      • 선천성 식도 무공증 및 기관식도 누공 - 대한 소아외과학회 회원을 대상으로 한 전국 조사 -

        박우현,권수인,김성철,김신곤,김우기,김인구,김재억,김현학,박귀원,박영식,송영택,양정우,오수명,유수영,이두선,이명덕,이성철,이석구,이태석,장수일,Park, W.H.,Kwon, S.I.,Kim, S.C.,Kim, S.K.,Kim, W.K.,Kim, I.K.,Kim, J.E.,Kim, H.H.,Park, K.W.,Park, Y.S.,Song, Y.T.,Yang, 대한소아외과학회 1995 소아외과 Vol.1 No.2

        국내에서 처음으로 기관식도기형에 관하여 대한소아외과 학회 회원을 대상으로 조사하였다. 본 연구는 두 부분으로 구성되어 있었는데 하나는 최근 3년간 출생한 기관식도기형의 등록된 자료를 분석하여 국내의 기관식도기형의 현황 즉 발병율 처치 및 치료 결과등에 관한 총체적인 경향을 외국과 비교 분석하여 우리 자료와 구미 보고와의 차별성 및 유사성을 분석하고저 했으며, 다른 하나는 질문서(questionnaires) 분석을 토대로 11차 대한소아외과학회 학술대회에서 토의된 내용을 기초로 회원들의 식도기형의 진단 치료, 술후 관리, 합병증 등에 대한 경험과 의견을 종합하여 고안을 작성하였다. The first national survey on esophageal atresia and tracheoesophageal fistula was conducted to access the current status of its incidence, clinical manifestation, preoperative diagnosis and management, type of its anomaly, associated anomalies, and surgical results and course. The 43 members of the Korea Association of Pediatric Surgeons received questionnaires and registration forms to be filled out on each patient who were born during the three years from January 1, 1992 through December 31, 1994. Questionnaires composed of six broad areas which include 1) preoperative diagnosis and management, 2) surgical technic, 3) long gap, 4) postoperative management, and 5) complications and courses. A total of 148 cases was returned by 28 members working at 23 institutions and 27 members returned questionnaires. We obtained the following results by analysis of the 148 cases of tracheoesophageal anomalies. The incidence of tracheoesophageal anomaly was about 1/10,000-11,000 in 1994, which is one third of that of anorectal malformations in Korea and the distribution of the patients was almost proportionate to the size of each province. Both sexes are about equally affected. Majority of the members make diagnosis of tracheoesophageal anomaly by taking a simple infantogram with a radiopaque tube in upper pouch and a little under half(46%) prefers to perform echocardiography as a part of preoperative management to identify congenital heart disease and lateralize the aorta. Esophageal atresia with distal TEF(87.5%) was by far the most common and there were pure esophageal atresia(5.6%), H-type TEF(2.1%), and so on. About half(49%) of the patients had one or more associated anomalies in addition to tracheoesophageal anomalies. Congenital heart disease was associated in 46 cases(31%), anorectral malfomations in 19 cases(13%), musculoskeletal anomalies in 15 cases(10%), genitourinary anomalies in 10 cases(7%) and gastrointestinal anomalies in 7 cases(5%). Postoperatively, parenteral nutrition and assisted ventilation were given in 66% and 52% of patients respectively. Ninety three(74%) of 126 cases who underwent sugical procedure, experienced one or more complications such as respiratory complication(65%), leak(22%), stricture(21%) and so on. The survival rates related to the Waterston risk categories were 90.2% in group A, 71.4-75% in $B_1$, $B_2$, and $C_1$, groups, and 28% in group $C_2$, and the overall survival rate was 71.4%. Thirty six(28.6%) of 126 cases died of pneumonia/sepsis(12 cases), respiratory failure(12 cases), and congenital heart disease(4 cases). With short term follow-up, 69% of patients have been excellent whereas remainders of the cases have suffered from some sort of morbidity related to gastroesophageal reflux, recurrent respiratory infection, and esophageal stricture.

        에폭시/고무 거시계면에서 장시간 절연파괴전압에 대한 연구

        박우현,이기식 한국전기전자재료학회 2002 전기전자재료학회논문지 Vol.15 No.11

        In this paper, the estimation of lifetime with the various conditions of the interface between toughened epoxy and rubber which are consisting materials of underground power delivery system has been studied. After the measurement of the short time AC interfacial breakdown strength on macro interfaces at room temperature, the breakdown time at several voltages were measured under the constant voltages lower than the short time breakdown voltage. The long time breakdown voltage was calculated by using Inverse Power Law. Two types of interfaces was studied. One was the interface between toughened epoxy and EPDM(Ethylene Prorylene Diene Terpolymer). The other was the interface between toughened epoxy and silicon rubber. Interfacial pressure and roughness of interfaces was determined through the characteristic of short time AC interfacial breakdown strength. Oil condition was no oiled, low viscosity oiled and high viscosity oiled. High viscosity oiled interface between Toughened epoxy and silicon rubber had the best lifetime exponent, 20.69. and the breakdown voltage of this interface after 30 years was evaluated 19.27㎸.

