World War II
World War II known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries; the major participants threw their entire economic and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China, it included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, the only use of nuclear weapons in war. Japan, which aimed to dominate Asia and the Pacific, was at war with China by 1937, though neither side had declared war on the other. World War II is said to have begun on 1 September 1939, with the invasion of Poland by Germany and subsequent declarations of war on Germany by France and the United Kingdom.
From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Finland and the Baltic states. Following the onset of campaigns in North Africa and East Africa, the fall of France in mid 1940, the war continued between the European Axis powers and the British Empire. War in the Balkans, the aerial Battle of Britain, the Blitz, the long Battle of the Atlantic followed. On 22 June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history; this Eastern Front trapped most crucially the German Wehrmacht, into a war of attrition. In December 1941, Japan launched a surprise attack on the United States as well as European colonies in the Pacific. Following an immediate U. S. declaration of war against Japan, supported by one from Great Britain, the European Axis powers declared war on the U.
S. in solidarity with their Japanese ally. Rapid Japanese conquests over much of the Western Pacific ensued, perceived by many in Asia as liberation from Western dominance and resulting in the support of several armies from defeated territories; the Axis advance in the Pacific halted in 1942. Key setbacks in 1943, which included a series of German defeats on the Eastern Front, the Allied invasions of Sicily and Italy, Allied victories in the Pacific, cost the Axis its initiative and forced it into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and turned toward Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in Central China, South China and Burma, while the Allies crippled the Japanese Navy and captured key Western Pacific islands; the war in Europe concluded with an invasion of Germany by the Western Allies and the Soviet Union, culminating in the capture of Berlin by Soviet troops, the suicide of Adolf Hitler and the German unconditional surrender on 8 May 1945.
Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August respectively. With an invasion of the Japanese archipelago imminent, the possibility of additional atomic bombings, the Soviet entry into the war against Japan and its invasion of Manchuria, Japan announced its intention to surrender on 15 August 1945, cementing total victory in Asia for the Allies. Tribunals were set up by fiat by the Allies and war crimes trials were conducted in the wake of the war both against the Germans and the Japanese. World War II changed the political social structure of the globe; the United Nations was established to foster international co-operation and prevent future conflicts. The Soviet Union and United States emerged as rival superpowers, setting the stage for the nearly half-century long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia.
Most countries whose industries had been damaged moved towards economic expansion. Political integration in Europe, emerged as an effort to end pre-war enmities and create a common identity; the start of the war in Europe is held to be 1 September 1939, beginning with the German invasion of Poland. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred and the two wars merged in 1941; this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935; the British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the fo
West Germany the Federal Republic of Germany, referred to by historians as the Bonn Republic, was a country in Central Europe that existed from 1949 to 1990, when the western portion of Germany was part of the Western bloc during the Cold War. It was created during the Allied occupation of Germany in 1949 after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom and France, its capital was the city of Bonn. At the onset of the Cold War, Europe was divided among the Eastern blocs. Germany was de facto divided into two countries and two special territories, the Saarland and divided Berlin; the Federal Republic of Germany claimed an exclusive mandate for all of Germany, considering itself to be the democratically reorganised continuation of the 1871–1945 German Empire. It took the line. Though the GDR did hold regular elections, these were not fair. From the West German perspective, the GDR was therefore illegitimate.
Three southwestern states of West Germany merged to form Baden-Württemberg in 1952, the Saarland joined the Federal Republic of Germany in 1957. In addition to the resulting ten states, West Berlin was considered an unofficial de facto 11th state. While not part of the Federal Republic of Germany, as Berlin was under the control of the Allied Control Council, West Berlin politically-aligned itself with West Germany and was represented in its federal institutions; the foundation for the influential position held by Germany today was laid during the Wirtschaftswunder of the 1950s when West Germany rose from the enormous destruction wrought by World War II to become the world's third-largest economy. The first chancellor Konrad Adenauer, who remained in office until 1963, had worked for a full alignment with NATO rather than neutrality, he not only secured a membership in NATO but was a proponent of agreements that developed into the present-day European Union. When the G6 was established in 1975, there was no question whether the Federal Republic of Germany would be a member as well.
