The purpose of this study is to find out the change of statistical characteristics of typhoons affecting the Korean Peninsula. For this purpose, we analyzed the occurrence frequency of typhoon for 50 years (1954-2003) and change of air temperature and sea surface temperature near the Korean Peninsula in the same period. We classified typhoon tracks affecting the Korean Peninsula, and analyzed their trends and the amount of damage by typhoon. While the annual occurrence frequency of typhoon in the western North Pacific gradually decreased, its frequency affecting the Korean Peninsula increased. In addition, the occurrence location migrated northward. This coincides with the increase in air temperature and sea surface temperature around the Korean Peninsula. Typhoon tracks affecting the Korean Peninsula were classified into 7 types. Among them, the occurrence frequency of type 6 and 7 has increased. Although the occurrence frequency is low in type 2, the amount of damage by typhoon and occurrence frequency are increasing recently.

The representative Cretaceous-Tertiary paleomagnetic poles of the Korean Peninsula have been obtained from primary remanences of unremagnetized rocks: $59.6^{\circ}N$, $194.7^{\circ}E$ for $K_{1M}$; $67.6^{\circ}N$, $207.7^{\circ}E$ for $K_{1L}$; $71.1^{\circ}N$, $215.2^{\circ}E$ for $K_2$; and $84.9^{\circ}N$, $292.6^{\circ}E$ for the Miocene. Chemical remanences of remagnetized rocks also yield Early Tertiary paleomagnetic pole ($83.9^{\circ}N$, $88.3^{\circ}E$). These paleopoles provide the tentative APWP of the Korean Peninsula since the Cretaceous, and suggest some tectonic interpretations as follows. The Korean Peninsula was located at similar latitude to the present position, and rotated clockwise with respect to the adjacent blocks during the Cretaceous. The Korean Peninsula experienced latitudinal movement during the Early Tertiary, which was possibly associated with the continental collision between India and Asia. The Korean Peninsula and Southwest Japan might be independent terrains during the Cretaceous based on the temporal discrepancies of the southward movements and the clockwise rotations of the two blocks with respect to Eurasia.

The Korean Peninsula has the gateway role of Far East Asia in economic aspect, because it is the channel to global world that Korea and Japan should take in the future. Till now, there was no real economic cooperation in service industry for two Koreas. Nevertheless, it is high time that two Koreas have to play a gateway role in order to pave the way to come true their global vision. This paper aims to examine the possibility of economic cooperation between two Koreas in service sector and explore the vision and strategy which are useful for the ways toward peaceful unification on the Korean Peninsula and two Koreas' future survival in the midst of global competition. Economic cooperation in service sector, such as transport, tourism, educational services, etc. between two Koreas means establishing and strengthening the infrastructure of their unification. If there were no cooperation of service sector on the Korean Peninsula, we also could not expect the outcome of economic cooperation and the vision of Korea's unification. To sum up, the strategy recommended for the Korean Peninsula's global vision is that two Koreas should simultaneously open the window of economic cooperation in service sector and link the interface between the Eurasian continent and the Korean Peninsula.

It is known through prior research that the crust of the Korean Peninsula moves southeast at an annual average of 3 cm/year. The 2011 Great East Japan Earthquake caused a great change in the crust of the Korean Peninsula. Since then, the frequency of earthquakes has increased on the Korean Peninsula. Therefore, by using NGII and IGS GNSS observation data of the recent 15 years, to analyze the trends of changes in the deformation of the Korean Peninsula before and after the outbreak of the Great East Japan Earthquake. Data processing utilized Bernese Software V5.2, a widely used scientific and technical software around the world. As a result, the global movement of the Korean peninsula differed by about 4mm and the direction of movement by about 10° compared to before the Great East Japan Earthquake. As for the internal distortion of the Korean Peninsula, the East-West expansion of the Korean peninsula's crust was observed during the Great East Japan Earthquake, but it is believed that it has not fully returned to the level before the Great East Japan Earthquake.

The unity of korean peninsula have traditionally been established as major policy in korea government. Present government also set Trust Process on the Korean Peninsula as national high-level strategies for unity, and construction field related directly to living of north korean as major industry which would be implemented in early stage. Deterioration level of architectural facilities in north korea is known as very high, so a huge budget would be required to improve aging architectural facilities for stability of social and living of north korean. Therefore the purpose of this study deduct financing plan for improving aging architectural facilities in north korea and selection of optimal alternative securing effectiveness. The results of this study could be utilized as preliminary data for establishment of master plan and policy for improving deteriorated facilities in situation of united korean peninsula.
