This study analyzes important urban characteristics according to location of large-scaled professional sports facilities based on a binary logistic regression model and t-test. For the empirical analysis, this study uses 24 urban characteristics within social, economic, cultural, traffic, and spatial categories in 228 cities. The results show that economic condition can be the main decision factor for the differential feature of the location as well as social and traffic conditions. Concretely, more the number of young adults and middle-aged people who have considerable purchasing power, and available land are more the beneficial to the presence of the sports facilities. Recently local governments focus on location of the facilities due to their impacts on regional economics as well as residents' quality of life. In this point of vies, this study gives good understanding why it is a great option for location of the facilities.

Cyberspace is becoming increasingly important. Incidentally, there exist possibilities of the industrial secrets leaked, cyber attacks, privacy protection problems. In addition, there are growing concern of cyber war between nations. Thus potential hazards in cyberspace and the extent of damage are getting bigger. Therefore, a systematic understanding of cyber damage and damage scale is very important and damage estimation method should be developed to establish solid cyber protection system. In this study, current and potential damage types are understood and damage scales are surveyed based on the analysis of existing studies and try to develop a reasonable methods to estimate economic effects of cyber protection.

Creative industries are important due to the capability of enhancing urban competitiveness. This study is focused on unravelling the uneven growth and geographic distributions of creative industries. The main results are as follows. First, the primary city, Seoul, has too much eminence than the citysize rule suggests, and the creative-industry elasticity is very high compared to population and all industry. Second, Seoul is reinforcing the uneven growth with adjacent cities. Third, the local main cities have little power to enhance creative industries and the local small cities grow randomly. Fourth, each city should have more deliberation in accepting creative industries as an urban growth strategy.

This paper investigates the cost structure ot the Korea and Japan railroad industry with respect to density, scale and scope economies as well as productivity growth rate using a generalized trans)og multiproduct cost function model. The paper then assumes that the Korea and Japan railway companies pi·educe three outputs (incumbent railway passenger-kilometers. Shinkansen passenger-kilometers, ton-kilometers of freight) using four input factors (labor, fuel, maintenance, rolling stock and capital). The specified cost function includes foul other independent variables: track lengths to reflect network effects, two dummies to reflect nation and ownership effects, and time trend as a proxy for technical change. The simultaneous equation system consisting of a cost function and three input share equations is estimated with the Zellner's iterative seemingly unrelated regression. The unbalanced panel data used in the paper, a total of 154 observations. are collected from the annual records of the Korea National Railroad (KNR) for the yews $1977{\sim}2003$, Japan National Railways (JNR) for the years $1977{\sim}1984$. seven Japan Railways (JR's) for the years $1987{\sim}2003$. The findings show that the Korean and Japanese railways exhibit product-specific and overall economies of density but product-specific diseconomies of scale with respect to incumbent railway passenger-kilometers, Shinkansen-kilometers and ton-kilometers. However, the railways experience mild overall economies of scale which result from economies of scope associated with the joint production of incumbent railway/Shinkansen and feight, freight/incumbent railway and Shinkansen except Shinkansen/incumbent railway and freight. In addition, the economies of density and scale in the KNR, JR east, JR central, and JR west companies at the point of the years $1990{\sim}2003$ average is generally analogous to the above results at the point of sample average. There also appear to be economies of ssope associated with the joint Production of the incumbent railway and Shinkansen in JR central but diseconomies of scope in JR East and JR West. The findings also indicate that the productivity growth rate of the privately-owned JR's is larger than that of the government-owned KNR.
