Dynamic Compressors in vocal recordings of modern pop music are essential equipment. Dynamic compressors are applied not only to the mix for listening to music but also to the monitor for the singer to listen to his voice along with the accompaniment while the singer is recording. This study is an experimental study on the effects of a dynamic compressor applied to a monitor environment on the vocal performance of a singer. 10 participating singers participated in the blind test to test how the vocals heard through the monitor would be affected by the 1:1, 2:1 and 4:1 compression ratio. Experimental results show that the higher the compression ratio applied to the monitor, the bigger the song, the brighter the tone, but the pitch becomes finer inaccuracy on the bigger dynamic part of the song. In post-interviews with blinds, it was found that singers generally preferred to hear compressed sound through a compressor on the monitor. Since the music used in the experiment was a ballad with a wide dynamic range, it could not be generalized to all kind of music recordings, but it could provide important implications for the monitoring of recording sites. In addition, We hope that the cognitive science approach to recording technology will be added based on this paper which has been studied through empirical studies on the effect of the monitor environment on the singing voice.

The purpose of this study is to examine how Korean dance affects middle-aged women by acting as a cultural mediator. A qualitative approach was taken in order to best achieve the purpose of this study. The data used in this study were collected from Feb 10th to April 1st, 2016, using in-depth interviews. The results are as follows; firstly, on an emotional level, the middle-aged women participating in Korean dance as a cultural mediator, feel a sense of self-achievement and social belonging, as well as experiencing an improvement in their psychological stability by resolving their depression. Those who had lost their sense of autonomy and productivity were able to recover some of their self-esteem through this activity. Secondly, in terms of their activity, the Korean dance enabled the ladies to exercise their poorly used muscles by strengthening their gross and fine motor skills through the movements associated with the Korean traditional music. This allowed them to ease their chronic physical pain and it can be considered that their overall exercise function was increased by expanding their exercise radius. Third, in the cognitive area, it was possible for them to revive their happy memories by listening to the music which was loved by their preceding generations. This is because the melody of familiar Korean music provides them with the chance to remember their former days. Lastly, in the social area, the Korean dance allowed the middle-aged women to accept themselves through music and movement, as well as playing the role of a mediator which enabled them to overcome their isolation and the conflicts they face in their social relations. In addition, they achieved self-realization by reconnecting with the regional community through the Korean dance performances, which they learned as social community members.

In this paper, correlation analysis between speech characteristics and the dose of antipsychotic drugs was performed. To investigate the pattern of speech characteristics of ExtraPyramidal Symptoms (EPS) related to voice change, a common side effect of antipsychotic drugs, a Korean-based extrapyramidal symptom speech corpus was constructed through the sentence development. Through this, speech patterns of EPS and non-EPS groups were investigated, and in particular, a strong speech feature correlation was shown in the EPS group. In addition, it was confirmed that the type of speech sentence affects the speech feature pattern, and these results suggest the possibility of early detection of antipsychotics-induced EPS based on the speech features.

As the sound art field is keep growing and expanding, we shall contemplate from the sociology of the arts and cognitive science point of views to wisely accept and properly appreciate various artistic works and practices. It is because the value evaluation of new arts shall substantially involve analysis and inspections with considerations of today's complex environments, the creative productions, and the consumptions; because, such critiques are necessity for the advancement of new arts. This paper briefly introduces reasoning of including sociological analysis and criticism in evaluating sound arts beyond dichotomy of the fine arts and music fields. It also looks into changes and conditions of cultural arts grants and allowances of the interdisciplinary art genre in South Korea as it has been almost alone a playground for its domestic creative practices of the sound art. This paper is written in a hope to suggest some possible directions for future developments of these contemporary borderless and/or experimental arts.

This case study aimed to develop a therapeutic rap protocol based on narrative components for improving discourse skills of adolescents with mild intellectual disability (ID) and to explore its applicability. The protocol matched narrative elements (background, initiating event, internal response, attempts, and reaction) with rap components (verse, hook, and interjections), guiding participants to narrate their experiences in a connected discourse form. The protocol was also structured to gradually increase in difficulty, considering the developmental levels of adolescents with ID and it included steps for understanding discourse structures, applying narrative elements to content creation, and expanding narratives. Post-intervention analysis of the stories and rap lyrics created by participants to express their real-life experiences showed that participants increased the length of their stories and rap compositions, with notable improvements in rhythmicity and the inclusion of narrative elements. These findings suggest that, instead of constructing rap from random utterances, providing a structured framework reflecting discourse structure enhanced participants' understanding of event context and logical connections. Furthermore, the various elements and rhythmic features of rap can strengthen motivation and organization in discourse. This study highlights the therapeutic potential of rap in addressing the unique developmental needs of adolescents with mild ID, thereby diversifying and systematizing music therapy interventions for this population.

