宋浚任 梨花女子大學校 韓國生活科學硏究院 1985 韓國生活科學硏究院 論叢 Vol.36 No.-

본 연구는 月城원자력발전소와, 舒川화력발전소의 취수구에 1984년 10월초 실험부착판을 설치하여 1985년 6월까지 附着動物의 種 組成과 郡集生態를 조사하였다. 조사결과, 附着動物은 月城에서 8門 10綱 17目 43科 70種으로 Mytilus, Balanus와 단체해초류의 부착이 현저하고, 舒川에서는 10門 14綱 20目 48科 62種으로 말미잘類, Chlamys, 군체해초류와 端脚類 접관의 부착이 현저하다. 月別에 따른 변화를 보면 月城에서는 초기단계의 粘性被膜이 점점 두꺼워지고, 새로운 附着動物群의 출현이 빠르지만, 舒川에서는 초기단계의 端脚類 棲管이 점점 두껍게 형성되면서 付着動物群의 출현은 늦다. 附着動物을 형태학적 특징에 따라 類型으로 보면 다음과 같은 천이과정을 알 수 있다. 月城 : CcS→Mssv=Mslf→Mtl→Mslv=Mssf 舒川 : Mts,Ccs→Mssv=Mtl→Mslf=Cct→Mslv=Mssf 舒川은 月城보다 늦은 속도로 遷移되고 있으며 최종적인 優占種은 Mytilus edulis(Mslv)일 것으로 본다. 본 연구는 韓國科學技術院 化學硏究所 硏究事業의 일환으로 수행되었으며, 조사과정 동안 도움을 주신 韓國科學技術院 化學硏究所 分析室長 김풍작 博士님과 그 室員, 韓國電力公社 拉術硏究院 김은아部長님 과 송영문科長님께 謝意를 表한다. To understand the changes of the species composition and the morphology of fouling animals community, a series of studies were carried out at the intake of Wolso˘ng Nuclear Power Plant and So˘ch'o˘n Thermal Power Plant from October, 1984 to June 1985. As a result, 70 species, 43 families, 17 orders, ten classes in eight phyla at Wolso˘ng, and 62 species, 48 families, 20 orders, 14 classes in ten phyla at So˘ch'o˘n were observed during the studv period. Some outstanding group of animals were Wytilus, Balanus and solitary ascidians at Wolso˘ng, and Chlamys, sea anemones, compound ascidians and tubes of amphipods at So˘ch'o˘n. The changes cf species were appeared to be early at Wolso˘ng, eastern coast of Korea. Therefore, it seems the last dominant species of fouling animals is Mytilus edulis.

The aim of this study is to find out the relationships between the microstructures of SM45C(AIS11045) steel and fatigue crack propagation behaviour. Three microstructures such as (ⅰ) as received (fully annealed). (ⅱ) water quenched and tempered, and (ⅲ) ail quenched and tempered were used for fundamental mechanical testing and fatigue crack proagation test. The microstructures of (ⅱ) and (ⅲ) showed superior in tensile strength to (ⅰ). Resistance against fatigue crack propagation was higher in structure (ⅰ), while tensile properties were better in structures(ⅱ) and (ⅲ). It is believed due to that the enhancement of roughness of fracture surface obsered in structure (ⅰ) increases ?Kth and lowers fatigue crack growth rate. However it does not necessarily mean the quenched and tempered structures (ⅱ) and (ⅲ) are undesirable for the engineering component because fatigue limit in low cycle test appears usually higher in the microstructures of higher strength.

한국 동해연안의 하나인 온산만 지역의 해양오염 실태를 파악하기 위해 저서동물 군집구조에 대한 정성, 정량적 분석을 실시하였다. 분석결과 조사지역별 습중량-개체수의 누적 κ-dominance curve 변화양상을 근거로 판단해 분석한 결과, 온산만의 내만에 위치한 춘도는 여름, 겨울 오후에 ()어서 오염지역으로, 대조군인 당사는 비오염지역,()각각 판정되었다. 이외에도 조사지역별 출현() () 있어서 대조구인 당사지역에 비해 춘도의 생물상이 ()대적으로 빈약하였으며 연체류중 패각만 채집된 ()에 있어서도 각각 춘도에서 16종, 당사에서는 (0로 커다란 차이를 나타내었다. 온산만에 대한 이러한 저서동물 군집결과는 이 주변의 비철금속 및 석유화학 공업단지로부터 ()입된 중금속으로 인하여 해수 및 생물농축량이 누적됨으로써 나타나는 중금속의 높은 농도와 관련이 있을 것으로 추측된다. The qualitative and quantitative analyses of macrozoobenthic communities sampled from Onsan bay of the eastern coast of Korea were conducted, in this study, to investigate the status of marine pollution. In each survey site, judging from the results of the combined κ-dominance curve for species biomass and individual numbers, it may be assessed that Chundo island, located in innerside of Onsan bay, was in the state of polluted condition both in the summar and winter seasons; on the other hand, Tangsa, the control site of this study, was in the state of unpolluted condition. The species composition of the Chundo island, in addition, was rather lower than that of the Tangsa in richness and showed critical differences with the control site in the number of molluscan species collected as dead shell(16 spp. from Chundo island; 2spp. from Tangsa respectively) It is inferred that the resultant macrozoobenthic community structure of the Onsan bay was related to the high concentration of heavy metals in seawater and bioaccumulation, attributed to the influx of the heavy metals from the surroundings, the nonferrous and the petrochemical industrial complex.

