  15th Korea-Japan Meeting on Neutron Science (January 6-8, Busan, South Korea)
      These Korea-Japan Meetings on Neutron Science began with exchanges between the High-Flux Advanced Neutron Application Reactor (HANARO) of the Korea Atomic Energy Research Institute (KAERI) and the KEK Pulsed Spallation Neutron Source (KENS) of the High Energy Accelerator Research Organization (KEK). These international conferences are held every year, hosted alternately by Japan and Korea, to discuss neutron scattering instruments and research utilizing them. In August 2010, Korea established the Center for Korean J-PARC Users (CKor J-PARC) as an organization within Seoul National University to promote and facilitate experiments using neutrons at J-PARC, and a Memorandum of Collaboration was signed with the J-PARC Center in October 2010.
      At this meeting, there were 45 participants from Korea and 27 participants from Japan, and the meeting on the 7th began with a greeting by Professor Sung-Min Choi of the Korea Advanced Institute of Science (KAIST), acting as representative of the Korean side which hosted this meeting. At the meeting, there were 30 oral presentations and 26 poster presentations. In the oral presentations, researchers from the two countries exchanged information regarding all aspects of neutron experiments, including reports on the situation of joint research results, reports on the MLF, J-RR3 and HANARO neutron experimental facilities, and an overview of research progress over the last year. In the poster presentation segment, Ms. Mariko Isono of Nagoya University received an award for her outstanding poster presentation. At the end of the conference, there was a summary report, and closing remarks by Professor Sungkyun Park of Pusan National University (PNU).
      At the business meeting held on the 7th, it was discussed that every opportunity would be exploited to advance research cooperation between Japan and Korea, and regarding future meetings, it was decided that in 2017 there will only be a business meeting because the ICNS (International Conference on Neutron Scattering) will be held in Korea, and the next research meeting will be held in 2018 in Japan.

  MEXT Elements Strategy Initiative: Collaborative Symposium for Large Research Facilities (Second Symposium, January 21-22, Hongo Campus, University of Tokyo)
      In the Elements Strategy Initiative, which has been promoted by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) since 2012 to encourage the creation of innovative materials, active R&D is being carried out in four material domains (magnets, catalysts/batteries, electronics, and structures) for which research bases have been established. This work is being done through collaboration between large research facilities such as J-PARC's Materials and Life Science Experimental Facility (MLF) and the worldfs largest synchrotron radiation facility (Spring-8), and supercomputer resources such as the K computer. At this conference, participants exchanged information and had lively discussions about previous results, methods of utilizing facilities, the needs of industry, new ideas in academia, solutions to problems and other topics. In connection with J-PARC, there were reports on the recent situation at the MLF, the current state of neutron and muon science, the latest results in those fields, and the results of muon experiments (e.g., the results of a muon experiment to elucidate the origin of the electrical conductivity which appears due to hydrogen injection into cement (C12A7)). Poster presentations included: research on hydrogen in materials using NOVA at MLF and related materials development, sample environment equipment of the "TAKUMI" Engineering Materials Diffractometer, magnet material research using the "iMATERIA" IBARAKI Materials Design Diffractometer, storage battery research with SPICA using neutrons, science using neutrons and muons at the MLF, and elements strategy electronic material research in the MLF muon experiment area.
