Job stress factors are factors that induce biological, psychological, and behavioral responses in individuals when they encounter mental and physical stimuli in the workplace. According to occupational safety and health standards, employers are responsible for the health consequences of job stress when workers engage in activities that result in high levels of physical fatigue and mental stress. Such activities include long working hours, shift work (including night shifts), driving vehicles, and operating precision machinery. Therefore, precautionary measures should be implemented. Following the COVID-19 epidemic, the logistics industry in Korea has experienced rapid growth owing to the shift from offline to online platforms facilitated by advanced digital infrastructure. Consequently, this study conducted a survey to analyze job stress factors among delivery workers. The survey utilized a Korean job stress factor assessment tool comprising 43 items and analyzed job stress factors considering the work characteristics of the courier business field obtained from responses provided by 421 courier workers nationwide. The survey analysis revealed that the physical environment, job demands, and job autonomy exhibited higher stress indices among Korean workers. Furthermore, the younger the age, the higher the stress on job demands, whereas the higher the age, the higher the stress on relationship conflict, job instability, and workplace culture. In addition, daytime delivery work was associated with higher stress levels in job demands and job instability compared with nighttime delivery work. These findings can serve as foundational data for reducing and preventing job stress among courier workers, whose workload has increased owing to the growth of the logistics industry.

In a global environment, airlines are striving to secure competitiveness and generate profits through customer satisfaction. The first thing to do in order to provide services to customers is the safety of the aircraft, and the basis for realizing safety is the continuous maintenance of maintenance quality. The degree of development of aviation technology is progressing unimaginably fast, but the overall environment of aviation mechanics working at the front line to maintain maintenance quality remains largely unchanged. This study aims to identify the level of education and training provided to aircraft maintenance engineers and safety culture, and to examine the effect of self-esteem on maintenance quality. Previous studies have been conducted on maintenance engineers' education and training, organizational performance, and job stress, but there has been a lack of studies on maintenance quality. Therefore, this study aims to identify the relationship between variables affecting maintenance quality and to suggest implications for improving maintenance quality through empirical analysis.

EDI is basically the concept of computer-to-computer exchange of messages relating to various types of activities or business areas, such as banking, trade, medicine, publishing, etc. Therefore, security, reliability and special functionality will be implicit requirements of EDI systems. We will design access control model to content security of these requirements. Access controls in information systems are responsible for ensuring that all direct access to the entities occur exclusively according to the access modes and rules fixed by security policies. On this paper, security policies for access control model are presented from the viewpoints of identity-based, rule-based, role-based policy. We give a design of access control model for secure EDI service based on the derived access control rules and operations to enforce the defined security policies. The proposed access control model provides integrity, confidentiality and a flow control of EDI messages.

This paper presents an human reliability assessment(HRA) for a installation task of the temporary power cable in construction fields. HRA is evolved to ensure that the workers could reliably perform critical tasks such as a process of the temporary power cable. Human errors are extremely commonplace, with almost everyone committing at least some errors every day. The considerable parts of electric shock accidents in the construction field are caused by a series of human errors. Therefore it is required to analyze the human errors contained in the task causing electric shock event, the event tree analysis(ETA) is adopted in this paper, and particularly human reliability was estimated for a installation task of the temporary power cables. It was assumed that the error probabilities of the human actions may be obtained using the technique for human error rate prediction(THERP). The results show that the predominant task on reliability in the cable installation tasks is check-out tasks and the probability causing electric shock by human errors was calculated as $1.0\times10^{-9}$.

This paper has studied the effect of airline staff's perception on both aviation safety and aviation security to their organizational effectiveness. Airline staff's perception on aviation safety is different from that on aviation security due to organizational difference in an airline. Through an empirical analysis, it was analyzed the effect of such perceptional difference on airline's organizational effectiveness. According to the analysis, it was found the perception of aviation safety has a significant positive effect on organizational effectiveness. Airline staff believed the safety is a core value of an airline and emphasizing the safety never impeded the airline's operation including service quality. Secondly, it was proven the perception on abiding by aviation security rules had a significant negative effect on organizational effectiveness. However, emphasizing aviation security had a very significant positive contribution on airline's philosophy of aviation safety. Following the research results, it was suggested an airline look for improving the process and regulations to deal with aviation security in the organization.
