서울과 고산의 미세입자 수분함량에 영향을 미치는 주요 인자
최은경,김용표 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.6
Water contents in fine particles at Seoul and Gosan are estimated by using a gas/particle equilibrium model, SCAPE(Simulating Composition of Atmospheric Particles at Equilibrium) Also, sensitivity of particulate inorganic ionic concentrations on the total ionic species is estimated Water content at Gosan is more sensitive to ambient relative humidity (RH) than Seoul At both sites water content is most sensitive to sulfate concentration among sulfate, nitrate, and ammonium Solid salts levels and compositions are also studied
일본근대의 ‘화장(化粧)’이라는 젠더표상 -히구치 이치요(樋口一葉) 『탁한 강(にごりえ)』을 중심으로-
최은경 중앙대학교 일본연구소 2023 日本 硏究 Vol.- No.59
This study examines the gender representation of “make-up” in modern Japan through an analysis of Higuchi Ichiyo’s work, “Nigorie.” “Nigorie,” set in Meiji 28, follows a married woman, Ohatsu, who has traces of black teeth and shaved eyebrows., and the prostitute, Oriki, who represents status with her white powdered make-up up to the collar. The “make-up” signifies obedience in a wife and heightened femininity. It functions as a gender representation of enforced norms in the patriarchal social structure of the time. Both Ohatsi and Oriki are passive beings. One supports her husband inside and outside the home; the other becomes the object of male sexual desire. Ohatsu is unilaterally notified that her husband is divorcing her. Oriki meets a miserable end at the hands of Genshichi. Despite their differing status and positions, both women lose their livelihoods due to a man’s actions. Remarkably, Genshichi, the perpetrator, is praised for his “good death” through a traditional form of suicide known as “disembowelment.” This irony highlights the persistence of old traditions and values in modern society. “Nigorie” expresses archaic conventions and gender norms within the backdrop of a patriarchal modern society.
Review of the Registration in the Clinical Research Information Service
최은경,김미정,임남규,박현영 대한의학회 2016 Journal of Korean medical science Vol.31 No.1
Clinical research registration is required in many countries to improve transparency of clinical research and to ensure subject safety. Developed in February 2010, the Clinical Research Information Service (CRIS) is an online registration system for clinical studies in Korea and one of the primary registries of the World Health Organization (WHO) International Clinical Trials Registry Platform. The present analysis investigated the characteristics of studies registered in the CRIS between February 2010 and December 2014. Data for the analysis were extracted from the CRIS database. As of December 31, 2014, 1,323 clinical studies were registered. Of these, 938 (70.9%) were interventional studies and 385 (29.1%) were observational studies. A total of 248 (18.7%) studies were funded by government sources, 1,051 (79.4%) by non-government sources, and 24 (1.8%) by both. The most frequently studied disease category based on the ICD-10 classification was the digestive system (13.1%), followed by the nervous system (9.4%) and musculoskeletal system (9.1%). Only 17.8% of the studies were registered prior to enrollment of the first subject. Comparing the number of registered or approved clinical studies between the CRIS, the Ministry of Food and Drug Safety, and ClinicalTrials.gov suggests that a considerable number of clinical studies are not registered with the CRIS; therefore, we would suggest that such registration should be the mandatory legal requirement.

ObjectiveaaTo investigate how differences in oxygen saturation between non-REM (NREM) and REM sleep in patients according to the severity of sleep apnea. MethodsaaWe studied 396 male patients diagnosed with simple snoring or obstructive sleep apnea syndrome (OSAS) on nocturnal polysomnography. Patients were divided into groups by the OSAS severity. We compared the average oxygen saturation between REM and NREM sleep in each group. ResultsaaIn the simple snoring group, average oxygen saturation was significantly greater during REM than during NREM sleep. In the severe OSA group alone, average oxygen saturation was greater in NREM than in REM sleep. The difference of NREM-REM average oxygen saturation correlated significantly with AHI in the severe OSA group. ConclusionaaMore severe hypoxemia was seen in REM than NREM sleep in the severe OSAS group. The differential oxygen decrease between REM and NREM sleep is likely due to the differentially occurring sleep breathing events in each sleep stage according to the SDB severity. The more AHI increases in the severe OSAS patients, the more prominent the hypoxemia of REM sleep compared with NREM sleep is likely to appear. This suggests that the pressure of continuous positive airway pressure should be increased to control the hypoxemia of REM sleep in extremely severe OSAS.
p-형 Si(100) 기판 위에 성장시킨 Bi_(3.25)La_(0.75)Ti₃O_(12) (BLT) 박막의 전기적 특성
최은경,박문흠,김현주,하태곤,강민주,김상수 昌原大學校 基礎科學硏究所 2003 基礎科學硏究所論文集 Vol.15 No.-
Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

Since the publication of Invisible Man, Ralph Ellison's only novel, various interpretations, opposing sentiments and reactions have existed. The novel begins and ends in a small underground room. It is there that the unnamed narrator is arranging his memories, structuring hs experiences, and creating his life. However, Ellison's apocalypse is a pessimistic one: it ends in destruction which leads not to regeneration but to degeneration. The Invisible Man is left with his 1,369 light bulbs, but they are no substitute for the reality, and he knows it. When the novel ends, we realize that its overall cyclic structure is not an upward spiral, but a vicious circle.
