洛東江 河口의 植生에 관한 硏究 : The Biomass of Foodplants for the Migration Birds 철새의 먹이植物을 中心으로

尹解順 東亞大學校 大學院 1984 大學院論文集 Vol.9 No.-

The estimation of biomasses of such foodplants as Scirpus tirqueter, Zostera noltii, Potamogeton crispus and vallisneria asiatica was carried out at the estuary and related area of Nakdong River, since these plants have been known as foodplants for the birds. Among these plants, especially, the total biomass of Scirpus and Zostera were remarkably reduced from Oct. to Jan., and then the rate of the reduction decreased moderately from Jan. to Apr. The underground parts of Scirpus decrease to 7.6% during the winter in the muddy area. And the biomass reduction of Zostera was similar to that of Scirpus. These results suggest that such plants are important as feeding materials for the herbivorous and omnivorous birds and these plants are under the relatively heavy feeding pressure.

洛東江 河口堰 축조 후의 水生管束植物의 現存量 변화에 관한 硏究

윤해순 東亞大學校附設基礎科學硏究所 1993 基礎科學硏究論文集 Vol.10 No.1

Seasonal changes in biomass of vascular hydrophytes in Jukrim branch, the dead west branch of Nakdong river, was estimated from July 1991 to May 1992, and was compared to that before the construction (1984-1986) of Nakdong barrage. 1. The area of vascular hydrophytes distribution, and their biomass, decreased in summer months, compared to those before construction of the barrage. 2. Percent composition of floating plants(Trapa spp.) and semifloating plants(Patamogetom spp.) increased significantly. while that of submerged plants (V. asiatica and Najas spp.) decreased. These results suggest that the water body of Jukrim branch in the process of eutrification, and indicates the need for proper treatment of industrial and farmaland wastewater before discharge into Jukrim branch.

光合成 活性에 대한 EDTA의 效果 : 大麥 葉組織의 老化過程中의 活性을 中心으로

尹解順 東亞大學校 敎育大學院 1984 敎育大學院 論文集 Vol.10 No.-

The effect of EDTA on the photosyntheic activity during the ageing in Barley (Hordeum vulgare L.cv. Baecdong) leaves was investigated by the changes of chlorophyll, protein and electron transport activity. The changes of chlorophyll, carotenoid and protein were remarkably decreased in dark conditon. But in light condition, the amount of them was moderately decreased. Addition of EDTA at concentration 3mM in light condition has bring about the reduction in total chlorophyll and carotenoid. But in dark condition with EDTA, the changes of them were moderatly decreased than the control(without EDTA). The contents of protein was not influenced by EDTA in the dark and light. Effect of EDTA in photosynthetic electron transprt activity was different in light and darkness. Especially PS Ⅱ of the photosynthetic electron transport activity was remarkably reduced in light with EDTA. In these results means that light was important for the production of chlorophyll, carotenoid and protein. EDTA treatment retarded the degradation of chlorophll in the dark but depressed the activity of PS Ⅱ and the total photosynthetic electron transport activity in light.

서낙동강 수질의 이화학적 특성과 수생관속식물의 분포

윤해순,김구연,김승환,이원화,이기철 한국생태학회 2002 Journal of Ecology and Environment Vol.25 No.5

서낙동강의 물과 저토의 이화학적인 환경을 측정하고, 수생관속식물의 식생을 조사하였다. 수질은 수소이온농도, 용존산소, 엽록소a, 총질소 그리고 총인에 의하면 부영양화 상태이었으나 여름에는 지소에 따라 과영양 상태이었다. 수중 저토는 약산성 이었으며, 모래의 함량이 높았으나 SI는 점토, SU는 미사의 비율이 컸다. 수생식물 분포는 총 16과 26종 1변종으로 총 27분류군이었다. 지소별 우점종은 DU, GA 그리고 SU에서는 마름(Trapa japonica)이 우점하였고, DA에서는 노랑어리연꽃(Nymphoides peltata), SI는 자라풀(Hydrocharis dubia)이 우점하였다. SI와 SU에서 종다양도, 균등성이 높았으며, 우점도는 DA에서 높았다. 6월에 유입된 외래종 물상추(Pistia stratiotes)와 부레옥잠(Eichhornia crassipes)이 수역 전체에 확산되어 서낙동강 전체의 우점종이 되었다. 낙동강 하구둑 축조 당시와 비교하여 서낙동강에서 소멸된 종은 민나자스말(Najas marina), 톱니나자스말(Najas minor), 이삭물수세미(Myriophyllum spicatum), 어리연꽃(Nymphoides indica)이었다. 수생식물의 최대 현존량은 10월에 DU에서 가장 높았다(445g·Dw/㎡). 하구둑 축조당시인 1985년에 비하여 DU와 CA지소의 총현존량은 33.5%로 감소하였으며, 우점종 마름의 감소율이 56.7% 이었다. 종 수와 유사도 지수를 근거로 집괴분석한 결과에 따르면 GA-SU-DU, DA와 SI의 3집단으로 구분되어졌다. 외래종의 유입으로 인한 수생식물군락의 교란은 SI와 SU에 분포하는 가시연꽃(Euryale ferox)과 감소추세 종 자라풀을 포함하여 수역전체의 자생종들 특히 수금류의 먹이식물로 이용되는 마름, 나사말, 말즘 등의 감소를 초래하였다. The physico-chemical characteristics of water and sediment, and structures of vegetation of the vascular hydrophytes were investigated in the West Nakdong River. Water quality was eutrophic according to the mean values and the ranges of water properties such as pH, DO, BOD, chlorophyll a, total nitrogen and phosphate, and other nutrients. A few cases were hypereutrophic for chlorophyll a level in summer. Soil reaction was weak acid. Composition of sediment was mainly sand except in SI(Sinan chideung) of which was mainly clay, and SU(Suan chideung) of which was mainly silt. Flora of vascular hydrophyte had 26 species and 1 variety comprising 16 families. Trapa japonica was dominant species in the sites of DU(Dunchido), GA(Garak chideung) and SU. Nymphoides peltata and Hydrocharis dubia dominated in DA and SI, respectively. Species diversity and evenness were relatively high in SI and SU but dominance was high in DA. After June, water lettuce(Pistia stratiotes) and water hyacinth(Eichhornia crassipes) were flowed from tributary to the river. Standing crop of macrohydrophytes was high in DA from April to August, but it showed maximum standing crop (445g·dw/㎡) in DU after disturbance by explosive growth of exotic plants in October. In comparison with those in 1985, total productivities in DU and GA decreased to 33.5%, and the reduction ratio of dominant species, Trapa japonica was 56.7%. Najas marina, N. minor, Myriophyllum spicatum and Nymphoides indica have disappeared ever since the Nakdong barrage was constructed in the Nakdong river. They were divided into three groups (GA-SU-DU, DA, SI) by cluster analysis. Introduction of the exotic species in this river caused decreasing of endemic plants including endangered species Euryale ferox and rare species Hydocharis dubia, and food plants for waterfowl such as Trapa japonica, Vallisneria asiatica and Potamogeton crispus.

