Abstract: A method and system for training an image classification model is disclosed. An aspect is to separate training processes of a feature value extraction model and an image classification model and train the feature value extraction model on a representative feature value suitable for image classification into a specific label value (e.g., “Peak”), thereby improving accuracy and performance of a classification model for a ground-penetrating radar (GPR) image that is captured by a GPR and is not easy for feature value extraction.

Abstract: A composite pin fin heat sink configured to dissipate heat generated by a heating element including a background region and a hot spot region having a higher temperature than the background region while the heating element is generating heat, the heat sink including a base plate having a first surface and a second surface, the first surface being configured to contact the heating element; and an array of pin fins protruding from the second surface and arranged at regular intervals. The base plate and the array of pin fins are divided into a first heat sink region corresponding to the hot spot region of the heating element, and a second heat sink region corresponding to the background region of the heating element. The first heat sink region is made of a material having a higher thermal conductivity than a material of which the second heat sink region is made.

Abstract: Disclosed are a hollow mesoporous organic silica nano/microparticle having metal particles deposited thereon, and a method for preparing the same of the present disclosure. The method may prepare a spherical nanoparticle by coating a porous organic silica layer on an inorganic silica particle having the metal particles deposited thereon and via selective etching of the layer. In addition, two or more types of metals pre-synthesized together with a magnetic particle, or different shapes of metals may be deposited on the nanoparticle at a target concentration. Thus, the nano/microparticle may be used for a drug delivery matrix, a catalyst, and a photothermal effect.

Abstract: Disclosed are a method and apparatus for predicting a change in the occupants within a large exhibition hall in real time based on deep learning. A proposed method of predicting a change in the number of occupants within a space in real time includes dividing, into zones, a space where a number of occupants is to be predicted and pre-processing data related to a number of occupants within the space collected through simulations, generating the pre-processed data in a form of time-series data for deep learning, training a deep learning model for predicting a number of occupants in each divided zone using the generated time-series data, and predicting the number of occupants within the space by inputting, to the trained model, the data related to a number of occupants within the space collected in real time through socket communication with a server.
