The purpose of this study is to examine the effect of female adolescents' rejection sensitivity, impulsivity and guilt on their binge eating behavior. Questionnaires on rejection sensitivity, impulsivity, guilt and binge eating behavior were administered to 607 female adolescents in Changwon and Ulsan. Of 572 collected copies, 402 were deemed valid and statistically analyzed through frequency analysis, mean and standard deviation, t-test, Pearson's correlation analysis, multiple regression analysis and stepwise multiple regression analysis using SPSS Win 12.0. The results of the study were as follows: 1) School type was found to make a significant difference in rejection sensitivity, overall impulsivity, guilt and binge eating behavior; however, its influence was not significant on the sub-factors of impulsivity: motor impulsivity, unplanned impulsivity and cognitive impulsivity. 2) For female middle school students, rejection anger sensitivity, rejection depression sensitivity and motor impulsivity were found to have a significant influence on binge eating behavior for both middle school and high school girls. Guilt, however, was found to be influential for female high school students only. 3) Impulsivity was found to have a partial mediating effect on the relationship between female adolescents' rejection sensitivity and binge eating behavior.

This study evaluated the moral sensitivity, self-assertiveness, ethical decision-making confidence and their correlations, and the factors that influence ethical decision-making confidence among nurses working in a long-term care hospital. Overall, 149 nurses working in a long-term care hospital in G Province were evaluated. The date was collected from November 30 2019 to December 18, 2019 and analyzed using SPSS/WIN 21.0 program. The mean of moral sensitivity among nurses was 4.94, the mean of self-assertiveness was 3.17 and the mean of ethical decision-making confidence was 3.49. The self-assertiveness will, according to the general characteristics, was significantly different according to experienced moral distress, and there was a significant difference in the degree of ethical decision-making confidence according to social positions and experience of ethical education. There were positive correlations between the ethical decision-making confidence and moral sensitivity (r=.382, p<.001) and self-assertiveness (r=.224, p<.01). Regression analysis revealed that the factors that significantly influenced ethical decision-making confidence were moral sensitivity, self-assertiveness and ethical education during nursing practice, which explained 25.0% of variance in ethical decision-making confidence. Therefore, to improve ethical decision-making confidence of nurses, programs should be developed that improve moral sensitivity and self-assertiveness by promoting ethical education.

Clean development mechanism (CDM) validity study was conducted to suggest better and more adaptable CDM scenario on water treatment plant (WTP). Potential four scenarios for CDM project; improvement of intake pumping efficiency, hydro power plant construction, solar panel construction and system optimization of mechanical mixing process were evaluated on S-WTP in Korea. Net present value (NPV) of each scenario was estimated based on sensitivity analysis with the variable factors to investigate the CDM validity percentile. Hydro power plant construction was the best option for CDM business with 97.76% validity and $1,127,069 mean profit by 9,813 $tonsCO_2e$/yr reduction. CDM validity on improvement of intake pumping efficiency was 90.2% with $124,305 mean profit by huge amount of $CO_2$ mitigation (10,347 $tonsCO_2e$/yr). System optimization of mechanical mixing process reduced 15% of energy consumption (3,184 $tonsCO_2e$/yr) and its CDM validity and mean profit was 77.25% and $23,942, respectively. Solar panel construction could make the effect of 14,094 $tonsCO_2$ mitigation annually and its CDM validity and mean profit was 64.68% and $228,487, respectively.

1. Objectives The purpose of this study was to investigate the high-sensitivity C-reactive protein (hsCRP) related characteristics found in each Sasang Constitutional type. 2. Methods This cross-sectional epidemiological study was conducted using data from 2,842 men and women. After typing each participant into one of the four Sasang constitutional types, they were analyzed on various cardiovascular disease-related variables. 3. Results 1) The predictors of cardiovascular disease (metabolic syndrome, high risk FRS group, high risk hsCRP group) was found to show the highest prevalence in the Taeeum type. 2) In the group with metabolic syndrome, the mean hsCRP concentration in the Taeeum and Soyang types were higher than in the Soeum type. In the group without metabolic syndrome, the mean hsCRP concentration in the Taeeum type were higher than in the Soyang and Soeum types. 3) In the FRS low risk group, the mean hsCRP concentration were higher in order of Taeeum type > Soyang type > Soeum type. In the FRS high risk group, the mean hsCRP concentrations were not significantly different among the Sasang constitutional types. 4. Conclusions The results of this study suggest that the Taeeum constitutional type is a risk factor for high hsCRP and cardiovascular disease. These findings suggest that the prevention of cardiovascular disease is more important in the Taeeum type compared to other constitutional types. Moreover, preventive measures are warranted even in the Taeeum-type persons with low clinical cardiovascular risk.

