One of the characteristics of modem mathematics is to use algebra in every fields of mathematics. But we don't have the exact definition of algebra, and we can't clearly define algebraic thinking. In order to solve this problem, this paper investigate the history of algebra. First, we describe some of the features of proportional Babylonian thinking by analysing some problems. In chapter 4, we consider Greek's analytical method and proportional theory. And in chapter 5, we deal with Diophantus' algebraic method by giving an overview of Arithmetica. Finally we investigate Viete's thinking of algebra through his ‘the analytical art’. By investigating these history of algebra, we reach the following conclusions. 1. The origin of algebra comes from problem solving(various equations). 2. The origin of algebraic thinking is the proportional thinking and the analytical thinking. 3. The thing that plays an important role in transition from arithmetical thinking to algebraic thinking is Babylonian ‘the false value’ idea and Diophantus’ ‘arithmos’ concept.

This Paper aims to elaborate on the origin of thinking mind. And this is a cooperative project between philosophy and neuroscience and brain science. I have written this paper in admiration for the achievements of twentieth century neuroscience and brain science, and out of desire to assist the subject in future. Much of the history of modern philosophy, from Descartes and Kant forward, consists of failed models of brain. As Edward O. Wilson precisely said, the shortcoming is not the fault of the philosophers, who have doggedly pushed their methods to the limit, but a straightforward consequence of the biological evolution of the brain. Guiding that investigation down pathways that will illuminate brain research is a task of neuroscience and brain science. Investigating logical relations among concepts is a philosophical task. If we are to understand the neural structures and dynamics that make perception, thought, intentional behaviour possible, clarity about these concepts and categories and their relations is essential. Hence our joint venture of philosophy and science. Sure, it is human beings that perceives, not parts of its brain. And it is human beings that who think and reason, not their brain. But the brain and its activities make it possible for human beings-not for it-to perceive and think, to feel emotions, and to form and pursue projects. Thus We try to investigate and reveal the origin of thinking mind as follow: 1) The difference between chimpanzee and human beings 2) brain and mind 3) the origin of thinking 4) the wisdom of nature.

In this paper, we deal with the algebraic thinking from the perspective of ‘process’ and ‘object’ aspects. Generally, mathematical concepts have come from the concrete process. We consider the origin of algebra as the arithmetic calculations. Also, the concept of school arithmetic is beginning from actions or procedures. However, in order to develop the alge- braic thinking and to apply this thinking, we have to see the history of algebraic thinking, and find this duality. Next we investigate various researches relating to the ‘process-object duality’. Theses studies suppose that the concept formation and thinking process should be stared from the process-object duality. Finally, we reinterprete many difficulties in algebra - equals sign, variables, algebraic expressions, and linear equations, the principle of permanence of form- from the perspective of the process-object duality.

As a applied art, Architecture is a synthetic art for dwelling and settlement. It has started with the origin of the human. and Artistical-technological indicator, include not only materiality but also immateriality such as history and society. After 20C, various categories of thinking is a undergoing rapid change. especially, beginning in 1900, The intrinsic value of "Fine Art" had lost their competitive power in the face of industrial revolution's mass production. and it has been displaced by a "new concept", such as a conveyance of meaning or rational way of thinking. This change means free from the tradition and custom of a past. for that reasons, Due to the nature of applied art, it always include design symbolism and designer's thinking is mainly processed in their own system of thinking. Symbolism for the art was distinguished from a general concept by the connotative meaning that called "the dual image". Therefore, at the start, this study will define about design and symbolism with a architecture as a applied art. then, Analysis the expression tendency of the contemporary architecture and modification. as a result, It aim to systematize mapping process and suggest the classification of various visual cue.

The year of 2009 marks the $200^{th}$ anniversary of Charles Darwin's birth and the 150th anniversary of the publication of his book, On the Origin of Species. Having survived the 150 years of hardening and tempering, Darwin's theory of natural selection is now more comprehensive and powerful than ever. It casts its shadow over nearly all academic disciplines and societal sectors. It truly revolutionized the way we look at the world and ourselves. In the midst of Darwinian revolution, however, Korea remains as a backward country as far as the understanding of Darwin and his theory is concerned. A variety of intellectual activities organized to celebrate the Year of Darwin is helping to narrow the gap. This article summarizes the kinds of such activities held in Korea this year and explains how Darwin made all this possible. To paraphrase the famous quotation by Theodosius Dobzhansky, I now dare to say, "Nothing in life makes sense except in the light of evolution".

