Mentoring is defined as a sustained relationship between a mentor and a mentee. Through continued involvement, the mentor offers support, guidance, and assistance as the mentee faces new challenges, or works to correct earlier problems. A mentoring for cooperative learning has many merits including higher order thinking, collaborative competencies, socialization and development. In this paper, a U(Ubiquitous)-CoMM(Community of mentor & mentee) system was supposed to design an instructional learning strategy using cyber community of mentor & mentee in a ubiquitous environment. The proposed system provides participants with campus mentoring program in which they share their experience and expertise. By experimental result showed that the proposed system is effect in education about cooperative learning than existing system. 멘토링은 멘토와 멘티의 지속된 관계로 정의된다. 지속적인 관여를 통해서 멘토는 멘티가 새로운 도전에 직면 또는 초기 문제들을 바로잡는데 있어서 안내와 보조, 지원을 제공한다. 협동학습을 위한 멘토링은 고급 사고력, 협력적 능력, 사회성 발달을 포함하여 많은 장점을 가진다. 본 논문에서는 유비쿼터스 환경에서의 멘토와 멘티의 사이버 커뮤니티를 이용한 교수학습 전략을 설계하기 위해서 U-CoMM 시스템을 제안하였다. 제안 시스템은 참여자에게 경험과 전문지식을 공유할 수 있는 캠퍼스 멘토링 프로그램을 제공한다. 실험결과 제안 시스템은 기존 시스템보다 협동학습에 있어 교육적 효과가 있음을 보여주었다.

Background: Extracorporeal membrane oxygenation (ECMO) has become increasingly accepted as a life-saving procedure for patients with severe acute respiratory distress syn- drome (ARDS). This study investigated the relationship between cumulative fluid balance (CFB) and outcomes in adult ARDS patients treated with ECMO. Methods: We retrospectively analyzed the data of adult ARDS patients who received ECMO between December 2009 and December 2019 at Korea University Anam Hospital. CFB was calculated during the first 7 days after ECMO initiation. The primary endpoint was 28-day mortality. Results: The 74 patients were divided into survivor (n=33) and non-survivor (n=41) groups based on 28-day survival. Non-survivors showed a significantly higher CFB at 1–7 days (p<0.05). Cox multivariable proportional hazard regression revealed a relationship be- tween CFB on day 3 and 28-day mortality (hazard ratio, 3.366; 95% confidence interval, 1.528–7.417; p=0.003). Conclusion: In adult ARDS patients treated with ECMO, a higher positive CFB on day 3 was associated with increased 28-day mortality. Based on our findings, we suggest a re- strictive fluid strategy in ARDS patients treated with ECMO. CFB may be a useful predictor of survival in ARDS patients treated with ECMO.

Hemitruncus arteriosus is a rare cardiovascular malformation in which one of the pulmo- nary arteries anomalously originates from the aorta. Left hemitruncus arteriosus, defined as the origination of the left pulmonary artery from the aorta, is less common than right hemitruncus arteriosus. In this study, we report the case of a neonate diagnosed with left hemitruncus arteriosus, ventricular septal defect, and atrial septal defect who underwent successful surgical treatment.
