    윤종학 , Jung-Soo Park , Jong-Yun Choi and 1 other persons | 2017, 26(5) | pp.291~302 | number of Cited : 3
    Abstract PDF
    The research was carried out in order to find climate factors which determine the distribution of Eurya japonica, and the potential habitats (PHs) under the current climate and climate change scenario by using species distribution models (SDMs). Four climate factors; the warmth index (WI), the minimum temperature of the coldest month (TMC), summer precipitation (PRS), and winter precipitaion (PRW) : were used as independent variables for the model. Seventeen general circulation models under RCP (Representative concentration pathway) 8.5 scenarios were used as future climate scenarios for the 2050s (2040~2069) and 2080s (2070~2099). Highly accurate SDMs were obtained for E. japonica. The model of distribution for E. japonica constructed by SDMs showed that minimum temperature of the coldest month (TMC) is a major climate factor in determining the distribution of E. japonica. The area above the -5.7℃ of TMC revealed high occurrence probability of the E. japonica. Future PHs for E. japonica were projected to increase respectively by 2.5 times, 3.4 times of current PHs under 2050s and 2080s. It is expected that the potential of E. japonica habitats is expanded gradually. E. japonica is applicable as indicator species for monitoring in the Korean Peninsula. E. japonica is necessary to be monitored of potential habitats.

    Recent Ecological Asset Research Trends using Keyword Network Analysis

    Kim, Byeori , 이재혁 , Kwon, Hyuk Soo | 2017, 26(5) | pp.303~314 | number of Cited : 6
    Abstract PDF
    The purpose of this study was to determine domestic and foreign ecological asset research trends. We aimed to understand ecological assets research directions and trends by comprehensively analyzing 12 keywords, including those similar to keywords for comparable assets, to identify related fields and regions. Extensive analysis of domestic and foreign studies was conducted through keyword network analysis of textural information. This approach is helpful for understanding the flow of information and identifying research directions. Foreign studies based on sustainability were connected with ‘Economic assessment’, ‘Management’ and ‘Policy’ areas. It was difficult to determine domestic research trends because there are fewer domestic studies than foreign. There were studies that sought to identify economic value of developing regions. This research can be used to guide the research direction for future ecosystem asset analysis in Korea.

    이도훈 , Choi Chul Hyun , Young-Chae Kim and 2 other persons | 2017, 26(5) | pp.315~330 | number of Cited : 0
    Abstract PDF
    The aim of this study is to examine the damage of plants in the islands due to the habitat and feeding of European rabbit (Oryctolagus cuniculus) and to suggest future management plan. The survey area Beomseom Island is found to be a vegetation distribution type that was formed secondary by the exposure of artificial interference except for evergreen vegetation distribution and European rabbit showed high habitat track density mainly in the lumbering area. Kkamakseom Island was identified as a severe vegetation distribution area due to interference, and European rabbit showed high habitat track density around deciduous broad leaved forests. Feeding plants of European rabbit was identified as a total of 12 families 17 breeds. Total 9 families 11 breeds were found in Beomseom Island while 5 families 6 breeds were found in Kkamakseom where most available food resources were loss to European rabbit. As for vegetation index of Beomseom Island, about 6.6% of total island area was declined and the vegetation index of Kkamakseom Island was reduced at most area of the island. In Kkamakseom Island, the area where EVI decreased to less than -0.008 unit/yr was reduced to 5.2%, and the area where it was reduced to -0.008 to -0.006 unit/yr in total was 13.32% of the total area. Thus, it was estimated to be seriously damaged by vegetation. Therefore, immediate management is required.

