Personal media centered on blogs, Twitter, and Facebook has opened up a personal broadcasting area while meeting platforms such as YouTube and Africa TV. Due to the many advantages and disadvantages of personal broadcasting, a study on it was necessary and statistical survey was conducted. The study conducted opinion survey of 118 university students on personal broadcasting. As a result, we are getting news using smartphones and mainly watching videos through YouTube, and watching videos type in the order of games, music videos and sports. Satisfaction rate of video was 72.4%, 80.2% of survey did not use paid services, experiences about personal broadcasting was 96.6% and 90.5% of survey the prospect of person broadcasting of the opinion that "it will be expanded". The first thing we want to be improved in personal broadcasting is the prevention of abusive language and hate speech. Second, we were reluctant to sensational content. Third, the survey results are the improvement of excessive advertising.

In order to deal with the filtering delay problem of least mean square adaptive filter noise reduction algorithm and music noise problem of spectral subtraction algorithm during the speech signal processing, we combine these two algorithms and propose one novel noise reduction method, showing a strong performance on par or even better than state of the art methods. We first use the least mean square algorithm to reduce the average intensity of noise, and then add spectral subtraction algorithm to reduce remaining noise again. Experiments prove that using the spectral subtraction again after the least mean square adaptive filter algorithm overcomes shortcomings which come from the former two algorithms. Also the novel method increases the signal-to-noise ratio of original speech data and improves the final noise reduction performance.

In this study, we are going to discuss the role of sound, which exists as the background of a movie scene, and the relationship between seeing and hearing. In order to analyze the form in which the scene and sound are matched, the visual content of the image must be analyzed first. In this study, we analyzed Stanley Kubrick's film . Generally, there are both visual and auditory features in the scene of the movie. In some cases, the sound is emphasized more than the scene, and the scene is emphasized more than the sound. In particular, the sound in movies enables a wider imagination and a three-dimensional experience. Images and sounds will have different meanings and effects depending on the purpose of use. By analyzing the correlation between visual scene and auditory sound based on the role sound plays in the film in this study, we would like to confirm that sound is one essential element that has the role of equivalent and independent expression, not the role of assisting images.

This case study research analyzes the cross-artistic project Connect, BTS and its relationship to transmedia branding, meaning-making and spatiality. After an overview of the argument and a section on methodology, the reader will find the analysis of the case study. Thanks to the use of a qualitative approach, this examination of Connect, BTS unveils the ways in which this initiative becomes a location that allows a reconceptualization of space that fosters plurality, exchange, and subjectivity. Connect, BTS unites seemingly incompatible fields under one project, favoring the co-creation of meanings among different artists, BTS, ARMY (the group's fans), business partners and viewers. This process has been investigated through content analysis, exploring Connect, BTS's transmedia strategies from branding to storytelling, to evaluate their efficacy in regard to brand identity, brand experience, and brand trust. The paper will also explore the variety of layers and spatial dimensions contained in Connect, BTS, which flow from art to the music industry, material and digital space, various market sectors and media. In light of this, Connect, BTS embraces a galaxy of separate semantic units into an extended liminal continuum that does not discount difference.

Most of stroke patients have not only physical difficulty but speech and neurological disorder because of hemiplegia and such unexpected changes cause psychologic disadaptability and absent-mindedness. Particularly, lowering of physical ability can lead to serious emotional problem from failure or frustration in daily life. Generally, treatment of patient with stroke put emphasis on physical rehabilitation but actually this patient had considerable speech disorder such as aphasia or articulation disorder. Moreover, failing of recognition function, mental disorder as hypochondria, and even visual and auditory disorder are represented. So it is effective to integrate verbal remediation and other treatments in medical care environment. In particular, patients with language disorder very often wither psychologically therefore it is efficient to use of music therapy that gives opulent emotion to aphasia patients. And primarily to investigate the effects of 10 sessions treatments; change in spoken total number of syllables, to confirm their own value by success of given task and reassure about themselves ability. All of 10 sessions stages were scored by MIT manual and its improvement were measured, that is, accomplishment was analyzed within each level in order to prove detail change of spoken total number of syllables. The result of this program organized from 2 syllables to 4 syllables is summarized as follows. Subject A completed in preliminary stage Level I, in 2 syllables case advanced to Level III in fifth session and to Level IV in seventh session, in 3 syllables case advanced to Level III in seventh session and to Level IV in ninth session, and in 4 syllables case showed 8% low success rate in first session but after repeated practice increased considerably in sixth session and in advanced to Level III in eighth session to Level IV in tenth session. Subject B also completed in preliminary stage Level I, in 2 syllables case advanced to Level III in forth session and to Level IV in sixth session, in 3 syllables case advanced to Level III in fifth session and to Level IV in seventh session, and in 4 syllables case showed 10% low success rate in first session and increased considerably in fifth session and in advanced to Level III in seventh session but could not reach to Level IV until tenth session. As a result, it was shown that music therapy using MIT was not statistically meaningful but improved spoken total number of syllables and success rate of task had improved as a whole. Therefore, music intervention using MIT it has positive affect on verbal ability of patients with Broca's Aphasia and their language rehabilitation.

This study introduced the concept of 'Media-content repertoire', which indicates the set of favorite media-content combinations of media users and extracted five media user types based on those combinations. We used the range of media(i.e., smartphone, tablet, PC, and TV) and entertainment content(i.e., movie, broadcasting, music, and game) for the analysis. Also, we investigated the differences between those types including demographic variables, individual characteristics, and content buying behavior and we found that statistically significant differences exist among them. Those include 'non-user'(i.e., lower level of media use), 'screen user'(i.e., 50s, TV-centered media use), 'variety seeker'(i.e., 20s. heavy public transport user), 'selective focus'(i.e., 20,30s, movie&broadcasting-centered media use), and 'heavy user'(i.e., high level of media use and consumption). The results provide both academic implications(e.g., extension of media repertoire concept) and practical implications(e.g., direction to the target marketing for each user type).
