멀티미디어 인터페이스와 관련된 제반 요소들 가운데 사용자, 사용자와 컴퓨터 시스템간에 교환되는 내용이나 지식, 그리고 양자를 연결하는 매체가 주요 축이 되고 이들간의 접점에서 디자인 해결을 요구하는 문제들이 발생한다. 이중 사용자는 가장 중요한 디자인 영향요소인데 멀티미디어의 다중양식의 특성에서 볼 때 인지적 특성에 대한 고려가 중요하다고 보고 이를 디자인 평가의 주요 원리로 삼았다. 매체는 정보전달의 전체 과정 중에서 다양한 수준의 개념으로 해석될 수 있으므로 이에 대한 체계적 구분을 바탕으로 하여 다양한 매체들의 정보 전달 시 나타나는 특징, 표현방법들을 파악할 필요가 있다. 이의 체계적 분석은 평가 및 디자인 개발의 주요한 대상이 된다. 본 연구에서는 멀티미디어 인터페이스를 내용, 매체, 표현요소의 복합체로 보고 이의 체계화된 하부요소들을 파악하여 일련의 디자인 원리에 부합되는지를 평가하는 프로세스를 체계화하였다. 이를 통해 인터페이스 디자인의 특징과 정보 전달 효과간의 관계를 밝힐 수 있을 것으로 보고, 이를 디자인 개발과 연계시킴으로써 멀티미디어 인터페이스 디자인의 통합적 시스템으로 발전시켜야 할 것이다.

The Inter-Channel Level Difference (ICLD) is a cue parameter to estimate spectral information in a binaural cue coding that has been recently in the spotlight as a multichannel audio signal compression technique. Even though the ICLD is an essential parameter, it is generally distorted by quantization. In this paper, a new modified ICLE representation method to minimize the quantization distortion is proposed by adopting a flexible determination of the reference channel and the unidirectional quantization. Our experimental result confirms that the proposed method improves the multichannel audio output quality even with the reduced bit-rate.

객체지향 설계에 많이 사용되고 있는 UML의 일부 다이아그램들의 일관성과 완전성을 검증하기 위하여 UML다이아그램들을 분석하여 ER모델에 적용하고, 일련의 집합과 함수들을 사용하여 정형적으로 명세한 다음 이러한 함수들의 의미에 따라 UML 다이아그램들의 일관성과 완전성을 보장하는 일련의 규칙들을 유도한다. 이러한 규칙들은 추후에 다이아그램을 생성하는 능력과 일관성과 완전성을 검사하는 능력을 함에 가진 CASE 도구에 포함될 수 있다.

All kinds of artwork, including multimedia and digital image that has been subliminated into an af mediating two numbers 0 and 1 in recent age, are self-sufficient and autonomous in themselves. Nevertheless, each of those artworks can be realized as a real entity only if its appreciator is capable enough to explore some potential meaning out of it through his or her own perceptual work. According to Mikel Dufrenne, an artwork is composed of three existential tiers: "le sensible" or the sensible material; "fe representation" or the subject(le sujet), and "1′expression." Dufrenne contends that our esthetic perception can be realized by way of three steps that are comparable to those three tiers: perception of the presence of the body("le sensible"), contemplative perception by way of imagination("le representation"), and reflective perception ("1′expression") as a result of dialectics of sense and sensibility. This paper argues on the aesthetic perception with regard to digital image expressed by two numbers 0 and 1, putting focus on the epistemological role of sensibility(감) that explores "1′expression" a la Dufrenne.

Chinese is the most spoken language in the world. However, because Chinese is a hieroglyphic language, using Chinese in a digital environment is very inconvenient. Chinese users are using Pinyin for Chinese input, but the phonetic representation of the Latin alphabet is not good. Hunminjeongeum has an excellent phonetic representation which can improve Chinese usage in digital environment. Therefore, it is possible to improve the use of Chinese by Chinese users in digital environment and to help Korean users who are learning Chinese. Therefore, this paper proposes a Chinese input method using Hunminjeongeum. In addition, we develop an input software using this input method and verify its effectiveness by evaluating usability.

This article analyzes the background representation of 3D animation and look at what its proper background expression. With the development of computer graphics technology, the background of the 3D animations can be expressed as The actual background. In contrast, "The Smurfs" which was released recently was created to take the actual background. However, 3D animation with real background is not appropriate in terms of creative expression space in the main role of the animation. In this Study, we analyze the character and background of the animation made in 3D graphics. Based on this, we propose a correct representation of 3D animation background.

스토리에 의해서 콘텐츠 산업의 경쟁력이 결정되고 콘텐츠에 대한 흥행과 보급에 핵심 요소가 된다. 현재까지의 스토리에 대한 연구는 대부분 인문학의 분야에서 이루어지고 있다. 인문학에서는 스토리를 창작하는 방법과 스토리에 대한 해석에 주로 초점이 맞추어져서 연구가 이루어지고 있다. 콘텐츠 산업의 핵심요소인 스토리를 창작하거나 해석하기 위해서는 스토리를 한눈에 보고 이해하거나 설명하기 위한 다양한 해석 방법과 시각화 방법이 필요하다. 따라서 본 논문에서는 스토리의 무대가 되는 공간 정보와 인물 정보가 함게 고려된 장면 그래프에 대한 연구를 제시하고 설명한다.

The extraction and recognition of human motion characteristics need to combine biometrics to determine and judge human behavior in the movement and distinguish individual identities. The so-called biometric technology, the specific operation is the use of the body's inherent biological characteristics of individual identity authentication, the most noteworthy feature is the invariance and uniqueness. In the past, the behavior recognition technology based on the single characteristic was too restrictive, in this paper, we proposed a mixed feature which combined global silhouette feature and local optical flow feature, and this combined representation was used for human action recognition. And we will use the KTH database to train and test the recognition system. Experiments have been very desirable results.

Melanoma is a skin cancer that starts in pigment-producing cells (melanocytes). The death rates of skin cancer like melanoma can be reduced by early detection and diagnosis of diseases. It is common for doctors to spend a lot of time trying to distinguish between skin lesions and healthy cells because of their striking similarities. The detection of melanoma lesions can be made easier for doctors with the help of an automated classification system that uses deep learning. This study presents a new approach for melanoma classification based on an ensemble of deep convolution neural networks and a Log-Gabor filter. First, we create the Log-Gabor representation of the original image. Then, we input the Log-Gabor representation into a new ensemble of deep convolution neural networks. We evaluated the proposed method on the melanoma dataset collected at Yonsei University and Dongsan Clinic. Based on our numerical results, the proposed framework achieves more accuracy than other approaches.

Currently in the Web(World Wide Web) environment, HTML(Hyper Text Markup Language) is used for information representation and exchange. But it is thought that HTML has some constraints in information representation of various kinds because of its limited tag set. And it is considered that combining the HTML, which is used for static information representation in Web environment, with Scripting language, which is usually used for multimedia information representation in a synchronized framework, can be very useful. Consequently we show the general trend of the Scripting language in Web environment and show the possibility of HTML and Scripting language amalgamation for Web service improvement.
