Recently, the development of information technology (IT) continues to promote the digitalization of archives (valuable records) and has therefore, affected archiving centers. This digitalization is shown to these archiving centers by taking advantages of various digital exhibitions. This study aims to consider why it is necessary to use digital exhibitions in archiving centers. In order to examine the needs of digital exhibitions, this study focuses on some ideas and important roles in digital exhibitions and research cases of online exhibitions applied with digital technology. Consequently, this study derives some values from them. Digital exhibitions held online continuously provide the following; first, a great amount of information about the archives by using hyperlink; second, the ability to recreate the attractive contents of digitalized archives by utilizing virtual reality, which makes the users greatly interested; the third and final thing online digital exhibitions provide is the storytelling it provides, which also serves as an avenue for people to communicate with one another. These processes of communication are also reflected in the story. In addition, they can help publicize not only the archiving center, but also the local community as it promotes cultural and tourism resources.

With the upcoming Digital age, it is time to develop digitalized contents based on cultural basis. in this respect, Kimchi is one of the most primal cultural content signifying Korean culture. It's no doubt the time to initiate the movement to digitalize the contents concerning Kimchi by gathering materials on the origin of Kimchi culturally and a great value to revive digital contents regarding Kimchi. Therefore, in this research, it is regarded that Kimchi is one of the most prominent cultural value that is possible to inherit from generations and should be stratified on the database. A method explaning Korean Kimchi culture is sought in this paper. And It is focused on the culture of Korean Kimchi profoundly and focus on detailed context and varied styles of he digital contents. It is organized on the basis of various aged volumes regarding Kimchi classified by seasons, ingredients, Jonga Kimchi (Kimchi inherited from the oldest family by generations), 24 seasonal divisions of the year, and 8 regional divisions of the nation. It is planned to set up digitally-focused library regarding cultural origin of contents and to present solidity and a feeling of being dynamic The results could be used in a variety of Industries in tourism, education, Kimchi and building basic infrastructure in entertainment industry. It is also applied to specialized industry by providing cultural contents and it could contribute to activation of Kimchi industry with e-Market and portal site regarding Kimchi. Moreover, it may re-establish the cultural value of Kimchi and provide the infrastructure in Kimchi-related industry such as Kimchi cyber museum, Kimchi Expo, Kimchi town by using educational materials in Education industry fields (regular curriculum and experience tour).

Purpose: This study was to investigate visual performance and subjective satisfaction with multifocal soft contact lenses at near works in university students. Methods: In a cross-over study design, 26 students (6 male, 20 female) who did not have any ocular disorder with at least 20/20(1.0) binocular vision were fitted with singlevision lenses (SofLens$^{TM}59$, Bausch + Lomb Co. USA) or multifocal lenses (SofLens Multifocal, Bausch + Lomb Co. USA). After 2 weeks, visual performance assessments included visual acuity, stereoacuity and contrast sensitivity function at distance and near. Near point of accommodation, accommodative facility, near point of convergence, vergence facility and near range of clear vision at near were examined. Students' satisfaction and preference were measured using survey questionaries. Results: Subjects maintained at least 20/20 binocular vision with multifocal and single-vision lenses at distance and near. There was no difference between multifocal and single-vision lenses in stereoacuity, contrast sensitivity function and vergence facility at far and near. The near point of accommodation, accommodative facility, near point of convergence and the near range of clear vision with multifocal lenses were better than single-vision lenses. On the survey questionaries, subjects reported that they preferred and satisfied with multifocal lenses with near works, and single-vision lenses with distance works. Conclusions: The majority of university students preferred multifocal to single vision lenses because multifocal lenses provided better visual performance at near works. This study suggests that multifocal lens is helpful for young adult in prolonged near works.

As multimedia technologies develop, three-dimensional (3D) technologies are attracting increasing attention from researchers. In particular, video quality assessment (VQA) has become a critical issue in stereoscopic image/video processing applications. Furthermore, a human visual system (HVS) could play an important role in the measurement of stereoscopic video quality, yet existing VQA methods have done little to develop a HVS for stereoscopic video. We seek to amend this by proposing a 3D visual attention (3DVA) model which simulates the HVS for stereoscopic video by combining multiple perceptual stimuli such as depth, motion, color, intensity, and orientation contrast. We utilize this 3DVA model for pooling on significant regions of very poor video quality, and we propose no-reference (NR) stereoscopic VQA (SVQA) method. We validated the proposed SVQA method using subjective test scores from our results and those reported by others. Our approach yields high correlation with the measured mean opinion score (MOS) as well as consistent performance in asymmetric coding conditions. Additionally, the 3DVA model is used to extract information for the region-of-interest (ROI). Subjective evaluations of the extracted ROI indicate that the 3DVA-based ROI extraction outperforms the other compared extraction methods using spatial or/and temporal terms.

Recently, the development of image processing technology, as well as hardware performance, has been continuing the research on 3D point processing technology that provides users with free viewing angle and stereoscopic effect in various fields. Point cloud technology, which is a type of representation of 3D point, has attracted attention in various fields because it can acquired/expressed point precisely. However, since Hundreds of thousands, millions of point are required to represent one 3D point cloud content, there is a disadvantage that a larger amount of storage space is required than a conventional 2D content. For this reason, the MPEG (Moving Picture Experts Group), an international standardization organization, is continuing to research how to efficiently compress, store, and transmit 3D point cloud content to users. In this paper, a V-PCC bitstream generated by a V-PCC (Video-based Point Cloud Compression) encoder proposed by the MPEG-I (Immersive) group is composed of an MPU (Media Processing Unit) defined by the MMT. In addition, by extending the signaling message defined in the MMT standard, a parameter for a segmented transmission method of the 3D point cloud content by area and quality parameters considering the characteristic of the 3D point cloud content, so that the quality parameters can be selectively determined according to the user's request. Finally, in this paper, we verify the result through design/implementation of the verification platform based on the proposed technology.