Following the collapse of communism in Central and Eastern Europe in 1989, symbolised by the opening of the Berlin Wall, there was a rapid move towards German reunification. East Germany voted to dissolve itself and accede to the Federal Republic in 1990, its five post-war states were reconstituted along with the reunited Berlin, which ended its special status and formed an additional Land. They formally joined the Federal Republic on 3 October 1990, raising the number of states from 10 to 16, ending the division of Germany; the reunion did not result in a brand-new country. The expanded Federal Republic retained West Germany's political culture and continued its existing memberships in international organisations, as well as its Western foreign policy alignment and affiliation to Western alliances like UN, NATO, OECD and the European Union; the official name of West Germany, adopted in 1949 and unchanged since is Bundesrepublik Deutschland. In East Germany, the terms Westdeutschland or westdeutsche Bundesrepublik were preferred during the 1950s and 1960s.
This changed once under its 1968 constitution, when the idea of a single German nation was abandoned by East Germany, as a result West Germans and West Berliners were considered foreigners. In the early 1970s, starting in the East German Neues Deutschland, the initialism "BRD" for the "Federal Republic of Germany" began to prevail in East German usage. In 1973, official East German sources adopted it as a standard expression and other Eastern Bloc nations soon followed suit. In reaction to this move, in 1965 the West German Federal Minister of All-German Affairs Erich Mende issued the Directives for the appellation of Germany, recommending avoiding the initialism. On 31 May 1974, the heads of West German federal and state governments recommended always using the full name in official publications. From on West German sources avoided the abbreviated form, with the exception of left-leaning organizations which embraced it. In November 1979 the federal government informed the Bundestag that the West German public broadcasters ARD and ZDF had agreed to refuse to use the initialism.
The ISO 3166-1 alpha-2 country code of West Germany was "DE", which has remained the country code of Germany after reunification. ISO 3166-1 alpha-2 are the most used country codes, the "DE" code is notably used as country identifier extending the postal code and as the Internet's country code top-level domain.de. Accordingly the less used ISO 3166-1 alpha-3 country code of West Germany was "DEU", which has remained the country code of reunified Germany; the now deleted codes for East Germany, on the other hand, was "DD" in ISO 3166-1 alpha-2 and "DDR" in ISO 3166-1 alpha-3. The colloquial term "West Germany" or its equivalent was used in many languages. "Westdeutschland" was a widespread colloquial form used in German-speaking countries without political overtones. On 4–11 February 1945 leaders from the United States, the United Kingdom and the Soviet Union held the Yalta Conference where future arrangements as regards post-war Europe and strategy against Japan in the Pacific were negotiated.
The conference agreed that post-war Germany would be divided into four occupation zones: a French Zone in the far west.
South Korean won
The won or the Korean Won is the currency of South Korea. A single won is divided into the monetary subunit; the jeon is no longer used for everyday transactions, appears only in foreign exchange rates. The won is issued based in the capital city of Seoul; the old "won" was a cognate of Japanese yen. It is derived from the hanja 圓, meaning "currency" or "coin." The won was subdivided into 100 jeon, itself a cognate of the Chinese character 錢 which means "money" and used as a unit of money in ancient times. The current won is written in hangul only and does not have any hanja associated with it. Prior to 1910, the won was the currency. During the colonial era under the Japanese, the won was replaced by the Korean yen, at par with the Japanese Yen. After World War II ended in 1945, Korea was divided, resulting in two separate currencies, both called won, for the South and the North. Both the Southern won and the Northern won replaced the yen at par; the first South Korean won was subdivided into 100 jeon.
The South Korean won had a fixed exchange rate to the U. S. dollar at a rate of 15 won to 1 dollar. A series of devaluations followed, the ones, in part, due to the Korean War; the pegs were: The first South Korean won was replaced by the hwan on February 15, 1953 at a rate of 1 hwan = 100 won. Republic of Korea Banknotes 5th Edition In 1946, the Bank of Joseon introduced 10- and 100-won notes; these were followed in 1949 by 5- and 1,000-won notes. A new central bank, the Bank of Korea, was established on 12 June 1950, assumed the duties of Bank of Joseon. Notes were introduced in denominations of 5, 10 and 50 jeon, 100 and 1,000 won; the 500-won notes were introduced in 1952. In 1953, a series of banknotes was issued which, although it gave the denominations in English in won, were, in fact, the first issues of the hwan; the won was reintroduced on June 1962, at a rate of 1 won = 10 hwan. It became the sole legal tender on March 22, 1975, with the withdrawal of the last circulating hwan coins, its ISO 4217 code is KRW.
