Risk management is an important element for successful management of overseas construction projects. This study reports a case study in which we proposed a risk management planning and procedure for plant construction which can be applied throughout the project life cycle. We analyzed the risk management practices of Korean construction companies by applying the concept of the PRINCE2 method developed in the UK, and proposed a risk management planning and procedure with organizational structure and working process. The suggested risk management planning and procedure was applied to an overseas plant construction project, and produced good results. It is believed that the procedure suggested here can also be aplied to other companies to enhance the competency in the global construction market.

As abnormal climate phenomena frequently happen due to the after-effect of the global warming, all nations suggest climate change response policies in many different fields to prevent global warming by reducing greenhouse gas. Especially, these days, the realization that the greenhouse gas from city buildings should be decreased is growing, and it is because that buildings are accounted for a quarter of national greenhouse gas emission and it is more than half the percentage of emissions within the city. Accordingly, Korean government sees the need to take an initiating role to fulfill low-carbon green policies and promotion strategies in the public sector, and wants to facilitate greenhouse gas reduction in the private sector as well. In this background, this study tries to examine the low-carbon planning element in public buildings and figure out the amount of carbon reduction and economic analysis centering Cheongju city as case study. Lastly, we propose some suggestion for low-carbon and greening of public buildings.

The purpose of this study is to investigate how regional resource-based industries affect regional economic space. To achieve this goal, a new framework has been proposed, which integrates traditional firm network models in economic geography with the concept of value chain. Firms' networks are elaborated and classified by firm activities along with global value chain. Firm-activities are composed of primary activities and supportive activities. Primary activities include, production, sales, and marketing. Support activities are conceptualized as networks of R&D and of firm support services. On the basis of this framework, fermented soy product industry, representative industry of regional resource-based industries in Korea, is analyzed. Finally, this study shows the dynamics of regional resource-based industry.

This paper presents a comparative study of wave height estimation method that was used for signal to noise ratio and shadowing ratio based on X-band marine radar. If the signal to noise ratio, and is widely used as a method for estimating an wave height, a new method is presented for shadowing ratio. In the case of radar images used in this study it is measuring the data from the coast of Ulsan Jujeon, compared with marine meteorological information from the Meteorological Agency measured a light beacon. We compared the measured data for about 34 days, the typhoon was measured, incluidng a period in the East Sea, and verify the results for various distribution of wave height. For estimate wave height using a shadowing ratio analysis, it does not require calibration and real-time advantages of this part, coming confirmed the possibility of the measurement, the cause detection error for radar image was caused due to determine.

The main factors that made Seoul's rapid population accommodation and urbanization possible in the mid-to-late 20th century were the ex-pansion of urban infrastructure, completion of the transportation system, and housing supply. The development of transportation and resi-dential development occurred simultaneously, and in particular, apartment complexes, a representative residential area in Seoul, were most influenced by Perry's neighborhood unit theory. The purpose of this study is to analyze the process of the physical environment of apartment complexes in the metropolitan area in response to development of transportation in the mid-to-late 20th century. The analysis sites are Jamsil Apartment Complex(1974), Dunchon Apartment Complex(1979), Mok-dong New Town(1983), Sanggye New Town(1985), Bundang New-town(1990) and Ilsan Newtown(1990), which were planned at the turning point of development of transportation and actively reflect the neigh-borhood unit theory. The analysis was conducted in three stages. Analyzing the status of transportation when the plan was established, deriv-ing the planning elements, and classifying the planning elements into walking, bus, car, and subway which is the representative transportation. The conclusions from the analysis are as follows. Firstly, completing the legal system and expanding the related infrastructure are essential. Secondly, in contrast to the increase in traffic volume, the pedestrian environment has been continuously improved. Thirdly, despite the emergence of new mode of transportation, there was a tendency to activate the linkage between transportation.

Adaptive mesh refinement scheme is incorporated with the Boundary Element Method (BEM) in order to get accurate solution with relatively fewer unknowns for the case of magnetostatic field analysis and A new and simple posteriori local error estimation method is presented. The local error is defined as integration over the element of the difference between solutions acquired us ing second order and first order interpolation function and is used as the criterion for mesh refinement at given grid. Case study for two dimensional problems with singular point reveals that meshes are concentrated on the neighbor of singular point and the error is decreased gradually and the solutions calculated on the domain are converged to the analytic solution as the number of unknowns increases. The adaptive mesh gives much better rate of convergence in global errors than the uniform mesh.

The Theory of Plastic Mechanism Control (TPMC) has been recently extended to the case of Eccentrically Braced Frames (EBFs) with inverted Y-scheme, i.e., EBFs with vertical links. In this paper a further validation of the design procedure, based on TPMC, is provided by means of Incremental Dynamic Analyses (IDA) pointing out the fulfilment of the design goal, i.e., the development of a pattern of yielding consistent with the collapse mechanism of global type where all the links are yielded and all the beams are yielded at their ends while all the columns and the diagonal braces remain in elastic range with the only exception of the base sections of first storey columns. In particular, a study case is designed according to both TPMC and Eurocode 8 provisions and the corresponding seismic performances are investigated by both push-over and IDA analyses. The results show the different performances obtained in terms of pattern of yielding, maximum interstorey drift, link plastic rotation demand and sharing of the seismic base shear between the moment-resisting part and the bracing part of the structural system. The seismic performance improvement obtained by means of TPMC, compared to Eurocode 8 provisions, is pointed out.
