From ancient times to the present day, naval warfare in history is deeply connected with the rise and fall of countries. This study examines which countries won wars by tracing naval warfare that they had carried out. Seven Cases are traced for the analysis including the battle of Salamis and the Poeni War in the ancient period, the battle of Calais in the medieval and modern periods, the Russo-Japanese War in the modern period, and the Falklands War in the present age. The results show three fundamental characteristics. First, countries that won naval warfare were armed with the state-of-the-art weapon systems and conducted joint operations effectively. Second, countries that fought in the usual ways were defeated by challengers. Third, countries such as Athens, Rome, Britain and the United States ascended to the hegemony by winning major naval warfare and then commanding or controlling the sea at their own free will. Countries defeated in these naval warfare, however, descended to the weak powers. In general, countries that won warfare have a tendency to make light of defeated countries, not to introduce new weapon systems from abroad, and to stick to their traditional ways of fighting. These lessons indicate that the ROK military needs to continue the development of new weapon systems at peacetime. In addition, they show that it needs to focus more on the articulation of military doctrines and training systems so that warriors on the battlefield can fight better.

임진왜란에 발생한 전투 중 부산포 해전은 이순신 장군이 일본의 근거지를 직접 공격하여 대규모의 타격을 입힌 의미 있는 해전이다. 이 연구는 임진 4차 출전 시 부산포 일대의 전투에 대하여 지금까지의 역사적 인문학적 크고 작은 성과를 종합하고 적용하여 2차원과 3차원적인 공간속에서 재현하고자 한 것이다. 이를 위하여 부산포 해전장 주변의 고지도, 조선과 왜구의 선박, 선박의 이동과 전투 시 행해졌던 진형, 그리고 사거리 등을 적용하여 입체적으로 가시화 하였다. 특히 부산성 주변 해안에 일본의 선박이 주둔한 곳을 추정하고 가시화하기 위하여 다양한 역사적 자료와 성과를 활용하는데 주목하였다

본 연구는 난중일기의 기록 중 이순신 장군이 명량해전 이후 한반도 서남해안을 항해하면서 조선수군의 새로운 본영을 물색하고, 명량해전 이후의 조선수군의 전략을 구상하던 장소로서 전시 임시 전략지휘소로서 의미가 큰 안편도(발음도)의 현재의 지명으로 추정되는 섬들 중 팔금도를 대상으로 항해 과학적 관점에서 조명하고 분석한 내용이다. 분석 결과 이순신 장군과 그의 참모들이 올라가 주변을 조망한 위치로 추정되는 섬 중의 하나인 팔금도의 채일봉과 금당산에서 관측한 방향이 난중일기에 기록된 내용과 일치하지 않은 부분이 많음을 확인하였다.

Cruiser Dmitri Donskoi was constructed in 1895. During the Russo-Japanese War (1904-1905), she was damaged in an attack by Japanese destroyers at the battle of Tsushima, and scuttled in the east sea of Ulleungdo, Korea Peninsula on the 29th May 1905. In 2003, Dmitri Donskoi was found at the distance of 2 km off the east coast of Ulleung Island and at the depth of 400 m. Archival research was performed as the preliminary study for investigating the sunken ship.

We examined five astronomical variables formulas of the two conventional harmonic prediction programs (IOS tidal package (IOS) and Task-2000 tidal package (Task2K)) in relation to hindcast of paleo-tides and -tidal currents on historical navel battlefields such as Myeongryang Naval Battle (September 16th, 1597 according to the lunar calendar). Through the comparison of the resultant values in a certain time (00:00 January 1) of each year (1801, 1800 and 1597) calculated from the two different formulas, we understood that the reason why Task2K is incapable of hindcating them in pre-19th century, Specifically, we found that the Task2K formulas directly using the Gregorian calendar date did not identify leap years in calculating astronomical variables beyond the period of 1801-2099. Therefore, the IOS's formulas, which use the day number referenced on midnight 1/1/0000, are recommended for use in hindcasting paleo-tides and -tidal currents on historical navel battles in pre-19th century.
