This paper deals with the development of an application that converts the PDF music score entered by the user into a MIDI file of the chord the user wants. This application converts the PDF file into a PNG file for chord conversion when the user enters the PDF music score file and the chord which the user wants to change. After recognizing the melody of sheet music through image processing algorithm and recognizing the tempo of sheet music notes through deep learning, then the MIDI file of chord for existing sheet music is produced. The OpenCV algorithm and deep learning can recognize minim note, quarter note, eighth note, semi-quaver note, half rest, eighth rest, quarter rest, semi-quaver rest, successive notes and chord notes. The experiment shows that the note recognition rate of the music score was 100% and the tempo recognition rate was 90% or more.

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.

The purpose of this study was to evaluate the effect of music therapy on the state anxiety and the vital signs in ophthalmic inpatients experiencing momentary visual disturbance. The patients listened to the music for or over 30 minutes a time for 3 days The subjects for this study were twenty-eights experiencing momentary visual disturbance in ophthalmic department of a hospital in Kwangju. They were assigned to two groups, fourteen to a experimental group and fourteen to a control group. The data were collected from November 22 to December 4, 1999 by means of state anxiety scale questionnaire and measurement of vital signs. The data were analyzed with SPSS programs. The results were as follows; 1. There were significant differences between the two groups on anxiety score after music therapy(t=-2.95 p=.007). 2. The first hypothesis that the experimental group who received music therapy would have less anxiety score than the control group who did not receive music therapy was supported (t=8.98, p=.000). 3. There were no significant differences between the two groups on change of vital signs after music therapy. 4. The second hypothesis that the experimental group who received music therapy would have more relived vital signs than the control group who did not receive music therapy was not supported. In conclusion, music therapy can be effective nursing intervention in decreasing anxiety of ophthalmic in-patients experiencing momentary visual disturbance.

Recognition systems for scanned or printed music scores that have been implemented on personal computers have received attention from numerous scientists and have achieved significant results over many years. A modern trend with music scores being captured and played directly on mobile devices has become more interesting to researchers. The limitation of resources and the effects of illumination, distortion, and inclination on input images are still challenges to these recognition systems. In this paper, we introduce a novel approach for recognizing music scores captured by mobile cameras. To reduce the complexity, as well as the computational time of the system, we grouped all of the symbols extracted from music scores into ten main classes. We then applied each major class to SVM to classify the musical symbols separately. The experimental results showed that our proposed method could be applied to real time applications and that its performance is competitive with other methods.

The purpose of this study was to identify the effect of music therapy on state anxiety, perception of pain of dental patients. The subjects consisted of forty patients undergoing dental treatment at one dental clinic. Twenty eight of them were assigned to the experimental group, while twelve subjects to the control group. The data were collected from June 29 to August 1, 1998 by means of a state anxiety scale (by Spielberger) questionnaire and visual analog scale for pain measurement. The data were analysed with $X^2$-test, t-test, and paired t-test. The results are as follows 1) There were no significant differences between the experimental and the control group on the post treatment the state anxiety score. However, in the experimental group, the state anxiety score decreased significantly after music therapy(t=3.19, p=0.003). In the control group, the state anxiety score did not decrease significantly(t=1.65, p=0.126). Especially, high score group on the state anxiety was found to be of significant differences in the experimental group (t=3.09, p=0.007). 2) There were no significant differences between the experimental and the control group on the post treatment perception of pain. However, after music therapy, the experimental group had a lower post treatment perception of pain than the control group. 3) After music therapy, subjective response of the experimental group was one of relative contentment. From these results, it is concluded that music therapy as a nursing intervention can be effective in decreasing anxiety in dental patients.

Today, mobile phone is a necessity of modern life. For that reason, we suggest a particular system of a mobile phone which take a picture of music score image and automatically play it without any technical knowledges about the music score information. This experiment makes midi, acknowleging separate symbols via preprocessing to music score image taken. This paper utilizes 11 sorts of the score image taken by a mobile phone camera for this experiment. Through this method we suggest, as much as 98% on average takes place, which is very high recognizing ratio. Also, as we introduce this system in a mobile phone by porting, it takes 8.63 seconds on average to create midi following input of images.

This paper describes an analysis of the music as a time series and the fuzzy logic-based modeling of it. All music is made up of a finite number of musical notations known as the musical symbols, such as clefs, staff, tine signature, notes, rests, etc. . The musical score uses musical symbols to present various characteristics, such as rhythm, melody, chord, etc,. for interpreting the music. In this paper, it is possible to transform the beat and pitch in the musical into time series from the viewpoint of recognizing beat and pitch of sounding tone at each time. On the basis of the identified features of the musical score, a musical score is represented as a time series and then is constructed to fuzzy logic-based model for predicting them. Examples are presented to illustrate the validity of the proposed method.

Background: Many studies have pointed to strategies to cope with patient anxiety in colposcopy. Evidence shows that patients experienced considerable distress with the large loop excision of transformation zone (LLETZ) procedure and suitable interventions should be introduced to reduce anxiety. This study aimed to investigate the effects of music therapy in patients undergoing LLETZ. Materials and Methods: A randomized controlled trial was conducted with patients undergoing LLETZ performed under local anesthesia in an out patient setting at Ramathibodi Hospital, Bangkok, Thailand, from February 2015 to January 2016. After informed consent and demographic data were obtained, we assessed the anxiety level using State Anxiety Inventory pre and post procedures. Music group patients listened to classical songs through headphones, while the control group received the standard care. Pain score was evaluated with a visual analog scale (VAS). Statistical analysis was conducted using Pearson Chi-square, Fisher's Exact test and T-Test and p-values less than 0.05 were considered statistically significant. Results: A total of 73 patients were enrolled and randomized, resulting in 36 women in the music group and 37 women in the non-music control group. The preoperative mean anxiety score was higher in the music group (46.8 VS 45.8 points). The postoperative mean anxiety scores in the music and the non-music groups were 38.7 and 41.3 points, respectively. VAS was lower in music group (2.55 VS 3.33). The percent change of anxiety was greater in the music group, although there was no significant difference between two groups. Conclusions: Music therapy did not significantly reduce anxiety in patients undergoing the LLETZ procedure. However, different interventions should be developed to ease the patients' apprehension during this procedure.
