환경공해, 약물 남용 등으로 인해 선천적으로 신체적 이상을 갖고 태어나는 어린이들이 늘고 있어, 어린이 건강, 더 나아가 국민 건강 향상에 악영향을 미치고 있다. 그러나 이 선천성 기형도 조기에 발견만하면 충분히 치료가 가능하다고 이동환 순천향의대 소아과교수는 지난 11월 11일 건강관리협회에서 있었던 건강관리 Work-shop을 통해 발표했다. 본문은 그의 발표문을 게재한 것이다.

Renal colic, hematuria, dysuria and stone passage were developed in younger brother (4 year 6 month old boy). But the elder sister (6 year old girl)had no specific symptoms and signs. The identification of the disease was proved by cyanide nitroprusside test and amino acid analysis of urine. In our patients the chromatographic amino acid patterns of urine showed remarkably increased excretion of cystine, ornithine, lysine, and arginine. They are managed by adequate hydration with Shohl solution for rendering the urine more alkaline, and alpha-mercaptopropionylglycine (Thiola).
A New Intelligent Controller Design for Discrete-Time T–S Fuzzy Models
이동환,주영훈,박진배 한국지능시스템학회 2009 한국지능시스템학회 학술발표 논문집 Vol.19 No.1
In this paper, a new periodic control law is suggested for the stabilization of discrete time Takagi?Sugeno (T?S) fuzzy models. Originally, [6] proposed periodic control law, and we expand this concept. The sufficient condition for stabilization is represented in the form of linear matrix inequalities (LMIs). Example is given to illustrate the advantage of the proposed methods.

Purpose: Preoperative aspects and dimensions used for an anatomical (PADUA) classification is useful to predict perioperative complications and warm ischemia time. However, it remains uncertain whether PADUA classification can predict intraoperative conversion from partial nephrectomy (PN) to radical nephrectomy (RN). We evaluate whether PADUA classification parameters can predict conversion to RN during PN. Materials and Methods: We retrospectively assessed data of 593 patients who underwent open PN and robotic PN for renal tumors by a single surgeon at a single tertiary center between December 2003 and September 2017. Intraoperative conversion to RN was performed in 17 of 593 patients who initially underwent PN. We evaluated the factors influencing the surgical modalities including PN and radical conversion cases. Then, the factors significantly associated with conversion to RN were further analyzed. Results: There were no significant differences between the 2 groups in age, longitudinal location, exophytic rate, and rim or face locations of renal masses. Renal sinus involvement, urinary collecting system involvement, and renal mass size were variables that predicted radical conversion, using univariate analysis. Renal sinus involvement (odds ratio [OR], 9.075; p=0.049) and urinary collecting system involvement (OR, 3.944; p=0.029) were independent predictors of intraoperative radical conversion, using multivariate analysis. Conclusions: The PADUA classification is a useful tool to predict intraoperative conversion from PN to RN. Renal sinus involvement and urinary collecting system involvement are the best predictors of intraoperative conversion from PN to RN.
