The purpose of this study is to examine the effects of a chorus program in a local child center regarding character, social skills, problematic behaviors, and ADHD. Subjects of this study included 24 children in elementary schools participating in the daytime programs at a local child center located in Suwon, South Korea. The chorus program was comprised of 12 sessions of 60 minutes each, conducted from April 5-July 5, 2017. Results of this study were as follows: First, during the interviews on the character of the children before and after participation in the chorus program, it was noted that the children became more active in terms of the relationships with others and leadership. However, it was also noted that children were more active at the center than they were at their schools. Second, the differences in social skills before and after the chorus program among children were significant in overall social skills and their sub-variables, indicating that there were effective in adjusting social skills. Third, the differences in problematic behaviors before and after participation in the chorus program were significant only in overall problematic behaviors and excessive behavior. This indicates that the program was effective in improving problematic behaviors, particularly for excessive behavior. Fourth, the differences before and after participation in the chorus program in terms of ADHD were statistically significant for ADHD and its sub-variables of carelessness and hyperactivity impulsiveness. This indicates that there was an overall improvement in attention deficit/hyperactivity disorder. Therefore, the findings in this study showed that the chorus program was effective on enhancing character, social skills, problematic behaviors, and ADHD behaviors.

This study aims to identify the difference in the starting time of the dawn chorus of different species of birds and related environmental conditions. For this study, the bird songs were recorded every 2 hours a day starting from 2 hours before sunrise for a whole spring season (from April to June, 2014) in Korea. The recorded sounds were analyzed to find the starting time of each species' song by sonogram pattern using a sound analyzing program (Adobe Audition CC). To analyze the relationship between the environmental conditions and the time of the birdsong of each species, we collected the data of environmental conditions: daily precipitation, Julian date, time of sunrise and moonrise, temperature data and twilight time from the Korea Meteorological Office. As a result of this study, it was found that there are several statistical correlation between the starting time of the birdsong and environmental conditions (every environmental condition except daily precipitation and time of moonrise). Also, the difference of the starting time among each species were identified. The species were divided into 3 groups (early, mid and late) by their wake-up time. Ring-necked pheasant and yellow-throated bunting were categorized as 'Early' group and all woodpeckers were categorized as'Late' group. This study is significant as it first presented a classification of wild birds in Korea by the starting time of their dawn chorus. However, further studies are required to identify why each species to do their dawn singing at different times.

We developed an electronic music glove (EMG) system that could play musical scores in real time processing. The EMG system interfaces with the signal coming from the controller to the sound card in the computer. The computer, according to the status of the finger and foot switches, generates the signals to the speaker systems using the application C++ program by making use of MIDI message. The EMG systems can control up to several octave notes and duration of sound, and several musical performance expressions such as chorus, reverberation, rhythm, and volume. Finally, our EMG could play the performance of simple music depending on the choice of any kind of musical instruments in the sound card in computer systems.

We developed a electronic music glove (BMG) system that plays musical scores in real time processing. The EMG system interfaces with the signal coming from the controller to the sound card in the computer, The computer, according to the status of the fingers and foot switches, generates the sound signals and sends them to the speaker systems through the application C++ program and MIDI message. The EMG systems control the velocity and duration of sound and several musical performance expressions such as chorus, reverberation, rhythm, and volume. Finally, we implemented the digital drum set using: the EMG system as example.

Multimedia materials were developed to creative children's songs to elementary schoolers so as to improve favorable personality. To this end, we selected elementary school students to select appropriate songs for the cultivation of humanity, and produced multimedia including various image materials such as animation, documentary, chorus, dance performances, and interviews. Above all, we have created a teaching - learning process and presented the program so that teachers can easily guide students to agitation. As a result, the change of personality of elementary school students was positively shown through sway broadcasting, and I tried to give practical examples of practical application for cultivation of creativity and personality that should be emphasized at elementary school.

This study was conducted with a randomized control group pretest-posttest study design to investigate the effects of a combined arts education program combining choral and respiratory training on the respiratory function, stress, and quality of life of university students. Twenty-five university students were randomly assigned to the experimental group (n=13) who participated in the combined arts education program and the control group (n=12) who participated in the general arts education program. As a result, there was a significant difference in the lung capacity, respiratory strength, stress and quality of life scale before and after the experiment in the experimental group (p<0.05). In addition, the results of the rest of the tests showed significant differences (p<0.05), except for the result FEV1. Through the results of this study, the combined art education program that combines chorus and breathing training will be beneficial as a program to improve stress reduction, breathing function and quality of life of university students.