At the reintroduction of the won in 1962, its value was pegged at 125 won = US$1. The following pegs operated between 1962 and 1980: On February 27, 1980, efforts were initiated to lead to a floating exchange rate; the won was allowed to float on December 24, 1997, when an agreement was signed with the International Monetary Fund. Shortly after, the won was devalued to half of its value, as part of the East Asian financial crisis; until 1966, 10- and 50-hwan coins, revalued as 1 and 5 won, were the only coins in circulation. New coins, denominated in won, were introduced by the Bank of Korea on August 16, 1966, in denominations of 1, 5 and 10 won, with the 1 won struck in brass and the 5 and 10 won in bronze; these were the first South Korean coins to display the date in the common era, earlier coins having used the Korean calendar. The 10- and 50-hwan coins were demonetized on March 22, 1975. In 1968, as the intrinsic value of the brass 1-won coin far surpassed its face value, new aluminium 1-won coins were issued to replace them.
As an attempt to further reduce currency production costs, new 5- and 10-won coins were issued in 1970, struck in brass. Cupronickel 100-won coins were introduced that year, followed by cupronickel 50 won in 1972. In 1982, with inflation and the increasing popularity of vending machines, 500-won coins were introduced on June 12, 1982. In January 1983, with the purpose of standardizing the coinage, a new series of 1-, 5-, 10-, 50-, 100-won coins was issued, using the same layout as the 500-won coins, but conserving the coins' old themes; the Bank of Korea announced in early 2006 its intention to redesign the 10-won coin by the end of that year. With the increasing cost of production at 38 won per 10-won coin, rumors that some people had been melting the coins to make jewelry, the redesign was needed to make the coin more cost-effective to produce; the new coin is made of copper-coated aluminium with a reduced diameter of 18 mm, a weight of 1.22 g. Its visual design is the same as the old coin.
The new coin was issued on December 18, 2006. The 1- and 5-won coins are difficult to find in circulation today, prices of consumer goods are rounded to the nearest 10 won. However, they are still in production, minting limited amounts of these two coins every year, for the Bank of Korea's annual mint sets. In 1998, the production costs per coin were: 10-won coins each cost 35 won to produce, 100-won coins cost 58 won, 500 won coins cost 77 won; the Bank of Korea designates coin series in a unique way. Instead of putting those of similar design and issue dates in the same series, it assigns series number X to the Xth design of a given denomination; the series numbers are expressed with Korean letters used in alphabetical order, e.g. 가, 나, 다, 라, 마, 바, 사. Therefore, ₩1,000 issued in 1983 is series II because it is the second design of all ₩1,000 designs since the introduction of the South Korean won in 1962. In 1962, 10- and 50-jeon, 1-, 5-, 10-, 50-, 100- and 500-won notes were introduced by the Bank of Korea.
The first issue of 1-, 5-, 10-, 50-, 100- and 500-won notes was printed in the UK by Thomas De La Rue. The jeon notes together with a second issue of 10- and 100-won notes were printed domestically by the Korea Minting and Security Printing Corporation. In 1965, 100-won notes were printed using intaglio printing techniques, for the first time on domestically printed notes, to reduce counterfeiting. Replacements for the British 500-won notes followed in 1966 using intaglio printing, for the 50
1988 Summer Olympics
The 1988 Summer Olympics known as the Games of the XXIV Olympiad, was an international multi-sport event celebrated from 17 September to 2 October 1988 in Seoul, South Korea. In the Seoul Games, 159 nations were represented by a total of 8,391 athletes: 6,197 men and 2,194 women. 237 events were held and 27,221 volunteers helped to prepare the Olympics. 11,331 media showed the Games all over the world. These were the last Olympic Games for the Soviet Union and East Germany, as both ceased to exist before the next Olympic Games; the Soviets utterly dominated the medal table, winning 132 total medals. No country came close to this result after 1988; the games were boycotted by its ally, Cuba. Ethiopia and the Seychelles did not respond to the invitations sent by the IOC. Nicaragua did not participate due to financial considerations; the participation of Madagascar had been expected, their team was expected at the opening ceremony of 160 nations. However, the country withdrew because of financial reasons.
