  • In n-dimensional unified field theory(n-UFT), the reciprocal representations between the g-unified field tensor $g{\lambda}{\nu}$ and $^*g$-unified field tensor $^*g^{{\lambda}{\nu}}$ play essential role in the study of n-UFT. The purpose of the present paper is to obtain some reciprocal relations between g-unified field tensor and $^*g$-unified field tensor.

  • It is well known that the accurate calculation of the field distribution is essential for the design of electrical machines. The analytical techniques for electromagnetic field can quickly and exactly determine airgap magnetic field distribution in electrical machines. Many analytical techniques have been investigated to predict the magnetic field distribution in PM machines equipped with permanent magnets. Using the analytical technique by transfer relations, D. L. Trumper and K. R. Davey already presented the design and analysis of linear permanent-magnet machines and induction machines, respectively. Using the transfer relations (Melcher's general methodology) to describe electromagnetic phenomena, this paper deals with the analysis on the magnetic field distribution due to PM and winding current, the induced voltage and the static torque characteristics in surface-mounted slotless type permanent magnet machine. The validity of the analysis results is confirmed by finite element (FE) analysis.

  • This paper interrogates the theoretical foundations of Cross-Cultural Studies across the Social Sciences through an examination of the field ELT. Through an examination of ELT's major theoretical and pedagogical moves, this paper illustrates how ELT is by nature a field of cross-Cultural Studies. A closer examination of the history of ELT shows how the colonial genesis of the field indicates a skewed representation of power between native English speaking nations and non-native speaking nations both in terms of academic theories and pedagogies, as well as socio-cultural relations of power. A further analysis of how the field theorizes and represents various relations of power between disparate cultures in ELT literature explicates the dilemma of the objectivity and neutrality of Cross-Cultural research in ELT. In doing so, the analyses included in this paper thus necessarily raises questions regarding the theoretical foundations of research methodologies of Cross-Cultural Studies in terms of the reflexivity of researchers and the problematic of how, or if, relations of power are included in the studies. This paper questions whether studies that do not include these research perspectives properly represent the disparate cultures under study, or are more of a biased, or Orientalized (Said, 1979) interpretation of cultures.

An English School of International Relations Approach to Public Diplomacy: A Public Diplomacy Framework for Global Governance Issues

  • Throughout the six decades evolution of the public diplomacy concept, international relations approaches have remained at the margins of the field. An important international relations theory that has been virtually non-existent in the public diplomacy literature is the English School of international relations. This theory has been the centerpiece of literature in diplomatic studies, but curiously, has not been applied to public diplomacy. In this editorial, I outline a public diplomacy framework for global governance issues that builds on the English School and Pamment's framework on the intersection of international development and public diplomacy.

  • The year 1997 was when Korean Journal of Public Relations Research started to publish research articles. This study addresses the issue of theories in Korean public relations research. A total of 166 research papers are analyzed to see characteristics and changes during 2003-2012. Through this meta analysis, the researcher tries to see the big picture and discusses the right direction for the future of the public relations in many ways. Three different groupings were adopted to classify theories in the 10 year perion - 1. origins of theories(public relations field, related neighbor field, distant field), 2. target of analysis(individual, organization, society), 3. level of approach (systematic pluralistic, rhetorical, critical approach). According to the findings, though getting better, it was 'cold season' in public relations research because theories utilized in Korean public relations research were not very excellent qualitatively and qualitatively. Interdisciplinary approach is discussed.

  • Lower dimensional cases of Einstein's connection were already investigated by many authors for n = 2, 3, 4, 5, 6, 7. This paper is the first part of the following series of two papers, in which we obtain a surveyable tensorial representation of 8-dimensional Einstein's connection in terms of the unified field tensor, with main emphasis on the derivation of powerful and useful recurrence relations which hold in 8-dimensional Einstein's unified field theory(i.e., 8-g-UFT): I. The recurrence relations in 8-g-UFT II. The Einstein's connection in 8-g-UFT All considerations in these papers are restricted to the second class only, since the case of the first class are done in [1], [2] and the case of the third class, the simplest case, was already studied by many authors.

Experiment on the Anomalous Animal Behaviors by Electric Field Effects for detecting Earthquake Precursors (지진전조현상 파악을 위한 전기장 효과에 의한 동물 이상 행동 실험)

  • There are some previous reports that some animals such as rats and birds move in a large group and act abnormally to avoid the large earthquake. This study is to experimentally testify what relations exist between the anomalous animal behavior and electric field effect, which is reported due to the piezoelectric effects in a basement rock before earthquake occurrences. When electric field is applied to the whole bottom of the cage, they show nervous behaviors such as grooming, washing their faces, standing on legs or running around in panic to avoid the electric field. When more strong electric field is applied, they jump with shrieking and mount on the electric line. The rat shows more sensitive anomalous behavior than the bird. Even though the current to the experimental birds and rats is just a few $\mu$A, they react in various ways. The anomalous animal behaviors under the small ground electric field may have some relations to the actual phenomena before great earthquake. This kind of study is quite worthy for the understanding of earthquake precursors.
