A large suite of official statistical data sets has been compiled for geographical units under the national directives, and it is the quantitative regional analysis procedures that could add values to them. This paper reports our attempts at prototyping a statistical GIS which is capable of serving over the Web a variety of regional analysis routines as well as value-added statistics and maps. A pilot database of some major statistical data was ingested for the city of Seoul. The baseline subset of regional analysis methods of practical usage was selected and accommodated into the business logic of the target system, which ranges from descriptive statistics, regional structure/inequality measures, spatial ANOVA, spatial (auto) correlation to regression and residual analysis. The leading-edge information technologies including the application server were adopted in the system design and implementation so that the database, analysis modules and analytic mapping components may cooperate seamlessly behind the Web front-end. The prototyped system supports tables, maps, and files of downloadable format for input and output of the analyses. One of the most salient features of out proposed system is that both the database and analysis modules are extensible via the bi-directional interface for end users; The system provides users with operators and parsers for algebraic formulae such that the stored statistical variables may be transformed and combined into the newly-derived set of variables. This functionality eventually leads to on-the-fly fabrication of user-defined regional analysis algorithms. The stored dataset may also be temporarily augmented by user-uploaded dataset; The extension of this form, in essence, results in a virtual database which awaits for users commands as usual. An initial evaluation of the proposed system confirms that the issues involving the usage and dissemination of information can be addressed with success.

This study is conducted to find out problems in the implementation system of regional informatization policies in Korea and solutions to enhance the effectiveness in policy execution. The study uses research methodologies such as participant observation, interview and AHP for experts and employees of public organizations for regional informatization policies. Many implications were found in the analysis, including that policy relations, structure of the policy implementation system, and environment and contents of regional informatization policiesin Korea have to be innovated and re-organized. Especially, this paper emphasizes the horizontal and cooperative relationship between the central and local governments and redesigning of the legal system on the regional informatization. This paper also shows expectations on reshaping of the regional informatization policies with the paradigm shift of the government power toward decentralization. This paper also finds diverse views on the problems and solutions for the regional informatization policy implementation system based on different characteristics and interests of policy participants. This paper finds the possibility of applying the policy network model to regional informatization policy implementation, which can be supported by Rhodes & Marsh(1992)'s theory. Therefore, this paper shows the change of regional informatization policies can be expected through application of the policy network. Although the paper draws many academic and policy implications, they are limited to the implementation system of regional informatization policies only.

The weight-to-power ratio of the standard truck for the climbing lane design is known to be 200lb/hp. The value was known to be assumed based on constant trucks' capability and regional distributions in stead of widely varied distributions region by region. Additionally, this value was assumed after investigating registered vehicles' statistics instead of investigating real portions of truck volumes. Therefore, it may be said that the value of the current standard truck does not reflect regional or industrial diversity and proportions of truck volumes. To resolve these issues, the present paper studies diversified standard trucks which consider regionally or industrially diversified and observed-volume based weigh-to-power ratios. For this purpose, individual trucks' weigh-to-power ratios obtained at toll-gates of national expressways were used. For regionally based study, the whole nation are divided into 8 regions, then each region is characterized by a unit of a weigh-to-power ratio. The applicability of each value is provided. Results show that the single value for the nationwide standard truck may be 208 lb/hp, 8 lb/hp higher than the current value of 200 lb/hp. Results also show that regional values ranged widely from 170 lb/hp to 230 lb, 30 lb/hp higher/lower than the current value. Conclusively, regional diversity of trucks' weigh-to-power ratios was identified then three types of standardized weigh-to-power ratios which may represent regional characteristics were suggested. As the diversified standard truck are applied to the design standard, two benefits are expected such as decrease of rear-end accident rates or decrease of climb lane construction costs.

