Related to the situation on the Korean Peninsula, by North Korea's threat of war the tension escalates and serious crisis continues. The purpose of this study is to evaluate the subjective perception which the residents of South Korea feel about North Korea's threat of war through a Q methodological analysis framework. In the result of the study, for the North Korea's threat of war the South Korean's recognition type is analyzed into four type such as 'non-reactive', 'fearreactive', 'psychological anxiety' and 'cynical ignorance type'. First, the No. 1 type 'non-reactive' does not empathize with North Korea's threat of war itself, and second type 'fear-reactive' have uneasy feeling like that 'What would happen as things go' and feel a sense of crisis about the North Korea's threat of war. The third type 'psychological anxiety' is type which feels that due to North Korea's threat of war inter-Korean relations is in the crisis. Finally the fourth type 'cynical ignorance' think that North Korea's threat of war is bluffing and also North Korea is like a shepherd boy. The reason to apply Q-methodology in this study is to make it possible to a more in-depth approach to subjective perception and threat of psychological meaning for the threatening message of study participants.

The Republic of Korean Navy (ROKN) started from scratch. However, ROKN demonstrated its Blue Navy capabilities successfully to the entire world by conducting "Operation Early Dawn" at the Aden Bay, Yemen in Jan 2011. On the event of the 70th anniversary of the ROKN, I would like to retrospect past gleaning from voyages and challenges we had in the past. At the very inception of the ROKN, Korean government as well as senior military leaders recognized that it had no time to spare to clean up military those were insinuated deeply by communist agents. It was the top priority of the government. The Mongumpo Operation which was not well known, conducted by ROKN was one of the clean-up drive. The Korean War sometimes called as "a fire from land put-off at the sea". The world famous "Incheon Landing" which reversed war situation from the Nakdong Perimeter also done by Sea Power. ROKN conducted various maritime operations including not only Incheon Landing, but amphibious operation at Hungnam, mine sweeping, sea convoy, Wonsan Withdrawal. On the same day of the Korean War started, 25th June 1950, unless the victory of the ROKNS Baekdusan (PC 701) at the Korean Strait, the waning lamp light of Korea could not be rekindled by the participation of the U.N. The ROKN rescued the 17th regiment of Korean Army from the isolation at the Ongjin Peninsular and transported gold and silver bars stored at the Bank of Korea to the Navy supply deposit in Jinhae safely. ROKN special intelligence unit conducted critical HUMINT which led Incheon Landing success. One of important mission ROKN conducted successfully was not only transporting war fighting materials but also U.S. provided grains to starving Koreans. ROKN participated Vietnam campaign from 1960s and conducted numerous maritime transportation operations supplying materials to Vietnam military forces along the long coastal lines. Experienced Naval Officers and enlisted men who discharged and acquired as merchant marine certificate supported most of the U.S. sea lift operations throughout the Vietnam campaign. ROK-US Combined Forces which had been honed and improved its war fighting capabilities through the Korean War and out of Vietnam jungle playing key deterrent against threat from north Korea. However, those threat level will be completely different when north Korea finish its nuclear weapon ambition. In order to stand firm against north Korean nuclear threat, I would like to expect strong political leadership supporting nuclear submarine for ROKN.

After successful nuclear tests Pakistan launched a more severe surprise attack toward India than before. It is highly possible that North Korea will adopt this Pakistan military strategy if it is armed with nuclear weapons. The North Korean forces armed, with nuclear bombs could make double its war capability through strengthening aggressive force structure and come into effect on blocking reinforcement of the US forces at the initial phase of war time. Therefore we may regard that Pyongyang's nuclear arming is a major one of various factors which increase possibility of waging a conventional warfare or a nuclear war. North Korea's high self-confidence after nuclear arming will heighten tension on the Korean Peninsula via aggressive military threat or terror toward South Korea, and endeavor to accomplish its political purpose via low-intensity conflicts. For instance, nuclear arming of the Pyongyang regime enforces the North Korean forces to invade the Northern Limit Line(NLL), provoke naval battles at the West Sea, and occupy one or two among the Five Islands at the West Sea. In that case, the South Korean forces will be faced with a serious dilemma. In order to recapture the islands, Seoul should be ready for escalating a war. However it is hard to imagine that South Korea fights with North Korea armed with nuclear weapons. This paper concludes that the Pyongyang regime after nuclear arming strongly tends to occupy superiority of military strategy and wage military provocations on the Korean Peninsula.

Threat Evaluation(TE) which has air intelligence attained by identifying friend or foe evaluates the target's threat degree, so it provides information to Weapon Assignment(WA) step. Most of TE data are passed by sensor measured values, but existing techniques(fuzzy, bayesian network, and so on) have many weaknesses that erroneous linkages and missing data may fall into confusion in decision making. Therefore we need to efficient Threat Evaluation system that can refine various sensor data's linkages and calculate reliable threat values under unpredictable war situations. In this paper, we suggest new threat evaluation system based on information fusion JDL model, and it is principle that combine fuzzy which is favorable to refine ambiguous relationships with bayesian network useful to inference battled situation having insufficient evidence and to use learning algorithm. Finally, the system's performance by getting threat evaluation on an air defense scenario is presented.

