The purposes of this study were to demonstrate whether a Physical Rhythm Education Program can alter children's rhythm perception and rhythm expression. To solve the questions posed by this study, 60 5-year-olds and 60 6-year-olds (a total of 120 children) from one child-care center in Kyunggi-province were selected. An experimental group participated in the Physical Rhythm Program which was carried out 10 times over the course of 4 weeks. The results indicated that the Physical Rhythm Program positively improved the children's rhythm perception and rhythm expression. In particular, the Physical Rhythm Program was more effective in producing effects upon six-year-olds' rhythm perception and rhythm expression (verbal, instrumental and physical expression) than five-year-olds' rhythm expression (instrumental and physical expression).

This paper is to develop an integrate curriculum of rhythm education activity program and to find the possibility of applying the program into actual music education field for kindergarten children. The outlook of this study is to develope a program integrating the elements of movement, language and rhythm to apply the program to 5 year old children for 6 weeks through 12 sessions, and to observe and analyze their level of rhythm creativity and rhythm reading ability.The analysis of the field observation data and recording data showed that the children achieved natural and better understanding of rhythm. Seen from the perspective of rhythm creation activity, while the integration of the elements of movement and rhythm influenced directly to enhance the level of understanding rhythm and the integration of the elements of language, rhythm helped indirectly to have better understanding rhythm through connecting the notions of rhythm and movements. However, when only rhythm and movements were combined, children tended to misunderstand the relative durations of ♩ and ♪ just as different tempos not as 2:1 duration relativity. And ♫ was too misunderstand as ♬ due to different durations of korean words when only rhythm and language were combined. To overcome the limit of understanding, all of the three elements; rhythm and movements and language should be integrated and constant auditory experiences are recommended.

Circadian rhythms in subjective alertness, mood, and performance can be classified as psychological rhythm, compared with physiological rhythm such as body temperature and hormonal change. While in normal condition entrained by 24hr zeitgeber, subjective alertness would reach its maximum value around midday, subjective alertness would parallel body temperature rhythm with its peak at evening in non-entrained, free-running state. With desynchronization technique, subjective alertness rhythm is thought to be controlled by both temperature and sleep-wake rhythm oscillator. Circadian performance rhythms depend on the kind of task tested. It shows parallelism with body temperature rhythm when subjects are tested with simple, repetitive task. But when tested with tasks requiring complex verbal reasoning or immediate memory, subjects would perform them best at early morning, with performance decreasing as time of day advances. The desynchronization technique shows that circadian performance rhythm of simple, repetitive task is dependent on temperature oscillator but circadian performance rhythm of complex verbal reasoning is influenced by both temperature and sleep-wake rhythm oscillator or another independent oscillator. It would be worthwhile to compare psychological rhythm with hormonal change such as cortisol and melatonin. And more simple and time-saving method than desynchronization technique may facilitate the study of the mechanism underlying psychological rhythm.

본 논문에서는 먼저 심전도 진단을 위한 처리 과정별 관련 연구내용을 살펴본 후 심전도 신호의 리듬 특징을 이용하여 부정맥을 검출 및 분류하는 방법을 제안한다. 특징 추출에서는 리듬 구간에 대하여 동일성 및 규칙성 등의 리듬 및 심박 분포에 관련되는 특징을 추출하게 되며, 리듬 분류에서는 리듬 구간의 특징에 대하여 미리 구축된 규칙 베이스를 이용하여 리듬 유형을 분류하게 된다. MIT-BIH 부정맥 데이터베이스의 모든 리듬 유형에 대한 실험을 통하여 정상 리듬 규칙만으로도 100% 부정맥 검출 성능을 보였으며, 부정맥 리듬 규칙으로는 유형 분류 적용 가능성을 확인하였다.

