The purpose of this study was to examine the perception of students about pseudo-science in consideration to their personality traits, cognitive style, and awareness of the nature of science, which might all have a great impact on their behavior and thinking. The subjects of this study were 129 sixth-grade school children in a small urban community in Gyeonggi province. The way they looked at pseudo-science was investigated after three kinds of traits were selected as variables, including personality traits, cognitive style, and awareness of the nature of science. Four different instruments were utilized, which respectively covered personality traits, cognitive style, awareness of the nature of science and perception of pseudo-science. The results of the study were as follows: First, the children with higher emotional stability and liveliness showed higher permeability towards pseudo-science, while made no significant difference on their view of pseudo-science. Second, their cognitive style made no significant difference to their outlook on pseudo-science. Third, as for link between awareness of the nature of science and pseudo-science, the students with a poor understanding of the nature of science were significantly different from those who had a better understanding of it in perception of pseudo-science(p<.05).

In this paper, we define a new algebraic structure known as a generalized pseudo BE-algebra which is a generalization of a pseudo BE-algebra. We construct some examples in order to show the existence of the generalized pseudo BE-algebra. Moreover, we characterize different classes of generalized pseudo BE-algebras by some results.

In this paper we have introduced the concept of pseudo-metric which we induced from a pseudo-valuation on KU-algebras and investigated the relationship between pseudo-valuations and ideals of KU-algebras. Conditions for a real-valued function to be a pseudo-valuation on KU-algebras are provided.

Currently, the electro-hydraulic servo loading control system manufactured by MTS, OpenFresco hybrid test interface software and OpenSees finite element software are widely used in structure laboratories to carry out hybrid test, but there is no relevant public information about full structure pseudo-dynamic test based on the above software and hardware. In order to study the feasibility of using the above software and hardware to carry out full structure pseudo-dynamic test, the full structure pseudo-dynamic virtual experiments of a single degree of freedom (SDOF) structure and a two degrees of freedom (2DOFs) structure are carried out based on the MTS 793 Demo Mode, and the results are respectively compared with the finite element analysis method. The results show that the finite element analysis results and full structure pseudo-dynamic virtual experiment results are highly consistent, which verifies the feasibility of carrying out the full structure pseudo-dynamic test based on the above software and hardware. Then, a three story steel frame full structure pseudo-dynamic test is conducted, and the smooth implementation of full structure pseudo-dynamic test of the three story steel frame further verifies the reliability of thistesting method. The implementation method of carrying out the full structure pseudo-dynamic tests are introduced in detail, which can provide some reference for relevant research.

과학교등학교 학생을 대상으로 사이비과학에 대한 태도 학습 프로그램을 개발하기 위한 기초 연구로서 사이비과학에 대한 과학영재 학생들의 인식을 조사하였다. 이를 위해 먼저 초, 중, 고등학교에서 일반 학생과 과학영재아의 인식 차이를 조사하였다. 그 결과, 일반 학생에 비해서 과학 영재학생이 사이비과학에 대해 더 부정적인 사고를 가지고 있으나 학년이 올라가더라도 인식의 진전이 거의 없다는 것을 확인하였다. 다음으로는 6개월 동안 3번에 걸쳐 과학고등학교 학생들의 생각 변화를 조사하였는데, 이 조사를 통해 사이비과학에 대한 학생들의 생각이 견고하지 않으며 적절한 지도과정을 통해 합리적 논리적 사고를 하도록 유도하는 것이 가능할 것이라는 결론을 얻었다. 마지막으로 학생들의 사이비 과학에 대한 생각에 영향을 끼치는 요소를 조사하였다. 학생들의 사고 형성에는 TV나 서적과 같은 매체와 함께 개인의 경험이 큰 영향을 끼치는 것으로 드러났다. 따라서 매체에서 제공되는 정보의 진위를 판단하는 훈련이 필요하며 특히 점성술과 관련해서 학생들이 지속적으로 가졌던 긍정적 경험을 다시 돌아볼 수 있도록 유도하는 활동을 제공하여야한다는 결론을 얻었다.

