Abstract: A low-latency 360 virtual reality (VR) streaming method for estimating a region of interest (ROI) of a user is proposed. The method may include receiving device pose information from a user device, extracting an ROI of a user, based on the device pose information, and generating ROI tile information corresponding to the ROT. The method may also include generating ROI estimation tile information corresponding to a position at which the ROI is to be changed, and requesting, from a streaming server, a tile corresponding to the ROI tile information and the ROI estimation tile information to receive a high-quality tile stream and a low-quality tile stream of full video that includes a low-quality full video tile stream. The method may further include decoding and rendering the high-quality tile stream and the low-quality full video tile stream and providing the rendered video to the user device.

Abstract: An augmented reality (AR) streaming device interoperating with an edge server is proposed. The AR streaming device may include a sensing module including a camera and a certain inertia sensor, a display module streaming AR video, a communication module transmitting or receiving data to or from the edge server and the sensing module. The device may also include a memory and a processor executing a program stored in the memory. When image data and inertia data are obtained through the sensing module, the processor may perform synchronization and encoding on the image data and the inertia data to transmit to the edge server through the communication module. When segmentation rendering-processed AR video is received from the edge server, the processor may perform decoding and blending on the segmentation rendering AR video to perform control to be streamed through the display module.

Abstract: A fronthaul multiplexer according to one aspect of the present invention combines uplink packets in a compressed state that is received from two or more radio units so that the uplink packets are accumulated and combined immediately when received or the uplink packets are recompressed using a compressing method with high compression efficiency when stored in a memory in order to reduce a use amount of memory.

Abstract: The present invention relates to a stable pharmaceutical composition for injection containing docetaxel and a method of preparing the same. More particularly, the present invention relates to a pharmaceutical composition for injection containing docetaxel having better storage stability than conventional medications, which is prepared by dissolving docetaxel, a water-insoluble compound, in distilled water after mixing it with cyclodextrin (CD) and a water-soluble polymer such as hydroxypropyl methylcellulose (HPMC), polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) and lyophilizing the mixture, and a method of preparing the same.

Abstract: The present invention relates to a lyophilized pharmaceutical composition for injection having superior storage stability comprising a taxoid, and a method thereof. More specifically, the present invention relates to a lyophilized pharmaceutical composition for injection having improved solubility and stability of dilution compared to the conventional preparations by dissolving a water-insoluble taxoid in distilled water added with a hydrophilic polymer such as hydroxypropylmethyl cellulose (HPMC), polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) cyclodextrin (CD), and lyophilizing the mixture and a method thereof.

Abstract: The present invention relates to a lyophilized composition with an improved reconstitution time comprising a taxoid and a method thereof. More specifically, the present invention relates to a lyophilized composition with an improved reconstitution time prepared by mixing and dissolving a taxoid; cyclodextrin (CD); a hydrophilic polymer selected from the group consisting of hydroxypropylmethyl CeIIuIoSe (HPMC), polyethylene glycol (PEG), and polyvinylpyrrolidone (PVP); and a bulking agent of saccharides in water for injection; and lyophilizing the mixture, and a method thereof.

Abstract: The present invention relates to salts of a pyrrolopyrimidinone derivative having superior PDE-5 inhibition activity and a process for preparing the same. More particularly, the present invention relates to a crystalline acid addition salt prepared by reacting a pyrrolopyrimidinone derivative with an acid selected from gentisic acid, maleic acid, citric acid, fumaric acid and tartaric acid. With no hygroscopic property and superior long-term storage stability, photostability and thermal stability, the salts of the pyrrolopyrimidinone derivative are appropriate to be prepared into medications and, with superior PDE-5 inhibition activity, are useful for the treatment and prevention of erectile dysfunction, pulmonary arterial hypertension, chronic obstructive pulmonary disease, benign prostatic hypertrophy and lower urinary tract diseases.
