        NAMDANG'S THEORY ON THE NATURES OF HUMANS AND NON-HUMAN LIVING BEINGS AND HIS DEVELOPMENT OF ZHU XI'S THEORIES

        XING,LIJU,LIN,XI 계명대학교 한국학연구원 2016 Acta Koreana Vol.19 No.2

        This article examines a thesis by Namdang, a Confucian scholar in Chosŏn Korea, on the natures of humans and non-human living beings, using Zhu Xi's li (理) - qi (氣) theory. Regarding the sameness or difference between li and qi, Zhu Xi formulated different opinions in his early and later life and was also at times inconsistent in his works of a certain period. To a certain extent, Zhu Xi's thoughts lacked coherence, which led to subsequent debates. In seeking to develop Zhu Xi's li-qi theory, Namdang put forward his original thesis of Trichotomous Nature, which significantly enriched Zhu Xi's ideas. The “nature transcending the appearance of things” (K. ch'ohyŏnggi 超形氣) refers to a pure xing (K. sŏng 性; nature), concerned with only li without considering the influence of qi from the perspective of a unitary source (K. irwŏn 一原; one source). At this stage, everything shares the same li and xing. The “nature originated from temperament” (K. in'gijil 因氣質) demonstrates the shared nature for the same species as well as the difference in nature across species, thus being an endowmentdependent li. At this stage, for the same species, they share the same li, qi, and xing, while for varying species, there is a difference in li, qi, and xing. The “nature mixed with temperament” (K. chapkijil 雜氣質) considers the xing of pure qizhi (K. kijil 氣質; physical temperament) in which all creatures differ. It is thus a concept that demonstrates the particularity in all things, with varying differences in li, qi, and xing.

        Particle size distributions and concentrations above radiators in indoor environments: Exploratory results from Xi`an, China

        Xi,Chen,Angui,Li 대한환경공학회 2015 Environmental Engineering Research Vol.20 No.3

        Particulate matter in indoor environments has caused public concerns in recent years. The objective of this research is to explore the influence of radiators on particle size distributions and concentrations. The particle size distributions as well as concentrations above radiators and in the adjacent indoor air are monitored in forty-two indoor environments in Xi'an, China. The temperatures, relative humidity and air velocities are also measured. The particle size distributions above radiators at ten locations are analyzed. The results show that the functional difference of indoor environments has little impact on the particle size distributions above radiators. Then the effects of the environmental parameters (particle concentrations in the adjacent indoor air, temperatures, relative humidities and air velocities) on particle concentrations above radiators are assessed by applying multiple linear regression analysis. Three multiple linear regression models are established to predict the concentrations of PM10, PM2.5 and PM1 above radiators.

        Enhancement of Mechanical and Antimicrobial Properties of Thermoplastic Poly(lactic acid)/Quaternized Chitosan-Saponite Nanocomposites

        Xi,Xi,Weijun,Zhen,Shengzhen,Bian,Wentao,Wang 한국고분자학회 2015 폴리머 Vol.39 No.4

        Water-soluble N-(2-hydroxyl) propyl-3-trimethyl ammonium chitosan chloride (HTCC) was prepared with 2, 3-epoxypropyl trimethyl ammonium chloride grafting to the amino groups of chitosan. Then, chitosan quaternary ammonium intercalated saponite (HTCC-saponite) was synthesized with HTCC and saponite by ultrasonication intercalation. Compared with chitosan, HTCC had a good antibacterial effect. Thermoplastic poly(lactic acid) (PLA)/HTCC-saponite nanocomposites were prepared with HTCC-saponite and PLA by melt intercalation. Fourier transform infrared (FTIR) and nuclear magnetic resonance (1H NMR) showed that HTCC was successfully synthesized by a modified method of two-step reaction. Moreover, X-ray diffraction (XRD) and scanning electron microscope (SEM) also showed that saponite was intercalated or nearly exfoliated by HTCC. It was shown the mechanical properties of PLA/HTCC-saponite nanocomposites attained the optimum when the content of HTCC-saponite was 1 phr. The studies of thermal stability, crystallization and rheological behavior of PLA/HTCC-saponite nanocomposites demonstrated that PLA/HTCC-saponite nanocomposites exhibited high performance compared with PLA.

