The Workers' Party of Korea (WPK) is the founding and ruling political party of the Democratic People's Republic of Korea (North Korea), and the largest party represented in the Supreme People's Assembly.
 The WPK is the sole governing party of North Korea, although it coexists "de jure" with two other legal parties making up the Democratic Front for the Reunification of the Fatherland.
 It was founded in 1949 with the merger of the Workers' Party of North Korea and the Workers' Party of South Korea.
 The WPK also controls the world's 5th largest armed force – Korean People's Army.
 This political party (and all of the other parties in the DPRK) remains illegal in South Korea (officially the Republic of Korea) under South Korea's own National Security Act and is sanctioned by Australia, the European Union, the United Nations and the United States.
North Korea–Norway relations (Korean: 노르웨이-조선민주주의인민공화국 관계 ) refers to the current and historical relationship between Norway and the Democratic People's Republic of Korea (DPRK), commonly known as North Korea.
 Neither country maintains an embassy in the other, although North Korea formerly had an embassy in the Norwegian capital Oslo.
 The Norwegian ambassador in Seoul is also accredited to North Korea, as is the North Korean one in Stockholm to Norway.
The Kippumjo or Gippeumjo (translated variously as "Pleasure Group", "Pleasure Groups", "Pleasure Squad", "Pleasure Brigade", or "Joy Division") is an alleged collection of groups of approximately 2,000 women and girls that is maintained by the head of state of North Korea for the purpose of providing pleasure, mostly of a sexual nature, and entertainment for high-ranking Workers' Party of Korea (WPK) officials and their families, as well as occasionally distinguished guests.
Time in North Korea is given by Pyongyang Time (Chosŏn'gŭl: 평양시간 , Hancha: 平壤時間 or PYT) or Standard Time of the Democratic People's Republic of Korea (Chosŏn'gŭl: 조선민주주의인민공화국 표준시간 , Hancha: 朝鮮民主主義人民共和國標準時間 ), which is 8 ⁄ hours ahead of UTC () and has been the standard time zone in North Korea since 15 August 2015.
 When it is midnight (00:00) UTC, it is 8:30 a.m. (08:30) Pyongyang Time.
 Like South Korea, North Korea does not currently observe daylight saving time.
 Time keeping in North Korea is under the State Commission for Science and Technology.
The Rungna People's Pleasure Ground is an amusement park located in Pyongyang, North Korea.
 It was opened in 2012 in a ceremony with Kim Jong Un and his wife Ri Sol-ju.
 It has a dolphinarium, swimming pool, and a mini golf course.
Ri Sol-ju or Lee Seol-ju (Hangul: 리설주 ; Hanja: 李雪主 ; RR: "Ri Seol-ju "; MR: "Ri Sŏlju " ) (born 1985–89) is the First Lady of North Korea and the wife of Korean leader Kim Jong-un.
 North Korean state media has officially identified her as "his wife, Comrade Ri Sol-ju".
The Communist movement in Korea emerged as a political movement in the early 20th century.
 Although the movement had a minor role in pre-war politics, the division between the communist North Korea and the anti-communist South Korea came to dominate Korean political life in the post-World War II era.
 North Korea, officially the Democratic People's Republic of Korea, continues to be a Juche "socialist" state under the rule of the Workers Party of Korea.
 In South Korea, communism remains illegal through the National Security Law.
 Due to end of economic aid from Soviet Union after Dissolution of the Soviet Union in 1991 and impractical ideological application of Communist economy in North Korea over years of economic slowdown in 1980s and receding during 1990s, North Korea replaced Communism with Juche ideology in its 1992 and 1998 Constitutional revision for the personal cult of Kim's family dictatorship and (albeit reluctanly) opening of North Korean market economy reform, though it still remains a centrally planned economy with complete control of the state and agriculture with collectivized farms and state-funded education and healthcare.
New Zealand–North Korea relations (Korean:뉴질랜드-조선민주주의인민공화국 관계) refers to international relations between New Zealand and North Korea.
 Relations between the two countries have been almost non-existent since the division of Korea.
 During the Korean War in the 1950s, New Zealand troops fought as part of the United Nations force that repelled the North Korean invasion of South Korea.
 Since then, New Zealand and North Korea have had little contact, until July 2000 when North Korean Foreign Minister Paek Nam-sun and New Zealand Minister of Foreign Affairs Phil Goff met in Bangkok, leading to the establishment of diplomatic relations in March 2001.
 The New Zealand ambassador to South Korea based in Seoul is also cross-accredited to North Korea.
 In 2006, North Korea tested its first nuclear weapon, drawing criticism and suspension of relations by the New Zealand government, which holds a staunch anti-nuclear policy.
 New Zealand began re-establishing formal relations in 2007, when the New Zealand Minister of Foreign Affairs Winston Peters visited Pyongyang on November 20 to discuss possible political and economic deals with North Korea, on the basis that it start dismantling its nuclear weapons facilities.
Yeonsan-gun or Prince Yeonsan (23 November 1476 – 20 November 1506, r. 1494–1506), born Yi Yung or Lee Yoong, was the 10th king of Korea's Joseon Dynasty.
 He was the eldest son of Seongjong by his second wife, Lady Yoon.
 He is often considered the worst tyrant of the Joseon Dynasty, notorious for launching two bloody purges of the seonbi elite.
 He also seized a thousand women from the provinces to serve as palace entertainers, and appropriated the Seonggyungwan study hall as a personal pleasure ground.
 Overthrown, Yeonsan-gun did not receive a temple name.
Idora Park was a 17.5 acre Victorian era trolley park in north Oakland, California constructed in 1904 on the site of an informal park setting called Ayala Park on the north banks of Temescal Creek.
 Idora Park was leased by the Ingersoll Pleasure and Amusement Park Company that ran several eastern pleasure parks.
 What began as a pleasure ground in a rural setting for Sunday picnics evolved over time into the finest amusement park in the part of the San Francisco Bay Area.
 Popularity of the park declined after the advent of the automobile, and in 1929, Idora Park was razed.
