일개 종합병원의 조기대응팀의 활동에 사용되는 스크리닝 시스템의 유용성
주혜진,박소희,홍상범,임채만,고윤석,이영석,허진원 대한중환자의학회 2012 Acute and Critical Care Vol.27 No.3
Background: Rapid response team (RRT) is becoming an essential part of patient safety by the early recognition and management of patients on general hospital wards. In this study, we analyzed the usefulness of screening criteria of RRT used at Asan Medical Center. Methods: On a retrospective basis, we reviewed the records of 675 cases in 543 patients that were managed by RRT (called medical alert team in the Asan Medical Center), from July 2011 to December 2011. The medical alert team was acted by requests of attending doctors or nurses or the medical alert system (MAS) criteria composed of abnormal vital sign, neurology, laboratory data and increasing oxygen demand. We investigated the patterns of MAS criteria for targeting the patients who were managed by the medical alert team. Results: Respiratory distress (RR > 25/min) was the most common item for identifying patients whose condition had worsened. The criteria consist with respiratory distress and abnormal blood pressure (mean BP < 60 mmHg or systolic BP < 90 mmHg) found 70.0% of patients with deteriorated conditions. Vital sign (RR > 25/min, mean BP < 60 mmHg or systolic BP < 90 mmHg, pulse rate, PR > 130/min or < 50/min) and oxygen demand found 79.2% of them. Vital signs, arterial blood gas analysis (ABGA) with lactate level (pH, pO2, pCO2, and lactate) and O2 demand found 98.6% of patient conditions had worsened. Conclusions: Vital signs, especially RR > 25/min is useful criteria for detecting patients whose conditions have deteriorated. The addition of ABGA data with lactate levels leads to a more powerful screening tool.

모바일기기에서 바이오인식정보와 OTP를 이용한 본인인증기법
주혜진,윤보미,전명근 한국경영정보학회 2014 한국경영정보학회 학술대회논문집 Vol.2014 No.1
스마트기기에서 스마트뱅킹, 인터넷쇼핑, 비접촉거래 등의 지급결제 거래가 급증함에 따라 모바일 OS의 취약점, 인증서 오남용 문제 등의 보안상의 문제가 대두되며, 이에 대처할 수 있는 강력한 개인 인증 수단이 요구된다. 이와 같은 상황에 대처하기 위한 인증 수단으로 바이오인식정보와 더불어 PKI를 이용한 OTP를 적용하고자 한다. 바이오인식정보는 분실이나 도용의 위험이 적으며 OTP를 이용한다면 바이오인식정보만을 이용할 때 보다 보안성이 강화될 수 있다. 이에 본 논문에서는 모바일 기기에서 바이오인식정보와 시간동기화 OTP를 이용한 개인 인증 기법을 제안한다.

대전은 어떻게 ‘노잼도시’가 되었나 : 텍스트 마이닝과 의미 연결망으로 본 ‘장소성’ 소비
주혜진 한국사회학회 2022 韓國社會學 Vol.56 No.4
This study explores how ‘Snoozefest Daejeon’ has been created on social media platforms by employing Big Data analysis (text mining and semantic network analysis). In this work, the texts from 5,875 blogs during 2015-2021 were collected by Python to locate keywords(nodes), topics, and the structural network of words. KoNLPy(Korean morpheme analyzer tool) extracted nouns, proper nouns, adjectives, and verbs to perform the natural language process. Before 2019, the word No-Jam, roughly translated to English as ‘snoozefest,’ was mainly used to depict boring movies, games, or people but had no relation to Daejeon City. TF-IDF scores revealed that since 2019 Daejeon City has been the feature term of ‘snoozefest city.’ The TF-IDF evaluated the importance of the term Daejeon in massive documents. LDA(Latent Dirichlet Allocation) modeling determined the number of topics as eight for blogs. Blog text focused more on personal sentiment and experience based on daily active accounts. LDA revealed that blog users wanted to go to attractive cafes to enjoy their specific ambiance and later show off the experience by posting photos. The top feature words with high TF-IDF scores also supported the trend. PageRank centrality analysis and network clustering(CONCOR) also demonstrated that the story of ‘visiting Daejeon City’ significantly led to other themes in the blog text. People traveled to the snoozefest place, Daejeon City, and found unexpected or hidden fun at a specific place, a cafe, but not specific to its locality. Like Azuma Hiroki’s term “database consumption,” this travel culture differed greatly from classic touring, experiencing the historical and cultural narrative. Semantic Network Analysis also proved people consumed a single element of snoozefest place, treating Daejeon as a meme. The snoozefest Daejeon’s status as a meme was iterated by messages, which the blog users—from ‘hipster wannabe’ culture—had rapidly spread to continue the conversation with each other. As a ‘media ritual,’ this consumption trend shows the weak relation between humans and place. Daejeon’s database consumption makes people lose not only the chance to interact with the place but also the sense of place.

Comorbidities of Chronic Obstructive Pulmonary Disease in Koreans: A Population-Based Study
주혜진,박진경,이상도,오연목 대한의학회 2012 Journal of Korean medical science Vol.27 No.8
Chronic obstructive pulmonary disease (COPD) includes pulmonary components with increased comorbidity rates, as well as being a systemic disease. Comorbidities may frequently occur in COPD patients over 40 yr old. We report the comorbidities of patients with COPD, diagnosed by spirometry, in a population-based epidemiologic survey in Korea. Data were derived from the fourth Korean Health and Nutrition Examination Survey in 2008, a stratified multistage clustered probability design survey of a sample representing the entire population of Korea. Results of spirometry and various health-related questionnaires were analyzed in 2,177 subjects aged ≥ 40 yr. The prevalence of COPD (FEV1/FVC < 0.7) in subjects ≥ 40 yr of age was 14.1%. Multivariate analysis showed that underweight (odds ratio [OR] 3.07, 95% confidence interval [CI] 1.05-8.98), coronary heart disease (OR, 0.43; 95% CI, 0.20-0.93) and dyslipidemia (OR, 0.61; 95% CI, 0.45-0.82) were significantly associated with COPD, whereas allergic rhinitis, anemia, arthritis,chronic renal failure, depression, diabetes mellitus, hypertension, gastrointestinal ulcer,and osteoporosis were not. Underweight might be more prevalent but coronary heart disease and dyslipidemia are less prevalent in Koreans with than without COPD in population setting.
