As the information-oriented society makes progress, the role of Image has much influence on human being in space as a medium for information delivery and a means of artistic communication. These influences are appeared as expressional characteristics of the image such as the reproducibility of reality and unreality in the real world, the synchrony of expression of time, visual formality, a sign and the transmission of moaning. For these, the investigator examined the meaning of image in aspace, taking into consideration of the interrelationship of image, space, and human being. As study findings show, the expressional characteristics of image in space have such visual effects as a space in which pictorial formality and object exists, in which the mutual understanding of communication exists, and that realizes immaterial membrane in the aspect of time and space, according to the electronic light, color, and formation of the image media. In addition, it become clear that the characteristic could be staged on various circumstances by constructing the relationship between an object and a point of time interactively with bidirectional communication through combining technology and art. This suggests that the image develops as the form of sensory communication via interacting of space and human being.

Elementary students are tend to depend heavily on visual informations in the cognitive process. Thus, elementary science textbooks provide science contents mostly by inscriptions, the visual materials, with little verbal information in the limited page area. Especially, since the textbooks include many accompanying inscriptions rather than a basic inscription, it is very important to understand the relationships among many inscriptions in teaching and leaning science. Therefore, this study analyzed the status and characteristics of accompanying inscriptions used. in elementary science textbooks, and classified them according to their functions. As results, we found six types of the accompanying inscriptions such as inner part, detail, result, process, emphasis, and explanation. Accompanying inscriptions were used more frequently in the lower grade (3rd and 4th grades) than the higher grade (5th and 6th grades). We discussed the examples of each type in detail, and thus revealed some possible difficulties in understanding inscriptions caused by the inconsistency of the directions of the basic inscription and accompanying inscription, and by the absence of the sign linking the basic and accompanying inscriptions.

As a means of overcoming the linguistic barrier between different languages in the Internet cyberspace, a sign-language communication system has been proposed. However, the system supports avatars having the same model structure so that it is difficult to communicate between different avatar models. Therefore, in this paper, we propose a new gesture communication system in which different avatars models can communicate with each other by using a FBML (Facial Body Markup Language). Using the FBML, we define a standard document format that contains the messages to be transferred between models, where the document includes the action units of facial expression and the joint angles of gesture animation. The proposed system is implemented with Visual C++ and Open Inventor on Windows platforms. The experimental results demonstrate a possibility that the method could be used as an efficient means to overcome the linguistic problem.

In this paper, we propose the digital video frame obfuscation method for intellectual property protection using the DC component of the intra frame and the motion vector of the inter frame at digital video encoding. The proposed method considers characteristics of the HVS (human visual system) which is sensitive at the low frequency and the middle frequency. This method makes the signal distorted as operating XOR between authentication signal and the DC coefficient of the intra frame including main information and the sign of the motion vector including edge motion, so that the video is normally displayed only when suitable authentication signal is applied.

The postmodern culture since the later 20C breaks downa tradition a relation between the reality and languages or sign images expressing it. It develops in the way to review the meaning on the object's imitation or the representation to have been followed since Plato and represent the new state and concept of expressed things. Also, The visual art leads an change of paradigm by images giving up the visual resemblance or the function of representation and endowing them with the new sense. This essay has a purpose to study an important discussion about this change centered on Baudrillard and Lacan. A sociologist Baudrillard promotes the concept of 'simulation' through detecting the reality and the social and historical state of the image. Studying on the course of this change, he calls the step that the image escapes from the stage to reflect the reality and become the pure imitation by itself simulation. The image in the stage of simulation is called 'hyperreality' because it doesn't have any an indicator or a substitute and happens by models without the original or the reality. So he asserts that art is not to contain some absoluteness or transcendency as the past, but to be as the spectacle with characteristics of meaningless, emptiness, contingency. Lacan dismantles the concept of the absolute Cogito to have become the center of the western ideology, and creates the concept of 'Other'. He concludes also the reality exists but can't be captured, and it's impossible for the thinking subject can reach it. The concept of new image which can be thought as the Symbolic in Lacan is 'Signifier without Signified' since it isn't possible to be the transcendent Signifier fixing the meaning finally in it. His 'Gaze' theory is which to be emitted in other's area determines the subject. Equally Baudrillard and Lacan sets up the new state of the image through the end of representation system As for Baudrillard, art intends to the worthlessness and is nothing but imagination. But in Lacan a picture represents the subject being in process by the dialectic of desire.

