Since nursing is carried out in a relationship between nurses and nursing subjects in a social context, the social problem solving ability of nursing college students is very important. The purpose of this study was to identify impact of self-leadership, caring ability and self-efficacy on social problem solving ability in nursing student's. The subjects of this study were 203 nursing college students from a university. Data was analyzed using Pearson correlation and multiple regression. The result of multiple regression indicate that caring ability(${\beta}=0.39$, p<.001) self-efficacy(${\beta}=0.28$, p<.001), self-leadership(${\beta}=0.23$, p<.001) were the most consistent predictors of social problem solving ability and explained 53.0%. It is suggested to establish an autonomy-based program and feedback system and to develop a convergence education program to balance cognitive and emotional aspects.

Objectives: This study aimed to verify the relations of COVID-19 infection-related knowledge, dental infection control performance, and psychosocial health of dental hygienists. Methods: From the data was analyzed through the frequency analysis, t-test, one way ANOVA, and pearson's correlation analysis with a total of 198 dental hygienists using SPSS Statistics 21.0. Results: The correct answer rate for knowledge about COVID-19 was higher with a bachelor's degree or higher. Thus, when the level of education was higher, the performance was also high (p<0.01). COVID-19 infection control performance was highly shown in case of high age (4.43) (p<0.05) and the married (4.42) (p<0.01). Infection control performance was high when they had an educational experience of COVID-19 infection control (4.46), and when the infection control guidebooks were equipped in their workplaces (p<0.001). Degree of psychosocial health of research subjects was shown in the order of potential stress (60.6%), high-risk stress (23.7%), and healthy (15.7%). Infection control performance was higher, the psychosocial health was healthy. Conclusions: For the response to COVID-19 infectious disease and the preparation for mutated viruses and new infectious diseases in the future, it would be necessary to establish the concrete measures for establishing the strict infection control system for dental clinics and also enhancing the psychosocial health of dental hygienists.

Background: Pembrolizumab, an anti-cancer drug, is known to increase the activity of the immune system, leading to side effects called immune-related adverse events (irAE), including type 1 diabetes. This study analyzed the correlation between blood glucose level and pembrolizumab administration and investigated the covariates that affect those changes in cancer treatment. Methods: The information of 133 adult cancer patients was obtained from the electronic medical record (EMR) to identify the changes in random blood glucose (RBG) levels during the pembrolizumab treatment. Subjects were classified into subgroups according to their baseline RBG level, history of diabetes, and the use of steroids, and linear regression analysis was conducted. In addition, a secondary analysis was performed within the group of subjects having a strong correlation to glycemic change, which was based on the Pearson correlation coefficient being less than -0.7 or greater than +0.7. Univariate and multivariate logistic regressions were conducted to identify the risk factors to glycemic increase. Results: The RBG level tended to descend without significant differences in total patients during the administration period of pembrolizumab. Despite the insignificance, the logistic regression analysis presents that the odds ratios of baseline RBG less than 130 mg/dL, prophylactic steroid use, and higher dose of pembrolizumab per cycle (mg/kg/cycle) were greater than 1. Conclusions: Prophylactic administration of steroids and a higher dose of pembrolizumab per cycle may increase the blood glucose level as irAE in cancer patients with a strong tendency to glycemic change.

