    「A Research for the Origin of Human Cultures in the Ryukyu Archipelago」
    YAMASAKI Shinji
    (Okinawa Prefectural Museum and Art Museum)

     A research about paleolithic human remains in Okinawa well developed through the excavations of Yamashita-cho cave site (Naha City) and Minatogawa site (Yaese Town) carried out from 1960s to 70s. But a big mystery was concerning to a living place and cultural remains of the palaeolithic people, because only human bones without any artificial material were found from those sites.
     Our new research project that aimed at the discovery of new human fossil and paleolithic artifact was planned in 2006, and we have conducted continuous excavations of limestone caves in the southern part of Okinawa-jima Island more than ten years. As a part of the project, we started the excavation of Sakitari-do cave site (Nanjo City) in 2009. As a result, well preserved sediments dated from approximately 40,000 years ago to recent days were discovered. We found shell tools containing the world oldest fishhook, stone artifacts, animal remains, and human bones from the palaeolithic layers of the Sakitari-do cave site. These are important clue to solve the question about the origin of human culture in Okinawa. In this presentation, I report our new findings at Sakitari-do cave site and discuss the palaeolithic life styles and their chronological change in the Ryukyu archipelago.

    「The Boat as a Living Space: Lianjiachuan Yumin Who Keep Moving on the Water and Living in Settlement-Oriented Society in Southern Fujian, China」
    FUJIKAWA Miyoko
    (Faculty of Humanities, Nanzan University)

     The nomadic people in the world have been pressured to settle down in a particular place by the emergence of the modern nation-state. In fact, for boat dwellers, what does it mean to acquire a house on land? Does it mean, as many researchers and government officials in modern countries have assumed, a departure from the “harsh world on the water” to salvation on the “enticing world of the land”? Through presenting an ethnographic study of the history of the lianjiachuan yumin (連家船漁民) living on the sea or rivers in the southern part of Fujian Province, China, this presentation aims to explore the reasoning behind their way of life, which cannot be simply reduced to a one-sided move away from a nomadic life on water to settlement on land.

    「Introduction of Vegetation in Northern Sumatra, Indonesia」
    SUZUKI Eizi
    (International Center for Island Studies, Kagoshima University)

     Northern part of Sumatra Island has still rather wide area of primitive tropical rain forest though most areas of Indonesia have lost forests. The area is also famous for rich fauna, elephant, orang hutan, tiger, etc. I visited Geumpang―Pameu area of Aceh Province, located at the northern end of Sumatra Island in 2009, and Tangkahan area of Gunung Leuser National Park, North Sumatra Province in 2014 and 2015. I will show you the vegetation in these areas at this seminar.

    「The Characteristics of Sakitsu Village in Amakusa as One of the 12 Components of the World Cultural Heritage “Hidden Christian Sites in the Nagasaki Region”」
    NAKAYAMA Kei
    (Cultural Division, Tourism and Culture Department, Amakusa City)

     The “Hidden Christian Sites in the Nagasaki Region”, which was registered on July 2018 by United Nations Educational, Scientific and Cultural Organization (UNESCO), is a serial property comprising 12 components, made up of ten villages, one castle remains, and one cathedral dating from between the 17th and 19th centuries. They reflect the era of prohibition of the Christian faith, as well as the revitalization of Christian communities after the official lifting of the prohibition in 1873. Among the 12 components, Hidden Christians in Sakitsu Village in Amakusa continued their religious faith in a unique way, substituting everyday items that were used in their daily life and work in the fishing village for Christian devotional tools during the ban on Christianity, which significantly contributed to demonstrating the property’s exceptional significance (OUV: Outstanding Universal Value) of the heritage.
     In this study, after introducing a brief overview of “Hidden Christian Sites in the Nagasaki Region”, I would like to explain 1) the way of conservation based on the Law for the Protection of Cultural Properties, i.e., the characteristics of the Cultural Landscape of Sakitsu-Imatomi as “important cultural landscapes” selected by the Agency for Cultural Affairs and 2) the way to verify the tradition of Hidden Christians for contributing to OUV.

    「Dental Practice in Remote Islands」
    TAGUCHI Norihiro
     (Graduate School of Medical and Dental Sciences, Kagoshima University)

     In the past, major dental diseases have been caries and periodontitis. In Japan, the rate of suffering caries has been gradually decreasing, and most of Japanese people have got to pay attention to their oral health. However, in Kagoshima Prefecture, an infant’s rate of suffering caries is still high. Kagoshima Prefecture also has a large population in remote islands and a high aging rate, so a unique strategy in a dental practice supply system is needed. One of them should be “Patrol dental practice in remote islands”, which Kagoshima dental association carries out, supported by Kagoshima Prefecture. In this project, a dental professional team visits remote islands that do not have dentists and serves a dental practice for a few days almost two times per year. Kagoshima University Hospital also has been sending dentists and totally support to this project for decades.
     In this presentation, I will show dental problems in Kagoshima Prefecture and the dental practice supply system in remote islands. Moreover, I will introduce our activities (related to the curriculum reform of Faculty of Dentistry, Kagoshima University, in 2015) for contributing to the development of the local community.

    「Why do mites and ticks have the most number of valid species in terrestrial arthropods excepted insects?」
    SHIMANO Satoshi
     (Science Research Center, Hosei University)

     The taxon-group of Acari has most number of valid species (almost 55,000) in Arachnida, however Acari was disappeared in textbooks of invertebrate nowadays. Acariformes and Parasitiformes sensu lato are used as separated taxon-groups instead of Acari. Although two-name system, tick (sucking blood) and mite (others) were common for meaning Acari in some countries, Japanese use one word “dani” for Acari. French use three categories, tick, mite and ciron (ceron). The “ciron” means cheese mites (and some small bugs) and was used as the symbol of minimums in some French literature (e.g. Fables by Jean de la Fontaine in 1668, Pensées by Blaise Pascal in 1670). Acarine species are recorded almost 2,000 in Japan, and 1% (almost 20 species) of them are harmful as common sucking blood ticks. Acari have diverse eating habits, while other members of Arachnida are only predators. The diversity of Acarine eating habits may have maintained species diversity of them. Oribatida as a decomposer has various physical appearance. The much morphological diversity is a strategy to defend against predators. The oribatid mite have not only morphological defense but also chemical defense as chemical secretion from opisthonotal glands and physical defense as jumping. These various defense strategies are also helpful in maintaining diverse species.
