<p>The TWINCLE program is a teacher internship program which aims to enhance mutual understanding of foreign cultures and to develop students' ability to succeed in overseas internships. In this study, reports written by students who participated in the program were analyzed by a text mining method to evaluate the changes in their ideas about the development and practice of the teaching materials. The results indicate that the students' attitudes towards science classes changed from 'simple lecture oriented classes' to 'problem-solving learning oriented classes'. Therefore, participating in the TWINCLE program is an effective way to change the students' image of the science class.</p>

In this paper, a class of minimization problems, labeled by an index 0 &lt; h &lt; 1, is considered. Each minimization problem is for a free energy, motivated by the magnetics in 3D-ferromagnetic thin film, and in the context, the index h denotes the thickness of the observing film. The Main Theorem consists of two themes, which are concerned with the study of the solvability (existence of minimizers) and the 3D-2D asymptotic analysis for our minimization problems. These themes will be discussed under degenerate setting of the material coefficients, and such degenerate situation makes the energy-domain be variable with respect to h. In conclusion, assuming some restrictive conditions for the domain-variation, a definite association between our 3D-minimization problems, for very thin h, and a 2D-limiting problem, as h \ 0, will be demonstrated with help from the theory of F-convergence.
