A chaebol ( ; ; from Korean "jaebeol" ] ) is a South Korean form of business conglomerate.
 They are typically global multinationals and own numerous international enterprises, controlled by a chairman with power over all the operations.
 The term is often used in a context similar to that of the English word "conglomerate".
 The term was first used in 1984.
 There are several dozen large Korean family-controlled corporate groups which fall under this definition.
Working hours in South Korea are quite long compared to other OECD countries because the working hours are related to Korean economic growth.
 Since the 1960s, economy of South Korea was begun to transform from agricultural economy]] into industrialized and high-technological economy.
 The South Korea’s per capita GDP sharply increased from US $100 in 1963 to US $35,300 in 2014 and finally South Korea becomes the country that has 20th largest economies in the world.
 In the process, many workers have contributed to increase GDP of South Korea and therefore working hours continuously increase at the same time.
 According to a research on OECD website, working hours in South Korea were 2,124 per worker in 2014.
 The figure shows Korea ranks 3rd highest working hour country compared to 1,789 hours in U.S., 1,677 hours in UK, and even the shortest 1,366 hours in Germany.
 In addition, the hourly minimum wage in South Korea is 6,030 won ($5.30) in 2016 and it will be increased to 6,470 won ($5.69) by the South Korean Minimum Wage Council in 2017.

A dispute exists over the international name for the body of water which is bordered by Japan, Korea (North and South) and Russia.
 In 1992, objections to the name Sea of Japan were first raised by North Korea and South Korea at the Sixth United Nations Conference on the Standardization of Geographical Names.
 The Japanese government supports the exclusive use of the name "Sea of Japan" (日本海), while South Korea supports the alternative name "East Sea" (Hangul: 동해 ; Hanja: 東海 ), and North Korea supports the name "Korean East Sea" (Chosŏn'gŭl: 조선동해 ; Hancha: 朝鮮東海 ).
 Currently, most international maps and documents use either the name Sea of Japan (or equivalent translation) exclusively, and far fewer maps include both the name Sea of Japan and East Sea, often with East Sea listed in parentheses or otherwise marked as a secondary name.
 The International Hydrographic Organization, the international governing body for the naming of bodies of water around the world, in 2012 decided not to change the current single name "Sea of Japan" rejecting South Korea's request to use "East Sea" together with "Sea of Japan".

The economy of South Korea is the fourth largest economy in Asia and the 11th largest in the world.
 It is a mixed economy dominated by family-owned conglomerates called chaebols, however, the dominance of chaebol is unlikely and at risk to support the transformation of Korean economy for the future generations.
 South Korea is famous for its spectacular rise from one of the poorest countries in the world to a developed, high-income country in just one generation.
