In this paper, we present the investigation of influence of time variant sample number for estimation results of shallow water flow using the ensemble Kalman filter FEM. The shallow water equation is employed as the governing equation, and the SUPG method is applied to discretize the governing equation. In this study, estimation results are compared by changing the sample number in time.

In this paper, we present the numerical analysis of the magnetic density distribution based on the three dimensional finite element method. In this study, the comparison of the numerical results was carried out under the conditions with and without assumption of the coulomb gauge. Consequently, we confirmed that appropriate magnetic density distribution can be obtained by considering the condition of the coulomb gauge.

In this paper, we present the investigations for effect of penalty parameter in temperature field analysis for bonded materials based on the discontinuous Galerkin finite element method. The penalty parameter is used in the discontinuous Galerkin finite element method, and effect of discontinuity can be changed by changing this parameter. Therefore, in this study, investigation for effect of the penalty parameter is carried out in temperature field analysis.

This research explored the possibility of implementing a holistic evaluation instead of an analytic evaluation for the English speech contest. Ten speakers were evaluated by their scores based on the sub-rank method. The participants of the two different evaluation systems were 52 incumbent English teachers grouped into three kinds of English abilities: 17 Japanese English teachers who were second level for the Society for Testing English Proficiency(STEP), 20 Japanese English teachers who were more than pre-first level for STEP, and 15 native English speakers who were Assistant Language Teachers(ALTs). This research clarified three results: (a)there were no significant differences between the holistic evaluation and the analytic evaluation relating to the score of ten speakers. However, it revealed a significant difference concerning the score of two speakers between the 2nd level teachers for STEP and the ALTs; (b)the holistic evaluation significantly reduced the evaluating time compared to the analytic evaluation; (c)it was also apparent that the participants never thought that holistic evaluation was easier than analytic evaluation.

Students in National Institute of Technology, Nagaoka College (Nagaoka Kosen) have various different opportunities to experience lives in foreign countries such as Malaysia, Thailand, Mongolia, Mexico and Russia. They do not just experience their foreign cultures, they also have opportunities to work with the local students in order to foster their interpersonal communication skills and problem solving skills. However, none of those programs focuses on their English language competency. In 2018, Nagaoka Kosen received one of the competitive grant called Kosen Initiative 4.0 from Japanese government, and it gave us a chance to create a new program to nurture gobal-minded engineering students. In addition to the existing study abroad programs we now have in Nagaoka Kosen, we have visited the Bay Area in North California near San Francisco and University of Nevada, Reno to develop a new study abroad program. Our plan and possibility to create a new English-Learning Study Abroad Program are dicussed on this paper.
