  • Growth in population and urbanization has progressively increased the loading of pollutants from nonpoint sources as well as point sources. Especially in case of road regions such as city trunk road, national road and highway are rainfall and pollutants runoff intensive landuses since they are impervious and emit a lot of pollutants from vehicle activity. This research was conducted to investigate the nonpoint sources concentration and quantifying stormwater pollutants which are contained in rainfall runoff water. Three different monitoring sites in Jinju and Changwon city were equipped with an automatic rainfall gauge and flow meter for measuring rainfall and the volume of rainfall runoff. In the case of average EMC value, city trunk road was shown the highest value in target water quality items like as BOD, COD, SS, TN and TP. Or the amount of runoff loads by water quality items showed the highest value in city trunk road. And runoff load in city trunk road was 43.8 times high value compared to highway by value of city trunk road $356.7 mg/m^2$, highway $8.150 mg/m^2$, national road $19.99 mg/m^2$ in the case of BOD.

  • The purpose of this study is to investigate the environmental value of green space in Seoul. Longitudinal relationships between land use patterns and $SO_2/NO_2$ have been analysed. Then the environmental and economic value of green space were examined. In this study, the following results have been found : Firstly, it was found that the amount of $SO_2$ showed the negative relations with green space but had the positive relationships with the built-up area. Which in turn can be interpreted as securing the green space could improve the $SO_2$ purification capacity. Secondly, Seoul Metropolitan green belt zones absorbed 69,728 tones of $CO_2$, 654 tones of $SO_2$ and produced 51,205 tones of O2 at the year of 1997 standpoint. This results implicate that the Seoul Metropolitan green belt zones resolve 0.2% of $CO_2$ and 2.9% of $SO_2$ production in total. Finally, the occurrence of an additional costs of 6,800 Korean Won per household was expected due to the air conditioning cost increases as the green belt areas decrease. Therefore, it is recommended to establish the alternative plans for the protection and creation of the green space in the urban areas, since those urban green space have the significant meaning as their provision of habitats for the wildlife as well as their contribution to the reduction of energy consumption.

  • This study aims to propose an assessment model on environmental economics which will provide useful information in making a decision for the implementation of pro-environmental and economical construction projects. To meet the objective, this study suggests a procedure to estimate environmental cost of construction projects. The model combines environmental load assessment and environmental value assessment. The environmental cost of pollutant generated from the construction project was estimated utilizing the Contingent Valuation Method (CVM) which is a value assessment method borrowed from economic science. The devised model is expected to provide a useful methodology that will scientifically support the planning and management of sustainable construction not only in the environmental aspect but also in the economical aspect.

  • Total Economic Value (TEV) provides a framework to estimate the economic value of water resources including groundwater with multiple applications to natural resource economics and environmental economics. Crucial to the application of economic analysis to natural resources are techniques to value the resources as an economic value that is expressed in monetary terms. On the other hand, the aim of TEV estimation is to determine the economic value of water resources including 'use' with production and recreation and 'non-use' such as existence values. TEV is used to assess the economic value of water resources for the multiple goods, and environmental 'services' that are provided by a water resource and also used to assess options for water use, for example balancing production values provided by water resource use against the cost of resource degradation by that use. The value of TEV can be assessed over time where pollution or unsustainable use may reduce the economic value of an environmental asset. Therefore, values are used to assess options of resource use, sometimes leading to policies on resource conservation or allocation. In conclusion, the application of TEV would be well adjusted over Jeju Island where groundwater resources account for more than 98% water resources and the budget of water demand/supply shows disparity over the Island.

  • The purpose of this study was to examine how the life styles of Korean people are influenced by the value systems of different generations. We analyzed the survey data of the 869 Korean participants aged from 20 to 69. The following results were obtained. First, differences exist among generations in various values such as collectivism, authoritarianism, environmental control, individualism , universalism, egalitarianism, and environmental accommodation. Especially, the older generation shows high scores in collectivism, authoritarianism and environmental accommodation, among traditional values. On the other hand, younger generation scored a higher level in individualism and egalitarianism. Second, there is a generation gap in the life style, as shown in family activities, household work, consumption activities, and leisure activities. In family activities, leisure activities and consumption activities, the younger generations gained higher scores than the older generations. Third, Korean people's value systems affect their life styles. Also, it was found that the interaction between the genera(ion and the value systems affects the life styles of Korean people.

  • National parks are designated for the purpose of maintenance, conservation and utilization of different habitats. Therefore, it is necessary to select habitats of a high value as a protected area in order to balance conservation and development. However, the existing national park boundary adjustment and new designation criteria only focused on the endangered species and protected area, without proper evaluation of the habitat value of actual species. Therefore, this study aims to quantitatively evaluate habitat function in terms of biodiversity and habitat value, so that it can be referred to for the designation and boundary adjustment of national parks. We assessed species diversity and habitat values for each of the habitat types, for mammals only, as they are able to choose preferred habitats. In order to evaluate biodiversity, we used Maxent to derive species richness map and used InVEST's Habitat quality model to evaluate habitat value. As a result of evaluation, species richness was high in the national park boundary area. Also, even if the same edge is adjacent to the development area depending on the land cover, the species richness is low. Compared with Wolaksan and Sobaeksan National Park, the species richness and habitat value of the northern area, which is connected with other forests, were higher than those of the southern area where roads were developed. Therefore, it is expected that the use of the result of this study for the national park boundary adjustment and management will enhance the function of the national park as a habitat.

  • In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.
