Vinylon
Vinylon, also known as Vinalon, is a synthetic fiber produced from polyvinyl alcohol, using anthracite and limestone as raw materials. Vinylon was first developed in Japan in 1939 by Ri Sung-gi, Ichiro Sakurada, and H. Kawakami. Trial production began in 1954 and in 1961 the massive February 8 Vinylon Complex was built in Hamhung, North Korea. Vinylon's widespread usage in North Korea is often pointed to as an example of the implementation of the ''Juche'' philosophy, and it is known as the ''Juche'' fiber. Vinylon is the national fiber of North Korea and is used for the majority of textiles, outstripping fiber such as cotton or nylon, which is produced only in small amounts in North Korea. Other than clothing, vinylon is also used for shoes, ropes, and quilt wadding. Japanese-Canadian textile artist Toshiko MacAdam used vinylon in her early works, as it was more economical than nylon. Vinylon is resistant to heat and chemicals but has several disadvantages: being stiff, hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyvinyl Alcohol
Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water- soluble synthetic polymer. It has the idealized formula H2CH(OH)sub>''n''. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water. Without an externally added crosslinking agent, PVA solution can be gelled through repeated freezing-thawing, yielding highly strong, ultrapure, biocompatible hydrogels which have been used for a variety of applications such as vascular stents, cartilages, contact lenses, etc. Uses PVA is used in a variety of medical applications because of its biocompatibility, low tendency for protein adhesion, and low toxicity. Specific uses include cartilage replacements, contact lenses, and eye drops. Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest a ...

Juche
''Juche'' ( ; ), officially the ''Juche'' idea (), is the state ideology of North Korea and the official ideology of the Workers' Party of Korea. North Korean sources attribute its conceptualization to Kim Il-sung, the country's founder and first leader. ''Juche'' was originally regarded as a variant of Marxism–Leninism until Kim Jong-il, Kim Il-sung's son and successor, declared it a distinct ideology in the 1970s. Kim Jong-il further developed ''Juche'' in the 1980s and 1990s by making ideological breaks from Marxism–Leninism and increasing the importance of his father's ideas. ''Juche'' incorporates the historical materialist ideas of Marxism–Leninism but also strongly emphasizes the individual, the nation state, and national sovereignty. ''Juche'' posits that a country will prosper once it has become self-reliant by achieving political, economic, and military independence. As Kim Jong-il emerged as Kim Il-sung's likely successor in the 1970s, loyalty to the leader w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography.

Liberation Of Korea
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be w ...

Communist Countries
A communist state, also known as a Marxist–Leninist state, is a one-party state that is administered and governed by a communist party guided by Marxism–Leninism. Marxism–Leninism was the state ideology of the Soviet Union, the Comintern after Bolshevisation and the communist states within the Comecon, the Eastern Bloc and the Warsaw Pact. Marxism–Leninism currently still remains the ideology of a few parties around the world. After its peak when many communist states were established, the Revolutions of 1989 brought down most of the communist states, however, it is still the official ideology of the ruling parties of China, Cuba, Laos, and Vietnam. During most of the 20th century, before the Revolutions of 1989, around one-third of the world's population lived under communist states. Communist states are typically authoritarian and are typically administered through democratic centralism by a single centralised communist party apparatus. These parties are usually M ...
