Junior college students in located Eup-Myeon areas commonly fail to meet the basic standards of mathematics. This leads students to lack basic knowledge and to have difficulties in studying their majors. In addition, students often lose their interest in the study and eventually leave school or drop out, while some have difficulties in their life at work. To remedy and solve these problems, the country proposes National Competency Standards(NCS). The basic occupational competencies proposed in NCS are essential occupational abilities required to successfully perform the job. I want to apply mathematical ability, which is one of the basic occupational competencies, to mathematics education of junior college. Applying NCS mathematical ability to junior college students, I would like to examine the effectiveness of the NCS mathematical ability course. The purpose of this study is to find out the way of education of desirable mathematical ability and to raise basic academic ability and interest in mathematics.

In D university, 2010 year engineering freshmen were taken basic mathematical ability test and were given basic mathematical ability improvement program based on the test. In order to study the effect of this program for scholastic achievement, we analyse basic mathematical ability test score and college mathematics score among student groups. And to study the effect of this program for scholastic motivation, we survey the mathematical inclination, the recognition of mathematics, and classes of mathematics. As results, engineering freshmen in D university were poor at basic mathematical ability and basic mathematical ability improvement program effected scholastic achievement and motivation in mathematics, greatly. For the success of college mathematics in engineering college, this study suggests basic mathematical ability test and the survey for engineering freshmen's mathematical background. Finally, we suggest that college mathematics must be focused on the improvement of basic mathematical abilities.

We in this paper obtained the theoretical results for multivariate stochastic processes which help us to extended negatively orthant dependent(ENOD) structures among hitting times of the processes. In addition, some applications are given to illustrate these concepts.

Giuliano Antonini et al.(2008) have introduced the concept of extended acceptability and the results show that the extended acceptability structure has no effect on the exponential inequality except replacing a constant M = 1 with a constant M > 0. We discuss the complete convergence for extended acceptable random variables by using the exponential inequality.

In this paper, we present a new extended Jacobi method for computing eigenvalues and eigenvectors of Hermitian matrices which does not use any complex arithmetics. This method can be readily applied to skew-Hermitian and real skew-symmetric matrices as well. An example illustrating its computational efficiency is given.

We introduce the notions of intuitionistic fuzzy prime ideals, intuitionistic fuzzy completely prime ideals and intuitionistic fuzzy weakly completely prime ideals. And we give a characterization of intuitionistic fuzzy ideals and establish relationships between intuitionistic fuzzy completely prime ideals and intuitionistic fuzzy weakly completely prime ideals.

We study a new ring property called axis-commutativity. Axis-commutative rings are seated between commutative rings and duo rings and are a generalization of division rings. We investigate the basic structure and several extensions of axis-commutative rings.
