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.

한경임,공유미 한국특수교육문제연구소 2004 특수교육저널 : 이론과 실천 Vol.5 No.1

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.

韓鏡秀,張權烈,高美錫 진주농과대학 1970 진주농과대학 연구논문집 Vol.- No.9

小豆의 收量에 影響하는 形質을 正確히 알기 爲하여 形質相互間의 相關關係 그리고 經路係數分析과 各形質相互間의 表現型共分散, 遺傳共分散, 環境共分散 등을 計算하고 여러가지 選拔指數를 作成하여 選拔實驗을 한바 그 結果를 要約하면 다음과 같다. (1) 各形質相互間의 表現型共分散의 값보다 遺傳共分散의 값이 大體로 크고 環境共分散은 그 값의 變動이 甚하다. (2) 遺傳相關의 값이 表現型相關보다 높으며 開花日數와 1株重量, 莖長과 1株重量, 莖直徑과 分枝數, 莖直徑과 1株重量, 莖直徑과 100粒重, 分枝數와 1株重量, 1株重量과 100粒重間에는 높은 正의 相關을 보였고 收量과는 莢數만이 높은 正의 相關을 보였다. (3) 收量에 미치는 諸形質의 直接的 影響을 보면 莢數, 莖直徑, 100粒重, 莖長, 開花日數의 順으로 收量에 正으로 影響하며, 間接的 影響을 보이는 形質은 主로 莢數는 分枝數의 增加로 收量에 間接的으로도 影響하는 것을 알수 있다. 그리고 莖直徑은 開花日數, 莢長, 分枝數, 1株重量, 100粒重과 間接的으로 作用하여 收量에 影響하고 1株重量은 莖直徑, 莢數, 100粒重의 3形質과 100粒重은 開花日數, 莖直徑, 分枝數, 1株重量, 100粒重과도 間接的으로 影響을 미치는 것을 알수 있다. (4) 各形質을 選拔對象 形質로 하여 選拔指數를 作成한바 第3表 및 第4表와 같이 形質의 組合에 따라서 選拔에 관여하는 各形質의 加重値(weight)는 다르나 부호는 大體로 同一하다. (5) 選拔指數에 依한 遺傳的 進展과 그의 關係效率을 본바 單一形質에 있어서는 莢數, 1株重量, 100粒重의 效率이 높고 單一形質보다 2個形質을 2個形質보다 3個形質을 選拔對象形質로 하여 選拔하는 것이 效果的이라는 것을 알수 있다. 以上의 結果를 미루어 보아 小豆의 形質中 莖長, 莖直徑, 莢數, 100粒重의 4個形質이 收量에 直接 또는 間接으로 影響하는 重要形質이 될 수 있을 것으로 믿는다. 그리고 小豆에 있어서는 莖長(X₂), 莖直徑(X₃), 莢數(?), 100粒重(??)의 4個形質中에서 2-3形質을 選拔對象形質로 하여 選拔指數를 作成하여 選拔에 應用하는 것이 時間과 勞力 그리고 選拔效果面에 있어서 效果的일 것으로 믿는다. The studies were intended to clarify the correlations between the characters and the influences of each character upon yield of Adzuki beans. The analysis of covariance was conducted to obtain the genotypic correlations among eight characters-days to flowering, stem length, stem diameter, number of branches per plant, number of pods per plant, plant weight, 100 grain weight and grain weight(yield), etc., and the path-coefficients were calculated by Dewey's method. Selection indexes were calculated by phenotypic and genotypic covariances between the characters, and genetic advances and relative efficiency were also calculated for these characters. The results obtained are summarized as follows: (1) The yield of Adzuki bean was mainly associated with the character, number of pods per plant. (2) The values of genotypic covariances were slightly higher than those of phenotypic covariances between the characters. (3) Stem length, stem diameter, number of pods per plant, and 100 grain weight had a direct positive influence upon the yield of Adzuki beans. (4) Number of branches per plant and total plant weight had little or negative influences upon yield but it had rather considerable indirect influence upon yield by increasing the other characters. As a result, it can be concluded that Adzuki bean yield is primarily determined by increasing number of pods per plant, in turn the yield of Adzuki bean is secondarily determined by the number of pods per plant. (5) Many selection indexes which contain 1-7 characters in calculation were obtained as shown in Tables 2 and 3, and they show the genetic advances and relative efficiency which were calculated with various selection indexes. These results suggest that selection index technique is useful in Adzuki bean breeding. In reality, however, as the selection index varies with population and environment in which the population is located. Inspite of the expected usefulness of selection index technique in Adzuki bean breeding, unsolved problems such as the expense, time and labor involved in calculating the selection index remain. For these reasons and from these studies, it was realized that the selection index for the selection should be calculated on the basis of the data of some 3-4 characters, stem length, stem diameter, number of pods per plant, and 100 grain weight, etc. These characters should be very useful agronomic characters in the selection of Korean Adzuki beans, as they could be measured or counted easily thus saving time and expense, and have a greater effect on more Adzuki bean yield than the other agronomic characters.

