The existent UCC sites display only finalized contents by publisher. It dose not provide any platform for resources of UCC that public users could reorganize. This paper has developed a platform to be able to produce reusable content using the scenes of the contents and produced a 3D animation with multiple story. It is necessary for user to search the provided contents for easy reorganization of the contents. The scene is classified by the description and information of the scene for handy search. It is obscure for a movie clip to be represent with only one word. Therefore, the proposed platform provides the search technique with a overlapping choice for the specific categories that include most of elements for the scene. Then the user can choose a specific range of the selected movie clip, make a new story with reorganizing the order, and put a caption or BGM on the movie clip. The complete movie clip has the search preferences as a category, new clips, and top favorites. With the Multi-Story line concept, we made a 3D animation about episodes of thermal dolls in the Doll World. This attempt will come to the new marketing way for a field of the visual media like as Music Video, Drama, Feature Film, Commercial Film.

In this study, external representation presented in two units, 'Property of Gas' and 'Changes of States of Matter,' in seventh grade of 2015 revised science curriculum, were analyzed to suggest educational implications. External representations presented in five science textbooks were analyzed according to the six criteria, which were 'type of representation,' 'interpretation of surface features,' 'relatedness to text,' 'existence and properties of a caption,' 'degree of correlation between representations comprising a multiple one,' and 'function of representation.' The characteristics of typical representations related to each achievement standard of two units were also analyzed. The results were as follows: The macro representations for 'type of representation', and explicit representations for 'interpretation of surface features' showed highest frequency. For 'relatedness to text' criteria, 'completely related and linked' and 'completely related and unlinked' representations showed the highest frequency. It means that most representations were properly related with the text. There were appropriate captions for most representations. The degree of correlation between representations comprising a multiple one was largely sufficiently linked with regards to the criteria 'degree of correlation between representations comprising a multiple one'. The complete representations for 'function of representation' showed the highest frequency in the aggregate, however incomplete representations showed more frequencies in the inquiry parts. The typical representations for each achievement standard differed in terms of the type, contained information, used symbols and so on. The educational implications with the use of representations presented in seventh grade textbook were discussed.

The carelessly and illegally copied contents are raising serious social problem as internet and multimedia technologies are advancing. Therefore, development of video copy detection system must be settled without delay. In this paper, we propose the hierarchical video copy detection method that estimates similarity using statistical characteristics between original video and manipulated(transformed) copy video. We rank according to luminance value of video to be robust to spacial transformation, and choose similar videos categorized as candidate segments in huge amount of database to reduce processing time and complexity. The copy videos generally insert black area in the edge of the image, so we remove rig black area and decide copy or not by using statistical characteristics of original video and copied video with center part of frame that contains important information of video. Experiment results show that the proposed method has similar keyframe accuracy to reference method, but we use less memory to save feature information than reference's, because the number of keyframes is less 61% than that of reference's. Also, the proposed method detects if the video is copied or not efficiently despite expansive spatial transformations such as blurring, contrast change, zoom in, zoom out, aspect ratio change, and caption insertion.

Recently, with the development of computing technology and the improvement of the cloud environment, deep learning technology has developed, and attempts to apply deep learning to various fields are increasing. A typical example is anomaly detection, which is a technique for identifying values or patterns that deviate from normal data. Among the representative types of anomaly detection, it is very difficult to detect a contextual anomaly that requires understanding of the overall situation. In general, detection of anomalies in image data is performed using a pre-trained model trained on large data. However, since this pre-trained model was created by focusing on object classification of images, there is a limit to be applied to anomaly detection that needs to understand complex situations created by various objects. Therefore, in this study, we newly propose a two-step pre-trained model for detecting abnormal situation. Our methodology performs additional learning from image captioning to understand not only mere objects but also the complicated situation created by them. Specifically, the proposed methodology transfers knowledge of the pre-trained model that has learned object classification with ImageNet data to the image captioning model, and uses the caption that describes the situation represented by the image. Afterwards, the weight obtained by learning the situational characteristics through images and captions is extracted and fine-tuning is performed to generate an anomaly detection model. To evaluate the performance of the proposed methodology, an anomaly detection experiment was performed on 400 situational images and the experimental results showed that the proposed methodology was superior in terms of anomaly detection accuracy and F1-score compared to the existing traditional pre-trained model.

Broadcasting programs are provided to various media such as Internet replay, OTT, and IPTV services as well as self-broadcasting. In this case, it is very important to provide keywords for search that represent the characteristics of the content well. Broadcasters mainly use the method of manually entering key keywords in the production process and the archive process. This method is insufficient in terms of quantity to secure core metadata, and also reveals limitations in recommending and using content in other media services. This study supports securing a large number of metadata by utilizing closed caption data pre-archived through the DTV closed captioning server developed in EBS. First, core metadata was automatically extracted by applying Google's natural language AI technology. The next step is to propose a method of finding core metadata by reflecting priorities and content characteristics as core research contents. As a technology to obtain differentiated metadata weights, the importance was classified by applying the TF-IDF calculation method. Successful weight data were obtained as a result of the experiment. The string metadata obtained by this study, when combined with future string similarity measurement studies, becomes the basis for securing sophisticated content recommendation metadata from content services provided to other media.

