        습지 유형별 담수 무척추동물의 다양성 비교 (=김천시를 중심으로)

        김형곤 ( Hyoung-gon Kim ),이영식 ( Young-sik Lee ),정선우 ( Seon-woo Cheong ) 한국환경기술학회 2018 한국환경기술학회지 Vol.19 No.5

        본 연구에서는 김천시의 습지 유형별 담수 무척추동물의 다양성 비교를 하였다. 채집된 담수 무척추 동물의 평균 종수는 광기습지28.50(±0.71)<sup>a</sup>, 도곡리보습지28.00(±2.83)<sup>a</sup>, 길지습지15.00(±4.24)<sup>b</sup>, 동부습지4.50(±0.71)<sup>c</sup> 순이었고 Duncan의 다중범위 검정 결과, 하천형, 호수형, 소택형 등 습지의 유형별로 차이가 있었다. 하천형 습지인 광기습지와 도곡리보습지의 종구성은 하루살이목, 날도래목등 전형적인 유수생태계의 특성을 나타내었으며 호수형 습지인 길지습지와 소택형 습지인 동부습지의 종 구성은 노린재목, 딱정벌레목 등이 우세하게 분포하는 전형적인 정수생태계의 특성을 보였다. 집괴분석 결과, 정수성 습지와 유수성 습지가 다른 두 그룹으로 묶이는 것을 확인 할 수 있었는데 이는 정수생태계에 적응하여 서식하는 분류군(노린재목, 딱정벌레목 등)과 유수생태계에 적응하여 서식하는 분류군(하루살이목, 날도래목 등)이 서로 상이하기 때문에 나타난 결과라고 판단된다. In the present study, we compared the biodiversity of freshwater invertebrates by wetland types in Gimcheon city. The average number of species of the collected freshwater invertebrates are Gwanggi wetland 28.50(±0.71)<sup>a</sup>, Dogokri wetland 28.00(±2.83)<sup>a</sup>, Gilji wetland 15.00(±4.24)<sup>b</sup>, Dongbu wetland 4.50(±0.71)<sup>c</sup>. As a result of Duncan’s multiple range test, we reached the conclusion that the results depend on wetland types such as Riverine, Lacustrine and Palustrine. Gwanggi and Dogokri wetlands, which are Riverine, show typical attributes of Lotic ecosystem that we could find Ephemeroptera, Trichoptera. Meanwhile, Gilji and Dongbu wetlands, which are Lacustrine and Palustrine respectively, have characteristics of Lentic ecosystem that Hemiptera and Coleoptera inhabit dominantly. As a result of Cluster analysis, we could classify Lentic and Lotic wetlands into two different groups because the species which adjusted to Lentic ecosystem(Hemiptera, Coleoptera) and the ones that adjusted Lotic ecosystem(Ephemeroptera, Trichoptera) are different.

        섬진강 하구역 습지에서 쇄방사늑조개 대량발생 원인파악을 위한 수질환경 연구

        김형곤 ( Hyoung-gon Kim ),정정조 ( Cheong-jo Cheong ),정선우 ( Seon-woo Cheong ),김형수 ( Hyeong-su Kim ),이영식 ( Young-sik Lee ) 한국환경기술학회 2018 한국환경기술학회지 Vol.19 No.4

        본 연구에서는 최근 섬진강 하구역 습지에서 쇄방사늑조개의 대량발생 원인 파악을 위하여 개체의 특성 및 수질환경을 알아보았다. 채집된 개체의 각장은 11.82 ~ 20.93 mm, 각고는 7.75 ~ 13.15 mm, 각폭은 4.60 ~ 8.70 mm의 범위였다. 수질환경요인 중 수온, pH, DO는 2016년과 2017년의 월별 패턴의 변화양상이 유사하나 쇄방사늑조개가 대량 발생한 2017년에는 염분농도가 높았다. 염분농도의 변화는 강수량과 서로 유의한 상관성을 보였는데 이는 강수량이 염분농도의 변화에 영향을 주기 때문이다. 이를 통해 염분농도의 변화가 쇄방사늑조개의 대량발생에 있어서 주요 요인으로 작용했을 것으로 판단된다. In this study, water environment and individuals characteristics of Seomjin river estuary wetland were examined to find out the cause of bloom of Potamocorbula amurensis in the area. Collected individuals show 11.82 ~ 20.93 mm shell length, 7.75 ~ 13.15 mm shell height, and 4.60 ~ 8.70 mm shell width. Among the water environmental factors, water temperature, pH, and DO have similar change aspects in 2016 to 2017. However, salinity of Seomjin river estuary was higher in 2017 than it was in 2016. This phenomenon could be explained by the fact that precipitation affects on salinity of water. Therefore, it is determined that the changes of salinity is the main factor of bloom of Potamocorbula amurensis,

        지리산 주요 수계의 저서성 대형무척추동물 군집분포의 특성

        김형곤 ( Hyoung Gon Kim ),윤춘식 ( Chun Sik Yoon ),황종우 ( Jong Woo Hwang ),박은희 ( Eun Hee Park ),정선우 ( Seon Woo Cheong ) 한국환경과학회 2014 한국환경과학회지 Vol.23 No.2

