−i−Highlights of the Papers in Synthesiology Volume 9 Issue 2 (Japanese version May. 2016)Synthesiology is a journal that describes the objectives and social value of research activities that attempt to utilize the results in society, the specific scenarios and research procedures, and the process of synthesis and integration of elemental technologies. To allow the readers to see the value of the papers in a glance, the highlights of the papers characteristic to Synthesiology are extracted and presented by the Editorial Board.Synthesiology Editorial BoardDevelopment and utilization of geochemical reference materials— Reliability improvement in the analysis of geological materials — Takashi OKAIThis paper is a presentation of the history and the research scenario for providing more than 50 highly reliable geochemical reference materials over 50 years. The scenario was revised frequently and new research plans were created as the researchers looked at the changes in R&D and the ways in which reference materials are used, the changes in reference materials themselves due to the advancement of analysis devices, as well as changes in the world trends. Here, we can read the history in which the Geological Survey of Japan with its strengths has been leading the world in both the development and research of reference materials.Three-dimensional urban geological map— New style of geoinformation in an urban area — Tsutomu NAKAZAWA et al.This is a summary of the research result regarding a 3D geological ground map that was created for the purpose of utilizing geoinformation in hazard map compilation and urban planning to prevent and mitigate earthquake disasters. The display and modeling of a 3D geological ground map in the heavily populated urban areas have reached a very fine level, and future advancement is greatly expected. Also, multiple elemental technologies including the data collected by local governments are integrated to construct a framework that is useful and easy to use for society. It is a challenging topic that has potential to make contribution to society.Constructing a system to explore shallow velocity structures using a miniature microtremor array— Accumulating and utilizing large microtremor datasets — Ikuo CHO et al.Looking at the shallow ground where damages by strong motion and liquefaction are expected in an earthquake, this paper presents the technological development of a microtremor array that allows accurate exploration of the subsurface S wave velocity structure. This is an example of R&D in which the core technology, on which one of the authors have engaged in R&D over a long period of time and realized an array exploration method, underwent mutual complementation and strengthening through theoretical consideration and technological innovations and the timely response was made to the social demand to know the shakiness of the ground. It should be noted that the ripple effect on the general users is enormous.Development of rock deformation techniques under high-pressure and high-temperature conditions— Evaluation of long-term geological processes by a compressed timescale process model — Koji MASUDABy developing experimental technology and methods to reproduce past geological phenomena that occurred in deep underground in a laboratory setting and to accelerate rock deformation and fracture phenomena that progress in a thousand-year scale, an attempt was made to fulfill a social demand for a highly accurate earthquake forecasting model. The experimental apparatus was developed originally by introducing and integrating high-pressure and high-temperature technologies to a general pressure testing device. This is an excellent example where the research advanced by appropriately setting a research scenario that clearly defines the position and objective of the basic research.Electronic journalURL J-Stagehttp://www.aist.go.jp/aist_e/research_results/publications/synthesiology_e/ https://www.jstage.jst.go.jp/browse/syntheng
