PURPOSE To determine whether retinal nerve fiber layer defect (RNFLD) is associated with cerebral small vessel diseases (SVDs) and to identify risk factors for RNFLD. METHODS A total of 4421 Korean subjects who underwent health checkups including brain magnetic resonance imaging (MRI) and fundus photography between January 2008 and October 2009 were included in this study. Co-morbid systemic ...

In and Ga impurities substitutional to Al in the oxide layer resulting from diffusion out of the substrate are identified as candidates for electron traps under inversion at In0.53Ga0.47As/Al2O3 interfaces. Through density-functional calculations, these defects are found to be thermodynamically stable in amorphous Al2O3 and to be able to capture two electrons in a dangling bond upon breaking bo...

We present a novel iris repair technique for the management of iris transillumination defects secondary to iris pigment epithelium (IPE) loss, which includes iris oversewing over the defect through partial iris stromal bites with 10-0 polypropylene. This technique provides a healthy layer of iris covering the transillumination defect without the creation of new defects on the contiguous IPE.

OBJECTIVES To repair unexpected damage of the pulmonary artery (PA) during thoracic surgery, fibrinogen/thrombin-based collagen fleece (TachoComb(®) [TC]) can be applied as a haemostatic material. The progression of vessel restoration with TC has not been elucidated. In this study, we investigate details of the healing process with TC after PA injury using a canine model. METHODS Left thoraco...

We report a rare case of traumatic abdominal wall hernia (TAWH) caused by a traffic accident. A 47-year-old woman presented to the emergency room soon after a traffic accident. She complained of diffuse, dull abdominal pain and mild nausea. She had no history of prior abdominal surgery or hernia. We found a bulging mass on her right abdomen. Plain abdominal films demonstrated a protrusion of ho...

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...

Photonic defect modes induced by in situ formation of an ill-defined defect layer is demonstrated in a cholesteric liquid crystal (CLC). The local deformation of the one-dimensionally periodic helical structure is achieved by means of the thermodielectric effect, which alters the pitch in the middle of the cholesteric structure. The defect-mode peak in the photonic band gap appears in the trans...

Software defect prediction has turned into an expected requirement for organizations to guarantee quality and reliability of software products. The early defect prediction can encourage managers to amend and improve reliability of product. Methodologies, for example, machine learning and neural network have ended up as eminent solution for training and classification of data and can be importan...

Subchondral defect repair is a multitask challenge requiring the simultaneous regeneration of cartilage and bone. Herein, we describe the features of a hydrogel system designed to simultaneously induce the endogenous regeneration of hyaline cartilage and subchondral bone. The system was constructed as two layers, spatially presenting the chondroinductive transforming growth factor-β1 (TGF-β1) i...

The performance of the Cu2ZnSnS4 based solar cell is investigated using a simulation program called Solar Cell Capacitance Simulator (SCAPS). The cell structure is based on Cu2ZnSnS4 (CZTS) compound semiconductor as the absorber layer, n-doped and un-doped (i) zinc oxide as the window layer, In2S3 as the buffer layer. We study the influence of the defect density, carrier density, thickness of t...
