Abstract: Provided are carbon dioxide capture composite particles which contribute to carbon neutrality by fixing carbon dioxide in seawater or an aqueous solution in which calcium ions are dissolved through mineralization, and a method of producing the same. More particularly, provided are carbon dioxide capture composite particles which capture carbon dioxide in seawater to form calcium carbonate particles, preferably aragonite type calcium carbonate, and a method of producing the same. In an exemplary embodiment, a method of producing carbon dioxide capture composite particles including: immersing polyamidoamine particles in seawater or an aqueous solution in which calcium ions are dissolved and maintaining the solution at room temperature under normal pressure to produce carbon dioxide capture composite particles in which aragonite type calcium carbonate particles are formed on a surface of the polyamidoamine particles is provided.

Abstract: An automated gas supply system includes a gas cylinder transfer unit configured to transfer a cradle in which one or more gas cylinders storing a gas therein are stored; a gas cylinder inspection unit configured to check properties of the gas stored in the gas cylinder transferred from the gas cylinder transfer unit and check whether the gas leaks from the gas cylinder; a storage queue configured to receive the gas cylinder from the gas cylinder inspection unit by a mobile robot and configured to classify and store the transferred gas cylinders according to the properties of the gas stored in the gas cylinder; and a gas cabinet configured to receive the gas cylinder from the storage queue by the mobile robot and fasten a gas pipe, which is connected to a semiconductor manufacturing process line, to a gas spray nozzle, which is disposed at one side of the received gas cylinder, to supply the gas stored in the gas cylinder to the semiconductor manufacturing process line, wherein the gas cabinet includes a resid

Abstract: A mold-concrete composite crossbeam includes a H-steel composed of upper and lower flanges and a web connecting them; a concrete member formed in a length direction of the H-steel to expose the upper flange out but bury the lower flange and the web partially; deck plate supports installed to both upper side edges of the concrete member to support a deck plate placed thereon; a reinforcing steel bar installed around the H-steel; a mold including a bottom detachably coupled to a lower end surface of the concrete member, and sidewalls formed in parallel to both sides of the bottom and detachably coupled to both end sides of the concrete member; a lateral reinforcing member coupled across both sidewalls; a side reinforcing member installed to an outer side of the sidewalls in a length direction; and bottom reinforcing members installed across a lower surface of the bottom.

Abstract: The present invention relates to a system and method for automatically accessing a corresponding Internet web page by inputting a code recorded on a printed medium without inputting a uniform resource locator (URL) or performing hyperlink operation in a web browser. In an automatic Internet access system according to the present invention, instead of simply forming an Internet access node using the URL of a web page to be accessed, the Internet access code is formed using index information, double code information containing a server code and an index code, or hierarchical code information containing a service code and a detailed code.
