From the viewpoint of that music melody has the similar features to time-series data, music melody is transformed to a time-series data with normalization and corrections and the similarity between melodies is defined as the Euclidean distance between the transformed time-series data. Then, based the similarity between melodies of a music object, melodies are clustered and the representative of each cluster is extracted as one of theme melodies for the music. To construct the theme melody index, a theme melody is represented as a point of the multidimensional metric space of M-tree. For retrieval of user's query melody, the query melody is also transformed into a time-series data by the same way of indexing phase. To retrieve the similar melodies to the query melody given by user from the theme melody index the range query search algorithm is used. By the implementation of the prototype system using the proposed theme melody index we show the effectiveness of the proposed methods.

This study aims to acoustically analyze Korean language characteristics and convert these findings into musical elements, providing foundational data for evidence-based music-language rehabilitation. We collected voice data from thirty men and thirty women aged 19-25, each providing six-syllable prosodic units composed of two accentual phrases, including both declarative and interrogative sentences. Analyzing this data with Praat, we extracted syllabic acoustic properties and conducted statistical analyses based on acoustic properties, sentence type, gender, and particle presence. Significant differences were found in syllable frequency and duration based on accentual phrases and prosodic units (p < .001), with interrogative showing higher frequencies and declaratives longer durations (p < .001). Female frequencies were significantly higher than males' (p < .001), with longer durations observed (p < .001). Particle syllables also showed significantly stronger intensities (p < .001). Finally, we presented melodies converted from these acoustic properties into musical scores based on pitch, duration, and accent. The insights from this analysis of six-syllable Korean sentences will guide further research on developing a system for melodizing large-scale Korean speech data, expected to be crucial in music-based language rehabilitation.

The purpose of this study was to examine the effects of rhythmic auditory stimulation (RAS) on gait parameters, with and without the presence of a melody, for adolescents with traumatic brain injury (TBI). Three adolescents with TBI received a total of ten individual RAS training sessions. At pre and posttest, spatiotemporal parameters including cadence, velocity and kinematic parameters were measured using the VICON 370 Motion Analysis System. The results showed no significant difference in gait velocity between the two conditions, thus the presence of the melody condition did not impact the outcome of RAS gait training. On the other hand, all participants showed improvement in gait function after RAS training. The cadence, velocity, stride length, and symmetry were increased and the stride time was reduced after training. The motion analysis demonstrated that the movement patterns of hip and knee joints improved, as they were more similar to normal gait, which indicates that the walkings tance became more stable. The research findings indicate that rhythm is the primary factor in mediating gait functions via RAS training. This study also supports that RAS training can effectively improve the gait function for adolescents with TBI.

The purpose of this research is to analyze Soon Chul Jung's children's songs, who is one of the four great children's songwriters in Korea along with Geuk Young Yoon, Nan Pa Hong and Tae Jun Park. Soon Chul Jung has contributed by actively participate into children's movement at Japanese colonial period through writing self-composed children's songs. Since children's songs are made for the age group without the sense of sound, children's songs necessitate 'easy to sing-along' melody writing process. Like so, when writing the melody that are easy to be sang along, utilization of development technique using a unit called motive can be the potent way. This method has an advantage of being sang more with ease if actively implemented, and can be done by utilizing the smallest unit of the melody called motive, especially by lightly transform and repeat the unit, consequently structuring the song altogether. To investigate and analyze this motive-based development technique of Soon Chul Jung's songs, 38 out of 40 written songs considered eligible for the research were confirmed and chosen from 'Soon Chul Jung's bibliography and choreography' and each songs were analyzed based on 17 different development techniques which were standardized in the textbook 'Melody in Songwriting' adopted as a textbook of the Berklee college of Music, and also compared these song-writing pipelines with other great songwriters' representatives mentioned above. As a result, it was almost linear that the song's pitch variation in combination with thinning or extension were used frequently and repeatedly, otherwise implicating melody duplication for more than 2 bars and motive repetition were not in his favor, while these methods were often used when writing children's songs. This finding could be viewed as a character of his songwriting.

