Abstract: A terrain structure includes a ground surface layer; a dry layer, a water-containing layer, and a root-growth part. The dry layer is formed under the ground surface layer and has a relatively low water-permeability for allowing water to permeate thereinto from the ground surface layer and/or a relatively low water-containing capacity for containing the water. The water-containing layer is formed under the dry layer, and has a relatively high water-permeability and/or water-containing capacity. The root-growth part has a structure in which a water-permeable material and/or a hygroscopic material is filled between the ground surface layer and the water-containing layer to allow the water supplied to the ground surface layer to permeate into the water-containing layer through the root-growth part, so that when a plant having roots is planted on the ground surface layer, the roots of the plant can grow from the ground surface layer to the water-containing moisture layer.

Abstract: The present invention relates to a method and an apparatus for managing the mobility of a terminal in a mobile agent according to a method for distributive mobility management, and the method according to one embodiment of the present invention comprises: a step for detecting a change in location information of a terminal according to the movement of the terminal and storing the changed location information in a first storage unit; a step for storing, in a second storage unit, an index of the first storage unit in which the changed location information is stored; and a step for transmitting, to another mobile agent, an index value stored in the second storage unit at a point in time at which a predetermined condition is satisfied, and initializing the second storage unit.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure relates to a method and apparatus for selecting a mobility anchor (MA) in a mobile communication system. A method of operating a controller which selects an MA comprises: receiving a bearer configuration request signal from a terminal; acquiring load information for each of a plurality of MAs and mobility information of the terminal; and determining an MA of the terminal on the basis of the load information of each of the plurality of MAs and the mobility information of the terminal.

Abstract: For a mobile terminal and a method for controlling charging thereof, when the remaining power amount of a power supply, including first and second power sources, is less than a minimum power consumption amount required for a call, power is charged using the second power source. The remaining power amount resulting from the charging is compared with a power consumption amount corresponding to a callable time, and information that is associated with the callable time corresponding to a result of the comparison is outputted.

Abstract: The preset invention relates to a system for controlling sounds and images through three-dimensional matrix circuit, which outputs voice and sound signals outputted from a sound generator and amplified by a plurality of amplifiers through a plurality of speakers. The system includes a matrix circuit and a controller. The matrix circuit is configured in a three-dimensional type such that the amplifiers and the speakers to which the voice and sound signals outputted from the sound generator are delivered are connected to each other, changing and adding input/output according to a user's selection. The controller controls various kinds of operations of the speakers and the amplifiers by allowing a user to control the matrix circuit by a multicast method so as to select amplifiers or a combination thereof to be used for broadcasting using a keyboard or a mouse.

Abstract: A mobile terminal includes a power supply including a solar cell; a controller which determines whether charging of power to the power supply can be performed using only the solar cell, controls charging of the power to the power supply using the solar cell when it is determined that the charging of the power can be performed using only the solar cell, and calculates an anticipated charged power amount and an anticipated charging time to reach a certain charging state of the power supply using a power charging speed of the solar cell; and an output unit which outputs charging state notification information that indicates at least one of the calculated anticipated charged power amount and the anticipated charging time, under control of the controller.

Abstract: An apparatus of thinning a glass substrate includes at least one chemical spray member, a chemical supply member, and a bath. The chemical spray member includes a first tube and a second tube enclosing the first tube. The first tube has a plurality of first spray holes disposed along a first direction. The second tube has at least one second spray hole disposed at a lateral portion of the second tube along a second direction. The chemical supply member includes a connection tube and a press pump. The connection tube is coupled to the chemical spray member, and the press pump is disposed at an end portion of the connection tube. The bath includes a chemical receiving member for storing chemicals and a fence disposed on the chemical receiving member. The fence receives the chemical spray member.

Abstract: An apparatus for etching a glass substrate includes a container for receiving an etching solution and at least two rollers disposed in the container. The at least two rollers may face with each other. The glass substrate is inserted between the at least two rollers, and the glass substrate is uniformly etched using the etching solution while revolving the at least two rollers.

Abstract: A window opening and closing assembly capable of controlling an opening angle of the window effectively is disclosed. The assembly comprises a base with a groove along a longitudinal direction thereof, a slider inserted in the groove, an arm rotatably mounted on the base, a handle rotatably placed at a portion of the base and having a worm gear at an end thereof, a worm wheel meshing with the worm gear, and a switch for controlling the location of the slider. Wherein the slider has an angled side inwardly angled at a side of the first sliding portion thereof and the arm has a straight side for restricting a rotation angle thereof. Thus, an opening angle of a window can be controlled by an operation of the straight side and angled side.
