In the existing ship sales market, prices determined based on the prices of similar ship types that recently traded. ince the 2008 financial crisis, ship prices have fluctuated, and ship price criteria have become ever more necessary to the imminent value of the ship. Therefore, this research used the hedonic price model to estimate imminent values of ships. In this study, the influence on ship prices was analyzed by the value of each characteristic and an estimated functional formula was. Out of the four models suggested by the hedonic price model, an optimal model was selected with variance inflation factors and a stepwise selection. For this, the influence of determinants of ship prices was analyzed based on actually traded ships and characteristic data. The selected model s the Log-Line model; as a result of regression analysis, eight variables, including DWT, Age, Market Value, Short-Term Charter, Long-Term Charter, Enbloc, Special Survey Due and Builder were to affect the ship price model. This model is expected to be useful for objective and balanced ship price evaluation.

Evaluation items were deducted by based on literature materials to supplement the evaluation system of rock cut-slope in national road. Delphi survey of experts were conducted to review the final evaluation items. As a result of reviewing the significance through stepwise multiple linear regression, all of deducted items were statistically significant because these had lower P-value than 0.05. And It was confirmed that the items were selected appropriately as they had relatively similar levels of the weight. In consideration of CVR and reliability both suggested items and existing items, the exclusible items was selected and new items can complement existing evaluation system were added. Finally 18 rock cut-slope evaluation items was deducted.

This study investigated the effects of empathy, self-control, and smartphone dependency on the interpersonal relationships of nursing students. The survey participants were 157 students in A city. The data was collected through self-report questionnaires that were obtained from May 27 2019 to May 31 2019. The data was analyzed using descriptive statistics and Independent t-tests, One-way ANOVA, Pearson correlation coefficients, and Stepwise multiple regression analysis of the SPSS 14.0 program. As a result, self-control (F=5.319, p=.006) and smartphone dependency (F=4.854, p=.009) showed significant differences according to the school records. Smartphone dependency (t=-3.381, p<.001) showed significant differences according to smartphone use. Age was found to have a statistically positive correlation with self-control (r=.194, p=.015) and it had a negative correlation with smartphone dependency (r=-.223, p=.005). Self-control was found to have a statistically positive correlation with empathy (r=.244, p<.01), interpersonal relationship (r=.540, p<.001). and negative correlation with smartphone dependency (r=-.432, p<.001). Empathy was found to have a statistically positive correlation with interpersonal relationships (r=.476, p<.001). Stepwise multiple regression analysis revealed that the predictors of interpersonal relationships were self-control (β=.477, p<.001), empathy (β=.359, p<.001), and smartphone use (β=.208, p<.01) which accounted for 45.0% of all the variance (F=12.029 p<.01). An enhancement program of nursing students' interpersonal relationships is needed that considers their self-control, empathy, and smartphone use.

The purpose of this study was to investigate the effects of knowledge and risk perception of coronavirus disease-2019 on preventive health behavior among nursing students. The survey participants were 291 students in A city. Data were collected using self-report questionnaires between August 1 and 20, 2020. Data were analyzed using descriptive statistics, the independent t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression in SPSS ver. 18.0. Knowledge of COVID-19 was significantly dependent on age and school records. Risk perceptions were significantly dependent on educational grades. Age, health status, knowledge, and risk perception had significant effects on preventive health behavior, which was found to be positively correlated with knowledge and risk perception. Stepwise multiple regression analysis revealed that age significantly predicted preventive health behavior (β=.188, p<.01), health status (β=-.245, p<.001), knowledge (β=.254, p<.001), and risk perception (β=.191, p<.001) that it accounted for 18.9% (F=17.904, p<.001) of the variance. An educational program is required to enhance the preventive health behavior of nursing students in a background of COVID-2019 that considers student age, health level, knowledge, and perception of risk.

This study examined the factors affecting blood donation intention and behavior in college students based on the theory of planned behavior. The subjects were 258 students from one college in G city, and the data was collected by a survey using self-administered questionnaires structured from June 3 to June 14, 2013. The data was analyzed using the SPSS 19.0 program, the variables affecting the blood donation intention were analyzed by stepwise multiple regression, and the variables affecting the blood donation behavior were analyzed by Logistic regression. The factors affecting the blood donation intention were in order the perceived behavioral control, attitude toward the behavior and subjective norm, and the explanatory power was 65.6%. In addition, the factor affecting the blood donation behavior was only the blood donation intention (OR=1.129, p=.010) except for perceived behavioral control. Therefore, the perceived behavioral control, attitude and subjective norm should be considered when developing blood donation programs for college students.

The participants were 170 nurses working in integrated nursing care units of three general hospitals located in Seoul and Gyeonggi-do. Data were analyzed using independent t-test, ANOVA, Scheffé, Pearson's correlation and stepwise multiple regression analysis. Burnout was significantly different according to turnover intention, job satisfaction, health status. Burnout showed a positive correlation with compassion fatigue and a negative correlation with compassion satisfaction and relation oriented culture. Regression analysis revealed that compassion fatigue, compassion satisfaction, relation oriented culture and age were significant variables affecting the burnout, and the lower the age, the higher the burnout. Therefore, strategies to decrease compassion fatigue and to enhance compassion satisfaction and positive aspects of relation oriented culture for lower age nurses group are needed.
