The purpose of this study is to analyze the characteristics of the urban landscape by CG(Computer Graphic) pictures and visibility analysis. In this study, the CG picture was created by using zoning data and DEM(Digital Elevation Model) on Chunchon city. The landscape type was classified into three by cluster analysis using the area rate of the element which constitutes CG picture. Visible analysis used DEM as fundamental data, and was performed by using GIS(Geographic Information System). And the frequency seen on viewshed was classified into five grades. The result of this study are as follows: 1. The area rate of the element which constitutes CG picture was high development restriction zone(43%) in type 1, green land area(39%) in type 2, and city area(24%) in type 3. 2. In the analysis results of GIS visibility analysis, it turns out that Euiam lake is important area on the landscape in all types. 3. The land use of high frequency seen on viewshed was water area, residential area in type 1, development restriction area, park area in type 2, and development restriction zone, water area in type 3.

Digital technology has advanced rapidly and it is anticipated that multimodal ways of meaning-making will become increasingly important. Consequently, teaching multimodal literacies is becoming a major issue in education. This study focuses on the use of picture diaries as a means of teaching multimodal literacies. Picture diaries are one of the basic and unique multimodal texts used in lower elementary level classes in Korea. A further advantage is that it is a promising text model which can be taught in unplugged ways. In order to explore the educational implications of using such picture diaries, this study sought to analyze the ways in which twenty four $1_{st}$ graders in an elementary school constructed meaning with written language and pictures in composing picture diaries. 251 picture diaries composed during several months of their $1_{st}$ grade period were analyzed based on the constant comparative method. The results indicated that the students utilized both written language and pictures in diverse and creative ways to provide their audience with more comprehensive meaning. These results indicate that teachers need to consider their students as active multimodal meaning-makers and provide their students with more opportunities to practice multimodal meaning-making and share their experiences.

Most of digital media contents are composed with video and audio, picture and animation informations. Sometime, there is some deviation of information recognition quality for the video and audio information according to information receiver's characteristics or the understanding. But visual information using the text provide most clear and accurate ways for information recognition to human being. In this paper, we propose a new broadcasting system(BSDMC) to transmit clear and accurate meaning of the digital media contents. We implement general-purpose components to display the video, picture, text and symbol simultaneously. Only plug-in and call these components with proper parameters on the application developing tool, we can easily develop the multimedia contents broadcasting system. These components are implemented based on the object-oriented framework and modular structure so that increase the reusability and can be develop other applications quick and reliable.

본 연구의 목적은 교수매체로써 그림책을 탐색하고자 하는 초등학교 교사들의 접근점에 대한 요구를 파악하고 학교도서관 DLS(Digital Library System)의 접근점 개선방안을 제안하는 것이다. 이를 위해 먼저 국내외 7개 도서관 온라인목록시스템에서 제공하는 접근점을 조사하였다. 그리고 초등학교 교사들을 대상으로 온라인 설문조사를 실시하여 최종적으로 220개의 응답을 분석하였다. 분석 결과, 교사들이 가장 필요로 하는 그림책의 접근점은 주제, 학년/연령, 내용, 교과/단원, 범교과학습주제 등으로 나타났다. 이러한 결과를 바탕으로 본 연구는 필요성이 높게 나타난 접근점을 DLS의 목록레코드에서 제공하고, 통제어휘집을 개발하고, 시스템의 기능이나 인터페이스를 개선하여 그림책에 대한 접근성을 향상시키는 방안을 제안하였다.

In this paper we propose a haptic interaction system that physically represents the underlying geometry of objects displayed in a 2D picture, i.e., a digital image. To obtain the object's geometry displayed in the picture, we estimate the physical transformation between the object plane and the image plane based on homographic information. We then calculate the rotated surface normal vector of the object's face and place it on the corresponding part in the 2D image. The purpose of this setup is to create a force that can be rendered along with the image without distorting the visual information. We evaluated the proposed haptic rendering system using a set of pictures of objects with different orientations. The experimental results show that the participants reliably identified the geometric configuration by touching the object in the picture. We conclude this paper with a set of applications.

