신종 코로나바이러스(코로나 19)가 세계적으로 확산되면서, 각국은 코로나 19 에 대한 정보를 파악하기 위해 노력을 기울이는 중이며, 이에 대한 정보를 전달하고자 시각화 하려는 여러 시도를 하고 있다. 본 연구는 국내 방역 정책이 국내외로 긍정적인 평가를 받았다는 것을 시사점으로 국내 코로나 19 추세 현황과 방역정책의 관련성을 제시하는 시각화를 시도해보고자 한다. 효과적인 정보 전달을 위해 반응형 시각화(Interactive Visualization)를 채택하여 ’K-Colicy’ 시각화 모델을 구현하여 이에 대한 사용성 평가를 진행하였다.

This paper considers the wireless powered communication network (WPCN) that conveys power to the downlink and then transmits information to the uplink with a zero-forcing (ZF)-based spatial multiplexing scheme using the harvested power. We propose a low-complexity algorithm to optimize a multiuser multi-input multi-output (MU-MIMO) WPCN in terms of the max-min achievable rate. In the proposed algorithm, the uplink channel gain is approximated for simple power allocation, and the downlink beamforming vector is designed by considering the downlink and uplink-approximate channel gains. Through numerical simulations, it is verified that the proposed method provides good tradeoff between the complexity and performance.

<P><B>Abstract</B></P> <P>Acute lung injury (ALI) is an inflammatory lung disease caused by sepsis, infection, or ischemia-reperfusion. The receptor for advanced glycation end-products (RAGE) signaling pathway plays an important role in ALI. In this study, a novel RAGE-antagonist peptide (RAP) was produced as an inhibitor of the RAGE signaling pathway based on the RAGE-binding domain of high mobility group box-1 (HMGB1). Recombinant RAP was over-expressed and purified using nickel-affinity chromatography. In lipopolysaccharide- or HMGB1-activated RAW264.7 macrophage cells, RAP reduced the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). RAP decreased the levels of cell surface RAGE and inhibited the nuclear translocation of nuclear factor-κB (NF-κB). These results imply that RAP decreases RAGE-mediated NF-κB activation and subsequent inflammatory reaction. For in vivo evaluation, RAP was delivered to the lungs of ALI-model animals via intratracheal administration. As a result, RAGE was down-regulated in the lung tissues by pulmonary delivery of RAP. Consequently, TNF-α, IL-6, and IL-1β were also reduced in broncoalveolar lavage fluid and the lung tissues of RAP-treated animals. Hematoxylin and eosin staining indicated that inflammation was decreased in RAP-treated animals. Collectively, these results suggest that RAP may be a useful treatment for ALI.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
