In spite of controversial debates on aesthetic issues of computer-generated electronic music, rapid advancement of music technologies in the past decade have resulted proliferation of using virtual software synthesizers and samplers in music composition. Computer-based music production platform has become not only a norm among some of contemporary music composers but also vital apparatus for their compositional process. There are two imperative parts of this compositional process involving sampling in computer-based music production, which are commercially available sample libraries that include pre-recorded audio samples, and music production software that processes them. The purpose of this study is to investigate the process and effectiveness of reconstructive compositional process utilizing distinctive features of sampling on computer music production software. This study addresses issues such as: the definition of audio sampling, how sampling is incorporated in compositional process, and what features of music production software are particularly effective in various musical expressions. The result of this study will hopefully accommodate and fulfill the needs of electronic and acoustic musicians' creativeness.

Music sampling, which has been popular since hip-hop DJs used it in the 1970s, is now one of methods of producing music that is used regardless of genre or country. In this study, an overall production methodology for music sampling was presented through in terms of content and techniques. First of all, in terms of the contents, we classified them into the reuse and length of materials, and the function of samples in the mixed songs. In terms of the techniques, editing and effecting techniques were classified. By combining these elements, the methodology of music sampling applicable to the productions as well as the analysis was presented. Based on this methodology, the sampled songs of Korean Popular musicians - Jang Ki-ha and Faces, Epik High, The Quiet, and DJ DOC - were successfully analysed. Through the analysis process, the organic relationship of elements within the methodology was investigated, and the results of the analysis showed the effectiveness of the proposed methodology. This study can be meaningful in laying the groundwork for applying music sampling directly when actually producing songs or analyzing sampled songs.

Composing music is an inspired yet challenging task, in that the process involves many considerations such as assigning pitches, determining rhythm, and arranging accompaniment. Algorithmic composition aims to develop algorithms for music composition. Recently, algorithmic composition using artificial intelligence technologies received considerable attention. In particular, computational intelligence is widely used and achieves promising results in the creation of music. This paper attempts to provide a survey on the music generation based on the Monte Carlo (MC) algorithm. First, transform the MIDI music format files to digital data. Among these data, use the logistic fitting method to fit the time series, obtain the time distribution regular pattern. Except for time series, the converted data also includes duration, pitch, and velocity. Second, using MC simulation to deal with them summed up their distribution law respectively. The two main control parameters are the value of discrete sampling and standard deviation. Processing the above parameters and converting the data to MIDI file, then compared with the output generated by LSTM neural network, evaluate the music comprehensively.

In this paper, we propose an analysis of the sound source of virtual orchestral music in detail by using the production technology of sampling and playback, and technical experiments and verification for the most advanced Hollywood Library series of timbre and the timbre production and control technology of Vienna instrument Pro and other softwares, to find their solutions and come up with the best timbre production method for orchestral music from the perspective of the specific design ideas of the productions of virtual orchestral instruments. The so-called virtual orchestral instruments are non-real orchestral instruments, which are based on the imitation of timbre of real orchestral instruments, processed and synthesized through the scientific and technological means, and produced by the use of electronic equipments or computers. The study of virtual timbre production technology is very important, and it is like the study of composers' creative techniques. Not only scientific and advanced timbre production methods can be obtained from the study, but also new ways of future timbre production are expected to be explored.

In this research, we estimated the number of hits per song and its sampling error from 11 (areas including Gangnam) based on log data compiling the number of hits collected from offline karaoke players in March 2011. Then, we calculated the monetary equivalent of the sampling error under the current system that distribute royalties from the karaoke players to copyright holders(song writers and arrangers) according to the estimated hits. Because of the small sample size, the estimated number of hits had a very large sampling error. This research proposes a more reasonable sample design to estimate the usage of copyrighted music works for a fair distribution of royalties by reducing sampling error.

Objective: The purpose of this study is to develop a music making program that utilizes the characteristics of the picture books medium through the ADDIE model so that teachers can easily apply it to children, and to determine whether it affects children's musical aptitude and music creativity. Methods: The Participants of the study were 42 five-year-old children attending a daycare in Seoul, of which 20 were in the experimental group and 22 in the comparative group. The experimental group participated in a music production program using picture books, and during the same period, the comparison group participated in music activities suggested by the Nuri Course. Using the SPSS 22.0 program, average, standard deviation, independent sampling t-test, and ANCOVA(Analysis of Covariance) were calculated. Results: The music making program using picture books improved children's rhythm and tone which are the sub-items of music aptitude. The music making program enhanced children's music flexibility, music creativity, music logic which are the sub-items of music creativity. Conclusion/Implications: The music making program presented systemic teaching-learning method with which teachers explained the modeling and practiced from simple activities to various activities repeatedly in order to make teachers approach music making more easily. It is recommendable to make the music making program by using I-pad and computers.

Objective: The reason why it is important to look at the benefits of exercise-music experience perceived by the elderly is that the satisfaction of life in old age is a meaningful reflection of the subjective perception of the life of the elderly. This is because it must be understood as the center. Design: A qualitative study. Methods: Participants are senior citizens attending senior citizens' college located in Eumseong city. Those who have taken an exercise-music song program for at least one semester served as the participants. Individual interviews were conducted by selecting 10 people through purposeful sampling. The collected data were analyzed by applying Colaizzi's method among phenomenological methods. The exercise-music program was conducted for 12 weeks, for a total of 50 minutes for each time (10 minutes for introduction, 35 minutes for music, 5 minutes for finishing). Results: As a result of the study, the experience of the exercise-music program was derived into 6 categories and 13 subjects. These 6 main categories are 'Changes from the developmental crisis', 'Freedom from the confines of others', 'Positive emotions found through songs', 'Feeling of peer and fellowship relationships', 'Changes in self-awareness', It appeared as a 'Change in the way of life'. Conclusions: In conclusion, the experience of the exercise-music program brought about a positive changes in life of doing one's best by improving confidence and confirming presence. Therefore, this study suggests activation of senior college programs to find a sense of presence for each level by using exercise-music programs with good accessibility.

Purpose: The purpose of this study was to examine the effects of a preference music therapy on anxiety and pain of cystoscopy. Methods: This study was performed using the quasi-experimental study design with non-equivalent control group pre-test and post-test. Total of 76 adult clients admitted to a tertiary hospital located in Daegu, South Korea were selected by convenience sampling 19 in the control and 57 in the experimental group. The data were analyzed by $x^2$, t-test, paired t-test, and repeated measures ANOVA using SPSS 17.0. Results: Implementing a preference music therapy was found to be effective in reducing anxiety level before cystoscopy in the present study. However, there were no significant effects of this preference music therapy in reducing pain and anxiety during cystoscopy. In addition, there were no significant effects of a preference music therapy on the patients' satisfaction of the anxiety, discomfort, and pain relieving. Conclusion: The findings support that implementing a preference music therapy may reduce anxiety before the cyctoscopy procedure. Therefore, it can be suggested that a preference music therapy needs to be consider-ed as a regular nursing intervention to reduce patient anxiety level before cystoscopy.
