As prenatal ultrasonography becomes popular, the number of prenatal diagnosis of congenital surgical diseases is also increasing. To evaluate the impact of antenatal ultrasonography on outcome the mortality rate in neonatal surgical emergencies was studied. The authors retrospectively reviewed 281 patients (congenital diaphragmatic hernia: 44, tracheoesophageal fistula: 78, intestinal atresia: 98, omphalocele: 28 and gastroschisis: 33 who had been managed at Seoul National University Childrens Hospital, from January 1991 to December 2000. The patients were divided into two groups; group A (1991 to 1995; 139 patients) and group B (1996 to 2000; 142 patients). These two groups were subdivided into prenatally diagnosed subgroup and postnatally diagnosed subgroup. We analyzed the changes of prenatal diagnosis rate, total mortality rate, and mortality rate of subgroups. Prenatal diagnosis rate was increased significantly in group B (Group A: 24.5 % and Group B: 45.1 %). Total mortality rate of group A was 21.6 %, and that of group B was 10.6 %, showing a significant decrease in group B. However, in both group A and B, when compared antenatally diagnosed subgroup with postnatally diagnosed subgroup, the mortality rate was lower in postnatally diagnosed subgroups but statistically not significant. The authors conclude that although prenatal diagnosis rate has been increased, prenatal diagnosis itself has not resulted in significant improvement in outcome.

Purpose: To elucidate the sequential radiologic manifestations of reperfusion edema after lung transplantation. Materials and Methods: The study group comprised five consecutive lung transplant recipients (M:F=3:2; mean age; 47.5 years) who between July 1996 and April 2002 underwent lung transplantation procedures (four, unilateral; one, bilateral) at our institution. We retrospectively reviewed the serial postoperative radiographs obtained and characterized the lung infiltrates. Results: Lung infiltrates compatible with reperfusion edema were present in all patients (5/5). Reperfusion edema appeared on day 1 in four, and by day 2 in the other. In all transplanted lungs, infiltrates were found in the perihilar and basilar regions, and were scored as maximal on day 1 in one, day 3 in two, day 4 in one and day 5 in the other. Conclusion: The recognition of sequential radiological manifestations helps identify recognition of reperfusion edema after lung transplantation. 목적: 본 연구는 폐이식후 재관류부종의 시기에 따른 방사선적 소견을 기술하려고 한다. 대상과 방법: 본원에서 폐이식을 시행받은 5명의 수여자를 대상으로 하였다. 1996년 7월부터 2002년 3월까지 세 명의 남자와 두 명의 여자가 폐이식을 받았고, 평균 연령은 47.5세 였다. 이 중 4 명은 한쪽 폐만 이식을 받았고, 1명은 양폐 이식을 받았다. 모든 수술후 연속적인 수술후 방사선 사진을 분석하고, 폐음영을 기술 하였다. 결과: 재관류부종은 네 명에서는 수술후 1일째에 , 한 명에서는 2일째에 나타났다. 최대치의 폐음영은 한 명에서 수술후 1일에, 두 명에서 수술후 3일째에, 한 명에서 4일째에, 나머지 한 명은 술후 5일째에 있었다. 결론: 재관류부종은 모든 폐이식 이후에 일어나는 현상이며 방사선학적으로는 폐문주위와 하폐에 우세하게 분포하는 미세 망상형 또는 기강경화로 나타나며, 약 5일 이내에 최대 시기를 거치고 3주 이내에 특별한 치료없이 소실된다.

Currarino syndrome is a hereditary syndrome characterized by the triad of a sacral bony defect, presacral mass and anorectal malformation. We retrospectively reviewed 13 Currarino syndrome patients who were treated in our center between 1997 and 2010. Demographic data, initial symptoms, initial diagnosis. pathologic diagnosis of presacral mass, associated anomalies and managements were analyzed. There were 8 boys and 5 girls. Four patients were diagnosed as Currarino syndrome immediately after birth with failure of passage of meconium and abdominal distension. Four patients underwent surgery for imperforate anus immediately after birth and W8re diagnosed as Currarino syndrome later and underwent reoperation. Three patients were diagnosed during work-up and management with of the tentative diagnosis of Hirschsprung's disease. Diagnosis of the remaining two patients was at the age of 26 months and 9 years and anorectal malformation was not associated. Twelve patients showed hemi-sacrum and one patient showed bilateral sacral subtotal agenesis. Two patients without anorectal malformation underwent presacral mass excision, untethering of spinal cord and repair of myelomeningocele. Six out of 8 patients, excluding 3 that expired or were lost to follow up, with anorectal malformation underwent colostomy, presacral mass excision, untethering of spinal cord, repair of myelomeningocele, posterior sagittal anorectoplasty and colostomy repair. One patient underwent only posterior sagittal anorectoplasty after colostomy. One waits the scheduled operation only with Hegar dilatation. Pathologic examation of presacral masses showed myelomeningoceles in 4 patients, lipomyelomeningoceles in 3 patients and dermoid Cyst in one patient. Teratoma was combined in 2 patients. Eight patients needed neurosurgical operation for spinal cord problems. Seven patients had urologic anomalies and two of them underwent operation. Currarino syndrome should be considered as a differential diagnosis in pediatric patients with abdominal distension, constipation and anorectal malforlnation. For proper evaluation and treatment, a multi-disciplinary approach is recommended.

