亂中日記에 나타난 忠武公 李舜臣의 리더쉽 特性

최두환 순천향대학교이순신연구소 2005 이순신연구논총 Vol.- No.4

Recently Korea is faced with serious problems in terms of economy, society, government, national security, diplomacy, etc. Korea economy has suffered from a severe recession for a long time since 1997 crisis of foregin exchange. At this time of crisis, we need a great leader who can successfully overcomr all these problems. There was Admiral Yi Sun Sin 400 years ago who played a crucial role in winning the Imjin(壬辰) War against Japan. Japan invaded Chosun(朝鮮) in the year of Imjin. Japanese army conquered most of Chosun, but Admiral Yi, Chief of the Chosun Naval operation(三道水軍統制使), had successfully defended the seas, so that japan could not transport food and weapons from Japan to Chosun. Admiral Yi had won six great sea battles including battles. He could not obtain government support in terms of weapons, Hansan(閑山), Myung-lyang(鳴梁)manpower, food, and even the king's trust for the defense of the sea. He invented Turtle Warships(거북선) and organized peasant troops and fed them by fishing and farming. But he had successfully led the troops to destroy the strong fleets of Japan armed newly-invented guns. The results of the study charaterize the leadership of Admiral Yi Sun Sin as follows : First, his leadership had been significantly influenced by confucianism. His leading idea was deeply based on the Confucian thoughts of loyalty to the country (patriotism) and filial duty to his parents. Second, he was the paternalistic and subordinate-centered leader. He had shown his concern, affection, anxiety for subordinates (and people living around the naval bases) repeatedly in his war diary. Third, he was a leader of the decisiveness. He always prepared the battles in desperate situation, getting ready for death. Fourth, he valued the laws, disciplines, rules and regulations in commanding Chosun's Naval Forces, but he practiced them flexibly depending on the given situation. Fifth, he was a man of stern integrity and morality. He was highly disciplined and sternly moral. He was an ideal leaders of incorruption and clean hands. Sixth, he was a transformational leader with strong charisma, who could inspire his subordinates to achieve missions impossible, that is, to win numerous battles against well-armed Japanese fleets. Finally, Admiral Yi was an outstanding leader of creativity. He built the Turtle warships which played crucial roles in destroying enemy warships. In addition, he created a number of new strategies and tactics which were successfully used against Japanese Naval Forces. In other words, he created success-winning the war. In conclusion, there are numerous lessons that today's leaders of Korea need to learn from Admiral Yi's traits, styles, values, personalities, attitudes, and achievements. Their implications are important not only for military commanders, but also for political leaders, diplomats, businessmen (involved in economic war), and many others. They should lead the country so that the current crisis would be successfully overcome.

危難時代를 대비한 栗谷과 忠武公의 리더쉽

이서행 순천향대학교이순신연구소 2005 이순신연구논총 Vol.- No.4

In this paper, I analyzed the reform leadership of Yul'gok and loyal and self sacrificing leadership of Chungmugong. Yul'gok indicated that there are many problems in and out of domestic politics just as disability and absence of morality of the ruling class, corruption and disorder of administration, and destitute national economy, invasion of neighboring countries ect. He stressed that social reform is direly needed in those days. The six policy outlines which contain the jest of reform politic and patriotic leadership was the last report which reveal his belief of economic wealth and military strength one year before his death as defense minister bracing for the foreign invasion of the Chinese in the North and Japanese in the South. An account for Chungmugong in the world history can be summarized as remark of the Japan's general of the navy, Togoheihachiro who defeated Russian Baltic armada in the Korea strait. "It is much proper to campare myself with Nelson. But I can not match for Yi Sun Sin." Nelson and I went for war by staunch support of the state. But Yi Sun Sin fought for oneself without any support from state. In this paper, the Chungmugong leadership can be summarized as follows. Frist, leadership of sternness and benevolence. Second, leadership of eliminating corrupted practice. Third, leadership of maximizing efficiency in military adminstration and strategy. Forth, leadership of precise diagnosis of situation and being example for excellency. Fifth, leadership of caring his subordinate in morale and wellbeing by using whip and carrot. Sixth, leadership of royalty by overcoming penalty of degradation to private.

