    Study on the Ratio of Greenness in Residential Complex Development inthe Process of Prior Environmental Review System

    김성옥 , Lee, Sang-Don | 2007, 16(5) | pp.311~318 | number of Cited : 3
    Abstract PDF
    This study was conducted based on the 115 development projects of residential areas during2001-2006 to investigate the current status of park· green areas. Prior Environmental ReviewSystem (PERS) was categorized into regions, scales, and time of the projects, and regressionmodel was used for a statistical analysis. The ratios of greenness of Seoul and Gyunggi provincewere greater than those of other regions whereas the ratios of greeness of Cheonnam,Chungbuk, and Jeonbuk provinces showed smaller percentage of green areas. Secondly as thescales of development get bigger areas of greenness become larger indicating a large scaleresidential development projects are favorable for securing green areas. Thirdly the correlationbetween planned area and green areas, and that between planned population and the ratio ofgreenness are relatively low (P>0.05). This implies green areas are not a good indicator but aconcrete guideline for green areas. Fourthly the ratio of greenness of small scale project is notreached to 10% so that it is recommended to secure over one million m2 areas for developmentproject.

    Research on Subject Business of Prior Review Systemon the Influence of Disasters- Based on Quarrying Industry -

    나 영 , HwanGi Kim | 2007, 16(5) | pp.319~325 | number of Cited : 0
    Abstract PDF
    Recently, since the risk on natural disasters is increasing due to abnormal weather such as theglobal warming, a need for a system on prior review on the influence of disasters has emerged inorder to establish a solution by analyzing elements of disaster in advance. However, since theinherently destroying business namely the quarrying business is excluded from the range ofsubject business of Prior Review System on the influence of disasters, a correction for this isrequired. In order to actually explore how much risk it contains, actual outflow of soil and flood inthe quarrying block where quarrying is being currently carried out was examined and the requiredundercurrent facility capacity which is also used as a grit chamber was investigated. In addition, bycomparing the soil outflow of industrial complexes and golf courses which are current subjectbusinesses of Prior Review on the Influence of Disasters and that of rock mountains relative risklevel was examined. After investigation, it was found that the risk on occurrence of disasters wasincreased due to increase in outflow of soil and flood because of the change of land conditionduring and after development thus an adequate solution to decrease is required. In addition, aftercomparison with other business groups it was found that a significantly higher amount of soil isoutflown in case of rock mountains thus it was analyzed that a solution to decrease is required.Therefore, a correction is immediately required in order to include quarrying business in the subject business of Prior Review System on the Influence of Disasters.

    The Metallic Elements of PM10 and PM2.5 in Western Region ofBusan in the Springtime of 2005

    Jeon, Byung-Il | 2007, 16(5) | pp.327~340 | number of Cited : 1
    Abstract PDF
    The PM10 and PM 2.5aerosols were collected at Busan from March to May, 2005, and theconcentrations of some metallic elements were analysed to study their characteristics. The meanconcentration of PM10 was 66.5± 23.0 mg/m 3 with a range of 22.2 to 118.1 mg/m 3. The meanconcentration of PM2.5was 46.1± 17.2 mg/m 3 with a range of 9.7 to 83.3 mg/m 3. The ratio ofPM2.5/ PM10 was 0.69 at Busan. The distribution of metallic elements for PM10 and PM 2.5wereCd<Ni<Cr<Ti<Sr<....<Al<K<Fe<Si<Na and Cd<Cr<Ti<Ni....<K<Al<Si<Fe<Na, respectively.The mean mass concentrations of Asian dust and non Asian dust in PM10 were 94.9 mg/m 3 and63.7 mg/m 3, respectively. And The mean mass concentrations of Asian dust and non Asian dustin PM2.5were 56.9 mg/m 3 and 45.1 mg/m 3, respectively. The mean values of crustal enrichmentfactors for five elements (Cd, Cu, Pb, V and Zn) were all higher than 10, possibly suggesting theinfluence of anthropogenic sources. The soil contribution ratios for PM10 and PM 2.5were 20.5%and 19.4, respectively.

    An Analysis on the First Flush Phenomenon by Stormwater Runoff inEutrophic Lake Watershed

    CHO JAE HEON , 서형준 | 2007, 16(5) | pp.341~350 | number of Cited : 5
    Abstract PDF
    Lake Youngrang is a lagoon whose effluent flows into the East Sea. Because two resort townsand two golf courses are situated at the lake basin, many tourists visit this area. Stormwaterrunoff surveys were carried out for the eight storm events from 2004 to 2005 in the eutrophiclake watershed to give a basic data for the diffuse pollution control of the lake. Dimensionlessmass-volume curves indicating the distribution of pollutant mass vs. volume were used toanalyze the first flush phenomenon. The mass-volume curves were fitted with a power functionand polynomial equation curves. The regression analysis showed that the polynomial equationcurves were better than the power function in representing the tendency of the first flush, and second degree polynomial equation curves indicated the strength of the first flush effectively.

    Variation of PM10 Concentration in Seoul in Association withSynoptic Meteorological Conditions

    이정영 , Han , Jinseok , 공부주 and 3 other persons | 2007, 16(5) | pp.351~361 | number of Cited : 5
    Abstract PDF
    To evaluate dominant synoptic classes which affect on PM10 concentration in Seoul, 64synoptic classes are classified from four seasons, 850hPa geopotential wind and lower levelstability Index. In this study, we used air monitoring and meteorological data in Seoul for fiveyears from 2001 to 2005.The results indicate that the highest occurrence frequency of synoptic class is under a strongwesterly geopotential wind and stable lower atmosphere in spring. The highest PM10concentration of synoptic class is associated with a weak geopotential wind speed and highlower level stability. In that class, not only PM10 but SO2, NO2 and CO concentrations are alsohigher than other classes. The analysis of spacial distribution of PM10 concentration in each classare indicate that the influence of synoptic class are similar in the Metropolitan area in Korea. ButPM10 concentration in some areas in Kyoung-Gi are more higher than in Seoul. The relationshipbetween PM10 concentration and Meteorological indicator (relative humidity, temperature,surface wind speed) under same synoptic class is more correlative in Winter than other season.

    A Study on Evaluating Facilities within Urban Parks through a UserAwareness Survey

    성현찬 | 2007, 16(5) | pp.363~372 | number of Cited : 4
    Abstract PDF
    This study is to survey facilities installed at urban parks and identify park facilities desired byusers through a questionnaire survey of users who actually use the parks. Then, the outcomewill be compared and evaluated to install urban park facilities that reflect the desires of users inthe future.Findings showed that park facilities currently installed are mostly those easy to install andmanage among facilities suggested in relevant laws. Regardless of park types and sizes, similarfacilities were installed across parks. A questionnaire survey of users showed that they wantedfacilities to rest, sports facilities, waterscape facilities and facilities to accompany families. Theresult also showed that they wanted green area-style parks that have a lot of trees.Therefore, going forward, facilities reflecting such desires of users should be installed atparks as much as possible. When developing a park creation plan for each city, it would becritical to survey the opinions of residents in relevant areas in advance and reflect it to thecreation plan.
