This paper proposes a MIDI- and audio-based music genre classification method for Korean traditional music. There are many traditional instruments in Korea, and most of the traditional songs played using the instruments have similar patterns and rhythms. Although music information processing such as music genre classification and audio melody extraction have been studied, most studies have focused on pop, jazz, rock, and other universal genres. There are few studies on Korean traditional music because of the lack of datasets. This paper analyzes raw audio and MIDI phrases in Korean traditional music, performed using Korean traditional musical instruments. The classified samples and MIDI, based on our classification system, will be used to construct a database or to implement our Kontakt-based instrument library. Thus, we can construct a management system for a Korean traditional music library using this classification system. Appropriate feature sets for raw audio and MIDI phrases are proposed and the classification results-based on machine learning algorithms such as support vector machine, multi-layer perception, decision tree, and random forest-are outlined in this paper.

이 연구의 목적은, 한국 전통 음악의 어법을 활용하여 영화 음악을 발전시키기 위함이다. 2019년 현재 한국 영화 음악은 대부분 서양 악기 기반으로 만들어진다. 전통 음악이 쓰이는 빈도수를 확인해 보면, 서양 악기 기반의 음악보다 철저히 적음을 알 수 있으며, 1980년대 이전까지 한국 영화에서 다양하게 쓰이던 전통 악기와 전통 음악조차, 이제는 사극에서 내재적 음악으로 사용되는 데에 그치고 있는 것이 현실이다. 그리하여 전통 음악은 대중적으로 다가가기에 어렵다고 보는 관점이 많아지고 있으며, 많은 창작 음악 중에서도 영화 음악에는 거의 등장하지 않는다. 더 나아가 전통 악기의 음색을 사용하여 서양 악기를 흉내 내는 경우는 많은 반면, 전통 선법이나 장단, 시김새 등 전통 어법을 양악기로 연주하는 경우는 극히 드물다. 이는 필히 영화 음악을 작곡하는 음악가들의 전통 음악 어법이나 선법에 대한 제대로 된 이해가 부족함이 있을 것이며, 요즘의 음악 흐름에 전통 음악이 없기에 굳이 시도하지 않는 것이라고 생각된다. 하지만'전통'은, 그 나라의 역사와 문화, 생활, 성격 등을 모두 아우르며 그 민족을 나타내는 고유하고 특수한 것이다. 현재 디즈니사 영화나 할리우드 영화 등 세계적으로 유명한 영화를 살펴보면, 각 나라의 민속 음악을 활용하여 다양한 색채를 나타내는 월드 뮤직 형식이 많이 등장함을 알 수 있다. 이는 민속적인 색깔을 드러냄으로써 그 나라의 문화를 알리는 데 크게 일조한다. 하지만 한국의 색깔을 드러내는 영화나 음악은 찾아볼 수 없음이 현실이다. 이에 필자는 전통을 지켜내고자 하는 한국인으로서, 그리고 음악가로서 영화 음악에서 전통 어법을 사용한 음악이 필요하다는 것을 제안하였다. 제안 근거로 세계적으로 나라의 문화를 알리는데 일조한 중국 음악계의 '뉴웨이브' 양식과, 전통 어법이 서양 악기 양식으로 융화된 '탄둔'의 '와호장룡' 영화 음악을 예로 살펴보고, 그 음악으로 인한 효과를 한국 전통 음악에 대입했을 때도 훌륭한 효과를 나타낼 수 있을 것임을 증명하였다. 그를 통하여 영화 음악 작곡가들이 전통 음악을 더 잘 이해하고 하나의 음악을 만들어 내었을 때, 한국인만이 할 수 있는 가치 있는 음악이 완성되어 한국을 넘어 세계로 뻗어져 나갈 수 있을 것이다. 또한, 4차 산업혁명을 살아가고 있는 현재 그리고 미래에 우리의 목소리를 더 낼 수 있을 것이라고 기대한다.

300mm F/4.0 telephotolens with diffractive hybrid lens was designed, and its optical performance was tested and compared with a traditional lens system. DOE(Diffractive Optical Element) reconstructs wavefronts using wave phenomena of light to focus the incident light onto the focal point and has negative Abbe number while a traditional lens uses geometrical phenomena of light and has positive Abbe number. Therefore, a diffractive hybrid lens containing both refractive and diffractive elements can remarkably correct chromatic aberration and spherical aberration of an optical system. We investigated and analyzed the optical properties of a diffractive hybrid lens for the visible spectrum, and we used a difractive hybrid lens to design and evaluate a 300mm F/4.0 telephotolens without the special LD(Low Dispersive) glass lens which is costly and difficult to manufacture. Most traditional telephotolenses use the special LD glass for chromatic aberration correcton. Optical performance tests such as resolution and characteristics of aberration of both lens systems using a diffractive hybrid lens and traditional lens were performed.

Objective: This study was performed to investigate the prevalence of musculoskeletal disorders of traditional Korean instrument player using a variety of traditional classical instruments: Gayageum, Geomungo, Ajaeng, Haegeum, Daegeum, Piri and Samul instruments. Background: A large percentage of instrument players have suffered from the musculoskeletal pain of each body parts. However, there is no research on the prevalence of musculoskeletal disorders of traditional Korean musical instrument players. Method: Through the focus group interview, a questionnaire to investigate musculoskeletal disorders was developed. The questionnaire consisted of four parts: demographic factors, performance factors, musculoskeletal disorders symptoms, musculoskeletal disorder experience. For the survey, 118 expert players participated. The data from the survey were analyzed by correlation analysis and chi-square analysis. Results: The symptoms of musculoskeletal disorders and the severe pain from musculoskeletal disorders were observed at neck, shoulder, back and knee. The musculoskeletal experience was statistically related to the factor of body height in Gayageum and Geomungo. In addition, the musculoskeletal experience in Geomungo was related to age and career. However, the musculoskeletal experience in Ajaeng and Haegeum was only related to the factor of hobby. The musculoskeletal experience in Daegeum and Piri was related to stretching. In addition, there was a statistical significance between the musculoskeletal experience and sex in Daegum. In Samul instruments, the statistical significance was observed at age, BMI, career and stretching. Conclusion: The symptoms of playing-related musculoskeletal disorders of traditional Korean musical players were prevalently observed at neck, shoulder, back and knee. In addition, these symptoms were related to the various demographic factors such as age, body height, BMI, career, sex, hobby and stretching. Application: The results of this study can be used as the preliminary data for preventing the musculoskeletal injuries of traditional Korean musical instrument players.

Most modern adults are overweight or obese. Health services are troubling to overcome the large number of individuals in need of weight loss. Music therapy is emerging as a new option. Among various music therapy methods, it studied various treatments through Korean traditional music, and it is thought that Korean traditional music is a good therapy for diet. The present review focused on find the most useful condition for weight control by using Korean traditional music. National Center for Korean Traditional Performing Arts measured the dB of Korean traditional music, In the next, listen to other dB's music while eating and compared energy intake, water intake, duration of meals, number of servings, number of bites, eating rate (bites per minute), and bite size (grams). As a result of the exhibits, differences in food intake were also found in the difference of dB. 60 dB of music showed a decrease in energy intake. It suggests that Korean traditional music belonging to 60 dB brings weight loss effect. As a result, the effect of weight loss is shown by use Korean traditional music. However, future studies should be performed to reduce the energy intake by increasing the exposure period to Korean traditional music
