Currently, a BIM-based quantity takeoff (QTO) system is mainly focused on architectural projects. To perform this, diverse quantity takeoff methods such as an object-based automatic quantity takeoff, manual quantity and base functions of calculation have widely been utilizing. However, since BIM library for road projects includes structural elements associated with alignment, it is necessary to establish cost estimation system interlocked with historical cost using 3D library by each unit length. Accordingly, the aim of this study is to develop cost estimation model with using a historical cost approach so that it can be utilized in construction planning based on the BIM library for road projects. For this, based on the BIM library for road, the standardized quantity is estimated, and a process for calculating historical cost and a verification model with a 5D simulation was developed by mapping a WBS code with each BIM library object. This can be applied during the approximate cost estimation process in a project planning and an initial design phase for road projects. Besides, it is expected that these results will be utilized in constructing an optimal historical cost estimation process for project libraries.

Urban outdoor playground serves as the space to promote the physical, cognitive, social, creative, emotional and linguistic development of children and the education center to stimulate the imagination and curiosity of them. It is also the place to be used as a basic park for urban residents and the local community space for associating with people of various levels. However, this playground as a banal space did not function properly before now. In 21st century, urban playground requires change and its various changes have been attempted. In particular, there is a need for the change into eco-friendly playground to provide children's health and urban healthy environment. Therefore, it requires much effort to construct and vitalize the eco-friendly playground adequate for domestic circumstances in Korea. This study derived the preferred planning items among eco-friendly playground planning elements focused on the people to use it and provided the data for the construction of local friendly, eco-friendly outdoor playground. For this purpose, we visited the playground of the apartment house built in 10 years with more than 300 households and surveyed 200 adults and investigated the residents' utilization and satisfaction on the current playground and the recognition and preference for eco-friendly playground.

An attempt has been made to prove the so-called 'feature accumulation theory'. It is the theory describing that people tend to feel the same space with more identifiable objects much larger than that with fewer objects. Applying this theory to our cognition of spatial size, this paper made an experiment. Students were asked that if the lecture room they are sitting becomes a module (module 1), then how large are the questioned spaces in the campus. The result was striking. Through the mental image processing, they answered that the library and the architecture building looks much smaller than they actually are, and more surprisingly the basketball field much more smaller than it really is. This experiment shows that there is a strong tendency by which people regard the space much larger when there are more occupiable or behavior-causing elements in the space. In the case of basketball field, since there is nothing that can be occupied, this open space is seen as a small space for the subjects. This line of cognitive perception can be applied to the practice of urban planning and architectural planning. With the same size of given space, we can make it feel more rich and larger.

Real-time mobile robot controllers usually have been designed with an emphasis on control theory ignoring the importance of system integration. This paper demonstrates that useful mobile robots require a real time controller with a wide range of capabilities in addition to control theory. These capabilities include: path-planning, position estimation, path tracking control and wheel control. An architectural framework supporting these capabilities has been designed and implemented. Using this frame work, individual modules such as a path planner, a path tracking controller, position estimators, wheel controllers and other cruical elements have been successfully integrated into the control system for the LCAR robot which was developed as a proto-type mobile robot in our laboratory. The context of the research, the architecture, its implementation and performance results from experiments are discussed.

The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of Museum, and this space imagery is created here by all the space composing elemensts of Museum. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer, could be called as 'the transition' and the changes of the space characteristics as 'the transition characteristics'.
