−i−Highlights of the Papers in Synthesiology Volume 7 Issue 4 (Japanese version Nov. 2014)Synthesiology is a journal that describes the goals and social values of the research activities where the results will be utilized in society, the specific scenarios and research procedures, and the processes of synthesis and integration of the elemental technologies. To allow the readers to see the values of the papers in a glance, the highlight points of the papers that are particularly in line with the characteristic of Synthesiology were extracted and presented by the Editorial Board.Synthesiology Editorial BoardNew research trends in artifactology Modeling of individuals and socialization technology Ota (Research into Artifacts, Center for Engineering) et al. describes the methodology to establish the research of artifactology. It is interesting that to attain a sustainable, harmonious relationship between artifacts and individual-society-environment, a methodology is developed from the modeling of individuals whose values shift due to the presence of artifacts, and from the achievement of social technology for artifact co-creation that incorporates both the objective identification and solution finding through collaboration among the parties on issues for which the objectives are unclear. The specific examples given are the individual modeling using an experimental economics method and the modeling of a product service system.Mental fatigue measurement as application software on consumer devices Introducing reliable fatigue index to daily life Iwaki (AIST) et al. developed a technology that allows the evaluation of fatigue (flicker test) by measuring the perception threshold of visual “flickering.” This was conventionally used only for academic purposes using special equipment, but this new technology allows the use of general-use electronic devices such as smart phones and personal computers on a daily basis. While the flashing frequency is used in the flicker test, it is shown that the test can be done using the flashing contrast. The elemental technologies for the fatigue monitoring system using the general-use electronic devices and their integration scenario are explained.Development of evaluation technologies for sedimentary characteristics Applicability of the technologies to the assessment of methane hydrate sediments In order to use methane hydrate as a new natural gas resource, accurate prediction of the effect of exploration to the surrounding sedimentary strata is necessary from the perspective of social acceptability as well as economy. This paper by Tenma (AIST) is an overview of the development of a sedimentary deformation simulator for a long-term, safe production, the well integrity evaluation based on the simulation, and the system of wide-area sedimentary deformation evaluation technology that were conducted by the “Methane Hydrate Resource R&D Consortium (MH21).”International standardization of four dimensional radiotherapy system Enhancement of effects of irradiation and assurance of safety In radiotherapy, it is necessary to accurately irradiate the necessary level of therapeutic radiation to the tumor position while avoiding exposure of healthy tissues, although the tumors may move due to patient’s respiration. Hirata (Hokkaido University) et al. created the standard for technological requirements of safety for the four-dimensional radiotherapy system considering the time change of the three-dimensional position of the affected area. The strategy and result of the international standardization that was promoted by a wide range of stakeholders including the Japanese medical device manufacturers, physicians, medical technicians, researchers, related government bureaucracies, and others are described.Preparation of superconducting films by metal organic deposition Research and development towards a fault current limiter and other electric devices By forming into a thin film, the high-temperature oxide superconductor is a hopeful material in the application to various devices and equipment, as well as use in the transmission lines. Manabe (AIST) et al. originally developed the deposition technology for metal oxides by just “coating and firing” the solution on a substrate by a metal organic deposition method. In this paper, focus was placed on the development of a fault current limiter for the application of high-temperature oxide superconductors to electrical devices. The paper gives the details of the research scenario for the selection and integration of the elemental technologies employed for the practical application of the MOD method.Electronic journalURL J-Stagehttp://www.aist.go.jp/aist_e/research_results/publications/synthesiology_e/ https://www.jstage.jst.go.jp/browse/syntheng
