AIJ guideline against accidental actions is published as a book, "Introduction to shock-resistant design of buildings". This contains respect to objective and scope, design loads, member design, design criteria, non-structural element, progressive collapse and design examples. The objective of AIJ guideline is to minimize human and property damage in building structures against accidental actions based on the performance-based design. Target buildings for design are offices, apartments, hotels, hospitals, schools and public buildings. Structural systems of the buildings are limited to reinforced concrete and steel frame structures. In this paper, the overview of the AIJ guideline is introduced.

We describe the overvier of the J-PARC timing system. J-PARC accelerators consists of the linac, the RCS and the MR, which have different repetition rates. The beam destinations of the linac and RCS are different in each pulse. We present the precise timing system which governs the accelerator timing.

We have collected more than 7,000 deciduous teeth that spontaneously drop out in the process of being replaced by permanent teeth for more than 10 years after the Fukushima Daiichi Nuclear Power Plant accident from all over Japan, mainly from Fukushima Prefecture, and have investigated whether the amount of radioactive materials in dentition formed after the nuclear accident is increased compared to teeth formed before the accident, using Imaging plates have been used to investigate whether the amount of radioactive materials in the dentition formed after the nuclear accident increased compared to teeth formed before the accident. Comparison of teeth formed before and after the accident suggested that even if radionuclides were taken into the body after the accident, they did not significantly increase the amount of radionuclides in the teeth.
