This research investigates the design process of free-form architecture to understand the design strategy and changing factors during the development phase and the cause for them. It is aimed to foresee the changing factors from the design process and to reduce design changes. It analyzes the design changes of free-form architecture based on projects with finalized documentation or under construction in South Korea. Many free-form shapes of the free-form architectures have to be adjusted to rigid-form in order to satisfy function and be economical to build. The research finds three patterns in design changes. First, from the factors for design changes: function, constructability, design, program add/subtract, efficiency, circulation; Function and Constructability are the higher factors compared with the rest. The two are the design changes suitable for actual usage and cost savings. Second, each project has different predominant factors for design changes as the degree of free-form is different. Contrary to initial expectation, the greater the degrees of free-form of the competition scheme, the higher the rate of Function among the factors for design changes. Constructability is higher when the degree of the free-form is less than others. It means that the lower the degree of the free-form, the more properly planned the space of the building is. Last, Constructability of free-form architecture is considered during the earlier design phase than definite-form, one by which the design changes by comparing 'Before fixed Space Program' (BSP) and 'After fixed Space Program' (ASP) design changes. The research would be helpful as a reference for setting up competition guidelines to reduce trial and error during the design process.

The Saemaeul Movement, which is the representative national campaign of Korea aimed at the development of local communities, has drawn a great deal of attention from home and abroad and formed an element of Korea's national brand since 2000. Accordingly, this research was conducted for the purpose of constructing a memorial park in Shindo Village, Cheongdo County, North Kyoungsang Province, which is a home to the Saemaeul Movement. As the Saemaeul Movement is benchmarked by many countries around the world today, this research aims to communicate the spirit and social value of the movement and disseminate its effects of local community development in rural areas through the construction of a memorial park. In this study, the design motive of the memorial park was conceived through the historical review and case studies of the Saemaeul Movement. In parallel, theoretical study was also conducted on design techniques as the basis of this research. In consideration of the characteristics of a technical article, this research was conducted in several phases. In the first phase, the conditions of the site where the park construction was planned were analyzed and the direction of its development was set. In the second phase, the main theme and the basic principles of planning were established, and the contents of the park construction project were devised in detail. In the last phase, a comprehensive plan was established, including a space layout to accommodate activities, facilities and programs to be introduced to the park. The park construction site ($106,000m^2$) was divided into four zones (memorial zone, historical theme park, education zone and experience zone) based on circulation planning aimed at creating memorial space, and was linked to eco-friendly ecological space in consideration of environmental features. At a time when the Saemaeul Movement is being propagated across the world, the result of this study will help create a place for its memorial and play a pivotal role to boost international movements aimed at promoting co-prosperity across the global village. It will also bear significance as an example of theme-based park construction in a rural area and the invigoration of a local community.

This study aims to derive street design alternative which can be applied to residential area as the functions of land use have been changed. The main findings are as follows; First, the study area in this research is on the process of the functional transition from full residential use to residential-commercial mixed use with cafes and restaurants. Second, dead-end streets in residential areas needs to be widened in order to meet the increasing needs of pedestrians and cars. One of the suggested strategies is to remove fences on the dead-end streets. Third, based on the main findings, this research can suggest following policies. Citizen participation is necessary in building land use plans and space design in old residential areas. Citizens can participate in architectural and landscape contracts, district-unit plan with the help of experts such as urban planners and architects.

Salk Institute for Biological studies is widely considered as architectural masterpiece of Louis Kahn's. Its iconic plaza with symmetrical concrete structures, overlooking the Pacific ocean in La Jolla, has been acclaimed as a facade to the sky. Little has been written on Kahn's achievements in the building system integration in order to bridge the gap between technology and design. This paper explores the technical issues, the design intents, and the major building systems to identify the Kahn's integration methods between building systems. The project is analysed into four major systems; structure, mechanical, envelope, and interior system. The integration methods of building systems are investigated in physical, visual, and functional aspects. The most distinguished cases of building system integration are the introduction of the interstitial floors between the laboratories and the creation of the smooth and warm materiality of exposed concrete walls. Kahn proposed open floor plans for the laboratories which are capable of easily adapting to changing needs. He also introduced the interstitial floors which are framed of the vierendeel truss systems and deliberately overlapped the structure systems with the mechanical systems such as ducts, water pipes, and electric conduits. The exposed concrete walls mixed with pozzolan ashes look very much like granite or limestone as the result of the physical and visual integration between structure, envelope, and interior systems.

