Objectives: The purpose of the study is to examine the correlation and influencing factors among ethics position, self-esteem, and perception of patient medical information protection in the dental hygiene students. Methods: This is a cross sectional study using the structured questionnaire. A self-reported questionnaire was completed by 202 dental hygiene students using the stratified sampling method from September 1 to November 1, 2013. The questionnaire was modified and complemented from Ethics Position Questionnaire (EPQ). The questionnaire included EPQ, self-esteem, and perception of patient medical information protection. Data were analyzed by independent t-test, one way ANOVA, Duncan's multiple comparison analysis, Pearson's correlation analysis, and stepwise multiple regression analysis using IBM SPSS Statistics 21.0 program. Results: There was a positive correlation among all the variable including idealism position, self-esteem, and perception of patient medical information protection, The factors influencing on the perception of patient medical information protection were idealism position (${\beta}=0.271$, p<0.001) and self-esteem (${\beta}=0.248$, p<0.001). The corrected explanation power of the model was 15.1%. Conclusions: As the idealism position and self-esteem become higher, the perception of patient medical information protection gets higher. Therefore, this study suggests that it is needed to develop and vitalize implement the appropriate programs enhancing ethics consciousness, proper position, and self-esteem in the dental hygiene students receiving the education for their professionalism in the dental hygiene curricula.

Purpose: The purpose of this study was to explore self-directed learning ability and its affecting factors among undergraduate students. Methods: A descriptive cross-sectional study design was used. Using a convenience sampling method, data were collected from 196 undergraduate students enrolled in one national university. Negative psychological tendency (i.e. Type D personality), academic engagement, and self-directed learning ability were assessed using a structured questionnaire. Data were analyzed by descriptive statistics, t-test, and analysis of covariance, Pearson's correlation coefficients, and stepwise multiple linear regression, using SPSS/WIN 23.0 program. Results: The mean age of the students was $21.61{\pm}2.40years$ and 56.6% were male students. Approximately, one third (n=67, 34.2%) of the students had Type D personality. The average scores of academic engagement and self-directed learning ability were $3.01{\pm}1.14$ and $3.46{\pm}0.50$, respectively. After controlling for sociodemographic variables, the Type D personality and academic engagement were significant predictors of self-directed learning ability (${\beta}=.64$, p<.001; ${\beta}=-.13$, p=.021, respectively). This model explained 53.6% of the variance in self-directed learning ability. Conclusion: The study identified that Type D personality and academic engagement affect self-directed learning ability of undergraduate students, one in a negative way, the other in a positive way. Educators and educational policy makers need to make efforts to include interventions and strategies that increase academic engagement and change negative psychological dispositions such as D-type personality in the undergraduate education curriculum.

This study used data from the 3rd and 11th year of the Korean Welfare Panel to evaluate the effects of the Long-Term Care Insurance(LTCI) system on the consumption and expenditure of LTCI users' households. The study consisted of program group using LTCI and control group not using. Chi-square and t-test were used for the characteristic differences among the groups, and the difference of consumption expenditure was identified by multiple regression analysis. As a result, LTCI had a statistically significant effect on the health care costs of LTCI users' households, resulting in an increase in health care costs(${\beta}=3.06$). However, there was no statistically significant effect on the total cost of living, basic cost, education cost, and recreation/entertainment cost. Therefore, in order to show the effect of LTC system, we should try to reduce of self-pay and improve the contents and quality of the service of the LTC system.

Purpose: The purpose of this study was to investigate bone mineral density(BMD) and fear of falling and falls efficacy in the middle and old aged women over 50 years. Methods: The subjects consisted of 409 women. One-way ANOVA, Pearson's correlations and multiple regression were used to test the BMD, fear of falling and falls efficacy scale by using SPSSWIN 12.0. The BMD of the calcaneus were measured with peripheral dual energy x-ray absorptiometry(DEXA). Results: The average age was 63 years old and the average T-score was -3.21 in patient with osteoporosis, -1.72 with osteopenia, and .13 with normal. There were significant differences in the status of the BMD according to age(p=.000), height(p=.000), weight(p=.000), married status(p=.000), age of menarche(p=.002), and menopause(p=.002). The fear of falling was related with falls efficacy(r=-.247, p=.01), BMD(r=-.337, p=.01). Falls efficacy($\beta$=-.21, p=.000)and BMD($\beta$=-.26, p=.000) were predicting variables of fear of falling. The model explained 13% of the variance in fear of falling(F=27.38, p=.000). Conclusion: Fear of falling and falls efficacy were related with the bone mineral density. Falls efficacy and BMD may be useful for the predicting fear of falling for women in middle and old age. Further studies with assessment of fall-related risk-factors and a longitudinal study are necessary to assess with falls efficacy, and BMD with age.

