Context paragraphs:
Korean Armistice Agreement: The Korean Armistice Agreement is the armistice which serves to ensure a complete cessation of hostilities of the Korean War.  It was signed by U.S. Army Lieutenant General William Harrison, Jr. representing the United Nations Command (UNC), North Korean General Nam Il representing the Korean People's Army (KPA), and the Chinese People’s Volunteer Army (PVA).  The armistice was signed on July 27, 1953, and was designed to "insure a complete cessation of hostilities and of all acts of armed force in Korea until a final peaceful settlement is achieved."  No "final peaceful settlement" has been achieved.  The signed armistice established the Korean Demilitarized Zone ("de facto" a new border between the two nations), put into force a cease-fire, and finalized repatriation of prisoners of war.  The Demilitarized Zone runs not far from the 38th parallel, which separated North and South Korea before the Korean War.

Anocha Panjoy: Anocha Panjoy (Thai: อโนชา ปันจ้อย ; rtgs: "Anocha Panchoi" ; born 1955) is a Thai national who was abducted by North Korean agents from Macau on 21 May 1978.  Her case only became known after the release of the American Charles Robert Jenkins and his Japanese family in 2004.

Charles Robert Jenkins: Charles Robert Jenkins (born February 18, 1940) is a former United States Army soldier who lived in North Korea from 1965 to 2004 after deserting from his unit and crossing the Korean Demilitarized Zone.

Camp Hovey: Camp Hovey is a United States Army military base in Dongducheon, Gyeonggi Province, South Korea.  It was named after Master Sergeant Howard Hovey who was killed in action at Pork Chop Hill during the Korean War.  The camp is adjacent to the larger Camp Casey connected by a road known as "Hovey Cut".  The nearest city to Camp Hovey is Dongducheon (also spelled Tongduch'on), which is roughly 15 mi from the Korean Demilitarized Zone (DMZ).  There is a south gate into Camp Hovey from Gwangam-dong village, but not as many things to do as outside Camp Casey's main gate.

Samsung SGR-A1: The Samsung SGR-A1 (or Samsung Techwin SGR-A1) is a type of sentry gun (a weapon that fires autonomously) that was jointly developed by Samsung Techwin (now Hanwha Techwin) and Korea University to assist South Korean troops in the Korean Demilitarized Zone.  It is widely considered as the earliest commercialized robot with autonomous capabilities and the first of its kind unit to have an integrated system that includes surveillance, tracking, firing, and voice-recognition.  While units of the Samsung SGR-A1 have been reportedly deployed, the number is unknown due to the project being "highly classified".

Bamboo Curtain: The Bamboo Curtain was the Cold War political demarcation between the Communist states of East Asia, particularly the People's Republic of China, and the capitalist and non-Communist states of the region.  To the north/northwest lay Communist China, the Soviet Union, Vietnam, and others.  To the south and east lay capitalist/non-Communist India, Japan, Indonesia, and others.  In particular, following the Korean War, the Korean Demilitarized Zone became an important symbol of this Asian division (though the term "Bamboo Curtain" itself is rarely used in that specific context).

Dorasan: Dorasan or Mount Dora is a 156-metre hill on the north bank of the Imjin River in northernmost Paju, South Korea.  It lies very near the Korean Demilitarized Zone.  The hill gives its name to several nearby landmarks, including Dorasan Station and the Mt. Dora Observatory, as well as to the local administrative unit Dorasan-ri.

Jangdan County: Jangdan County (read as "Jangdan-gun" in the Korean language) is a former county in Gyeonggi Province in Korea, which was divided into a northern part and a southern part when the USA and the Soviet Union jointly partitioned the Korean peninsula into two (the former controlled the southern half while the latter took over the northern half) during the division of Korea at the end of the Second World War towards the end of 1945.  The northern part of Jangdan County has since been merged into Changpung County in North Korea while the former county's southern part now makes up Yeoncheon County and the city of Paju in South Korea (the northern and the southern parts of Jangdan County are still situated along the border between North Korea and South Korea, which used to be positioned on the 38th Parallel but is now located at the Korean Demilitarized Zone (the Korean DMZ).

Axe murder incident: The axe murder incident (Korean: 판문점 도끼살인사건 ; Hanja: 板門店도끼殺人事件,도끼蠻行事件; literally, "Panmunjom axe murder incident") was the killing of two United States Army officers, Arthur Bonifas and Mark Barrett, by North Korean soldiers on August 18, 1976, in the Joint Security Area (JSA) located in the Korean Demilitarized Zone (DMZ).  The U.S. Army officers had been part of a work party cutting down a poplar tree in the JSA that partially blocked the view of United Nations (U.N.) observers when they were assaulted and killed by the North Koreans, who claimed that the tree was planted by Kim Il-Sung.

Korean Demilitarized Zone: The Korean Demilitarized Zone (DMZ; Hangul: 한반도 비무장 지대 ; Hanja: 韓半島非武裝地帶 ), informally known as the 38th Parallel, is a strip of land running across the Korean Peninsula.  It is established by the provisions of the Korean Armistice Agreement to serve as a buffer zone between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea).  The Demilitarized zone (DMZ) is a border barrier that divides the Korean Peninsula roughly in half.  It was created by agreement between North Korea, China and the United Nations in 1953.  The DMZ is 250 km long, and about 4 km wide.