Objective : The purpose of this study is to investigate the relationship among the degree of symptoms of posttraumatic stress disorder (PTSD) and social support, stress coping strategies, and self-esteem in patients with PTSD. Methods : A total of 48 patients meeting DSM-5 criteria for PTSD and 48 normal controls were recruited for participation in this study. We evaluated subjects using the Clinician-Administered PTSD Scale (CAPS), Hamilton Anxiety Scale (HAM-A), Hamilton Depression Scale (HAM-D), Rosenberg Self-Esteem Scale (RSES), Multidimensional Scale of Perceived Social Support (MSPSS) and The Ways of Stress Coping Questionnaire (SCQ). We analyzed data using an independent t-test and Pearson's correlation analysis. Results : In PTSD patients, total CAPS scores showed a significant positive correlation with HAM-A and HAM-D scores and a significant negative correlation with MSPSS scores. RSES scores showed a significant positive correlation with MSPSS and SCQ scores. MSPSS scores showed a significant negative correlation with PTSD avoidance and numbing and HAM-D scores. SCQ scores showed a significant negative correlation with PTSD avoidance and numbing. Conclusion : These results revealed that the better the stress coping strategies and social support, the lower the degree of symptoms in patients with PTSD. In addition, it was found that the higher the social support and self-esteem, the lower the degree of depression and anxiety. Therefore, in the treatment process, it seems important to identify and correct the self-esteem, social support system, and stress coping strategies of patients with PTSD.

Electronic health records (EHRs) enable us to use and re-use electronic data for various multiple purposes, such as public reporting, quality improvement, and patient outcomes research. Current hospital-acquired pressure injury (HAPI) risk assessment instruments have not been specifically developed for intensive care unit (ICU) patients and showed false positive rates in this specific populations. Previous research studies report a number of risk factors; however, it is still not clear what factors influence ICU HAPI in this population. As part of a larger research study, we performed an exploratory analysis by using a large electronic health record data. The aims of this study were to compare characteristics of patients who developed HAPIs during their ICU stay with those who did not, and to determine whether the two groups were different in the aspects of length of ICU stay, discharge disposition, and discharge destinations. We conducted chi-square test and t-test for group comparison. Association was examined by using bivariate analyses. Pearson correlation coefficients were used to examine correlation between LOS and number of medications. Our findings suggest a number of consistent and potentially modifiable risk factors, such as sedation, feeding tubes, and the number of medications administered. The mortality of the HAPI group was significantly higher than the non-HAPI group in our data. Discharge disposition was significantly different between the groups. 67% of the HAPI group transferred to intermediate or long-term care hospitals whereas 57.7% of the non-HAPI group went home after discharge. Awareness of these risk factors can lead to clinical interventions that can be preventative in the ICU setting.

This study investigated the relationship between heat-related illnesses obtained from healthcare big data and daily maximum temperature observed in seven metropolitan cities in summer during 2013~2015. We found a statistically significant positive correlation (r = 0.4~0.6) between daily maximum temperature and number of the heat-related patients from Pearson's correlation analyses. A time lag effect was not observed. Relative Risk (RR) analysis using the Generalized Additive Model (GAM) showed that the RR of heat-related illness increased with increasing threshold temperature (maximum RR = 1.21). A comparison of the RRs of the seven cities, showed that the values were significantly different by geographical location of the city and had different variations for different threshold temperatures. The RRs for elderly people were clearly higher than those for the all-age group. Especially, a maximum value of 1.83 was calculated at the threshold temperature of $35^{\circ}C$ in Seoul. In addition, relatively higher RRs were found for inland cities (Seoul, Gwangju, Daegu, and Daejeon), which had a high frequency of heat waves. These results demonstrate the significant risk of heat-related illness associated with increasing daily maximum temperature and the difference in adaptation ability to heat wave for each city, which could help improve the heat wave advisory and warning system.

This study analyzed the relationship of turnover intention of clinical nurses with self-leadership, job involvement, and empowerment. The participants were 173 clinical nurses working in D city and K province in Korea. Data analysis consisted of independent t-tests, ANOVA, Scheffe's tests, Pearson's correlations, and stepwise multiple regression conducted using SPSS WIN 21.0. There was a significant correlation between self-leadership, job involvement, empowerment and turnover intention. Factors affecting turnover intention were total clinical career, position, salary, marital status and job involvement. Total clinical career was the most influential factor, with an explanatory power of 28.7%. Based on the results, it is necessary to reduce turnover intention of nurses through the development of educational programs to increase job involvement and reorganization of the hospital organization system to manage nursing manpower resources efficiently.

