The purpose of this study was to explore which factors should be considered mainly in operating hybrid learning in which offline and synchronous online environments are integrated in elementary education. Using qualitative data through interview and so on for 8 elementary school teachers with experience in operating hybrid learning, major consideration factors were identified. Before class, it is necessary to increase the level of understanding through concrete guidance or education for what the characteristics of hybrid learning are. The redesign of the environment including hardware and software technology is considered because the foundation was not established properly so that effective operation was difficult. In particular, based on the simultaneity and interactivity between the environments, activities which learners can connect and participate in the two environments should be considered. Further, design strategies to guide the operation of teaching and learning will be developed.

The crossover in fashion refers to the coordination of different items, each with a different atmosphere. In a broad sense, it is the mutual exchange across the existing areas, that is, the creation of a new style by disparate and opposite elements coexisting in a look. This paper studies typical features of the crossover shown in modern fashion based on sub-culture by examining the concept and formation factors of the crossover through social aspects rather than particular art modes to predict the current fashion and suggest a new direction. Crossover fashion appeared in social and cultural environments, has four characteristics : the visual discordance of sexes, the appearance of the lingerie look, the mixture of folk style, and the appearance of the reactionary mode. The crossover, appeared in sub-cultures and diffused into the public, may be considered the creation of a new sense of beauty and a possibility for the future. It is expected to keep expanding ifs range in fashion, since it is an expression of human will to restore liberal sensibility not confined to formality.

The biological wastewater treatment system is known to have an important role in reducing the quantify of enteric virus in water environments. To clarify the roles of activated sludge microbes in decreasing the virus infectivity, the behavior of the virus in bacteria, protozoa, and metazoa was examined by pure or mixed culture system using poliovirus type 1(Lsc, 2ab strain). In the bacterial culture systems, the virus infectivity in the liquid phase decreased by a reversible adsorption of the virus to the bacteria or bacterial flocs. On the other hand, in the protozoa and the metazoa culture systems using T. pyriformis and P. erythrophthalma, respectively, with a variety of bacterial strains as prey, the main virus decrease mechanism of reversible adsorption in early stage was changed to irreversible predation, which was not eluted in this study. The virus decrease was more effective in the P. erythrophthalma culture system, which had high predation and floc forming abilities. However, in the mixed culture system of Z. ramigera and P. erythrophthalma, the more rapid reversible adsorption of virus to Z. ramigera flocs preceded the irreversible predation of P. erythrophthalma.

In recent years, biocontrol of foodborne pathogens has become a concern in the food industry, owing to safety issues. Listeria monocytogenes is one of the foodborne pathogens that causes listeriosis. The major concern in the control of L. monocytogenes is its viability as it can survive in a wide range of environments. The purpose of this study was to isolate lactic acid bacteria with antimicrobial activity, evaluate their applicability as a cheese starter, and evaluate their inhibitory effects on L. monocytogenes. Lactococcus lactis strain with antibacterial activity was isolated from raw milk. The isolated strain was a low acidifier, making it a suitable candidate as an adjunct starter culture. The commercial starter culture TCC-3 was used as a primary starter in this study. Fresh cheese was produced using TCC-3 and L. lactis CAU2013 at a laboratory scale. Growth of L. monocytogenes (5 Log CFU/g) in the cheese inoculated with it was monitored during the storage at 4℃ and 10℃ for 5 days. The count of L. monocytogenes was 1 Log unit lower in the cheese produced using the lactic acid bacteria strain compared to that in the cheese produced using the commercial starter. The use of bacteriocin-producing lactic acid bacteria as a starter culture efficiently inhibited the growth of L. monocytogenes. Therefore, L. lactis can be used as a protective adjunct starter culture for cheese production and can improve the safety of the product leading to an increase in its shelf-life.

In recent years, there are many awareness and demand for digital convergence of the future. In information technology, especially, convergence with other studies such as regional studies, literature and humanities should be needed because information technology is closely related to real life. Culture atlas represents various aspects related to culture visually using points, arcs, and more in the map. Thus, it should be an available tool to survey cultures efficiently in digital environments. For oversea region study, especially Mediterranean region research, we suggest the way to apply electronic culture atlas in this paper. In detail, design and implementation a study on Electronic Culture Atlas for overseas area. Research results for oversea regional studies can be expressed visually by utilizing digital culture map implemented in this paper. Therefore, digital culture atlas should be used as convergence media between information technology and other studies such as regional studies, humanities and so on, tools for oversea regional studies, and exhibition of research results.

