Abstract: A method of a wearable device displaying icons is provided. The method includes displaying a plurality of circular icons comprising a first circular icon located in a center area of a touch display in a first size and a second circular icon located outside of the center area of the touch display in a second size smaller than the first size, and based on a direction of a touch input received on the touch display, moving the plurality of circular icons such that the first circular icon is moved to a first position located outside of the center area of the touch display and the second circular icon is moved from a second position located outside the center area of the touch display to the center area of the touch display and enlarged in size from the second size to the first size.

Abstract: The inventive concept relates to an apparatus for treating a substrate. In an embodiment, the apparatus includes a process chamber having a process space in which the substrate is treated with a fluid in a supercritical state, a support unit that supports the substrate in the process space, a fluid supply unit that supplies the fluid into the process space, a filler member disposed to face the substrate placed on the support unit in the process space, and a measurement unit that measures a state in the process space, the measurement unit being provided in the filler member.

Abstract: Provided is a visitor identification system, including: a wireless transmitter; a visitor application; and a management server; wherein the wireless transmitter is installed by a resident and transmits a near field wireless signal; wherein the visitor application receives the near field wireless signal from the wireless transmitter, extracts a first identifier from the wireless transmitter, and transmits the first identifier to the management server, wherein the first identifier is unique to the wireless transmitter; wherein the management server receives the first identifier from the visitor application and performs one or more predetermined tasks so that a resident can verify identity of a visitor.

Abstract: The present invention relates to a composition for topically delivering SDF-1 into the brain, in which the composition comprises a dual ionic pH-sensitive copolymer and a nerve regeneration and protective factor. In the present invention, when a dual ionic pH-sensitive copolymer containing SDF-1 as a nerve regeneration and protective factor is applied to a patient suffering from ischemic stroke as a drug carrier, it induces the effective delivery of the treatment factor to a topical lesion site, and moreover, the risk factors for adverse effects may be cancelled out, so that it can be effectively used as a novel therapeutic agent for ischemic brain diseases.
