STAVi is the personal mobility vehicle that has some useful functions for handicapped persons. Therefore it will be effective to support a handicapped student in schools. However, it is a prototype machine whose is not assumed to use at school, so it is necessary to improve the mechanism and function. In this study, as the ﬁrst step of universalizing educational environment using STAVi, the situation where STAVi was used was conﬁrmed by the fabricated simulator and actual running test. As the second step, the speed change system that is according to the distance to the object and the presence or absence of a difference in level was made using an ultrasonic sensor, infrared sensors and an Arduino Leonardo. The collision of the STAVi and pedestrians or going off the shoulder of the road is avoided by this method. As a result, the safety of STAVi was enhanced.

As the result of research on three different types of housing units and complex in Yatsushiro city, the requirements are as follows. 1）An intermediate space between closed and opened, such as a garden space faced to public road of housing complex is effective.
2）To make“lived-in feel”in housing complex, a space in perimeter around housing unit to permit resident’s goods such as a planter is necessary.
Though emergency drills should be executed to conceive several conditions, it only gets executed in a single evacuation route.
In order to cover this shortcoming, this study make an evaluation on emergency drills by using a pedestrian simulation software, and suggest more better methods of drills. As the result of simulation of the action of drill of Yatsushiro Campus, conclusions are as follows.
1) The result of simulation is quite similar to practical actions of pedestrians, so that the software“SimTread”is useful for predicting the actions.
2) By using“SimTread”, we could ﬁnd the evacuation method at a much faster time than at present.
The report examines process and problem of making of architectural models with two types of 3D printers. As a result of modeling, it is clear that 3D printer can output architectural details more correctly as opposed to conventional handmade models.
This paper reports three temples connected deeply with the lord of the Yatsushiro Castle. There are Annyo-ji temple, Honjyo- ji temple and Syunko-ji temple.
Annyo-ji temple is the most luxurious among three temples, because it was built in the early 17th century. In addition, the module is the biggest too. There are splendor and formality in Honjyo-ji temple’s inside in contrast. The form of plan of Syunko-ji temple resembles chief priest architecture of the Zen Buddhism.
Honjyo-ji temple and Syunko-ji temple were built according to a law. The law was established in 1668 to control the size of temples. Therefore these roofs are shikoro form and these depth is 6ken. Actually, Syunko-ji temple was rebuilt in the Meiji era. However, the reason to have the characteristic of the law is because it was restored in the ﬁgure of the Edo era.
In this investigation, recent climatic change in Japan area is analyzed. The purpose of the present study is to evaluate the recent trends of the average temperatures and other weather records（1983-2012）. The annual average temperatures in most prefectures are rising at a rate of 3-4℃ /100years and they have a certain degree of relationship with the human activities. It is found that the annual average of the daily maximum, the daily mean and the daily minimum temperatures are rising, and the average amount of solar radiation and the sunshine duration are increasing for 30 years. Further, the annual maximum of the hourly rainfall intensity is also increasing. It is possible that the global warming has affected the climate in Japan.
In 2011, the four nuclear reactors at the First Fukushima nuclear power plant were burst and broken by the great disaster, East Japan Earthquake. In this report, we consider the nuclear power supply. The cost of nuclear power generation is not cheaper than the other generation costs, because the cost does not include the uncertain enormous compensation of serious accident or the processing cost of nuclear waste. An opinion in Japan was surveyed by questionnaire from a generation in Japan, students of 3rd year ,in high schools or national college of technologies. Their opinions about the problem, which we should abolish or continue the nuclear power generation in future, were divided in half and half. It is desirable there is much information from electric power companies to young people on the essential problems of the nuclear power generation. The public debate on the nuclear generation in Japan is still required to the future.
