Objectives: The aim of this study is to introduce protocols for choosing trans-arterial embolization (TAE) or surgical hemostasis as an initial therapy for obstetric hemorrhage. Materials and Methods: From 2002 to 2011 at our hospital, the medical records of the patients who underwent TAE or surgical hemostasis for obstetric hemorrhage were reviewed to assess the following data: The causes of obstetric hemorrhage, Shock Index (SI) and obstetrical disseminated intra-vascular coagulation (DIC) score, amount of bleeding, transfusion, and operation time. Results: Twenty-five patients underwent TAE and six underwent surgical hemostasis. SI and obstetrical DIC score of the TAE group were 1.0 (0.4 - 2.2) and 6.0 (1 - 32), respectively. They were significantly lower than those of the surgical hemostasis group (SI: 1.6, obstetrical DIC score: 12.5, p < 0.05). Though the hemorrhage could be controlled sufficiently in 23 cases of the TAE group, 5 cases went into shock during TAE. The SI and obstetrical DIC score of shock group were 1.2 (1 - 2) and 10 (2 - 32), respectively. Conclusion: Though TAE is a useful therapy to control obstetric inevitable hemorrhage, special attention should be paid to the vital signs during TAE, especially in cases where SI and/or obstetrical DIC score are higher than 1.2 and 10, respectively.

A 75-year-old woman complained of anuria and a sense of discomfort with severe pelvic organ prolapse (POP). We planned tension-free vaginal mesh (TVM) surgery after curing mucosal defects and completing treatment for diabetes mellitus. Anuria and pyelonephritis relapsed repeatedly due to the failure of ring pessary therapy. Surgical treatment was required emergently. We performed a total laparoscopic hysterectomy and uterosacral ligament colpo-suspension (Shull’s method). Although the vaginal apex was supported to a good position, cystocele occurred six months after the initial surgery. A TVM procedure for recurrent cystocele was performed after curing the mucosal defects, and after the improvement of glycemic control. Transvaginal native tissue repair has the advantages of low risk of ureter injury, firm colpo-suspension, and no need for mesh usage. On the other hand, it is not good at treating cystocele. Transvaginal native tissue repair should prove to be a useful surgical option for apical support without mesh.

The experimental results by the simulated PV (photovoltaic) system for understanding the cause of disconnection when instantaneous voltage sag occurs are reported in this study. Moreover, it is understood that the PCS with the voltage phase jump detection method which is one of the main causes of the disconnection. We modeled it in the simulation. When fault occurs, even though the residual voltage is more than 20% and the voltage sag time is within 1.0 s, the PCS disconnected by the voltage phase jump detection was confirmed in the simulation results. If a large number of PV systems are interconnected in the power system, this study is verified through the simulation that the interaction caused by the disconnection which generated by the voltage phase jump detection. This study is proposed threshold limit value of islanding detection. The validity of proposed method was verified through the simulation in this study.
