    Abstract PDF
    A wide range of projects for ocean renewable energy are currently in development aroundthe world and ocean energy industries continue to receive significant support from their governments. Surrounded by sea on three sides, Korea has potentially abundant renewable ocean energy resources,which include tidal current, tidal range, offshore wind power, osmotic pressure and ocean thermalenergy. Numerous ocean renewable energy projects has been developed in Korea. Nevertheless, thereare some concerns that those developments often select an environmentally unsuitable location and/orthere are very few existing information on those environmental effects. The purpose of this study is to improve supporting policies and regulation systems of ocean renewable energy development in Koreaby reviewing and compiling government policies and environmental assessment systems related toocean renewable energy development around the world. The study suggests several policyimplications for its environmental-friendly development in Korea, including requirements of strategicenvironmental assessment for proactive and environmentally suitable site selection of ocean renewableenergy development and continuous post-development environmental monitoring, and so on.

    오현경 , Choi, Yoon-ho , You Ju Han | 2014, 23(4) | pp.251~270 | number of Cited : 13
    Abstract PDF
    The purpose of this study is to offer the basic data and method for assessing the naturalinessof temple environment by applying the ecological index of plant to quantitatively and objectivelyassess the flora and to understand the flora distributed in major temple forest. The ecological index of plant was based in the surveyed flora. The whole flora were summarized as 535 taxa including 103families, 310 genera, 426 species, 5 subspecies, 82 varieties and 22 forms. And, the numbers of taxa inthe Beopheungsa were 267 taxa, 314 taxa of the Daeseungsa and 296 taxa of the Seongjusa. The rareplants were 9 taxa including Aristolochia contorta, Viola albida, Arisaema heterophyllumand so forth, andthe Korean endemic plants were 11 taxa including Clematis trichotoma, Stewartia pseudocamellia, Viciachosenensis and so forth. The specific plants by floristic region were 51 taxa including Wistaria floribunda,Celtis aurantiaca, Angelica gigas and so forth, and the pteridophyta were 26 taxa including Osmundajaponica, Polystichum braunii, Onoclea orientalis and so forth. The naturalized plants were 35 taxaincluding Fallopia dumetorum, Conyza canadensis, Xanthium strumarium and so forth, the invasive alienplants were 3 taxa including Ambrosia artemisiifolia, Aster pilosus and Eupatorium rugosum. In the resultsof analysing the ecological index of plant in whole temple forests, RI(Rare Index) was 1.7%, 2.1% ofEI(Endemic Index), 9.5% of SI(Specific Index), 1.2 of PI(Pteridophyta Index) and 6.5% of NI(NaturalizedIndex) in narrow sense. In broad sense, FI(Flora Index) was 11.0%, 1.5% of RI, 3.4% of EI, 4.8% of SI,10.1% of PI, 10.9% of UI(Urbanized Index) and 25.0% of DI(Disturbed Index). The FI of the Daeseungsawas the highest among the three temple forests. In narrow sense, the RI, SI, NI and DI of theBeopheungsa was high, the seongjusa was higher the EI and SI. In broad sense, the RI and SI of theBeopheungsa, the EI, SI and PI of the Seongjusa, the UI is high in the Daeseungsa. In future, if we willanalyze ecological index of plant in other temple forests, we will offer the help to establishing the planof conservation and restoration on ecosystem in whole temple forests.Environmental Specimen Banks(ESBs) are playing pivotal role in monitoring the effect of environmental pollution on the ecosystembased on the retrospective analysis of the representative samples collected regularly and stored incryogenic condition.

    Microhabitat Analysis of Endangered Species (I), Cobitis choiiwith Rapid Decreases of Population by Environmental Pollution for a Habitat Replacement

    Ji Yoon Kim , Kwang Guk An | 2014, 23(4) | pp.271~284 | number of Cited : 1
    Abstract PDF
    The objectives of this research were to analyse the microhabitat of Cobitis choii which isdesignated as an endangered fish species (I) and national monument species in Korea (No. 454), andprovide valuable information of suitable replacement habitat in the future for a conservation of thepopulation with rapid decreases by environmental pollution. Sampling and microhabitat analysis inthree streams such as Baekgok, Yugu and Gap Stream, known as one of the least habitats in Korea showed that the mean number of Cobitis choii observed was 2.6. This result indicated that the richnesswas too low, so the species conservation was very urgent. Optimal physical microhabitat of thepopulation was determined as environmental conditions with > 60% sand with 1 mm particle size,optimal water depth of 20 - 60 cm in the habitats, and the optimal current velocity of < 0.4 m/s. Underthe circumstances of the microhabitat, optimal water volume (discharge) was 0 - 2 m3/s in the eachsectional analysis and this reach was mainly composed of the stream section with intermittant slowruns and pools. These microhabitats were largely disturbed by physical modifications of habitat andchemical pollutions due to direct influences of nutrient-rich water inputs from the urban area andintensive agricultural pollutants. For these reasons, optimal habitat replacement are required in thefuture for the conservation of the species.