뇌성마비 아동의 통합치료교육 사례 연구

한경임,송미승,박철수 한국특수아동학회 2003 특수아동교육연구 Vol.5 No.1

본 연구는 한 뇌성마비 아동의 언어치료와 물리치료의 통합치료교육에 대한 사례 연구이다. 연구대상은 전남 D대학교 언어ㆍ청각임상 센터에서 치료를 받고 있는 아동으로 치료를 시작하기 전 언어장애 진단과 발달 영역별 진단 결과 스스로 신변자립이 불가능하고, 호흡도 스스로 조절하기가 어려운 상태였다. 또한 머리 조절이 불가능하여 사물을 주시하거나 손을 움직여 지적하기도 어려운 상태였다. 치료 초기에는 호흡과 인지 능력의 개선을 위한 지도에 중점을 두었다. 그러나 머리 조절이 어려운 관계로 호흡 훈련에 큰 진전이 없어 물리치료적인 측면에서의 진단을 통해 언어치료와 물리치료에서 통합적인 치료가 이루어지도록 수행하였다. 그러한 통합치료적인 접근을 수행하여 현재 치료가 이루어지고 있으며, 머리조절 개선과 함께 호흡조절과 발성 시간의 증가가 향상되고 있음을 알 수 있었다. 향후 치료에서도 통합적인 관점에서 치료교육이 수행될 수 있도록 계획하고 지속적으로 학생의 발달 진전 사항을 관찰할 예정이다. This study is a case study on the interdisciplinary team approach for therapeutic education of a child with severe cerebral palsy. The subject is a female elementary school student being registered in a Language & Audilogy Center, Chonnam province. She is a non-ambulatory and nonverbal student. Before starting therapeutic education it was impossible for her to control of her head, respiratory and had movement. Because of non-control of her head she can not move her arm and hand freely and control the visual-movement coordination. In the beginning of therapeutic education, it was focused to the speech therapy composed to respiratory and voice production. But it was not effective. After interdisciplinary team approach including speech therapy as well as physical therapy, she was able to control her head movement, respiratory and voice production a little. According to control her head movement she can control her hand movement a little and accept the possibility of Augmentative and Alternative Communication intervention. In Conclusion, this results represent the importance of interdisciplinary team approach in the therapeutic education for children with cerebral palsy. Based on the above conclusion, it is need for following studies to develop transdisciplinary team approach program for therapeutic education and adapt it to the field of special education. And following studies need to include more various therapeutic education area and include more subjects.

한경자,최명애,강창희,구미옥 서울대학교 간호대학 간호과학연구소 1995 간호학 논문집 Vol.9 No.1

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.

The purpose of the study was to investigate the lifestyle and individualism/collectivism of adolescents nowadays and the relationship to preferred sensation. We collected 1386 middle and high school students' data which have the answers about lifestyle, individualism/collectivism, self-esteem, school location, family members and other socio-statistical variables. The results are followings; The types of adolescents' lifestyle composed of 5 clusters, which are Pursuit of hedonic (18.9%), Adventure materialism (19.9%), Depending and pursuit of entertainment (21.4%), Internet & study (22.5%), and Strong will - economic (17.3%). Distribution of individualism/collectivism is even, and Egoist (29.8%) which belong to vertical individualism is the biggest portion. Adolescent's lifestyle has relationship to the external factors, such as school location and family income, while individualism/collectivism does rather to adolescent's own nature, such as gender and grade. Their lifestyle than their individualism/ collectivism is connected with their preferred sensation more.
