Purpose: We determined the recruitment pattern of lumbar elector spinalis, gluteus maxims, inner and outer hamstring muscle during trunk flexion and extension. Methods: Thirty healthy subjects(male; 15, female; 15) without low back pain and other problems in lower extremities participated in this study. To measure the recruitment pattern, the onset times of electromyographic activity of the muscles were recorded during trunk flexion and return(extension) to standing position. Results: The medial and lateral hamstring muscle was activated first, next elector spinalis, the last, gluteus maximus in trunk flexion. In trunk extension to standing position, the order of recruitment was similar to trunk flexion although the frequency is different. There were different between male and female in flexion and extension movement. Conclusion: The recruitment order of lumbar extensor and hip extensors in trunk flexion and extension will provide database in evaluation and intervention of lower back pain and lumbo.pelvic rhythm disorder.

This paper aims to investigate the internal structure of the pre-nuclear intonation pattern and to discuss the inventory and usage of the phrasal tone in Korean based on the acoustic analysis of 80 test sentences. CSL Model 4300 was used for recording and filing, and Multi-speech Model 3700 for analysis. It is shown that the pre-nuclear intonation pattern is composed of one or more phrasal tones, the intonation pattern of the rhythm nit. It is observed that the second phrasal tone begins with a higher pitch than the first one and that the phrasal tones following the second one begins with a lower pitch than the preceding phrasal tone unless a certain word is emphasized. In addition to Level, Rising, Falling, and Rise-Fall phrasal tones already established in Lee (1990, 1991, 1996), Pall-Rise and Rise-Fall-Rise phrasal tones are newly established in this paper. It is observed that Rising and Rise-Fall-Rise phrasal tones are most frequently used as the first phrasal tone of a pre-nuclear intonation pattern and the falling tone as the last phrasal tone, and that Fall-Rise and level tones appear most frequently in the middle of a pre-nuclear intonation pattern.

The purpose of this study was to find a system and a progression principle in orchestral piece based on the outcome after comparatively analyzing the orchestral operation technique in "Battle for The Glory" out of the background music in the animation "Dragon Quest IV" by Koichi Sugiyama(1931~), who is a leading runner of Japan's animation music, based on functional parts daccord & Instrumentation Pattern, Rhythm Pattern, Voicing Pattern, and harmonic ratio by progression section devised by the writer. As a result, first, five themes in this music have specific instrumentation pattern, respectively. In a passage that is shown exposition, reprise, and representation in theme, the unity was emphasized by maintaining the same instrumentation pattern. On the contrary to this, a passage of being suggested new theme is being used the exchange method and addition & subtraction in musical instrument in order to strengthen diversity. Second, the voicing pattern is forming the vertical contrasting relationship of "thinness-thickness" on the whole. However, the diversity is being intensified that is changed into the structure of "thickness-thinness" in the third theme and of "thinness-thickness" that has two melodies in the fourth theme. Third, the rhythm pattern is forming the vertical contrasting relationship of "big-small" on the whole. However, the fifth theme is being given diversity with being changed into the structure of "small-big." Fourth, the harmony by progression section from the horizontal perspective is shown to be high in the proportion of unity in the section of being repeated and represented the theme and to be high in the proportion of diversity in the section of being suggested new theme. In this study, the balanced orchestral operation technique through the operation technique, which was used in this work, is what extracts the relationship of diverse proportions in the horizontal progression section based on the technique of vertical perspective. In this aspect, this analytical study is desired to be positioned as a new paradigm in establishing a theoretical system and an educational method in orchestration.

