  • 기존의 기호주의 적 추론 시스템은 경직성 문제로 인하여 유연성을 결여하고 있다. 이는 기호주의 적 지식표현 체계가 지식의 유연한 의미구조를 충분히 반영하고 있지 못할 뿐 아니라 추론 방법도 논리를 바탕으로 하기 때문이다. 이러한 문제를 해결하기 위하여, 우리는 최근 인공 신경 망에 기반 한 유연한 지식표현과 추론을 위한 연결주의 적 의미 망(CSN)을 제안한 바 있다. CSN은 인간의 유사성과 연관성에 기반 하여 근사 추론과 상식추론을 수행할 수 있다. 그러나 CSN 모델에서는 상위개념간의 관계를 표현하는 데 있어서 단순한 전향 신경 망을 이용함으로써 상위개념간의 일반적이고 구조화된 관계를 표현하거나 변수의 표현 및 바인딩의 어려움과 같은 문제점이 있었다. CSN모델의 이런 문제점을 해결하기 위해 본 논문에서는 상위개념간의 일반적이고 구조화된 지식표현을 가능하게 하고 추론이 용이한 기호주의 표현 체계와 이 표현 체계 안에서 의미구조를 표현하고 학습할 수 있는 연결주의 학습 모델인 CSN을 결합한 기호-연결주의 통합 시스템 SymCSN(Symbolic CSN)을 제안하고, 실험을 통하여 제안한 시스템이 인간과 유사한 유연한 지식표현과 추론을 위한 모델임을 보인다.

  • We study to design educational Logo-based microworld environment equipped with 3D construction capability, 3D manipulation, and web-based communication. Extending the turtle metaphor of 2D Logo, we design simple and intuitive symbolic representation system that can create several turtle objects and operations. We also present various mathematization activities applying the turtle objects and suggest the way to make good use of them in mathematics education. In our microworld environment, the symbolic representations constructing the turtle objects can be used for web-based collaborative learning, communication, and assessments.

  • Compared with other philosophers and writers who were engaged in architecture Georges Bataille was extraordinary. Because he produced anti-architectural discourse. This paper studied the Bataille's thinking with relation to architecture that used as a fundamental and privileged metaphor. Philosophy regarded as the foundation of all academic discipline needed architecture in order to show its system was durable, synthetic and hierarchical. The will to build a solid system of reasoning made philosophy to call architecture to pretend that it is structurally stable. Metaphor and representation is inevitable in philosophy. Then architectural image that supported by discourse of philosophy became a representation of sociocultural system. According to Bataille architectural representation justified existing power and belief system. With architecture Identity always represented the true and good. This kind of architectonic thinking erased the Other that allowed metaphysics and symbolic Against architecture Bataille produced writings of violation and excess corresponding to labyrinth. Labyrinth in fact made a formal structure of architecture possible to be a metaphor of symbolic system. Bataille's anti-architectural thinking paradoxically shows the importance of Architecture and give a chance to rethink the ethical aspect of architecture instead of aesthetics.

  • The purpose of this study is to define the fundamentals of one symbolic concept, so calles vestment-sign, based on the logical relationship of sign system about the trichotomy by charles S. Peice's sign concept for the communication system of meaning in the non-linguistic image domain. To prove the argument of vestment-sign, I selected 3 type of vestment language by styliste, Elsa Schiaparel-li. The third image vestmental chosen here, titled“Larme-Illusion(1938)”,printed by Salvad-or Dali will produce one symbolic proposition as a logical result which is generated and developed through the interpretation of other images. First of all the text, which is manifested by Elsa Schiaparelli's first image vestmental, tit-led“Notation Musical(1937)”and is symbolized as one category in the representation of the form, is regarded symbolic and metaphorical from a standpoint that the title and the meaning is connected to the form. The second image vestment, titled“Ruches Noirs(1938)”represents externally splendid feminity man-ifested by the symbolic and metaphorical expression. And the purity of sensitivity aiming to humanity in the detail of the poetic feeling of naturalism makes us imagine the battle fild of furious sensitivity. Like as the result of the battle, the third image stimulated our eyesight with the“absence”of dressing function. The proposition of the text,《Death》which the third image delivers, constructs sign system to bring up a meaning with the disappearance of physical“signifier”. This establishment of the symbolic concept presents the etymological authority of symbol generation called“Design”.

