Sediment causes a serious problem in relation to dam function. A cooperative sediment sluicing operation has been under way since 2017 to prevent sediment from accumulating in dams in the Mimi River, Miyazaki, Japan. To achieve a smooth and stable operation, it is very important to determine the sediment source and a sediment transport system to maintain the dam's function. In the current study, the source and transport of sediment from the Mimi River basin have been analyzed with X-ray diffraction (XRD) to reveal the peaks of mineral species. The sediment samples were collected in the Mimi River basin from the Tsukabaru Dam to the sea in an area including 4 dams and 5 tributaries. In addition, the minerals in samples collected in 2014, before the start of the sediment sluicing operation, and from 2018 to 2020, after the start of the operation, were analyzed. An evaluation of the similarity of the sediment at each sampling point based on the X-ray diffraction peaks of mineral species showed that sediment distributed upstream was transported downstream in the year when the sediment sluicing was done. This result indicates that the sediment sluicing operation at dams ensured the continuity of the sediment distribution in the Mimi River basin. In addition, an investigation done in 2020 showed that sediment particles very similar to those of the upstream tributaries were deposited downstream because of extensive flooding caused by a large typhoon. The management of sediment transport has the greatest importance in a river basin where a dam is to be constructed. It is possible to trace the history of the sediment distribution and movement resulting from the operation of sediment sluicing by using sediment mineral analysis.

There has been an issue of a mismatch between the types of businesses and occupations sought
by international students and local communities when it comes to finding employment for
international students in regional areas. Therefore, the University of Miyazaki, Miyazaki City office,
the Japan International Cooperation Agency, and local companies collaborated to implement the
“Miyazaki-Bangladesh Model” to support the employment of highly skilled foreign professionals in
the ICT field through education before coming to Japan “B-JET” and short-term study abroad “JIP”.
For the B-JET, original Japanese language teaching materials were developed and used, and additionally, the class schedule and classroom management were similar to Japanese elementary and junior high schools with small classes in order to have the students acquire Japanese social customs. For JIP, in addition to Japanese language education, the students were given internships at companies that decide to employ them. At the same time, in order to promote cross-cultural understanding on the part of host companies that are not familiar with foreigners and to enhance their readiness to accept foreign engineers, company representatives as tutors were provided for support for students. As a result, 73% of the students who completed the B-JET, entered employment in Japanese companies, with one-third of them working for companies in Miyazaki Prefecture.