Objectives: Residents of a single room occupancy (Jjok-bang) in Seoul are at high risk of having mental health issues. The majority of residents live in single households with past traumatic experiences including self-deprivation and social exclusion. This study was to investigate the association between mental health and socio-ecological factors at the intrapersonal and community levels. Methods: We conducted face-to-face surveys in Dongja-dong Jjok-bang area in June, 2014. Of 78 participants, 76% were male and the mean age was 60 years (SD=11.53). A multiple regression was used to analyze the association among depression, a sense of well-being, socio-ecological factors, and perceived empowerment and community solidarity. Results: Perceived empowerment (${\beta}=0.83$; 95% CI=0.40, 1.26) and community solidarity (${\beta}=0.52$; 95% CI=0.04, 1.01) were positively associated with a sense of well-being. Participants with empowerment (${\beta}=-2.55$; 95% CI=-4.86, -0.23) and those with community solidarity (${\beta}=-2.36$; 95% CI=-4.94, 0.21) were negatively associated with being depressed. Conclusion: Mental health of the residents in Jjok-bang was more influenced by empowerment and community solidarity than socio-demographic factors. It is necessary to improve public health infrastructures that can enable the residents to enhance empowerment and community solidarity utilizing socio-ecological perspectives.

Rheological properties such as yield stress and viscosity is the main parameters to determine the fluidity of the debris flow. In this study, several series of rheometer tests were performed to investigate rheological properties of fine-grained soil samples with various sand contents and various liquidity indices. Test results indicated that the general shape of the flow curves for fine-grained soils had characteristics of a shear thinning fluid, with a decrease in viscosity as shear rate increases. The yield stress and viscosity of fine-grained soil samples with same sand content gradually decreased as the liquidity index increased. At the same liquidity index, yield stress and viscosity of fine-grained soil increased with an increase in sand content. The yield stress and viscosity of fine-grained soil greatly decreased with a slight increase in water content. Also, the yield stress and viscosity tend to increase with increasing concentration by volume($C_v$) of the fluid matrix. The values of the four coefficients ${\alpha}_1$, ${\alpha}_2$, ${\beta}_1$, and ${\beta}_2$ were obtained by regression analysis for each fine-grained soil.

The purpose of this study was to investigate the effects of emotional regulation between clinical practice stress and nursing professionalism in nursing students. Participants were 192 nursing students and data were collected from September to November, 2015. This study has shown that nursing professionalism is negatively associated with clinical practice stress (r=-.40, p<.001) and positively associated with emotional regulation (r=.55, p<.001). In addition, a negative correlation has been found significant between emotional regulation and clinical practice stress (r=-.20, p<.001). In a final model of hierarchial multiple regression, professor support (${\beta}=.19$, p<.01), satisfaction with nursing as a major (${\beta}=.14$, p<.05), clinical practice stress (${\beta}=-.19$, p<.01) and emotional regulation (${\beta}=.32$, p <.001) were associated with nursing professionalism. In this study, we also have shown that emotional regulation does not play a moderating role on the relationship between clinical practice stress and nursing professionalism. The results of this study suggests that, in order to improve nursing professionalism, it is important to promote support system, develop clinical-practice-stress-relief programs, and enhance emotional regulation training for nursing students.

Aims and Background: The purpose of the research was to study the prognostic value of tumor 18F-FDG PET-based parameters in neoadjuvant chemoradiation for patients with squamous esophageal carcinoma. Methods: Sixty patients received chemoradiation therapy followed by esophagectomy and two 18FDG-PET examinations at pre- and post-radiation therapy. PET-based metabolic-response parameters were calculated based on histopathologic response. Linear regression correlation and Cox proportional hazards models were used to determine prognostic value of all PET-based parameters with reference to overall survival. Results: Sensitivity (88.2%) and specificity (86.5%) of a percentage decrease of SUVmax were better than other PET-based parameters for prediction of histopathologic response. Only percentage decrease of SUVmax and tumor length correlated with overall survival time (linear regression coefficient ${\beta}$: 0.704 and 0.684, P<0.05). The Cox proportional hazards model indicated higher hazard ratio (HR=0.897, P=0.002) with decrease of SUVmax compared with decrease of tumor size (HR=0.813, P=0.009). Conclusion: Decrease of SUVmax and tumor size are significant prognostic factors in chemoradiation of esophageal carcinoma.

Purpose: The purpose of this study was to explore the intentions and influencing factors of intentions to care for New Influenza A ($H_1N_1$) patient Methods: This study involved a descriptive design using self-administered questionnaire. Intentions to care for H1N1 patient was evaluated by prediction tool, based on the Theory of Planned Behavior (TPB). The data were analyzed by SPSS 17.0 using descriptive statistics, t-test, ANOVA with a Scheffe test, Pearson's correlation and multiple regression analysis. Results: The level of intention was high, attitude was negative, subjective norm was high, and perceived behavioral control was moderate. The general regression model with intention as a dependent variable was statistically significant (F=39.31, p<.001). 28.1% of variance in intention was explained by subjective norm (t=8.75, p<.001), and perceived behavioral control (t=4.28, p<.001). Among the predictors, subjective norm had the greatest effect on intention (${\beta}=.44$). The nurse with the higher subjective norm and more positive perceived behavioral control reported the higher intention. Conclusion: The findings of this study suggested that the various aspects of nurse's characteristics should be considered when establishing strategies to improve the nurse's intention for care of infectious disease.
