The high-resolution X-band SAR systems such as COSMO-SkyMED and TerraSAR-X have been launched recently. In addition KOMPSAT-5 will be launched in the early of 2012. In this study we developed the new method for persistent scatterer candidate (PSC) selection and network construction, which is more suitable for PSInSAR analysis using multi-temporal X-band SAR data. PSC selection consists in two main steps: first, selection of initial PSCs based on amplitude dispersion index, mean amplitude, mean coherence. second, selection of final PSCs based on temporal coherence directly estimated from network analysis of initial PSCs. To increase the stability of network the Multi- TIN and complex network for non-urban area were addressed as well. The proposed algorithm was applied to twenty-one TerraSAR-X SAR of New Orleans. As a result many PSs were successfully extracted even in non-urban area. This research can be used as the practical application of KOMPSAT-5 for surface displacement monitoring using X-band PSInSAR.

In Korea, it is significantly deficient in the study about tourism geology, which is a new branch of applied geology that would support the growth of ecotourism world-wide. The objectives of this study include (1) the promotion in geodiversity of tourism geology using the data for type and distribution patterns of geological and geomorphological landscape resources and (2) the redoubling of diversity in the environmental interpretation programs offered by the Korea National Parks Service (KNPS). Our field study discovered 212 geological and geomorphological landscape resources distributed in the area of Taean seashore national park. Coastal topography is the most discovered type followed by weathering topography. It is our belief that the aforementioned resources can be utilized as a tourism geological site in assisting the public to understand geological science and to draw their attention and interests after sorting and filtering it out through discussions with geologists and geomorphologists of a consortium. Furthermore, in order to promote the activation of developing user-oriented geotourism sites, it is recommended to keep monitoring on demographical characteristics of geotourists, behavioral characteristics of geotouconrists within the geotourism site and ducting analysis for developing geotourism program and events. And, the research support of geological engineering dealing with the estimation of weathering degree and the development of conservation techniques for the object of geotourism along with the research of environmental science aspects will improve the activation of tourism geology.

Domestic serpentinite is one of the important industrial minerals utilizing in the iron manufacturing company such as POSCO in Korea. Serpentinite is distributed in the Ulsan Fe deposit, Andong, Hongseong-Cheongyang, and Gapyeong areas. This study tries to interpret the relationship among the formation of carbonate rocks, iron mineralization, and serpentinite alteration throughout the study of field occurrence, mineralogy, and chemical compositions. Serpentine is formed by the break-down of olivine and pyroxene of parent peridotite. The serpentinization is inferred to be formed by the hydrothermal fluid derived from intruded Cretaceous granite and the addition of meteoric water. Variation of major oxides such as $SiO_2,\;Fe_2O_3$, and MgO in serpentinized rocks are controlled by the degree of serpentinization and Fe mineralization. Variation of $Al_2O_3$ and CaO contents of altered rocks is dependent on the amount of the residual minerals such as calcite and homblende, and on the degree of chloritization. The presence of carbonate rocks reported in the sedimentary origin or igneous origin (carbonatite) provided a geological environment to form skarn type Fe deposit regardless of its origin. The geological processes of Ulsan Fe deposits are inferred to be formed as the order of the formation of carbonate rocks ${\to}$ the intrusion of Cretaceous granite ${\to}$ serpentinization ${\to}$ Fe mineralization by the interprelation of field occurrence and mineralogical characteristics.

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.

The purpose of this study is to improve the accuracy of the urban runoff and drainage network analysis by using the observed water level in the drainage network. To do this, sensitivity analysis for major parameters of SWMM (Storm Water Management Model) was performed and parameters were calibrated. The sensitivity of the parameters was the order of the roughness of the conduit, the roughness of the impervious area, the width of the watershed, and the roughness of the pervious area. Six types of scenarios were set up according to the number and types of parameter considering four parameters with high sensitivity. These scenarios were applied to the Seocho-3/4/5, Yeoksam, and Nonhyun drainage basins, where the serious flood damage occurred due to the heavy rain on 21 July, 2013. Parameter optimization analysis based on PEST (Parameter ESTimation) model for each scenario was performed by comparing observed water level in the conduits. By analyzing the accuracy of each scenario, more improved simulation results could be obtained, that is, the maximum RMSE (Root Mean Square Error) could be reduced by 2.41cm and the maximum peak error by 13.7%. The results of this study will be helpful to analyze volume of the manhole surcharge and forecast the inundation area more accurately.