Smooth picture module is operated by vibration to tilt the light from the DMD (digital micro mirror device) of DLP projection TV, which makes the screen of the TV smoother and DMD chip cost lower. To satisfy the vibration characteristics of smooth picture module, it is designed by optimizing moment of inertia, spring constant and damping coefficient, using structural and fluid dynamic simulation that showed a good agreement with experimental data. To reduce the material cost and moment of inertia, engineering plastic is used and the reliability is estimated. A VCM (voice coil motor) type actuator for smooth picture has to satisfy performance requirements such as higher driving force, lower power consumption, and lower cost. The initial design and optimization for VCM was performed using FE analysis. It allowed us to optimize the design of magnetic circuit of the proposed actuator to obtain higher force while maintaining a lower cost.

Automatic pattern recognition using computers has manu potential applications. In many cases successful automatic pattern recognition procedures require an analysis of texture of a picture by a conventional digital computer: but this involves a type af computing that is at the present time extremely time-consuming and thus very expensive. In response to this situation, TEXAC was designed and built which is capable of most whole picture operations at a rapid television rate of 1/30th of a second. The results of operations are displayed continuously on color and black-and-white television monitors. The paper presents the architecture of the TEXAC, the picture processing language developed and some of the results of TEXAC whole picture operations.

한국 영화는 개화기에 도입된 이후 현재 세계적으로 호평 받는 수준으로 발전하였으며 산업적으로도 큰 성장을 이루었다. 그러나 최근 디지털시네마 및 입체영화의 등장 등 급진적 기술이 등장함에 따라 해외 기술의 도입 위주로 진행되던 기술 전략 정책에 변화가 요구되고 있다. 이에 본 논문은 영화산업의 기술혁신에 초점을 두고 한국 영화산업의 기술혁신체제를 분석한다. 영화산업 관련 기존 문헌 분석과 전문가 인터뷰를 통해 한국 영화산업의 기술 및 지식, 제도, 혁신주체와 네트워크를 조망해 보며, 이를 통해 한국 영화산업 기술학신체제의 특정과 문제점을 규명하는 것이 본 논문의 목적이다. 연구결과 영화산업 기술혁신의 한국적 특정을 규명하였으며, 지식 축적 과정의 단절, 영화산업 특수적 연구개발 활동의 부재, 혁신주체의 전문성 결여 등과 같은 문제점도 도출할 수 있었다. 이를 바탕으로 본 논문에서는 영화산업 기술혁신을 위한 정책적 함의를 제공한다. 또한 본 논문은 기술혁신연구 분야에 영화산업을 소개함으로써 새로운 연구 기회를 제공한다는 의의도 갖는다.

온라인 게임에서 동영상은 게임을 홍보하는 중요한 수단이며, 게임 진행에 많은 도움을 준다. 이 경우에 동영상은 저장 공간의 효율적인 사용과 네트워크 자원의 효율성을 위해 가변 비트율 형태로 압축된다. 적응형 대역폭 할당은 게임 동영상에 대한 전송 계획을 세우고 이 계획에 의한 전송률이 가용 전송률보다 큰 경우에 가용 전송률을 만족시킬 때까지 일부 프레임을 폐기시켜서 전송하는 방법이다. 이때, 적응형 대역폭 할당 방법에서의 평가 요소들은 전송률을 설정하는데 크게 영향을 준 프레임들의 폐기 순서에 따라 크게 달라질 수 있다. 본 논문에서는 이를 살펴보기 위하여 전송 계획에 사용되는 CBA, MCBA, MVBA, [6]], [7]의 알고리즘들을 적응형 대역폭 할당 방법의 전송 계획으로 각각 적용하여 다양한 프레임 폐기 방법들로 성능을 평가한다.
