Abstract:
Objective To explore the effects of prolonged marine operation on the mental health status of seafarers,by using functional magnetic resonance imaging (fMRI) and through analysis of the function and activity of default mode network (DMN) of seafarers.Methods At first,the support vector machine algorithm was utilized to learn the unsupervised mental health assessment classifier,and physical checks were made for the detection of their mental health status.Several sub-health seafarers were screened out through health detection.Then,DMN activation and the distribution of DMN hubs among the sub-health seafarers were compared between the data obtained before going out to sea and after coming back from sea.Results When compared with the state of sub-health seafarers before going out to sea,the DMN activation of the seafarers after coming back from sea was significantly weakened,and the distribution of DMN hubs also changed significantly.Conclusions These changes might result in information transmission disorder,which could affect higher cognitive neural activity of the seafarers.This research could provide a valuable tool for early detection of subhealth status and mental health support of seafarers,and finally it might be beneficial for the establishment of an effective and quantitative mental health assessment system for the early warning of marine operations and the safety of seafarers.
