Wins above replacement (WAR) is the most commonly used statistics of the sabermetrics that measure baseball players' abilities. The advantage of a WAR is that it enables to compare performances of players even though they have different roles such as pitcher and hitter. However, WAR is difficult to obtain with common records. Thus, a past studies (Lee and Kim, 2016) suggested the batting ability index to determine the ability of the batter focused on the sabermetrics statistics WAR. In this paper, we selected the best hitter with applying Korea baseball 2016 data based on a proposed model and then observed a total raking of others according to BAI. We are assured that BAI is very excellent statistics through comparing BAI and WAR which is in the spotlight in evaluating performances of players.

Wins above replacement (WAR) is the most commonly used statistics of the many sabermetrics that measure baseball players' abilities. The advantage of a WAR is that it enables to compare performances of players even though they have different roles such as pitcher and hitter. However, WAR is difficult to obtain with common records. Thus, in this paper, we have calculated the sabermetrics variable based on Korean professional baseball records for the past three years (2014-2016). Using these variables, we suggest starting pitcher ability index that can replace WAR. Starting pitcher ability index was calculated by means of arithmetic mean, weighted average and principal component regression. Then, compared to the WAR, the most relevant method was selected, which would be useful to identify for the starting pitcher ability.

Wargame simulators are widely used in the field of defence modeling and simulation. Because of increasing importance of communication effects on the warfare, the war game simulator is also required to reflect communication effects. One way to satisfy the requirement is the interoperation simulation between war game simulator and communication effect simulators. This paper shows the application of interoperation simulation between war game and communication effect simulators using HLA(High-Level Architecture)/RTI(RunTime Infrastructure). The war game simulator mainly deal with the engagement of troops and the troops communicate each other at the mission execution level. In the other hand, The communication effect simulator perform communication actions between the troops in the engineering level. Using the interoperation simulation, we can reflect the communication effects on the war game simulation. We show various applications of the interoperation simulation with the point of the war game and communication effect simulator. with a case study, we explain the interoperation simulation improves the reality and fidelity of the war game simulator and how the interoperation simulation can be applied to developing doctrines and real communication system.

President Lee, Syngman was ROK supreme commander at the Korean war. But, it is doubt that he executed his authority and responsibility by the ROK constitution and law. At the phase of the Korean War conduct, his role may be divided into 'military operation execution one' and 'political-diplomacy one'. He appointed unqualified person to the important position of the national defence, didn't make war execution system, and was not make to meet the war. And, after transferring the ROK force operation commanding authority to the Commander in Chief, UN Command, his role was extremely trivial at the military operation execution phase. Any way, he intended to recover the inferior national strength and military capacity with USA aid, and concentrated his effort toward diplomacy with USA. At last, he succeeded in making a mutual defence treaty and gained a big result to harden Korea national security after war. In sum, president Lee was shrewd politician and diplomat than military leader. And, it can be evaluated that he supplemented the lost part of military affairs side with diplomat one.

The food life of Korean people during the establishment of Republic of Korea and the Korean war was reviewed. After liberation in 1945, the division of South and North Korea, the establishment of the governments, and the ensuing Korean War made Korean society extremely chaotic and transformed. Consequently, data on Korean dietary life during this period (1945-1960) are scarce and unreliable. The author tried to reveal the food situation and health and nutritional status of Koreans during this period by examining the data released by the US National Archives and other review books. Regarding the nascent period of the food industry after the Korean War, data from the recent 50-year history of the Korea Food Industry Association has been compiled.

Theorists of war have often used Clausewitz's trinity theory as a framework for analyzing war strategies and histories. Heretofore, studies on cyber warfare have focused primarily on laws, policies, structuring organizations, manpower, and training pertaining to preparing the cyberspace for war. Currently, studies highlighting the comparative characteristics of war in cyberspace, how it differs from conventional warfare, and analytical frameworks for understanding war in cyberspace are rare. Using Clausewitz's trinity theory, this paper interprets the essence of war from the perspectives of (1) Intellect, (2) Bravery, and (3) Passion, to propose an analytical model for understanding war in cyberspace, one that factors in the intrinsic qualities and characteristics of cyberspace under spatial and temporal constraints. Furthermore, this paper applies the aforementioned analytical model to the Iraq War and concludes with a theoretical illustration that cyber warfare played a significant role in winning the war.

