Foods are cultural texts. Recipes, cultural peculiarities, and relationships between people. Foods can expand into narratives. This study will compare and analyze the characteristics of the Korean - Japanese visual texts, and . The aim of this study is to examine the between-space and gender, and to examine the universality and specificity of the text of Korean - Japanese image culture. If the movie reproduces the world of reality fictionally from the viewpoint of the between-space, it can be seen that the artistic has differentiation by realistically reproducing the fictional world, but universally creates the hyper reality. Second, in the dimension of gender, both images suggest universality in which the dissolution of sex role becomes paradoxical product. However, has differentiation from the fact that it presents the aspect of gender equality more specifically.

Today we always can take a picture and enjoy it anywhere and anytime with a propagation of digital camera and camera phone. Even though the amount of digital picture content produced in every day life has been increasing, the way of enjoying it was just with phones or PC monitors. A small size screen of a cell phone and a desktop monitor are not suitable environment for enjoying digital picture, so the new market for digital photo frame has been opened. Until now, various kind of digital photo frames of many manufactures have been released for several years, but they have similar interaction way each other due to the limitation of their hardware specification so don't fill the intuitive mental model that users have about the product called a photo frame. Thus, this research aims to suggest an interaction way of digital photo frame providing with better usability and emotional satisfaction according to the spatial environment that it's located and users' behaviors.

A semiotic approach to modern visual arts has emerged since French post-structuralism was introduced to Anglo -American academics by "deconstruction" or "postmodernism." It views a work of art as a sign, which is its methodical assumption ana at the same time makes its application more accessible In the milieu of modern visual arts'effort to be intimate to with general audience, modern art photography is now faced with the request to be a familar and universal domain instead of being left only in photo books as artistic and academic achievements More specifically, various photo images 1mm such visual media as newspapers TVs, and computer graphics to such megaexhibitions as "Gwangju Biennale," "Media City Seoul," and "Pusan International Art Festival," are main objects of s030y. A coherent and scientific analysis of visual semitotics is still on the way; however, it is an urgent task how to read and interpret a photo image with multiple meanings This study argues that visual semiotics can be a powerful tool to enhance the understanding of art photography. After all, semiotics is a product of age; we live in the age of legibility, that is, of reading the work of art well as the social events and phenomena.rk of art well as the social events and phenomena.

As marine accidents happen frequently, it is required to establish a marine traffic monitoring system, which is designed to improve the safety and efficiency of navigation in VTS (Vessel Traffic Service). For this aim, recently, X-band marine radar is used for extracting the sea surface information and, it is necessary to retrieve wave information correctly and provide for the safe and efficient movement of vessel traffic within the VTS area. In this paper, three different current estimation algorithms including the classical least-squares (LS) fitting, a modified iterative least-square fitting routine and a normalized scalar product of variable current velocities are compared with buoy data and then, the iterative least-square method is modified to estimate wave information by improving the initial current velocity. Through several simulations with radar signals, it is shown that the proposed method is effective in retrieving the wave information compared to the conventional methods.

This study was to evaluate the usability of self-developed phantom for evaluating automatic exposure control (AEC) using three-dimensions (3D) printer. 3D printer of fused deposition modeling (FDM) type was utilized to make the self-developed AEC phantom and image acquisitions were conducted by two different type of scanners. The self-developed AEC phantom consisted of four different size of portions. As a result, two types of phantom (pyramid and pentagon shape) were created according to the combination of the layers. For evaluating the radiation dose with the two types of phantom, the values of tube current, computed tomography dose index volume (CTDIvol), and dose length product (DLP) were compared. As a result, it was confirmed that the values of tube current were properly reflected according to the thickness, and the CTDIvol and DLP were not significantly changed regardless of AEC functions of different scanners. In conclusion, the self-developed phantom by using 3D printer could assess whether the AEC function works well. So, we confirmed the possibility that a self-made phantom could replace the commercially expensive AEC performance evaluation phantom.

