This study clarifies the causes of the repetitive occurrences of such phenomena as rinderpest, epidemic, famine, and tiger disasters recorded in the Joseon Dynasty Chronicle and the Seungjeongwon Journals in the period of great catastrophe, the late 17th century in which the great Gyeongsin famine (1670~1671) and the great Eulbyeong famine (1695~1696) occurred, from the perspective that they were biological exchanges caused by the new arrival of rinderpest in the early 17th century. It is an objection to the achievements by existing studies which suggest that the great catastrophes occurring in the late 17th century are evidence of phenomena in a little ice age. First of all, rinderpest has had influence on East Asia as it had been spread from certain areas in Machuria in May 1636 through Joseon, where it raged throughout the nation, and then to the west part of Japan. The new arrival of rinderpest was indigenized in Joseon, where it was localized and spread periodically while it was adjusted to changes in the population of cattle with immunity in accordance with their life spans and reproduction rates. As the new rinderpest, which showed high pathogenicity in the early 17th century, was indigenized with its high mortality and continued until the late 17th century, it broke out periodically in general. Contrastively, epidemics like smallpox and measles that were indigenized as routine ones had occurred constantly from far past times. As a result, the rinderpest, which tried a new indigenization, and the human epidemics, which had been already indigenized long ago, were unexpectedly overlapped in their breakout, and hence great changes were noticed in the aspects of the human casualty due to epidemics. The outbreak of rinderpest resulted in famine due to lack of farming cattle, and the famine caused epidemics among people. The casualty of the human population due to the epidemics in turn led to negligence of farming cattle, which constituted factors that triggered rage and epidemics of rinderpest. The more the number of sources of infection and hosts with low immunity increased, the more lost human resources and farming cattle were lost, which led to a great famine. The periodic outbreak of the rinderpester along with the routine prevalence of various epidemics in the 17thcentury also had influenced on domestic and wild animals. Due to these phenomenon, full-fledged famines occurred that were incomparable with earlier ones. The number of domestic animals that were neglected by people who, faced with famines, were not able to take care of them was increased, and this might have brought about the rage of epidemics like rinderpest in domestic animals like cattle. The great Gyeongsin and Eulbyeong famines due to reoccurrence of the rinderpest in the late 17th century linked rinderpester, epidemics and great famines so that they interacted with each other. Furthermore, the recurring cycle of epidemics-famines-rinderpest-great famines constituted a great cycle with synergy, which resulted in eco-economic-historical great catastrophes accompanied by large scale casualties. Therefore, the Gyeongsin and Eulbyeong famines occurring in the late 17th century can be treated as events caused by the repetition of various periodic disastrous factors generated in 1670~1671 and in 1695~1696 respectively, and particularly as phenomena caused by biological exchanges based on rinderpester., rather than as little ice age phenomena due to relatively long term temperature lowering.

Based on archival materials, the Xiangya's anti-epidemic history in a century from its establishment to 2020 is divided into 4 stages. The first stage (1906-1926), Edward Hicks Hume and YAN Fuqing, the founders of Xiangya, prevented and controlled smallpox and plague. The second stage (1929-1953), during the resumption of Xiangya, students prevented and controlled cholera, plague, dysentery, typhus, and other infectious diseases. In the third stage (1953-1999), in a peacetime, Xiangya actively fought against schistosomiasis, hydatidosis, malaria, leprosy, tuberculosis and other epidemics. The fourth stage (2000-2020), the era of Central South University. Medical staff in Xiangya fight SARS, influenza A (HN) flu, Ebola hemorrhagic fever, coronavirus disease 2019, etc. Over the past hundred years, Xiangya people joined together to spread benevolence and love, apply medical knowledge and skills, combat the epidemic and rescue people in difficulties, which made a great contribution to the motherland and the people.
