KT said on Aug. 11 it has completed building an RCS (Rich Communication Services) messaging system for Lotte Department Store. RCS is a data-based messaging standard that supports high-resolution images and large video transfers and can be used in the default messaging app without installing a separate application. KT said the system is based on its enterprise messaging platform Communis, which integrates multiple channels including RCS, SMS, LMS, MMS and Kakao Alimtalk. The companies plan to expand cooperation on digital services.

Ecopro HN said on Sunday it signed a contract with Samsung E&A to supply a centralized greenhouse gas reduction system (RCS). The contract is worth 33 billion won, and the supplied equipment will be deployed at a South Korean semiconductor company. The firm said its RCS handles perfluorinated compounds from semiconductor processes using catalyst-based technology that decomposes PFCs at about 750 to 800 degrees Celsius.
