We investigated the characteristics of the thermohaline structure and phytoplankton community from the southwestern areas of Jeju to the nothern areas of Taiwan in the Ease China Sea, in June 2004. According to the analysis of a T-S diagram, three characteristic of water masses were identified. We classified them into the mixed water mass by the Chiness continental coastal waters and Yellow Sea cold water (Region A), Chinese continental coastal waters (Region B) and Taiwan warm current (Region C). Region A was characterized by low temperature, low salinity, high density and high Chl-a concentration. Region B was characterized by high temperature, low salinity, low density and high Chl-a and Region C was characterized high temperature, high salinity, low density and low Chl-a concentration. The phytoplankton community identified a total of 56 species belonging to 31 genera. The dominant species was mainly dinoflagellates, Gymnodinium breve, Scrippsiella trochoidea, Ceratium fusus, Prororcentrum triestinum, centric diatoms, Chaetoceros lorenzianus, Leptocylindrus danicus, Proboscia alata, Skeletonema costatum and pennate diatoms, Pseudonitzschia pungens, Cylidrotheca closterium. Standing crops of phytoplakton fluctuated between 0.1×102 cells/L and 5.7×104 cells/L by dominance of dinoflagellates. In the phytoplankton community, the Region A was characterized by the various species composition in 39 species, the dominint species with di-atomes, Pn. pungen, Ch. lorenzianus and standing crops from 6.9 cells/ml to 56.6 cells/ml, Region B by the various species composition in 37 species, the dominant species with dinoflagellates, G.breve, S. trochoidea and standing crops from 4.6 cells/ml to 26.7 cells/ml, and the Region C by low species number with 28 species, the dominant species with one dinoflagellate, S.trochoidea and one diatom, L.danicus and very low standing crops from 0.1 cells/ml to 5.7 cells/ml. Phytoplankton productivity in the East China Sea was controlled by Chinese continental coastal waters which include a high concentrations of nutrients.
Historical study of Korean traditional houses have been carried, mainly, based on the geographical region of Korean peninsula. However, the case of primitive houses can not be researched according to the geographical and racial concept of modern nations. This study aims to examine the primitive houses of ethnic minorities of northeastern China, where the cultural and racial background have been deeply rooted in the history of Korea as well as Korean traditional houses. Through the field research and literary materials, the basic types of primitive houses of the five ethnic minorities could be identified. Among these types, those that have possible relationship with Korean houses, are cone shaped house, underground house, and elevated wooden house. Archeological evidences of underground houses were amply found in Korea already, but above ground evidences could not be found. However, It seems quite certain that the cone shaped houses and elevated wooden houses, too, existed in Korea as one of the earliest housing types, as can be examined in remaining examples in Korean peninsula. With no doubt, the primitive houses of Korea have strong connection with that of the ethnic minorities of northeastern China. This can be verified through the facts that the evidences of cone shaped houses, the similarities of the use of Inner space, the evidences of elevated wooden houses. Also, the combination of wooden floor and ondol, which is known to be one of the strongest characteristic of Korean traditional houses, could be originated from the combination of primitive summer house, the elevated wooden house, and the winter house, the underground house with ondol.
This study is focused on a space for man in upper classes house that is one of appeared characteristics as Korea, China and Japan imported Confucianism become common cultural base in these countries. Because a space for man in these countries has the same nature represented as a typical space in a upper classes house, and this space is differentiated by regional features, a way of thinking, a way of life and social structure as well, these characteristics are compared one another. Import of Confucianism influenced formation of a upper classes house and the spaces of the house are divided by generation, sexuality and classes. A space for man become a center of the house as well as a space for reception in accordance with patriarchism because this space stands for hierarchy of the house. A space for man of each country, Korea, China and Japan, has differences; that is, Chinese Jeongbang is used as a space for family as well as for guests; Korean Sarangchae is for only men and used as a reception space; Japanese Zasiki is used just for reception. These differences among countries are caused by owner's class, a civil officer or a military officer, and this class differentiated the characteristics of reception for guest. Even though the these countries take the space for man for meeting, Chinese is for family, Korean is for ancestors and Japanese is for guests.
2000-2004년에 걸쳐 수행된 장백산의 나방류 조사결과로 Plusiinae 아과 34종이 분류, 동정되었다. 그들 중 Abrostola ussurienis Dufay, Polychrysia aurata (Staudinger), P. splendida (Butler), Lamprotes mikadina (Butler), Autographa amurica (Staudinger), A. v-minus (Oberthur) 등 6종이 중국미기록 종으로 밝혀졌다. 과거에 보고되었던 Antoculeora ornatissima (Walker), Autographa nigrisigna (Walker), 그리고 Syngrapha hochenwarthi (Hochenwarth)등 3종은 본 조사에서 발견되지 않았다. 새로이 밝혀진 중국 미기록 6종에 대해 성충의 외부특징에 대한 간략한 기술과 그들의 암수생식기를 도해하였다. 장백산에서 보고된 총 37종의 목록을 제시하였다.
무분별하고 과도한 자연의 개발로 비롯된 대규모적인 생태계의 훼손은 매우 중요한 해결과제이다. 열대 및 아열대지역은 지구상에서 수많은 생물종이 탄생하고 자라난 요람지로서 이지역의 훼손된 생태계 연구는 많은 학자의 관심을 보이고 있다. 중국의 열대 및 아열대지역의 훼손된 생태계 복원에 관한 연구결과를 유역생태계. 습지생태계, 폐탄광지 생태계, 산지생태계 분야로 나누어 리뷰하였다. 그리고 최근 몇 년간 중국의 열대 및 아열대지역의 훼손된 생태계 복원에 관한 대표적인 성공 사례를 소개하였다.
