Cross-national Ongoing Crisis Communication Using Social Media
Young Kim,Myoung-Gi Chon,Andrea Miller 한국언론학회 2014 Asian Communication Research Vol.11 No.1,2
The purpose of this study is to help fill a gap in research that examines sustained cross-national crisis communication using social media. Using the 2013 Asiana Airlines crash crisis, a content analysis was conducted, analyzing the airlines’ 1,685 tweets and 1,386 public’s responses in terms of type of tweets, message strategies and publics’ emotions, communication tools (text, video, photo, hyperlinks, #hashtag, and conversation), and message tones. During the crisis, the organization used the same crisis response, a very passive response, as the US and Korean publics. As a result, the crisis response affected different emotions of the publics based on culture; the US publics felt anger and presented a more negative tone than the Korea publics did. Further, the US and Korean Twitter were utilized differently over the duration of the crisis according to. Thus, the findings demonstrate the importance of sustained crisis communication before, during, and post-crisis and the inevitable effect of culture on crisis communication. This study therefore aims to offer theoretical and practical implications in social media crisis communication by providing researchers and crisis managers with a more comprehensive and realistic picture that considers the entire crisis cycle as well as cultural differences .

Objective: Contact investigation with Tuberculin Skin Test (TST) and delayed QuantiFERON testing (QFT) had been conducted against continued tuberculosis (TB) outbreaks in a high school before Korea latent TB infection (LTBI) policy establishment. We investigated the aftereffect of confirmatory QFT added to positive TST. Methods: We reviewed the outbreaks courses, and identified the TB development in relation to initial TST and QFT with the aid of Korean national claims database. Results: Continued sequential 43 active TB cases were diagnosed in a high school for one year before LTBI investigation. After contact investigation, a total of 925 contacts were divided into three groups: TST- (n=632), TST+/QFT+ (n=25), TST+/QFT- (n=257). The mean duration of follow-up was 3.9 ± 0.9 years. QFT- was more prevalent compared with QFT+ in contacts with 10mm ≤ TST <15mm (157, 61.1%) than in contacts with TST ≥15mm (100, 38.9%) among the TST positive reactors (Odds ratio 4.97, C.I: 1.80 - 14.46, P < 0.001). Of the 257 TST+/QFT- subjects, 255 received no LTBI treatment, and 7 contacts developed TB during follow-up. Among these 7 patients, four had initial TST ≥15mm, and three 10mm ≤ TST <15mm. Conclusions: The delayed contact investigation for LTBI in a high school TB outbreak brought upon the continuous successive TB outbreaks. False negative QFT performed lately among the TST positive reactors should not be considered as a criteria for LTBI treatment. Additionally, the contacts only with strong induration size of TST (≥ 15mm) should be considered for LTBI treatment.

Purpose: There are many somatic mutations in lung cancer, and many biological processes that cause mutations in somatic cells leave a mutational signature. The purpose of this study is to identify the mutational signature according to the stage of lung adenocarcinoma in Korea. Methods: A total of 103 specimens from patients diagnosed with lung adenocarcinoma were obtained and NGS based repeated deep sequencing was performed. The single nucleotide variation detected by the test was converted to maf.file and mutational signatures according to the stage of lung cancer analyzed by applying a computational framework for mutational signature model proposed by Alexandrov et al. The mutational signature nomenclature is that used in the Catalogue of Somatic Mutations in Cancer (COSMIC). Results: As a result of mutational signature analysis with stage I lung cancer, signature 5 (cosine similarity=0.656, unknown etiology) was the most significant result. With stage II lung cancer, signature 7 (cosine similarity=0.742, UV exposure) was the most significant result and with stage III lung cancer, signature 30 (cosine similarity=0.777, unknown etiology) was the most significant result. In this study, the number of patients with stage IV lung cancer was small and there were no significant results. Conclusions: The risk factors for lung cancer other than smoking,the exact cause has not been clarified, they are presumed to have left a mutational signature. In addition, the mutational signatures according to the stage of lung adenocarcinoma in Korean patients showed different result.

Abdominal obesity is considered as one of the most risky factors governing the development of metabolic diseases. Here we identify that human chitinase 3-like 1 (CHI3L1, also called YKL-40 in human) single nucleotide polymorphism (SNP), rs883125, is associated with abdominal obesity in Korean women. Korean women subjects with the rs883125 G/G or C/G genotype present higher waist-hip ratio than subjects with C/C genotype suggesting that human subjects who G nucleotide substitution at the rs883125 tended to more accumulate intra-abdominal fat at the abdominal cavity. In addition, Chi3l1 gene expression is increased in adipose tissue from obese mice and pro-inflammatory cytokine enhances Chi3l1 expression in adipocytes, indicating that Chi3l1 is greatly related with obesity and obesity-induced pro-inflammatory responses. Taken together, the minor allele of rs883125 is associated with a higher prevalence of abdominal obesity in Korean women. These findings suggest that genotype of rs883125 can be a biomarker of incident abdominal obesity and abdominal obesity-related metabolic diseases.

이리응애과의 많은 종들은 잎응애, 총채벌레 및 가루이와 같은 미소 해충의 생물학적 방제원으로 이용가능성이 높다. 실제로 칠레이리응애와 같은 포식활동이 왕성한 일부 종은 현재 농업에서 전세계적으로 많이 이용되고 있다. 특정 지역이나 생태계 또는 작물에 서식하는 이리응애과의 다양성 조사는 포식성 이리응애의 활용을 위한 좋은 기초자료가 된다. 그러나 국내에서 이와 관련된 자료는 90년대에 1건에 그쳐 자생 이리응애의 활용을 위한 후속 연구를 도모하기에 턱없이 부족한 실정이다. 본 연구에서는 중부지역의 6개도 17개 시군에서 2018년 7월부터 10월까지 자생 이리응애의 발생상황을 조사하였다. 그 결과 총 29과 57종의 식물종에 서식하는 20종의 이리응애를 확인하였다. 다양한 이리응애가 서식하는 식물종은 벚나무로 긴꼬리이리응애를 포함한 6종이 출현하였다. 서식 식물종이 가장 많은 이리응애는 긴꼬리이리응애로 17종이 식물에서 출현했고, 두 번째는 긴털이리응애로 16종의 식물에서 발견되었다.
