The main purpose of this study is to investigate the impact of COVID-19 risk perception on the operational activities and performance of incubator tenant companies during the early stages of the COVID-19 outbreak. The primary variables considered for the operational activities of incubator tenant companies include financial management, research and development, marketing, and downsizing. Financial and non-financial performance are the key variables for business performance. The research findings indicate that COVID-19 risk perception has a significant impact only on downsizing, but it does not significantly affect financial management, research and development, or marketing. Additionally, COVID-19 risk perception has a significantly negative impact on both financial and non-financial performance. Financial management and marketing significantly influence financial performance, while research and development and downsizing do not seem to have a significant impact on financial performance. Conversely, research and development, as well as marketing activities, significantly impact non-financial performance, while financial management and downsizing lack a significant influence on non-financial performance. Finally, when examining incubator tenant companies categorized into early-stage, leap-stage, and growth-stage companies, it was observed that only marketing activities have a common and significant impact on non-financial performance across all three types of companies.

The purpose of this study was to verify the antifungal properties of various herbal medicines belonging to the Ranunculaceae family and to find an extraction method effective in inhibiting fungal growth. When antifungal activity was measured in a liquid medium with extracts obtained by either hot water extraction or organic solvent extraction of the herbal medicines Clematis apiifolia, Coptis chinensis, and Pusatilla chinensis, effective results were obtained from the chloroform extract. In addition, fungal growth inhibition experiments were performed on unicellular fungi, Candida albicans, Candida tropicalis, and Candida lusitaniae, and on filamentous fungi, such as Pythium ultimum, Aspergillus fumigatus, and Fusarium oxysporum, using disk diffusion experiments on solid media. It was confirmed that P. chinensis extract has excellent antifungal properties against Candida spp. and C. apiifolia extract against filamentous mold. Finally, GC-MS analysis was performed to explore the useful antifungal substances present in the extract. As a result of the study, thurbergenone from C. apiifolia and 16-hydroxycleroda-3, 13(14)-dien-15, 16-olide (16-HCDO) from C. chinensis were confirmed as antifungal candidates. In conclusion, it was confirmed that C. apiifolia, C. chinensis, and P. chinensis have antifungal activity against various fungi, and in GC-MS analysis, all herbal medicines were confirmed to have different antifungal candidates. These results indicate that the Ranunculaceae family has evolved in several directions for fungal resistance traits.

This study analyzes the effects of firms' technology innovation(patent applications) on employment(number of workers and proportion of high-skilled workers) and corporate performance(sales per worker), while considering the two-way causal relationships between these variables. We used the three-stage least squares(3SLS) estimation to examine system of equations in which the dependent variables affect each other with a two-year lag wherever relevant, and applied it to firm-level panel data of Korean manufacturers with 100 or more workers. Our data covered the period of 2005-2017. Exogenous variables, such as firms' managerial and other characteristics, were controlled as explanatory variables. The identification variables for each equation included firms' R&D intensity, labor cost per worker(or operation of firms' own R&D center), and investment on worker training. We find that firms' patent applications increased number of workers, proportion of high-skilled workers, and sales per worker; the causal relationships in the opposite direction were also significant. Evidently, firms' technology innovation is critical to the growth and quality improvement of employment as well as sustainable corporate growth.

Excellent FinTech firms create value by finding customer needs or addressing customer problems to provide customers with differentiated solutions through information technologies and organizational innovation capability. Accordingly, the survival and growth of FinTech firms rely on the innovation performance for solving customer problems. This study assumes that IT relatedness and entrepreneurial culture play a mediating role in the relationship between service orientation and innovation performance. To examine it, designed and demonstrated is a structural model from the perspective of dynamic organizational capability. The results show that IT relatedness and entrepreneurial culture play a mediating role between service orientation and innovation performance. Although IT relatedness and entrepreneurial culture were partial mediators in each divided model, the integration model showed there was no direct effect of service orientation on innovation performance. The practical implication is that FinTech companies need to understand customer problems accurately, set up appropriate service goals and align all strategies to achieve them. With these strategic alignments, higher innovation performance can be achieved by enabling IT resources and capabilities to be actively utilized in all functions of the organization and institutionalizing the entrepreneurial culture.

