This study is a descriptive research to examine the relationship between critical thinking disposition, clinical performance ability, and self-concept of nursing profession according to degree of self-leadership among nursing college students. The data were collected from 165 nursing students in 3rd & 4th grade using self-report questionnaire and analyzed by t-test, ANOVA, Pearson's correlation coefficient, and Multiple Regression. Self-leadership according to general characteristics showed significant differences according to grade, academic achievement, motivation, and major satisfaction. Self-leadership was found to have a positive correlation with critical thinking disposition, clinical performance ability, and self-concept of nursing professional. Analysis of the effects of general characteristics affecting sief-leadership, critical thinking disposition, nursing proFessional selF-concept and clinical performance on selF-leadership showed that they were explained by 49.9%, critical thinking disposition was the most important factor. This suggests that nursing students' self-leadership can be improved effectively by promoting critical thinking disposition. Also in reality, there are many difficulties such as the problems in the system of the majors, but it is necessary to operate a continuous education program to strengthen the self-leadership for the nursing college students by seeking various methods.

The purpose of this study was to identify how patients with chronic kidney disease understand informed consent and related factors for clinical trials. Data from a paper-based survey was collected from July 1, 2017 to April 30, 2018. The subjects for this study were 85 adult patients with chronic kidney disease who were participating in clinical trials. Surveys were conducted by a tool modified from QuIC as designated by Joffe in 2001. The QuIC consists of two parts: objective and subjective cognition. These tools were modified for this study. The average score for the objective understanding (OU) of informed consent for clinical trials was 69.56; the average score for the subjective understanding (SU) of informed consent for clinical trials was 3.28. It was found that health literacy predicted OU (F=27.709, p<.001) while SU was predicted by additional information (F=-3.095, p<.003), question (F=13.603, p<.001), and informed consent (F=-4.833, p<.001). In conclusion, the results of this study indicate that the understanding of informed consent for clinical trials among patients with chronic kidney disease is relatively low. Accordingly, alternative methods that consider each patient's health literacy levels and related factors need to be considered in order to improve their understanding of informed consents during the clinical trial process.

In ornamental crops, the color and shape of flowers are one of the important traits. Generally, flower colors are determined by accumulating pigments such as carotenoids, flavonoids, and betalains. Among them, flavonoids are responsible for broad ranges of colors. Chrysanthemums are one of the most popular ornamental crops in the world, and there have been many efforts to change their flower color. In chrysanthemum flowers, cyanidin-based anthocyanin confers pink or red color, whereas terpenoid-based carotenoids are mainly responsible for yellow and green colors. However, blue colored chrysanthemums do not occur in nature. To date, there have been attempts to obtain blue or violet-colored chrysanthemum flowers through the introduction of a novel gene for accumulating delphinidin-based anthocyanins, while other studies have reported changing endogenous metabolites through the reconstruction of flavonoid biosynthesis. Since various transcription factors are involved in the regulation of flavonoid biosynthesis, it is important to understand not only the structural genes, but also the transcription factors required for the modification of flavonoid-based flower color. Therefore, in this paper, we describe the flavonoid biosynthetic pathway and its regulation, and review previous studies on the change in flower color through modification of flavonoid biosynthesis. This effort could be an important milestone in successfully achieving the modification of chrysanthemum flower color by means of plant biotechnology.

This study proposes an efficient management direction for Korean construction accident cases through a deep learning-based text data classification model. A deep learning model was developed, which categorizes five categories of construction accidents: fall, electric shock, flying object, collapse, and narrowness, which are representative accident types of KOSHA. After initial model tests, the classification accuracy of fall disasters was relatively high, while other types were classified as fall disasters. Through these results, it was analyzed that 1) specific accident-causing behavior, 2) similar sentence structure, and 3) complex accidents corresponding to multiple types affect the results. Two accuracy improvement experiments were then conducted: 1) reclassification, 2) elimination. As a result, the classification performance improved with 185.7% when eliminating complex accidents. Through this, the multicollinearity of complex accidents, including the contents of multiple accident types, was resolved. In conclusion, this study suggests the necessity to independently manage complex accidents while preparing a system to describe the situation of future accidents in detail.

