한강 중하류의 남조류 및 환경요인의 연간변화 (2000 ${\sim}$ 2003)를 파악하기 위하여, 2000년 4월부터 2003년 10월까지 4년간 성수대교에서 성산대교까지 총 5개 지점을 선정하여, 수계의 기초환경요인 및 식물플랑크톤 현존량 변화를 조사하였다. 조사기간 동안, 남조류의 현존량은 점차적으로 감소하여 장기간 강우가 가장 많았던 2003년에는 거의 관찰되지 않았으며, 총 식물플랑크톤 현존량에 대한 남조류의 기여도는 약 10%범위내였다. 이러한 현상은 매년 강우집중기 동안 팔당댐으로부터 많은 방류수가 유입됨으로서 수온감소는 물론 광량감소, 영양염류 희석 등에 의한 남조류의 성장이 제한된 것으로판단되며, 동일시기에 다른 조류 (녹조, 규조 등)의 높은 성장으로 엽록소 a와 식물플랑크톤 현존량이 뚜렷하게 증가하였다. 따라서 한강 하류의 고온기 동안 남조류 성장은 잦은 강우와 방류에 의해 제한을 받지만 규조나 녹조와 같은 다른 조류들의 높은 성장으로 대치되는 천이현상을 보였으며, 기후영향을 크게 받는 전형적인 하천생태계의 특성을 나타냈다. For 4 years (2000 ${\sim}$ 2003), annual fluctuations of standing crops of cyanobacteria and physicochemical factors were examined at five sites from Bridge of Seungsoo to Bridge of Seungsan in the lower part of Han River. The cyanobacterial abundance (ND to 4,167 cells $mL^{-1}$) was strongly decreased during the heavy rains in every year. During the similar periods in 2003, cyanobacteria hardly observed, and comprised below of 10 percentage of total phytoplankton. In the period of little cyanobacteria, some green algae and diatom dominated the phytoplankton community, while the concentration of chlorophyll a has not largely change. These results indicate that heavy frequent precipitation strongly limited the growth of cyanobacteria, and lead an algal succession by the appearance of new algal groups.

In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter’s activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

Determination of Limiting Nutrient for Algal Growth by Algal Bioassay. Oh, Hee-Mock, Seog June Lee, Seong-Bin Kim, Mi- Kyung Park, Byung-Dae Yoon and Do-Han Kim (Environmental Microbiology Research Unit, Korea Research Institute of Bioscience and Biotechnology, Taejon 305-333, Korea and Water Resources Research Institute, Korea Water Resources Corporation, Taejon 305-390, Korea) Water quaiity and algal growth potential (AGP) using Microcystis aeruginosa were investigated from April to September 1997 in Daechung Reservoir. Secchi disk transparency was 1.1 m in August. Chlorophyll-a concentrations were higher than 10㎍/l at all samples. Total phosphorus concentration was in a range of 0.020∼0.027mg/l which is at the approximate value of 0.03 mg/l, the general critical level of eutrophication. These results indicate that Daechung Reservoir is in an eutrophic state except some temporary times and restricted sites. Phosphorus uptake rate of M. aeruginosa was higher in the water from the epilimnion than in the hypolimnion and also higher under light condition than under dark condition. Therefore, phosphorus uptake rate appears to depend on cellular phosphorous content and light condition, a meaning of endergonic process. Phosphorus was the most frequently limiting nutrient: phosphorus was limiting algal gowth in April and May, nitrogen, phosphorus and trace elements were the limiting factors for algae in August, and trace elements in September. If a fast growing alga, M, aeruginosa, is used as a test organism for assaying AGP, in vivo fluorescence instead of dry weight can be measured for algal biomass and incubation period can be reduced from traditional 14 days to 7 days.

