This study investigated how the awareness about marriage, the value of children, and the motivation for childrearing influences childbirth will in nursing students. The data was collected from May 1 to May 30, 2019, and 248 data samples were finally used for analysis. The collected data was analyzed using the SPSS /WIN 22.0 program. Descriptive statistics, Pearson's correlation coefficients, t-tests, ANOVA, Scheffe's test and multiple regression analysis were all calculated. The average of awareness about marriage was 3.39±.38, the average of the value of children was 2.72±0.39, the average motivation of childrearing was 2.73±0.78 and the average of childbirth will was 3.12±0.48. The childbirth will according to the general characteristics, was significantly different according to age (F=6.002, p=.003). Among the awareness about marriage, conservative view on marriage(r=.207, p=.001), active view on marriage(r=.226, p<.001), instrumental view on marriage(r=.181, p=.004), and motivation of childrearing(r=.283, p<.001) showed positive correlation ed with childbirth will. Childbirth will was negatively correlated with passive view on marriage (r=-.292, p<.001), and the value of children (r=-.226, p<.001). The factors affecting childbirth will of the study subjects were age(β=.155, p=.007), passive view on marriage(β=-.383, p<.001), motivation of childrearing (β=.315, p<.001), and the explanatory power was 23.6%. According to this study, it is necessary to confirm the effects of developing an intervention program and applying this program to improve the decisions of nursing students concerning marriage and having children.

This study aims to identify the mediating effect of school satisfaction in the effect of self-esteem on resilience, and to examine the relationship between brain function quotient and resilience. In this descriptive study, questionnaires and brainwaves were collected from 145 female high school students in Seoul from November 22 to December 23, 2012. Data were analyzed by Pearson's correlation coefficient and three-step mediated regression analysis using SPSS 21.0. Among brain function quotients, stress resistance quotient were highly correlated with resilience, and both attention and brain quotient were significantly correlated with resilience. Moreover, school satisfaction showed the mediating effect in the effect of self-esteem on resilience. The findings suggest that brain function quotient, in specific, stress resistance quotient, should be considered in studies regarding resilience. Furthermore, predictor variables of resilience such as self-esteem and school satisfaction should be considered for preventive and therapeutic intervention to reduce various maladaptive problems in adolescents.

Echocardiographic measurements of cardiac output, including the modified Simpson's method, Automated Contour Tracking(ACT) method, and left ventricular outflow method are well described methods of evaluating cardiac function due to its reliability and the benefits of its non-invasive technique in human medicine. The purpose of this study was to evaluate the accuracy of an echocardiography estimate of cardiac output in isoflurane-anesthetized beagle dogs and was to compare the ACT method to the other methods used in measurement of cardiac output. In healthy beagle dogs, cardiac output results by echocardiography estimate methods showed an excellent correlations with those by the thermodilution method (The modified Simpson's method : r = 0.815, $r^2=0.665$, y = 0.434x + 0.311 ; ACT method : r = 0.86, $r^2=0.748$, y = 0.391x + 0.242 ; ventricular outflow method : r = 0.691, $r^2=0.478$, y = 0.593x + 0.242). Among the results obtained, the ACT method showed the highest correlation coefficient. In conclusion, our study demonstrated that echocardiography estimate methods did not prove to be suitable in accurately measuring absolute cardiac output values but showed an excellent correlation with thermodilution method. Therefore, by using the measurement of cardiac output as supplemental data, echocardiography estimate methods can be used for detection and correction of hemodynamic disturbances during emergency and anesthesia in veterinary practice.

This study was conducted to identify the correlation between the school-life stress, depression and college adjustment of dormitory residents, in order to provide the basic data needed to establish a strategy to improve the adjustment of college students. The subjects were 210 students in Korea. The data were collected using a self-report questionnaire from September 13 to 19, 2014, and analyzed by frequency, t-test, ANOVA and Pearson's correlation using the SPSS Win 21 program. The school-life stress, depression and college adjustment of the students residing in the dormitory on a 5-point scale were 2.43, 1.88 and 3.81, respectively. School-life stress had a significant positive correlation with depression (r=.639, p<.001) and significant negative correlation with college adjustment (r=-.709, p<.001). Depression had a significant negative correlation with college adjustment (r=-.788, p<.001). Those students with a higher school-life stress showed higher levels of depression and lower levels of college adjustment. Those students with a higher level of depression showed a lower level of college adjustment. Therefore, it is necessary to develop and test a suitable program in order to understand the differences between psychological adjustment based on gender, and to decrease school-life stress and depression and increase college adjustment.

In the recent years, the internet has become accessible without limitation of time and location to anyone with smartphones. It resulted in more convenient travel information access both on the pre-trip and en-route phase. The main objective of this study is to conduct a stationary test for traffic information web/mobile application access indexes from TCS (Toll Collection System); and analyzing the relationship between the web/mobile application access indexes and actual traffic volume on expressways, in order to analyze searching behavior of expressway related travel information. The key findings of this study are as follows: first, the results of ADF-test and PP-test confirm that the web/mobile application access indexes by time periods satisfy stationary conditions even without log or differential transformation. Second, the Pearson correlation test showed that there is a strong and positive correlation between the web/mobile application access indexes and expressway entry and exit traffic volume. In contrast, truck entry traffic volume from TCS has no significant correlation with the web/mobile application access indexes. Third, the time gap relationship between time-series variables (i.e., concurrent, leading and lagging) was analyzed by cross-correlation tests. The results indicated that the mobile application access leads web access, and the number of mobile application execution is concurrent with all web access indexes. Lastly, there was no web/mobile application access indexes leading expressway entry traffic volumes on expressways, and the highest correlation was observed between webpage view/visitor/new visitor/repeat visitor/application execution counts and expressway entry volume with a lag of one hour. It is expected that specific individual travel behavior can be predicted such as route conversion time and ratio if the data are subdivided by time periods and areas and utilizing traffic information users' location.

In modern society, the amount of information has been significantly increased according to the development of Internet and IT convergence technology and that leads to develop information obtaining and searching technologies from lots of data. Although the system integration for medicare has been largely established and that accumulates large amounts of information, there is a lack of providing and supporting information for nursing activities using such established database. In particular, the judgement for the intervention of pains depends on the experience of individual nurses and that leads to make subjective decisions in usual. In this paper, a pain nursing supporting method that uses the existing medical data and performs collaborative filtering is proposed. The proposed collaborative filtering is a method that extracts some items, which represent a high relativeness level, based on similar preferences. A preference estimation method using a user based collaborative filtering method calculates user similarities through Pearson correlation coefficients in which a neighbor selection method is used based on the user preference.
