목적 : 본 연구는 전자궁적출술 후 질탈출을 부위-특이적인 결함의 개념에 입각하여 치골경부 근막과 직장질 격막의 연결을 통한 골반내 근막의 복원과 자궁천골인대 고정술을 이용한 질탈출의 성공적인 수술적 교정의 방법과 결과를 보고하고자 한다. 연구 방법 : 1999년부터 2001년 8월까지 자궁적출술 후 질궁탈출 증상으로 문화병원 산부인과를 내원, 탈출된 질의 근막을 재건시킨 다음, 이를 자궁천골인대에 고정시킴으로써 질의 부위-특이적인 교정술을 받은 3명의 환자를 대상으로 하였다. 3명중 1명은 개복술을 하였고 2명은 내시경 수술을 하였다. 결과 : 환자의 연령 분포는 49-67세였으며, 수술시간은 평균 113분 (105-125)이었다. 세 환자 모두 수술 후 질의 상태가 해부학 및 기능적으로 정상이었으며, 9일째 특이사항 없이 퇴원하였다. 수술 후 HRT를 시행한 1명을 포함한 3명 모두 각각 24개월, 12개월, 7개월간의 추적 검사에서도 특이한 합병증이나 재발 없이 좋은 경과를 보였다. 결론 : 골반 근막 결손의 복원과 자궁천골인대 고정술은 전자궁적출술 후 질탈출의 교정에 매우 안전하고 효과적이며, 기능적인 방법으로 사료되며, 자궁천골인대를 질탈출 교정에 이용한 연구는 본 연구가 국내에서 처음이다. 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 study, changes in raw water quality is to indicate on the efficiency of ozone treatment of each pollutant as compared to derive the appropriate operating measures. The appropriate selection for injection rate of pre-ozone and did not inject pre-ozone assess changes in the water. When good water quality, you not injected of pre-ozone to evaluate the economic efficiency of electricity and put the most cost-effective ozone concentration were evaluated. Evaluation remove organic matter and chlorophyll-a concentration level in experiments with each factor of the water DOC> 2.5㎎ / L, THMFP> 70㎍ / L, Chl-a> 30㎎/㎥or less constant process, if you do not need to put pre-ozone showed little impact. It also does not put you in pre-ozone appropriate produce enough power rate savings was calculated as approximately 90 million won. Ability to remove organic materials and the ability to produce disinfection byproducts, and cost-effective decisions by considering the concentration of injection if pre-ozone 1 mg/L was investigated by the appropriate concentration of ozone injection.

<P>Unintentional arc faults due to damaged power line cords and loose connections can cause serious fires; thus, they are a safety hazard in residential areas. Therefore, arc fault circuit interrupters are being increasingly used in homes to protect against arcs that may cause fires. In this paper, we analyzed the ignition characteristics of series arcs on the basis of load current. Furthermore, we recommended suitable arc clearing times through characteristics analysis in the Korean residential electric environment. We determined the arc clearing time via the carbonized path arc clearing time test using an ultraviolet signal detecting system according to the test method of the UL 1699 standard. In the experiments, heat-resistant indoor PVC insulated (HIV) wires, which is a type of residential electrical wire, were used as the wire specimens.</P>

An X-Y Channel Dimming LED Backlight with Temperature Compensation for LCD TVs
Won-Sik Oh,Deayoun Cho,Gun-Woo Moon 전력전자학회 2008 전력전자학술대회 논문집 Vol.- No.-
In this paper, an X-Y channel dimming light emitting diode (LED) backlight with temperature compensation for in LCD TVs is proposed. It shows local dimming effects such as reduced power consumption and high dynamic contrast ratio even with much less number of LED drivers than that of the conventional twodimensional local dimming method. Moreover, the image distortion caused by temperature variation of LED block can be effectively compensated. The validity of the proposed dimming method is verified by simulation and experimental results based on a RGB-LED backlight of a 32-inch LCD TV.

A novel adaptive dimming technique with X-Y channels for light emitting diode (LED) backlight system of LCD TVs is proposed. It has matrix structured LED modules with row and column switches to control the brightness of individual division block. It shows local dimming effects such as reduced power consumption and high dynamic contrast ratio with even using much fewer number of LED drivers of proposed method than that of conventional local dimming method. Therefore, low cost and compact design of LED drivers can be achieved. This paper also contains a new adaptive dimming algorithm and image compensation technique for proposed system.
