Purpose: This study was done to identify differences in work environment, work stress, turnover intention and burnout and investigate the relationship among these variables in nurses in Korean Neonatal Intensive Care Units. Method: Participants were 242 nurses working in 13 general hospitals. Burnout was measured by the Maslach Burnout Inventory (MBI), work stress with the instrument by Gu & Kim (1994), and turnover intention with the scale by Kim & Lee (2001). Size of the NICU, nurse to patient ratio, and communication satisfaction were included in work environment. Data were analyzed using Pearson correlation coefficients and multiple regression analysis with SPSS WIN program. Results: The mean score for work stress in NICU nurses was 3.43 points, for burnout, 2.72 points, and for turnover intention, 4.64 points. Burnout and turnover intention level of participants were moderate-high. Work stress, communication dissatisfaction with physician, and clinical career accounted for 33% of variance in burnout. Significant differences were found between size of NICU and staffing related to environmental characteristics in turnover intention and burnout. Conclusions: Results indicate that effective communication with coworkers and institutional support for appropriate staffing according to number of beds will help to prevent work stress, burnout, and ultimately, nurses' resignations.

Background: Low self-esteem can be an issue among health-care workers due to the hierarchical medical system. Health-care workers are also in a high pressure environment that can lead to stress and burnout. This study was conducted to estimate the proportion of health-care workers with low self-esteem, high stress, and burnout and the factors associated with these in a private hospital in Bangalore city. Methods: This cross-sectional study included a random sample of health-care workers of various cadres - doctors, nurses, nursing aides, technicians, and workers in ancillary departments such as laundry, dietary, central sterile supply department, and pharmacy, with probability proportional to size. Rosenberg Scale for Self-esteem, Cohen's Perceived Stress Scale, and Shirom-Melamed Burnout Measure were used as study tools. Results: Among the 306 health-care workers, there were high levels of low self-esteem (48.4%), stress (38.6%), and burnout (48.7%), with the lowest levels being among doctors. Those aged younger than 30 years had significantly lower self-esteem and greater stress. Conclusions: Health-care workers with low self-esteem were nearly thrice more likely to suffer high stress, Odds Ratio (OR) = 2.84 (1.36-5.92), and those who were stressed had more than three times higher chance of experiencing burnout, OR = 3.6 (2.02-6.55). Path analysis showed that low self-esteem among health-care workers had a direct effect on burnout, as well as an indirect effect through stress (mediator variable). This study indicates the need for screening and counseling for low self-esteem, stress, and burnout as part of a periodic medical examination of all cadres of health workers.

In order to analyze the sensitivity on the pulverized coal flames of the several variables, a numerical study was conducted at the gasification process. Eulerian approach is used for the gas phase, whereas lagrangian approach is used for the solid phase. Turbulence is modeled using the standard $k-{\varepsilon}$ model. The turbulent combustion incorporates eddy dissipation model. The radiation was solved using a Monte-Carlo method. One-step two-reaction model was employed for the devolatilization of Kideco coal. In pulverized flame of long liftoff height, the initial turbulent intensity seriously affects the position of flame front. The radiation heat transfer and wall heat loss ratio distort the temperature distributions along the reactor wall, but do not influence the reactor performance such as coal conversion, residence time and flame front position. The primary/secondary momentum ratio affects the position of flame front, but the coal burnout is only slightly influenced. The momentum ratio is a variable only associated with the flame stabilization such as flame front position. The addition of steam in the reactor has a detrimental effect on all the aspects, particularly reactor temperature and coal burnout.

An experimental investigation of the natural circulating boiling flow characteristic in three cases of annulus with different outer diameter, and the effect of annular gap size on the burnout behavior is presented. The experimental work was conducted for each case of test section at system pressure of $1kg/cm^2$ and inlet subcooling $0-20^{\circ}C$ in the full range of throttling ratio. As the result, the following facts were found. 1) With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$, $q_{BO}$ increases on the whole, and with the decrease of ${\Delta}T_{sub}$ and $D_{2}$, hydrodynamic instability is accelerated to happen prematually. 2)With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$ burnout characteristic shows the high velocitylow quality burnout, and with the decrease, low-velocity-high quality burnout. 3)With the decrease of A/A_{o}$, hyddrodynamic instability is singnificantly restrained and the difference of $q_{BO}$ in each $D_2$ under same condition is gradually reduced, finally converging into $1.9{\times}10^{5}kcal/m^{2}-hr$.