With the popularity of digital music contents, querying and retrieving music contents efficiently from database has become essential. In this paper, we propose a Fast Melody Finder (FMF) that can retrieve melodies fast and efficiently from music database using frequently queried tunes. This scheme is based on the observation that users have a tendency to memorize and query a small number of melody segments, and indexing such segments enables fast retrieval. To handle those tunes, FMF transcribes all the acoustic and common music notational inputs into a specific string such as UDR and LSR. We have implemented a prototype system and showed on its performance through various experiments.

Shin Gwang-su (申光洙, 1712~1775), also known as Seokbuk (石北), is a well-known poet and author of the song poetry (詩唱) "Gwanseo-akbu (Poems of the Gwanseo Region, 關西樂府)" in the late Joseon Dynasty. "Gwanseo-akbu" was popular among the Joseon Dynasty musicians. This fact confirms that the tradition of adding a melody to Shin Gwang-su's "hansi (Korean poetry recorded in Chinese characters, 漢詩)" already existed in the Joseon Dynasty. It is also a proof that the hansi poem was used in songs. Besides Seokbuk, other literary figures in the Joseon Dynasty wrote and sang hansi. In that case, the place of communication for songs was a poet's personal study, or "sarangbang." But when, like the works by Seokbuk, poems were sung by musicians, they became available to the public to communicate through music. This study is one of the attempts to re-make Seokbuk Shin Gwang-su's poems and songs, once popular among the Joseon Dynasty people, into the contemporary music that can be performed on stage. By adding a certain melody to his poems, this study introduces a case of musical work and offers an opportunity to consider hansi as performance art. There is a number of hansi works by Shin Gwang-su, and each poem includes material which can help survey Shin Gwang-su's musical life. And, working on his hansi works makes it possible to narrate major events that took place in Shin's life. Thus, this study attempts to focus Shin Gwang-su's musical life and introduces methods and contents to stage his hansi poems as performance art.

The pre-evaluation of the current-collection performance is an important issue for high-speed railway vehicles. In this paper, using flexible multibody dynamic analysis techniques, a simulation model of the dynamic interaction between the catenary and pantograph is developed. In the analysis model, the pantograph is modeled as a rigid body, and the catenary wire is developed using the absolute nodal coordinate formulation, which can analyze large deformable parts effectively. Moreover, for the representation of the dynamic interaction between these parts, their relative motions are constrained by a sliding joint. Using this analysis model, the contact force and loss of contact can be calculated for a given vehicle speed. The results are evaluated by EN 50318, which is the international standard with regard to analysis model validation. This analysis model may contribute to the evaluation of high-speed railway vehicles that are under development.

Through Korean traditional opera (changgeuk) Medea, composer Hwang Ho-jun showed eclectic music idiom by 1) writing music (jakchang) on manuscript paper and score, 2) introducing the "song-through" format, 3) including various solo melodies, 4) maximizing the effect created by a singing narrator (dochang) with the chorus master and a mixed chorus, 5) seeking an interplay of tension and release by using both discord and chord, 6) achieving the effect of kil-bakkum, the Korean traditional method of modulation, through modulation and borrowed chord of Western music. In Medea, instrumentalists adopted suseong-banju (Korean traditional accompaniment) which does not spoil the voice of singers. Hwang adopted song for the way how singers express various hidden sides of play among song, aniri (narration) and balim (gesture) and introduced the Sung-through format in which the play is comprised entirely of song. In Medea, oral sounds expressing wail, lament, cheer, sneer and scream are often used and various solo melodies appear that fit for personalities of characters, clearly showing what bunchang (singers' singing songs divided according to characters) is all about. And discord and chord are effectively used according to the development and mood of play. Hwang also achieved successfully the effect of kil-bakkum by abandoning the traditional modulation method and boldly introducing modulation and borrowed chord of Western music.