Nonetheless, the much larger boycotts seen in the previous three Summer Olympics were avoided, resulting in the largest number of participating nations during the Cold War era. Seoul was chosen to host the Summer Games through a vote held on 30 September 1981, finishing ahead of the Japanese city of Nagoya. Below was the vote count that occurred at the 84th IOC Session and 11th Olympic Congress in Baden-Baden, West Germany. After the Olympics were awarded, Seoul received the opportunity to stage the 10th Asian Games in 1986, using them to test its preparation for the Olympics. In its final Olympics, the Soviet Union utterly dominated the medal table winning 55 gold and 132 total medals. No country came close to this result after 1988. Soviet Vladimir Artemov won four gold medals in gymnastics. Daniela Silivaş of Romania won three and equalled compatriot Nadia Comăneci's record of seven Perfect 10s in one Olympic Games. After having demolished the world record in the 100 m dash at the Olympic Trials in Indianapolis, U.
S. sprinter Florence Griffith Joyner set an Olympic record in the 100-metre dash and a still-standing world record in the 200-metre dash to capture gold medals in both events. To these medals, she added a gold in the 4×100 relay and a silver in the 4×400. Canadian Ben Johnson won the 100 m final with a new world record, but was disqualified after he tested positive for stanozolol. Johnson has since claimed. In the Women's Artistic Gymnastics Team All-Around Competition, the U. S. women's team was penalized with a deduction of five tenths of a point from their team score by the Fédération Internationale de Gymnastique after the compulsory round due to their Olympic team alternate Rhonda Faehn appearing on the podium for the uneven bars during the duration of Kelly Garrison-Steve's compulsory uneven bars routine, despite not competing, having been caught by the East German judge, Ellen Berger. The U. S. finished fourth after the completion of the optional rounds with a combined score of 390.575, three tenths of a point behind East Germany.
This still remains controversial in the sport of gymnastics, as the U. S. performed better than the East German team and they would have taken the bronze medal in the team competition had they not been penalized or had an inquiry accepted to receive the points back. Phoebe Mills won an individual bronze medal on the balance beam, shared with Romania's Gabriela Potorac, making history as the first medal won by a U. S. woman in artistic gymnastics at a attended games. The USSR won their final team gold medals in artistic gymnastics on both the men's and women's sides with scores of 593.350 and 395.475 respectively. The men's team was led by Vladimir Artemov. Lawrence Lemieux, a Canadian sailor in the Finn class, was in second place and poised to win a silver medal when he abandoned the race to save an injured competitor, he arrived in 21st place, but was recognized by the IOC with the Pierre de Coubertin medal honoring his bravery and sacrifice. U. S. diver Greg Louganis won back-to-back titles on both diving events despite hitting his head on the springboard in the third round and suffering a concussion.
Christa Luding-Rothenburger of East Germany became the first athlete to win Olympic medals at the Winter Olympics and Summer Olympics in the same year. She added a cycling silver to the speed skating gold she won earlier in the Winter Olympics of that year in Calgary. Anthony Nesty of Suriname won his country's first Olympic medal by winning the 100 m butterfly, scoring an upset victory over Matt Biondi by.01 of a second. Swimmer Kristin Otto of East Germany won six gold medals. Other multi-medalists in the pool were Janet Evans. Swedish fencer Kerstin Palm became the first woman to take part in seven Olympics. Swimmer Mel Stewart of the U. S. was the most anticipated to win the men's 200 m butterfly final but came in 5th. Mark Todd of New Zealand won his second consecutive individual gold medal in the three-day event in equestrian on Charisma, only the second time in eventing history that a gold medal has been won consecutively. Baseball and Taekwondo were demonstration sports; the opening ceremony featured a mass demonstration of taekwondo with hundreds of adults and children performing moves in unison.
