Joseon mummies have proved to be excellent subjects for scientific research on the health and disease statuses of pre-modern Korean peoples. Despite its academic significance, the origins of the Hoegwakmyo tomb in which the Joseon mummy was discovered have not yet been entirely revealed. Meanwhile, over the past several decades, there have been some reports on mummies and cultural artifacts preserved very well in the tombs of several Chinese dynasties (especially Song, Yuan, Ming and Qing). Although the Chinese tombs were very diverse in structure, we note that some graves among them were structurally very similar to Joseon Hoegwakmyo tombs. Before the Hoegwakmyo tomb in Korea, there were already similar tombs in China, inside which dead persons were mummified like the Joseon mummies. Considering that the Hoegwakmyo tomb of the Joseon Dynasty was established by the influence of the Confucian ideology, the Korean and Chinese mummies might share common cultural origins in history.

Previous studies have successfully shown evidence for parasitic infections in human remains from various archaeological sites. However, in the case of Korea, since there have been very few paleoparasitological reports published, pre-20th century parasitic infection patterns remain obscure. Therefore, in order to partly fill this gap, we are reporting on a case of paleoparasitic infection from the feces of a 15th century child mummy from Yangju, Korea. In the course of the present study, we found the eggs of Clonorchis sinensis, Ascaris lumbricoides, and Trichuris trichiura in the feces of the mummy. Trichuris trichiura eggs were found in far greater numbers than other parasite eggs; in fact, intact bipolar plugs were clearly observed and even the larvae were still visible in some eggs. The eggs of C. sinensis and A. lumbricoides were also well preserved, though not in as great a number. Since we could find a number of well-preserved larvae-containing eggs, we are encouraged that successful extraction, amplification, and sequence determination of ancient DNA from the paleoparasite eggs might be possible in future studies. With additional paleoparasitological investigation using feces from Korean mummies, we hope that a history of parasite infection in Korea will be reconstructed.

Purpose: To understand the domestication and spread of horses in history, genetic information is essential. However, mitogenetic traits of ancient or medieval horses have yet to be comprehensively revealed, especially for East Asia. This study thus set out to reveal the maternal lineage of skeletal horse remains retrieved from a 15 th century archaeological site (Gongpyeongdong) at Old Seoul City in South Korea. Methods:We extracted DNA from the femur of Equus caballus (SNU-A001) from Joseon period Gongpyeongdong site. Mitochondrial (mt) DNA (HRS 15128-16116)D-loop region of E. caballus was amplified by PCR. Cloning and sequencing was conducted for the mtDNA amplicons. The sequencing results were analyzed by NCBI/BLAST and phylogenetic tool of MEGA7 software. Results and Conclusion:The horse is unique among domesticated animals for the remarkable impact it has on human civilization in terms of transportation and trade. Utilizing the Joseon-period horse remains, we can obtain clues to reveal the genetic traits of Korean horse that existed before the introduction of Western horses. By means of mtDNA cytochrome b and D-loop analysis, we found that the 15 th century Korean horse belonged to haplogroup Q representing those horses that have historically been raised widely in East Asia.
