This study aims to examine the subjects of cultural power of the modernism and post modernism eras, and analyze how the change of power and subjects influenced fashion throughout the history from the microscopic perspective, and thus to explain the social relationship of the fashion phenomenon. The study findings can be summarized as follows. First, as the post modernism era which was being formed centering around Europe that was pursuing Haute Couture and formal masculine suits ended and the post modernism era started, America became the center of the world power, and the American equalitarianism and growing wealth among the general public spread over the world, and as a result, the ready-made clothes were propagated over the world, and various subcultures came to have multi-national tendency in the New Media society. Second, in the modernism era, the high class, whites, males, and the pre-existing powerful class were the subjects of cultural power. Although this changed in the post modernism era, as some of power moved from the high class to the middle class, the economically affluent general public, still the western world, males, and whites held the center of power. However, later, females, youths, the third world nations, and so on emerged as minor power, and when the New Media society started, the structure developed so that everyone can share cultural power.

The purpose of this study is to measure and analyze primary causes of indoor air pollution, including carbon dioxide, minute dust, and total volatile organic compounds, for each room before the beginning of a class through the time of discharge after the end of the class in general classrooms, computer rooms, and science rooms of three newly-established schools that opened in 2006, examine properties of indoor air environment in each room by educational activities at school, and determine effective management schemes; the results of this study can be summarized as follows: 1) As for implications for each item found in the mean for each place, since minute dust (PM10) was more likely to occur in time slots full of students' activities, such as a traveling class and a recess, than in the middle of a class and could be expected fully, it is necessary to make a scheme for cleaning in order to reduce minute dust within a room, for example, by usually using a vacuum cleaner indoors. 2) While carbon dioxide was expected to vary with the differences in the amount of breath between higher-graders and lower-graders in a general classroom but showed insignificant difference by grades, showing differences in pollution by four times at a maximum according to the opening of a window as expected, it is necessary to implement artificial or natural ventilation and take a positive measure, for example, by presenting a concrete ventilation scheme, in order to improve indoor air pollution at a room practice. 3) Total volatile organic compounds were found to exceed the standard by more than twice in general classrooms, science rooms, and computer rooms of the schools because of building materials, furnitures including desks and chairs, panels and boards for environment beautification, and items which could be detected even from students' clothes; while a field directly-reading tool was used, obtaining high reliability for the results, it is necessary to apply an analytical method based on process test separately for actual correct measurement if a significantly great amount of total volatile organic compounds appear as compared with other schools due to measuring expenses and consecutive measurements. 4) Since formaldehyde (HCHO) was generally found to exceed the standard in general classrooms, science rooms, and computer rooms, it is necessary to establish and operate a ventilator during a class in a computer room which requires airtightness and a science room in which an organic compound should be used for a class.

Background and objective: For effective horticultural education, it is required to develop kits for practice. In this study, we developed a horticultural kit for germination that introduces storytelling, characterization, and assembly, and investigated the educational effects of using it to study its educational differentiation and usefulness. Methods: First, we developed a seed germination kit for learning. It consists of three components: the kit main frame for hydroponics, the activity sheet for storytelling, and the instruction manual. It is made into an acrylic assembly in consideration of the ease of delivery for contactless learning. Second, we developed two programs, each using a germination kit for horticultural education (experimental group) and a general germination kit program (control group). At this time, the class consists of pre-questionnaire, the 1st and 2nd classes, observation log writing (total six times for two weeks), the 3rd class, and post-questionnaire. The experimental group and control group were separately executed. Third, the application results were compared and analyzed before and after class. As a quantification questionnaire, the effects before and after class were compared through t-test with a questionnaire on program satisfaction and attitude change toward plants. The quantitative results were analyzed through observation activity sheets and effects before and after the class were analyzed through t-test with quantification and language coding. Results: The effect of horticulture education using the developed kit was estimated by a quantification questionnaire. Both the program satisfaction and the change in attitude toward plants showed high in the experimental group, and this difference was statistically significant (p < .05). As a result of analyzing the observation paper with a qualitative questionnaire, various cognitive and affective expressions appeared in the experimental group as well as the contents of the observation paper. The number of syllables and various qualitative expressions appeared, and these differences were also statistically significant (p < .05). Conclusion: Compared to general germination activities, it was found that the germination activities using storytelling-based horticultural kits would be effective for contactless classes in the post-COVID-19 era and in increasing the educational effect of horticultural activities.

This study aimed to investigate the changes in learner's scientific conceptual formation and academic achievement after a CoRe-based science lesson. For this study, two classes of the 6th grade of elementary school were divided into an experimental class and a comparison one. The students of the experimental class received CoRe-based science lesson and those of the comparison one received general science lesson. Both of the classes studied 'unit 1. A change in the weather', which is a part of content of 6th grade science text book. The results of this study were as follows. First, in the questions of invisible and abstract phenomena, students had misconceptions based on their experience in real life, or did not understand the fundamental causes of that phenomena. But after receiving lessons respectively, experimental class generally showed at a higher rate of understanding the causes of the phenomena than comparison class. Second, CoRe-based science lesson was more effective to improve students' scientific conceptual formation than the general science lesson. Moreover, when two classes were respectively divided into two groups as high and low-level groups according to their pre-test achievement records, the CoRe-based science lesson was more effective to learners of the high-level groups. Third, CoRe-based science lesson was more effective to enhance students' academic achievements than the general science lesson, especially to learners of the low-level groups.

본 연구는 코로나19 이후 불가피하게 진행된 온라인 교양 수업에 대한 교수자의 만족도를 조사, 분석하여 교수자가 인식하는 온라인 교양 수업의 효과성을 알아보고자 한다. 이를 위해 경상남도 C대학의 교양대학에서 2021학년도 1학기 말에 실시한 수업 만족도에 관한 설문조사에 응답한 54명의 교수자를 대상으로 온라인 교양 수업의 전체적인 만족도와 이에 영향을 미칠 만한 변인들에 관해 연구하였다. 그 결과, 교수자는 온라인 교양 수업에 대해 전반적으로 부정적 인식을 갖고 있었다. 전체 만족도와 학습자와의 상호작용 변인에서는 각각 2.80, 2.87의 낮은 만족도를 보였으며, 그 외 요인들에 대해서는 전체 만족도보다 높은 만족도를 보였다. 또한 전체 만족도에 가장 큰 영향을 미치는 요인은 수업에 사용된 플랫폼에 관한 만족도였으며, 통계적으로도 유의미했다. 따라서 교수자의 온라인 교양 수업 만족도에 가장 큰 영향을 미치는 변수인 플랫폼에 교수자는 익숙해질 필요가 있으며, 이를 위해 대학에서는 교수자를 위한 사전 교육이 이루어질 필요가 있다. 본 연구는 일개 대학의 교수자를 대상으로 연구가 진행되었다는 점과 한정된 변수만을 측정하였다는 데에 한계가 있다.