        일반논문 : 조산본적적선학사상론석(曹山本寂的禪學思想論析)

        습세평 ( Xi Ping Xi ) 한국불교선리연구원 2011 禪文化硏究 Vol.10 No.-

        조산본적(曹山本寂)은 조동종(曹洞宗) 선학사상을 집대성한 사람이며, 그의 선학사상은 완전하면서도 심오하다. 중국불학계에서 본적의 선학사상에 대하여 전반적으로 체계적인 연구성과는 많지 않으며, 또한 그 연구성과 간의 차이점이 적지 않다. 본고에서는 본적의 선학사상에 대하여 주로 "응물현형(應物顯形)"과 "현본원진(幻本元眞)"의 불성론, "편정회호(偏正回互)"를 핵심으로 하는 군신오위설(君臣五位說), "삼종타(三種墮)"와 "사이류(四異類)"로 하는 선수론(禪修論)을 포함하여 전체적으로 살펴서 정리해보기로 하였다. 그리고 본 논문에서 본적의 선학사상은 고도로 이론적이며 사변적이고, 선학을 철학적으로 이론화하는 경향을 구현해냈으며, 또 유가(儒家)를 융합하는 종교의 정치윤리적 색채를 드러냈음을 밝혔다. Benji succeeded and innovated the Zen thoughts of Caodong sect, His Zen thought is complete and profound, In the Chinese Buddha research world the comprehensive research results about the Benji`s Zen thought is not to be many, moreover the difference actually many. This article attempts on the Benji`s Zen thought to do one combs comprehensively, mainly including Foxingtheory, Five King - liegeman Seats theory and the gymnosophist theory of Three Duo and Four Dissimilations. It is thus clear that the Benji`s Zen thought has the extremely high theory speculation, manifests the imperial sacrifices study wise physics and chemistry tendency, also passes appears welcomes presents Confucianism religious politics ethics color.

        Assessment of the Severity of Coronavirus Disease: Quantitative Computed Tomography Parameters versus Semiquantitative Visual Score

        Yin,Xi,Min,Xiangde,Nan,Yan,Feng,Zhaoyan,Li,Basen,Cai,Wei,Xi,Xiaoqing,Wang,Liang 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.8

        Objective: To compare the accuracies of quantitative computed tomography (CT) parameters and semiquantitative visual score in evaluating clinical classification of severity of coronavirus disease (COVID-19). Materials and Methods: We retrospectively enrolled 187 patients with COVID-19 treated at Tongji Hospital of Tongji Medical College from February 15, 2020, to February 29, 2020. Demographic data, imaging characteristics, and clinical data were collected, and based on the clinical classification of severity, patients were divided into groups 1 (mild) and 2 (severe/ critical). A semiquantitative visual score was used to estimate the lesion extent. A three-dimensional slicer was used to precisely quantify the volume and CT value of the lung and lesions. Correlation coefficients of the quantitative CT parameters, semiquantitative visual score, and clinical classification were calculated using Spearman's correlation. A receiver operating characteristic curve was used to compare the accuracies of quantitative and semi-quantitative methods. Results: There were 59 patients in group 1 and 128 patients in group 2. The mean age and sex distribution of the two groups were not significantly different. The lesions were primarily located in the subpleural area. Compared to group 1, group 2 had larger values for all volume-dependent parameters (p < 0.001). The percentage of lesions had the strongest correlation with disease severity with a correlation coefficient of 0.495. In comparison, the correlation coefficient of semiquantitative score was 0.349. To classify the severity of COVID-19, area under the curve of the percentage of lesions was the highest (0.807; 95% confidence interval, 0.744–0.861: p < 0.001) and that of the quantitative CT parameters was significantly higher than that of the semiquantitative visual score (p = 0.001). Conclusion: The classification accuracy of quantitative CT parameters was significantly superior to that of semiquantitative visual score in terms of evaluating the severity of COVID-19.

        The Therapeutic Effects of Tectorigenin on Chemically Induced Liver Fibrosis in Rats and an Associated Metabonomic Investigation

        Xing-Xi,Gao,Jun-Hua,Wu,Da-Hua,Shi,Yun-Xi,Chen,Jiang-Tao,Cui,Yu-Rong,Wang,Chun-Ping,Jiang 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.8

