STUDY OBJECTIVE To compare surgical outcomes and overall costs of less invasive methods of hysterectomy to treat benign disease including total vaginal hysterectomy (TVH) and total laparoscopic hysterectomy (TLH) in women with a uterus weighing >500 g. DESIGN Retrospective review of medical records (Canadian Task Force classification III). SETTING(More)
OBJECTIVE We investigated the potential roles of relaxin and subclinical intra-amniotic inflammation by quantitating amniotic fluid relaxin and interleukin-6 concentrations for the prediction of outcome of rescue cerclage in women with cervical incompetence. STUDY DESIGN Cervical incompetence was diagnosed when cervical dilatation exceeded 2 cm with(More)
This study was designed to evaluate the safety and feasibility of prophylactic adnexectomy during vaginal hysterectomy for benign pathology. We retrospectively reviewed medical records of all patients who underwent vaginal hysterectomy (VH) between 2008 and 2010. Clinical comparison of patients who underwent VH with adnexectomy (n = 92) and VH only (n =(More)
With the advent of technology, multi-energy X-ray imaging is promising technique that can reduce the patient's dose and provide functional imaging. Two-dimensional photon-counting detector to provide multi-energy imaging is under development. In this work, we present a material decomposition method using multi-energy images. To acquire multi-energy images,(More)
In this study, the potential for the application of the bioaugmentation to Cd and Zn contaminated sediment was investigated. A batch experiment was performed in the lake sediments augmented with Ralstonia sp. HM-1. The degradation capacity of 18.7 mg-DOC/l/day in the treatment group was bigger than that of the blank group (4.4 mg-DOC/l/day). It can be(More)
‘ Seoul National University’ and ‘ Daewoo Shipbuilding & Marine Engineering’ in Korea jointly developed a mobile welding robot, the ‘ Rail Runner’ (RRX), which is able to freely move in both transverse and longitudinal directions, and perform welding tasks in double hull structures. Recently, RRX2, (the second version of RRX), was presented at ‘Robotics and(More)
AIM To identify the preoperative risk factors affecting the conversion to laparotomy during vaginal hysterectomy (VH) for benign uterine conditions. MATERIAL AND METHODS The charts were reviewed for all patients who underwent VH between 1 January 2003 and 31 December 2008 at Hallym University Hospital, Seoul. RESULTS The rate of conversion to laparotomy(More)
PURPOSE We have developed a new method of segmenting the areas of absorbable implants and bone using region-based segmentation of micro-computed tomography (micro-CT) images, which allowed us to quantify volumetric bone-implant contact (VBIC) and volumetric absorption (VA). MATERIALS AND METHODS The simple threshold technique generally used in micro-CT(More)
Defatted bovine liver (DBL) is a potential source of protein and minerals. Supercritical carbon dioxide (SC-CO2) and a traditional organic solvent method were used to remove lipid from bovine liver, and the quality characteristics of a control bovine liver (CBL), bovine liver defatted by SC-CO2 (DBLSC-CO2) at different pressures, and bovine liver defatted(More)
Defatted soy flour is a potential source of food protein, amino acids, ash and isoflavones. The supercritical carbon dioxide (SC-CO2) and a traditional organic solvent extraction methods were used to remove fat from soy flour, and the quality characteristics of a control soy flour (CSF), defatted soy flour by SC-CO2 (DSFSC-CO2) and defatted soy flour by an(More)