In the present study, the protective effects of Bcl-2 over-expression in a suspension culture (without any adaptation) and spent medium (low nutrient and high toxic metabolite conditions) were investigated. In the suspension culture without prior adaptation, the viability of the control cell line fall to 0% by day 7, whereas the Bcl-2 cell line had a viability of 65%. The difference in the viability and viable cell density between the Bcl-2 and control cell lines was more apparent in the suspension culture than the static culture, and became even more apparent on day 6. Fluorescence microscopic counting revealed that the major mechanism of cell death in the control cell line in both the static and suspension cultures was apoptosis. For the Bcl-2 cell lines, necrosis was the major mode of cell death in the static culture, but apoptosis became equally important in the suspension culture. When the NS0 6A1 cell line was cultured in spent medium taken from a 14 day batch culture, the control cell line almost completely lost its viability by day 5, whereas, the Bcl-2 still had a viability of 73%. The viable cell density and viability of the Bcl-2 cell line cultivated in fresh medium were 2.2 and 2.7 fold higher, respectively, than those of the control cultures. However, the viable cell density and viability of the Bcl-2 cultivated in the spent medium were 8.7 and 7.8 fold higher, respectively, than those of the control cultures. Most of the dead cells in the control cell line were apoptotic; whereas, the major cell death mechanisms in the Bcl-2 cell line were necrotic.

This research is implemented to shed new light on the essence of Korean sentiments, aesthetic sense and restructure it in modern ways. In particular, applying the current images of traditional Korean village in Jeonju to neckties is focused on the purpose of globalizing the industrialization of Korean traditional sceneries and Korean image products. Adobe Photoshop CS program was used to develop necktie designs containing the images of the traditional Korean village. To make artworks, the Digital Textile Printing System that is an environment-friendly printing method was used. Moreover, Hanji yarn fabric was adopted for them so as to use Korean materials. The total number of developed designs is eight and neckties for men were made by altering images of the traditional Korean village in modern ways. According to the research results, required are more investment and self-development for proper understandings on our traditional cultural images and their development from now on. Moreover, in my view, customers' desires must be met by comprehending public consciousness, trends and environments to meet customer's desires. Furthermore, higher value-added products must be created by using Hanji yarn and images of traditional Korean villages by distributing high quality designs that will satisfy customers' desires and psychology, producing small quantities of products with various designs and colors.

The COVID-19 pandemic has posed significant community challenges towards higher education around the world. The urgent and unexpected request for full-time university courses to switch over to online teaching was a particular challenge. Online learning and learning imply a certain pedagogical knowledge content (PKC), mainly related to the design and organization for better learning and the creation of unique learning environments using digital technologies. With the help of the present academic paper, we provide some expert opinion on the PKC connected with online learning with the aim of helping non-university professionals (that is, those with lack of online learning experience) navigate these challenging times. Our findings point to the planning of learning activities with certain features, a combination of three types of presence (social, cognitive and facilitative) and the need to adapt the assessment system to new learning requirements. We will conclude by contemplating on how responding to a crisis can improve teaching and learning practices in the post-digital era.

In today's man's domestic environments, the development of furnishings in their various shapes and functions is as complex as human lives. Architecture, Interior, and Furniture, each one of these have the relationship closer and closer to the direct human environments. In this study, by choosing the theme of sitting , the transformation of man's behavioral models would be examined in sociological terms. By viewing the chair as an emblematic objects made for more than just sitting, the chair has revealed the relations of man with his environment since the history of furnishings began. Qualified architects and designers know that chairs are no longer the objects, but the primary subject of furnishings. Through this examination of the emblematic typologies of periodic chairs in the history of the Western culture, in terms of their relationships with politics , religions, monarchies, societies, and etc., the meaning of the designs could be find and which could be the resolutions for the future innovative design. These refound or recreated meanings in the history of design could create another typology for the future reality.
