Abstract: The present invention provides an inverter and a bootstrap inverter with improved output characteristics. The inverter comprises a first and second load transistors, a driving transistor, and a control transistor. The control transistor, when turned on, effectively grounds the source of the first load transistor, ensuring a 0V output. The bootstrap inverter further includes a bootstrap transistor and a capacitor. This configuration solves the problems of output voltage being lower than VDD for logic ‘1’ and not completely 0V for logic ‘0’, achieving ideal output levels.

Abstract: A valuable alert screening method for detecting malicious threat includes generating an AI model based on training data for predicting test data, generating XAI explainability and selecting important features based on summary plot by using an explainer and training data, performing range processing based on data distribution of important features selected for analysis without bias, calculating a SHAP value average and standard deviation of each range group and then storing them to determine suspicion and reliability of test data, making prediction by using an AI model generated in advance after feature processing in the same way as the training data at the time of inputting the test data, calculating a SHAP value by using the test data and the explainer, loading FOS calculation information to calculate FOS for each important feature, and calculating a suspicion score for each data by aggregating the FOS after calculating the FOS for each feature.

Abstract: The present invention relates to a method and a system for recognition of objects near a ship by using a deep neural network to prevent a collision with the object by recognizing a neighboring object that may be risky to the ship sailing in a restricted condition such as a foggy environment. All object movements within a predetermined radius are detected and recognized so that collision accidents with objects on the sea in an environment such as fog caused by bad weather at sea can be prevented, and a risk alarm is notified to a captain when the object is detected so that collision accidents can be remarkably reduced. In addition, peripheral environments are detected by only installing a CCTV camera so that expenses can be reduced, human negligence can be prevented, and the system can be easily constructed to prevent collisions.

Abstract: A tag-based object location tracking system enables sharing the location of registered object tags with users within the same group. The tag-based object location tracking system can effectively provide a system that is capable of tracking the location of an object by attaching a tag to the object and sharing the location of the object with other users intended for sharing. The tag-based object location tracking system is advantageous in terms of preventing the loss of public items and managing location tracking in such a way as to locate the objects based on the location information acquired via a global positioning system (GPS) module, generate sound to help locate the object, and share the location of the tag with others.

Abstract: Disclosed is a system for advanced user authenticated key management for 6G-based industrial applications with respect to user authentication and management scheme to secure a 6G-enabled Network-In-a-Box (NIB). The system includes: a registration unit configured to perform registration of smart industrial device, content server, and user by using a trusted authority and an ID of the trusted authority; a user login unit configured to compute whether a Hamming distance between a biometric secret key provided to the registration unit and a currently recognized biometric secret key is equal to or less than a pre-defined error tolerance threshold; and a user authentication unit configured to perform mutual authentication among a pre-registered user Ux, a content server CSy, and an accessed smart industrial device SDz. Accordingly, a 6G-enabled Network-In-a-Box (NIB) can be secured.

Abstract: A search method using an artificial intelligence based information retrieval model and a method for training the artificial intelligence based information retrieval model used for the method are provided.
In the method, even if there is no labeled data and only a corpus exists, the artificial intelligence based information retrieval model can be trained using the weak-supervision methodology. Search can be performed by dividing documents into passages having short lengths. Compared to an information retrieval model based on unsupervised learning, improved search results are provided.-

Abstract: A CMOS inverter circuit includes a first and second PMOS transistor connected in series to a power supply voltage (VDD) and a first NMOS transistor connected in series with the second PMOS transistor and to ground (GND). All transistors receive the same input signal.
This configuration enables normal logic gate operation even when the P-channel characteristics of the PMOS transistors are shifted. The channel widths of the first and second PMOS transistors can be varied to adjust circuit performance.
