This study examined the concept and essence of archetype theories of Johann Wolfgang von Goethe, Rudolf Steiner and Carl Gustav Jung, which theatrically influenced Michael Chekhov. It analyzed how archetype theories were applied in Chekhov's Psychological Gesture and tried to fundamentally understand Chekhov's Psychological Gesture that embraced archetype theories. The concept of archetype repeatedly appears in Chekhov's Psychological Gesture. Chekhov stated that archetype exists in the inner psychology or instinct of the actors and he defined the Psychological Gesture as an archetypal gesture. While exploring references regarding archetype in Chekhov's Psychological Gesture, this study found that it is closely related to archetype theories. Therefore this study thoroughly analyzed Goethe's archetype theory(archetypal plant), Steiner's archetype theory(4 temperament archetypes, 7 human's soul archetypes), Jung's archetype theory(collective unconscious and 4 archetypes, 12 personality archetypes) and it confirmed that archetype theories had a significant influence on Chekhov's Archetype Theory and Psychological Gesture. Goethe and Steiner's archetype theories, Eurythmy are applied to theater education and actor's acting. Likewise, Jung's archetype theory is also adopted theatrical studies and theatrical psychotherapy. The author believes that Chekhov's Archetype Theory and Psychological Gesture influenced by archetype theories will significantly help an actor analyze characters in the play and portray them in creative acting.

In this paper, we analyzed a two-branch polarization diversity at a mobile station in NLOS environment when a base station transmits a circularly polarized wave. In order to calculate the correlation coefficient considering the XPD(cross polarization discrimination) between the received signals for the two diversity branches, a simple theoretical model of circular polarization diversity is adopted. From the analysis results, it can be seen that the XPD of circularly polarized wave is less than vertically polarized wave about 6~7 dB in measurement results. And also, it is clearly seen that the correlation coefficient of circular polarization diversity evaluated by the XPD is less than that of vertical polarization diversity.

권 등(2008)은 수면보다 높은 정방형 다열기둥을 이용한 수리실험을 수행하여 수심과 이격거리에 따른 상당저항계수를 측정하였으며 이를 바탕으로 Manning 계수형태의 상당저항계수 이론식을 제안하였다. 본 연구는 수면보다 높은 원형 다열기둥을 이용한 수리실험을 수행하여 이격거리와 수심에 따른 상당저항계수를 측정하였다. 실험결과로부터 이격거리만의 함수로 가정한 항력상 호작용계수를 추정하여 이를 권 등(2008)의 이론식에 적용하여 실험결과와 비교하고 분석하였다. 정방형 다열기둥의 실험결과와 원형 다열기둥의 실험결과를 비교하여 흐름방향 이격거리가 큰 범위에서는 원형기둥의 저항계수가 정방형기둥의 저항계수보다 작게 측정되지만 흐름방향 이격거리가 감소할수록 원형기둥의 저항계수가 정방형기둥의 저항계수보다 증가하면서 원형기둥이 정방형 기둥보다 저항정도가 큰 상태가 되는 것을 알 수 있었다.

This paper presents the basic characteristics of a 5 element dipole array antenna which has a four parastic element and one driving element at the center of the circular array. The coupled integral equations for the unknown current distributions on dipole elements are derived and solved by applying Galerkin's method of moments. The numerical results show that the highest power gain of 7.8 dBi is obtained at radius of d = 0.3lλ when two short circuited parastic element neighbors. In order to verify the theoretical analysis, the radiation pattern is compared with Preston's results.

A new type of circularly polarized(CP) antenna that is characterized by having both low-profile and greater axial-ratio bandwidth(ARBW) beyond existing antennas is introduced through analysis of artificial magnetic conductor(AMC) polarizer, and experimentally demonstrated. Although it is made use of a linear-polarized dipole antenna with close proximity to ground plane, it is backed by AMC polarizer so as to efficiently radiate with circularly changed polarization whose ARBW is determined by the texture geometry, whereas existing antennas exhibit CP surface-current on radiators, which limit ARBW. The mechanism of the polarization conversion is theoretically analyzed for ARBW, and the experimental properties including the impedance matching, CP radiation pattern, axial-ratio pattern, ARBW, and two-port isolation are discussed.

The circular composite tubes have been used as a main spar of HALE-UAV(High Altitude Long Endurance-Unmanned Air Vehicle). In this paper, an analytical model is presented for the prediction of the failure load of unsymmetrically stiffened circular spar using a modified Brazier approach. This model was used to predict the moment carrying capacity of the unsymmetrically stiffened circular spar. From the results, we can know that a stiffened cap placed in the top sector of a spar increased the bending capabilities. Four point bending tests were conducted to estimate the effect of the cap on the failure load and compared with the proposed model. And numerical simulations were performed to analyze the behavior of stiffened circular spar. Comparisons of the results from the proposed model with those from experiments and numerical modes show good correlation.

In some binary solution, closed miscibility loop of temperature-composition phase diagram occurs where both an upper critical solution temperature and a lower critical solution temperature exist. It is known that this phenomena occurs if specific interaction between molecules exists. There are several ways describing the specific interaction. In this work it is assumed that the total number of specific interactions is distributed according to binomial distribution. In this case, exact mathematical conditions for closed miscibility loop phase behavior are derived when the specific interaction is applied to regular solution theory, quasichemical theory and Flory-Huggins lattice theory. And we investigated the effect of parameters on the phase diagram. The phase diagram of water-nicotine is calculated and compared with experimental data.

In this paper, we propose to understand the conceptual structure of programming elements that learners form during the prototyping theory. To do this, we reviewed previous studies on the meaning of conception and prototype theory and conducted a course of problem-solving programming for 33 university students who had no prior experience in programming, and collected transcription materials through conceptual metaphorical writing. The conclusions of this study are as follows: 1) Identifying the conceptual structure of learners as a conceptual metaphor can enhance the effectiveness of programming education. 2) Learners need to reinforce the experience of forming abstract attributes to form mature programming concepts. 3) The concept of programming differs in the structure of multi-level concepts that students, teachers, and professional programmers have in each group. 4) Programming elements should intentionally block misconception risks in the meaning of symbols. 5) Concept evaluation tools should be developed to check whether various attributes can be applied.

The study aims to examine the connection between psychology in human unconsciousness and color, after looking at the meaning and symbolism of the characteristics and colors in Klimt's paintings from an analytical psychological point of view, Gustaf Jung's archetype theory. After analyzing Jung's archetype theory, First, in Klimt's paintings, the gold and yellow colorful decorations and patterns expressed desire with unconsciousness, sex, and especially a woman's desire for sex. The physical relationship between men and women is described as eros, life, and death. Second, the main colors in the paintings were blue, black green, gold, yellow, and orange, indicating anger and oppression, passion, desire, hope, and eroticism, and orange and yellow colors represented the inner healing colors of hope. Third, the artist's inner healing process contains color for himself and incorporates the inner unconsciousness and consciousness. The colors expressed in paintings are not only therapeutic meaning but also being conscious of inner unconsciousness, which is valuable as healing. Therefore, the color will be useful as a means of conveying psychological expression in the psychological counseling sessions.
