This study analyzed how K-MOOC was used and identify the academic achievements in higher education. The participants who completed the survey questionnaire were composed of 379 students who were in curriculum-related extra-curriculum using K-MOOC. Results show that the participation rate in individual learning activities was high, thus indicating the activities were perceived positively. In addition, students perceived positively their academic achievements of receiving, valuing, and responding in affective area, as well as synthesis and evaluation of knowledge in cognitive area. Students were also satisfied that they had no psychological burden to the credit of the course and they could take a course from another college. By contrast, platform instability, too much online content, and tedious activities in the lessons were perceived negatively. Nonetheless, the group assessment results suggested that the students taking a course related to their major had further engagement in discussions, and their academic achievement was higher. Based on the foregoing findings, the study proposed developing a subject matter with various theme, utilization plans, interaction reinforcement, and quality management by supporting instructional design strategies in order to expand the use of K-MOOC both as a general education and a major curriculum. The results obtained in this study represent baseline data that may assist in the decision making for university system and operation plan.

Project-based learning (PBL) encourages self-autonomy and connects learning and real-life skills in the learning process. The purpose of the current study is to investigate students' life skills and self-regulated learning strategies in a PBL curriculum in order to examine how the proposed benefits of PBL are manifested in students' self-awareness of their learning process. Twenty-three students in a university in Korea participated in a 3-credit, 4-week, intensive PBL course for English majors. During the PBL course, students were asked to self-assess their life skills related to time management, cooperation, standard of work, and participation three times. In addition to the self-assessment, students kept reflection journals to keep track of their use of self-regulated learning strategies and progress which were also submitted three times. Based on the analysis of self-assessment and self-reflection, the results showed that students' perception of cooperation improved significantly during PBL. Furthermore, it was found that students also progressed through the three phases of self-regulated learning. Implications on suggesting on the use of PBL to encourage the development of life skills and self-regulated learning strategies are provided.

COVID-19 has had a detrimental effect on urban vibrancy, particularly in urban commercial districts. Against this backdrop, the goal of this study is to examine the changes in social and economic vitality in Seoul's commercial area before and after the COVID-19 outbreak, and to identify influential factors for the changes in vitality using multinomial logistic analysis. The following are the key findings derived from the study. First, an examination of the changes in the vitality of commercial districts by type revealed that the decline in economic vitality was greater than the decline in social vitality. Second, the greater the residential ratio, the less harmful the impact of COVID-19 on urban vibrancy. Third, unlike other types of commercial districts, traditional markets had a minor increase in credit card sales even though the floating population fell during the COVID-19 pandemic. Fourth, the accessibility of the subway did not play a positive role in reversing the decline in social and economic vitality caused by the pandemic in the commercial district of Seoul; rather, the accessibility of private automobiles contributed to the increase in social and economic vitality. These results imply that the development and activation of commercial areas accessible by non-motorized modes in the residential neighborhood are becoming crucial in the post pandemic era.

Unification means the change of the economic system from 'Planned Economy' of the North Korea to 'Market Economy' of the South Korea. Therefore, it may cause confusions and difficulties for North Koreans who have been under planned economy for ages. So, we need to take the perspective of behavioral economics for the effective education. First of all, it is about overall finance, which contains the record of financial transactions, effect of inflation, investors' bounded rationality, and choice difficulty of financial products. Second, it is about borrowings, which includes the credit management, interest rate of difference among financial institutions. Third, it is about investment on financial products, which includes the effect of cost on returns, difference between compound interest and simple interest, trade-off between expected return and risk, market and non-market risks, the importance of diversification, and passive & aggressive investments.

This study aimed to suggest measures expand career-related elective subjects in the high schools through a case of establishing and utilizing a learning space for hands-on home economics classroom activities. Upon the trend reviews of elective subjects in the high school and literature reviews on the educational outcomes from home economics classrooms, a case of career-related elective subject by establishment of learning space related to home economics was proposed in two high schools in Seoul. The results are as follows: First, the trend in 2020 showed that selecting a home economics course as a career-related subject depends on school situations. The results of the survey at schools show that the utilization rate of hands-on learning space for home economics was high with high preference among students, but schools implicitly guided students to select courses that are related to preparation for university entrance. Second, reductions of class hours and decreased likelihood to offer courses in home economics in general high schools would influence the recruitment of teachers, which may ultimately result in a threat to the subject. However, through career-related activities, students may develop positive perception of the subject of home economics and consequently select the subject. Therefore, it is necessary to open and promote multiple elective courses related to home economics for the survival of subject of home economics.

The survival period according to technological capability was analyzed for about 22,500 innovative SMEs in the service industry. The survival period was defined as the occurrence of overdue and default, and the technological capability was divided into two clusters. As a result of estimating the survival period according to technological capability through Kaplan-Meier analysis, it was confirmed that the estimated survival period of T1-T4 grade service innovative SMEs was significantly greater in both overdue and default. As a result of the analysis of the Cox proportional hazard model applying the control variable, it was confirmed that the higher technological capability, the lower the risk in the group of start-up companies. However, in the group of non-start-up companies the technological capability did not significantly affect the survival period, and the influence of the variables related to the size of the company was found to increase. Therefore, the technological capability is meaningful as additional information that has a significant effect on the survival period of innovative SMEs in the start-up companies group of service industry. In addition, it was concluded that it is necessary to reflect the technological capability when establishing the SME support and promotion policy of the start-up companies group in the service industry.
