This paper tried a detailed approach to identify the correlation among basic elements that influenced the change of forms of the Po. To this end, the subjects were limited to the clothing from the 15th to the 18th century, which was found in the tombs of the period of Pyeonbokpo. The total number of excavated artifacts measured directly is 6 and other correctly described excavated artifacts for a total of 54 items. Per period and element, the types of collars and Seop were presented by classifying collars in 4 types, and Seop in 3 types. On the basis of the classification, the relics selected in this paper were analyzed considering the appearance, period, and rate per type of each element. The type and the change of forms of each element per period, with the focus on the appearance, were identified and the factors influencing the change of forms per element and the correlation between such factors were investigated. The representative type in the first period included dual collars, dual Seop and the representative type in the second period was characterized by a shawl collar and a dual Seop joining the pieces. The representative type in the third period was characterized by round collars and a short Seop. The elements determining the forms of Po, including collars and Seop, had a correlation to the lapse of time and had been systematically influencing each other. Furthermore, the overall change of form was caused due to the social functions as well as the supplementary function of keeping balance among the elements and accordingly, the change of forms was think characterized per period.

This study is to discuss on intrinsic justification of 'citizenship' and 'spaces of citizenship' to inquiry possibility of citizenship education through geography subject. According to Peters' educational view as forms of knowledge and initiation, citizenship was intrinsically justified through examination of forms of geographical knowledge. The analysis of paradigms in geography shows that 'the human' and 'the social' are generally combined in 'space'-centered language and ideologies through post-positivism. That is, it refuses the concept of physical space which is value neutral, and seeks turn to spaces of citizenship which is value-intrinsic through social space theory. Given that changes in the forms of geographical knowledge lead changes in content knowledge of geography subject, citizenship is to be justified intrinsically. Thus, citizenship as content knowledge of geography subject is to be justified not extrinsically through acceptance of social studies' educational aim in itself but intrinsically through forms of geographical knowledge. And geographical education as initiation into value and belief of citizenship based on these spaces of citizenship is not about making students have arrived at a destination, but about them travel with a different view.

Ten years have passed since Korea began its movement of modernization of mathematics education. In that period, there have been many studies for the movement. But most of the studies were those of curriculum. But the topic of this report reveals that the modernization of mathematics education in Korea depends on the frontiership, the deliberate studies of materials and the improvement of teaching forms in class.

Orbital interactions of the types, ${\sigma}-{\pi},\;{\sigma}^*-{\pi},\;{\sigma}-{\pi}^*\;and\;{\sigma}^*-{\pi}^*$ are investigated for the rotamers of ${\alpha}$-X-acetones (X = F and Cl) using STO-3G method of calculation. It was found that the interactions are possible only in gauche forms, and the ${\sigma}^*-{\pi}^*$ interactions are in general greater than the $\sigma-\pi$ interactions due to the greater overlap, in spite of the greater energy gap involved; the greater ${\sigma}^*-{\pi}^*$ interaction causes greater lowering of ${\pi}^*$ level relative to the lowering of ${\sigma}$ in the ${\sigma}-{\pi}$ interaction so that both ${\sigma}-{\pi}^*$ and $n-{\pi}^*$ interactions are enhanced in the gauche forms. The extra stability of the gauche form and the red shift in the $n-{\pi}^*$ transition are thus found to be natural corollaries of the greater ${\sigma}^*-{\pi}^*$ interaction in the gauche forms.

This study explored social media use among 50 adolescents attending a public high school in a non-Western community. Adolescents participated in focus group interviews and completed a written self-report survey. Findings revealed that these teenagers use electronic communication forms such as phone texting and social networking sites to connect with friends and family. They show a preference for Facebook, YouTube, and Instagram, do not engage in risky Internet behavior, and acknowledge both positive and negative aspects of electronic communication forms. In addition, their selection of electronic communication forms is dependent upon several factors that include the strength of the relationship and type of discourse exchange. For example, they reserve phone texting and cell use, which are more private communication mediums for family and friends. Electronic communication did not replace face-to-face interactions; rather it complemented and extended those interactions. Findings support existing literature on adolescent social media use and those shared with other collectivist cultural groups.

By constructing a canonical basis for the space $M_k^{\sharp}({\Gamma}_0(N))$ explicitly, we find a basis of the space of cusp forms for ${\Gamma}_0(N)$ consisting of $Poincar{\acute{e}}$ series.

We find congruences for the t-expansion coefficients of a Drinfeld modular form for ${\Gamma}^+_0$(Q), where Q is a monic irreducible polynomial. As an application we obtain new congruence relations for the t-expansion coefficients of Drinfeld modular forms for ${GL_2}(\mathbb{F}_q[T])$.
