Abstract: A propulsion module of an air mobility vehicle may include a door provided in the housing and opening or closing the opening portion of the housing by a sliding motion of the door; a propeller for providing propulsion to the air mobility vehicle; a link assembly having a first end portion connected to the housing and a second end portion connected to the propeller to pull the propeller into the internal space of the housing through the opening portion or pull the propeller outside the internal space through the opening portion; and a door opening and closing portion coupled to the door and configured for providing an opening and closing force to the door according to an inward-pulling motion or an outward-pulling motion of the propeller.

Abstract: A display device according to one or more embodiments of the disclosure includes a pixel circuit layer including a base layer and circuit elements on the base layer; and a display layer on the pixel circuit layer. The display layer includes a first electrode on the pixel circuit layer; an insulating layer on the first electrode; a second electrode on the insulating layer; a light emitting stacked structure on the second electrode and including a first insulating layer, a second insulating layer, and a light emitting layer between the first insulating layer and the second insulating layer; and a third electrode on the light emitting stacked structure. The light emitting layer includes a two-dimensional material, is separated from the second electrode by the first insulating layer, and is separated from the third electrode by the second insulating layer.

Abstract: The present invention relates to a high-efficiency organic photovoltaic cell using surface plasmon effect of an induced dipole polymer-metal nanoparticle hybrid and a method for fabricating the same. More particularly, it relates to a high-efficiency organic photovoltaic cell whose photoelectric efficiency is maximized by depositing an induced dipole polymer-metal nanoparticle hybrid in or on a hole injection layer, thereby enhancing surface plasmonic properties, and a method for fabricating the same.

Abstract: Various embodiments relate to processing of a function based on a movement state of an electronic device. A method according to an embodiment may include receiving information related to movement of an electronic device or an external device outside the electronic device. The method also includes differently controlling, on the basis of the information, a function of an input device or output device of the electronic device or the external device, an application to be executed in the electronic device or the external device, or at least a part of a function of the application, with respect to a message received by the electronic device, by using at least one process. Other embodiments are possible.

Abstract: The present invention relates to method utilizing a mobile phone as a tool to pay a charge of goods or service rendered through approval of a mobile phone network. According to the method of using the mobile phone to pay a charge on purchasing goods or service, first a buyer uses his or her mobile phone to connect to a payment transaction server, the buyer and merchant store identification code and the bill for the goods is transmitted to the payment transaction server. At this point, the payment transaction server examines the information data received from the mobile phone and determines the approval of the transaction based on the balance corresponding to the buyer identification code, if it is approved the payment transaction server sends the approval notification to a terminal at the merchant store. The information for accessing the terminal is determined depending upon the merchant store identification code.

Abstract: The present invention relates to a process for treatment of high concentrated waste water from animal husbandry, human excretion and other high organic waste. This process includes warming, anaerobic digestion, separation with ultra filtration (UF)/reversed osmosis (RO) membranes. The residual solution after RO separation is the raw material of liquid fertilizer for water culture and foliar spray.
