In order to improve productivity, reduce costs, and improve decision-making efficiency, which are one of the main contents of the digital transformation promotion goal, many companies are promoting the introduction of various IT for digital transformation. Information technology (IT) is a key means of determining competitiveness, and the IT adoption worldwide is increasing every year. The financial industry is also actively introducing huge amounts of IT every year to generate profits, improve work efficiency, and secure a strategic competitive advantage. Compared to some studies on the IT adoption in the public and corporate sectors, empirical studies that reflect the characteristics of the financial industry are insufficient. In this study, the purpose of this study was to derive factors affecting the IT adoption in the financial industry for the promotion of digital transformation, and to analyze weights and priorities. By revealing through data analysis that there is a difference in the relative priorities of factors in the financial IT adoption for each group, it can be used as a reference model for which factors should be considered prior to IT adoption from the perspective of each group. It will be meaningful in that it exists.

Recently, several number of Multi-Intermodal Transfer Center are nominated to improve convenience of public transportation user. Due to budget constraints, it should be defined which is the first consideration among the discussed many works. In this circumstance, there are some absurdities in the evaluation of validity of existing methods. Therefore, we suggested the Priority Order Valuation for Multi-Intermodal Transfer Centerer. The evaluation method, we suggested, is considered quantitative analysis and qualitative analysis. In this study, we find out that B/C ratio and construction costs are strongly related to the quantitative analysis so that Multi-Intermodal Transfer Centers in metropolitan area are evaluated the positive results. Therefore, both quantitative analysis and qualitative analysis are applied to the Priority Order, metropolitan area and other area are fairly evaluated the results for the Priority Order.

전 세계적으로 발생하고 있는 기후변화로 인하여 자연재해가 빈번한 실정이며, 특히 가뭄은 농업용수 부족과 직결되어 식량안보를 위협하는 요소가 되고 있다. 최근 우리나라에서도 통합물관리 정책 추진과 더불어 농업용수의 물절약 필요성이 강조되고 있으며, 농업용수 수요관리를 위한 실사용자인 농업인과 이해관계자들의 관심과 노력이 필요한 상황이다. 따라서 농업용수의 지속가능성 확보를 위한 물이용 절감 등 적극적인 수요관리를 위해 농업용수 거버넌스 구축이 요구되고 있다. 이에 본 연구에서는 우리나라 농업 현장에 적용 가능한 농업용수 거버넌스 구축에 필요한 주요 구성 인자를 파악해 보았다. 이를 위해 국내외의 농업 및 농촌 거버넌스 사례와 문헌조사 등을 통해 농업용수 거버넌스 구축을 위한 6개의 주요 인자를 선정한 후, 전문가를 대상으로AHP(Analytic Hierarchy Process) 방법을 이용한 설문조사 및 쌍대비교를 통해 우선순위를 도출해 보았다. 그 결과, 총 6개 주요 인자의 중요도는 '핵심주체', '법률 및 정책 구축', '예산 지원', '정보공유 및 커뮤니케이션', '상호 학습', '외부전문가' 순으로 도출되었다. 여기서 가장 높은 중요도를 차지한 '핵심주체'는 농업인을 의미하며, 이는 공사에서 담당하고 있는 현재의 공적관리체계로는 필지단위의 효율적 물관리에 한계가 있으므로, 물 사용의 주체인 농업인의 물관리 참여를 위한 거버넌스 운영에 농업인이 핵심주체로서의 역할을 하는 것이 필요하다는 것을 나타낸다. 농업인 중심의 상향식 거버넌스(Bottom-up governance) 방식으로 농업용수 거버넌스가 운영된다면, 농업용수 이해관계자들의 관심과 농업인의 자발적인 물절약 참여를 유도할 수 있을 것으로 판단된다. 또한 거버넌스 운영을 통하여 농업인 및 이해관계자의 소통과 문제 제기 및 환류 노력 등을 통해 물절약을 위한 제도개선 및 현장 실천 노력 등이 지속적으로 이루어진다면, 농업용수 지속가능성 확보에 긍정적인 효과를 나타낼 수 있을 것으로 사료된다.

Multilayer sub-contracting is a significant practice among the world, including Hong Kong. When a principal contractor secured a project from a developer, the specific jobs will usually be breaking down and sub-contractors with the lowest bid [1]. The adoption of multilayer sub-contracting has been a controversy issue which is considered as a two-side blade. While certain studies have been carried out to examine both the contributions, damages and improvements for multi-layer subcontracting, the construction industry and researchers are still waiting for a solid measure to enhance the system. Hence, this research attempts to study the advantages, disadvantages, conducts a comparison between single and multilayer sub-contracting and measures of current Hong Kong construction industry based on literature review, questionnaire and in-depth interviews. To achieve the objectives, Analytic Hierarchy Process (AHP) and total weighted score methods are adopted to examine and rank the criterion. The findings of this study provide a good basis for understanding the major reasons and problems caused by the adoption of multilayer sub-contracting. Besides, the identified safety perspective explores a new perspective regarding to issues of multi-layer subcontracting, which will serve as a solid foundation for further research to enhance safety performance. Finally, the findings of measurements towards improvement of multilayer sub-contracting will also provide a solidsolution for construction industry.

