The purpose was to compare the ethical knowledge, values and class satisfaction by students' cognitive style to develop the convergent nursing ethic class considering cognitive style. Questionnaires were collected from 149 freshmen after 12 hours classes for four weeks from October 1st to 30th 2013. Group Embedded Figure Test was used as a cognitive style measurement tool. 62.4% of them were field-dependent. There was a significant difference in cognitive style and ethical knowledge according to high school division. The ethical value was different significantly according to the nursing science satisfaction. Class satisfaction was different significantly according to reason for applying to nursing and nursing science satisfaction. There were no significant differences in ethical knowledge and values by cognitive style. Class satisfaction was higher in field-dependent students. This conclusion will give baseline data to develop nursing education program based on cognitive style.

The spatial separation of male's and female's area due to the law of 'Naeoei' is one of the trademark features of residence by the building principle of 'Confucianism' in the upper class house in the late of the Chosun Dynasty. Thanks to modernized agriculture and commerce, the residence of 'Sinheung-Yangban' developed. And they were influenced by the economic and living characteristics than traditional custom. So the residence of 'Sinheung-Yangban' is very important in terms of the course of modernizing of the korean traditional residence. Researcher figures out the influences of the law of 'Naeoei' in residence and the characteristics of male's and female's field in terms of daily life with investigating the residence of 'Sinheung-Yangban' as the upper class house in the late of the Chosun Dynasty. Through this, the goal of this study is to find the properties of male's and female's field of upper class houses in the late of the Chosun Dynasty. With this study, the followings are the characteristics of male's and female's spatial composition of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. First, the traditional law of 'Naeoei' plays a primary role as the principle of building of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. With a natural result, there is a clear spatial separation as the male's and female's social role. Second, 'An-Chae' and 'Sarang-Chae' as male's and female's living space are separated physically, but real living life tends to be syntagmatically made with 'An-Madang' as the center. Third, spatial integration of 'An-Madang' as the center results in the development of architectural connection factors of 'An-Chae' and 'BaKat-Chae' adjoining 'An-Madang', facing 'Toei-Gan', 'Maru', and 'door'. Forth, the boundary of male's and female's areas is relatively clear between dwellers and visitors, but on the other hand, the separation of male's and female's spaces between family members has little significance.

We obtained some class fields associated to an order R of a function field and evaluated the valuation of the invariant $\xi (c)$ for an invertible ideal c of R.

In the previous paper [8], the author gave a determinant formula of relative zeta function for cyclotomic function fields. Our purpose of this paper is to extend this result for more general function fields. As an application of our formula, we will give determinant formulas of class numbers for constant field extensions.

In this paper we study of densities of the 4-rank of narrow ideal class groups of real quadratic function fields over the rational function field $\mathbb{F}_q(T)$ when $q{\equiv}3$ mod 4.

The purpose of this study is to examine the efforts of cooperative loaming through a student team-achievement division(STAD) model on elementary school students' learning achievements and science ,elated attitudes toward the field of astronomy. This study was conducted using 72 students of the fifth-grade class in a elementary school in Busan. The 18 science lessons of the 'Family of the sun' were executed over 6 weeks in the fifth-year students classes. In this study, the experimental group were exposed to cooperative learning through STAD and the contrast group were exposed to a traditional teacher-centered class. The results show that the STAD class of the experimental group had a greater effect upon the elementary school students' science learning achievement and science related attitudes toward the field of astronomy than those of the comparison group. Additionally, the students recognized that cooperative learning provokes both interest in loaming and in their studies generally and also they expressed a desire to continue with cooperative teaming methods.

Currently, vocational high schools are trying to learn through project learning and similar courses. This is to nurture talented students who can be directly involved in the industrial field. In this study, we modified the existing ADDIE model, designed the model for the class, and operated the actual augmented reality programming class to verify the validity. As a result of the operation, the learners' satisfaction and achievement were high, and the ability to solve the problem was improved as it was developed in the actual field. In this study, it is meaningful to develop a teaching model closely related to the field through the project learning using the augmented reality programming.

We examine fundamental units of quadratic function fields from continued fraction of $\sqrt{D}$. As a consequence, we give another proof of geometric analog of Ankeny-Artin-Chowla-Mordell conjecture and bounds for class number, and study real quadratic function fields of minimal type with quasi-period 4.

We generate ring class fields of imaginary quadratic fields in terms of the special values of certain eta-quotients, which are related to the relative norms of Siegel-Ramachandra invariants. These give us minimal polynomials with relatively small coefficients from which we are able to solve certain quadratic Diophantine equations concerning non-convenient numbers.

Let G be a finite group with k distinct conjugacy classes $C_1, C_2, \cdots, C_k$ and F an algebraically closed field such that char$(F){\dag}\left$\mid$ G \right$\mid$$. We denoted by $Irr_F$(G) the set of all irreducible F-characters of G and $Cf_F$(G) the set of all class functions of G into F. Then $Cf_F$(G) is a commutative F-algebra with an F-basis $Irr_F(G) = {\chi_1, \chi_2, \cdots, \chi_k}$.
