Consumers changed to the subject to produce a digital contents as data transmission technique is advanced and a digital machine is diffused variously. Users are interested greatly in a user creative movie (UCM) production among various online contents. The UCM production method which uses the music and picture is the method that users make the UCM more easily. However, the UCM production service has the problem that any association does not exist in the music and picture and that the picture changes according to fixed time interval without the relation at a music rhythm. To solve this problem, we propose the UCM production method which uses a music analysis and picture analysis in the paper. A music analysis finds a picture change time according to the rhythm and a picture analysis finds the association of the picture. A music analysis finds strong parts of the sound which uses Root-Mean-Square (RMS). And a picture analysis classifies the picture as a scenery picture and people picture which uses structure simplicity of the picture(SSP) and face region detection. A picture analysis got correct result of 86.4% in the experiment and we can finds the association at each picture and arranges the sequence which the picture appears. Therefore, if we use a music and picture analysis at the UCM production, users may make natural and efficient movie.

In 2020, one after another, musicians started to hold non-contact online concerts as the pop music industry began to shrink due to the unprecedented "Covid-19" incident, in seeking for various channels and alternatives. Taking this into account, this study conducted a survey with BTS' "Bang Bang Con The Live" as the subject that was held June 2020 to see if they were qualified as an alternative format for quarantine-focused non-contact concerts. The survey was carried out with the content analysis of online concert videos participated by music experts and by collecting evaluations and alternative suggestions from the audiences. The study showed that the sample performance video well fulfilled the actual feels of offline concert elements (field visualization, face-to-face interaction, and responsive behavior), satisfaction, and convenience as an alternative concert format as an emergency correspondence. However, it was analyzed that there was a serious lack of empathy and realism with fans. Therefore, the study showed the possibility that BTS' "Bangbangcon The Live" will function as an alternative format for non-contact concerts, but suggests that measures such as supplementing digital communication systems and technology devices must be taken to be recognized as a level of settlement in the global music community as well as in Korea.

This study aimed to investigate the feasibility of an interactive singing-based synchronous videoconferencing program for children with autism spectrum disorder (ASD). This study was conducted in four stages: analysis of interactive singing tasks in the literature for children with ASD, examination of differences in perception of sounds transmitted via synchronous videoconferencing platform depending on the type of singing tasks and accompaniment, construction of singing-based synchronous videoconferencing program and determination of its validity, and implementation of the constructed program with three children with ASD and confirmation of its feasibility. The results showed that different types of singing tasks and accompaniment affected perception of sounds transmitted online, which highlights the importance of considering such effects when designing synchronous videoconferencing music therapy programs. Also, increases in program engagement and singing behaviors were observed for all three participants, and their caregivers reported high levels of satisfaction with the program. The findings support the applicability of this intervention as a tele-music alternative during the COVID-19 pandemic. Clinical implications and suggestions are discussed.

This case study aimed to investigate changes in adolescents' awareness of the motivation behind their excessive internet gaming after group music psychotherapy. Five middle school students participated in six 60-minute group sessions over 4 weeks. The group music psychotherapy program was developed to help participants understand their implicit reasons for excessive internet gaming. Verbal responses were obtained from pre-program and post-program interviews and original lyrics created by participants during program were collected for analysis. Obtained data were analyzed in terms of emotional and cognitive aspects in relation to the participants' awareness of the motivation behind their excessive gaming. The results showed that song writing as creative musical process allowed participants to be aware of positive and negative influence of gaming on themselves and express their motivation to change their perception on gaming behavior. Also, the participants reported that the use of musical product for their daily lives could be an effective coping strategy to manage their gaming behaviors and an alternative for gaming. The findings from this study support that group music psychotherapy can be an effective approach to promote awareness of adolescents' motives for excessive internet gaming and to help adolescents better manage their gaming behaviors.

In this practice article, we present the results of a scenario planning approach that is a hybrid of the three main schools of thought. Our research objective was to study the future of Interactive Digital Media applications such as online music, on-demand television and massively multi-player online role-playing games. Our approach, while essentially qualitative in nature, nevertheless draws from the rigors of the quantitative school in identifying and then tracking the significant dimensions of analysis that emerge over time as strands of events leading to plausible scenarios. Our empirical analysis revealed mapping strands to three themes - ownership, distribution and innovation - which we used in an expert validation exercise to formulate scenarios. We present and discuss the major findings and implications of this empirical investigation. In a nutshell, we conjecture that an open, competitive IDM marketplace with performance safeguards may serve both and lead to a win-win scenario. While there are differences among IDM sectors, a unified approach to regulation and policy would be effective.

국내 문화 예술 산업에서 게임과 관련된 음악 혹은 OST가 드라마, 영화, 애니메이션 등의 타 장르와는 다르게 국내의 미디어 매체에서 언급과 노출이 비교적 적은 편이다. 게임을 소비하는 일부 이용자를 제외한 일반적인 대중은 게임 음악을 접할 기회가 많지 않기 때문에 게임 음악은 여전히 문화 예술이 아닌 게임 음악이라는 틀 안에 갇혀 있다. 본 논문에서는 국내 온라인 게임과 관련된 음악의 상업성에 대해 분석하고 게임 음악이 하나의 음악 장르로 자리를 잡기 위한 방안을 제시하고자 한다.

We propose a deep learning-based beamformer combined with spectral subtraction for continuous speech recognition operating in noisy environments. Conventional beamforming systems were mostly evaluated by using pre-segmented audio signals which were typically generated by mixing speech and noise continuously on a computer. However, since speech utterances are sparsely uttered along the time axis in real environments, conventional beamforming systems degrade in case when noise-only signals without speech are input. To alleviate this drawback, we combine online beamforming algorithm and spectral subtraction. We construct a Continuous Speech Enhancement (CSE) evaluation set to evaluate the online beamforming algorithm in noisy environments. The evaluation set is built by mixing sparsely-occurring speech utterances of the CHiME3 evaluation set and continuously-played CHiME3 background noise and background music of MUSDB. Using a Kaldi-based toolkit and Google web speech recognizer as a speech recognition back-end, we confirm that the proposed online beamforming algorithm with spectral subtraction shows better performance than the baseline online algorithm.

Academic interests have long left from the field of indie musicians, despite of their social and cultural values. This also means indie musician policies have enjoyed lack of evaluation. Main purpose of this study is to understand the indie musicians' environment, music activities and their job satisfaction by employing online survey method which were conducted over 105 Korean indie musicians. Survey results show that indie musicians feel the lack of performing facilities that can hold over 50 seats. Indie musician group with experience of 6 years and more has more chances of performing at big facilities. This group also tends to play more often, and earn more money from music activities. Also, analysis shows that satisfaction level of Indie musicians is affected by two factors - music activities and social reputation. From the results, we can conclude that indie musician policy needs to build grounds to harmonize supports from various field rather than play as a single supporter. Patriarchal attitude that government should do and can do everything is no more in effective at least in indie music field.