    Selecting probability distribution of event mean concentrations from paddy fields

    정재운 , 최동호 , Yoon, KwangSik | 2014, 23(4) | pp.285~295 | number of Cited : 6
    Abstract PDF
    In this study, we analyzed probability distribution of EMCs (Event Mean Concentration)of COD, TOC, T-N, T-P and SS from rice paddy fields and compared the mean values of observedEMCs and the median values of estimated EMCs (EMC50) through probability distribution. The fieldmonitoring was conducted during a period of four crop-years (from May 1, 2008, to September 30. 2011) in a rice cultivation area located in Emda-myun, Hampyeong gun, Jeollanam-do, Korea. Fourprobability distributions such as Normal, Log-normal, Gamma, and Weibull distribution were usedto fit values of EMCs from rice paddy fields. Our results showed that the applicable probabilitydistributions were Normal, Log-normal, and Gamma distribution for COD, and Normal, Log-Normal, Gamma and Weibull distribution for T-N, and Log-normal, Gamma and Weibulldistribution for T-P and TOC, and Log-normal and Gamma distribution for SS. Log-normal and Gamma distributions were acceptable for EMCs of all water quality constituents(COD, TOC, T-N,T-P and SS). Meanwhile, mean value of observed COD was similar to median value estimated bythe gamma distribution, and TOC, T-N, T-P, and SS were similar to median value estimated by lognormaldistribution, respectively.

    A Study on the Management System Improvement of Effluent Water Qualities for Public Sewage Treatment Facilities in Korea

    Dong-Hwan Jeong , 최인철 , Cho Yang Seok and 5 other persons | 2014, 23(4) | pp.296~314 | number of Cited : 6
    Abstract PDF
    In recent years, Ministry of Environment (MOE) has been implementing a phasedstrengthening of the effluent standards for sewage treatment plants. In this regard, a comprehensivesystem should be developed to help check the appropriateness of such standards by specifying thegrounds for standard-setting and investigating the current operation of sewage treatment plants clearly. It is necessary to establish a new standard-setting system for the effluent that is in a closerconnection with the environmental criteria and rating systems. In the United States, the federal government provides guidelines on the least provisions andrequirements for the Publicly Owned Treatment Works (POTWs). Local governments set the sameor stricter guidelines that reflect the characteristics of each state. In Japan, the sewage treatmentplants are subject to both the effluent standards and the discharge acceptable limits to pubic watersunder the sewerage law. Specific requirements and limits are set in accordance with localgovernment regulations. The European Union imposes sewage treatment plants with differentprovisions for effluent standards, depending on the sensitivity of public waters to eutrophication. The effluent standards for sewage treatment plants are classified by pollutant loads discharged toreceiving waters. MOE also needs to introduce systems for setting new parameter standards on a POTW effluentby applying statistical means and treatment efficiencies or optimal treatment techniques, as seen inthe cases of the US National Pollutant Discharge Elimination System (NPDES) or the EU IntegratedPollution Prevention and Control (IPPC).

    Abstract PDF
    After the modern industrial revolution, rivers in cities became covered and disappeareddue to the pressure to develop them. Likewise, their function which is to serve as the basis of naturalecology system in the cities began to be damaged. This research demonstrated that there are a total of268 categories when it comes to the list of plants, including 64 families, 179 genera, 230 species, 36varieties, and 1 subspecies. When the relative abundance of the plants that were found at the targetresearch site was studied, the secondary survey demonstrated Bromus japonicus 22.97, Artemisia princeps var. orientalis 16.76 and Erigeron annuus 15.69 while third survey demonstrated Digitaria ciliaris 26.78,Ambrosia trifida 16.29 and Aster pilosus 14.31. There were 54 species of naturalized plants that appeared. Analysis demonstrated annual plant 23 classification category (43%), perennial 11 classificationcategory (20%), multi-perennation 17 classification category (31%), woody plant 3 classificationcategory (6%) and others. When the naturalized plants that were found at the target research site wereanalyzed by the place of origin, North America and EU took up 76%, which accounts for 3/4 of the allthe naturalized plants. At the target research site, naturalization degree of 5 pertained to 22classification category (41%), which was the highest, followed by 19 classification category (35%) withnaturalization degree of 3, 8 classification category (15%) with naturalization degree of 2 and 5classification category (9%) with naturalization degree of 4 in the order mentioned. Flora ofJungnangcheon did not manifest any change compared to 10 years ago. Thus, it is necessary to increaseof biodiversity efforts to improve SeoulCity’s natural environment and cityscape.
