류영주,양희경,최정윤,김지수,황정민 대한신경과학회 2020 Journal of Clinical Neurology Vol.16 No.4

Background and Purpose The findings of ophthalmic examinations have not been systematically investigated in visual snow syndrome. This study reviewed the abnormal neuroophthalmologic findings in a patient cohort with symptoms of visual snow syndrome. Methods We retrospectively reviewed 28 patients who were referred for symptoms of visual snow to a tertiary referral hospital from November 2016 to October 2019. We defined the findings of best corrected visual acuity (BCVA), visual field testing, pupillary light reflex, contrast sensitivity, full-field and multifocal electroretinography, and optical coherence tomography. Results Twenty patients (71%) were finally diagnosed as visual snow syndrome. Their additional visual symptoms included illusionary palinopsia (61%), enhanced entoptic phenomenon (65%), disturbance of night vision (44%), and photophobia (65%). A history of migraine was identified in ten patients (50%). The mean BCVA was less than 0.1 logarithm of the minimum angle of resolution, and electrophysiology showed normal retinal function in all patients. Contrast sensitivity was decreased in two of the seven patients tested. Medical treatment was applied to five patients which all turned out to be ineffective. Among the eight patients who were excluded, one was diagnosed with rod-cone dystrophy and another with idiopathic intracranial hypertension. Conclusions Neuro-ophthalmologic findings are mostly normal in patients with visual snow syndrome. Retinal or neurological diseases must be excluded as possible causes of visual snow.

New Directions in Korean Literary Studies

류영주 고려대학교 민족문화연구원 2018 Cross-Currents Vol.0 No.27

This is a great time to be a scholar of modern Korean literature in North America. Over the last five years, a number of fine monographs have been published, including English-language studies by Hanscom (2013), Suh (2013), Hughes (2014), Poole (2014), Park (2015), Kwon (2015), and Lee (2015). Because of them, we now have an excellent understanding of the emergence of modern Korean literature during the first half of the twentieth century as an institution created within a charged force field shaped as intensely by nationalism as colonialism, by capitalism as socialism, and by tradition as revolution. More specifically, these studies have shed light on critical issues relevant to the domain of literary production, such as language ideologies and reform, practices and theories of translation, and material conditions of publishing and censorship, as well as questions of genre and medium. They have also helped us to situate the formation of modern Korean literature within global flows and comparative horizons, whether of the proletarian wave or global modernism. The two books under consideration in this essay expand on such scholarship by taking a more specialized approach, focusing on two bodies of texts that had previously received only fleeting attention: Russian literature in the case of Heekyoung Cho’s Translation’s Forgotten History: Russian Literature, Japanese Mediation, and the Formation of Modern Korean Literature, and Korean children’s literature in the case of Dafna Zur’s Figuring Korean Futures: Children’s Literature in Modern Korea. Whereas scholars have long appreciated the vital importance of each of these genres for understanding the formation of modern Korean literature, neither had yet merited a book-length study in English. Thus, in addition to providing valuable scholarship, these books may be viewed as exciting signs of the growth and maturation of the field....

Does Pregnancy after Renal Transplantation Affect Their Allograft and Pregnancy Outcomes?

