This study is a descriptive exploratory research aimed at identifying factors influencing the health-related quality of life(HRQOL) in middle-aged and senior-aged patients with complex chronic diseases. The study participants were extracted from the Korean Medical Panel annual data. A total of 2,408 patients, with two or more chronic diseases were included. The data were analyzed using STATA 15.0 software through descriptive statistics, t-tests, ANOVA, and multiple linear regression analysis. The research findings indicate that in middle-aged patients, educational level, household income, economic activity, stress, experience of despair, and basic needs satisfaction positively influence health-related quality of life. On the other hand, types of medical insurance, depressive feelings, and suicidal ideation exert a negative impact. In the case of senior-aged patients, positive influences on health-related quality of life were observed for educational level, household income, economic activity, alcohol consumption, stress, experience of despair, and basic needs satisfaction. Conversely, negative influences were noted for marital status, types of medical insurance, depressive feelings, and suicidal ideation. Therefore, in order to enhance the HRQOL for middle-aged and senior-aged patients with complex chronic diseases, tailored policies considering individual and age-specific characteristics should be formulated.

This descriptive research study investigated the mediating effect of self-leadership on the relationship between critical thinking and problem solving ability of nursing university students. The data were collected from nursing university students in G city. Korea, from 20 Sep. 2019 through 30 Sep. 2019. General characteristics, critical thinking, problem solving ability and self-leadership were surveyed using structured questionnaires. Statistical analysis was performed using descriptive statistics, ANOVA, and stepwise multiple regression analysis with SPSS/WIN 21.0. The mediating effect of self-leadership on the relationship between critical thinking and problem solving ability was tested using Baron & Kenny's 3-step hierarchical regression analysis. There were positive correlations between problem solving ability and critical thinking(r=.48, p<.001), between problem solving ability and self-leadership(r=.73, p<.001) and between critical thinking and self-leadership(r=.70, p<.001). In addition, self-leadership had a partial mediating effect(Z=6.64 p<.001) on the relationship between critical thinking and problem-solving ability. Therefore, strengthening of self-leadership is necessary to improve the problem-solving ability of nursing university students. Various strategies through regular education courses and extracurricular activities should be prepared for this purpose.

This study compares the history of modern Korean literature written in China with the history of South Korean literature, the history of North Korean literature and the history of national literature, explores aspects of narrative and therefore examines transcultural practice presented in such texts. There have hitherto been approximately 25 works on the history of Korean literature written in China, and 16 of 25 works are on the history of modern Korean literature. Regarding their purpose, the number of pedagogical works outstandingly exceeds the number of research works. In terms of perspective and contents, it can be divided into three categories; one that only embraces the history of South Korean literature, another embracing the history of North Korean literature only and the other embracing the history of South Korean and North Korean literature. This study has selected representative texts from each category and compared recognition and narrative aspects to that of the history of South Korean literature, the history of North Korean literature and the history of Chinese literature. It further examines loci of definitions' transfer and formation as well. As a result, this study reveals valuable understanding of recognition and narration of the history of Korean literature. First, this study offers an introspective attitude, as the history of modern Korean literature accentuates influence of only Western literature, overlooking influence of Chinese literature. Second, this study proposes a new narrative perspective on the history of Unified Korean literature through independent and objective identification of the history of North Korean literature. Last, it emphasizes popularization of literature - aside from pure literary-centrism - and expands possibilities of embracing distinct works relevant to multimedia.

Financial distress can damage stakeholders and even lead to significant social costs. Thus, financial distress prediction is an important issue in macroeconomics. However, most existing studies on building a financial distress prediction model have only considered idiosyncratic risk factors without considering systematic risk factors. In this study, we propose a prediction model that considers both the idiosyncratic risk based on a financial ratio and the systematic risk based on a business cycle. Ultimately, we build several IT artifacts associated with financial ratio and add them to the idiosyncratic risk factors as well as address the imbalanced data problem by using an oversampling technique and synthetic minority oversampling technique (SMOTE) to ensure good performance. When considering systematic risk, our study ensures that each data set consists of both financially distressed companies and financially sound companies in each business cycle phase. We conducted several experiments that change the initial imbalanced sample ratio between the two company groups into a 1:1 sample ratio using SMOTE and compared the prediction results from the individual data set. We also predicted data sets from the subsequent business cycle phase as a test set through a built prediction model that used business contraction phase data sets, and then we compared previous prediction performance and subsequent prediction performance. Thus, our findings can provide insights into making rational decisions for stakeholders that are experiencing an economic crisis.

The purposes of this study was to evaluate the effect of self-fficacy and positive thinking on subjective happiness of nursing students. In this study, 265 data was collected from nursing students of D-city in South Korea from April 4 to 22, 2016. Collected data was analyzed using the SPSS 21.0 Statistics Program. with descriptive statisticsm, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS WIN 21.0 program. There were significant predictors of subjective happiness for nursing students were self efficacy (${\beta}=.023$, p<.01), positive thinking (${\beta}=.610$, p<.001), explaining 48.7% of the variance in subjective happiness. The most important predictors of subjective happiness for nursing students were positive thinking. These findings can be utilized to development of strategies for increasing subjective happiness of nursing students. We suggested a follow-up study that explains the subjective happiness of nursing students by expanding students number.