The purposes of this study were : 1) to evaluate validity of a pain rating scale using the level of correlation between the Korean Pain Rating Scale(KPRS), Short -Form KPRS(SKPRS) and the Graphic Rating Scale(GRS). 2) to identify sensitivity of the scale using pain behavior of patients with chronic pain. Of the 2025 patients with chronic pain who visited the orthopedic and neurosurgical out - patients departments of 11 university hospitals in various districts of Korea, 520 subjects were selected through convenient sampling and responded to the questionnaires by mail. The results of the study can be summarized as follows : 1. The mean pain score measured by the KPRS was 444,85 : the mean sensory score was 209.47, the mean affective score, 147.63 and the mean miscellaneus score. 87.75. The mean pain score measured by the GRS was 20.11 : the mean sensory intensity score, 10.54. and the mean distress score, 9.57. 2. The average number of hours of rest during the day was 3.3, the average score of discomfort in carrying out ADL was 99, the average frequency of pain relieving practices was 3.0, the average number of pain sites was 3.6. 3. The most sensitive scale to differentiate each group was the GRS, the KPRS and SKPRS were less sensitive than the GRS. 4. The intercorrelation between the KPRS total score and the GRS score(.500) as well as that of the SKPRS score were highly correlated(.652), but intercorrelation between the SKPRS score and the GRS score(.172) was not high. Based on the above results, it was found that the SKPRS must be studied further to obtain validity.

The accuracy of ozone sensitivity coefficients estimated with HDDM (High-order Decoupled Direct Method) can vary depending on the $NO_x$ (Nitrogen Oxides) and VOC (Volatile Organic Compound) conditions. In order to evaluate the applicability of HDDM over the Seoul Metropolitan Area (SMA) during a high ozone episode in 2007 June, we compare BFM (Brute Force Method) and HDDM in terms of the $1^{st}$-order ozone sensitivity coefficient to explain ozone change in response to changes in NOx and VOC emissions, and the $2^{nd}$-order ozone sensitivity coefficient to represent nonlinear response of ozone to the emission changes. BFM and HDDM estimate comparable ozone sensitivity coefficients, exhibiting similar spatial and temporal variations over the SMAduring the episode. NME (Normalized Mean Error) between BFM and HDDM for the episode average $1^{st}$- and $2^{nd}$-order ozone sensitivity coefficients to NOx and VOC emissions are less than 3% and 9%, respectively. For the daily comparison, NME for the $1^{st}$- and $2^{nd}$-order ozone sensitivity coefficients are less than 4% ($R^2$ > 0.96) and 15% ($R^2$ > 0.90), respectively. Under the emission conditions used in this study, two methods show negative episode average $1^{st}$-order ozone sensitivity coefficient to $NO_x$ emissions over the core SMA. The $2^{nd}$-order ozone sensitivity coefficient to $NO_x$ emissions leads ozone to respond muchnonlinear to the reduction in $NO_x$ emissions over Seoul. Nonlinear ozone response to reduction in VOC emissions is mitigated due to the $2^{nd}$-order ozone sensitivity coefficient which is much smaller than the $1^{st}$-order ozone sensitivity coefficient to the emissions in the magnitude.

Purpose: To determine the diagnostic value of eosinopenia and the neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of early onset neonatal sepsis (EONS). Methods: This cross-sectional study was conducted in the Neonatology Ward of R.D. Kandou General Hospital Manado between July and October 2017. Samples were obtained from all neonates meeting the inclusion criteria for EONS. Data were encoded using logistic regression analysis, the point-biserial correlation coefficient, chi-square test, and receiver operating characteristic curve analysis, with a P value <0.05 considered significant. Results: Of 120 neonates who met the inclusion criteria, 73 (60.8%) were males and 47 (39.2%) were females. Ninety (75%) were included in the sepsis group and 30 (25%) in the nonsepsis group. The mean eosinophil count in EONS and non-EONS groups was $169.8{\pm}197.1cells/mm^3$ and $405.7{\pm}288.9cells/mm^3$, respectively, with statistically significant difference (P<0.001). The diagnostic value of eosinopenia in the EONS group (cutoff point: $140cells/mm^3$) showed 60.0% sensitivity and 90.0% specificity. The mean NLR in EONS and non-EONS groups was $2.82{\pm}2.29$ and $0.82{\pm}0.32$, respectively, with statistically significant difference (P<0.001). The diagnostic value of NLR in the EONS group (cutoff point, 1.24) showed 83.3% sensitivity and 93.3% specificity. Conclusion: Eosinopenia has high specificity as a diagnostic marker for EONS and an increased NLR has high sensitivity and specificity as a diagnostic marker for EONS.