In Korea, it is reported that the study about tourism geology, which is a new branch af applied geology that would support the growth of ecotourism world-wide, is significantly deficient. The objectives of this study include (1) the promotion in geodiversity of tourism geology using the data for type and distribution patterns of geological and geomorphological landscapes resources, and (2) the redoubling of diversity in environmental interpretation programs offerend by National Parks Authority (NPA). According to this research results, 62 geological and geomorphological landscape resources in Naejangsan national park were observed. Weathering topography is the most discovered type followed by river, mountain and tectonic topography in decreasing order. It is thought that the above-mentioned data can be utilized to sort and filter by the discussion through consortium organized by geologist and geomorphologist. Furthermore, in order to promote the activation of developing user-oriented geotourism sites, the monitoring on demographical characteristics of geotourists, behaviora characteristics of geotourists within geotourism site, and the analysis for developing geotourism program and events should be accompanied. And, the support of geological engineering dealing the estimation of weathering degree and development of conservation techniques for the object of geotourism will improve the activation of tourism geology.

This paper is to consider the development process of conflict between Daegu and Gumi which has been arisen from Daegu city's plan of relocation of water intake plant. It first argues that water is a major common and public resource which is circulated through the social process as well as the natural one, and hence that conflicts within or between regions due to its allocation should be resolved or managed by construction of collaborative governance in which all stake-holders participate. In particular, it is pointed out that collaborative governance would be not only oriented to a normative goal, but also be mobilized as a strategic means. On the basis of this conceptual consideration, this paper explores the development process of conflict caused by Daegu city's plan of relocation of water intake plant, and analyze the starting conditions and deliberation process of the public-private committee which has been constituted through a consensus between Daegu and Gumi city government. It concludes that the current interruption of the committee has happened, because it has been mobilized politically as a strategic means for regional hegemony, not as a normative one to resolve the conflict.

High-resolution multichannel seismic data were collected in the coastal area near the Gori nuclear power plant to investigate Quaternary fault pattern and timing. A 12 channel streamer, a sparker, and a portable recorder were used for data acquisition. Because the group interval of the streamer was 6.25 m and the sparker can generate acoustic waves with the frequency content of up to 500 Hz, the data show a significant improvement both in horizontal and vertical resolution. The area surveyed is covered with 30-40 m thick Holocene sediments that constitute the mud belt along the southeastern coast of Korea. The survey area is characterized by the well discriminated Pleistocene and Holocene boundary and shallow gas-charged zones. A number of Quaternary faults were found in the sediment column, that are nearly vertical and extend north-south. The Quaternary faults, arranged at a spacing of a few hundred meters, suggest that they were formed in response to compression, although some of them reveal extensional characteristics. Locally, faults disrupt Incised-channel fills that are interpreted to have formed in the early stage of transgression after the beginning of the Holocene. Seismic sections suggest that shallow gas in the mud belt sediments made its way upward through the fractured fault planes. The tectonism responsible for the opening of the East Sea has not persisted since the late Miocene, but vigorous Quaternary faulting activity in the vicinity of the southeastern Korean Peninsula indicates that tectonic stability has yet to be achieved in this region underlain by the hotter than normal mantle.

The coastal area forms various sedimentary layers according to the environmental conditions such as the topography and geological features of the upper region of the river, ocean currents, and river mouth. Therefore, identifying the characteristics of the marine clay deposited in the coastal area plays a key role in the investigation of the formation of soft ground. In general, alluvial grounds are formed by a variety of factors such as changes in topography and natural environment, they have very diverse qualities depending on the deposited region or sedimentation conditions. The most important thing for the construction of social infrastructures in soft ground areas is economical and efficient treatment of soft ground. In this study, the author collected data from diverse laboratory and field tests on five areas in western and southern offshore with relatively high reliability, and then statistically analyzed them, thereby presenting standard constants for construction design. Correlation between design parameters such as over consolidation ratio, preconsolidation pressure was analyzed using linear and non-linear regression analyses. Also, proposed distribution characteristics of design parameters in consideration of each region's uncertainty through statistical analyses such as normality verification, outlier removal.