Motion graphic is also developing into its own genre in graphic design by establishing individual industrial fields. images and graphics but also recognize even motions and sounds as communication elements delivering a message. Nevertheless, web communication designers have yet to experimentally test the visual motion priniciples or the audio sound expressions in terms of technology. If the dance are used, they may be new communication approaches in the age of multi-media, which allows for communication of visual and audio information or images. With such conceptions in mind, this study was aimed at reviewing the structural relationship between visual motion principles of the kinetic and the sound images to combine the audio and video effects. To this end, the basic structure of dance and music were substituted into the dance to determine their relevancy, and thereupon, examine the effective sound expression methods and techniques depending on movements of the objects in the monitor. Thus, this study, by inquiring into the uniqueness of choreography in motion graphic, presents the possibility of limitless expression of designer creation and inner world, and the ultimate goal lies in assuring the artistic value of motion graphic and its position as a synthetic art.

Patients with neurocognitive disorder show behavioral psychological symptoms such as agitation, aggression, depression, and wandering, as well as cognitive decline, which puts a considerable burden on patients and their families. For the treatment of behavioral psychological symptoms, patient-centered, non-pharmacological treatment should be used as a first line approach. This paper describes non-pharmacological interventions to manage and treat behavioral psychological symptoms in patients with neurocognitive disorder. In order to control behavioral psychological symptoms such as agitation, depression, apathy, insomnia, and wandering, it is important to identify and evaluate factors such as environmental changes and drugs, and then solve such problems. Non-pharmacological interventions include reassurance, encourage, distraction, and environmental change. It is necessary to understand behavior from a patient's point of view and to approach the patient's needs and abilities appropriately. Reminiscence therapy, music therapy, aroma therapy, multisensory stimulation therapy, exercise therapy, light therapy, massage therapy, cognitive intervention therapy, and pet therapy are used as non-pharmacological interventions, and these approaches are known to improve symptoms such as depression, apathy, agitation, aggression, anxiety, wandering, and insomnia. However, the quality of the evidence base for non-pharmacological approaches is generally lower than for pharmacological treatments. Therefore, more extensive and accurate effectiveness verification studies are needed in the future.

This paper deals with an efficient method for skipping inter-channel phase differences (IPD) in the MPEG surround of the unified speech and audio coding (USAC). Based on the psycho-acoustic sensitivity on the IPD, we estimate a threshold on IPD, below which we can not notice degradation in spatial cue. We propose an IPD skip method, in which any IPDs within the threshold are set to zero and are not transmitted. The proposed IPD skip method gives about 38% savings in terms of bit amount for IPD. Nevertheless, in the MUSHRA test, the proposed method does not show any noticeable degradation in the decoded audio quality.

The development of digital technology and the Internet has brought about a great change in the content industry. In order to keep pace with these changes, the copyright law has undergone several revisions, and the concept of "digital sound transmission" was introduced in the 2006 revision. However, in the current law, digital audio transmission is problematic in that the criteria for distinguishing between broadcasting and transmission is abstract and unclear. This ambiguity makes it difficult to judge the legal status of new music webcasting service such as "Free Litsen". Although these services are positioned as digital audion transmission, they have created a new concept of pseudo transmission because of its similarity to the audio transmission in its convenience and utility. These problems stem from the imbalance of between the development of technology and the legal system, so the change of the legal system is inevitable. Thus, this study discusses US copyright law and related cases, and then suggests solutions for pseudo transmission problems. This study suggests legislative criteria for pseudo transmission problems and legislative measures that can reduce the actual damage to the music market.

The purpose of this study is to analyze how the movie <The Book of Fish> (2021) represents Joseon, which is slowly collapsing with the Neo-Confucian order of the 19th century shaking, and to discuss its meaning. Prior to the analysis, the analysis framework of the historical drama was presented considering the narration characteristics of the historical drama. Using the analysis framework of historical dramas, we confirmed that <The Book of Fish> is representing the image of Jeong Yak-jeon and Jang Chang-dae living their lives as independent individuals between the limitations and possibilities of the times based on the plot structure of the narrative of exile. Through the central memory and surplus memory created through plot and style elements such as contrast between black and white and color images, voice-over narration, chinese poetry subtitles and music, the film asks us universal questions about what it takes to live as an independent individual.
