The purpose of this research is, by analyzing major laws related to national territory and environmental planning, to prepare grounds to develop policies that should be realized as the national territory and environment linkage system has been established. Moreover, the importance of linkage between land and environment has been increased because environment should be included in the space planning process so that we actively deal with damage of environment. The land-environmental interlink system presents directions for linkage under the highest laws of the National Territory and Environmental Act. Nevertheless, in order for this concept to be practically applied to the processes for planning and development, the linkage between the sub-laws of national territory and environment should be included in the actual plans. Therefore, the purpose of this study is to derive characteristics and limitations of the major laws related to national territory and environment through respectively analyzing and identifying their detail provisions and spatial hierarchical characteristics.

Although antioxidant activities of Korean traditional fermented foods were reported by many researchers, study on antioxidant activity of microorganism originated from Korean traditional fermented foods was little. Therefore, we improved condition for antioxidant production by a bacterium isolated from home-made Chungkookjang. We selected a bacterial strain, which showed the highest antioxidative activity, from Chungkookjang and then named GJ. The selected GJ strain was identified as Bacillus methylotrophicus by alignment data of 16S rRNA gene nucleotide sequences. Improved medium compositions for DPPH radical scavenging activity were 0.25% sucrose, 1% peptone, 0.01% MgSO4ㆍ7H2O and initial pH 6.5, respectively. Optimal culture conditions were 30℃, 200 rpm and 4% inoculum volume, respectively. In improved conditions, DPPH radical scavenging activity of GJ reached to 91% in a short time. The strain GJ also possessed ACE inhibition and other antioxidative activities; ACE inhibition activity (49.4%), ABTS radical scavenging activity (99.8%), metal chelating activity (67.9%), SOD-like activity (36.5%) and reducing power (A700=5.982) were observed, respectively. Therefore, our results suggest that B. methylotrophicus Gj strain may be potential candidate for functional foods, cosmetic products for anti-aging and medicine for diseases caused by oxidative stress.
