    Abstract PDF
    In order to analyze environmental impact of livestock manure and organic fertilizers, this studyinvestigated livestock-breeding and pollution loads, the status of individual and public livestockmanure treatment facilities, and the status of production, supply and components of compost andliquid fertilizers in the Nonsan area. Also, on a trial basis, this study investigated the life cycle ofthe environmental impact of livestock manure and its organic fertilizers on stream, groundwater,and agricultural soil. The results are as follows. Firstly, were detected the range of 0.13~1.32 μg/L of As, 0.004~0.467 μg/L of Cd and 0.5~9.2μg/L of Pb as a harmful substances which show lower concentrations than person preservationcriteria of water qualities and aquatic ecosystem. However, it is not clear that heavy metals affectenvironment such as stream, groundwater and agricultural soil. Secondly, this influence couldchange according to investigation time and treatment efficiency. As were detected large amountsof persistent organic pollutants(e.g. 14.24~38.47 μg/L of acetylsalicylic acid, 1.17~2.96 μg/L ofsulfamethazine, and 2.25~174.09 μg/L of sulfathiazole) in effluent from livestock farms and smallamounts of sulfathiazole(ND~1.63 μg/L) in the stream, it is necessary to monitor POPs atindividual and public livestock manure treatment facilities. However, significant environmentalimpact did not appear at groundwater and agricultural soil in the test area supplied with liquidfertilizers. These results could be applied to investigate the environmental impact of livestock manurethrough a comprehensive livestock manure management information system.

    윤종학 | 中尾勝洋 | Jung-Hyun Kim and 3other persons | 2014, 23(2) | pp.101~111 | number of Cited : 3
    Abstract PDF
    The research was carried out in order to find climate factors which determine the distributionof Neolitsea sericea, and the potential habitats (PHs) under the current climate and three climatechange scenario by using species distribution models (SDMs). Four climate factors; the minimumtemperature of the coldest month (TMC), the warmth index (WI), summer precipitation (PRS),and winter precipition (PRW) : were used as independent variables for the model. Three generalcirculation models under A1B emission scenarios were used as future climate scenarios for the2050s (2040~2069) and 2080s (2070~2099). Highly accurate SDMs were obtained for N. sericea. Themodel of distribution for N. sericea constructed by SDMs showed that minimum temperature ofthe coldest month (TMC) is a major climate factor in determining the distribution of N. sericea. Thearea above the -4.4℃ of TMC revealed high occurrence probability of the N. sericea. Future PHsfor N. sericea were projected to increase respectively by 4 times, 6.4 times of current PHs under2050s and 2080s. It is expected that the potential of N. sericea habitats is expanded gradually. N. sericea is applicable as indicator species for monitoring in the Korean Peninsula. N. sericea isnecessary to be monitored of potential habitats.

    A Study for Examination of Road Noise Prediction Results According to 3-d Noise Prediction Models and Input Parameters

    선효성 | 2014, 23(2) | pp.112~118 | number of Cited : 0
    Abstract PDF
    The application of a 3-d noise prediction model is increasing as a tool for performing actualnoise assessment in order to investigate the noise impact of the residential facility around adevelopment region. However, because the appropriate plans of applying a 3-d noise predictionmodel is insufficient, it is important to secure the reliability of the noise prediction results generatedby a 3-d noise prediction model. Therefore, this study is focused on examining a 3-d noiseprediction model, and a prediction equation and input data in it. For this, the 3-d noise predictionmodels such as SoundPLAN, Cadna-A, IMMI is applied in road noise. After the contents of roadnoise equations, input data of road noise source, and input data of road noise barrier areunderstood, the road noise prediction results are compared and examined according to thevariation of 3-d noise prediction model, road noise equation, and input data of road noise sourceand road noise barrier.

