The aim of this study is to suggest an improvement of BTL in Educational Facilities applying the concept of n-BPPP(non-Benefits Public-Private Partnerships). The research is based on four of ninety-nine completed projects of Mixed-use Educational Facilities since 2001. Ninety-nine projects are analyzed and categorized to the typology of architectural program. The architectural programs planned are uniform in function, such as gym, swimming pool, library, info-center, parking etc. The public parking is a main program in the BTL projects, where district offices are involved as partner. The difference between BTL and n-BPPP for educational facilities is the business units. The n-BPPP concerns in regional or district units in order to expand public infrastructure facilities based on the network of schools and local community. And the fund for n-BPPP does not come from the government but from the investors. The economic interest is to reinvest on the maintenance of the facilities. The benefits of n-BPPP will be not only for the Governments in terms of social welfare budgets but also for local residents and students in terms of a variety of high-quality public services. The concept of n-BPPP can be an alternative way for the Mixed-use Educational Facilities.

There has been more increased the development of 3D technique since many 3D contents of 3D graphic model, 3D mobile/computer game, and 3D CAD have been serviced in Web or industry fields. Therefore, the watermarking system is more required to protect the copyright for 3D contents. Currently there has been researched about the watermarking for 3D graphic model of mesh or NURBS. However, watermarking technique based on CAD design drawing leaves something to be desired yet. This paper proposed the watermarking technique for 3D CAD design drawing using Line and Arc components. After drawing out Line and Arc components from designed drawing, we embed the watermark into both the length of Line component and the radius of Arc component. Experimental results verified that the proposed algorithm satisfies the transparency about watermarked drawing and also has the robustness against several attacks by using public CAD tool.

This study suggests that experts' group decision support system (Experts'GDSS) should be helpful to solve specific planning/design problems. Dealing with AHP (Analytic Hierarchical Process), as a group decision model, maximal covering model, as a facility allocation model, and GIS (Geographic Information System; ARC/INFO in this study), as a spatial representation model, this study seeks to examine the implication of GDSS (Group Decision Support System) in the housing facility allocation. The results of this study clearly demonstrated that experts' GDSS acted its positive role, systematically providing the relative weights among the planning variables and objectives. Among different expert groups (e.g., planners, scholars, and public administrators), this study showed that there were certain differences in their decision structures, which generated different solutions in facility allocation. The further study, however, remains to investigate the more systematic implementation of GDSS in planning problems; for example, reducing the conflicts between different groups with different purposes.
