The Republic of Korea has established an air quality monitoring station (AQMS) to manage air quality. Recently, interest in volatile organic compounds (VOCs) emitted from various industrial processes and automobiles has increased worldwide, and it can adversely affect human health. Accordingly, in this study, we measured VOCs at areas adjacent to painting facilities and roadsides in an urban area using a mobile laboratory installed proton transfer reaction time of flight mass spectrometry (PTR-ToF-MS) for a total of 14 times (M1 to M14) for 3 days. The result showed that the concentration of VOCs was higher on weekdays than on weekends and that acetone and methanol were the main components of VOCs at both times. The concentration of benzene was 0.4 ppb, which is below the domestic environmental standard (annual average of 1.5 ppb). In addition, the concentration of VOCs was higher in the sections of nearby road than near the painting facilities, indicating that air quality in urban areas may be impacted more strongly by pollutants from vehicles than by pollutants emitted from workplaces such as painting facilities. Lastly, the study found a stagnant section showing significantly high concentrations of VOCs, for which urgent measures are required to improve air quality.

Buses are one of the most commonly used forms of transportation, and air pollution occurring at the roadside poses a higher health risk than general air pollution. In particular, users of bus-only lanes suffer adverse health effects due to exposure to air pollutants emitted from vehicles running in both directions. This study was conducted on air quality characteristics of an enclosed-type bus station located in Asan City, between 14~24 October, 2022. Pollution levels at the roadside were higher than that of roadside air quality monitoring station (RAQMS), with an exception of carbon monoxide (CO). The average black carbon (BC) concentrations during the measurement period were 2.3±1.1 μg/m3. The average concentration of CO2 inside the enclosed bus station was 987 ppm, which was close to the standards for the maintenance of Indoor Air Quality (IAQ). It was found that pollutant concentrations at the roadside were 1.5 to 2 times higher than the general air pollution level. The result of comparing indoor and outdoor air pollution showed that concentrations of PM10 and PM2.5 outside the enclosed bus station were 1.8 to 2 times higher than that inside. In addition, heavy metal analysis of roadside PM2.5 detected representative soil and mobile pollutants including Si, S, Al, Fe, and Ti. These results show that there is a need for both management and long-term regulatory measures for air pollution at bus stations.

Discourse on the Prostitution Abolition of Japanese Society in Colonial Korea During the 1920s-30s: Focusing on 『Chosen and Manshu(朝鮮及滿洲)』, 『Chosenkoron(朝鮮公論)』

이가혜 한국일본학회 2019 日本學報 Vol.0 No.120

This study looked at the progress of prostitution abolition movement and discourses in Japan, Chosen and Japanese society in colonial Korea to explore the spaces of ‘inland’ and ‘overseas’ and pattern of prostitution abolition discourses according to leading forces. The prostitution abolition movement in ‘inland’ and Chosen took place under the pivotal roles of modern women or Christian groups, etc., and the discourses on it were also produced mainly by each institution’s organ. In the Japanese society in colonial Korea, a series of activities centering on the Japan Christian Women's Organization’s Chosen branch were identified. However, compared with the prostitution abolition movement pursued in Chosen and ‘inland’, these activities were much scaled-down, and no institutional organ was published. In this situation, prostitution abolition efforts were made through general magazines distributed among the public at large, and articulations were not limited to a certain specific value. One thing notable here is that, while there were a lot of news articles on demimonde women’s sexually transmitted disease (STD) checkups throughout the colonial period, there were very few remarks of registered prostitution abolition. This can be interpreted that, instead of prostitution abolition, STD control was more focused on for efficient colony management since it was necessary to install prostitute quarters in Chosen and bring in demimondaines as part of the imperialist expansional policy, and doing so contributed to colonial extension and stabilization. In the substance, the causes of venereal diseases were limited to demimondaines by depicting them as filthy outdated offenders under quarantine, who threaten the ‘healthy people’ to otherize them as the target of control and management of a modern nation. The registered prostitution scheme was also taken as disgrace of a civilized country, and prostitution abolition was discussed for the purpose of national morality promotion and social purification. As indicated, prostitution industry control was claimed solely for the protection of the security of Japanese society in colonial Korea and Japanese empire.