  • The queue theory is based on the assumption that most system are normally assigned to stay under steady state. Therefore, the initial problem can be represented by a symbolic model but such a representation does not permit analysis of all the interesting alternatives. When the solution to the problem is thus restricted to a particular subclass of available alternatives, the symbolic model can be solved by mathematics to deduce which alternative is optimal. However, when be consider slightly more complicated alternatives, the analytic procedures become interactable. The purpose of this study is to show how a simulation model enable us to handle the more complicated system after examining the characteristics of the complications that negate more complicated system. Then construct a simulation model and compare the solution of simulation models with analytic methods.

  • An efficient diagnostic approach for real-time operation aiding expert system in chemical process plants is discussed. The approach is based on the hybrid of the simplified symptom tree(SST) and the fault consequence digraph(FCD), representation of propagation patterns of fault states. The SST generates fault hypothesis efficiently and the FCD resolve the real fault accurately. Frame based knowledge representation and object-oriented programming make diagnostic system general and efficient. Truth maintenance system enables robust pattern matching and provides enhanced explain facilities. A prototype expert system for supports operation of naphtha furnaces process, called OASYS, has been built and tested to demonstrate this methodology. Utilization of diversified process symbolic data, produced using dynamic normal standards, overcomes the problem of qualitative Boolean reasoning and enhance the applicability.

  • In this paper, we present a overview of content-based image retrieval (CBIR) systems: its results and its problems. We propose our CBIR system currently based on color and texture. From the CBIR systems. we discuss the way to add semantic values in image retrieval systems. There are 3 ways for adding them: concept definition, machine learning and man-machine interaction. Along with this we introduce our preliminary results and discuss them in the goal of reaching semantic retrieval. Different result representation schemes are presented. At last, we present our work to build a complete annotated image database and our image annotaion program.

  • Go-Sul-Sik(高設式) On-Dol(溫突) houses have a combination of high Ma-Ru and high On-Dol structure. This type of house had been developed in the process of combining Ma-Ru with On-Dol. Go-Sul-Sik On-Dol houses give a clue to unveil exchanging process of Korean On-Dol and Ma-Ru. Go-Sul-Sik On-Dol can be understood as an architectural type of introducing On-Dol into the upper classes' Ma-Ru afterwards. Apparently, Go-Sul-Sik On-Dol houses were not a two-story building. But they had a two-story structure because of On-Dol rooms, which implied a symbolic rank and On-Dol's practicality as well as its being high. Go-Sul-Sik On-Dol houses were peculiar architectural type which realized lives of the very individual authority and symbolic representation within the strict Confucian society. It seemed to be derived from an alternative of the upper classes' architectural culture integrating an ideal into reality.

  • This thesis examines the origin, the change and the symbolic meanings of class representation, and offers a comparative study on the differences of class representation in the history of Korean and western costume on the basis of class representation methods and types shown from ancient times to 18C. In both eastern and western costume, the differences in status are commonly represented in the width and length of costume, color, textile, ornamental design, wearing, decoration, etc. The costume of noble class was wide and long, while that of common class was narrow and short so that it could be convenient for them to move around. Especially, from 16C to 18C in the west the costume of noble class was expanded to the extent that it was inconvenient for them to move around not only by skirt swelling by using hoop, but also by pad, ruff, lace, etc. This appears to show that they are not working class. Wearing and decoration of noble class were much more colorful, complicated and varied, while those of common class were simple and plain. In the west, the wearing of chiton and toga in Greece and Rome was different depending on social status. More specific look at the differences in class representation shown in the eastern and western costume reveals that the higher the rank, the more the women in both Gothic and Chosun period covered the body, thereby representing rank. In 18C, the women in both Rococo and Chosun period commonly showed excessive decoration and lavishness on their hair, and in this period the width of skirt was also commonly expanded to the longest extent, with a slight difference put aside.

  • This paper describes a preliminary work on prosody modeling aspect of a text-to-speech system for Thai. Specifically, the model is designed to predict symbolic markers from text (i.e., prosodic phrase boundaries, accent, and intonation boundaries), and then using these markers to generate pitch, intensity, and durational patterns for the synthesis module of the system. In this paper, a novel method for annotating the prosodic structure of Thai sentences based on dependency representation of syntax is presented. The goal of the annotation process is to predict from text the rhythm of the input sentence when spoken according to its intended meaning. The encoding of the prosodic structure is established by minimizing speech disrhythmy while maintaining the congruency with syntax. That is, each word in the sentence is assigned a prosodic feature called strength dynamic which is based on the dependency representation of syntax. The strength dynamics assigned are then used to obtain rhythmic groupings in terms of a phonological unit called foot. Finally, the foot structure is used to predict the durational pattern of the input sentence. The aforementioned process has been tested on a set of ambiguous sentences, which represents various structural ambiguities involving five types of compounds in Thai.
