Currently the time when we are living the large majority is harmonizing with digital medium together. From the calligraphy which is traditional in the example is reconstituted with digital and with the element which is one design is being born again. This about one being time is not a fun in rediscovery and as the design where the traditional form which seems hardly is modern is mixed in digital medium and is going. In this paper when digitalizing the expressive technique of calligraphy from the work which is analog time knows the important element of the actual conditions which appear and the report person does. The ink which appears from joke from actual work or calligraphy technique analyzes the actual condition spreading and this digitalization at the time of height boil time.

종단간 전송 지연은 시각 동기, 네트워크 성능 측정 등에서 매우 중요한 요소이다. 그러나 IP에 기반하고 있는 Internet은 여러 통신망 상의 지연 요소를 정확히 전달할 수 있는 구조가 없기 때문에 종단간 전송에 있어 전송 지연을 정확하게 알 수 없다. 특히 UDP 네트워크의 경우 전송할 때와 수신할 때 경로가 같지 않기 때문에 일반적으로 일주 지연 시간을 이용하지만 각 편도 전송 지연 시간 차이는 시스템의 다른 요소에 대해서 오류 요소로 작용할 수 있다. 본 논문에서는 일주 지연 시간을 전송시 지연 시간과 수신시 지연 시간으로 따로 측정 분석하였다. 측정 결과 편도 전송 지연 시간 차이 값은 수십 밀리초 범위를 가지며 이는 NTP 등에서 시각을 동기화 할 때 통상적인 정확도, 수 밀리초를 훨씬 넘어선다. 이것은 편도 지연 시간 차이값이 시각 동기, 네트워크 성능 평가 등에서 중요한 오류값으로 작용한다는 것을 의미한다. 분석 결과를 실험 데이터에 적용할 경우 실제 편도 지연 시간에 근사한 값을 구할 수 있고 좀더 정확한 시각 동기, 네트워크 성능 평가가 가능하게 된다.

In web environment, we accept most of useful information visually. Icon is a channel through which we explore information, and we need icon design to deliver information clearly and quickly to users who accept information visually. Studies on icon have been carried out vigorously according to system environment, styles and characteristics of users. This study is on the metaphor icon, and judging from the characteristics of metaphor icon, it is by the phenomena of user's association of ideas. Divide metaphor and simile and analyzed metaphor icon that is searched in World Wide Web to distinguish similarity in metaphor icon special qualify, And I clarified the present condition of cognition by questionnaires asking people if they recognize the function. I also clarified if elements of icon design influence the level of user's cognition by visually comparing icons. The result of comparative analysis showed that different elements make different level of user's cognition, and to objectify it more, I made up questionnaires about elements of icon design and proved it again. To summarize the result of this study, the similarity between function and elements of design increases the level of recognition of metaphor icon proportionally. To improve user's cognition, I suggest designing with elements which materialize functions.

The study on the analytical and productive methodolgy of visual culture contents is meaningful because cultural contents are regarded as a national growth industry. The fundamental notion of cultural contents is researched based on the notion of visual culture, and important factors of the fun are analyzed as a creative motive of visual culture contents. So this paper provides anaytical methodologies for the fun in visual culture contents, which are based on semiotic theories of Charles Morris, Roland Barthes and Roman Jakobson. These analytical matrix can be references for the study of the mechanism of fun and the basic theory for using fun effects in the visual culture contents.

We propose a new Interet time synchronization model using danamic linear model and introduce the characteristics of internet transmission delays. SNTP(Simple Network Time Protocol) has been widely used as a time synchronization method on the Internet. While SNTP provides a very simple usage, SNTP may not provide the stable services, since SNTP does not consider the several essential error factors. In order to overcome the instabitily of SNTP, we analyze the process of time estimation of SNTP and find the difference between forward transmission delay and backward transmission delay operates the main error on the estimation of an time offset.

Recent complex visual culture is the visual world widely magnified according to the images like image, graphics, photograph, movie, and television, etc. by the development of digital technology. Because it conveys meanings and contents inserting sound and letters, it may have multimedia character conveying and communicating information beyond general language and letters. The vision for various images at that time is inseparably connected with language. And imaginative order of image and vision are composed of special way in culture and history. Language is different in society, culture, and history. Accordingly, if visual experience is communicated with language partially, it is difficult to have university. So, role of linguistic order plays an important role in forming and defining the social and cultural differences among the visual systems. Historically various visual and optical devices with this visual language have influenced a lot. These visual technologies are concrete and physical practice determining a way to get together with the subject and the visible object in the visible world. The visual language is connected with dimension like these symbols of images and the dimension like visual technologies to series of historical physical and institutional practices. It determines social visual mode toward object world in one of visual system. Accordingly, this study is to understand visual language with social and historical character according to the changed concept and characters as development of media technology. And it is to explain it in view of visual language as a dimension of symbol and visual technology of institutional and physical practice. After all, it cannot explain the effect on the function and visual mode of visual technology as its technical element only. It also cannot separate with the practice with coherent discourse and the physical and institutional practice. The possibility, technical element of technology contains, does not realize as it is but the effect is always communicated in the social veins and realized with a restriction.

Virtual worlds have pursued reality as if they actually exist. In order to evaluate the sense of reality in the computer-simulated worlds, several subjective questionnaires, which include specific independent variables, have been proposed in the literature. However, the questionnaires lack reliability and validity necessary for defining and measuring the virtual realization. Few studies have been conducted to investigate the effect of visual factors on the sense of reality experienced by exposing to a virtual environment. Therefore, this study was aimed at reinvestigating the variables and proposing a more reliable and advisable questionnaire for evaluating the virtual realization, focusing on visual factors. Twenty-one questions were gleaned from the literature and subjective interviews with focused groups. Exploratory factor analysis with oblique rotation was performed on the data obtained from 200 participants(females: 100) after exposing to a virtual character image described in an extreme way. After removing poorly loading items, remained subsets were subjected to confirmatory factor analysis on the data obtained from the same participants. As a result, 3 significant factors were determined to efficiently measure the virtual realization. The determined factors included visual presence(3 subset items), visual immersion(7 subset items), and visual interactivity(4 subset items). The proposed factors were verified by conducting a subjective evaluation in which participants were asked to evaluate a 3D virtual eyeball model based on the visual presence. The results implicated that the measurement method was suitable for evaluating the degree of the virtual realization. The proposed method is expected to reasonably measure the degree of the virtual realization.
