확산 모델을 이용한 악취배출허용기준 개선 필요성 연구

윤희영,구윤서 한국냄새환경학회 2013 실내환경 및 냄새 학회지 Vol.12 No.2

Even though offensive odor control law was enforced in 2005, the civil appeal of odor doesn't decrease all parts of the country. On Effluent Quality Standard site, the reason why the civil appeal is filed could be the restriction which is regulated by odor concentration(dilution threshold) without considering odor emission. When regulating odor concentration only, the different scenarios were considered and analyzed for diffuse form through odor concentration, stack height and flow rate using AERSCREEN. Odor compounds from the analyzed scenarios were fluctuated by not only odor concentration but flow rate. Therefore, flow rate regulation introduction is necessary because odor concentration regulation of Effluent Quality Standard doesn't make the civil appeal reduce. Now, Odor Effluent Quality Standard is managed by Effluent Quality Standard like air pollutants in Korea. It means, the concept conversion of Receptor-centric is need for preventing civil appeal and complaint of odor. For the odor management of receptor-centric, workplace emission is regulated in accordance with odor concentration at receptor. but it's hard to regulate all of workplace respectively because all workplace condition is different each other. In Japan, odor diffusion modeling for calculating the causal relationship between receptor and emission is used for the method to figure out the problem. By expanding odor automatic monitoring network that some of local governments have, odor emission management and continues receptor current status analysis are needed to combine and operate for resolving odor problem. 2005년부터 악취방지법이 시행되었음에도 불구하고 전국의 악취 민원이 감소하지 않고 증가하고 있다. 민원 발생의 증가는 다양한 원인이 있겠지만 배출허용기준 측면에서 본다면, 악취의 규제기준이 배출량을 고려하지 않고 악취농도(희석배수)로만 규제하고 있는 제한점 때문인 것으로 볼 수 있다. 악취농도만 규제할 경우의 확산 형태를 보기 위해 AERSCREEN을 이용하여 악취농도, 배출구높이, 배출유량을 달리하여 시나리오를 설정하고 최대착지거리와 악취농도를 분석․검토 하였다. 시나리오 분석을 통해 확산된 악취물질은 악취발생농도 뿐만 아니라 배출유량에 의해 좌우됨을 알 수 있었다. 따라서 현행 악취배출허용기준의 악취농도규제만으로는 민원 발생을 차단할 수 없고, 배출유량 규제의 도입이 필요하다. 이는 현재 국내 악취배출허용기준이 일반 대기오염물질과 동일한 개념을 적용하여 배출원 규제기준의 달성여부 관점에서 운영되고 있는 것은 적합하지 않으며, 수용체 중심으로 민원 및 불만을 야기시키지 않도록 하는데 중점을 두는 것으로 관점의 전환이 필요함을 의미하는 것이다. 수용체중심의 악취관리를 위해서는 수용지점에서 농도기준(부지경계기준)을 만족하기 위한 사업장 악취배출량을 규제해야 한다. 그러나 악취배출 사업장의 조건은 다양하므로 일괄적인 규제는 어렵다. 이를 해결하기 위해 일본과 같이 수용체와 배출원과의 인과관계를 계산하기 위한 악취확산모델링이 해법이 될 수 있다. 또한 현재 일부 지자체에서 운영하고 있는 악취자동측정망을 확대하여 악취배출원 관리와 더불어 지속적으로 수용체에서 악취의 현황을 파악하여 악취 문제를 해결하는 것이 병행될 필요가 있다.

Background: The use of QT-prolonging drugs, especially combined use of bedaquiline (Bdq) and delamanid (Dlm), is a hot issue in the treatment of MDR-TB. Methods: We reviewed 373 patients (mean age: 56.4 years, male: 51%, mean treatment duration: 76.8 weeks) with MDR-TB or NTM disease, treated with clofazimine (Cfz), moxifloxacin (Mfx), Bdq, Dlm, or macrolides over a month. Any cardiac adverse events (AEs) or death were evaluated. Among 60 patients (16%) with serial EKGs results, baseline QTcF interval and QTcF interval changes were evaluated. Results: 165 (44%), 315 (84%), 10 (3%), 229 (61%) and 1 patients received Cfz, Mfx, Bdq, macrolides and Dlm, respectively. 193 (52%) and 77 (21%) patients received two and three QT-prolonging drugs, respectively. Nine (2.4%) patients were lost to follow up during treatment: 5 were alive as of July 2016, 1 dead 2 years after treatment completion, and in remaining 3 patients, clinical courses were unknown. In remaining 364 patients, 4 (1.1%) cardiac AEs (cardiac tamponade due to TB pericarditis, atrial fibrillation, sinus tachycardia, cardiac arrest) were documented but none were related with QT-prolonging drug uses. Two patients discontinued medication due to QTcF prolongation (550 msec and 534 msec), without any clinical events. Mean baseline QTcF was 419 msec and mean increase of QTcF to maximum value was 33.6 msec. Significant QTcF changes (QTcF ≥ 500 msec or increase ≥ 60 msec) were observed in 9 (15.0%) patients. Conclusions: The use of QT-prolonging drugs, frequently used in combination, was generally safe in MDR-TB or NTM patients

