Abstract: A circularly polarizing plate capable of improving the tone of reflective color sense by using a retardation film having flat dispersion characteristics; and an OLED device comprising the circularly polarizing plate.

Abstract: A head device of three-dimensional modeling equipment is disclosed which has unidirectionally rotating polygon mirrors, can perform biaxial scanning at a high speed due to a combination of the mirrors, can easily control timing and a modeling ray irradiation position, and can enhance modeling precision. A scanning method for a modeling plane using the same is also disclosed.

Abstract: The present invention relates to a composition for parenteral administration, containing donepezil as an active ingredient, and a preparation method therefor. Donepezil, which has been conventionally used for oral or transdermal administration, is prepared as microparticles comprising a biodegradable and biocompatible polymer and a release controller so as to be provided as a pharmaceutical composition for sustained release parenteral administration, thereby enabling in vivo sustained release continuously for 2-12 weeks or more. Therefore, it is possible to reduce the frequency of administration to a patient and maintain an effective concentration in the blood for a long time.

Abstract: The present invention relates to entecavir microspheres and a pharmaceutical composition for parenteral administration containing the same. The entecavir microspheres are manufactured by a method comprising the steps of: dissolving entecavir and a biodegradable biocompatible polymer in at least one solvent; putting the solution of the entecavir and biodegradable biocompatible polymer in a hydrophilic polymer solution, followed by stirring, to form microspheres; and removing the solvent. The entecavir is sufficiently sealed in the entecavir microsphere at approximately 80% or more based on the input amount, and the elution of the entecavir is maintained for 30 days or more, and thus the entecavir microspheres can continuously exhibit efficacy, thereby improving medication compliance of patients.
