We study some properties of intuitionistic fuzzy normal subgroups of a group. In particular, we obtain two characterizations of intuitionistic fuzzy normal subgroups. Moreover, we introduce the concept of an intuitionistic fuzzy coset and obtain several results which are analogs of some basic theorems of group theory.

Let A and B be some standard operator algebras on complex Banach spaces X and Y, respectively. We give the concrete forms of linear idempotence preserving maps $\Phi\;:\;A\;{\rightarrow}\;B$ on finite-rank operators.

본 본문에서는 수학 기초학력이 부진한 P대학 입학예정자들의 문제해결력 향상을 위해 겨울방학을 이용하여 개설한 기초수학 특강을 수준별로 학급을 편성하여 운영하고, 그 결과를 토대로 효율적 기초수학 학습지도 방안과 수준별 학급운영에 대한 유의점 및 그 개선방안에 대해 알아보고자 한다. 연구 대상 학생들을 대상으로 학생실태 설문조사와 수학 기초학력 진단평가를 실시하고, 진단평가 성적에 따라 수준별 학급을 편성하여, 각 학급에 조교를 배정하여 대학생활에 대한 안내, 문제풀이 및 컴퓨터 활용학습을 지도하도록 하였다. 또한, 기초수학 수준별 학습지도를 위해 작성한 표준지침서에 의거하여 차별화된 수준별 수업을 진행한 후, 학업성취에 미치는 효과를 분석하여 보다 효율적인 기초수학 학습지도 방안을 찾아보고자 하였다.

We are presented of several basic properties for negatively superadditive dependent(NSD) random variables. By using this concept we are obtained complete convergence for maximum partial sums of rowwise NSD random variables. These results obtained in this paper generalize a corresponding ones for independent random variables and negatively associated random variables.

In this paper, we introduce the concept of derivative of the function f : $\mathbb{Q}p{\to} R$ where $\mathbb{Q}p$ is the field of the p-adic numbers and R is the set of real numbers. And some basic theorems on derivatives are given.

This paper presents a parallel implementation of stiff-ness matrix calculation based on the processor farm model on a net-work of workstations running PVM programming environment. As the computational characteristics of stiffnes matrix exhibits good po-tentials for effective prallel computation the performance improve-ment is show to be almost linear with the number of sorkstations involved in the computation.