This was the last time the U. S. was represented by a basketball tea
South Korea the Republic of Korea, is a country in East Asia, constituting the southern part of the Korean Peninsula and lying to the east of the Asian mainland. The name Korea is derived from Goguryeo, one of the great powers in East Asia during its time, ruling most of the Korean Peninsula, parts of the Russian Far East and Inner Mongolia, under Gwanggaeto the Great. South Korea has a predominantly mountainous terrain, it comprises an estimated 51.4 million residents distributed over 100,363 km2. Its capital and largest city is Seoul, with a population of around 10 million. Archaeology indicates that the Korean Peninsula was inhabited by early humans starting from the Lower Paleolithic period; the history of Korea begins with the foundation of Gojoseon in 2333 BCE by the mythic king Dangun, but no archaeological evidence and writing was found from this period. The Gija Joseon was purportedly founded in 11th century BCE, its existence and role has been controversial in the modern era; the written historical record on Gojoseon was first mentioned in Chinese records in the early 7th century BCE.
Following the unification of the Three Kingdoms of Korea under Unified Silla in CE 668, Korea was subsequently ruled by the Goryeo dynasty and the Joseon dynasty. It was annexed by the Empire of Japan in 1910. At the end of World War II, Korea was divided into Soviet and U. S. zones of occupations. A separate election was held in the U. S. zone in 1948 which led to the creation of the Republic of Korea, while the Democratic People's Republic of Korea was established in the Soviet zone. The United Nations at the time passed a resolution declaring the ROK to be the only lawful government in Korea; the Korean War began in June 1950. The war lasted three years and involved the U. S. China, the Soviet Union and several other nations; the border between the two nations remains the most fortified in the world. Under long-time military leader Park Chung-hee, the South Korean economy grew and the country was transformed into a G-20 major economy. Military rule ended in 1987, the country is now a presidential republic consisting of 17 administrative divisions.
South Korea is a developed country and a high-income economy, with a "very high" Human Development Index, ranking 22nd in the world. The country is considered a regional power and is the world's 11th largest economy by nominal GDP and the 12th largest by PPP as of 2010. South Korea is a global leader in the industrial and technological sectors, being the world's 5th largest exporter and 8th largest importer, its export-driven economy focuses production on electronics, ships, machinery and robotics. South Korea is a member of the ASEAN Plus mechanism, the United Nations, Uniting for Consensus, G20, the WTO and OECD and is a founding member of APEC and the East Asia Summit; the name Korea derives from the name Goryeo. The name Goryeo itself was first used by the ancient kingdom of Goguryeo in the 5th century as a shortened form of its name; the 10th-century kingdom of Goryeo succeeded Goguryeo, thus inherited its name, pronounced by the visiting Persian merchants as "Korea". The modern spelling of Korea first appeared in the late 17th century in the travel writings of the Dutch East India Company's Hendrick Hamel.
Despite the coexistence of the spellings Corea and Korea in 19th century publications, some Koreans believe that Imperial Japan, around the time of the Japanese occupation, intentionally standardised the spelling on Korea, making Japan appear first alphabetically. After Goryeo was replaced by Joseon in 1392, Joseon became the official name for the entire territory, though it was not universally accepted; the new official name has its origin in the ancient country of Gojoseon. In 1897, the Joseon dynasty changed the official name of the country from Joseon to Daehan Jeguk; the name Daehan, which means "Great Han" derives from Samhan, referring to the Three Kingdoms of Korea, not the ancient confederacies in the southern Korean Peninsula. However, the name Joseon was still used by Koreans to refer to their country, though it was no longer the official name. Under Japanese rule, the two names Han and Joseon coexisted. There were several groups who fought for independence, the most notable being the Provisional Government of the Republic of Korea.
