In this work is induced a new topology of solutions of chemical equations by virtue of point-set topology in an abstract stoichiometrical space. Subgenerators of this topology are the coefficients of chemical reaction. Complex chemical reactions, as those of direct reduction of hematite with a carbon, often exhibit distinct properties which can be interpreted as higher level mathematical structures. Here we used a mathematical model that exploits the stoichiometric structure, which can be seen as a topology too, to derive an algebraic picture of chemical equations. This abstract expression suggests exploring the chemical meaning of topological concept. Topological models at different levels of realism can be used to generate a large number of reaction modifications, with a particular aim to determine their general properties. The more abstract the theory is, the stronger the cognitive power is.

The purpose of this paper is to inquire into the significance of Euibangyoochui, Sejo Edition. One cannot study Euibangyoochui, Sejo Edition firsthand since it does not exist today. Instead, this writer looked into the process by which the Sejo Edition had been proofread and the historic figures who led the proofreading process. The quantities of the Sejong Edition and Sejo Edition have been compared, of which the meaning has also been studied. 1. The compilation of Sejo Edition began in 1459(5th year of Sejo), the year King Sejo entrusted the work of proofreading of Euibangyoochui to Yang Seong Ji. This was not a continuance from the work of King Sejong, but a whole new business ignited by the will and necessity conveyed by King Sejo himself. 2. King Sejo regarded medicine important and emphasized its practicality. The fact that the 365 volumes of the Sejong Edition was reduced to 266 volumes reflects the emphasis put on practicality. 3. Yang Seong Ji, who led the proofreading process, played an important role in managing state documents from the time of King Sejo. His compilation, Euibangyoochui, Sejo Edition, is a work that can be discriminated from its Chinese counterpart in that it had been proofread.

This paper Is to reconsider his architectural significance by understanding the role and moaning of the columns shown in the works of Mies. The reason of such an approach is to reflect the tendency to overlook the various significances of Mies's works as we interpret his architecture simply as a simplified work by abstraction. The process of simplification often neglects open interpretation so that it offers partial and unified cognition frame and causes remaking of closed meanings. It removes some possibilities of new interpretation for Mies's works. The study suggests that his columns are a medium to show the solid body transferring architectural significance in contrast to the immaterialization of body as transparency of modem architecture. It can be said that all the human cognition is usually made within the material limit of visibility and tangibility.

All kinds of artwork, including multimedia and digital image that has been subliminated into an af mediating two numbers 0 and 1 in recent age, are self-sufficient and autonomous in themselves. Nevertheless, each of those artworks can be realized as a real entity only if its appreciator is capable enough to explore some potential meaning out of it through his or her own perceptual work. According to Mikel Dufrenne, an artwork is composed of three existential tiers: "le sensible" or the sensible material; "fe representation" or the subject(le sujet), and "1′expression." Dufrenne contends that our esthetic perception can be realized by way of three steps that are comparable to those three tiers: perception of the presence of the body("le sensible"), contemplative perception by way of imagination("le representation"), and reflective perception ("1′expression") as a result of dialectics of sense and sensibility. This paper argues on the aesthetic perception with regard to digital image expressed by two numbers 0 and 1, putting focus on the epistemological role of sensibility(감) that explores "1′expression" a la Dufrenne.

The book number, among various steps of book processing works, needs more careful attention and better-organized knowledge, and it is more sensitive than other parts of cataloging. This paper will give some suggestions on ways of constructing a book number, including the definition and the types of edition indication within a book number, and analyse some problems related to their application into real situation. Three possible ways of edition indication with in a book number were explained, and examples were given for each of them. Problems occurring when these codes were applied to books were analysed. In addition to the generally recognized meaning of the book number as a mean of differentiating similar works, the edition indication can make it possible for both the library staffs and the users to identify the characteristics of a work only with the book number. Searches for mere convenient and effective ways of edition indication might be related to the cost-effectiveness of book processing, and of library operation.

Emthusiasm about the introduction of computers into mathematics education is widespred. But, the perspectives about the relationship between mathematics education and computer are diverse. The purpose of this study is to examine theoretical background for using computers in mathematics education. In spite of the pedagogical possibilities of computers. only a small minority of mathematics teachers are using computers in mathematics classroom. It is natural to seek this obstacles within theoretical background of the teachers who manage computers, In this study, We discuss the problems in the two sides. First, due to increased computer activity, relationship of mathematics in school with mathematics in society is changing. It is tension between academic mathematics and practical mathematics. School mathematics have to be changed toward stressing practical mathematics. Second problem is the dialectical relationship between the individual and the collective. While maintaining a respect for the individuality of student contributions. We take into account the social dimension of mathematical meaning-making. We discussed theoretical clarification of work collaborative learning. We propose the case study for the roles of computer in collaborative mathematics learning.

When multiple robotics systems with several sub-chains grasp a common object, the inherent force redundancy provides a chance of utilizing internal loading. Analysis of grasping space based internal loading is proposed in this work since this method facilitates understanding the physical meaning of internal loadings in some applications, as compared to usual operational space based approach. Investigation of the internal loading for a triple manipulator has been few as ,compared to a dual manipulator. In this paper, types of the internal loading for dual and triple manipulator systems are investigated by using the reduced row echelon method to analyze the null space of those systems. No internal loading condition is derived and several load distribution schemes are compared through simulation. Furthermore, it is shown that the proposed scheme based on grasping space is applicable to analysis of special cases such as three-fingered and three-legged robots having a point contact with the grasped object or ground.

This study is on the aesthetic characteristics of Balenciaga design succeeded to by Nicolas Ghesquiere, and tried to understand his pursuing brand's new design concept and aesthetics. The three key characteristics of Balenciaga designed by Nicolas Ghesquiere are Retrospecitvness, Eclecticism, Deconstruciton. First, Balenciaga looks retrospective sense through reinterpreting tradition. Nicolas created a new sense of expression by mixing his proper instinct with Balenciaga's original properties, historical components of the past western dress, and various design elements of assistants who used to work in Balenciaga. Second, Balenciaga expresses uncertain meaning by compromising between contrast and synthesis among the past and the future, the males and the females, simple and ornament, or different styles. Third, Nicolas's experimental and outsider-oriented view of Deconstruction through reorienting of thought is considered a try for a new formative concept as a designer who is not limited by general rules.

The Ewha Music Database (EMDB) is an online database comprised of primary source materials related to music education from East Asia during the modern era (1880 to 1945) when Korea, Japan, and China were geopolitically and culturally intertwined. We developed the incipit search in EMDB as an embedded tool. This is the first attempt in Korea to implement a unique search function of musical data using alphabets of musical notes. Unlike in traditional search system that uses general literature information search conditions, such as author, title, publisher, year, number of pages, etc., it offers a new way of searching a musical piece/work and sheet music. This study confirms that digital information technology is an important methodology for research of music culture as a field of humanities.

Scandinavian countries have hold tradition shared historically and culturally in common, brought the weighty traditional thoughts enabled to develop their unique culture. Since 1940s, Scandinavian design could pervade with affectionate forms and practical effectiveness with worldwide popularity. It was brought by creation of new and useful forms for the convenience in life, functionalism but not bounded by fashion of it. This study tried into the meaning of their history of modern furnishings design based on the development background of furnishings design, its trends, designers and their work focused around Sweden, Finland, and Denmark. Scandinavian furnishings is a functional furnishings reconciled to natural material and human life exactly correspond to the taste of the generation unrestricted from the tradition of contemporary and compact design preference or classic favored preference. The practicality and exquisite techniques of Scandinavian furnishings lies within the realm of possibility for studiously love of the world.