        The aim of this study was to investigate the effects of tectorigenin on chemically induced liver fibrosis in rats. Liver fibrosis was induced in rats with carbon tetrachloride, a diet high in fat, cholesterol and alcohol in the drinking water. Our results indicate that tectorigenin treatment significantly inhibited the increases in the activities of alanine aminotransferase (ALT),aspartate aminotransferase (AST) and the increases in the serum levels of hyaluronate (HA), laminin (LN) and procollagen III N-terminal peptide (PIIIP); tectorigenin treatment also significantly inhibited the increases in the amount of collagen in the livers of the fibrogenic rats. Chemically induced liver fibrosis caused a drop in the serum albumin concentration and a decrease in the ratio of albumin to globulin (A/G). Tectorigenin caused a remarkable increase at a dose of 30 mg/kg, but only a slight increase at the lower doses. Tectorigenin was also able to inhibit the increase in the liver lipid peroxidation (LPO), as well as the decrease in the activities of liver superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), caused by liver fibrosis. In addition, we present a related metabolic profile determined, using a 1H NMR spectroscopy and multivariate pattern recognition techniques. The results were consistent with the pathological examination, liver function analysis and liver fibrosis marker analysis. Furthermore, tectorigenin does not cause acute toxicity.

      • 中国政治学理论范式的现象学维度: 政治学理论视野中的身体与政治

        林曦 ( Lin¸ Xi ) 성균관대학교 성균중국연구소 2021 중국사회과학논총 Vol.3 No.1

        现象学作为欧陆哲学强调个体经验、意图和生活世界的理论研究进路, 也进入了中国的政治学学科的视野, 这两者相互结合, 形成了“政治现象学”这一新兴的学科领域。本文就旨在讨论, 政治现象学作为一个理论范式, 可以首先以身体为切入点, 来探讨我们规训身体的过程中所存在的性别规范、性别政治的问题, 因为身体是在政治科学研究之中被悬置起来的一个“前科学假设”。身体首先作为个体的身体, 但作为一个种群的人类的身体总和, 就不再是仅仅属于每一个活生生的个体所有, 而是变成了政治的主体、国家的权力对象, 政治发展和管控的目标, 制度安排的客体, 从而进入了政治学研究的视野。故此, 政治现象学可以从身体出发, 来揭示这一现象背后所被隐藏的政治诉求和制度安排, 并从新的学术视角理解和解释一个互联互通的世界中中国特殊条件下公共政策形成过程、社会资源配置和国家与社会关系的互动关系的历史变迁和政治现实。 As a theoretical paradigm, phenomenology may be seemingly distant from political science, which focus on the research of the political in human society. The wedding of phenomenology, an experience-oriented approach of philosophical inquiries, with the study of the political may avail for us a new theoretical lens to examine human activities. This so-called “political phenomenology” may start from “human body” as its entry point, to discuss the gendered norms and politics in the disciplining of human body. This human body is not merely in singular terms; on the contrary, there may be double or multiple bodies that intersect and form a shared community, namely the world of our daily life. Moreover, there is a tertiary level which points to the multiplication of bodies or body in its multitude. The dimension of “global imaginary” shall be duly added to our discussions, bringing near those distant “others” and enabling their presence to motivate those sentiments of the ethics of responsibility. The introduction of phenomenology into political science, as a new theoretical paradigm, can be rendered politically productive by tapping into the pools of both phenomenological inquiries and politico-scientific research.

        Effect of Template Removal on Synthesis of Organic-Inorganic Hybrid Mesoporous MCM-48

        Ya,Nan,Zhao,,San,Xi,Li,Chong,Soo,Han,San,Xi,Li 대한화학회 2012 Bulletin of the Korean Chemical Society Vol.33 No.10

        Post-synthesis is used to synthesize organic hybrid inorganic mesoporous sieves. In this method, the activity and structure of the base sieve are crucial to obtain the definable hybrid materials. The chemical and physical properties of the base can be largely changed either by the final step of its synthesizing processes, by template removal which is accomplished with the oxidative thermal decomposition (burning) method or by solvent extraction method. In this paper we compared two methods for the post-synthesis of organic hybrid MCM-48. When the template was extracted with HCl/alcohol mixture, the final product showed larger pore size, larger pore volume and better crystallinity compared to the case of the thermal decomposition. The reactivity of the surface silanol group of template free MCM-48 was also checked with an alkylsilylation reagent CH2=CHSi(OC2H5)3. Raman and 29Si NMR spectra of MCM-48 in the test reaction indicated that more of the organic group was grafted to the surface of the sample after the template was removed with the solvent extraction method. Direct synthesis of vinyl-MCM-48 was also investigated and its characteristics were compared with the case of post-synthesis. From the results, it was suggested that the structure and chemical reactivity can be maintained in the solvent extraction method and that organic grafting after the solvent extraction can be a good candidate to synthesize a definable hybrid porous material.
