Propionic Acidemia with Novel Mutation Presenting as Recurrent Pancreatitis in a Child

최재영,장경미,민소윤,황수경,강빈,최병호 대한의학회 2019 Journal of Korean medical science Vol.34 No.47

Propionic acidemia (PA) is a rare organic acidemia resulting from a deficiency of the mitochondrial enzyme propionyl-coenzyme A carboxylase. Most cases are diagnosed after the detection of metabolic abnormalities—such as hyperammonemia, metabolic acidosis, and ketosis—associated with complaints of vomiting, feeding difficulties, and hypotonia during the neonatal period. However, in rare late-onset cases, mild or vague symptoms make the diagnosis more challenging. Even though acute pancreatitis is relatively uncommon in children, it can occur in association with PA. We present the case of a 4-year-old child who was admitted owing to the complaint of recurrent pancreatitis and had not previously been diagnosed with having metabolic disease. During inpatient treatment for acute pancreatitis, convulsions occurred with concomitant hyperammonemia, metabolic acidosis, coagulopathy, and shock 1 week after the administration of total parenteral nutrition. He was diagnosed to have PA after a metabolic work-up and confirmed to have novel mutation by molecular genetic analysis. Because children with PA may have acute pancreatitis, although rare, vomiting and abdominal pain should raise a suspicion of acute pancreatitis. On the contrary, even among children who have never been diagnosed with a metabolic disease, if a child has recurrent pancreatitis, metabolic pancreatitis caused by organic acidemia should be considered.

Does hospitals’ provision of uncompensated care deteriorate their profitability?: A longitudinal study of US hospitals

최재영,문성훈 한국회계학회 2014 회계저널 Vol.23 No.3

The purpose of the present study is to investigate the effect of uncompensated care (i.e., bad debt expenses and charity care) on the short-term, general non-profit hospital profitability measured by operating margin. We used hospital financial-year-end reports from the Washington State Department of Health for the 2006 to 2009 time period. We model the effects of bad debt expense and charity care, controlling for many observed time-varying factors such as average length of stay, bed occupancy rate, staff efficiency, Medicare and Medicaid dependency, teaching intensity, proportion of outpatient volume, and hospital fixed effect, which controls for hospital specific time-constant measures. Fixed effect models found the opposite directions of the coefficient estimates of the bad debt expenses between the private hospitals and public hospitals. Specifically, we found 1) a significant negative effect on operating margin among private non- profit hospitals and 2) a significant positive effect on operating margin among public hospitals, even after controlling for many observed time-varying covariates and hospitalfixed effect. There was no evidence that charity care provision had a significant effect on hospital profitability. Hospital executives and policymakers should keep track of profitability among community hospitals that provide large share of charity care and bad debts.

복합고분자용액법에 의한 가시광에 반응하는 TiO₂:Zr, N 광촉매의 제조 및 NO 광분해 특성

최재영,김지영,조영혁,장희동,장한권,김병곤,김태오,Choi, Jae-Young,Kim, Ji-Young,Cho, Young-Hyuek,Jang, Hee-Dong,Chang, Han-Kwon,Kim, Byoung-Gon,Kim, Tae-Oh 한국분말야금학회 2008 한국분말재료학회지 (KPMI) Vol.15 No.1

Visible-light responsive $TiO_2$:Zr, N powders were prepared by polymer complex solution method and the particle properties were characterized by using transmission electron microscope, BET method, X-ray diffractometer and UV-Vis spectrophotometer. The photocatalytic reactivity of the catalysts was also estimated by analyzing NO degradation. Polyhedral $TiO_2$ powder having about 20 um in the average particle diameter was successfully prepared, The XRD analysis revealed that the as-prepared powder consisted of anatase and rutile phases. The light absorption of the as-prepared $TiO_2$:Zr, N powder was shifted to the visible light. In addition, the as-prepared $TiO_2$:Zr, N nanoparticles showed the higher photocatalytic activity than the commercial $TiO_2$ under both UV and visible lights.

