  • Purpose - The industrial structure upgrading can play an important role in promoting the carbon emission efficiency. Thus, this paper attempts to study the impact of industrial structure upgrading on carbon emission efficiency in order to reduce carbon emissions. Research design, data, and methodology - This paper selects panel data of 30 provinces and municipalities (autonomous regions) in China from 2001 to 2016, and divides them into three regions. The Moore index is used to measure the industrial structure upgrading, the non-radial SBM model based on undesired output is used to measure the slack variable to calculate the total factor carbon emission efficiency. Finally the impact of industrial structure upgrading on the carbon emission efficiency are analyzed. Results - It is found that the Moore index and the carbon emission efficiency in the eastern region is the highest in the three regions. Conclusions - The influence of various influencing factors on carbon emission efficiency is different between regions. The Moore index has a positive effect on the carbon emission efficiency in the eastern region, and has a negative influence coefficient on the central region. The effect on the western region is not obvious.

  • 최근 단일 은닉층을 갖는 전방향 신경회로망 구조로, 기존의 경사 기반 학습알고리즘들보다 학습 속도가 매우 우수한 ELM(Extreme Learning Machine)이 제안되었다. ELM 알고리즘은 입력 가중치들과 은닉 바이어스들의 초기 값을 무작위로 선택하고 출력 가중치들은 Moore-Penrose(MP) 일반화된 역행렬 방법을 통하여 구해진다. 그러나 입력 가중치들과 은닉층 바이어스들의 초기 값 선택이 어렵다는 단점을 갖고 있다. 본 논문에서는 최적화 알고리즘 중 박테리아 생존(Bacterial Foraging) 알고리즘의 수정된 구조를 이용하여 ELM의 초기 입력 가중치들과 은닉층 바이어스들을 선택하는 개선된 방법을 제안하였다. 실험을 통하여 제안된 알고리즘이 많은 입력 데이터를 가지는 문제들에 대하여 성능이 우수함을 보였다.

  • "p이지만 나는 p라고 믿지 않는다"와 같은 문장은 어떤 상황에서도 자연스럽게 발화될 수 있을 것 같지 않고, 심지어는 부조리하고 모순되게 들리기까지 한다. 무어의 역설이 제기하는 문제는 왜 이런 문장이 아무런 형식적인 모순이 없음에도 불구하고 이를 발화하는 것이 부조리하게 들리는지를 설명하는 것이다. 무어의 역설에 대한 기존의 견해는 주로 믿음이나 주장(assertion)의 성격에서 그 부조리성의 근원을 찾으려 한다. 필자는 본 논문에서 기존의 견해들이 무어의 역설을 만족스럽게 설명하지 못함을 주장하고, 이에 대한 새로운 설명을 제안한다. 이 제안에 따르면 무어의 역설의 근원은 "자기-지시"에 있다. 자기-지시는 주체가 어떤 특정한 방식으로 믿음을 형성하는 성향에 의해 부분적으로 구성되는데, 무어의 역설은 주체가 자신을 "나"로 지시하는 동시에 어떤 사람을 "나"로 지시하기 위해 만족시켜야할 조건을 만족시키지 못하는 데에서 발생한다.

  • 분석의 역설을 처음으로 명확하게 자각하고, 이를 회피할 방안을 제시한 사람은 무어(G. E. Moore)이다. 여기서는 이 역설의 해결책을 무어식의반-언어적 노선과 이에서 벗어나 있는 노선으로 나누어 제시한다. 후자에는 개념의 특징 및 종류, 명제의 구조, 비동등성 관계에 주목해서 역설을 회피하려는 전략이 있다. 본 논문의 일차적인 목적은 주요 역설해결책을 기술하고 그 분류를 제시하는 것이지만, 이와 더불어 또한 각 해결 전략의 한계를 논하도록 하겠다. 그런데 이런 논의를 효율적으로 전개하려면, 먼저 무어의 분석이론을 재구성하는 일이 필요하다. 무어의 분석이론은, 단지 역사적인 중요성뿐 아니라, 고전적 분석의 전형을 이룬다는 점에서도 관심의 대상이 되기에 충분하다. 또한 분석의 역설이 고전적 분석과 같이 특정 유형의 분석에만 해당한다는 주장에 반대하여 넓은 범위의 분석에서 발생한다고 주장하겠다. 그러나 더불어 이런 상황이 분석의 무용성을 보여주는 것은 아니라고 주장하겠다.

