태안 반도의 학암포와 연포 해빈 천해 역에서 2007년 1월부터 12월까지 월별로 지인망으로 어류를 채집하여 계절에 따른 종조성 변화를 분석하였다. 조사 기간 동안 학암포에서는 총 30종, 964마리, 10,564.1 g의 어류가 채집되었으며, 연포에서는 총 46종, 4,447 마리, 28,622.4 g의 어류가 채집되었다. 가숭어(Chelon haematochelius)를 비롯하여 연안종인 넙치(Paralichthys olivaceus), 돛양태(Repomucenus lunatus), 조피볼락(Sebastes schlegelii), 복섬(Takifugu niphobles) 등이 우점하였고, 여름과 가을에는 전어(Konosirus punctatus), 밴댕이(Sardinella zunasi), 멸치(Engraulis japonicus)와 같은 회유성 부어류의 유어들이 대량 출현하였다. 출현한 어류는 소형어류이거나 유어들이었으며, 가숭어와 회유성 어류는 당년생 유어들이었고, 조피볼락, 넙치, 문치가자미(Pleuronects yokohamae), 쥐노래미(Hexagrammos otakii) 등과 같은 유용성 어류는 1-2년생 미성어들로, 이들은 조간대 천해역을 성육장으로 이용하며 자라면서 깊은 곳으로 이동하는 것으로 보인다. 저질이 단순한 세립 모래질 학암포 해빈에 비하여 펄이 섞인 세립 모래질이고 곳에 따라 잘피가 자라는 연포 해빈에서 출현종수와 채집 개체수가 학암포 해빈에 비하여 많았다. 두 해역에서 주거종과 여름 가을 사이 회유어종의 유어들이 출현하는 양상을 비슷하였으나, 연포에서는 봄에 펄을 선호하는 얼룩망둑(Gymnogobius mororanus), 잘피에 서식하는 실고기(Syngnathus schlegeli) 등의 성어들이 출현하였고 주거종의 미성어들의 생물량도 높았다. 황해 남쪽의 천해 역에는 외해에서 월동하고 수온이 높아지며 북쪽으로 이동하는 회유성 부어류의 비중이 높았던 반면, 황해 중북부에 위치한 태안 천해역에는 회유종의 비중은 낮았고 주거종의 비중이 상대적으로 높았다. Seasonal variation in species composition and abundance of shallow water fish from the Hakampo and Yeonpo beaches in Taean in the western coast of Korea were determined by the analysis of monthly samples collected by a beach seine from January to December, 2007. A total of 30 species, 964 individuals and 10,564.1 g of fish were collected from the Hakampo beach, and a total of 46 species, 4,447 individuals and 28,622.4 g of fish from the Yeonpo beach. The juveniles of coastal fish such as Chelon haematochelius, Paralichthys olivaceus, Repomucenus lunatus, Sebastes schlegelii and Takifugu niphobles were predominated in abundance. And the juveniles of pelagic migrants such as Konosirus punctatus, Sardinella zunasi and Engraulis japonicus were abundantly collected between summer and autumn. The fish collected were mainly composed of small-sized species and juveniles. C. haematochelius and migrant fish were young of the year, and commercially important fish such as S. schlegeli, P. olivaceus, Pleuronectes yokohamae and Hexagrammos otakii were 1 to 2 years old juveniles. It is considered that they use the shallow water as a nursery ground until they move out to the deeper water. The number of species and abundance were lower in the fine sand Hakamp beach than in the muddy sand Yeonpo beach where some Zostera marina were also found. In Yeonpo beach the adult of Gymnogobius mororanus preferred to live in the muddy shallow water and Syngnathus schlegeli living in the sea grass were also abundantly collected in spring in addition to resident fish and pelagic migrants in warm months. The resident species were more abundance in the Taean beach than in the beach located in the southern part of the west coast of Korea where the juveniles of pelagic migrants were more abundant.

