Mengzi's biological analogies of man's moral tendency need to be analyzed in order to understand his ethical perspective because he uses lots of analogies to advocate his own moral naturalism. The biological analogies he uses are composed of human body, plant's seeds and sprouts. First, Mengzi thinks that human beings have inborn moral nature as if our bodies are given and plants can be grown from their seeds. His ethical approach to define morality in terms of natural properties such as the Four Sprouts(四端) causes a philosophical debate with Gaozi who thinks that morality cannot be described by natural property. Second, we have a moral preference as if we have a physical desire. This kind of moral sentimentalism emphasizing the preference is continued to Jeong Yakyong's ethical theory that nature is a preference(性嗜好說). Third, if we examine our preference and desire, then we can find that the moral preference is more valuable than the physical desire. Fourth, the biological analogies accepts monism that mind and body are composed of material force(氣). For this reason, the innate moral tendency is manifested on body such as a facial expression, a visceral reaction, and affect. Finally, Mengzi's theory of Four Sprouts causes two different interpretation. One is Zhuxi's interpretation that Duan端 is the visible end(緖) of a thread out of pack, the other is Jeong Yakyong's interpretation that Duan端 is a starting point(始) to cultivate virtues. While Zhuxi considers the Four Sprouts as a clue to find virtues in one's mind, Jeong Yakyong believes that we can cultivate our virtues by preserving the Four Sprouts.

Whether to reduce the current 'screen quota' for domestic films in conjunction with the FTA discussions between Korea and the United States is one of the hotly debated issues in Korea. Using Toulmin's Argumentation Model, this study attempts to trace the use of data and warrants for each pro and con claims as portrayed in newspaper editorial columns and to find its rhetorical significance. A total of 67 editorial columns were collected from 9 nationwide news dailies in Korea for the purpose. The rhetorical analysis of those articles showed that the major warrants used in each pro and con opinion were absent of the potential issues of the opponents, which inherently fails to invite rebuttals from the opposite sides. This conceptual wall in each argumentation models implies an inactive conversation and subsequent absence of clash between the pro and con argumentation fields. It is thus suggested for opinion writers to find more adequate evidences to support the data and warrants to hold persuasive power of their respective claims, ultimately to enhance the public discourse among citizens.

This study analyzed correlation among peer evaluation, self-evaluation, and instructor evaluation of argumentation writing conducted in the 'Biology logic and essay' class. To this end, 14 pre-service biology teachers wrote argumentation four times, and peer evaluation, self-evaluation, and instructor evaluation were conducted on these results. The peer evaluation for argumentation writing averaged 2.70 points, the self-evaluation average was 2.68 points, and the instructor evaluation average was 2.71. Looking at the average of each sub-evaluation area, scientific knowledge was the highest in peer evaluation, and the composition area was the highest in self-evaluation. In addition, the area of scientific knowledge was the highest in the instructor evaluation. As a result of examining the standard deviation, the standard deviation of self-evaluation was the largest. As a result of analyzing the correlation between evaluation types, there was a high correlation between peer evaluation and instructor evaluation, and there was a moderate correlation between self-evaluation and instructor evaluation. On the other hand, there was no significant correlation between peer evaluation and self-evaluation. As a result of analyzing the correlation by evaluation area, there was no significant correlation between peer evaluation and self-evaluation in all four areas of scientific knowledge, scientific argumentation, composition, and expression. On the other hand, in the analysis between peer evaluation and instructor evaluation, there was a significant correlation in the areas of scientific knowledge, scientific argumentation, and composition. In addition, there was a significant correlation between self-evaluation and instructor evaluation only in the area of expression. The results of this study show that peer evaluation is highly likely to be applied in the 'Subject logic and essay' class. It also suggests that it is necessary to subdivide evaluation criteria according to the type of evaluation in order to use peer evaluation and self-evaluation.

