Secularization and Desecularization of Modern Korean Buddhism

Cho, Ki-Ryong 한국선학회 2021 한국선학 Vol.- No.58

본고는 현대 한국불교의 세속화 현상과 탈세속화 방안을 연구한다. 세속화와 탈세속화는 승려의 가치관과 승가의 운영, 그리고 종단의 제도 측면에서 분석이 이루어진다. 승려의 가치관은 승려가 현상과 대상에 대해 어떠한 가치를 부여하느냐를 다룬다. 승가의 운영은 승가의 정치화와 영리화를 다룬다. 종단의 제도는 종헌과 종법을 분석대상으로 하였다. 조사분석 결과, 승려 가치관의 범부화(凡夫化), 승가 운영의 정치화와 영리화, 종단 제도의 세속사회법 모방이라는 문제점들을 발견할 수 있었다. 이에 대한 본고의 각 분야별 탈세속화 방안은 다음과 같다. 승려 가치관의 탈세속화를 위해서는 승려가 견성(見性)과 오도(悟道)에 이를 수 있도록 승가의 교육, 승려의 일상 생활환경, 스승의 지도가 유기적으로 연계되어야 한다. 승가 운영의 탈세속화를 위해서는 승려가 수행과 전법에 전념할 수 있도록 신도가 교단 운영의 주체로서 자리 잡을 수 있어야 한다. 종단 제도의 탈세속화를 위해서는 다수결에 의하여 소수의 의견이 일방적으로 배제되지 않도록 종헌·종법을 율장의 화합 정신이 반영될 수 있게 제·개정하여야 한다. This study aims to diagnose the secularization of modern Korean Buddhism in terms of the Buddhist monks’ values, the management of the community of saṃgha, and the legal system of the Buddhist order, and to suggest methods for desecularization in each area. In modern society, the Buddhist monks’ values are becoming materialistic like those of secular people. The management of the saṃgha is becoming politicized and commercialized like a secular organization, and the legal system of the Buddhist order imitates social legislation. This study suggests the following methods for desecularization: in the Buddhist monks’ values, the education of the saṃgha, a daily living environment for Buddhist monks, and the guidance of the preceptors have to be unified in order to see people’s true natures and awaken people to the way. Moreover, in the management of the community of saṃgha, lay Buddhists must take their place as the main agents of managing the system of the Buddhist community so that Buddhist monks can devote themselves to Buddhist practice and missionary work. In the legal system of the Buddhist order, it is necessary to abolish the secular democratic system of elections and adopt a Buddhist democratic system known as karman(kalma 羯磨).

2R,3R-butanediol, a bacterial volatile produced by Pseudomonas chlororaphis O6, is involved in induction of systemic tolerance to drought in Arabidopsis thaliana.

Cho, Song Mi,Kang, Beom Ryong,Han, Song Hee,Anderson, Anne J,Park, Ju-Young,Lee, Yong-Hwan,Cho, Baik Ho,Yang, Kwang-Yeol,Ryu, Choong-Min,Kim, Young Cheol APS Press 2008 Molecular plant-microbe interactions Vol.21 No.8

<P>Root colonization of plants with certain rhizobacteria, such as Pseudomonas chlororaphis O6, induces tolerance to biotic and abiotic stresses. Tolerance to drought was correlated with reduced water loss in P. chlororaphis O6-colonized plants and with stomatal closure, indicated by size of stomatal aperture and percentage of closed stomata. Stomatal closure and drought resistance were mediated by production of 2R,3R-butanediol, a volatile metabolite of P. chlororaphis O6. Root colonization with bacteria deficient in 2R,3R-butanediol production showed no induction of drought tolerance. Studies with Arabidopsis mutant lines indicated that induced drought tolerance required the salicylic acid (SA)-, ethylene-, and jasmonic acid-signaling pathways. Both induced drought tolerance and stomatal closure were dependent on Aba-1 and OST-1 kinase. Increases in free SA after drought stress of P. chlororaphis O6-colonized plants and after 2R,3R-butanediol treatment suggested a primary role for SA signaling in induced drought tolerance. We conclude that the bacterial volatile 2R,3R-butanediol was a major determinant in inducing resistance to drought in Arabidopsis through an SA-dependent mechanism.</P>