Hopkins의 도약률(Sprung Rhythm)은 영어의 운율자질인 강세에 의한 엄격한 정형률을 고수하고 있다. 즉 약강 5보격이나 약강 6보격의 정형률을 지킨다고 Hopkins는 주장한다. 일반 독자나 운율비평가는 이를 인정한다. 문제는 시인의 음량(quantity) 기준에 의하여 강, 약 자리를 어떻게 충족시키고 있느냐 하는 점이다. 모든 비평가는 Hopkins의 음량 기준의 지나친 편의성과 임의성, 및 응통성?에 대하여 그의 음량 이론을 수용하려하지 않는다. 그러나 Kiparsky는 Hopkins의 설명에 따라 시인의 도약률을 분석하면 시인의 음량 이론이 이유 있음을 설명해 보인다. Kiparsky의 분석에서 문제점은 없는가? 만약 있다면 그것은 바로 Hopkins의 음량이론의 문제점이 될 것이다. 이 연구에서는 Hopkins의 편지 속의 설명은 실제로 독자의 낭송 속에서 어떻게 실현될 것인가 즉 '귀로 듣고 감상(ear and taste)'할 때 나타날 리듬형, 즉 낭송의 틀에 의한 분석을 시도하였다. 그것은 도약률이야 말로 읽히기 위한 것이며 '보는 시'가 아니라는 전제에서이다. 여기에서는 낭송에서 나타날 도약률의 음량과 장단, 즉 지속시간을 하나의 '낭송보(Textsetting for Sprung Rhythm)'에서 투사해 보고자 했다. 그 낭송보는 Hayes & Kan(1994)의 '어린이의 민속노래 보(Textsetting for Children's Folk Songs)'를 원용하였다. 약강 4,5,6보격, 강약 4,5,6보격의 일정한 강세 모습과 일정한 지속시간을 보여주는 도약률의 '낭송보'는 다음과 같다('약'자리와 '강'자리의 간격은 일정하게 보고 '강'의 돋들림은 격자로 더 높게 표시하였다). 이와 같은 낭송보는 독자, 즉 낭송자의 낭송 가능 범위를 그려 준다. 즉 약자리의 두개나 그 이상의 음절을 한꺼번에 낭송할 수 있음을 보여 준다. 그 음은 자연히 연음(slurring)이 되기 마련이다. 그러므로 이 연구는 다음과 같은 사실을 규명해 준다. 첫째, 어떤 시행도 규칙적인 박으로 낭송된다. 둘째, 음량은 박자에 의하여 좌우된다. 즉 강과 약자리의 일정한 지속시간의 범위 내에서는 몇 개의 음절도 낭송이 가능하다. 그것은 일정한 간격의 자리를 나타내는 격자로 결정된다. 따라서 모라(morae)의 개념보다도 박자의 개념으로 도약률은 낭송된다. 셋째, 모든 약자리와 강자리는 일정한 간격과 실제의 박(묵박도 포함)에 의하여 규칙적이다. 넷째, 외율음보는 격자의 길이내에서 낭송된다. 그러나 이 연구의 기본은 시인과 독자의 율형(Metrical Pattern)에 대한 의식과 의도(intention)가 전제된다. 이것은 이 연구의 문제임과 동시에 장점이다. 시율의 분석은 보는 율형이 아니라 읽고 낭송하는 율형으로 분석되어야 함을 보여 준 것이 이 연구의 기여이다.

Mobile digital devices are very familiar and useful devices in the daily life of modern people, and are used for various tasks such as communication, reading, writing, and playing media. As the use of mobile digital devices has become more prevalent, user time has also been increasing. In particular, the number of people who use digital devices before sleep is growing. The light pollution associated with these devices is classified into four categories: urban sky glow, glare, light trespass, and clutter. The pattern in which modern people use digital devices corresponds to light pollution caused by light trespass and clutter from light exposure to artificial light at night. The light pollution caused by digital devices can cause melatonin secretion suppression, delayed sleep onset, reduction of sleepiness before bedtime, and periodic rhythm and cognitive function disturbances. In addition, a study of children and adolescents showed there may be disturbances in the sleep-wake cycle and circadian rhythm, deterioration of sleep quality, and daytime fatigue due to light pollution caused by artificial light at night from mobile digital devices. A multi-faceted research effort is also necessary to investigate the healthy use of mobile digital devices based on research evidence and insights with an accurate evaluation of the influence of mobile digital devices as a form of light pollution.

