이 논문에서는 문제해결의 입장에 서서 수학사에서 중요한 의미를 지닌 데카르트의 <기하학>을 고찰한다. 문제해결의 일반적 원리를 천명한 것만이 아니라 실제로 당면한 문제를 해결하기 위하여 새로운 방법을 찾아내는 것이야말로 데카르트가 문제해결에 관하여 후세에 영향을 크게 남긴 업적이라 할 수 있다. 따라서 본고에서는 그의 방법에 초점을 맞추어 분석하도록 한다.

A purpose of this study is to study on Rene Descartes's mind-body theory in medical aspect. Though Rene Descartes was not so much a doctor as a philosopher, he had health and medical science at heart. When he came into the world in 1596, he was in poor health. Therefore, he suffered from his bad health. Descartes's ideas absolutely colored Western thought for three hundred years, especially, his mind-body theory, mechanistic life-view, and reductionism had important effect on medical study and science of public health. As a rule, we know that his mind-body theory was applicable to mind-body dualism, and his mind-body dualism was connected with biomedical model of medicine. But by this study, his mind-body theory was not only mind-body dualism but also mind-body monoism. And he asserted mind-body interaction too. In other words, he advocated mind-body dualism in scientific aspect, but he knew mind-body monoism from his experence. He confessed this fact to Princess Elizabeth of Bohemia, he wrote mind-body interaction in $\boxDr$Discours de la methode$\boxUl$, $\boxDr$Meditationes de prima philosophia$\boxUl$, and $\boxDr$Traite des passions de 1'ame$\boxUl$ etc. However, only mind-body dualism of his mind-body theories was written in our medical text book, morever mental realm was excluded from the persuit of learning Descartes advocated a mechanistic world-view and mechanistic life-view, he regarded human body as a machine part. And a paticent corresponds to a troubled machine, a doctor deserves a repairman. But this point of view made holistic understanding of man impossible. Descartes divide the whole into basic building blocks, we named the approach Reductionism. Reductionism led to ontological concept in medical science, bacteriology established 'specific cause-specific disease-specific therapy'. We examined medical influence of Descartes's thought, we need to draw out a philosophic basis of medical science and science of public health by a close study of his records.

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?

We give an elementary proof of Descartes' theorem for polyhedra. Since Descartes' theorem is equivalent to Euler's theorem for polyhedra, this also gives an elementary proof of Euler's theorem.

본 논문은 중등 수학영재를 위한 심화학습 주제로서 데카르트 정리의 도입가능성을 고찰하였다. 데카르트 정리는 오일러 정리와 논리적으로 동치관계가 성립할뿐 아니라, 미분기하의 중요개념인 가우스-보네 정리와도 위계적으로 연결되고 있어 수학적 측면에서 그 가치가 높다. 수학교육적 측면에서도 데카르트 정리는 '다각형의 외각의 합은 $360^\circ$ 이다'라는 평면기하적 성질을 유추적 사고과정을 통해 입체기하적 성질로 일반화하여 지도될 수 있는 주제이다. 이 논문에서는 데카르트 정리의 도입을 위한 방법으로서 엄밀한 증명방법이 아닌 유추적 사고를 통해 재발명할 수 있는 대안적인 방법을 소개하였다.

It can be said that postmodernism shows a tendency to be anti-Descartes in the sense that it criticizes modern rationality which has started from Descartes. This paper suggests the relationship between modernism and postmodernism and that between. traditional Mathematics and fuzzy logic in three aspects, and shows that fuzzy logic tends to be a postmodern science in Mathematics.

수학에서 분석(analysis)의 역사는 고대 그리스에서부터 시작되었다. 그리스의 기하적 분석법은 16세기 비에트$(Vi{\`{e}}te)$와 데카르트(Descartes) 이후 방정식을 이용한 문제해결(대수적 분석법)로 확장되었으며, 그 결과 대수는 분석을 위한 기술(art for analysis)로 대변되었다. 그리고 뉴헌(Newton)과 라이프니츠(Leibniz)에 의해 미적 분학이 탄생되면서 분석은 대수에서 한 걸음 더 나아가 오늘날 수학의 한 분야인 해석학으로 발전되었다. 그 동안 수학교육학 연구에서는 분석과 관련된 논의가 파푸스(Pappus)와 데카르트를 중심으로 다루어져 왔으나, 지금까지 라이프니츠의 역할과 그에 대한 연구는 거의 다루어지지 않았다. 본 연구는 라이프니츠의 철학 및 논리학을 바탕으로 그 가운데 분석과 관련된 그의 아이디어를 살펴보고, 이를 통해 그가 생각한 수학에서의 분석의 역할에 대해 논의하였다.

The goal of this research is to find a theoretical base of the ecological paradigm, and explore the architectural ramification of the paradigm. To understand the paradigm in a historical and philosophical context, the paradigm is comparatively analyzed with the contrasting, Descartes-Newtonian paradigm to reveal the influence of each respective paradigm in various fields of science, such as logic, physics, bio-medical sciences, psychology, social sciences, and architecture. The affect in architectural ream is studied to find out the patterns of how the two contrasting paradigms have been materialized since the era of modern architecture and later. At the end, this paper proposes the possible architectural application methods of ecological design process.

Anterior neck burns represent a major reconstructive challenge due to severe sequalae including restriction in movement and poor aesthetic outcomes. Common treatment options include skin grafting with/without dermal matrices, and loco-regional and distant free flap transfers with/without prior tissue expansion. Such variation in technique is largely influenced by the extent of burn injury requiring resurfacing. In order to optimize like-for-like reconstruction of the anterior neck, use of wide, thin and long flaps such as the anterolateral thigh (ALT) perforator flap have been reported with promising results. Of note, some patients have a tendency towards severe scar contractures, which may be contributed by the greater extent of inflammation during wound healing. We report our experience at 4 years' followup after secondary reconstruction of severe, anterior neck burn contractures in two patients by harvesting the ALT flap with a butterfly design. This technique provides adequate wound resurfacing of the burned neck and surrounding areas, and provides good neck extensibility by addressing both anterior and lateral aspects of the scar defect simultaneously. Such a flap design reduces tension on wound edges and thus, the risk of contracture recurrence in what remains a particularly challenging type of burn reconstruction.