The South Korean ethnic diaspora US lobby shows efficacy as an interest group in generating influence in American foreign and domestic public policy making. The persuasive portrayal of South Korea as a critical Cold War US ally reinforced US amenability to pro-South Korea lobbying. Also, the South Korean US diaspora is a comparatively recent immigrant group, thus its lingering resistance to assimilation facilitates its political mobilization to lobby the US government. One source of this influence includes the foundational legacy of proselytizing Western and particularly American religious social movement representatives in Korean religiosity and society. US protestant Christianity acquired a strong public association with emerging Korean nationalism in response to Japanese imperialism and occupation. Hostility towards Japanese colonialism followed by the threat from Soviet-sponsored, North Korean Communism meant Christianity did not readily become a cultural symbol of excessive external, US interference in South Korean society by South Korean public opinion. The post-Cold War shift in US foreign policy towards targeting so-called rogue state vestiges of the Cold War including North Korea enhanced further South Korea's influence in Washington. Due to essential differences in the perceived historical role of American influence, extrapolation of the South Korean development model is problematic. US hegemony in South Korea indicates that perceived alliance with national self-determination constitutes the core of soft power appeal. Civilizational appeal per se in the form of religious beliefs are not critically significant in promoting American polity influence in target polities in South Korea or, comparatively, in the Middle East. The United States is a perceived opponent of pan-Arab nationalism which has trended towards populist Islamic religious symbolism with the failure of secular nationalism. The pronounced component of evangelical Christianity in American core community nationalism which the Trump campaign exploited is a reflection of this orientation in the US.

The key lessons of the very complex modern war can be dangerously misleading to the outsiders. The efforts trying to draw lessons learned from the Iraq War (OIF : Operation Iraqi Freedom) may be biased by the view of point by Americans, because most of war episodes have been come from the Western media coverage. More serious bias can be committed thanks to the differences of warfighting doctrines and military technology between US forces and ROK forces. However, OIF-fought allied commanders and outside military experts said this campaign exemplified 21st-century warfare: swift, agile and decisive, employing overpowering technology to bring relentless violence to bear in many places at once. Even though the campaign evolved differently than anticipated, allied forces regrouped and regained the initiative remarkably quickly, thanks in large part to a new command flexibility, tied to new technology that made possible the more rapid sharing of data. These factors permitted "new air-land dynamic". The things that compel that are good sensors networked with good intelligence disseminated through a robust networking system, which then yields speed. Speed turns out to be a very important factor for conducting "Rapid Decisive Operations" relied on joint "Mass of Effects". ROK forces facing the heaviest ground threat in the world may learn more from Cold War era-typed US Army 3rd Infantry Division (3ID), which operating considerably beyond existing doctrine. 3ID flew its personnel into Kuwait to meet up with equipment already located in the region as pre-positioned stock. During OIF, the division conducted continuous offensive operations over 230km deep battlespace for 21 days. The lessons learned for ROK army to prepare tomorrow's war may be found from 3ID in its training, command and control, task organization, firepower and battlespace management, and logistics.

As many of armored vehicles are seriously exposed to threat of IEDs(Improvised Explosive Devices) in the Afghanistan war and the Iraq war. V-shaped military vehicles are deeply studied in order to protect crews and mounted soldiers against land mines. Generally the experiment on full-scaled V-shaped structure needs excessively high cost, which becomes a huge barrier to study. In this paper, we explore the possibility to make a half-scaled model of the V-shaped structure by using the geometric similarity scaling. We demonstrate the geometric similarity scaling between the original model and the half-scaled model is established on the momentum and deflections of structure via computer simulations and experiments. At this stage, we conduct only numerical analysis of predicting vibration of V-shaped structure because measuring vibration of structure is difficult in the mass-explosion experiment, which is remained as future work.

In this article, Russia's space threat assessment and space warfare in the Russia-Ukraine war (Russian invasion of Ukraine) were analyzed and summarized. Considering the probability that commercial satellites will also be potential targets of space warfare, it is suggested that not only military satellites but also commercial satellites develop and apply space technology that can be applied equally to space threats when developing space technology. Necessary space technologies is listed.

This article is a sub-section of a comparative analysis of depictions of violence in Jakarta's Museum of the Indonesian Communist Party's Treachery, Ho Chi Minh City's War Remnants Museum, and Phnom Penh's Tuol Sleng Genocide Museum. In comparing these public history sites, I analyze how memories of mass violence were central to state formation in both Suharto's anti-Communist New Order (1966-1998), the Socialist Republic of Vietnam (1976-present), and Cambodia since the collapse of Democratic Kampuchea (1979-present). While this comparison points out specific distinctions about the role of the military, the nature of revolution, and conceptions of gender, it argues for a central similarity in the use of a mythology of victimization in building these post-conflict nation-states. This article focuses on my gendered analysis of the use of images of women and children in each museum. Depending on context and political purpose, these museums cast women as tragic victim, revolutionary heroine, or threat to the social order. My analysis of gender places stereotypical images of violence against women (the trope of women and children as the ultimate victims) in conversation with dark fantasies of women as perpetrators of savage violence and heroic images of women liberated by participation in violence.

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.