12% 크롬 로우터 강에서 응고속도와 가공조건이 미세 조직에 미치는 영향

최재영,강석봉,이래성 대한금속재료학회(대한금속학회) 1989 대한금속·재료학회지 Vol.27 No.1

The influence of solidification rates on the morphology and distribution of δ-ferrite and eutectic niobium carbides was studied using Bridgman-type unidirectional solidification apparatus in order to simulate the solidification pattern of a large-scale ingot of 12% chromium rotor steel. The volume fractions of the δ ferrite contained in the specimens solidified with the withdrawal speeds of 225 ㎜/hr, 45 ㎜/hr, and 4.5 ㎜/hr were measured to be 7%, 5%, and 30% respectively. δ-ferrite was finely distributed in the case of the withdrawal speeds of 225 ㎜/hr and 45 ㎜/hr, but the distribution was coarse network type in the case of the withdrawal speed of 4.5 ㎜/hr. When hot compressive working was applied in temperatures from 950℃ to 1250℃, 3-ferrite was transformed into carbides and austenite at the interface of δ-ferrite with the matrix. Subsequent heat treat melts result in a complete annihilation of δ-ferrite in the case of fast withdrawal speeds, but result in only a partial annihilation in the ca -e of the slow withdrawal speed, 4.5 ㎜/hr.

A Generalized Multiple Classifier System for Improving Computer-aided Classification of Breast Masses in Mammography

최재영 대한의용생체공학회 2015 Biomedical Engineering Letters (BMEL) Vol.5 No.4

Purpose The objective of this paper is to present a generalizedmultiple classifier system for improved classification ofmammographic masses in Computer-aided detection (CAD). Methods To encourage different base (component) classifiersto learn different parts of an object instant space, we developa novel base classifier generation algorithm which combinesdata resampling underpinning AdaBoost with the use ofdifferent feature representations. In addition, our proposedmultiple classifier system can be generalized beyond thelimitation of weak classifiers in conventional AdaBoostlearning. To this end, our multiple classifier system has aneffective and efficient mechanism for tuning the level ofweakness of base classifiers. Results Extensive experiments have been performed usingbenchmark mammogram data set to test the proposed methodon classification between mammographic masses and normaltissues. In addition, to assess classification performance, weused the area under the receiver operating characteristic(AUC) and the normalized partial area under the curve(pAUC). Results show that our method considerably outperforms(in terms of both AUC and pAUC) the most commonly usedsingle neural network (NN) and support vector machine(SVM) based classification approaches. In particular, theeffectiveness of our method in terms of correct classificationis much more significant over difficult mammogram cases withdense tissues that have higher risk of cancer incidences andcause higher false-positive (FP) detections. Conclusions Our multiple classifier system shows quitepromising results in terms of improving classificationperformances on the FP reduction application using classificationbetween masses

崔宰榮 한국중국언어학회 2001 중국언어연구 Vol.13 No.-

近代中國語시기에는 "被"被動文 이외에도 "吃"被動文, "敎"被動文, "給"被動文, "叫"被動文, "讓"被動文 등의 被動文이 출현하였다. 이들 被動文들을 기존의 被動文 즉 "爲"被動文, "見"被動文, "被"被動文과 비교해보면 그 來源에 있어서 현격한 차이를 나타낸다. "吃"와 같은 遭受義動詞에서 虛化된 것이 있는가 하면 "敎", "叫", "讓"등과 같이 使役動詞에서 虛化된 것이 있고, "給"과 같이 給予動詞에서 虛化된 것도 있다. 본고에서는 이들 중 唐宋時期에 출현한 "吃"被動文과 "敎"被動文에 대해서 唐宋時期의 口語體적 색채가 강한 다음과 같은 9종의 텍스트-《敦煌變文集》、《朝野僉載》、《入唐求法巡禮行記》、《祖堂集》、《全唐詩》、《王梵志詩》、宋人話本、《三朝北盟會編》、《朱子語類》-에 출현하는 例文들을 기반으로 하여 諸般關聯 問題들을 考察해보았다. 본고에서 다룬 主要內容으로는 다음과 같은 것들이 있다. 被動標志詞"吃"의 來源問題에 대한 토론, 唐宋時期"吃"被動文의 모습, "遭", "受", "遇"등이 被動標志詞로 변화할 수 있는가에 대한 가능성 검토, 使役動詞"敎"가 被動標志詞로 변환되는 메커니즘에 대한 고찰, 唐宋時期"敎"被動文의 모습, "與", "著"에 관한 필자의 견해 등등.

전략적 성과측정 지표 개발을 위한 사례 연구

최재영,최기준,권태형 한국경영과학회 2000 한국경영과학회 학술대회논문집 Vol.- No.2

The paper presents a case study with application of a performance measurement questionnaire in analyzing a semi-conductor-related manufacturing company. The case may contribute to the development of strategic performance measurement system. The questionnaire contains considerable non-financial measurement indices as well as financial ones, which may strengthen the strategic aspect of measurement system. The strategy, actions, and measures have to be balanced through communication process in an organization. The result shows the usefulness of the congruence and consensus analysis of performance factors in effectively managing strategic action programs and identifying investment task areas to be targeted.