      • 10세 여아에서 발견된 선천성 십이지장 격막 1예

        박우현,최순옥,황진복,Park, Woo-Hyun,Choi, Soon-Ok,Hwang, Jin-Bok 대한소아외과학회 2005 소아외과 Vol.11 No.2

        Chronic duodenal obstruction related to a congenital web is a rare anomaly, and is sometimes difficult to diagnose preoperatively. A case of partial duodenal obstruction by a foreign body in a 10-year-old girl with a congenital duodenal web is presented. She had a year history of intermittent epigastric discomfort without nausea, vomiting or growth retardation. Upper gastrointestinal series and gastroduodenoscopy disclosed a perforated web in the 2nd portion of the duodenum and a dark go stone just proximal to the web. The web was partly excised through a longitudinal duodenotomy crossing over the web. The Ampulla of Vater was located at 7 o'clock on the posterior surface of the duodenal web and was preserved. The duodenum was closed in transverse fashion. In cases of a longstanding duodenal foreign body, a congenital web should be considered.

        지역경찰관의 조직몰입에 영향을 미치는 요인에 관한 연구

        박우현 경찰대학 치안정책연구소 2018 치안정책연구 Vol.32 No.2

        The necessity of organizational commitment of patrol police, which is directly related to enhancement of public security, has been recently emphasized as there have been nation wide requests for improvement of security and enforcement of preventative policing. Greater organizational commitment of patrol police leads to more active results and ethical decision making on the field. This study investigates factors that influence the organizational commitment of patrol police. A multiple regression analysis focusing on eight factors including organizational characteristics, job characteristics, and demographic characteristics has been conducted. Research shows that supervisor feedback, perceived organizational support and job autonomy have a positive correlation with organizational commitment whereas negative perception of citizens and role conflict in law enforcement have a negative correlation with organizational commitment. As such, legislative measures such as supervisor feedback from managing police officers to patrol police, inspection and personnel matters in administrative policing affairs to enhance fairness and organizational support, and delegation of authority along with enhancement of positive relationships with citizens should be introduced and increased. 최근 안전에 대한 국민적 요구 증가와 예방중심의 경찰역할이 강조됨에 따라 현장에서 주민을 직접 접하며 치안서비스 질 향상과 직결된 업무를 하는 지역경찰관의 조직몰입에 대한 중요성이 강조되고 있다. 지역경찰관의 조직몰입이 높을수록 치안현장에서 적극적인 성과 창출을 위해 노력하고, 보다 윤리적인 결정을 할 수 있기 때문이다. 이 연구의 목적은 지역경찰관의 조직몰입에 영향을 미치는 요인을 규명하기 위한 것이다. 이를 위해 조직적 특성과 직무적 특성 등 8개 요인들이 조직몰입에 영향을 미치는 정도를 다중회귀분석을 통해 확인하였다. 연구결과 상사의 피드백과 조직적 지지, 직무자율성이 높을수록 조직몰입도가 높아지는 것으로 나타났고, 시민에 대한 부정적 인식과 법집행에 대한 역할갈등이 낮을수록 조직몰입도는 높아지는 것으로 나타났다. 이에 따른 정책적 제언으로 경찰 관리자의 지역경찰관에 대한 지속적 피드백이 필요하며, 인사와 감찰조사 등 경찰내부 행정 과정에서 공정성 확보를 통해 조직적 지지에 대한 인식을 높이고, 지역경찰관의 자율권을 높이기 위한 권한위임과 함께, 시민사회와의 우호적 관계 강화 등이 필요하다는 것을 제시하였다.

      • 카사이 수술 후 발생한 간내 담관 낭종

        박우현,최순옥,Park, Woo-Hyun,Choi, Soon-Ok 대한소아외과학회 1999 소아외과 Vol.5 No.2

        A 6 and a half year-old girl developed recurrent cholangitis following hepatic portoenterostomy for biliary atresia. Computed tomogram showed an ovoid cyst ($4.5{\times}4.0$ cm in size) in the left hepatic lobe and another tubular dilatation ($2.0{\times}0.8$ cm in size) in the right hepatic lobe. Percutaneous transhepatic cholangiodrainage(PTCD) and cystogram showed an ovoid cyst in the left hepatic lobe (Tsuchida type A), measuring $6.6{\times}5.0$ cm in size. Following drainage and administration of parenteral antibiotics she became afebrile and anicteric. However she continued to drain 45-150 cc of bile per day via the tube over the next 2 weeks. The patient successfully underwent intrahepatic cystojejunostomy with intraoperative ultrasonographic guidance. This case illustrates relapsing cholangitis caused by Tsuchida type A intrahepatic cyst, successfully managed with PTCD followed by an internal drainage procedure.
