The Fast Imaging Solar Spectrograph (FISS) on the Goode Solar Telescope (GST) at Big Bear Solar Observatory is the imaging Echelle spectrograph developed by the Solar Astronomy Group of Seoul National University and the Solar and Space Weather Group of Korea Astronomy and Space Science Institute. The instrument takes spectral data from a region on the Sun in two spectral bands simultaneously. The imaging is done by the organization of intensity data obtained from the fast raster scan of the slit over the field of view. Since the scan repeats many times, the whole set of data can be used to construct the movies of monochromatic intensity at arbitrary wavelengths within the spectral bands, and those of line-of-sight velocity inferred from different spectral lines. So far there are two standard observing configurations: one recording the $H{\alpha}$ line and the Ca II 8542 line simultaneously, and the other recording the Na I D2 line and Fe I 5435 line simultaneously. We have developed the procedures to produce the standard data for each observing configuration. The procedures include the spatial alignment, the correction of spectral shift of instrumental origin, and the lambdameter measurement of the line wavelength. The standard data include the movie of continuum intensity, the movies of intensity and velocity inferred from a chromospheric spectral line, the movies of intensity and velocity inferred from a photospheric line. The processed standard data will be freely available online (fiss.snu.ac.kr) to be used for research and public outreach. Moreover, the IDL procedures will be provided on request as well so that each researcher can adapt the programs for their own research.

This paper is a study of the film A Deaf, Sam-ryong by Na Un-kyoo released in 1929 at Choseon theater. This study compared the partial scenes of the currently remaining A Deaf, Sam-ryong with related scenarios and original works, after the restructuring of the structure of A Deaf, Sam-ryong and was written for the purpose of reviewing it. The film A Deaf, Sam-ryong is based on Na Dohyang's novel A Deaf, Sam-ryong. However, in the process of adaptation, it was a work that strongly reflected the intention of Na Un-kyoo as a scenario writer. The study of these intentions has to reorganize the remaining scenes at present and rely on research methods to compare them with related scenarios or original works. Even if a situation that makes it difficult to draw clear conclusions is drawn in this research process, we can not but dismiss the method of this research itself if we can not stop the purpose of restoring the loss of Korean cinema. As a result, this study is devised to carry out this study, which had been discontinued due to the lack of work and related data so far.

We investigate the dynamic relationships among digital piracy activities, TV ratings, and online buzz for Korean TV dramas using a panel vector autoregression model. Our main findings include 1) TV ratings are negatively affected by digital piracy activities but positively affected by google buzz, 2) digital piracy activities are negatively affected by TV ratings and social buzz, and 3) social buzz and google buzz are positively influenced by each other. While many empirical studies were conducted to reveal the effects of music or movie piracy, our understanding of drama piracy is limited. We provide empirical evidence of the dynamic relationships between drama piracy, TV ratings, and online buzz. Our findings show the presence of indirect piracy effects on TV ratings through online buzz. Further, we reveal that social buzz and google trends play different roles in promoting TV ratings and piracy activities. We discuss the implications of our findings for theory and practitioners.

This article aims to examine the Sinpa of Along With the Gods: The Two Worlds. Along with the Gods: The Two Worlds was a box office hit with a 10 million attendance mark, but it was also criticized as a 'Korean Sinpa' at the time of its release. The original version of Along with the Gods is a Webtoon called Singwahamkke in Korean. The popularity of Singwahamkke and its adaptation, Along with the Gods was enormous, which prompted a very active research to be carried about the work. However there are only a few articles which analyze the Along with the Gods: The Two Worlds focusing on the Sinpa, even though the Sinpa of the Along with the Gods: The Two Worlds was a highly controversial issue when the movie was released. In this regard, this article tries to examine the Sinpa of the Along with the Gods: The Two Worlds closely, especially by comparing it with the original webtoon Singwahamkke Jeoseung. The body part of this article is composed of three major parts: chapters 2, 3, and 4. Chapter 2 contains an in depth explanation about the notion of Sinpa, the main conceptual research tool for this study. In chapter 3, the original webtoon Singwahamkke Jeoseung is examined closely. This chapter analyzes the 'Sinpajeok moment' in Singwahamkke Jeoseung and argues that despite the presence of Sinpa elements, the webtoon cannot be considered a 'Sinpajeok text'. On the other hand the main subject of chapter 4 is discovering what effect the adaptation from webtoon to movie had on this work, with a particular focus on the gender of Sinpa and Kim Ja-hong. Chapter 5, which corresponds to the conclusion, briefly evaluates the social significance of the controversy arisen in South Korea about the Sinpa in Along with the Gods: The Two Worlds. Sinpa is one of the most repeated code in the realm of Korean popular narrative. This is why the Sinpa of contemporary text is examined continuously even though there are already plenty of studies on the Sinpa. Everyone has called Along with the Gods: The Two Worlds Sinpa but no one has properly analyzed it. It is hoped that this article which closesly examined the Sinpa in Along with the Gods: The Two Worlds contribute to the field of Sinpa. It is also expected that this article can find appropriate contextual meaning of the series of Along with the Gods.