류영주,최지윤,오정권 대한이식학회 2015 Korean Journal of Transplantation Vol.29 No.4

Background: The number of pregnancies in renal transplant recipients has increased. Many studies have shown that pregnancy increases the risk of graft, fetal, and maternal complications but does not affect the long-term outcome of the graft. We assessed the incidence and effect of pregnancy after renal transplantation and examined graft, fetal, and maternal outcomes. Methods: Our study included 145 female recipients of child-bearing age (15∼45 years) in our center from January 1990 to December 2011. The subjects were divided into two groups: pregnancy (n=17) and control (n=128). The 26 pregnancies in the 17 recipients were categorized as live births (n=10) or no-live births (n=16). These were analyzed for evaluation of pregnancy outcomes, graft function, and long-term graft survival. Results: The pregnancy and control group had similar graft function and graft survival rates 5- and 10-year after renal transplantation. Outcomes of pregnancy were 10 live births, 8 therapeutic abortions, 7 spontaneous abortions, and 1 stillbirth. The mean serum creatinine levels of the pregnant recipients diminished during the first trimester (1.14±0.37 mg/dL) and increased slightly during the third trimester (1.18±0.37 mg/dL) to levels nearer the baseline (1.23±0.37 mg/dL). These ranges were stable. The mean time from transplantation to pregnancy was 20.73±3.57 months. Live birth rates were associated with the time from transplantation to pregnancy (71.78±37.75 months for live births and 19.38±12.71 months for no-live births, P=0.000). There were no significant differences in graft function, graft failure rates, and survival. Conclusions: Pregnancy does not appear to have an adverse effect on graft function and the long-term outcomes of renal transplantation. Recipients with stable renal function who want to become pregnant can have successful pregnancies.

목적: 안과와 관련된 의료분쟁에서 피고의 특성, 법원의 판단결과와 손해배상금액 등을 분석하고자 하였다. 대상과 방법: 1989년부터 2014년까지 국내 안과 관련의료소송 중 판결이 종결된42건의 판례를 판례 검색 웹사이트를 통해 수집하였다. 결과: 최종 분석된 안과 관련 소송 결과는 원고 일부 승 26건, 기각 16건이었다. 피고 병원 유형은 의원 22건, 상급종합병원 16건,병원 6건이었다. 전체 소송의 판결금액은 총액 1,770,466,250원이었으며 평균 66,743,168원(5,000,000원-455,869,936원)이었다. 평균 청구 금액은 녹내장 분야가 223,788,608원으로 가장 많았다. 손해배상 청구의 62%가 설명의무위반으로 인한 정신적 손해에 대한 위자료 지급이었다. 의사가 배상한 경우는 망막 분야가 70% (7/10)로 가장 비율이 높았다. 1심 판결에 불복하여 2, 3심으로 진행된경우는 성형안과 분야가 가장 높았다(4/4). 의사가 배상한 판례 중 8건(62%)은 검사 및 진단행위 과실, 3건(23%)은 처치행위 과실,1건(9%)이 마취 및 회복과정의 과실로 판결되었다. 결론: 의원이 가장 많이 피소되었고, 62%에서 원고가 일부 승소하였다. 의사의 배상 이유로 설명의무 위반과 검사 및 진단행위 과실이가장 많아 이를 인지하는 것이 환자와 의사의 안전을 도모하고 의료 소송을 줄이는 데 도움이 되겠다. Purpose: To analyze the characteristics of defendants, court rulings and the compensation received in medical disputes relating to ophthalmology. Methods: Retrospective analyses of ophthalmic claims obtained from websites between 1989 and 2014 were performed. Results: Among 42 cases, 26 cases were ruled partially in favor of plaintiffs and 16 cases, ruled in favor of the defendant. Regarding the type of hospital, private clinics accounted for 22 claims, tertiary referral hospitals took 16 claims, and the secondary hospitals took 6 claims. The judgment amount of all of the lawsuits was ￦1,770,466,250 and average amount was ￦66,743,168 (￦5,000,000-￦455,869,936). The condition with the highest mean payment per claim was glaucoma (￦223,788,608). The consolation money for emotional distress due to violation of liability for explanation comprised a large proportion of the compensation, accounting for 62% of total payment. The conditions most likely to result in payment were those related to the retina, which occurred in 7 cases (70%). The conditions most likely to be appealed to a higher court were those involving oculoplasty (100%). Mismanagement of tests and misdiagnosis occurred in 8 cases (62%), mismanagement of treatment occurred in 3 cases (23%), and mismanagement of anesthesia and recovery occurred in 1 case (9%). Conclusions: Among all claims, those involving private clinics were most commonly involved (52%) and 62% of all claims were decided partially in favor of plaintiffs. Violation of liability during the explanation of the condition and negligence during the act of diagnosis and treatment were significant reasons for payment. Examination of these cases will help to promote patient safety and reduce repeated medical disputes.

