Purpose : The morphogenic mechanism of tetralogy of Fallot is known to be an antero-superior deviation and hypertrophy of the subpulmonary infundibulum. We performed this study to measure the subpulmonary infundibulum in patients with tetralogy of Fallot and compare those with normal control. Methods : Echocardiographic data and medical reports of 12 patients, with classical tetralogy of Fallot who were diagnosed echocardiographically from Dec. 1996 to Jan. 1999 in Kyungpook National University Hospital, were retrospectively reviewed. A control group consisted of 11 children who underwent a complete echocardiographic examination for a heart murmur and were found to be structually normal. Measurements of the subpulmonary infundibulum were performed in systolic still frames with the subxiphoid short axis view. Results : Compared with the normal control children, the following indexed infundibular dimensions in patients with tetralogy of Fallot were significantly smaller : volume, length, cross-sectional area, diameters of pulmonary valve annulus, main, left and right pulmonary arteries, PA index and McGoon ratio. The following measurements were increased in tetralogy patients : the angle between infundibular septum and ventricular septum, and infundibular free wall thickness. Conclusion : We confirmed both antero-superior deviation of infundibular septum and infundibular hypoplasia as morphologic abnormalities in tetralogy of Fallot. We also revealed relatively equal contributions of shortening of infundibular length, and increased infundibular septal and free wall thickness to infundibular hypoplasia. (J Korean Pediatr Soc 2000;43:1187-1191) 목 적 : 팔로4징의 원인은 누두부중격의 전, 상방으로의 변위와 비후 때문인 것으로 최근 알려지게 되었다. 이에 팔로4징 환아들의 누두부 형태를 계측하여 이를 정상 소아의 계측치와 비교 분석하고자 연구를 시행하였다. 대 상 : 1996년 12월부터 1999년 1월까지 경북대학교병원에 내원하여 심초음파 검사상 전형적인 팔로4징으로 진단받은 환아 12명을 대상으로 이들의 심초음파 소견 및 병력지를 후향적으로 조사하였다. 정상 대조군은 심잡음이 들려 심초음파 검사를 받고 심장에 특별한 이상이 없고, 환자군과 연령이 비슷한 정상소아 11명을 선택하였다.Subxiphoid short axis view의 수축기 정지화면에서 폐동맥직하 누두부의 계측을 시행하였다. 결 과 : 팔로4징 환아들은 정상 대조군에 비하여 누두부 용적, 길이, 단면적, 폐동맥판륜직경, 주폐동맥직경, 좌, 우 폐동맥직경, PA index 및 McGoon률 등이 유의하게 작았다. 반면에 누두부중격-하부중격 각도 및 누두부 전벽의 두께는 유의하게 컸다.

Purpose : Perinatal asphyxia is an important cause of neonatal mortality and subsequent lifelong neurodevelopmental handicaps. Although many treatment strategies have been tested, there is currently no clinically effective treatment to prevent or reduce the harmful effects of hypoxia and ischemia in humans. In the clinical setting, maternal hyperthermia induces adverse effects on the neonatal brain, but recent studies have shown that hyperthermic pretreatment (PT) plays some role in hypoxic-ischemic (HI) injuries of the developing brain. The present study investigated the effect of hyperthermic PT on HI brain injuries in newborn rats. Methods : HI was produced in 7-day-old neonatal rats by unilateral common carotid artery ligation, followed by hypoxia with 8% oxygen at 38℃ for 2 hours. Twenty-four hours before HI, one-half of the pups were exposed to a 40℃ environment for 2 hours. The severity of the brain injury was assessed 7 days after the HI. Results : Hyperthermic PT reduced the gross and histopathologic findings of brain injury from 64.7 to 31.2% (P<0.05). There were no differences in location and severity of injury between the pretreated and control brains. Conclusion : These findings indicate that hyperthermic PT provides neuroprotective benefits on HI in the developing brain. Also, these findings suggest maternal hyperthermia may have protective effect on perinatal HI brain injuries.

This study attempted to examine the relationship among corporate governance, ownership structure and tax avoidance with Korean enterprises listed in the stock market on tax avoidance by the management from 2008 through 2012. Results showed that corporate governance had a significant positive (+) impact on tax avoidance. In addition, a higher proportion of largest shareholders and affiliated persons in an enterprise turned out to have a more significant negative (-) impact on tax avoidance. This is interpreted to mean the higher the proportion of largest shareholders and affiliated persons, the enterprise s tendency toward tax avoidance is less. When the detailed level of corporate governance on tax avoidance-based on ownership structure was examined, it was seen that the level of board of directors had solely a significant positive (+) impact on tax avoidance and a higher proportion of largest shareholders and affiliated persons in an enterprise had a more significant negative (-) impact on tax avoidance. Future researchers conducting studies on corporate governance, tax avoidance and ownership structure through empirical analysis may find useful insights from this study which has implications for corporate governance systems.
Review of Recent Aircraft Accidents in Relation to Aircraft Insurance
곽영암,홍수희 한국무역연구원 2015 무역연구 Vol.11 No.4
The first commercial flight in history occurred in 1914 at Florida, USA. Hence, commercial aviation has reached its 100th anniversary in 2014. However, the centennial anniversary of commercial flight was marked with big catastrophes involving Malaysian and Indonesian aircrafts. This paper analyzed some recent aircraft accidents and studied insurance goods for passenger in aircraft accidents. It also analyzed some recent cases of big casualties of aircraft accidents, international convention and treaty, Korean law system for air transit, insurance types and the risks it covered, and suitable and necessary insurance goods for passenger. For this reason, this paper focused on passenger accidents only, and excluded baggage and cargo.
자가면역성 간염과 담관병증의 중복증후군 (Autoimmune Overlap Syndrome) 1예

자가면역성 간질환은 우리나라를 포함한 동양권에서 드문 것으로 알려져 있으나 최근 성인에서의 보고가 증가하면서 소아에서도 증가되는 추세이다. 자가면역성 간질환에는 자가면역성 간염, 원발성 담즙성 간경변증, 자가면역성 담관병증, 원발성 경화성 담관염 등이 있다. 이들은 감별해야 하는 질환이면서 동시에 드물게는 중복되어 나타나는 경우가 있다. 저자들은 자가면역성 간염과 자가면역성 담관병증의 중복증후군을 문헌고찰과 함께 보고하는 바이다. 앞으로 사춘기 연령에서 급성 또는 전격성 간염의 감별진단 질환으로서 자가면역성 간질환 및 중복증후군을 염두에 둔다면 진단 및 치료에 도움이 되리라 생각한다.
