  • Background: We aimed to evaluate the efficacy and safety of early surgical ligation (within 15 days of age) over late surgical ligation (after 15 days of age) by a comparative analysis of very low birth weight (VLBW) infants undergoing surgical correction for symptomatic patent ductus arteriosus (PDA) over the course of 6 years in our hospital. Methods: We retrospectively reviewed all the medical records in the neonatal intensive care unit at Hanyang University Seoul Hospital, from March 2007 to May 2013, to identify VLBW infants (<1,500 g) who underwent surgical PDA ligation. Results: The gestational age (GA) in the late ligation (LL) group was significantly younger than in the early ligation (EL) group (p=0.010). The other baseline characteristics and preoperative conditions did not differ significantly between the two groups. The intubation period before surgery (p<0.001) and the age at surgery (p<0.001) were significantly different. The postoperative clinical outcomes of the study patients, including major morbidity and mortality, are summarized. There were no significant differences in bronchopulmonary dysplasia, sepsis, or mortality between the EL and the LL groups. However, the LL group was significantly associated with an increased risk of necrotizing enterocolitis (p=0.037) and with a prolonged duration of the total parenteral nutrition (p=0.046) after adjusting for GA. Conclusion: Early surgical ligation for the treatment of PDA that failed to close after medical treatment or in cases contraindicated for medical treatment might be desirable to reduce the incidence of necrotizing enterocolitis and to alleviate feeding intolerance in preterm infants.

  • 1.55${\mu}m$ InGaAsP/InGaAsP 다중양자우물주고 전계흡수형 광변조기에서 캐리어 수송현상과 입력광 세기가 소광특성에 미치는 영향을 조사하였다. 포와송 방정식과 전자 및 정공의 전류 연속방정식, 광분포들을 양자우물에서의 전게강도에 따른 흡수계수들을 고러하여 self-consistent하게 해석하였다. 이종접합계면에서의 캐리어의 축적 및 광도파로영역에서의 공간전하에 의한 전계차폐 현상은 입사광 파워가 증가할 수록 입사단 영역에서 심하게 나타남을 알 수 있었다. 캐리어의 전계차폐에 의한 소광비 저감은 변조기가 길이가 200${\mu}m$정도로 긴 경우에는 입사광 파워가 약 10mW이상에 대해서 심하게 나타날 수 있음을 알 수 있었다. 이러한 캐리어의 전계차폐에 따른 소광비 특성열화는 특히 입사광 파워가 클 수 있는 1..55${\mu}m$ DFB-LD와 전계흡수형 광변조기 집적소자나 광변조기 길이가 수십 ${\mu}m$로 짧은 초고속 광흡수변조기의 경우에 더욱 심하게 나타날 수 있음을 지적하였다.

  • It has been proposed that G protein interacts with receptor via multiple interaction sites. With regard to this, C-terminus of the G${\alpha}$ subunit is clearly not the only structural determinant on the G proteins that is critical for receptor coupling selectivity, but the extreme N-terminus of Ga subunit and other structural elements were proposed to be responsible for dictating the interaction with receptors.

  • In this paper, we study the effect of substrate temperature on property of Ga doped ZnO (GZO) thin film for transparent conductive oxide (TCO).GZO thin films have been deposited on corning glass 1737 by D.C. magnetron sputtering. We investigated the structural and electrical properties of GZO films using the X-Ray Diffractometer(XRD), Field Emission Scanning Electron Microscopy(FESEM) and 4-points probe .
