Video digests provide an effective way of confirming a video content rapidly due to their very compact form. By watching a digest, users can easily check whether a specific content is worth seeing in full. The impression created by the digest greatly influences the user's choice in selecting video contents. We propose a novel method of automatic digest creation that evokes a joyful impression through the created digest by exploiting smile/laughter facial expressions as emotional cues of joy from video. We assume that a digest presenting smiling/laughing faces appeals to the user since he/she is assured that the smile/laughter expression is caused by joyful events inside the video. For detecting smile/laughter faces we have developed a neural network based method for classifying facial expressions. Video segmentation is performed by automatic shot detection. For creating joyful digests, appropriate shots are automatically selected by shot ranking based on the smile/laughter detection result. We report the results of user trials conducted for assessing the visual impression with automatically created 'joyful' digests produced by our system. The results show that users tend to prefer emotional digests containing laughter faces. This result suggests that the attractiveness of automatically created video digests can be improved by extracting emotional cues of the contents through automatic facial expression analysis as proposed in this paper.

The purpose of this study was to find the space perception by the scene and to analyze the characteristics in the exhibition space. The data for the analysis was collected through a questionnaire survey method. The questionnaire is composed of a scene selection on the panoramic photographs of the exhibition space. 'The 4 Rivers Cultural Center - The ARK' was selected as the subject of this survey. The results of the study are presented as follows : First, the space perception perceived imaged scenes rather than the specific elements of space. Second, the space perception was revealed through the 'Form', 'Materials', 'Light', 'Lighting', 'Furniture' and 'Media' of notable elements. Also that was perceived by forming 'Line', 'Surface' and 'Volume'. Particularly, the perception of 'Surface' was higher than 'Line' and 'Volume'. 'Surface' was perceived mostly through the 'Color'. The perception of 'Line' was positive to 'Boundary' or 'Continuous placement of the light'. In addition, the perception of 'Volume' was positive to 'The curve of the form', 'Transparent material', 'Three-dimensional elements'. Finally, The type of space perception was chosen as 'Extension', 'Center', 'Deep', 'Boundary' and 'Formative'. In this way, the results of this study will set a foundation for developing design methods to induce the space perception by the scene in the exhibition space.

It is known that a digital image enlargement technique can increase the size of he image but the practical enhancement of resolution is trifle because the frequency bandwidth of the original image is basically limited. To solve this problem, this paper proposes the digital image enlargement technique which interpolates the interpolation points of horizontal and vertical direction by weighting according to the direction of edge information with the component of FOI(First Order Interpolation)and output of the pseudomedian filter for image enlargement and interpolates the interpolation points of diagonal direction by selectively transposing the direction of the subwindows of the pseudomedian filter according to the distribution of neighbored pixels thereto in the extended image. According to the proposed methods, the digital image enlargement which preserves the characteristic of the pseudomedian filter capable of keeping the reconstruction of edge information and reflects the advantage of FOI can be performed. Therefore, visual artifacts could be effectively suppressed, and most characteristics and shape of the original image can be reconstructed as well.

클러스터 기반 웹 시스템에서 클라이언트의 계층별 요청 형태에 따라 차별화된 서비스를 제공하려는 시도가 활발하다. 서비스 제공자와 클라이언트간의 서비스 계약 조건(SLA: Service Level Agreement)을 만족시키기 위해, 웹 스위치 단계에서 클라이언트의 서비스 요청의 내용을 파악한 후 동적으로 서버에 요청처리 작업을 할당함으로써, 클라이언트 계층별 SLA 의 제공이 가능하다. 하지만, 모든 클라이언트의 요청은 웹 스위치를 통하여 각 서버에 분배되기 때문에, 웹 스위치가 내부적 결함이나 외부의 침입에 의해 정상적인 서비스를 제공하지 못하는 경우, 웹 시스템 서비스의 다운을 초래 할 가능성이 높다. 본 논문에서는, 웹 스위치의 내부적인 결함은 물론 외부의 악의적인 공격(예, 침입, 바이러스)으로 인하여 웹 스위치에 문제가 발생하는 경우 대기하고 있는 백업(backup) 웹 스위치로 대치하여 서비스를 계속 수행함으로써, SLA 가 고려된 웹 시스템의 가용도(Availability)를 높일 수 있는 구조를 제안하였고, 마코브(Marcov) 분석 및 실험을 통해 시스템 가용도와 SLA 척도를 정량적으로 평가하였다.

