Abstract: According to an embodiment, an on device-based system for suppressing the leakage of personal information and for providing personalized response includes: a plurality of user devices configured to detect Personal Identifiable Information (PII) from a user query and transmit a user-neutral query which is obtained by converting the PII into neutral information; and a management server configured to receive the user-neutral query and train a management language model that generates a common response pattern for each neutral query pattern.

Abstract: Multimodal polyolefin resins for manufacturing films, pipes, hollow molded articles having high melt strength and excellent formability, mechanical strength, processability and appearance are described. The resins have: density is 0.930-0.960 g/cm3; melt flow index is 0.01-10.0 g/10 minutes; ratio Mw/Mn is 10-60; and two or more peaks appear when molecular weight is measured by GPC. In molded pipe, the Mw of polymer collected at position B is 0.1% greater than Mw of polymer collected at position A; polymer having Mw of 10,000 or less among polymers collected at position A is 0.1% greater than the amount of polymer having Mw of 10,000 or less among polymers collected at position B; and the amount of polymer having Mw of 1,000,000 or more among polymers collected at position B is 0.1% greater than the amount of polymer having Mw of 1,000,000 or more among polymers collected at position A.