Purpose: The purpose of this study was to compare the grade of fatty degeneration and atrophy of rotator cuffs on immediate postoperative MRI to those on preoperative MRI in patients with rotator cuff tears. Materials and Methods: Seventy patients were included in this study, who received arthroscopic rotator-cuff repair and underwent both preoperative magnetic resonance imaging (MRI) and immediate postoperative MRI in our institution. Fatty degeneration of rotator cuffs and the atrophy of supraspinatus muscles were evaluated with T1 oblique sagittal images in the Y-shaped view. Fatty degeneration was evaluated using a Goutallier classification system, and the atrophy of supraspinatus muscles was evaluated using a modified tangent sign and a visual occupation ratio. Results: From 70 patients, a total of 100 tendons were repaired: 18, 69, and 13 tendons were treated for subscapularis, supraspinatus, and infraspinatus, respectively. The Goutallier grades (P = 0.012), modified tangent signs (P = 0.000), and visual occupation ratios (P = 0.000) of supraspinatus muscles were significantly decreased in immediate postoperative MRIs when compared to preoperative MRIs. In immediate postoperative MRIs, the Goutallier grades of supraspinatus muscles were decreased by one grade in 18.8% (n = 13) of the patients, and the atrophy of supraspinatus muscles was improved by one grade in 26.1% (n = 18) for modified tangent signs and 21.7% (n = 15) for visual occupation ratios. However, fatty infiltration by the Goutallier grades of subscapularis (P = 1.000) and infraspinatus (P = 0.157) muscles were not significantly changed after arthroscopic surgery. Conclusion: Immediate postoperative MRIs showed a significant improvement of fatty degeneration and muscle atrophy in supraspinatus muscles when compared to preoperative MRIs.

The study, "a semiotic analysis on 1930′s costume", is based on semiotic theory which analyze the meaning of signs. In the novels, "흙" and "삼대", character′s costume were used as a visual language that implies massages of character′s status, class, and the view of value. Analyzing the meaning of clothing signs, clothing could deliver the people′s informations to others and could be first things when people accept new value. The object of the studies are the novels, Hulk(흙) and Samdae(삼대) which are written by lee, Kwang-Soo and Yeom, Sang-Seob. In the novels, the social structure is classed as modern and traditional after we accept the western cultures and institutions. The traditional clothing, Han Bok, were dressed by the conservative woman. However, we could find the modernized woman dress with the western dress and the modified traditional style. According to the result of the research, we could find that clothing could be a sign which indicates value and also clothing is one of the first thing to change when people acquired new value.

It opposition to visual luxury of Post modern Architecture a new tendency characterized as 'simplicity' emerged in architecture. It seems clear that such a tendency so called Minimal Architecture has risen as a reaction to the surfeit of sign and the mixture of languages generated by postmodernism. This new simplicity is also related to the tradition of Modern Architecture and the Minimal Art Movement is 1960's. They adopted simple is also related to the tradition of Modern Architecture and the Minimal Art Movement is 1960's. They adopted simple primary Volume to avoid the main fluence on the already chaotic urban environment As a result a strong monumentality is achieved. The main interests for 'minimal' architects seem to be the making of simple structure and the repetition of modular elements to achieve an economic and efficient construction method. Transparent and honest expression is preferred instead of attaching another ornament skin on to the skeleton of the architecture.
