인간은 선과 악을 함께 가지고 있기 때문에 양면적이라 할 수 있다. 이러한 인간은 악을 더욱 구체화하기 위해 악을 형상화하여 조형적 요소로 악의 상징물을 만들었다. 이에 본 연구자는 악의 개념부터 인간이 가지고 있는 악에 본질이 상징물로 표현되었을 때 나타나는 조형성에 관하여 조사 분석해 보고자 하였다. 조형성의 분류 항목을 구축하여 설문지를 작성하여 다음과 같은 분석의 결과를 도출하였다. 구성유형에서는 문자보다는 그림 또는 기호로 표현되었으며, 표현대상에서는 신화 속 인물과 동물의 형태로 나타났다. 레이아웃에서는 방사형이 가장 많이 나타났으며 묘사방법에서는 단순성과 복잡성의 형태로 외곽형태는 원형이 가장 높게 나타났다. 이러한 구성유형의 항목들이 높은 점수를 보인 상징물은 서로간의 조형적인 상관관계로 그려지고 사용되었으며, 발전해 왔다는 것을 알 수 있었다.

A general framework for the nonlinear geometric analysis of elastic space trusses is presented. Both total Lagrangian and finite incremental formulations are derived from the three key ingredients of statics, kinematics and constitutive law. Particular features of the general methodology include the preservation of static-kinematic duality through the concept of fictitious forces and deformations, and an exact description for arbitrarily large displacements, albeit small strain, that can be specialized to any order of geometrical nonlinearity. As for the numerical algorithm, we consider specifically the finite incremental case and suggest the use of a conventional, simple and flexible arc-length based method. Numerical examples are presented to illustrate and validate the accuracy of the approach.

In this paper we will discuss a type of inductive learning called learning from examples, whose task is to induce general description of concepts from specific instances of these concepts. In many real life situations, however, new instances can be added to the set of instances. It is first proposed within the framework of rough set theory, for such cases, an algorithm to find minimal set of rules for decision tables without recalculation for overcall set of instances. The method of learning presented here is base don a rough set concept proposed by Pawlak[2][11]. It is shown an algorithm to find minimal set of rules using reduct change theorems giving criteria for minimum recalculation with an illustrative example. Finally, the proposed learning algorithm is applied to fuzzy system to learn sampled I/O data.

Vibration isolators and anti-vibration mounts are ideal, for example, in creating floating floors for gymnasiums, or performance spaces. However, it is well-known that there are great difficulties on isolating vibration transmission in structural steel components, especially steel floors. Besides, the selection of inertia blocks, which are usually used by engineers as an effective vibration control measure, is usually based on crude methods or the experience of the engineers. Thus, no simple method or indices have been available for assessing the effect of inertia blocks on vibration isolation or stability of vibratory systems. Thus, the aims of this research are to provide further background description using a FE model and present and implement a modal approach, that was validated experimentally, the latter assisting in providing improved understanding of the vibration transmission phenomenon in steel buildings excited by a velocity-source type of excitation. A better visualization of the mean-square velocity distribution in the frequency domain is presented using the concept of modal expansion. Finally, the variation of the mean-square velocity with frequency, whilst varying mass and/or stiffness of the coupled system, is presented.

We propose a formation-keeping and changing methods for outdoor multiple mobile robots in chained form. Our proposed method is designed to maintain the follower to its desired distance and orientation with respect to the pole using the concept of virtual force such as potential field. The client robots use a behavior-based control to perform kinematic control to keep formation under the centralized system in our software framework. The relationship of each poles that is expressed by set of distance and angle is the description of the formation type and the type converting is performed using this set. In addition, we also examine the stability and capability in the simulation and experiments with real robots.

Stand-alone global position system receiver based on C/A code tracking generates position error of 100m mainly due to the selective availability and ionospheric and tropospheric delay errors. The differential GPS is the most commonly used method for removing those bias range error components. The relative GPS, although somewhat restrictive in its use, is ideally suited to the car monitoring system for improved Automatic Vehicle location, especially where the DGPS infrastructure is not available. The RGPS does not require any additional hardware, facility or external infrastructure and can be operated within the system with existing host computer and communication link. This paper presents detailed description of the RGPS concept and its implementation for real-time data processing. Performance of RGPS is evaluated with real data and is compared with DGPS.

