Uiwang ICD, which is the only inland container depot in the capital area, is equipped with modern facilities, and loading and unloading equipment, and can handle 1,000,000 TEU annually.It has many advantages such as advantageous conditions of location, the role of foothold for distribution transportation in the capital area, so it plays an important role of vitalizing the railroad transport. However, Uiwang ICD has reached the limit in the vitalization of railroad transport of containerized cargo due to the current problems in facilities and operations. This research analyzed the Uiwang ICD's problems by dividing them into facilities problems and operational problems, and presented short-term and medium and long-term improvement measures with the year 2023 when the private use permission expires as the basic year. However, the vitalization of railroad transport of Uiwang ICD can be attained only when it has support and cooperation from the government, Uiwang-si, Korea Rail Network Authority, and other related organizations together with efforts of Korea Railroad Corporation, and occupant companies. Such improvement measures for Uiwang ICD are expected to contribute to establishing combined transport system and forming efficient railroad distribution infrastructures and vitalizing railroad distribution, and also contribute to the government's low-carbon green growth policy by building environment-friendly transport system.

This paper proposes the bus-tie application scheme of 154 kV SFCL (superconducting fault current limiter) in Korean power system. The reduced amount of fault current by SFCL is different by where the SFCL is installed. Therefore the inflow ratio of fault current (IRFC) is suggested to consider the effect of an SFCL's location. The proposed scheme was applied to the Korean Power System of 2010, and fault currents were calculated and analyzed with this coefficient. Simulations show that the location with high IRFC is adequate to install SFCL but more consideration of other things is required to determine the location and capacity of SFCL.

To understand and compare tracer transport in fractured and porous media. multiple tracer tests were conducted in Wonju and Uiwang sites. The target media were fractured in Wonju site and porous in Uiwang site. It was known that groundwater flow for the two hydrogeologic systems could be represented using a EPM approach. However, the tracer transport in the two aquifer systems was greatly different. In this study, we analyzed the different tracer transport behavior in the two systems, from which our understanding of the tracer dispersion was greatly enhanced. we used bromide and chloride as tracers.

The purpose of this study nun to obtain basic information about the state of the physically disabled due to neurological impairments in order to provide precise data for planning and evaluating the Community Based Rehabilitation in Uiwang. The results were 1) the total number of registered disabled adults with cerebral vascular accident in this city consulted was 80 and the Prevalence rate was 1.0575 of total disabled Persons, 2) under 100 of the score of activity of daily living(ADL) with the subjects was 41.245 as Functional Independence Measure(FIM) and 3) ender 20 of the score of motor ability with the subjects was $45.1\%$ as Motor Assessment Scale(MAS). This results show that rehabilitation program for community based rehabilitation(CBR) should set up for each level of motor ability and ADL.

The Late Pleistocene pollen record from the Poil-dong, Uiwang, Kyunggi-do, reveals that mixed coniferous and deciduous broadleaved forests were spread along with herb and fern understory. Palynofloral changes reflect climate fluctuations. From ca. 43,100 to 41,900 cal. yr BP, a mixed coniferous and deciduous broadleaved forest combined with open grassland occupied the study area, which indicates cooler condition than today. During the period of ca. 41,900-41,200 cal. yr BP, along with fern understory a decrease in subalpine conifers and an increase in temperate deciduous broadleaved trees suggest a climatic amelioration. A climatic deterioration, as evidenced by an increase in subalpine conifers and a decrease in the density of vegetation cover, occurred from ca. 41,200 to 39,700 cal. yr BP.

In the United States (U.S.), the monitored natural attenuation (MNA) approach has been used as an alternative remedial option for organic and inorganic compounds retained in soil and dissolved in groundwater. The U.S. Environmental Protection Agency (EPA) defines the MNA as“in-situ naturally-occurring processes include biodegradation, diffusion, dilution, sorption, volatilization, and/or chemical and biochemical stabilization of contaminants and reduce contaminant toxicity, mobility or volume to the levels that are protective of human health and the environment”. The Department of Soil Environment. National Institute Environmental Research (NIER) is in the process for demonstrating the MNA approach as a potential remedial option for the BTEX contaminated site in Uiwang City. The project is charactering the research site in terms of the nature and extend of contamination, biological degradation rate, and geochemical and hydrological properties. The microbial-degradation rate and effectiveness of nutrient and redox supplements will be determined through laboratory batch and column tests. The geochemical process will be monitored for determining the concentration changes of chemical species involved in the electron transfer processes that include methanogenesis, sulfate and iron reduction, denitrification, and aerobic respiration. Through field works, critical soil and hydrogeologic parameters will be acquired to simulate the effects of dispersion, advection, sorption, and biodegradation on the fate and transport of the dissolved-phase BTEX plume using Bioplume III model. The objectives of this multi-years research project are (1) to evaluate the MNA approach using the BTEX contaminated site in Uiwang City, (2) to establish a standard protocol for future application of the approach, (3) to investigate applicability of the passive approach as a secondary treatment remedy after active treatments. In this presentation, the overall picture and philosophy behind the MNA approach will be reviewed. Detailed discussions of the site characterization/monitoring plans and risk-based decision-making processes for the demonstration site will be included.

This paper considers the problem of scheduling loading and unloading operations of a crane in a railway terminal motivated from rail-road container transshipment operations at Uiwang Inland Container Depot (ICD). Unlike previous studies only considering the total handling time of containers, this paper considers a bi-criteria objective of minimizing the weighted sum of the total handling time and tenant service time. The tenant service time is an important criterion in terms of terminal tenants who are private logistics companies in charge of moving containers from/to the terminal using their trucks. In the rail-road container shipment yard, the tenant service time of a tenant can be defined by a time difference between beginning and finishing loading and unloading operations of a crane. Thus, finding a set of sequences and time of the crane operations becomes a crucial decision issue in the problem. The problem is formulated as a nonlinear program which is improved by linearizing a nonlinear constraint in the model. This paper develops a genetic algorithm to solve the problem and performs a case study on the Uiwang ICD terminal. Computational experiment results show that the genetic algorithm shows better performance than commercial optimization solvers. Operational implications in terms of tenants are drawn through sensitivity analyses.
