A display apparatus including a display configured to display a pointing object, a communicator configured to perform communication with a remote control device which recognizes a movement and transmits a signal corresponding to the recognized movement, and a processor configured to control a moving state of the pointing object based on the signal received from the remote control device. The processor controls the moving state of the pointing object according to a relative coordinate method for a first area where a screen of the display is included, and controls the moving state of the pointing object according to an absolute coordinate method for a second area outside the first area.

Display apparatus and control method thereof

A user terminal device, a method for controlling the user terminal device, and a system for providing content are disclosed. The user terminal device may include a communicator configured to communicate with a display device, a detector configured to detect a distance between the user terminal device and the display device, a plurality of inputters configured to receive input of a user command, and a controller. The controller is configured to activate at least one of the plurality of inputters in response to a detection that the user terminal is within a predetermined distance with respect to the display device. The user terminal device may control an operation of the display device according to the distance between the user terminal device and the display device.

User terminal device and method for control thereof and system for providing contents

The present invention relates to a method for preparing a curable bicyclic compound derived from biomass. The method includes preparing starting materials furan and methyl acrylate by preparing furan from hemicellulose extracted from biomass, and methyl acrylate from glycerol generated from biomass, preparing an intermediate compound comprising a bicycle and an alcohol functional group by reacting the furan and the methyl acrylate through a Diels-Alder reaction and consecutive reduction, and preparing a curable bicyclic compound that includes the bicycle and an epoxide functional group by reacting the intermediate compound and epichlorohydrin.

The present disclosure relates to an acid catalyst composition for producing 5-chloromethyl-2-furfural from galactan derived from seaweed and a method for producing 5-chloromethyl-2-furfural from galactan derived from seaweed on a two component phase using the acid catalyst, the acid catalyst composition for producing 5-chloromethyl-2-furfural from galactan derived from seaweed including organic solvent and dilute hydrochloric acid, a concentration of the dilute hydrochloric acid being 4N to 8N (normal). According to the present disclosure, there is an advantage of converting 5-chloromethyl-2-furfural from galactan derived from seaweed by means of a single process by mixing dilute hydrochloric acid and organic solvent by an optimal ratio, unlike conventional methods for producing 5-chloromethyl-2-furfural that had to go through a multi-phase process of preconditioning and saccharification.

Disclosed is a method of preparing a petroleum-alternative bio fuel material such as 5-hydroxymethyl-2-furfural (HMF), 5-alkoxymethyl-2-furfural, levulinic acid alkil ester, etc. through a single process without saccharification, using a catalyst conversion reaction, from galactan that can be massively supplied at low costs and extracted from macroalgae of marine reusable resources. Thus, the macroalgae of the marine biomass resources is used so that a carbon source can be more easily extracted than that of a lignocellulosic biomass resource without a problem of having an effect on grain price like a crop-based biomass.

Provided is a disdrometer system having a three-dimensional laser array unit, including: a plurality of laser transmitting parts which are arranged on an inner side of a cylindrical body to generate a laser beam; a plurality of laser receiving parts which are arranged on the inner side of the cylindrical body to correspond to the laser transmitting parts; and a laser control part which converts a cut-off signal of the laser beam, which is cut-off by precipitation drops flowing into the inner side of the cylindrical body, into an electrical signal, and records the converted electrical signal. Thus, the disdrometer system has an effect that the shape, volume, number, falling velocity of precipitation drops, and the intensity, density and weight of rainfall can be integrally measured.
