Domestic broadcasting companies are obliged to provide the disaster information quickly to protect the public from the disaster, and people can prepare the disaster. Especially, Korea Broadcasting System (KBS) has a duty to deliver disaster news more quickly and accurately than other broadcasting companies because it is designated as a host broadcaster for disaster broadcasting services in accordance with Article 43 of the Broadcasting Act. This study examined how the KBS deals with social disaster news related to Zika virus, and evaluated whether they used the frames in a timely manner to help people prepare a disaster. Based on the results of this analysis, this study tried to suggest practical implications for measures to improve the efficiency and reliability of disaster news report.

본 연구에서는 2016년 전 세계에 공포를 안겼던 지카 바이러스(Zika virus)와 최근 아열대성 기후의 확대로 인해 향후 대유행이 예상되는 뎅기 바이러스(Dengue virus)의 구별 진단 방법에 대해 논의하고자 한다. 두 바이러스는 모두 플라비바이러스 속(Flavivirus genus)에 해당되며, 동일한 단백질 도메인(domain)으로 구성되어 있다. 본 연구에서는 여러 도메인 중에서도 진단에 유리하다고 판단되는 비구조단백질 1(NS1, non-structural protein 1)을 선정하였으며, UniProt (Universal Protein Resource) 데이터베이스를 활용하여 지카 바이러스와 뎅기 바이러스의 비구조단백질 1의 아미노산 서열을 상호 비교 분석 하였다. 더 나아가 IEDB (Immune Epitope Database) 데이터베이스를 활용하여 비구조단백질 1의 아미노산 중, 진단에 용이한 에피토프로 예상되는 5개의 후보를 도출하였다. 최종적으로 후보군으로부터 지카 바이러스와 뎅기 바이러스를 구별하여 진단할 수 있다고 판단되는 에피토프(펩타이드)를 제안하였다.

In recent years, large scale damages from arbovirus infections by mosquitoes have been reported worldwide due to factors such as change in global climate, increased overseas travel, and increased logistics movement between countries. Among them, Zika virus and dengue virus belonging to genus Flavivirus are representative. In this study, we performed in-depth analyses of the envelope (E) protein that perform essential functions for host infection of Zika virus and dengue virus based on bioinformatics databases. The domain analysis of E protein was performed to determine the type, location, and function, and homology analysis for each domain. From these results, EDIII showing low homology was identified. The homology and immunogenicity of each peptide constituting EDIII were analyzed and three-dimensional structures were modeled. Furthermore, we discussed their biological meaning and how they could be used.

Purpose: This study aimed to determine the effect of knowledge and attitudes of preventive behavior plans (PBPs) on Zika virus infection among university students. Methods: Participants included 130 students from H University in Korea. Electronic self-reported questionnaires were used to collect data. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and regression analysis with SPSS/WIN 23.0. Results: The mean percentile score for knowledge was 35.52±20.63. The mean scores for attitudes and PBPs were 3.31±0.47 and 3.07±0.72, respectively, out of 5 points. Knowledge (t=-5.79, p<.001), attitudes (t=-3.17, p=.002), and PBPs (t=-2.67, p=.009) differed significantly with respect to awareness concerning Zika virus infection. The factor 'attitudes' significantly affected PBPs, with an R² value of 12.0% (β=.27, p<.001). Conclusion: Developing a correct attitude toward Zika virus infection may be key to improving preventive behaviors. Health education messages should be tailored to increase preventive behaviors against Zika virus infection. Nursing educators will benefit from partnerships with health educators and by using internet media to speed up the dissemination of Zika virus information.

The Zika virus, a flavivirus related to dengue and Japanese encephalitis was discovered in the Zika forest in Uganda, 1947. Since Zika virus was first reported in Brazil in May 2015, infections have occurred in at least 40 countries, especially in the Americas. Zika virus infection usually is asymptomatic or causes mild illness, but may be related to severe clinical manifestations, particularly microcephaly and Guillain-$Barr{\acute{e}}$ syndrome. Although the possibility of autochthonous Zika virus transmission in South Korea is low, the imported cases and Zika virus-transmitting mosquito should be adequately monitored and promptly managed. In addition, enhancing preparedness for Zika virus infection are needed.

