Purpose: The purpose of this study is to examine the factors influencing the barriers faced by Korean nurses in addressing the patients' sexual health. Methods: The subjects in this study were nurses working at hospitals in Seoul and Jeonju. The data for this study were collected between November 2008 and December 2008. The subjects were assured of anonymity and confidentiality. Results: The barriers to addressing the patients' sexual health were moderate in the subjects. The nurses had moderate sexual knowledge and communication skills. In a stepwise regression analysis, the areas of work, communication skills, participation in sexual health training, and experience in Obstetrics and Gynecology accounted for 18.3% of the variance of the barrier for addressing the patients' sexual health. Conclusion: These findings emphasize the need for the development of a patient-centered sexual health-related curriculum for nurses, which has been briefly discussed in Korea. An educational program that improves the nurses' communication skills will be effective in reducing the barriers to addressing the patients' sexual health and will help the nurses become sexual health specialists.

Purpose: This study was done to identify the relationship between social support and morale in the elderly. Method: A structured questionnaire was carried out from April, 2003 to June, 2003 on 203 elderly. The data was analyzed with a SPSS program for descriptive statistics, Pearson's correlation coefficients, t-test, ANOVA, and stepwise multiple regression was done Result: The level of social support was moderate, and family support was the highest score. In types of support, appraisal support was the highest score. The level of morale was slightly lower than moderate, and the score of social support showed significantly positive correlation with morale. In general characteristics, several variables were significantly related to social support and morale. The most powerful predictor of morale was material support by family and the variance was 19.6%. A combination of material support by family, emotional support by relatives, level of satisfaction with pocket money, perceived health, level of intimacy with one's children, and material support by friends account for 43.3% of the variance in morale of the elderly. Conclusion: To increase the morale of the elderly, it is necessary to consolidate material support by family and relatives.

This study examined the effect of waiting in a service queue on the evaluation of service quality focused on its overall process, mediators and moderators The conceptual model of this paper integrates key variables derived from previous studies of consumer waiting behavior. Data obtained from actual customers in service queue at a hospital was used to test the theoretical framework. First, results from the path analysis confirm that negative affect and acceptability of the wait function as mediators in the process that the perceived duration of the wait affects customer's evaluation of overall service quality. Second, the analysis of the data, with the use of moderate regression shows that disconfirmation of wait time expectations, transaction importance, stability of wait time and wait environment work as moderate variables for the relationship between perceived duration of wait and negative affect. For the relationship between perceived wait time and acceptability of the wait, on the other hand, only transaction import ante shows a significant effect as a moderator.

Background: The purpose of this study is to investigate the factors affecting the healthy living practice rate such as non-smoking, moderate drinking, walking, and low-salt diet by elementary municipality (so called, 'si-gun-hu'). Methods: The 2016 Korean Community Health Survey was used for the analysis. The theoretical model is founded upon the Anderson model, and both the multiple linear regression analysis and the beta regression analysis was performed for estimation. Results: As a result of the beta regression analysis, healthy living practice rate was found to be significantly higher in the areas with a less number of cigarette retailers, participating in healthy city projects, a low proportion of people who perceive their body type as obesity, a higher proportion of women, and a lower proportion of spouses. Conclusion: In order to improve healthy living practices, the regulations on health risk businesses, the spread of Healthy City project, and policy efforts awaring obesity are recommended.

In this study three log-transformed linear regression models are compared with the focus of bias correction problem. The models are the traditional simple linear regression estimator (SL), the quasi maximum likelihood estimator (QMLE) and the minimum variance unbiased estimator (MVUE). Using such models, suspended solid loads can be estimated using the discharge - suspended solid data set that has been measured by NIER Nakdong River Water Environment Laboratory. As a result, SL shows negative bias for most values of the measured discharge range. QMLE is nearly unbiased for moderate values of the measured discharge range, but shows increasingly positive bias for either large or small value of the measured discharge range. MVUE is unbiased. It is also analyzed how the estimated regression coefficient and exponent are distributed along Nakdong river main stream.