Geographic Variation of Granulilittorina exigua (Littorinidae, Gastropoda) in Korea Based on the Mitochondrial Cytochrome b Gene Sequence

Song, Jun-Im,Suh, Jae-Hwa,Kim, Sook-Jung The Korean Society for Integrative Biology 2000 Korean journal of biological sciences Vol.4 No.3

Partial sequence of the mitochondrial cytochrome b gene was analyzed to investigate genetic variation from 10 geographic populations of Granulilittorina exigua in Korea. The sequence of 282 base pairs was determined by PCR-directed silver sequencing method. The sequences of two species within the genus Littorina reserved in NIH blast search were utilized to determine geographic variations of species referred. The levels of mtDNA sequence differences were 0.00-2.54% within populations and 0.71-4.43% between populations. There were four amino acid differences between representative species of the genera Granulilittorina and Littorina, but no differences within populations of the genus Granulilittorina. The UPGMA and the N-J trees based on Tamura-Nei genetic distance matrix were constructed, which showed that the genus Granulilittorina was divided into three groups such as eastern (even exception for Tokdo population), southern, and western regional populations. The degrees of genetic divergence within populations of each group were p=0.021, p=0.019, and p=0.018, respectively. The divergence between the eastern and southern populations was p=0.032, showing closer relationship than with the western populations (p=0.052). Based on the diverged time estimation, the eastern and southern populations of Granulilittorina exigua in Korea diverged from the western populations about 2.1 MYBP, and the eastern and southern populations diverged from each other about 1.3 MYBP.

한국산 산호충류 중 돌산호류의 계통분류학적 연구를 하기 위하여 1969년부터 1986년까지 우리나라의 삼면연안과 도시지방(35개 지역)으로부터 채집된 표본들을 동정 분류하고 지리적 분포도 고찰하였다. 그 결과 5아목 7과 15속 24종이 밝혀졌으며 이 중에서 7종은 한국미기록종이었다. 한국산 돌산호류를 분포형으로 보면 열대형(16종, 66.7%)과 온대형(8종 33.3%)으로만 되어있고, 해역별로 보면 제주도 해역에 16종(4온대종, 12열대종)으로 가장 많은 종이 분포하였으며 황해에 3종(2온대종, 1열대종)으로 가장 적은 종이 분포하였다. 해역간 유사계수를 근거로 보면 대한해협과 동해 사이의 유사성(0.596)이 가장 크고, 황해와 제주도해역 사이의 유사성(0)은 전혀 없었다. The stony corals known from Korean waters are 24 species, 15 genera, 7 families in 5 suborders , of which 7 species are newly recorded to the Korean scleractinian fauna: Montipora trabeculata, Oulangia stokesiana miltoni, Goniocorella dumosa, Dendrophyllia arbuscula, D. boschmai cyathohelioides, D. micranthus, and Rhizopsammia minuta mutsuensis. they were collected from 35 localities of southern Korea from 1969 to 1986. For the geographical analysis, the coastal waters of Korea are divided into four regions: the Yellow Sea, the Korea Strait, the Cheju Island area and the East Sea(Sea of Japan). These are based on the species diversity, the geographical distribution form, and the community coefficient. Korean scleractinians consist of 8 temperate zone forms (33.3%,Te)and 16 tropical forms (66.7%,Tr). Concerning the distribution in each region, 3 spp. (2Te,1Tr)occur in the Yellow Sea, 9 spp.(5Te,4Tr)in the Korea Strait, 16 community coefficient between the Korea Strait and the East is the highest(0.596), and that between the Yellow Sea and the Cheju Island areas is the lowest(0).
