This paper focuses on deriving policy alternatives in constructing uBio-City OSong. It is interested in combining construction plans of uBio-City OSong with Geoff Coyle’s ACTIFELD approaches. First, it is urgent to prepare additional financial sources. uBio-City OSong should be backed up by the appropriate business units, going beyond the consistent initiatives of the administrative units. Secondly, in order to set up an appropriate social infrastructure network, uBio-City OSong needs both long-run plan and road map which would facilitate various uBio services. Thirdly, in terms of institutional dimension, it would be better for uBio-City OSong to organize specialized task force teams in the nearest future, as the enlargement of human capital within its own administrative jurisdiction is essential in the present stage. Lastly, it should devise specific implementation tactics, all of which would contribute to upgrading its self-created brand value.

This study analyzes the efficiency of local public investment expenditures in Korea. Using Korean panel data for the period 1986-2005, the local product function was estimated. The estimation model was based on the annual data of mining and manufacturing value-added as the dependent variable. And the independent variables were the annual data of local capital, local labor and local public investment expenditures. Before the analysis began, a relatively new panel unit roots test and a panel cointegration test were performed. The estimation results showed that the coefficients of the local public investment expenditures of non-metropolitan areas have decreased in recent years. In this overall perspective, the local public investment expenditures of non-metropolitan areas in Korea are inefficient in recent years from the point of views of allocation and dynamic growth.

This article focuses on the challenge of developing North Korean Special Economic Zones (SEZs) successfully by utilizing and exploiting the competitive capabilities and the market forces of South Korean economy based on the theoretical approaches such as double diamond model and spatial fix perspective. In fact, among four North Korea’s SEZs. the Rajin-Sunbong SEZ has been regarded as a failure and the Sinuiju SEZ has been developing more slowly than was hoped. In contrast the Gaeseong SEZ and the Mt. Kumkang SEZ’s development have been making smooth progress. As matters stand now, this article suggests adopting a sequential approach for successfully establishing North Korean SEZs rather than adopting a simultaneous approach. South Korean competitive power will be stated with linking the Gaeseong SEZ and extended to Pyeongyang, the Sinuiju SEZ. The way to attract a foreign investment into SEZ is that the North Korean SEZs not only fully utilize its cheap labor forces but also South Korean’s attractive market demand. Competitiveness in labor forces appeals to multinationals seeking for production efficiency and the Seoul metropolitan area adjacent to the Gaeseong SEZ can be an attractive foreign investment climate to the multinationals seeking for potential market.

This study attempts to analyze the service area of greenspace on the subject of avaliable greenspace of wide areas in part of citizens’ accessibility and construct total greenspace system on the basis of this analysis. Assuming that the greenspace area per person is 6㎡ on the basis of the analysis result by the scenario 1, the total greenspace is estimated at 3,993.55㎢ and would be needed the 42.62㎢ more than 3,950.93㎢ at the present, and 10㎡ by the scenario 2, needed the 110.96㎢ more and 16㎡ by the scenario 3, needed the 225.02㎢ more. The method of measurement to service area of greenspace and calculation of amount of planning greenspace in this study are expected to make pleasant living environment because they can prescribe the location and quantity of new planning greenspace for several development works.

Korea has a tendency to solve the housing problem which is interconnected with residing stability of a citizen with the political matter than an economic principle. That policy is being repeated the regulation and the deregulation along the business cycle or the political power. However, it is shown the limit to the analysis that the response of market for the real estate and the flow of the market have correspondence to the political intention along the political regulation. The reason is following; it is difficult to make numerically the regulation of the policy for real estate or the level of deregulation. In this research, I estimate the level of the policy monthly investigating the policy for real estate since 1986 and use them as a policy variable adding the number of policy enforcement. ‘Model VAR’ is set with the policy variable and the rate of price fluctuations for the apartment market. Also, I analyzed the response of the market of each apartments by the policy for real estate with the impulse response function and the variance decomposition analysis. I conclude that the response of the market of apartment coincides with the intention of the policy for real estate and that it has different response with the local market or housing scale through the analysis.

The attraction of Cellular Automata(CA) urban growth models resides in their simplicity, flexibility, and transparency as a modelling framework, and they have been cited in much of the literature as a promising tool to model realistic urban growth. However, the lack of a rigorous calibration process for CA urban growth models is certainly one potential obstacle to their use. Researchers have found the solution for the calibration problems of CA urban growth model from the field of Artificial Intelligence(AI) equipped with heuristic search routines. AI technique of Genetic Algorithms(GA) can be one of the promising alternatives. A model for new city growth (the so-called NCGM: New City Growth Model) was developed using stochastically constrained CA. A GA was designed to calibrate the NCGM. Accuracy and consistency of the calibration results through the GA were sought using hypothetical data and real data and meanings for the calibrated values are sought. It was revealed that NCGM produced very reliable results based on the experiments using both hypothetical and real data. Underpinned by GA’s accurate and consistent calibration results CA urban growth models, such as NCGM, can be strengthened their position in simulating realistic urban growth.

This paper was to increase understanding on the u-City as a new industry in the upcoming ubiquitous era and drew evaluation criteria of u-City feasibility for the activation of industry provided by u-City. And by reviewing precedent papers and references regarding u-City, it drew proper evaluation criteria and evaluated u-City feasibility using AHP; economic feasibility, technological feasibility and policy feasibility were figured out as main criteria and resulted evaluation criteria for u-City feasibility. In this paper, we tested the inconsistency index for confidence degree of AHP evaluation and applied the three u-Citys - Paju·Woonjung, Gwanggyo, and Yungigun - in AHP model. We used against the case of being 0.2 or less in connection with the inconsistency index showing the confidence degree of the AHP analysis. According to the results, the total average of the inconsistency index showed up as 0.073. And the average of the inconsistency index showed up 0.0872 in the case of Paju·Woonjung, 0.0683 in the case of Gwanggyo, and 0.0636 in the case of Yungigun. As to this, we present not only the direction for the systematic u-City build-up but also the justifiability of u-City implementation. Moreover, there will be a value as the basic materials for reasonably propelling the u-City project.
