Now, the population and economical power is deeply concentrated to Seoul-metropolitan region, therefoere the provinces is so lagging behind and the country cannot get balance development. And, like metropolitan region, the more outer the living area of local wide-area city is spreading, the more serious wide-region transportation problems are. But the railroads near wide-area city fun seldom commuter train, so they cannot absorb the transportation demand of wide-area city metropolitan region. To solve above transportation problem, local wide- area cities try to make a subway or a light rail transit. But it is so difficult because the limit of public finance and original small capacity of light rail. In the paper, I propose 'Local city wide-area electric railways' system of the consortium of 'Local wide-city and province transportation union', Korean National Railroad (KNR) and local capital. A 'Local wide-city and province transportation union' operates commuter railways directly using the facilities of KNR, and local capital invests to the stations of above railways system. Therefore the commuter railway system around local wide-city region will be constructed quickly and the stations will be the strong point of local development and investment.

This paper aims to draw essential facts of network city, to analyze the urban corridor in South-East region, Korea, as a network city. Firstly, the characteristics of the network city is examined theoretically. The global economy is developing an innovative class of network cities. A network cities evolve when two or more previously independent cities, potentially complementary in function, strive to cooperate and achieve significant scope economies aided by-fast and reliable transport and communications infrastructure. Network Cities place a higher priority on knowledge-based activities like research, education and the creative arts. Each constituting city stands to benefit from the synergies of interactive growth via reciprocity, knowledge exchange and unexpected creativity. Secondly, we discussed the network structure of cities in South-East region, Korea itself intensively. We survey the network location and outline of the urban corridor in South-East region, spatial specialization and interaction between the constituting cities. We also discussed the problems of the network cities in South-East region, Korea and introduced the desirable policies and alternatives. We can ascertain from the case study of cities in South-East region that the cities in South-East region corresponds the network city model fairly.

The aim of this paper is to explore the formation of the Seoul-focused network city for technological commercialization compared with Seoul as a mega city. The growth of Seoul and subsequently, the Seoul metropolitan region as a mega city and mega region has led the uneven regional development in Korea since the 1960s. To reduce a huge gap between the Seoul metropolitan and the non-metropolitan region, the concept of network city can be suggested in terms of the functional and spatial division of labor. More specifically, such division of labour throughout the formation of the Seoul-focused network city concentrates on technological commercialization which is deeply concerned with R&BD (research and business development). For this network city, there are 4 axes such as the axis of South-North Korean cooperation (the axis of R&BD for complex technologies), that of the expansion of a mega city (that of R&BD for green growth technology), that of the linkage of small and medium-sized cites (that of R&BD for life science and technology) and that of megalopolis (that of R&BD for basic technology) with regards to the axis of urban development and technological specialization. It shall be argued that the formation of Seoul-focused network city can be an alternative to the contemporary uneven regional development between the Seoul metropolitan and non-metropolitan region in Korea.

An analysis of the throughput and stability region of random access systems is currently of interest in research and industry. This study evaluated the performance of a multiuser random access channel with a retransmission gain. The channel was composed of a media access control (MAC) determined by the transmission probabilities and a multiuser communication channel characterized by the packet reception probabilities as functions of the number of packet transmissions and the collision status. The analysis began with an illustrative two-user channel, and was extended to a general multiuser channel. For the two-user channel, a sufficient condition was derived, under which the maximum throughput was achieved with a control-free MAC. For the channel with retransmission gain, the maximum steady throughput was obtained in a closed form. The condition under which the random access channel can acquire retransmission gain was also obtained. The stability region of the general random access channel was derived. These results include those of the well-known orthogonal channel, collision channel and slotted Aloha channel with packet reception as a special instance. The analytical and numerical results showed that exploiting the retransmission gain can increase the throughput significantly and expand the stability region of the random access channel. The analytical results predicted the performance in the simulations quite well.

This paper reviews literature on urban connectivity, and reconsiders the concept of polycentric urban region and its analysis methods, and then, applying them, explores the inter-city flight connectivity and polycentricity in the Yeongnam Region. As results of analysis, it has been identified that the entropy index shows a relatively dispersing pattern of the urban network of the region, and that the dominance index reveals a more polycentric (that is, less hierarchic) character of the region than that of the Capital Region, while some differences are found among individual cities in the symmetry of connectivity and the dominance and/or dependence index. Even though flows of products in textile, basic metals, and automobile industries in sub-divisions of manufacture appear a pattern of concentring into the first central city, the urban network of the Yeongnam Region in general can be characterized as a polycentrism, and policy for polycentric regional development would be suggested.

