2015 is evaluated historically a very important time for both North and South Korea since the 70th year of division. Especially, in respect of North Korea, 2015 is the first year for Kim Jong Un, the chairman of the National Defense Committee to show his own politics in earnest, finishing ruling with dying instruction 3 years after his father, Jong-il Kim, died. Kim Jong Un directly announced ‘New Year’s Address of trying Standing-alone,’ selecting his grandfather, Kim Il Sung’s style rather than his farther, Jong-il Kim’s reclusive style. What he put the most emphasis on in the New Year’s Address was ‘Piercing Wind of Baedusan’ and ‘Revolutionary Spirit of Baedu.’ Renewedly, he pointed out that 5 kinds of culture ‘greatness culture’, Kim Jong-il patriotism culture, faith culture, anti-class culture, ethics culture’ should be intensified. In the New Year’s Address, Kim Jong Un suggested ‘Piercing Wind of Baekdusan’ as a big slogan and emphasized ‘Cutting Edge of Breakthrough’ as a small slogan while presenting blueprints of national defense arms and economy and putting an emphasis on scientific technology. After analyzing novels announced by 『Joseon Literature』 or 『Literature Paper』 in 2015, it was confirmed that creation of ‘Joseon Speed’, realization of politics of ‘Respect for People ․ Love for People’ by increasing production, and construction of ‘a fairyland of happy socialism’ of future vision to construct a strong country as a practical plan. The first practical task has a meaning of promotion of developing nuclear missiles, launching satellite rockets, and building submarines and asymmetric weapon system for ‘self-protection from foreign power.’ The second practical task is considered as a practical discourse of real politics to realize ‘prosperity through creation’ by securing people- friendly leadership. Finally, the third practical task is regarded as a presentation of the vision of a dream to solve the problem of ‘people’s welfare’, which means the minimum living standard guarantee and health promotion by finding an approach on the level of social welfare and to realized a fairyland of happy socialism’ within his regime by solving social problems, like ‘forest recovery, restoration of ecology.’ However, as for practical discourses suggested by Kim Jong Un, the first one has a limitation in that it is a behavior to cause criticism of international society and international isolation from the world, including UN. The second one shows a limitation that North Korea will repeat stagnation due to the standstill of economic growth without an influx of foreign capital and technology. The third one causes the concern that ‘People’s living from hand to mouth’ should be solved first instead of ‘welfare’ in the future. As a measure to break through these realistic limitations of various practice discourses, the realization of Kim Jong Un’s style gestures to suggest the improvement of relationship between South and North Korea and the possibility of inter-Korean summit is worthy of attention.