This study is a qualitative case study on the experience of an on-site, audience-participatory educational play conducted by four college students majoring in theater under the title 'Hooni and Choroki' for 7-year-old kindergarten students about to enter elementary school. The core theme of the play is to help relieve anxiety about school life before entering elementary school and to communicate smoothly with peers. To this end, college students participate in scenario planning, kindergarten recruitment, and 40-minute training at three kindergartens. He even conducted theatrical performances. As a result of the study, the key components of 'another growth in my life', 'improvement of happiness through meeting children', and 'new challenge toward dreams' were derived. The greatest significance of this study is that the audience-participatory educational theater experience allowed college students to practice sharing the results of their learning with someone else, and through this practice of sharing learning, they were able to realize their somewhat vague career paths and dreams. It was an opportunity that allowed me to experience 'improved confidence' and 'a resonance in my heart' so that I could set a direction. We hope that future educational theater with audience participation will be widely implemented in various aspects.

Graphene oxide (GO), known for its high stiffness, thermal conductivity, and electrical conductivity, is being utilized as a reinforcement in nanocomposite materials. This study evaluates the mechanical properties of epoxy nanocomposites incorporating GO and edge modified GO (E-GO), which has hydroxyl groups substituted only on its edges. GO/E-GO was uniformly dispersed in epoxy resin using ultrasonic dispersion, and mechanical properties were assessed through tensile testing. The results showed that the addition of nanoparticles increased both tensile strength and toughness. The tensile strength of the epoxy without nanoparticles was 74.4 MPa, while the highest tensile strength of 90.7 MPa was observed with 0.3 wt% E-GO. Additionally, the modulus increased from 2.55 GPa to 3.53 GPa with the addition of nanoparticles. Field emission scanning electron microscopy of the fracture surface revealed that the growth of cracks was impeded by the nanoparticles, preventing complete fracture and causing the cracks to split in multiple directions. E-GO, with surface treatment only on the edges, exhibited higher mechanical properties than GO due to its superior dispersion and surface treatment effects. These results highlight the importance of nanoparticle surface treatment in developing high-performance nanocomposite materials.

This paper analyzes a case of successful faculty entrepreneurship through a coupled process of open innovation in a university context, using the core competency theory perspective. Initially, the current state of faculty entrepreneurship is examined, and the effects of interdisciplinary coupled processes of open innovation are explored, focusing on the case of 'Omotion Inc.,' a startup utilizing generative AI technology for hyper-realistic 3D virtual human experiences. The research methodology involves in-depth interviews with Omotion Inc.'s co-founders, technology commercialization professionals, and experts in the field, followed by analysis based on foundational theories. Applying the core competency theory, this paper scrutinizes the process of integrating diverse expertise and technologies from various academic disciplines. The analysis goes beyond the limitations of faculty entrepreneurship confined to a single technology-centric research domain. Instead, it explores the possibilities of enhancement and value creation through coupled processes, providing practical implications for the university entrepreneurial ecosystem. The aim is to extend the traditional roles of education and research within the university, presenting a role in economic value creation beyond the boundaries of conventional faculty entrepreneurship. Through the collaboration of two faculty members, this study showcases the creation of novel technology and business models. It establishes that successful coupled processes of open innovation in faculty entrepreneurship, from a core competency theory perspective, require the entrepreneurial firm to possess (1) entrepreneurial capabilities, (2) technological capabilities, and (3) networking capabilities. The implications of this research highlight the positive impact of coupled processes of open innovation in faculty entrepreneurship, as evidenced by the Omotion Inc. case, offering guidance on entrepreneurial directions for university members preparing for entrepreneurship.

Purpose of study: Recognizing the importance of securing professionalism in church education in the context of the serious problem of church eucation in the Korean church today, this study aims to reveal the problems of current church education and suggest alternatives for solving the problems. Research content and method: The Korean church is facing crises. One of the crises is the decline in church membership and worship attendance. Another, more fundamental problem is the crisis of church education, where the number of students in Sunday schools is plummeting, and many young people are leaving the church. Many of them are questioning the quality of church education leaders. The decline and demise of Sunday schools does not bode well for the future of the Korean church. What the church needs to do to address these issues is to build up educational professionals. Leadership and professionalism are critical issues. Until now, the needs of church education in the Korean church have relied on dedication and life mission rather than professionalism. And these criteria were enough. It has been 34 years since the October 1989 resolution of the General Assembly of the Christian Church in Korea to establish a system of educators. However, little progress has been made and the system has not been changed to a system of educators. One of the ways to solve this problem is for the Korean church to prepare for the future of the Korean church by utilizing educators for church growth and the restoration of Sunday schools. Conclusions and Suggestions: For the function, mission, and purpose of the church, the system of educators is requested to be established in the Korean church as soon as possible to fulfill the professional church education and educational pastoral mission. In response to this call, current Korean church education needs to change and innovate. The direction of innovation is professional education, which means that there is a need and urgency for professional educators qs church education leaders.
