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.

Following the accident at Fukushima, the true impact of multi-unit accidents came to light. Accordingly, research related to multi-unit accident effect analysis, risk evaluation, and accident prevention/prevention technology has been conducted. Specific examples are mobile/fixed equipment such as multi-barrier accident coping strategy (MACST) and diverse and flexible coping strategies (FLEX), which have been introduced and installed in multi-units for preventing and mitigating multi-unit accidents. These strategies are useful for enhancing the safety of nuclear power plants (NPPs); however, a more efficient strategy is required in terms of the costs of physical and human resources. To effectively and efficiently mitigate an increase in multi-unit accidents, it is necessary to not only to utilize mobile/fixed equipment but to also use crosstie options with resources that already exist at NPPs. Therefore, we analyzed the current international and domestic status of crosstie systems technology and propose a method to evaluate feasibility alongside risk based on a multi-unit probabilistic safety assessment (PSA). To analyze the international and domestic status of crosstie systems technology, actual cases and related research were studied, and a list of potential crosstie safety resources was derived. Additionally, a case study was performed on crosstie cases of two systems within the assumed six units on-site under a multi-unit accident, and a multi-unit PSA-based risk evaluation method is proposed.