본 논문에서는 강한 직접파 성분과 반사파 성분이 존재하는 2채널 환경에 라이시안 페이딩이 결합된 형태의 이동통신 모델을 제시하였으며 신호의 성능 및 전파 지연 영향을 분석하였다. 이때 직접파 성분을 제1경로, 반사파 성분은 제2경로로 모델링하였으며 라이시안 페이딩 파라메타, 전파 지연, 상대 전력을 파라메타로 하여 신호의 잔파지연 양향 및 시스템의 성능을 평가하였다. 연구 결과, 단일경로보다 2경로 모델의 경우가 신호의 성능이 심하게 열화되며 2경로 라이시안 모델은 전파 환경을 해석하는데 매우 유용한 모델임을 확인할 수 있었다. 또한 2경로 채널 모델에서 전파 지연은 상대 전력의 영향보다 오율 성능에 큰 변화를 미치는 요인이 됨을 확인 할 수 있었다.

Miscibility and Properties of Ethyl-Branched Polyethylene/Ethylene-Propylene Rubber Blends(Ⅱ)

Cho, Ur Ryong 한국고무학회 2002 엘라스토머 및 콤포지트 Vol.37 No.2

2몰% 에틸가지를 포함하는 에틸 가지화 폴리에틸렌[PE(2)]과 에틸렌-프로필렌 몰비가 50:50 으로 같지만 입체규칙성이 다른 랜덤-에틸렌-프로필렌 고무(r-EPR), 교호-에틸렌-프로필렌고무(alt-EPR) 및 이소탁틱-교호-에틸렌-프로필렌 고무(iso-alt-EPR)를 에틸렌-프로필렌 고무의 입체규칙성의 차이에 대한 혼화성과 물성의 차이를 조사하기 위하여 혼합하였다. 혼합된 블렌드의 결정화도는 고무상 EPR 성분의 증가에 따라 감소되었으며, EPR의 입체규칙성이 작을수록, 혼합조성의 증가할수록 감소하였다. 열역학적 interaction parameter( x) 값은 3가지 블렌드 모두 거의 영에 가까운 값을 나타내어 본 블렌드계는 PE(2)의 녹는점 가까이 또는 그 이상에서 상호간 섞일 것으로 판단되었다. 녹는점(Tm)과 결정화온도(Tc)의 측정에서부터 세가지 블렌드는 혼합조성과 입체규칙성에 관계없이 직선관계를 보여주어 이 블렌드계의 PE(2)의 용융거동은 주로 희석효과(diluent effect)에 기인함을 알 수 있었다. Small angle light scattering(SALS) 방법에 의한 PE(2)의 spherulite의 크기는 세가지 블렌드계가 EPR의 혼합비 증가에 따라 증가하였으며, 같은 혼합비에서는 r-EPR>alt-EPR>iso-alt-EPR> 순서로 증가하였다. Ethyl-branched polyethylene [PE(2)] containing 2mole% ethyl branch and three ethylene-propylene rubbers (EPR's) having the same ethylene(E)-propylene(P) molar ratio(E/P=50/50) with different stereoregularity, that is, random EPR (r-EPR), alternating-EPR (alt-EPR) and isotactic-alternating-EPR (iso-alt-EPR) were mixed for the investigation of their properties depending on the stereoregularity. Crystallinity of the prepared blends decreased with increasing content of amorphous EPR because of a decrease in both the degree of annealing and kinetics of diffusion of the crystallizable polymer content. With blend composition, crystallinity was reduced with the stereoregularity in EPR. The thermodynamic interaction parameter( x) for the three blend systems approximately equals to zero near the melting point. These systems were determined to be miscible on a molecular scale near or above the crystalline melting point of the crystalline PE(2). From the measurement of Tm vs. Tc, the behavior of PE(2) is mainly due to a diluent effect of EPR component. The spherulite size measured by small angle light scattering (SALS) technique depended upon blend composition, and stereoregularity of EPR. The size of spherulite was enlarged with the content of rubbery EPR and the decrease of stereoregularity in EPR.

