Domestically, Due to the reign of King Sejong operating, stable operation of the country was able to achieve. However, at that time it is a fact that was beating due to the unstable northern state of affairs. The mid-15th century, the Ming dynasty was shaken due to the strengthening of the forces of the Northern Mongolia. As a result,the Chosun dynasty and Yeojin(女眞), Japan was a time when too greatly disturbed. ‘The event of Tomok(土木)’ occurred in the last years of King Sejong’s life, especially Chosun’s administrator was a big shock. This will be the biggest threat to Yang Seong-Ji who was budding bureaucracy. By the traumatic event of Tomok(土木), Chosun dynasty required a new national defense measures. In this study, we explained how did Yang Seong-Ji recognize about the situation in the northern mid-15th century, and any measures to prepare for these threats envisioned, and what specific information he presented Gwanbang-theory(關防論) and ultimately through Yang Seong-Ji who was represented by defense and homeland of the core ideas about what it looked. Yang Seong-Ji's Gwanbang(關防) ideas of contemporary international affairs is not simply academic insights through the defensive, and his geographical, historical insights this comprehensive product is shown that the results can be. He suggested Yoeup Gwanbang-theory(要邑關防論) mere defense theory, rather than to understand the level of the national defense strategy. In addition to focusing on traditional security concept phase for us today who are facing the threat of North Korea, but to diversify the international situation in the delivers based largely sober insight and view on the necessity of establishing a national strategy for the contemporary implications.
