The direction of this study lies in exploring a schematic proposal for a historical walk over an area called 'West Village' located inside the old city wall of Seoul. The case study area is comparable to the historic 'North Village,' including historical assets such as the Kyunghi Royal Palace and Sajik-dan. Moreover, it has spectacular scenic spots surrounding Mt. Inwang and Baegundong Stream, although this has now been paved over for use as a road. This village maintained its fame as a hub of art through the early 20th century. The comprehensive approach of this study ranges from the historical and cultural to the ecological and visual. The results of this study can be summarized as follows. A themed walk would commemorate the great leader of national independence, Baegbeom Kim Ku, as well as the famous Korean style realistic landscape painting school under the leadership of Kyumjae Jeong Seon, a great artist of the Josun Dynasty. In addition, a scenic streamside walk would accentuate the surrounding panoramic vistas which were drawn by Kyumjae, while at the same time allowing the ecological system of Baegundong Stream to be uncovered and restored.

Recently, the usage of elastic paving using EPDM Chip instead of pedestrian sidewalk blocks or permeable concrete used mostly for pedestrian walk, trails and in parks has been increassed as it can absorb impact during walking and produce wide range of colors and designs. However, the properties of EPDM Chip including elasticity and durability are decreased when exposed to ultraviolet ray and scenic paving functions through various colors are lowered due to the yellowing phenomenon. In this study, ultraviolet ray accelerated weathering test has been conducted to analyze the color changes in EPDM Chip and polyurethane resin, which are the main ingredients of elastic paving, when exposed to ultraviolet ray. The color differences are quantitatively analyzed through the color value coordination of the colored space by using the color difference scheme. The experimental results show that the color changes in BL polyurethane resin which is used most frequently at present was larger than that of EPDM Chip. Moreover, the total color difference, ${\Delta}E$, of BC polyurethane resin are 3.162 on the $14^{th}$ day of commencement of acceleration, which is 6 times greater color change resistance against ultraviolet ray than that of BL polyurethane resin with total color difference of 20.639. Therefore, the usage of BC polyurethane resin, which is manufactured to have chain-type molecular structure by using the isocyanate as the HMDI at the time of producing polymer, as binder in elastic paving with EPDM Chip is found to be a highly efficient method of restraining the color changes due to the ultraviolet ray.
