Recently, recycling of the industrial by-products has been an important issue of the Yeosu bay, where large industrial complex is located. Major industrial by-products which are produced from Yeosu industrial complex area are phosphogypsum and flyash, which are about 82% and 10% of the 1.6 million tons industrial by-products. Moreover since the Yeosu industrial complex is located at seaside, phosphogypsum has been pointed as cause of serious environmental contaminant from the regional society. Therefore recycling study can't be delayed anymore. In this paper, artificial aggregate was manufactured by non-sintering process from industrial byproducts - e.g., phosphogypsum and slag - as a geotechnical drainage material. To show the feasibility of the artificial aggregate as a geotechnical drainage material, geotechnical experiments including particle size analysis, permeability test, and large scale direct shear test were carried out. Test results show that the permeability of the artificial aggregates range from $6.94{\times}10^{-1}cm/sec$ to $8.86{\times}10^{-1}cm/sec$, which is much larger value than those are required for the drainage material from the construction specification in Korea, and the friction angle of the artificial aggregate is as large as that of sand in water immersion conditions. From the test results, it was concluded that artificial aggregate made from industrial by-products can be used successfully as a geotechnical drainage material.

This study was conducted to select the location of the logistics center for environment-friendly agricultural products in the Gwangyang Bay Area. AHP(Analytic Hierarchy Process) technique was used to examine location selection factors and factor hierarchy was made through a questionnaire survey and an expert interview for objective and quantitative decision. The hierarchy process of location factors of logistics center for environment-friendly agricultural products in the Gwangyang Bay Area were categorized into five factors such as natural factors, economic factors, social factors, distribution efficiency, and land use plan. Then, those factors were sub-categorized into three factors each. As a result of pair-wise comparison analysis of five categories, the weight of economic factors was the highest, and easy cargo transportation, fitness to higher-order plan, climate, land price, and limitation regulations of sub-categorized factors appeared as comparative evaluation criteria. The priority of the final candidate was decided through this process. While the weight of the Yulchon II Industrial Complex was the highest in natural and economic factors were the highest, the weight of the Gwangyang Hwanggeum Industrial Complex was the highest in social factors, distribution efficiency, and land use plan. The result of the final analysis showed that the Gwangyang Hwanggeum Industrial Complex was the most optimal location candidate for the logistics center for environment-friendly agricultural products.

This primary purpose of this study is to suggest strategy a green-logistics strategy of Gwanyang bay area. The Green growth is the new growth concept based on the low carbon and environment-friendly industry. The new paradigm on the global economy growth requests a established logistics industry to be shifted into establishing the environment-friendly green logistics system. Some findings derided from this study are follows: Frist, in order to establish a environment-friendly green growth foundation, it is necessary to attract a green industry such as solar cell, wind force, hybrid car etc. Second, a green logistics system has to be established, including a green port strategy and reducing emission of carbon.

The Union of Kansai Governments of Japan is regarded as a bench marking for the successful cooperation, alliance, and cooperation of neighboring local governments. The Union of Kansai Governments was a realization several active plan of the Kansai Economic Federation. The purpose of this study is to examine the roles of the Kansai Economic Federation in the process for establishment of the Union of Kansai Governments, searching for theoretical implications for the inter-municipal cooperation of Gwangyand Bay in South Korea. In particular, this study review the activities and roles of the Kansai Economic Federation in relation with the establishment of a number of promotional organizations and governance systems. We played special attention to the three important factors carried out by the Kansai Economic Federation, that is, the contineous activities, the accumulated research results, and establishment of various promotion organizations and effective governance systems. We suggest, in conclusion, that these three factors would also have very important policy implications for the discussion of inter-municipal cooperation among three cities, Yeosu, Suncheon, and Gwangyang.

The objective of this study is to analyze the project performance and development process of the phase 1 project of GFEZ from 2004 to 2010. The phase 1 project from 2004 to 2010 is consist of eleven project zones. Among these zones, eight zones are currently underway and three zones have been completed. The performance of the phase 1 projects is no so much because it were stated later than planning with the difficulty of business developers selection. The major performances are development and supply of industrial & residential land, construction of road and railway, investment promotion of 102 companies, and creation of 20,971 new jobs. Most of the direct invested companies were located at Gwangyang and Yulchon Districts, and were mainly logistics and related service, iron and steel, machinery, shipbuilding, and fine chemicals. The main problems, however, are the limit of promotion of high-tech industries and large firms, low FDI reported rate, difficulty of superior business developers, delayed business progress of Hadong district. Therefore, efforts to solve these problems are required for the success of GFEZ.
