Abstract: A transparent conductor according to an exemplary embodiment of the present invention includes a transparent substrate, and a transparent conductive pattern formed on the transparent substrate, and the transparent conductor includes a nanostructure on an upper surface of at least one of the transparent substrate and the transparent conductive pattern.

Abstract: Provided are an IoT device and an IoT communication method. The IoT device may: be connected to a server via NAT; execute a first session for service connection; and execute a second session for calculating a particular keep-alive value corresponding to a period in which an IP address mapped by the NAT expires. The present invention can minimize transmission of a keep-alive value of an IoT device, enables an IoT device to share a particular keep-alive value with other IoT devices, and thus can minimize a network load which may be caused by a keep-alive value of an IoT communication device.

Abstract: Provided is a light therapy device capable of further maximizing a scattering effect, having enhanced durability, and exhibiting energy uniformity sufficient for use as a light therapy device.
