1백40억년 전의 대폭발(빅뱅)로 우주가 탄생했다는 우주대폭발생성론은 1992년 인공위성 코비(우주배경방사 탐색기)가 보내온 데이터로 과학적인 뒷받침을 받기 시작했다. 그런데 우주가 대폭발로 시작되었다는 것을 1948년 박사학위논문에서 수학적으로 처음 제시한 사람은 랠프 알퍼(Ralph Alpher,79세)였다는 사실을 알고 있는 사람은 많지 않다. 대신 뒤늦게 빅뱅이론을 뒷받침하는 우주배경방사를 발견하여 1978년 노벨물리학상을 받은 펜지아스(Amo Penzios)와 윌슨(Robert Wilson)은 세계적인 명사로 널리 알려져 있으나.

Residential segregation is often considered to be one of the social problems that intensify urban inequality This study reviews three different frameworks about the causes of residential segregation and tests their validity in the real world. The review focuses on racial/ethnic residential segregation in U.S. cities since it has been blamed for persistent socio-economic gap among racial/ethnic groups. The three different segregation frameworks include 'spatial assimilation' that attributes segregation to low degree of assimilation and acculturation, 'place stratification' to discriminatory practices in the housing and mortgage markets such as steering, blockbusting, and redlining, and 'resurgent ethnicity' to racial/ethnic preference in residential choice, particularly in-group attraction. As an effort to test their validity, the paper examined residential pattern changes of the four major Asian nationality groups through 1990s and found that their residences got decentralized but re-cluster in some selected suburbs. This supports 'resurgent ethnicity' largely and 'spatial assimilation' only partly.

In the beginning of the 21st century, UNESCO (The United Nations Educational, Scientific and Cultural Organization) thinks the key to the battle is "morality," and thus proposes the norm of ethic, morals and values. Not only have countries all over the world responded to the proposal, but we in Taiwan are also involved in the campaign, hoping through the new movement, the deviant values are to be modified. "Doctrine of the mean" is the best essence in Confucianism when it comes to the idea of government ruling by a virtuous king, who possesses sincerity, a crucial element to inspire better character. Moral teachings nowadays emphasize the fact that a person should own ethic virtue and behave accordingly. Only via constant practice and training can people obtain sincerity and virtues in the learning process, in which Confucianists rely mostly on self-discipline while more tactics are applied to modern education.

At this point, in Confucianism's schools debated about analysis for early theory and latterly it of nature between human and animal in Nongam Kim Changhyob's Confucianism. Oh Heeshang argued early theory about Shanguzaezungyongmunmok, written by Kim Changhyob, and establishment of theory about Yokuonyudozaelonshabyonnokbyon, written by him. Kim Changhup, brother of Kim Changhyob, argued so early theory about Shanguzaezungyongmunmok. O Yubong, student of Kim Changhyob, argued establishment of theory about Sobyon and Zabzee, written by Kim Changhyob. While, Yim Songzu argued early theory and establishment of theory about Zabzee. As a result, presenting researchers argued the same as. That is, they interpret early theory about difference of nature between human and animal in Kim Changhyob. they interpret about the same of nature between human and animal in it. However, Kim Changhyob wrote difference of nature between human and animal in Shanguzaezungyongmunmok. While, he wrote difference it and the same it in Yokuonyudozaelonshabyonnokbyon. He thought the same li between human and animal. However, he thought difference hyongki them. Furthermore, He wrote difference it and the same it in Zabzee. Therefore, they had depended on Kim Changhyob. As a result, posterity scholars interpreted early theory and establishment of theory about his theory. they depended on his authority. However, he changed himself theory.

Through reinvestigations of early years of King Young-Joe provincial castles, Jeonju Eupsung, this study seeks to broaden the understanding of castle construction of the later period of Chosun Dynasty. Jeonju Eupsung was established by reform-minded king and his loyalist Cho, Hyun Myung. Their new conceptual framework for reconstruction of Jeonju Eupsung was affected by Yoo, Hyung Won, a realist scholar of 17th century. It is obvious that adopted new administrative systems of financing, building and maintaining of Jeonju Eupsung were based on the his theories of castle. This study demonstrates that Jeonju Eupsung built by Cho, Hyun Myung, during the early years of King Young-Joe were based on those new concepts and systems of the new age. The study shows that the designer of this castle had in mind efficient construction design and execution and effective defense of provincial towns located on flat ground. And, the study explains how those original designer sought higher productivity through greater localization of securing resources and more detailed and improved organization of construction responsibilities. In short, this study seeks to prove that the provincial castles of the early 18th century reflected the new thinking on practicality that was spreading throughout the society of Chosun Dynasty at the time.

