Abstract: There is provided an object attribute-based watermarking method for preventing leakage of a digital content. A video watermarking method according to an embodiment may acquire a requested video and watermarking information upon receiving a request for video streaming from a user, may determine some of objects appearing in the video according to the watermarking information, may transform attributes of the determined objects, and may stream the transformed video. Accordingly, by watermarking an attribute of an object appearing in a video differently according to a user and providing the video, a watermark may be difficult to perceive, robustness against various attacks may be guaranteed, and a leakage path of a content may be checked.

Abstract: Proposed is a microplastic detection sensor for detecting information about microplastic contained in a sample. The sensor may include a fluidic channel substrate including an inlet and an outlet, and a plurality of RF resonance structures. The inlet may be formed on one end of the fluidic channel substrate, and the outlet may be formed on the other end. The fluidic channel substrate may have a microfluidic channel formed therein to connect the inlet and the outlet. The microfluidic channel may move the sample toward the outlet by capillary action. In the fluidic channel substrate, a plurality of capture parts, respectively corresponding to the RF resonance structures, may be formed along the microfluidic channel and may selectively capture the microplastic by particle size. The RF resonance structures may output information about the microplastic captured in the corresponding capture part through RF resonance for the applied RF signal.

Abstract: There is provided a temperature data-based gas usage correction method for a gas data platform. According to an embodiment, an energy usage correction method may collect gas meter reading data, may calculate energy usage based on the gas meter reading data, may collect temperature data, and may correcting the calculated energy usage. Accordingly, when it is impossible to obtain temperature in reading a gas meter, temperature compensation may be performed by linking temperature data collected separately and gas usage, and gas usage may be more exactly measured by correcting gas usage by compensating for temperature variation caused by a difference in seasons, installation regions in a gas data platform.

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.
