The increase in the number of music files in smart phone and MP3 player makes it difficult to find the music files which people want. So, Query-by-Singing/Humming (QbSH) systems have been developed to retrieve music from a user's humming or singing without having to know detailed information about the title or singer of song. Most previous researches on QbSH have been conducted using musical instrument digital interface (MIDI) files as reference songs. However, the production of MIDI files is a time-consuming process. In addition, more and more music files are newly published with the development of music market. Consequently, the method of using the more common MPEG-1 audio layer 3 (MP3) files for reference songs is considered as an alternative. However, there is little previous research on QbSH with MP3 files because an MP3 file has a different waveform due to background music and multiple (polyphonic) melodies compared to the humming/singing query. To overcome these problems, we propose a new QbSH method using MP3 files on mobile device. This research is novel in four ways. First, this is the first research on QbSH using MP3 files as reference songs. Second, the start and end positions on the MP3 file to be matched are estimated by using multi-layered perceptron (MLP) prior to performing the matching with humming/singing query file. Third, for more accurate results, four MLPs are used, which produce the start and end positions for dynamic time warping (DTW) matching algorithm, and those for chroma-based DTW algorithm, respectively. Fourth, two matching scores by the DTW and chroma-based DTW algorithms are combined by using PRODUCT rule, through which a higher matching accuracy is obtained. Experimental results with AFA MP3 database show that the accuracy (Top 1 accuracy of 98%, with an MRR of 0.989) of the proposed method is much higher than that of other methods. We also showed the effectiveness of the proposed system on consumer mobile device.

This study was attempted to seek the garden enjoyment of the Yang Un-geo etc., in the head house(宗宅) of Namwonyang's family and Jongho in Sunchang Gumiri through literature and field research. Admirers of Jongho were "six old Taoist hermit", including Cholo(楚老) Yang Un-geo(楊雲擧, 1613-1672) and Yangjindang Haman-ri, the author of Jongho-palgyeong, who was very close friends of Yang, as well as his son-in-law or out-law. Jonghojeong Pavilion, overland rock and nearby Takyeongjeong, which were built around a stone island shaped like a helmet, and a pool along the river, are known as 'Imcheonwonrim(林泉園林)' as the center of the custom that was conducted based on head house, which is up to 2km away from Jongho. Jongho-palgyeong is found to share the characteristics of Jeongja Palgyeong, which is based on Jonghoam, overland and Takyeongjeong, and the characteristics of the town's township of Namwonyang, Gumi-ri. The number of rock letters identified by the Mansutan members is a total of nine points, which clearly indicates that the scene was a scene where the custom of call to create poetry·fishing·playing musical instruments and drinking, as well as the scenery and landscape structure of the Jongho Palgyeong. Jongho Palgyeong, its customs and surrounding rock writing are highly suggestive and valid cultural views to remind or direct the old landscape of Mansutan Jongho and suggest to modern traditional landscapes as well as the "Noblesse oblige landscape enjoyment case."
The purpose of this study was to assess musically gifted students'needs in order to develop the gifted curriculum in music. The survey was carried out with 103 musically gifted students who are being educated in institutes for the gifted. The survey asked the needs about components of the gifted curriculum in music: the educational objectives, contents, teaching strategies, evaluation as well as educational environment influencing on the curriculum. As for the objectives, the result showed the highest needs was the ability to communicate with audience by expressing one's feeling. For the high school students, a large number items had significant differences between the necessary level and the current level. As for the contents, the highest needs were the class piano, second instrument, and the experience of the musical field. High school students needed the second instrument more than middle school students did. As for the teaching strategies, the highest needs were the autonomous choice by learners, the instruction pursuing learners' interests, and the field work. As for the evaluation, the highest needs were the peer evaluation and the evaluation on the collaborative performance or team work. As for the educational environment, the gifted in music strongly needed spaces to practice instruments. Additionally, high school students needed a space to perform like a concert hall. Thus the gifted curriculum in music must be thoroughly developed based on the result above.