This study analyzes Kureougy Balmyungwang (Prankster Invention King), produced by Chung-ki Kim in 1984. [Prankster Invention King (Kureougy Balmyungwang)] has been known as science education film. However, around the time this film was produced in 1980s in South Korea, Science and Technology is basis for development of nation driven by military dictatorship for increasing national welfare and individual capability. In this regards, Kureougy Balmyungwang (Prankster Invention King) is an animated movie not only about education and science, but also a propaganda describing children making every effort to develop their country by scientific research. In this regards, this film is in accordance with Director Kim's other animated films such as General Toli, who also served for the government, advertising its policy. This article compares and analyzes Kureougy Balmyungwang (Prankster Invention King) with various propaganda works after World War I, to clarify the propaganda characteristic and contemplate the contemporary meaning of this work.

Sentiment lexicon is an essential element for expressing sentiment on a text or recognizing sentiment from a text. We propose a graph-based semi-supervised learning method to construct a sentiment dictionary as sentiment lexicon set. In particular, we focus on the construction of domain-specific sentiment dictionary. The proposed method makes up a graph according to lexicons and proximity among lexicons, and sentiments of some lexicons which already know their sentiment values are propagated throughout all of the lexicons on the graph. There are two typical types of the sentiment lexicon, sentiment words and sentiment phrase, and we construct a sentiment dictionary by creating each graph of them and infer sentiment of all sentiment lexicons. In order to verify our proposed method, we constructed a sentiment dictionary specific to the movie domain, and conducted sentiment classification experiments with it. As a result, it have been shown that the classification performance using the sentiment dictionary is better than the other using typical general-purpose sentiment dictionary.

A big success of the 3D film 'Avatar' in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..

In this paper, we propose a DNN based speech detection system using acoustic characteristics and context information of media audio. The speech detection for discriminating between speech and non-speech included in the media audio is a necessary preprocessing technique for effective speech processing. However, since the media audio signal includes various types of sound sources, it has been difficult to achieve high performance with the conventional signal processing techniques. The proposed method improves the speech detection performance by separating the harmonic and percussive components of the media audio and constructing the DNN input vector reflecting the acoustic characteristics and context information of the media audio. In order to verify the performance of the proposed system, a data set for speech detection was made using more than 20 hours of drama, and an 8-hour Hollywood movie data set, which was publicly available, was further acquired and used for experiments. In the experiment, it is shown that the proposed system provides better performance than the conventional method through the cross validation for two data sets.

This study was to assess the lifetime cancer and non-cancer risk of exposure of worker and user at public facilities in Korea to volatile organic compounds (VOCs). We measured the concentrations of two aldehydes and five VOCs in indoor air at 424 public buildings that 8 kinds of public facilities (70 movie theaters, 86 offices, 86 restaurants, 70 academies, 22 auditoriums, 30 PC-rooms, 30 singing-rooms and 30 bars) all over the country. There were estimated the human exposure dose and risks with averages of the using-time and frequency for facility users and office workers, respectively. Carcinogens (formaldehyde, acetaldehyde, and benzene) were estimated the lifetime excess cancer risks (ECRs). non-carcinogens (toluene, ethylbenzene, xylene, and styrene) were estimated the hazard quotients (HQs). The average ECRs of formaldehyde and benzene for facility worker and user were $1{\times}10^{-3}{\sim}1{\times}10^{-4}\;and\;1{\times}10^{-4}{\sim}1{\times}10^{-5}$ level, respectively, in all facilities. HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities. The estimated ECRs for restaurant and auditorium were the highest, and the PC-room and bar were the next higher facilities. Furthermore, people in a smoking facility had the highest cancer risk. Higher ECRs of formaldehyde and benzene were observed in indoor smoking facilities such as restaurant and auditorium. Higher HQs of toluene and xylene were observed at the restaurant and office building.
