Abstract: A battery module has improved waterproof and anti-vibration performance and a battery pack including the same. The battery module may be configured such that a battery cell is received in a space defined by a lower case and an upper case. A lower rib at a tip end of the lower case and an upper rib at a tip end of the upper case are brought into contact with each other, and the contact includes one face contact and one or more line contacts.

Abstract: An integrated circuit (IC) device includes: a fin-type active area protruding from a substrate and extending in a first horizontal direction; a first nanosheet disposed above an upper surface of the fin-type active area with a first separation space therebetween; a second nanosheet disposed above the first nanosheet with a second separation space therebetween; a gate line extending on the substrate in a second horizontal direction intersecting the first horizontal direction, at least a portion of the gate line being disposed in the second separation space; and a bottom insulation structure disposed in the first separation space.

Abstract: The present disclosure relates to a machine learning method and apparatus using steps feature selection based on a genetic algorithm, and the machine learning method includes defining a feature set including a plurality of features, generating a plurality of feature combinations including n-dimensional features (n is a natural number) for the feature set, independently constructing feature models for the plurality of feature combinations and calculating prediction accuracy for each of the feature models as a prediction result for a predetermined data set, arranging the feature models according to the prediction accuracy to determine at least one good feature model that satisfies a preset criterion, determining at least one good feature from among features included in a corresponding feature set of the at least one good feature model, and updating the feature set to include only the at least one good feature and re-determining a good feature model for a (n+1)-dimensional feature combination based on the update

Abstract: There is provided a method for determining dementia risk factors by a server using deep learning. In this instance, the method for determining dementia risk factors includes acquiring biometric information from each subject corresponding to a first control group through a wearable device, acquiring measurement information for each subject corresponding to the first control group, deriving a first dementia risk factor based on the biometric information and the measurement information for each subject, and deriving a second dementia risk factor related to the first dementia risk factor via deep learning performed based on the biometric information related to the first dementia risk factor and control group information.