This study aimed to evaluate the relationship of ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life as well as burnout of kindergarten teachers for the first time in Korea. Also, it examined the odds ratio with ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life between burnout group and the comparison group through logistic regression analysis. A set of questionnaires was provided to a total of 310 participants (80 with higher burnout risk and 230 without burnout risk) from April 2015 to July 2015. All of participants were evaluated using the Korean Adult Attention Deficit Hyperactivity Disorder Scales, Beck's Depression Inventory, Beck's Anxiety Inventory, Baratte' Impulsivity Scale, Rosenberg's Self-esteem Inventory and Qulity of Life Scale. The results of this study indicated that burnout risk group is related to ADHD and anxiety and impulsivity. For the treatment of burnout in kindergarten teachers, effective evaluation and treatment of ADHD and impulsivity, as well as anxiety, seem to be necessary.

In order to provide fundamental information for developing reaction model in the practical blended coal power plants, effects of particle size and blending ratio on combustion characteristics and thermal reaction in co-firing with bituminous and sub-bituminous coals were experimentally investigated using a TGA and a laboratory-scale burner. Characteristic parameters including ignition, burnout temperature and activation energy were determined from TG and DTG combustion profiles. Distributions of flame length and mean particle temperature were investigated from the visualization of flames in slit-burner system. As coal particle size decreased and volatile matter content increased, characteristic temperatures and activation energy decreased. The ignition/burnout characteristics and activation energy are linearly influenced by a variation in particle size and blending ratio. These results indicated that the control of the coal blending ratio can improve the combustion efficiency for sub-bituminous coals and the ignition characteristics for bituminous coals.

Background: Emigration of health-care workers is a problem within global health systems which affects many countries, including Peru. Several factors have caused health-care workers to emigrate, including burnout syndrome (BS). This study aims to identify the association between BS and its dimensions with the intention of physicians and nurses to emigrate from Peru in 2014. Methods: A cross-sectional study, based on a secondary analysis of the National Survey of Health Users (ENSUSALUD - 2014) was conducted. Sampling was probabilistic, considering the 24 departments of Peru. We include the questionnaire for physicians and nurses, accounting for 5062 workers. BS was measured by the Maslach Burnout Inventory-Human Services Survey. Adjusted odds ratio (OR) was calculated using multiple logistic regression. Results: Of the study population, 44.1% were physicians, 37.7% males, and 23.1% were working in Lima. It was found that 2.8% [95% confidence interval (CI): 2.19-3.45] of health-care workers had BS. The overall prevalence of intention to emigrate among health-care workers was 7.4% (95% CI: 6.36-8.40). Association was found between BS and intention to emigrate in Peruvian health-care workers (OR = 2.15; 95% CI: 1.05-4.40). Emotional exhaustion was the BS dimension most associated with intention to emigrate (OR = 1.80; 95% CI: 1.16-2.78). Conclusion: Physicians and nurses from Peru who suffered from BS were more likely to have intention to emigrate. Policies should be established to reduce BS as a strategy to control "brain drain" from health-care workers of Peru.

Purpose: This study aimed to identify the degree of non-nursing tasks and nursing care left undone in integrated nursing care wards, and examine their relationships with nurses' burnout, job satisfaction, turnover intentions, and medical errors. Methods: A cross-sectional questionnaire survey was conducted. Data were collected using self-report questionnaires from 346 nurses working in 20 wards of seven small and medium-sized general hospitals, and analyzed using multiple regression and multiple logistic regression analysis with the SPSS WIN 25.0 program. Results: The mean score for non-nursing tasks was 7.32±1.71, and that for nursing care left undone was 4.42 ± 3.67. An increase in non-nursing tasks (β = .12, p = .021) and nursing care left undone (β = .18, p < .001) led to an increase in nurses' burnout (F = 6.26, p < .001). As nursing care left undone (β = .13, p = .018) increased, their turnover intentions also (F = 3.96, p < .001) increased, and more medical errors occurred (odds ratio 1.08, 95% confidence interval 1.02~1.15). Conclusion: Non-nursing tasks and nursing care left undone are positively associated with nurses' burnout, turnover intentions, and the occurrence of medical errors. Therefore, it is important to reduce non-nursing tasks and nursing care left undone in order to deliver high quality nursing care and in turn increase patient safety.