Lymphangiomas are congenital malformations of the lymphatic system. Cervicofacial lymphangioma represents 75% of all lymphangiomas. Surgical excision has been the treatment of choice, however the reported results have been unsatisfactory. Various sclerosants have been tried to treat lymphangiomas, with variable results and considerable side effects. Herein we report the results of treatment using intralesional picibanil for lymphangioma. Between January 1996 and January 1998, 16 patients with lymphangiomas, 10 boys and 6 girls, were treated with intralesional picibanil injections. All cases were treated as a primary therapy. Eight lymphagiomas were located in the neck, and 2 in the cheek, 2 in the parotid, 2 in the trunk, 1 in the oropharynx, 1 in the thigh. Dose and method of intralesional injection was similar to that reported by Ogita in 1987. Complete regression was observed in 10 cases and marked regression(> 75% size decrease) in 2 cases and moderate regression(75%-25% size decrease) in 2 cases and poor regression(< 25% size decrease) in 2 cases. No serious side effect was observed except fever lasting for 2-3 days. Intralesional injection of picibanil for lymphangiomas represents a safe, easy and effective way of treatment with high success rate. Picibanil injection can be used as a primary therapy for lymphangiomas.

We have estimated the vertical column density (VCD) of formaldehyde (HCHO) on a global scale using a multiple linear regression method (MRM) with Ozone Monitoring Instrument (OMI) and Moderate-Resolution Imaging Spectroradiometer (MODIS) data. HCHO VCDs were estimated in regions of biogenic, pyrogenic, and anthropogenic emissions using independent variables, including $NO_2$ VCD, land surface temperature (LST), an enhanced vegetation index (EVI), and the mean fire radiative power (MFRP), which are strongly correlated with HCHO. To evaluate the HCHO estimates obtained using the MRM, we compared estimates of HCHO VCD data measured by OMI ($HCHO_{OMI}$) with those estimated by multiple linear regression equations (MRE) ($HCHO_{MRE}$). Good MRM performances were found, having the average statistical values (R = 0.91, slope = 1.03, mean bias = $-0.12{\times}10^{15}molecules\;cm^{-2}$, percent difference = 11.27%) between $HCHO_{MRE}$ and $HCHO_{OMI}$ in our study regions where high HCHO levels are present. Our results demonstrate that the MRM can be a useful tool for estimating atmospheric HCHO levels.

The purpose of this research is to find the factors affecting the academic education satisfaction of social entrepreneurs, and to analyse the moderate variable such as the study motivation among the factors. These factors includes the curriculum, the education management, the education facilities, the characteristics of instructors and the study motivation. To do this end, this study set up the research questionnaire from the study of Houle (1961) and Hyun and Kim (2010), and did the moderate regression analysis to test the hypothesis that the academic motivation can do as the moderate variable while affecting the education satisfaction. The study finds that the factors such as the curriculum, the education management, the education facilities and the characteristics of instructors show the statistically significant test results. Also the study motivation as a moderate variable shows significant result. Thus for educating the social entrepreneurs, the study motivation of them should be deeply considered.

Background: Pulsatility of cerebral arteries and aortic stiffness have been associated with white matter hyperintensities (WMH). We explored which is better correlated with the severity of WMH in a population with acute lacunar infarct. Methods: We included patients with acute small subcortical infarcts who underwent transcranial Doppler (TCD) and brachial ankle pulse wave velocity (baPWV). Exclusion criteria were any stenosis or occlusion on major cerebral arteries on magnetic resonance angiography; poor temporal insonation windows; ankle brachial index < 0.9; and atrial fibrillation. We assessed the performance of the pulsatility index of bilateral middle cerebral arteries (PI-MCA) and baPWV for predicting moderate-to-severe WMH, defined as an Age Related White Matter Changes score > 5, and then sought to find independent predictors using binary logistic regression analysis. Results: Eighty-three patients (56 males, mean age $61.5{\pm}11.4$) participated in the study. Uni-variate analysis showed old age and high PI-MCA were significantly correlated with moderate-to-severe WMH. However, baPWV was not associated with the severity of WMH. Multivariate analysis revealed old age (odds ratio per 1-year increase, 1.068; p = 0.044) and upper tertile of PI-MCA (odds ratio, 5.138; p = 0.049) were independently associated with moderate-to-severe WMH. Receiver-operating characteristics showed PI-MCA differentiated those with and without moderate-to-severe WMH with an area under the curve of 0.719. Conclusions: PI-MCA derived from TCD was better correlated with the severity of WMH than baPWV in a population with lacunar infarction. Pulsatility of cerebral arteries may better predict cerebral small vessel disease than the aortic stiffness index.

The first goal of this study is to confirm validity and reliability of service innovation and performance concepts in Chinese service industry and to verify positive relationship between the two concepts empirically. Furthermore, as the second goal of this study, we tried to check if Time Based Strategies and dFlexibility Based Strategies have positive moderate effect on the relationship. Based on the results of survey on 181 Chinese service companies, we verified that service innovation and performance are valid concepts and that the former has positive effect on the latter and, additionally, differentiation strategy, not cost leadership, showed positive moderate effect on that relationship.
