For any thought and knowledge, its growth and development has close relation with the society where it is developed and grow. As Feuerbach says, the birth of spirit needs an existence of two human beings, i. e. the social background, as well as the birth of body does. But, at the educational viewpoint, the spread and the growth of such a thought or knowledge that influence favorably the development of a society must be also considered. We would discuss the goal and the function of mathematics education in relation with the prosperity of a technological civilization. But, the goal and the function are not unrelated with the spiritual culture which is basis of the technological civilization. Most societies of today can be called open democratic societies or societies which are at least standing such. The concept of rationality in such societies is a methodological principle which completes the democratic society. At the same time, it is asserted as an educational value concept which explains comprehensively the standpoint and the attitude of one who is educated in such a society. Especially, we can considered the cultivation of a mathematical thinking or a logical thinking in the goal of mathematics education as a concept which is included in such an educational value concept. The use of the concept of rationality depends on various viewpoints and criterions. We can analyze the concept of rationality at two aspects, one is the aspect of human behavior and the other is that of human belief or knowledge. Generally speaking, the rationality in human behavior means a problem solving power or a reasoning power as an instrument, i. e. the human economical cast of mind. But, the conceptual condition like this cannot include value concept. On the other hand, the rationality in human knowledge is related with the problem of rationality in human belief. For any statement which represents a certain sort of knowledge, its universal validity cannot be assured. The statements of value judgment which represent the philosophical knowledge cannot but relate to the argument on the rationality in human belief, because their finality do not easily turn out to be true or false. The positive statements in science also relate to the argument on the rationality in human belief, because there are no necessary relations between the proposition which states the all-pervasive rule and the proposition which is induced from the results of observation. Especially, the logical statement in logic or mathematics resolves itself into a question of the rationality in human belief after all, because all the logical proposition have their logical propriety in a certain deductive system which must start from some axioms, and the selection and construction of an axiomatic system cannot but depend on the belief of a man himself. Thus, we can conclude that a question of the rationality in knowledge or belief is a question of the rationality both in the content of belief or knowledge and in the process where one holds his own belief. And the rationality of both the content and the process is namely an deal form of a human ability and attitude in one's rational behavior. Considering the advancement of mathematical knowledge, we can say that mathematics is a good example which reflects such a human rationality, i. e. the human ability and attitude. By this property of mathematics itself, mathematics is deeply rooted as a good. subject which as needed in moulding the ability and attitude of a rational person who contributes to the development of the open democratic society he belongs to. But, it is needed to analyze the practicing and pursuing the rationality especially in mathematics education. Mathematics teacher must aim the rationality of process where the mathematical belief is maintained. In fact, there is no problem in the rationality of content as long the mathematics teacher does not draw mathematical conclusions without bases. But, in the mathematical activities he presents in his class, mathematics teacher must be able to show hem together with what even his own belief on the efficiency and propriety of mathematical activites can be altered and advanced by a new thinking or new experiences.

Previous studies show that working wives in the market contribute to the family economy that affects the family member's behaviors as consumers. Accordingly, the consumer behavior among working wives would be differ form that among nonworking wives. As the number of working wives in the market is increasing, this study focuses on the estimation of the degree of rationality in purchasing decision making among wives in relation to their working status. Therefore, this study attempts to construct an rationality index of a purchasing decision making both at a high and a low involvement situation by working and nonworking wives, and analyzes the differences in the results of the two groups. This study also examines how the rationality indices vary with the selected socioeconomic variables. The data are obtained from self-administered questionnaires from a sample of 217 working and 191 nonworking wives at Seoul and Seongnam in 1986. The statistical methods used in this study are Factor Analysis, Multiple Regression, and Analysis of Variances. The major findings of this study are as follows; 1) The mean value of the rationality index among nonworking wives is higher than that among working wives. Under a high involvement situation, the mean value of the rationality index among working wives is negative. Therefore, it is likely that nonworking wives make purchasing decisions more rationally than working wives. 2) The higher the degree of wive's education, the more rational the purchasing decision making. Under a low involvement situation, the higher the monthly family income, the more rational the purchasing decision making . under the same situation, the shorter the duration of marriage , the more rational the purchasing decision making. 3) Under a low involvement situation, the rationality indices of working wives vary with their occupations. The rationality indices among those in selling and service jobs are lower than those among those in professional jobs. 4) The impact of the selected socio-economic variables on the degree of the rationality in purchasing decision making differs depending on whether the wife is working or not. Under a low involvement situation, the positive impact of the monthly family income on the rationality in purchasing decision making is stronger among nonworking wives than among working wives. Under the same situation, the negative impact of the duration of marriage on the rationality is stronger among nonworking wives than among working wives.

