This paper establishes a formula changing the ring from a Noetherian local ring A of dimension d > 0 containing the residue field k to the polynomial ring in d variables k[X₁, X₂, …, X_d] for mixed multiplicities. And as consequences, we get a formula for the multiplicity of Rees rings and formulas for mixed multiplicities and the multiplicity of Rees rings of quotient rings of A by highest dimensional associated prime ideals of A.

Bearman's rotation theorem is not only very important in pure mathematics but also plays the key role for various research areas, related to Wiener measure. In 2002, the author and professor Im introduced the concept of analogue of Wiener measure, a kind of generalization of Wiener measure and they presented the several papers associated with it. In this article, we prove a formula on analogue of Wiener measure, similar to the formula in Bearman's rotation theorem.

Recently, K. Watanabe Showed that the Hilbert-Kunz multiplicity of a toric ring is a rational number. In this paper we give an explicit formula to compute the Hilbert-Kunz multiplicity of two-dimensional toric rings. This formula also shows that the Hilbert-Kunz multiplicity of a two-dimensional non-regular toric ring is at least 3/2.

The object of this note is to derive Padmanabham's transformation formula for Exton's triple hypergeometric series $X_8$ by using a different method from that of Padmanabham's. An interesting special case is also pointed out.

In this study, students' multiplication expression method according to visual model was analyzed through paper test and eye tracking test. As a result of the paper-pencil test, students were presented with multiplication formula. In the group model (number of individual pieces in a group) ${\times}$ (number of group) in the array model (column) ${\times}$ (row), but in the array model, the proportion of students who answered the multiplication formula in the (row) ${\times}$ (column). From these results, we derived the appropriate model presentation method for multiplication instruction and the multiplication expression method for visual model.

Objective : This study aimed to investigate Korean medical students' satisfaction with Korean medicine education and their trust in Korean medicine. It also explored the factors affecting satisfaction with Korean medicine education and trust in Korean medicine. Methods : Based on a total of 381 survey responses, the satisfaction with Korean medicine education, reflection of educational needs, trust in Korean medicine, reasons for maladjustment to education, and suggestions for improving education were analyzed. Results : Satisfaction with Korean medicine education and trust in Korean medicine were generally above average. However, reflection of educational needs was below average. It was found that the curriculum should be rearranged according to the needs of premedical students and medical students. The factors affecting satisfaction with Korean medicine education were gender, academic year, dropout experience, trust in Korean medicine, and reflection of educational needs. Factors affecting trust in Korean medicine were gender, academic year, and satisfaction with Korean medicine education. Conclusion : This study found that satisfaction with Korean medicine education and trust in Korean medicine have a reciprocal relationship. To improve students' satisfaction and adjustment to Korean medicine education, it is necessary to implement strategies to increase students' trust in Korean medicine. In addition, it is important for students and instructors to collaborate on curriculum design by establishing a feedback system that reflects students' needs.

The notion of a parabolically semistandard tableau is a generalisation of Young tableau, which explains combinatorial aspect of various Howe dualities of type A. We prove a Jacobi-Trudi type formula for the character of parabolically semistandard tableaux of a given generalised partition shape by using non-intersecting lattice paths.

Taylor's formula is a powerful tool in analysis. In this study, we assume that an operator is m-times Fr$\acute{e}$chet-differentiable and satisfies a Lipschitz condition. We then obtain some Taylor formulas using only the Lipschitz constants. Applications are also provided.

In this paper, using a transformation formula for a certain series which comes from the generalized non-analytic Eisenstein series, we obtained some infinite series identities which contain Ramanujan's formula and author's previous results.
