First of all, I am interested in making a mathematical model for malaria transmission in Korea. Our recent work on the tsutsugamushi disease transmission gives us interesting idea to make a mathematical model for malaria transmission. The idea and model for malaria will be discussed in this talk. I will also talk about the problem to make some models in social science, such as National Pension and preserving National Treasures. -------------- Title: Mathematical Modelling for the Tsutsugamushi Disease Transmission and its Analysis Speaker: Byul Nim Kim, Yasuhisa Saito, Yongkuk Kim Affiliation: Department of Mathematics, Kyungpook National University, Korea Abstract: Tsutsugamushi disease is one of the most febrile illnesses occurring throughout Korea during fall, which is known as a vector-borne disease caused by the bite of mites with rickettsial bacteria *Oriental tsutsugamushi.* The mites have four-stage life cycles: egg, larva, nymph, and adult. However, *Oriental tsutsugamushi *can be transmitted only in the larva stage of mites because other stages(nymph and adult) do not feed onhosts. Although there have been many researches on tick-borne diseases, we have never seen any mathematical models on such a mite-borne disease so far. In the present work, we present a model of the disease and show and analyze the basic reproduction ratio *R0. *
