선거기간이 되면 많은 여론조사 기관에서 후보자별 지지율을 조사하여 배포한다. 과거에는 여론조사 기관에 의존하여 지지율을 조사할 수밖에 없었지만, 현대 사회에서는 인터넷이나 모바일 SNS나 커뮤니티를 통해 국민 여론이 표출된다. 따라서 인터넷상에 표출된 국민 여론을 자연어 분석을 통해서 파악하면 여론조사 결과만큼 정확한 후보자 지지율을 파악할 수 있다. 따라서 본 논문은 인터넷 커뮤니티 게시글 데이터를 통해 유저들의 정치 관련 언급을 종합하여 선거기간 후보자의 지지율을 추론하는 방법을 제시한다. 게시글에서 지지율을 분석하기 위해 KoBert, KcBert, KoELECTRA모델을 활용하여 실제 여론조사와 가장 상관관계가 높은 모델 생성 방법을 제시하고자 한다.

Microbial community profiling using 16S rRNA amplicon sequencing allows for taxonomic characterization of diverse microorganisms. While amplicon sequence variant (ASV) methods are increasingly favored for their fine-grained resolution of sequence variants, they often discard substantial portions of sequencing reads during quality control, particularly in datasets with large number samples. We present a streamlined pipeline that integrates FastP for read trimming, HmmUFOtu for operational taxonomic units (OTU) clustering, Vsearch for chimera checking, and Kraken2 for taxonomic assignment. To assess the pipeline's performance, we reprocessed two published stool datasets of normal Korean populations: one with 890 and the other with 1,462 independent samples. In the first dataset, HmmUFOtu retained 93.2% of over 104 million read pairs after quality trimming, discarding chimeric or unclassifiable reads, while DADA2, a commonly used ASV method, retained only 44.6% of the reads. Nonetheless, both methods yielded qualitatively similar β-diversity plots. For the second dataset, HmmUFOtu retained 89.2% of read pairs, while DADA2 retained a mere 18.4% of the reads. HmmUFOtu, being a closed-reference clustering method, facilitates merging separately processed datasets, with shared OTUs between the two datasets exhibiting a correlation coefficient of 0.92 in total abundance (log scale). While the first two dimensions of the β-diversity plot exhibited a cohesive mixture of the two datasets, the third dimension revealed the presence of a batch effect. Our comparative evaluation of ASV and OTU methods within this streamlined pipeline provides valuable insights into their performance when processing large-scale microbial 16S rRNA amplicon sequencing data. The strengths of HmmUFOtu and its potential for dataset merging are highlighted.

최근 MRSA와 같은 항생제 내성 균주에 감염되는 사례가 점점 증가하는 추세이며, 특히 원내에서 감염되는 경우도 상당수 찾아볼 수 있다. 본 연구에서는 강원에 소재한 대학에 재학생들을 대상으로 병원 실습 경험 여부를 조사하고, 각각 비강 검체를 채취하여 황색포도알균인 Staphylococcus aureus 균주 및 MRSA (methicillin resistant Staphylococcus aureus)의 존재 여부를 동정하여 임상 실습 경험이 있는 학생과 MRSA 검출에 대한 관계를 확인하고자 하였다. 실험에 참여한 인원은 64명 학생으로 남학생 22명, 여학생 42명이다. 멸균된 면봉으로 비강 검체를 채취하여 수송 배지인 Thioglycollate broth로 수송한 뒤, 선택배지인 MSA(mannitol salt agar)에 접종했다. 균을 배양하여 다양한 생화학적 test 및 상용화 키트인 API Kit를 사용하여 분리 및 동정을 하였고, 최종으로 분자생물학적 방법을 사용하여 MRSA 검출 양상을 확인하였다. 64명 학생 중 Staphylococcus aureus 균주가 46명에서 검출되었으며, 46명의 검체 중에 22명에서 MRSA가 검출되었다, 22명의 학생 중에 남학생은 5명, 여학생은 17명이었으며, 15명의 학생은 최근 1년 이내에 입원, 수술력 또는 임상현장실습 등의 의료기관 관련 MRSA(HR-MRSA)로 확인되었고, 나머지 7명(%)은 CA-MRSA로 확인되었다. MRSA가 검출된 학생들의 감염경로를 확인한 결과, 평상시 의료기관 방문 여부와 임상 실습경험 등으로 비추어 볼 때 원내에서 감염되었다고 추정할 수 있으며, 임상실습에 참가하는 학생들을 대상으로 원내 감염 예방을 위한 추가적인 교육과 학생들의 적극적인 참여가 필요하다고 여겨진다.

There has been a dramatic increase in the popularity of utilizing social media data for research purposes within the biomedical community. In PubMed alone, there have been nearly 2,500 publication entries since 2014 that deal with analyzing social media data from Twitter and Reddit. However, the vast majority of those works do not share their code or data for replicating their studies. With minimal exceptions, the few that do, place the burden on the researcher to figure out how to fetch the data, how to best format their data, and how to create automatic and manual annotations on the acquired data. In order to address this pressing issue, we introduce the Social Media Mining Toolkit (SMMT), a suite of tools aimed to encapsulate the cumbersome details of acquiring, preprocessing, annotating and standardizing social media data. The purpose of our toolkit is for researchers to focus on answering research questions, and not the technical aspects of using social media data. By using a standard toolkit, researchers will be able to acquire, use, and release data in a consistent way that is transparent for everybody using the toolkit, hence, simplifying research reproducibility and accessibility in the social media domain.

Objectives: Legionnaires' disease (LD) is a severe type of pneumonia caused by inhalation of aerosols contaminated with Legionella. On September 22, 2016, a single case of LD was reported from a newly built apartment building in Gyeonggi province. This article describes an epidemiologic investigation of LD and identification of the possible source of infection. Methods: To identify the source of LD, we interviewed the patient's husband using a questionnaire based on the Legionella management guidelines from the Korea Centers for Disease Control and Prevention. Water samples from the site were collected and analyzed. An epidemiological investigation of the residents and visitors in the apartment building was conducted for 14 days before the index patient's symptoms first appeared to 14 days after the implementation of environmental control measures. Results: Legionella pneumophila serogroup 1 was isolated from the heated-water samples from the patient's residence and the basement of the apartment complex. Thirty-two suspected cases were reported from the apartment building during the surveillance period, yet all were confirmed negative based on urinary antigen tests. Conclusions: The likely source of infection was the building's potable water, particularly heated water. Further study of effective monitoring systems in heated potable water should be considered.

High speed all optical network is a viable option to satisfy the exponential growth of internet usage in the recent years. Optical networks offer very high bit rates and, by employing technologies like internet protocol over wavelength division multiplexing(IP-over-WDM), these high bit rates can be effectively utilized. However, failure of a network component, carrying such high speed data traffic can result in enormous loss of data in a few seconds and persistence of a failure can severely degrade the performance of the entire network. Designing IP-over-WDM networks, which can withstand failures, has been subject of considerable interest in the research community recently. Most of the research is focused on the failure of optical links in the network. This paper addresses the problem of designing IP-over-WDM networks that do not suffer service degradation in case of a single link failure. The paper proposes an approach based on the framework provided by a recent paper by M. Kurant and P. Thiran. The proposed approach can be used to design large survivable IP-over-WDM networks.
