스포츠센터 이용자의 소비자 행동에 관한 구조적 관계 연구
권아연 ( Ayeon Kwon ),최승재 ( Seungjae Choi ) 아시아문화학술원 2019 인문사회 21 Vol.10 No.3
본 연구는 스포츠센터 이용자의 이용 원인과 소비자 행동의 관계를 검증하고 서비스 품질과 스포츠 시설이 어떠한 영향을 미치는지를 검증하고자 하였다. 이러한 연구를 위하여 전라남도에 소재한 스포츠센터 이용자를 대상으로 2019년 3월 20일부터 4월 20일까지 설문조사를 실시하였고, 250명의 회수된 설문지를 대상으로 통계 분석하였다. 실증분석은 빈도분석, 요인분석, 타당도분석, 경로분석, 매개효과분석을 실시하여 결과를 제시하였다. 첫째, 스포츠이용 원인은 서비스 품질과 스포츠 시설에는 영향이 있는 것으로 나타났다. 하지만, 스포츠이용 원인은 소비자 행동에 영향이 없는 것으로 나타났다. 둘째, 스포츠이용 원인과 소비자 행동은 간접적인 영향이 있는 것으로 나타났다. 서비스 품질은 스포츠이용 원인과 소비자 행동에 매개역할을 하는 것으로 나타났고, 스포츠 시설은 스포츠이용 원인과 소비자 행동에 매개역할을 하는 것으로 나타났다. 향후에는 소비자의 재이용과 타인추천 행동 모색을 위한 연구가 이루어져야 할 것이다. 이러한 연구로 스포츠센터가 생활에 밀접한 문화로 접근하여 국민의 여가와 삶의 질 향상에 도움이 되는 시설로 재생산되길 기대한다. The purpose of this study is to verify the relationship between Cause of Sports Use and consumer behavior and to examine the role of service quality and sports facilities in sports center users. For this study, a questionnaire survey was conducted from March 20 to April 20, 2019 for sports center users in Jeollanam-do, and 250 questionnaires were analyzed. Empirical analysis was conducted by frequency analysis, factor analysis, validity analysis, path analysis, and mediating effect analysis. First, it was found that the use of sport affects service quality and sports facilities. However, Cause of Sports Use did not affect consumer behavior. Second, Cause of Sports Use and consumer behavior have indirect effects. Service quality has a mediating role in sport use and consumer behavior, and sports facilities have mediating role in sport use and consumer behavior. Through these studies, it is expected that the sports center will approach the culture closely to life and be reproduced as a facility that will help improve the leisure and quality of life of the people

의료 관련 질의응답을 위한 BERT 기반 한국어 QA 모델
권세린(Serin Kwon),정성현(Seonghyeon Jeong),정아연(Ayeon Jeong),조영진(Yeongjin Jo),김지희(Jihie Kim),김광일(Kwangil Kim) 한국정보기술학회 2022 Proceedings of KIIT Conference Vol.2022 No.6
Question Answering(QA)는 자연어 처리 분야에서 활발하게 연구가 되고 있는 주제이다. 따라서 본 연구에서는 ‘질병과 건강’이라는 특정 도메인에 대한 질의에, 자동적으로 답안을 제시하는 한국어 QA 모델을 제시한다. QA 시스템에서는 기존의 KoBERT 시퀀스 모델을 활용했으며, fine-tuning을 위해 KorQuAD 데이터와 질병관리청에서 제공하는 데이터를 KorQuAD 형식으로 수기로 변환한 데이터를 사용했다. 본 연구에서 제안하는 모델은, 기존의 KoBERT 모델과 비교 했을 때, F1 score은 77.49 그리고 Exact Match는 75.00이라는 향상된 성능을 보였다. Question Answering (QA) is a topic that is being actively researched in the field of natural language processing. Therefore, in this study, we propose a Korean QA model that automatically provides answers to questions about a specific domain called ‘disease and health’. In the QA system, we use the existing KoBERT sequence model, and for fine-tuning, KorQuAD data and data provided by the Korea Centers for Disease Control and Prevention were manually converted into KorQuAD format. Compared with the existing KoBERT model, the model proposed in this study showed improved performance with an F1 score of 77.49 and an Exact Match of 75.00.

Immunomodulating activities of prebiotics-producing lactic acid bacteria strains
Seoyoung Jeong,Chaeeun Lee,Ayeon Kwon,Young-Seo Park 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10
Prebiotics serve as nutrients for probiotics and strengthen the probiotic properties. The probiotic properties and immunomodulating activities of three prebiotics-producing lactic acid bacteria strains, Leuconostoc lactis CCK940, L. lactis SBC001, and Weissella cibaria YRK005, were investigated. Three strains survived in acid and bile acid environments as well as produced antioxidants. All strains showed high adhesion abilities to human colon cancer cell line, HT-29. Three strains had no cytotoxicity against RAW264.7 macrophages at the cell number ratio of bacteria to macrophages (MOI) of 100. When macrophages were treated with three strains, the production of nitric oxide increased in concentration-dependent manner. When macrophages were treated with three strains, the mRNA expression levels of TNF-α in macrophages increased and those of iNOS were similar to those in LPS-treated cells at MOI 100, which were identified by qPCR. The expression of P38, ERK, and JNK, which identified by western blot, increased in macrophages treated with strains CCK940 and SBC001. These results indicated that three strains showed high immunostimulating activities through MAPKs signaling pathway.

In this study, electrically conductive materials composed of carboxylated polypyrrole (PPy(COOH)) andnontoxic oligosaccharide molecules (cyclodextrin, CD) were prepared and incorporated intobiocompatible hydrogels for use as versatile sensors. The major component, carboxylated polypyrrolenanotubes (PPy(COOH) NTs) were fabricated using microemulsion polymerization and a critical sensingmedium CD molecule was introduced via a simple surface engineering method. The resulting PPy(COOH)-CD NT hybrid complexes were incorporated into a hydrogel matrix for biocompatibleapplications. Consequently, a convenient sensor geometry was constructed by mounting the hydrogelon a gold micropattern for the detection of toxic substances. The feasibility of the produced sensor systemwas demonstrated, and the sensor performance was measured extensively using electrical measure-ments. It was found that the sensor could detect a model compound (methyl paraben, MPRB) atconcentration as low as 1 nM. This study provides useful information for future research activities inrelevantfields.
