Photoluminescence (PL) and alternating-current electroluminescence (EL) of manganese-activated zinc gallate (ZnGa2O4:Mn) thin films prepared by sputtering have been investigated. X-ray diffraction measurements indicated that the ZnGa2O4:Mn films possessed a cubic spinel polycrystalline structure with a random crystallographic orientation of grains. Atomic force microscopy observation revealed that the films had a granular-shaped surface morphology with nanometer-sized grains uniformly distributed over the film surface. The ZnGa2O4:Mn films showed a PL emission peaked at around 506 nm in the green range, which characteristically originates from the intrashell transition of 3$d^{5}$ electrons in Mn2+ ions from the 4T1 excited-state level to the 6A1 ground state. Half-stack alternating-current thin-film electroluminescent (ACTFEL) devices were constructed using an inverted single-insulating structure, which consisted of indium tin oxide, ZnGa2O4:Mn, barium titanate and aluminum. The fabricated ACTFEL devices exhibited a broad and intense emission band with a maximum at about 508 nm and the peak shape was similar to that observed from the PL emission. The EL emission had CIE color coordinates of x = 0.114 and y = 0.70, indicative of good chromaticity for a green-emitting ACTFEL display phosphor layer.

The structure and the properties of gallium nitride (GaN) thin films prepared by using a radiofrequency (RF) magnetron sputtering method are reported. The GaN thin films were deposited on p-type (111)-oriented silicon substrates at room temperature in a pure nitrogen atmosphere. X-ray photoelectron spectra showed that the films were mainly composed of gallium and nitrogen. An oxygen impurity was found to be incorporated into the films during the deposition. The refractive index of the GaN films was measured to be 2.36 at a wavelength of 633 nm. The optical bandgap of the GaN films was determined to be approximately 3.31 eV. From the grazing incidence X-ray reflectivity measurements, the density and the surface roughness of the GaN films were estimated to be 5.827 g/cm<sup>3</sup> and 2.95 nm, respectively. The X-ray diffraction analysis revealed that the crystalline phase of the GaN films changed from wurtzite to zinc-blende as the working gas pressure was reduced. The observed phase change was found to be independent of the orientation of the Si substrate, but to be strongly correlated with the biaxial compressive stress.

Alternating-current thin-film electroluminescent (ACTFEL) display devices fabricated using manganese-doped zinc germanate (Zn2GeO4:Mn) as a green-emitting electroluminescent layer material are described. The ACTFEL display devices were fabricated with a standard bottom emission structure having a multilayer stack of thin films in the metal/semiconductor/insulator/ metal (MSIM) configuration. The device was constructed on a transparent Corning glass substrate through which the emitted EL light passed. The Zn2GeO4:Mn emission layer was synthesized by using a RF magnetron sputter deposition method, followed by post-annealing at 700 C in air ambient for 1 hour. The obtained Zn2GeO4:Mn films were found to be polycrystalline with a rhombohedral crystal structure. A green emission spectrum with a maximum at approximately 538 nm was produced from the fabricated device. The chromaticity color coordinates of the EL emission were measured to be x = 0.308 and y = 0.657. The device demonstrated a sharp increase in the intensity of green EL emission upon increasing the AC peak voltage applied to the device above a threshold of 148 V.

The purpose of this study is to investigate the effects of hotel employees’ leisure activity participation on organizational commitment and customer orientation. The summary of the result from this investigation is as follows. First, the study found that educational and social activity among 4 factors of intra-company club activity have affected on organizational commitment. Second, the study found that only the social activity among 4 factors of intra-company club activity have affected on customer orientation. Third, the study found that emotional commitment, continual commitment, normative commitment, the 3 factors of organizational commitment, have affected on customer orientation. This study shows that the participation of intra-company leisure activities of hotel employees has a positive effect on the organizational commitment and the quality of customer-oriented service. Therefore, the company is suggested developing and supporting effort for leisure activity programs like intra-company club activities in order to maximize satisfaction of employees.
Creative Dialogue on Ultimate Reality
김주한 한국민중신학회 2010 Madang: Journal of Contextual Theology Vol.0 No.13
The purpose of this paper is an attempt to make creative dialogue in Korean society where there are intermingles of various religions. In order to carry out this task, I will employ John Hick’s pluralistic hypothesis. I argue that before entering into interreligious dialogue, we should examine the nature of Ultimate Reality. On the agreed understanding of the Ultimate Reality, I am sure, we can make creative dialogue. I will try to make point of contact of Christian God to the concept of Hannim, the expression of the Ultimate Reality experienced and perceived in the Korean traditional religious-cultural context. The paper demonstrates that whether such revision of ‘theo-logy’ is possible in the cultural and spiritual setting of Korea. Here the work of Hick is supported and supplemented by suggesting that Hannim would be a different manifestation of the Real. Consequently, this paper states that each religion, and more specifically each religious community, must e faced on its own distinctive terms and within its immediate cultural environment.
