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.

This study aims to develop Korean film music by using Korean traditional music with proper technique. As of 2019, current Korean film music is mostly modeled after Western music. The usage of traditional music instruments is significantly lower than the usage of western instruments and is merely used in Korean historical movies as embedded music. This supports the many views that Korean traditional music seems too difficult to appeal to the general audience in these modern times. Furthermore, there aren't any such cases to apply traditional music techniques to western instruments whereas there have been many occasions where traditional music instruments imitate western instruments with its tones. The suspected reason for this is due to the lack of proper understanding and techniques of traditional music that Korean film composers have utilized, and its limited exposure in popular music. However, traditions are special and unique way to represent the history, culture, lifestyle and characteristic of countries. Therefore, it is our duty to protect our own traditions. As both a Korean, and as a musician, new film music is needed which uses traditional music instruments and its techniques. When film composers create music with better understanding of Korean traditional music, this unique music will be able to transcend borders and spread throughout the world.

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.

The purpose of this study was to examine the effects of Korean traditional music education for young children on the development of musical attitude and rhythmic sense of young children. The subjects were 42 four or five-year-old children enrolled in two classes of a public kindergarten. Half were in the experimental and half were in the control group. Instruments were "Music Interest Test for Young Children" (Kim, 2000), "Musical Attitude Rating Scale for Young Children" (Ahn & Han, 1999) and "Primary Measures of Music Audiation" (Gordon, 1986). The procedure included pre-test, treatments and post-test paradigm. Experimental group had Korean traditional music activities three times per week, including listening, appreciation, singing, playing traditional instruments and creative movement. The control group was merely provided with materials related to the Korean traditional music. Data was analyzed by t-test. Results indicated significant differences in music attitude and rhythmic sense between the experimental group and the control group.

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
