In this paper, we deal with the TSP (Traveling Salesperson Problem) which is well-known as NP-complete optimization problem. the TSP is applicable to network routing. task allocation or scheduling. and VLSI wiring. Well known numerical methods such as Newton's Metheod. Gradient Method, Simplex Method can not be applicable to find Global Solution but the just give Local Minimum. Exhaustive search over all cyclic paths requires 1/2 (n-1) ! paths, so there is no computer to solve more than 15-cities. Heuristic algorithm. Simulated Annealing, Artificial Neural Net method can be used to get reasonable near-optimum with polynomial execution time on problem size. Therefore, we are able to select the fittest one according to the environment of problem domain. Three methods are simulated about symmetric TSP with 30 and 50-city samples and are compared by means of the quality of solution and the running time.

Landscapes and gardens have emerged as an important medium of practice in contemporary cities. Among them, this paper examines the city through the frame of gardens. This is because gardens are being reconceptualized as a medium of activity for urban residents and have become an important subject of action in urban regeneration and the creation of urban villages. From this perspective, this paper examines and proposes an "integrated garden city theory" as a landscape theory suitable for the contemporary era by focusing on the urban structure and the behavior of urban residents through the medium of gardens, as well as the process and results. This is both a process and a result of looking back at the evolution of landscape for over a century and rethinking the identity of landscape. We first examined garden city theory, noting that Ebenezer Howard and Frederick Law Olmsted's positions on the relationship between gardens and cities were not so different, and that "working and responsive landscapes" were fundamental to cities and the beginning of landscape theory. We also examine how their ideals have not been fully realized in cities over the past century, but the prototype of gardens based on traditional garden culture is now being formed in East Asian cities, and the evolution of landscape theory in response. The conclusion is that a new version of the garden concept should be reestablished as a living infrastructure in our cities, and a new garden city theory is needed to make it work. To this end, each chapter examines three arguments, as follows First, the values of gardens and East Asian garden cultures in contemporary cities are shaped by the themes of community and integrity. Second, Korean communality, represented by apartments, is expressed through gardening and requires the reconciliation of city and life and the role of landscape architecture as a specialized field to support it. Third, we examine and consider an integrated garden city theory as a theory of practice in which city-based, everyday life, and garden mediums, i.e., city, life, and garden, are organic, based on an oriental view of nature. As a result, it is confirmed that contemporary gardens and cities are looking for important elements and values that still need to be rediscovered in East Asian landscape and garden cultures. Although the proposal of an integrated garden city theory cannot guarantee the continuation of landscaping, it can be an opportunity for all fields related to cities, not just landscaping, to collaborate and consider garden cities. Through this, it is hoped that "the concept of garden and city suitable for metropolitan or dense cities, ways to spread and support garden culture based on community, evolution of landscape theory/design theory suitable for lifestyle and terrain conditions, search for sustainable/resilient garden city theory that can respond to climate change, and establishing a new role for landscape in the 21st century" will be seriously considered.

This study examined urbanization effects and the causes of urbanization, urban population growth, increase of the city scale, land cover change, and human cultures and economic activities, using the daily minimum temperatures of the past 50 years (1961-2010) with the subject of Busan and analyzed correlations between urbanization effects and the causes of urbanization. Thereby, this paper drew a conclusion as below: 1) Due to the urbanization effects, the average annual daily minimum temperature increased as about $1.2^{\circ}C$; however, except for the factor of urbanization, the increase was shown as about $0.2^{\circ}C$. The occupancy of urbanization effects in the total temperature increase was quite high as about 83%. 2) Just like other cities experiencing urbanization, Busan, too, sees population growth and the expansion of city area as well as increased urbanization effects. First of all, correlation between population growth and urbanization effect was high as 0.96 before 1985 while it was lowered as 0.19 after 1985. Also, correlation between the increase of city area and urbanization effect was high as 0.64 and 0.79 before and after 1985. 3) Regarding the correlation between long-term land use change and urbanization effect, urbanization effect was affected greatly by the increase of city area (0.97) and reduction of green area (0.92). 4) Concerning human activities possible to affect the climatic factors of a city, this paper found the following factors: road length, car increase, power use, and the consumer price index, etc. And regarding the correlation between the three factors and urbanization effect, the correlation was higher in the consumer price index (0.97), the number of registered cars (0.89), power use (0.75), and road length (0.58) in order.

Fresh Kills is the largest landfill in the world located in the west side of Staten Island, New York. The landfill served as a storage area for New York City's trash for more than 50 years. After years of civilian and political pressure, state and local legislation decided its closure of landfill operation in Fresh Kills in March 2001. Soon after, Department of City Planning announced a Fresh Kills international design com-petition: 'Landfill to Landscape'. The winning entry was promised to be outline for the redevelopment of the 2,200 acre site which the size of three times Central Park. Forty-eight teams representing more than 200 offices from around world submitted proposals, from which six finalists that mostly led by landscape architects were selected. In December 2001, a jury of architects, landscape architects and city officials unanimously selected Field Operations as the winner. The plan, named Lifescape, visualizes the gradual 20-year transformation of the whole Staten Island into a 'natural lifestyle island' recognizing that Staten Island is home to coastal wetlands that shelter one of the most diverse ecosystems in the New York metropolitan area. It suggested that an ecologically reconstituted Fresh Kills could become the center of integrated parks and greenways system on the island otherwise fragmented. The project will be one of the largest and most ambitious undertakings in the metropolis in years developing a complex web of habitats and parklands on top of mountain of trash. This study tries to achieve two goals: One is to provide general explanations on the project, Lifescape, breaking down to its background, geographical context, design concepts and phased development plan. Another is to introduce the unique and innovative design approaches by Field Operations that are different from a conventional landscape architectural attitude. Since this project was well published through many magazines and newspapers, main focus will be upon aspects that differentiate this project from usual landscape projects. Conceptually Lifescape brought provocative notions on nature/culture relationship and the role of urban park as an active agency rather than just a green rest area. Also this project introduced pioneering graphics like plan collage, diagrammatic plan, phasing diagram and photo montage as vehicles conveying information, imagination and provocation. Witnessing the influence of the project gradually in the field of academic and practice in the States, this study is intended to become a constructive reference to similar landscape projects dealing with large and complex urban context in conjunction with restructure of contemporary city.

