This study attempted to analyze the characteristics of interior design of the apartment units of Model-houses in terms of ecological aspects. 9 companies that possessed their model houses among the construction companies in Busan area as of August 2006 were selected. 20 units in the model houses of these companies were visited and analyzed. Through literature review, the guideline for the environmentally-friendly residential design was designed and developed to the checklists. The data collected were analyzed to find out the ecological characteristics of the interior space of apartment units. The findings are the followings. First, energy efficiency was properly considered in terms of natural lighting and natural ventilation. Second, in sustainability, the materials for floors and walls could not be reused even though they were environmentally-friendly. Water system needs more improvement for sustainable development including grey-water and rain recycling system. Third, interior greening should be applied more for better environment both physically and emotionally. It is expected that future housing will be more high-risen and densely-populated apartment spaces. Therefore, an approach to new ecological aspects including an emphasis on interior greening, use of eco-materials and adhesives, water recycling and flexibility of the spatial configuration should be made for the next generation.

Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.

In Korea, a movement for founding a intentional community village is becoming popular to improve the individualistic living environment, and to create a humanistic lifestyle. However, it is difficult to say whether its management is successful or not because the intentional community village such as an eco-village is still in an experimental stage in Korea. In this study, a intentional community village was proposed as an alternative approach to help residents build an effective cooperation system and to encourage them to participate in various communal activities. Detailed cases were studied including a formation process and methods of residents' participation. Through the case study, actual conditions of the community villages and several problems were studied. The conclusion of this study is as follows; In order to sustain the community village, it is crucial to encourage the community spirit among the residents. We also find that developing various community facilities and programs can easily raise a sense of familial warmth among the residents. Above all, proactive participation in the communal activities is the most important. It is also necessary to consider the architectural design which can be used as a guiding principle for foundation of the intentional community village. In addition, concrete and systematic solutions including communal activity programs, residents education, and self management regulations must be discussed.

Recently, there is a big issue of downsizing on brake system according to fuel efficiency and regenerative braking cooperation control. Especially, small cars have improved in a variety ways such as electric vehicle and smart car compared to previous small cars. So, small brake system is strongly required in the car industry. A new small brake system for light compact vehicles was proposed in this paper. For this system, the solid type disc and caliper were newly developed. And the important design factors were considered to reduce brake size. First, we calculated the temperature rise of disc through heat capacity formula and CAE analysis. Second, we analyzed the housing and carrier stiffness of caliper to select the reasonable condition. Finally, the superiorities of the developed brake system were verified by heat capacity, consumption liquid level, braking feeling, judder, wear test and regenerative braking cooperation control analysis. A developed brake system is expected to be useful for brake system of light compact platform.

To receive financial support for the Green Remodeling, applicants must submit an energy simulation report. However, many of the applicants are not green remodeling specialist and energy simulation services are too expensive for them. For this reason, this study was to develop an energy simulation program to enhance green remodeling for the non-specialist such as housewives. Firstly, to enhance understanding and accessibility improvement energy simulation, simulation process was designed four steps and reducing input data. Specifically, input data was reduced by categorizing the following for the area, plan type, hot water load, electricity load, statistical inference. And then, to accurately verify the calculation result, the heat and hot water demand were derived and compared with ECO2 and Energy # program. Lastly, the calculation shows that there is a difference of 4% for the heat load and 15% to 33% for the hot water load respectively.

Recently, eco-friendly electric motorcycles have been considered to replace aging gasoline motorcycles to reduce the amount of suspended fine dust in air. However, existing rechargeable battery-powered electric motorcycles have been found unacceptable by users because of their many limitations, such as long charging time, short travel distance per charge, and low driving speed. To overcome the drawbacks of conventional electric motorcycles, this paper proposes an exchangeable battery-powered electric motorcycle and a new frame shape for housing the exchangeable battery. The proposed frame is similar to that of current electric motorcycles; however, the shape and position of the saddle support, battery, and controller mount section are redesigned. The safety of the presented frame is verified through static and dynamic analyses using ABAQUS. In particular, the dynamic analysis is conducted under the most extreme condition among the various operating situations, thus confirming the robustness of the proposed frame design.

Recently, the wooden structure has been revived again as an eco-friendly structure technique. It is the counterattack of the wood material, which has become more recognized as a finishing material pushed by the concrete material in the rapid growth after the Industrial Revolution. However, it is difficult to conclude that this is a tendency of the construction market in the whole country. Perhaps this is a tendency to appear more strongly in Korea. It could be seen by comparing the characteristics of the overseas construction market with Korean's and the advanced constructed case of large-scale wooden structures in overseas. National wooden buildings show own characteristics such as construction methods, materials, and member dimensions of wood structures by country, which could be seen as a result of continuously developing their own technology. However, in Korea, despite its unique wooden structure and technology (Hanok; Korean traditional housing), it has not been developed continuously and treated it only as a living building exhibit. This is evidenced by the fact that only one percent of the building is constructed with traditional wooden building technology. Therefore, there are various efforts to modernize the traditional wooden structure technology, but it still does not reach the level of advanced wooden technology abroad. The characteristics of the Korean wooden building market were analyzed in order to suggest ways to develop the Korean wood structure technology. The characteristics of Hanok construction were analyzed through quantitative criteria to define the main development tasks for Hanok development to propose the long-term development path.

As environmental issues have been increased globally, eco-friendliness in the construction area, which accounts for more than 30% of total GHG gas emission has being urged. In response, the Korean government has implemented G-SEED(Green Standard for Energy and Environmental Design) certification from 2002. However, total number of certified apartment buildings is only around 1% of total number of approved apartment buildings. As a basic research to find out reasons of low rate of the certification, this paper analyzes consumers' decision-making process in G-SEED certified apartment building market comparing to non G-SEED certified one and draw System Dynamics modeling based on causal relationship. As a result, consumers' demand for the certified one is increased by 'Perceived Relative Utility' which is resulted from comparison process with non-certified one. The 'Perceived Relative Utility' is ascended upward steadily by 'Relative Perceived Price' considered as relatively short-term effect and 'Favorable Image of Certified Housing' referred to long-term effect.

In this study, 10 species of plants with high adaptability to aquatic environments were compared for selecting plant species suitable for vegetation-based low impact development (LID) facilities. The flooding tolerances of the plants were tested by analyzing their growth status under half-immersion and full-immersion conditions, with varying durations of immersion. In decreasing order of flooding tolerance, the comparative analysis of plant height and leaf width is as follows: Hemerocallis fulva, Juncus effusus var. decipiens, Iris pseudoacorus, Phragmites communis TRIN, Typha orientalis C.Presl, Aster koraiensis Nakai, Iris sanguinea, Equisetum hyemale, Acorus calamus. Specifically, Hemerocallis fulva, Juncus effusus var. decipiens. Iris pseudoacorus showed excellent growth status under both immersion conditions. Iris sanguinea and Equisetum hyemale. withered to death by around day 27 of the experiment, but their flooding tolerance was confirmed to be relatively high. Iris pseudoacoru showed flooding tolerance under the half-immersion condition unlike under the full-immersion condition, when compared on day 21 of the experiment. Aster koraiensis Nakai also thrived better under the half-immersion condition, proving to be a highly immersion-resistant species. On the basis of the results of this experiment, Hemerocallis fulva, Juncus effusus var. decipiens and Iris pseudoacorus, Typha orientalis C.Presl were selected as species suitable for vegetation-based LID facilities.
