The main purpose of this study was to examine the satisfaction of online classes of undergraduates who have experienced sudden online classes in college because of COVID-19, and to analyze the differences of the satisfaction of online classes depending on colleges. The participants were 1,380 college students. Descriptive statistics, one-way ANOVA, and Post-hoc Scheffé were performed. Undergraduates were highly satisfied with online classes in cultural subjects and major subjects, whereas they showed low satisfaction with appropriateness of the assignment. There were statistically significant differences in online class satisfaction between colleges. Students at the College of Education were highly satisfied with online classes satisfaction, while engineering students were less satisfied with online classes satisfaction. There were statistically significant differences in students engagements between colleges. Regardless of colleges, students displayed low satisfaction in e-class server and teaching and learning infrastructure. These findings suggest that we need to provide autonomous support and make an effective online learning environment such as server expansion and e-class improvement to enhance undergraduates' self-directed learning. We also should come up with effective online classes guidelines.

This study compared the types and creativity level of scientific humors made by general and scientifically-gifted elementary students and their perceptions for educational benefits of making scientific humor. To do this, fifth graders (n=42) at an elementary school and fifth graders (n=38) at a gifted science education institutes in Seoul were selected. Scientific humors made by the students were analyzed and compared according to their types and creativity levels in scientific humor. The students' perceptions for educational benefits of making scientific humor were also analyzed and compared through a questionnaire. Analysis of the results reveal that there were some differences in the incidence rates in 'form' aspects (e.g., generative and descriptive forms) and 'content' aspects (e.g., inclusion of curriculum, scientific discipline, type in use of scientific knowledge, and nature of the situation) between the scientifically-gifted and general elementary students. The scientifically-gifted students also made more fluent, flexible, and original, but similarly useful scientific humors than the general students. Most of general and scientifically-gifted elementary students perceived positively the educational benefits of making scientific humor based on various cognitive and affective aspects.

This study aims to conceptualize characteristics of the Korean traditional dance, and to categorize and analyze the recognition of experience of passing down education of Seungmu(Buddhist Dance), Salpurichum(Exorcism Dance) and Taepyeongmu(Dance of Peace). Dividing into groups of two: an experienced person twenty years or more in the Korean dance and a person who completed the traditional dance three years or more, three groups were selected. We connected the characteristics of the traditional dance experienced in passing down education with the recognition experience in the training courses. Categorizing thematically the process and the recognition of experience in the passing down education program, we attempted mutual group discussion and inductive area analysis on the basis of in-depth interview, tutorial discussion and analysis contents. As a result of this study, first, the characteristics of the Korean traditional dance that graduates of the program by repertory empathize were the experience of the sinmyung(the excess of mirth) and improvisation, the supreme self-controlling beauty and the best beauty of expression. Second, the recognition of experience in the passing down education program runs as follows: Interacting in the centre of the process, new education system for transmission, and formation of social discourse for appreciation. Conclusionally, the experience and the new vision for transmission of passing down education of the traditional dance are required to be based on the appreciation of the rationality of mutual communication and recognition of experience.

The purpose of this study was to examine the understanding and perception of 'community welfare', a domain of social welfare. First of all, we used the Q methodology, a qualitative research, to typology the recognition of community welfare. For the analysis, we have obtained various terms (Q samples) that have been discussed and learned in the community welfare, and examined the types of recognition of these terms. For the analysis, 29 samples of 29 samples were obtained from 29 samples of P samples. As a result of analysis, three types were defined. In other words, emphasizes 'participation of residents', 'building ties', and 'improvement of life quality of residents' is named it "Quality of residents life-Relationship Type". emphasizes 'improvement of quality of life of residents' and 'satisfaction of community needs' and named it "Quality of residents life- Desire for community needs Type". emphasizes 'participation of residents' and 'improvement of quality of life of residents' and named it "Participation of Residents-Quality of Life Type". The respondents' characteristics according to type, it was found that there was a difference in recognition of community welfare by individual characteristics. So, we hope to enhance the usefulness of the hypothesis abductive approach and to extend the study to future quantitative research.

