But the Koreans, who finished fifth at this year’s Winter Olympics, took four singles before the Scots managed a point on the board.
A three at the sixth end put Henderson’s rink back in contention, but that was to be their only score as the Koreans eased to victory.
The Scots, who take on the Canadians in their final Wednesday session, have also beaten Denmark and the United States but lost to China, Turkey, Switzerland and Sweden.
Henderson’s rink – Lisa Davie, Hailey Duff and Katie McMillan – are competing in their first world championships after their recent national championships win in Dumfries in the absence of Sophie Jackson’s rink who represented Great Britain at the Olympics.
The British rink had lost 9-3 to the same Korean rink in Cortina.