Extracorporeal membrane oxygenation (ECMO) has been utilized in congenital diaphragmatic hernia (CDH) patients with severe respiratory failure unresponsive to conventional medical treatment. We retrospectively reviewed 12 CDH patients who were treated using ECMO in our center between April 2008 and February 2011. The pre ECMO and on ECMO variables analyzed included gestational age, sex, birth weight, age at the time of ECMO cannulation, arterial blood gas analysis results, CDH location, timing of CDH repair operation, complications and survival. There were 9 boys and 3 girls. All patients were prenatally diagnosed. Mean gestational age was $38.8{\pm}1.7$ weeks and mean birth weight was $3031{\pm}499$ gram. Mean age at the time of ECMO cannulation was $29.9{\pm}28.9$ hours. There were 4 patients who survived. Survivors showed higher 5 min Apgar scores ($8.25{\pm}0.96$ vs. $7.00{\pm}1.20$, p=0.109), higher pre ECMO mean pH ($7.258 {\pm}0.830$ vs. $7.159{\pm}0.986$, p=0.073) and lower pre ECMO $PaCO_2$ ($48.2{\pm}7.9$ vs. $64.8{\pm}16.1$, p=0.109) without statistical significance. The hernia was located on the left side in 10 patients and the right side in 2 patients. The time interval from ECMO placement to operative repair was about 3~4 days in 5 early cases and around 24 in the remaining cases. There were 3 cases of post operative bleeding requiring re operation and 2 cases of abdominal compartment syndrome requiring abdominal fascia reopening. ECMO catheter reposition was required in 4 cases. Three cases of arterial or venous thrombosis were detected and improved with follow up. Our data suggests that ECMO therapy could save the lives of some neonates with CDH who can not be maintained on other treatment modalities. Protocolized management and accumulation of case experience might be valuable in improving outcomes for neonates with CDH treated with ECMO.

Hickman catheters are tunneled central venous catheters used for long-term venous access in children with malignancies. The appropriate management for various kinds of catheter related complications has become a major issue. We retrospectively analyzed the clinical, demographic, and surgical characteristics in 154 pediatric hemato-oncology patients who underwent Hickman catheter insertion between January 2005 and December 2009. There were 92 boys and 62 girls. The mean age at surgery was $7.6{\pm}5.1$ years old. The mean operation time was $67.4{\pm}21.3$ minutes and C-arm fluoroscopy was used in 47(30.5 %). The causes of Hickman catheter removal were termination of use in 82 (57.3 %), catheter related bloodstream infection in 44(30.8 %), mechanical malfunction in 11(7.7 %), and accidents in 6(4.2 %). Univariate and multivariate analysis for associated factors with catheter related bloodstream infection showed that there were no statistically significant associated factors with catheter related infection complications. All cases except two showed clinical improvement with catheter removal and relevant antibiotics treatment. The mean catheter maintenance period in patients of catheter removal without complications was $214.9{\pm}140.2$ days. And, The mean catheter maintenance period in patients of late catheter related bloodstream infection was $198.0{\pm}116.0$ days. These data suggest that it is important to remove Hickman catheter as soon as possible after the termination of use. When symptoms and signs of complications were noticed, prompt diagnostic approach and management can lead to clinical improvements.

Spatial planning, is required to be conceptualized corresponding to the shifts in planning paradigm through logical and systematic approaches. The concept of planning, thus, should be considered in terms of not only the planning discipline but also the planning activities or practices. This study aims to review and examine the concept of spatial planning based on the different approaches of planning and analyze the difference between land use planning, then review a meaning of spatial planning in terms of its dimensions. The research range will be limited to only the concept of spatial planning and survey was carried on through collecting the secondary research data by literature reviews and both descriptive and comparative approaches will be applied concurrently. The key findings of the study can be found as follows: Firstly, spatial planning has been reviewed with regard to theoretical, practical and integrated approaches. Secondly, the concept of spatial planning has been examined in terms of definitions, dimensions and analysis criteria and then analyzed conceptual differences compared with traditional land use planning. Finally, a meaning of spatial planning has been highlighted based on the dimensions of spatial planning, such as future visions, policy toolbox, sustainable development and inclusivity. 공간계획은 논리적 체계적 접근을 통하여 계획의 패러다임 변화에 상응하는 개념화가 요구되고 있으며, 또한 이러한 공간계획의 개념은 계획 이론과 실제를 고려한 접근이 필요하다. 따라서 본 연구의 목적은 공간계획에 대한 이론적 실제적 통합적 접근방법을 통하여 및 그 개념을 파악하고, 전통적인 개념인 토지이용계획과의 차이점을 분석하여 공간계획의 의의를 재조명하고자 하는 것이다. 이러한 연구목적을 달성하기 위하여 연구범위는 공간계획의 개념으로 한정하고, 조사방법은 문헌조사를 통하여 2차 자료를 수집하였으며, 접근방법은 서술적 접근방법과 비교론적 접근방법을 병용하였다. 연구결과는 다음과 같은 관점에서 도출하고자 하였다. 첫째, 공간계획에 대한 접근은 계획이론의 이론적 실제적 통합적 차원에서 접근하였다. 둘째, 공간계획의 개념은 공간계획의 정의, 차원, 그리고 평가의 측면에서 검토하고, 토지이용계획과의 개념적 차이를 비교 분석하였다. 마지막으로 공간계획의 의의는 미래상, 정책도구, 지속가능한 발전 그리고 개방성 차원에서 파악하고자 하였다.