This study investigated a total of 529 integrated science teachers' implementation and changes to apply the curriculum-instruction-assessment. Data was collected through online survey on scientific competencies and skills, teaching-learning and assessment methods, changes of teacher's preparation, topics/materials, teaching-learning, and assessment to apply the curriculum-instruction-assessment as teaching integrated science. The results of the study were as follows: first, in the integrated science class, teachers implemented more on scientific communication and scientific inquiry among scientific core competencies, and analysis and interpretation of data collection and communication among scientific skills. Teachers often taught in lectures and used multiple choice items and short essay for evaluation. Teacher groups with less than 10 years of teaching experience appeared to be less active in teaching scientific core competencies and skills than those with more than 10 years. Second, Teachers have increased more time and efforts to search and to organize various materials in addition to textbooks, and try to integrated concepts in various fields to prepare learning topics and textbooks. Third, even though teachers made little change in implementing the process-oriented assessment, they used instructional strategies to increase student engagement in the integrated science class, restructured the instruction to provide immediate feedback after conducting the assessment. It is necessary to build a system that ensures fairness and credibility of evaluation while respecting the autonomy and professionalism of teachers.

The purpose of this study was to identify factors influencing the transfer of learning for nursing students in clinical practice. This study is a descriptive survey research conducted with 113 nursing students. Self-directed learning, motivation to transfer, and transfer of learning were measured. Data were analyzed by descriptive analysis, independent t-test, and ANOVA. The transfer of learning were significantly different according to the interpersonal relationship (t=10.43, p=.002), the satisfaction of nursing major (t=3.81, p=.006), satisfaction of nursing skills laboratory (t=4.61, p=.004). Transfer of learning had a correlation with self-directed learning, motivation (r=.46, p=<.001), and motivation to transfer (r=.60, p=<.001). In addition, motivation to transfer, the satisfaction of nursing skills laboratory, and learning evaluation were significant predictors of transfer of learning. Finally, in order to increase the transfer of learning for nursing students, nursing instructors need to encourage motivation to transfer, and to apply educational strategies that increase self-directed learning, as well as the satisfaction of the nursing skills laboratory.

This study compared and analyzed the contents of secondary earth science curriculum in Mongolia and South Korea to check the contents of earth science education in both countries and to prepare basic data necessary for future earth science curriculum revisions. The research questions of this study are: first, to understand the changes and current operating conditions of earth science curriculum in both countries, to compare and analyze with other foreign cases, and second, to compare and analyze the contents of earth science and curriculum in both countries. The TIMSS evaluation framework is used to compare and analyze the earth science-related contents included in the science curriculum of middle schools. For analyzing the contents of high school, the contents of NGSS in the United States and the earth science curriculum contents of high schools in South Korea were mixed and the analysis frameworks were created and validated by experts. As a result of the study, countries that follow the Russian-style education system did not organize and operate earth science as an independent science subject, and deal with earth science-related content in the natural geography area of the geography subject. The earth science contents covered in middle school science curriculum in both countries, 18 of the 27 content elements of the TIMSS content analysis framework were matched in Mongolia and 20 in South Korea. In high school curriculum, the contents of earth science in Mongolia were described more briefly and not covered than in South Korea. In particular, the Mongolian geography curriculum dealt with many environmental issues. The emphasis on the operation method of the earth science curriculum in Mongolia and the contents related to the environment can be used as a reference when developing an interdisciplinary integrated curriculum of science and social studies in South Korea.

Purpose: The purpose of this study was to analyze factors affecting the meaning of life in patients on hemodialysis. Methods: The sample consisted of 176 adults diagnosed with chronic kidney disease at hospitals in Seoul and Gyeonggi-do who had been receiving hemodialysis for more than three months. The patients volunteered to participate in the study. Data collection instruments used were the Meaning in Life (ML) scale, Resilience scale, Beck Depression Inventory-II (BDI-II) and Fatigue scale questionnaire. The SAS9.2 version was used for descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation coefficients and stepwise multiple regression. Results: The mean total item score on the meaning of life scale was 133.68 (total score:180), which was low. There was a significant relationship between the ML scale and resilience, depression, and fatigue. Stepwise multiple regression analysis showed that resilience, religion, depression, and fatigue were predictors of the meaning of life. Conclusion: These results indicate a need to develop nursing interventions to increase resilience and reduce depression and fatigue to promote the meaning of life in patients on hemodialysis.
