  • Wooden cultural heritage are exposed to the external environment as they and there are many difficulties in conservation due to their location and size. Among them, biological damage caused by termites or mold consumes a lot of money and time. Select and use wood preservatives to prevent biological damage: Wood preservatives were selected and the worst environmental conditions, temperature 60±3℃, humidity 55±5%, and light intensity of 0.35 W/m2, were subjected to aging treatment to analyze chemical changes. Through the deterioration process, it was confirmed that the change in color difference decreased in the wood preservative treatment compared to the Control group. As a result of measuring the content of the active ingredient contained in the deterioration process of the wood preservative, it was confirmed that the active ingredient content of Gori22 and Bondex Preserve III was higher than that of the comparative Wood Keeper A. Through experiments, the shelf life and treatment period can be predicted by measuring the extent to which wood preservatives affect the change of wood specimens during the deterioration process and the content of active ingredients. In conclusion, various wood preservatives were prepared, and the possibility of selectively selecting wood preservatives according to the environment, topography and period was presented as a major evaluation factor.

  • Lymph nodes (LNs) are crucial sites where immune responses are initiated to combat invading pathogens in the body. LNs are organized into distinctive compartments by stromal cells. Stromal cell subsets constitute special niches supporting the trafficking, activation, differentiation, and crosstalk of immune cells in LNs. Fibroblastic reticular cells (FRC) are a type of stromal cell that form the three-dimensional structure networks of the T cell-rich zones in LNs, providing guidance paths for immigrating T lymphocytes. FRCs imprint immune responses by supporting LN architecture, recruiting immune cells, coordinating immune cell crosstalk, and presenting antigens. During inflammation, FRCs exert both spatial and molecular regulation on immune cells through their topological and secretory responses, thereby steering immune responses. Here, we propose a model in which FRCs regulate immune responses through a three-part scheme: setting up, supporting, or suppressing immune responses. FRCs engage in bidirectional interactions that enhance T cell biological efficiency. In addition, FRCs have profound effects on the innate immune response through phagocytosis. Thus, FRCs in LNs act as gatekeepers of immune responses. Overall, this study aims to highlight the emerging roles of FRCs in controlling both innate and adaptive immunity. This collaborative feedback loop mediated by FRCs may help maintain tissue function during inflammatory responses.

  • The filamentous fungus Fusarium graminearum is an important cereal pathogen. Although quantitative realtime PCR (qRT-PCR) is commonly used to analyze the expression of important fungal genes, no detailed validation of reference genes for the normalization of qRT-PCR data has been performed in this fungus. Here, we evaluated 15 candidate genes as references, including those previously described as housekeeping genes and those selected from the whole transcriptome sequencing data. By a combination of three statistical algorithms (BestKeeper, geNorm, and NormFinder), the variation in the expression of these genes was assessed under different culture conditions that favored mycelial growth, sexual development, and trichothecene mycotoxin production. When favoring mycelial growth, GzFLO and GzUBH expression were most stable in complete medium. Both EF1A and GzRPS16 expression were relatively stable under all conditions on carrot agar, including mycelial growth and the subsequent perithecial induction stage. These two genes were also most stable during trichothecene production. For the combined data set, GzUBH and EF1A were selected as the most stable. Thus, these genes are suitable reference genes for accurate normalization of qRT-PCR data for gene expression analyses of F. graminearum and other related fungi.

  • In this paper, a cyber space for multimedia conference is designed and implemented using gatekeeper and web service which satisfies H.323 standards. The implemented gatekeeper manages a registration and a call control for H.323 video conference terminals. The implemented gate-keeper can manage registered users efficiently with directory services using web service. Also, software maintenance of video conference system is established by service provider instead of users using control download on web. finally, we present the practical use of video conference through various applications of directory services.

  • Storytelling, a medium that arouses the customers' purchasing need by playing on their emotions, is the best content that can be used as it can increase the value of goods using information. This paper's significance is that it suggests cultural products that can be used by using Baeke relic Jinmyosu (Guard Animals) as a motif. The purpose was to present the possibility of high value-added cultural products using storytelling techniques. This study developed storytelling by adding the meaning of Jinmyo and Beoksa, who calm protected their masters from evil forces with horns and wings, and has the meaning of ascending into heaven and guiding the soul on the right path. That image gives a glimpse of originality and differentiation to Baekje. This study proposed 4 cultural products as 'Keeper Stone Mason' and 4 'Stone Mason Teller.' The proposed cultural products can help to give correct awareness of Baekje culture through a correct understanding of the historical significance of the Baeke relic, Jinmyosu. Moreover, it will help promote the originality and excellence of Baekje culture around the world by enhancing the value of Baekje culture. This study is expected to be used as a guideline for further research on developing cultural products that can create added value in various fields.

  • Objective: The aims of this study is to investigate the internal and external environment surrounding fathers and to promote play-participation with children and father-Infants Intimacy by identifying the influence of a father's belief concerning gender-equal parental role and the mother's roles as a gatekeeper. Methods: The participants of this study were 291 fathers who had infants ranging from 1-36 months of age and were living in Seoul and South Chungcheong Province. The data were collected through the questionnaires and analyzed using the SPSS 24.0. Results: The main results are as follows. First, gender roles, livelihood keeper-father beliefs, importance of father rearing, and the mother's role as a doorkeeper affect the father's participation in play. This differs according to the characteristics of each type of play. Second, it was found that the father's gender roles and the mother's role as a doorkeeper had a significant effect on the intimacy between the father and the infant. Conclusion/Implications: The results of this study revealed that fathers' belief in gender-equal parenting and mothers' encouragement through opening the door as gatekeepers affect the formation of intimacy between fathers and their children in infancy, and are factors that influence play participation.

  • The purpose of this study is to prove the global OTT, Netflix's organizational resilience (OR). For this, we review previous literatures regarding Netflix's OR and the theoretical logic of the OR. Then, we investigate Netflix's organizational culture (OC), corporate structure and business strategies based on the five levers of the OR. As a result, the first lever, the coordination makes Netflix to get rid of the inner wall by creating Netflix terms like 'sunshining,' and 'postmortem,' which makes their employees extraordinarily candid with each other. The second lever, the cooperation provides employees with understanding customers by sharing company and service information openly and broadly through transparent board system, billboard advertising, etc. The third lever, the clout allows Netflix to encourage independent decision-making by their employees. Netflix customers are under scrutiny and served 24/7 via live chat or phone by supporting a high-performance workplace. The fourth lever, the capabilities are related to Netflix's keeping highly effective people and it establishes a culture of highly motivated employees. The "dream team" policy is run by what is known as the "keeper test." The last lever, the connections make Netflix to forge external strategic partnership to stay agile. There is no rule for partnering with key content producers by allowing creative freedom to them.
