Recently, digital music retrieval is using in many fields (Web portal. audio service site etc). In existing fields, Meta data of music are used for digital music retrieval. If Meta data are not right or do not exist, it is hard to get high accurate retrieval result. Contents based information retrieval that use music itself are researched for solving upper problem. In this paper, we propose Same music recognition method using similarity measurement. Feature data of digital music are extracted from waveform of music using Simplified MFCC (Mel Frequency Cepstral Coefficient). Similarity between digital music files are measured using DTW (Dynamic time Warping) that are used in Vision and Speech recognition fields. We success all of 500 times experiment in randomly collected 1000 songs from same genre for preying of proposed same music recognition method. 500 digital music were made by mixing different compressing codec and bit-rate from 60 digital audios. We ploved that similarity measurement using DTW can recognize same music.

This paper describes about a technique of generating music from the natural motion of fish which are detected via the running averaging background subtraction method. The motion of the fish will create musical notes on a background frame which will be analyzed and played by a music playing module that is proposed in this paper called "PhysicX". This module is also capable of interacting with the fishes. in the tank.

This study is about the way of music composition which is based on S/W system and also shows the skill of moving image edit for using the composed music. The result of this contents informs the mixture of a composed music by the Midi program and a moving image for using by the S/W system, also guides many students that the Computer Music Composition and Image Edit is not a difficult sphere. It is not only a main subject but also a main goal of this study.

An advancement and wide use of portable multimedia devices make it easy to spread digital sound source, enabling users to use portable multimedia devices and search and enjoy digital sound sources and related contents. In opposition the off-line musical service market with CD stagnates gradually and in the crisis where the off-line musical service market vanishes away. In this paper, we propose the mobile music album information retrieval system which combines the barcode and a cellular phone musical service. To get digital sound sources and related information from music albums, the proposed retrieval system uses one-dimensional barcodes attached to music albums and obtains information on related albums from the sound source servers. Also, to reflect user preferences in search results, the system uses search frequency by music album, and searches albums in music genres selected by users in the order of the recent preference. The proposed mobile music album retrieval system is implemented on the basis of WIPI, and is now providing pilot services.

The current study explored if users' self-relevance of the comparison domain with creative AI robot in music composition affected their envy toward the robot, cognitive assessment toward the music and intention toward working with robot in future. This study conducted a 2 (degree of self-relevance: high(college students majoring in music) vs. low(those not majoring in music) × 2 (working type: robot-only vs. robot-human collaboration) between-subjects factorial design experiment. The findings revealed that those majoring in music did not feel envious of the robot as much as those not majoring in music. However, compared to those not majoring in music, those majoring in music evaluated the robot's creativity lower, had more negative attitude toward the music, showed less intention to use the music and work with the robots in future. No interaction between the degree of self-relevance and the working type was found.

In 21C, computer is having a powerful influence on every fields. As music field is no exception, the computer music is regarded as a next generation music. Especially the focus of 21st century's music is now moving from MIDI of 20th century to the Realtime interactive music in which computer is used as a practical instrument. Most european countries and America are doing a lot of research and performing these music. But in Korea, known as a fairly strong IT country, there is no enough perception of the importance of this new outcome of the new media era, and introduction of this music is slow as well. In this paper, we suggest the possibility of using the new way of composition by realtime interactive music in Korea. This can be a strong merit for Korean composers who want to use Korean instruments which were limited to be used as international instruments because of their restricted registers, techniques and so on.

In this paper, we propose a method of generating theme, background amd signal music usage monitoring information based on a blockchain, in which the music usage informations are recorded by the monitoring tool using feature-based filtering of monitoring organizations. Theme, background and signal music are music inserted into the broadcasting contents of broadcaster. Since they are recognized as created contents just like normal music, there are lyricists and composers who have the right for those music and all copyright holders of them have to receive the corresponding copyright fees, once the music was used in the broadcast. However, there are problems with inaccurate monitoring results for music usage, due to the omission of usage details and non-transparent settlement method. In order to solve these problems, If the information generation method proposed in this paper, accurate music usage history can be created, the details are stored in the blockchain without changes or omissions, and transparent settlement and distribution are possible by smart contract, avoiding the current non-transparent settlement method.

The influence of acquisition environment on music score images captured by a camera has not yet been seriously examined. All existing Optical Music Recognition (OMR) systems attempt to recognize music score images captured by a scanner under ideal conditions. Therefore, when such systems process images under the influence of distortion, different viewpoints or suboptimal illumination effects, the performance, in terms of recognition accuracy and processing time, is unacceptable for deployment in practice. In this paper, a novel, lightweight but effective approach for dealing with the issues caused by camera based music scores is proposed. Based on the staff line information, musical rules, run length code, and projection, all regions of interest are determined. Templates created from inverse filter are then used to recognize the music symbols. Therefore, all fragmentation and deformation problems, as well as missed recognition, can be overcome using the developed method. The system was evaluated on a dataset consisting of real images captured by a smartphone. The achieved recognition rate and processing time were relatively competitive with state of the art works. In addition, the system was designed to be lightweight compared with the other approaches, which mostly adopted machine learning algorithms, to allow further deployment on portable devices with limited computing resources.

Emergency room nurses whom exposed to more confused environment, violence, and medical disputes feel anxiety, due to increasing of demands and needs of emergency room services. Emergency room nurse anxiety needs to intervention in order to relieve emergency room nurses from anxiety, because it is an important factor that decreases job skill and satisfaction. In this paper, we examine whether to improve the effect of music intervention on emergency room nurse anxiety through appreciation of music. We used vocal music and a SAI(State Anxiety Inventory) tool for measuring the effect of music on emergency room nurse anxiety and physiological responses. Experimental results showed that vocal music intervention reduces emergency room nurse anxiety and physiological responses.

Baroque music was the birth and growth era of modern music, but it was not composed for movies. Baroque music, however, is a feature that is inserted into the movies in many different forms, leading to the overall mood and narrative, and the ability to express the characters' feeling and inner word. Therefore, in this study, five Baroque music works, including the main theme song 'Vivaldi Cantata RV.684' in the movie , are produced, and analyzed through tonal, tempo, dynamics, musical notes, tones, rhythms, musical instrument, and genre. Through analysis, we will study what epic functions and roles Baroque music plays in movies.
