Youngwoo Nam(남영우),Insoo Son(손인수),Dongwon Lee(이동원) 한국지능정보시스템학회 2011 지능정보연구 Vol.17 No.4

In this paper, we explore the information diffusion mechanism under social network environments by investigating the effect of message characteristics on the volume and speed of retweeting in Twitter, a popular online social media service. To this end, we select eight main keywords (i.e., ‘무상급식’, ‘반값등록금’, ‘나가수’, ‘평창’, ‘김연아’, ‘박태환’, ‘아이폰’, ‘갤럭시’) that have been popular on online social media in recent days. Each keyword represents various social aspects of Korea that recently grab people’s attention such as political issues, entertainment, sports celebrities, and the latest digital products, and eventually holds distinctive message characteristics. Analyzing the frequency and velocity of retweeting for each keyword, we find that more than half of the sample messages posted on Twitter contain personal opinions for the certain keyword, but we also find that the tweets which include objective messages with hyperlink are the fastest ones when being retweeted by other followers. In overall, when being retweeted, the group of messages related to the certain keyword present distinctive diffusion patterns and speed according to message characteristics. From academic perspective, the findings in the study broaden our theoretical knowledge of information diffusion mechanism over online social media. For practitioners, the results also provide managerial implications regarding how to strategically utilize online social media for marketing communications with customers.

Hepatitis E Virus Methyltransferase Inhibits Type I Interferon Induction by Targeting RIG-I

( Sangmin Kang ),( Changsun Choi ),( Insoo Choi ),( Kwi-nam Han ),( Seong Woon Roh ),( Jongsun Choi ),( Joseph Kwon ),( Mi-kyung Park ),( Seong-jun Kim ),( Jinjong Myoung ) 한국미생물생명공학회(구 한국산업미생물학회) 2018 Journal of microbiology and biotechnology Vol.28 No.9

The type I interferons (IFNs) play a vital role in activation of innate immunity in response to viral infection. Accordingly, viruses have evolved to employ various survival strategies to evade innate immune responses induced by type I IFNs. For example, hepatitis E virus (HEV) encoded papain-like cysteine protease (PCP) has been shown to inhibit IFN activation signaling by suppressing K63-linked de-ubiquitination of retinoic acid-inducible gene I (RIG-I) and TANK-binding kinase 1 (TBK1), thus effectively inhibiting down-stream activation of IFN signaling. In the present study, we demonstrated that HEV inhibits polyinosinic-polycytidylic acid (poly(I:C))-induced IFN-β transcriptional induction. Moreover, by using reporter assay with individual HEV-encoded gene, we showed that HEV methyltransferase (MeT), a nonstructural protein, significantly decreases RIG-I-induced IFN-β induction and NF-κB signaling activities in a dose-dependent manner. Taken together, we report here that MeT, along with PCP, is responsible for the inhibition of RIG-I-induced activation of type I IFNs, expanding the list of HEV-encoded antagonists of the host innate immunity.

Yoon, Young-Gon,Choi, Insoo,Lee, Chang-Ha,Han, Jonghee,Kim, Hyoung-Juhn,Cho, EunAe,Yoo, Sung Jong,Nam, Suk Woo,Lim, Tae-Hoon,Yoon, Jong Jin,Park, Sehkyu,Jang, Jong Hyun Korean Chemical Society 2014 Bulletin of the Korean Chemical Society Vol.35 No.12

This paper describes how primary contaminants in ambient air affect the performance of the cathode in fuel cell electric vehicle applications. The effect of four atmospheric pollutants ($SO_2$, $NH_3$, $NO_2$, and CO) on cathode performance was investigated by air impurity injection and recovery test under load. Electrochemical analysis via polarization and electrochemical impedance spectroscopy was performed for various concentrations of contaminants during the impurity test in order to determine the origins of performance decay. The variation in cell voltage derived empirically in this study and data reported in the literature were normalized and juxtaposed to elucidate the relationship between impurity concentration and performance. Mechanisms of cathode degradation by air impurities were discussed in light of the findings.
