갯쥐꼬리풀(Spartina alterniflora)은 북미 대서양 연안 뉴펀들랜드, 캐나다 남쪽에서 아르헨티나 북부의 갯벌이 원산이며, 생장이 강한 특성으로 세계의 기수지역과 해안에서 생태공학적 용도로 도입된 바 있다. 그러나 매우 빠르게 갯벌을 피복하여 자생종의 생장을 방해하고, 염습지 종다양성을 감소 시켰고, 결과적으로 과다생육으로 갯벌 무척추동물의 서식지를 잠식해 사라지게 하여 무척추동물을 먹이로 하는 조류 또한 생태계 내에서 감소키는 등 많은 환경문제를 야기 시켰다. 우리나라에서는 2008년 전후에 다도해해상국립공원에 유입된 것으로 판단된다. 현재 다도해해상국립공원 남동리 해안에서 분포하고 있는 갯쥐꼬리풀(Spartina alterniflora)군락은 습지내 총 6개의 염생식물 군락면적(8,487.7㎡) 중 75.34%의 비율(6,394.86㎡)로 분포하고 있다. 또한 2008년에 11.54㎡ 이던 분포 면적이 2015년 현재 약 550배가 늘어난 6,394.22㎡로 조사되었고 생육지 고도 범위인 0.69m~1.1m를 요인 값으로 두고 GIS 분석한 하였다. 그 결과 앞으로 확산 될 예상 면적은 12,584㎡이며 현재보다 약 6,189.14㎡가 늘어날 것으로 예측되며 우리나라에서도 역시 확산이 빠르고 넓게 늘어날 것으로 판단된다. 향후 계속 분포역이 확대 될 것으로 예상하고 관리방안을 위하여 시범 연구를 실시하였다. 갯쥐꼬리풀군락 중 일부를 첫 번째는 뿌리째 뽑아내기와 두 번째 지상부 제거 후 포장덮기 방법 등 국외사례의 문헌을 바탕으로 방재를 실시하였으나 전체 면적을 방재하기에는 많은 인력과 시간 그리고 예산이 소요되므로 다각적인 방안을 강구하여야 한다. Spartina alterniflora is native to the Atlantic coast from Newfoundland, the south of Canada and northern Argentina. There it forms a dominant part of brackish coastal saltmarshes. Due to its strong growth, the Spartina alternifolra was introduced to the rider area and coast as a use for ecological engineering. The Spartina alterniflora community can crowd out native species, reduce the biodiversity of saltmarsh and alter the environment. As a result, the invertebrates living in mud flats disappeared due to the encroaching of Spartina alterniflora, and the birds which eat off invertebrates went along as well. The Spartina alterniflora was first introduced in South Korea in 2008 and is known to have flowed in the Dadohaehaesang National Park. Compared to 2008, in 2015 the distribution area of the Spartina alterniflora has increased 550 times. (11.54㎡ in 2008 to 6,394.22㎡ in 2015). The large increase of Spartina alterniflora calls for urgent management and additionary study on the subject. Thus, this study analyzed the geo-spatial information on the Spartina alterniflora such as its distribution area, the height of habitats and expected expansion area, and can act as the preliminary data for management.
월악산국립공원의 부착규조 분포와 유기오탁지수 (DAIpo)에 의한 수질평가
박정원(Jung-Won Park) 국립공원연구원 2010 국립공원연구지 Vol.1 No.2
본 연구는 2006년에 월악산국립공원 내에 부착규조류 분포와 유기오탁지수에 의한 수질 평가이다. 동정된 부착규조류는 138종류였고, 우점종은 Achnanthes sp. Achnanthes alteragracillima, Achnanthes convergens, Achnanthes minutissima, Cocconeis placentula var. lineata, Cymbella affinis, Cymbella silesiaca, Gomphonema minutum, Reimeria sinuata 등이었다. DAIpo 값은 62.3에서 99.9의 범위로, 매우 좋음에서 좋음으로 평가되었다. To investigated the epilithic diatoms community and an assesment of water quality by DAIpo(diatom assemblage index of organic water pollution), the samplings were collected from fourteen sampling stations on April, May, August, September and October 2006 in Woraksan National Park. The total 138 taxa were identified from this study and dominant species were Achnanthes sp. Achnanthes alteragracillima, Achnanthes convergens, Achnanthes minutissima, Cocconeis placentula var. lineata, Cymbella affinis, Cymbella silesiaca, Gomphonema minutum, Reimeria sinuata. The variations of DAIpo values was ranged from 62.3 to 99.9 and the water quality was estimated between very good and good.

Purpose: To evaluate the effects of a mixed solution of sodium hyaluronate and sodium carboxymethylcellulose (HACMC, Guardix-sol®) for reducing postoperative adhesion after endonasal dacryocystorhinostomy. Methods: Endonasal dacryocystorhinostomy was performed on 58 patients with obstructions of the nasolacrimal system. We divided the 58 patients into two groups. At the completion of endonasal dacryocystorhinostomy, HACMC was applied to the operative site in the experimental group (n=26) and normal saline was applied in the control group (n=32). For the evaluation of clinical effectsand postoperative adhesion, subjective symptom score evaluations, lacrimal irrigation tests, fluorescein disappearance tests, and endoscopic examinations were performed at 1 week, 1 month, 3 months, and 6 months postoperatively. Results: The HACMC-treated patients showed better results than the control patients for subjective symptom scores, lacrimal irrigation tests, and fluorescein disappearance tests, but these differences were not statistically significant. Upon endoscopic examination, the HACMC group revealed lower incidence of adhesion at 1 week after surgery and lower severity of adhesion throughout the period of observation (p<0.05). Conclusions: The application of a mixed solution of HACMC may effectively reduce postoperative adhesion after endonasal dacryocystorhinostomy. J Korean Ophthalmol Soc 2010;51(6):795-801

박정원,정준 ( Chung Won Park,Jun Chung ) 한국하천호수학회 1996 생태와 환경 Vol.29 No.1
To investigate the ecological variation of the genus Scenedesmus populations, the survey had been carried out at nine sampling stations in the Kumho river in every two month interval from October, 1990 to August, 1993. The total number of taxa collected from this area were classified into 38 species, 6 varities, 2 formae, and also they appeared 21∼39 taxa at each station. Relationship between environmental factors and standing crops, population density of the Scenedesmus was high at water temperature 9.7∼27℃, EC average 311∼614 S/cm, BOD average 2.47∼12.72 ppm. The important species investigated as followes: S. acutus, S. communis, S. opoliensis, S. serratus, S. spinosus. The subgenus Acutodesmus and Scenedesmus were high occupancy percentage of standing crops between α-oligosaprobic and α-mesosaprobic. But the subgenus Desmodesmus was high between β-mesosaprobic and polysaprobic. By the results obtained this study, the genus Scenedesmus populations distributed in the different environment. And also the subgenus Acutodemsus(including the subgenus Scenedesmus) and the subgenus Desmodesmus showed to be the ecological diversity each other.
