With the development of transportation and communication and the advancement of industries, the importance of functional linkage between cities through networks has been emphasized as an urban growth strategy, which can be acting as a crucial mechanism for urban growth. Recently, it is analyzed that the Network between functionally differentiated cities induce growth by themselves complementary characteristics, presenting different perspective with the existing center theory as well. It is especially notable that urban growth mostly underlie the interrelationship between individual cities. Thus, it is needed to consider interaction between each cities in urban growth. This study applied the social network theory to analyze the centrality change in the Seoul metropolitan area and empirically found out the factors affecting the centrality change utilizing Interaction Index and industry characteristics. To this end, as of 2010 and 2019, 100 cities, counties, and districts within the metropolitan area and suburbs were set as the unit of analysis. The effect of interaction between regions and changes in location of industrial activities on urban centrality , and to provide data for base development according to regional interaction characteristics and regional strategic industry establishment in consideration of regional industrial structure and characteristics.

In order to better understand the role of litter layer on hydrological cycle in forest, we estimated the interception storage capacity of the litter layer at Gwangneung deciduous forest. We first made a thickness map of the litter layer at the study site based on field survey and then collected representative litter samples for the laboratory experiment. We constructed a measurement device consisting of sample tray, drain collector, tipping bucket, and a data logger. Using this device, we examined the relationship between the interception storage capacity (Ci) and the thickness (d) of the litter layer. For the range of d from 25 to 100 mm, there was a simple linear relationship between C(i) and d, which changed with the intensity of the simulated rain. The results were extrapolated to d smaller than 25 mm by considering that no interception occurs without litter layer. Overall, C(i) increased rapidly when d was low (< 25 mm) but the rate of increase decreased as d increased due to clumping. With an average thickness of 59 mm, the estimated C(i) at the site was 0.94 (±0.39) mm. Such an interception storage capacity of the litter layer is comparable to that of the forest canopy, suggesting that the litter layer can play an important role in the forest water cycle.
