Abstract: Disclosed is a single process for producing hydrogen, carbon monoxide, and carbon from methane by forming gas products comprising hydrogen and carbon monoxide, and solid products comprising carbon and an iron-based catalyst from methane in a methane-containing feedstock through pyrolysis route involving auto-thermal reduction in a rotary kiln-type reactor in the presence of an iron-based catalyst and separating and recovering respective products.

Abstract: Disclosed is a an apparatus for performing smart logistics monitoring including a display unit, a memory, a sensor unit sensing at least one of a temperature, acceleration, humidity, illuminance, inclination, impact, and location of an inside of a logistics vehicle, and a control unit that generates respective status information of a logistics according to a sensed result at a predetermined period, generates a respective QR code indicating the respective status information, and displays the respective QR code on a screen of the display unit. The respective QR code is converted and displayed on the screen depending on an order in which the respective QR code is generated.

Abstract: Provided is a method for creating a virtual reality content, storing the virtual reality content in a transmission buffer, and after that, managing the transmission buffer. A server creates the virtual reality content based on user's motion information, stores the virtual reality content in the transmission buffer and is allowed to modify the virtual reality content stored in the transmission buffer based on subsequently received user's motion information, so that the most recent user's motion information can be appropriately reflected in the virtual reality content. It is possible to provide a more immersive virtual reality service.

Abstract: A light-emitting device package includes a lead frame, a light-emitting device chip, a molding structure, and a plurality of slots. The lead frame includes a first lead and a second lead including metal and spaced apart from each other. The light-emitting device chip is mounted on a first area of the lead frame, which includes a part of the first lead and a part of the second lead. The molding structure includes an outer barrier surrounding an outside of the lead frame and an inner barrier. The plurality of slots are formed in each of the first lead and the second lead. The inner barrier divides the lead from into the first area and a second area. The inner barrier fills between the first lead in the second lead. The second area is located outside of the first area. The plurality of slots are filled by the molding structure.
