This study aimed to understand and analyze the learners' class satisfaction and the effectiveness of synchronous online classes after COVID-19. A total of 188 learners participated in the survey conducted at the end of the Fall Semester 2020 at C University located Gyeongsangnam-do. Findings revealed that learners' satisfaction with the synchronous online classes was relatively low, and the learners had negative perception of that. Learning content have the biggest effect on the learners' class satisfaction. Next came class management and the online learning platform. Therefore, instructors need to organize learning content effectively and enhance learners' understanding considering the most influential variable, learning content so that learners are satisfied with the synchronous online classes. Also, instructors should make it possible for learners to get familiar with the online learning platform and use it without any problems through systematic and faithful class design for effective learning in unfamiliar online learning environment. In addition, instructors need to know learners' needs and difficulties and plan their synchronous online classes. This study has limitations in that it was conducted only at one college and the limited number of variables was measured.

Background: Abnormal activation of matrix metalloproteinases (MMPs) plays an important role in UV-induced wrinkle formation, which is a major dermatological problem. This formation occurs due to the degeneration of the extracellular matrix (ECM). In this study, we investigated the cutaneous photoprotective effects of Ultraflo L treated ginseng leaf (UTGL) in hairless mice. Methods: SKH-1 hairless mice (6 weeks of age) were randomly divided into four groups (8 mice/group). UTGL formulation was applied topically to the skin of the mice for 10 weeks. The normal control group received nonvehicle and was not irradiated with UVB. The UV control (UVB) group received nonvehicle and was exposed to gradient-UVB irradiation. The groups (GA) receiving topical application of UTGL formulation were subjected to gradient-UVB irradiation on $0.5mg/cm^2$ [GA-low (GA-L)] and $1.0mg/cm^2$ [(GA-high (GA-H)] of dorsal skin area, respectively. Results: We found that topical treatment with UTGL attenuated UVB-induced epidermal thickness and impairment of skin barrier function. Additionally, UTGL suppressed the expression of MMP-2, -3, and -13 induced by UVB irradiation. Our results show that topical application of UTGL protects the skin against UVB-induced damage in hairless mice and suggest that UTGL can act as a potential agent for preventing and/or treating UVB-induced photoaging. Conclusion: UTGL possesses sunscreen properties and may exhibit photochemoprotective activities inside the skin of mice. Therefore, UTGL could be used as a potential therapeutic agent to protect the skin against UVB-induced photoaging.

The purpose of this study was to develop science essay writing activities for developing elementary pre-service teacher's scientific thinking ability and scientific emotion and to analyze its effects. For the study, 60 first grade students attending teacher training institutes in the G region of Korea were selected. All 60 elementary pre-service teachers were students who selected a liberal arts lecture related to 'science inquiry'. As a result of the study, we confirmed that the preliminary teacher uses the scientific method of 'induction' in the article related to scientific thinking and the description related to the past time, agency, and purpose of the story is included in the essay related to scientific emotion. In addition, it was confirmed that elementary school teachers' writing ability was improved as the writing was repeated, and that the image of 'science' changed positively in many areas. This study suggests that a various and interesting scientific inquiry activities are needed to improve the science writing skills.

This study aims to organize the basic concepts for the technical development of holograms as a medium to go beyond the range of everyday and instrumental use to artistic and conceptual meanings, and to study various forms of expression that can be used as directing tools. As an example of the researcher's directing works and projects using the similar hologram expression form, which is called the Pepper's Ghost method or the floating hologram method as the current stage utilization technology, the technical limitations of the hologram depend on the goal of directing within the scope permitted under the theater of stage art. By analyzing the correlation between holography and stage elements and the timing and point of view to obtain emotional responses from the audience, and presenting stage alternatives, more active motivation is given to the stage expression of holograms leading to future technology development and a new field of future performing arts. I want to prepare the theoretical foundation of aesthetics.

