GIS has been rapidly developed since 1995 when the Ministry of Construction and Transportation started the First National GIS Construction Project and built large scale topographic map at local governments level. From that time local governments have been built several application system such as road management system, waterworks management system, sewer management system, underground facilities management system, and urban planning information system, etc. However, the construction of GIS application system at different department level brings the problem of data sharing and overlapping database construction. To overcome this environment Enterprise GIS concepts has been introduced. In case of Seoul Metropolitan government Spatial Data Warehouse have been constructed. However, Seoul Metropolitan government still have the problem of inactive use of GIS system and adaption to the rapidly changing information environment. This study aims to present Strategic plan to uggrade Enterprise GIS concenpt from data centric to service centric architecture at local government level.

The Hebei Spirit oil pollution accident which occurred in Tae-an in 2007 has brought considerable impacts on the surrounding environment such as struggles among the regions and the residents in the damaged area as well as devastation of local economy and ocean environment. The majority of the impact was related with economic problem. Also, the main factor to cause the regional community conflict was found to be firstly economic problems and secondly the insufficiency of government's management system and policy measures for the community conflicts. Therefore, the government's policy to overcome oil accidents should focus on improvement of the economic support systems and conflict resolution. In this study, the support policies taken by government after the Hebei Spirit accident was examined and responsive policies which can be used by government in future accidents are suggested.

Since Jan. 2004, the Ministry of Construction and Transportation has partly introduced estimation system of historical cost data in order to reflect result cost of construction market to cost estimation for public construction. It is expected that the purpose of the introduction would be evaluated considering the long-term development of domestic construction industry. In article 3, paragraph 4 of the planning criteria of estimated cost of financial regulation related to government contract rule, the profit estimated by historical cost data indicates sales profit and it is calculated by multiplying the sum of direct cost, indirect cost and general overhead by rate of profit. Finally, it is said that rate of profit cannot exceeds 10%. However, there are a lot of constructions for electronic equipment in the electronic construction and the proportion of government furnished material is very high, not like engineering works or constructions. Therefore, as the proportion of material cost over direct cost is relatively lower if current rate of exceeds (10%) is applied, there would be a wide difference of cost in the items of profit under the estimation system of historical cost data. This paper was conducted to examine estimation methods of the items of profit under the estimation system of historical cost data and suggest reasonable applications.

Real-time traffic data are readily obtainable by traffic surveillance systems of intelligent transportation systems (ITS). Such data greatly support further applications in the field of traffic operations, planning, and safety. However, traffic data should be appropriately processed to fully exploit the benefits of data collection capability. Rather than developing individual data processing techniques, which is major concern of existing studies, this study proposes a novel methodology for evaluating data processing techniques in an integrated manner. Also, a tool for implementing the proposed methodology is developed. Users can extract useful and more reliable traffic data based upon their ultimate purpose of data usage by the evaluation tool developed in this study. Actual freeway traffic data are, as an example, fed into the evaluation tool, and results are discussed.

Soil-rock mixture (S-RM) is an inhomogeneous geomaterial that is widely encountered in nature. The mechanical and physical properties of S-RM are important factors contributing towards different deformation characteristics and unstable modes of the talus slope. In this paper, the equivalent substitution method was employed for the preparation of S-RM test samples, and large-scale triaxial laboratory tests were conducted to investigate their mechanical parameters by varying the water content and confining pressure. Additionally, a simplified geological model based on the finite element method was established to compare the stability of talus slopes with different strength parameters and in different excavation and support processes. The results showed that the S-RM samples exhibit slight strain softening and strain hardening under low and high water content, respectively. The water content of S-RM also had an effect on decreasing strength parameters, with the decrease in magnitude of the cohesive force and internal friction angle being mainly influenced by the low and high water content, respectively. The stability of talus slope decreased with a decrease in the cohesion force and internal friction angle, thereby creating a new shallow slip surface. Since the excavation of toe of the slope for road construction can easily cause a landslide, anti-slide piles can be used to effectively improve the slope stability, especially for shallow excavations. But the efficacy of anti-slide piles gradually decreases with increasing water content. This paper can act as a reference for the selection of strength parameters of S-RM and provide an analysis of the instability of the talus slope.