This research proposes a pattern making method for women's bodice by the characters of body types and develops bodice dress forms on their body shapes applying 3D body scan data. 515 women's body scan data was collected and analyzed factor and cluster analysis. Three body types were characterized in normal, obese, and slim group. In each group, 10 subjects were selected. 20 parts in 3D anthropometric data were measured using Autocad program. The amount of waist dart was calculated and three types of basic bodice pattern were developed using the calculated darts data. The amount and the position of front dart and side dart were different at obese group in comparison of normal and thin group. The three types of basic bodice model were made by the basic bodice pattern, and each model was scanned by 3D scanner to make 3D bodice dress forms. Three types of bodice dress forms were rendered using 3D max program. Bodice dress forms had the dart lines and were useful to draft patterns to fit their body shape.

In this paper, we implemented a three dimensional image display system using stereogram and holographic optical memory techniques which can store many images and reconstruct them automatically. In this system, to store and reconstruct stereo images, incident angle of reference beam must be controlled in real time, so we used BPH(binary phase hologram) and LCD(liquid crystal display) for controlling reference beam. The reference beams are acquired by Fourier transform of BPHs which designed with SA(simulated annealing)algorithm, and the BPHs are represented on the LCD with the 0.05 seconds time interval using application software for reconstructing the stereo images. And input images are represented on the LCD without polarizer/analyzer for maintaining uniform beam intensities regardless of the brightness of input images. The input images and BPHs are edited using application software(Photoshop) with having the same recording scheduled time interval in storing. The reconstructed stereo images are acquired by capturing the output images with CCD camera at the behind of the analyzer which transforms phase information into brightness information of images. In output plane, we used a LCD shutter that is synchronized to a monitor that display alternate left and right eye images for depth perception. We demonstrated optical experiment which store and reconstruct four stereo images in BaTiO$_3$ repeatedly using the proposed holographic optical memory techniques.

Sudden increase exceeding 30million in the number of smart phone users, and rising interest in the technology of augmented reality, is now trying to combine it with AR technology in other areas very much. The field of cultural heritage, which has been constructed by the Internet and 3D technology, is not unusual and this field is now rapidly changing thanks to the AR technology which can make users experience cultural heritage with high reality. The Palaces in Seoul, however, use fragmentary tools of information - lack of heritage commentators, leaflet, etc, even though the number of visitors is gradually increasing. Therefore, three-dimensional and comprehensive cultural heritage information service is needed with the guidance in the mobile era. This study utilizes the AR technology for building the Deoksugung Tourist Information Service Application(App.) applying the markerless-based recognition technology which is a more advanced tool than the location-based AR technology. This new AR technology can switch perceived real images such as the tablet of the King in the Palace of in the real world, patterns and pedestals into virtual world, which can reproduce the damaged cultural assets as 3D. This also composes photos of the past with the current buildings, which can increase people's interest and absorption of the contents, and helps them understand and be aware of Korean traditional culture and cultural heritage effectively. In addition, convergence between IT new technology, Augmented Reality(AR) and humanities through storytelling based implementation of cultural heritage in smart phone is attempted to demonstrate that there is strength in which augmented reality technique exerts infinite creativity based on actual reality world.

The three generations of Haenam Yoon, who have been handed down to Gongjae Yoon DuSeo (1668~1715), Yoon DeokHee (1685~1776) and Yoon Yong (1708~1740), were based in Haenam. They had an artistic soul on the stage of Hanyang and succeeded in the art of the family, building a reputation as a family of Seonbi painters representing the late Joseon Dynasty. Born as the eldest son of Gongjae and lived at the age of 82, Rakseo learned a variety of studies, calligraphy and painting from his father and Lee Seo. While learning the paintings of the early and mid Joseon period, and accepting the Namjong painting method, he pursued the realism and three-dimensional sense of the subject by adding a Western-style shading method. In particular, he showed outstanding talent in horse paintings and pottery figures, expressing his original 'Beauty that realistically portrays real scenery'. Cheonggo, who was born as the second son of Rakseo and died at the age of 32, was good at Namjong landscape painting using various tree drawing methods. He painted the original Siuido by changing the topical poems, as well as detailed observations and explorations to accurately describe the facts of the object. In addition, 'Beauty showing affection through realistic scenery' was expressed by newly changing and reinterpreting the tendency of home appliances painting to express the spirit as a form beyond the realistic landscape. Rakseo and Cheonggo father and son made a 'NogUdang' painting style, drastically changing the paintings of the late Joseon Dynasty, and had a great influence on the history of Korean painting.

The characters that could be connected to diverse cultural contents have formed diverse platforms with the development of digital technology, and the size of the relevant industry and market is rapidly growing. Recently, the utilization of character emoticons for smartphone messenger has been rapidly increased, so that the characters are settled down as a tool for non-verbal communication, on top of drawing attention as an independent area. With the expansion of character market, the importance of design that could give interest and familiarity to consumers is more emphasized. The body proportion of characters includes the implicative and symbolic meanings that could express diverse personalities. Thus, this study examined the body proportion of the characters with the high consumers' preference, and then analyzed the characteristics of formative elements of character design in accordance with the body proportion. In the results of the analysis, the exaggerated form of SD characters in two or three-head figure, and the realistic Real characters in seven or eight-head figure were preferred. For the SD characters, the colors with a high chroma showing the cute and cheerful image were used. For the Real characters, the cubic effect was expressed through the colors with active images and the light and shade of color. Even though the SD characters have limited motions due to the omitted body parts, the facial movements of animation characters are exaggerated while the Real characters describe the realistic and dynamic motions.
