Residual Image Reduction Using Electric Field Shield Metal in Plastic Organic Light-Emitting Diode Display.

A plastic organic light-emitting diode display is a device that emits light in an organic layer in proportion to the amount of current applied from a thin film transistor, which constitutes a pixel. However, it was confirmed that the residual image was shown by the operation of the thin film transistor. To suppress residual image, the effect of electric field was studied in operation of a-IGZO thin film transistor.

Prospective evaluation of the effectiveness of a home-based program of isometric strengthening exercises: 12-month follow-up.

Background: The aim of this prospective randomized clinical trial was to investigate the efficacy of a home-based program of isometric strengthening exercises for the treatment of the lateral epicondylitis (LE) of the distal humerus. We hypothesized that 1) use of isometric strengthening exercises would result in clinical benefits similar to those provided by medication and pain relief and 2) functional improvements after exercise would be time-dependent.

Methods: Patients were assigned to one of two groups: 1) an immediate physical therapy group (group I), or 2) a delayed physical therapy group (group D).

Comparison of the clinical outcomes of single- and double-row repairs in rotator cuff tears.

Background: Although research has demonstrated the superiority of double-row rotator cuff repair over single-row methods from a biological and mechanical point of view, few studies have compared clinical outcome of the 2 methods, and no articles have been published describing the superiority of double-row methods in clinical aspects.

Hypothesis: Arthroscopic double-row repair of a rotator cuff tear has superior clinical outcome to single-row repair.

Study Design: Cohort study; Level of evidence, 2.

Radial nerve palsy after arthroscopic anterior capsular release for degenerative elbow contracture.

Because the use of arthroscopy has increased recently for the treatment of elbow lesions, reports of complications have become more common. Nerve injury after arthroscopic anterior capsular release is an extremely rare complication, with 4 reported cases worldwide. We usually use a sharp-tipped electrocautery device with a 0.
