Following those nominations, President Park is expected to shake up her Cabinet and presidential office aides before the week is out.
Pundits say the president is aiming to get the reshuffle out of the way before she travels to central Asia next week.
The major shake-up is part of her drive to reform government in the wake of the Sewol-ho ferry disaster.
The seats for the finance and education vice ministries are open while the foreign and unification ministers are pondered upon.
However as pundits expect at least 20 nominations are needed for President Park's reshuffling plans, some experts say it will take quite some time until the president's reform plans are complete.