Arguably, the term "Learning Organisation" (LO) was coined in the 1970's, in the organisational learning context, by Chris Argyris. Certainly it has been around for many years. But it achieved new heights of popularity after the publication of Peter Senge's book "The Fifth Discipline the Art and Practice of the Learning Organisation". Now every respectable Government Agency and major company feels obliged to call themselves a L0. A review of the academic literature and organisation documents show many different concepts being described. Indeed, it seems that some organisations claiming to be a L0 have no clear idea of what they mean by the concept. This paper seeks to go behind the confusion to see whether there is still value for serious practitioners to continue using this concept, or whether it is now such a hackneyed phrase that more precise concepts are desirable. The Literature relating to the L0 is vast and it is beyond the scope of a conference presentation to give a comprehensive literature review. Instead, the paper gives an overview of the broad groups using the term and summarises their similarities and differences. It then reviews the key concepts in Senge's work in the light of this cacophony. The paper concludes that the diversity of definitions render the term "Learning Organisation" virtually meaningless. unless it is accompanied by a specific definition. The paper also concludes that the central tenet of Senge's work, which played a major role in popularising the concept, has been largely overlooked by the many organisations claiming this proud title "A Learning Organisation." It is argued that Senge's contribution to the literature in this field, the centrality of systems thinking to effective organisation learning remains a little understood, but critical insight.

This article examines how the Chinese government blocks the inflow of undesirable information, focusing on the technical aspect of the control mechanism. Unlike Cuba and North Korea, which regulate the whole Internet, China uses both state-of-the-art technological supervision and labor-intensive physical control due to economic reasons in order to prepare for actors who can threaten the Communist party. The Chinese government will not overlook the inflow of information which can be the link between demonstrations and democratization. This is because stronger protests utilizing information technology will trigger the Chinese government's flexible control based on large scale violation and technology. In this article, we first review the concept of universal internet control involved in internet regulation in nations, and then focus on China's internet censorship and its regulatory control from the '90s to the present. Finally, we analyze how the Chinese government actively controls the internet access by utilizing the relationship dynamics between the central and local governments, depending on protest issue. This thesis will assume that it is difficult for China to become democratized due to its information interception, and search how the government manages the internet.

The purpose of this study was to realize and apply Taekwondo's technology and the fact that actors on stage and screen have much in common. In the meantime, there have been many prior studies on the development of the theoretical field. However, there is a slight lack of practical development and development plans, and it is time to improve. This seems to be a lack of practical experience leading to the creation of physical images. In that sense, I think that it should be supported by the complement of concrete and detailed research that seeks to make changes in open technology significantly. Considering this situation, it is necessary to further develop the practical field in parallel with the theoretical field. Therefore, I suggested the principle of physical behavior through Taekwondo technology and the development of acting skill. The performance training using these taekwondo techniques is meaningful research.

Objectives: Waste treatment by incineration is gradually increasing as the emission of harmful substances has decreased owing to developments in incineration technology. However, residents living near incinerators continue to express anxiety regarding the effects on their health. Therefore, we attempted to summarize the health impact of incinerators by comprehensively reviewing the recently reported literature. Methods: Sixty-two epidemiological research papers related to incineration and health effects were selected from the Google Scholar database and analyzed (from between January 2001 and December 2019). Results: When compared to older incinerators, newer incinerators established after 2000 are considered relatively safe in terms of health effects. Nevertheless, there have been some studies that have linked them to various diseases, such as malignant tumors including soft tissue cancer and non-Hodgkin's lymphoma, reproductive disorders, respiratory diseases, and more. In addition, incinerator workers and local residents are considered to be exposed to dioxins and some heavy metals from the incinerator. Since most studies included subjects exposed to older incinerators, it is difficult to apply these results to the health impact assessment of new incinerators. However, it is not appropriate to conclude that new incinerators made with state-of-the-art technology are safe, as chronic environmental diseases caused by hazardous substances tend to appear only after prolonged exposure. Conclusions: In terms of environmental health, it is necessary to continuously monitor the health effects of incinerators. Also, there is a need to develop a research methodology that can minimize various confounders in incineration-related epidemiological study.
