What is the life of an assistant professor working at a college of education look like? The purpose of this paper is to describe and understand the life of an assistant professor as a science education researcher and as a teacher educator from exploring his life in a local national university. The researcher (I) conducted an autobiographic research in which I reconstructed and reflected my life by myself. I collected data/records on the life of myself, and developed a framework to classify them. The life of an assistant professor was categorized into the official life at the university and the personal life, and the former was sorted into education, research, and service and the latter was divided into personal and family. From the various profiles of my life, I found the main theme of 'change' and 'learning,' from which I reconstructed my life in narratives. I can express myself as an assistant professor with 'from myself to others,' 'balancing society and isolation,' and 'increasing room to maneuver through continuous learning.' I reflected my life and the role of a professor at a college of education, and discussed the educational implication of the result.

Magnetic method is rapid, cheap and simple geophysical exploration technique, and has wide range of applications such as resources prospecting, geological structure investigation and even geotechnical and environmental problems. Documents during Japanese occupation says that magnetic method was used for exploring metallic ore deposits and hot spring, and that a geomagnetic observatory was operated. From mid 1950's, magnetic explorations for natural resources such as metallic ore, uranium, coal, and groundwater were intensively executed for industrialization. Magnetic survey techniques were rapidly advanced during 1970's and 1980's with improvements of instruments, growth of geophysical manpower, and availability of computers. Decline of mining industry since mid 1980's moved the exploration objects from traditional resources to new ones such as groundwater and geothermal resources. Recently appeared applications such as natural hazard assessment, and engineering and environmental studies increased the magnetic method's utility in the realm of exploration.
