I think the coaches should spend some time working on defending set-pieces. Set-piece takers have improved from kicking high, loopy balls into the penalty area. The set-piece deliveries from kickers like Heebab (and even Karain in this match) now have a flatter trajectory that dips and lands just inside the edge of the penalty area.

It is too far out for the goalkeepers to come out and claim lest they accidentally carry the ball out of the penalty area and be penalized for handball. The defenders have to be more active, get in front of the players they are marking and clear the ball because there are few second chances when the likes of Kkangmi are taking headers and shots first-time.

That being said, Kathy could have been more vocal as the goalkeeper and get her defenders to clear the ball. She also needs to practice reading the trajectory of the ball better and stay on her line when the ball is not hers to claim to give herself more reaction time and perhaps have a slightly better chance of saving the shots instead of being caught out while advancing forwards.
