Presence of old newspapers printed with waterbased flexographic inks leads to a significant loss of brightness of the deinked pulp by flotation process. It has been shown that neutral or acidic flotation deinking has many advantages in recycling of flexo printed newsprints. A comparative experimental study was performed to evaluate the deinking efficiency of three alcohol type deinking agents in flotation deinking of flexo printed newspapers. Zeta potential of neutral deinked pulp was less negative than alkaline deinked pulp. Also neutral deinking was advantages in reducing turbidity, COD, and cationic de-mands of deinking process water.

The objective of this paper is to analyze the competitiveness of the Cargo Management improvement of FTZ(Free Trade Zone) in East Asia and to suggest several measures to improve it. To the end, various comparisons are made between the FTZ of Incehon and those in Hongkong, Taiwan, Shanghai. Competitive advantages of Incheon's FTZ over others lie in its better contiguity, frequency, quality service, and convenient connections associated with the airport. To be viable, however, the Incheon's FTZ needs to have strong supports from the central government such as more SOC investment, early introduction of RFID/UBIQUITOUS, improvement of customs process and logistics system, and competitive incentives to bring in more international channel hubs to this area. With these implemented promptly as suggested, the Incheon's FTZ will draw its competitive advantages over those in Taiwan and Shanghai and will play an vital role to bring in more MNEs to Korea.

Northeast Asia's burgeoning mage- cities have an extraordinarily economic vitality. While national statistics disguies how economic activity is concentrated, much of the region's robust growth of recent decades has centered around large cities, such as Tokyo, Seoul, Beijing, Shaghia, Hongkong. These cities are also at the heart of the Northeast Asia's emerging reional economy. This paper aims to compare the advantages and disad- vantages of these selected Northeast Asia cities in various categories of urban competitiveness and cooperation. Above all, the paper compares the individual cities with one another, and analyzes relations and linkages among them. Then, strengths that can be reinforced and weakness that can be overcome are identified for each city. Finally, an urban development strategy for Seoul in the context development strategy for Seoul in the context of Northeast Asian cities is provided : I) Seoul should strive to be an effective regional capital of Northeast Asia ; ii) Seoul should be a focal point for the intermingling of Chinese, Japanese and Western cultures.

In this study, the applicability of SOM(Self Organizing Map) algorithm to partial discharge pattern recognition have been investigated. For the purpose, using acquired data from the artificial defects in GIS, SOM algorithm which has some advantages such as data accumulation ability and the degradation trend trace ability was compared with conventionally used BP(Back Propagation) algorithm. As a result, basically BP algorithm was found out to be better than SOM algorithm. Therefore, it is needed to apply SOM algorithm in combination with BP algorithm in order to improve on-site applicability using the advantages of SOM. Also, for the pattern recognition by use of PRPDA(Phase Resolved Partial Discharge Analysis) it is required the normalization of the PRPDA graph. However, in case of the normalization both BP and SOM algorithm have shown worse results, so that it is required further study to solve the problem.

Brebbia's model has been analyzed to develop the appropriate waterworks management system in Korea, and compared with the conventional models such as EPANET, WaterCad, and InfoWorks. The hydraulic theory of the models was analyzed. Each model's numerical techniques, required parameters, input data and operational methodologies, restrictions, practical applicability and other aspects were investigated. In order to check the validity of Brebbia model, the comparative analysis with EPANET, WaterCAD, and InfoWorks models was performed for linear and nonlinear cases. To find out advantages and disadvantages of each model, the modeling was performed for a simple network and for more complicated A city waterworks system, and the three models applicability was examined. Finally, optimal modeling technique and a model suitable for the use in Korea was suggested, and the problems related to present projects of waterworks management system in Korea were analyzed.

Competitiveness to some countries or cities plays a important role as a determined factor in me recent age of international globalization. In view of tourism studies, the potential to develop some regions depends on its own abilities to use and maintain the economic advantages of cities in providing tourism products and services. In spite of this importance of competitiveness, a few research has been done in Korea. Therefore, the purpose of this study is to analyze the comparative competitiveness between coastal metropolitan cities in Korea- Busan, Ulsan, and Incheon, to develop the tourism index and find out urban differences. As a result, the findings of this study will contribute to implementing the promotion of tourism and the network between other cities and attracting the domestic and international tourists.

The objectives of this study is to analyze the competitiveness of fisheries trade between Korea and China, and to estimate strategic seafood export products for Korea-China FTA in fisheries sector. The results of analyses indicate that Korea has comparative advantages in export items such as spanish mackerel, flatfish, cod, roe in frozen fish(0303), and squid, sea cucumber, oyster in molluscs(0307). In addition, tuna in prepared or preserved fish(1604), sea cucumber in crustacean, molluscs and other aquatic invertebrates(1605) have comparative advantage in exporting to China.

This paper examined structural changes in export specialization of Japan, South Korea, Taiwan, and China at different levels of technological intensity. The study found significant differences across these Asian economies, with most pronounced changes for exports with high technological intensity. To account for the changing export specialization, the study applied the classical Ricardian model of comparative advantages to export patterns of Japan and South Korea. We found that the export specialization of Japan was mainly determined by differences in fixed effects across industrial sectors, with changes in relative labor productivity much less important. In contrast, changes in productivity turned out an essential factor for explaining the recent export specialization of South Korea.
