PAJU Book City Plan was designed to integrate two concepts of "Publishing Productive City" and "Ecological City" with the goal of "bringing of human being and nature together". This research on the post occupancy evaluation on PAJU Book City has two aims; One is to define how people, mainly working there rather than living, recognize the city and the other is to identify the problems resulted from the first phase of planning process and to suggest feasible solutions at the same time. It would be desirable that the outcome of this research should be used as data sources to improve the second phase of the plan. The evaluation criteria were created by the pre-survey on the basis of previous researches and "Pa Ju publishing city architectural design guide book (1999)". With those criteria, on-site questionnaire was conducted among people who work in PAJU Book City and stratified sampling was used for the proper sampling. The result is as follows; the visual-aesthetic criteria had positive response, which also closely related to a city satisfaction. Considering this result, construction type, circumferential environment of the building and a place of building form were found appropriate. The evaluation on the physical-ecological criteria was relatively low. Respondents were unsatisfied with green space and required better ecological waterway and more roadside tree. As green space was given a lot of weight in satisfaction survey, more green urban areas should be planned in the next phase. The evaluation on the social-behavior criteria got the lowest score. Particularly, the accessibility and convenient facilities were remarkably low. Nonetheless, the self-conceit about PAJU Book City was highly evaluated and played a crucial role in a city satisfaction. In order to achieve the goal, physical beauty, characteristics as a publication city as well as an ecologically sustainable city should be main agenda in the second phase of Paju Book City Plan. Consequently, it is important to strike a balance between the external environment and image media in order that PAJU Book City should be re-born as a culture city.

본 연구의 목적은 용인시에 대한 생태발자국 지수 산정 및 변화분석을 통해 용인시의 환경용량 추이를 분석하고, 이를 바탕으로 용인시의 도시개발 및 계획의 방향을 제언하는 것이다. 이를 위하여 용인시를 대상으로 1993년, 2003년, 2013년에 걸친 생태발자국 지수 분석을 실시하였으며, 지수분석 결과를 바탕으로 용인시의 토지이용 변화와 개발패턴의 문제점에 대하여 분석하였다. 또한 GIS(Geographic Information System)를 기반으로 한 토지피복도와 생태발자국 지수의 비교를 통해 용인시 토지이용의 변화를 환경적 측면에서 분석하였다. 본 연구 결과는 다음의 세 가지로 요약될 수 있다. 첫째, 용인시의 총 생태발자국 지수는 1993년 3.20(gha), 2003년 6.50(gha), 2013년 11.15(gha)로 산정되었으며, 이는 용인시의 생태발자국이 세계적으로 요구되는 1인당 생태발자국 1.8(gha)는 물론, 한국 전체의 1인당 평균 생태발자국인 3.56(gha)을 훨씬 상회하는 수준으로, 지역 환경용량에 비해 과도한 자원소비가 이루어지고 있다는 것을 보여주고 있다. 둘째, 1993년부터 20여 년간 용인시의 생태발자국을 부문별로 분석한 결과, 산림부문의 생태발자국이 가장 크게 증가하였으며, 다음으로 에너지 부문, 음식 부문, 건조환경부문으로 순으로 나타났다. 특히, 산림 생태발자국의 경우 1993년에는 가장 낮은 0.002(gha)였으나, 2013년에는 7.32(gha)로 급증했으며, 에너지의 경우도 0.87(gha)에서 2.38(gha)로 비교적 높은 증가율을 보였다. 이는 급격한 도시개발로 인한 목재수요와 목재생산력의 지나친 불균형 및 주거와 상업용지 개발에 따른 에너지 수요의 급격한 증가에 기인하는 것으로 분석된다. 셋째, 지난 10여 년간 생태발자국과 산림 및 건조환경 토지피복의 변화를 관찰한 결과, 산림부문의 생태발자국이 가장 크게 확대되었으며, 실제 훼손된 산림면적 또한 증가된 건조환경 면적에 집중되어 있음을 알 수 있었다. 에너지 부문의 생태발자국 또한 급격한 증가를 보여주고 있는데, 이는 토지피복도 분석에서 알 수 있듯 건조환경부문, 특히 상업시설과 도로 및 철도용지의 급증에 크게 기인하는 것으로 분석되었다. 이는 향후 용인시가 개발 시 산림의 훼손을 최소화하고, 녹지면적을 확대해야 할 필요성을 제기하고 있으며, LPG 등 화석연료의 소비를 줄이는 대신 신재생에너지의 확대를 적극적으로 추진해야 한다는 근거를 제공할 수 있다.

