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?

It is desirable to have an accurate expression on the temperature dependence of surface(or interfacial) tension Σ, because most of the interfacial thermodynamic functions can be derived from it. There have been proposed several equations on the temperature dependence of the surface tension, Σ(T). Among them Eotvos equation and the one modified by Katayama, which is called Katayama equation, for improving accuracies of Eotvos equation close to critical points, have been most well-known. In this article Katayama equation is interpreted on the basis of the cell model to understand the nature of the equation. The cell model results in an expression very similar to Katayama equation. This implies that, although Eotvos and Katayama equations were obtained on the basis of experimental results, they have a sound theoretical background. The Katayama equation is also modified with the phase volume replaced with a critical scaling expression. The modified Katayama equation becomes a power-law equation with the exponent slightly different from the value obtained by critical-scaling theory. This implies that Katayama equation can be replaced by a critical-scaling equation which is proven to be accurate.

초 중고 과학 교육에서는 과학적 소양의 함양을 그 학습 목표로 하고 있으며 이를 위해서 학생들은 과학자들이 어떻게 과학적 지식을 정립해 가는지를 이해하는 과정이 필요하다고 주장하고 있다. 하지만 학교에서의 과학 탐구는 오로지 경험을 중시하는 실험 위주의 과학 탐구를 실행, 어떻게 자신들이 수집한 자료가 세운 이론에 합당한지를 밝히는 논증활동이 없다는 것이 문제점으로 지적되고 있다. 이 고찰 논문은 학교에서의 과학 탐구가 과학자들의 그것과 다르며, 실질적 과학 탐구의 실현을 위해서는 교사들이 탐구 자체의 정의, 목표 및 요소를 정확하게 이해하고, 과학적 논증기회를 부여하기 위한 적절한 교수 전략을 개발해야 함을 보여주고 있다.

In this paper we attempt to introduce a new teaching method for Spanish grammar education, based on the Movement theory of the Generative Grammar and we want to show that this new method can explain Spanish grammar phenomenon more easily and effectively than the existing school grammar. For this purpose, we start with some nominal phrases and simple sentences of the Korean and Spanish languages. We find out the basic difference of the two languages by comparing their nominal phrases and simple sentences from the point of view of Movement theory. The difference is that the Korean language does not have movement phenomenon but the Spanish language does. This difference is consistent in all of complex clauses with relative pronouns. We show that with this theory we can teach Spanish nominal phrases, simple clauses, exclamative clauses and relative clauses in a unitary and effective method of explication without a supposition ad hoc.

Colin Rowe's 'Transparency' is one of core ideas applied to 20th Modern Architecture. It implies not only an optical characteristic, the perfectly clear, but also a broader spacial order, a simultaneous perception of different spacial locations. The former connected with physical attribute itself, and the latter deeply with the metaphorical idea of time, 'Simultaneity', embodying a new spacial quality. However, If we analyze the meaning of "Simultaneity" implicated in "Transparency" with the perspective of Henry Bergson's "Duration", there would be only little possibility as a solution to the problem of embodying a new spacial quality in architecture. As such a question emerging, this paper attempts to point out the problem of Colin Rowe's idea, "Simultaneity", and suggest a new architectural design method to overcome its inconsistency by interpretation and application of Bergson's "Image and Rhythm".

Physical Surroundings have been identified by a number of researchers as a powerful tool that can manipulate people's mood and cognition. A number of marketing practitioners have accepted this notion, given that physical surroundings are increasingly used as atmospheric stimuli in various retail environment as well as in restaurant. Yet there have not been practical reviews on consumer responses in restaurant setting/environment. By means of a literature review, this study examines how physical surroundings in restaurant settings function on displaying dinning atmosphere. It includes the conceptual definition and classifications of physical surroundings, effect of physical surroundings on customers' internal responses and behaviors, and testable research propositions and directions for future researches. This study is expected to make a substantial contribution to the understanding of restaurant manager and dinning atmosphere displayer about function of physical surroundings in dinning context.
