Based on data from the CLDS 2018, this paper analyzed the effects of hygienic and motivational factors on job burnout, as well as the mediating role of the sense of effort-reward and the moderating role of job satisfaction, with 713 employees within the system as the research subjects. The results found that: hygienic factors negatively affect job burnout, and motivational factors have no direct correlation with job burnout. The sense of effort-reward plays a partial mediating role between hygienic factors and job burnout, and a masking role between motivational factors and job burnout. Job satisfaction moderates the relationship between the sense of effort-reward and job burnout. The findings provide a reference for alleviating job burnout and improving the work mindset of employees with the system.展开更多

After that, normalized histograms and cumulative histograms for ROI and region of background （ROB） are calculated. The mapping functions of the corresponding regions are derived from reference image to distorted image through the nearest cumulative histogram matching method, so that color correction can be finally achieved. Experimental results show that benefitting from the separate treatment to ROI and ROB, the proposed color correction method could avoid error propagation between the two different regions, which achieves good color correction result in comparison with other correction methods.展开更多
