This paper presents a social network analysis of changes in Home Economics education content loaded on YouTube before and after the outbreak of COVID-19. From January 1, 2008 to June 30, 2021, a basic analysis was conducted of 761 Home Economics education videos loaded on YouTube, using NetMiner 4.3 to analyze important keywords and the centrality of video titles and full texts. Before COVID-19, there were 164 Home Economics education videos posted on YouTube, increasing significantly to 597 following the emergence of the pandemic. In both periods, there was more middle school content than high school content. The content in the child-family field was the most, and the main keywords were youth and family. Before COVID-19, a performance evaluation indicated that the proportion of student content was high, whereas after the outbreak of the disease, teacher content increased significantly due to the effect of distance learning. However, compared with video use, the self-expression and participation of users were lower in both periods. The centrality analysis indicated that in the title, 'family' exhibited a high degree of both centrality and eigenvector centrality over the entire period. Degree centrality of the video title was found to be high in the order of class, online, family, management, etc. after the outbreak of COVID-19, and the connection of keywords was strong overall. Eigenvector centrality indicated that career, search, life, and design were influential keywords before COVID-19, while class, youth, online, and development were influential keywords after COVID-19.

In 2019, Disney's musical film "Aladdin" was newly introduced with Princess Jasmine's theme song "Speechless," which was not featured in the animation "Aladdin" in 1992. Written as a theme song, "Speechless" expresses Princess Jasmine as a self-reliant, enterprising and dignified woman. The song made the change in Princess Jasmine's character very articulate. She has developed herself as an active and enthusiastic character from a rather passive and reserved figure. The musical film "Aladdin" has drawn much attention and love from many audiences with its own narrative and original songs, but the addition of a new theme song "Speechless", which was not in the animation in 1992, made the musical film "Aladdin" even more powerful and meaningful. The study examined the organic relationship between the musical features and narratives of the newly included theme song 'Speechless' in the musical film Aladdin. Through the analysis of the six scenes that include the musical features of the theme song "Speechless," the study looked at how the relationship between music and narratives had an influence on cinematic expression.

Quercetin, a flavonoid found in fruits and vegetables, exhibits a strong anti-inflammatory activity. The objective of this study was to examine the effect of quercetin on chemotactic activity of peripheral blood polymorphonuclear cells (PMNs) to culture supernatant from peripheral blood mononuclear cells (PBMCs) stimulated with lipopolysaccharide (LPS). In addition, we determined whether this effect is related to interleukin (IL)-8 and changes in cytoskeleton. The chemotactic activity of PMNs was evaluated by a modified Boyden chamber assay. Total cellular filamentous (F)-actin levels were measured by method of fluorescence microscopy. The levels of IL-8 mRNA and protein were measured by real time polymerase reaction method and enzyme-linked immunosorbent assay, respectively. Quercetin (0-50 µM) itself has no chemoattractant effect for PMNs. The culture supernatant from PBMCs (2 × 10⁶ cells/mL) treated with LPS (1 ㎍/mL) showed remarkable increase in chemotaxis of PMNs. However, this effect was reduced dose-dependently by treatment with quercetin. In addition, PBMCs treated with LPS revealed enhanced levels in IL-8 protein and mRNA. Co-treatment of LPS with quercetin (50 µM) in PBMCs decreased IL-8 production and expression. Treatment of quercetin (0-50 µM) on PMNs to rpIL-8 (10 nM) decreased dose-dependently the chemotactic activity of PMNs. Treatment of quercetin on PMNs to IL-8 also reduced their total cellular F-actin level. These results suggested that quercetin attenuates chemotactic activity of PMNs, which is mediated by down-regulation of IL-8 production from LPS-stimulated PBMCs and inhibition of F-actin polymerization in PMNs.

