Recently, Kim et al. introduced the type 2 Daehee and Changhee polynomials and give some new identities for these polynomials and numbers. In this paper, we study type 2 Daehee and Changhee polynomials and numbers arising from p-adic integrals on Zp. Regarding to those polynomials and numbers, we investigate some identities, Witt's formula, and distribution relation of these polynomials and numbers.
On one nonlinear optimal control problem with fixed ends
권종겸,D. Dolgy,장관우,김태균 장전수학회 2018 Advanced Studies in Contemporary Mathematics Vol.28 No.4
We consider nonlinear general problem of optimal control with fixed ends and apply two approaches for its solving: Pontryagin maximum principle and Galerkin method. We developed the new method of obtaining approximate solution for this problem and explored its basic properties.
Some identities of central Fubini polynomials
권종겸,김대산,장이채,Yonghong Yao 장전수학회 2019 Advanced Studies in Contemporary Mathematics Vol.29 No.2
In this paper, we derive two symmetric identities, on involoving the ω-torsion central Funibi polynomials and the central factorial numbers of the second kind and the other involving the ω-torison two variable central Funibi polynomials by using the fermionic ρ-adic integrals on Zp.
Control of the wireless power transfer circuit
권종겸,장이채,김태균,Dmitriy Dolgy 장전수학회 2020 Advanced Studies in Contemporary Mathematics Vol.30 No.3
We consider one of the most popular wireless power transfer circuits, formalize it as the optimal control problem and apply Pontryagin maximum principle for obtaining its solution.
A NOTE ON THE TYPE 2 POLY-APOSTOL-BERNOULLI POLYNOMIALS
권종겸,장이채 장전수학회 2020 Advanced Studies in Contemporary Mathematics Vol.30 No.2
Recently, Kim-Kim ([6]) have studied the type2 poly-Bernoulli poly- nomials by using the polylogarithm functions. In this paper, we dene the type 2 poly-Apostol-Bernoulli polynomials and investigate some properties for them. Furthermore, by making use of unipoly function, we dene the type 2 unipoly- Apostol-Bernoulli numbers and show some basic properties for them.
초등학교 1·2학년 스토리텔링 기반 수학교과서 적용을통한 교사의 인식 변화
권종겸,이영혜,이봉주 대한수학교육학회 2013 학교수학 Vol.15 No.4
At the point when textbooks based on storytelling have been used in math classes for elementary first and second grades, this research analyzed any changes in perspectives of in-service teachers towards storytelling education, to promote further application for teaching and learning math by storytelling in the future. 30 in service teachers who have used math textbooks based on storytelling were surveyed in March and in July, 2013. For the better understanding of the survey results, four of the subjects were selected and interviewed. Consequently, teachers' perspectives towards the appropriateness and efficiency of the storytelling education did not change significantly. It also suggested that the most suitable area for storytelling is measurement, the least suitable area is geometry, and storytelling by real-life applications is effective in teaching elementary math. 이 연구의 목적은 초등학교 1학년과 2학년 수학교육에 스토리텔링을 기반으로 한 수학교과서가 적용된 지 한 학기가 지난 시점에서 스토리텔링 수학 교수․학습에 대한 초등학교 1․2학년 교사의 인식 변화를 조사함으로써 향후 스토리텔링 수학 교수․학습을 지원하기 위한 시사점을 도출하는 것이다. 이를 위하여 2013년 3월에 스토리텔링 수학 교수․학습에 대한 인식 조사에 참여한 초등학교 1․2학년 담당 교사 30명을 대상으로 같은 해 7월에 설문조사를 실시하고, 이들 중 4명의 교사를 대상으로 면담을 진행하였다. 분석 결과, 초등학교 1․2학년 스토리텔링 수학 교수․학습의 적절성과 효율성에 대한 인식 변화에 유의미한 차이가 없는 것으로 나타났다. 스토리텔링 수학 교수․학습이 가장 적합한 영역을 측정 영역으로, 가장 부적합한 영역을 도형 영역으로 인식하였고, 실생활 연계형을 효과적인 스토리텔링 유형으로 인식하는 것으로 나타났다.
반성적 수업 분석지를 활용한 교육실습에서 중등수학 예비교사의 교수행동 및 인식 변화
권종겸,Kwon, JongKyum 한국수학사학회 2014 Journal for history of mathematics Vol.27 No.5
The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.

SOME IDENTITIES OF THE POLY-CHANGHEE AND UNIPOLY CHANGEE POLYNOMIALS
권종겸,박진우,윤상조 장전수학회 2021 Advanced Studies in Contemporary Mathematics Vol.31 No.4
Recently, several authors studied the degenerate q-special polynomials related to L. Carlitz’s degenerate polynomials. In this paper, we introduced the Carlitz’s type degenerate q-Changhee numbers and polynomials. Also, we study some explicit identities and properties for the Carlitz’s type degenerate q-Changhee numbers and polynomials arising from p-adic invariant q-integral on Zp.
