The repair of incompetent venous valves using venocuff sleeve is a new, simple technique. The venocuff sleeve is usually implanted around the valve of the saphenofemoral junction in the primary great saphenous varicose vein. The material of venocuff was PTFE(Gore-Tex^(12)), with an average of 1.2-1.5cm in width and 0.5-0.6 cm in diameter. Two hemodynamic tests of venous pressure and photoplethys- mography(PPG) were performed in 13 patients who underwent venocuff sleeve method preand post-operatively. Venous refilling times were checked with superficial venous pressure and PPG, respectively. The average follow up duration was 13 months(1-27 months). The results were as follows: The male to female ratio was 7 to 6 and the average age was 43.2 years with a range of 20∼63 years. The clinical symptoms of venous engorgement(N=12), calf pain(N=3) and tortuous veins(N=4) were all improved after operation, but the swelling(N=2) was improved in one case. The Mean venous pressure refilling times with the superficial venous pressure and PPG were 9.0±1.5 and 8.8±1.1 second at preoperative, 20.5±2.6 and 20.0±3.0 second at postoperative test, respectively(p$lt;0.01). Recurrence was recognized in one patient. In conclusion, treatment of the primary varicose vein using venocuff sleeve may be a simple, less invasive, easy, and effective method that can preserve the valvular competence. The great saphenous vein can also preserve for graft surgery of the coronary and peripheral vessel.

Objective : Eleven patients treated with posterior cerebral artery[PCA] aneurysm during 6.3-years period are retrospectively reviewed to determine treatment outcome. Methods : Eleven patients with PCA aneurysm were treated from January 1998 to May 2004. Their medical records and radiologic studies were reviewed retrospectively. The records of these patients were analysed with particular reference to their demographic details, mode of presentation, and treatment outcome. Results : Of the 11 patients, 8 patients presented with symptoms related aneurysmal bleeding. Three patients had unruptured PCA aneurysms. Open or endovascular surgery was performed in 9 patients; None of these patients exhibited a third nerve palsy, visual field deficit, or hemiparesis at the time of presentation. Postoperatively, 2 made a good recovery, 2 had a moderate disability because of cerebral infarction after surgery, and 5 had a severe disability because of cerebral infarction after surgery. Of 2 conservatively treated patients, 1 was doing well but the other died as a result of brain swelling. Conclusion : The treatment of the PCA aneurysms is difficult regardless of the aneurysmal size, site, and treatment modality. All reasonable treatment to reduce the risk of associated morbidity should be considered.

Background: The submcosal lifting gel (Cook Medical) is a novel injectate for submucosal lifting of gastrointestinal lesions. It has been proven to be an effective lifting solution to facilitate tissue resection and auto-dissection of submucosal layer after its submucosal injection. The aim of this study was to evaluate the effi cacy of a novel submucosal lifting gel for performing EMR-P in the case of large lesion. Methods: This study was designed as a prospective, controlled, animal, and pilot study. A total of 31 artificial lesions were created on body of stomach by electrocautery marking with endoscopic ruler in fi ve live micro-pigs. Results: All 31 lesions were successfully resected by EMR-P method with a new submucosal lifting gel by two experienced endoscopists in 3 micro-pigs. The long axis of the mean size of resected specimens was 3.7 (± 0.3) cm, 4.6 (± 0.5) cm, and 5.1 (± 0.7) cm in the group 1, 2 and 3 respectively. The mean circumferential resection time was signifi cantly longer in the group 3 in comparison with group 1 and 2. The mean total procedure time and amount of injection were signifi cant difference between three groups. However, the mean submucosal injection time was no signifi cant difference three groups. The en bloc rate of each group was 100% (6/6), 66.7% (4/6), and 40% (2/5) in the group 1, 2, and 3 respectively. There was a perforation during circumferential cutting in group 2. However, there was no immediate bleeding and perforation after EMR Conclusions: In a porcine model, a new submucosal lifting gel seems to improve the en bloc rate for performing EMR-P in large lesion, especially 3 cm in diameter.

Congenital duodenal obstruction in the newborn infant may be due to a variety of causes. Duodenal obstruction often presents with bilious vomiting and upper abdominal distention. Diagnosis is usually established on plain x-ray of the abdomen by the classic finding of the double-bubble. In the period July 1986 ot June 1990, 16 patients with congenital duodenal obstruction were operated and the following results were obtained. 1. Sixteen patients were comprised of 11 males and 5 females, the ratio of male and female was2.2:1. 2. Thirteen patients(81%) had been admitted to our hospital during one month of life. 3. Congenital duodenal obstruction was in 16 cases ; malrotation in eight(50%), annular pancreas in six(38%), type 1 atresia in one(6%), and wind-sock anomaly in one(6%). 4. There were two premature patients and six patients of small for gestational age. 5. Overall, bilious vomiting, occurring in three fourths, was the single most frequent presenting comp-laint. 6. Polyhydramnios occurred in two of the patients. 7. Diagnosis was possible with clinical symptom and simple abdomen. 8. The operative procedures performed were ; duodenoduodenostomy in five, duodenojejunostomy in two, excision of wind-sock membrane in one, and Ladd's procedure in eight. 9. A total of ten asociated congenital anomalies were found in six patients. 10. Postoperative complications occurred in five cases(31%).

The Closed Control System, which uses exclusive network and protocol, have been adopted in TM/TC systems. However, the Closed Control System is known that it is not able to support the integration in the water management automation. There are two methods in integration solution in different types of TM/TC System. One solution is hardware system integration that is very expensive and impractical. The other solution is software system integration that uses OLE for Process Control(OPC). In this study, we recommend OPC solution, for KARICO water management, that is the practical and efficient. KARICO is using OPC technology in MMI(Man machine Interface) and water management program. Through this technology, the real-time status of reservoir, pumping station and canal can be achieved without difficulty.
