This paper presents traditional wooden buildings in the preserved district in Murata Town, Miyagi prefecture. Architectural laws have been revised many times. When considering the damage of the earthquake, seismic retrofitting is necessary, but it is difficult to achieve both a traditional construction method and current laws. In this paper, we consider a method that conforms to the current laws by traditional construction method and report its contents.

This study aimed to propose a porous and lightweight structure using the 3D printing technology. We report on the development of the large scale 3D printer called “ArchiFAB”, and the improvement of extruder technology for realizing low-cost and high-speed 3D printing technology. We performed two compression experiments to verify the mechanical properties of periodic minimal curved surface called “Gyroid”, that were difficult to realize with the conventional construction method. Moreover, we proposed the construction system based on a concrete block construction method using geometric features of Gyroid.

In order to resolve both the problem of poverty and global environment, we should take informal settlements in developing countries as the front-line of learning and find solutions for such global issues. Here we report our design-build education composed of “short term workshop” and “long-stay architectural practice” towards the incremental improvement of an informal settlement in Jakarta, Indonesia.

The architect license system in the United States of America and its recent revisions were investigated. In order to be registered as an architect there, the requirements are defined in the three categories: education, practice and examination. Through the investigation and interviews, trends in the recent revisions are revealed in relation to the 2012 NCARB Practice Analysis of Architecture. As architectural practice expands and evolves in a global context, the portability of professional credentials becomes further more important.

American architect system consists of three independent requirements of (1) Education requirements, (2) Practice requirements, and (3) Examination requirements. In this paper, Intern Development System (IDP) and Architecture Experience Program (AXP) for Architects in America were investigated as part of Practice requirements. Collection of the current data was conducted, and real situation on practice was observed via hearing survey. Analysis was made to reflect the revision for the Practice requirements and clarified how it was operated through facing actual situations. Overall researches are intended to obtain significant knowledge for the upcoming requirement for the quality of Architects in Japan.

This paper demonstrates the resistance to wind damage of tall trees which intends to be decreased by transplants. The objectives of this study are to clarify that how much the resistance to wind damage of the transplanted tall trees is improved by applying some supporting systems to them. At the same time, the safety of the transplanted tall trees against strong winds is discussed. Various useful information was obtained from the results that we had conducted pull-down loading tests of seventeen tall camphor trees.