이순신의 리더십 분석을 통한 대학생 리더십 교육프로그램 개발방안

이웅규(Lee Woong Kyu),이영관(Lee Young Kwan) 순천향대학교 이순신연구소 2004 이순신연구논총 Vol.- No.3

21세기는 변화의 시대다. 그 변화는 민주적이고 도덕적이며 미래 지향적 모델을 담고 있다. 그것은 21세기 우리의 과제이기도 하다. 그러한 과제를 달성하기 위해 우리 교육은 새로운 시대의 요구와 우리 문화에 알맞게 교육정책, 교육프로그램, 학교 운영방식, 구조, 과업, 조직의 구성원 등이 점진적으로 모두 변해야 된다. 이러한 시대의 흐름에 적응하기 위해서는 먼저 교육행정가의 의식, 가치관 그리고 행위가 획기적으로 변해야 한다. 그리고 이에 따라 교육프로그램도 바뀌어야 한다. 그러나 우리나라 대학교육의 현실은 어떠한가? 대학은 사회가 급속히 변화함에 따라 교육 수요자의 기대와 요구의 증가, 교육 민주화로 인한 자율성 증대 등으로 보다 효과적이고 도덕적인 학교를 추구하며, 미래에 대한 교육적 비전을 제시해야 하는 막중한 위치에 있음에도 불구하고, 전체 대학생을 대상으로 그들의 교육적 신념이나 가치를 변화시키기보다는 사무적이며 관행적으로 사회에 내보내는 일에 치중하는 경향이 높다. 이러한 점에서 볼 때, 대학 교육프로그램의 질과 내용은 대학생 교육의 성패를 결정하는 매우 중요한 요인이라고 할 수 있다. 따라서 이제 대학은 전통적 교육프로그램의 한계를 극복할 수 있고, 이 시대의 변화에 도전할 수 있는 새로운 패러다임의 리더십을 발휘해야 하는 중요한 시기에 와있다고 볼 수 있다. 이러한 시대적 변화에 부응하기 위해 본 연구는 오랫동안 우리 민족의 정신적, 실제적 세계에 중대한 영향을 끼쳐 온 위대한 충무공 이순신의 가르침이 어떤 리더십의 특성을 강조하고 있는지를 고찰하여 우리나라 대학생의 리더십 교육프로그램 연구의 새 이론적․실제적 패러다임을 제시함으로서 이순신 연구를 교육프로그램과 연계하는 문제를 새롭게 조명해보고자 하는데 그 목적이 있다. 그런데 지금까지의 리더십 연구는 정치․경제․사회․문화적으로 성공하거나 높은 위치에 있는 사람들의 리더십 유형이나 특성에 대한 연구들이 주류를 이루고 있다. 즉 리더십을 단지 다른 사람들을 이끌어가고 지도하는 사람에게만 있는 것으로 간주하는 경향이 있어 이러한 결과를 초래하였다고 할 수 있다. 실제 그런 사람들이 리더로서의 많은 장점들을 가지고 있다. 하지만 여기서 제시하는 이순신 리더십은 누구나 잠재력을 가지고 있고, 누구나 교육과 훈련 프로그램에 참여함으로써 획득할 수 있는 것이다. 인간에게 있어 리더십 발달의 가장 결정적인 시기는 청소년기이다. 특히 대학생이 된 청소년기에 리더십을 발달시키지 못하면 위험행동에 빠지게 되며, 성공적인 성인기로의 진입이 어려워진다. 따라서 청소년 리더십과 아주 밀접한 관련을 맺고 있는 상황이론, 즉 누구나 리더십의 잠재력을 가지고 있고 개발할 수 있다는 사실에 기인하여 본 연구의 대학생 리더십 교육프로그램 개발의 중요성을 부각시킬 수 있다. 이에 본 연구는 우리나라에서 리더로서 청소년들의 리더십의 잠재력을 일깨울만한 리더십을 발휘하고 자신의 역량을 보여준 이순신 리더십에 대한 연구를 고찰함으로써 대학생 리더십 교육프로그램 개발을 이해하는데 기여하고자 한다. 서구 중심의 리더연구에서 우리나라의 상황에 가장 잘 어울리는 리더 연구뿐만 아니라 리더십의 특성 이해로서, 자라나는 청소년들의 역사체험 및 교육적 차원의 역할을 다할 수 있도록 하는 계기마련을 위해서, 또한 순천향대학교 이순신연구소의 리더십 체험의 방안을 제시하고자 한다. 