The magnetic entropy changes of ΔSM(T,H) around the magnetic transition temperature (TC) have been investigated by the scaling method in a two-dimensional ferromagnetic semiconductor (2D FS) CrI3 single crystal. The critical parameters based on ΔSM(T,H) have been obtained. The ΔSM(T,H) under different magnetic fields can be scaled into a single curve independent of external field and temperature. The magnetic entropy is about 3.21 J/kg K at applied magnetic field H = 4.5 T. The critical parameters n, b, and c obtained from magnetic entropy ΔSM(T,H) are about 0.62(1), 0.69(2), and 1.30(3), respectively. The value of n is close to that of the 3D Heisenberg model. The temperature dependent n at different magnetic fields scales into one universal line above TC and deviates the scaling line at low temperatures. The deviation can be attributed to the strong uniaxial anisotropy effect in CrI3. The result is helpful for understanding the origin of the magnetic phase transition in 2D FSs.

An 81-year-old man visited the emergency department (ED) with sudden onset of abdominal pain and cold sweating, which interrupted his sleep. Point-of-care ultrasound (POCUS) demonstrated the curtain sign under the scissor maneuver, along with an enhanced peritoneal stripe sign (EPSS) (Figure 1a). [Extracted from the article]

Objective: To explore the application of the Short Form of Quality of Life (SF-36) scale in the investigation of quality of life of occupational disease patients. Methods: In May 2019, SF-36 scale was used to investigate the occupational disease patients diagnosed in Hangzhou. The reliability of the scale was evaluated by Cronbach's α coefficient, and the validity of the scale was evaluated by exploratory factor analysis. Results: The Cronbach's α coefficients of PF, RP, BP, GH, VT, SF, RE and MH were 0.937, 0.977, 0.870, 0.908, 0.815, 0.701, 0.967 and 0.863 respectively, and the half reliability coefficient α=0.905. The two factor statistics representing physiological and psychological aspects were 0.870, and the approximate chi square value was 1784.337 ( P <0.01) . Compared with the national norm, the scores of each dimension of quality of life of occupational disease patients were significantly lower, and the differences were statistically significant ( P <0.01) ; Compared with the scores of each dimension of quality of life of pneumoconiosis patients, the scores of PF, RP and GH of occupational disease patients were significantly higher, and the differences were statistically significant ( P <0.05) . Conclusion: SF-36 scale has good reliability and validity in measuring the quality of life of patients with occupational diseases, which can be used to evaluate the quality of life of patients with occupational diseases.

Objective: To investigate and analyze the quality of life of occupational patients in Hangzhou and its influencing factors, so as to improve their qol. Methods: From January 2007 to June 2018, patients with diagnosed occupational diseases in Hangzhou City were randomly sampled in October 2019. The patients＇basic condition and quality of life were investigated by self-made questionnaire and SF-36, a total of 303 valid questionnaires were collected and the influencing factors were analyzed by correlation analysis and multiple linear regression. Results: The scores of physiological function, physiological function, physical pain, general health status, energy, social function, emotional function and mental health of the patients with occupational diseases in Hangzhou were lower than those of the general population in China, the differences were statistically significant ( P <0.01) . The main factors affecting the score of quality of life of occupational patients are the types of occupational diseases, the level of disability and the duration of illness, the condition of suffering from other diseases, age, educational level, whether they are entitled to Work Injury Insurance, economic income, medical security and social support, the difference was statistically significant ( P <0.05) . Conclusion: The quality of life of the patients with occupational diseases in Hangzhou City is poor, and the corresponding measures should be established to improve the qulity of life.

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.

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.