한려해상국립공원 상주·금산지구와 거제·해금강지구에서 2012년 5월부터 2013년 2월까지 계절별로 이각망 등으로 어류를 채집하여 계절에 따른 종조성 변화를 분석하였다. 조사 기간 동안 상주·금산지구에서 9목 35과 58종, 2,743마리, 68,531.2g의 어류가 채집되었다. 개체수에서는 전갱이가 42.1%(1,156마리)를 차지하여 가장 많았고, 생체량은 성대가 24.5%(16,823.4g)를 차지하여 가장 많았다. 거제·해금강지구에서는 10목 27과 48종, 1,779마리, 176,629.9g의 어류가 채집되었다. 개체수에서는 전갱이가 24.1%(411마리)를 차지하여 가장 많았고, 생체량은 뱅에돔이 25.4%(44,839.4g)를 차지하여 가장 많았다. 개체수와 생체량의 계절별 변화는 수온과 관련성이 있으며, 여름과 가을철이 겨울보다 개체수와 생체량이 높았다. 상주·금산지구와 거제·해금강지구에서의 어류의 종조성은 회유성 어류에 의하여 영향을 받는 것으로 보인다. Seasonal variation in species composition and abundance of fish from the Hallyeohaesang National Park Sangju · Gumsan and Geoje · Haegumkang region in the southern sea of Korea were determined by the analysis of seasonal samples collected by fyke net etc. from May, 2012 to February, 2013. In this survey 9 order, 35 families, 58 species (2,743 individuals, 68,531.2 g) were collected in Sangju · Gumsan region. Of them Trachurus japonicus occupied 43.2% of total individuals and Chelidonichthys spinosus occupied 24.5% of whole biomass. In Geoje · Haegumkang region 10 order, 27 families, 48 species (1,779 individuals, 176,629.6 g) were collected. Of them Trachurus japonicus occupied 23.1% of total individuals and girella punctata occupied 25.4% of whole biomass. The number of individuals and biomass were higher in summer and autumn than in winter, and the seasonal variation may be related to the water temperature. Species composition of fish was affected by a migratory fish in Sangju · Gumsan and Geoje · Haegeumkang region.

A new gas-phase aerosol generator with local heating area was proposed and the effects of a carrier gas flow rate on nanoparticles synthesis were evaluated. The carrier gas, flowing around the evaporated material (Ag) on the heater, was used to enhance the formation of nanoparticles, suppress agglomeration and other particle growth mechanisms. In the various flow rates of carrier gas, the size distribution of the generated particles was measured with a differential mobility analyzer and condensation particle counter. The geometric mean diameter, geometric standard deviation, and total number and mass concentration decreases with increase of carrier gas flow rate. And, the carrier gas flow rate has effect on the decrease of agglomeration rate by dilution and the evaporation rate of material.

N/A Seasonal variation in species composition of fish in the Geum River estuary was determined using monthly samples collected with a bag net from February to December 2003. Of a total of seventy-three species collected, four groups of fishes were distinguished. Estuarine fishes such as Chelon haematocheilus and Srnechogobius hasta were collected almost all the seasons and predominated in abundance during cold months. Coastal fish species such as Sardine/la z masi, Konosirus prrctatus, Engraulis japonicas, Johnius grypotus and Thrvssa kanunalensis were dominated from late spring to autumn. Their adults entered into the estuary in spring and a large number of their juveniles were collected in summer and autumn till moving out to deeper waters for over-wintering. A few freshwater fishes were collected when the freshwater was discharged during the rainy season. Anguilla japonica elvers (diadromous fish) and Coilia nasus (amphidromous fish) were collected in spring during their upstream migration. The principal component analysis revealed that the seasonal variation in species composition of fishes was principally determined by water temperature and/or water temperature related factors.

