  • In this study, we identified characteristics of heatwaves on the Korean Peninsula and related atmospheric circulation patterns using data on the daily maximum temperature (TMX) and reanalysis data for the past 42 years (1979-2020) and analyzed their connection to the Arctic oscillation (AO). The heatwave on the Korean Peninsula showed to be stronger and more frequent in the 2000s. The recent strong and frequent heatwaves on the Korean Peninsula are mainly affected by abnormal high-pressure over the Korean Peninsula on the middle/upper-level atmosphere and the strengthening of the North Pacific high pressure. Interestingly, composite difference of sea level pressure showed very similar results to the positive AO pattern. The correlation coefficients between the summertime AO and the TMX and HWD of the Korean Peninsula were 0.407 and 0.437, respectively, which showed a statistical significance in 1%, and showed a clear relationship with the abnormal high-pressure over the Korean Peninsula and the strengthening of the North Pacific high pressure. In addition, in the positive AO phase, the TMX and HWD of the Korean peninsula were approximately 30.1 ℃ and 14.6 days, which were about 1.2 ℃ and 8.8 days higher than in the negative AO phase, respectively. As a result of the 15-year moving average correlation analysis, the relationship between the heatwave and AO on the Korean Peninsula has increased significantly since 2003, and the linear relationship between them has become more apparent. Moreover, after the 2000s, when the relationship developed, AO had more strongly induced the atmospheric circulation pattern to be more favorable to the occurrence of heatwaves in the Korean Peninsula. This study implies that understanding the AO, which is the large-scale variability in the Northern Hemisphere, and the Arctic-mid latitude teleconnection, can improve the performance of global climate models and help predict the seasonality of the summer heatwave on the Korean Peninsula.

  • The situation in Korean peninsula, globally and regionally, which followed the global huge uncertainty, changed a lot. Because of the political crisis, ROK falls into a chaos. And DPRK goes into a policy changing period by the internal issues, international sanctions and assassination accident in Malaysia, which is confirmed to be DPRK's Supreme leader, Kim Jong Un's half brother. Under this changing circumstances, the perspectives of regarding China and the Korean peninsula, must be undated accordingly. Only by understanding the Sino-US relations, the DPRK nuclear issue and the regional dilemmas can we formulate reasonable policies to contribute to the peace and stability of the Korean Peninsula.

  • The Korean peninsula has diverse habitats and so would be expected to have a rich millipede fauna because of its location between the Paleoarctic and Oriental regions. To facilitate studies on millipedes, this work provides an updated list and discussion of Korean millipedes. A total of 69 species had been recorded up to 2010, but since then no new species have been reported. Among 69 species, 49 are endemic to the Korean peninsula. From 1950 to the present, an average of only seven new species from the Korean peninsula has been described per decade. This number does not reflect the biodiversity of millipedes in Korea, especially when compared to Taiwan, which has only one-third the area of the Korean peninsula, but from which a greater number of millipede species have been recorded (75 vs. 69 species). Japan has twofold the land area of the Korean peninsula, and an almost threefold higher number of millipede species. Further, more-intensive surveys will likely result in identification of more millipede species in the Korean peninsula.

  • To investigate the frequency and trajectories of volcanic ash from Mt. Baekdu reaching the Korean Peninsula, a forward trajectory analysis was conducted using the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model. Through a cluster analysis of air parcel trajectories, we identified the main pathways of the volcanic ash from Mt. Baekdu entering the Korean Peninsula and analyzed the synoptic meteorological conditions on those days. The frequency of volcanic ash reaching the Korean Peninsula was 82 times at an altitude of 1000 m and 70 times at 2000 m, with an increasing trend from 2016 to 2022. This increase is attributed to the weakening of westerly winds and the strengthening of north-south winds due to global warming. Five and three trajectory clusters were classified at 1000 m and 2000 m, respectively. At a starting altitude of 1000 m, most air parcels originating from Mt. Baekdu entered the Korean Peninsula under weather conditions (C2, C3) where the pressure gradient from the northwest to the southeast was small, resulting in weak northerly winds. C2 and C3 showed shorter trajectories, which occurred in all seasons, except summer. At a starting altitude of 2000 m, air parcels mostly passed over the Korean Peninsula in a synoptic pattern similar to that at 1000 m in altitude; however, the air parcels had simpler paths and less frequent inflow. C2, at a starting altitude of 2000 m, originates from Mount Baekdu, crosses the center of the Korean Peninsula, and continues to the central region. At a starting altitude of 1000 m, volcanic ash can enter the Korean Peninsula when there is no strong low-pressure system to the southeast of the Korean Peninsula, whereas at 2000 m, volcanic ash can enter the Korean Peninsula when the Siberian high-pressure system is weak.

  • This study is for the characteristic of expression of exhibition presentation in 'The Korean peninsula' which is the Golden Lion Winner at the Venice Biennale in 2014. The Korean peninsula provides two opposite political and economic systems and adaptations of modernism through various multi media images. The curator, Minsuk Cho, presented cinema montage image of Collision for analyzing dynamic exhibition organization and provides the foundation of his theory from Bergson's image and duration to Deleuze's movement-image and time-image which is mentioned from Deleuze's book "cinema 1" and "cinema 2". Furthermore, the Korean peninsula has showed perception-image and affection-image from Eisenstein & Vertov's cinemathology and systemized exhibition presentation. The montage of Collision has maximized the movement from the variety and complexity in a collision and it made difference between information images which are space, time, emotion, intelligence, the tumult between subjectivity and objectivity, fragments from reorganizing itself, and distribution and art images. The limit of montage of Collision's dialectic is not only visual but also space from organic organization but the Korean peninsula overcomes its limit and shows leap of tactile perception and time-reflection from the montage of Collision's dialectic. Therefore, the exhibition of the Korean peninsula presents the conviction of adaptations of modernism.

  • In order to study the disaster of typhoons which hit the Korean peninsula a period of 22 years from 1959 through 1980 was covered to collect necessary data with respect to attack of typhoons and their damage. Centering around the Korean peninsula, typhoons which attacked between 1959 and 1980 were grouped according to their treking routes and damage for detailed analyses. The results are summarized as follows: 1. The average annual damage of typhoons in the Korean peninsula was found to be 1.27 from June to September. The monthly distributions were found to be 53.6% in August, 28.6% in September and 14.2% in July. 2. About an half (56.4%) of the typhoons which hit the Korean peninsula passed through the western coast and 27.3% through the southern and 14.6% through the eastern. Typhoons of the we8tern coast were divided by their treking routes as 25.5% in CWE type (Jul., Aug., Sep.), 14.6% in WE type (Jul., Aug.), 16.3% in W type (Jul.). 3. The minimum SLP averaged 976.6mb and ordere:l by the treking routes as E$_1$$_1$ and CWE types are higher 20mb than S, E or WE types. 4. The Korean peninsula was damaged by all number of the typhoons in WE or S type, by a third at number of its in E or WE and WI type. 5. The annual probabilities of typhoon-disasters were 0.773 for once or more, 0. 409 for twice or more, and 0.091 for three times or more. Hearvy damage experienced in the Korean peninsula are found to have an annual. 6. Amount of the damage by the treking routes in ordered S>WE>CWE>E>W$_1$, and heavy storms experienced in the Xorean peninsula are found to have accompanied the WE and S types during the months of August and September. 7. The average annual damages were found to be 110 at the death-tall, 45, 000 at the sufferers and 10.5 billion at the property damage. 8. Seventy-sex percent of the all damage in the Korean peninsula distributed on the district from the 36th Parallel south and included Chie Ju island.

  • 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 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 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.
