We have recently operated 6 year-old male patient who had double outlet right ventricle with dextrocardia, situs inversus, pulmonary stenosis and 2 ventricular septal defects. Rastelli operation was performed by internal baffling with Cooley woven Dacron and tunnel grafting with Hancock valved conduit between the right ventricle and the main pulmonary artery.His postoperative course was uneventful. He was discharged in good conditions on P.O.D. #33.

When the train travels quickly, in the center of city subway tunnel the strong wind blows caused by its piston effect, and the train wind blows while train enter the subway station with this effect. The train wind brings unpleasantness which passenger's hair wavering and the skirts of passengers flapping severely, and critical situations to the old and the weak people. It considers seriously like this, the research is meant to find extent of subway train wind influence on the passengers from the part Seoul subway stations.

We experienced a case of partial anomalous pulmonary venous return from righ lung to inferior vena cava, which combined with Scimitar sign in 18 years old female patient. Diagnostic procedures were simple chest x-ray chest CT, and cardiac catheterization. We redirected the anomalous venous flow from inferior vena cava to left atrium through the intracardiac tunnel which was made with autologous pericardium. Postoperative course was not eventful.

Two patients with uncorrectable cyanotic cardiac anomalies underwent total cavopulmonary shunt[modified Fontan operation]. Case I was a 14 years old male with dyspnea and cyanosis after birth. Aortogram showed TGA combined with overriding of aorta, pulmonary stenosis, complete atrioventricular septal defect, interruption of inferior vena cava, and situs inversus totalis. We had performed total cavopulmonary shunt using with 16 mm Gortex Graft in single atrium to bypass the hepatic vein to pulmonary artery. Postoperatively, patient sustained low PaCO2 and low cardiac output and then expired at 19th postoperative day. The cause of death of the patient would be low cardiac output. Case II was a 6 years old female with dyspnea and cyanosis after birth. Aortogram showed tricuspid atresia[Type IIb], transposition of great arteries, atrial septal defect, ventricular septal defect and pulmonary stenosis, We had performed total cavo-pulmonary shunt using intraatrial baffle[tunnel] with Goretex patch. The postoperative course of this patient was good without event.

표준 Mobile IPv6(MIPv6)는 이종 접속 망간 호스트 이동성을 지원할 때, 핸드오프(handoff) 시 발생하는 링크 단절과 터널 변경시점의 차이로 인해 패킷 손실을 유발한다. 다시 말해, 새로운 터널 생성과 라우팅 갱신 과정에서 추가적인 패킷 손실이 발생하게 된다. 본 논문은 이 때 발생하는 상 하향 패킷 손실을 최소화하는 Mobile IPv6기반 이원적 터널 기법을 제안한다. 그래서, UMTS 광대역 망과 WLAN 협대역 망을 이종 접속 망 모델로 설정하고, 사이에서 Mobile IPv6기반 핸드오프 시 발생하는 패킷 손실을 정량적 분석과 컴퓨터 모의실험 측정을 통해 제안 기법의 성능 향상을 입증한다.

This is one case report of the extremely rare congenital cardiac malformation, Double-outlet of left ventricle in corrected transposition of great arteries. 11-year-old boy complained acrocyanosis and exertional dyspnea, the parents noticed cyanosis since birth. Physical examination revealed acrocyanosis, clubbed fingers and toes, G-III pansystolic murmur on 2nd and 3rd ICS, LSB. Right heart catheterization revealed significant $O_2$ jump in ventricular level. Right and left ventriculography showed the both catheters arriving in the same ventricle i.e. anterior chamber, morphological left ventricle was in right and anterior position, simultaneous visualization of aorta and pulmonary artery and aorta locating anterior and right side of pulmonary artery. Echo cardiogram surely disclosed interventricular septum. Conclusively it was clarified that the patient has Double-outlet of left ventricle and corrected transposition of great arteries [S.L.D.]. Operation was performed to correct the anomalies under extracorporeal circulation with intermittent moderate hypothermia. Right-sided ventriculotomy disclosed the following findings. 1. Right-sided ventricle was morphological left ventricle. 2. Left-sided ventricle was morphological right ventricle. 3. Right side atrioventricular valve was bicuspid. 4. Left side atrioventricular valve was tricuspid. 5. Aortic valve was superior, anterior and right side of pulmonary valve. 6. Subpulmonary membranous stenosis. 7. Non-committed ventricular septal defect. We made a tunnel between VSD and aorta with Teflon patch so that arterial blood comes through VSD and the tunnel into aorta. After correction the patient needed assisted circulation for 135 min. to have adequate blood pressure. Postoperatively by any means, adequate blood pressure could not be maintained and expired in the evening of operation day.