Following the surrender of Japan, in 1945, the Republic of Korea was adopted as the legal English name for the new country. Since the government only controlled the southern part of the Korean Peninsula, the informal term South Korea was coined, becoming common in the Western world. While South Koreans use Han to refer to the entire country, North Koreans and ethnic Koreans living in China and Japan use the term Joseon as the name of the country; the Korean name "Daehan Minguk" is sometimes used by South Koreans as a metonym to refer to the Korean ethnicity as a whole, rather than just the South Korean state. The history of Korea begins with the founding of Joseon in 2333 BCE by Dangun, according to Korea's foundation mythology. Gojoseon expanded until it controlled parts of Manchuria. Gija Joseon was purportedly founded in the 12th century BC, but its existence and role have been controversial in the modern era. In 108 BCE, the Han dynasty defeated Wiman Joseon and installed four commanderies in the n
Economic growth is the increase in the inflation-adjusted market value of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product, or real GDP. Growth is calculated in real terms - i.e. inflation-adjusted terms – to eliminate the distorting effect of inflation on the price of goods produced. Measurement of economic growth uses national income accounting. Since economic growth is measured as the annual percent change of gross domestic product, it has all the advantages and drawbacks of that measure; the economic growth rates of nations are compared using the ratio of the GDP to population or per-capita income. The "rate of economic growth" refers to the geometric annual rate of growth in GDP between the first and the last year over a period of time; this growth rate is the trend in the average level of GDP over the period, which ignores the fluctuations in the GDP around this trend. An increase in economic growth caused by more efficient use of inputs is referred to as intensive growth.
GDP growth caused only by increases in the amount of inputs available for use is called extensive growth. Development of new goods and services creates economic growth; the economic growth rate is calculated from data on GDP estimated by countries' statistical agencies. The rate of growth of GDP per capita is calculated from data on GDP and people for the initial and final periods included in the analysis of the analyst. In national income accounting, per capita output can be calculated using the following factors: output per unit of labor input, hours worked, the percentage of the working age population working and the proportion of the working-age population to the total population. "The rate of change of GDP/population is the sum of the rates of change of these four variables plus their cross products."Economists distinguish between short-run economic changes in production and long-run economic growth. Short-run variation in economic growth is termed the business cycle. Economists attribute the ups and downs in the business cycle to fluctuations in aggregate demand.
In contrast, economic growth is concerned with the long-run trend in production due to structural causes such as technological growth and factor accumulation. Increases in labor productivity have been the most important source of real per capita economic growth. "In a famous estimate, MIT Professor Robert Solow concluded that technological progress has accounted for 80 percent of the long-term rise in U. S. per capita income, with increased investment in capital explaining only the remaining 20 percent."Increases in productivity lower the real cost of goods. Over the 20th century the real price of many goods fell by over 90%. Economic growth has traditionally been attributed to the accumulation of human and physical capital and the increase in productivity and creation of new goods arising from technological innovation. Further division of labour is fundamental to rising productivity. Before industrialization technological progress resulted in an increase in the population, kept in check by food supply and other resources, which acted to limit per capita income, a condition known as the Malthusian trap.
The rapid economic growth that occurred during the Industrial Revolution was remarkable because it was in excess of population growth, providing an escape from the Malthusian trap. Countries that industrialized saw their population growth slow down, a phenomenon known as the demographic transition. Increases in productivity are the major factor responsible for per capita economic growth – this has been evident since the mid-19th century. Most of the economic growth in the 20th century was due to increased output per unit of labor, materials and land; the balance of the growth in output has come from using more inputs. Both of these changes increase output; the increased output included more of the same goods produced and new goods and services. During the Industrial Revolution, mechanization began to replace hand methods in manufacturing, new processes streamlined production of chemicals, iron and other products. Machine tools made the economical production of metal parts possible, so that parts could be interchangeable.
See: Interchangeable parts. During the Second Industrial Revolution, a major factor of productivity growth was the substitution of inanimate power for human and animal labor. There was a great increase in power as steam powered electricity generation and internal combustion supplanted limited wind and water power. Since that replacement, the great expansion of total power was driven by continuous improvements in energy conversion efficiency. Other major historical sources of productivity were automation, transportation infrastructures, new materials and power, which includes steam and internal combustion engines and electricity. Other productivity improvements included mechanized agriculture and scientific agriculture including chemical fertilizers and livestock and poultry management, the Green Revolution. Interchangeable parts made with machine tools powered by electric motors evolved into mass production, universally used today. Great sources of productivity improvement in the late 19th century were railroads, steam ships, horse-pulled reapers and combine harvesters, steam-powered factories.
