최근 들어 핸드폰이나 PDA 등 휴대용 단말기의 보급이 급격히 늘면서 이를 통한 미디어 감상의 수요는 많이 증가하였다. 또한, 멀티미디어 기술의 발전 방향도 기존의 단방향 서비스를 벗어나 사용자의 기호에 따라 스토리를 전개해나가는 인터렉티브 미디어에 이르렀다. 따라서, 본 연구에서는 본 연구팀이 기존에 진행했던 연구에 이어서 이러한 인터렉티브 미디어를 지원하기 위한 전체 시스템을 설계하였고 이를 PDA 상에 구현하였다. 이 때 비디오 코덱으로는 JVT(H.264)를 사용하였으며 컨텐츠 제작을 위한 마크업 언어는 자체 정의한 IML(Interactive Media Language)를 사용하였다. 또한, 본 논문에서는 이러한 구현 과정에서 이동 단말기 들이 공통적으로 가지는 취약점인 CPU, 메모리 등의 한계를 극복하기 위한 방안도 살펴보았다.

CAPTCHA 시스템은 스팸이나 로봇에 의한 자동 가입, 계정 생성 방지도구로써 인간의 우수한 가독성을 통해 특정 언어 또는 그림을 해독할 수 있는 특성을 이용한 것으로 일반적으로 컴퓨터 프로그램이 해독하기 어려운 기호, 글자 등을 재입력하도록 하여 스팸을 위한 자동화 도구 등을 무력화 시키는 보안 기술이다. 하지만 기존에 존재하였던 텍스트 기반의 시스템은 웹봇이나 머신 러닝등을 통하여 쉽게 통과할 수 있는 단점을 나타냈다. 우리는 이러한 단점을 보완하고자 새로운 이미지 기반의 CAPTCHA 시스템을 제안하였다. 제안된 시스템은 일반적인 사진에서 부분 이미지를 출력, 무작위 회전을 가하여 사용자에게 올바른 교정을 요하는 시스템이었다. 본 논문에서는 일반적인 사진에서 출력되는 부분 이미지의 형태를 다각형으로 추출하여, 사용자에게 좀 더 인식률을 높일 수 있는 서브 이미지의 형태를 찾고, 좀 더 효과적이고 실용적일수 있는 CAPTCHA 시스템을 제안하고자 한다. 본 논문에서 제공하는 다각형의 형태는 정사각형, 정오각형, 정육각형, 정칠각형 그리고 정팔각형이다. 총 5가지 형태의 다각형 중에서 사용자에게 가장 효과적인 다각형을 실험을 통하여 찾을 것이다.

This paper proposes a system that translates the machine independent intermediate micro-programming language(IML) into microcode, using the register allocation algorithm, the microinstruction format and the field information for the target machine emulation on a microprogrammable host machine. The IML, which is for PDP-8 emulation on a microprogrammable hypothsetical 16 bit host machine, is microcoded by the proposed system, and the validity of the algorithm in the proposed system is verified by executing a test program of the target machine on the emulator.

The color combination effect is greatly influenced by individual experiences and preferences. In this paper, we will look at the associative words of color. And the combination of color and language is accompanied by a symbol of human experience. In this way, the psychological treatment effect resulting from the color combination effect is also examined.

본 연구에서는 소프트웨어의 구현 코드로부터 테스트 케이스 자동에 관해 연구하며 도구를 구현한다. 이를 통해 개발자가 직접 테스트 케이스를 작성하는 데 소요되는 비용을 절감하고, 소프트웨어의 요구사항 명세가 잘 작성되어 있지 않거나 실제 구현과 차이가 있는 경우에도 영향을 받지 않고 테스트 케이스를 생성 가능하도록 한다.

The This study aimed at clarifying that the cognitive interpretation code is essential for college students to read the correct culture while discussing the producer's story production system for creative advertising content and the process of interpreting the meaning of advertisers and the formation of principles and beliefs. The production of advertising content aimed at persuasion should first identify anachronistic reason system based on the target audience's perception principle. A concise analysis of the experiment found key clues that confirmed that a sample of the producer's intended story would be inconsistent with the clues of information that a college student could remember. I have tried to organize a semantic analysis tool that combines these key clues and as a tool for reading culture of the right time for college students. As a result, university student inmates were able to identify one side of positive communication: reading a new cognitive symbol culture based on their subjective experience and beliefs, rather than analyzing cross-sectional analysis of the primary language and non-verbal expressions of their advertising contents. In the future, if an advertising content story producer works to identify such a process in advance, it will help persuade inmates.

The Charm is composed of various kind of ancient signs, letters and systematic characters so that they delivers messages with many expressions. They, compared with the experimental typography, are more logical and experimental than we generally think. Also, they have meanings and attributes as characters do, in which there are symbols, hieroglyphs, pictures and other similar words. Each attribute diverse from symbolic meaning, associates to deconstruction of letters. It is needed to review the experimental attributes of charms with the view of structural typography for potentialities of expression. The purpose of the study is to analyze and classify the morphologic construction of charms so that we can find the possibilities of applying the attributes to visual languages and typography. Future study seems to be extending the area of expressing of typography fit for our own culture, not for Western

Hilbert's rational ambition to establish consistency in Number theory and mathematics in general was frustrated by the fact that the statement itself claiming consistency is undecidable within its formal system by $G\ddot{o}del's$ second theorem. Hilbert's optimism that a mathematician should not say "Ignorabimus" ("We don't know") in any mathematical problem also collapses, due to the presence of a undecidable statement that is neither provable nor refutable. The failure of his program receives more shock, because his system excludes any ambiguity and is based on only mechanical operations concerning signs and strings of signs. Above all, $G\ddot{o}del's$ theorem demonstrates the limits of formalization. Now, the notion of provability in the dimension of syntax comes to have priority over that of semantic truth in mathematics. In spite of his failure, the notion of algorithm(mechanical processe) made a direct contribution to the emergence of programming languages. Consequently, we believe that his program is failure, but a great one.

This study is a fundamental research for the developing 3D character contents about facial expression as a sort of non-linguistic signs, focusing on an expression of emotion factors of a person. It contributes a framework for symbolic analysis about Human's emotions along with a general review of expression. The human face is the most complex and versatile of all species. For humans, the face is a rich and versatile instrument serving many different functions. It serves as a window to display one's own motivational state. This makes one's behavior more predictable and understandable to others and improves communication. The face can be used to supplement verbal communication. A prompt facial display can reveal the speaker's attitude about the information being conveyed. Alternatively, the face can be used to complement verbal communication, such as lifting of eyebrows to lend additional emphasis to stressed word. The facial expression plays a important role under the digital visual context. This study will present a frame of facial expression categories for effective manufacture of cartoon and animation that appeal to the visual emotion of the human.

Hayao Miyazaki provides pleasure which go beyond the barrier of culture and language through realizing pan-cultural and mythical space which can communicate with the audience through unique, aesthetic expression. In his animation storytelling, diverse tangible and intangible symbolic elements based on the traditional culture inherent to Japan are actively utilized, and he provides the audience with the aesthetic pleasure of arbitrary interpretation and contemplation by composing the system of connotative signification through such symbols. In this process, he creates the value of the system of meaning which clearly conveys the mythical message of connotative meaning of the work through the aesthetic form based on the universal experience of confrontation and coexistence. It can be said that this is the communicative value of animation storytelling pursued by Hayao.