The purpose of this paper is to find out the way of utilizing phrases of Chinese poetry in Manjeongje and its musical characteristics. To this end, the roles of phrases contained in the Pansori words were classified into five patterns: landscape description, strengthening of pleasant emotions, strengthening of sad emotions, wordplay, and combination of various poems. As a result of analysis, phrases quoted in sad mood part consist of slow rhythm of Jinyangjo and Jungmori, and sad melody of Gyemyun-gil and Jingyemyun tone; thus, both the rhythm and melody are expressed in accordance with the mood of poems. On the other hand, the melody in the landscape description parts, and the rhythm in the joyful feeling and wordplay parts showed the characteristics of determining the mood. In addition, when applying the analysis results to the perspective of Pansori composition, it is necessary to discover novel texts, apply to editorials, and study musical implementation suitable for the original mood in order to create more artistic Pansori.

We invesigated whether the circadian rhythms of plasma MHPG and HVA concentrations exist in 11 healthy young adults, and analyzed the patterns of their circadian rhythms. The results were as follows : 1) The change in the mean plasma MHPG concentrations analyzed by repeated measures ANOVA was not statistically significant. Five subjects showed significant circadian rhythms of plasma MHPG concentrations of each individual, and 4 of those had the acrophases between 17PM and 24PM. 2) The change in the mean plasma HVA concentrations analyzed by repeated measures ANOVA was not statistically significant. Six subjects showed significant circadian rhythms of plasma HVA concentrations of each individual, and 4 of those had the acrophases between 21PM and 6AM. In conclusion, the circadian rhythm pattern of plasma HVA concentrations in our result is consistent with the previous study. It was suggested that plasma MHPG and HVA concentrations should be measured more frequently, and the physical activities of subjects be controlled more strictly for the following study.

This paper aims to explore the rhythmic phenomena of standard Korean by an experimental phonetic method. A total of 16 informants taking part in this experiment were divided into four groups : old males(OM) and old females(OF) in their fifties and young males(YM) and young females(YF) in their twenties. The informants were asked to read speech data consisting of two rhythmic units, each of which began with a stressed syllable with a long wowel. Starting with the frame / 'ma:1 'ma:nta /, the first rhythmic unit was expanded up to five syllables in all while keeping the second rhythmic unit constant with a view to investigate the pattern of increase in the interstress time interval. The results of this study are as follows: 1. There is a considerable difference between yen and old generations with respect to the duration of interstress interval . The young generation tends to speak faster than the old generation. This observation is supported by difference in the interstress intervals as exhibited by OM(389.66), OF(473), YM(275.55), YF(285.83) in the test frame '말 많다' ['ma:1 'ma:nta]. 2. Young and old generations showed a different tendency in the increase rate of duration between mono-syllables and polysyllables. In other words, the rhythm of young generation shows the tendency of syllable-timed language whereas that of old generation clearly leans towards the stressed-timed language.

Purpose: Instead of a chaotic non circadian environmental approach, continuing regular day-night rhythm in neonatal nurseries may benefit the development of preterm infants. The purpose of this study was to define the effects of cycled lighting on circadian rhythms of premature infants. Methods: The experimental group included 15 preterm infants, and the control group, 15 premature infants in the NICU of a general hospital in Seoul. All infants were between 32 and 37 weeks' postconceptional age. The experimental group infants were provided with cycled lighting before discharge. The incubator or bassinet cover of the experimental group was off between 7 AM and 7 PM, and was covered between 7 PM and 7 AM. Results: There were significant differences in the NNNS score ($p$=.039), and some significant differences in the sleep-activity pattern between the experimental group and the control group, but distinct differences in sleep-activity patterns between the two groups could not be defined. Conclusion: The results of this study suggest that cycled lighting can be helpful in the neurobehavioral development of preterm infants. By modifying the NICU environment to provide a more developmentally supportive milieu, nursing professionals can better meet the infants' physiologic and neurobehavioral needs.
