The purpose of this study was to investigate narrative structure and meaning structure of pictures In TV reporting. TV reporting consists of linguistic representation and pictural representation with which implicate specific meanings. In the past, the latter has been considered as a kind of added material to the former. But, todays, the latter has been considered more important than the latter in implicating specific meanings. Therefore, the author analysed pictures of TV reporting. Specifically, he selected KBS TV news coverage on '9 11 Disaster of U.S.' with various semiological research methods. Through this study, firstly, It was found that the pictural representation was organized with specific narrative structure applied for linguistic representation. Secondly, its meaning was more important than one of linguistic representation. Thirdly, its styles and structures tended to confine range, abstract and limitation of meanings presented by linguistic representation. Fourthly, images of the pictural representation could be interpreted with narrative structures of linguistic representation.

Since Adolf Loos' Ornament and Crime was released, ornament had been regarded as a vice in Modern architecture. In Post Modern architecture, the ornamental vocabularies extracted from the classical architecture have been symbolically expressed. As a result, the significance of existence of and the use value of architecture have increased with improved intimacy to the public. However, many studies that have analyzed architecture in terms of semantics and semiotics focusing on communication between architecture and the public have admitted instability in architectural meaning because of the fundamental difference between architecture and language. At the same time, the architectural representation has encountered a lot of limitations along with the deconstruction and non-presentation theory in Post-Structuralism. Even under these circumstances, the ornamental representation can be a critical factor which makes communication possible while expressing spatial identity in this pluralistic contemporary society. Hence, this paper has established logical grounds for research based on theoretical investigation on the concept of representation, semiotics, and ornamental representation, with regard to spatial communication through ornamental representation in commercial space. Based on Peirce's Semiotics which is the typical theoretical science in terms of representation, this paper has analyzed the three kinds of signs (Icon, Index and Symbol) that he proposed. Peirce's classification of signs becomes ideal when the factors are well balanced, with room for combination instead of strict classification. It appears that his theory of signs would be useful in understanding and analyzing ornamental representation. This study on representational ornament could offer a plan for ideal communication and abundant spatial experience in the interior design of commercial space in which the expression of creative space identity is required.

This study analyzed aspects of multiple intelligences related to rhythm, melody, understanding and representation of traditional Korean music. Subjects were 60 4-to 6-years-old children. Instruments were the Children's Korean Traditional Music (KTM) Ability Test (Park 2006)and Korean Multiple Intelligence Development Assessment Scale-My Young Child (MIDAS-MYC, Shearer, 1996). Data were analyzed by correlations and t-test. Findings were that (1) average scores on KTM rhythm and understandings were higher than melody and representation. (2) Traditional rhythm ability correlated most with linguistic intelligence. (3) Multiple intelligences by representation ability for KTM differed significantly in Linguistic intelligence and relationships to Naturalist, Musical, Logical-mathematical, Interpersonal, and Bodily-Kinesthetic intelligences.

Let q be a power of 16. Every polynomial $P\in\mathbb{F}_q$[t] is a strict sum $P=A^2+A+B^3+C^3+D^3+E^3$. The values of A,B,C,D,E are effectively obtained from the coefficients of P. The proof uses the new result that every polynomial $Q\in\mathbb{F}_q$[t], satisfying the necessary condition that the constant term Q(0) has zero trace, has a strict and effective representation as: $Q=F^2+F+tG^2$. This improves for such q's and such Q's a result of Gallardo, Rahavandrainy, and Vaserstein that requires three polynomials F,G,H for the strict representation $Q=F^2$+F+GH. Observe that the latter representation may be considered as an analogue in characteristic 2 of the strict representation of a polynomial Q by three squares in odd characteristic.

To the best of our knowledge, there is no method, in the literature, to find the fuzzy optimal solution of fully fuzzy shortest path (FFSP) problems i.e., shortest path (SP) problems in which all the parameters are represented by fuzzy numbers. In this paper, a new method is proposed to find the fuzzy optimal solution of FFSP problems. Kumar and Kaur [Methods for solving unbalanced fuzzy transportation problems, Operational Research-An International Journal, 2010 (DOI 10.1007/s 12351-010-0101-3)] proposed a new method with new representation, named as JMD representation, of trapezoidal fuzzy numbers for solving fully fuzzy transportation problems and shown that it is better to solve fully fuzzy transportation problems by using proposed method with JMD representation as compare to proposed method with the existing representation. On the same direction in this paper a new method is proposed to find the solution of FFSP problems and it is shown that it is also better to solve FFSP problems with JMD representation as compare to existing representation. To show the advantages of proposed method with this representation over proposed method with other existing representations. A FFSP problem solved by using proposed method with JMD representation as well as proposed method with other existing representations and the obtained results are compared.

Aesthetic consciousness of the body determines the form of clothing, reflecting the time and culture as well as the individual and society. Using 'body' to analyze the clothing form, my study develops a framework by which to classify the representation and non-representation of the body in fashion. Theoretically, this study draws from Jean Baudrillard's Simulation theory which maintains that simulation develops the whole edifice of representation. My study substitutes the successive phases of the image to that of (non) representing body in fashion. The correspondences between them are; first, 'image is the reflection of a basic reality' for the representation of physicality, second, 'image masks and perverts a basic reality' for the manipulation of physicality, third, 'image masks the absence of a basic reality' for the absence of physicality, and fourth, 'image bears no relation to any reality whatever' for the absence of body in fashion. Aesthetic ideal of the body is visualized in the form of a dress. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. My study suggests a framework to analyze bodily representation in fashion, focusing on the relationship between the clothes and body.

Let G(*) be a Borel function applied to a stationary long memory sequence {X$_{i}$} of standard Gaussian random variables. Focusing on the process {G(X$_{i}$)}, the present paper establishes the almost sure representation for the empirical quantile process, that is, Bahadur's representation, and for the empirical process with respect to sample mean. Statistical applications of the representations are also addressed.sed.

Data are numbers and texts, images, sound etc in real world. But, data is represented as a sequence of 1s and 0s in computer. It is very difficult that elementary students understand the concept of data representation through traditional lecture method. In this paper, we analyzed the software education curriculum of KAIE and selected contents of data representation education for the mid-grade elementary students. Also, we developed teaching- learning materials and multimedia contents for data representation education. The method proposed in this paper is expected to contribute to software education for data representation education.

An approximate representation of discrete functions {f$_{i,j}\mid$｜i, j=-1, 0, 1, …, N+1}in two variables by a fuzzy system is described. We use the cubic B-splines as fuzzy sets for the input fuzzification and spike functions as the output fuzzy sets. The ordinal number of f$_{i,j}$ in the sorted list is taken to be the out put fuzzy set number in the (i, j) th entry of the fuzzy rule table. We show that the fuzzy system is an exact representation of the cubic spline function s(x, y)=$\sum_{N+1}^{{i,j}=-1}f_{i,j}B_i(x)B_j(y)$ and that the approximation error S(x, y)-f(x, y) is surprisingly O($h^2$) when f(x, y) is three times continuously differentiable. We prove that when f(x, y) is a gray scale image, then the fuzzy system is a smoothed representation of the image and the original image can be recovered exactly from its fuzzy system representation when it is a digitized image.e.
