Recently ICT, new technologies such as IoT, Cloud, and Artificial Intelligence are changing the information society explosively. But personal information leakage incidents of consignee's company are increasing more and more because of the expansion of consignment business and the latest threats such as Ransomware and APT. Therefore, in order to strengthen the security of consignee's company, this study derived the checklists through the analysis of the status such as the feature of consignment and the security standard management system and precedent research. It also analyzed laws related to consignment. Finally we found out the relative importance of checklists after it was applied to proposed AHP(Analytic Hierarchy Process) Model. Relative importance was ranked as establishment of an internal administration plan, privacy cryptography, life cycle, access authority management and so on. The purpose of this study is to reduce the risk of leakage of customer information and improve the level of personal information protection management of the consignee by deriving the check items required in handling personal information of consignee and demonstrating the model. If the inspection activities are performed considering the relative importance of the checklist items, the effectiveness of the input time and cost will be enhanced.

Many major country have struggled to build a block of the secondary battery industry supply chain by considering their interests first. And their supply chain due diligence agreement mandates due diligence on human rights and environmental risks that may occur throughout the supply chain. So the integrated approach called supply chain ESG is needed. But there isn't to be a global standard for ESG yet. And the disclosure standards for each country are different, adding to companies' confusion. In this perspective, to present guidelines for establishing a supply chain ESG management strategy accompanied by Korean SMEs, this study presents environmental evaluation indicators of global secondary battery supply chain ESG customized for Korean SMEs and then performs weight analysis using AHP methodology. Through this, this study aims to suggest implications for accepting sustainability within the supply chain of Korean SMEs by presenting indicators to be considered first among environmental evaluation indicators in preparation for ESG due diligence of the global secondary battery supply chain.

Overall risks that can occur in a shield TBM tunnelling are studied in this paper. Both the potential risk events that may occur during tunnel construction and their causes are identified, and the causal relationship between causes and events is obtained in a systematic way. Risk impact analysis is performed for the potential risk events and ways to mitigate the risks are summarized. Literature surveys as well as interviews with experts were made for this purpose. The potential risk events are classified into eight categories: cuttability reduction, collapse of a tunnel face, ground surface settlement and upheaval, spurts of slurry on the ground, incapability of mucking and excavation, and water leakage. The causes of these risks are categorized into three areas: geological, design and construction management factors. Bayesian Networks (BN) were established to systematically assess a causal relationship between causes and events. The risk impact analysis was performed to evaluate a risk response level by adopting an Analytic Hierarchy Process (AHP) with the consideration of the downtime and cost of measures. Based on the result of the risk impact analysis, the risk events are divided into four risk response levels and these levels are verified by comparing with the actual occurrences of risk events. Measures to mitigate the potential risk events during the design and/or construction stages are also proposed. Result of this research will be of the help to the designers and contractors of TBM tunnelling projects in identifying the potential risks and for preparing a systematic risk management through the evaluation of the risk response level and the migration methods in the design and construction stage.

With the advancement of Fourth Industrial Revolution technologies, the maritime sector is actively developing technologies and policies related to autonomous ships. This study aims to identify and prioritize various factors influencing the adoption of Maritime Autonomous Surface Ships (MASS) by conducting surveys among experts and professionals in the maritime industry. To achieve this, relevant factors related to the adoption of autonomous ships were examined through a review of previous research, and survey questions for pairwise comparison using the Analytic Hierarchy Process (AHP) were developed based on the insights of industry experts. The pairwise comparison items were categorized into four main factors at the highest level, with each factor further subdivided into sub-factors to establish their priorities. The survey results, which distinguish between shipowner and non-shipowner groups, reveal that, among the main factors-economic, legal and policy, safety and security, and technical-the shipowner group prioritized economic factors, though the difference from safety and security factors was relatively minor. In contrast, the non-shipowner group rated safety and security factors as the highest priority, with economic factors ranked lowest. Further analysis of the sub-factors across both groups indicated that, for economic factors, the increase in operational profit was most critical; for legal and policy factors, regulations related to structural equipment were paramount; for safety and security factors, the risk of equipment and machinery failure was key; and for technical factors, accident response technology was most significant. This study provides strategic insights for stakeholders by systematically analyzing decision factors for adopting MASS through AHP analysis. The findings enable companies to establish efficient resource allocation and investment strategies, while policymakers can utilize the results to guide policy and regulatory directions. Moreover, the study contributes to the existing body of knowledge by solidifying the framework of determinants for MASS adoption, incorporating commercial considerations alongside technical and legal factors. The results not only offer fundamental information for future research but also provide a rationale for informed decision-making in the shipbuilding and maritime industries regarding MASS adoption and operation.

Recently, Green Port project to develop an environment-friendly port is active to lead by Port of LA, Port of LB in the USA and Port of Rotterdam. While, Port of Singapore, Shanghai Port and Dubai Port are trying to be a complex Port to function as a true portal not only for freight, but also for people and information. Ports, in this era, doesn't just play a simple transportational role for passengers and freight. Ports in this 21st century, play a role as a center where passengers, freight, information and money gather and a place where freight is created from nearby supporting area. Therefore, this study intends to draw action plans for Port of Busan to grow as Complex Port in the 21st century by AHP analysis and evaluate the action plans of each field by quantitative factors (business portion in the area/specialty/synergy effect with other industry) and qualitative factors (potential for future growth/competitiveness/ capability for innovation). The evaluation result can be used as basic information to decide business priority.
