Objective: To investigate and predict the behavioral intention and mode of the protective equipment utilization selection of the workers who used Benzene, the Theory of Planned Behavior (TPB) was applied to establish the behavioral model to enhance the theoretical foundation for long-term intervention. Methods: Questionnaires were used to survey the 707 workers, and all the behaviors of using protective equipment were investigated. Evaluate the relationships between each variable and obtain the influence affects by structural equation model. Results: The investigation showed that 38.47% of the total workers (272 cases) used whole body protection, 13.58% used partially, and 16.69% didn't use any body protection. There were significant difference between the varying degrees in the four dimensions (behavioral attitude, perceived behavior control, subjective norm, and behavioral intention) (P<0.01) . The results of structural equation model revealed that perceived behavior control was the most important influencing factor, subjective norm, positive attitude, negative attitude were the other three respects in sequence. The path co-efficient were 0.600、0.215、0.141 and 0.046 respectively. Conclusion The study show that the theory of planned behavior can effectively explain the behavioral intention and behavior of protective equipment utilization. Therefore, combining the subjective initiative of individuals with the supervision of enterprises, In order to effectively enhance the protective equipment utilization of benzene workers.

Objective: To understand the quality of life and influencing factors of patients with pneumoconiosis, and to provide a basis for formulating targeted improvement strategies to improve the quality of life. Methods: From April to December 2018, Questionnaire survey was conducted on patients with pneumoconiosis that diagnosed in Hangzhou Hospital for the Prevention and Treatment of Occupational Disease, using self-made questionnaire and SF-36.237 valid questionnaires were used to investigate the basic conditions, health services, social assistance and quality of life of patients, and analyze the influencing factors of quality of life. Results: Hangzhou city's some pneumoconiosis patients were mostly with monthly income <3000 yuan (72.6%, 172/237) ; more patients with medical expenses of 8000 to 25000 yuan per year (60.3%, 143/237) ; The proportion of patients receiving medical assistance and work-related injury insurance was low, at 2.1% (5/237) and 23.8% (54/227) respectively. The scores of Pneumoconiosis patients in PhysicalFunction (PF) , Role-Physical (RP) , Bodily Pain (BP) , General Health (GH) , Vitality (VT) , Social Function (SF) , Role-Emotional (RE) and Mental Health (MH) were lower than the national norm (P<0.05) . The scores from high to low were BP, SF, MH, PF, VT, RE, RP and GH. There were significant differences in the quality of life scores of pneumoconiosis patients with different ages, work types, education levels and monthly income (P<0.05) . Conclusion The quality of life of some patients with pneumoconiosis in Hangzhou is lower than that of the general population. Age, work types, and monthly income are factors influencing quality of life.