또한 대학교육과 관련하여 학교교육을 통한 지방대학 인력의 적극적 양성과 평생교육지원, 진로지도강화 등의 차원에서 대학생의 학습주기(educational life-cycle)에 맞게 자신들에게 부족한 권력화(empowerment), 경험화 교육과 네트워크 형성교육을 강화하여 경쟁력 있는 인적자원을 만들기 위한 교육프로그램 개발방안을 제시하고자 한다. 이러한 연구의 목적을 위하여 청소년이 가장 존경하는 인물로 선정된 이순신이 갖고 있는 리더십의 특성을 알아보고, 변화하는 시대환경 패러다임에 맞는 리더십 역할 모델을 선정함으로써 대학생 스스로 리더로써 갖추어야 할 능력과 팀워크의 형성능력을 배양시키고자 한다. The study suggests the following developments to activate Educational Leadership Program through General LeeSunShin in Korea. It is necessary to make various efforts to develop for Educational Leadership Programs through General LeeSunShin . The purpose of this study is to explore leadership revealed in General LeeSunShin s life that has exerted a significant influence upon the substance of the spiritual and practical worlds, and to give Korean Educational Program the theoretical and practical paradigms of ideal leadership shown through General LeeSunShin. In 21st century of borderless business era, the circumstances around companies change very rapidly. Therefore, it is required for the leadership, which is responsible to lead participants effort and direction, to be presented to a new direction which is suitable for new paradigm. In order to investigate, the researcher examined this study through Descriptive Content analysis Method. Before discussing this research, the researcher simply illustrated the concept of leadership and various studies of General LeeSunShin s leadership based on theoretical background. Then, the researcher analyzed the leadership revealed in General LeeSunShin s life. This study not only supplies the explanation about the phenomenon of leadership but also makes it possible to recognize the importance of General LeeSunShin s leadership. Furthermore, this study intends to contribute to increase the leadership of youth through effective management of a university undergraduate.

