  • As a multidisciplinary study encompassing oceanography and history, we have attempted to reanalyze the course of a historical navel battle, Myungryang Naval Battle(September 16th, 1597 according to the lunar calendar) through hindcasting the paleo-tidal currents and -tides(PTC). Firstly, we conducted harmonic analysis using 6-month current data observed at Uldolmok and 1-year elevation data provided by Korea Ocean Research and Development Institute in order to understand their characteristics and to hindcast the PTC. Observation results show that Uldolmok, ~300m wide, relatively narrow channel, is characterized by a flood-dominant mixed mainly semidiurnal tidal regime induced by relatively-strong shallow water constituents, showing closely a standing wave type of tidal current. Further, we hindcasted PTC on the day of Myungryang Naval Battle. Our results were compared and discussed with results(time and speeds of maximum(flood and ebb) currents and high and low water times) of the previous studies estimated from different methods. Lastly, we reconstruct the course of the event of Myungryang Naval Battle recorded in the Admiral Sun-Sin Yi's War Diary(Nangjung Iigi in Korean) based on our hindcasting results.

  • The negative symbol of 'American imperialism', which was reinterpreted superimposed on the symbol imposed on Japanese imperialism in the 1945 Liberation of Korea, was more amplified added by the experiences of the bombing and massacre by US troops during the Korean War. In other words, the symbol of the extreme 'American imperialism' in the liberation in which even the role of America contributing to the liberation of Josun had been denied had continued for a long time adhered to and amplified through the war. Thus, unlike the current emphasis laid by North Josun, the assertion in the form of 'American imperialism=Korean wolf' is an idea made from the mixture of fact and fiction combined with the theory of imperialism rediscovered in the liberation and the experience of massacre during the Korean War. And this superimposed symbol for American imperialism naturally causes the problem of being superimposed also on the symbol of North Josun. And the extreme formalization for 'good' and 'bad' sides was based on the dichotomous compositions of beauty and ugliness, good and evil. The ground for saying that an act by a good side is 'unconditionally' legitimate is nowhere found. The anti-American viewpoint rediscovered in such an extreme form results in one aspect of criticism and resemblance as a result of being locked up in the same violence which one has rejected by oneself. The anti-American viewpoint going on in the form of anti-imperialist nationalism leaves nothing except another terrible retaliation for terrible brutality. It is self-evident that one can never get out of the enchanting power of imperialism which North Josun has continuously criticized in a ring of violence and vengeance, the familiar grammar commanded by North Josun literature.

  • Before the Korean War, Korean mask dramas had been performed as parts of seasonal customs and had been passed down in connection with various seasonal events, such as village rites, tug of war, torch fighting, Jisinbabgi(stepping on evil spirits), Gilnori, and Sattonoreum. However, after the Korean War, the dramas were played independently regardless of those seasonal events; thus, they have lost their original functions and meanings. After the Korean War, the lion dance in the Bukcheong lion mask play included two lions (as opposed to one lion prior to the Korean War) and the Aeonesung and Sadang dances were added. The scene in which a lion eats a child changed to a lion eating a rabbit doll. Furthermore, whereas mask types used to be diverse, they are now standardized to one type of lion mask. In the Yangju Byulsandae-nori, eight monks and Waejangnye, Aesadang appeared in 'Aesadang Bubgonori', but now the Malddugi mask character is added. Current performances omit sexually suggestive scenes. In the pre-Korean War version of the old man and old woman act, the old man sang a song to the soul of the dead woman, but now a shaman appears and performs an exorcism. In the dialogues, vulgar and sexual statements have been shortened as many audience members are women and children. Regarding the appearance of the masks, the lotus leaf, the monk with Scabies, and sannim masks have been significantly changed. Bongsantalchum has also changed, especially in the old monk act. Previously, two Somu used to appear whereas now only one appears. The scene of the shoe seller's and the monkey's departure is also different. Furthermore, while the former masks once had big eye holes on each side of the nose, now the masks have smaller holes on the eyes.

  • This study compared and analyzed, after extracting the subject titles related to Korea and Japan from the second version of Chinese Classified Thesaurus, the number of titles and characteristics according to the subjects. The analysis result shows that total number of Korea-related titles including proper nouns was 215, which is limited in comparison to that of Japan, in terms of the number and diversity of the subjects. Particularly, the CCT does not accurately reflect the current state of Korea as it uses the word 'Josun' to denote Korea and calls Korean War 'Josun War' as well as only recording it in North Korean history. Meanwhile, Japan-related subject titles include many that show the complicated historical relationship between Japan and China, such as Manchurian Incident and Japan-China War.

