네오비움 페롭스카이트 ( Ca2NbFe3+O6 ) 의 화학조성 및 리트벨트 구조분석 연구
최진범(Jin Beom Choi),(Frank C. Hawthorne) 한국광물학회 2002 광물과 암석 (J.Miner.Soc.Korea) Vol.15 No.1
Chemical analyses and Rietveld structural refinement with powder X-ray diffraction data were done for Nb-rich perovskite, named latrappite (Ca_2NbFe^3+O_6) from the Oka, Quebec, Canada. Latrappite is shown to be a member of a continuous solid solution of CaTiO_3-NaNbO_3-Ca_2NbFe^3+O_6, and approximately ((Ca_1.5Na_0.4) (Nb_1.0Ti_0.6Fe_0.4)O_6 in composition. The crystal structure of latrappite, determined by Rietveld refinement, is similar to that of perovskite (CaTiO_3). It differs in that replacement of Ti by Nb and Fe^3+ results in greeter distortion and tilting of the TiO_6 framework octahedra relative to CaTiO_3 Revised unit-cell parameters of latrappite are a=5.4474(4), b=5.5264(4), c=7.7519(5) A°, V=233.4(3) A°^3, space group Pbnm.
D. H. Lawrence의 시에 나타난 탈근대성 연구
최진범 ( Choi¸ Jin-beom ) 동국대학교 영어권문화연구소 2009 영어권문화연구 Vol.2 No.1
This article aims to analyze the trans-modernity in D. H. Lawrence's poetry, exploring the authentic vitality of the human state in his poem. The early of 20th century including the time of Lawrence lifetimes and literary working activities was the period of riding on a Western modernity. At that time, the idea of modernity was the assertion with the centre of the Western, the white, and the male-centered. The West conceived modernity as a Reason so it sweeps away any idea and organization which are not based upon rationalization. In contrast, Lawrence had went over the other side of the idea of the Western modernity that it formulated. He tried to overcome the idea of western modernity. His attitude like this does provide a model for ecology, vitalism and a temporal view of trans-modernity. And the idea is replaced by followings ; To begin with, the main spot is the thought of ecology and pantheism in his anti-religious poems. In general God is a symbol of brightness but Lawrence attempted to find out the “God in Darkness” in natural beings. The power of the dark is itself a urge and desire of becoming, which it takes the immanent. Its' attitude is very close connection to the idea of ecological epistemology. Secondly, we can identify the vitalistic aspect in his animal-poems. The poet describes the becoming animal through a series of his animal-poems criticizing the domination over a natural beings. It is asserted that the divorce between natural beings including animal and human is the very dichotomy in the Western modernity, arguing against the bioppositionary itself. Finally, we need to pay attention the temporal view of trans-modernity in his latter poems. In his last poem he had been written with the subject of ‘death’ which was close related on ‘vitality.’ His belief, which the vitality can not be existed without ‘death’ and ‘oblivion’, shows the willingness to the continued desertion and becoming. This conviction is against the temporal view of the Western linear modernity and Christianity. This idea in his poem is not a simple repetition but a repetition in difference as taking the time of variation and becoming. From the perspective view, Lawrence searched for the possibility that gives rebirth to the vital being oppressed by the Western modernity. To do this, he tries to get over the poor condition of modernity at that time and replaces it to a new discourses involving a ecology, feminism, and decolonialism etc.
