한국 특산종 Cobitis longicorpus (왕종개)의 주요 분류형질인 골절반의 지리적 변이를 조사하기 위하여 남한의 12개집단 205개체를 이용, 골질반의 type분석과 계수학분석을 실시하였다. Type분석 결과, 동해유입하천집단(영덕의 송천, 축산천, 경주 형산강, 울주 회야강)의 골질반은 등근 삼각형, 삼각형, 인각형으로 남해 유입하천 및 도서집단의 타원형, 반타원형, 부채꼴과 구별되었다. 골질반의 계수화분석 결과에서도 동해유입하천의 골질반 폭은 비교적 좁아 남해유입하천 및 도서지방과의 평균 CD값이 1.64로 새종 수준 이상의 차이를 보였다. 아울러 조사, 비교된 제 1 체측반문도 동해유입하천에서는 C. longicorpus의 특징이 전혀 나타나지 않아, 원기재질단인 섬진강집단을 포함한 남해유입하천 및 도서집단과 구별된 새종수준의 종분화가 이루어진 것으로 사료되었다.

국내에서 널리 쓰이고 있는 각종 농후사료에 대한 일반성분 및 Ca, P함량을 분석했고 또 비타민, 광물질, 아미노산 함량을 분석하기 위하여 46종의 사료에 대한 대표 시료를 분석했던 바 그 결과는 다음과 같다. 1. 옥수수, 밀, 소맥쇄, 미강(抽), 밀기울, 대두박(抽), 아마박(抽), 옥수수글루텐밀, 임박(抽), 채종박(抽), 호마박(抽), 골분, 어분(국산 및 외산), 패분등이 가장 수집빈도가 높았으며 대개의 경우 일반성분 분석치에 있어서는 미국 또는 일본의 그것과 큰 차이는 없었으나 분석시료 내용이 다른 경우에는 같은 사료라도 변이가 심하였다. 2. 분석치에 있어서 같은 사료라 할지라도 함량변이가 큰 것이 많았는데(말분, 소맥쇄, 맥강미강, 박류, 골분, 어분, 패분등) 이것은 수집된 샘플이 동일하지 않았고, 같은 사료라도 물리적 성상이 다르거나(말분등), 이 물의 혼입등<골분, 어분, 박류등>이 있었기 때문인 듯하다. 3. 선발된 46종 사료의 대표 샘플에 대하여 비타민, 광물질, 아미노산함량을 분석했던 결과를 보고하였으나 이것이 단 1회의 분석이었다는 점, 또는 어떤 성분은 분석이 안되었다는 점을 고려하여 장차의 보완 작업에 기대는 거는 바이다.

These studies were carried out to develop native Calanthe in Korea. Calanthe native to southern islands in korea has beautiful flowers with various color and sweet fragrance, and it has been reported to have very good ornamental value. Concerning the classified 57 lines had surveyed their characteristics during the three years, and confirmed which that had manifestation stably. And then, a line was developed and given a name of horticultural cultivar to ‘Saegdong’. The major characteristics of the selected line, ‘Saegdong’, were as follows. In its color of flower, sepal was reddish orange, petal was yellow and lip was yellow. ‘Saegdong’ had a bended-inner blooming type.

Micro-algae are unicellular photosynthetic organisms and produce pigments such as chlorophyll and carotenoid. Chlorella contains a lot of protein and functional components like lipids, chlorophyll and carotenoids. In this study we induced mutants of Chlorella vulgaris (C. vulgaris) through ultraviolet radiation (UV-B) and selected two mutants by pigment (chlorophyll and carotenoids) content. We named the mutants ‘UBM1-2’, ‘UBM2-57’ and they were cultivated for 21-days. Cell growth, dry cell weight, protein content, lipid and pigments content were measured. The results indicated that the mutants displayed slower cell growth, lower dry cell weight and protein content than the wild type. However, for UBM1-2 the lipid content was 21% higher than the wild type. In addition, the mutants’ chlorophyll content was 37% and 89% higher than the wild type and the carotenoids content was 27% and 70% higher than the wild type, respectively.

Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.

Beta diversity is an efficient means of assessing the spatial variation in community composition among sites. To present fish community variation and LCBD (Local Contribution to Beta Diversity) among sites in stream, 6 sampling sites were selected in Cheonggye stream. Fish communities, environmental and habitat variables were collected at sites from April 2014 to October 2015. We used the total variance of the fish community data table (site-by-species community table) based on different forms, presence-absence, abundance, and Hellinger transformation, to estimate and compare beta diversity and LCBD. Fish community data table transformed by Hellinger distance showed the higher values of beta diversity than presence-absence and abundance data table. A similar patterns of LCBD were observed with presence-absence and Hellinger transformed data table. Low value of beta diversity calculated by community data table with abundance was due to the non-normality of fish assemblage data. Additionally, correlation coefficients were calculated to evaluate the relationships among LCBD, community indices and physicochemical variables. LCBD showed negative correlation coefficients with Shannon diversity. Overall, application of beta diversity analysis is an efficient method of addressing spatial variation of fish communities and ecological uniqueness of the sites in stream.
