The systematic research on the Joseon history under Japanese imperialism in the 1920s, including that of the Joseon History Compilation Committee, was one of the stratagems that Japan employed to perpetuate the colonization of Joseon. The 'renovation of national traits', one of the three cultural measures taken by Japanese imperialism after the 1919 Independence Movement, was an attempt to degrade Joseon's nationality as extraneous, dependent, factional, and uncivilized. Against this, Koreans tried to create their own tradition that could prove Joseon's uniqueness and independence. The purpose of their study on ancient history, which became animated in the 1920s, was not to escape from the reality of Joseon into the idealized past, but to construct the history of Korean people anew. In this context, Dangun could refer to cultural identity as the communal origin of the nation, and this invented identity could lead to the healing of the injured subject. An Hwak's attempt was part of this efforts to call out myth as history. He suggests that Joseon's national traits are superior even to the Western civilization in several ways, and his vast plan to set up Joseon's cultural uniqueness and identity as history of universal civilization bore fruit in the History of Joseon Civilization. With cultural research for figuring out Joseon's national peculiarity and identity and historiography for revealing Joseon's national potential, he makes it possible for people to imagine various agents in the Joseon's past as belonging to a single nation with an identical history. Through his study on Joseon, he fought back the Japanese colonial view of history and tried to exalt national consciousness. Asserting independent and rational individuals as agency of civilization and culture though firm in the national perspective, he eventually went a way quite different from that of Japanese history of culture.

Biorenovation is a method that converts existing compounds into new compounds through the enzymatic action of microorganisms. Biorenovation has expected effects such as reducing toxicity of compounds and increasing their activity. In this study, we successfully synthesized Luteolin-7-O-glucoside (L7G) through biorenovation and investigated its inhibitory effect on melanin production in α-Melanocyte stimulating hormone induced B16F10 mouse melanoma cells. We confirmed that Luteolin was toxic at 50, 100 and 200 µM, but our L7G in same concentration was not toxic for B16F10 mouse melanoma cells and also showed significant reduction in melanin production and tyrosinase activity. In addition, while investigating the effect of L7G on factors involved in melanin synthesis through western blotting, we were able to confirm that the MITF and tyrosinase protein synthesis was inhibited in treatment with L7G, however, tyrosinase related protein-1 (TRP-1) and dopachrome tautomerase (TRP-2) expression was not affected. So we derived a conclusion that through biorenovation we could produce compounds like L7G with improved activity and reduced toxicity for possible use as an active ingredient with whitening functionality in cosmetics.It also suggests that the application of biorenovation has potential usefulness in developing anti-inflammatory materials. It also suggests that the application of bio-renovation has potential usefulness in the development of inflammatory material. We applied Biorenovation technology to Distylium racemosum extract (DR) to generate Distylium racemosum biorenovation product (DRB), and investigated the anti-inflammatory properties of DRB in lipopolysaccharide (LPS)-treated RAW264.7 macrophages.

Amid the rapidly changing logistics environment and demand changes in the post-corona-19 era, the importance of the cold chain logistics sector is being highlighted. The scope of cold chain is not limited to food, but is expanding to various fields such as pharmaceuticals, semiconductors, and flowers. The demand on the storage and transportation of corona vaccines is rapidly increasing. The rapid increase in domestic low-temperature facility construction and renovation may lead to the saturation of the cold chain related industry in the future and slow growth. In preparation for this, it is necessary to accumulate infrastructure know-how using IT technologies, and to consider entering into the UN procurement market as a potential niche market, by taking advantage of Korea's recent global status. The demand for cold chain in the UN procurement market is increasing mainly in underdeveloped countries, and it is expected to continue to grow. In this paper, the capabilities of domestic cold chain related companies were analyzed, domestic and overseas cold chain logistics market trends and overseas market entry status were investigated. An in-depth survey was conducted to present strategies for domestic cold chain logistics related companies to enter the UN procurement market.

