Fast industrialization caused from Descartes' dichotomy has enormously developed our world, but endangered the ecosystem. In this study, the ecosystem aesthetics is not only a critique against existing growth-ideology and technical civilization, but also the art pursuing the life as an artistic state and achieving the dream for qualitatively different new future. Lao-tzu's Natural Beauty assumes that the adaptation to natural laws can lead every purpose's achievement. Based on such theoretical alternative, the earth construction as a medium for coexisting mankind, nature and construction interacts with the other objects through the natural affinity, the energy efficiency, the material generation. The earth construction provides the images of naivety, naturalness, folk as well as emotional stability in cultural terms. This study's direction and method are as follows. First, it researches the ecosystem aesthetics from the Taoism viewpoint, the alternative for environmental healing based on theoretical reviews about the ecosystem aesthetics. Second, it researches the earth construction's ecosystem aesthetic features and construction features from the low-tech aspect in continual construction genealogy. Third, it analyzes some cases targeting domestic buildings by drawing out expression methods and features through the connectivity of earth construction and ecosystem aesthetics. The earth construction lies between the heaven and the earth, but coexists in natural cycle. The earth construction caused from ecosystem aesthetics will be a future alterative, and various studies about its features and methods should be continued.

Formwork accounts for 10% of the total construction cost and 30~40% of the framework cost, which is a fairly large part. Various system forms were developed for improved economic feasibility and constructability of formwork and for reduced construction duration. In general, the price of system forms per unit area is higher than that of the conventional method, yet the total construction cost can be reduced through higher reusability and constructability. However, if the reusability of forms is excessively increased to cut down the material cost, it may increase the construction duration, which will result in cost increase. On the other hand, if the reusability is decreased for reduction of construction duration, it may lead to cost increase caused by excessive input of materials. To solve such a problem, an algorithm for simplified reuse planning that meets the requirements of construction duration, cost, quality and safety is required. In this regard, the study intends to perform a fundamental research for development of reuse planning automation algorithms on system forms that are used on girders and beams.

The major countries including Korea extend the national investment on R&D and implement the business performance diffusion policy as the knowledge based competition age arrives recently. The necessity for risk management and systematic management system for R&D achievement have been appeared to prevent the failure as the R&D scale becomes larger as it was said. For this matter, the organization such as NASA and DoD in USA defines the Technology Readiness Level (TRL) as a quantitative accomplishment management index and utilize the Technology Readiness Assessment (TRA) system as a criterion. Such tool is evaluated as very effective in the R&D project purposed the practicalization. It is expected that the disadvantage of evaluation system which is oriented to the academic accomplishment in its contents of current research and to contribute greatly to the practicalization of outcomes when such technology readiness level concept is applied to Korean national construction and transportation R&D project. Accordingly, this study analyzed the concept of TRL·TRA, the characteristics and current evaluation management system of Korean national construction and transportation R&D project and suggested the construction and transportation R&D project TRL·TRA performance model to accomplish the practicalization purpose.

Today, The representation of the modern space is experimented with shape and surface of the de-structural point of view to make architecture and space, in terms of not being able to make defined by single regulation. However, it can correspond to the rapidly changing modern, but it is easy to fade of architecture fundamental meaning. Along with the need for the rise of the construction of fundamental space, should be built a 'tectonic' spatial, which is said to be building of logos. Tectonic, as norms for expressing the fundamental meaning of architecture, as to expression of construction, be unfolded with dualism such as science and art, technology and express, structure and formation, and it was introduced into the architecture through the construction expression of space that was a tectonic discussion of 19c german architects. On the other hand Constructivism which is avant-garde formative movement with Russia revolution, constructed 'sculpture' with the formative principles as tectonic. Tectonic's Formative characteristics can draw a conclusion with of tectonic characteristics of constructivism sculpture, space of logos will be realized through its study. Other hand, The pavilion, as symbol space, can be analyzed by tectonic properties, Pavilion, meaning the space is expressed in a variety of tectonic expression. As tectonic construction, fundamental ideology and symbolization of space is revealed metaphorically and visually.

Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

BAT 공장 건설 프로젝트는 외국 발주자에게 한국 CM업체의 관리능력을 입증한 대표적인 프로젝트라고 한 수 있다. 본 프로젝트는 CM 사의 전문적인 관리를 통하여 외국의 공장건설에 비하여 $15\%$ 절감된 금액으로 공사를 완공할 수 있었으며, 철저한 공정관리로 공기를 단축하는 한편 준공 후 1개월도 안되어 생산이 이루어지는 성공적인 결과를 달성할 수 있었다. 본 프로젝트의 성공요인(Key Success Factors)은 CM사의 탁월한 관리능력이라고 할 수 있으나 더욱 중요한 성공요인은 사업관리의 모든 권한을 CM사에 위임하는 발주자의 신뢰에서 기인되었다고 할 수 있다. 본 연구는 "One Stop Shop" 개념의 CM 적용을 통하여 사업의 전단계에 걸친 전문적인 관리활동과 발주자와 CM사간의 신뢰의 중요성을 입증한 프로젝트에 적용된 Cost Management, Contract Management, Value Engineering 등의 활동을 고찰하였다. 본 연구를 통하여 민간시장의 CM활성화에 비하여 적용에 어려움을 주고 있는 공공시장에도 CM이 활성화 될 수 있는 계기를 되기를 바란다.
