    A Study on the Development Limit of Cheongju Downtown based on Environmental Carrying Capacity

    이승철 , Ha, Sungryong | 2009, 18(1) | pp.1~9 | number of Cited : 2
    Abstract PDF
    Even though the center of Cheongju city needs redevelopment because of a doughnut phenomenon, it has to be permitted within the environmental carrying capacity like a target water quality proposed on the Total maximum daily loads(TMDL) of Musim and Miho river watersheds. The aim of in this study is to identify the limit of redeveloping Cheongju downtown after analyzing its environmental carrying capacity using QUAL2E model. As a result of modeling various scenarios, the water quality of Musin river was shown that BOD5 is 2.3mg/L which is the target water quality in the double of existing development plan of the Cheongju downtown. The water quality of Miho river was BOD5 3.97mg/L which is less than the target water quality of Miho B watershed in the same condition. Therefore, this means that the limit of redevelopment within the environmental carrying capacity of cheongju downtown was estimated to be the double of existing development plan.

    A Case Study of Health Impact Assessment on Incinerator Construction Project - Human Risk Assessment due to Inhalation Exposure to Heavy Metals -

    Youngha Kim , 최상기 , Youngsoo Lee | 2009, 18(1) | pp.11~19 | number of Cited : 3
    Abstract PDF
    We conducted human risk assessment due to inhalation exposure to heavy metals emitted from incinerator. The process of health impact assessment(HIA) on incinerator is as follows: The first step is to presume and calculate the amount of heavy metals emitted using emission factor. The second step is to conduct an exposure assessment using the K-SCREEN model which is used for predicting the concentration in a conservative method. The last step is to carry out a risk assessment on carcinogenic and non-carcinogenic substances. This study revealed that rank of carcinogenic human risk was Cr+6 > As > Ni > Cd, and values of human risk assessment on carcinogenic and non-carcinogenic substances is lower than the US criteria for risk assessment except Cr+6. It is expected that the technique of HIA, especially human risk assessment on heavy metals, would be applied to the incinerator construction project. In addition, more systematic studies are needed to overcome some weak points and limits found in this study.

    A Study on the Plan for Advanced Noise-Policy in the 21st Century

    Geun-Ho Yang , Park Young Min , Nae-Hyung Lee and 1 other persons | 2009, 18(1) | pp.21~30 | number of Cited : 1
    Abstract PDF
    The study show that things about the noise control are indicated at The Noise & Vibration Control Act and the other Act. Also, the details program and total government ministries’ program for the noise control are indicated what are the advance noise control plan. The study consist of the four part which are「 Draw up the environmental noise infrastructure plan; the install shall be done the noisemap & the automatic noise measurement devices」, 「Resetting of environmental noise standard at the application area and Introduce of indoor noise; the guide for region classification of the noise standard & indoor noise」,「 Setting of aircraft noise standard and Program of measurement point operation; the noise-assessmentstandard shall change from WECPN to new index(Lden, Ldn, LAeq 24h) & the operation and control of aircraft noise measurement changes from local environmental office to central control center」and 「The method of noise regulation at construction site and the plan on making of standard for vibration regulation; It shall be made that the guideline of construction noise should include a target-construction, noise standard etc & the ministries shall unify control about construction vibration of the blasting vibration」. The advance noise-policy will improve efficiency to deal with civil appeal & damage on residents about noise.

    The Distribution Analysis of PM10 in Seoul Using Spatial Interpolation Methods

    Hong-lae Cho , Jeong, Jong Chul | 2009, 18(1) | pp.31~39 | number of Cited : 13
    Abstract PDF
    A lot of data which are used in environment analysis of air pollution have characteristics that are distributed continuously in space. In this point, the collected data value such as precipitation, temperature, altitude, pollution density, PM10 have spatial aspect. When geostatistical data analysis are needed, acquisition of the value in every point is the best way, however, it is impossible because of the costs and time. Therefore, it is necessary to estimate the unknown values at unsampled locations based on observations. In this study, spatial interpolation method such as local trend surface model, IDW(inverse distance weighted), RBF(radial basis function), Kriging were applied to PM10 annual average concentration of Seoul in 2005 and the accuracy was evaluated. For evaluation of interpolation accuracy, range of estimated value, RMSE, average error were analyzed with observation data. The Kriging and RBF methods had the higher accuracy than others.
