The grid cell analysis is used to select good sites as habitats at the region. The northern area of Yeongjong Island, Incheon has been disturbing by habitat loss due to human activities such as residential development, deforestation. In order to determine significant places as bird habitats and to select conservation areas at this island, the study area was divided into 70 grid cells(500 ×500m each grid) and then each grid was ranked by spatial analysis using the species diversity index. Fieldwork was carried out in Spring and Autumn of 2010. To examine grid cells which were ranked high in both seasons in common, we used the average ranking value, combined data from two seasons. This area consists of mainly agricultural areas and forests(more than 68%) among eight habitat types: the agricultural land, forest, coast, lake, meadow, stream, city and other things. A total of 110 species was recorded: 4,183 birds of 102 species in Spring and 3,326 birds of 58 species in Autumn. In other words, the number of individuals and species was higher in Spring than in Autumn. Species diversity index presented the highest value at M8 grid cell in Spring(3.380) and at A4 gird cell in Autumn(2.736). In 18 of 22 grid cells where the average ranking value was higher than 3, the forest was distributed and in 4 grid cells, the coast and wetland were widely distributed, in which theses were located apart from humanassociated disturbances such as construction works for a leisure complex. Our results present a new estimate method not only to minimize loss of bird habitats but also to conserve important habitats when the large-scale development takes place at particular region.

본 연구를 위하여 인천광역시 옹진군 영흥면 영흥도에서 2006년부터 2009년까지 봄, 여름, 가을의 3계절 조사를 정기적으로 수행하였고 조사지역은 도로에 따라 4개 지역으로 구분하였다. 각 지역의 서식지유형은 농경지, 산림, 하천, 호소, 해안 중 3~4개의 유형으로 분류되었다. 조사지역에서 관찰된 종은 총 92종이었다. 서식지유형에 대하여 조사지역별, 연도별, 계절별 종수, 개체수, 종 다양도, 종풍부도를 분석한 결과, 농경지는 4개의 조사지역에서 조류의 종 구성이 일정한 양상을 띠고 있지 않았다. 이것은 농경지에 서식하고 있는 종이 주변 다른 서식지의 영향을 받고 있기 때문인 것으로 판단되었다. 농경지와 산림은 계절별로 서식하는 종 구성이 서로 달랐으나 하천과 해안은 서로 유사한 양상을 나타내고 있는 것으로 분석되었고 호소는 매년 가을에 월동을 위해 오리류가 주를 이루며 서식하고 있는 것으로 조사되었다. 모든 지역에서 2006년부터 2009년까지 4년간 연도별로 종 및 개체수, 종다양도, 종풍부도 모두 거의 비슷한 양상을 나타내고 있었으나 서식지 면적과는 유의하지 않은 상관관계로 분석되어, 면적에 따른 먹이원의 분포 변화로 인한 종 및 개체수의 변동 등과 같은 추가 요인에 대한 조사가 면밀하게 수행되어야 할 것으로 판단되었다. This study was conducted with a regularly seasonal survey of spring, summer and autumn from 2006 to 2009 in Youngheung Island. The survey area was classified into 4 areas by road, each regional habitats types (agricultural land, forest, stream, lake, coast) were divided into the 3-4. We observed a total 92 species of birds in 4 areas. To investigate each regional habitats types, we analyzed number of species and individuals, species diversity and richness according to annual and seasonal types. The result showed that agricultural land was distributed in all of 4 areas, and the characteristics in birds distribution of 4 areas were not taken on a certain aspect. It was considered to be affected by another of habitats close to agricultural land. Agricultural land and forest seasonally varied composition of birds, which act as a significant proportion of the inhabitation at summer, winter and passage birds than this of resident birds. Seasonal species composition of stream and coastal habitats was analyzed similar patterns. The large number of wintering Anatidae was observed at lake in yearly fall. Number of species and individuals, species diversity and richness in all regions during four years from 2006 to 2009 shows a similar pattern, but the habitats area found that it was not correlated. However preys and other distributions are changed by habitats area. So changes of species and population by variety habitats area must be additionally investigated.

This study examined the relative effects of feedback frequency and specificity of Eco-IVIS(eco in-vehicle information system) on the fuel-efficiency and workload. Eighty participants randomly assigned into four experimental groups (high frequency/specific, high frequency/global, low frequency/specific, and low frequency/global feedback) and they drove 16.4Km motorway under the each feedback condition. The dependent variable were fuel efficiency and Drive Activity Load Index which measured participants’ subjective ratings of driving workload. The results showed that high frequent feedback was more effective for increasing fuel-efficiency than low frequent feedback, however, there was no significant difference of fuel-efficiency between specific and global feedback. Although, overall DALI score was comparable among four experimental conditions, visual demand score was significant higher under the high frequent feedback condition than low frequent feedback.

