Abstract  We combine the recent seismic reflection profiles to construct a new seismic velocity model of the sedimentary layer incorporating the accretionary prism along the Ryukyu trench. In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified.

Title Alternative An examination of decision-making support at the end of life on relational autonomy theory
FullText URL interdisciplinary_5_11.pdf
Author SONOYAMA, Sumiyo|
Abstract In contemporary end-of-life care, it is difficult for patients to make decisions without the influence of society, family, and other factors. In many cases, patients have the capacity to make the decisions; nevertheless, they have difficulty expressing their own will because of the influence of their relationships and environment. Patient concerns about the burden of care and also the social and economic impacts on family members often hinder their use of imagination and decision-making. Therefore, this study has examined how patients with decision-making capacities could achieve autonomy under the influence of their relationships with their surroundings. The method of decision-making support provided by nurses to patients was examined using relational autonomy theory. Relational autonomy theory attempts to reconceptualize autonomy through feminists who criticize individualist theories of autonomy.

Title Alternative Corporate decision-making process for exploration time
FullText URL interdisciplinary_5_1.pdf
Author SHIMIZU, Takeshi|
Abstract In order for companies to innovate through business co-creation, it is necessary to explore a wide range of external knowledge and technologies. However, there is no clear answer as to how much time should be spent for exploration. Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period. We conducted a case study of several companies that have introduced corporate accelerator program in Japan. In addition, this paper established a hypothesis about decision-making about the time for exploration from case studies.