본 논문에서 필자는 수학에 대한 구조주의적 해석들은 수학의 객관성을 설명하는 문제인 비공허성의 문제를 해결하지 못하고 있음을 보이고자 한다. 제거적 구조주의가 비공허성의 문제를 해결하지 못한다는 것은 대부분의 수학철학자들 사이에서 공유되는 견해이며, ante rem 구조주의는, 케래넨의 논증을 수정한 필자의 강한 논증에 의하면, 수학적 대상들에 대한 적절한 동일성 설명을 결코 제공할 수 없기 때문에, 결국 비공허성의 문제를 해결하지 못한다. 또한, 양상 구조주의자인 헬만의 경우에는, 비공허성의 문제에 대한 양상 구조주의적 해결을 가능케 해주는 주장(산수와 관련하는 경우, "${\omega}$-순서열 체계가 논리적으로 가능하다")에 이르는 그의 증명이, 필자의 판단에 따르면, 논점 선취의 오류를 저지르고 있다.

최근 가장 영향력 있는 수학적 실재론과 관련된 논변은 버지스와 로젠의 딜레마이다. 일종의 반-유명론적 논증인 버지스-로젠 딜레마는 유명론자들이 취할 수 있는 제한된 선택지를 제시한 후 그 어느 선택지도 적절하지 못함을 주장하는 것이다. 논자 역시 버지스-로젠 딜레마가 성립한다면 유명론이 가망 없는 전략임에 동의한다. 그러나 논자는 그들의 논의가 유명론 대 실재론이라는 대립구도 대신, 유명론 대 수학 및 과학이라는 잘못된 대립구도를 전제하고 있음을 본 논문을 통해 밝히고자 한다. 간략히 말해, 논자는 버지스-로젠 딜레마는 수학자 및 과학자들의 주장이 글자 그대로 실재론을 함의함을 전제하는데, 이것은 실제 수학 및 과학 활동과 일치하지 않을뿐더러, 이를 입증하기 위해서는 철학적 가정이 개입해야 함을 밝히고, 그 과정에서 유명론의 가능성을 모색하고자 한다. 이러한 논자의 전략은 유명론 진영 안의 특정한 입장을 지지하는 것은 아니다. 버지스-로젠 딜레마는 특정한 유명론의 문제라기보다는 유명론 자체의 가능성과 관련된 것이기 때문이다.

이 논문은 매디가 왜 수학적 실재론을 포기하고 그녀 특유의 수학적 자연주의를 표방하게 되었는지를 탐구하려 한다. 이 문제에 관하여 널리 받아들여지고 있는 한 가설에 따르면, 매디의 입장 변화는 콰인-퍼트남 필수불가결성 논증을 비판하고 포기함으로써 야기되었다. 필자는 이 가설이 지닌 설득력을 인정하지만, 그것만으로는 실재론의 포기의 충분한 이유가 될 수 없다고 생각하며, 그 대신 과학과 수학의 유비 문제가 매디의 입장 변화를 이해하는 데 더 나은 조망을 제공한다는 점을 보여주고자 한다. 이를 위해서는 콰인과 괴델에 크게 빚졌던 실재론자 시절 매디의 사유가 얼마만큼 수학과 과학의 유비에 지배되었는지를 살펴보아야 하는 동시에, 왜 매디가 이 유비를 포기함으로써 실재론을 포기하게 되는지를 이해하여야 한다. 아울러 이 유비의 포기에 대한 다소의 비판적 검토를 통해 매디의 수학적 존재론의 지적 여정을 왜 필자가 존재론적 퇴보라 믿는지에 대한 몇 가지 이유가 시사될 것이다.

The circumcenter of a triangle is introduced in logic geometry part of 8th grade mathematics. To handle certain characteristics of a figure through mathematical proof may involve considerable difficulty, and many students have greater difficulties especially in learning textbook's methods of proving propositions about circumcenter of a triangle. This study compares the methods how the circumcenter of a triangle is explored among the Elements of Euclid, a classic of logic geometry, current textbooks of USA and those of Korea. As a result of it, this study tries to abstract some significant implications on teaching the circumcenter of a triangle.