UV radiation is the most dangerous stress factor among permanent environmental impacts on human skin. Consequences of UV exposure are aberrant tissue architecture, alterations in skin cells including functional changes. Nowadays new kinds of outdoor leisure-time activities and changing environmental conditions make the question of sun protection more important than ever. It is necessary to recognize that self-confident consumers do not consider to change their way of life, they demand modern solutions on the basis of new scientific developments. In the past one fundamental principle of cosmetics was the use of physical and organic filter systems against damaging UV-rays. Today new research results demonstrate that natural protecting cell mechanisms can be activated. Suitable biological actives strongly support the protection function not from the surface but from the inside of the cell. A soy seed preparation (SSP) was proven to stimulate natural skin protective functions. The major functions are an increased energy level and the prevention of DNA damage. These functions can I be defined as biological UV protection. The tumor suppressor protein p53 plays a key role in the regulation of DNA repair. p53 must be transferred into the phosphorylated form to work as transcription factor for genes which are regulating the cell cycle or organizing DNA repair. A pretreatment with SSP increases the phosphorylation rate of p53 of chronically UV-irradiated human keratinocytes significantly. According to the same test procedure SSP induces a dramatic increase in the expression of the tumor suppressor protein p14$^{ARF}$ that is supporting the p53 activity by blocking the antagonist of p53, the oncoprotein Mdm2. Mdm2, a ubiquitin E3-ligase, downregulates p53 and at the same time it prevents phosphorylation of p53. The positive influence of the tumor suppressor proteins explains the stimulation of DNA repair and prevention of sunburn cell formation by SSP, which was proven in cell culture experiments. In vivo the increased skin tolerance against UV irradiation by SSP could be confirmed too. We have assumed, that an increased repair potential provides full cell functionality.y.

This study attempted to understand current status of overseas virtual fashion brands and analyze attributes of common digital fashion brands. Based on brand analysis criteria of previous studies, digital fashion brands were analyzed for brand concept, price range, characteristic elements, and attributes. Digital fashion design elements of items, colors, materials, patterns, and effects were analyzed by collecting images of brands' digital fashion design products. Digital fashion brands could be divided into experimental and creative digital fashion brands and digital fashion brands aiming for popular brands. This study introduces a creative fashion collection that experiments sustainability and future value. It shares a new way of self-expression and a playful culture centered on the younger generation. In terms of fashion design elements, fashion items were similar to the existing fashion category, but included other accessories that reflected the lifestyle of Generation Z. Silhouette expressed a minimalistic futuristic image centered on straight silhouettes. Color showed a bold and modern color image through black and color contrast. Unique patterns reflecting the concept of the brand appeared, centering on abstract and geometric patterns. Regarding materials and effects, new elements differentiated from existing fashion design area, showing meaningful characteristics. Digital materials are developed and proposed for sustainability. Materials (such as metal, glass, plastic) and effects (such as weightlessness, flames) expand impossible senses in reality and enable new fashion experiences. This is a case study of digital fashion brands. It is meaningful in that it identifies characteristics and discusses their values and meanings.

This study focuses on online communities and the ritual conversations of users when participating in sharing activities. The study aims to understand the social and psychological phenomena that occur between users within the context of Erving Goffman's impression management theory. Case studies and a content analysis were conducted by collecting posts and comments related to fashion products in the sharing activities category on Naver Cafe "Family Sale." On the one hand, the study identified various disposition motives among givers, including a desire for recognition, self-expression, activation of the community, emotional sympathy, goodwill, play, and simple disposition. On the other hand, receivers' purchase motives included the need for a product, reciprocation based on a sense of belonging, play, gift-giving, and simple response. Analyzing the posts of givers and the comments of receivers of fashion products using impression management strategies and dramaturgical analysis, the study interpreted users' impression management and revealed propensities in fashion consumption: fashionability, conspicuousness, value orientation, and economic feasibility. Through ritual conversations, users managed to attain emotional stability on an individual level, while they reinforced collective bonds on a social level. They fulfilled their roles with their own narratives to achieve personal and collective goals in a non-face-to-face situations and non-monetary transactions. This study is significant in that it examines normative communication in an online community and user relationships to understand a recent phenomenon in the fashion industry.

Objectives: Current social norms in the United States do not favor breastfeeding in public. This study examined associations between college students' explicit and implicit emotions of breastfeeding in public and their intention to support public breastfeeding. Methods: Twenty-two student participants viewed images of a breastfeeding woman with a fully-covered, fully-exposed, or partially-exposed breast in a public setting. After viewing each image, participants' explicit emotions (self-reported) of the image were measured using a questionnaire and their implicit emotions (facial expression) were measured using FaceReader technology. We examined if a relationship exists between both emotions [toward images] and intention to support breastfeeding in public using correlation techniques. We determined the relative influence of two emotions on the intention to support breastfeeding in public using regression analyses. Results: The nursing images depicting a fully-covered breast (r = 0.425, P = 0.049 vs. r = 0.271, P = 0.222) and fully-exposed breast (r = 0.437, P = 0.042 vs. r = 0.317, P = 0.150) had stronger associations with explicit emotions and intention to support breastfeeding in public compared to implicit emotions and intention. Breastfeeding knowledge was associated with a positive explicit emotion for images with partial- (β = 0.60, P = 0.003) and full-breast exposure (β = 0.65, P = 0.002). Conclusions: Explicit emotions appear to drive stated intentions to support public breastfeeding. Further research is needed to understand the disconnect between explicit and implicit emotions, the factors that influence these emotions, and whether stated intentions lead to consistent behavior.

