The purpose of this study was to verify whether the Interactive Cinematherapy Course developed based on discussion is still effective for emotional intelligence and empathic ability, even in a college lecture environment where courses are given online due to COVID-19. The subjects were enrolled in the Interactive Cinematherapy Course and experienced either an online (N=139) or offline (N=212) course before and after COVID-19. To the offline course, students were given structural questions and conducted discussions, whereas the online course students were given feedback via e-mail to substitute discussion. The results were as follows. Compared to the offline courses, students in both online/offline courses commonly showed an increase in "Other's emotion appraisal", "Cognitive Empathy", "Perspective taking", "Fantasy", and "Emphatic Concern". The online course students showed an increase in the "Use of emotion", while offline course students showed an increase in "Self emotion appraisal". This shows that online and offline courses do not have a significant difference in effects. In qualitative research, the lecturer's communication ability and concern helped enhance the effectiveness of the Interactive Cinematherapy Course given online. This implies that communication between the lecturer and students and role of the lecturer are more important than the online environment.

The outcome of the consultation is important to both the counselor and the researcher. Analyzing the trends of research on the results of counseling that have been carried out so far will help to comprehensively structure the results of consultations. The purpose of this research is to analyze research trends in Korea, focusing on research related to the outcomes of counseling published in 「Korean Journal of Counseling」 from 2011 to 2021, which is one of the well-known academic journals in the field of counseling in Korea. This is to explore the direction of future research by navigating the knowledge structure of research. There were 197 studies used for analysis, and the final 339 keyword were extracted during the node extraction process and used for analysis. As a result of extracting potential topics using the LDA algorithm, "Measurement and evaluation of counseling outcomes", "emotions and mediate factors affecting interpersonal relationships", and "career stress and coping strategies" are the main topics. Identifying major topics through trend analysis of counseling performance research contributed to structuring counseling performance. In-depth research on these topics needs to continue thereafter.

In this paper, the need for lifelong education and distance education is increasing due to the decrease of population and the increase of life expectancy. In addition, the popularization and everydayization of education, which combines daily life and learning, is an educational feature. Individuals can more easily access knowledge, and video plays an important role. Video content is the most basic medium that leads to the popularization and daily life of education. With the development of information and communication technology, popularization of media content production and editing technology, anyone can easily create and share. The video education contents business is expected to increase globally through SNS. Especially, the video contents education industry related to flower design is regarded as a suitable content field in an era where environment is essential. In the modern era, characterized by the "one-person household, one-person media" era, the environment of plants protects people from stress by restoring human emotional efficiency, environmental comfort, and stability. In other words, because humans have a preference for nature, plants play an important role for humanity recovery. Against this backdrop, flower design is expected to be a promising industrial sector with high growth, high value added and high job creation effects. In the era of the fourth revolution of the human race, competitive video contents are expected to influence the growth of the future country. will be.

Students' engagement in lessons not only determines the direction and result of the lessons, but also affects academic achievement and continuity of follow-up learning. In order to provide implications related to teaching strategies for encouraging students' engagement in elementary mathematics lessons, this study implemented lessons for middle-low achieving fifth graders using open-ended tasks and analyzed characteristics of students' engagement in the light of the framework descripors developed based on previous research. As a result of the analysis, the students showed behavioral engagement in voluntarily answering teacher's questions or enduring difficulties and performing tasks until the end, emotional engagement in actively expressing their pleasure by clapping, standing up and the feelings with regard to the topics of lessons and the tasks, cognitive engagement in using real-life examples or their prior knowledge to solve the tasks, and social engagement in helping friends, telling their ideas to others and asking for friends' opinions to create collaborative ideas. This result suggested that lessons using open-ended tasks could encourage elementary students' engagement. In addition, this research presented the potential significance of teacher's support and positive feedback to students' responses, teaching methods of group activities and discussions, strategies of presenting tasks such as the board game while implementing the lessons using open-ended tasks.

Depression in old age not only is prevalent but also causes a considerable amount of burden in physical, psychosocial, and economic terms. Intervention, however, is often delayed due to the understanding that considers depressive symptoms as a normal process of aging or signs of physical illnesses. Since the recognition of symptoms often initiate one's help seeking process, a correct identification of symptoms can contribute to early detection and intervention to depression in oneself as well as in others. This study interviewed 104 older adults living in an urban area, and explored their ability to correctly identify depressive symptoms and factors related to identification. The study results show that respondents who were able to correctly identify symptoms of depression were only 14%, and the rest defined the symptoms as social, economic, and other psychological issues. Of the factors in the logistic regression model, age being 75 and over and mass media as source of mental health information affected negatively their ability to correctly identify symptoms; mental health education programs affected positively their ability. Based on these results, it is suggested that such strategies as employing a face-to-face provision of concrete information and counseling can be more effective than delivering information via large-scale lectures. Additionally, a future research deems necessary to conduct an in-depth examination of mental health/illness-related contents on mass media.

