Changes in the soil physical property and the topographic condition derived fromagricultural activities like as farming activities, land clearance and cutting down resulted inenvironmental and economic problems including the outflow of nutrient from farms and thewater pollution. Several theories on the soil conservation have been developed and reviewed toprotect soil erosion in the regions having a high risk of erosion. This study was done using thesteepness made by Desmet and Govers (1996), and Nearing (1997) to evaluate the potential ofthe soil erodibility. Therefore, several results were obtained as follows.First, factors affecting the soil erosion based on the USLE could be extracted to examine theerosion potential in farms. Soil erodibility (K), slope length (L), and slope steepness (S) wereused as main factors in the USLE in consideration of the soil, not by the land use or land cover.Corresponding Author: Jang, Gab-Sue, Dept. of Environmental and Ecological Research, Chungnam Development Institute, 138-42 SangDae-Dong, YuSeong-Gu, DaeJeon 305-313, Korea Tel: 82-42-820-1182 Fax: 82-42-820-1129 E-mail: janggs@cdi.re.kr

The Korean government adopted the integrated stream water management policy recentlywith growing perception that natural disasters and pollution in Korea have been due not onlyto such human factors as urbanization and industrialization, but also to the policy offunctionally separated management of irrigation, flood control and ecological management.Contrary to its good intention, research result shows that it is not realistic to expect that thisnew integrated policy in Korea will work well.In order to be an effective policy and program evaluation, this paper suggests that evaluationindicator on related programs and projects should be made through bottom-up process. Forexample, environmental benefit should be taken into account rather than just economic benefit,and cultural and social characteristics in the project region should be also considered seriously.

The factor of air pollution in a large industrial city is not only manufactories but also,activities related to trucks. Sihwa National Industrial Complex is located in Siheung City; due tothe industries, more diverse activities related to trucks occur in Siheung City than other cities. Inparticular, the new residential area in Siheung City is close to the industrial complex; so, theother areas.The aim of this study is to analyze influence of the air pollution by a truck in Siheung City.ISCST3 Model and Arc View program were used for this study and Siheung City was dividedinto 1,000 meter by 1,000 meter grid to analyze. Furthermore, this study suggested tworeduction controls of air pollution in Siheung City, and analyzed the results from thesereduction managements.The results of the present condition showed that residences located in north of SihwaIndustrial Complex are influenced by air pollution material. Furthermore, air pollution bytrucks has affected on the residents which is near the road in Siheung City.
