There has been a growing sense of a new spirituality today. This new wave of interest in finding an alternative spirituality indicates that the ends of definite progress and prosperity, which modern spirituality has promised to us, is an unrealistic and, at best, unsustainable goal for our biotic community. Ironically, this hoped-for techno-centric utopia of unlimited expansion instead now leads to the fear of humanity about the possible mass destruction of the earth community. Recognizing the seriousness and urgency of the ecological crisis, this paper first finds the root cause of the global disaster in the religious and cultural ideology of modern spirituality. It then searches for an alternative spirituality as a solution to this crisis, that is, ecofeminist spirituality. In opposition to the patriarchal spirituality which justified social systems of domination, ecofeminist spirituality suggests an earth-based egalitarian spirituality. To this end, this paper examines the need for a new spirituality as a way to discover and overcome the interconnected nature of the various forms of oppression of women and nature. It further examines the background and development of ecofeminist spirituality as combining the spiritualities of women, nature and the oppressed. In the end, this paper reconstructs major concepts of ecofeminist spirituality such as the universal wel-being of creation, theology of embodiment, the interconnectedness of all forms of life, the transience and value of humanity, human responsibility and care for creation.

In this study, the effect of ionic liquid cation on the long-term stability of membranes was investigated using 1-methyl-3-octylimidazolium tetrafluoroborate (MOIM+BF4 -). The initial permeance of the poly(ethylene oxide) (PEO)/AgBF4/MOIM+BF4 - membrane was 17 gas permeation unit (GPU), but after 100 hours of gas permeation experiment, it showed a low permeance of 5.3 GPU. Uv-vis spectra also showed that MOIM+BF4 - could not prevent aggregation of silver nanoparticles. This indicated that the MOIM+BF4 - in the membrane could not stabilize the silver nanoparticles and thus the silver nanoparticles were aggregated and acted as a gas permeation barrier. MOIM+BF4 - could not stabilize the surface of silver nanoparticles because of the long chain length of the cation. This indicated that the cation of the ionic liquid, especially carbon length, was main factor affecting the stability of separation performance with time for polymer/silver salt/ionic liquid complex membranes.
The Ecological Epistemology of Pulyon Kiyon and its Ethical Implication in Tonghak
전현식 한국기독교학회 2005 한국기독교신학논총 Vol.39 No.-
This paper attempts to develop Tonghak ecological epistemology and its ethical implications for dealing with the ecological crisis. I first address Tonghak ecological epistemology of Pulyn Kiyn (the paradoxical logic of the cosmic life) as an alternative to the Western dualistic view of reality. I also develop Si Ch’nju ecological ethics, especially in Kagji Puli as ecological justice which is the ethical implications of Si Ch’nju spirituality, that is, Naeyu Silryng and Oeyu Kihwa. And then I attempt to show the vision of eco-justice, which the Tonghak ecological ethic seeks in the ecological community of Huch’n Kaebyk where I affirm humanity’s conscious, responsible and yet humble participation in the global biotic community.
시금치에서 분리한 광계 2 복합체의 불활성화와 재활성화에 대한 연구

Inactivation and reactivation of photosynthetic oxygen evolving complex were studied with isolated spinach (Spinacia oleraceda. L.) photosystem Ⅱ particles by the activity of oxygen evolution and chlorophyll fluorescence. When the particles were treated with Tris and urea, the oxygen evolution was inactivated and three polypeptides having molecular weights of 33 kDa, 24 kDa and 18 kDa were simultaneously released. But in NaCl-treated particles, two polypeptides of 24 kDa and 18 kDa were removed from PS Ⅱ particles. The oxygen evolution activities of Tris and urea-treated particles were not restored by adding cation ions (Mg^2+, Mn^2+ and Ca^2+), but the NaCl-treated particles were restored by exogenously added Ca^2+. The removal of these extrinsic polypeptides, especially 33 kDa, markedly showed the decrease of the variable fluorescence (Fv). These results are likely to be due to dissipate thermal energy by antenna of photosystem Ⅱ complexes.