This study considered stools not just as a tool for sitting but with their symbolicity as well. Regarding the changes and meanings of general stools and X-stools, this paper studied their images and explanations as well as literatures by quoting as it limited their range from the ancient times till Neo-classicism. In conclusion, the origin of stools exists in consciousness and also the social hierarchy of authority. There still remain the elements of X in any way along with the functions. This proves that furniture has reason for existence even today not just for its functions but something beyond that. Along with the historic flow of X-stools, we should know that there is diversity of thinking in the area of stools. In understanding furniture design or furniture, now is the time to approach to it in various ways, and it is expected that new design can be born through that thinking.

The objective of this study examines that a country-of-origin and a congruity between country-of-origin of brand and country-of-origin of production effect on consumers' product preference respectively. To test this hypothesis, we used stimulus material including product photos with brand and its production description. Nation selected for study is defined as developed country, Korea, underdeveloped country, and tape record, sports shoes, and cosmetic, tissue is selected, they have characteristics with thinking vs feeling, level of involvement, private vs public. The result of analysis show that the effects of country-of-origin on product preference is different over country. The product of developed country is preferred by subjective, and following Korea, underdeveloped country. This result imply that country-of-origin effect on consumers' product preference and product evaluation positively. And we found that the degree of congruity between country-of-origin of brand and country-of-origin of production has very substantial impact on product quality judgement and product preference above and beyond brand and country-of-origin of production main effects. This study contributes to a understanding of effects of country-of-origin at the perspective of congruity, and extend level of generalization of country-of-origin effect by testing various product characteristic and congruity.

The objectives of this study are to consider about the research of a costume and a discussion about a system of costume by practical science scholar in the late period of Chosun Dynasty. The result are descrived as follows: 1. The purpose that practical sciellce scholars researched a costulne was not only the intellectual research but also to make a basis in order to reform a uncorrected costume's system. Their study had two point. The one was the investigating research about the origin and change of the costume. The other was the study about a formation of costume. 2. The practical science scholars determined the directions to reform a wrong costumes' system on the basis of the research about a costume. They had three directions. Those were a conservatism, a rationalism to think the realities of life and a reformation. 3. The practical science scholars' thinking was to pursue the origin form and the practical use. This two axis show the direction to improve our costulne's culture now a day.

The origin of "Fire" in Traditional Chinese Medicine is summed up based on observation and knowledge of natural fire, followed by abstract thinking, of which the outcomes are best symbolized in the character Fire[火]. Because it is an abstract concept, it is hard to give a single and strict definition. Naturally, it would be necessary to analyze and illustrate the origin of 'Fire' from different angles such as broad definition, multi-definition, levels, classifications and effects. The concept of 'Fire' has four meanings in the aspect of the broad definition: first, natural fire; second, the physiological conception of fire; third, the medical conception of fire; fourth, general concept related to fire. In Traditional Chinese Medicine, fire mainly indicates physiologic fire, pathological fire, the fire in the six kinds of natural climate and the fire as one of the properties and the flavors of herbs.

The purpose of this study was to examine the effect of family-of-origin, personal and spousal characteristics, mediated by communication and problem-solving behavior, on marital quality and stability. On the basis of previous literature, the theoretical model was specified, estimated, and evaluated for adequacy of statistical fit for samples of 214 married women. Although the initial model was not supported by data, the revised model fitted the data adequately. Results of structural equation modeling indicated family-of-origin and communication behavior directly affected marital quality. However, the personal and spousal characteristics were linked with marital quality and stability only if they were mediated by communication and problemsolving behavior. Communication behavior was strongly related to marital quality and stability both directly and indirectly through problem-solving behavior. The model also showed marital quality can be an antecedent variable for marital stability. The findings of results is to generate more broad-minded thinking about how communication behavior, marital quality, and marital stability are interrelated.
