The purpose of this study is to analyze the relationship between logistics safety climate, logistics safety behavior, and logistics safety performance and the mediating effects of safety knowledge and safety motivation, and to suggest its strategic implications for the improvement of the logistics safety performance. Based on previous researches related to logistics safety, safety climate, safety knowledge, safety motivation, safety behavior and safety performance, research models and hypotheses were set up and questionnaires were conducted. For the hypothesis test, reliability analysis and validity analysis, confirmatory factor analysis, structural equation model analysis, and bootstrapping were applied. As a result of the empirical analysis, the logistics safety climate had a significant positive effect on logistics safety knowledge, logistics safety motivation, and logistics safety behavior, whereas logistics safety knowledge and logistics safety motivation had a meaningful positive effect on logistics safety behavior. Further, logistics safety behavior was found to have a significant positive effect on logistics safety performance. Safety behavior had a significant mediating effect, but safety knowledge and safety motivation did not. However, logistics safety climate, logistics safety knowledge, and logistics safety motivation did not have a significant effect on logistics safety performance.

Purpose: This study aims to contribute to the research flow on the relationship between win-win supportive collaboration and safety, while noting that win-win supportive collaboration affects corporate safety-related factors such as climate, safety prevention, and behavior from the perspective of domestic small and medium-sized logistics companies that have signed contracts with large logistics companies, Methods: Based on responses from 147 small and medium-sized logistics companies, structural equation modeling is performed to examine the relationship among the factors such as supportive collaboration, safety climate, safety prevention, safety behavior. Results: Study results are as follows. Supportive collaboration of large logistics companies influence the formation of a safety climate and safety behavior within logistics SMEs positively. In addition, safety prevention and safety behavior are affected by safety climate in a positive way. Conclusion: Win-Win supportive collaboration is a driving force behind safety management practices in the supply chain leading to safety management performance, so it is necessary to consider it for the growth of the sustainable supply chain.

A safe working environment is an important and crucial factor in the operation of a firm, and is also essential for logistics companies in supply chain management. This study confirmed that the safety climate and safety prevention activities have a positive relationship with safety behavior from the perspective of domestic small and medium-sized logistics companies that continue their business relationships by signing contracts with large logistics companies. In addition, the moderating role of regulatory uncertainty and competition uncertainty in the previous positive relationship was empirically examined.

Global interests in RFID are increased and Korean government and companies make an active effort to propagate and spread RFID. Due to the overwhelming advantages of RFID system in comparison with existing bar code system, ripple effects on logistics sector among the utilizing fields of RFID technology are expected to be great, but application of RFID system is lowly progressed unlike the expectation of several experts. Therefore, this research extracts precedent studies on theoretical background, applying fields, promotion condition and domestic/foreign parts of RFID system, factors for operating domestic RFID system and effects and considers the effects of RFID's external variables on easiness and effectiveness of TAM. It confirms the relations of RFID applying effects for companies applying and utilizing RFID and verifies the relations among the effects for application of RFID system, accepting intention of RFID system and applying effects. Based on the results of analysis, it should play a role of good guide for all of companies and institution who will introduce RFID system to all of Korean logistics fields, make policies and systems which promote RFID acceptance nationally and socially and play a role of guide making confident climate for RFID technolog

In line with the advanced wireless communication technology, M2M (Machine-to-Machine) communication has drawn attention in industry. M2M communication features are installed and operated in the fields where human accessibility is highly limited such as disaster, safety, construction, health and welfare, climate, environment, logistics, culture, defense, medical care, agriculture and stockbreeding. In M2M communication, machine replaces people for automatic communication and countermeasures as part of unmanned information management and machine operation. Wireless M2M inter-device communication is likely to be exposed to intruders' attacks, causing security issues, which warrants proper security measures including cross-authentication of whether devices are legitimate. Therefore, research on multiple security protocols has been conducted. The present study applied SessionKey, HashFunction and Nonce to address security issues in M2M communication and proposed a safe protocol with reinforced security properties. Notably, unlike most previous studies arguing for the security of certain protocols based on mathematical theorem proving, the present study used the formal verification with Casper/FDR to prove the safety of the proposed protocol. In short, the proposed protocol was found to be safe and secure.

The International Maritime Organization (IMO) has been seeking measures to prevent climate change caused by shipping and actively discussing the initial strategy of reducing ship greenhouse gas emissions adopted in 2018. Member states are proposing various reduction measures in the IMO's 5th International Working Group on the Reduction of Greenhouse-gas emissions. However, each member country's method of measuring impact assessment differs, making it impossible to objectively compare impact assessment by country. As such, various measures have been proposed by each country to reduce greenhouse gas emissions, and it is necessary to determine a standard impact assessment measurement method that can be applied to all countries before 2023, when IMO's greenhouse gas reduction strategy is implemented. Therefore, this study seeks to develop detailed guidelines for impact assessment to objectively compare the impact assessment results of ships' greenhouse gas reduction measures. Drawing detailed guidelines that can compare the effectiveness of each country's reduction strategies will enable the IMO leading marine environment GHG reduction.
