As a result of analyzing the relationship between the smart growth principle and the regenerating factors of the port waterfront city, it was found to be highly related to the port waterfront regeneration plan. Factors that are related to the application of smart growth principle derived from association analysis are as follows: ⯈ community development suitable for walking ⯈ differentiated and attractive community building with definite place, ⯈ open space, farmland, beautiful natural scenery, environmental preservation, ⯈ strengthening and inducing development for existing communities, and providing diversity of transportation options. However, in the Jeju port redevelopment plan, the principles such as ⯈ complex land use ⯈ advantage of high-density architectural design method, ⯈ various housing opportunities and options, etc., need to be applied in implementation design. Since Jeju city and Jeju port possess the strong characteristic features of port waterfront city, so it is necessary to develop jointly applying smart growth principle through integrated port waterfront city regeneration plan.

"Death is the side of life which is turned away from us." The life of people in Seoul, however, is disconnected from death. Why? This article compares the historical changes in the cemetery disposition of Paris and Seoul to answer this question. The cemetery is always a meeting place between the living and the dead. In pre-modern cities, the cemetery was close to the people's daily life. However, the fundamental change of urban structure due to modernization has a great influence on the cemetery. With the advent of the train, the world has shrunk and the city has expanded unprecedentedly. In such a situation, the cemetery is expelled to the outside of the city. However, while Paris and Seoul share the same overall flow, they responded differently to the plans for the establishment of large-scale remote cemeteries. In Paris, the plan was canceled by citizens who value their relationship with the dead. On the other hand, Seoul was unable to manage the cemetery due to social confusion in 20th century. All cemeteries were expelled as industrialization began. As a result, there is no public cemetery or ossuary at present in Seoul. In Seoul, about 20 years ago however, a new kind of place for the dead began to appear. It is an ossuary attached to religious facilities. In other words, the current cemetery of Seoul is divided into two forms : the public cemetery, which is expelled from the city, and the private ossuary, which is attached to religious facilities built in the city.

As the construction standards for energy-saving eco-friendly housing have recently been strengthened, the proportion of window work has increased with the demand for high-efficiency housing. Windows have high frequency of use, and there is the potential for many defects to occur depending on the characteristics of construction. According to a government agency's survey of defects in public rental apartment housing, defects in the windows work accounted for the highest portion of complaints received. Accordingly, related previous studies were considered, and it was found that the existing studies in Korea lacked research that reflected the construction characteristics of window work and the importance of maintenance. In addition, existing overseas studies considered both the constructor and the resident's position, considering the cost aspect together, and showed a trend of structuring the relationship between defects and causes. Therefore, this study will analyze the causes of defects that can occur in the construction phase of the windows work, reflect the construction characteristics, and derive major factors that consider the importance of maintenance based on the possibility of recurrence after repairing defects. Ultimately, this research will contribute to preventing defects in the construction phase and reducing maintenance costs by presenting a highly effective defect management plan through selecting the major factors for each defect type that can be intuitively judged by analyzing the causal relationship between defect types and causes.

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.

Purpose: A city is regarded as an organic living thing that generates, changes, and fades away in relationship with many components of city. Therefore, a city has its own identity based on its historical trace. Among these elements composing a city, it is a square that makes a city more active and dynamic. Piazza Navona in Rome, Italy has played its role as significant core in the city and has distinctive function from other squares in urban ecological environments. In this study, the distinguishing function and role of Piazza Navona will be defined. Another purpose of study is to figure out what factors of Piazza Navona attracts a lot of diverse people and activities. Method: First, general understanding of function, type, and history of piazza; Second, the historical background of Piazza Navona; Third, site analysis related to surrounding environments; Fourth, architectural characteristic of Piazza Navona in terms of plan and elevation; Fifth, comparing with other representative squares in Rome such as Piazza San Pietro, Piazza del Popolo, and Piazza del Campidoglio in aspects of urban function. Result: Piazza Navona provides both citizen and visitors with an inviting place to embrace all kinds of activities including assembly, annual festival, and daily events. Its functions in the urban environments also involve a tourist attractor as landmark, place for social and cultural interaction, market, and place for meeting and leisure. It is attributed to following factors; historical background as the city center since the first century AD; its location in the center of Rome; enough size and flexibility to accommodate many people and various events; open space enclosed by surrounding buildings; historical baroque structures and sculptures of fountains; synergy effect with commercial and other tourist attractors around Piazza Navona; and comfortable accessibility.