임진왜란 시기 이순신의 해전술(海戰術)과 귀선(龜船)의 역할

제장명(Je, Jang Myeong) 순천향대학교 이순신연구소 2007 이순신연구논총 Vol.- No.9

임진왜란 시기 이순신 연구의 핵심은 그가 수행한 해전을 중심으로 이루어져야 한다. 그런데 기존 해전연구의 경향은 당시의 전선과 무기체계의 발전에 따라 다양해진 전술적 측면 에서의 분석이 아니라 이순신 자신의 탁월한 리더십과 전략전술 및 충성심이 충일한 군인정신 등을 위주로 이루어졌다. 따라서 객관적인 연구 성과 도출이 미흡하였다. 본고에서는 이순신 해전승리의 요체라 할 수 있는 그의 해전술에 대해 주목해 보았다. 따라서 전선과 무기체계의 발전을 근간으로 하여 개발 적용한 이순신의 해전술에 관해 살펴보 면서 당시 전라좌수군만이 보유한 귀선의 역할을 드러내 보았다. 이순신이 구사한 해전술은 매우 다양하고 독특한 형태를 보였다. 그중에서도 핵심은 바로 일본군의 등선을 거부하면서 아군의 장점인 화포의 명중률을 높이는 방향으로 전술이 구사 되었다. 그러한 전술적 특징 중에서 우리의 주목을 끈 것은 바로 귀선을 이용한 전술이었 다. 당시의 귀선은 판옥선이라는 선박제도의 우수성과 대형화포의 전선탑재로 인한 장점을 극대화할 수 있었던 전선이었다. 귀선은 선체의 장갑화로 인해 격군과 사부가 보호된 가운데 적선 가까이 접근이 가능하였다. 그리고 적선에 근접한 가운데 화포를 발사함으로써 명중률이 매우 높았다. 이러한 활약을 보인 귀선은 전라좌수영에서 처음 건조되어 전라좌수군이 중점적으로 활용 하였다. 다시 말해 임진왜란 시기 귀선을 이용한 전술은 전라좌수군만이 구사할 수 있었던 독특한 전술이었다. 그리고 한산대첩 때에는 수군승리의 핵심적 역할을 수행하여 임진왜란 극복의 동력으로 작용하였다. Studies on Yi Sunshin during Imjinwaeran must center on his naval battles. However, conventional studies on his naval battles were mostly about his excellent leadership, strategies and tactics, and faithful military spirit, rather than analyses of various strategies with the development of war ships and arms at the time. Consequently, objective study results were insufficient. This study focused on his naval tactics which are the secret to his victories in naval battles. While reviewing the naval battle tactics of Yi Sunshin which were based on the development of war ships and arms, this study revealed the role of the turtleship that only the Cheonra left navy possessed at the time. The naval tactics of Yi Sinshin were various and unique. The core of his tactics was to reject the climbing into the ship by the Japanese forces while improving the accuracy rate of the firearms which was the strength of our forces. What is noticeable about his tactics was the use of turtleships. Turtleship at the time was a war ship that could maximize the excellence of the ship system called Panokseon and the advantage of loading large firearms in a war ship. Turtleships could approach close to the opponent ships because the mariner and marksman were protected by the armor plate of the ship. Furthermore, their accuracy rate was very high because they fired the firearms while close to the opponent ships. These turtleships were first constructed by the Cheonra left station navy and used actively by the Cheonra left navy. In other words, the use of turtleships during Imjinwaeran was a unique tactic of the Cheonra left navy. During Hansan daecheop, the turtleships played the core role in the victory of the Choseon navy and acted as the driving force for overcoming the Imjinwaeran.

