This study was carried out to investigate meat production ability of special poultry(Ogol fowl, pheasant and mallard). The results obtained Were summarized as follows ; 1. On the average live weight in male and female of Ogol fowl and mallard were 1,304.0~1,311.8g, 1,013.0~1,138.8g, respectively. The live weight of pheasant was lighter than that of Ogol fowl and mallard. The ratio of carcass to live weight in pheasant, Ogol fowl and mallard were 70.9~72.2%, 66.9~68.2% and 65.4~65.9%, respectively. 2. On the edible giblets ratio to live weight, the that of mallard was the highest(6.3%), while the that of Ogol fowl was the lowest(4.7~4.8%) in each individual poultry. 3. On the cut-up parts ratio to carcass weight, the neck(6.7~8.3%) and back(16.1~18.0%) ratio of pheasant were lower than that of Ogol fowl and mallard, but the neck(11.1~13.3%), wings(14.6~16.2%) and back(23.6~5.2%) ratio of mallard were higher than the others. 4. On the ratio of meat to breast and legs parts, the yield of breast meat was higher than that of legs meat of all poultries. In mallard, the skin ratio on both parts(17.6~22.9%) was higher than the others, while the bone ratio of pheasant and Ogol fowl(15.6~20.6) was higher than that of mallard.

This research conducted a survey on waterbirds visiting this area four times by season from February to October in 2007 to look into the habitat use of waterbirds, to do a value and grade testing of the tidal flat by dividing the foreshore on Muan Bay located in Jeollanam-do into four areas (Dongam, Guro, Bokryong and Wangsan tidal flats). The survey results revealed that there existed a total of 15,755 individuals of 54 species including 2 species of grebes, 7 species of herons, 7 species of dabbling ducks, 6 species of diving ducks, 20 species of waders, 3 species of gulls and 9 other species and this survey also observed 9,291 individuals of the wading birds as a dominant group on Muan Bay. In these classified groups, the gulls and waders were observed to mostly use Dongam tidal flat as their habitat, while the group using Guro tidal flat as their habitat was mostly grebes, dabbling and diving ducks. As a result of UPGMA clustering analysis in consideration of the species and number of individuals, there appear the close similarities between Dongam and Bokryong tidal flats and so do Guro and Wangsan tidal flats. Taking a look at the grading of tidal flats by setting up ecological indexes, such as diversity index, abundance index, and dominance index, etc. legally reserved species and maximum number of individuals as a standard, the rank for the value and importance degree of Bokryong tidal flat appeared higher than that of the other three tidal flats. Like this, the gradation of tidal flats according to waterbirds are judged to able to suggest objective data on the issue of proper judgment and designation of valuable tidal flat areas and its subsequent effective preservation and management.

For research of the wintering waterbirds we surveyed monthly from October 2000 to March 2001 on Gangjin Bay, Chollanam-do, Korea. During the study period, the waterbirds were observed 9,825 individuals and 36 species. The highest dominant species was Anaspiatyrhynchos which occupied the $48.42\%$, the one followings were Anas crecca $(10.8\%)$, Tadorna tadorna $(9.7\%)$, Anas poecilorhyncha $(9.5\%)$ and Cygnus cygnus $(4.8\%)$. A regularly observed species in every months were 3 species, Egretta garzetta, Anas pin tyrhynchos and Anas poecilorhyncha. The Cygnus cygnus of specially protected species was observed the 232 individuals maximumly in November and the 125 individuals to a minimum in December. The index of species diversity was minimum 1.24 at October and maximum 2.01 at March. This area has provided a suitable roosting and feeding place for waterbirds. The peak count of the wintering whooper swan was 232 individuals in Gangjin Bay. Therefore, We need the conservation and management of Gangjiun Bay.

