This paper investigates the development and aesthetics of Korean political theatre from its quickening period 1920s to democratization era 1990s. Political theatre before 90s developed an antithesis resistant movement toward Korean modern history that had been scattered with suppressing political circumstances such as colonial era and dictatorial government, the movement has powerful activity and social influences. Just like the 20 century political theatre had been quickened under the influence of Marxism at Russia and Germany in 1920s, Korea's political theatre began in socialism theatre movement form around the same time. Proletarian theatre groups had been founded in Japan and Korea, and developed into practical movement with organized connection. However, the political theatre movement in Japanese colonial era was an empty vessel makes great sound but not much accomplishments. Most performance had been canceled or disapproved by suppression or censorship of the Japanese Empire. The political theatre in liberation era was the left drama inherited from Proletarian theatre of the colonial era. Korean Theatre alliance took lead the theatrical world unfold activities based on theatre popularization theory such as 'culture activists' taking a jump up the line and 'independent theatre' peeping into production spot as well as the important event, Independence Movement Day Memorial tournament theatre. Since 1947, US army military government in Korea strongly oppressed the left performances to stop and theatrical movement was ended due to many left theatrical people defection to North Korea. The political theatre in 1960s to 70s the Park regime, developed in dramatically different ways according to orthodox group and group out of power. The political theatre of institutional system handled judgment on sterile people and had indirect political theatre from that took history material and allegory technique because of censorship. In political theatre out of institution, it started outdoor theatre that has modernized traditional performance style and established deep relationship with labor spot and culture movement organizations. Madangguek(Outdoor theatre) is 'Attentive political theatre', satirizing and offending the political and social inconsistencies such as the dictatorial government's oppression and unbalanced distribution, alienation of general people, and foreign powers' pillage sharply as well as laughing at the Establishment with negative characters. The political theatre in 1980s is divided into two categories; political theatre of institutional system and Madangguek. Institutional Political theatre mainly performed in Korea Theatre Festival and the theatre group 'Yeonwoo-Moudae' led political theatre as private theatre company. Madangguek developed into an outdoor theatrical for indoor theatre capturing postcolonial historical view. Yeonwoo-Moudae theatre company produced representative political plays at 80s such as The chronicles of Han's, Birds fly away too, and so on by combining freewheeling play spirit of Madangguek and epic theatre. Political theatre was all the rage since the age of democratization started in 1987 and political materials has been freed from ban. However, political theatre was slowly declined as real socialism was crumbling and postmodernism is becoming the spirit of the times. After 90s, there are no more plays of ideology and propaganda that aim at politicization of theatre. As the age rapidly entered into the age of deideology, political theatre discourse also changed greatly. The concept 'the political' became influential as a new political possibility that stands up to neoliberalism system in the evasion of politics. Rather than reenact political issues, it experiments new political theatre that involves something political by deconstructing and reassigning audience's political sense with provocative forms, staging others and drawing discussion about it.

Background: People's activities have been restricted due to the COVID-19 pandemic. These changes in activity patterns may lead to a decrease in fine particulate matter (PM_2.5) concentrations. Additionally, the level of population exposure to PM_2.5 may be changed. Objectives: This study aimed to analyze the impact of population movement and meteorological factors on the distribution of PM_2.5 concentrations before and after the outbreak of COVID-19. Methods: The study area was Guro-gu in Seoul. The research period was selected as January to March 2020, a period of significant population movement changes caused by COVID-19. The evaluation of the dynamic population was conducted by calculating the absolute difference in population numbers between consecutive hours and comparing them to determine the daily average. Ambient PM_2.5 concentrations were estimated for each grid using ordinary kriging in Python. For the population exposure assessment, the population-weighted average concentration was calculated by determining the indoor to outdoor population for each grid and applying the indoor to outdoor ratio to the ambient PM_2.5 concentration. To assess the factors influencing changes in the ambient PM_2.5 concentration, a statistical analysis was conducted, incorporating population mobility and meteorological factors. Results: Through statistical analysis, the correlation between ambient PM_2.5 concentration and population movement was positive on both weekends and weekdays (r=0.71, r=0.266). The results confirmed that most of the relationships were positive, suggesting that a decrease in human activity can lead to a decrease in PM_2.5 concentrations. In addition, when population-weighted concentration averages were calculated and the exposure level of the population group was compared before and after the COVID-19 outbreak, the proportion of people exceeding the air quality standard decreased by approximately 15.5%. Conclusions: Human activities can impact ambient concentrations of PM_2.5, potentially altering the levels of PM_2.5 exposure in the population.

In order to cultivate the talents acquired in the fourth industrial revolution, developed countries' government are actively engaged in the campaigns encouraging K-12 students to participate in the maker movement. Maker education is regarded as one possible solution based on high tech in the era of the 4th Industrial Revolution, and it is spreading widely along with STEM education. In South Korea, STEAM education was actively conducted nationwide, and since 2017, STEAM and maker education have been linked showing mutual development. However, compared to STEAM education linked to the curriculum, comparison and activity-based research on maker education for teenagers is still insufficient. Therefore, this study aimed to suggest implications for STEAM education and maker education by analyzing the motivation of Korean youth to participate in maker activities. The subjects of this study are high school students who participated in maker education programs in student community for the first time in Korea. In this study, students were classified into engineering-related career group and non-engineering-related career groups based on their career intentions, and the motivation and understanding of participation in maker activities were compared. As a result of the study, male students participated more in maker education community activities than female students, and the engineering-related career group had a higher intention to participate in games, outdoor activities, IT equipment, digital production, and electrical/electronic production activities than the non-engineering-related career group. In addition, in the fields of handicraft/art, home baking, installing, and horticultural agriculture, there was no difference in the intention of participate in the engineering-related career group and the non-engineering-related career group. It was found that the engineering-related career group believed that there was a strong relationship between the maker education community activity, career exploration and future career choice, while the non-engineering-related career group believed that the relationship is less strong. It was also found that the engineering-related career group was participating more actively in the maker activity than the other group.

이 연구는 유아교육실제에서 몸의 교육적 의미를 재인식하기 위한 기초자료 제공을 목적으로 인간공학적 방법을 활용하여 바람직한 몸 교육의 방향에 대한 교훈을 얻고자 하였다. 인간공학 활동분석방법으로 가장 많이 활용되는 OWAS기법을 적용하여 D시에 거주하는 유아를 대상으로 비디오 촬영을 한 후 Snap reading하여 일과 활동내 몸 움직임을 분석하였다. 연구결과에 따르면 유아의 몸 움직임은 활동유형에 따라 다른 양상을 나타내었다. 허리와 팔을 중심으로 한 활동별 움직임은 통계적 유의성을 보이지 않았으며, 다리 활동성을 중심으로 활동 군별로 분석한 결과는 대집단, 소집단, 야외활동 순으로 나타나 전체집단 간 평균분석에서 통계적으로 유의하게 야외활동이 다른 활동보다 월등하게 높게 나타났다. 또 최고 및 최저 움직임을 보인 활동들을 independent t-test를 실시한 결과, 허리의 움직임에서 소집단이 야외활동보다, 다리의 움직임에서 야외활동이 대집단보다 유의하게 활발한 것으로 나타났다. 이 연구의 의의는 인체공학적 활동 분석법을 유아의 몸 움직임 측정에 처음으로 도입한 점과 더불어 이런 적용 결과를 바탕으로 최근 급격히 줄어드는 유아실외활동의 잠재적 위험성에 대해 경각심을 일깨웠다는 데서 찾을 수 있다.
