Nous trouvons frequemment des tendances analytiques qui datent l'origine de la bande dessinee l'ege prehistorique. Ce point de vue risque de susciter des malentendus en ce qui concerne le medium dans son etat actuel. S'il y a un lien entre deux peles lointains, il est tres faible meme si nous ne pouvons confirmer ces origines qui n'ont rien e voir avec la bande dessinee d'aujourd'hui. Nous consid.rons de Richard Felton Outcault en 1896 comme l'origine de la bande dessinee actuelle que nous proposons d'appeler la "bande dessinee moderne" en s'ecartant de ses formes precedentes. Nous tentons de la definir sous la perspective historique dans cet article. Cette approche nous permet bien de comprendre une nouvelle forme de la bande dessinee sur un support neuf, l'ecran d'ordinateur.

In this work, a ruthenium dioxide electrode has been prepared by thermal decomposition at 400 ℃ then used for the oxidation of commercial amoxicillin. The physical characterization showed that RuO₂ electrode presents a mud cracked structure. Its electrochemical characterization has revealed an increase of the voltammetric charge in acid electrolyte compared to neutral electrolyte indicating the importance of protons in its surface redox processes. The voltammetric study of the oxidation of amoxicillin has been investigated. It has been obtained that the oxidation of amoxicillin is controlled by both adsorption and diffusion processes. Moreover, the oxidation of amoxicillin occurs via direct and indirect processes in free or electrolyte containing chlorides. Through preparative electrolysis, enhancement of amoxicillin oxidation was observed in the presence of chloride where the amoxicillin degradation yield reached more than 50 % compared to less than 5% in the absence of chlorides. Spectrophotometric investigations have revealed the degradation of intermediates absorbing at 350 nm.

This research analyzed the characteristics of Hanfu street snaps in the Chinese version of TikTok to determine the development and meaning of Hanfu. Based on grounded theory, this study selected 102 representative cases by sorting Hanfu street snaps on TikTok according to popularity. Subsequently, through open coding, the cases were organized and summarized into five main categories. The findings are as follows: 1) The national cultural pride has enabled a greater number of Hanfu fans and groups to upload short videos promoting the Hanfu movement on TikTok to expand the influence of the activities and popularize cultural knowledge. 2) The users attempted cross-cultural communication by participating in cultural festivals in Western countries wearing Hanfu. 3) The 'See now buy now' function of TikTok enables numerous Hanfu merchants to upload short videos about Hanfu products to promote their products and boost sales. 4) As 'gamification' affects everyday life, computer game enthusiasts among them wear Hanfu in the form of role-playing. 5)As a unique "meme" phenomenon on TikTok, wearing Hanfu to make interesting videos has also become a form of entertainment. Thus, although the characteristics of Hanfu street snaps on TikTok originated from the transmission of Hanfu culture, the culture has now been transformed through social media into symbolic consumption and play culture.

Mammalian urothelium undergoes unique membrane specialization by making the asymmetric unit membrane (AUM) that is covered with the apical cell surface during terminal differentiation. The AUM contains several major integral membrane proteins including uroplakin Ia, Ib, II and III. The genes for uroplakins have been cloned from humans and mice, but not from porcine. In this study, we report the cloning of the UPII genomic DNA, which codes for the full length open reading frame for the uroplakin II protein. The deduced amino acid sequence encodes of a hydrophobic NH$_2$-terminal peptide, a prosequence, and a mature protein. The prosequence contains three potential N-glycosylation sites and a RGRR cleavage site that may be involved in uroplakin II processing and maturation. Northern and immunohistochemistry analyses showed that the porcine UPII gene is only expressed in urothelium and that the protein was specifically localized in urothelial superficial cells. A 2kb of upstream in the promoter sequence contains multiple transcription factor binding sites, including GC-box, SPI, AP2, and GATA-box sites, but not for TATA or CAAT-box sequences. Comparison of the porcine UPII promoter sequence with that of the murine by MEME system presented two conserved motifs, suggesting a cis-acting regulatory role for the conserved sequences. Sequence homology between two species in motif A and B was 79% and 80% respectively, although their relative locations were different. During the gestation, mouse bladder at estrus stages and day 10 after parturition showed higher UPII expression, while showed lower expression at peri-implantation stage. Taken together, our results showed that the porcine UPII gene was expressed highly and specifically in the bladder urothelium and that steroid hormones for implantation changed the expression of UPII in the bladder, although the biological significance of UPII remains to be not determined.