The identification of volatile constituents in foods is important in creating flavor compounds to improve the flavor of foods. This study was conducted to identify the flavor compounds in soybean sprouts cultivated with 4 different types of soybean seeds. A total of 52 flavor compounds were identified and composed mainly of alcohols (16), aldehydes (17), ketones (10), acids (2), furans (2), and miscellaneous compounds (5). Sprouts cultivated with Dawonkong and Orialtae showed 46 flavor compounds whereas Pungsannamulkong and Nokchaekong was 49 and 50. In total flavor compounds contents, Orialtae was the highest (19.3 mg/kg RC) and followed by Pungsannamulkong (15.83 mg/kg RC), Dawonkong (13.2 mg/kg RC), and Nokchaekong (11.3 mg/kg RC) in that order. Two groups including alcohols and aldehydes were detected high amounts in which their ratio were analyzed 32% and 51% in total flavor contents, respectively. It may be responsible for flavor in soybean sprouts. In case each flavor compound content, 2-hydroxybenzaldehyde was detected the major compound and hexanol, 1-octen-3-ol, and hexanal that the main compounds in lipid oxidation of soybean products were identified the main volatile flavor compounds in soybean sprouts.

가금콜레라(Fowl Cholera)는 야생조류와 닭$\cdot$오리에서 급성 패혈증을 일으키고, 부검시 복강내 실질장기(심장, 근위, 십이지장)에서의 출혈을 일으킨다. 특히, 이 질병은 간의 다발성 괴사반점을 보이고 때로는 신경증상을 나타내는 것을 특징으로 하는 세균성 질병으로 제 2종 법정 가축전염병에 속한다. 국내에서는 지난해인 2000년 10월 22일부터 충청남도 서산시 소재의 천수만 간척지에서 야생조류의 집단 폐사가 발생했다. 그래서 국립수의과학검역원 조류질병과에서 현지 역학조사와 실험실 정밀검사를 통해 처음으로 폐사 원인을 가금콜레라로 진단 내렸다. 그 당시 본 질병으로 폐사한 야생조류는 대부분 오리류(가창오리, 청둥오리 등)였으며 총 13,000여수가 폐사 되었던 것으로 공식 집계되었다. 현재까지 국내에는 검역원 및 일선 시도 가축방역기관들의 철저한 방역조치와 함께 가금 사육농가의 위생적인 사양관리 등으로 닭이나 집오리에서의 가금콜레라는 발생되지 않고 있다.

One hundred fifty six pieces of woods were excavated at the muddy sand layer (post-glacial age: about 8,800 bp) above the upper peat layer from Sarori, Chungwongun, Korea in the central Korea. Due to the deteriorated structure of peat woods, all samples were embedded in PEG(polyethylene glycol) 2000 and then sectioned using a rotary microtome. Only two species were found; Alnus spp.(95%) and Ulmus spp.(5%). No conifers were found. Species composition indicates that the climate condition of central Korean peninsula around 8,800 bp was little wetter condition. The sampled region at the Sarori appeared to be a swamp or riverside.

This study was carried out on Sihwa reclaimed area from January to December in 2003. We observed total 169,351 individuals of 70 species(22 species of waders, 9 species of egrets and 5 species of gulls). Waterbird population was the largest in March(95,465 individuals) and was the smallest from April to June(less than 7,000 individuals). The most dominant species was Pintail(Anas acuta: 58,627 individuals, 34.6%) and other species were Mallards(Anas platyrhynchos: 24.5%), Common Pochards(Aythya ferina: 13.8%), Black-tailed Gulls(Larus crassirostris: 6.1%), Spotbill Ducks(Anas poecilorhyncha: 5.0%) and Greater Scaups(Aythya marila: 2.69%). Sihwa reclaimed area supported many kinds of protected species such as Chinese egrets(Egretta eulophotes), Black-faced Spoonbills(Platalea minor), Eurasian Spoonbills(Platalea leucorodia), Mute Swans(Cygnus olor), Whooper Swans(Cygnus cygnus), and Eurasian Oystercatchers(Haematopus ostralegus). They foraged at waterside of Sihwa lake and rested at reclaimed area. Particularly, Eurasian Oystercatchers bred in habitats with Salicornia herbacea and Suaeda japonica. Reclamation of mud flats and construction of roads, transmission towers and tide embankments disturbed waterbirds in breeding and foraging. We suggest that waterbirds are protected in different action plans according to their status such as breeding, passaging and wintering birds. Maintaining of waterside and swamps in Sihwa reclaimed area will be useful for breeding waterbirds. It is needed to make a protect zone for ecological connecting belt from Oeji isarea, Hyeong isarea, Eum isarea to upper channel on Sihwa lake.