합리적이라는 것을 이성적 원리와의 부합이라고 이해할 때, 우리는 두 종류의 합리성을 구분할 수 있다. 한 가지는 기왕에 정해진 목표를 가장 효율적으로 달성하는데 적용되는 원리와 관련된 합리성으로 이를 도구적 합리성이라고 부를 수 있을 것이다. 이 경우 목표는 우리의 욕망에 의해 정해진다고 생각된다. 다른 하나는 목적자체를 결정하는 일과 관련된 목적 지향적 합리성이라고 부를 수 있다. 전통적으로 합리주의자들은 이 후자의 합리성만을 인정해 왔다. 그러나 현대 과학 문명은 도구적 합리성을 바탕으로 하고 있는데, 이러한 태도가 현대 과학 문명의 위기적 상황과 밀접한 관련이 있다고 생각된다. 합리주의자들은 인식적 합리성이 목적 지향적 합리성의 전제가 된다고 생각했는데, 그러나 과학 지식과 관련된 인식적 합리성, 즉 과학적 합리성은 20세기 후반 상대주의자들의 도전으로 중대한 위기를 맞고 있다. 이 글에서는 이러한 상황에서 도구적 합리성 이외에 목적 지향적 합리성을 인정할 수 있는 길이 있는지 그 가능성을 탐구하고 있다.

그 동안 경영판단의 합리성은 자기 이익 극대화라는 경제적 합리성에 국한되어 판단되었다. 그러나 환경, 사회, 기업의 이익을 조화와 균형의 관점으로 추구하는 ESG 시대의 경영합리성은 새로운 판단 기준을 요구하고 있다. ESG 경영의 목표는 지속가능발전이다. 지속가능발전은 과거 경제의 목표였던 부의 축적을 넘어 전체 사회와 함께 발전하는 상생과 공정한 발전 등 전체 사회의 행복을 지향한다. 지속가능발전이 도모하는 전체 사회의 행복은 아리스토텔레스의 관점에서 공동체 구성원인 시민의 최고선과 다르지 않다. 이에 본 연구에서 필자는 ESG 시대의 경영자에게 요구되는 새로운 경영합리성을 아리스토텔레스의 시민 개념과 ESG 경영의 주체인 '기업시민' 개념을 비교함으로써 모색하고자 시도하였다. 이러한 비교·분석을 통해 ESG 시대의 새로운 경영합리성은 재무적 이익과 환경적·사회적 이익의 조화와 균형에 있고, 이것은 기업의 최고의사결정권자의 올바른 신념과 실천적 지혜에 달려 있음을 주장한다. 이러한 주장은 국내 대표기업의 지속가능경영보고서와 관련 연구에서 객관적인 성과로 확인할 수 있었다.

While the Internet has been used to galvanise people for the collective good, many have voiced concerns over the noise and vitriol present online and polarisation. In Singapore where the government regulates traditional mainstream media such as print and broadcast, the online space has been described as a "Wild Wild West" rife with rumours, untruths and misinformation. Such developments do not only exert a potential negative effect on the deliberative nature of public discourse but also skew bias towards the online space, affecting the ability of online users to communicate with authority and power. This study seeks to examine the rationality of the cyberspace through using a new "rationality" framework to analyse political discourse online. Comprising objectivity, emotionality and partisanship, the rationality framework was applied to a content analysis of 197 blogs with political content in 2014. The analysis indicated that the online political space was not the Wild Wild West that it was touted to be with significant levels of objectivity and non-partisanship. There was a stark absence of emotional discourse, and relationships were observed between bloggers' anonymity and rationality. Cognisant of academia's and policymakers' interest on the quality and effects of online discourse, the proposed analytical framework and the study findings hold implications for both developed and developing countries.

인식적 합리성은 전적으로 진리 연관성의 문제라는 것이 인식론의 정설이다. 이 글은 이런 정설을 비판하여, 주제의 인식적 가치가 탐구 및 믿음의 인식적 합리성에 영향을 미친다고 주장한다. 구체적으로, 이 글은 한 탐구가 알 가치가 없는 주제와 관련될 때 인식적으로 불합리하다고 주장하며, 그 탐구의 결과로 나타나는 믿음도 인식적으로 불합리하다고 주장한다.
