Purpose: The purpose of this study was to investigate the mediating effect of self-regulated learning ability on the relationship between experiencing a good class and problem solving ability in nursing college students. Methods: A structured self-report questionnaire was used to measure experiencing a good class, self-regulated learning ability, and problem solving ability. During June, 2019, data were collected from 130 nursing students in D city. Data were analyzed using t-test, One-way ANOVA, Pearson's correlation coefficients, and hierarchical multiple linear regression with SPSS/WIN 23.0. Results: Importance of good class (r=.50, p<.001), satisfaction of good class (r=.42, p<.001), and self-regulated learning ability (r=.71, p<.001) were positively correlated with the problem solving ability of participants. Also, self-regulated learning ability had a partial mediating effect on the relationship between experiencing a good class and problem solving ability. Conclusion: Considering the findings of this study, developing programs that can improve the self-regulated learning ability of nursing students who experience a good class are needed to increase their level of problem solving ability.

The purpose of this study is to find out the influence of MBL Exhibition Class on the Elementary School students' academic achievement, scientific research abilities and affective characters. For the purpose, three classes were sampled in the 5th grade of an elementary school. Among the three classes, two were designated as the comparative classes consisted of 68 students and the other was the experimental class, 33 students. The comparative classes were given lessens according to the content presented in the textbook of 7th Education Curriculum and the experimental class was given re-built lessons with using MBL machines. Before and after giving lessons, students of both classes took a test for science academic achievement. And also the scientific research abilities and affective characters were examined. The conclusions from this study is as follows. First, according to the result of science academic achievement test after giving lessons, the mean of the experimental class was higher than that of the comparative classes meaningfully. Second, scientific research abilities of the experimental class was shown higher than that of the comparative classes meaningfully. Specially, basic research abilities were improved very meaningfully and only hypothesis-building ability was improved among integrated research abilities. Third, it doesn't seem that MBL exhibition class is effective on affective characters(interest, attitudes).

This paper argues that the hard-boiled detective fiction is not a commercialized imitation of the classical detective novels but a revisionist detective fiction. Producing a radically different type of detectives from the traditional ones, the hard-boiled detective fiction provides a new, opposing paradigm of criminality, class, and masculinity to the classical detective fiction. Classical detective novels, through the heroic portrayal of high-class detectives capturing and punishing lower-class criminals, reassure class hierarchy. Hard-boiled detective novels, however, representing the ruling classes as the root of social oppression and political corruption, define the power elite as criminals. Whereas the classical detective fiction displays aristocratic masculinity, the hard-boiled detective fiction embodies working-class masculinity. The classical detective is generally represented as a genteel dilettante solving the mysteries of crimes, in his leisure time, through logical reasoning and scientific techniques. The hard-boiled detective, however, solves crimes by using violence and earns his living from catching criminals. The hard-boiled detective also maintains an absolute independence by keeping a distance from all forms of authority and connection. The representation of hard-boiled detective as a tough, rebellious, independent guy can be interpreted as a reaction to the advent of corporate capitalism and the rise of labor control in the 1920s.

The purpose of this study is to verify the effects of the instructor's communication type on class satisfaction. To this end, a survey was conducted on 204 people taking classes related to beauty design, and regression analysis was conducted on the collected data using SPSS 25.0. It was found that the instructor's communication type had a significant effect on the formation of rapport with learners and class satisfaction. As the instructor's verbal and non-verbal communication positively affects the formation of rapport and enhances class satisfaction, efforts are be needed to improve these aspects. In addition, it can be seen that the instructor's communication type is a variable that positively affects class satisfaction through the formation of rapport. Therefore, instructors need to use appropriate communication types, and the effect of class satisfaction with learners can be enhanced through non-verbal cues, such as exchanging gazes, while having a natural posture, and smiling.

Course evaluation serves as helpful information to improve the quality of college education and improve lectures. This study derived the factors through preceding research and FGI to explore the factors that constitute course evaluation and identified the relative importance and priority of the factors through the Analytic Hierarchy Process (AHP). For this, it derived five factors and 15 evaluation items as follows. To secure expertise and fairness in the factor development of course evaluation, the researcher conducted a questionnaire surveying students and teachers and collected a total of 20 valid data. The weight of each evaluation item was calculated based on the data that had been verified for consistency. The analysis concluded that students rated class content, class method, class operation, class evaluation, and class plan as the critical factors in the order of importance, while teachers evaluated class content, class operation, class method, class evaluation, and class plan as important, in that order. Based on the results of this study, I hope that various analyses and studies will be conducted to improve the efficiency and reliability of course evaluation for the quality management of college education.

In this paper, we focused on the problem of evaluating multi-class classification accuracy and simulation of multiple classifier performance metrics. Multi-class classifiers for sentiment analysis involved many challenges, whereas previous research narrowed to the binary classification model since it provides higher accuracy when dealing with text data. Thus, we take inspiration from the non-linear Support Vector Machine to modify the algorithm by embedding dynamic hyperplanes representing multiple class labels. Then we analyzed the performance of multi-class classifiers using macro-accuracy, micro-accuracy and several other metrics to justify the significance of our algorithm enhancement. Furthermore, we hybridized Enhanced Convolution Neural Network (ECNN) with Dynamic Support Vector Machine (DSVM) to demonstrate the effectiveness and efficiency of the classifier towards multi-class text data. We performed experiments on three hybrid classifiers, which are ECNN with Binary SVM (ECNN-BSVM), and ECNN with linear Multi-Class SVM (ECNN-MCSVM) and our proposed algorithm (ECNNDSVM). Comparative experiments of hybrid algorithms yielded 85.12 % for single metric accuracy; 86.95 % for multiple metrics on average. As for our modified algorithm of the ECNN-DSVM classifier, we reached 98.29 % micro-accuracy results with an f-score value of 98 % at most. For the future direction of this research, we are aiming for hyperplane optimization analysis.
