This study explored the case of non-face-to-face classes at colleges initiated in the Corona 19 environment. The scope of this study was to analyze the learning development process of the non-face-to-face class case facing the Corona 19 environment in university classrooms in terms of class and learning content, interaction, assignment activity, and teaching-learning activities. It was conducted for first-year students at H University's Early Childhood Education Department of Startup Basic Course. Study results found that, first, interest in entrepreneurship increased as learning content. Second, as a result of exploring the teaching and learning process, there is no significant difference in understanding the content or achieving learning goals. Third, the most regrettable thing about non-face-to-face teaching-learning is the lack of interaction activities. Fourth, the students finished by adapting to the new non-face-to-face teaching-learning environment. In the future, a non-face-to-face environment platform should be established, and studies that can deal with new perspectives and approaches, such as an educational interaction system including online and offline, should be continued.

This study identifies factors of Hanbok-trippers - a term for people who dress in Hanbok(Korean traditional costume) while going on a trip - who converge on Gyeongbokgung Palace by determining the characteristics of class, places to visit and preferred places. This study interprets the voluntary hobby activities of Hanbok-trippers from a viewpoint of a landscape prosumer and the meaning of the urban landscape. As a result of in-depth interviews, on-site survey, and observation surveys focused on Hanbok-trippers, there were various levels of participants. They are classified into three groups - leading group, entry group, temporary-experience group - according to their cognitions, types of Hanbok use, activities, etc. The leading group and entry group are a voluntary hobbyist class due to the ongoing tendencies of their participation. There are differences in the purpose and factors of visiting Gyeongbokgung Palace as a place for a Hanbok-trip. The leading group visited Gyeongbokgung Palace for cultural activities, regular get-together, public relations, and as a gathering place to go neighboring destinations. In this case, the main factors of the visit are the traditional landscape, convenient transportation, chances for traditional culture exhibitions and events in Gyeongbokgung Palace and its neighborhood. The entry group visits Gyeongbokgung Palace because of its traditional landscape and cultural activities nearby. The traditional landscape and many Hanbok-trippers are main factors of visiting Gyeongbokgung Palace for the Temporary-experience group. This study found that Gyeongbokgung Palace has a new sense of place of 'Introductory course of Hanbok-trip', 'Hanbok Playground' because temporary-experience group visits there to experience a Hanbok-trip for the first time. Hanbok-trippers consume places and landscape in actual places offline, producing a new landscape at the same time, and has the characteristics of a 'landscape prosumer' by producing landscape images online through their own personal or social media. Their colorful and voluntary movements contribute to the dynamism of the urban landscape and can become a new cultural asset for the city. The voluntary hobbyist class can be considered a new type of participants in bottom-up planning such as urban regeneration and place marketing. This study has significance in that it conceptualized the 'landscape prosumer' through the voluntary hobbyist class of Hanbok-trippers with the concept of the 'prosumer' that has been studied only in the consumer studies and marketing fields, and has identified the significance of the urban landscape.

We present two data-driven modeling methods, partial least square (PLS) and artificial neural network (ANN), to predict the major operating and performance variables of a polymer electrolyte membrane (PEM) fuel cell stack. PLS and ANN models were constructed using the experimental data obtained from the testing of a 30 kW-class PEM fuel cell stack, and then were compared with each other in terms of their prediction and computational performances. To reduce the complexity of the models, we combined a variables importance on PLS projection (VIP) as a variable selection method into the modeling procedure in which the predictor variables are selected from a set of input operation variables. The modeling results showed that the ANN models outperformed the PLS models in predicting the average cell voltage and cathode outlet temperature of the fuel cell stack. However, the PLS models also offered satisfactory prediction performances although they can only capture linear correlations between the predictor and output variables. Depending on the degree of modeling accuracy and speed, both ANN and PLS models can be employed for performance predictions, offline and online optimizations, controls, and fault diagnoses in the field of PEM fuel cell designs and operations.

The purpose of this study is to verify the effects of partial-cyber and full-cyber lectures and explore directions for improvement. This study compared the mean scores of course evaluation for traditional face-to-face lectures, partial-cyber lectures of blended instruction, and full-cyber lectures. Also, this study interviewed instructors of full-cyber lectures to investigate the ways to enhance the lecture quality. The findings suggest that the course evaluation scores for full-cyber university were consistently lower than those for other types of lectures for four semesters between the years of 2011 and 2012. Results also showed that mean scores of partial-cyber lectures were the same as those of face-to-face lectures. After all, class satisfaction in full-cyber courses that learning occurs in cyber space was the lowest. Instructors who taught full-cyber lectures proposed that enrollment should not be within 60 students and professional assistance should be provided for lectures exceeding 60 students. Finally, they suggested content updates through a collaborative system with professionals, instructors' efforts to enhance interaction in both online and offline contexts, and learning quantity rationalization.

This study investigated the effects of the HTE creative education program, which applies blended learning methodology as a convergence class strategy between offline and online, on middle school students' creative problem solving capability. As a result of applying for five creative education practice programs in the classroom, it turned out that there was a statistically significant difference (p < .05) in the case of idea manipulation, visualization, comparison, idea generation, and deliberation, subordinate constructs of creative problem solving capability. Also, the program turned out to be positively effective, with a 0.14 point improvement in the pre and post-means of all middle school students, showing from 3.65 to 3.79 points, and 72% of middle school students who participated in the program were satisfied, and 68% were interested. According to the results, HTE creative education programs using blended learning turned out to be effective as a customized methodology in the COVID-19 situation and the era of the 4th Industrial Revolution, where various creative talents are needed. Therefore, the need for the development of creative education programs on various related topics and teacher training for teaching and learning methodologies of blended learning.