  • Since June 25th 1950, the beginning of the cold war (Korean war), Korean peninsula is still in a state of war. Officially South and North Korean government call a truceafter three years from the beginning day, however both countries are still having several combats in these days. So every Korean citizen male has duty for serving military duty and this lasts even after the serving regular military force, as reserved military. Although South Korea is very small country, the size of military is very large so informing all reserved military takes some time. Since this nation is confronting the enemy and considering the global potential threat, South Korean military needs expedite informing system to call up the reserved military to active duty. In this project, the current informing system has been analyzed and compared with the new method which is using social network service such as Twitter. However mobilization order is very critical. So in our new model there are two ways combined. Using twitter to inform and then use traditional ways to finish the order. This method will provide more efficient and accurate way to cover the call ups.

  • The ROK Navy operates many war ships despite its short history. Various types of war ships, such as submarines, destroyers, frigates, corvette etc., use suitable propulsion systems for the operational requirements of each war ship. A hybrid propulsion system was introduced to change from the current mechanical propulsion system to an electric propulsion system according to the changing patterns of naval warfare, and it is expected that an integrated electric propulsion system will also be introduced. Therefore, this paper investigates the propulsion system of major ships operated by the Korean Navy, predicts the changes in future naval warfare, and proposes a propulsion system for future ships.

  • This article will analyze and forecast important variables and dynamics in global power politics after the war in Ukraine. It tries to use several perspectives to analyze international relations, particularly liberal internationalism and structural realism. In short, core variables are as follows; First, how is the US-led liberal international order and globalization being adjusted? Second, how will the U.S.-China strategic competition, which is the biggest and structural variable, cause changes in the international order in the future? The third variable, how stable are Sino-Russia relations in the context of a structuring U.S.-China-Russia strategic new triangle? Fourth, to what extent will third middle hedging states outside the U.S. and China be able to exercise strategic autonomy in the face of multipolarization? To summarize, the first of these four variables is the largest basic variable at the global political and economic level in terms of its impact on the international community, and it has been led by the United States. The second variable, in terms of actors, seems to be the most influential structural variable in global competition, and the US-China strategic competition is likely to be a long game. Thus the world will not be able to escape the influence of the competition between the two global powers. For South Korea, this second variable is probably the biggest external variable and dilemma. The third variable, the stability of Sino-Russia relations, determines balance of global power in the 21st century. The U.S.-China-Russia strategic new triangle, as seen in the current war in Ukraine, will operate as the greatest power variable in not only global power competition but also changes in the international order. Just as the U.S. is eager for a Sino-Russia fragmentation strategy, such as a Tito-style wedge policy to manage balance of power in the early years of the Cold War, it needs a reverse Kissinger strategy to reset the U.S.-Russia relationship, in order to push for a Sino-Russia splitting in the 21st century. But with the war in Ukraine, it seems that this fragmentation strategy has already been broken. In the context of Northeast Asia, whether or not the stability of Sino-Russia relations depends not only on the United States, but also on the Korean Peninsula. Finally, the fourth variable is a dependent variable that emerged as a result of the interaction of the above three variables, but simultaneously it remains to be seen that this variable is likely to act as the most dynamic and independent variable that can promote multilateralism, multipolarization, and pan-regionalism of the global international community in the future. Taking into account these four variables together, we can make an outlook on the change in the international order.

  • Russia invaded Ukraine in February 2022. Many military experts predicted that Russia could defeat Ukraine within a week, but the Ukraine-Russia War has not been going as expected. Indeed, Ukraine military has been defending well and seems to fight more efficiently than Russian military. There are many reasons for this unexpected situation and one apparent thing is due to artificial intelligence (AI) technologies. This study focused on AI-enabled combats that the Armed Forces of Ukraine has carried out around Siverskyi Donets River, the Crimean Peninsula, and suburbs of Kyiv. For more systematic analysis, the revolution in military affairs (RMA) theory was applied. There are four significant implications inferred by studying current Ukraine-Russia War. First, AI technologies are effective even in the current status and seems to be more influential. Second, hyper-connected network by satellite communications must be needed to enhance the AI weapon effects. Third, military AI technologies should be based on the civil-military cooperation to keep up with pace of technological innovation. Fourth, AI ethics in military should be seriously considered and established in the use of AI technologies. We expect that this study could help ROK Armed Forces to be modernized in the revolutionary fashion, especially for manned and unmanned teaming (MUM-T) system.

  • Two isolation methods using the open plate and air sampler were applied to examine microbial distribution as an environmental factor for conservation of cultural properties in the War Memorial in Korea. The numbers of fungi were the abundant in the air of entrance and inside of the exhibition room where visitors were crowded, compared with inside of repository rooms. Fungal and bacterial distributions in the exhibition room during exhibition period were higher than during nonexhibition period, These results are due to the inflow of air current carrying microoganisms to the exibition rooms from outside with visitors. Fungi isolated from the War Memorial were identified as 19 species and one thermophilic fungus, Neurospora crassa. The majority of the isolated fungi are seemed to cause damage to cellulose materials in the Memorial.