윤희영,문수현,엄성용 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.3

This paper describes a mobile application that can recognize and identify cats residing on a university campus using the Google’s machine learning platform, ‘Teachable Machine’. Machine learning, one of the core technologies of the Fourth Industrial Revolution, performs an efficient task of finding optimal results through data learning. Therefore, the model is learned and generated using the platform based on machine learning, and then implemented as an application for smartphones, so that cats can be identified simply and efficiently. In this application, if you take a picture of a cat directly on the spot or call it from the gallery, the cat is identified and information about the cat is provided. Though this system was developed for a specific university campus, it is expected that it can be extended to other campuses and other species of animals. 본 논문은 구글의 머신러닝 플랫폼인 ‘티처블 머신’을 이용해 대학 캠퍼스내 상주하는 고양이들을 인식하고 식별할 수 있는 모바일 애플리케이션에 대해 설명한다. 4차 산업혁명의 핵심 기술 중 하나인 머신러닝은 데이터 학습을 통해 최적의 결과값을 찾아내는 효율적인 작업을 수행한다. 따라서 머신러닝을 기반으로 동작하는 ‘티처블 머신’ 플랫폼을 이용해 모델을 학습, 생성한 뒤 이를 스마트폰용 애플리케이션으로 구현하여, 간편하고 효율적으로 고양이들을 식별할 수 있게 하였다. 이 애플리케이션에서는 고양이의 사진을 현장에서 직접 찍거나 갤러리에서 불러오면 해당 고양이를 식별하여 그 고양이에 대한 정보를 제공한다. 본 시스템은 특정 대학 캠퍼스용으로 개발되었지만, 타 대학 캠퍼스 및 다른 종의 동물에 대해서도 확대 적용 가능할 것으로 기대한다.

윤희영,고의원,이석현,하세진,류진숙,김동순,송진우 대한결핵 및 호흡기학회 2017 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.124 No.-

Objectives: Several biomarkers have been reported to be useful in assessing disease severity of idiopathic pulmonary fibrosis (IPF); however, the role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG/PET-CT) is not well defined. The aim of study was to investigate the value of 18F-FDG PET/CT for assessing disease severity in IPF Methods: Clinical data were retrospectively reviewed in 89 IPF patients (mean age: 68.1 years, male: 94%) who performed 18F-FDG PET/CT for cancer evaluation at Asan Medical Center, Seoul. Standardized uptake value (SUV) was measured only in fibrotic area, and lesion-to-liver SUV ratio (SUVR) was also obtained. Correlation between 18F-FDG PET/CT parameters (SUV and SUVR) and clinical parameters including lung function, exercise capacity, and GAP index were analyzed. Results: Median follow-up period was 11.9 months and lung cancer was confirmed in 61 (69%) patients. SUV and SUVR were significantly correlated with forced vital capacity (r=-0.214, r=-0.275, respectively), diffusing capacity for carbon monoxide (r=-0.375, r=-0.373), distance (r=-0.297, r=-0.318) and the lowest oxygen saturation (r=-0.255, r=-0.339) during 6-minute walk test, and GAP index (r=0.343, r=0.321). SUV were also significantly correlated with decline in total lung capacity after 6 months (r=-0.501). SUVR was predictor for death (hazard ratio [HR]: 1.466; 95% confidential index: 1.009-2.131; p=0.045) on univariate analysis Conclusions: Our findings suggest that 18F-FDG PET/CT may be useful to assess disease severity in patients with IPF.

Pulmonary Alveolar Proteinosis in Korea : Analysis of Prevalence and Incidence by a Nationwide Population-based Study

윤희영,김예지,송진우 대한결핵 및 호흡기학회 2018 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.126 No.-

Objectives: Pulmonary alveolar proteinosis (PAP) is a rare lung disease, but its prevalence and incidence of PAP are not well defined. We investigated the prevalence and incidence of PAP by using nationwide claims data from Korean health insurance review and assessment service. Methods: Cases of PAP were identified for any visit between 2010 to 2016 that listed the Korean Classification of Disease, 7th edition code of PAP (J84.0) and rare incurable disease exempted calculation code (V222). A narrow case definition was defined as follows: 1) more than two PAP-coded visits within 1 year of the first claim, 2) more than one claim for both chest computed tomography and diagnostic procedures (bronchoscopy or surgical lung biopsy) within 90 days of the first claim. Results: A total of 182 patients (narrow, n=82) visited medical institutions for PAP during the study period, and 89 patients (narrow, n=66) were newly identified between 2012 and 2016. The 7-years prevalence of PAP was 4.44 (narrow: 2.27) per 106 people. The incidence rate was 0.56 (narrow: 0.41) per 10⁶ population at risk. The highest incidence peak in men and women were 50-59 years, but women showed bimodal age distribution due to the second incidence peak in 20-29 years. For incidence cases, mean age was 50.8 years, the highest peak age was 50-59 years, and male predominance was observed (male-to-female ratio: 1.82). Conclusions: The prevalence and incidence of PAP in Korea were low, similarly to those in other countries, and middle-aged men showed the highest risk.
