Abstract: An electronic device is provided. The electronic device includes a communication module, a memory, and a processor operatively connected with the communication module and the memory, wherein the memory stores instructions which, when executed, cause the processor to, based on application information of a specific application installed in the electronic device, receive app store source change information for updating the specific application, identify whether a higher version of the specific application exists in an app store which is to update the specific application, the app store being identified based on the app store source change information relating to the specific application, and update the specific application by receiving an application package of the higher version from the identified app store.

Abstract: Provided are a refrigerator and a control method thereof. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

Abstract: Disclosed is a method and system for international mobile equipment identity (IMEI) verification and unauthorized terminal detection based on contents of control plane messages exchanged in a process of a terminal that accesses a commercial network in a mobile communication network and the method includes constructing a fingerprint database for each terminal using contents of a control plane message generated in a process of a terminal that accesses a commercial network and a response to the control plane message; and verifying IMEI for an arbitrary terminal that accesses the commercial network using the fingerprint database.

Abstract: Disclosed are a negative testing-based security analysis system for protocol implementation of an LTE device, and a method thereof. According to an embodiment, a negative testing-based security analyzing method for protocol implementation of an LTE device performed by a computer device includes redefining a state of user equipment (UE) as a security abstraction state for a negative test and composing a test case generation rule by analyzing a specification document in redefining the state of the UE as the security abstraction state.

Abstract: A fake base station (FBS) redirection attack method using unicast message injection in a long term evolution (LTE) wireless section and a system thereof are provided. The FBS redirection attack method includes synchronizing with a signal of a commercial base station connected with a target device being an attack target, transmitting an international mobile subscriber identity (IMSI) paging message to the target device using an IMSI of the target deice, and injecting a unicast message including a frequency of an FBS into the target device, before a base station re-access process is completed in the target device which decodes the IMSI paging message.

Abstract: A refrigerator has a door which is selectively transparent by providing a display behind the door and a light source inside the refrigerator that turns on and activates based on user input. When the light source is turned on, the display is activated while the door is closed such that the user sees the display through the door.

Abstract: Provided area refrigerator and a control method thereof. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

Abstract: A refrigerator may include a first door having a first opening and a second door to open and close the first opening. The second door may include a door frame with a second opening and a panel assembly provided at the second opening. The panel assembly may include a front panel, and insulation panel, and a spacer. The door frame may include a recess to receive a knock detection device at a rear side of the front panel, which may detect a user's knocking operation on the panel assembly to turn on a lighting unit to allow the inside of the refrigerator to be seen through the panel assembly. The door frame may also include at least one injection port to inject a foaming solution for molding an insulation provided in an insulation space defined by the door frame and the panel assembly.

Abstract: A refrigerator includes a cabinet configured to form a storage space, a door configured to open and close the cabinet, wherein the door includes an outer plate, a door liner connected to the outer plate, and an opening, a panel assembly configured to cover the opening of the door, wherein the panel assembly includes a front panel, a rear panel spaced apart from a rear surface of the front panel, and a spacer provided between the front panel and the rear panel; the front panel includes a viewing area and a bezel area provided outside the viewing area, a sensor arranged at the bezel area, and an electric wire electrically connected to the sensor and a controller thereof.

Abstract: A refrigerator includes a cabinet, a front panel door part, a drawer part, a driving device located in the front panel door part, and an elevation device located in the drawer part. The elevation device includes a lifting assembly including rods that elevate an object in the drawer part relative to the drawer part. The driving device includes a motor assembly that provides power to the elevation device, a screw assembly connected to the motor assembly, a guide member disposed at a side of the screw assembly and configured to guide movement of a rotation gear of the screw assembly, and a lever connected to the rotation gear and configured to, as the lever rotates about the lever rotation shaft based on the rotation gear moving along the guide member, apply force that causes the rods to rotate about rod rotation shafts to elevate the elevation device.
