The purpose of this study is to confirm the use of smartphones by children aged 3 to 5 years old and to propose a plan for prevention of overdependence. To this end, the data of 909 people aged 3 to 5 years old were used in the study from the raw data of the '2019 Smartphone Overdependence Survey' conducted by the National Information Society Agency. The research results are as follows : Infants aged 3 to 5 were using their smartphone for an average of more than an hour a day, it was found that smartphones were used in the order of video services and games, listening to music, educational contents and search services. Parents were found to be tolerant of their children's smartphone usage time and dependence. In particular, despite the fact that most infants and toddlers use smartphones to watch videos and use game content, they are not concerned. Therefore, parental education content for the use of smartphones by infants and toddlers needs to include comprehensive content on media use.

Bandwidth Extension refers to restoring and expanding a narrow band signal(NB) that is damaged or damaged in the encoding and decoding process due to the lack of channel capacity or the characteristics of the codec installed in the mobile communication device. It means converting to a wideband signal(WB). Bandwidth extension research mainly focuses on voice signals and converts high bands into frequency domains, such as SBR (Spectral Band Replication) and IGF (Intelligent Gap Filling), and restores disappeared or damaged high bands based on complex feature extraction processes. In this paper, we propose a model that outputs an bandwidth extended signal based on an autoencoder among deep learning models, using the residual connection of one-dimensional convolutional neural networks (CNN), the bandwidth is extended by inputting a time domain signal of a certain length without complicated pre-processing. In addition, it was confirmed that the damaged high band can be restored even by training on a dataset containing various types of sound sources including music that is not limited to the speech.

The Manual for Buddhist Rituals (1935) is the manual of Buddhist rituals which has a pivotal position in terms of the modernization of Korean Buddhist rituals. The text has been established through the contents and systems of the two texts, The Manual for Practising Rituals (作法龜鑑, 1827) and the Compulsory Manual for Buddhists (佛子必覽, 1931). These three manuals include the examples for practising the Manuals. The analysis of the examples for the practices of the three texts is as follows: The Manual for Practising Rituals tries to include the Sounds of the Music for the Buddhist Rituals through the Four Sounds (四聲) and the Twin words (儷語); the marks of the sounds are excluded after the compulsory Manual for Buddhists. The Manual for Buddhist Rituals has replaced the rituals for repentance (三寶通請) with the rituals for revering (四聖禮): and this text has made it easier that people participate in Buddhist rituals with the text which is written in bilingual format in Korean and Classic Chinese. The text has been popularized through above-mentioned changes against the previous two texts but it has ended up excluding the practices for the music of Korean Buddhism such as the music for Buddhist rituals (梵唄) and reciting the name of Buddhas (念佛).

The present study applied the IPA(Importance-Performance Analysis) to derive several practical alternatives for the improvement of Chuncheon Silver Orchestra program using IPA(importance-performance analysis). Most importantly, this work performed a comparative study using sample data collected from two groups of silver member(N=53) and program operator(N=32). A careful literature review leaded to the development of six types of evaluation sectors, including 'connection with the local community', 'budget operation', 'program operation', 'manpower operation', 'public relations strategy' as well as 'environment for program operation'. This work further devised twenty-two evaluation items. The results indicated that silver member group rated 'manpower operation' the highest in their both perceived importance and performance. Program operator group rated 'budget operation' and 'manpower operation' rated the highest in their perceived importance and performance, respectively. The results form IPA matrix analysis provides an important implication that much efforts and interests should be sustainably given from the perspective of the silver member group and the program operator group coupled with four types of IPA quadrant, accordingly.

Documentaries based on facts not only contain the spirit of that era but have been transformed in various ways according to changes in technologies and media. This study analyzed under the premise that the original documentary of YouTube plays a role in representing the characteristics of the medium. YouTube's original documentary is released on YouTube and then re-edited and released as a documentary film, and has the same shooting source, and is edited and described differently depending on whether it is a YouTube or a movie. This is the content that can confirm the media differences between YouTube documentary and documentary film. The cinema version shows the difference in that the narrative is developed using third-person narration and subtitles, mainly for handheld shooting and smooth editing, and the YouTube version is developing the narrative centering on audio-centric rough editing, interviews and background music. Through this, it can be seen that the YouTube version reinforces intimacy through a personal and direct expression method, while the cinema version reinforces objectivity through an official and indirect expression method.

The talk of today's era is innovation and convergence. Convergence can be seen as innovation because convergence is born through innovation and innovation is made through convergence. Crossover and collaboration (collectively referred to as "crossover") which are used as a concept of convergence in popular culture means the combination and integration of different genres or fields, and has recently been used in various fields such as movies and music. The use of crossover helps to break boundaries with other fields and create new works through free and diverse attempts. Thus, in this study, the convergence of popular culture, or crossover, is analyzed in conjunction with the Korean horror genre. Currently, Korean horror movies were popular from the 1990s to the early 2000s, but now only a few are coming out due to a series of poor box office performances. However, according to this study, crossover attempts have already begun in Korean horror films, and traces of crossover have been found in several successful films. In this study, we will further apply a collaboration of characters such as "Avengers" to present a new direction for Korean horror movies.

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.
