Inguinal hernia is the most common disease treated by the pediatric surgeon. There are several controversial aspects of management 1)the optimal timing of surgical repair, especially for preterm babies, 2)contralateral groin exploration during repair of a clinically unilateral hernia, 3)use of laparoscope in contralateral groin exploration, 4)timing of surgical repair of cord hydrocele, 5)perioperative pain control, 6)perioperative management of anemia. In this survey, we attempted to determine the approach of members of KAPS to these aspects of hernia treatment. A questionnaire by e-mail or FAX was sent to all members. The content of the questionnaire were adapted from the "American Academy of Pediatrics (AAP) Section on Surgery hernia survey revisited (J Pediatr Surg 40, 1009-1014, 2005)". For full-term male baby, most surgeons (85.7 %) perform an elective operation as soon as diagnosis was made. For reducible hernia found in ex-preterm infants already discharged from the neonatal intensive care unit (NICU), 76.2 % of surgeons performed an elective repair under general anesthesia (85.8 %). 42.9 % of the surgeons performed the repair just before discharge. For same-day surgery for the ex-premature baby, the opinion was evenly divided. For an inguinal hernia with a contralateral undescended testis in a preterm baby, 61.9 % of surgeons choose to 'wait and see' until 12 month of age. The most important consideration in deciding the timing of surgery of inguinal hernia in preterm baby was the existence of bronchopulmonary dysplasia (82.4 %), episode of apnea/bradycardia on home monitoring (70.6 %). Most surgeons do not explore the contralateral groin during unilateral hernia repair. Laparoscope has not been tried. Most surgeons do not give perioperative analgesics or blood transfusion.

잔존 총배설강 기형 수술 후 발생한 요도-질 누공에 대한 전방 시상 경직장적 접근 술식 (Anterior Sagittal Transrectal Approach, ASTRA) 1 례보고

The authors applied anterior sagittal transrectal apporach (ASTRA) for the repair of urethrovaginal fistula which developed after total repair of persistent cloaca. The patient had been diagnosed to have persistent cloaca, double uterus and double vagina, and received PSARP, excision of right-side uterus and vagina, and left vaginal switch operation at 22 months old. After operation, the patient admitted several times due to frequent urinary tract infection and ectopic stone formation in bladder and neovagina. Urethro-neovaginal fistula was confirmed by cystoscopy and corrected with ASTRA. Postoperative voiding cystourethrogram showed no fistula tract. ASTRA showed improved surgical field, minimized ureterocystic damage, and preserved perirectal nerve due to limited incision of rectum.

New azomethine metal complexes were synthesized systematically and characterized. Beryllium, magnesium, or zinc ions were used as a central metal cation and aromatic azomethines (L1-L4) were employed as a chelating anionic ligand. Emission peaks o f the complexes in both solution and solid states were observed mostly at the region of 400-500 nm in the luminescence spectra, where blue light was emitted. Three of them (BeL1 (Ⅰ), ZnL2 (Ⅱ), and ZnL3 (Ⅲ)) were sublimable and thus were applied to the organic light-emitting devices (OLED) as an emitting layer, respectively. The device including the emitting layer of Ⅰ exhibited white emission with the broad luminescence spectral range. The device with the emitting layer of Ⅱ showed blue luminescence with the maximum emission peak at 460 nm. Their ionization potentials, electron affinities, and electrochemical band gaps were investigated with cyclic voltammetry. The electrochemical gaps of 2.98 for I, 2.70 for Ⅱ, and 2.63 eV for Ⅲ were found to be consistent with their respective optical band gaps of 3.01, 2.95 and 2.61 eV within an experimental error. The structure of OLED manufactured in this study reveals that these complexes can work as electron transporting materials as well.

Superior mesenteric artery (SMA) syndrome is a rare disorder caused by extrinsic compression of the third portion of the duodenum by the SMA. The operative treatment of choice is bypassing the obstructed duodenal segment by duodenojejunostomy. We report one case of SMA syndrome treated by laparoscopic duodenojejunostomy and followed up by 3D-reconstructive CT scan. A fifteen-year-old boy with intermittent vomiting and weight loss was admitted. Ultrasonography showed narrowing of the distance between the SMA and aorta. Hypotonic duodenography showed dilatation of duodenal third portion and barium stasis. On 3Dreconstructive CT scan, the angle between SMA and aorta was $37^{\circ}$. The postoperative course was uneventful. Three months later, he had gained 3 kg of weight and the angle between SMA and aorta increased to $38-39^{\circ}$ on 3D reconstructive CT scan. Laparoscopic duodenojejunostomy for bypassing the obstructive duodenum in SMA syndrome is a feasible and safe method.