The development of artificial intelligence technology changes the social structure and educational environment, and the importance of artificial intelligence capabilities continues to increase. This study was conducted with the purpose of developing a checklist of questions to measure AI capabilities of elementary school students. To achieve the purpose of the study, a Delphi survey was used to analyze literature and develop questions. For literature analysis, two domestic studies, five international studies, and the Ministry of Education's curriculum report were collected through a search. The collected data was analyzed to construct core competency measurement elements. The core competency measurement elements consisted of understanding artificial intelligence (6 elements), artificial intelligence thinking (4 elements), artificial intelligence ethics (4 elements), and artificial intelligence social-emotion (3 elements). Considering the knowledge, skills, and attitudes of the constructed measurement elements, 19 questions were developed. The developed questions were verified through the first Delphi survey, and 7 questions were revised according to the revision opinions. The validity of 19 questions was verified through the second Delphi survey. The checklist items developed in this study are measured by teacher evaluation based on performance and behavioral observations rather than a self-report questionnaire. This has the implication that the measurement results of competency are raised to a reliable level.

The purpose of this study is to explore students' epistemic goals and considerations in designing an experiment task and to investigate how a shift in the students' epistemology affected their argumentation. Four 7th grade students were selected as a focus group. According to the results, when they designed their own experiment, their epistemic goal was 'scientific sense-making' and their epistemic considerations - the perception of the nature of the knowledge product was 'this experiment should explain how something happened', the perception of the justification was 'we need to use our interpretation of the data' and the perception of the audience was 'constructor' - contributed to designing their experiment actively. When students tried to select one argument, their epistemic goal shifted to 'winning a debate', showing 'my experiment is better than the others' with the perception of the audience, 'competitor'. Consequently, students only deprecated the limits of different experiment so that they did not explore the meaning of each experiment design deeply. Eventually, student A's experiment design was selected due to time restrictions. When they elaborated upon their result, their epistemic goal shifted to 'scientific sensemaking', reviewing 'how this experiment design is scientifically valid' through scientific justification - we need justification to make members accept it - acting as 'cooperator'. Consequently, all members engaged in a productive argumentation that led to the development of the group result. This study lays the foundation for future work on understanding students' epistemic goals and considerations to prompt productive argumentation in science classrooms.

Among the Southeast Asian countries, Vietnam had the most cultural exchange with Korea. Through Confusion and Chinese character, which were the common measure for two countries, Korea and Vietnam could communicate and share a sentiment with each other. Two countries showed an enormous interest in each other, and hence they could keep good relationship without official diplomatic relations. During the early 19th century, Korean Ginseng had gained tremendous popularity in Vietnam. Vietnamese believed the stamina of Minh Mang, who had 142 sons and daughters, originated from ginseng. Minh Mang bestowed ginseng on old courtiers for their contribution, which made them more loyal to the king. This tradition was inherited to the future generations, and soldiers who fought with Thai, Cambodia and France also received ginseng for their contribution. In other words, ginseng was the very important key for enforcement of patriotism. Due to the tradition, Korean ginseng has been considered as the premium ginseng in Vietnam. It is presumed that ginseng flew into Vietnam through 4 routes; 1) as an imperial gift from Chinese emperor, 2) by the Vietnamese ambassadors who went to Beijing for a tribute, 3) through private trade and 4) from Ryukyu or Japan, which were the hub of international trade. From 15th to 18th century, ambassadors from Chosun and Vietnam actively interacted in Beijing. Through their interchange, Vietnamese royal family could learn about the value of ginseng. The fact that there were many Shilhak scholars among the ambassadors from Joseon, such as Seo Geojeong and Seo Hosu who had profound knowledge of ginseng proves the theory. It is also possible that reputation of ginseng was already established in Vietnam during Silla period. Ko Byung, an bureaucrat from Tang Dynasty who ruled Vietnam for 10 years in middle 9th century and a friend of Choi Chiwon, might have delivered the knowledge of ginseng to the upper class in Vietnam. This hypothesis, however, should be proven by literatures. Hence, further research about the trace of Korean ginseng in Vietnamese history and literary works still remains to be done.