윤해순,윤숙영,최병진 인간식물환경학회 2018 인간식물환경학회지 Vol.21 No.5

The purpose of this study was to look into the effect of horticultural activities designed to stimulate five senses on a child’s sensory development. This study selected 22 children at ‘H’ child community center located in D city as research subjects, and conducted a program consisting of 12 sessions (once a week) from January 4 to March 29, 2017. Each session’s horticultural activities were designed to stimulate all five senses in children. The research results are as follows: first, the control group didn’t show any significance in changes of attention concentration by sense before/after implementing the program, but in case of the experimental group, all senses but a major hand tactile sense were found significantly improved. For visual sense assessments, selective attention was improved from 4.5 scale before implementing the horticultural activity to 7.6 scale(p=.000); sustained attention was improved from 4.3 scale before implementing the activity to 7.8 scale after implementing the activity(p=.000); self-control was improved from 4.3 scale before implementing the activity to 7.3 scale (p=.000), and in case of tactile concentration, a non-major hand dexterity was enhanced from 29.6 seconds before implementing the activity to 23.2 seconds(p=.000) after implementing the activity, but a major hand didn’t show any significant change. In the measurement of auditory concentration, it was significantly improved from 9.4 score before implementing the activity to 12.2 score (p=.001) after implementing the activity. Olfactory concentration was also significantly improved from 1.2 score before implementing the activity to 2.2 score(p=.002) after implementing it. Taste concentration was also found improved significantly from 4.3 score before implementing the activity to 5.6 score(p=.001) after implementing it. The results suggest that applying horticultural activities that can stimulate all five senses using natural objects familiar and interesting to children will be effective for sensory development of children.

조규갑,윤해순 東亞大學校附設基礎科學硏究所 1996 基礎科學硏究論文集 Vol.13 No.2

경남 양산군에 위치한 천성산을 1995년 8월부터 1995년 12월까지 모두 4차례에 걸쳐 토양과 임상을 조사하였다. 이를 토대로 식생 및 종조성을 생태학적인 측면에서 분석하였으며 그 결과는 다음과 같다. 1. 천성산에 분포하는 관속식물은 38목 73과 235종 1아종 38변종 5품종으로 총 275종류이다. 본 조사구에 출현한 목본식물은 23목 37과 91종 9변종 4품종으로 총 104종류이다. 2. 본 조사지의 전체적인 우점종은 소나무이고 고도에 따른 우점종 및 준 우점종을 보면 200m지역에는 졸참나무, 때죽나무, 400m지역에는 개서어나무, 털진달래, 600m지역에는 떡갈나무, 털진달래가 각각 우점종 및 준우점종을 이루고 있다. 3. 종 다양도는 토양 비옥도가 높은 N-I, E-Ⅲ지역이 높았고 토양 비옥도가 낮은 W-III, S-Ii에서는 낮게 나타났다. 4. 조사구간의 유사도 지수는 S-I과 S-Ⅱ에서 57.2%로 가장 유사하였고 E-I과 N-Ⅲ에서는 80.2%로 상이도 지수가 높았다. 5. Bray방식에 의한 각 조사구간의 극서열방법에 따른 2차원 그림에서 S-Ⅱ와 S-Ⅲ간에, E-I, E-Ⅱ 그리고 S-I간에, WⅡ, W-Ⅲ, NI과 N-Ⅱ지역에서 각각 유사성을 나타내었다. The vegetation of Mt. Chonsong, Yangsan-Kun, Kyungsang-Nam Province, was investigated by phytosociological method. Vascular plants consisted of 38 orders, 73 families, 235 species, 1 subspecies 34 varieties, and 5 formae or 275 taxa. Woody plants were composed of 23 orders, 37 families, 91 species, 9 varieties, and 4 formae or 104 taxa. Dominant species was Pinus densiflora in Mt. Chonsong. Quercus serrata and Styrax japonica were codominated as an important species at the 200m sea level. Carpinus tschonoskii and Rhododendron mucronulatum var. ciliatum(400m), Q.dentata and Rhododendron mucronulatum var. ciliatum were important species at the 600m. The species diversity indices were relatively high in the fetile sites at N-I and E-Ⅲ. From the similarity index, vegetation pattern were very close similarity between S-I, and S-Ⅱ sites as 57.2%, but E-I and N-Ⅲ sites as 19.8% were different.