This study proposes a strategy to attract visitors by analyzing the justification for hosting the 2027 Summer World University Games in Chungcheong, Korea, as well as by assessing the internal and external factors to promote regional development. Using Environmental Analysis as the diagnostic approach, we focus on strength/opportunity (SO), strength/threat (ST), weakness/opportunity (WO), and weakness/threat (WT) analyses. SO analysis show that a matching strategy of mid- to long-term cooperation among the four cities and provinces in Chungcheong and development of local sports by promoting its linkages to science, and industry offer best strategic use-value. ST analysis shows that optimal infrastructure development and establishment of competition management strategies in preparation for non-face-to-face engagement make balanced regional development possible. WO analysis shows the need for rearrangement and renovation of outdated sports facilities, development of programs linked to convergence sports tourism products, efficient and strategic attraction activities, and promoting sustainable development of bed town cities. WT analysis suggests that the imbalance in regional development due to expansion of sports facilities, insufficient cultural contents in tourism, and tourism demand fluctuation are potential problems. Follow-up studies can focus on deeper analysis of the possibility and attractiveness of hosting the Summer World University Games in Chungcheong, Korea using qualitative methods such as focus group interviews and in-depth interviews with stakeholders and local residents.

This paper examines how Korean economy has been asymmetrically changed after economics crises. The three crises during the last three decades, covid19, global financial crisis, and currency crisis, have deteriorated the economic inequalities of Korea in various ways. First, manufacture industry has been affected larger by economic crises, but recovered fast. The shocks in service sector were small but persist longer or were permanent. Second, although the covid19 spreaded out more to the capital area, the negative economic shock was greater in the non-capital region. That is, the crisis in the capital region transferred or amplified to the other region. Third, the inequality between permanent and temporary workers became worse after crises. Fourth, the sluggish small business growth problem became more serious during the covid19. In order to overcome the industrial and labor inequality, it is desirable to government strategy for economic development from focusing on high value-added industry to a balanced growth for all industry and region. To this end, governemt support should be asymmetric. That is, it should focus on indirect support such as regulatory reforms in the high value-added and private-led industries, and, for small business related service sector and non-capital region which have had limited opportunity of renovation and growth, the more active effort of government and government-driven gowth strategy would be desirable.

Biorenovation is a method for converting materials using the enzyme properties of microorganisms. Natural products converted by that method increase physiological activity or reduce cytotoxicity. In this study, we investigated the anti-inflammatory activity of crypsinus hastatus prothallium (CH) and biorenovated CH prothallium (CHB) using RAW 264.7 cells stimulated with lipopolysaccharide (LPS). CHB inhibited the production of nitric oxide, prostaglandin E₂ and cytokines (interleukin-6, interleukin-1β, tumor necrosis factor-α) compared to CH at a concentration of 50-200 ㎍/mL. In addition, CHB concentration of 200 ㎍/mL inhibited the expression of inducible nitric oxide synthase and cyclooxygenase-2 protein by LPS stimulation to the level of the untreated control group. These results indicate that CHB could be a novel anti-inflammatory agent for cosmetic and pharmaceutical ingredients.It also suggests that the application of biorenovation has potential usefulness in developing anti-inflammatory materials.

The meaning of innovative products pursued by pluralized societies is transforming. In the past, the markets were opened up after the products were released through various development strategies based on the needs of development. Recently, however, even the launching process of innovative products is differently operated and strategies with directions completely different from the past are used. In this regard, the paper aims to predict successful markets of innovative products in the future by analyzing the successful strategic cases of innovative products from both the past and the present. The following are the methodology and results of this study. - Conduct a case study and an analysis on which strategies were implemented after the release of successful innovative products in the past. - Conduct a case study and an analysis on the markets and launching trends of innovative products that were successful fairly recently. By reviewing the operation system of innovative products for each time period, it is assumed that startup companies releasing innovative products in the future will engage in the mass production of products through a pre-approval and post-production system, via overseas crowd funding. Moreover, we can expect that systems for partnerships between startups and conglomerates will be prepared in Korea within the near future. If we accurately perceive the operation trends related to the release of innovative products that come into existence by experiencing extreme changes, shortcuts to success will be available for startup companies preparing for such future.

