Abstract: Provided is a heater for an aerosol-generating device including a first electrically conductive pattern configured to perform heating and a second electrically conductive pattern arranged in parallel with the first electrically conductive pattern. The first electrically conductive pattern and/or the second electrically conductive pattern may include a material having a relatively small resistance temperature coefficient. Accordingly, a temperature increase rate of the heater may be greatly improved.

Abstract: Disclosed is a communication method that prevents excess message transmission and improves the efficiency of a communication system. The method includes transmitting a first connection request message for a service connection to a network by an electronic device, receiving a first connection reject message for the first connection request from the network, abstaining from retransmission of the connection request to the network based on the first connection reject message, determining whether an operation configured in the electronic device belongs to a condition set by the electronic device based on at least a portion of the abstinence operation, and when determining that the operation belongs to the condition, transmitting a second connection request message to the network.

Abstract: An apparatus and a method for moving a web page in a web browser of a terminal that permits root domain movement by a single input. The apparatus includes a memory, a controller, and a display unit. The memory stores a first list for managing a root domain movement history, and a second list for managing a page movement history. The controller updates at least one of the first list and the second list whenever a web page access occurs, and when moving root domain is selected by a user, directly accesses a web page of the root domain with reference to the first list. The display unit displays the accessed web page.
