As part of the digital era, a digital twin that simulates the weak part of a product by performing a stress test that reduces the lifespan of some expensive equipment that cannot be done in reality by accurately moving the real world to virtual reality is being actively used in the manufacturing industry. Due to the development of IoT, the digital twin, which accurately collects data collected from the real world and makes it the same in the virtual space, is mutually beneficial through accurate prediction of urban life problems such as traffic, disaster, housing, quarantine, energy, environment, and aging. Based on its action, it is positioned as a necessary tool for smart city construction. Although digital twin is widely applied to the manufacturing field, this study proposes a smart city model suitable for the 4th industrial revolution era by using it to smart cities and increasing citizens' safety, welfare, and convenience through the proposed model. In addition, when a digital twin is applied to a smart city, it is expected that more accurate prediction and analysis will be possible by real-time synchronization between the real and virtual by maintaining realism and immediacy through real-time interaction.

The leaves of Selaginella tamariscina were used for the treatment of many diseases in traditional medicine. In the study, antioxidant, anti-inflammatory, and wound healing activities of the hot-water extract(STW) and 80%ethanol extract(STE) obtained from S. tamariscina were evaluated. As a result, the polyphenol content of STW and STE were 38.108±0.766 mg/g and 17.927±1.064 mg/g, respectively. The DPPH and ABTS radical scavenging activities with the IC50 values of the STW were over 2 times lower than that of the STE. In the MTT assay, RAW264.7 cell viability of two extracts was decreased by about 6% at 1 mg/mL, whereas for HaCaT cell viability increased by 18% at 50 ㎍/mL. In addition, STW and STE suppressed the production of nitric oxide(NO), Tumor-necrosis(TNF)-��. COX-2 and PGE2 in lipopolysaccharide(LPS) induced RAW264.7 cells. Furthermore, the STE showed wound healing effect through the promotion of skin cell migration in TNF-�� stimulated human keratinocytes. These results indicated that the STW and STE have the potential to be used as a new cosmetic active ingredients in skin care.