We were interested in the long-term temporal and spatial variability trends of water quality. Trend tests, such as the Seasonal and Regional Kendall tests and LOWESS (LOcally WEighted Scatter-plot Smoother), have been recommended as outstanding tools for trend detection. In this study, we conducted four types of nonparametric trend tests (Seasonal and Regional Kendall tests, LOWESS, and flow-adjusted Seasonal Kendall). We aimed to identify water quality trends using the monthly data for five variables (BOD, COD, TN, TP, and flow) collected from 24 sites in the Nakdong River from August 2004 to December 2013. According to the Regional Kendall test, BOD, COD, and TN increased but TP decreased trend. The Seasonal Kendall test showed that BOD, TN, and TP remained constant at 62.5-83.3% of the sites. COD remained constant at 58.3% of the sites. LOWESS showed that TP gradually increased between 2007 and 2008, then decreased slowly at the Gumi, Geumhogang6, Daeam-1 and Milyanggang3 sites. BOD increased slightly between 2008 and 2009, and then decreased slowly at the Namgang4-1 site. Lastly, a flow-adjusted Seasonal Kendall test was conducted. There were different results from the Seasonal Kendall and flow-adjusted Seasonal Kendall tests at 11 of the 24 sites. According to the results from six of the eleven sites, BOD increased at one site, showed no trends at three sites, and decreased at two sites. Each of COD, TN increased at two, and one site. but TP decreased at two sites.

본 연구는 화엄늪 습지보호지역에서 식생의 공간적 분포특성을 파악하고 올바른 식생학적 보전 및 복원 방안을 제시하고자 시행하였다. 식생자료는 2008년과 2013년에 Braun-Branquet의 방법을 적용하여 총 117종(미동정종 포함)의 식물종이 포함된 29개가 획득되었다. 식물군락은 총 8개로 구분되었으며, 수분조건에 따라 건생형(신갈나무-애기감둥사초군락, 산철쭉군락-전형하위군락, 참억새하위군락, 미역줄나무군락)과 습생형(진퍼리새군락-전형하위군락, 왕미꾸리꽝이하위군락, 참억새하위군락, 바늘골-끈끈이주걱군락)으로 나누어졌다. 습생입지에 발달하는 습생형은 습지보호지역 내에서 보호의 핵심 대상으로 습지의 함몰된 공간 또는 물골 주변에 주로 발달하였다. 면적은 습생형이 전체의 약 3.8%에 불과하였으며, 습지보호지역 안에서 참억새가 우점하는 건생형이 약 51.5%로 가장 넓게 분포하였다. 습지보호지역 내에 다양한 수목들이 침투해 있었다. 2008년에는 교목성 수종 8종(총 228개체)과 관목성 수종 6종(총 51개체)을 포함하여 총 14종의 침투식물들이 관찰되었으며, 2013년에는 오리나무 2개체가 생육하는 것이 확인되었다. 화엄늪의 지속적인 보전과 관리를 위해서 식생유형, 공간분포 변화 및 침투식물에 대한 지속적인 모니터링, 핵심·완충·전이지역의 구획화 관리 등을 통한 능동적이고 가변적인 설정방안 모색을 제안하였다. This study was carried out to understand the spatial distribution and conservation, restoration plan for vegetation in the Hwaeom wetland protected area. Total 29 phytosociological releves consisted of 117 plant species (unidentified species contained) was made during field studies conducted at 2008 and 2013 applying Braun-Branquet method. The collected vegetations were arranged 8 plant communities and thus divided hydric types (Drosera rotundifolia-Eleocharis congesta community, Carex forficula-Molinia japonica community) and xeric types (Miscanthus sinensis community, Rhododendron yedoense var. poukhanense community, Tripterygium regelii community, Carex gifuensis-Quercus mongolica community) under moisture conditions. The hydric types growing in hydric conditions distributed along hollowed out ground or the water channel that have a key qualification to protect. In the wetland protected area, the hydric vegetation types were mostly covered about 3.8% and the xeric types dominating by Miscanthus sinensis were most wildly distributed about 51.5%. Various woody plant species invaded the place. In 2008, invasion plants observed with total 14 species - 8 tree species (227 individual), 6 shrub species (51 individual) and alders (Aluns japonica) found in 2013. We suggested finding out that the sustainable conservation and management in Hwaeom wetland should be setting up plan focused on activity and variability such as continuous monitoring (changing vegetation types, spatial distribution, invasion plants) and zonation management (core zone, buffer zone, transition zone).

Organic carbon and nitrogen stable isotope ratios of particulate organic matter (POM) were determined at 7 stations (6 stations in Han river and Paldang dam outflow station) from May to October 2013, in order to understand the origin of POM at the Han river. δ13C values of POM in four stations showed significant seasonal changes season, but δ15N values were enriched in around Kyeongan stream (K). POC, PN and Chl-a concentration showed a similar seasonal pattern in Kyeongan stream, with an apparent decrease from July to August. POC and PN concentration has a higher correlation with Chl-a concentration in Kyeongan stream (K). δ13C and δ15N values of POM has a lighter value during lower Chl-a concentration peroid, compared to other seasons. Our results revealed that Kyeongan stream (K) seemed to be influenced by substantial amount of organic manure or fertilizer input in 2013, compared to the previous year (2012). These results suggest that the analysis of stable isotope ratios is a simple but useful tool for the identification of organic matter origin in aquatic environments