The Netherlands is a human-made country and an extremely well-designed European country as well. The general Dutch spatial planning for the city and environment takes place at a regional level. The local community determines the primary development conditions, and the prospect is included in a legally binding land-use plan. Especially, Rotterdam is a representative port city as the center of world trade and the gateway to western Europe. According to the history of war, the city reconstruction and the movement of the port area have led to a general change in Rotterdam and the regional redevelopment project on the southern port area of Mass river for the expansion of city functions and the balanced development. The research purpose is to understand the spatial development of the Netherlands city-region based on the analysis regarding the Kop van Zuid project, which is a representative implemented case in Rotterdam. The theoretical framework is the five dimensions and twelve indicators of territorial governance from the TANGO research project by the EU. The target case is assessed by planning and social aspect, respectively, and the results are discussed based on the theoretical framework. This research has the possibility to be utilized as advanced research by the European perspective for spatial development in other city-regions with the port area, such as Incheon and Busan in Korea.

This paper first introduces the concept of image as a key factor in recognition, and city identity as the dominant image of a region which is commonly possessed by individuals living and working in the region. Then, the new approach toward planning, the notion of self-organization associated with images and positive feedback mechanisms in terms of city vitalization, is discussed. Thirdly, carrying out the case study of a process in which Iida City in Japan has acquired a city identity as a puppet drama town, we present four stages in planning for city identity four stages and discuss the phenomena of city image self-organization. Finally, it is pointed out that multimedia are effective measures for the promotion of self-organization of city images, and that the role of local governments is very important in city planning to support the self-organization of cities.

This paper explores changing concept of city in the context of globalization with innovation city and examines the characteristics of innovation city along with regional and national competitiveness. It is agreed that construction of innovation city by relocation of public institutions for balanced development of the country has valid logic. However, there are weak possibilities of innovation within the innovation city. Further more it is not a proper solution for the level up of national and regional competitiveness through this policy. The main logic is that physical relocation of institutions do not guarantee innovation of region through integration into globalization network resulting from the scale difference between nation and globe. Rather this paper suggests that regional innovation policy should performed in accordance with regional conditions and for the better competitiveness of nation and region, decentralization of power is needed. Then a region could have connection with global pipeline based on endogenous development power.

This paper is to provide some suggestions to complement and extend theory of network city, and to consider preliminarily its applicability for development of the Yeongnam region, exploring its normative implications for urban and regional policy and its significance of empirical research. In order to resolve some limitations and problems of network city theory and of empirical research, we need to reconsider systematically analysis methods, to extend indices of connectivity, to reconfirm normative characters inherent in network city theory, to suggest the constitution of cooperative governance, and to develop policies for embedding functional connectivity into internal community. In a preliminary analysis of Yeongnam region on the basis of network city theory, it is not clear whether the urban system of the region is entirely a type of network city, even though it seems to be close to network city. However, in order for the Yeongnam region to orient towards network city, we can point out importance of policy issues such as expansion of transportation and communication infrastructure, strengthening of economic connectivity, constitution of cooperative governance, and local embeddedness of functional network within the region.

The aim of this research is to survey the census of street trees and to provide remedial measures for street trees management to Miryang City. To do this, survey was carried out 16 region units in Miryang City. Through the survey, the current status of street trees’ map was made using automated map. From the results, it is turned out that 17,079 trees have been planted in Miryang City. The major species of street trees are Prunus serrulata var. spontanea(41.6%), Ginkgo biloba(26.1%), Pinus thunbergiana(13.3%) and the others are 12 species(19.0%). By the region units, Samrangjin-Eub is the most that 2,308 street trees are planted, and the next is Chodong-Myon(2,206 trees). The littlest street trees planted region is Cheongdo-Myon. In the results of comparison the component of street trees with other municipal cities, e.g. Seoul, Incheon, Kwangyang etc., only a few street trees have been planted so many in Miryang City. So, Miryang City indicated high proportionate street trees planting ratio. The suggested remedial measures are consisted with identifying the each street, increasing the green area by accepting the suitable street tree planting model, improving the physiological growth condition and systematic management with GIS.
