Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The alone classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

Embolotherapy of Ruptured Gastroepiploico-Colic Communicating Artery with Median Arcuate Ligament Syndrome: A Case Report

이유현,김정원,박재형 대한영상의학회 2019 대한영상의학회지 Vol.80 No.5

Aneurysm of collateral vessels in celiac axis stenosis has seldom been reported. We report a case of hemoperitoneum due to spontaneous aneurysmal rupture of a previously unreported collateral vessel in a patient with median arcuate ligament syndrome. A 37-year-old man without any history of illness or trauma exhibited hemoperitoneum with an aneurysm in the right subhepatic area on CT. CT findings also included celiac stenosis due to median arcuate ligament thickening. Celiac and superior mesenteric artery angiography revealed an abnormal communicating artery aneurysm between the right gastroepiploic and right colic arteries. We named this aberrant anastomosis “gastroepiploico-colic communicating artery.” This rare collateral channel may cause spontaneous aneurysmal rupture in the presence of celiac stenosis. We successfully treated the aneurysmal rupture by transcatheter arterial embolization.

Characteristics of Ocular Manifestations of Patients with Coronavirus Disease 2019 in Daegu Province, Korea

이유현,김유철,신재필 대한의학회 2020 Journal of Korean medical science Vol.35 No.35

Background: The coronavirus disease 2019 (COVID-19) has reportedly affected almost 23 million people, with more than 800 thousand deaths globally. There have been a few reports on the ocular manifestations of COVID-19 patients in China but no reports in Korea. The present study aimed to examine ocular manifestations of COVID-19 patients in Korea. Methods: COVID-19 patients admitted from March 2020 to April 2020 at Keimyung University Dongsan Hospital and Keimyung University Daegu Dongsan Hospital were reviewed retrospectively for ocular manifestations. During the period of hospitalization, ocular symptoms as well as blood test results were noted and analyzed. Patients were then divided into the first-episode and relapsed group and ocular symptoms were analyzed in the groups. Results: A total of 103 patients were included in this study. Among them, 71patients were in the first-episode group and 32 patients in the relapsed group. No significant differences were determined in terms of positivity of ocular symptoms between the first-episode group (12 patients, 16.9%) and the relapsed group (10 patients, 31.3%, P > 0.05). Symptoms of positive upper respiratory infection and lower creatine phosphokinase were determined to be related to positive ocular symptoms. Conjunctival congestion was noted in seven patients. In the subgroup analysis, the conjunctival congestion-positive patients exhibited higher positivity of upper respiratory infection symptoms (100%) as compared with those in the negative group (40%, P = 0.017). Conclusion: Positive upper respiratory infection symptoms and lower creatine phosphokinase were determined to be related to ocular symptoms in COVID-19 patients. Among these patients, positive upper respiratory infection symptoms were associated with conjunctival congestion.

A Complex Cortical Malformation Caused by a Mutation in the Tubulin-Encoding TUBB3 Gene

이유현,박노혁 대한영상의학회 2020 대한영상의학회지 Vol.81 No.5

Tubulinopathy commonly refers to complex congenital and non-progressive brain malformations caused by mutations in the tubulin genes. Among tubulin-encoding genes, TUBB3 has rarely been reported as a cause of complex cortical malformations. Herein, we report a case of tubulinopathy in a 21-month-old boy who presented with delayed development. He could not walk on his own and was not able to speak more than five words. Physical examination revealed right esotropia and hypotonia of the lower extremities. MRI showed dysmorphic brainstem and dysmorphic and hypertrophic basal ganglia. The right thalamus was relatively smaller than the left one. The cerebellum showed disorganization of the cerebellar folia. DNA sequencing revealed a missense mutation of the TUBB3 gene.

Ocular manifestations in a patient with de novo Fabry disease

이유현,심규영,박성배,김유철 영남대학교 의과대학 2018 Yeungnam University Journal of Medicine Vol.35 No.2

Fabry disease (FD) is an X-linked, recessively inherited, rare, progressive, disorder of glycosphingolipid metabolism affecting multiple organs resulting in organ dysfunction. It is rare to find only one FD affected subject with a de novo mutation. Here we report a case of a 41-year-old Asian male diagnosed with de novo FD. Comprehensive ophthalmological evaluation was performed using slit lamp, color fundus photography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography. On slit lamp examination, cornea verticillata and slightly tortuous, and aneurysmal dilatation of inferior bulbar conjunctival vessels were observed. Other imaging modalities showed unremarkable findings. Cornea verticillata and inferior bulbar conjunctival vascular abnormalities may be detected earlier than other ocular abnormalities in de novo FDs like hereditary FDs.

Giant Intramyocardial Aneurysm in a Patient with Intercoronary Communication between the Left Circumflex Artery and Right Coronary Artery: A Case Report

이유현,박노혁,박지연,김선정 대한영상의학회 2020 대한영상의학회지 Vol.81 No.1

Coronary artery aneurysm is a rare disease. It occurs in the epicardial space, mostly along the course of major coronary arteries. Here, we report a case of a giant incidental aneurysm embedded in the basal posterior wall of the left ventricle. A 43-year-old woman was referred to our institution for the evaluation of cardiac palpitations that had been present from the previous 2 months. She reported no medical history (such as Kawasaki’s disease or hypertension) or previous operative history. Echocardiogram and subsequent cardiac CT revealed a giant aneurysm in the left ventricle, with a direct fistulous connection to a dilated and tortuous left circumflex artery, which showed direct communication with the straight right coronary artery.

Dilemma of Data Driven Technology Regulation : Applying Principal-agent Model on Tracking and Profiling Cases in Korea

이유현,정일영 한국디지털정책학회 2020 디지털융복합연구 Vol.18 No.6

This study analyzes the regulatory issues of stakeholders, the firm, the government, and the individual, in the data industry using the principal-agent theory. While the importance of data driven economy is increasing rapidly, policy regulations and restrictions to use data impede the growth of data industry. We applied descriptive case analysis methodology using principal-agent theory. From our analysis, we found several meaningful results. First, key policy actors in data industry are data firms and the government among stakeholders. Second, two major concerns are that firms frequently invade personal privacy and the global companies obtain monopolistic power in data industry. This paper finally suggests policy and strategy in response to regulatory issues. The government should activate the domestic agent system for the supervision of global companies and increase data protection. Companies need to address discriminatory regulatory environments and expand legal data usage standards. Finally, individuals must embody an active behavior of consent.

골격성 Ⅲ급 부정교합 환자 자매의 치험례 : A Case Report On Sisters

이유현 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.3

골격성Ⅲ급 부정교합으로 진단된 자매들로서 이상적인 치료 계획은 둘 다 악교정 수술을 동반한 교정치료였으나 언니의 경우만 술전 교정 후 양측성 하악지 시상 분할 골절단술로 치료하고 동생이 경우는 상악 제2소구치와 하악 제1소구치 발치를 통한 절충 치료를 시행하였다. 이에 본 증례 보고에서는 악교정 수술을 한 경우와 절충 치료를 한 경우를 비교하여 고찰해 보았다. Patients with skeletal classⅢ can be successfully treated by either orthognathic surgery or orthodontic treatment owing to unavoidable circumstances. Sisters were treated, elder sister by orthognathic surgery and younger one by compromised treatment. For the idal treatment goal, orthognathic surgery will be inevitable in skeletal problem case, but by the patient's private situations orthodontist cannot help doing compromised treatment. It could be another option if correct biomechanical approach is used.
