Measuring of the Perceptibility and Acceptability in Various Color Quality Measures
김아리,김홍석,박승옥 한국광학회 2011 Current Optics and Photonics Vol.15 No.3
Perceptibility and acceptability are the most often used threshold units in the field of color science. The former refers to a just perceptible difference and the latter evokes a tolerable color difference. Such thresholds can be very significant to color quality control processes in the printing industry and should be defined in quality measure units. Optical density (OD) and color difference models are usually utilized as color quality measures and have been provided in a considerable number of commercial measuring devices such as spectrophotometers. However, their merits and traits are far less understood in the literature. The present study intends to evaluate performance of those color quality measures including the OD and widely known color difference models, e.g. ΔE*ab, ΔECMC(l:c) and ΔE*00. A set of psychophysical assessments were carried out in order to accumulate the perceptibility and acceptability thresholds data, and their central trend was compared with the color quality measure estimates.

해파 모형(HYPA)으로부터 산출된 장기 파랑 자료를 이용하여 동해 근해의 파랑 특성을 분석하였다. 또한 파랑작용(wave action)에 의하여 형성되는 토사이동율을 동해안 연안에 대하여 도표화하여 동해안 연안표사수지(littoral sediment budget) 작성의 토대를 마련하였다. Statistical analysis oflong-tenn wave data resulted from HYPA(HYbrid PArametric wave model) for the eastern coast of Korea was performed. Subsequently a simple approach for predicting the global annual and seasonal littoral drifts has been derived to estimate littoral sediment budget.
Epstein-Barr Virus Infection with Acute Acalculous Cholecystitis
김아리,양혜란,문진수,장주영,고재성 대한소아소화기영양학회 2014 Pediatric gastroenterology, hepatology & nutrition Vol.17 No.1
Acute acalculous cholecystitis (AAC) is an inflammation of the gallbladder in the absence of demonstrated stones. AAC is frequently associated with severe systemic inflammation. However, the exact etiology and pathogenesis of AAC still remain unclear. Acute infection with Epstein Barr virus (EBV) in childhood is usually aymptomatic, whereas it often presents as typical infectious mononucleosis symptoms such as fever, cervical lymphadenopathy, and hepatosplenomegaly. AAC may occur during the course of acute EBV infection, which is rarely encountered in the pediatric population. AAC complicating the course of a primary EBV infection is usually associated with a favorable outcome. Most of the patients recover without any surgical treatment. Therefore, the detection of EBV in AAC would be important for prediction of better prognosis. We describe the case of a 10-year-old child who presented with AAC during the course of primary EBV infection, the first in Korea, and review the relevant literature.
요한 하우저 아르브뤼 작품의 조형적 특성을 활용한 3D 디지털 패션 디자인

This study aims to use Art brut works—the artwork of the socially underprivileged and alienated—to influence social roles in fashion design, employing a formative expression method to promote social acceptance of diversity in the industry. The research method involved investigating Art brut’s concept and evolution in domestic and foreign literature and previous studies. The formative characteristics of the movement were derived by analyzing the works of Art brut artist Johann Hauser. One hundred and twenty images of Johann’s work were collected through online sources like the Gugging Museum’s website, Christian Berst Gallery’s website were developed as fashion design using the CLO 3D program. The formative characteristics of Johann’s works appeared to be transparent overlapping, divisional decorativeness emphasized simplicity, and vibrant chromaticity. Based on this analysis, the results of the 3D digital fashion designs were as follows. First, the characteristics of the atypical objects and figures in Johann’s works were applied to the design silhouette, revealing a uniquely beautiful form. Second, Johann used a method in which numerous line shapes overlap and fill the area. The point of connecting the work is expressed as a graphic pattern by decorating the lines of the hem and hem of the garment with piping or attaching overlapping straps on top of pants and dresses. Third, the combination of overlapping colors used in Johann’s work is a color block design of fashion, which utilizes the formative fun.