Historically, rhythm has played a key role not only in musical composition, but also in architectural design. In 1893, architectural theorist and art scholar August Schmarsow, in "The Essence of Architectural Creation," created a new definition of architecture as space-creation and characterized rhythm as a design principle. However, this new idea was confronted by Heinrich Wölfflin. While Schmarsow's theory represents a dynamic world-view based on anthropomorphism, the architectural theory of Wölfflin is based on the notion of harmony, displaying a kind of conservative stasis. These two main streams have greatly influenced the development of modern architecture. The concept of space has prevailed in the discourse of modern architecture, but the principle of rhythm has seldom received any positive recognition. This article introduces and develops the concept of rhythm and disputes whether Behrens and Frankl in particular, two who dispute Schmarsow's theories, have used the concept of rhythm in terms of space. I conclude that they could not overcome the notion of the physical-the body-, thus their use of the term rhythm is incongruous with the notion of space. The idea of rhythm in architectural creation remains an up and coming idea.

The purpose of the current study is to investigate the realization of speech rhythm in English as spoken by Korean learners of English. The study particularly aims to examine the rhythm metrics of English read speech by learners who speak Busan or the South Kyungsang dialect of Korean. Twenty-four learners whose L1 is Busan Korean and eight native speakers of English read a passage wherein five sentences were segmented and labeled as vocalic and intervocalic intervals. Various rhythm metrics such as %V, Varcos, and Pairwise Variability Indexes (PVIs) were calculated. The results show that Korean learners read English sentences with significantly more vocalic and consonantal intervals at a slower speech rate than native English speakers. The analyses of rhythm metrics revealed that when the speech rate was not normalized, Korean learners' English showed more variability in the length of consonantal and vocalic intervals. However, speech-rate-normalized rhythm metrics for vocalic intervals indicated that Korean learners transferred their L1 rhythmic structures (a syllable-timed language) into their L2 speech (a stress-timed language). Overall, the results suggest that Korean learners' English reflects the rhythmic characteristics of their L1. The effect of the learners' L1 dialect on the realization of L2 speech rhythm is also speculated.

Developing Magnetoencephalography (MEG) based on Superconducting Quantum Interference Device (SQUID) facilitates to observe the human brain functions in non-invasively and high temporal and high spatial resolution. By using this MEG, we studied alpha rhythm (8-13 Hz) that is one of the most predominant spontaneous rhythm in human brain. The 8-13 Hz rhythm is observed in several sensory region in the brain. In visual related region of occipital, we call to alpha rhythm, and auditory related region of temporal call to tau rhythm, sensorimotor related region of parietal call to mu rhythm. These rhythms are decreased in task related region and increased in task irrelevant regions. This means that these rhythms play a pivotal role of inhibition in task irrelevant region. It may be helpful to attention to the task. In several literature about the alpha-band inhibition in multi-sensory modality experiment, they observed this effect in the occipital and somatosensory region. In this study, we hypothesized that we can also observe the alpha-band inhibition in the auditory cortex, mediated by the tau rhythm. Before that, we first investigated the existence of the alpha and tau rhythm in occipital and temporal region, respectively. To see these rhythms, we applied the visual and auditory stimulation, in turns, suppressed in task relevant regions, respectively.

Within the framework of prosodic phonology (or the theory of phonology-syntax connection), the rhythm unit is not regarded as a domain of phonological rules. But I argue in this paper that the rhythm unit functions as a domain of phonological rules in Korean. I discuss five phonological rules whose domain of application is the rhythm unit.

Purpose: The study compared the rest-activity rhythm and sleep pattern of elderly with young group. Methods: The subjects were 22 over than 65 years old and 23 under 65 years old. An actigraph, sleep diary, Pittsburgh Sleep Quality Index and Insomnia Severity Index scale were used as measurement tools for this study. The data were analyzed with $x^2$, Lamda test, t-test and correlation with SPSS 15.0 program. Results: The elderly had lower curve than the young group in rest-activity rhythm on each time zone. In particular, the elderly group had lower rest-activity rhythm curve of 8, 9, 14, 18, 19, 20, 21, 22 and 23 time zone than those of young group. Sleep pattern had statistical difference in the total sleep time, PSQI and insomnia. Total sleep time of elderly had lower score and PSQI and Insomnia had higher score than young group. Age had correlation with rest-activity rhythm, sleep efficiency, PSQI and insomnia. Conclusion: Rest-activity rhythm of the elderly showed an increase in activity in the early morning because of earlier get up than the young group and an decrease in activity in the afternoon because of taking a nap at this time. Elderly sleep was that total sleep time increased but sleep efficiency decreased and insomnia intensified. This sleep pattern was related to age and rest-activity rhythm.
