Abstract: A message service providing apparatus according to an embodiment of the present invention includes: a message interface processor for providing a message interface to a user terminal, processing a message transmitted and received through the message interface, and providing one or more opinion expression items that can be included in the message to the user terminal through the message interface; and an active object database management processor for performing an active object database management process for each opinion expression item to provide one or more opinion expression items and opinion expression sub-items corresponding to the opinion expression items.

Abstract: Provided are a separator coating composition for a secondary battery including inorganic particles and a silane salt compound having a specific structure, a separator using the same, and an electrochemical device including the same. Specifically, a separator coating composition for a secondary battery which implements adhesion between an inorganic material layer and a porous substrate without including an acid/polymer-based organic binder in a coating composition for forming the inorganic material layer on one or both surfaces of the porous substrate and does not need a separate dispersing agent for dispersing the inorganic particles, a separator manufactured using the same, and an electrochemical device including the separator are provided.

Abstract: There are provided a semiconductor device and a manufacturing method thereof. The semiconductor device includes: a stack structure including a plurality of interlayer insulating layers and a plurality of gate conductive layers, which are stacked in an alternating manner; at least one support structure penetrating the stack structure in a substantially vertical manner, the at least one support structure being formed in a contact region; and a contact plug penetrating the stack structure in a substantially vertical manner, the contact plug being formed in the contact region, the contact plug being connected to a contact pad that is disposed on the bottom of the stack structure. The at least one support structure is formed of an oxide layer.

Abstract: A chat service providing apparatus may include a message analyzer and an artificial intelligence processor. The message analyzer may identify a first expression item included in at least one chat message received from a user terminal, analyze an attribute allocated to the first expression item on the basis of an analysis medium frame, and determine a user's intention according to a result of analyzing the attribute. The artificial intelligence processor may recommend a second expression item from among a plurality of registered expression items on the basis of a conversion condition which is an algorithm for selecting an expression item having an attribute corresponding to the user's intention among the plurality of expression items. The analysis medium frame may include, as an attribute, at least one of a description of an expression item, a reference emoji, a representative intension, and a representative language.

Abstract: A message service providing apparatus includes: a message interface unit for providing a message interface to a user terminal, processing a message transmitted and received through the message interface, and providing one or more expression items that can be included in the message to the user terminal through the message interface; and an active object database management unit for performing an active object database management process of each expression item to provide one or more expression items through an extended reality interface.