Miscibility and Properties of cis-Polybutadiene/Ethyl-Branched Polyethylene Blends (II)

Cho, Ur-Ryong The Polymer Society of Korea 2000 Korea polymer journal Vol.8 No.2

Cis-Polybutadiene (cis-PBD) and the three polyethylenes (PE's) having different branch content were mixed to investigate crystallinity, thermodynamic interaction parameter(c), and diluents effect. Crys-tallinty of PE's decreased with increasing content of amorphous cis-PBD because of a decrease in both the degree of annealing and kinetics of diffusion of the crystallizable polymer content. The thermodynamic interaction parameter(c) for the three blend systems approximately equals to zero near the melting point. These systems were determined to be miscible on a molecular scale near or above the crystalline melting point of the crystalline PE's. From the measurement of T$\sub$m/ vs. T$\sub$c/ behavior, all the three blends showed a straight line for a plot of T$\sub$m/ vs. T$\sub$c/. This result means that the melting behavior of PE is mainly due to a diluent effect of cis-PBD component.

Role of the rice hexokinases OsHXK5 and OsHXK6 as glucose sensors.

Cho, Jung-Il,Ryoo, Nayeon,Eom, Joon-Seob,Lee, Dae-Woo,Kim, Hyun-Bi,Jeong, Seok-Won,Lee, Youn-Hyung,Kwon, Yong-Kook,Cho, Man-Ho,Bhoo, Seong Hee,Hahn, Tae-Ryong,Park, Youn-Il,Hwang, Ildoo,Sheen, Jen,Jeo American Society of Plant Physiologists 2009 Plant Physiology Vol.149 No.2

<P>The Arabidopsis (Arabidopsis thaliana) hexokinase 1 (AtHXK1) is recognized as an important glucose (Glc) sensor. However, the function of hexokinases as Glc sensors has not been clearly demonstrated in other plant species, including rice (Oryza sativa). To investigate the functions of rice hexokinase isoforms, we characterized OsHXK5 and OsHXK6, which are evolutionarily related to AtHXK1. Transient expression analyses using GFP fusion constructs revealed that OsHXK5 and OsHXK6 are associated with mitochondria. Interestingly, the OsHXK5DeltamTP-GFP and OsHXK6DeltamTP-GFP fusion proteins, which lack N-terminal mitochondrial targeting peptides, were present mainly in the nucleus with a small amount of the proteins seen in the cytosol. In addition, the OsHXK5NLS-GFP and OsHXK6NLS-GFP fusion proteins harboring nuclear localization signals were targeted predominantly in the nucleus, suggesting that these OsHXKs retain a dual-targeting ability to mitochondria and nuclei. In transient expression assays using promoterluciferase fusion constructs, these two OsHXKs and their catalytically inactive alleles dramatically enhanced the Glc-dependent repression of the maize (Zea mays) Rubisco small subunit (RbcS) and rice alpha-amylase genes in mesophyll protoplasts of maize and rice. Notably, the expression of OsHXK5, OsHXK6, or their mutant alleles complemented the Arabidopsis glucose insensitive2-1 mutant, thereby resulting in wild-type characteristics in seedling development, Glc-dependent gene expression, and plant growth. Furthermore, transgenic rice plants overexpressing OsHXK5 or OsHXK6 exhibited hypersensitive plant growth retardation and enhanced repression of the photosynthetic gene RbcS in response to Glc treatment. These results provide evidence that rice OsHXK5 and OsHXK6 can function as Glc sensors.</P>

Improvement of Plant Protein Solubilization and 2-DE Gel Resolution through Optimization of the Concentration of Tris in the Solubilization Buffer

Cho, Jin-Hwan,Cho, Man-Ho,Hwang, Hee-Youn,Bhoo, Seong-Hee,Hahn, Tae-Ryong Korean Society for Molecular and Cellular Biology 2010 Molecules and cells Vol.29 No.6

It is important to solubilize acetone-precipitated proteins before isoelectric focusing (IEF) to achieve high resolution 2-DE gels. To resolve the maximum possible number of plant protein spots, we developed an improved solubilization buffer for plant proteins. We demonstrated that the resolution of 2-DE gels increased dramatically as the concentration of Tris-base increased, with maximum solubilization obtained at 200 mM Tris-base (Ly200T). The Ly200T buffer was more effective than the commonly used solubilization buffer containing 40 mM Tris at solubilizing acetone-precipitated plant proteins. Use of the Ly200T buffer to solubilize proteins resulted in an increase in intensity of approximately 30% of plant protein spots in the larger-than-40 kDa region of the gel. The Ly200T buffer also improved the resolution of abundant and basic proteins. Thus, the Ly200T buffer can be used to achieve greater resolution of protein spots in plant proteomics research.
