Mathematics is constructed by many signs, and learning mathematics involves the understanding and uses of them. This study reflects mathematical signs and their meanings, and considers how they can be introduced in learning. For these, we first investigated epistemological positions as Piaget, Vygotsky, anthropology, and interactionism. And we investigated semiotic models that Saussure and Peirce built each. Among these we adopted Peirce' triadic model that is consisted of interpretant, object (referent), and represen tamen(sign). In mathematic learning process, representations are transformed by translations and meanings are growed to the representation of another sign. And the meaning of sign grows by learner's interpretation. In terms of theoretical grounds, we settled that the understanding of mathematical signs involved the understanding of their representations and their meanings. On the foundation of above contents, we searched how we introduced signs to students and there were methods that approached to students representationally or inquiringly.

Semiotic studies in mathematical education have been based on Saussure, Peirce, and Frege and many prior researches have explored the concepts in a perspective of semiotics. However, the relationship among semiotical elements and the formation and the evolution of a conception are still ambiguous and veiled in many aspects. This thesis is intended to show how a conception was formed and evolved by expression, which is an element of semiotics. In this process, I sought to partially illuminate the relationship among expressions, concepts, and objects.

Flagship store has rapidly come into being is the typical tool of brand-communication between enterprises and consumers. Flagstore comprised of a lot of tastes delivers brand-image and builds brand- identity. this research on the ground of Semiotics by Pierce, examined closely the connections between two tastes and analyzed the brand-image had prodused through tastes. The method study restricts the four analytical subjects of the fashion-brands have successfully built brand-image and identity and arranges each brand - identity and constructive strategy. After that, it analyzes the examples of Flagstore on the ground of Semiotics. The purpose of this research focuses how the tastes will have occurred on the Flagstore will express and analyze the brand -identities and presents a methodology it will be able to designe.

Vesely explains, the main source of our confusion and nihilism comes most probably from the ambiguous relationship between modem architecture, technology and aesthetics. Also, to overcome such crucial problems, many theorists recently emphasize to take part in cultural civilization and to preserve creative genes of great culture that is based on our interpretation of 'ethical and mythical nucleus of mankind,' rather than in technical modernization that constitutes a sort of subtle destruction of mytho-ethical nucleus of a society. They for architecture also strongly stress on a mythopoetic imagination and an ontological construction of building, which could make a form symbolic and mythical rather than mathematical and aesthetic representation. On this point, 'myth' becomes a vital idea for constructing and construing architectural form and space. And it is also one of the essential concepts to understand both the motive power of cultural continuation of place and the meaning of architecture. Nevertheless, its meaning and the citation of word in architectural essay are still obscure. It might be because the original concept of myth not only has been lain in the matter of philosophical contemplation. Thus, the intention of the research is focused on lightening the meaning of myth in architectural term. Especially, it is, first, concentrated on interpreting philosopher Ernst Cassirer's reflections which were written in order to emphasize the importance of 'mythical consciousness' for the world's cultural civilization. And, the second, it will continue to interpret the myth as a sign within the semiotic concept of Charles Sanders Peirce, and further to emphasis the significance of mythic signs for the continuance of artistic and cultural idea including architecture. The contents of the paper is not that of architectural planning and design methodology, rather architectural philosophy and epistemology. Nevertheless, in regard to architecture, the research will, against today's un-discriminated use of symbolic motifs and instrumental representation of form, suggest a concrete architectural and aesthetic theory of myth and sign, especially of the relationship between the idea of semiology and the function of cultural continuity.

What are the meanings of abduction as a methodology of Cultural Studies? By contextualizing Charles Sanders Peirce's logic of abduction in the discipline of Cultural Studies, I explore the epistemological discussion on the modern scientific research methodology of social sciences. Abduction is a kind of logical inference, which is often associated with guessing or intuition. Peirce's method of abduction and Cultural Studies' contextual formation in effect address an alternative methodology to positivism. Criticizing the modern Eurocentric structure of knowledge construction, I suggest that the virtue of abduction, as a logic of discovery, should be re-discovered in the context of Cultural Studies. Abduction holds important lessons for Cultural Studies as well as social sciences in general because of its focus on intuition, empathy, and intellectual collaboration. Through its elaboration of the logic of abduction, Cultural Studies is able to maintain not only its epistemological ground but also its methodological communicability.

