Purpose: With increasing use of extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) in children, development of standardized strategies for survival prediction has become crucial; however, this has not been accom plished yet. We evaluated the adult scoring systems for survival prediction used for their applicability in pediatric ARDS and vali dated them. Methods: A total of 11 children with ARDS receiving ECMO from 2013 to 2014 were evaluated with adult scoring systems, including the Respiratory Extracorporeal-membrane-oxygenation Survival Prediction (RESP), the PRedicting dEath for SEvere ARDS on VV-ECMO (PRESERVE), and the ECMOnet scores. We compared the scores on these scales and the clinical characteristics between survi vors and nonsurvivors. Results: Eight of the 11 children died (72.7%). The PRESERVE score (survivors vs. nonsurvivors: 2 vs 5.25, P=0.048), and the ECMOnet score (4.1 vs. 5.63, P=0.048) were lower in survivors than in nonsurvivors. They correctly predicted mortality prediction. There was no significant difference in the RESP score between survivors and non-survivors (-4.33 vs -2.62, P=0.63). The parameters that showed significant differences in this study were peak inspiratory pressure, platelet, and delta neutrophil index. All children who were under immunocompromised conditions, such as those with tumors, or underwent hematopoietic stem cell transplantation died. The immunocompromised status should be considered an important factor for survival prediction in children with ARDS. Conclusion: This is the first pilot study to apply the survival prediction scoring system to pediatric ARDS with ECMO. It is necessary to establish and modify the survival prediction score system for pediatric ARDS with ECMO. (Allergy Asthma Respir Dis 2017:5:141-146)

산화그래핀 소재를 합성하여 투명한 박막 코팅기술을 개발하고 특성을 평가하였다. 스핀과 스프레이 공정을 동시에 이용하여 산화그래핀을 유리 기판에 균일하게 박막코팅을 하였다. 균일하게 산화그래핀을 스핀-스프레이 공정을 이용하여 박막코팅을 하기 위하여 유리기판을 amine-functional group으로 표면개질을 하였다. 또한, 스핀-스프레이 공정을 이용하여 산화그래핀 박막을 4층까지 적층을 하였고 86% 이상의 투명도를 확보하였다. 이와 같은 합성된 산화그래핀 박막소재의 스핀-스프레이 코팅 기술은 다양한 전자제품들의 display를 대면적으로 코팅할 수 있을 것으로 기대되어진다. In this study, we synthesized graphene oxide and developed novel spin-spray coating technology. The graphene oxide thin film was uniformly coated on amine-functionalized glass surfaces using spin-spray coating technology. We also stacked up to four layers of graphene oxide on glass substrates in a uniform manner. From the results, we infer that this spin-spray coating of graphene oxide thin film could be a powerful tool for various electronic display coating applications.