이가혜,김마르다 대한안과학회 2024 대한안과학회지 Vol.65 No.1

목적: 특별한 유발 요인 없이 피눈물을 흘리는 증례를 경험하여 이를 보고하고자 한다. 증례요약: 기저 질환 없는 건강한 19세 남자 환자가 간헐적인 우안 피눈물 흘림을 호소하며 내원하였다. 6년 전부터 1개월에 1회 정도스트레스를 많이 받는 상황에 우안에서 피눈물이 났으며 이때 우안 통증, 안구충혈, 두통, 오심이 동반되었다. 피눈물이 나는 증상은특별한 치료 없이 자연적으로 호전되었다. 우안 교정시력 1.0, 안압은 16 mmHg로 측정되었고 눈 부속기, 눈꺼풀 및 전안부 검진 및코눈물길 더듬자검사 및 관류술상 특이점은 없었으며 안저검사 상에서도 정상 소견을 보였다. 뇌, 안와 자기공명영상촬영에서 뇌, 안와의 이상 소견은 발견되지 않았으나 우측 눈물샘 점막이 경도로 두꺼워져 있었다. 심전도, 흉부 x-ray 검사와 혈액검사, 코내시경검사 모두 정상 소견을 보였다. 결론: 외상력이나 수술력, 기저 질환이 없는 건강한 성인에서 반복적으로 피눈물을 흘리는 증상을 경험하였고, 안과적 검사 및 뇌, 안와 자기공명영상검사에서 특이 소견을 보이지 않아 특발성 피눈물흘림으로 진단하였다. Purpose: To present a case of a patient diagnosed with idiopathic hemolacria. Case Summary: A healthy 19-year-old man without pre-existing medical conditions presented to the hospital for treatment of intermittent bloody tears from his right eye. The patient reported experiencing bloody tears in his right eye approximately once per month during stressful events for the preceding 6 years. These episodes were associated with ocular pain, right-eye hyperemia, headaches, and nausea. However, these symptoms of bloody tears spontaneously resolved without intervention. Corrected visual acuity in the right eye was 1.0, and the intraocular pressure was 16 mmHg. There were no abnormalities in the ocular appendages, anterior chamber, or eyelids. Nasolacrimal duct probing and irrigation, as well as fundus examination, revealed normal findings. Brain and orbital magnetic resonance imaging did not show abnormalities in the brain or the orbital region, although slight mucosal thickening was present around the right lacrimal gland. Other examinations, including an electrocardiogram, chest X-ray, blood test, and nasal endoscopy, all revealed normal findings. Conclusions: Recurrent bloody tears (hemolacria) occurred in the right eye of a 19-year-old man with no history of trauma, intraocular surgery, or underlying medical conditions. Comprehensive ophthalmic examination and brain and orbital magnetic resonance imaging failed to identify any specific abnormalities leading to a diagnosis of idiopathic hemolacria.

儒學視域下的《論佛骨表》小考

이가혜,최영준 한국중국문화학회 2023 中國學論叢 Vol.- No.80

Han Yu was the biggest "opponent" of Buddhism and the pioneer of Neo-Confucianism. Han Yu's famous essay "On the Table of Buddha's Bones" is a well-known anti-Buddha essay in history, in which he fiercely opposes the upcoming sacrificial activity of "welcoming the Buddha's bones" to Emperor Tang Xianzong, and clearly expresses his stance and determination to eliminate Buddha. From the perspective of Confucianism, this paper intends to analyze the opposition and conflict between Confucianism and Buddhism in the Tang Dynasty, including the concept of ethics, the view of the body, the concept of sacrifice, and the education of the people. This article also attempts to analyze the mistakes of Han Yu's distancing of the Tang Dynasty from the perspective of Confucianism, as well as the influence of the "On the Buddha's Bone Table" on later generations.

이가혜,장민욱 대한안과학회 2023 대한안과학회지 Vol.64 No.10

목적: 아트로핀 약물 치료를 시행하는 소아 근시 환자에서 COVID-19 대유행이 아트로핀 치료 효과에 미치는 영향에 대해 연구하였다. 대상과 방법: 근시로 저농도 아트로핀(atropine sulfate 0.01%) 점안 치료를 시행하는 소아 환자들의 12개월간 의무기록을 후향적으로분석하였다. 2013년 7월부터 2020년 1월 사이 아트로핀 약물 치료를 시작하여 12개월 이상 시행한 군과 2020년 2월부터 2021년 7월사이 아트로핀 약물 치료를 시작하여 12개월 이상 시행한 군을 비교하였다. 저농도 아트로핀을 매일 1회 점안하도록 하며 치료 시작시, 12개월 후 우안의 안축장 및 구면렌즈대응치를 측정하였다. 결과: 72명의 환자 중 COVID-19 대유행 이전 아트로핀 치료 시행군(A군)은 34명, 이후 아트로핀 치료 시행군(B군)은 38명이었다. 12개월 동안 저농도 아트로핀 점안 후 굴절이상 변화는 A군에서 -0.58 ± 0.47 diopters (D), B군에서 -0.84 ± 0.56 D (p-value=0.045) 로 두 군 간 유의미한 차이를 보였다. 안축장 변화는 아트로핀 점안 12개월 차에 A군에서 0.30 ± 0.23 mm, B군에서 0.50 ± 0.31 mm로증가하였다(p-value=0.011). 결론: COVID-19 대유행 이후 근시 진행 억제를 위한 저농도 아트로핀 점안 치료 효과가 감소하였다. Purpose: We investigated the impact of the COVID-19 pandemic on myopia progression in pediatric patients who received low-dose atropine (0.01%) eye drops. Methods: We retrospectively analyzed the medical records of pediatric patients who received ≥ 12 months of low-dose atropine (atropine sulfate 0.01%) eye drops for myopia. The beginning of the COVID-19 pandemic was defined as February 2020. Patients were divided into two groups for comparative analysis. Patients in group A received low-dose atropine for ≥ 12 months between July 2013 and January 2020, whereas patients in group B received low-dose atropine between February 2020 and July 2021; atropine eye drops were administered once daily. The spherical equivalent and axial length of the right eye were measured at the initiation of treatment and after 12 months. Results: Among the 72 patients, 34 in group A received low-dose atropine before the COVID-19 pandemic, whereas 38 in group B received low-dose atropine after the COVID-19 pandemic. After 12 months of treatment with low-dose atropine eye drops, the changes in spherical equivalent were -0.58 ± 0.47 diopters (D) in group A and -0.84 ± 0.56 D in group B (p = 0.045). Moreover, the changes in axial length were 0.30 ± 0.23 mm in group A and 0.50 ± 0.31 mm in group B (p = 0.011). Conclusions: The efficacy of low-dose atropine eye drops in pediatric myopia patients has decreased since the beginning of the COVID-19 pandemic.
