full_context: Document 1: United States in the Korean War: The first battle the Americans entered in the Korean War was the Battle of Osan, where about four hundred strong landed in Pusan airport on the first of July. The American troops were sent off to Taejon the next morning where Major General John H. Church the head of U.S. field headquarters was confident in the US troop's strengths to push back the North Koreans. On July fifth the troops were finally put to the test when North Korean tanks crept towards Osan. The four hundred infantryman of the U.S. also called Task Force Smith opened fire on the North Koreans at 8: 16 am. Only four of the North Korean tanks were destroyed and twenty - nine kept moving forward breaking the US line. At the end of the battle only two more North Korean Tanks and two regiments of North Korean infantry were destroyed. The US had lost the battle, revealing that the mere sight of US troops would not reverse the military balance in Korea. By early August, the North Korean troops had pushed back the US and South Korean troops all the way to Naktong River, which is located about thirty miles from Pusan. The two weeks of fighting following this resulted in the most casualties of US troops than any other equivalent period of this war. However, during this time the US pushed supplies and personnel to Korea and by the end of July South Koreans and US troops outnumbered the North Koreans, although the North had pushed back the US and South by an amazing amount the North had suffered over fifty thousand casualties. Also because North Koreas supply lines were so lengthy and with the US in control of the water and air replenishing there losses were slow.
Document 2: Samsung: In 1947, Cho Hong-jai, the Hyosung group's founder, jointly invested in a new company called Samsung Mulsan Gongsa, or the Samsung Trading Corporation, with the Samsung's founder Lee Byung-chull. The trading firm grew to become the present-day Samsung C&T Corporation. After a few years, Cho and Lee separated due to differences in management style. Cho wanted a 30 equity share. Samsung Group was separated into Samsung Group and Hyosung Group, Hankook Tire and other businesses.In the late 1960s, Samsung Group entered the electronics industry. It formed several electronics-related divisions, such as Samsung Electronics Devices, Samsung Electro-Mechanics, Samsung Corning and Samsung Semiconductor & Telecommunications, and made the facility in Suwon. Its first product was a black-and-white television set.
Document 3: Korean War: Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and matériel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.
Document 4: Samsung Telecommunications: In 1977 Samsung Electronics launched the Telecommunication Network, and in 1983 it initiated its mobile telecommunications business with the hope that this would become the company's future growth engine. In 1986, Samsung was able to release its first built - in car phone, the SC - 100, but it was a failure due to the poor quality. In spite of unsuccessful result Ki Tae Lee, the then - head of the Wireless Development Team, decided to stay in the mobile business. He asked the company to buy ten Motorola mobile phones for benchmarking. After 2 years of R&D Samsung developed its first mobile phone (or ``hand phone ''in Korea), the SH - 100 in 1988. It was the first mobile phone to be designed and manufactured in Korea. But the perception of mobile devices was very low and although Samsung introduced new models every year, each model sold only one or two thousand units.
Document 5: Battle of Taejon: The Battle of Taejon (14–21 July 1950) was an early battle of the Korean War, between American and North Korean forces. Forces of the United States Army attempted to defend the headquarters of the 24th Infantry Division. The 24th Infantry Division was overwhelmed by numerically superior forces of the Korean People's Army (KPA) at the major city and transportation hub of Taejon. The 24th Infantry Division's regiments were already exhausted from the previous two weeks of delaying actions to stem the advance of the KPA.
Document 6: Korean War: In the resulting Battle of Pusan Perimeter (August–September 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny matériel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.
Document 7: Samsung: In 1938, Lee Byung-chul (1910–1987) of a large landowning family in the Uiryeong county moved to nearby Daegu city and founded Samsung Sanghoe (삼성상회, 三星商會). Samsung started out as a small trading company with forty employees located in Su-dong (now Ingyo-dong). It dealt in dried-fish, locally-grown groceries and noodles. The company prospered and Lee moved its head office to Seoul in 1947. When the Korean War broke out, he was forced to leave Seoul. He started a sugar refinery in Busan named Cheil Jedang. In 1954, Lee founded Cheil Mojik and built the plant in Chimsan-dong, Daegu. It was the largest woollen mill ever in the country.Samsung diversified into many different areas. Lee sought to establish Samsung as leader in a wide range of industries. Samsung moved into lines of business such as insurance, securities and retail.