The purpose of this study was to design a 'Form of Abduction' which is the 'guide form used in generating hypothesis through abduction', and to analyze the features of the hypotheses generated with the 'Form of Abduction' compared with those generated without any special guide form. Through a review of Peirce's literature regarding the meaning and frame of abduction, a 'Form of Abduction' was designed as a three step format as follows: (i) writing down what is doubted, (ii) wiling tentative explanations which replace what is doubted with what is believed, (iii) writing the tentative explanations as hypotheses. The thirty four pre-service elementary teachers were asked to generate hypotheses without a 'Form of Abduction' at first, and then were asked to do so again using the form. The results of analysing the features of the hypotheses were as follows: in the case of using a 'Form of Abduction', firstly, the types of misunderstanding or mis-adapting the meaning of hypothesis were found to be rare, and secondly, the types of 'giving explanation about the cause of problematic situations through analogical inferencing from the existing knowledge' were found to be double the rate of when no special guide form was used. In conclusion, the hypotheses generated with the 'Form of Abduction' had the features of satisfying the original meaning of hypothesis, i.e. 'explaining the cause of phenomenon and leading to knowledge expansion'. These results also showed that using a 'Form of Abduction', although its form was simple, could be a way of helping students generate hypothesis properly in science classes.

This research is to investigate the way to combine Peirce's typology of signs with architectural design. A new diagram is suggested to ensure the continuity of Peirce's typology, by rearranging and reconstructing the well known inverted triangle diagram showing the structure of the typology. The new diagram is easier to understand the organization of the typology, by showing the linkages between sign types and their relationships with other types. A way to adapt the new diagram to architectural design for the purpose of representing typology as well as ensuring model growth as semiotic model for architectural design model. The new model is organized of three sign clusters, sinsign cluster, legisign cluster, and symbolic cluster. They are interrelated through successive inclusion and case inclustion. The new model is organized of threefold layers. The first layer is internal structure of each cluster. The second is interrelation between cluster. The third is mediation of symbolic cluster between sinsign cluster and legisign cluster. This paper investigate and demonstrate the possibility of adaptation of the new model in architectural design. It has been argued that the theoretical basis of sign typology is adaptable to architectural design by principle. More future research issues are discussed.

In the single yarn spinning process by the ring spinning system, the finer the fineness of yarn and the lower the twist coefficient, the lower the breaking strength and breaking elongation. The change of yarn specific volume to yarn number agreed with Peirce's formula in the range of Ne 50 to 70, but above that range the values of the experiment are higher than that of the formula. The change of diameter of yarn to the reciprocal of the square root of yarn number agreed with Peirce's formula in the range of under 0.14, but above that value the values of the experiment are higher than that of the formula. In breaking strength variation according to twist constant of single yarn, as the twist coefficient increased, breaking strength increased. At 5.8∼6.0 of twist coefficient the maximum breaking strength was shown, but above that value breaking strength decreased. Breaking elongation also showed a similar tendency. But at 6.0∼6.5 of twist coefficient the maximum breaking elongation was shown. Also spinning tension increased as twist coefficient increased. Twist coefficient, breaking strength and breaking elongation according to the number of coils stayed almost the same. Yarn spinning tension according to the number of coils at the maximum of diameter was the lowest value. The speed of the traveller at the maximum of diameter was the highest value.

The purpose of this study is to analyze story generation model of blogging. This study considers the structural factors like RSS, Trackback of the blog that generate stories. RSS pushes stories and this makes 'Story Unit'. By contrast, Trackback pulls stories and this makes 'Story extension'. By applying the concept of C. S. Peirce's "interpretant" for analysis process of story generation, story transformation, and story circulation on a blog, this study examines the meaning that each process create. This study suggests the process of story generation model on blogging as an integrated symbol and presents the model in storytelling perspective.

The purpose of this study is to investigate theoretically the meaning and features of the Community of Inquiry (CoI) based on the views of Peirce and Dewey, and to explore the implications of CoI in science education. The meaning and features of CoI are: (a) inquiry in CoI is initiated with faithful doubt; (b) inquiry in CoI finishes with faithful belief; (c) inquiry in CoI attempts to find out the best explanation and solution regarding the practical effects of objects; (d) as an ideal community, CoI is required to be one that inquires continuously without definite limits; (e) as an actual community, CoI requires its members' open communication to find the best explanation and solution. Based on these features of CoI, the Community of Inquiry in Science Classroom (CoI-SC), "the classroom community for the purpose of transforming the state of faithful doubt into the state of faithful belief, in relation to natural phenomena or objects, and where the members share objectives as participants continuously attempt to find out the best explanation and solution by open communication, considering fallibility and the practical effects of objects", was suggested. The condition for implementation of the CoI-SC, "'interest', 'openness', 'rigor', 'fallibilism', 'participation', 'inquiry without definite limits'", were also suggested. Finally, several suggestions for the science curriculum were given.