$\^$137/Cs gamma ray induced thermoluminescenc(TL) from Na$\^$+/ ion implanted Al$_2$O$_3$ and unimplanted Al$_2$O$_3$ and the TL from Na$\^$+/ ion implanted Al$_2$O$_3$ are measured over the temperature range of 340K～620K. The TL curve of Na$\^$+/ ion implanted Al$_2$O$_3$ induced by $\^$137/Cs gamma ray is split into iolated TL peak located at 415K, 452K, 508K, and 568K. Because that the concentration of trapped char he carries of $\^$137/Cs gamma ray induced Al$_2$O$_3$ implanted with Na$\^$+/ ion is larger than that of Na$\^$+/ ion only implanted Al$_2$O$_3$, and the trap concentration of Na$\^$+/ ion implanted Al$_2$O$_3$ is much than that of $\^$137/Cs gamma ray only irradiated Al$_2$O$_3$, the TL intensity of Na$\^$+/ ion implanted Al$_2$O$_3$ induced by $\^$137/Cs gamma ray is about 20 times and 5 times higher than that of Al$_2$O$_3$ only implanted with Na$\^$+/ ion and Al$_2$O$_3$ only irradiated with $\^$137/Cs gamma ray, respectively. In proportion as ion implantation does and energy are incresed, the number of generated defects and the rate of defect creation are incresed, respectively. Therefore the TL intensity of ion implanted Al$_2$O$_3$ is depend on ion dose and energy. Acccrding to increse of incident ion mass, the TL intensity of ion implanted Al$_2$O$_3$ is abruptly decresce. This result showes that the TL intensity of ion implanted Al$_2$O$_3$ is closely related to ion depth range as wll as rate of defect creatin. The TL intensity of ion implanted Al$_2$O$_3$ is found to be related with defects generated by ion implantation. Table Caption

This study is aiming to acquire data for enhancing genuineness of restoration through reviewing external and internal scenery of Baegun-dong Wonlim such as Baegun-dong 8 Objects of Scenery(pines, bamboos, chrysanthemum, orchid, maehwa blossom, magnolia, fiddle and crane) and 12 Scenic Spots and reviewing internal and external scenery of Baegun-dong Wonlim such as views and scenery for plantation. For Baegun-dong 8 Young which sang songs about scenic spots of Baegun-dong Wonlim it seemed that its head words were formed through borrowing rhyming words from caption of Baegun-dong Yuseogi(白雲洞幽棲記). Accordingly it seemed these scenery secured its status of Wonlim from the beginning. Particularly the words of fiddle and crane in 琴棋書畵(Geumgisuhha) implied that playing Komungo and brushwriting were firmly rooted as romantic pursuits of classical scholars of that time. In consideration of distance upto Okpanbong which is one of 12 scenic spots of Baegun-dong radius of outer circumference is estimated to be around 1.6km. From Okgpanbong, the epicenter, Sandagyeong, Baegokmae, Hongokpok and Pungdan etc. correspond to transitional space. And inner scenery was formed with hub of thatched cottages and bowers surrounded with chrysanthemums, poenies, rhododendron, Phyllostachys bambusoides, pines and upper and lower water paths. Thus it seemed there was scenic structure of centrifugal nature as well as of multiplicity. Forms of majority of water paths with residual structure found in the country have streamlined forms on the other hand Baegun-dong water paths have straight line which almost dominate inner gardens in terms of scale and forms thus revealing its extraordinary idea and design. In order to promote genuine restoration of Baegun-dong Wonlim it will be necessary to have consideration from standpoint of managing perspective to assure presentation of gradual scenery with elements of scenic objects for outer view among 12 Scenic Spots.

Barrier-free films enhance accessibility to audiovisual image contents by providing specific information on screen and through sound so that people with vision or hearing loss can receive the same amount of information as those without disabilities and immerse themselves in the audiovisual images. This study pays attention to barrier-free audiovisual contents in relation to the cultural civil rights of people with vision or hearing loss in South Korea. While institutional efforts have been made in the 2010s to improve the access to audiovisual media of people with vision or hearing loss, the goal of enabling people with vision or hearing loss to fully enjoy all audiovisual contents at a level equal to the non-disabled has not yet been realized. Amid the lingering conflict between disabled groups and multiplexes that has lasted years, the global video streaming service Netflix has aggressively threatened the dominance of local multiplexes with the launch of its Korean service. As Netflix, which is subject to U.S. regulations guaranteeing the rights of people with vision or hearing loss, has produced original dramas and movies involving Korean production teams, the cultural civil rights discourse of the disabled has transitioned to the issue of the rights of cultural consumers crossing national borders in the era of globalization. Changes in the media environment raise the issue of civil rights guarantees in which disabled people enjoy the right to simultaneously watch movies and comment on movies by participating in a common discourse, equally with non-disabled people. The "right to be part of the audience for Korean cinema" for Korean deaf people, which has long been neglected, should also be considered as a cultural civil right that crosses the boundaries of language, nation and disabilities. This essay examines the current issues surrounding the right to cultural entertainment of people with vision or hearing loss in South Korea in conjunction with the contemporary trend of rapid changes in the media environment and the global spread of the movement for cultural civil rights of people with disabilities, and suggests the need for visual culture studies to take a serious step toward disability studies.
