ABSTRACT
Improving the well-being of the employees is the inevitable choice to improve corporate performance and competitive advantage and the social responsibility that enterprises must undertake. Based on the job demands-resources model, this study introduces perceived organizational support and work stress as the mediator and trade union practice as the moderator to explore the double-edged sword effect of a high-performance work system (HPWS) on the well-being of the employee. Taking 243 employees from Jiangsu, Zhejiang, and Anhui as samples, we found that HPWS positively affects the well-being of the employee through perceived organizational support and negatively affects the well-being of the employee through work stress. Union practices can significantly reduce the positive effect of HPWS on work stress and further weaken the negative effect of HPWS on the well-being of the employee through work stress. The results of this study provide a new way to explain the impact of the HPWS on the well-being of the employees and find that union practice can weaken the negative effects of HPWS. This study provides a new thinking direction for improving the well-being of employees in enterprises.
ABSTRACT
Objective:To study the feasibility of using bedside ultrasound in evaluating gastric residual volume in critical ill patients with enteral nutrition support.Methods:From May 2019 to August 2019, 60 patients were selected to receive enteral nutrition via gastric tube in ICU of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. Patients were divided into the experimental group and the control group according to the odd and even number of beds, 30 patients in the experimental group with odd number of beds and 30 patients in the control group with even number of beds. Gastric residual volume was evaluated at 0, 4, 8, 12, 16, 20, 24 h of enteral nutrition. In the experimental group, the gastric residual volume was evaluated by bedside ultrasound and syringe suction at each time point. In the control group, only bedside ultrasound was used to evaluate gastric residual volume. The results of operation time, monitoring results at different time points, diarrhea and the utilization rate of gastrointestinal motility drugs target feeding time, vomiting, were compared between the two groups.Results:There was no statistical difference between the gastric residual amount monitored by ultrasound and the gastric residual amount monitored by suction ( P>0.05). The operating time of bedside ultrasound monitoring was (62.40 ± 4.00) s, the operating time of suction monitoring was (78.39 ± 12.15) s, and the operating time of bedside ultrasound monitoring was less than that of suction ( t value was 6.633, P<0.01). There was no significant difference in the rate of vomiting, diarrhea and gastrointestinal motility drugs between the two groups( P>0.05). The time to reach the target feeding amount in the control group was (3.04 ± 0.31) d, and the time to reach the target feeding amount in the experimental group was (4.19 ± 0.33) d. The time to reach the target feeding amount in the control group was less than that in the experimental group ( t value was 13.42, P<0.01). Conclusions:Bedside ultrasound can be used to evaluate the residual gastric volume of enteral nutrition support patients, guide the implementation of enteral nutrition, shorten the operation time, reduce the workload of nurses, and avoid the contamination of enteral nutrition preparation.