        We have studied characteristics of community structure on the benthic macro-invertebrates at twelve selected sites in upstream, midstream and downstream of Paemsagol, Piagol, Chilseongol and Daeseonggol, major streams of Jirisan Mountain, for three years from April 2008 to September 2010. As a result, 2 phyla, 3 classes, 11 orders, 41 families, 119 species and 4,449 individuals of benthic macro-invertebrates have been collected and classified in this study. Among them EPT group (Ephemeroptera, Plecoptera, Trichoptera), commonly appearing taxa in clean stream ecosystem, was found most frequently. The highest species number of benthic macro-invertebrates were collected in 2008, the year with lower climatic influence including heavy rain. In almost all of survey sites 80% or over of EPT group were counted, and St. 1 scored highest rate of EPT group at 92.59%. Most dominant species was Ecdyonurus kibumensis at 12.83% of dominance index, and subdominant species was Goerodes KUb at 6.81% of dominance index. The investigation of the feeding function group indicated that gathering-collectors were dominant with 26 species and 1,334 individuals, while the number of filtering-collectors was lowest with 11 species and 230 individuals. This result represents that the feeding function group of Jirisan Mountain is mountainous stream-specific one. Both diversity index and richness index were lowest at the midstream of Chilseongol (St. 5), while the midstreams of Daeseonggol (St. 11) and Piagol (St. 8) were highest in diversity and richness indices respectively. The analyses of linear regression and correlation were performed in order to investigate and to predict the appearance aspect of EPT group by altitude. The results showed that the ratio of Plecopteran species number has increased by the elevation of the altitude at 0.05 significance level. Cluster analysis was also carried out for evaluating environmental similarities among survey sites. As a result, upper regions of Paemsagol (St. 1) and Piagol have clustered as most similar sites each other, while the midstream of Piagol (St. 8) has separated with lower similarity value than other sites in species composition.

        집중호우에 의한 서식지변동이 저서성 대형무척추동물의 분포에 미치는 영향

        김형곤 ( Hyoung-gon Kim ),윤춘식 ( Chun-sik Yoon ),정선우 ( Seon-woo Cheong ) 한국환경과학회 2018 한국환경과학회지 Vol.27 No.8

        The changes on community structures of benthic macroinvertebrates, relevance to the environment and interrelationship between benthos were studied over two years in stream with large environmental disturbance, which caused by localized heavy rain during Typhoon Chaba in October 2016. As a result, the number of species and individuals were increased after localized heavy rain, especially numbers of individuals of Ephemeroptera and Plecoptera were greatly increased. On the contrary, those of Semisulcospira libertina and Semisulcospira forticosta of Mesogastropoda were greatly decreased. Dominant species was Baetis fuscatus of Ephemeroptera, numbers of species and individuals of Ephemeroptera, Plecoptera and Trichoptera(EPT group) were dramatically increased from 26 species, 110 individuals to 32 species, 365 individuals respectively. This suggests that the change of river bed and flow velocity due to heavy rain provided a suitable environment for the EPT group that preferred the rift of a stream. In the functional feeding group, only gathering collectors and filtering collectors were identified in autumn of 2017 because some functional groups preferentially adapted to the changed environment. The interspecific competition and environmental condition were the worst in autumn after heavy rain due to the increase individuals of some species. The ecological score of benthic macroinvertebrate community(ESB) was higher after the heavy rain than before. Results of the Group Pollution Index(GPI), Korean Saprobic Index(KSI) and Benthic Macroinvertebrate Index(BMI) were similar to those before and after heavy rainfall. Therefore, ESB was the most discriminating method for estimating the biological water quality in this study. Some species that are sensitive to water quality changes still appear or increase individuals in the area under investigation after the heavy rain. On the other hand, the individuals of some pollutant species decreased. This is thought to be because the habitat fluctuation caused by heavy rainfall has improved the water environment.

        Mood Effects on Performance Quality and Satisfaction

        Kim Hyoung-Gon(김형곤),Lee Choong-Ki(이충기),Chon Jin-Hyung(전진형),Byun Jeong-Woo(변정우) 대한관광경영학회 2009 觀光硏究 Vol.24 No.4

        본 연구에서는 구조모형을 통하여 기분(mood), 인지된 수행품질, 만족도, 그리고 충성도와의 상호관계를 검증하고자 하였다. 특히, 축제의 다양한 속성에 대한 인지적 평가와 구매 후 태도에 영향을 미치는 기분의 역할에 초점을 맞추었다. 본 연구에서 제시된 모형을 평가하기 위하여 부천국제판타스틱 영화제에 참석한 방문객들을 대상으로 설문조사를 실시하였다. 이론적 모형에서 제시한 변수들간의 추론된 관계들은 연구의 결과를 통하여 입증되었다. 무엇보다도 축제방문객들의 기분은 인지된 축제의 수행품질에 긍정적인 영향을 미치는 것으로 나타났고, 만족도와 충성도에는 인지된 수행품질평가를 통해 간접적으로 영향을 미치는 것으로 나타났다. 또한, 이론적 모형에서 제시하고 있는 수행품질의 직접적인 영향도 본 연구에서 입증되었으며, 분석결과와 연관된 이론적 시사점도 향후 연구방향과 더불어 제시되었다. This study examines the relationship between mood, performance quality, satisfaction, and loyalty. A structural model was developed to specify interrelationships between these variables. A particular emphasis was given to the role of mood in shaping cognitive evaluation of festival attributes and post-purchase attitudes satisfaction and loyalty. Visitors at Puchon International Fantastic Film Festival were surveyed to test the proposed model. The results of study confirm the hypothesized relationships between the variables. First of all, it was found that mood positively influenced performance quality. As hypothesized, mood indirectly affected satisfaction and loyalty via the performance quality. The direct effects of performance quality were verified in this mode. Theoretical implications associated with the results were discussed along with future research suggestions.