본 연구는 체험적 음악 감상 활동이 발달장애 유아의 신체 표현능력 향상에 미치는 영향을 알아보고자 한 것으로 발달장애 유아의 전인발달 촉진을 위해 일선 특수 교육 현장에서 새로이 시도해 볼 수 있는 음악 감상 활동 프로그램을 제시해 준다는 데 연구의 의의가 있다. 본 연구의 대상은 전남 M시의 한I특수학교 유치부에 재학 중인 발달장애 유아 3명으로 생활연령이 만 4-5세이지만 지능검사 결과 정신연령이 3세 이하의 수준이거나 지시에 순응하지 못하는 정도였다. 다양한 악기와 음악 프로그램을 이용한 체험적 음악 감상 활동을 총 24회기 실시한 결과 체험적 음악 감상 활동은 발달장애 유아의 신체 인식능력, 신체 협응 능력 및 신체 표현 능력의 발달에 효과적이었다. The purpose of this study was to find out the improvement of physical expression ability of young children with developmental disability(CDD) through the experiential music appreciation, which has not been investigated in the special education special research field yet. The experiential music appreciation has been applied to three CDD who attended a special school in M city. Then, the body cognition ability, the physical coordination ability and the physical expression ability were measured, if there were improvement than before. The results are following. First, the experiential music appreciation had an effect on the development of the body cognition ability of CDD. It improved the ability to recognize the names of parts of body, to point parts of their face and body as directed and to name parts of their body. Second, the experiential music appreciation had an effect on the improvement of the physical coordination ability of CDD. It fostered to throw balls into a basket, to throw and receive balls in the sky above 2 meters, to exchange balls with their partner, to crashing cymbals and to walk along straight and zigzag lines. Third, the experiential music appreciation had an effect on the improvement of the physical expression ability of CDD. It fostered the expressions with body after listening sounds, which exist in the normal living fields, to imitate sounds of vehicles and animals with body, to respond appropriately as the rhythm and feeling of music, and to express it with instruments or the body. In this study, there were only three male children as participants. It is necessary to apply the program to more various subjects. There should be more following studies, which develop more various music program. The music program in this study was applied intensively in a short period. So, it is possible that there are difficulties to generalize the results and prove the significance of the results. Therefore it is necessary that the application of the music program and observation should be conducted continually.

The purpose of this study was to identify the degrees of performing self-care activities, knowledge about juvenile diabetes mellitus and symptom experience, and to investigate the performance of self-care activities by general characteristics, knowledge, symptom experience. The ultimate aim was to provide a basic data in developing nursing intervention for the children with diabetes mellitus. The subjects of this study were 42 juvenile diabetic children aged between 8 and 18 who had participated in a diabetes mellitus camp for diabetic children from July 7 to 10,1990. The subjects filled out questionnaires with knowledge about diabetes mellitus, symptom experience of diabetes mellitus, performance of self-care activities during the last 2 days of the camp. Four nursing students who had experienced with nursing care of diabetic children explained the content of the questionnaires ot the subjects. The results were as follows: 1. Mean score of performing self-care activities was 52.95, that of self-care about diet 15.68, that of self-care about blood glucose control 25.69, and that of self-care about general care 11.59. That is, 75.6% of the subjects performed self-care activities, 62.7% self-care about diet, 85.6% self-care about blood glucose control, and 77.3% self-care about general care. 2. Fifteen subjects (65.7%)scored 12 to 14, 10(23.8%) scored 10 to 11,and 7(16.7%) scored 7 to 9 in the total of 14 questions of the knowledge of diabetes mellitus. Mean score of it was 0.79 on a 0-1 point scale. 3. Of the subjects, 22 (52,4%) experienced 4 to 6 symptoms, 14 subjects 1 to 3 symptoms, and the rest 7 to 9 symptoms. Twenty-five subjects (59.5%) had no complication of diabetes mellitus, while 9(21.4%) experienced 1 complication. 4. Mean score of performing self-care about diet in diabetic children aged between 8 and 12 was significantly higher than that of those aged between 13 and 18 (P=0.0026). 5. Mean score of performing self-care about diet in primary school children was significantly greater than that of high school adolescents(P=0.003). 6. There was no significant difference in performing self-care activities, self-care activities about diet, blood glucose control, and general care by gender, religion, duration of illness, experience of hospitalization, number of participation of diabetes mellitus camp, and family history of diabetes mellitus. 7. No significant difference was observed in performing self-care activities and self-care activities about diet, blood glucose control and general care by the level of knowledge about diabetes mellitus. 8. There was no significant difference in performing self-care activities, self-care activities about diet, blood glucose control, and general care by the degree of symptom experience. These results suggest that the age is an important variable in self-care activities of diabetic children. Nursing intervention might be essential to reinforce the self-care activities for high school adolescents and to maintain the self-care activities for primary school children. And the content of existing diabetes mellitus camp program may be revised or added by the age in order to promote the practice of self-care activities of diabetic children.