이순신과 경상좌수사 이운룡

제장명(Jang-Myeong Je) 순천향대학교 이순신연구소 2023 이순신연구논총 Vol.- No.38

임진왜란 시기 수군 활동에 있어서 이순신을 도운 주변 인물들의 활동도 전쟁 극복에 큰 기여를 하였다. 본고에서는 임진왜란 시기 경상좌수사를 역임하여 전쟁 극복에 힘쓴 이운룡(李雲龍)의 활동상을 이순신과의 관계 측면에서 살펴보았다. 이운룡은 임진왜란 시기 경상우수사 휘하 옥포 만호, 웅천 현감을 거쳐 경상좌수사로서 수군활동을 수행하였다. 좌수사 이순신과 잦은 접촉을 보이지 않았다. 그러다가 이순신과 최초로 접촉을 한 시점은『난중일기』의 기록을 볼 때 1594년 1월 20일이었다. 이때는 이운룡이 웅천 현감이었을 때다. 이순신과 이운룡이 접촉을 했지만 초기에는 거의 단순한 만남 위주였다. 그러다가 날이 갈수록 이순신과 접촉 빈도가 잦아들면서 함께 활도 쏘고 식사와 놀이도 함께 하는 모습을 확인할 수 있다. 그리고 중요한 업무와 전투 참전도 이루어졌다. 이러한 접촉 기록이『난중일기』에 보면 모두 51회이다. 이후 경상좌수사로 부임한 이운룡은 한산도와 경상좌도 사이에 일본군의 점령지가 가로막혀 있어서 직접 접촉이 불가능했다. 따라서 통제사 이순신의 지침에 따르는 것이 아니라 경상좌도의 전쟁 상황에 맞춰 명군 지휘부와 도원수 및 도체찰사 등의 지시에 따라 활동해야 했다. 그는 소수의 전력으로나마 제1, 2차 도산성 전투에서 나름의 활약을 하였다. 요컨대 이순신과 이운룡은 소속은 달랐지만 임진왜란 초기부터 접촉이 이루어지면서 해전 승리에 크게 기여하였다. 그리고 한산도에 통제영 행영을 설치하면서부터 둘 사이가 밀접해 짐에 따라 상호 인간관계가 돈독해 진 것으로 파악된다. 그리고 이순신은 이운룡의 능력과 인품을 인정하여 경상좌수사로 천거함에 따라 이운룡이 큰 활약을 할 수 있도록 하였다. During the Imjin War(1592~1598), the activities of the surrounding figures who helped Yi Sun-sin also contributed greatly to overcoming the war. In this paper, we looked at Lee Un-ryong's activities in terms of his relationship with Yi Sun-sin, who worked as a Gyeongsangjwasusa(慶尙左水使) during the Imjin War(1592~1598). During the Imjin War(1592~1598), Lee Un-ryong served as a naval officer as a commander of the Gyeongsang-Jwasusa(慶尙左水使) through Okpo Manho(玉浦萬戶) and Ungcheon hyungam (熊川縣監). Lee Woon-ryong was born in 1563 and is 18 years younger than Yi Sun-sin. In the early days of Imjin War(1592~1598), he was a key subordinate of Gyeongsang-Wususa(慶尙右水使) Won Gyun, As a result, in the early days, he did not show frequent contact with Jeolla-Jwasusa(全羅左水使) Yi Sun-sin. Then, the first contact with Yi Sun-sin was on January 20, 1594, when looking at the records of “Nanjung Ilgi.” This was when Lee Un-ryong was the Ungcheon hyungam. Yi Sun-sin and Lee Un-ryong made contact, but in the beginning, they were mostly simple meetings. Then, as the frequency of contact with Yi Sun-shin decreases as the days go by, you can see him shooting arrows, eating and playing together. And important work and combat participation were also carried out. According to the Nanjung Ilgi, these contact records are 51 times in total. Lee Un-ryong, who was later appointed as Gyeongsang-Jwasusa, was unable to contact directly because the Japanese military's occupied area was blocked between Hansando Island and Gyeongsang-jwado (慶尙左道). Therefore, it was not necessary to follow the guidelines of controller Yi Sun-sin, but to operate according to the instructions of the Myeonggun command, the head of the provincial government, and the conductor in accordance with the war situation in Gyeongsangjwa-do. He played his own role in the first and second battles of Dosan-Fortress(島山城), even with a small number of troops. In short, Yi Sun-sin and Lee Un-ryong had different affiliations, but contact was made from the beginning of the Imjin War, contributing greatly to the victory of the naval battle. In addition, it is understood that the mutual human relationship has become stronger as the two have become closer since the establishment of the control management center on Hansan-Island(閑山島). In addition, Yi Sun-sin recognized Lee Un-ryong's ability and personality and recommended him as a Gyeongsangjwasusa, allowing Lee Un-ryong to play a great role.