The purpose of this study is to examine the implications of Deleuze and Guattari's Machinism and Pedagogy of Assemblages. A slow, empirical process offered by Deleuze and Guattari is possible only if they experience a repetition of the duration in time. The identity of this world, a combination of potential and reality, is expressed as a machine. The identity of the 'machine' is the generation. The identity of the information society that exists everywhere in the cloud and unconsciously collects big data is also the information society. The information society is at risk of leaning toward a society in which individual desires are managed prior to the manifestation of a self-reliance a machine consisting of unmarked and mechanical arrangements. Social science based on the theory of layout shares the characteristics of repetition patterns, coexistence of linguistic and materiality, attention to boundary and negation to total whole. The pedagogy of layout, in which the collective pattern is structurally deformed in time, conforms to the original problem consciousness of Deleuze and Guattari, slow and empirical education. In addition, the work of examining the materiality and expression of the education-machine will contribute to the establishment of a new learning theory, an educational theory in the era of trans-human.

Spatial cable systems can provide more transverse stiffness and torsional stiffness without sacrificing the vertical bearing capacity compared with conventional vertical cable systems, which is quite lucrative for long-span earth-anchored suspension bridges' development. Higher economy highlights the importance of refined form-finding analysis. Meanwhile, the internal connection between the lateral and vertical sags has not yet been specified. Given this, an analytic algorithm of form-finding for the earth-anchored suspension bridge with spatial cables is proposed in this paper. Through the geometric compatibility condition and mechanical equilibrium condition, the expressions for cable segment, the recurrence relationship between catenary parameters and control equations of spatial cable are established. Additionally, the nonlinear general reduced gradient method is introduced into fast and high-precision numerical analysis. Furthermore, the analytic expression of the lateral and vertical sags is deduced and discussed. This is very significant for the space design above the bridge deck and the optimization of the sag-to-span ratio in the preliminary design stage of the bridge. Finally, the proposed method is verified with the aid of two examples, one being an operational self-anchored suspension bridge (with spatial cables and a 260 m main span), and the other being an earth-anchored suspension bridge under design (with spatial cables and a 500 m main span). The necessity of an iterative calculation for hanger tensions on earth-anchored suspension bridges is confirmed. It is further concluded that the main cable and their connected hangers are in very close inclined planes.

The epistolary novel, as developed and refined by Samuel Richardson (1689-1761), is concerned with distinctly private experience and the morality of individuals-Richardson's heroine writers. In contrast to nineteenth-century novels, which explore their subjects through the overview of a narrator with a singular moral outlook, the epistolary narrative allows Richardson to examine the various different ways in which individuals/heroines interpret, mold, and respond to their experiences in writing. In this paper, I argue that the authorial voice of Richardson does not control the narrative but rather is present in the prefaces, character sketches, notes and occasional interjections between letters. Although there is little doubt as to whether Richardson intended to make a particular moral point or attempted to control the effect of his novels on his readers, the heroines and their letters dominate the novels so that they put the authorial suggestions in a different light, reducing the author's to one voice among several. Thus, Pamela's letters are exemplary for the vigor and intelligence with which they appear to be written, rather than for the imposed morality of their ghost writer-Richardson. Although Clarissa is of a different social class from Pamela, both heroines are united in their oppression as victims of a patriarchal society. In Clarissa's letters, the heroine's situation and experience are seen through her own writing in dialogue with that of her confidante Anna Howe, and in contrast to the writing of her oppressors. Clarissa, then, becomes a struggle between different discourses in which their genesis and effect, and the societies and individuals from which they come are implicitly suggested in Richardson's text. While Richardson may or may not be guilty of taking the writing of women and using it for his own ends, his epistolary novels represent a deliberate and bold attempt to shape the novel in a way conducive to his heroines and to women writers.
