The Korean government has recently announced its plan to establish the first National Museum of Natural History. However, the Korean word for natural history, jayonsa, is not a very familiar term to some academics as well as the general public. This article discusses the definition and history of natural history, describes the functions of natural history meseums, and makes suggestions to the establishment of our National Museum. Modern natural history is no longer an art of ‘stamp collecting’. It is a comprehensive scientific endeavor pursuing to enlighten the history of the planet Earth and the diversity of natural objects it contains. Natural history museum must have two museums within the museum: the outer museum for exhibition and general public education and the inner museum for research and specialist education. I hope that our National Museum of Natural History will be a place where we all get to know about Nature and thus to love her.

This work discussed the species composition, phylogeny, spatio-temporal distribution, ecology and natural history of North Korean Pinaceae or pine tree family, which seems to be important to maintain nature and ecosystem in the Korean Peninsula. Out of five genera and sixteen species of Pinaceae of the Korean Peninsula, North Korea contains four genera and eleven species of Pinaceae, including Pinus densilflora, P. koraiensis, P. pumila, Picea jezoensis, P. koraiensis, P. koraiensis var. koraiensis, P. pungsanensis, Larix gmelini, L. gmelinii var. olgensis, Abies holophylla and A. nephrolepis. In terms of phylogeny Pinus is closely related to Picea, and followed by Larix. Abies is close to Tsuga which only occur at Ullung Island. Distributional pattern of North Korean Pinaceae can be classified into four types; three species of nation-wide montane type i.e., Pinus densilflora, P. koraiensis and Abies holophylla, four species of central and northern subalpine type, i.e., Pinus pumila, Picea koraiensis, Larix gmelini and Abies nephrolepis, one nation-wide subalpine type, Picea jezoensis, and three species disjunctive to north type, i.e., Picea koraiensis var. koraiensis, P. pungsanensis, and Larix gmelinii var. olgensis. Pinaceae species occurring on the alpine and subalpine belts of North Korea, such as Pinus koraiensis, P. pumila, Picea jezoensis, P. koraiensis, P. koraiensis var. koraiensis, P. pungsanensis, Larix gmelini, L. gmelinii var. olgensis and A. nephrolepis are considered as the glacial descendant from the boreal region. Those species might have migrated from the north during the Pleistocene glacial epochs in search of favourable condition, and since the Holocene period they survived on the hostile alpine and subalpine environments, in which they are more competitive than warmth-tolerant temperate vegetation. Certain species, such as Picea pungsanensis, is segregated on the isolated mountains since the Pleistocene period, and forced to adapt to local environment, and eventually became an endemic species of North Korea. Recent rapid global warming trend especially in northern high mountains of North Korea could cause an unfavourable environment for the survival of cold-tolerant Pinaceae of the alpine and subalpine belts. Pinus densiflora, which is occurring on the montane belt might faced with difficulties due to both the deforestation and the outbreak of insect-borne disease, such as Bursaphelenchus xylophilus.

Cooperative behavior may seem contrary to the notion of natural selection and adaptation, but is widely observed in nature, from the genetic level to the organism. The origin and persistence of cooperative behavior has long been a mystery to scientists studying evolution and ecology. One of the important research topics in the field of evolutionary ecology and behavioral ecology is to find out why cooperation is maintained over time. In this paper we take a historical overview of mathematical models representing cooperative relationships from the perspective of mathematical biology, which studies population dynamics between interacting biological groups, and analyze the mathematical characteristics and meanings of these cooperative models.

Psalidoremus is one of the subgenus which consists of five species and eleven subspecies through Taiwan, Japan, Korea and north eastern part of China which present strong endemism to their distribution. While most of advance studies focus on the new species or subspecies from this taxon, this paper suggests paleogeographical assumption and hypothesis of how they diverged from common ancestors. Phylogeographical patterns illustrated by the distribution of five species, which including Prosopocoilus inclinatus, Prosopocoilus hachijoensis, Prosopocoilus dissimilis, Prospocoilus pseudodissimilis, Prosopocoilus motschulskii respectively, has been assessed in this research. Speciation history is suggested by morphological tendencies especially in male mandibles with assumption from geographical patterns of under sea level.

The sicence of ecology was introduced into Korea as a part of biology translated into Chinese or Korean from western biology textbooks imported by way of China or directly from the West at the end of 19th c. to the beginning of 20th c. After the Japanese annexation of Korea in 1910, Japanese technologists had studied applied ecology to exploit the natural resources of Korea. Reforestation, begetation eclogy, riparian vegetation, etc. were investigated by workers from the West. Such ecological researches, however, did not contribute to the introduction of ecology into Korea, and the anture of the Korean peninsula was utilized by foreign ecologists as ecological research sites. Several Korean ecologists, not many, worked actively at the end of Japanese rule, and contributed to the settlement ecology in Korea since 1945.

This paper describes the role of ethnoecology in supporting tourism. We conducted a case study on the island of Bali (Indonesia), the famous tourism destination. We review the culture, nature and ecotourism prospects of Bali and then extend our discussion to examine the role of indigenous philosophies in building the destination’s image. Bali has a rich culture and natural resources that have been utilized and managed through an indigenous philosophy called Tri Hita Karana. Ethnoecology is widely applied and appreciated in the society and has produced Balinese cultural landscapes that have become significant tourism attractions. There has been a recent increase in tourist desire to explore genuine Balinese culture, so ethnoecology has a significant role in the quest to preserve and conserve such indigenous cultural landscapes. Ethnoecology is a key to ensuring and sustaining the images and authenticity of Bali Island. In this paper, we considered the landscape of rice paddies as a cultural landscape and resource for tourism. The structure and function of paddy terrace landscapes is based on the ethnoecology of Tri Hita Karana; therefore, in order to understand nature and ecotourism in Bali Island, knowledge of indigenous philosophy is indispensable. Cultural landscapes that link human and natural systems are not only places of natural beauty but also provide background information about the history of human adaptations to nature.

In this study, 2,238 incidents from History of the Three States, Prehistory of the Three States, History of Koryo, True Records of Chosun Dynasty had been analyzed in order to examine the bathing styles of Koreans. The results were as follows. In the period of Three States, baths were taken for the purposes of cleanness, remedy, and beauty culture as well as etiquettes. And spa, rainwater, rivers, streams, and bath tubs were used. In the period of Koryo, it included not only reasons for etiquettes as in the period of the Three States but also reasons for medical care and daily life. In spa, temples, and homes, baths were taken by using perfumes and towels. In Chosun Dynasty, daily baths were for hygiene, health, and bodily charms. Before religious ceremonies, they made sure that they took baths, and spa baths were popular for the medical care. The ways to take baths included the order which area was the first to be washed, time, and areas concretely, and seasons, weather, and conditions of body were considered before taking baths. Moreover, the places included natural places such as streams, reservoirs, rivers, as well as artificial places such as temples, places for envoys, and palaces. Especially, in spa areas, bathing buildings were constructed. Considering all these, baths were taken for the purposes of ceremonies and medical care in the period of the Three States, and daily baths took down their roots in the period of Koryo. In the period of Chosun Dynasty, spa baths for cures, prays and rituals, hygiene and bodily charms were considered as a reason. How to take baths and means were decided carefully. Therefore, the results above demonstrated that baths took down their roots in people's daily life in Korea since the period of Koryo.
