Since J-PARC started operation for user programs with high-intensity pulsed neutron beams, many material and life science studies have been carried out at J-PARC. Since partial or complete deuteration of organic compounds for contrast variation in the scattering length densities of materials is one of the most effective techniques in the application of neutron scattering analysis, deuterated materials have led to significant progress in our understanding of the structure of novel organic materials. Aiming at accelerating development of deuteration activities in our country, an international workshop "Deuterated Materials Enhancing Neutron Science for Structure Function Applications" was held as a J-PARC Workshop at Ibaraki Quantum Beam Research Center from 19th October to 20th October in 2017. In this workshop, the chemical/biological deuteration activities and recent scientific results of deuterated materials enhancing neutron study in Japan and other countries were discussed by domestic/foreign deuteration and neutron scientists. This is a report of the workshop summarized by organizers.

The objective of this study is to prove the long-term geoscientific stability of the geological environment. The survey will clarify the extent and degree of mechanical change influenced by fault movement deep underground as well as the surface. The study was conducted in Mozumi of the Kamioka mining district, located in the Atotsu active fault system zone. This year, a study was carried out by measuring stress state and rock properties around the active fault. At first, stress measurement by double fracturing was conducted at Nagato No.1 borehole in order to compare a newly measured stress state with the one done last year. The difference between them was very little. Secondly, the first stress measurement was carried out on the Nagato No.3 borehole.
