  • The results identified for bacterial flora 174, Vibrio spp.132, and coliform group 183 strains isolated from the areas of last China Sea and Yosu coastal sea during from August 6th. to 14th. 1992 were as follow: 40 strains among the 74 strains of bacteria flora isolated from fast China sea area were Pseudomonas spp.$(54\%)$ and 60 strains among the 100 strains isolated from Yosu sea area were Enterobacteriaceae $(60\%)$. Four strains were Vibrio alginoliticus and one strain of V, parahaemolyticus among 5 strains of genus Vibrio isolated from last China Sea. While 54 strains were V. alginolyticus $(43\%)$ and V, parahaemolyticus $(17\%)$ among 127 strains genus Vibrio isolated from Yosu coastal sea area. Seventy nine strains among the 156 strains of coliform group isolated from Vosu sea area were Escherichia coli I $(51\%)$ and each one strain Citrobacter freundii I and II. 3 strains among 27 strains isolated from last China sea area were E. coli$(11\%)$ and 1 strain of C. freundii I. Coliform group was grouped into 16 types by IMViC system, $44^{\circ}C$, gelatin liquefaction test.

  • Taking the Yosu Peninsula where prestige goods were prevalent and more dolmen were excavated and surveyed than other regions as object of the research, this dissertation investigated the hierarchy of dolmen society. The dolmen groups were excavated and surveyed at some 20 positions in Yosu Peninsula Analyzing the number, weight of upper stone, location, the buried relics of dolmen, the hierarchy for each dolmen group can be summarized as follows. It seems that the large group with a lot of dolmen and big upper stone which is located on the plane with stream or on the lower part of hill might be the central group with abundant buried relics. However, the size of individual upper stone does not coincide with buried relics sometimes. Thus, it is required to review the entirety of dolmen group rather than individual upper stone in the relation between the scale of upper stone and buried relics. Then the scale of tomb is proportionate to the prestige goods. Meanwhile, the discrepancy between dolmens can be verified by the difference among upper stone, tomb, burial accessories, etc in the unit dolmen group. Since dolmen is the tomb of some inhabitants in the Bronze Age, the existence of stone coffin tomb with buried bronze sword, jade or stone sword compared to the stone coffin with no relics means that there was powerful representative of one generation even in one kindred group on the basis of wealth or authority. It can be concluded that the upper stone or large tomb or prestige goods among the persons buried in dolmen were fixed as high class, those with relatively small stone coffin with no or scanty burial accessories were fixed as medium class and multitudinous class who were not buried in dolmen were fixed as low class. Therefore, the dolmen society in Yosu Peninsula shows that there was division of class in the unit dolmen group as well as hierarchy in the group.

  • The freshwater fish fauna and physical characteristics of streams in Yeosu peninsula and Geumo Islands were surveyed at thirty nine stations in the period of 2003 and 2005. Most of the streams were short in length and narrow in flowing water width. Main materials of riverbed in most stations were cobble, pebble and gravel; those in the stations adjacent river mouth gravel and sand. In the river type, eighteen stations out of surveyed stations were upstream type: Aa. Thirty nine fish species belonging sixteen families were caught in this survey region. Among them twenty seven species were primary freshwater fishes and nine were peripheral. In the species composition of each family, there were the most species in Cyprinidae and Gobiidae, twelve and ten species, respectively. Endemic species of Korean peninsula in this region were eight species. One exotic fish species, Lepomis macrochirus was found in Yeosu peninsula. Dominant species in each district was Zacco temminckii in Yeosu peninsula, Rhinogobius brunneus in Dolsan Island, Leucopsarion petersii in Geumo island and Oryzias latipes in Gae island. In the analysis of community structure, it was appeared that the community of Yeosu peninsula was the most diverse and stable in this region; as the size of island became smaller, diversity and richness of community decreased. Kichulchoia brevifasciata did not caught in this survey, and it is possible that the species was extincted in this island. Acanthorhodeus gracilis and L. petersii were reported firstly in this region.
