This work proposes a process to derive elements of emotional materials based on trend research in the application of materials in product development. It was intended to be applied to the development of a case model, a Korean sports wheelchair, and focused on the material portion of CMF-based research. Through research methodologies such as megatrends, competitor product and part-by-part analysis, and psychological color analysis, we studied optimization, verification, and DBization of materials, and drew the final application plan through FGI verification.

This study focus on the suggestion of application manual using assembling reference plane design & standard finish material basis upon material classification code. We see it will function as a tool of a linkage between building design and construction standarization in order to enlarge the applicability of house building material that is produced by the module plan. For a estabilishing of this condition, it is neccessary to link the standardization's result of material--design--construction field. According to this neccessity, we are going to suggest information factor that can make relative business manager easily approach to the standardization practical task.

The purpose of this study is to explore the possibility of estimating optimum surface finish time of the fresh concrete placed at the job site by applying a surface hardness test meter(Durometer). Tests are carried out by measuring and comparing the Penetration resistance test and hardness test by Durometer. Penetration resistance tester and improved Durometer are similar, but the higher the temperature, the higher the setting time, and the higher the correlation was shown. When the hardness value of the improved Durometer is about 50 HD, it is found that the initial and 80 HD represent the end. It is expected that this will be useful in determining the finish time of the surface at the actual site.

Various types of robots are being utilized in the construction industry. Particularly, there is high interest in robots that can be applied to plastering automation, which can ensure consistent work quality. In this paper, we propose a robot platform based on wheels for plastering automation. Through experiments, we measured the surface pressure according to the air pressure of the wheel using the designed robot. As a result, we were able to confirm that the designed robot could perform plastering work on soft mortar with uniformly low pressure per wheel.