Lightly overconsolidated clays are commonly anisotropic, and exibit substantial ranges of approximately linear behavior at stress levels which do not produce yielding. The theory of cross-anisotropic elasticity is adopted to predict the stress-strain behavior of such an anisotropic soil. Equivalent elastic parameters $A^*$ and $B^*$ which express the relationships of stress and strain in the theory have been proposed. It is shown that constitutive relationships derived from the theory represents well the mechanical response of anisotropic soil.

The structure such as underground external walls of buildings, conduit and box culvert supports the surcharge loads (point, strip and line loads) . The vertical and horizontal stresses in a soil mass depend on the backfill width and wall friction, etc. The investigations described in this paper is designed to identify the magnitude and the distributions of the lateral and vertical pressure which is occurred by the narrowly backfilled soil in an open cut by the surcharge loads. For these purposes, model tests were performed for various width of backfill in a model test box by considering the wall friction using carbon rods. The results of test were compared with the theories of Weissenbach and VS Army Code and also with the results of the numerical analysis using finite difference method which introduces Mohr-Coulomb failure hypothesis.

거짓말쟁이 역설에 대한 전통적인 설명은 다음 두 가지로 주어진다. 역설을 일으키는 거짓말쟁이 문장이 자기지시적이기 때문에 역설이 발생하므로 자기지시적 문장을 금함으로써 그 역설을 피할 수 있다는 것이 첫 번째이고, 둘째는 모든 문장을 참이나 거짓이라고 주장하는 진리값에 대한 배중률(principle of bivalence)에 집착하기 때문에 그 역설이 발생한다고 생각하고 제3의 진리값을 갖는 문장이 있음을 인정해야 한다는 것이다. 이러한 전통적인 설명과 달리 진리 개념을 비일관적인 개념으로 보고 진리 술어와 그 외의 술어의 용법상의 차이를 설명함으로써 거짓말쟁이 역설에 대한 새로운 설명을 시도하고자 하는 것이 굽타의 "진리 수정론"이다. 굽타의 진리 수정론에 따르면, 진리 술어 외의 술어들은 그 외연이 고정적으로 산출되고 그 과정은 적용 규칙(rule of application)에 의해서 설명되지만 진리 술어는 순환적 정의처럼 고정된 외연을 만들어내지 못하고 단지 가설적 외연만 만들어 낼 뿐이다. 이렇게 진리술어의 가정적 외연을 산출해내는 과정은 수정규칙(rule of revision)에 의해서 설명된다. 요컨대 진리 수정론은 순환적 개념도 의미를 가질 수 있음을 보여주는 의미론적 구조틀이 있다는 것과 진리개념이 바로 그러한 의미구조틀에 의해서 의미를 갖는 순환적 개념이라는 것이다. 그리고 굽타는 그러한 의미구조 틀을 일정한 규칙을 갖는 함수로 설명하려고 시도한다. 즉 진리개념을 일관적인 것으로 보고 거짓말쟁이 역설을 해결해야 할 병리적 현상으로 보는 진리의 일관성론과 달리 굽타의 진리 수정론은 진리술어 자체가 비일관적이기 때문에 거짓말쟁이 역설은 그 술어의 속성상 자연스러운 것이지 피해야 만할 병리적 현상이 아니라고 주장한다. 필자는 의미론적 역설에 대한 여러 가지 설명 중에서 진리 수정론이 가장 설득력 있는 것으로 인정하고 그에 대한 가능한 반론을 검토하고 그에 대한 답변을 시도했다. 또한 진리 수정론을 통해서 거짓말쟁이 역설을 설명하고 -해결하려는 것이 아니라- 나아가서 진리 개념에 대한 이해를 제공해보려고 시도했다.

This paper seeks to deal with the point that in order to perform meaningful communication, a conscious act of reflexion must be involved. In other words, performance of communication inevitably requires self-reflexion. It is known that rationality and dialogism function as necessary preconditions and as goals of communication. But these concepts are very ambiguous because the communicational paradox is not considered. The interaction model could be thought to solve the paradox problems, but such solution can ultimately be seen as a result of ignoring the point that personal reflexion is necessary or covering up the logical problem by depending on concepts such as 'legitimation' or 'ideal discourse situation.' Therefore this paper views that the theory of communication based on Luhmann's system theory and constructivism has a more meticulous logics, and considers that the concept of reflexion specifically supplements the interaction model also by examining Schmidt's concept of fiction and Grant's concept of porous communication.
