Recently, most of movies top-ranked in the box office are screening in Stereoscopic 3D, and the world's leading electronics companies such as Samsung and LG are getting the hots for 3DTV sales. However, each person has different binocular disparity and different viewing distance, and thus he or she feels the severe visual fatigue and headaches if he or she is watching 3D content with the same binocular disparity, which is very different from things he or she feels in the real world. To solve this problem, this paper proposes and implement a 3D rendering system that correct the disparity of 3D content by reflecting binocular distance and viewing distance. Then, the computational complexity is analyzed. Optical-flow and Warping algorithms turn out to consume 732 seconds and 5.7 seconds per frame, respectively. Therefore, a dedicated chip-set for both blocks is strongly required for real-time HD 3D display.

최근 세계적으로 한국에 대한 인식이 좋아짐으로써 한국으로 유학이나 여행을 오는 외국인이 많아지고 있다. 외국은 다양한 문화와 언어를 가지고 있고 그 외국의 문화와 언어에 익숙하지 않은 많은 식당에서 그들은 식사함에 어려움을 겪고 있다. 우리 학교의 경우에서도 마찬가지로 유학 와 있는 한국어가 서툰 학생들이 한국에서 가장 불편한 일 중 하나가 식당에서 음식을 시키는 것이라고 할 정도로 식사가 제한되어 있다. 이를 해결하기 위해 본 논문에서는 QR 코드를 메뉴판에 부착하여 그 QR 코드를 찍기만 하면 바로 원하는 언어를 선택할 수 있고, 그들의 언어로 음식에 대한 설명이 나타나는 시스템을 제안하고 개발하였다. 제안한 시스템은 종교에 따라 먹지 못하거나, 식습관에 따라 먹지 않는 음식이 있는 외국인들 역시 전자 메뉴판을 이용함으로 어려움을 해결 할 수 있다. 제안한 시스템은 그들 주변에 어떤 식당이 있고 어떤 음식이 있는지 쉽게 알 수 있고 그 어플을 사용하는 사람들과 소통할 수 있는 어플리케이션을 제작함으로써 유학생뿐만 아닌 일반 관광객들을 대상으로도 적극적으로 활용 할 수 있을 것으로 기대가 된다.

Hallyu pop-culture contents which has influenced the world has sufficient preservation value as a cultural asset. However, there is still a lack of awareness of long-term preservation of Hallyu pop-culture contents and digital archiving is not in full swing, too. We requires accurate understanding of the concept, characteristics, format, media, and relationship of contents for digital archiving of Hallyu pop-culture content. Thus, this study analyzed and organized the concept, characteristics, and preservation subject of Hallyu pop-culture contents, as basic study for digital archiving of Hallyu pop-culture contents. In addition, we investigated the current status of digital archives (systems/institutions) of Hallyu pop-culture contents and Hallyu pop-culture contents, and presented basic proposal based on the problem factors.

In this paper, we describe the Solar Car, Woongbi, which was created to participate in the World Solar Challenge(WSC) at the team NeulHaeRang of Korea National University of Transportation. The WSC is the world's largest solar car racing competition and has a separate automobile regulation and must be manufactured to meet the regulations. Therefore, the key point of the solar car design is to optimize the energy efficiency based on the regulations. The solar car's drive system consists of a solar array to convert solar energy into electric energy, a maximum power point tracker (MPPT) controller to track the converted electric energy to maximum output power, a battery to store the produced electric energy, a BLDC (Brushless DC) motor for driving the vehicle by converting energy into mechanical energy, and a motor controller for controlling the BLDC. The optimal design methods for solar energy conversion and electric driving system of battery, motor are presented in this paper.

Ecomuseum which appeared in France in 1968 and widely diffused over the world, is a new type of museum. The purpose of this museum is not to simply possess and exhibit the existing relics, but to discover the locational senses of a territory by in-situ conserving and interpreting its entire natural and cultural heritages, and to plan the participation of its population and the development of its local community. The significance of this museum can be found in the recovery of disappearing collective memories of a territory, the restoration of the cultural identity of its population and the revitalization of a underdeveloped area. As the majority of these museums are fragmented or open air museums, an 'web ecomuseum' which makes the remote offering of informations about whole dispersed heritages and their holistic interpretation possible by digitalizing, recording, conserving, interpreting and utilizing related heritages, is necessary. This paper considers the possibility of web ecomuseum and its constitution contents and methods through the case of Mountain Mudeung area. Especially, in relation to the latter, this paper suggests a plan which consists of selection of own local themes, construction of digital archives, design of web expositions and production of electronic cultural maps.

Recently realistic descriptions have been frequently used in anti-smoking campaigns. The same trend can also be seen with regard to posters as a medium of visual communication. It was intended to examine how different types of visual images in anti-smoking campaign posters produced and distributed by the WHO can improve the effectiveness of health communication. This article aims to determine how each of abstract/stylized illustrations and realistic images might affect the three key variables of the Theory of Planned Behavior, which are Attitudes toward the Behavior, Subjective Norms and Perceived Behavioral Control, in relation to quitting smoking. Results showed that realistic images are different in improving the attitudes toward the behavior and subjective norms. However, there are no significant difference between abstract/stylized illustrations and realistic images in Perceived Behavioral Control. The findings of this study suggest that the above-mentioned types of visual information achieve different levels of effectiveness in health communication. It is desirable that more effort be devoted to the interdisciplinary study across the areas of visual design and social psychology, for example, with a view to developing better health communication strategies.

Owing to the present problems of air pollution and fossil fuel exhaustion, ongoing research has been actively focused on developing an electric actuator system that can utilize diverse energy sources without producing any exhaust gas. Since the motors of such electric vehicles generally rotate at a high speed, the initial acceleration capability required for an automobile is insufficient. In this study, the motor output was decelerated by the transmission; the initial acceleration of the vehicle was increased, and the motor size and weight were reduced. The driving motor and transmission, which each form isolated structures, were integrated to simplify the connector for input and output. By reducing the cooling system's capacity, a vehicle was designed and manufactured that represents a structural change in effective technology.

The characters' voices in the movie, Rashomon mean the absence of memories created by self-consciousness in order to avoid the crisis. The varying statements of the characters and the three spaces: the space of Nakanimon (th e ruins), the representation space as polyphony (the forest), the egoistic space of truth (the guardian), show the social ills of doubtfulness and mistrust among the Japanese at that time due to the defeat from the war. This matches with the polyphony theory of Mr. Bakhtin, a Russian cultural critic. The key concept of polyphony theory is that the voices that do not accord each other are not harmonized but each voice builds their own world and participates in the novel without being influenced by the creator. This study's aim is to discuss two aspects; Bakhtin's polypony theory allows polyphony film s to function as cinematic composition and spatial characteristics of polyphony films in the movie, Rashomon.