Pseudo-ŁBCK-algebras are commutative pseudo-BCK-algebras with relative cancellation property. In the paper, we introduce fuzzy prime ideals in pseudo-ŁBCK-algebras and investigate some of their properties. We also give various characterizations of prime ideals and fuzzy prime ideals. Moreover, we present conditions for a pseudo-ŁBCKalgebra to be a pseudo-ŁBCK-chain.

Generalized pseudo-differential operators (PDO) involving fractional Fourier transform associate with the symbol a(x, y) whose derivatives satisfy certain growth condition is defined. The product of two generalized pseudo-differential operators is shown to be a generalized pseudo-differential operator.

In this paper, we correct some errors and typos of [2] and introduce a new concept related to pseudo n-Jordan homomorphisms, that we call it pseudo n-homomorphism. We investigate automatic continuity and positivity of pseudo n-homomorphisms and pseudo n-Jordan homomorphisms on Banach algebras and C*-algebras. Moreover, we show that the sum of two pseudo n-Jordan homomorphisms is not a pseudo n-Jordan homomorphism and we show that under some conditions the sum of two pseudo n-Jordan homomorphisms is a pseudo n-Jordan homomorphism.

수업 중 발화의 대부분을 차지하는 것은 교사의 발화이다. 그러나 교사는 항상 교사의 입장에서만 말하는 것이 아니라 학생 발화와 유사한 발화를 통해 학생들의 수업에 도움을 줄 수 있을 것으로 생각되나 이에 대한 연구는 아직 부족한 것이 현실이다. 따라서 본 논문에서는 이러한 발화 형태를 유사학생발화라 명명하고, 유사학생발화가 다수 관찰될 것으로 예상되는 방송 수업(EBS의 2005학년도 중 1 과학 수업 중 지구과학 부분)을 연구하여 유사학생발화를 '수업 중, 학생 발화와 같은 역할을 하나, 교사를 통해 이루어지는 모든 발화의 통칭'이라 정의하였으며, Lemke(1990)의 학생발화분류를 토대로 연구 대상인 수업 중 나타난 유사학생발화를 교사가 개입하는 형태의 유사학생발화와 교사가 개입하지 않는 유사학생발화로 크게 유사학생발화를 나누고 교사 개입 유사학생발화로 유사 교사-학생 간 협의(Pseudo Teacher-Student Conferences), 유사 삼단계 담화(Pseudo Triadic Dialogue), 유사 교재 활용 담화(Pseudo External Text Dialogue), 유사 학생 질문 담화(Pseudo Student-Questioning Dialogue), 유사 교사-학생 간 담화(Pseudo Teacher-Student Dialogue), 유사 교사-학생 간 토론(Pseudo Teacher-Student Debate), 유사 실 담화(Pseudo True Dialogue), 유사 학생 상호 담화(Pseudo Cross Dialogue), 유사 동료 학생 발화 (Pseudo classmate talk)를, 그리고 교사 미개입 유사학생발화로 유사 학생 독백/유사 수업 중 잡담(Pseudo student monologue/Pseudo side talk)을 분류하였다. 또한 이러한 분류와 함께 각 유사학생발화의 실례를 소개하고 그 특징을 기술하였다.

The purpose of this paper is to introduce a new class of rings that is closely related to the class of pseudo-Krull domains. Let 𝓗 = {R | R is a commutative ring and Nil(R) is a divided prime ideal of R}. Let R ∈ 𝓗 be a ring with total quotient ring T(R) and define 𝜙 : T(R) → R_Nil(R) by ${\phi}({\frac{a}{b}})={\frac{a}{b}}$ for any a ∈ R and any regular element b of R. Then 𝜙 is a ring homomorphism from T(R) into R_Nil(R) and 𝜙 restricted to R is also a ring homomorphism from R into R_Nil(R) given by ${\phi}(x)={\frac{x}{1}}$ for every x ∈ R. We say that R is a 𝜙-pseudo-Krull ring if 𝜙(R) = ∩ R_i, where each R_i is a nonnil-Noetherian 𝜙-pseudo valuation overring of 𝜙(R) and for every non-nilpotent element x ∈ R, 𝜙(x) is a unit in all but finitely many R_i. We show that the theories of 𝜙-pseudo Krull rings resemble those of pseudo-Krull domains.
