This research focuses primarily on the feasibility of applying bryophyte to man-made structures in modern urban environment. The study is based both on the role of bryophyte known in the process of the naturalization that life has come on the land and the physiological and ecological characteristics of bryophyte. The primary characteristics of this species lie in its desiccation-tolerance and poikilohydry that supports its enduring survival even under the desperate environmental conditions. The monitoring of applying bryophyte to man-made structures has shown us that bryophyte could control microclimate conditions, help to mitigate flood by reducing runoff, and lessen thermal conductivity, etc. The application of bryophyte to man-made structures has just started since 2002. Even though efforts to use bryophyte in greening man-made structures in Japan and Korea have resulted in both successes and failures, it is noticeable that there has been quite much technical progress in using this unique plant species.

Statistical analyses with actual data are used in estimating construction cost for many years, but collected data could include factors that distort analytical results, namely outliers. To enhance reliability in predicting construction cost, the methodology, which is able to identify outliers and determine how to manage them, is needed. Actual costs obtained from 22 construction projects were studied. It is found that there is substantial disparity between results considering outliers and results not considering ones. Therefore, it is to identify outliers and apply an optimum process in estimating construction cost when actual data is used in statistical analysis.

The purpose of this study is to suggest the model of rural villages for 21th century guidance-style based on regional Indigenous resources. As a development model on premise environmental sustainability, economic sustainability, social-cultural sustainability, this paper aims to established that accommodate actively change element of village environment that stabilizes local environment and ecosystem on the basis of development model's principle and contents and information area. Through this model development, To makes the national setting an example village and plans the 21th century guidance style farm village continuously is big that study does.

Being different from 20th Century, the right of disabled have attracted much social attention. In reality, the disabled still suffered or not properly respected, thereby a little far less in achieving the quality of life. The purpose of this research was to examine the fitness between the persons with limited mobility and their living environment. Small group workshop with three persons with limited mobility were used for utilized. Living behavior and physical environmental characteristic of dormitory house and interaction between them were identified. Major problem appeared to be accessibility which include the path, room size and furnishing. Even though the dormitory satisfied the government requirement legally. Substantial problems were found because of resident real life. This implied deep consideration beyond Act needed to create a right to robust environment toward persons with limited mobility.

Most of current building materials are made of organic compounds or at least made with chemical treatments. Though easy to use and comparatively pay less, those materials are generally not enviornmentally sound. VOC is one of harmful effects. On contrary, natural materials such as soil are usually eco-friendly, and environmentally sustainable as well if not treated in autoclaves. Acoustica materials made of such environmentally sound and sustainable could be widely used. It is aimed to prove that soil based materials could be effectively used in acoustical fields rather than the other usual materials. Experiments with various types of soil blocks and soil plaster were performed. It is proved that the soil plaster has better apsorption features than cement plaster. Soil blocks have higher absorption cofficients than soil plaster, due to the thickness, and the absorption characteristics can be controlled by the design of the blocks.

It is known that early reflections, their energy and delay times after the arrival of direct sound are important factors for speech intelligibility. In this basis, acoustical parameters like D50 and C80 had been proposed and are widely used for assessing the listening condition of rooms. These parameters are focused on the fraction of the early energy to the total, regardless of the spatial characteristics of the early reflections. This means that all the early reflections, arrived in certain time boundary. from front, behind, down and upside have the same impact on speech intelligibility. From the questionable simplicity, the influence of the direction of early reflections on speech intelligibility is examined in this study. A computer simulation speech intelligibility test, conducted for 22 university students, found that the reflection of vertical direction with method of the Paired comparison also the preference of 0.746 degree was visible an increase.

The starting point of successful building production process is the feasibility study of the project. If the feasibility study is poor which is affected in direct production processes such as designing and engineering, it incurs a great unrecoverable loss to the company. The government institutionalized the feasibility study for projects that budgets over 50billion won in an effort to ensure competitiveness of the construction industry after IMF; however, the system and effort to created systematic studies or guidance preparation for private construction development projects are lacking in great deal. Therefore, the objective of this study is to establish the analysis factors of feasibility study and evaluation standard by systematic analysis in consideration of the changes of various variables and mutual relationships using system dynamics technique for office buildings among commercial buildings.

As of August 2005, there are 9,007 facilities for public primary, middle and high schools in Korea. But because of depopulation, hereafter it is expected to allocate much more budget and interest to utilizing the existing facilities reasonably rather than new buildings construction. At present the maintenance of educational facilities is depend on not a preventive but a post preservation. And there is no established maintenance organization and system, which causes both facility deterioration and squandering of the nation's resources. Thus the object of this paper is to examine a maintenance system of established public school facilities and to improve the system which is enable to maximize the efficiency for the existing maintenance organization.

The purpose of this experimental study is to investigate the compressive strength, shear strength, bending strength, and crack control by the mixture of the hwang-toh. The size of compressive specimens is $200{\times}200{\times}400(mm)$, and the size of shear, bending specimens is $200{\times}200{\times}600(mm)$. Finally, crack control specimens for comparative comparison is $200{\times}200{\times}15(mm)$. The mixture of the hwang-toh is as follows; Hwangtoh( H)+Water(W), H+W+Sand(S), H+W+S+sTraw(0.5%), H+W+S+sT(1.0%). The actual height, width, and the length are measured at the center of all specimens. The main parameters are mixture ratio of hwang-toh, straw and age of specimens. The test results are as follows. (1) The compressive strength is linearly increased until 15 weeks according to specimen ages. (2) About crack control, the specimen added in 1% straw is the most effective.
