In the previous study, we associated 223 asteroids to 28 meteor showers by using three D-Criteria metrics, our own empirical method of threshold selection and D-parameter uncertainty. The databases used in the simulation were the MPCORB (for asteroids) and IAU Meteor Data Center (for meteor showers) from February 2017. In the present work, we will present an update of our previous study on the new databases (the MPCORB and meteor shower databases form February 2018). In the new simulation, we found 72 additional asteroids that can be associated to 20 meteor showers. By using physical parameters, we found the fast-rotator asteroid 2007RS146
