시대와 문화마다 사용되는 문자와 그것을 표현하는 도구가 다르게 나타나지만 공통적인 특징은 의사소통과 기록을 그 목적으로 한다는 것이다. 그리고 원활한 의사소통을 위하여 시각화시킨 글자는 연상을 통해 특정적인 상징의 의미를 떠올리게 되고 시각화시킨 도구 또한 이미지 연상에 영향을 끼치게 된다. 본 연구에서는 글자를 시각화시키는 캘리그라피의 표현도구가 글자의 형태를 벗어나 도구 자체로써 수용자에게 어떠한 이미지를 연상시키는지 알아보기 위하여 진행되었다.

This paper explored the effect of using eye gaze pointer in addition to the hand gesture visual communication cue in remote collaboration. We recruited 24 participants and conducted a user study comparing two conditions: (1) only hand gesture visual communication cue, and (2) eye gaze pointer with hand gesture visual cue. The results showed that the added eye gaze pointer cue reduced the workload and increased the co-presence when using it together with hand gesture cue.

This study investigated the effect of visual mathematics education using smartphones and immediate feedback through SNS on students' understanding of basic mathematical concept and academic achievement at the tertiary level. Researchers analyzed the test results of 214 students' mid-term and final examination in 4 classes consisted of 16 weeks' classes with two hours per week. Also their 30 questionnaire survey results were analyzed. The result reveals that classes using smartphones promoted understanding mathematical concepts and induced students' motivation and affirmative reaction. This study implies that an appropriate use of technology will support dynamic visualization of mathematical modeling and its interpretation, which enables students' active participation and deeper understanding.

In line with the development of Media, the use of character has been developed in various ways. Specially, it has been emerged the functions of written language of visualization and delivery of emotion in the digitalized environment due to speedy growth of internet and Mobile. The emoticons emerged as a tool for the convenience of communication proved to have taken effective role in the part of communication culture. Particularly, Hangul emoticons which contains the meaning of communication and sharing in tandem with the principle of Hangul invention, provides convenience in combination & use due to its structural and design characteristic for which it plays a significant role of visual element. Hangul emoticon is definitely a part of Hangul culture and in view of globalization of visual language in connection with media development, there is a huge potential being to be used as a international communication tool. In this study, it will be reviewed on the increased utilization of Hangul emoticons and related public issues as being a part of typography media, in view of the generalization of private media as well as change of subjective user.

The purpose of this essay is to converge the theory of communicative action Into the new paradigm of 'public relations democracy.' The notions of communicative action rationality, the public sphere, and deliberative democracy led new public relations paradigm approaches including meaning sharing, media access enlargement, and theoretical ramifications for the powerless. As Habermas prospected the power of comprehensive rationality to solve post-capitalist problems, the paradigm of public relations democracy visions the new era of public relations equipped with rhetorical and critical approaches. The new paradigm tries to overcome functional fallacy and embraces the concept of public interest. The paradigm of public relations democracy aims at integrating all three levels of public relations activities such as individual, organizational, and social levels, and pursues to enlarge the public sphere through increasing communicative actions and resolving social conflicts. Habermas's critical theory exhibits an opportunity for public relations theory building.

The posters are the tools to communicate authors' idea with others by visual image and a little word. Every discipline has its own sign with specific meaning shared by the members of the discipline. Chemists and students learning chemistry, therefore, will communicate with each other by specific chemical signs (codes). The Korean Chemical Society has held the feast of drawing chemistry posters by students nationwide since 2004. In 2004 and 2005, more than three thousands of posters were submitted, and about one hundred and fifty posters were selected as the prize winners. The award was divided by the grade levels of elementary, middle, and high school. This study explores the codes of chemistry used in students' posters. With the analysis of the visual elements and the verbal elements of posters, 7 chemical codes were found such as the liquid, the experiment apparatus, the graduations, the chemical language, scientists, the earth and environment, and things around us. In addition, the differences were investigated on the grade levels, on awarded or non-awarded poster, and on the years. Educational implications of these findings are discussed.

자막은 자막을 볼 수 있는 모든 사람들의 정보전달, 의사소통을 할 수 있는 유용한 도구로 사용 되고 있지만 자막은 평범한 텍스트로 있어 자막에서 강조된 부분, 감정 등을 전달 할 수 없다는 단점을 가지고 있다. 그러므로 청각 장애인들은 해당 컨텐츠의 감정, 강조 되는 부분을 알 수 없어 대화의 숨은 의미가 다른 방향으로 이해 할 수 있다는 위험성을 가지고 있다. 본 논문에서는 음성을 텍스트로 변환하는 STT(Speech To Text)를 이용하여 동영상 스트리밍 서비스를 실시간으로 음성을 텍스트로 변환과 동시에 강조하는 부분까지 개발하여 청각장애인 입장에서 기존 자막보다 효율적인 시각적 효과를 주는 미디어 접근을 위한 동영상 스트리밍 자막 서비스를 개발하고자 한다.

This study analyzed the visual images covering 'weather' and 'weather forecast' in elementary science textbooks from the Syllabus Period to the 7th national curriculum from the socio-semiotic perspective. The results showed that most of the visual images were 'realistic' which were descriptive of real world phenomena. This means that most of the visual images in elementary science text were familiar to students in every curriculum period. The power relationship in communication between images and students was very complex. The visual images in elementary science textbooks include few geometrical and alphanumeric code in every curriculum period. This study provides a new framework to interpret amount of information, functions of information, structures, and social meanings of visual images. It could be also a beginning stage to introduce the socio-semiotic perspective into choosing visual images for next science textbooks.

When restoring their anterior dentition, patients become more demanding on esthetics compared to posterior region during treatment planning phase. Digital Smile Design (DSD) procedure is performed in presentation software and digital photographs. This can widen diagnostic visualization and aid in transferring information between clinician, patient, and technician. This case presented is that of patient with dissatisfaction of his anterior old restoration. Retreatment procedures were carried out in two different manners: (1) using DSD protocol for diagnosis, smile simulation, communication and fabricating interim and definitive prosthesis by totally digitized workflow. (2) Using diagnostic wax-up for smile design and fabricating restorations by conventional workflow. Comparing two methods, DSD was easier to communicate between the dental team than the diagnostic wax-up method. But the final result obtained failed to meet total esthetic factors. Therefore, to obtain predictable esthetic results, more advanced design tool would be needed, including consideration of various esthetic factors besides successful communications.

Electronic BBS (bulletin board system) Ins been widely recognized as an appropriate medium for exchanging ideas and sharing information asynchronously. The communication ability if BBS is the main reason for utilizing it as a tool for collaborative learning. Researchers in the community reported a number if findings regarding the educational utilization if BBS recently. In this paper, we propose a qualitative method to measure communication activities using BBS so that the complex discussion behaviors of participants can be understood analytically. We propose characteristic vectors to describe discussion behaviors of groups and individuals, which can be conveniently used for characterizing and comparing discussion groups as well as individuals. The interactivity model representing interactive activities shows graphically the degree of inter activity if discussion groups as well as individuals. Also, time dependent measurements are investigated to analyze discussion activities with time. Experiments on the proposed measurements conducted on the Web-based discussion project using BBS demonstrate how measurements can be carried out, how characteristic vectors and inter activity model can be constructed and used.
