This study finds aesthetic elements and examines their aesthetic sense focusing on the melody of the piri in the completed Jongmyojeryeak with various ideational backgrounds from the views different from the aesthetic sense of Jongmyojeryeak that has been conducted so far. Jongmyojeryeak is to hold a memorial service at the place where the godship of the line of kings and queens in Joseon is set. It is the crystal of Confucian memorial ritual and representative cultural heritage of ancestral ritual culture and is designated as No 1 of national chief, intangible cultural heritage in 1964. Also, on May 18th, 2001, it was registered first in Korea as 'Masterpieces of the Oral and Intangible Heritage of Humanity' designated by UNESCO and was recognized of its superiority. It is not only a representative cultural heritage of ancestral ritual culture having fate with Joseon Dynasty for a long period but also has been recognized as the essence of our music compiling the holistic beauty of artistic forms according to music, songs, and dance created by our ancestors. Also, it has as its background the traditional thoughts including the Confucian thought as well as Yeak thought, Yin-Yang School, Samjae thought (三才思想), and Palgoe thought (八卦思想). This Jongmyojeryeak internalizes landscape beauty, Yojang beauty, natural beauty, magnificent beauty, and harmonious beauty. Landscape beauty can be found in Huimun and Jeonpyehuimun. Yojang beauty is the figure that is only shown in Jeongdaeup. Natural beauty is the skilled performance technique shown in the melody of variations and is connected to natural creation. It is well shown in Huimun and Jeonpyehuimun. Magnificent beauty is well shown in the melody of Botaepyeong movement. And harmonious beauty is the harmonization of dischord in Jongmyojeryeak and is well shown in Jeongdaeup's Somu distinctively showing its aesthetic sense from the view of natural, harmonious beauty in its music.

According to a recent KOFICE survey, K-Pop's popularity factor is divided into visual and auditory elements, and the importance of hearing elements is found. Among the various types of singers, idol groups led K-Pop and Black Pink, which topped the list of favorite K-Pop singers in 2018, was selected as the study target. In addition, Twice's music, which is similar to Black Pink's period of activity, has been set as a comparative research scope. The common features in the music of the two groups are the chorus and rhythm structure implemented around melody and Harmony rhythm, and the frequency of use of Major and Minor is greatly different. Through this method and modal interchange, K-Pop from 2016 to 2018 is analyzed. Research shows that first, more than one mode is used as a main melody. When more than one mode is used, different lines in the same line will vary depending on the functional form of the song. Second, the rhythm of the melody expressed with vocals and instruments is repeated based on a two-bar pattern. Finally, when using less chord and slowly expressing the igneous rhythms, there is a way to omit or modify the third notes that determine chord characteristics. Through this study, we can see that the usage patterns of the mode and modal interchange are divided according to the major and minor.

This case study aimed to develop a therapeutic rap protocol based on narrative components for improving discourse skills of adolescents with mild intellectual disability (ID) and to explore its applicability. The protocol matched narrative elements (background, initiating event, internal response, attempts, and reaction) with rap components (verse, hook, and interjections), guiding participants to narrate their experiences in a connected discourse form. The protocol was also structured to gradually increase in difficulty, considering the developmental levels of adolescents with ID and it included steps for understanding discourse structures, applying narrative elements to content creation, and expanding narratives. Post-intervention analysis of the stories and rap lyrics created by participants to express their real-life experiences showed that participants increased the length of their stories and rap compositions, with notable improvements in rhythmicity and the inclusion of narrative elements. These findings suggest that, instead of constructing rap from random utterances, providing a structured framework reflecting discourse structure enhanced participants' understanding of event context and logical connections. Furthermore, the various elements and rhythmic features of rap can strengthen motivation and organization in discourse. This study highlights the therapeutic potential of rap in addressing the unique developmental needs of adolescents with mild ID, thereby diversifying and systematizing music therapy interventions for this population.

This paper presents an application of heuristic harmony search (HS) optimization algorithm for the identification of linear continuous time-delay system from step response. Identification model is first-order plus dead time (FOPDT), which describes a linear monotonic process quite well in most chemical processes and HAVC process and is often sufficient for PID controller tuning. This recently developed HS algorithm is conceptualized using the musical process of searching for a perfect state of harmony. It uses a stochastic random search instead of a gradient search so that derivative information is unnecessary. The effectiveness of the identification method has been demonstrated through a number of simulation examples.

