We obtain q-derivatives of Srivastava's general triple q-hypergeometric series with respect to its parameters. The particular cases leading to results for three Srivastava's triple q-hypergeometric series $H_{A,q}$, $H_{B,q}$ and $H_{C,q}$ are also considered.

We introduce q-special numbers and polynomials with q-exponential distribution. From these numbers and polynomials we derive some properties and identites. We also find approximated zeros of q-special polynomials and investigate property of two parameters ${\lambda}$, q.

In this paper, we introduce the concepts of q-cosine tangent polynomials and q-sine tangent polynomials. From these polynomials, we find some identities and properties by using q-numbers and q-trigonometric functions.

We study divisibilities of elements in the q-commuting matrix C^(q). We first make a coefficient matrix Ĉ of C^(q) which is independent of q, study divisibilities over Ĉ and then retrieve our findings to C^(q). Finally we partition the C^(q) into 2 × 2 block matrices.

자포니카 벼의 저온 스트레스 내성 증진을 위하여, RIL 계통을 이용하여 저온 스트레스 내성 QTL을 탐색하였다. 이를 통하여 (1) 5, 9번 염색체에서 저온발아에 관련한 '기호벼' 유래 QTL, qLTG5와 qLTG9를 확인하였으며, 7, 9번 염색체에서 저온 발아속도에 관련한 '밀양23호' 및 '기호벼' 유래 QTL, qOGCV7, qOGCV9를 확인하였다. (2) Duncan 검정결과, 그룹VII [qLTG5+qLTG9 (qOGCV9)], 그룹VIII [qLTG5+qOGCV7+qLTG9 (qOGCV9)]의 계통들이 저온 스트레스에 내성이 있는 것으로 확인 되었다. (3) 최근 발표된 RIL 집단 담수내성 계통과 비교한 결과, 저온 스트레스에도 내성이 있으면서 담수발아에도 내성이 있는 것으로 확인된 총 2개의 유망 유전자원을 선발하였다. 본 연구의 결과를 통해 저온 및 혐기 관련 QTL의 집적은 벼의 저온에서의 발아 및 초기 입모율을 높여 저온스트레스 내성 개선에 도움이 되는 것으로 판단 되었으며, 선발된 유망 계통은 향후 직파재배 품종 육성에 유용한 유전자원으로 활용되어 직파재배의 안정성 증대에 기여할 것으로 기대된다.

Quercus aliena and Q. serrata are both occur as natural vegetation alongside natural freshwater bodies of the southern Korea Peninsula. Q. serrata dominates over Q. aliena as secondary forest vegetation in the present day. In order to explain these natural distributional traits of the oak species, we conducted some experiments with oak seedlings which treated with major important environmental resources, including light, moisture and nutrients, under controlled conditions. We then measured the ecological niche breadths and overlap from 15 eco-morphological characteristics. The ecological niche breadth of Q. aliena and Q. serrata were higher in terms of the nutrient factor applied, but was lower terms of light. The niche breadth of Q. serrata was wider than that of Q. aliena in light and moisture exposure. On the other hand, the niche breadth of Q. aliena was similar with that of Q. serrata in terms of the nutrient factor applied. These results imply that Q. serrata has a broader ecological distribution in over a wider variety of light and moisture environments than that of Q. alien. Ecological niche overlap between two oak species was the widest in terms of the light treatment factor applied, and narrowest in terms of moisture. This response pattern was also verified by cluster and principle component analysis. These results suggest competitive interactions between Q. serrata and Q. aliena seedlings may be higher for light resources than moisture or nutrient resources, and that Q. serrata is more shade tolerant than Q. aliena.

석회석 광산 갱도 내 22 곳의 측정지점을 선정하여 RMR, Q-system, GSI와 같은 암반분류법을 적용하였다. SRF와 $J_w$를 1로 한 수정 Q(Q')와 지하수 조건을 '완전 건조'로 하고 불연속면의 방향 보정을 '0'으로 한 수정 RMR(${RMR_{89}}^{\prime}$)도 계산하였다. Q-기본 RMR, Q-최종 RMR, ${GSI-RMR_{89}}^{\prime}$, GSI-Q' 간의 상관관계를 분석한 결과 ${GSI-RMR_{89}}^{\prime}$ 의 상관성이 가장 높은 것으로 나타났다. 계수비를 기초로 파괴 변형률을 구했으며, 대부분의 측정지점이 '낮은 파괴 변형률' 등급에 속하는 것으로 나타나 안정한 것으로 평가되었다.

Let D be the open unit disk in the complex plane $\mathbb{C}$. For any q > 0, the operator $Q_q$ defined by $$Q_qf(z)=q\int_{D}\frac{f(\omega)}{(1-z{\bar{\omega}})^{1+q}}d{\omega},\;z{\in}D$$. maps $L^{\infty}(D)$ boundedly onto $B_q$ for each q > 0. In this paper, weighted Bloch spaces $\mathcal{B}_q$ (q > 0) are considered on the open unit ball in $\mathbb{C}^n$. In particular, we will investigate the possibility of extension of this operator to the Weighted Bloch spaces $\mathcal{B}_q$ in $\mathbb{C}^n$.

Recently, q-Dedekind-type sums related to q-Euler polynomials was studied by Kim in [T. Kim, Note on q-Dedekind-type sums related to q-Euler polynomials, Glasgow Math. J. 54 (2012), 121-125]. It is aim of this paper to consider a p-adic continuous function for an odd prime to inside a p-adic q-analogue of the higher order Dedekind-type sums with weight related to modified q-Euler polynomials with weight by using Kim's p-adic q-integral.

In reinforcement teaming, Q-learning converges quite slowly to a good policy. Its because searching for the goal state takes very long time in a large stochastic domain. So I propose the speedup method using the Q-value initialization for model-free reinforcement learning. In the speedup method, it learns a naive model of a domain and makes boundaries around the goal state. By using these boundaries, it assigns the initial Q-values to the state-action pairs and does Q-learning with the initial Q-values. The initial Q-values guide the agent to the goal state in the early states of learning, so that Q-teaming updates Q-values efficiently. Therefore it saves exploration time to search for the goal state and has better performance than Q-learning. 1 present Speedup Q-learning algorithm to implement the speedup method. This algorithm is evaluated. in a grid-world domain and compared to Q-teaming.
