We begin at the nation's top office from where President Park Geun-hye established a new position, that of a second deputy prime minister.
It came during a Cabinet meeting where the president outlined her newly-pledged government restructuring.
She said the prime minister would be in charge of law and order, public service reforms, and rooting out corruption.
While one of the two deputy prime ministers will maintain focus on the economy, the other, newly-established deputy will oversee matters related to education, society and culture, something the president says is critical in increasing efficiency and responsibility in policy-making.
Following Tuesday's Cabinet meeting, the presidential office said the nation's education minister would take on the new role.
