North Korean leader Kim Jong Un inspected a Korean People's Army Air Force unit Jan. 30, his seventh inspection of a military unit this year. Kim has also attended three concerts, paid homage to his grandfather, Kim Il Sung, and father, Kim Jong Il, at the Kumsusan Memorial Palace, visited construction sites, toured a factory, visited Mangyongdae Revolutionary School, and watched a demonstration by a model aircraft club. Fifteen public appearances in one month is a fairly ambitious schedule for the new North Korean leader and particularly notable so soon after the death of his father. Kim Jong Il, upon the death of Kim Il Sung, observed a three-year mourning period while he consolidated power.
