The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

The basic rules and principles for designing structures with composite materials are briefly and intensively presented. The proposed design steps are explained. For preliminary design, use of quasi-isotropic properties is proposed. The validity of this proposal will be reported by separate papers.

The paper concerns Fuzzy C-Means clustering based Radial Basis Function neural networks (FCM-RBFNN) and the optimization of the network is carried out by means of Particle Swarm Optimization(PSO). FCM-RBFNN is the extended architecture of Radial Basis Function Neural Network(RBFNN). In the proposed network, the membership functions of the premise part of fuzzy rules do not assume any explicit functional forms such as Gaussian, ellipsoidal, triangular, etc., so its resulting fitness values directly rely on the computation of the relevant distance between data points by means of FCM. Also, as the consequent part of fuzzy rules extracted by the FCM - RBFNN model, the order of four types of polynomials can be considered such as constant, linear, quadratic and modified quadratic. Weighted Least Square Estimator(WLSE) are used to estimates the coefficients of polynomial. Since the performance of FCM-RBFNN is affected by some parameters of FCM-RBFNN such as a specific subset of input variables, fuzzification coefficient of FCM, the number of rules and the order of polynomials of consequent part of fuzzy rule, we need the structural as well as parametric optimization of the network. In this study, the PSO is exploited to carry out the structural as well as parametric optimization of FCM-RBFNN. Moreover The proposed model is demonstrated with the use of numerical example and gas furnace data set.

본 연구는 게임을 구성하는 핵심적인 구성 요소인 규칙을 특성에 따라 단계별로 분류하고 각 규칙 단계의 성립 근거와 개념을 정의한다. 이러한 정의를 바탕으로 게임 규칙의 변화 과정을 분석하고 게임 규칙이 진화를 통해서 발전해 나간다는 점을 확인한다. 디지털 게임 규칙의 변화 구조는 환경에 따라 이루어지는 생물의 진화 경로와 같은 구조를 가진다. 이러한 새로운 관점에서 바라보는 이 연구를 통해서 게임 규칙의 진화와 생물의 진화 경로의 구조적 유사성을 살펴본다. 또한 디지털 게임 규칙이 진화하는 과정을 새로운 시각을 통해서 분석하고 개념화하고자 한다. 나아가 이 연구를 바탕으로 게임을 새로운 학문적 대상으로서 재발견하고자 한다.

본 연구에서는 도서관의 편목 실무에서 표목의 취급 실태를 조사하였다. 한국의 표준목록규칙인 KCR4는 기본표목을 채택하지 않았으며, 표목의 형식에 관한 규정이 없는 규칙이다. 그러나 도서관의 편목 실무에서는 여전히 기본표목을 채택하는 경우가 많아 도서관 간에 기본표목의 취급에 관한 통일성이 없고, 통일표목의 형식으로 표목을 작성하는 도서관의 경우에도 적용할 규칙이 없음으로써 그 형식의 일관성이 결여되었다. KCR4의 방침에 따라 기본표목을 채택하지 않는 방식으로 목록레코드를 통일할 수 있기 위해서는 KORMARC포맷의 구조적 개선이 필요하다. 표목 형식의 일관성 유지를 위해서는 목록규칙에 관한 국제적 표준의 변화 추이에 따라 KCR4의 개정 방침이 확정될 때까지 과도적으로 적용할 수 있는 표목형식에 관한 규정이 제정될 필요가 있다.

Since he was a leading figure in nineteenth century architecture, Viollet-le-Duc's architectural theory is crucial to the foundation of modern architecture. He has been called a Gothic Revivalist, a Structural Rationalist and a Positivist. The first title was perhaps due to his vigorous restoration of Gothic works such as $N\hat{o}tre$ Dame, but he did not adore the Gothic style just for itself. Rather, he hoped to deduce some principles from the style. So how did he manage this? In his book "Entretiens sur l'Architecture (Lectures on Architecture), published between 1864 and 1872, he mentions using Descartes' four rules for reaching architectural certainty in contrast with the chaotic situation during that modernising period. Furthermore Viollet-le-Duc's theory can be seen as a serious attempt to translates Descartes' philosophical rules into systems of architectural speculation. Descartes' four rules of doubt are anchored in mathematical propositions, and without mathematical distinctions, none of these rules are valid. In other word, mathematics for Viollet is the yardstick of judgement between distinctness and indistinctness. Many architectural problems arise from this view. In this paper, the validities of applying Descartes' method of doubt to architectural discourse will be discussed in order to address the question:-Did Viollet-le-Duc clearly grasp Cartesian method by which memory was erased from the world?

With the increasing demand for interoperability among existing learning resource systems in order to enable the sharing of learning resources, such resources need to be annotated with ontologies that use different metadata standards. These different ontologies must be reconciled through ontology mediation, so as to cope with information heterogeneity problems, such as semantic and structural conflicts. In this paper, we propose an ontology-mapping technique using Semantic Web Rule Language (SWRL) to generate semantic mapping rules that integrate learning resources from different systems and that cope with semantic and structural conflicts. Reasoning rules are defined to support a semantic search for heterogeneous learning resources, which are deduced by rule-based inference. Experimental results demonstrate that the proposed approach enables the integration of learning resources originating from multiple sources and helps users to search across heterogeneous learning resource systems.

Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management. Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling. Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed. Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

Structural dynamics usually applies modal transformation rules aimed at de-coupling and/or minimizing the equations of motion. Proper orthogonal decomposition provides mathematical and conceptual tools to define suitable transformed spaces where a multi-variate and/or multi-dimensional random process is represented as a linear combination of one-variate and one-dimensional uncorrelated processes. Double modal transformation is the joint application of modal analysis and proper orthogonal decomposition applied to the loading process. By adopting this method the structural response is expressed as a double series expansion in which structural and loading mode contributions are superimposed. The simultaneous use of the structural modal truncation, the loading modal truncation and the cross-modal orthogonality property leads to efficient solutions that take into account only a few structural and loading modes. In addition the physical mechanisms of the dynamic response are clarified and interpreted.