Fatigue tests and analyses were carried out to investigate fatigue strength and crack initiation point of load-carrying asymmetric double bevel cruciform welded joints. Mesh-insensitive structural stress approach was adopted to estimate high precise fatigue life and crack initiation point. Two different case material and weld shape were considered in this study. Results of fatigue tests and analyses were compared and discussed in consideration of applicability of structural stress approach as the reliable fatigue assessment method of cruciform welded joints.

지반위에 놓인 콘크리트 슬래브가 온도하중을 받을 때 지반의 전단저항과 슬래브 하부와 지반과의 마찰 등에 의해 생기는 슬래브 하부의 수평저항을 고려하여 지반위에 놓인 콘크리트 슬래브의 거동을 분석하였다. 지반위의 콘크리트 슬래브와 강성도로포장의 해석에 널리 사용되는 탄성지반위의 얇은 판을 이용하여 슬래브 하부의 수평저항을 고려하기 위한 해석 공식을 유도하였다. 이를 이용하여 판요소와 쉘요소를 이용한 유한요소법에 의한 모델을 개발하여 수치해석 결과를 도출하였다. 해석 공식과 수치해석 모델을 이용한 해석 결과를 비교 분석하였고 매우 비슷한 결과가 도출 되는 것을 알 수 있었다. 슬래브의 상부와 하부에 온도 차이가 있을 때와 슬래브의 온도가 전체적으로 감소할 때, 콘크리트 슬래브의 응력 분포에 슬래브 하부의 수평저항이 미치는 민감성을 여러 가지의 다른 슬래브의 두께, 탄성계수, 그리고 지반의 수직탄성계수 등을 고려하여 분석하였다. 해석 결과에서 온도하중을 받을 때 슬래브 하부의 수평저항은 슬래브의 응력에 매우 큰 영향을 미칠 수 있다는 것을 발견하였다.

소아 급성 충수염의 진단과 치료: 10년간의 변화

Appendicitis is the most common surgical emergency in childhood and the technologic advances of modern medicine have affected the diagnosis and treatment of appendicitis. This study is to evaluate the differences in diagnosis and treatment of appendicitis between present and 10 year ago. The authors retrospectively reviewed the medical records of patients who underwent appendectomy under the diagnosis of the acute appendicitis from July 1993 to June 1995 (Group A, n = 78) and from July 2003 to June 2005 (Group B, n = 105). There are no differences between group A and B in mean age ($8.5{\pm}3.6$ vs. $9.3{\pm}3.1$ year), duration of symptoms ($3.0{\pm}3.2$ vs. $2.6{\pm}3.8$ days), and postoperative hospital stay ($6.6{\pm}4.8$ vs. $5.8{\pm}3.6$ days). Preoperative abdominal ultrasonogram and/or computed tomogram was performed in 7 patients (9.0 %) of group A and in 51 patients (58.5 %) of group B. Thirty-six patients (34.3 %) of group B underwent laparoscopic appendectomy, but none in group A. Incidence of a histologically normal appendix decreased from 15.8 % in group A to 4.8 % in group B (p =0.018). This study suggests that utilization of abdominal ultrasonogram or computed tomogram in preoperative evaluation become more popular and surgical treatment of acute appendicitis become more minimally invasive. The rate of negative appendectomy was also reduced compared with 10 year ago.

Esophageal atresia without tracheoesophageal fistula accounts for 7-11 % of all types of esophageal atresia and is very difficult to treat. In our hospital from 1990 to 2005, we operated upon 40 patients with esophageal atresia, and 6 had pure atresia. The preoperative characteristics, operative findings and post operative course of the six patients with pure atresia were analysed. Immediate gastrostomy was performed in all 6 patients. One patient had simultaneous cervical esophagostomy. Esophageal reconstruction procedures were transhiatal gastric pull up in 3 patients, esophagocologastrostomy utilizing left colon in 1, and transthoracic esophagoseophagostomy with esophageal bougination in 2. Postoperative complications were pneumonia, anastomosis leakage, and gastroesophageal reflux symptom. Conservative management was effective in all patients. A larger series of cases would be required to demonstrate the most effective treatment for this particular anomalous condition.
