The origins of Kyushu University (九州大学 Kyūshū Daigaku ) in Fukuoka, Japan, lie in the establishment of Fukuoka Medical College in 1903, affiliated with Kyoto Imperial University.
 In 1911, the Kyushu Imperial University was founded.
 In 1947, after World War II ended, the university changed its name to Kyushu University.
 The University is composed of six campuses: Chikushi, Hospital, Ito, Ohashi, Hakozaki, and Beppu.
 There are numerous historic buildings dating back to the many phases of history the university has seen.
 The Third Residential Complex on-campus has a western-style design and is reserved for foreign students.
 The complex dates back to 1924 and has been designated as a Municipal Cultural Property.
Omak Airport (IATA: OMK, ICAO: KOMK, FAA LID: OMK) , also known as Omak Municipal Airport or Omak City Airport, is a regional airport located 3 mi north of Omak, Washington, a city in the Okanogan region of United States.
 It is owned and operated by the Omak City Council and serves Omak, although it is situated in nearby town Riverside's city limits rather.
 The airport was built by the United States Army Air Forces around 1942 and was approved for public use the following year.
 After World War II ended, it was closed and turned over for local government use by the War Assets Administration (WAA).
 Throughout its history, a number of improvements and expansions have occurred with its terminal, runways and taxiways, specifically in June 1979, when improvements made around that month were celebrated with an air show presentation.
Hirō "Hiroo" Onoda (小野田 寛郎 , Onoda Hirō , 19 March 1922 – 16 January 2014) was an Imperial Japanese Army intelligence officer who fought in World War II and was a Japanese holdout who did not surrender in 1945.
 After Onoda spent 29 years holding out in the Philippines, his former commander traveled from Japan to personally issue orders relieving him from duty in 1974.
 He held the rank of second lieutenant in the Imperial Japanese Army.
West German Art Pottery is essentially a term describing the time period of 1949-1990 and became the early way to describe the pottery because the country of origin was often the only "mark" on the base.
 Even though company names are now better known, and many items are attributed to specific makers, the more generic term "West German pottery" remains in common use.
 "Fat Lava" is a popular term that refers to a fairly small subcategory of glazes but is all too often improperly used as a synonym for W. German pottery.
 While, World War II ended in 1945, the next 4 years were the "zone" era with the country into the "US Zone", "Russian/Soviet Zone", "British Zone", and "French Zone", and it was 1949 when the East/West division replaced the zones.
USS "Midway" (CVB/CVA/CV-41) was an aircraft carrier of the United States Navy, the lead ship of her class.
 Commissioned a week after the end of World War II, "Midway" was the largest ship in the world until 1955, as well as the first U.S. aircraft carrier too big to transit the Panama Canal.
 A revolutionary hull design, based on the planned "Montana"-class battleship , gave her enhanced protection compared to previous carriers.
 She operated for 47 years, during which time she saw action in the Vietnam War and served as the Persian Gulf flagship in 1991's Operation Desert Storm.
 Decommissioned in 1992, she is now a museum ship at the USS "Midway" Museum, in San Diego, California, and the only remaining U.S. aircraft carrier commissioned right after World War II ended that was not an "Essex"-class aircraft carrier .
Einar "Pastor'n" Iversen (born 27 July 1930 in Mandal) is a Norwegian jazz pianist and composer and the son of a "pastor."
 He went into jazz after World War II ended.
 Through more than sixty years, he has played with everyone in Norwegian jazz.
Nude is the eighth studio album and a concept album released by the English progressive rock band Camel in January 1981.
 The album is based on a true story of a Japanese soldier (Hiroo Onoda) marooned on an island in World War II who doesn't know that the war is over.
 'Nude' derives from his family name 'Onoda'.
 Most of the album is composed of instrumentals with only a few tracks containing lyrics.
 The album's lyrics were mainly written by Susan Hoover, except "Please Come Home", which was written by Andrew Latimer.
 It was the last Camel album to feature original drummer Andy Ward.
The term Calabrian Diaspora refers to the migration of Calabrians away from Calabria (Southern Italy).
 It is estimated that five million Italians emigrated to the U.S. between the unification of Italy around 1870 and the Great Depression around 1930.
 World War I in 1914 marked a surge in the level of immigration.
 Italians continued to leave Italy in sizable numbers, notably during the periods between World Wars I and II, and again after World War II ended in 1945, a period of immigration that lasted into the 1980s.
Ralph Fesler Gates (February 24, 1893 - July 28, 1978) was the 37th Governor of the U.S. state of Indiana from 1945 to 1949.
 A lawyer and veteran of World War I, he is credited with returning his party to power after the Ku Klux Klan scandal in late 1920s that led to years of Democratic dominance of the state government during the Great Depression.
 His term in office focused primarily on encouraging economic growth as World War II ended through the improvement of the state highway system, education reform, and offering incentives for industrial growth.
 After leaving office he remained active as a leader in the state Republican Party until his death.
"Crosley"-class high speed transports were high speed transport ships that served in the United States Navy during World War II.
 Some stayed in commission long enough to serve in the Korean War and the Vietnam War.
 All of them were converted from "Rudderow"-class destroyer escort s during construction except for  , which was converted a year after her construction.
 After World War II ended, several of the ships were sold to Mexico, South Korea, Taiwan, and Colombia.
