Pilots are indispensable and central to the aviation industry, with the relevance of their psychological stress and resultant human errors increasingly recognized as critical. This study aims to meticulously explore the interrelations between psychological stressors and associated factors among helicopter pilots, assessing the consequent effects on potential accidents and incidents. The study comprised active pilots from domestic helicopter airlines, with data collated through both focus group interviews (FGI) and comprehensive surveys. These data were subsequently analyzed using SPSS and AMOS for structural equation modeling. The results reveal that heightened psychological stress in helicopter pilots correlates with an increased incidence of human errors, which in turn, elevates the likelihood of potential safety incidents. Based on these findings, it is proposed that interventions designed to mitigate psychological stress among pilots could significantly reduce human errors and enhance overall aviation safety. This research provides crucial insights into specific ways to improve the operational conditions for helicopter pilots and strengthen the safety protocols within the aviation industry.

This study aimed to explore the causal relationship between an infant-mother's job satisfaction, psychological features, parenting stress and marital conflict through structural equation modeling. Specifically, we tried to identify influences of an infant-mother's job satisfaction on parenting stress and marital conflict and demonstrated how psychological features (self-efficacy, self-esteem, and depression) were mediated by these influences by using a sample of 444 Korean infant-mothers with jobs from the 3rd year of Korean Children and Youth Panel Survey with AMOS 20.0. First, the results demonstrated that job satisfaction of an infant-mother positively related to their self-efficacy and self-esteem whereas negatively related to depression among psychological features. Furthermore, job satisfaction of an infant-mother showed negative relationships with parenting stress and marital conflict. Second, an infant-mother's job satisfaction did predict marital conflict, but not parenting stress. However, these job satisfactions were mediated by an infant-mother's psychological factors. Findings were discussed with regard to the relationship between an infant-mother's job satisfaction, parenting stress, and martial conflict in the family counseling implications.
