Machine translation refers to software that translates a source language into a target language, and has been actively researching Neural Machine Translation through rule-based and statistical-based machine translation. One of the important factors in the Neural Machine Translation is to extract high quality parallel corpus, which has not been easy to find high quality parallel corpus of Korean language pairs. Recently, the AI HUB of the National Information Society Agency(NIA) unveiled a high-quality 1.6 million sentences Korean-English parallel corpus. This paper attempts to verify the quality of each data through performance comparison with the data published by AI Hub and OpenSubtitles, the most popular Korean-English parallel corpus. As test data, objectivity was secured by using test set published by IWSLT, official test set for Korean-English machine translation. Experimental results show better performance than the existing papers tested with the same test set, and this shows the importance of high quality data.

One notable challenge in video searching and summarizing is extracting semantic from video contents and annotating context for video contents. Video semantic or context could be obtained by two methods to extract objects and contexts between objects from video. However, the method that use just to extracts objects do not express enough semantic for shot or scene as it does not describe relation and interaction between objects. To be more effective, after extracting some objects, context like relation and interaction between objects needs to be extracted from conversation situation. This paper is a study for how to detect speaker and how to compose context for talking to annotate conversation context. For this, based on this study, we proposed the methods that characters are recognized through face recognition technology, speaker is detected through mouth motion, conversation context is extracted using the rule that is composed of speaker existing, the number of characters and subtitles existing and, finally, scene context is changed to xml file and saved.

This research paper aims to inform and suggest methods in which Korea Media content could successfully enter the African broadcasting market. It also seeks to suggest preparatory steps and propose various policies that Korean government could provide, to aid the export process. In order to maximize the Korean media content exposure in the Kenyan market, increased financial support for subtitles and dubbing as well as launching a Korean culture center is suggested. In addition, to encourage more diverse channels to show the Korean content, joint content production between Korea and Kenya should be considered. Moreover, in analyzing the social, cultural, ethnic and local characteristics of the Kenyan people, the paper seeks to identify the most efficient method in which Korean wave could be more widespread in Kenya. Since virtually no prior research papers exist on Kenyan's social and cultural characteristics and their thought process on the Korean media content, this paper seeks to provide valuable insight and policy implications for Korean media policy makers.

Reportage documentary by SBS did a great role to keep public sphere whether other programs shrinked during 2010's. I analysed with the assumption that there are some rhetorical characteristics in narrative structure of . Looking as 'Mysterious reportage documentary' I analysed the rhetorical characteristics of title, subtitle and script. Title has a perspective to suffice audience's desire and subtitles uses word 'mystery', names of place, interrogative sentences very often. This use helps to draw and keep audience's attention. I found reversal of fortune rhetoric, into depth rhetoric and admiration rhetoric salient. These results connect to the design thinking approach which shed light on importance of person, and we could get an implication of the successful development of television contents.

Objectives : I'd like to introduce a Korean medical scientist, Lee Gyoojoon (李圭晙, 1855-1923)'s achievements about Huangdi's Internal Classic (黃帝內經, HIC) to examine the Section of Viscera and Bowels to inspect the Medical Classics (稽經藏府篇, SVBIM) of the Double grinded Medical Mirror (醫鑑重磨, DMM), which is a medical book published in 1922, his last studies. And I'd like to describe its meaning of medical history. Methods : For this, I compared the DMM with two primary texts, the representative medical books of Joseon dynasty, Treasured Mirror of Eastern Medicine (東醫寶鑑, TMEM) and Lee's former research result of HIC, Major Essentials of Huangdi's Internal Classic Plain Question (黃帝內經素問大要, MEHIC), in the aspects of the original text, annotation, editing, attached theses, and so on. Results : Lee Gyoojoon criticized the TMEM in two aspects. First, it was unfocused and miscellaneous, second, it intended to help Yin Qi (陰氣) and reduce Yang Qi (陽氣) so that it regards a prime mover, Yang Qi, as an enemy. In order to solve these problems he deleted miscellaneous articles and sort out the points to accord with the HIC. As a result, he had written the Section of SVBIM of the DMM in the form of revising the subtitles or refuting the contents of TMEM and quoted the partial texts of MEHIC to be written by the view of Supporting Yang Qi (扶陽). Conclusions : Lee Gyoojoon proposed the Supporting Yang Qi medicine to preserve the Heart fire (心火) based on his lifelong Neo-Confucianism (性理學) study. The Section of SVBIM of the DMM showed how to apply his medical theory, which is achieved by the study of the medical classic HIC to real clinical medicine through a medium of the TMEM. In addition, it could explain concretely how the Confucianists studied the medicine and how Confucianism can impact to the development of medical theory.

This study investigated the effects of an Augmented Reality(AR) implemented book on flow of reading, interest in history, and acquisition of history knowledge. Perceptions of AR infused books were investigated as well. Researchers provided a history book implementing AR and the same book without any AR content respectively to an experiment group(n=15) and a control group(n=15) composed of $3^{rd}$ and $4^{th}$ grade elementary school children. Results indicate that AR implemented reading had a positive effect on the flow of reading and interest in history, but not on acquisition of history knowledge. Also, AR-based contents were attractive to learners due to its amusing characters, sound, realistic visual motions, and vivid three-dimensional effects. Lastly, students preferred amusing interesting characters, lengthier animations and subtitles, and AR that could be seen without holding smart devices for a long while.

Pit and fissure sealants has been proven as safe and effective method of caries prevention. But improper application of pit and fissure sealant may masking the caries process in occlusal fissure. Dentists have to understand the correct and exact application method of pit and fissure sealant for he good result of caries prevention. A key factor to enhanced the effectiveness of caries prevention is retention of pit and fissure sealant. Deep penetration of material into fissure and least marginal leakage around the fissure orifice are the major concerns for dentists to achieve the successive application of pit and fissure sealants. This paper reviewed the literature on the pit and fissure sealants under the following subtitles for enhanced retention : (1) application timing, (2) Indication, (3) Occlusal prophylaxis, (4) Materials, (5) Penetration, (5) Recall check Dental profession must perform the exact application of pit and fissure sealant because this procedure is one of the most technique-sensitive one in dental field.

This paper describes the development of a network-based passenger information system(PIS) which provides the convenience of the passenger of the train and heightens the effect of the subtitle service, the advertising and the shelter guidance broadcasting against the urgent event. The existing system uses VGA signal distributor in order to broadcast information with image and subtitle and voice guidance. In this paper we improve the existing system by applying the UDP and TCP/IP protocol and use a reference clock to solve a data loss and synchronization problem which occurs in this case. We also developed an XML-based subtitle authoring tool which can edit and play the subtitles with various 3D to improve the automatic guidance broadcasting and advertisement effect according to the operation schedule of the train. The system performance was evaluated through a simulation.

With the advancement of the digital broadcasting and popularity of the Internet, recently, many studies are making on the digital watermarking for the copyright protection of digital data. This paper proposes the minimum modification method of motion vector to minimize the degradation of video quality, hiding subtitles of many language and information of OST(original sound track), character profiles, etc. as well as the copyright protection. Our proposed algorithm extracts feature vector by comparing motion vector data with watermark data, and minimize the modification of motion vectors by deciding the inversion of bit. Thus the degradation of video quality is minimized comparing to conventional algorithms. This algorithm also can check data integrity, and retrieve embedded hidden data simply and blindly. And our proposed scheme can be useful for conventional MPEG-1, -2 standards without any increment of bit rate in the compressed video domain. The experimental result shows that the proposed scheme obtains better video quality than other previous algorithms by about $0.5{\sim}1.5dB$.