This study assesses the necessity of popular music instructor training, and promotes the establishment of popular music educational institutions and certification related to applied music education. Popular music has profound influence in popular culture, and is gradually diversifying. However, successful singers predominantly remain mostly boy/girl performance groups lacking musical skills. This study posits the cause of this problem is the absence of popular music instructor training systems, and suggests solutions. Currently, Korea's popular music lacks a public education system that teaches students effectively. Also, popular music is acknowledged as field-oriented, and isn't recognized for its academic value. Lastly, the lack of professional instructor training system in higher educational institutions creates challenges in fostering effective teachers. Solutions to these problems include establishing dedicated educational institutions and establishing certification programs. Implementing these solutions will provide significant positive effects in developing globalization for the currently stagnant K-pop industry. In addition, these solutions would contribute to the stabilization of the popular music industry, enhancing the image, and developing the popular music industry in general. In conclusion, this study promotes the popular music industry development by influencing and promoting awareness of music professionals, not just applied music students.
Objective: This study composed a melody program through handbells, and applied it to the mixed-age edu-care children. Methods: This study implemented a handbell melody program suitable for children's interest and development characteristics, based on Nuri Curriculum, to 15 mixed-aged edu-care children aged 3 to 4 at C Kindergarten located in Seoul for 12 weeks (once a week) from October 2015. Results: The program consisted of the origin of handbell, promises to keep in playing the handbell, partial literary introduction, and musical note activities using teaching aids or games in an integrated way with other areas. Through the program, dynamic class could be carried out with mutual leading participation of a teacher and children. Consequently, children aged 3 to 4 could easily encounter playing the handbell, being interested in playing, and showed cooperative spirit and society-friendly behaviors. The mixed age edu-care teacher felt pleasure and achievement of challenge by performing the class herself, which had depended upon extracurricular activities. Conclusion/Implications: A further study as action research for edu-care teachers, focused on change of edu-care teachers themselves, is proposed.
The guide line of the SFRC mix design was not established, and the convenience of the practical application on the spot is not so good. In this paper, hence, the program which is optimized to result the mix proportion by the flexural strength and toughness, was developed to apply to SFRC on the practical spot. This program could minimize the number of trial mixes and get an economical and appropriate mixture. In addition, the theoretical background on which the program is based, will be the basis of the embodied method to mixing SFRC. Additionally, new algorithm, in this paper, was used to develop the mix proportioning program of SFRC. The new algorithm is the Harmony Search which is the heuristic method mimicking the improvisation of music players, Musical performances seek a best state determined by aesthetic estimation, as the optimization algorithms seek a best state determined by objected function value. And, it was developed the program about single fiber reinforced concrete, beside to the hybrid fiber reinforced concrete that two kinds of steel fibers, which have the different geometry, was reinforced. This will be able to keep the world trend to study, hence, offers the basis of the next research about hybrid fiber reinforced concrete.
The purpose of this study was to extract and validate the educational goals and the subjects for developing a music gifted curriculum. Based on literature review and analysis of music gifted curricula in foreign countries, 19 educational goals and 18 subjects were derived from literature review and analysis of music gifted curricula in foreign countries. To validate the educational goals and the subjects, delphi survey was carried out twice with 26 expert panelists in the field of music, music education and music gifted education. Delphi survey was analyzed using the mean, content validity ratio, and the degree of consensus. The final set of educational goals for music gifted education included 6 skills related goals, 4 creative expression related goals, 4 knowledge related goals, and 2 attitude related goals. The final set of subjects included 4 major-specific subjects, 5 foundational subjects, 4 theory-related subjects, 3 integration and social participation related subjects. The results of this study can be used as baseline data to develop a music gifted curriculum by providing ideas for deciding what to teach and why to teach in music gifted education.

Harmony search (HS) is a recently developed metaheuristic optimization algorithm. HS is inspired by the process of musical improvisation and repeatedly searches for the optimal solution using three operations: random selection, memory recall (or harmony memory consideration), and pitch adjustment. HS has been applied by many researchers in various fields. The increasing complexity of real-world optimization problems has created enormous challenges for the current technique, and improved techniques of optimization algorithms and HS are required. We propose an improved clustering harmony search (ICHS) that uses a clustering technique to group solutions in harmony memory based on their objective function values. The proposed ICHS performs modified harmony memory consideration in which decision variables of solutions in a high-ranked cluster have higher probability of being selected than those in a low-ranked cluster. The ICHS is demonstrated in various optimization problems, including mathematical benchmark functions and water distribution system pipe design problems. The results show that the proposed ICHS outperforms other improved versions of HS.
The purpose of this study was to determine the effectiveness the Song Psychotherapy Program in decreasing test anxiety in adolescent students. For this study, twelve sessions were conducted in five stages for four 14-year-old middle school students at D Middle School on Daejeon. To measure the effects of the Song Psychotherapy Program, the researcher compared the results of Test Anxiety Inventory of Korea (TAI-K) before and after the program. The researcher also analyzed the contents of the participants' verbal responses and answers to repeated questionnaires to find out what participants experienced in Song Psychotherapy. The results of this study were as follows. First, a comparison of test anxiety scores prior to and following the program showed an average decrease from 91.75 to 60.5. Second, the subjects reported a positive musical experience in the program. The results of the research as described above show that the Song Psychotherapy Programis effective in decreasing test anxiety levels and general examination stress in adolescent students.
Purpose: This study was to observe the effects of music therapy on the cognitive function, behavior, and emotions of elderly dementia patients, and to seek musical mediation for them. This study was conducted with patients in the Dementia Sanitarium in C City from March 13 to April 17. Method: The design of research was a nonequivalent control group non-synchronized design and the subjects were 25 patients-15 of whom were in the experimental group with 10 in the control group. The music therapy consisted of favorite music listening in the morning, favorite music group singing activity after lunch, and relaxing music listening after dinner. The schedule was followed 6 days a week for 2 weeks for a total of thirty-six session. The effect of music therapy was measured by MMSE-K and the behavior and emotion measuring equipment which had been derived by the researcher. The verification of the effects is that the score of cognitive function, behavior, and emotions of the experimental and the control group which were measured after the therapy had been applied was analyzed by descriptive statistics and t - test using SPSS WIN program. Result: 1) The degree of cognitive function of the experimental group which was received the music therapy is $11.53{\pm}5.37$ which is a little higher than the control group which is $11.20{\pm}6.32$, but it is not significant statistically (t= .14, p= .887). The first hypothesis which had assumed the recepients would have had a higher cognitive function level than the other was rejected. 2) Behavior score of the experimental group that received the music therapy is $68.90{\pm}7.86$ which is higher than the control group which is $66.40{\pm}11.13$, but it is not significant statistically(t= .61, p= .548). The second hypothesis which had assumed the recepients would have had a higher behavior level than the other was rejected. 3) Emotions score of the experimental group that received the music therapy is $42.13{\pm}5.04$ which is higher than the control group which is $35.20{\pm}6.12$, and it is significant statistically(t=3..09, p= .009). The third hypothesis which assumed the recepients would have had a higher emotion level was supported. Conclusion: music therapy which is composed of listening to music and group singing activity is an effective strategy for improvement of the emotions of the dementia elderly. But, the effect of music therapy on the cognitive function and behavior of elderly dementia patients is not significant statistically.