Biomimicry architecture has been highlighted in recent years for the innovative ideas from the nature have provided main developments in many areas. The related studies in Korean architecture is entering the first step and are needed close attentions for its vitalizations. This study starts with the acknowledgement of necessity to establish the architectural application process. First of all, it is named as a 'Passive Cycle' if a problem-solving or a project has been through the analysis of process complexity and biomimicry application process in other areas. Then, the basic frame is structured as a 'Process-Cooperation,' which integrates process complexation with process circulation. The cooperative relationship starts from the beginning of the design with not only professionalists related with architecture but also ones in various areas when it is issued a difficult problem or high environmental performance not found in common architectural design processes. To make the architectural application good progress, the characteristics of bio-mimetic architectural applications are categorized as three areas; the expected effect, the application level, and application method. As a result, the organic complexity should be prioritized to have bio-mimetic application effectively while accessing the principles. Therefore, the process for the architectural application of biomimicry is suggested as 'Organic Cycle-Cooperation.'

The purpose of this study was to examine the selection process of the marathon course and the progress of the related urban landscape design projects. The study revealed that the initially selected course of the downtown Namdaemum changed to the riverside course that runs around Gangnam and Han river. This change implied that showing the developed landscape of Seoul was much more considered than showing the traditional landscape of Seoul. The urban design plan had changed in 1986 after the marathon course was finalized. The development project of downtown was changed to Gangnam area including Teheran-ro. The city also redeveloped the substandard housing zones around the Olympic facilities. As a result, developed areas and modern apartments of the riverside was emphasized in international TV game broadcast. This embedded the industrialized and modernized image of Seoul to foreigners. Also, Koreans started to recognize the Han river as Seoul's representative landmark. Accordingly, Seoul succeeded in creating a modernized urban landscape image through the Olympic marathon course.

Under climate change and urbanization, rainwater harvesting (RWH) systems are emerging as an alternative source of water supply because of growing concern about water sustainability. RWH systems can satisfy the various watering needs and provide the environmental benefits of lessening the damages from flood, drought, and runoff. The economic success of a RWH system is vitally concerned with the determination of the design capacity of storage tank to be built in the system. The design capacity is determined by the factors of average annual rainfall, period of water scarcity, and water price during the whole life-cycles. Despite the high uncertainties inherent in these factors, the current engineering design of RWH system construction often assumes that storage tanks should be built all at once. This assumption implicitly ignores the managerial flexibility in responds to the future as new information comes out-the right to build storage tanks stage by stage depending on the evolution of demand. This study evaluates the value of a multistage storage tank construction using a real option approach. A case study involving a typical RWH system construction in Jeonju, the Republic of Korea is conducted. The managerial flexibility obtained from the real option perspective allows engineers to develop investment strategies to better cope with the issue of water sustainability.

The Fagus Factory at Alfeld on the Leine in Germany, which was built in 1911 and 1914, is a well-known and very important object in the history of modern architecture. Alan Colquhoun mentioned that it is "prophetic of the 'objective' (sachlich) Modern Movement of the 1920s". Vittrio M. Lampugnani evaluated it as "a Pioneer building of the architectural Realism". Most of historian of architecture explain that these achievements were accomplished mainly by the master architect Walter Gropius and sometimes by his co-worker Adolf Meyer. Through investigating the background in the planning stage and the process of design it is to try to find out what is truly happened during the project time. Furthermore, historical meanings of the building in the modern architecture is reinterpreted in the following aspects; who or which elements have influence on the Fagus Factory? and what kind of problems can be caused by the digested architectural history?

Recently, the demand regarding reliability and safety of the railroad are increased as built to high-speed railway and Driverless LRT systems. Accordingly, effective management of construction projects is being applied, with the introduction and use of PMIS computerized systems. Due to the construction of railways, from the start of PMIS research planning, design, procurement, to construction and commissioning, various expertise is being carefully gathered, and by integrating it into the unified budget ideas and processes, rational, efficient, organized, and manageable financial plans are developed for the computerized system. However, the current PMIS does not take into account the life-cycle. Therefore, this study is to bring attention to the BIM smart BOM-based configuration management for life-cycle through the consideration for railway construction project management.
