Background: As the number of COVID-19 patients rises, there has been a notable increase in the workload for nurses. However, medium-sized hospitals lacked standardized protocols or consistent approaches to address the specific working conditions of nurses. Furthermore, concerns about patient care have heightened as the issue of nursing shortages coincides with the expansion of the comprehensive nursing care services project.

Aims: This study constructed and tested a structural equation model on clinical nurses' emotional labor, job satisfaction, and job performance based on Grandey's emotion regulation model.

Design: We performed a correlational study to predict the relationship between the following variables: emotional labor (surface and deep acting), job satisfaction, job performance, self-efficacy, emotional intelligence, display rules, job autonomy, social support, and job stress.

Methods: Our hypothetical model was based on Grandey's emotional regulation model and on a literature review of emotional labor, job satisfaction, and job performance.

This study examined the health promotion model (HPM) as a framework for assessing perceptions and health-related behaviors related to cardiovascular disease (CVD) risk among blue-collar workers. This was done with the aim of providing time-sensitive educational and training materials for workers while on the job or functioning in their communities. The revised HPM was evaluated in the above context using specific criteria developed by Chinn and Kramer (2008) and scoping literature review.

(1) Background: This study aims to investigate the impact of emotional labor and workplace violence on sleep disturbance, depression, and health status in workers. (2) Methods: Data from 34,742 participants of the 2011-2014 Korean Working Conditions Survey were included in this study. We compared the incidence of sleep disturbance, depression, and health status according to emotional labor and workplace violence and used logistic regression to analyze factors that affect health status.

Contextual factors are associated with risks of cardiovascular disease (CVD) perceived by personnel employed in small-medium-sized workplaces. In an ecological model, data collection and analysis were undertaken, stratified by intrapersonal, interpersonal, and organizational contexts of blue-collar workers. Data were collected in face-to-face ( = 36) and focus group ( = 4) interviews and subjected to qualitative content analysis, to generate three main themes, 10 generic categories and 18 sub-categories.

This study developed and evaluated a health management program based on the participant-centered concept of action research to reduce cardiovascular disease (CVD) risk factors among blue collar workers. Data from structured questionnaires completed by 32 workers in a small-to-medium sized workplace from September 2015 to October 2016 as well as participants' anthropometrical (weight and waist) and biological (blood pressure, glucose, total cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) cholesterol) data were analyzed using paired t-test and Fisher's exact test. To examine the longitudinal effect of the intervention, survival analysis and linear mixed model (LMM) were used.

While seeking to achieve high performances of a bulk piezoelectric acceleration sensor, we investigated the behavior of the design variables of the sensor components and optimized the sensor design using a numerical simulation based on piezoelectric analysis and metamodeling. The optimized results demonstrated that there was an exponential dependency in the trade-off relation between two performance indicators, the electric voltage and the resonant frequency, as induced by the design characteristics of the sensor. Among the design variables, a decrease in the base height and epoxy thickness and an increase in the piezo element's inner diameter had a positive effect on two performances, while the head dimensions (diameter and height) exhibited the opposite effect on them.
