This work examines whether IT managers adopt of real options such as defer, expand, contract, and abandon in order to cope with ERP risks, which include technological risk, relationship risk with SW vendors, economic risk, and security risk. We collect data of logistics firms in Seoul and its suburbs in 2018 to empirically validate the effect of risks upon the adoption of real options. The results suggest that IT managers adopt all 4 options when facing economic risk and adopt contract and abandon options only when facing security risk. Additionally, we find that IT managers prefers expand option and avoid abandon option when they think ERP compatibility is high.

In this study, AHP analysis was conducted through a survey that was organized by 9 job categories. The results show that sustainable operation risks have the highest priority level among all criteria with management interest having the highest priority level within sustainable operation risks related attributes. The most important risk attributes among stakeholder risks appeared to be asset security and cargo and conveyance security, with education and training being the most important among regulatory risks. Effective management and response to the risks from export controls on strategic trade require an understanding of supply chain security and compliance programs, effective training programs, investments for development of security systems that meet international standards. In addition, the government needs to focus on developing professionals and providing support for companies with compliance programs, working closely with businesses.

This work investigates how domestic or foreign ERP affects the relationship between risks associated ERP implementation and intention to adopt risk-mitigating options. We propose three risks such as ERP vendor risk, economic risk, and security risk should affect positively the intention to adopt the risk-mitigating options. To validate the impact of risks and to examine the difference between domestic and foreign ERP, we collected data from IT managers in small and medium sized logistics companies in South Korea using survey questionnaires. We validate the difference between domestic ERP and foreign ERP using multiple regression analyses. We find that IT managers using domestic ERP are willing to adopt risk-mitigating options for economic and security risk. In contrast, we find that IT managers using foreign ERP are willing to adopt risk-mitigating options for ERP-vendor risk. This work may provide IT managers in logistics industry a practical guideline of choosing either domestic or foreign ERP based on their risk preferences.

Program management presents unique challenges due to the complexity of interrelated projects and increased stakeholder engagement. While existing literature mainly focuses on project-level risk management, inter-project risks remain underexplored. This research addresses this gap by proposing a program risk analysis method that integrates project interdependence and stakeholder engagement. Leveraging social network analysis, the model enhances program risk management efficiency by identifying four types of inter-project risks and suggesting tailored response strategies. Through a case study of the Expo 2020 construction program, the effectiveness of the framework is demonstrated. This study enriches program and risk management literature, deepening our understanding of enhanced risk management in multi-project contexts.

Due to the steady growth of the online shopping market and contact-free consumption, the volume of parcels in South Korea continues to increase. However, there is a lack of manpower for delivery workers to handle the growing parcel volume, leading to frequent accidents related to delivery work. As a result, the government and local authorities strive to enhance last-mile logistics efficiency. As one of these measures, unmanned parcel storage lockers are installed and utilized to handle last-mile deliveries. However, the existing parcel storage involves the inconvenience of couriers having to put each parcel in each locker, and this is somewhat insufficient to relieve the workload of delivery workers. In this study, we propose parcel storage devices that use active loading technology to minimize the workload of delivery workers, extract operation risk factors to apply this system to actual sites, and establish risk reduction methods based on the ALARP concept. Through this study, we have laid the groundwork for improving the safety of the system by identifying and proposing mitigation measures for the risk factors associated with the proposed parcel storage devices utilizing active loading technology. When applied in practical settings in the future, this foundation will contribute to the development of a more efficient and secure system. By applying the ALARP concept, a systems engineering technique used in this research, to the development and maintenance of storage devices leveraging active loading technology, it is thought to make the development process more systematic and structured. Furthermore, through the risk management of the proposed system, it is anticipated that a systematic approach to quality management can be employed to minimize defects and provide a stable system. This is expected to be more useful than the existing unmanned parcel storage devices.

This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.

This study investigates the effects of privacy psychological characteristics of B2C logistics services users on their willingness to comply with their logistics companies' information protection policy. Using cognitive valence theory as a theoretical framework, this study proposes a research model to examine the relationships between users' logistics security knowledge, privacy trust, privacy risk, privacy concern, and their willingness of information protection policy compliance. To test the proposed model, we conducted a survey from actual users of logistics services and collected valid 151 samples. We analyzed the data using a structural equation modeling software. The empirical results show that logistics security knowledge positively affects privacy trust; privacy concern positively influences privacy risk; privacy trust, privacy risk, and privacy concern positively influence behavioral willingness of compliance. However, logistics security knowledge does not affect behavioral willingness of compliance. The results of the study provide several contributions to the literature of B2C logistics services domain and managerial implications to logistics services companies.

This study aims to provide a real-time information to the driver by effectively operating the advanced safety device attached to the freight vehicle, thereby minimizing insecure behavior of the driver such as speeding, rapid acceleration, sudden braking, And improve driving habits to prevent accidents and save energy. Advanced safety equipment is a device that warns the driver that the vehicle leaves the driving lane regardless of the intention of the driver and reduces the risk of traffic accidents by mitigating or avoiding collision by detecting a frontal collision during driving.The main contents of this report are as follows: In case of installing a warning device on a lane departing vehicle (excluding a light vehicle) and a lorry or special vehicle with a total weight exceeding 3.5 tonnes, the driver must continue to operate unless the driver releases the function.In addition, when the automatic emergency braking system is installed, the structure should be such that the braking device is operated automatically after warning the driver when the risk of collision with the running or stopped vehicle in the same direction is detected in front of the driving lane.

The government of South Korea has introduced various security measures in the supply chain, such as CSI (including a 24-hour rule) and AEO (Authorized Economic Operator), in compliance with global security trends and the war on terror. However, many participants in the import and export process are still unfamiliar with the purposes and functions of CSI, the 24-hour rule, and AEO. As such, considering these risks as obstacles or as factors that interfere with the import and export process, this study suggests proper management schemes, which can identify, measure and evaluate these risks.