Silicon (Si) has the potential to improve plant growth and stress tolerance. The study aimed to explore Si-involving plant responses and molecular characterization of different Si-responsive genes in alfalfa. In this study, the exogenous supplementation of Si enhanced plant growth, and biomass yield. Si-acquisition in alfalfa root and shoot was higher in Si-supplemented compared to silicon deficient (-Si) plants, implying Si-acquisition has beneficial on alfalfa plants. As a consequence, the quantum efficiency of photosystem II (Fv/Fm) was significantly increased in silicon-sufficient (+Si) plants. The quantitative gene expression analysis exhibited a significant upregulation of the Lsi1, Lsi2, Lsi3, NIP5;1, and NIP6;1 genes in alfalfa roots, while BOR1, BOR4, NIP2, and NIP3 showed no significant variation in their expression. The MEME results further noticed the association of four motifs related to the major intrinsic protein (MIP). The interaction analysis revealed that NIP5;1 and Lsi1 showed a shared gene network with NIP2, BOR1, and BOR4, and Lsi2, Lsi3 and NIP3-1, respectively. These results suggest that members of the major intrinsic proteins (MIPs) family especially Lsi1, Lsi2, Lsi3, NIP5;1, and NIP6;1 genes helped to pass water and other neutral solutes through the cell membrane and those played significant roles in Si uptake and transport in plants. Together, these insights might be useful for alfalfa breeding and genome editing approaches for alfalfa improvement.

Webtoon is the most popular cultural contents representing contemporary Korea. This study explores the cultural aspects of participatory culture surrounding Webtoon, and reveals the cultural implications of webtoon in contemporary Korea. Particularly, this study notes that the engagement of the participatory culture is formed from the user-generated images and analyzes the reproduction patterns of them. Chapter 2 analyzes the mimicking process of user-generated images based on the 'meme' concept. Especially based on the variation degree of text or image, the user-generated images could be classified into three types of 'completely variant', 'partly variant', and 'completely same'. Users use these images as one of the fun factor by transplanting them into daily messenger conversation. Chapter 3 reveals the cultural meaning which is derived from the process of user-generated images creation. In particular, this study notes that most of the user-generated images are mimicking the main character of the original webtoon, and analyzes the underlying desire of the mass based on the literary theory of Northrop Frye. The main readers of webtoon are petit-bourgeois living in Korean metropolitan, and the user-generated images also reflects the daily lives of these ordinary people. User-generated images of webtoon are imitating the original contents in a way of replicating or mutating the images or texts. Also, they are consumed and enjoyed as an amusing code among users. Especially by mimicking the appearance of the main character in a self-reflective way, they appeal to day-to-day sympathy of users. In that user-generated images reveal the desire of the public living in contemporary Korea, this study examines the cultural implication of webtoon.

In this study, we investigated the antibacterial, antioxidant, and whitening effects of Prunus persica Batsch var. davidiana Max. (Feral Peach) and Prunus mume (white and pink) flowers. The extracts of the three kinds of flowers showed antibacterial activity against Staphylococcus. aureus. The chloroform fractions of the white Prunus mume, Feral Peach, and pink Prunus mume flowers exhibited antibacterial activities of 84, 49, and 30%, respectively, against Staphylococcus. aureus at a concentration of 0.5 mg/mL. The flower extracts of the three species also exhibited antibacterial effects against Pseudomonas. aeruginosa. The chloroform fractions of the Feral Peach and pink Prunus meme flowers exhibited antibacterial activities of 36 and 30%, respectively, at a concentration of 0.5 mg/mL. These extracts did not exhibit any significant antibacterial activity against Staphylococcus. epidermidis and Escherichia. coli. The extracts of the three kinds of flowers did not significantly affect the survival of HaCaT cells. The distilled water fraction of the pink Prunus mume flower extract exhibited antioxidant effects at concentrations of both 20 and 40 ㎍/mL. The ethyl acetate fraction of the pink Prunus mume flower extract exhibited an antioxidant activity superior to glutathione at a concentration of 40 ㎍/mL. The flower extracts did not significantly affect the survival rate of B16F10 cells. The chloroform fraction of the Feral Peach flower exhibited a whitening effect of 18% at a concentration of 40 ㎍/mL. Based on these results, we conclude that the three kinds of flower extracts are raw materials exhibiting antibacterial, antioxidant, and whitening effects.

As seen in the recent K-pop craze, the size and influence of the Korean music industry is growing even bigger. At least 6,000 songs are released a year in the Korean music market, but not many can be said to have been successful. Many studies and attempts are being made to identify the factors that make the hit music. Commercial factors such as media exposure and promotion as well as the quality of music play an important role in the commercial success of music. Recently, there have been many marketing campaigns using Internet memes in the pop music industry, and Internet memes are activities or trends that spread in various forms, such as images and videos, as cultural units that spread among people. Depending on the Internet environment and the characteristics of digital communication, contents are expanded and reproduced in the form of various memes, which causes a greater response to consumers. Previously, the phenomenon of Internet memes has occurred naturally, but artists who are aware of the marketing effects have recently used it as an element of marketing. In this paper, the mediated effect of Internet memes in relation to the success factors of popular music was analyzed, and a prediction model reflecting them was proposed. As a result of the analysis, the factors with the mediated effect of 'cover effect' and 'challenge effect' were the same. Among the internal success factors, there were mediated effects in "Singer Recognition," the genres of "POP, Dance, Ballad, Trot and Electronica," and among the external success factors, mediated effects in "Planning Company Capacity," "The Number of Music Broadcasting Programs," and "The Number of News Articles." Predictive models reflecting cover effects and challenge effects showed F1-score at 0.6889 and 0.7692, respectively. This study is meaningful in that it has collected and analyzed actual chart data and presented commercial directions that can be used in practice, and found that there are many success factors of popular music and the mediating effects of Internet memes.