To examine the problem structure of balanced regional development policy and identify the causes of the gap between the capital and non-capital areas, this study examined the causal structure in terms of the concentration and distribution of functions in the metropolitan area and non-capital area and explored the policy leverage. As a research method, the causal map was drawn using System Dynamics techniques and policy leverage was derived through an exploration of the feedback structure. In particular, the causes of the problems in balanced regional development policies were approached by system accidents rather than by single-circuit accidents, and causality analysis was performed among the variables constituting balanced regional development policies based on system accidents. In particular, it singled out 31 variables, developed 13 feedback loops, and confirmed four major policy leverages, including relocation of the capital function, local decentralization policies, consistent development, and investment practices centered on the Non­Capital Area. Subsequently, a follow-up study by computer simulation is needed by modeling the structure of the system to identify the ripple effect of the policies of the Capital Area on the Non­Capital Area.

According to the returns of Housing and business cycle over the period 1992 to 2007, it is a measure of the total volatility faced by investors in Housing properties. First, it isn't a distinct difference from business cycle contrary to U.S. Second, the rise of purchase price in total apartments moves up the consumer price index. According to the cross-sectional dispersion of returns and growth in net operating income (NOI) of apartments, industrial, retail and office properties using panel data for U.S. metropolitan areas over the period 1986 to 2002, it is a measure of the total volatility faced by investors in commercial real estate. To the extent that most of that volatility is difficult to diversify, cross-sectional dispersion may be an appropriate measure of risk.

This article is based on the findings of problems and limits in implementing integrated coastal management strategy in Shihwa Lake area to develop management framework, mechanisms and processes that insure the participation of various stakeholders in making decisions for sustainable development of reclaimed land. The project performance of the Shihwa Comprehensive Management Plan for Water Quality and Environment Restoration formulated in 2001 was evaluated and reviewed to give some valuable guidance for reducing the wide gap between integrated planning and implementation. Managing inter-sectoral conflicts among future land uses in Shihwa reclaimed area is one of the most important issues to make progress in integrated coastal management. There is a urgent need of developing scientific decision-supporting tools for evaluating the alternative scenarios as well as capacity building programs for local stakeholders.

This work aims to propose a vulnerability assessment methodology of ecosystem at present time, and an to suggest an adaptation strategy of ecosystem in the future for local government, in the fields of plant, animal and conservation area, which would occurred due to climate change. Vulnerability assessment in ecosystem includes first, tree growth and distribution part, mainly for conifers, secondly, insect part for pest and bee, and thirdly conservation area management part, especially at the national parks. To evaluate the degree of vulnerability of each substitute variables, such as exposure of climatic element, sensitivity, and adaptation ability, are respectively selected. Vulnerabilities of conifer growth and distribution, pest and bee, and national park management seem to be strongly influenced by the exposure of climatic element than other factors, such as sensitivity and adaptation ability. With time regional gaps of ecosystem vulnerability are expected to be greater in both conifers growth and distribution, and national park management, but reduced in pest and bee in 2100 in comparison with present time.

The purpose of this study is to research on the distribution and correlation of population, industrial employees and highest land value of Seoul. The followings are result of the study. First, the population of Seoul City in 2012 decreased by 0.3%, compared with that in 1996. While the population of Gangbuk decreased, that of Gangnam increased. Second, the number of industrial employees showed larger gap than population, and it showed larger regional gap on producer service. Third, Jung-gu in Gangbuk had the highest land value among commercial areas of Seoul, but there was no significant gap between Gangbuk(Jung-gu and Jongro-gu) and Gangnam(Seocho-gu and Gangnam-gu). Fourth, in the average of the highest land value of residential area of Seoul City, Gangnam was more expensive, because of facilities and living conditions of Gangbuk and Gangnam is big difference. Fifth, the regional gap of the highest land value and the lowest land value of Seoul City is commercial areas larger than residential area. Finally, there was no correlation between the distribution of population and land value, between the increase of population and that of land value, but there was positive correlation between the distribution of industrial employees and the highest land value of commercial area and residential area of Seoul City.
