The integration of massively parallel sequencing (MPS) technology into forensic casework has been of particular benefit to the identification of unknown military service members. However, highly degraded or chemically treated skeletal remains often fail to provide usable DNA profiles, even with sensitive mitochondrial (mt) DNA capture and MPS methods. In parallel, the ancient DNA field has developed workflows specifically for degraded DNA, resulting in the successful recovery of nuclear DNA and mtDNA from skeletal remains as well as sediment over 100,000 years old. In this study we use a set of disinterred skeletal remains from the Korean War and World War II to test if ancient DNA extraction and library preparation methods improve forensic DNA profiling. We identified an ancient DNA extraction protocol that resulted in the recovery of significantly more human mtDNA fragments than protocols previously used in casework. In addition, utilizing single-stranded rather than double-stranded library preparation resulted in increased attainment of reportable mtDNA profiles. This study emphasizes that the combination of ancient DNA extraction and library preparation methods evaluated here increases the success rate of DNA profiling, and likelihood of identifying historical remains.

The weapons excavated from the de-militarized zones (DMZ) of Korea are vulnerable to corrosion due to the immediate and drastic environmental change. Especially, the chloride ions (Cl⁻) in iron weapons cause active corrosion and require removal. In this study, conservation treatment and de-salination was performed for the discovered weapons from excavation sites of soldiers killed in action during the Korean War. Furthermore, an attempt was made to prepare the most stable plan for conservation treatment through the comparative study of soaking weapons in distilled water without chemicals and in a solution of sodium (SSC) at different temperatures. In the preliminarily experiments, the comparison of the eluted Cl⁻ ions according to different conditions of de-salination showed that the highest number of ions were detected from the de-salination with SSC at a temperature of 100℃, and its duration was much smaller, i.e., 1∼2 weeks. Accordingly, for the parts from the guns and rifles amongst other objects, a six-time de-salination was conducted in the SSC solution for 8 hours at 100℃ and subsequently, for 16 hours at room temperature during which the distilled water and SSC were exchanged every week. However, in the case of a loaded rifle, the de-salination was not conducted, considering the risk that the high temperature and pressure by impregnation in vacuum could cause an explosion

This article discusses Mongolia’s 15 years of diplomatic efforts to join the United Nations, the main factors that influenced it, and the changing policies and positions of the Soviet Union, the Kuomintang of China, the United States, and other great powers. Although the Mongolian People’s Republic was able to join the United Nations in 1946, it was influenced by the Soviet Union’s communist position. Since 1946, Chiang Kai-shek’s Chinese policy and position have been a major obstacle. The history of the Republic of China, which existed on the mainland between 1912 and 1949, was the history of the struggle for power between the warlords, the history of the struggle between the Kuomintang and the Communists. In the nearly 40 years since the founding of the Republic of China in 1912, neither the warlords nor the Kuomintang have been able to exercise their sovereignty on the mainland, but they are keen to see Outer Mongolia as part of their territory. The Kuomintang was expelled from the mainland in 1949, shortly after 1946. During the Korean War, initiated by Kim Il-sung, Joseph Stalin and Mao Zedong, Mongolia stood firmly behind North Korea, providing both moral and material support. It has not been mentioned anywhere that this resulted in Mongolia’s efforts at the UN being postponed for many years. When Communist China entered the Korean War, the Kuomintang, which fully supported the US-led UN military operation (peacekeeping), not only continuously provoked at the Security Council of the United Nations, but also presented false documents about the MPR - described as “a Chinese territory seized by the Soviet Union” - sending troops to North Korea.The United States, which has recognized the status quo of the Mongolian People’s Republic, has made it clear that it has played an important role in the country’s admission to the United Nations. Thus Mongolia’s attempt finally succeeded and it became the 101st state to join the United Nations. As a consequence, Mongolia’s independence has been approved by a recognize of Western powers and it began to emerge out of its isolation, participate in decision of global issues, and cooperate with the international community. However, not only did this opportunity not be fully exploited, but due to the Cold War, Mongolia became a hotbed of ideological competition between the socialist and capitalist systems at the United Nations, the speakers’ rostrum Nevetheless,Post-Cold War, a whole new era of cooperation between Mongolia and the United Nations began.

The article explores the aspects of the interaction between the USSR and the USA on the Mongolian question within the UN during first 15 years of the Cold war. The author dwells such problems as Mongolia’s contribution to the war against Japanese militarism; the question of the involvement of Ulaanbaatar to the Korean war in 1950-1953; the arguments between Moscow and Washington concerning the package admittance of new members; the reason of the veto power exercised by the Chiang Kai-shek regime; ideological conflicts between two opposing blocs in the United Nations. The first application for Mongolia’s admission to the UN was submitted to Secretary-General Trygve Lie in a letter dated June 21, 1946, signed by Kh. Choibalsan, Prime-Minister and Minister of Foreign Affairs of the MPR. The solution of this issue, however, dragged on until 1961. During this period, the application for admission of the MPR was renewed four times - in 1948, 1955, 1956 and 1957. The Mongolian statement was considered at least 13 times in various meetings of the UN Security Council.