무어, 로월과의 관계 속에서 엘리자베스 비숍 읽기 -비숍 시의 "내적 특성" 들여다보기 (Reading Elizabeth Bishop in Her Relationship with Moore and Lowell: Looking into the "Intrinsic Qualities" of Bishop's Poetry)

  • This study explores the characteristics of Elizabeth Bishop's poetry in comparison with the two of her closest friends and poets, Marianne Moore and Robert Lowell. Bishop's reputation has dramatically changed since her death. In the 1970s she was "a writer's writer's writer," and admired by a small group of poets or critics. Since 1990s, however, there has been a great shift in the evaluation of her poetry, which is so called "The Elizabeth Bishop Phenomenon." It does not seem to be an easy task to examine what has driven the phenomenon, and why she used to be a minor poet or "the most honored yet most elusive of poets" but now she has a widespread recognition by the academy and beyond it. The "intrinsic qualities" of Bishop's poetry, however, can be one of the main reasons why it took several decades for Bishop to become a central figure in the literary canon. Looking into her "intrinsic qualities," this paper discusses Bishop's "The Fish," "Roosters" through the Moore-Bishop relationship, and reads Bishop's "Armadillo" and "The Monument" through the Lowell-Bishop relationship. It also deals with letters, interviews, Moore's "The Fish," and Lowell's "Skunk Hour" and "For the Union Dead" to show the Bishop's deep and complex relationships with the two poets, and more importantly their differences. Bishop's poetry is difficult, "elusive," and sometimes "enigmatic," not because her texts are full of difficult words to understand but because there are the subtle interchange between perception and meaning, "the dynamics of keen feeling," the unresolved patterns, and the transient vision under the seemingly transparent surface of the texts.

  • A higher order iterative method to compute the Moore-Penrose inverses of arbitrary matrices using only the Penrose equation (ii) is developed by extending the iterative method described in [1]. Convergence properties as well as the error estimates of the method are studied. The efficacy of the method is demonstrated by working out four numerical examples, two involving a full rank matrix and an ill-conditioned Hilbert matrix, whereas, the other two involving randomly generated full rank and rank deficient matrices. The performance measures are the number of iterations and CPU time in seconds used by the method. It is observed that the number of iterations always decreases as expected and the CPU time first decreases gradually and then increases with the increase of the order of the method for all examples considered.

  • The real moment-angle complex (or, more generally, real polyhedral product) and its real toric space have recently attracted much attention in toric topology. The aim of this paper is to give two interesting remarks regarding real polyhedral products and real toric spaces. That is, we first show that Moore's conjecture holds to be true for certain real polyhedral products. In general, real polyhedral products show some drastic difference between the rational and torsion homotopy groups. Our result shows that at least in terms of the homotopy exponent at a prime this is not the case for real polyhedral products associated to a simplicial complex whose minimal missing faces are all k-simplices with $k{\geq}2$. Moreover, we also show a structural theorem for a finite group G acting simplicially on the real toric space. In other words, we show that G always contains an element of order 2, and so the order of G should be even.

  • Let $\cal{H}$ and $\cal{K}$ be Hilbert spaces and let T, $\tilde{T}$ = T + ${\delta}T$ be bounded operators from $\cal{H}$ into $\cal{K}$. In this article, two facts related to the perturbation bounds are studied. The first one is to find the upper bound of $\parallel\tilde{T}^+\;-\;T^+\parallel$ which extends the results obtained by the second author and enriches the perturbation theory for the Moore-Penrose inverse. The other one is to develop explicit representations of projectors $\parallel\tilde{T}\tilde{T}^+\;-\;TT^+\parallel$ and $\parallel\tilde{T}^+\tilde{T}\;-\;T^+T\parallel$. In addition, some spectral cases related to these results are analyzed.

  • We study torsion phenomena in the integral cohomology of finite if-spaces X through the Eilenberg-Moore spectral sequence converging to H*($\Omega$X; Z$_{p}$). We also investigate how the difference between the Z$_{p}$-filtration length f$_{p}$(X) and the Z$_{p}$-cup length c$_{p}$(X) on a simply connected finite H-space X is reflected in the Eilenberg-Moore spectral sequence converging to H*($\Omega$X;Z$_{p}$). Finally we get the following result: Let p be an odd prime and X an n-connected finite H-space with dim QH* (X;Z$_{p}$) $\leq$ m. Then H*(X;Z) is p-torsion free if (equation omitted).tion omitted).