Purpose : The purpose of this study was to examine the correlation between static and dynamic balance according to the virtual reality-based squat and conventional squat exercise. Methods : Twenty four participants were randomly assigned to the virtual reality-based squat (VRS) group (n=12) or conventional squat (CS) group (n=12). The static balance (C90 area, C90 angle, trace length, sway average velocity) and dynamic balance (forward, rearward, leftward, rightward) were measured using a force plate by BT4. The VRS group used the virtual reality system during 4 weeks, while the CS group underwent classical squat training. Independent t-test was used to test the homogeneity of the general characteristics of the subjects. The collected data was analyzed using the paired t-test for static and dynamic balance comparisons before and after exercise in both groups and Pearson's test for the correlation between static and dynamic balance according to the measured time. The significance level was set to 0.05. Results : There was no significant correlation between group and static and dynamic balance related variables (p>.05). There was a significant correlation between measurement time and static and dynamic balance related variables (p<.05). According to the measurement time, the static balance parameter C90 area in the VRS group after exercise was significantly decreased (p<.05). The values of forward, leftward and rightward in the VRS group were significantly increased after exercise (p<.05). Conclusion : It is suggested that 20 normal healthy adult men and women who have normal balance ability can improve their ability to control their posture by improving the balance ability when applying virtual reality-based squat exercise.

Objectives: The purpose of this study was to examine the perception of dental hospital accreditation and the awareness and practice of infection control in dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygienists working at dental hospitals in Gwangju Jeonnam and analyzed from October 24, 2016 to September 22, 2017. Data were analyzed with the independent t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis using the Statistical Package for the Social Sciences software, version 21.0. Results: Compared to non-accredited dental hospitals, all three variables were high for accredited dental hospitals. In accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness (r=0.407) and practice (r=0.533) of infection control, and awareness of infection control correlated to its practice (r=0.725). In non-accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness of infection control (r=0.239), and awareness of infection control correlated to its practice (r=0.481). Accredited dental hospitals showed healthcare accreditation expectancy effects (${\beta}=0.258$) and awareness of infection control (${\beta}=0.556$), and non-accredited dental hospitals were influenced by the number of employees (${\beta}=0.567$) and awareness of infection control (${\beta}=0.376$). Conclusions: It is necessary to develop efficient and systematic infection control programs to improve the awareness and practice of infection control in dental hygienists and patient's safety in the clinical field.

Microbial community and composition in stormwater runoff from mixed land use land cover (LULC) catchment with ongoing land development was diverse across the hydrological stage due different environmental parameters (hydrometeorological and physicochemical) and source of runoff. However, limited studies have been made for bacterial composition in this catchment. Therefore, this study aims to: (1) quantify the concentration of fecal indicator bacteria (FIB), stormwater quality and bacterial composition and structure according to hydrological stage; and (2) determine their correlation to environmental parameters. The 454 pyrosequencing was used to determine the bacterial community and composition; while Pearson's correlation was used to determine the correlation among parameters-FIB, stormwater quality, bacterial composition and structure-to environmental parameters. Results demonstrated that the initial and peak runoff has the highest concentration of FIB, stormwater quality and bacterial composition and structure. Proteobacteria, Bacteroidetes, Actinobacteria and Firmicutes were dominant bacteria identified in this catchment. Furthermore, the 20 most abundant genera were correlated with runoff duration, average rainfall intensity, runoff volume, runoff flow, temperature, pH, organic matter, nutrients, TSS and turbidity. An increase of FIB and stormwater quality concentration, diversity and richness of bacterial composition and structure in this study was possibly due to leakage from septic tanks, cesspools and latrines; feces of domestic and wild animals; and runoff from forest, destroyed septic system in land development site and urban LULC. Overall, this study will provide an evidence of hydrological stage impacts on the runoff microbiome environment and public health perspective.
