Objective : To report the method and efficacy of the site specific-defects repair in the endopelvic fascia and uterosacral ligament suspension for the correction of posthysterectomy vaginal vault prolapse. Methods : This study was performed in 3 patients with posthyterectomy vaginal vault prolapse who underwent the surgery for the reconstruction of endopelvic fascia and the correction of vault prolapsed vagina by using uterosacral ligament suspension at the department of Obstetrics and Gynecology in Moon-Hwa Hospital. Among them, 1 patient was treated by laparotomy, and 2 patients were treated by laparoscope. Results : The age of patients ranged from 49 to 67 years. The mean operation time was 111 minutes (105-120 minutes). The status of postoperative vagina was normal in all 3 patients, who were discharged 9 days after operation without symptoms. No complication or recurrence were found in them despite long-term follow-up for 24 months, 12 months, 7 months, respectively after operation. One patient has been treated with HRT therapy. Conclusion : The reconstruction of the defect of endopelvic fascia and uterosacral ligament fixation may be very safe, effective, and functional in the correction of vaginal vault prolapse. This study reports the treatment of vaginal vault prolapse using uterosacral ligament within Korea for the first time.

This paper proposes a new induction heating system composed of a thyristor PWM rectifier with a resonant commutation circuit. The operation of proposed system was first analyzed by a theoretical approach with equivalent circuits. And its verification was performed by computer simulations with EMTP. The proposed system can provide a solution for the power factor problem of the existing high-power induction heating system, which uses the line-commutated thyristor bridge in rectifier side.

원유 분해세균에 의한 원유 분해능을 조사한 결과, Xanthomonas campestris M12. Xanthomonas sp. M28, Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, 그리고 Pseudomonas maltophilia N246 등의 순서로 나타났다. Xanthomonas campestris M12, Xanthomonas sp. M28, 그리고 Pseudomonas maltophilia N246 균주 모두 octane 분해시의 온도는 30℃에서 최적이었으며, 최적 pH는 X. campestris M12와 Xanthomonas sp. M28이 7.0∼7.5이었고, P. maltophilia N246이 7.5∼9.0이었다. N246 균주의 최적 NaCl 농도는 3.0∼3.5%이었다. P. maltophilia N246와 X. campestris M12는 모두 플라스미드를 갖고 있음을 확인하였고, N246 균주로부터 플라스미드를 제거하였을 경우 octane 분해능이 소실되었으므로 이 플라스미드 위에 octane 분해 유전자가 있음이 확인되었다. 이 균주의 OCT 플라스미드의 크기는 118kb이었다. 또한, N246 균주는 ampicillin 항생제에 내성을 나타내었다. Xanthomonas campestris M12. Xanthomonas sp. M28. Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, Pseudomonas maltophilia N246 were screened to increase the ability for crude oil utilization. All of these could utilize hexadecane and octane with the exception of N 246 strain for only octane biodegradation. Thus N246, M12, and M28, strains were specially examined for octane oxidation. Octane biodegradation by three strains showed the optimal conditions at 30C, pH7.0∼9.0 and 0.2∼0.3% octane concentration as a substrate. It was found that P. maltophila N246 and X. campestris M12 had plasmid and the cured plasmid from N246 strain lost octane utilization. Therefore, it was confirmed that certain genes for octane utilization were located on OCT plasmid in N246 strain. The size of OCT plasmid in N246 strain was 118 kb. The N246 strain was resistant to ampicillin.

새로 고안한 풍선박리기를 사용한 임상경험

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

p-형 Si(100) 기판 위에 성장시킨 Bi_(3.25)La_(0.75)Ti₃O_(12) (BLT) 박막의 전기적 특성

Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

Author carried out the serological studies on the rabbits serum immunized with human spermatozoa intravenously, intramuscularly, and intravaginal. The results obtained were as follow; All tested rabbits were shownpositive for spermatozoal agglutination tests ad spermatozoal immobilization tests but the titers variously changed on each individuals. Spermatozoal agglutination antibody titers were 10 times higher than spermatozoal immobilization antibody titers. Titers groups immunized intravenously were the highest among groups immunized intramuscularly and intravaginal. The lowest titer was the titer of group immunized intravaginally.

Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.