중년에 시신경병증이 발현된 샤르코-마리-투스병 2A형 환자 증례 1예

류영주,유영석,김성준,Yung Ju Yoo,Young Suk Yu,Seong Joon Kim 대한안과학회 2014 대한안과학회지 Vol.55 No.4

Purpose: Charcot-Marie-Tooth disease type 2A (CMT2A) is caused by mutations in the mitofusin 2 (MFN2) genes associated with variable central nervous system (CNS) involvement. The authors report a case of a middle-aged woman with genetically confirmed CMT type 2 (CMT2), combined with delayed-onset bilateral optic neuropathy. Case summary: A 47-year-old woman presented with complaints of subacute decrease of visual acuity in both eyes. Her corrected visual acuity was 20/200 in the right eye and 20/320 in the left eye. Fundus photographs revealed bilateral disc pallor and diffuse retinal nerve fiber layer defects. No papillomacular bundle defect was observed. Goldmann perimetry showed central scotoma in both eyes. She had suffered from muscle wasting of the legs and foot deformities such as high arches and hammer toes since childhood and required a wheelchair for ambulation. A series of CMT gene mutation tests revealed an MFN2 gene mutation, c.617C>T (p.Thr206Ile), and the patient was diagnosed with CMT2A. Conclusions: Charcot-Marie-Tooth disease is a common inherited neuromuscular disorder and CMT2A, an axonal CMT neuropathy, is associated with bilateral optic neuropathy. Therefore, suspecting CMT and testing for gene mutations as part of the work-up in patients with subacute bilateral optic neuropathy associated with peripheral neuropathy is critical.

내재적∙친사회적 동기와 삶 만족도의 관계에서 그릿(Grit)과 친사회적 행동의 매개효과

류영주,양수진 한국심리학회 산하 한국발달심리학회 2017 한국심리학회지 발달 Vol.30 No.4

Currently, young adults in their twenties in Korea are experiencing the highest ever unemployment rate. This makes it hard for them to maintain social relationships, leading to lower life satisfaction. The current investigation explored the mediating effects of grit and prosocial behavior on the relationship between two types of motivation(intrinsic and prosocial motivation) and life satisfaction. A total of 356 adults in age range of 20-29 years participated in this study. While grit was a significant mediator regardless of motivation types, prosocial behavior was significant only for the relationship between prosocial motivation and life satisfaction. In the analyses of serial multiple mediation of grit and prosocial behavior, an indirect effect was observed. Grit underpinned the connection between motivation and behavior, which led to satisfaction. Across different developmental stages, intrinsic, prosocial motivation and prosocial behavior were suggested as unique variables that should be considered in improving young adults’ life satisfaction. Moreover, grit enhances life satisfaction by increasing prosocial behavior among people in their twenties, regardless of motivation type. 본 연구는 내재적·친사회적 동기가 삶 만족도를 예측하는지 확인하고, 그릿과 친사회적 행동의 매개효과가 나타나는지 구조방정식을 이용하여 검증해보고자 하였다. 20대 성인초기 남녀 443명을 대상으로 설문연구를 진행하였고, 그 중 연구 대상에 적합하고 성실하게 응답한 356명(남 153명, 여 203명)의 자료를 사용하였다. 검증 결과, 그릿은 내재적․친사회적 동기와 삶 만족도를 단순매개하였고, 친사회적 행동은 친사회적 동기와 삶 만족도의 관계만을 유의하게 매개하였다. 그릿과 친사회적 행동의 이중매개효과는 두 동기 유형에서 모두 유의하게 나타나 동기와 행동을 이어주는 그릿의 효과를 확인할 수 있었다. 본 연구의 결과는 20대의 삶에 대한 만족도와 관련하여 개인 내적 동기와 친사회적 행동을 고려해야 할 필요성을 시사하며, 그릿을 통해 개인이 가진 동기 유형에 상관없이 친사회적 행동을 증진시킬 수 있음을 보여준다. 이러한 결과를 바탕으로 발달적 관점에서 20대의 삶 만족도를 증진시키기 위해 고려해야 할 점과, 주관적 안녕감을 예측하는 새로운 변인으로서 그릿의 중요성에 대해 논의하였다.
