Park Geun-hye, President of South Korea, takes an oath during her inauguration ceremony.
SEOUL, South Korea (AP) -- Park Geun-hye has become South Korea's first female president and returned to the presidential mansion where she grew up with her dictator father.
As president, Park will face stark divisions both in South Korean society and with rival North Korea, which detonated an underground nuclear device about two weeks ago. South Koreans worry about a growing gap between rich and poor, and there's pressure for her to live up to her campaign suggestion that she can return the country to the strong economic growth her strong-man father oversaw.
Park technically took over as the clock struck midnight. Her swearing-in ceremony Monday was to be attended by tens of thousands, including international dignitaries.
