In this study, data from the 11th year of the Korean Welfare Panel Study (2016), the 12th year (2017), the 13th year (2018), and the 14th year (2019) were used to verify whether drinking problems in adults had an end-to-end effect on depression. The analysis showed that, first, the initial value of depression has a static (+) relationship with the initial value of problem drinking, and a significant relationship with the rate of change in problem drinking. Second, the supply and demand households showed a static relationship with the initial value of depression, the initial value of problem drinking. Third, in the case of people with disabilities, the relationship between the initial value of depression, the initial value of problem drinking, and the amulet (-). Therefore, it was suggested that the development of drinking problem prevention programs and education should be actively carried out in school education before adulthood.

The purpose of this study was to find out the learning effect of applying problem-based learning in esthetic major education at universities and to provide basic data for developing teaching and learning methods that can strengthen competitiveness in esthetic education. Therefore, this study conducted an empirical educational effect analysis by applying PBL classes to 15 students taking oriental therapy, a esthetic major course opened at H University. As a result, the average value of learners' problem-solving ability and cooperative self-efficacy increased after participating in PBL classes, and the effectiveness of PBL teaching and learning methods was confirmed, suggesting effective teaching and learning methods to increase learners' problem-solving ability and cooperative self-efficacy in the field of esthetic.

Purpose: This study aimed to explore the influence of knowledge, problem-solving processes, and self-efficacy on the clinical competency of nursing students in the home health nursing management of diabetes mellitus (DM). Methods: The subjects of this study were 136 nursing students. Data were collected from April 18 to April 29, 2022, and analyzed using the SPSS 23.0 program. Results: The total mean scores of nursing students' knowledge, problem-solving process, self-efficacy, and clinical competency in DM home health nursing management were 71.24, 3.92, 7.47, and 4.09, respectively. Clinical competency was significantly and positively correlated with the problem-solving process (r=.60, p<.001) and self-efficacy (r=.48, p<.001) but not with knowledge (r=.09, p=.311). The problem-solving process was also positively correlated with self-efficacy (r=.41, p<.001). Regression analysis revealed a 41.4% variance in the nursing student's clinical competency with problem-solving process (β=.47, p<.001) and self-efficacy (β=.28, p<.001). Conclusion: The results of this study provide valuable evidence for the development of educational interventions aimed at enhancing the clinical competency of nursing students in relation to home-visit healthcare services for DM management.

The analysis of a certian example and simulations given in the previous sections show that the modified FKA is more stable than the standard FKA without loss of the performance of it. The general analysis of modified FKA's numerical stability is the open problem with more simulations in order to prove the stability of it.

A study of free vibration of axisymmetric circular plates based on Mindlin theory using a pseudospectral method is presented. The analysis is based on Chebyshev polynomials that are widely used in the fluid mechanics research community. Clamped, simply supported and flee boundary conditions are considered, and numerical results are presented for various thickness-to-radius ratios.

In this paper we examine potentials of a spreadsheet program, one of the most widly available software system, as a mathematical optimization modeling tool. For an illustrative example, a shortest path problem is modeled on Lotus-123 for practical use and an implementational framework and a general guide to the spreadsheet modeling of network analysis is provided.

Nurturing students' scientific creativity is considered an important element in science education in Korea. The study aims to explore patterns displayed by well-known scientists in their quest for problem finding. Each case of scientists' course of problem solving is described in terms of historical background, a process of problem finding, and a process of problem solving. There are five patterns from ten scientists which are as follows: Pattern 1 is that scientists find problems from insufficiencies and/or errors from explanation of theories at the time and the related cases are A. Lavoisier, G. Mendel, and J. Watson. Pattern 2 shows that scientists find a problem because of strange phenomena unexplained by theories at the time, and here important case studies are E. Rutherford and W. R$\ddot{o}$ntgen. Pattern 3 demonstrates that scientists find a problem from analogical reasoning between known theories and unknown science phenomena. The cases include S. Carnot and T. Young. Pattern 4 points to the fact that scientists find a problem while they utilize a newly invented experimental instrument. Here, G. Galilei is an important example. Pattern 5 establishes that scientists happen to find a problem while they conduct research projects. The works of M. Faraday and J. Kepler are prominent case studies related to this pattern.

The purpose of this study is to explore the process of inquiry problem finding in high school students' small group free-inquiry. For this purpose, 91 second grade high school students took part in small group free-inquiry. We conducted interviews with students (48 students in 15 groups) who were relatively successful in the inquiry performed for one semester (about 4 months). Based on the results of the interviews, we analyzed the characteristics of the inquiry problem finding through the steps and strategies in the inquiry problem finding process. The main results are as follows: First, in the inquiry problem finding process, steps such as selecting keyword, presenting an inconvenience, presenting a question, and finding an inquiry problem were found, and in particular, the process of selecting the keyword that correspond to the subject of inquiry, such as the material and situation of inquiry, is very important step in inquiry problem finding. Second, the strategies that students used in the process of finding inquiry problem included searching information, review of prior research, sharing of knowledge and experience, linking and extension of knowledge and experience, environmental awareness, expert consultation, discussion of suitability, elaboration, etc. Third, finding an inquiry problem was relatively easy in the inquiry for finding out problems (i.e. inconvenience) in everyday life and investigating ways to solve them. Fourth, the review of prior researches through the internet was useful in the process of selecting keyword and elaboration. Fifth, the factors that students consider when selecting one of several candidate inquiry problems are feasibility, real-life applicability, and economic condition. Sixth, the current affairs had a positive impact on the inquiry problem finding. Based on the above results, we discussed some ways to increase students' inquiry problem finding ability.
