Although design industry belongs to one of the creative industries and contributes significantly to urban cultural economy based on its cluster formation, researches on design industry are rarely made explicit from the perspective of creative industry cluster. After reviewing the life cycle of design industry clusters in Euljiro and Hongdae Area in Seoul, this study compares these two clusters with respect of diverse dimensions of creative industry cluster such as agglomeration economy, spin-off activities and institutional environments. Research methodology includes the analysis of ?Seoul Business Statistics? and the in-depth interviews with 14 professional designers. The result shows that design industry cluster in Euljiro is close to the traditional industry cluster mainly dependent on printing industry with very limited impact on urban economy, while Hongdae Area develops creative industry cluster by virtue of university spin-offs, art markets, hybrid cultural consumption spaces and the active participation of designers contributing to urban economy in diverse ways. This comparative analysis highlights the importance of various environmental components to encourage creative activities in developing the creative industry cluster.

Recently the World Bank released its World Development Report 2009 (hereafter WDR 2009) with the title 'Reshaping Economic Geography.' In the report, the Korean experience in regional development policy was highly praised. Also, the current government has been trying to reshape the regional development policy in view of 5+2 Economic Regions. The main theme of this paper is how to establish the highly valueadding economic system and how to deal with scale economies for regional development. In this paper these tasks in Korea's regional policy were discussed with reference to the WDR 2009. Enhancing the density of the central city of each Economic Region, reducing the economic distance between cities and rural areas, and getting rid of the barriers to cooperation between provinces are the keys for the efficiency and the effectiveness of the regional policy. In addition, strengthening the national solidarity through collaborative development of 5+2 Economic Regions still remains as one of the major tasks of the Korean government.

Dynamic response and economic of a laminated porous concrete beam reinforced by nanoparticles subjected to harmonic transverse dynamic load is investigated considering structural damping. The effective nanocomposite properties are evaluated on the basis of Mori-Tanaka model. The concrete beam is modeled by the sinusoidal shear deformation theory (SSDT). Utilizing nonlinear strains-deflection, energy relations and Hamilton's principal, the governing final equations of the concrete laminated beam are calculated. Utilizing differential quadrature method (DQM) as well as Newmark method, the dynamic displacement of the concrete laminated beam is discussed. The influences of porosity parameter, nanoparticles volume percent, agglomeration of nanoparticles, boundary condition, geometrical parameters of the concrete beam and harmonic transverse dynamic load are studied on the dynamic displacement of the laminated structure. Results indicated that enhancing the nanoparticles volume percent leads to decrease in the dynamic displacement about 63%. In addition, with considering porosity of the concrete, the dynamic displacement enhances about 2.8 time.

The purpose of this study is to provide implications for regional development policy, especially peripheral regions, by investigating the agglomeration process of regional resource-based industries. In the process of globalization, the region emerges as an actor which participates in competition in the global market. Developing regional resource-based industries is an important tool to develop regional economy. This study examines the agglomeration process of the fermented soy products industry in Sunchang in historical approach and finds out success factors of regional resource-based industries. Then policy implications for regional development by developing regional resource-based industries are drawn and suggested.

This paper examined, using three indicators, urban area rate, urbanization rate and urban population density upon the status of urbanization since the 2000s in Southeast Asia. This study also carried out an empirical analysis on the effects of urbanization on economic growth using the Williamson's inverted U-shape hypothesis. In addition, this study calculated the thresholds by which urbanization starts to have positive effects on economic growth by using estimated coefficients, and comparatively analyzed each Southeast Asian country's status. The empirical analysis results opposite to the Williamson's hypothesis. This means that the hypothesis asserting that urbanization has positive effects on economic growth in a country with low economic development phase and income level, but that urbanization can have negative effects on economic growth, if a country's income level is beyond a certain level(threshold), is not supported in this study. In summary, the economies of agglomeration represented as localization economy and urbanization economy is realized to some degree in terms of urbanization in Southeast Asia. Also, urbanization in Southeast Asia has positive effects on economic growth through knowledge spillover, the active exchange of ideas and productivity improvement. In examining the meaning of Southeast Asia's urbanization, policy consideration needs to be conducted, and efforts should be made to maximize the positive effects of the economies of agglomeration and knowledge spillover on economic growth.

Globalization of economy has a significant impact on the organization of economic Space. This paper examines the concepts of globalization and localization, major trends of the changes in the organization of economic space in the Pacific rim, and the major processes of the changes. Intra-regional trade and foreign direct investments have increased considerably in the Pacific region with the progress of globalization during the last decade. Due to the Progress of globalization of economy in the Pacific rim, some growth triangles have extended their agglomeration area beyond the national boundaries and several new industrial districts have developed. The reorganization of the economic space in the Pacific rim has been resulted from industrial restructuring of NIEs, spatial division of labor along the commodity chains, and the formation of industrial networks within the region. The ‘cooperative network strategy’has been suggested to minimize the negative effects of glocalization and for the sustainable development in the Pacific rim.

The rapid innovation of information and communication technology and its sharp falling prices have brought about the expansion of the Internet, integrating the world as one space under converged space and time. This rapid expansion of the Internet and its application in the economy have spurred the emergence of the digital economy. The Internet has influenced strongly on the changes of not only economic activities but also political, social and cultural activities. In this context, a rapidly increasing Internet expansion renders the rhetoric about the death of distance and about the meaningless of geographical place. However, the development and expansion of Internet induces a growing digital divide among nations and also a spatial inequality in a nation as the supply of the Internet has concentrated towards demand-affluent large cities. A large gap of digital access has been occurred between high income and low income countries according to a measurement of the international digital access index. In a national level, the Internet backbone has been built around large cities which favor a large amount of the Internet demand, and the affordable accessibility of these cities for the Internet services has influenced strongly on the agglomeration of Internet related industries, further inducing the construction and investment of the Internet backbone into large cities as cumulative causation effects. As a result, the expansion of the Internet affects immensely on the changes of spatial structure in a nation resulting in the new spatial phenomena such as centralization, concentration and splintering in the digitalized space-economy.

As diesel engines have high power and good fuel economy on top of less $CO_2$ emissions, their market shares are increasing not only in commercial vehicles but also in passenger cars. LNT, urea-SCR and combination of them have been developed for after-treatment of the exhaust gas to reduce NOx on diesel vehicles. The aim of this study is to investigate the $NH_3$ generation characteristics of LNT catalyst downstream. It was found from the experiments of the LNT catalyst that $H_2$ was useful as a reductant in SCR catalyst because it can enhance the de-NOx performance and improve $NH_3$ selectivity. The $NH_3$ generation of the LNT, when hydrothermally aged at $900^{\circ}C$ for 18 hr, increased to about 90ppm at $300^{\circ}C$ due to Pt sintering and Ba agglomeration. LNT catalyst was most sulfur poisoning at $500^{\circ}C$. The $NH_3$ slip increased due to the reduction of residence time according to SV increase.