While the ideal universality of the modern period has achieved outstanding results in terms of establishing sanitary cities in contemporary urban environments, it has caused the decline of the genius loci. This study raises the question of the lost sense of place and proposes a solution, 'The Human-Environmental Ecological City'. The Human-Environmental Ecological City, called 'Ecoumenal City', does not provide a fake idealism with the conclusion of modernity of non-place or sense of place without modernity. It is both cosmological and geogenic, and the technology of the time is projected onto it human-environmentally. It does not pursue any more a urban planning as the overall work of an individual, but it aims at a balance rediscovered through the individual spontaneousness.

With the launch of a new millenium of the 21st century ahead, one of tasks that need to be considered in urban ecological aspect is the understanding of impact of continuing urbanization on urban ecosystem, habitats, and various species of animals and plants. In addition, alternatives and measures to mitigate these impacts including environment restoration should be pursued. In this article, the following points will be reviewed; 1) the definition and significance of an eco-city and "ecological network", 2) the necessity of an eco-network as one of factors composing an eco-city, in the aspects of urban planning and urban ecology, 3) ways to build an urban ecological network and example of foreign countries, 4) as an example of a city in Korea, the present state and impending tasks of the ecological network of Seoul city, and 5) a brief conclusion and suggestion. By providing a basic tool called "an ecological network" for urban space planning, it attempts to contribute in promoting networking of cities (netropolis) and urban biodiversity. It is believed that how to create an ecological network in an artificially developed urban area is a pending issue we are faced with. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology. Regarding the efforts to return the Nature to urban citizens, there is a need to view the development of a desirable urban ecological network as the starting point and finishing point of the effort. In this way, it is believed that the objectives of urban sustainability through netropolis development would also be achieved.

Urban land consolidation, which is to reform land parcels to remove fragmentation and produce ideal blocks, is an effective means for urban renewal. Successful urban land consolidation brings out great benefits to the city officials as well as general public, such as improved city image, increased land value, and more effective land use. However, urban land consolidation can be detrimental to environment, especially in the ecological aspects, while the execution of land consolidation has been focused solely on development for the sake of human benefits. To remove negative effects of urban land consolidation to the ecological system, this paper is intended to establish a set of criteria for evaluating ecological impacts of an urban land consolidation plan. Firstly, key ecological indicators are identified using a special group decision-making process called "habitual domain analysis" and then individual weighting of each indicator is recorded by analytical hierarchy process. An urban ecological evaluation model with 4 levels and 23 indicators is thus developed.

Industrialization and development of technology satisfied various humanly needs and lay the basis of numerous benefit and profit. New technologies like these mostly required large amounts of fossil Fuel, Fossil energy depletion rate was increasing rapidly. However, technical development for Human race required absolute sacrifice of the environment. Especially, 'City' which had been focused as stage of human activities, allowed to continue to have fossil energy dependent activities, and it shows in many data that the city is responsible for the 75-80% of the green house gas by human. In order to solve the problem relating climate changes and energy, European countries already made progress studies on many of the low carbon green city and pilot case construction. Especially, Germany, Austria, Holland, Sweden who had been playing leader role on environmental awareness and ecological concept, are actively constructing low carbon green city project based on Ecological city planning scheme. These projects positively utilize planning scheme that limits carbon emission using Urban Metabolism concept. Therefore, throughout this study, I would like to present planning and direction of future domestic low carbon green city by analyzing theories relative theories and best practices in Europe.

It is certain that urbanization has transformed the ecological consequences severely, but urban ecosystem is not fully understood yet. Urban growth is not like a static form and it spreads spatially and temporally. Therefore in studying urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. Using gradient analysis, we attempted to quantify the urbanization's spatial impacts in Daejeon-city and Cheonan-city, Chungcheong-province, Korea. Because of Multifunctional Administrative City Planning (MACP), a lot of development projects are planned in Chungcheong-province, Korea. It's important to study about original cities' patterns and impacts. These results can be adopted to future city planning. So several measures such as fragmentation, vegetation index, surface temperature, population density, and income rate were computed along a 75km long and 3km wide transect. The results showed that Daejeon-city has a wider urban center, lower vegetation indexes, and higher surface temperature than Cheonan-city. Therefore in the perspective of urban environments and sustainable urbanism, it seems that Cheonan-city is better than Daejeon-city. The changes along the transect have important ecological implications, and quantifying the urbanization gradient is an important step in understanding urban ecology.

The concept of Eco-city is to protect the city against development, trash, and industrialization. But the sprawl phenomenon of urbanization and industrialization are accompanied by the environment destruction. Therefore the importance and definition of eco-city were suggested. And to restore the urban ecological network, the prototype direction of eco-city at YongJeonDong in DaejeonCity were suggested in this study. It is believed that how to create an eco-city is an artificially developed $\square\square$Yong-Jun Dong$\square\square$ is a pending issue we are faced with situation.