This study was carried out to develop the close-to nature construction technology for the stream which has been improved just for the flood control with artificially straightened and concrete covered, losing the various functions of the stream such as wild-life habitat, polluted water purification and waterscape. Jungpyung stream in youngin City, Kyunggi Province was selected as a case study site. The results were as follows; 1. Existing stream improvement planning could accept the close-to-nature techniques of the low-flow revetment, keeping the capability of flood control and water use. 2. The low-flow revetment was planned and executed to the bottom of the stream without damaging the existing bank, and the slope of the low-flow revetment was adjusted as 1:1.2∼1.5. Consequently it would not disturb the water flow when the flood occurred and it would keep the constant water flow even at the drought with providing a stable ecosystem and water purification. 3. Low-flow revetement was planted with Salix species and perennials naturally, and it would be a precious biotope for the diverse floras and faunas. 4. Some furnitures such as stepping stone bridge, wooden bridge and step were installed to the suitable locations for the convenience of users, and it will be ot only the sound stream environment but also easy access to the waterscape. 5. This case study site will be monitored for 3 years systematically after the construction was finished in September, 1999 to get the exact results for the scientific approvement

Development of index for evaluation of environmental nature and its application for the purpose of construction of industrial complex with environmentally friendly. Industrial complex comes to be recognized as a disgusting zone according to the increasing environment consciousness of residents. And the objection about the exploitation of geographically unwanted land site is increased during development process and it is possible to cause Nimby phenomenon. Therefore, ecology and environment-oriented strategies tends to be adopted for industrial complex development. Furthermore, the maximization of profit mainly directed by enterprises as of today cannot guarantee its future and the efforts of adopting environmental constancy and harmony as a new objective are made progressively. For the development of city and region, in particular such as residence complex, farming and special city, the discussion of environmental consistency, new paradigm with environmentally friendly is briskly under progress, but the relevant discussion for the development of industrial estate is not done so much. Just only few studies are realized from the viewpoint of industrial ecology but its level remains in the understanding of the concepts and presentation of development direction. This study is to prepare for the foundation of the construction of industrial estate with environmentally friendly under the current condition of Korea against coming future environment era and to try to develop of evaluation range and index which are the basis of evaluation of environment. I applied the above evaluation index to the residents of actual industrial estate to understand their consciousness of decreased environment. And I obtained 7 evaluation ranges and 37 evaluation indexes for the relevant residents. Among them, I get the value less than the average in 19 index items. And they represent very sensible reaction about environment pollution including decrease of waste materials. This study has several limits but is meaningful in that the development of evaluation index for environmental nature in industrial complex is done, and that the basic discussion of the plan and design for environmentally friendly industrial estate is made under the above evaluation and that 37 evaluation items are applied to the reality.

The purpose of this study has two folds. For the local government it gives a guide to establish the housing information system, which provides various housing information in order to promote service to the public on Internet. It also gives a guide for the local government to collect the fundamental data from local housing market and provide them to the policy makers as well as the housing producers (landlords, builders and owner-occupiers). Contents of housing information system website for the local government consist of three main parts. The first part provides housing policy and local housing market information to the upper level local government as well as housing producers. The second part provides housing information for the people who are looking for houses to move the own. Final part provides the procedures of building construction and development plan for landlords to the public. In case of Pyongtaek-City, this study makes them by cluster analysis of houses and households moving pattern as the Internet contents. Housing markets of Pyongtaek-City divide 3 sectors by housing type, tenure type and housing supply ratio etc. And populations prefer to move intra sectors. According to this information, policy-makers should define local housing problems and find solutions and housing producers can supply the house just in sites and in time. In conclusion, local government should provide valuable housing information based on local housing market research to the public for the effective housing policy. As local housing market is formed by various factors it is needed for local government to research housing sub-markets due to apply these research results to the local government for the future.

The era of globalization has ushered in dramatic changes in the past decade covering a wide range of distinct political, economic and cultural trends whereby people adapt their houses to suit their needs and desires. This paper discusses the process of change analytically, emphasizing the importance of understanding the transformation of Lao traditional houses and its impact factors to the transformation and adaptation to suit with globalization trend, and conservation of the characteristics of traditional houses. This study takes place in Luangprabang, an ancient city of Lao PDR, which was designated as a world heritage city in 1995 as it is rich with diverse, tangible and intangible values. Five cases of traditional house in Luangprabang are examined to understand their transformation through time, by analyzing the basic spatial formation, components and elements, especially to find out the impact factors to such transformation. The study revealed that the transformation of the traditional house is subject to not just one single factor, but to a number of factors, where globalization, regulation, economy, and social aspect factors play a prime role and are the root for all these changes. The case study also indicates that these changes are connected to the benefits of income generation as a survival strategy for the low and middle-income people in Luangprabang as well as the housing demands. In the transition period a new residential type appeared accordingly, in which living spaces were categorized according to their general functions. There was a harmony between people's needs and the physical characteristics of the house.
