Irish athlete Thomas Barr has won the 400 metres hurdles gold medal at the World University Games in Korea while swimmer Fiona Doyle has picked up the silver in the women's 50m breaststroke.
Waterford man Barr, 22, ran one of the fastest times of his career as he took victory in 48.78 seconds in Gwangju.
That left him .24 of a second ahead of Algerian Abdelmalik Lahoulou.
Doyle, 23, won 100m breaststroke bronze at the Games on Sunday and picked up the 50m silver with a 31.09 clocking.
Ukrainian Mariia Liver took victory in 30.73 seconds with Limerick-born Doyle pipping Italian Martina Carraro (31.11) for the silver.
Hurdler Barr set a new Irish record of 48.90 last season and improved his national mark to 48.65 in Rome last month.
The Waterford man clocked 49.75 in his semi-final in South Korea on Thursday after a 49.96 heat win on Wednesday.
Algerian Lahoulou battled with Barr throughout Friday's final but the Irishman pulled clear after the final hurdle to take a comprehensive victory with Russia's Ivan Shablyuev third in 49.04.
Sonia O'Sullivan, Ronnie Delany and Niall Bruton are the only previous Irish track and field athletes to have won World University Games gold medals.