『난중일기』를 통해 본 한산도와 이순신의 건강

임원빈(Lim Won Bin) 순천향대학교 이순신연구소 2014 이순신연구논총 Vol.- No.22

이 글에서 필자는《난중일기》를 토대로 다음의 두 가지 주제를 살펴보았다. 첫째는 한산도이다. 여기서는 한산도에 조선 수군 전진기지가 설치되는 과정과 한산도에 만들어진 기지 시설 그리고 명나라 수군의 방문 내용을 살펴 보았다. 한산도는 처음에는 전라좌수영의 전진기지였으며, 이순신이 삼도 수군 통제사가 된 이후에는 삼도수군의 전진기지 역할을 하였다. 또한 조선에 원군을 파병한 명나라에서는 1593년 5월에 파견원 양보(楊甫)를 보내어 조선 수군의 전투력을 파악하였으며, 1594년 7월에는 명나라 수군 장수 장홍유(張鴻儒)가 직접 함선 5척을 거느리고 한산도를 방문하였다. 이를 통해 조선 수군의 전투력이 막강하다는 것을 확인한 명나라는 정유재란이 일어나기 전까지는 수군을 파병하지 않았다. 둘째는 이순신의 건강 문제이다. 이를 위해 이순신의 활쏘기 훈련과 연도별 건강 상태를 살펴보았다. 이순신은 1회 평균 50회의 활을 쏘았다. 몸의 상태가 좋을 때는 100회 더 나아가 150회를 쏘았다는 기록도 있다. 활쏘기는 이순신이 스스로의 건강을 단련시키는 유일한 운동이었다. 또 한편 이순신은 《난중일기》를 쓰기 시작한 1592년부터 전사할 때까지 아프지 않은 달이 거의 없을 정도로 건강 상태가 좋지 않았다. 어떤 달은 한 달 내내 몸이 아팠던 달도 있다. 임진왜란, 정유재란 시기 이순신의 건강은 그야말로 최악이었다. 아마도 그는 위장 계통, 소화기 계통이 약했던 것 같다. 그의 병의 증세를 보면, 몸이 아파서 신음을 하고, 소화가 안 되서 밥을 굶기도 하고, 토하기도 하며, 수시로 엄청난 땀을 흘렸다. 이순신은 밖으로는 왜적과 싸워야 했고 안으로는 자신의 건강과도 싸워야 했다. 그가 전쟁의 와중에 건강으로 인해 병사하지 않고, 왜적과의 마지막 전투에서 전사한 것은 그야말로 우리 후손에게는 커다란 축복이요 영광이 아닐 수 없다. In this article, the writer examines the two subjects mentioned above based on Nanjung-Ilgi. The first subject is about Hansando. In this analysis, the author studies the process of establishing Chosun Navy’s forward operating bases (FOB) in Hansando, the facility of the bases, as well as the details of Ming’s visits to Hansando. It was initially Jeolla-Jwasuyeong’s FOB but later became FOB of the Three Provinces’ naval forces after Admiral Yi Sun-shin was appointed as the naval commander of the Three Provinces. In May 1593, the Ming dynasty, which had sent reinforcements to Chosun, investigated the combat power of Chosun Navy by dispatching Yang-Bo. Then, in July 1594, Jang Hong-Yu, the commander of Ming’s Navy, led five vessels himself and personally visited Hansando. Confirming Chosun Navy’s mighty combat strength through the investigation, Ming did not dispatch troops to Chosun until the outbreak of the Jeongyujaeran. The second topic focuses on the physical condition of Admiral Yi Sun-Sin. The writer studies Yi’s archery practice and his annual health condition throughout the analysis. In each practice, the Admiral shot an average of 50 arrows. Records exist that he even shot 100 arrows or sometimes 150 arrows when he was feeling well. Archery was the only exercise he did to keep himself in good shape. On the other hand, since 1592, when Admiral Yi started composing Nanjung-Ilgi, to the year he died in action, he frequently suffered from the chronic illness every month. On some months, he was ill everyday. His physical condition during Japanese invasion of Korea in 1592 and 1597, especially, was at the worst. It is estimated that he had weak stomach and digestive system. The symptoms included moaning from pain, starving due to poor digestion, vomiting and producing large amount of sweat. Yi had to fight invading Japanese warriors on the outside, while also fighting his ailment on the inside. The fact that he died in action in the last battle against Japanese rather than dying from a disease is a great blessing and honour to us descendents.
