  • 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.

  • This study was carried out to find out the proper method of grafting of Magnolia grandiflora L. Magnolia kobus DC. was used as stocks and the modified veneer grafting method in which a flap was attached to the cut surface of scion was adopted. And also the environment of the grafting beds was controlled for giving optimum humidity (90-100%) and temperature ($20-25^{\circ}C$). The results are summarized as follows: 1. Two year-old seedlings of M. kobus were best as stocks for grafting of M. gantiflora. 2. The modified veneer grafting which brought the successful result of 43 to 89.5 percent found to be very efficient method. 3. The environmental control made of vinyl tunnel and screen (lath) was very effective to attain to the excellent result of 89 percent. 4. For scions, one to two year-old branches with well developed winter buds collected just before the time of grafting gave the best results. 5. The optimum season for grafting in Kwangju districts was 15 to 20, April.

  • The Mobile IPv6(MIPv6) has a well-known time gap of packet loss between link down and binding update. To minimize such packet loss, this paper proposes a MIPv6-based dual tunneling mechanism, which keeps exploiting the old tunnel while creating a new tunnel. Superiority of the proposed mechanism is evaluated by quantitative analysis on the lost packets and computer simulation, based on two overlay heterogeneous access networks, such as the UMTS and a WLAN.

  • Pretibial cyst formation is a rare complication after anterior cruciate ligament (ACL) reconstruction and there are only few cases reported. Pretibial cyst can be caused by variable reasons. Foreign body reaction due to breakdown of bio-absorbable screw for fixation, graft necrosis at tibial site, joint fluid leakage to tunnel and incomplete incorporation of graft to bony tunnel. The authors experienced one case of massive pretibial cyst after arthroscopic ACL reconstruction using bio-absorbable interference screw in 38-year-old male patient. Thus, authors report this rare case with literature view.

  • 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.

  • Diurnal courses of $CO_2$ concentration and air temperature in the rice seedbed tunnel covered with polyethylene film, subjected to three different ventilation methods, were traced. Regaredless of ventilation methods, $CO_2$ concentrations in the tunnel on a clear day were lower than that in ambient air, and vice versa before dawn. $CO_2$ concentration during the day was lowest in the tunnel with non-ventilation (NV), followed by horizontal slit ventilation (HSV) and traditional one(TN), reaching down to the lowest level of 58ppm, 155ppm and 272ppm, respectively. Air temperature in the tunnel reached 46$^{\circ}C$ in NV, 37$^{\circ}C$ in HSV and 32$^{\circ}C$ in TV at the daytime when ambient air temperature was 22$^{\circ}C$. Even at night time of ambient air temperature below 15$^{\circ}C$, HSV was more effective than TV in raising the air temperature in the tunnel. The dry weight of 40-day old seedling weighed heaviest in HSV, followed by TV and NV.

  • 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.