This study aims to examine the brief statement about the historiography of architecture by the French philosopher Michel Foucault and the possibility of a historical description according to his method. His historiographic proposition, "the history of architecture back in (the) general history of techne," is a novel idea not only for his contemporaries but also for us. To grasp the meaning of Foucault's proposition, we begin by considering his position with regard to architecture or architectural space in certain discussions till then. We then compare his standpoint on historical recognition with other viewpoints about historical narratives that can be found in books written since 1930. Finally, we interpret the concept of "techne" in the sense of "relation," whose objectivation is for him his concern on architecture and examine possible aspects and their limits.

본 연구는 출처주의 발전과정, 범주, 그 의미를 살펴보고 오늘날 기록관리환경에서 새롭게 변화된 출처주의의 경향을 검토, 기록물 관리에 있어 이것의 적용을 위해 고려될 수 있는 실질적 방안을 모색한 것이다. 단일 출처, 물리적 기록물체를 강조하던 기존의 출처주의는 행정조직의 변화와 유동성, 네트워크 발달 등에 따라 점차 개념적 추상적 기능적 출처개념으로 변화하고 있다. 새로운 출처주의의 적용을 위한 방안으로 먼저 기록물 자체에 대한 기술과 생산자 그리고 그 생산내력에 대한 기술을 분리, 각 영역을 링크시켜 통제하는 방안이 모색될 수 있다. 이 경우 기능별 생산연원의 추적은 물론, 기록물에 대한 다양한 출처의 규명도 가능해진다. 또 분류와 스케줄을 통합, 생산단계, 혹은 그 이전 단계로부터 출처를 통제하기도 하며, 전자기록물의 경우 메타데이터의 구축을 통해 출처와 내력관계를 관리하기도 한다. 그러나 무엇보다 중요한 것은 국제적 기준에 부합하는 국가적 기술규칙의 마련을 통해 출처정보의 구조화와 통제를 할 수 있어야 하며, 출처 및 폰드 구성을 위한 가이드라인을 마련, 그 일관성 유지에도 주의를 기울여야 한다.

The main objective of this paper is to develop an improved model for the analysis of liquefaction potential and to predict excess pore pressure (EPP) using the proposed model that can simulate behavior of saturated sand under earthquake loading conditions. The damage concept is adopted for the development of the proposed model. For the development of the model, a general formulation based on experimental results and damage potential using cumulative absolute velocity (CAV) is proposed for a more realistic description of dynamic responses of saturated sand. Undrained dynamic triaxial tests are conducted using earthquake loading conditions. Based on test results, the NCER-NCW function in terms of $w_d$ and CAV is developed. Procedure for the evaluation of EPP and determination of model parameters for the proposed model is presented as well. For the determination of initial liquefaction, the minimum curvature method using the NCS-NCW curve is proposed. It is observed that predicted initial liquefaction using the proposed method agrees well with measured initial liquefaction. From results of additional undrained dynamic triaxial tests, it is seen that predicted EPP generation using the proposed model agrees well with measured results for earthquake loading cases.

Summarizing the differences in Chinese-Vietnamese bilingual news plays an important supporting role in the comparative analysis of news views between China and Vietnam. Aiming at cross-language problems in the analysis of the differences between Chinese and Vietnamese bilingual news, we propose a new method of summarizing the differences based on an undirected graph model. The method extracts elements to represent the sentences, and builds a bridge between different languages based on Wikipedia's multilingual concept description page. Firstly, we calculate the similarity between Chinese and Vietnamese news sentences, and filter the bilingual sentences accordingly. Then we use the filtered sentences as nodes and the similarity grade as the weight of the edge to construct an undirected graph model. Finally, combining the random walk algorithm, the weight of the node is calculated according to the weight of the edge, and sentences with highest weight can be extracted as the difference summary. The experiment results show that our proposed approach achieved the highest score of 0.1837 on the annotated test set, which outperforms the state-of-the-art summarization models.