    KONG Wooseok | 김건옥 | 이슬기 and 2other persons | 2014, 23(2) | pp.119~136 | number of Cited : 17
    Abstract PDF
    This work aims to select the potentially vulnerable plant species against climate change at alpineand subalpine belts of Mts. Sorak, Jiri, and Halla, from central, southern, southern insular highmountains of the Korean Peninsula, respectively. The selection of global warming relatedvulnerable plants were performed by adapting various criteria, such as flora, endemicity, rarity,floristically specific and valuable species, species composition at mountain summits, horizontaland vertical ranges of individual species, and their distributional pattern in the Korean Peninsula. Line and quadrat field surveys along the major trails from all directions at height above 1,500meters above sea level of Mts, Sorak, Jiri and Halla were conducted each year during spring,summer, and autumn from 2010 to 2011. Based upon above mentioned eight criteria, high level of climate change related potentiallyvulnerable arboral plants, such as Rhododendron aureum, Taxus caespitosa, Pinus pumila, Oplopanaxelatus, Vaccinium uliginosum, and Thuja koraiensis are noticed from at subalpine belt of Mt. Sorak. Species of Abies koreana, Rhododendron tschonoskii, Oplopanax elatus, Taxus cuspidata, Picea jezoensis,and Juniperus chinensis var. sargentii belong to climate change concerned vulnerable species atsubalpine belt of Mt. Jiri. High level of climate change related species vulnerability is found atalpine and subalpine belts of Mt. Halla from Diapensia lapponica var. obovata, Salix blinii, Empetrumnigrum var. japonicum, Vaccinium uliginosum, Juniperus chinensis var. sargentii, Taxus cuspidata,Rhamnus taquetii, Abies koreana, Hugeria japonica, Prunus buergeriana, and Berberis amurensis var. quelpartensis. Countermeasures to save the global warming vulnerable plants in situ are required.

    이광열 | 장하라 | 윤영진 and 4other persons | 2014, 23(2) | pp.137~149 | number of Cited : 2
    Abstract PDF
    The purpose of this study is to investigate the dynamics of the Zacco platypus population amongstreams in the Gongjicheon water system, Korea from December 2010 to October 2011. In thisstudy, fish fauna was collected 27 Species belonged to 9 Families. The legal protection species,such as a natural monument and endangered species was not collected. Korean endemic specieswas collected 6 species including to Z. koreanus. The ratio of Korean endemic species was 22.6%,and it was lower than 51.3% that average of Korean endemic species in the Hangang water system. About these status, we considered that Gongjicheon water system had lost of the uniquecharacteristics of the Hangang water system by the anthropogenic disturbances. The result of analysis to length-weight relationship and condition factor(K) of Z. platypuspopulation in the Gongjicheon water system, the regression coefficient value(b) to indication ofgrowth degree of the population was 3.04 and the slope of the condition factor(K) to indication ofcorpulency had positive value, respectively. These results seems to be that the Z. platypuspopulation is maintained to a little unstably. In addition, the values of the degree of growth andcorpulence were very low than the other natural streams in the Hangang water system, so it considered that the many artificially stress factors are occurred in this study area. These resultsare similar to Fish Assessment Index(FAI) in the assessment for health of aquatic ecosystem. Therefore, we are considered to require precise investigation and sustained monitoring for therestorations of stream ecosystem in the Gongjicheon water system.

    Application of IUCN Category Regarding the Designation of Overlapping Protected Areas

    KIL SUNG hO | Lee, Dong Kun | Sung Hyun Chan and 4other persons | 2014, 23(2) | pp.157~167 | number of Cited : 1
    Abstract PDF
    The purpose of this study is to seek the application of IUCN categories of overlapping protectedareas which is legally designated in South Korea. Different government departments in South Koreahave managed and designated as protected areas. However, the protected areas due to differentmanagement agencies can be confused with restricting behaviors and supporting residents. The IUCN presents the reasonal standardization classifying the protected areas which could beapplied all over the world. Six categories issued by the IUCN could be applied to deal with theproblems of the overlapping protected areas. We suggested the application of the IUCN categoriescompared with legal frame in South Korea. Most areas are overlapped in designation, but the areasare important for ecology and landscape. Moreover, each protected areas in South Korea havezone districts. Comprehensively considered all these things, we made rationale matrix correlatedwith the IUCN categories and the zone districts of the protected areas in South Korea. For theresult of this study, this matrix could be helped to the application of the IUCN categories indomestic protected areas. Although the protected areas has been recognized as regulatory regions,it is expected to expand and sustain the areas based on the matrix.
