  • Korean youth spend tremendous time in school for preparing for college admissions. Their academic achievement and overall satisfaction with their lives are affected by how well they adapt to life in school. Successful adaptation to school is important enough to affect a student's future social life. One of the factors that affect adaptation to school is the psychological condition of adolescent anxiety. Anxiety is one of the common mental disorders that appear in people who are not familiar with new environments. Anxiety is known to be related to behavioral problems, and problems with psychological and emotional adaptation. This condition is dramatically increased in adolescents.Parental conflict in particular is known to be a major factor in affecting youth anxiety. As parental conflict became more severe, children felt more negative emotions such as anger, sadness and worry. Moreover, when a child's issue caused the parental conflict, there were more side effects in the emotional condition of the child. This study shows how parental conflict affects a child's anxiety and a child's school life.This problem is analyzed through structural equation modeling.

  • This study examined the relationship between professional self-concept, interpersonal relationship, coping, and clinical practice satisfaction of nursing college students. This was a descriptive study. The survey participants were 355 students in M city and I city. The data were collected from May 29 to June 16, 2017 and self-report questionnaires, including the Professional Self-concept Scale, Interpersonal Relationship Scale, Coping Scale, and Clinical Practice Satisfaction Scale. The data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression. Professional self-concept showed significant differences according to religion, income, and school records. Interpersonal relationships showed significant differences according to gender, income, and school records. Coping showed significant differences according to the school records. Professional self-concept had a statistically positive correlation with interpersonal relationship, clinical practice satisfaction, and approach coping. Stepwise multiple regression analysis showed that the predictor of professional self-concept was interpersonal relationships, approach coping, religion, school records, and avoidant coping, which accounted for 45.2% of the variance. These results highlight the need for enhancement programs of nursing college students' professional self-concept that consider their interpersonal relationships, coping, religion, and school records.

  • Two monitoring buoys equipped with ADCP were deployed at the deepest positions along the trough of the central Gwangyang Bay in spring 2006 in order to study the circulation in the bay. Northward velocity is commonly dominant at both stations located in the eastern part of the channel, which supports the cyclonic circulation accompanied by the southward flow in the western part. The southern station has a distinct two-layer structure with current reversal at 14 m depth and increasing northward velocity in the lower layer to 36 m depth close to the bottom. At the northern station the northward flow becomes accelerated due to the decrease in the cross-sectional area and this northward current is dominant even in the upper layer. In the modal structure from the EOF analysis, the first mode has 74% of total variance at the northern station whereas it is 67% but the baroclinic portion increases at the southern station. The typical northward velocity is about 10 cm/s which is associated with the cyclonic circulation. Subtidal variability due to the local wind effect is negligible, but the nonlocal response associated with offshore Ekman flux by the zonal wind is found during strong wind events.

  • Many trials to set up the correlation between the rock mass classification and the earth resistivity have been carried out to design tunnel support type based on the interpreted electrical resistivity acquired by surface electrical survey. But it is hard to find reports on the comparison of the real rock support type determined during the excavation with the electrical resistivity by the inversion of the survey data acquired before the tunneling. In this study, the rock mass classification based on the face mapping data and the resistivity inversion data are investigated to see if it is possible to design reliably the rock support type based on the surface electrical survey. To get the quantitative correlation, rock engineering indices such as RCR(rock condition rating), N(Rock mass number), Q-system and RMR(rock mass rating) are calculated. Since resistivity data has low resolution, Kriging method as a post processing technique which minimizes the estimated variance is used to improve resolution. The result of correlation analysis shows that the 2D electrical resistivity survey is appropriate to see the general trend of the geology in the sense of rock type, though there might be some local area where these two factors do not coincide. But the correlation between the result of 3D survey and the rock mass classification turns out to be very high, and then 3D electrical resistivity survey can make it possible to set up more reliable rock support type.

  • The purpose of this study was to investigate the influence of SNS addiction tendency, pathological narcissism, social support, and stress among university students. Data were collected via questionnaires from 385 students and were analyzed by descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients, and Stepwise multiple regression analysis using SPSS/WIN 19.0 program. The levels of SNS addiction tendency depended on gender, SNS usage time, SNS over-usage, health problem, and household economic status. SNS addiction tendency was significantly correlated with pathological narcissism, social support, and stress. Influential factors that affect SNS addiction tendency were pathological narcissism, SNS usage time, SNS over-usage, gender, social support, and academic performance, which explained about 39.4% of the variance. The results of this study indicate that nursing interventions are necessary to improve SNS addiction tendency, and also suggesting that such variables should be carefully considered in intervention programs for university students.

