    Seung-Hwa Yoo , 정화영 , Gyung-Soon Kim and 6 other persons | 2015, 24(4) | pp.301~316 | number of Cited : 3
    Abstract PDF
    The endangered species, The Red-crowned Crane and the White-naped Crane are vulnerable species to the disturbance for human beings. We examined the importance of CCZ for the cranes by comparing the crane’s density in some CCZ-released areas, which are cranes’ wintering site in Cheorwon. We also assessed influence of disturbance such as construction and greenhouses on core habitats of cranes. Our study results suggested that the construction and reclamation in the CCZ shrunk core habitat area while increasing core area of far from the construction and reclamation area. The CCZ has been set since March, 2011 and the number of greenhouse has rapidly increased after 2012. As the number and size of greenhouse in the area where designation of CCZ was cancelled increased, foraging area of cranes diminished. Although the area where designation of CCZ was cancelled seemed to have more human disturbance than CCZ, the foraging density of cranes did not decline and even that of white-naped cranes increased. This could be the influence of artificial food supply at their roosting site. In conclusion, if the area of CCZ decline continuously in the future, density of cranes would decrease.

    Sungchan Yeum , Eungkyoon Lee | 2015, 24(4) | pp.317~331 | number of Cited : 2
    Abstract PDF
    A major barrier to the spread and vitalization of renewable energy lies in its economic infeasibility. And yet, there is a disparity in estimating the economic feasibility between supply and demand sides. Taking this into account, we calculate an appropriate level of mini-solar panel subsidies provided by the Seoul metropolitan government. More pointedly, this research investigates the receptivity and social equity of the subsidy program based on the analysis of the program’s financial feasibility. The results show that the subsidies can have anticipated effects for the heavy electricity consumption group but not for the low electricity consumption group. Specifically, estimated pay-back periods for groups of 401kWh ~ 500kWh (per month) users, 201 kWh ~ 400kWh users and 101kWh ~ 200kWh were approximately 5years, 8 ~ 9 years and 12 years, respectively. This implies that differential scales of the subsidies can better contribute to reducing regressive difference between the groups and meeting the goal of social equity in regards to energy justice.

    A Research on the Relationship between the Perception of Administrative Regulation and Odor Acceptance among Residents who live in Ochang Industrial Complex Area

    Park Sung-sik , Jung, Ju-yong , lk-jun Yeon | 2015, 24(4) | pp.332~343 | number of Cited : 3
    Abstract PDF
    It would be the most effective way to have government take care of social problems and hazardous material danger due to odor. It is also well known that odor acceptance and their willingness to pay for resolving the odor problem vary person by person. This is why public sector’s intervention is required to get ride of any possibility of market failure resulted from negative external effect of human. This paper has tried to do empirical research based on survey of residents who are currently living in the area of Ochang industrial complex in North Chong-chung province. According to the empirical research results, first of all, it was proven residents’ perception of legal regulation has a negative effect on odor acceptance. That is, the more residents are aware of law and regulation, the less they tend to accept odor. In addition, resident’s perception on need to improve odor regulation has a positive impact on their odor acceptance. Finally, residents’ satisfaction on the legal complaints to local government has an interaction effect to causative relationship between the perception of improving odor regulation and odor acceptance.

    Improved Migration of Arsenic by Bio-Electrokinetics in Soil

    KIM HONG TAE , Tae-Ryong Lee | 2015, 24(4) | pp.344~351 | number of Cited : 0
    Abstract PDF
    In this study, bio-electrokinetics was used to increase migration of arsenic by activating endemic microorganisms in the soil. In this technology, bio-electrokinetics which the cultured soil microorganisms and nutrients injected combines with biological technology. This technology using electrical movement of microorganisms could overcome the weakness of late degradation speed and low removal efficiency. And, various soil microorganisms reduce ferreous, manganese, etc., using organic matter by as an electron donor by injecting mixture of soil microorganisms and nutrients instead of using electrolyte of the electrode. Accordingly, surrounding metal oxide microorganisms convert arsenic (III) to arsenic (V) to increase migration of arsenic (III), in consequence, migration of arsenic increased in 60 to 70% compared to about 30% of conventional electrokinetics.

    Jeong, Jong Chul | 2015, 24(4) | pp.367~374 | number of Cited : 1
    Abstract PDF
    To examine the effect of thermal discharge from nuclear power plants, Sea Surface Temperature (SST) is one of the most important variables measured by satellite remote sensing. However, the study was not much comparison of field data and satellite SST from operational Landsat 8 Thermal Infrared Sensor(TIRS) and Landsat 7 ETM+. The Landsat 8 TIRS have 2 spilt Thermal Infrared channels but ETM+ uses one channel for extracting of SST. In spite of that this research carried out that Landsat 7 ETM+ have more profitable for correction of SST than Landsat 8 TIRS. The used 15 Landsat 7 and 8 Thermal Infrared data of path/row 114-36 were processed by SST algorithm of ENVI and IDL. The in-situ SST data from KHOA(Korea Hydrographic and Oceanographic Administration) compared with satellite SST and the accuracy of extracted SST were assessed by each field sites in-situ point data with time series satellite SST.

    Hanna Cho , Park, Joo-Yang | 2015, 24(4) | pp.375~385 | number of Cited : 1
    Abstract PDF
    This study analyzed international case studies on Strategic Environmental Assessment (SEA) follow-up and suggested implications based on the study’s findings to aid implementation of SEA follow-up in Korea. SEA requires follow-up in order to identify unforseen adverse effects and enable appropriate remedial action to be taken. Tool kits and methodological framework for effective SEA follow-up are only being researched recently. Based on the study’s findings, following implications for implementing SEA follow-up in Korea were drawn. First, the system of carrying out SEA follow-up would be different depending on the PPP topic. During the scoping stage, significant impacts should be identified according to the PPP topic, and thus help determine the indicators to be developed in the later stage. Secondly, responsibility, method, time, intervals and actions from SEA follow-up may vary depending on the target SEA consultation. Thirdly, the indicators of SEA follow-up may be considered together with various environmental standards and current political, social and economic indicators which are a big issue in society. Fourthly, SEA follow-up can be used as an integration system of its target planning and environmental planning. Finally, SEA feedback system should be needed. The result of SEA follow-up should be used for target PPP. These would lead to improvements to the target PPP. If SEA follow up is successfully implemented and actively carried out for domestic PPPs, Korea can be a step closer to realization of sustainable development.

    Dong-Hwan Jeong , Cho Yang Seok , 최인철 and 3 other persons | 2015, 24(4) | pp.386~395 | number of Cited : 0
    Abstract PDF
    In order to assess sewage treatment technology necessary to achieve water quality criteria in the watershed and to ensure best treatment technology is applied in building and expanding PSTWs when establishing the Watershed Sewer System Maintenance Plan, it is necessary to develop assessment guidelines to determinate the best treatment technologies applicable to the public sewage treatment works(PSTWs). Sewage treatment technologies such as anaerobic-anoxic-aerobic treatment process are employed at PSTWs, and treatment efficiency varies due to many factors such as how the PSTWs are operated. Therefore, analyzing assessment guideline of best available technology(BAT) using currently in USA and EU, this study presents assessment parameters for the assessment guidelines to be used in determining the best treatment technologies applicable to PSTWs. We have a plan to implement pilot assessment in preparation for the final assessment guidelines based on the results of professionals survey and to determine weighted factors and assessment parameters using analytic hierarchy process (AHP).