The invention of processes for making cheap steel were important for many forms
Transport in South Korea
Transportation in South Korea is provided by extensive networks of railways, bus routes, ferry services and air routes that criss-cross the country. South Korea is the third country in the world to operate a commercial maglev train. Development of modern infrastructure began with the first Five-Year Development Plan, which included the construction of 275 kilometers of railways and several small highway projects. Construction of the Gyeongbu Expressway, which connects the two major cities of Seoul and Busan, was completed on 7 July 1970; the 1970s saw increased commitment to infrastructure investments. The third Five-Year Development Plan added the development of seaports; the Subway system was built in Seoul, the highway network was expanded by 487 km and major port projects were started in Pohang, Masan and Busan. The railroad network experienced improvements in the 1980s with electrification and additional track projects. Operation speed was increased on the main lines. Though the railroad was still more useful for transportation of freight, passenger traffic was growing.
There was 51,000 kilometers of roadways by 1988. Expressway network was expanded to connect more major cities and reached a combined length of 1,539 kilometers before the end of the decade; the largest railway operator is Korail. Railway network is managed by Korea Rail Network Authority. Korea Train Express began service as Korea's first high-speed service. Intercity services are provided by Mugunghwa-ho. ITX-Saemaeul stops less than Mugunghwa-ho, they stop. On routes where KTX operates, air travel declined with less passengers choosing to fly and airlines offering fewer flights. Nuriro Train service runs between other lines. Nuriro Train serves commuters around Seoul Metropolitan Area, providing shorter travel time than Seoul Subway; the rapid trains have same seat reservation as Mugunghwa-ho. Korail plans to expand the service area. South Korea's six largest cities — Seoul, Daegu, Gwangju and Incheon — all have subway systems. Seoul's subway system is the oldest system in the country, with the Seoul Station – Cheongnyangni section of Line 1 opening in 1974.
The first tram line in Seoul started operation between Seodaemun and Cheongnyangni in December 1898. The network was expanded to cover the whole downtown area as well as surrounding neighbourhoods, including Cheongnyangni in the east, Mapo-gu in the west, Noryangjin across the Han River to the south; the networks reached its peak in 1941, but was abandoned in favor of cars and the development of a subway system in 1968. Seoul Subway Line 1 and Line 2 follow the old streetcar routes along Jongno and Euljiro, respectively. All towns in South Korea of all sizes are served by regional bus service. Regional routes are classified as gosok bus or sioe bus with gosok buses operating over the longer distances and making the fewest stops en route. Shioe buses operate over shorter distances, are somewhat slower, make more stops. Within cities and towns, two types of city bus operate in general: dosihyeong or ipseok. Both types of bus serve the same routes, make the same stops and operate on similar frequencies, but jwaseok buses are more expensive and offer comfortable seating, while doshihyeong buses are cheaper and have fewer and less comfortable seats.
Many small cities and towns do not have jwaseok buses and their buses are called nongeochon. Some cities have their own bus classifying systems. Incheon International Airport is served by an extensive network of high-speed buses from all parts of the country. Beginning in the late 1990s, many department stores operated their own small networks of free buses for shoppers, but government regulation, confirmed by a court decision on June 28, 2001, have banned department stores from operating buses. However, most churches, daycare centres and private schools send buses around to pick up their congregants, patients or pupils. Highways in South Korea are classified as freeways, national roads and various classifications below the national level. All freeways are toll highways and most of the expressways are built and operated by Korea Expressway Corporation; the freeway network serves most parts of South Korea. Tolls are collected using an electronic toll collection system. KEC operates service amenities en route.
There are several financed toll roads. Nonsan-Cheonan Expressway, Daegu-Busan Expressway, Incheon International Airport Expressway, Seoul-Chuncheon Expressway and parts of the Seoul Ring Expressway are wholly funded and operated BOT concessions. Donghae Expressway was built in cooperation between the National Pension Service. Total length of the South Korean road network was 86,989 km in 1998. Of this, 1,996 km was 12,447 km national roads. By 2009, combined length of the expressways had reached 3,000 km, it equal to the whole area of South Korea Virtually cut off from the Asian mainland, South Korea is a seafaring nation, with one of the world's largest shipbuilding industries and an extensive system of ferry services. South Korea operates one of the largest merchant fleets serving China and the Middle East. Most fleet operators are large conglomerates, while most ferry operators are small, private operators. There are 1,609 km of navigable waterways in South Korea, though use is restrict
