The door systems in urban railway vehicles, through heavy maintenance checks by six years, 75 parts for 34 part types in 75 units have to be replaced periodically, and the remaining 68 parts for 40 part types to be replaced occasionally based on the necessity. Even though this process makes the door systems almost to be initial status, the systems have complicated mixes of components with new parts and used and then have different property from the original ones. This study suggested a burn-in test as a subsidiary tool to improve the reliability of urban railway vehicles, and suitable for testing conditions and the proposed new target value.

Purpose : The purpose of this study was to identify factors influencing the professional self-concept of nurses working in intensive care units (ICUs). Methods : Data were collected from July 1 to August 15, 2014. The subjects were 206 ICU nurses working in four university hospitals in B and U cities, Korea. Their professional self-concept was measured using Arthur's Scale revised by Yoon (2012), and professional quality of life (QOL) was measured using Pro QOL Korean Ver. 5 developed by Stamm (2010). Data were analyzed with SPSS Ver. 18, using a t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results : Professional self-concept was significantly correlated with compassion satisfaction (r=.61, p<.001), and burn out (r=-.57, p<.001). The factors influencing professional self-concept were compassion satisfaction (${\beta}=.46$, p<.001), burn out (${\beta}=-.27$, p<.001), and education level (${\beta}=.14$, p =.014). The explanatory power of this model was 46.5%. Conclusion : The results suggest that the influencing factors found in this study should be considered when planning nursing intervention programs for improving the professional self-concept of ICU nurses.

Wetlands are a transitional zone between aquatic and terrestrial ecosystems, and a habit for the various biospheres. The main purpose of this study is to suggest a new technique that establishes the management districts of inland wetlands. To establish management districts of sub-watershed units, this study used the BurnDEM techniques. The management district resulted form this study are assessed its effectivity using an overlap of inland wetland map and sub-watershed maps classified by 18 sub-watershed. The result of this study could be applied to build a national inland wetland database.

This study is a survey and research attempted to seek the ways of effective human resource management and improving the quality of nursing - targeting the nurses working for the general hospitals - by analyzing the impact of job satisfaction and job stress factors on exhaustion and turnover intentions, so as to find the nurses' turnover factors and remove those factors in advance. Although we cannot raise job satisfaction to the level we are satisfied by monetary compensation, i.e. salary alone, but as seen in this study, it is worth considering such ways as the subjects with high salaries showed relatively higher job satisfaction. Finally, in order to prevent the turnover of the competent nursing staff at an early stage, active systematic supplements and efforts are required; it is also necessary to provide constant job training, by taking into account of the specificity of nursing units and to secure and place adequate nursing staff, and to establish fair and objective promotion criteria.

Purpose : This study aims to identify job stress, emotional intelligence, and exhaustion of the nurses in comprehensive nursing service units and then verify the moderating and mediating effects of emotional intelligence on the relationship between job stress and exhaustion. Methods : Participants are 118 nurses working in two general hospitals. The collected data are analyzed using the SPSS WIN 27.0 and AMOS 18.0 programs by assessing frequency and percentage, mean and standard deviation, independent t-test and one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis and bootstrapping. Results : Exhaustion has a statistically significant positive correlation with job stress (r=.40, p <.001) and a statistically significant negative correlation with emotional intelligence (r=-.26, p =.004). A partial mediating effect of emotional intelligence is found between job stress and exhaustion, however, there is no moderating effect. Conclusion : It is expected that to reduce the exhaustion of nurses in comprehensive nursing service units, it is necessary to assess job stress and emotional intelligence, and strengthen emotional intelligence along with job stress intervention.