    Water Quality Impact Assessment in Korea – Comparing with the Integrated Control of Pollutant-Discharging Facilities –

    Lee, Jong-Ho , CHO JAE HEON | 2017, 26(5) | pp.331~343 | number of Cited : 1
    Abstract PDF
    The important changes in water environment management in Korea can be summarized as the enactment of Act on the Integrated Control of Pollutant-Discharging Facilities. Therefore water quality impact assessment should be reexamined and be revised. This study examines the present water quality impact assessment items (permissible discharge limits, standards for effluent water quality including Total Pollutant Load Management System) and considers the land use regulation for water quality conservation and NVZs(Nitrate Vulnerable Zones of EU and England). It also considers lately adopted standards(maximum discharge standards, permissible discharge standards, and marginal discharge standards etc) based on Act on the Integrated Control of Pollutant-Discharging Facilities and then compares Korean BAT and its counterpart control technology of U.S.A. And it also compares the items of water quality impact assessment with those of Integrated Control of Pollutant-Discharging Facilities, based on EIS reporting items. This study suggests five improvement measures for water quality impact assessment. First reflection of discharge impact analysis on impact prediction and assessment, second reflection of permissible discharge standards on agreed standards in the EIA procedure, third, reflection of diversified BAT on mitigation measures in the EIA procedure, forth introduction of land use regulation such as NVZs, finally strengthening linkage between water quality items and land use items etc.

    Evaluation of Gravity Ceramic Filter as Household Purifier: Using Clay & Red Soil in the Northwest of Cambodia

    Kim, Youn-Kwon , Sungpil Kim , Wooseok Cho and 1 other persons | 2017, 26(5) | pp.344~353 | number of Cited : 1
    Abstract PDF
    Cambodia is a typical country that a very famous tourist destination in South Asian regions, but water has some serious problems. As a public hygiene point of view, water problems in Cambodia can be roughly classified into two categories. A numbers of the report revealed that thermotolerant coliform(TTC) bacteria and arsenic(As) pollution representative species as a representative pollutant for surface water and ground water problems, respectively. In recent years, home water purifier systems for various filter systems including BSF(Bio-Sand Filter), MF and RO have been spread and adopted in rural areas. However, BSF and composite membrane processes are recognized as an undesirable and representative method due to unreliable efficiency, high cost and maintenance issues. In order to develop a small-scale ceramic filter as a home water purifier, the applicability of two types of gravity ceramic filter using clay and red soil in the part of the Northwest was made and compared in this research.

    Abstract PDF
    Considerable amount of resources on roads, basic infrastructure, to promote economic development and distribution of goods is invested. Despite the necessity, its undesirable side effects are various environmental problems In order to efficiently evaluate these problems more than before, planning indictors for environment-friendly road constructions is proposed in this study. First, we make an investigation into real-life cases where the extracted planning indicators were applied. Second, it is suggested that an alternative assessment method efficaciously evaluate and/or adopt extracted planning indictors on road construction projects. Finally, criteria to determine environmental impacts with respect to planning indicators and apply them into real cases is proposed. This study has its significance in upgrading past pro-environmental indictors for road construction, suggesting reasonable applications of planning indicators, and setting criteria to determine environmental impacts based on planning indicators.

    Omme Kulsum Nayna , Lee, Sang-Don | 2017, 26(5) | pp.376~384 | number of Cited : 0
    Abstract PDF
    Bangladesh is a South Asian country with subtropical monsoonal climate between the intersection of the Indo-Himalayan and Indo-Chinese sub-regions, is known as biodiversity hotspot of the Asian region. The country has different types of forest like deciduous forest, evergreen forest, mixed forest, haor (wetlands) and mangrove forest. The natural beauty of the country is increased with the presence of so many rivers, longest sea beach of the world, green plants, critical hilly regions and green agricultural forest widely spread here and there. Sundarbans is the world largest mangrove forest and world natural heritage site declared by UNESCO in 1999 situated in Bangladesh and India. About 62 percent of this mangrove forest is situated in Bangladesh and there are so many plants and animals are found in this forest. To meet the increasing demand of the large population most of the natural ecosystem is now altered, deforestation rate is increased, natural habitat of the species is disturbed. Due to the imbalance of the climate and natural system many of the rare species of the world found this region is now endangered and some of the species are extinct. Directly or indirectly they are benefited from natural resources. At present time community, based ecotourism is also an important source of income for rural poor peoples. To protect the natural resources the government is now developed so many conservation acts and policy as well NGOs are also doing work for the conservation of ecosystem and biodiversity. At present transboundary pollutants and so many natural disasters also destruct the natural resources of Bangladesh.