Due to the enhancing environmental concerns worldwide with the need of increasing demand for sustainability of building design, maintenance and operation, key stakeholders including the government and developers in many countries strike for the benefits in implementing the green design and building concepts in constructing, infrastructure as well as the buildings. Different countries have their standards or certifications for green buildings while the adoption rate of BEAM-Plus in HK is relatively less compared with other developed countries such as Europe, USA and Japan. Therefore, in the present research, BEAM-Plus, the beginning assessment method of green standard implemented in HK, will be mainly discussed. Current situation of BEAM-Plus implementation in HK will be reviewed and then adopt a systematic approach via literature review and research paper, questionnaire with Analytic Hierarchy Process (AHP) method to depict the opportunities and challenges from the perspective of government and developers regarding implementing BEAM-Plus in HK and thus investigate the implementation gaps. It is found that for both the macro level of opportunity and challenge, the most important criterion is political, in which the weighting value are 0.3114 and 0.2321 respectively. It is obvious that government plays a critical and significant role in affecting the development of BEAM plus. Technological difficulty is also an important factor that challenging and hindering the implementation of BEAM plus, the weighting value is 0.2194 under challenge hierarchy. More experts and professionals should be imported to Hong Kong to enhance the technique is building green buildings. At the end of this paper, solutions and actions will also be suggested and concluded in alleviating the challenges. Finally, solutions and actions are suggested and concluded in alleviating the challenges. Findings from this research can guide developers to consider adopting green elements, government and Green Building Council in HK to review green buildings' policy.

Research on virtual assets has been mainly interested in policy preparation or legislation for the introduction of virtual assets, or virtual asset operation technology, but this study presents investment factors that most asset investors consider important when making investment decisions. By doing so, we came up with research results that are practically helpful to virtual asset investors. According to the research results, (1) virtual asset investors consider business models such as marketability and competitive advantage of virtual assets as the most important factors, and (2) are highly interested in factors that can be objectively judged when investing in virtual assets. The results of this study suggest that a virtual asset trading market environment that can provide objective investment information and discover various judgment factors that enable virtual asset investors to objectively judge virtual assets should be prepared, and that virtual asset businesses using core technologies will continue to grow. This suggests that a variety of policy support is needed to enable this.

The purpose of information system audit is to proactively identify and efficiently manage all risk factors that may arise during the process of constructing an information system, in order to assist in achieving the objectives of information system development. However, there is currently significant dissatisfaction with the quality and effectiveness of the auditing process, leading to ongoing research aimed at finding effective solutions. In this paper, we propose a multi-level evaluation model to enhance mutual understanding between auditors and evaluators and present a model that undergoes a maturity process, improving its levels and stages. We introduce a maturity-based evaluation model platform, enabling efficient communication between auditors and evaluators, allowing for real-time feedback, and supplementing it through continuous search. By presenting this multi-level model aimed at maturing the entire system, we aim to efficiently manage the system development process.

Korea has studied FTA over 20 years since FTA with Chile. More than 3,000 Articles have been published in journal so far. Thus, this study aims to present the direction that should be taken by Korean FTA study by using Meta-Analysis for FTA study which has been carried on so far. Many researchers publish several articles each year, showing high quotation index and H-index. However, Korean FTA study lacks network with overseas researchers and fusion study with other sciences. 65.4% of Korean FTA study is carried on Independent research and 91.1% of them, in joint research by fewer than 2 persons. Further, the Subject of FTA study is not diverse and too uniform. Out of total studies, 24.3% of them are related to rules of origin and 15.3% of them, to China, showing that theme of study is quite partially concentrated. This is large difference with overseas FTA study. Study on rules of origin is only 1.5% in overseas. Korean FTA study needs to diversify subjects of study and to balance between academic aspect & practical aspect. When it comes to study methodology empirical analysis assumed large portion in both Korea and overseas countries. Empirical analysis assumes 18.3% in Korea and 47.3% in overseas, both of which are quite high. However, qualitative study such as FGI/AHP, in-depth interview, case analysis is quite rare in Korean FTA study. Partial concentration of countries for study subject needs to be rectified also. In Korea, countries for FTA study is China 15.3%, EU 10.0%, USA 6.3%. In overseas, China assumes only 3.7% of study subject. It is required for Korean FTA study to extend study subjects & study area by forming global study network and to extend qualitative study with microscopic study.