The study primarily aims to examine the characteristics of the transition from natural landscape to modern agricultural landscape on the Daesan plain in Dong-myeon, Changwon-si, in the lower reaches of the Nakdong River. The periods covered in the transition include the late Joseon Dynasty, the early Japanese colonial period, and the late Japanese colonial period. The study concluded the following: It was found that the Daesan Plain used to function as a hydrophilic landscape before it formed into a rural landscape. This is characterized by the various water resources in the Plain, primarily by the Nakdong River, with its back marsh tributaries, the Junam Reservoir and Jucheon. To achieve its recent form, the Daesan Plain was subjected to human trial and error. Through installation of irrigation facilities such as embankments and sluices, the irregularly-shaped wetlands were transformed into large-scale farmlands while the same irrigation facilities underwent constant renovation to permanently stabilize the rural landscape. These processes of transformation were similarly a product of typical colonial expropriation. During the Japanese colonial period, Japanese capitalists initiated the construction of private farms which led to the national land development policy by the Governor-General of Korea. These landscape changes are indicative of resource capitalism depicted by the expansion of agricultural production value by the application of resource capital to undeveloped natural space for economic viability. As a result, the hierarchical structure was magnified resulting to the exacerbation of community and economic structural imbalances which presents an alternative yet related perspective to the evolution of landscapes during the Japanese colonial period. In addition, considering Daesan Plain's vulnerability to changing weather conditions, natural processes have also been a factor to its landscape transformation. Such occurrences endanger the sustainability of the area as when floods inundate cultivated lands and render them unstable, endangering residents, as well as the harvests. In conclusion, the Daesan Plain originally took the form of a hydrophilic landscape and started significantly evolving into a rural landscape since the Japanese colonial period. Human-induced land development and geophysical processes significantly impacted this transformation which also exemplifies the several ways of how undeveloped natural landscapes turn into mechanized and capitalized rural landscapes by colonial resource capitalism and development policies.

This study presents a model for educational planning based on user participatory design for the purposes of curriculum development and educational space innovation. It reviewed previous research and practices related to educational space innovation, educational planning processes, and user participation design and suggested a draft model. This model was applied in the renovation project of an elementary school, and the problems encountered during the application were reflected upon and used to improve the model. The final model comprises four phases. Phase 1 is an initial exploratory phase foruser participation, where educational planners and users form a shared perspective regarding the future of education. Phase 2 is a needs-analysis phase for the transition to future education, which focuses on setting the overall direction of the school-level curriculum. Phase 3 specifies the direction of future school curricula and identifies needs for educational spaces. Finally, Phase 4 focuses on the interaction between educational and space planners. Based on the above discussion, the study discussed the benefits and limitations of this educational planning model for school space innovation.

This research explores the potential of purchased rental housing as a versatile solution for residential development. By focusing on smaller-scale construction compared to large residential complexes, purchased rental housing projects offer benefits such as shorter project durations and enhanced flexibility to accommodate residents' needs. This public-private collaboration extends to community planning, enabling tailored models beyond traditional rental housing frameworks. Currently, purchased rental housing, which is predominantly comprised of multi-unit house, multi-household house, and rowhouses, is in high demand and in short supply in metropolitan areas. Utilizing volumetric modular housing, considerations for module size and transportability are paramount, while advancements in construction methods, particularly prefabrication, offer efficiency and quality benefits. This study proposed three construction techniques to plan modular housing models and enhance construction and demolition efficiency: planning without columns in the middle of the unit, core production using volumetric modular construction methods, and industrialization of construction components alongside dry construction methods. Utilizing these methods, a new construction model for purchase lease housing was presented to address the need for new housing in the context of ageing housing renovation and demand fluctuations. The model comprises 16 units, with sizes ranging from 36 m² to 54 m², and can be applied on sites larger than 600 m² with access to roads wider than 6 m. This promotes cluster-style development, which in turn increases construction efficiency in nearby plots.
