『중용(中庸)』에서 성(誠)과 지(智)의 관계와 공부론적 의미

한상인 ( Han Sang-in ) 한국교육사학회 2018 한국교육사학 Vol.40 No.2

본 연구에서는 『중용』에서의 성(誠)과 지(智)의 관계를 해명하였다. 곧 성과 지, 양자 사이에 필연적 연관성이 있는가의 문제인데, 결론은 다음과 같다. 첫째, 성(誠)은 천지자연과 성인(聖人)의 측면에서 지(智)와 필연적 연관성이 있다. 성(誠)은 천지자연과 성인(聖人)의 자기 전개의 근본원리로, 천지자연과 성인 자신을 이루고[成己] 동시에 타존재를 이루어낸다[成物]. 이때 성기·성물은 각각 인(仁)·지(智)의 덕에 말미암는다. 따라서 천지자연과 성인에게서 성(誠)은 지(智)와 필연적으로 관계한다. 둘째, 군자(君子)는 지(知) 공부를 통하여 지(智)를 함양하고 성(誠)에 이르기 위해 노력하는 존재다. 군자는 그 존재적 한계로 말미암아 온전히 성(誠)할 수 없다. 다만 성하기 위해 노력할 뿐이다 [誠之]. 성하기 위한 노력은 지행(知行)의 공부로 구체화하는데, 지 공부는 성인이 타존재를 이루어내기 위해서 제정한 예의(禮儀)·위의(威儀)에 대한 공부이다. 군자는 성인이 제정한 예의·위의를 통하여 성인의 역사적 안목을 학습한다. 이상의 성과 지의 관계 해명을 통하여 다음의 공부론적 의미를 도출하였다. 첫째, 주자학 내 사학(史學)의 위상이 경학(經學)에 비해 결코 낮지 않음을 확인했다. 둘째, 격물치지(格物致知)의 지공부가 성(誠)에 다다르기 위한 필수적 과정임을 확인했다. This article clarifies the relationship between sincerity(誠) and wisdom(智) in the 『Zhongyong』, addressing the problem of whether or not sincerity guarantees wisdom. Regarding this question, two points are concluded. First, from the standpoint of sages(聖人) and the cosmos(天地自然), sincerity does guarantee wisdom. As the basic principle of their self-unfolding, sincerity is how the cosmos and sages simultaneously actualize themselves(成己) and other beings(成物). Here the actualizations of selves and others arise through the virtues of ren(仁) and wisdom respectively. Therefore, to sages and the cosmos, sincerity guarantees wisdom. Second, junzi(君子) is a being who strives to become sincere by cultivating wisdom through intellectual(知) study. In accord with his existential limitations, he can never be wholly sincere. He can only strive to be sincere[誠之]. This endeavor to become sincere is made concrete through intellectual and practical(知行) kung fu. The intellectual portion of this kung fu pertains to the civil and dignified manners (禮儀, 威儀) that the sages had established for the sake of actualizing other beings. It is through these manners that a junzi studies the historical perspectives of the sages. The following inferences concerning kung fu are made based on this clarification of the relationship between sincerity and wisdom. First, it is confirmed that in Neo-Confucianism the subject of history(史學) was not at all lower than that of classics(經 學). Second, it is confirmed that the intellectual kung fu of gewuzhizhi(格物致知) is a necessary process for attaining sincerity.

This study investigates the effectiveness of proposed modal analysis method using the pseudo-force to deal with supplemental damping in the seismic analysis of elastic systems. On this study, the one-way asymmetric systems are considered because these will undergo lateral and torsional motion simultaneously due to supplemental damping and stiffness eccentricities. For the purpose of this study, the analysis is performed with the consideration of large range of system parameters, such as asymmetric of system and distribution of supplemental damping. And, the CPU running times are compared to investigate the effect of additional procedure on proposed methods. Finally, these proposed methods are applied to a three-story one-way asymmetric building with supplemental damping on each floor. These analytical results are compared with those obtained by direct integration method and conventional approximate method, which neglects the off-diagonal terms of the transformed damping matrix. It is found that the proposed methods can significantly improve the accuracy of the analytical results compared to conventional approximate method on large range of system parameters although it need a little additional analysis time.

The Meshfree method is a method used to establish a system of algebraic equations for the whole problem domain without using predefined mesh for the domain discretization. Point interpolation method is based on combination of radial and polynomial basis functions. Introducing of radial basis functions overcomes possible singularity problem. Furthermore, the interpolation function is applicable for all points scattered over in influence domain and thus shape functions are of delta function property, which makes the implementation of essential boundary conditions much easier than the meshfree methods based on the moving least-squares approximation. In this study, an adaptive node generation procedure in the radial point interpolation method is proposed. Since we set the initial configuration of nodes by subdivision of background cell, abrupt changes of inter-nodal distance between higher and lower error regions are unavoidable. This unpreferable nodal spacing induces additional errors. To obtain the smoothy nodal configuration, it's regenerated by local Delaunay triangulation algorithm. This technique was originally developed to generate a set of well-shaped triangles and tetrahedra. In order to evaluate the error estimation technique, cantilever type plate was investigated. To demonstrate the performance of proposed scheme, the results of making optimal nodal configuration with adaptive refinement method are investigated for stress concentration problems.

In shape-finding process of membrane structure by dynamic relaxation method, three-node triangular membrane elements, the finite elements, are generally used. But serious changes of curvature in many membrane structures can make the mesh distortion. As a result, the final form of the membrane is not appropriate for the patterning and the stress analysis. To solve these problems, the viscous damping element is introduced to control the mesh distortion. It is placed at three sides of a triangular membrane element and the nodal force, residual force, can be controled by the damping force. Also, it does not prevent the convergence of residual force. The damping element is applied to various models to evaluate the improvement of mesh distortion and it is verified that the introduction of viscous damping element can control the mesh distortion, efficiently.

The purpose of this study is to investigate the churning behavior of customers in mobile telecommunication market. As the mobile telecommunication market becomes mature, the importance of the switching behavior of current customers is more and more recognized. This research is to develop the churning model of current customers as a two-stage choice model where a customers first decides whether to switch or not and in the second stage s/he chooses which carrier to switch to. When current customers face the decision of whether to switch from the current service provider, there are two factors which makes the customers to switch from the current service provider. One of the factors is the brand value related to brand preference, the other is inertia tendency related to customer`s demographic characteristics and consumption/usage characteristics.

In this study, a method for large deformation elastic-plastic analysis of space frame is presented. The method is based on large deformation formulation, which was developed initially for elastic systems, and is extended herein to include elasto-plastic effect. The method is based on an Eulerian formulation, which takes into consideration the effects of large joint translations and rotations. Local member force-deformation relationships are based on the beam-column approach, and the change in member chord lengths caused by axial strain and flexural bowing are taken into account. The effect of axial force of member on bending and torsional stiffness, and on plastic moment capacity, is included in the analysis. The material is assumed to be ideally elasto-plastic, and yielding is considered to be concentrated at member ends in the form of plastic hinges. The arc length approach is applied to trace the post-buckling range of elastic and elasto-plastic problems. Four numerical examples are presented which indicate that the method of analysis is highly accurate in predicting large deformation, buckling and post-buckling of elasto-plastic response of structures.
