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.

선박엔진에서 발생하는 NOx 및 SOx 제거용 스크러버 폐세정액에 포함되어 있는 저농도상의 질산 및 황산이온을 비료상 물질로 회수하고자 하였다. 본 연구에서는 네 가지 유기용매를 적용하여 선택적으로 추출하여 회수하는 방법을 시험하였다. 아세톤과 메틸알콜을 이용하여 추출한 질산암모늄과 디에틸에테르와 에틸알콜을 적용한 황산암모늄의 시료를 적외석흡수분광법(IR)을 이용하여 분석한 결과, 상용제품과 거의 동일한 구성성분으로 나타났다. 이때 폐수로부터의 회수율은 최대 89%와 80%까지 각각 얻을 수 있었다. 따라서 배기가스 스크러버에 잔존해있는 질산이온과 황산이온에 대한 회수는 사용하는 용매의 선택도 및 용해도가 핵심적인 요소인 것으로 판단된다. Recovery of low level nitric acid and sulfuric acid ions, which were contained in wastewater of a wet scrubber for de-NOx and de-SOx from ship engines, was attempted as fertilizing materials. This study utilized a selective extraction method using four organic solvents to precipitate the solid salts of ammonium nitrate and ammonium sulfate. The IR analysis showed almost same composition of the extracted ammonium salts with a commercial product, and recovery rate of nitrogen and sulfuric ions was 89% and 80% respectively. It was found that the selectivity and solubility consequently could be the crucial factors to recover the low level ions from the waste scrubbing water.

Most patients with syndrome of obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) were presented with dysmenorrhea, pelvic mass and hematocolpos. These common symptoms of OHVIRA syndrome were aggravated soon after the menarche. Early diagnosis is important to relieve the symptom, to prevent injury of genital tract and to preserve fertility. We have experienced an unusual presentation of OHVIRA syndrome, which were presented with vaginal spotting and diagnosed at age 24. Therefore, we present it with a review of the literature.

본 연구에서 개발할 설계기술은 부가가치가 매우 높은 소량 다품종 건축용 내·외장재의 금속 패널 코너가공법에 관한 것이다. 금속 금구류 및 건축용 내·외장재로 사용되는 2.5mm이상 되는 금속강판을 사용함에 있어서 가장 문제가 되는 직각코너링 접합부위에서 발생되는 내식성(수명성), 내후성, 및 미 려성(디자인)을 향상시키므로 품질의 향상뿐만 아니라 소량 다품종의 생산성을 증대시킬 수 있는 국내 최초 금속패널 코너가공을 할 수 있는 벤딩다이시스템(Bending Die System)를 설계, 제작하여 경제적, 기술적으로 고부가가치를 창출하여 수출증대에 기여할 수 있다.
