Making use of the multidimensional fractional calculus operators introduced in [20], this paper gives the images under these operators of the celebrated Fox's H-function. Special cases are briefly point out, and some of the results are also studied on general spaces of functions $M_{\lambda}(R_{+}^n)$.

The paper aims to analyse the development of algebra and calculus during the Scientific Revolution. It will argue that the introduction of algebra into the learning world was never smooth but invited struggle with traditional geometry, which is well illustrated in the development of calculus in the 17th century. The paper will also demonstrate that the invention and the acceptance of calculus had been influenced by the need of solving practical problems (e. g., motion) during the century.

We show how some interesting results involving series summation and the digamma function are established by means of Riemann-Liouville operator of fractional calculus. We derive the relation $$ \frac{\Gamma(\lambda)}{\Gamma(\nu)} \sum^{\infty}_{n=1}{\frac{\Gamma(\nu+n)}{n\Gamma(\lambda+n)}_{p+2}F_{p+1}(a_1, \cdots, a_{p+1},\lambda + n; x/a)} = \sum^{\infty}_{k=0}{\frac{(a_1)_k \cdots (a_{(p+1)}{(b_1)_k \cdots (b_p)_k K!} (\frac{x}{a})^k [\psi(\lambda + k) - \psi(\lambda - \nu + k)]}, Re(\lambda) > Re(\nu) \geq 0 $$ and explain some special cases.

In this paper, we discuss how the operational calculus can be exploited to the theory of mixed generating functions. We use operational methods associated with multi-variable Hermite polynomials, Laguerre polynomials and Bessels functions to drive identities useful in electromagnetism, fluid mechanics etc. Certain special cases giving bilateral generating relations related to these special functions are also discussed.

This paper presents a fundamental theorem of calculus, an integration by parts formula and a version of equiintegrability convergence theorem for the M_α-integral using the M_α-strong Lusin condition. In the convergence theorem, to be able to relax the condition of being point-wise convergent everywhere to point-wise convergent almost everywhere, the uniform M_α-strong Lusin condition was imposed.

Information Technology influenced on classroom to change the teaching and learning method. Recently, flipped learning method became a hot issue in education by using Information Technology. Learning management system that is introduced in our university in the spring semester 2015, made it possible to apply flipped learning method. So, we used the flipped learning method in a calculus course. In this paper, we found that flipped learning in Calculus we was a little bit affirmative in the aspect of motivation and active learning from students' response on flipped learning method. We analyzed the reason that students were not so positive in continuing flipped learning even though they liked flipped learning a little bit better than traditional learning. We suggest what we pay attention to for applying the flipped learning method effectively.

The purpose of this study was to develop an effective Calculus Supplement Learning Program for university students who are from liberal arts and investigate how the program affects their achievement and attitude in mathematics. we analyzed their answer sheets and interview reports with qualitative methods. After adapting the program, students recognized that mathematical concepts and definitions were very important to study a college calculus. Also they picked up how to learn mathematics in college. Finally, we found that students could develop their abilities of proof, problem solving, and logical thinking through the program.

Identification of blood group from the saliva and calculus of the Purpose of individual identification would play a significant role in a practical legal medicine. The author made a study of blood group with saliva and in non-secretor type with dental calculus. The following results were obtained. 1. In the blood typing with saliva obtained from 50 people, secretor type was found 22.4% and non-secretor type was found 27.6%. 2. In Sexual difference, secretor type 70.9%, non-secretor type 29.1% in male and secretor type 73.8%, non-secretor type 26.2% in female were found. 3. In blood group difference, secretor type 80.2% nonsecretor type 19.8% in A blood group, secretor 70.4%, nonsecretor type 29.6% in B blood group, secretor type 66.7% nonsecretor type 33.3% in AB blood group, secretor type 68.2% nonsecretor type 31.8% in O blood group were found. 4. The blood group identification with dental calculus in nonsecretor type proved to be possible. 5. The blood group substance was found in the composition of dental calculus itself regardless of that in saliva.

본 연구에서는 패턴을 갖는 항 개서 체계(TRS, Term Rewriting Systems)의 룰을 람다 계산법으로 코딩하는 변환 방법을 제시한다. Böhm의 분리성 이론에 따라 차별화된 룰 패턴을 갖는 분리 시스템은 람다 계산법으로 변환될 수 있음을 보인다. 또한, Böhm 동등 부류의 특성을 적용함으로써, 이 변환은 디폴트 룰로 된 개서 시스템을 코딩할 수 있으며 TRS의 '의미 없는 팀'들을 동일한 람다 팀으로 해석할 수 있도록 한다.

Disentangling is the essential operation of Feynman's operational calculus for noncommuting operators. Thus formulas which simplify this operation are central to the subject. In a recent paper the procedure for 'extracting a linear factor' has been established in the setting of Feynman's operational calculus for time independent operators $A_1, ... , A_n$ and associated probability measures ${\mu}_1,..., {\mu}_n$. While the setting just described is natural in many circumstances, it is not natural for evolution problems. There the measures should not be restricted to probability measures and it is worthwhile to allow the operators to depend on time. The main purpose for this paper is to extend the procedure for extracting a linear factor to this latter setting. We should mention that Feynman's primary motivation for developing an operational calculus for noncommuting operators came from a desire to describe the evolution of certain quantum systems.m systems.