A new gas-phase aerosol generator with local heating area was proposed and the effects of a carrier gas flow rate on nanoparticles synthesis were evaluated. The carrier gas, flowing around the evaporated material (Ag) on the heater, was used to enhance the formation of nanoparticles, suppress agglomeration and other particle growth mechanisms. In the various flow rates (2-6 Lpm) of carrier gas, the size distribution of the generated particles was measured with a differential mobility analyzer and condensation particle counter. To estimate characteristics of synthesized nanoparticles, the flow and thermal field around the heater surface of system were calculated by using commercial code, CFD-ACE+ and the particle formation process (nucleation, coagulation and surface growth) was also predicted by using a nodal general differential equation solver (NGDE) code. And, the calculation results were compared with the experiment results.

무인도 방목염소 제거에 따른 생태복원 모니터링 : 전라남도 신안군 매물도를 중심으로

김하송(Ha-Song Kim),조영준(Yeong-Jun Cho),안동순(Dong-Sun Ahn),송도진(Do-Jin Song),노형수(Hyung-Soo Noh) 국립공원연구원 2021 국립공원연구지 Vol.12 No.2

전라남도 신안군 흑산면 영산리에 위치한 무인도인 매물도에서 방목염소 제거에 따른 생태복원 위하여 1차(2016년), 2차(2018년), 3차(2021년)에 걸쳐 모니터링을 실시하였다. 그 결과, 관속식물은 40과 75속 80종 1아종 11변종으로 총 92분류군이 확인되었다. 조사된 식물 중 식물구계학적 특정식물종은 Ⅴ등급 2분류군, Ⅲ등급 5분류군, Ⅰ등급 15분류군으로 총 22개 분류군이 확인되었다. 귀화식물은 11분류군이 확인되었다. 귀화율은 11.9%이었으며, 도시화지수는 3.4%로 산출되었다. 매물도의 주요 식물군락은 목본으로는 후박나무군락, 동백나무군락, 까마귀쪽나무군락, 팽나무-까마귀쪽나무군락이 자생하였고, 초본으로는 고사리군락, 억새-사철쑥군락, 강아지풀군락, 강아지풀-갯장구채군락, 사철쑥군락, 암벽식생, 망초군락, 강아지풀-사철쑥군락 등이 나타났다. 매물도의 산림식생 중 가장 넓은 면적을 차지하고 있는 식생군락은 까마귀쪽나무군락으로 총 20.51%, 27,463.79㎡를 차지하고, 암벽식생이 11.93%, 강아지풀-갯장구채군락이 10.20% 로 조사되었다. 무인도 방목염소 퇴치 후, 식물상 변화를 모니터링 한 결과 2016년 조사에서는 미국자리공군락으로 나타났지만, 미국자리공을 인위적으로 제거하면서, 주요군락이 강아지풀군락과 갯장구채군락으로 군락변화가 나타났다. 각 고정방형구별 출현종수는 2016년 13종, 2018년 19종 (6월), 21종(9월), 2021년에는 25종으로 점점 증가하였다. 이러한 식물상 변화는 방목염소 퇴치사업에 따른 훼손지 식생복원과 지속적인 복원관리가 이루어지면서 식생대 변화가 진행되고 있었다. 방목염소 퇴치 후 주요 식생변화는 첫째, 훼손지역의 후박나무군락에서 빠르게 자연식생이 회복되고 있었다. 후박나무군락의 맹아줄기 변화, 맹아줄기 성장 변화, 맹아줄기 개체수 등의 식생변화는 방목염소들의 먹이 활동으로 인한 후박나무 생육 피해가 중단되면서 정상적인 식생회복이 진행되고 있는 것으로 판단된다. 둘째, 방목염소 퇴치 전, 초본식생의 단순화가 나타나면서 생태계 교란이 나타났다. 방목염소 퇴치 후, 교란지역을 중심으로 외래식물 제거와 인위적인 자생식물 식재, 이식한 묘목 관리가 지속적으로 이루어지면서 주요 초본식생 분포비율(%)의 변화가 나타나고 있었다. 셋째, 과거 방목된 염소로 인하여 산림식생의 하층부인 관목층과 초본층에서 염소들의 휴식공간, 서식공간으로 이용되면서 많은 식생교란이 나타난 상록활엽수림의 하층에서는 후박나무, 산뽕나무, 갯기름나물, 송악, 댕댕이덩굴, 왕모시풀, 큰천남성, 닭의장풀, 노랑하늘타리, 밀사초 등이 나타나면서, 군락내에 종구성은 계속적으로 변화할 것으로 예상된다. The 1st (2016), 2nd (2018), and 3rd rounds (2021) were monitored for ecological restoration following the removal of grazing goats on Maemuldo, an uninhabited island located in Yeongsan-ri, Heuksan-myeon, Sinan-gun, Jeollanam-do. As a result, vascular plants were identified with 40 families, 75 genera, 80 species, 1 subspecies, 11 varieties, and a total of 92 taxa. Among the investigated plants, a total of 22 taxa were identified as specific plant species in the phytogenetology: Class V 2 taxa, Class III 5 taxa, and Class I 15 taxa. For naturalized plants, 11 taxa were identified. The naturalization rate was 11.9%, and