The naval history of Korea dates back thousands of years since the prehistoric times when simple fishing ships were used.
 Military naval history dates back to the Three Kingdoms period and Unified Silla dynasties of Korea in the 7th century.
 Because of the constant coastal attacks by the Wa Japanese and other barbarian tribes, Korean shipbuilding excelled to counter these threats as a result.
 During the Unified Silla period, Jang Bogo, a merchant, rose as an admiral and created the first maritime trading within East Asian countries.
 During the Goryeo dynasty, sturdy wooden ships were built and used to fight pirates.
 Korean shipbuilding again excelled during the Imjin war, when Admiral Yi defeated the advancing Japanese fleets.

 He was also a top naval historian, known as the "British Mahan", the leader of the British Royal Navy's intellectual revolution that stressed continuing education especially in naval history as essential to the formation of naval strategy.
 After serving as a "gadfly" to the British Admiralty, his constructive criticisms causing him to be "denied the role in the formation of policy and the reformations of naval education which his talents warranted", he served as the first Vere Harmsworth Professor of Imperial and Naval History at Cambridge University in 1934-1936, and Master of Downing College, Cambridge in 1934-1946.
John Whitby Allen (July 2, 1913 – January 6, 1973) was an American model railroader who created the HO scale Gorre & Daphetid model railroad in Monterey, California, and wrote numerous magazine articles on model railroading starting in the 1940s.
 Allen was renowned for his skill at scratch building and creating scenery.
 He also pioneered the technique of weathering his models for a more realistic appearance.
 In addition to his superdetailing of locomotives, rolling stock, structures, and scenery, Allen was known for populating his model world with scale figures in humorous scenes.
 Other techniques Allen promoted were realistic train operation and the use of forced perspective to create the illusion of a model railroad layout larger than it really was.

Railroad Model Craftsman is an American magazine specializing in the hobby of model railroading.
 The magazine is published monthly by White River Productions, which acquired the title from Carstens Publications in 2014.
 Its first issue in March 1933 was called The Model Craftsman because it covered other areas of scale modeling as well.
 Founded by Emanuele Stieri, it was second owner Charles A. Penn who helped grow the company and lead the publication towards the hobby of scale models.
 In April 1949 it changed its focus to model trains and changed its name to Railroad Model Craftsman reflect this change in editorial content.
 While it can claim to be the oldest model railroading magazine in continuous publication in the United States, rival "Model Railroader" counters with the tagline "Model railroading "exclusively" since 1934."
 (However, both were predated by "The Model Maker," which dates from 1924, and showcased working models of steam engines, trains, and boats.)