This paper presents a tool called Quality-Cost optimization system (QCOS), which integrates Multi-Objective Genetic Algorithm (MOGA) and Quality Function Deployment (QFD), for tradeoff between quality and cost of the unitized metal curtain-wall unit. A construction owner as the external customer pursues to maximize the quality of the curtain-wall unit. However, the contractor as the internal customer pursues to minimize the cost involved in designing, manufacturing and installing the curtain-wall unit. It is crucial for project manager to find the tradeoff point which satisfies the conflicting interests pursued by the both parties. The system would be beneficial to establish a quality plan satisfying the both parties. Survey questionnaires were administered to the construction owner who has an experience of curtain-wall project, the architects who are the independent assessor, and the contractors who were involved in curtain-wall design and installation. The Customer Requirements (CRs) and their importance weights, the relationship between CRs and Technical Attributes (TAs) consisting of a curtain-wall unit, and the cost ratios of each components consisting curtain-wall unit are obtained from the three groups mentioned previously. The data obtained from the surveys were used as the QFD input to compute the Owner Satisfaction (OS) and Contractor Satisfaction (CS). MOGA is applied to optimize resource allocation under limited budget when multi-objectives, OS and CS, are pursued at the same time. The deterministic multi-objective optimization method using MOGA and QFD is extended to stochastic model to better deal with the uncertainties of QFD input and the variability of QFD output. A case study demonstrates the system and verifies the system conformance.

The purpose of this thesis is to understand the shape of The Sijeon (Licensed-Markets) established around the Jongno and Namdaemun-ro Avenues in Hanyang during the Joseon Dynasty in the 19th and 20th centuries and then to examine the relationship with the urban structures of Hanyang City. By investigating the excavation results of the Cheongjin and Gongpyeong areas, drawings, photos, and documentary records related to the city, this study classified the building types in the Jonggak area. As a result, since the 19th century, the basic form of Sijeon with 2 Gan(間, bay) in the front facade and 3 Gan(間) on the side, in other words, 5M in the front and 8M in the side was arranged in parallel, and it was a type with a corridor-type courtyard inside. The inner sides of Jongno Avenue had an atypical flat shape that suited the more free lot, and a courtyard-type plan with a single entrance was also confirmed in the one or two Bang(房, district). This study reflected the operation method of the Sijeon buildings b between the one unit and the other units, which affected the internal spatial structures, and it found that the size and style of the Sijeon buildings were closely relevant to the size of the lots near Jongno Avenue.

To evaluate the value of a preserved tree as rural landscape resource, the growth environment and health condition was investigated, and the image evaluation was implemented on land~ape architectural major undergraduate students for zelkova trees in Yesan-gun. The image evaluation results of zelkova trees were as followings; 1) Typical image of preserved tree examined by Semantic Differential Scale were 'Old', 'Big', and 'Good'. 2) The 'big' image of zelkova tree and the height of tree, the width of tree crown, the breast girth of tree, the root girth of tree, the external formation of tree, and the health of tree bark is mutually related. Especially, the correlation between the 'big' and the external formation and the width of tree crown is high. 3) Typical image of preserved tree examined by Likert Scale were 'Natural', 'Green', 'Peaceful', and 'Rural'. 4) The preservation necessity for preserved tree was highly related with the state of ground, and the management necessity for preserved tree was highly related with contamination level and the state of ground. The appropriate management plan for preserved tree are proposed to improve the quality of rural landscape(basis of these results).

As a portal to rural town, Myeon near large cities is expected to represent image of the rural area. But, the landscape are changing rapidly due to development pressure and to the expansion of the transportation network. For visitors and transit traffic, Recognizing that the characteristics of the streetscape is an important task for the vitalization of the rural district. In particular, it was found that the visual quantity of the central street in the location of the town was closely related to the preference of the streetscape, and the visual quantity of trees and the visual quantity of the building showed an inverse relationship of + and - respectively. Since this is not a simple ratio of the sky to the building, but a relative factor, the possibility of landscape improvement can be improved through management of public facilities or green spaces and maintenance of open spaces or gaps between buildings. It seems that it is necessary to secure separate means for the management of the architectural landscape, such as the establishment of a special landscape plan or establishment of ordinances.

The present study aimed to find a way to create forms that can simultaneously meet several architectural requirements by applying generative design methods specifically focused on cellular automata. In other words, it is tried to find various forms of architecture that all have common features. Because of the useful features of cellular automata, we decided to use it to generate various forms, but make a relation between the discrete nature of cellular automata and the continuous nature of architecture, was the major problem of our project. To achieve this goal, three consecutive stages were designed. In the first stage, independent variables including the location of the building, the height of the building, and the building area were considered as the inputs of the model. In the second stage, after locating the building, the building's main shell was designed as a hidden geometry for the cellular automata and then the cellular automata were determined based on this shell. The main result of this research is establishing a logical relationship between the discrete geometry of the cellular automata and the continuous search space such that it creates various optimized forms. Although we specify the site plan of this project at Iran-Tehran, this research can be generalized to various design sites as well as different projects, allowing the architectsto alter the cell dimensions, cell density, etc., based on their opinion and project needs.
