Comparison of the Thickness and Volume of the Macula and Fovea in Patients with Anisometropic Amblyopia Prior to and after Occlusion Therapy

윤동희,천보영 대한안과학회 2018 Korean Journal of Ophthalmology Vol.32 No.1

To compare the thickness of superior, temporal, inferior, and nasal macula and foveal thickness andvolume in patients with anisometropic amblyopia prior to and after successful occlusion therapy using opticalcoherence tomography (OCT) measurement. Methods: Data were collected prospectively on 30 patients with unilateral anisometropic amblyopia fromDecember 2006 to August 2007. All patients had anisometropia of 2.0 diopters or more. OCT scans wereobtained for all patients at diagnosis. Occlusion therapy was then prescribed and OCT scans were obtainedagain at the time of successful occlusion therapy (defined as interocular difference of <0.1 log units). TheStratus OCT-3 was used to measure fovea thickness and volume and the thickness of superior, temporal,inferior, and nasal macula (within a diameter of 3 mm). Results: Of 30 patients, 22 (mean age of 5.8 years) had successful resolution of amblyopia. The mean durationof occlusion was 11.24 months and mean best-corrected visual acuity at diagnosis was 0.35 ± 0.12 logarithmof the minimum angle of resolution. The mean thicknesses of the superior, temporal, inferior, and nasalmacula prior to and after occlusion were not significantly different (p > 0.05). However, mean foveal volumeprior to occlusion therapy (0.15 ± 0.02 mm3) decreased after occlusion (0.14 ± 0.01 mm3) with statistical significance(Wilcoxon signed rank test, p = 0.025). Conclusions: There was a meaningful decrease in foveal volume in patients with anisometropic amblyopia aftersuccessful occlusion therapy. Whether this decrease relates to visual improvement of the amblyopic eyeremains to be determined. Key Words: Anisometropic amblyopia, Foveal

Design of a generator control system for small nuclear distributed generation

윤동희,장길수 대한전기학회 2011 Journal of Electrical Engineering & Technology Vol.6 No.3

Small-scale reactors have recently attracted attention as a potential power generation source for the future. The Regional Energy Research Institute for Next Generation is currently developing a small-scale reactor called Regional Energy rX 10 MVA (REX-10). The current paper deals with a power system to be used with small-scale reactors for multi-purpose regional energy systems. This small nuclear system can supply electric and thermal energy like a co-generation system. The electrical model of the REX-10 has been developed as a part of the SCADA system. REX-10’s dynamic and electromagnetic performance on the power system is analyzed. Simulations are carried out on a test system based on Ulleung Island’s power system to validate REX-10 availability on a power system. RSCAD/RTDS and PSS/E software tools are used for the simulation.

As part of the 2050 carbon neutrality initiative, the Korean Government promoted the policy of Green Remodeling to reduce carbon emissions from old buildings. This project aims to improve the energy efficiency of old buildings. However, in the process of enacting Green Remodeling, there are many cases where there are no drawings of the building. The conventional method of generating drawings using on-site measurements is time-consuming and labor-intensive, with additional expenses to the owner. The aim of this study was to propose a reverse-engineering approach using laser scanning with mobile devices for small old buildings to create drawings in the form of Building Information Models and validate their usability