Purpose : Multidrug-resistant Acinetobacter baumannii (A. baumannii) is recognized to be the most difficult pathogen to control and treat in pediatric burn centers. We analyzed the antibiotic susceptibility pattern of A. baumannii in our pediatric burn intensive care unit during the past 7 years. Methods : We retrospectively evaluated 56 patients (105 samples) under the age 15 years and who were infected with A. baumannii between January 1999 and December 2005. Results : Fot the 56 patients, the ratio of males to females was 1.15:1 and the median age was 48.3 months. The sites of 105 isolates were wounds (65%), sputum (20%), blood (6 %), cutdown tips (5%), endo-tip tubes (2%) and urine (2%). A. baumannii presented yearround. The annual antimicrobial resistance rate increased and the multidrug resistant rate for two or more antibiotics was 93.33%. For 3 patients in whom resistance emerged, the interval period between the susceptible and resistant strains after antibiotic use was a mean of 10 days. The A. baumannii isolated from blood were all multi-drug resistant pathogens. Conclusion : Multidrug resistance of A. baumannii is increasing. Strict infection control guidelines and active surveillance are needed for the prevention and treatment of A. baumannii in hospitals.

Purpose: The purpose of this study was to investigate the influence of communication competence and burnout on nursing performance in intensive care units (ICU). Method: The participants were 209 nurses from four university hospitals. Measurements included a socio-demographic and job related survey, communication competence inventory, the Maslach burnout inventory and a nursing performance scale. Data were collected from February 6 to 24, 2012, with a self-report questionnaire. The statistical analyses were performed with SPSS 18.0 software. Results: The mean scores for communication competence, burnout and nursing performance were 50.49, 84.72, and 62.18, respectively. Communication competence (r=.44, p<.001) and burn out (r=-.32, p<.001) were significantly correlated with nursing performance. In the multiple linear regression, factors influencing nursing performance were communication competence, age and burnout. These variables explained about 46% of the total variance of nursing performance. Communication competence (${\beta}$=.34, p<.001) was the most influential factor. Conclusion: Nurses' poor communication skills and burnout can influence the occurrences of medical errors in ICU nursing performance. The results suggest that good communication and burnout resolution skills programs should be implemented to improve nursing performance efficiency.

Psychiatric disorders are quite common in surgical patients. However, surgeons are less likely to refer patients to psychiatrists than other physicians, who also have a tendency to under-recognize psychiatric disorders among their patients. Therefore, a large proportion of psychopathology in surgical patients is either undiagnosed or misdiagnosed and not optimally treated, if treated at all. This column focuses on common psychiatric issues that generally arise in surgical patients and reviews psychiatric issues specific to specialized surgical settings and patients (eg, burn units, obesity surgery).

The intensive care unit (ICU) is the most common place to die. Also, ethical conflicts among stakeholders occur frequently in the ICU. Thus, ICU clinicians should be competent in all aspects for ethical decision-making. Major sources of conflicts are behavioral issues, such as verbal abuse or poor communication between physicians and nurses, and end-of-life care issues including a lack of respect for the patient's autonomy. The ethical conflicts are significantly associated with the job strain and burn-out syndrome of healthcare workers, and consequently, may threaten the quality of care. To improve the quality of care, handling ethical conflicts properly is emerging as a vital and more comprehensive area. The ICU physicians themselves need to be more sensitive to behavioral conflicts and enable shared decision making in end-of-life care. At the same time, the institutions and administrators should develop their processes to find and resolve common ethical problems in their ICUs.

Transmutation characteristics of minor actinides in a transmutation reactor based on a Low Aspect Ratio (LAR) tokamak are investigated. One-dimensional neutron transport and burn-up calculation coupled with the tokamak systems analysis were performed to find the optimal system parameters. The dependence of the transmutation characteristics such as neutron multiplication factor, produced power and transmutation rate on an aspect ratio A in the range of 1.5 to 2.0 was investigated. By adding Pu239 in the transmutation blanket as a neutron multiplication material, it was shown that the one unit of the transmutation reactor based on the LAR tokamak producing fusion power of 150 MWth can destroy the minor actinides contained in the spent fuels produced from more than 19 units of l GWe PWRs with production of the power being in the range of 0.9 - 3.4 GWth.