the urbanization index was calculated as 3.4%. The main plant communities of Maemuldo were Machilus thunbergii community, Camellia japonica community, Litsea japonica community, and Celtis sinensis-Litsea japonica community. Pteridium aquilinum var. latiusculum community,Miscanthus sinensis - Artemisia capillaris community, Setaria viridis community, Setaria viridis-Silene aprica var. oldhamiana community, Artemisia capillaris community, rocky vegetation, Conyza canadensis community, Setaria viridis -Artemisia capillaris community appeared. Among the forest vegetation of Maemuldo, the vegetation community that occupies the widest area is the Litsea japonica community, which occupies a total of 20.51%, 27,463.79㎡, 11.93% of the rocky vegetation, and 10.20% of the Setaria viridis-Silene aprica var. oldhamiana community. As a result of monitoring the change of flora after extermination of goats grazing on uninhabited islands, in the 2016 survey, it was found to be an Phytolacca americana community, but as the Phytolacca americana community was artificially removed, the major colonies were changed to Setaria viridis community and Silene aprica var. oldhamiana community. The number of species that appeared in each fixed rectangle gradually increased to 13 species in 2016, 19 species (June), 21 species (September) in 2018, and 25 species in 2021. The change of vegetation was progressing as the vegetation restoration of damaged areas and continuous restoration management were carried out according to the grazing goat extermination project. The major vegetation change after the extermination of grazing goats was first, that the natural vegetation was rapidly recovering in the locust community in the damaged area. Vegetation changes such as sprouting stem changes, sprouting stem growth changes, and sprouting stem populations of Machilus thunbergii community. goat colony are considered to be in progress as normal vegetation recovery is in progress as damage to the growth of Machilus thunbergii community. Second, before the extermination of grazing goats, the simplification of herbaceous vegetation appeared, causing ecosystem disturbance. After extermination of grazing goats, as the removal of alien plants, artificial planting of native plants, and management of transplanted seedlings were continuously carried out centered on disturbed areas, changes in the distribution ratio (%) of major herbaceous vegetation were observed. Third, in the lower layer of the evergreen broad-leaved forest where many vegetation disturbances occurred as it was used as a resting space and habitat for goats in the shrub layer and herbaceous layer, which are the lower layers of forest vegetation due to past-grazing goats, As Machilus thunbergii, Morus bombycis, Peucedanum japonicum, Hedera rhombea, Cocculus trilobus, Boehmeria pannosa, Arisaema ringens, Commelina communis, Trichosanthes kirilowii var. japonica, Carex wahuensis var. robusta, etc. appeared, the species composition within the community is expected to change continuously.
