Regarding the construction of an ultra-high vacuum environment necessary for the analysis of solid surfaces, the change in vacuum degree was indeed measured using a gas transport vacuum pump (TMP: turbo molecular pump) and gas storage vacuum pump (ion pump or getter pump). Because the compression ratio of TMP is constant, the ultimate pressure of TMP can be reduced by lowering the exhaust port pressure. Notably, the method of connecting two TMPs in series had a higher exhaust speed than the method of connecting them in parallel. In the future, we plan to use the vacuum environment for electron spectroscopy experiments on the surface of solid materials.

This study investigated the actual situation of System of Small Chartered Schools in Ishikawa Prefecture, and organized the process of introduction at each school. In addition, we identified the method of commuting to school, commuting support, changes in the number of students, and the percentage of students commuting from outside the school district. Based on the above survey results, a classification was made and future issues were organized. In addition, it is likely that in the future it will be more important to understand the barriers and challenges for schools to continue to exist after the introduction of the system, rather than the conditions for an increase in the number of System of Small Chartered Schools.