As the first of Philip Roth's recent series of novels that delve into American Cold War history deeply entwined with the post-war Jewish American experience, American Pastoral traces the tragic fall of a third-generation Jewish American named Seymour "Swede" Levov, whose dream of complete assimilation to the post-ethnic American paradise is irrecoverably disrupted when his young daughter blows up the local post office to protest against the Vietnam War. This essay proposes to examine Swede Levov's interrupted pursuit of the American dream by locating it within specific Cold War contexts and national imaginaries propagated particularly during the years from John F. Kennedy to Lyndon B. Johnson. In so doing, I will argue that Roth presents a paradoxical vision of Jewish American identity that could be acquired by performing perpetual self-effacement and submergence into the non-place of anonymity and doubleness, a mythic location of the post-ethnic Cold War American family. Levov's life becomes true part of the mythic narrative of American history when he realizes that his life, just like the nation's history, is a series of temporalities radically discontinued without any manageable detour ot divine bypass to cross over. Rather than indicating Roth's retraction from the postmodern understanding of subjectivity, the novel's historical realism, I will argue, serves to illuminate the postmodern conditions of American Cold War history and ethnic identity.

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.

The purpose of this study is to examine and analyze the Untied Nations' efforts for peace on Korean peninsular after CCF's participation in Korean War. The Untied Nation tried to negotiate th peace plan between two sides from the end of 1950. Once the CCF's entry into the war had been confirmed, the war situation moved to a new phase, and the UN forces, which had guided the war in an effort to destroy the NKP A forces, and to punish North Korea, had to set up new guidelines to cope with the new situation. Accordingly, in late November, 1950, the UN forces camp, mainly the US Joint Chiefs of Staff and the United Nations Command, discussed various options, such as an expansion of the war up to the Chinese territory, a cease fire along the 38th Parallel, or a forced and inevitable evacuation. The Korean delegation to the UN insisted that "the unification of Korea should be achieved only by victory in the war. The Chinese intervention in the war is a Challenge to the UN in the same way as the North Korean invasion. The UN participation in the war was to repulse the invasion. With the same spirit we should drive back the Chinese Communists." The Korean delegation also emphasized to the friendly nations the political objective and will of unification, and that a cease fire at a threshold of unification might return us to the status quo ante bellum, and would be contrary to the Korean nation's desire. At that time, particularly, the US strongly considered the employment of nuclear weapons as one of the new strategies to cope with the Chinese invasion. The international effects of these casual remarks were realized almost at once. The British Prime Minister who had not wanted the expansion of war in the Far East, especially from the view point of the interest of NATO's security, visited Washington. so the conference had a very important meaning for the UN forces' new strategy. On the other hand, at the UN, on the 5th of December, the very day Truman and Attlee agreed to seek a cease-fire under UN auspices, a group of thirteen Asian and Arab states proposed to ask China and North Korea not to cross the 38th Parallel, and sounded out both sides about a cease fire along the 38th Parallel. The United States and the United Kingdom gave their assent, but China and North Korea gave no direct response. The CCF, who were securing the initiative of operation, were not agreeable with the proposal of the UN forces. The Untied Nation has tried to negotiate th peace plan between two sides from the December of 1950 and January of 1951. The Untied Nations' has achieved great results to negotiate for the peace plan on Korean peninsular after CCF's participation in Korean War. It's the results considering both the operation situation and political opinions.

Purpose that studies the war history is to prevent the war in the advance through instruction that is gotten by understanding the past war and in case of emergency, it is to win victory in the war from the enemy by doing not commit a same mistake like the past war. For these reasons, many studies about the war history have proceeded continuously in domestic and outside the country, and those are being carried out in present. However, most of studies of the war history have been analyzed only on qualitative analysis. In this study, we want to suggest quantitative analysis method using simulation with qualitative analysis. As an example of study, we quantitatively analyzed the importance of logistics support on the Moscow expedition of Napoleon. Also, on the basis of this, we found failure factor of logistics support of Napoleon force and through this, deduced instruction. There is meaning that this paper suggested quantitative analytical method in terms of study of the war history with qualitative analytical method.