  • This study examined the factors influencingthe adaptation to university life of nursing students. Data were collected from 235 nursing students in three nursing schools in B and C city from November 15 to December 10, 2016, and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Correlations were found between adaptation to university life and life stress (r=-0.657, p<0.001) and between ego-resilience (r=0.455, p<0.001) and spiritual well-being (${\beta}=0.210$, p=0.025)(r=0.494, p<0.001). The adaptation to university life in participants showed a significant correlation between life stress (r=-0.657, p<0.001), ego-resilience (r=0.455, p<0.001), and spiritual well-being (r=0.494, p<0.001). The significant factors influencing the adaptation to university life were life stress (${\beta}=-0.418$, p<0.001), health status(${\beta}=0.213$ p<0.001), spiritual well-being (${\beta}=0.210$, p=0.025), satisfaction with major (${\beta}=0.146$, p=0.003), and ego-resilience (${\beta}=0.109$, p<0.001); these factors explained 56.5% of the variance. The findings suggest that adequate educational strategies are needed to reduce the life stress and increase health status, spiritual well-being, satisfaction on major, and ego-resilience in nursing students to promote their adaptation to university life.

  • This paper aims to examine systematically how audiences' exposure to crime news influences their multicultural acceptability. In particular, the analysis has focused on how the variance in the effects of contacts with crime news on foreigners takes place, according to the types of media and communication favored among the audiences. Also, with perceived risk toward crime as a mediating variable, this research scrutinizes the way crime news on foreigners comes to influence multicultural acceptability among the audiences. While various news sources and communication channels are influential in strengthening the perceived possibility of crime on the individual level, the results show, television seems to be particularly more effective with regards to the perceived prevalence of crime on the social level (RQ 1). Also, while contacts with crime news through 'dialogic' media rarely influence multicultural acceptability significantly, 'discursive' media and face-to-face contacts have negative impacts on the multicultural acceptability (RQ 2). Consequently, perceived risk on the social level seems to play the role of full mediation in the process where audiences' contact with crime news through discursive media influences their multicultural acceptability (RQ 3). Based on these findings, both theoretical and practical implications were discussed.

  • A fault is a geological structure that can be a migration path or a cap rock of hydrocarbon such as oil and gas, formed from source rock. The fault is one of the main targets of seismic exploration to find reservoirs in which hydrocarbon have accumulated. However, conventional fault detection methods using lateral discontinuity in seismic data such as semblance, coherence, variance, gradient magnitude and fault likelihood, have problem that professional interpreters have to invest lots of time and computational costs. Therefore, many researchers are conducting various studies to save computational costs and time for fault interpretation, and machine learning technologies attracted attention recently. Among various machine learning technologies, many researchers are conducting fault interpretation studies using the support vector machine, multi-layer perceptron, deep neural networks and convolutional neural networks algorithms. Especially, researchers use not only their own convolution networks but also proven networks in image processing to predict fault locations and fault information such as strike and dip. In this paper, by investigating and analyzing these studies, we found that the convolutional neural networks based on the U-Net from image processing is the most effective one for fault detection and interpretation. Further studies can expect better results from fault detection and interpretation using the convolutional neural networks along with transfer learning and data augmentation.

  • This research analyzed and compared the public library satisfaction level between South Korea and USA public library user. This research looked at the public library user's nominal complains to the library from various countries and analyzed the impact variance of customer satisfaction level by using four key factors(faculty, facility, online service, books). The results were, first, overall customer satisfaction level of USA average(m=3.91) was higher then South Korea average(m=3.08) with a difference of m=0.83. Second, in the outcome of the survey conducted in South Korea, all four key factors were strongly related to customer satisfaction level, whereas the survey conducted in the USA, only two key factors showed relation to the customer satisfaction level which were facility and online service. Lastly, In the survey conducted in South Korea, out of the four key factors, Faculty(${\beta}$=.838) and online service(${\beta}$=.496) were the only two key factors that influenced the customer satisfaction level. In the survey conducted in the USA, Facility(${\beta}$=.441) and online service(${\beta}$=.471) were the two key factors that influenced customer satisfaction level. Therefore, South Korea should invest in increasing online service and educating faculty service as well as managing more intensively in software type field policies.

  • The relationship between EI Nino-Southern Oscillation(ENSO) and drought in Korea is investigated using the cross correlation analysis. In this paper, Palmer Drought Severity Index(PDSI) is used as an index of drought and nine ENSO indicators are used. To obtain PDSI for Korea, the PDSI equation is derived using monthly precipitation and temperature in Korea. In addition, ENSO composite percentile analyses for PDSI, precipitation and streamflow in Korea are performed to verify the results of the cross correlation. Results of the cross correlation show that the link between drought in Korea and ENSO is statistically significant with 6% of the variance in PDSI for Korea explained by ENSO. The PDSI is negatively correlated with the equatorial Pacific Sea Surface Temperature and the Sea Level Pressure(SLP) at Darwin leading by about 16 months. However, the relationship of the PDSI with the Southern Oscillation Index and the SLP at Tahiti is positive correlation. The ENSO composite percentile analyses show that drought, precipitation and streamflow in Korea are associated with ENSO during 6 months from December of the ENSO ending year
