In this paper we give some conditions under which the Weyl spectrum of an operator satisfies the spectral mapping theorem for analytic functions. Also we show that Weyl's theorem holds for p(T) where T is an operator of M-power class (N) and p is a polynomial on a neighborhood of $\sigam(T)$. Finally we answer an old question of Oberai.

We discuss the integrability of orthogonal almost complex structures on Riemannian products of even-dimensional round spheres and give a partial answer to the question raised by E. Calabi concerning the existence of complex structures on a product manifold of a round 2-sphere and of a round 4-sphere.

A domain is called an LPI domain if every locally principal ideal is invertible. It is proved in this note that if D is a LPI domain, then D[X] is also an LPI domain. This fact gives a positive answer to an open question put forward by D. D. Anderson and M. Zafrullah.

In this paper, we introduce the concept of statistically sequentially quotient map which is a generalization of sequence covering map and discuss the relation with covering maps by some examples. Using this concept, we give an affirmative answer for a question by Fucai Lin and Shou Lin.

Literacy-related communication and information types naturally occurring in the dramatic play area were observed during free play over a 4 week period. Participants were 21 boys and 16 girls enrolled in a kindergarten class in Taegu. Types of literacy-related communication frequently used during social pretend play were Description, Suggestion, Question, and Answer. Negative types of literacy-related communication, such as Threat, Protest, and Warning were rare. Types of frequently occurring literacy information were about letters & words, and literacy functions. These findings were discussed with respect to curricular implications for the classroom.

This paper is planned to use randomized response technique which is an indirect response technique on internet as a way of obtaining much more precise information, not revealing secrets of responsors, considering that respondents are generally reluctant to answer in a survey to get sensitive information targeting employees, customers, etc.

The purpose of this study is to find out the answer to the Question as "What is the meaning of the Science Education?". Semantic analyses were done according to each situations and contexts in science, education and science education. The following result was drawn: It is concluded that science education is the practtical behavior for the human as the purpose, through the science and education as the means and methods.