The aroma pattern was analyzed using electronic nose to examine the possibility of origin discrimination according to the mixing ratio of Chinese and Korean red ginseng concentrates. The origin of Chinese red ginseng concentrate and Korea red ginseng concentrate could be distinguished and the pattern of aroma component detected decreased as the mixing ratio of Chinese red ginseng concentrate increased. Cultivar and habitat of Korean red ginseng concentrated was remarkably distinguished by the chromatogram of frequency pattern, derivative pattern and visual pattern using olfactory images known as vapor print^TM.

This paper examines the advertisements for mass-produced women's clothing, which appeared in the 1980s issues of the fashion magazine Wolganmeot. This study explores the communicative aspect of fashion advertisements of the 1980s as a platform for complex and dynamic interactions between fashion brands, female consumers, and the rapidly changing social, cultural, and economic conditions of the period. The research focuses on advertisements in the formal and character casual categories that targeted young, urban, and career-seeking women. Based on the analysis of the visual and textual elements of the advertisements from a pragmatics perspective, this paper concludes that fashion brands sought to highlight an 'intelligent', 'urban', and 'individualistic' image of women. It also proposes that the prevalence of assertive and straightforward textual elements, copies, indicates the efforts of fashion brands to stabilize and reinforce the advertising messages in the fast-evolving landscapes of the fashion industry and changing consumption habits.

There are posters of a tourist and traffics as like railroads and ships among Cassandre's posters, and they are common in dealing with 'travelling'. This series of travelling posters which includes many of his representative works, are important in the point of showing his unique styles and the process how Hey have been changed. In this thesis, I tried to analyze, especially in the plastic and graphic aspects, how Cassandre catch the peoples' desire and dreams of the travelling and images on the mechanical property of railroads and ships in 1920's and 1930's and how he put them into his works. I think that has revealed sense and visual language which has revealed through this analysis still give some messages to advertising media of moving images based on electronic technology today.

Future Ground Control Stations (GCSs) for Unmanned Aerial Vehicles (UAVs) teleoperation targets better situational awareness by providing extra motion cues to stimulate the vestibular system. This paper proposes a new virtual environment for long range Unmanned Aerial Vehicle (UAV) control via Non-Line-of-Sight (NLoS) communications, which is based on motion platforms. It generates motion cues for the teleoperator for extra sensory stimulation to enhance the guidance performance. The proposed environment employs the distributed component simulation over GSM network as a simulation platform. GSM communications are utilized as a multi-hop communication network, which is similar to global satellite communications. It considers a UAV mathematical model and wind turbulence effects to simulate a realistic UAV dynamics. Moreover, the proposed virtual environment simulates a Multiple Axis Rotating Device (MARD) as Human Machine Interface (HMI) device to provide a complete delay analysis. The demonstrated measurements cover Graphical User Interface (GUI) capabilities, NLoS GSM communications delay, MARD performance, and different software workload. The proposed virtual environment succeeded to provide visual and vestibular feedbacks for teleoperators via GSM networks. The overall system performance is acceptable relative to other Line-of-Sight (LoS) systems, which promises a good potential for future long range, medium altitude UAV teleoperation researches.

There have been many unbalanced attempts to break the rules with Renaissance movement which connects with the past in the current art. And From the latter half of Twenty century to the early half of twenty one century, the common sense of fashion is turned over by(unthinkable fashion). To analyze current apparence of fashion, this research make a comparison of fashion condition between the sixteenth century and twenty century fashion, Three analysis methods is introduced. First of all, this paper make research of original language of mannerism and unthinkable apparence. Second, appearances of mannerism fashion and unthinkable fashion which are taken from reference books and pictures. Third, Gathering methods which express own style between two periods in the end part of research. As a result, Although Mannerism isn't practical for the visual and new pleasure, and neglect humanism of Renaissance, It is a tendency which is willing to change the flow of prevailing mode, and to reflect asking of people each periods. Mannerism and unthinkable fashion is apparence of society to refresh own feeling. And then, Mannerism and unthinkable fashion is a new challenge to escape from fixed thought.
