This study was designed to examine the in vitro antioxidant, antimicrobial and anti-inflammation effects of essential oils of Erigeron annuus L. Flower. Erigeron annuus L. essential oils were obtained by solvent extraction. Antioxidative ability was evaluated by bioassays using ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid diammonium salt) radical scavenging effect and 2, 2-diphenyl-1-1-picrydrazyl (DPPH) free radical scavenging activity. Erigeron annuus L. essential oil exhibited free radical scavenging activity on ABTS and DPPH 98.6%, 48.3% respectively, at a concentration of $500{\mu}g/ml$. Antimicrobial activity of essential oils of Erigeron annuus L. were tested against Staphylococcus aureus (S. aureus), Propionibacterium acnes (P. acne) and Escherichia coli (E. coli) by paper disc method, MIC and MBC. Erigeron annuus L. essential oil showed excellent antibacterial activities against S. aureus with MIC and MBC values of 0.31 mg/mL. The clear zone, indicating antimicrobial activity against P. acnes, was 14 mm, MIC and MBC values 0.31 mg/mL, 0.63 mg/mL, respectively. For the anti-inflammatory activity in RAW 264.7 cell, the Erigeron annuus L. essential oils inhibited not only NO production but also the expression of pro-inflammatory cytokines such as, TNF-${\alpha}$, IL-6 in a dose-dependent manner. These results suggested that Erigeron annuus L. essential oils has considerable potential as a cosmetic ingredient with antioxidative, antimicrobial and anti-inflammation effects.

The election broadcast began utilizing virtual studios in the mid-1990s. In 1996, SBS's virtual studio was evaluated as an innovation in Korean broadcasting technology that introduced the world's first virtual studio. However, there have been cases where KBS and MBC named it a virtual studio and used it for election broadcasting. Various CG (Computer Graphics) case studies of election broadcasting have been conducted since the 2000s, but the initial research is inadequate. Therefore, this paper complements existing research by analyzing the cases of the mid-1990s when they actually started using virtual studios. Beginning with SMOCKEY (KBS) and MAGICII (MBC) in 1995, we presented the initial model of the virtual studio, and then with SBS Virtual Studio, each broadcasting company evolved into the names Dream Studio (KBS) and Space 21 Studio (MBC). As a result of the analysis, it was found that the election broadcast is a chart showing the data and the winning prediction, and that the election broadcast was the trigger to compose the story based on the introduction of the virtual studio. It is a form of historical research dealing with the value of the early virtual studios in this paper. It is meaningful to see the process of Remediation.

This study examined the social capital and geographical gaps of local television stations using web data gathered through website crawling. URLs for 16 local MBC websites were collected. MBC is an abbreviation for Munhwa Broadcasting Corporation, one of South Korea's largest television and radio broadcasters. Munhwa is a Sino-Korean term that means "culture." It initially determined which institutions local broadcasting stations were linked to using a Web Impact Report. To investigate the specific connection type, URL information was classified using the n-tuple helix model, followed by 2-mode network analysis. The n-tuple helix model is an analysis method that extends the standard university-business-government triple-helix model by including a new network innovation originator. As a result, local broadcasting stations relied heavily on activities like as festivals, performances, and exhibitions to engage the local community. Local stations in Daegu-Gyeongbuk area and the Busan-Ulsan-Gyeongnam area were identified as having the most diverse connections to the local population among other regions.

The effects of borax on the phase formation of C2S, C4A3 and $\alpha$'-C2S phases. It has negative effects on formation of C4A3 And it lowers the forming temperature of C4AF. It also has been found that borax improves the clinkerization of MBC. In the MBC clinker with borax 3% C2S have larger and more irregular shapes, larger C/S mole ratio and C4A3 have smaller size larger C/ molr ratio than in the clinker without borax.
