OBJECTIVES To provide the practicing surgeon with data to make an informed economic decision regarding conversion from analog to digital photography. METHODS A cost analysis of photography based on 35-mm vs digital platforms (low-, medium-, and high-cost hardware). RESULTS Break-even thresholds for the investment in a digital platform of low, medium, and high costs were 3674, 15,789, and 34...
“South Korea is the plastic surgery capital of the world.” This is how Korean plastic surgery was described in the Washington Post in 2015 [1]. Korea seems to be consolidating its position as a leading plastic surgery nation.

After initiating a trial series of art classes for plastic surgery residents, the authors recommend that art education, including hands-on training and art appreciation, becomes part of an aesthetic surgery training curriculum.
The Milestone Project in plastic surgery was created to define training outcomes and measure progress as a trainee progresses from novice to expert. The Plastic Surgery Milestones represent a framework with graduated measures to ensure the learner and program faculty know the expected intermediate and long-term competencies, and can more accurately measure where an individual is on the expected...
Strengthening of existing circular reinforced concrete columns by CFRP confinement
This study was conducted to evaluate the effects of different levels of Mentha piperita extract on growth factors, survival rate and body composition of Rutilus frisii kutum fry. For this purpose, four groups of fish with mean weight of 1.12± 0.14 g were raised for 56 days in plastic tanks (40 fish to each tank) and feeding with different levels of M. piperita with concentrations of 0, 1, 2.0 a...
This experiment was done to determine the effectd of growth stage on chemical composition and processing by NaOH and CaOH2 on ruminally degradability of Haloxylon sp. pasture plant in seeding stage. The enough amount of Haloxylon in 3 vegetation stages was prepared from Amari SarChah in May and October and December of 2010. The chemical composition of Haloxylon sp. was determined in three stage...
Objective: The aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy.Methods: A Siemens Primus linear accelerator and a phantom were simulated using MCNPX Monte Carlo code. In a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. The tissues included muscle (ske...
