As most of environmental impacts caused by development projects are irrevocable, a thorough review is utmost necessary. Ecological-economic integrated approach inspired by Norgaard's co-evolution theory should be applied to the environmentally adjusted CBA, which plays a decisive role in the feasibility analysis. Based on case studies of NamHan River Management Project and Yeongsangang Wetland Reclamation Project, this paper attempts to show the usefulness of linking basic plan and implimentation design to EIA and suggests to integrate EACBA into the current EIA system institutionally as a more effective policy tool for realizing sustainable development in Korea.

The purpose of this research is to evaluate five types of eco-village planning in order to introduce a landscape unit concept and theory in Korea. Although they had different backgrounds and motives of eco-villages planning, their common goal is to always maintain ecological planning and design in their villages. As concrete methods of ecological planning, we suggest three fundamental planning theories. 1. The boundary of a plan unit should be a watershed. 2. The survey and analysis of village ecotopes should be done in that defined watershed. 3. These results should be applied in the site and lot planning of eco-villages. These 3 steps should be done in a process and relevantly. In the evaluation of the five eco-village planning types, we found three results. 1. On a viewpoint of watershed, most planners recognized a watershed in survey and planning stages unconsciously. But they did not mention watersheds concretely and did not use this concept in the planning stage. 2. They did not define the concept of ecotope, but most planners recognized land-uses and vegetations of villages and vicinities as ecotopes. Also these could be proper ecotopes, but they did not use these compartment of ecotopes in the planning of ecosystem structure in villages. In addition, they did not deeply survey and analyze the ecotopes of villages and its vicinity. 3. On the viewpoint of sites and lots planning, they did not relevantly use the characteristics of watersheds and ecotopes in sites and lots planning. Therefore, they failed to implement the indigenous lots and subdivisions plan. In the size of lots and sites, they did not seriously consider the carrying capacity of ecosystem. We hope that our suggestion about the establishment of eco-villages planning is a fundamental theoretical framework of ecological planning in future eco-village planning.

East Asian explain the changes of substance happened on earth and those of human life with the conceptual frame of "Gi-ki"(地氣; earth vital energy) and organize them by the system of "Feng-shui(風水) theory. The core of Feng-shui theory is reading the expression of the nature and feeling the Gi-ki from the expression. One of the properties of the earth is that the earth has a magnetic field associated with it- the Geomagnetic field. The geomagnetic field is produced by a combination of the effects of electric currents in the earth's liquid core, the magnetization of crustal rocks, external electric current systems that surround the earth and currents induced in the outer layers of the earth by magnetic field variations. The sameness of logic between Feng-shui and geopathic zones is that both are concerned with the discrimination of site and the energy of places, in other words both disciplines are concerned with how the environment can influence people. In this context the operation of Gj-ki can be related with the effect caused by geomagnetic field on site. In this study Jongmyo(宗廟), one of the representative traditional architecture in Korea is selected because the site selection and building layout follows Feng-shui faithfully according to Taejo silok (太祖實錄, Annals of King Taejo). Observing the landforms surrounding Jongmyo, Jongmyo is apparently located in auspicious places named Gumge Poranhyoeng(金鷄抱卵形, a Feng-shui landscape of golden hen sitting on eggs). The geomagnetic investigation of Jongmyo shows that the geomagnetic values of Toekan(the space near Hyeol) are relatively high and uniform and those of Sangweoldae and Haweoldae are decreased in accordance with the distance. The result shows that there is possibility that Feng-shui has scientific basis related with geomagnetic field. Feng-shui theory can suggest a direction for designing the sustainable building for living with nature.

Modeling and simulation of human-involved complex systems pose challenges to representing human decision makings into logical systems because of the nondeterministic and dynamic nature of human behaviors. In modeling perspectives, human's activities in systems can increase uncertainty and complexity, because he or she can potentially access all other resources within the system and change the system states. To address all of these human involvements in the system, this research suggests applying the Finite State Automata (FSA)-based formal modeling of human-involved systems that incorporates the ecological concept of affordances to an evacuation simulation, so that human behavioral patterns under urgent and dynamic emergency situations can be considered in the real-time simulation. The proposed simulation methodologies were interpreted using the warehouse fire evacuation simulation to clarify the applicability of the proposed methodology. This research is expected to merge system engineering technologies and human factors, and come out to the new predictive modeling methodology for disaster simulations. This research can be applied to a variety of applications such as building layout designs and building access control systems for emergency situations.

Generally, ground-source heat pump (GSHP) systems have a higher performance than conventional air-source systems. However, the major fault of GSHP systems is their expensive boring costs. Therefore, it is important issue that to reduce initial cost and ensure stability of system through accurate prediction of the heat extraction and injection rates of the ground heat exchanger. Conventional analysis methods employed by line source theory are used to predict heat transfer rate between ground heat exchanger and soil. Shape of ground heat exchanger was simplified by equivalent diameter model, but these methods do not accurately reflect the heat transfer characteristics according to the heat exchanger geometry. In this study, a numerical model that combines a user subroutine module that calculates circulation water conditions in the ground heat exchanger and FEFLOW program which can simulate heat/moisture transfer in the soil, is developed. Heat transfer performance was evaluated for 3 different types ground heat exchanger(U-tube, Double U-tube, Coaxial).

The information matter-element system was built to assess safety of water source. Based on the thought of multiindex fusion, fuzzy matter-element model evaluating water source behavior was constructed by matter-element transform. This model can process comprehensively hydrogeological data, ecological environment, water pollution, surface disturbance, and so on. Water source safety behavior can be described by the qualitative and quantitative manners. According to the development trend of quantitative results, water source safety behavior can be expressed dynamically. As an example, the proposed method was used to assess safety status of 7 water sources in the region. The numerical example shows that the proposed method is feasible and effective, and the evaluation results are reasonable.
