    The purpose of this study is to consider a necessary community planning activity and the problem by investigating the content of the situation of the community planning activity for the urban regeneration. The district where the community planning activity for the urban regeneration is executed increases year after year. Moreover, a downtown, a sightseeing spot, and a residential quarter are the majority in the district where the community planning activity is executed. It is important to establish the activity organization for the success in the community planning activity. And it is important to establish the system to continue the community planning activity.

    The possibility of interaction between boundary space and multi-actor partnership was examined through a series of workshops and event planning meetings. Starting from a proposal in university studio course, students acted as coordinator among several actors neighboring the site, eventually led to an establishment of community design organization. In the process of partnership building, design operation was made twice, using small devices and as a site for event venue. The spatial layout was discussed and improved as the number of actors increased. Key findings to promote the interaction between boundary space and multi-actor partnership are: neutrality of coordinator; continuity between each workshop; diversity of the participants; and urban design center as a base of community design.

    We evaluated the effectiveness of a charette for reviving the collaborative planning process by two critetia. Criterion one is “How the charette worked for letting people to think another person’s stance.” and criterion two is “How the charette worked for reviving the collaborative decision-making process.” We had the experimental charette with students, and found that it worked for understanding people’s stance and collaborative decision-making process. It specially worked for compromising with other participants regarding conflict points.

    The aim of this study is introducing a new method in VR environment by using animating textures to represent human activities inside the urban space (Active Virtual Reality Environment “AVR”) to enhance the sense of realism and interaction in VR environment. Furthermore, there is a comparison among three methods in building VR environment by conducting a psychological evaluation for the Three VR methods. To achieve the objectives of research, the following steps have to be taken; developing a system to show the animating textures and using them to show the urban space activities, preparing a prototype system, selecting an appropriate site and building a digital model for it to create and develop a VR System. Finally, we utilized a prototype to build AVR system.

    This practical study is based on the consumer education course of home buying. It is real estate agent’s duty to explain important matters to the buyer. Half the buyer has no memory of the explanation. 70% has no memory of the delivery of the paper. Half does not comprehend the important matters. 90% suspect to commit to a professional if the fee is acceptable. It is useful to instruct basic knowledge, to hold the consumer education course, to establish the advice centre. The transaction system which has the professional attendance to give advice to the consumer is also useful.

    Architects and construction engineers use a wide variety of technical documents including the building codes and their in-house specifications. It is a laborious process, or is almost impossible, to search completely all the relevant documents for their projects. This report proposes a new methodology to retrieve technical documents using an index called the logical inverted file. In this method, a technical document is written as a document tree, the nodes of which have conditions as well as technical contents. The prototype scans a building information model and searches the document nodes of the conditions that the model satisfies.

    This study analyzes the planning process of the scaffolding in the extensive renovations of the high-rise condominiums. As the result of the analysis, the following items were clarified.
    · It is preferable to accept some opinions of the constructors to the scaffolding plan.
    Therefore the planner should devise the method of accepting some opinions of the constructor at the plan stage of the scaffolding plan.
    · Not only the gondola scaffolding but also the prefabricated scaffolding are effective in respect of construction expense.
    These results will be important reference items in the maintenance of the high-rise condominiums.

    This paper reveals the development process of reversing saw based on literary materials and real saws themselves. As a result, the following facts have been found.
    (1) It was found in one of the documents that the kind of reversing saw that is shaped like fine work saw with its head split in two, existed in the region of Tokyo prefecture in 1877 (the tenth year of Meiji) .
    (2) The inspection of the kind of reversing saw that appeared in the early Meiji era revealed that it is characterized by the shorter neck and tang compared to what we currently have, and Tamahagane (jewel steel) is used as a material to make the blade.
    (3) Behind the spread of reversing saw was the generalization of western steel (Togo Steel) as a material for blades and oil hardening technique, and the pursuit of convenience.

    Yokohama Raw Silk Inspection warehouses, completed in 1926 at Kitanaka-dori Yokohama, were designed by Oto Endo, famous as a pioneer to introduce reinforced concrete structure in Japan. The followings were identified by the examination; the warehouses with reinforced concrete have flat slab structure. These buildings had rarely changed to its original appearance and structure. A new technology was introduced to resist an earthquake as well as fire since the buildings were constructed just after Great Kanto Earthquake. Therefore, it can be said that the buildings are surely recognized as an important property on both architectural and technological histories.

    This paper discusses the problems of school’s earthquake disaster reduction activities. A questionnaire survey was carried out among municipal government education boards in Japan. Over 30% of municipal governments indicated that more than a decade was needed or it was unpredictable, to meet seismic code for public elementary/junior high school buildings. In addition, earthquake resistance measures at school facilities have issues especially in earthquake countermeasure implementation area. To improve disaster reduction activities, educating teachers about disaster education as well as better coordination between schools and region residents are also recognized as important.
