Abstract: An optical member includes a light guide plate, a wavelength conversion layer, and a reflective tape. The wavelength conversion layer is disposed on an upper surface of the light guide plate. The reflective tape includes a first side portion covering first side surfaces of the light guide plate and the wavelength conversion layer. The reflective tape includes a first surface and a second surface. The first surface is configured to reflect light of a first wavelength band and light of a second wavelength band different from the first wavelength band. The second surface is configured to absorb the light of the first wavelength band.

Abstract: A portable electronic device is provided. The portable electronic device includes a display, a memory to store a first set of applications and a second set of applications, the first set of applications and the second set of applications to be executed in a first operation mode and a second operation mode of a same operating system, respectively, and a processor.

Abstract: Disclosed herein is a method and system for leading composition capable of being performed by the leading of an instructor with respect to the composition prepared and submitted by a learner, in which errors are extracted from the composition, so that teaching and learning composition are performed through correction, error remediation, and index study based on the errors. The method for teaching and learning composition comprises constructing a learning composition database including an index database wherein index information associated with the composition is stored, providing a learning topic to a learner with reference to the leading composition database and receiving correction information associated with the composition prepared by the learner from an instructor, extracting the index information from the index database included in the leading composition database; and providing instruction information including the correction information and the index information to the learner.