Document 8: Samsung Town: Samsung Electronics, Samsung C&T, and Samsung Life Insurance have built three buildings which are 44, 34 and 32 stories respectively. Samsung Town was designed by Kohn Pedersen Fox. Samsung Electronics and Samsung C&T have already begun to move into the houses while Samsung Life Insurance is leasing its property to Samsung Electronics and other affiliates.
Document 9: Korean War: On 25 November at the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then decimated the US 2nd Infantry Division on the UN forces' right flank. The UN Command retreated; the U.S. Eighth Army's retreat (the longest in US Army history) was made possible because of the Turkish Brigade's successful, but very costly, rear-guard delaying action near Kunuri that slowed the PVA attack for two days (27–29 November). On 27 November at the Korean eastern front, a U.S. 7th Infantry Division Regimental Combat Team (3,000 soldiers) and the U.S. 1st Marine Division (12,000–15,000 marines) were unprepared for the PVA 9th Army Group's three-pronged encirclement tactics at the Battle of Chosin Reservoir, but they managed to escape under Air Force and X Corps support fire—albeit with some 15,000 collective casualties.
Document 10: Korean War: The Battle of Osan, the first significant American engagement of the Korean War, involved the 540-soldier Task Force Smith, which was a small forward element of the 24th Infantry Division which had been flown in from Japan. On 5 July 1950, Task Force Smith attacked the North Koreans at Osan but without weapons capable of destroying the North Koreans' tanks. They were unsuccessful; the result was 180 dead, wounded, or taken prisoner. The KPA progressed southwards, pushing back the US force at Pyongtaek, Chonan, and Chochiwon, forcing the 24th Division's retreat to Taejeon, which the KPA captured in the Battle of Taejon; the 24th Division suffered 3,602 dead and wounded and 2,962 captured, including the Division's Commander, Major General William F. Dean.

Document 12: Samsung: Samsung was founded by Lee Byung-chul in 1938 as a trading company. Over the next three decades, the group diversified into areas including food processing, textiles, insurance, securities, and retail. Samsung entered the electronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s; these areas would drive its subsequent growth. Following Lee's death in 1987, Samsung was separated into four business groups – Samsung Group, Shinsegae Group, CJ Group and Hansol Group. Since 1990, Samsung has increasingly globalised its activities and electronics; in particular, its mobile phones and semiconductors have become its most important source of income. As of 2017, Samsung has the 6th highest global brand value.Notable Samsung industrial affiliates include Samsung Electronics (the world's largest information technology company, consumer electronics maker and chipmaker measured by 2017 revenues), Samsung Heavy Industries (the world's 2nd largest shipbuilder measured by 2010 revenues), and Samsung Engineering and Samsung C&T (respectively the world's 13th and 36th largest construction companies).

Document 15: United States in the Korean War: In response to North Korea's invasion into South Korea the United Nations convened to formulate a response. The U.N. demanded North Korea's immediate withdrawal and, when this was not met, United States Army General Douglas MacArthur was appointed supreme commander of U.N. forces. To halt the rapid progress of North Korean forces into the south Task Force Smith was deployed to the Korean front from Japan. Task Force Smith consisted of U.S. Army officers and regiments of the Army's 24th Infantry Division that were stationed in Japan as occupational forces. Unfortunately the 24th were under trained, poorly supplied, and outnumbered. The 24th offered very little resistance against the North Korean advance. American and South Korean troops were pushed south and in late July 1950 Task Force Smith was overrun in the city of Taejon. Troops from the Army's 25th Infantry Division were deployed to Taejon to establish a new line and pullout the decimated 24th I.D. This addition of combat troops did not stop the North Korean advance and both American and South Korean troops were pushed further south.
