The object of the present invention is to provide a light-emitting device that emits phosphorescence with high efficiency. The processor-readable storage medium may include one or more programming instructions for performing a method of evaluating an impact of consolidating a plurality of print shops on inventory levels. The first and second ground plates comprise plate sections each having a first surface and a second surface on the opposite side of the first surface, and the first surfaces face each other. The invention also provides an ocular device coated with at least one kinase inhibitor. The location of the contact points is controlled such that a key bar stress at the connection points is also minimized.