터널식 보온절충못자리 육묘에서 고온장해를 막기 위한 바람트기는 묘의 광합성과 관련하여 상내 $CO_2$ 공급 또한 중요하므로 바람트기 방법에 따른 상내 온도와 $CO_2$ 농도의 낮 동안의 변화를 알아보고자 본 실험을 수행하였다. 1. 맑은 날(5월 20일)에 조사한 바람트기 방법별 상내 $CO_2$ 농도는 바람트기 방법에 따라 뚜렷한 차이를 보였는데, 무통풍이 가장 낮았고, 관행이 가장 높았으며, 가로일자찢기는 중간 정도였다. 상내 $CO_2$ 농도가 가장 낮아진 시각은 무통풍에서는 10:30시에 58ppm, 가로일자찢기에서는 15:30시에 155ppm, 관행은 17: 30시에 272ppm 이었다. 광합성이 이루어지는 낮 동안의 상내 $CO_2$의 평균 농도는 외기 15.74m ㏖/㎥에 비하여 무통풍은 3.27m ㏖/㎥, 가로일자찢기는 12.81m ㏖/㎥이었다. 2. 외기온도에 대한 상내 기온울 보면 무통풍에서 외기가 22$^{\circ}C$일 때 46$^{\circ}C$까지 높아졌으며, 이때 가로일자찢기는 37$^{\circ}C$였고, 관행은 32$^{\circ}C$였다. 상내 기온이 15$^{\circ}C$ 이하에서는 가로일자찢기가 관행보다 더 큰 보온효과를 보였다. 3. 해돋이 전 상내 기온이 1$0^{\circ}C$-15$^{\circ}C$로 비교적 낮은 때 $CO_2$ 농도는 높은 편이었지만, 해독이후 상내 기온이 2$0^{\circ}C$까지 높아지고 동시에 광합성이 이루어지게 되면 급격히 감소하다가 2$0^{\circ}C$ 이상으로 높아짐에 따라 $CO_2$ 농도는 서서히 감소하는 경향이었다. 4. 40일묘의 묘소질은 건물중, 충실도 모두 가로일자찢기에 의한 바람트기가 가장 높았고, 관행이 그 다음이었으며, 무통풍이 가장 낮았다. 5. 보온 못자리의 바람트기는 튼튼한 모기르기를 위한 보온, 고온장해 방지 , $CO_2$ 공급 등의 중요성을 동등하게 인정하고 관리하여야 할 것으로 판단된다.

Purpose: Nerve conduction study (NCS) test is a standard diagnostic study of the tarsal tunnel syndrome. The purpose of this study was to determine the relation between the results of the NCS and postoperative clinical results. Materials and Methods: From June 2004 to July 2015, 104 patients were diagnosed with tarsal tunnel syndrome and treated surgically. Of 104 patients diagnosed through NCS preoperatively and postoperatively, 41 patients were included in this study. There were 23 male and 18 female patients with mean age of 49.2 years old and the average follow-up period was 15.5 months. NCS, pain visual analogue scale (VAS) score, and subjective satisfaction were examined preoperatively and postoperatively. Results: On the preoperative NCS, 32 patients (78.0%) were positive and 9 patients (22.0%) were negative, and 32 positive NCS patients consisted of 9 positive (28.1%), 16 improved (50.0%), and 7 negative (21.9%) postoperatively. VAS score was 7.4 preoperatively and 4.4 postoperatively. According to satisfaction, there were 8 excellent (19.5%), 21 good (51.2%), 6 fair (14.6%), and 6 poor (14.6%) patients. For 32 patients who were positive on the preoperative NCS, the postoperative VAS score was 4.87 and there were 7 excellent (21.9%), 16 good (50.0%), 4 fair (12.5%), and 5 poor (15.6%) patients. Sixteen patients were negative on the postoperative NCS, with a VAS score of 3.75, 1 excellent (6.3%), 11 good (68.8%), 2 fair (12.5%), and 2 poor (12.5%). There was no statistical correlation between the preoperative NCS and postoperative VAS score (p=0.10), between preoperative NCS and postoperative satisfaction (p=0.799), between preoperative NCS and postoperative VAS score (p=0.487), and between postoperative NCS and postoperative satisfaction (p=0.251). Conclusion: For patients diagnosed with tarsal tunnel syndrome and treated surgically, NCS showed little correlation with postoperative result.
