This study examined the effects of cognitive training by e-sports on the elderly and their willingness to participate in training. Methods: Twelve healthy elderly subjects played "Puyo Puyo" in a competitive format for 2 months (8 sessions). The effects of the training were analyzed by evaluating the subjects with the MMSE, CPT, Stroop test, and TMT before and after the training, and by evaluating the subjects with the Stroop test and TMT at 4 months after the training. In addition, a questionnaire survey on participation was conducted at the end of the training period. In order to confirm the learning effect of the test, six healthy elderly subjects who did not participate in the training were evaluated by the MMSE, Stroop test, and TMT. Results and Discussion: There were significant differences in the number of correct responses to the Stroop test and the time required to perform the TMT in the trained group compared to the untrained group. No significant differences were found in the untrained group. The questionnaire results indicated that the participants were motivated to participate in the training, suggesting that e-sports cognitive training improves general attentional function in healthy elderly people and encourages their active participation in the training.

We collected various data from the active fault map of the urban area (Geographical Survey Institute) and long-terme valuation for active faults (Headquarters for Earthquake Research Promotion), and investigated a survey of 334 land uses on flexure zones throughout Japan. Regarding to the slope of the flexure zone, residential and commercial buildings that occupied 28% at 0◦ ≦ slope < 5◦decreased to 9% at 20◦ ≦ slope < 25◦, also the forest that occupied 11 ％ at40◦ ≦ slope < 5◦increased to 68% at 20◦ ≦ slope < 25◦. The characteristics of land use changed in slope. Analyzing the trends in each region, Hokkaido, Tohoku, and Chubu regions are known that larger than other regions for agricultural production, and the same tendency appears in land use on flexible zones. 37%, 41%, and 43% were used as agricultural land in these areas. On the other hand, the Kanto and Kinki region that have cities with concentrated populations occupied 59%, 61% at residential and commercial buildings and public buildings. Focusing on the flexure zone located in the ordinance-designated city, 70% of the land on the flexure zone was used for buildings used by people.
