Toward the implementation of geological CO2 storage, cost reduction of CO2 monitoring during and after injection into targeted reservoirs is the key issue. The continuous gravity measurement using a superconducting gravimeter, which has been applied to the demonstration project site in Japan ahead of the rest of the world, has a potential to resolve the issue from the viewpoint of a complement to the high-cost seismic survey. The concept is such that the continuous gravity measurement is substituted for constant monitoring and that the use of seismic survey could be limited only when any anomaly is detected. The comparison of the monitoring cost after the completion of CO2 injection indicated that applying gravity measurement can reduce costs by up to 15 to 50% of the seismic cost. The current detection limit of gravity change is around 1 μGal based on the application result in the coastal area in Japan. However, the time series analysis using pseudo gravity data suggested the possibility of anomaly detection even below the detection limit. Further improvement of analysis precision would lead not only to more rapid and more reliable anomaly detection but also to contribution to the cost reduction during the CO2 injection period.

The purpose of this study was to identify the learning sequence in the National Standards for Dance Education [NSDE]. To achieve this objective, we set the following three tasks;1) to identify the frameworks of learning sequences in each grade-band,2) to reveal the characteristics of content knowledge organized in Outlines of Sequential Learning,3) to illustrate the rationale behind the learning progression in Outlines of Sequential Learning.The results showed that;1) The learning sequence in dance education in the United States were structured in three grade-band, K-4, 5-8, and 9-12. In all grade-bands, development of not only motor skills, but also cognitive (creating and appreciating dance) and social emotional (establishing relationships with others) domains of learning in dance were expected to be acquired by students. Also, engagement in social activities relative to history and culture of dance were also identified as learning outcomes in the standards.2) In Outlines of Sequential Learning, three indicators provided achievement standards corresponding as to the three developmental stages. In particular, the achievement standards were not set up during content knowledge at that specific stage. The specific higher level standards enhanced the difficulty as integrating the lower level standards. The specific standards enhanced the difficulty not to change content knowledge, but to change the quality of achievement.3) In the process of developing Outlines of Sequential Learning, the developmental stages were set at first and then, in according to those stages, the achievement standards were described. The description on expected outcomes were differenent of each scopes. It means that the same achievement standards in sequential stages were described in some scopes and different others were changed in spite of same scopes. In addition, the amount of time to achieve appropriately was considerate.Overall, the learning sequence in the national standards for dance education in U.S.A. was structured based on the developmental characteristic of students and difficulty of the content. The consideration of content and the amount of time are critical to determine the learning sequences in national standards.