Objective: The outbreak of Middle East Respiratory Syndrome (MERS) started in South Korea in May 2015 and the end of crisis was declared in December 2015 by Korea Centers of Disease Control and Prevention (KCDC). However, Zika virus emerged in less than 2 months following MERS and showed higher mortality than other countries. This study is to assess the current prevention system of overseas infectious diseases, based on MERS and Zika virus outbreak and to suggest effective response system for the future. Methods: We conducted two surveys on medical specialists working at tertiary general hospitals regarding the effectiveness of responding system by KCDC against MERS and Zika virus and education in individual medical institutions using 5-Likert points. Response system was examined in three different periods as initial period, spreading period, and post disease period. Results: Although medical specialists received the notifications in initial period, no practical prevention was proven to be placed in responding stage by medical facilities (averagely 3.5/5 points in total and sub-analyses). During spreading period, there were several academic seminars conducted, which were evaluated as helpful. In post disease period, all answered that there were changes on patient treatment in all medical facilities, with mainly report system and the treatment regulations in case of suspicious patients for infection. Only 49% respondents answered positive on the possibility of initial responses. For questionnaire items regarding Zika virus, all answered that there were notifications prior to the first outbreak of the infected patient. Eighty% of respondents were aware of 'the Guideline system for traveling to dangerous areas', and answered that the system was moderately effective (averagely 3.8/5 points in total). For the effectiveness of prevention measures for foreign novel disease by KCDC, the average point was 3.0 in both of total and sub-analyses. Conclusion: There is not enough response system to prevent infectious disease in medical institutional and governmental levels in Korea. It would warrant the modification of overall medical system to improve preventive measures for initial spread of such diseases.

Recently, global warming has widened the habitat of mosquitoes and infection chances for mosquito-borne diseases are increasing. Flavivirus is a typical mosquito-borne virus. Flaviviruses with a relatively high frequency of infection in Asian countries include Zika, Dengue, and Japanese encephalitis viruses. Although distinctive diagnosis of flaviviruses is required because the symptoms and therapeutic method differ, there is no diagnostic method that can distinguish them accurately yet. In this study, we propose distinctive diagnosis method of flaviviruses using informations and analysis tools constructed in bioinformatic databases. The envelope protein and non-structural protein 1 which are useful protein for the immuno-diagnostics of three flaviviruses were selected. Their homology was analyzed by multiple sequence alignments and epitope candidates consisting of 10-15 amino acids were selected. Finally two epitopes were suggested to be most useful by immunogenicity analysis and 3D structure prediction. These approaches and results are expected to be great value in the distinctive diagnosis of three flaviviruses with a high frequency of infection in Asian countries.

This survey was performed to monitor the spread of specific mosquito-borne pathogens at Jeonbuk. The frequency of occurrence of mosquito borne pathogens including Japanese encephalitis virus, West Nile virus, Zika virus, and yellow fever virus was assessed by collecting mosquitoes twice a month from March to December 2021 from various areas in Jeonbuk. A total of 15,975 mosquitoes from 15 species and 7 genera were collected. The highest number of 9,116 mosquitoes (trap index: TI, 506.4) were collected in the Wanju cattle pen, followed by the habitat for migratory birds and the downtown area in Jeonju. In the Gunsan habitat for migratory birds, 3,217 mosquitoes (TI, 178.7) were collected in the reed fields, 356 (TI, 19.7) in the men's toilets, and 1,948 (TI, 108.2) in the women's toilets. In Jeonju, 677 mosquitoes (TI, 37.6) were collected in the Deokjin park, 358 (TI, 19.8) in the Deokjin-gu office, and 303 (TI, 16.8) at the Jeonbuk National University. The largest population of mosquitoes was collected in the men's toilets in Gunsan and the Deokjin Park in downtown Jeonju. The results of the RT-PCR confirmation to determine the pathogen infection of the collected mosquitoes were all negative. These results provide a basis for tackling integrated mosquito-borne diseases in the Jeonbuk region.