자동차 오디오는 차량의 상품성에 큰 영향을 미치고 있다. 고급 차량일수륵 또한 젊은 층일수록 차량 구매시 선택의 기준이 되기도 한다 그러나 자동차 오디오는 크게 두가지 면에서 가정용 오디오와 차이가 있다. 첫번째는 청취공간이 매우 헙소하다는 것이고 둘째로는 주행시 차량소음이 차 실내로 유입되어 오디오 음질에 영향을 미친다. 차 실내는 즘은 공간 음향폭성으로 인한 음향 dip 현상이 발생하며 이는 오디오 음질의 왜곡을 가져오므로 이를 개선하기 위해서는 라우드스피커 최적배치 뿐 아니라 주행소음에 대한 시험 및 분석을 하여 오디오 음질에 영향을 주는 주파수 밴드를 파악하여야 한다 본 논문에서는 오디오 음에 차량소음이 섞인 경우에 대하여 차량의 라우드스피커 위치는 변경하지 않고 라우드스피커의 주파수 밴드별 출력을 디지털필터를 이용하여 수정하는 방법으로 음질 개선을 제안하였다. 디지털 필터의 보정치는 차량 주행소음 특성과 차 실내 음향특성을 고려하였다. 차량소음을 섞은 주파수 옥타브 밴드 분석법을 이용한 객관적인 분석과 감성적 분석법인 NCB곡선으로 차량소음을 분식하여 디지털 필터 보정치를 구하는데 사용하였다. 제안한 9가지 디지털 필터를 이용하여 차량소음과 음악을 합성하였고 이중에서 좋은 음질에 대한 판정을 하기 위해 Scheffe가 제안한 7점 주관 평가법을 사용하여 64명이 내린 주관평가를 수행하였다.

우리나라의 교회는 점점 신도수가 늘어나면서 점차 대형화되어가고 있으며 많은 첨단 설비를 갖추고자 하는 교회도 적지 않다. 하지만, 교회설계에 있어서, 대체로 그 형태와 규모만 중요시될 뿐, 그 기능에 적합한 건축물을 짓는데 소홀해 왔던 것이 사실이다. 교회의 예배공간에서 이루어지는 음향적인 매개체는 찬양과 설교인데, 이 두가지의 물리적 특성이 다르기 때문에 교회건축에 있어 실내음향은 어려운 과제라고 할 수 있다. 즉, 성가는 긴 잔향시간과 음의 따뜻함(Warmth)과 친밀감(Intimacy)등이 중시되는 반면, 설교는 소리의 명료도, 요해도(intelligibility) 등이 중시되는 등 그 음향적인 특성이 달라, 각기 다른 음환경을 요구하기 때문에 강당이나 음악당보다 교회음향이 건축적으로 난점이 있다고 하겠다. 본 연구는 최근에 시뮬레이션을 통해 음향설계를 실시한 규모가 각기 다른 예배실의 제원과 음향성능을 조사하고 그 특성을 비교, 분석하여 일반적인 음향성능을 개선하기 위한 방안을 모색하여 교회 음향설계단계에 자료를 제공하고자 한다. 이를 위하여 예배실의 규모에 따라 5개의 교회를 선정하였으며 시뮬레이션을 통해 얻어낸 각 교회의 성가시, 설교시 실내음향인자값(SPL, RT, C80, RASTI)과 마감재료 등을 조사하고, 비교하였다. 대체로 규모가 큰 교회에서 음압레벨이 작게 나타났고, 잔향시간도 실의 체적이 클수록 크게 나타났지만 마감재료와 형태에 따라 차이를 보였다. 또, 대형교회의 음향적 결함을 보완하기 위해서는 건축의 형태, 재료는 물론, 전기음향설비의 보강이 중요하다고 하겠다.

