기존의 재난 안전 문자는 기지국으로부터 일정 거리에 있는 기기에 안전 문자를 전송하는 것으로, 문자를 수신받은 사용자가 위치한 지역과 다른 지역의 방역정책을 수신받는 경우가 있어 지자체별로 방역정책이 상이한 현 상황에서 상당히 불편하게 작용하였다. 본 논문에서는 QR 코드 인식을 통한 위치 기반의 코로나 19 방역제도 알림 시스템을 구현하였으며 보다 즉각적이고 정확한 방역 알림을 받아 지자체 경계지역에서 상이한 방역제도로 인한 시민들의 혼란을 줄일 것으로 기대된다. Existing disaster safety texts are sending safety texts to devices within a certain distance from the base station, and quarantine policies in different regions are sometimes received, making it quite inconvenient for each local government to have different quarantine policies. In this thesis, a location-based COVID-19 quarantine system notification system was implemented through QR code recognition, and it is expected to reduce confusion among citizens due to different quarantine systems in the border area of local governments by receiving more immediate and accurate quarantine notifications.

Green facade has a significant impact on building’s energy performance by controlling the absorption of solar radiation and improving outdoor thermal comfort through shading and evapotranspiration. In particular, since high-density building does not enough green space, green facade, and rooftop greening using artificial ground plants are highly utilized. However, the level of cooling effect according to plant traits and irrigation control is different. Therefore, in this study, the cooling effect analyzed for a total of 4 cases by controlling the irrigation condition based on hedera and spurge. Although hedera under sufficient water had the highest cooling effect(-2℃~-4℃), had the lowest cooling effect under non-irrigation(+1.1℃~+4.4℃). In addition, hedera under sufficient water had cooling effect than hedera under non-irrigation(-1℃~-8.1℃) and in the case of spurge, it had cooling effect(-0.3℃~-7.8℃) more than non-irrigation. As a result of measuring the amount of transpiration according to the light intensity (PAR) and carbon dioxide concentration conditions, transpiration of hedera was higher than the spurge (respectively 0.63204mmolm<sup>-2</sup>s<sup>-1</sup>, 0.674367mmolm<sup>-2</sup>s<sup>-1</sup>). The difference in the cooling effect of the green facade under irrigation condition was significant. But the potential cooling effect of green facade according to plants species was different. Therefore, in order to maximize and continuously provide the cooling effect of green facade in urban areas, it is necessary to consider the characteristics of plants and the control of water supply through the irrigation system.