The purpose of this paper is to study on the elements of the Sinmyung and the expression recognition of body movement in Korean dance of college students majoring in musical. The participants were 12 male and female college students in musical major who experienced in dance, song and acting. The program was composed of the experience of the Sinmyung: recognition of sound and dance, breathing and movement in the Korean dance, 8 hours twice a week for four weeks. As a qualitative approach is the discovery of the center of the process, we carried out an inductive analysis of the area on the basis of observation, in-depth interview and student report. The core of this analysis is to attempt to analyze contents concentrating on the recognition exploration of the Sinmyung sentiment and the body expression through sound and breathing. In conclusion, for college students majoring in musical, the expression recognition of the experience of the Sinmyung and the movement in the Korean dance contributes to the improvement of creative thinking through body perception, and the practical use of the capacity of image expression through concentration of sound and breathing. Finally, the results of this research could articulate with the value of body expression and the creative factors of college students majoring in musical.

The clear sky radiance (CSR) is one of the baseline products of the Himawari-8 which was launched on October, 2014. The CSR contributes to numerical weather prediction (NWP) accuracy through the data assimilation; especially water vapor channel CSR has good impact on the forecast in high level atmosphere. The focus of this study is the quality analysis of the CSR of the Himawari-8 geostationary satellite. We used the operational CSR (or clear sky brightness temperature) products in JMA (Japan Meteorological Agency) as observation data; for a background field, we employed the CSR simulated using the Radiative Transfer for TOVS (RTTOV) with the atmospheric state from the global model of KMA (Korea Meteorological Administration). We investigated data characteristics and analyzed observation minus background statistics of each channel with respect to regional and seasonal variability. Overall results for the analysis period showed that the water vapor channels (6.2, 6.9, and $7.3{\mu}m$) had a positive mean bias where as the window channels(10.4, 11.2, and $12.4{\mu}m$) had a negative mean bias. The magnitude of biases and Uncertainty result varied with the regional and the seasonal conditions, thus these should be taken into account when using CSR data. This study is helpful for the pre-processing of Himawari-8/Advanced Himawari Imager (AHI) CSR data assimilation. Furthermore, this study also can contribute to preparing for the utilization of products from the Geo-Kompsat-2A (GK-2A), which will be launched in 2018 by the National Meteorological Satellite Center (NMSC) of KMA.

Background: The purpose of the study was to explore whether the effect of Huanglian-jie-du granule depends on the baseline heart rate variability in patients with Hwa-byung. Methods: We used the supplementary data from a randomized, double-blind, placebo-controlled trial of Huanglian-jie-du granule for Hwa-byung patients. Study drugs were taken orally three times per day for one week. Heart rate variability was measured three times; before the treatment, after the treatment, and month follow-up period. Spearman's rho test was done to explore the role of the baseline heart rate variability to the effect of Huanglian-jie-du granule. Results: Baseline low frequency power of heart rate variability was negatively correlated with the reduction of the insomnia severity index in experimental group (r=-0.493 p=0.02). Also, Huanglian-jie-de granule significantly decreased the low frequency power of heart rate variability in patients with Hwa-byung compared to placebo (mean difference 266 [95% CI: 29~503], p=0.028). In Hwa-byung symptoms, stuffy, pushing up in the chest, and flush of anger were correlated with low frequency power of heart rate variability (p=0.010, p=0.000, and p=0.016, respectively). Conclusions: The effect of the Huanglian-jie-de granule for insomnia seems to be lower when the baseline low frequency power of heart rate variability is higher in Hwa-byung patients. Also, Huanglian-jie-de granule is likely to decrease the sympathetic activity in patients with Hwa-byung. Measurement of heart rate variability may be the useful to understand the state of Hwa-byung patients.

With the appearance of self-driving cars and electric cars, the automobile industry is rapidly changing. In the midst of these changes, HMI studies are becoming more important as to how the driver obtains safety and convenience with controlling the vehicle. This study sought to understand how automobile manufacturers understand the driving situation, and how they define and limit driver interaction. For this, prior studies about HMI were reviewed and 15 participants performed an on-road study to drive vehicles from five manufacturers with using their interfaces. The results of the study confirmed that buttons and switches that are easily controlled by the user while driving were different from manufacturer to manufacturer. And there are some buttons that are more intensively controlled and others that are difficult to control while driving. It was able to derive 'selection and concentration' from Audi's vehicle, 'optimization of the driving ' from BMW's, 'simple and minimize' from Benz's vehicle, 'remove the manual distraction' from the vehicle of Lexus, and 'visual stability' from KIA's vehicle as the distinctive keywords for the HMI. This shows that each manufacturer has a different definition and interpretation of the driver's driving control area. This study has a distinct value in that it has identified the characteristics of vehicle-specific HMI in actual driving conditions, which is not apparent in appearance. It is expected that this research approach can be useful to see differences in interaction through actual driving despite changes in driving environment such as vehicle platooning and self-driving technology.