The purpose of this study is to analyze the changes in mathematical learning through applying STEAM education according to social needs for out-of-school youth. For this purpose, we developed a teaching and learning model and program for mathematics and music STEAM education, and we implemented and analyzed the changes of affective area and problem-solving strategies. The analysis results of characteristic in affective area are as follows: first, the activity-oriented class of mathematics and music STEAM education aroused interest in mathematics. Second, providing opportunities for mathematics and music STEAM education instilled a positive perception of the value of mathematics and STEAM education. Third, the autonomous communication-oriented learning environment of mathematics and music STEAM education improved confidence and motivation to learn in mathematics. The analysis results of the characteristic in problem-solving strategy are as follows: first, through the STEAM education with mathematics and music, a conceptual understanding of internally and externally dividing points was formed, and a given problem was expressed and solved in a formula. Second, the functional correspondence relationship was understood, and the given problem was described and solved with symbols associated with the function. The suggestions of the study are as follows: first, based on the teaching and learning model and results of this study, various STEAM education programs for out-of-school youth should be developed and expanded to foster future competencies and provide new changes for out-of-school youth. Second, it can be used for research on the development of teaching and learning materials for convergence elective subjects in the high school credit system by referring to the mathematics and music convergence STEAM program of this study. As the subjects and fields of STEAM education are diversified and organized, students in need of receiving educational opportunities will be reduced, and there will be a world where the name of out-of-school youth and alternative education will not be necessary. Therefore, it is expected that development of teaching and learning programs created by interest in education of out-of-school youth will be used as an innovative idea in school education to achieve a virtuous cycle.

This study is to analyze the current status of transmission and musical characteristics of Naeseo-deulilsori in Changwon, and the purpose of this study is to illuminate the value of deulilsori in Naeseo region, so that it can be continuously inherited. Naeseo-deulsori consists of the Mosimgi-sori, Nonmaegi-sori, and Chingchingi-sori. Mosimgi-sori, which is called when planting a seedling, is divided into 6 types according to the order and situation of work. ① rice planting sound, ② rice planting sound called in the morning, ③ rice planting sound called at lunch time, ④ rice planting sound called after lunch, ⑤ rice planting sound called when it is raining or cloudy, ⑥ rice planting sound called at sunset. Mosimgi-sori, which is called when planting a seedling, is based on Menali-tori, but partly influenced by Yugjabaegi-tori. However, it was typical Menali-tori in the slow The sound of rice planting in the nearby Haman region, but as the speed increased in the fast The sound of rice planting, the characteristics of Menali-tori faded and la↘mi perfect fourth descending frequently appeared. In the sound of rice planting in Goseong, both slow and fast sounds were strongly influenced by Yugjabaegi-tori. In the end, the sound of rice planting in the Naeseo region is less Yugjabaegi-tori than in the Goseong region and stronger than in Haman region. This combination of tori is a musical bargaining phenomenon that appears in the border region, and it can be said to be a geographical and regional characteristic of the Naeseo region. Nonmaegi-sori has the same sound as 'Sangsadeio' throughout the nearby Goseong and Haman regions. However, in Nonmaegi-sori in the Naeseo region, a strong Gyeong-tori tendency is found in the sound received. Looking at the flow of the melody of Nonmaegi-sori, it seems that the pitch has been changed by the intestines in recent years, and this modified melodic form has continued as it is. In order to guarantee locality, this part seems to need to be corrected in the future.

허밍에 의한 고정도의 오디오 정보 검색 시스템을 구현하기 위해서는 시스템 측에서 발생 가능한 문제점과 유저 측에서 발생 가능한 문제점을 함께 고려한 해결 기법이 요구된다. 유저 측에서는 허밍시 자신의 애매한 기억에 기인한 음표의 삽입이나 탈락과 같은 가창실수, 허밍 도중에 음정 및 박자의 불안정한 변화, 같은 곡을 노래 부를지라도 개인차에 의해 상이한 음정과 템포 등이 발생한다. 또한 시스템 측에서 발생 가능한 사항으로써, 비록 허밍질의가 완벽하더라도 입력 허밍 신호를 멜로디 매칭에 이용되는 정확한 특징량의 추출 및 음악 표기로의 변환이 어렵다는 점이다. 종래의 오디오 정보 검색 시스템에서는 이러한 문제점을 해결하기 위해 다양한 멜로디 표현법과 매칭 방법이 제안되고 있으나, 성능 면에서는 아직 만족할 만한 결과를 얻지 못하고 있다. 따라서 이러한 문제점들을 해결하기 위해서 본 논문에서는 허밍 멜로디의 효과적인 표현방법과 시스템 및 유저 측에서 발생 가능한 오류에 강건한 멜로디 매칭 방법을 제안한다.
