    In this study, we studied the effects of height regulations, height limit(within 20m) and H/D rule (within one), in the case of Shirakabe historic preservation district. Four types of the lot model and 15 types of the building model are examined. As a result, (1) feasible floor volume is not influenced by the height limit because of the ‘shadow regulation’, (2) The height rule reduces feasible building space according to the lot size, e.g. 900 square meters lot causes 10% reduction, (3) H/D rule is effective to preserve the streetscape, but reduces 10% of the feasible floor volume.

    This paper is the investigation and the analysis about the rate of recognizable places in prefectures and typical symbolic elements that are associated with each prefecture.
    The rate of recognizable places is high at both the northern and southern ends of Honshu, both the northern and southern ends of Kyushu, and the prefecture which has two big cities or the largest city.
    And the rate is low at prefectures without symbolic elements, especially at North Kanto, and the part of the prefecture in side of the Sea of Japan.
    And the tendency of the taste is closely connected with “attractive”, “liveliness” and “comfortable”.

    Tackling for global warming at local level is very important. Transnational Municipal Networks (TM’N) centering on environmental issues have contributed to disseminate information for members, and communicate with European Union. In this paper we examine what role the proactive municipalities expect to the TM’N for implementing the low carbon society at local level. The findings of our research are; 1) these six innovative municipalities have proactive policies against global warming and have achieved some positive results. 2) They consider TM’N as information source and the place of discussion, but they do not appreciate direct impact of TM’N on reducing CO2 emission. 3) Having diversified TM’N, the municipalities have possibilities to be a member of them depending on their interests. Diversified TM’N stimulate that each municipality can design his original low carbon society improving quality of life.

    This paper aims at clarifying the actual condition of builders’ acts for seismic retrofit of detached houses. For data collection, questionnaire survey into builders was exploited. The following results are obtained;
    1) Motivated builders to deal with detached housing seismic retrofit are about twice number of the experienced builders.
    2) Builders hardly have initiative to promote the seismic retrofit. Without home owners’ needs, builders hesitate about recommending for home owners to think of seismic retrofit.
    3) Builders expect the government to support for promoting seismic retrofit, such as expanding subsidy and enlightening home owner.

    I discovered a historical document related to Uhei IKEGAMI in “Kaga-Han Odaiku Watanabe-Ke Monjyo (The Watanabe family’s documents)”
    The origin that the document was written is clear, and it is highly reliable by checking with the other historical documents. It is one of a few valuable historical documents pertaining to carpenters in the early period of Kaga-Han.
    As for the time when Uhei IKEGAMI drew “Tenshu-Sashizu”, until now it had been supposed that it was before the end of Kanbun Era (1673), but this document indicates that it was possibly after the 4th year of Enpo (1676).

    Ormuz was a strategic point on the trade routes between the Persian Gulf and the Indian Ocean. There remains a Portuguese fortress in Ormuz Island, which Portuguese used as their stronghold between 1515 and 1622, when they advanced to Asia. Although this fortress played a historically important role, the availability of related literature is quite limited. In this article, based upon a consideration through survey results and collected documents, the author reports that the facilities which were conventionally regarded as a church and barracks must have been a cistern and caravan sarays, and that the defense systems pointed toward the direction opposite to the usual one.

    There are many historical churches in northern Vietnam. They were built according to the traditional technique prevalent in the region. Many of them have become dilapidated and need to be restored, recently. In Xu Phat Diem, some late 19th century timber-framed churches are currently being restored. However, there appears to be some problems with regard to the method of restoration used; these problems are caused by the traditional practices followed by the Vietnamese construction industry. Therefore, we report the current situation with regard to the restoration of the Phát Ngoại church as an example, and then concentrate on the problems.

    Most Japanese conservation areas have their own preservation standard to control selfish refurbishment and new construction. In countryside there is not appropriate guideline for preservation standard such as design code of city center. We research two farm villages that are prepared to designate to the conservation area. Most traditional farm houses have original thatched main roof and were extended or refurbished their eaves to get conveniences for dwelling. If the facade of new eaves match well to the traditional site, this way is suitable to the guideline. We guess this new guideline will be applicable to the other areas.

    Recently, the use of sensor technology in the architecture discipline has been studied in various researches, but generally their instruments of the system aren’t spread. This is because of high cost of the systems, limited web service that can do comprehensive data management, and insufficient cooperation between CAD and these systems.
    For these issues, we can construct the Architectural Monitoring System, by using “Arduino” as hardware for sensing, “Pachube” as the tool of data management, and “Google Sketchup” as linkage system. This thesis has shown the system from getting data to visualizing, using these new ICT equipments.

In the classes, first the videos were shown that represent real buildings oscillated by E-Defense shaking table. That process was followed by practical tests on the structural members related to the videos. As rotating nuts of PC bars, students experienced the load level and the deformation level. According to the questionnaires to such students, they got impressed and felt familiar with structural materials by physically participating in the related tests. Finally, they obtained chances to think the significance of communication with structural designers.

    In recent years, there are a large number of real problems regarding learning structural mechanics at the University. The contributing factors are the decline in academic ability and the fact that many students do not have basic academic abilities for physics and math. To deal with this situation, a self-instructional e-learning system is needed.
    First, understanding the level of students and the type of error were analyzed. Next, an e-learning system for structural mechanics was developed based on the result of this analysis. An experiment for e-Learning system performance was carried out.
    As a result, this system is assessable as a new learning structural mechanics by self-instruction.

In the wooden model, rubber cords and magnets are installed not only for tying beams and columns, but giving restoring force and stiffness to the structure and keeping configuration of each part. In the liquefaction model, flushing system with a small pump demonstrates simplified liquefaction. Thanks to the portability as well as easy repeatable experiments of collapse and liquefaction arriving to inelastic ranges, these are useful for education of earthquake disaster mitigation.