Various properties of digital covering spaces have been substantially used in studying digital homotopic properties of digital images. In particular, these are so related to the study of a digital fundamental group, a classification of digital images, an automorphism group of a digital covering space and so forth. The goal of the present paper, as a survey article, to speak out utility of digital covering theory. Besides, the present paper recalls that the papers [1, 4, 30] took their own approaches into the study of a digital fundamental group. For instance, they consider the digital fundamental group of the special digital image (X, 4), where X := $SC^{2,8}_4$ which is a simple closed 4-curve with eight elements in $Z^2$, as a group which is isomorphic to an infinite cyclic group such as (Z, +). In spite of this approach, they could not propose any digital topological tools to get the result. Namely, the papers [4, 30] consider a simple closed 4 or 8-curve to be a kind of simple closed curve from the viewpoint of a Hausdorff topological structure, i.e. a continuous analogue induced by an algebraic topological approach. However, in digital topology we need to develop a digital topological tool to calculate a digital fundamental group of a given digital space. Finally, the paper [9] firstly developed the notion of a digital covering space and further, the advanced and simplified version was proposed in [21]. Thus the present paper refers the history and the process of calculating a digital fundamental group by using various tools and some utilities of digital covering spaces. Furthermore, we deal with some parts of the preprint [11] which were not published in a journal (see Theorems 4.3 and 4.4). Finally, the paper suggests an efficient process of the calculation of digital fundamental groups of digital images.

The purpose of this study was to observe the current consumption of bedding products, purchase behavior, and to compare between purchase criteria and degree of satisfaction after the purchase. Independent variables are age, consumer's knowledge and involvement about the bedding materials. This study can contribute for bedding product marketing strategies and design development. We used questionnaires that were distributed to 500 females aged in 20s to 50s, using stratified sampling method. Only 457 reliable questionnaires were selected for statistical analysis. Data were analyzed statistically through frequencies, paired t-test, ANOVA, Dunnett T3, Chi-test, using SPSS (Version 12.0). The results of this study are as follows. The types of bedroom was significantly associated with age variables. Women in 20's to 30's were using the mixture of Ondol and bed(chimdaie), while 40's to 50's women were using bed for all their rooms. The usage of filling material for the comforter(ibul) was significantly associated with the age group. 20's to 30's age group preferred synthetic fibers for the filling, while 40 to 50's women preferred cotton fibers. Generally, the most of people used quilted comforter and they used cotton material as filling materials of comforters. As to purchase behavior, the most frequent place of purchase was specialty store of bedding products, and the highest percentage of motivation for purchase was "deformation after the use/throwing away". Purchase motivation for bedding was related with the age variable and the clusters based on the knowledge of bedding materials. We analysed the comparison test purchase criteria and satisfaction. In all attributes except brand image, people evaluated lower in satisfaction after purchase than in criteria before purchase.

Recently various electronic books (I-Book) based on PDA (personal digital assistance) that we can easily use anytime and anywhere have been developed. Volume and weight of the E-Book is much less than that of traditional books. In that reason, it is easy to carry and serve us with contents by diverse functions such as searching, bookmark, dictionary, and playing of color image, sound or moving picture. On account of these advantages, many products connected with I-Book have been emerged in the market. However a product connected with educational contents is scarce, because it requires not only normal function but also additional functions such as a problem solving. Therefore it is actually necessary to develop a browser and an editor for educational contents. In this paper, we express educational contents by XML and define structure of document with XML schema. Then, we design and implement an editor and a browser that can manage educational contents on PDA.

For practical education, many practices using various practical equipments have to be provided to students. In this study, the application of learning curve to represent student's learning process in a practical education using a equipment was studied. Learning curve model was originally developed in production management and based on human performance in human factors aspects. In this study, the application of learning curve model was studied on the eye tracking system, which is used to evaluate the usability of a product in design area. As a case study for its applicability, practical education for eye tracking system was provided to three students and then task completion times were measured for hardware system setup and gaze image recording. Learning curves were estimated for two tasks and then task completion times were predicted using the learning curves. Through ANOVA(analysis of variance) and correlation analysis, the applicability of learning curve to practical education was analysed. As the result, learning curve could be effectively applied to practical eduacation using equipment.
