전투력 요소로 본 이순신의 전투준비태세와 초기전투 승리요인

This study focuses on how General Lee achieved continuous victories in the beginning of Japanese invasion. Unlike previous studies that focused on the victory factors on the water, this study focuses on analyses of General Lee’s combat preparation and emphasized combat capability during initial stages of battles, which defeated Japanese forces. The background of General Lee’s substantial war preparation came from the battle of Japanese invasion led by Hong-Yang in the Year of Jeong-Hae (1587). By developing the foundation for discipline and commanding system based on the past experience, Lee focused on creative, yet stuck to the basic war-preparation. One of Lee’s creative works was that he collected information of Japanese combat style to create his battle strategies: to deny enemy"s climbing up the warship, but to be close enough to target enemy ships with turtle ships, and to inspect the war preparations. For the war preparations, Lee inspected ships, various weapons, and defense system on the field. But most importantly, Lee’s victorious background originated from his nationally scaled propulsion for increasing the number of war-ships, development of cannons specially designed for battles against Japanese forces. When the actual Lim-Gin Japanese invasion occurred, Lee was fully prepared to go to the war against Japan by utilizing the effective reporting system, which reached to Right naval HQ located in Jeon-Ra provinces, observatory posts, and central government in a very short time. Lee also prepared for all possible routes of Japanese incomings and settled his navy on sea of Gyeong-Sang waiting for the imminent battle command from the government. In order to execute Command & Control system in the battle at the sea of Gyeong-Sang, Lee required strict command system, and hierarchy with Won-Gyun and Uk-Gi Lee’s fleet, which allowed well-coordinated strategic system. Also, strategy integrated intelligence, maneuver, fires, and force protections against Japanese Force. First, spot the enemy, approach with fleets during earl dawn when security is assured, then charge with turtle ships and full-on assailment of cannons with Pan-Ok ships to defeat Japanese Navy. After such strategy, Lee quickly ran away from the battle scene in order to prepare for the possible ambush attacks and buy some maintenance time for his navy. In summary, Lee achieved the victory via analyzing Japanese Navy’s current status, geography, water current, surround and attack strategy, ambush attacks, and effective maneuvers, which integrated with turtle ships and navy’s fire power. He also inspected his forces, fleets, and other weapons to sustain his combat capabilities. He distributed loots from the battles to his soldiers to alleviate their fear and fatigue. The most important victory factor would be Lee’s victory oriented leadership. His leadership highlighted field focused operations, principles, executions, and keen discernment, which contributed to flexible strategies, all with courage, fairness, people and his navy. In order to win the war, combat capability had to be performed at its best, and Lee’s victories at the initial battles exemplify preparation for the war and successful coordination of combat capability with his leadership in the naval battles.

우리는 먼저 單位元 1을 갖는 commutative ring의 prime ideal들과 primary ideal들에 대한 몇가지의 성질을 소개하자. 다음에 R이 하나의 Noetherian ring이고 M이 하나의 Noetherian module일때, 우리는 이들에 관한 몇가지 성질과 다음의 문제들에 대하여 증명하려고 한다. (1) 하나의 Noetherian ring R上의 finitely generated module M은 하나의 Noetherian module이다. (2) M을 하나의 Noetherian ring R上의 finitely generated module이라 하고, N과 N'를 M의 R-submodule들이라 하자. 이때 ol가 R의 하나의 ideal이라고 하면, r보다 큰 자연수 n에 대하여 ol^nN∩N'=ol^(n-r)(ol^rN∩N')을 만족하는 자연수 r이 존재한다.

Let k be an imaginary quadratic field, ℌ the complex upper half plane, and let ${\tau}{\in}k{\cap}$ℌ, q = exp(${\pi}i{\tau}$). And let n, t be positive integers with $1{\leq}t{\leq}n-1$. Then $q^{{\frac{n}{12}}-{\frac{t}{2}}+{\frac{t^2}{2n}}}{\prod}^{\infty}_{m=1}(1-q^{nm-t})(1-q^{nm-(n-t)})$ is an algebraic number [10]. As a generalization of this result, we find several infinite series and products giving algebraic numbers using Ramanujan's $_{1{\psi}1}$ summation. These are also related to Rogers-Ramanujan continued fractions.
