 그리고 국제적인 환경규제에 대처하기 위하여 신재생에너지 가운데 하나인 소수력의 개발이 에너지문제의 대안으로서 부각되고 있다. 일반하천에서 소수력의 성공적인 개발을 위해서는 기존의 수자원 개발 계획과 마찬가지로 경제성을 기초로 한 자원의 효율적인 이용 및 개발에 따른 인문 사회 환경적 영향 등과 같은 체계적인 적지분석이 선행되어야 한다. 그리하여 본 연구에서는 소수력 개발 대상 지점에 대한 유황 및 지형분석을 위해 SWAT 모형과 GIS TOOL을 이용하였고, 소수력 모의발전 및 경제성분석에 의해 최적규모를 결정하였다. 그리고 AHP 방법에 의한 평가항목의 가중치 결정 및 대안 별 평가에 의해, 보다 합리적인 의사결정을 하고자 하였다. 이러한 일련의 과정을 금강 보청천 유역에 적용하였고, 총 7개의 지점에 대한 개발 우선순위를 도출하였다.

The primary purpose of this paper is to find out what issues are important in the Social Security sector, and then, through AHP methodology, this study analyzes what kind of big data methodologies and projects can be implemented to solves these issues. To the aim, this paper first confirmed 8 big data projects from reviewing all issues in the Social Security sector such as administrative works and social policies. After the result of pairwise comparison, policy validity is most important factors rather then effectiveness and practicability. With regard to the priorities among sub-big data projects, the project about preventing improper recipients has come out the most important project in terms of validity, effectiveness and practicability. And the results showed that the project about outreaching and reducing a blind spot on the welfare sector is weighed as a significant project. The results of this paper, in particular 8 sub-big data projects, will be useful to anyone who is interested in using big data and its methodologies for the social welfare sector.

Length and the number of tunnels has increased 10% annually. Tunnel construction has positive effect in nature and driving condition. However, the structure of tunnels lead to a greater probability of major accidents. For this reason, tunnel is focusing its attention on the rapid incident handling and disaster management to build a tunnel management system in recently. In this study, tunnel management system adequacy analyzed in terms of operational safety using IPA and AHP analysis. IPA analysis results using the portfolio chart, incident management factors has a large gap between important and satisfaction. Disaster management is analyzed high ranking in priority. However, incident management factors are derived first priority in AHP analysis. This study determined that the results are meaningful to practitioners in the field is determined. In addition, practitioners comments should be reflected primarily for tunnel operational safely.

This study analyzes Korea's Free Economic Zone (FEZ), by particularly focusing on Incheon and Busan-Jinhae zones, using the Analytic Hierarchy Process (AHP) method and a questionnaire survey analysis. The study compares important selection criteria and satisfaction of resident companies in Incheon and Busan-Jinhae FEZs. The findings are as follows. First, the AHP method results suggest that companies in both Incheon and Busan-Jinhae FEZs are affected by location, economic society, and policy. In subordinate determining factor for land, it is ordered by ease of gaining land, inexpensive rental fee in Incheon and by convenient access to close markets and inexpensive rental fee in Busan-Jinhae. Second, the questionnaire survey results suggest high adjacent market size and easy access in Incheon FEZ and sound logistics infrastructure in Busan-Jinhae FEZ. For this reason, Incheon has a high value of logistics infrastructure and potential market near metropolitan area and Busan-Jinhae, has a high value of transportation Infrastructure near industrial district. These findings will contribute to policy data for activating and promoting the Free Economic Zone.

This study aimed to determine the importance of the policies formulated through the Ministry of Maritime Affairs and Fisheries' master plan for Seafarer's policy. To confirm the importance of the Seafarer's policy, AHP analysis was conducted on the 3 main policies and 15 auxiliary policies established by the master plan for Seafarer's policy. To analyze the reliability of the survey, we investigated the inconsistency ratio of 34 respondents retrieved. We found that 25 respondents validated the reliability of the findings. The analysis showed that the policy of establishing a stable supply and demand system was the most important among the main policies for seafarers, while the policy of fostering seafarers linked to jobs was the most important one among the auxiliary policies. By group, the government recognized establishing a stable supply and demand system as a priority of policy. Dif erences were found on the fact that improving working conditions and expanding welfare were important for seafarers. This study, which analyzed the importance of the Seafarer's policy through AHP analysis, has the following implications. We established guidelines to enhance efficiency, such as budget allocation by policy according to the importance in implementing Seafarer's policies. Furthermore, our study can be used as basic data for establishing a master plan for Seafarer's policy by comparing differences in importance per group.

The 21st century recognizes culture as a high value-added strategic industry as it is called the culture era, and the cultural industry plays a role in driving regional economic development by raising the value added of other industries due to various ripple effects. As the institutional apparatus for developing such cultural industry, the Culture Industry Promotion Basic Law was enacted. Based on this, the Central Government designated the Jung-gu Dong and Seo-gu Dong as the Cultural Industry Promotion District of Andong City in 2010 but it has not been activated until 2017. The purpose of this study is understanding the situation and problems of the Cultural Industry Promotion District of Andong city and to discuss the direction of development. The research methods were analyzed by using questionnaires using AHP analysis technique for experts and practitioners related to culture industry. SPSS 23 was used for the validity and reliability of the questionnaire, and VBA was used for weighting and consistency index calculation in AHP analysis. As a result in the upper layer, Economy efficiency was found to be the most important factor of the three upper layer factors (Economy, Publicity, and Sociality) in order to activate the Cultural Industry Promotion District of Andong city. In the case of the Lieutenant layer, it is analyzed that the Job Creation is an important factor in the Economy category, the Settlement and Environment for Cultural Industry in the Publicity category, and the Activation of Urban Culture Activity in the Sociality category. As a result of analyzing the direction of promotion of the Cultural Industry Promotion District of Andong City centered on these factors, it concluded that the industry related to performance should be focused.
