클래식 음악은 '작곡가가 쓴 그대로 연주해야 한다'란 엄격함이 존재했다. 그러나 다양한 개성과 사고를 중시하는 21세기 포스트모더니즘 시대에 들어서면서 전통 클래식 무대를 제외하곤 그 엄격함의 무게가 더 이상 유의미하지 않게 되었다. 클래식의 기품은 간직한 채 엄격한 규칙대신 대중음악의 친숙함을 접목시키며 크로스오버 된 오페라 아리아는 그 동안 어렵게만 느껴졌던 오페라 아리아가 대중들에게 한층 쉽게 다가가며 클래식의 대중화를 이끌어내는 큰 역할을 하게 되었다. 그럼에도 불구하고 클래식 음악을 크로스오버 음악으로 탈바꿈시키는 편곡기법에 관한 연구는 부족한 상황이다. 따라서 본 연구는 객관적 음악분석 방법인 화성, 리듬, 악기 편성 중심으로 기존 선행연구의 연구범위를 확대한 오페라에 대한 크로스오버적 편곡기법을 연구하였다. 분석결과, 원곡과 팝페라 버전은 리듬, 화성에는 유사성을 보이고 있으나 악기 편성에서는 차이점을 보이고 있다. 재즈 버전은 아프로큐반 리듬의 발라드 계열인 볼레로 리듬, 재즈 어쿠스틱 악기 중심의 구성, Tension을 많이 사용한 Voicing을 통해 클래식컬한 느낌을 없애고 재즈의 느낌으로 연출하여 원곡과의 차별을 보이고 있는 것이 특징이었다. 본 연구가 클래식컬 크로스오버 편곡기법 연구 자료로서 유용하게 쓰이길 바란다.

In order to know the characteristics of circadian rhythms in core temperature in tropical inhabitants, we measured rectal temperatures every 10 min for 24 hrs in 6 Vietnamese, 20 - 22 yrs (5 males and I females) under natural conditions. Average light intensity was 16000 lx. Ambient temperatures ranged from 33 to 36 oC. These data obtained were compared with those in Japanese setters and the Polish inhabitants. The participants were sitting mostly during wakefulness and lying in bed during sleep. The results obtained are summarized as follows: I) The average maximum value was 37.7 oC, which was significantly higher than in the Japanese and Polish as well. 2) The average minimum value was 36.4 oC, which was also lower. 3) A range of oscillation was 1.3 oC, which was clearly greater than in the people living in the temperate areas. The higher maximum value of core temperature, which was actively regulated under warm temperature, seemed of adaptive significance in order to reduce water consumption. A greater rage of oscillation in tropical Vietnamese people might have ecological significance for efficient acclimatization in the environment with strong light intensity and high ambient temperature, suggesting that the setpoint of core temperature could show a greater range of oscillation.

To determine the optimal rotational shift system, the effect of the direction of the rotational work shifting on the nocturnal rhythm of plasma melatonin were investigated in nursing students. Two groups of nine volunteers participated as experimental subjects, and two nursing students participated as a control group. The directions of the rotational work shift were as follows: CW(clockwise)-shift were rotated in the direction of day shift(3 days), evening shift(3 days), off duty(1 day) and night shift(5 days), and CCW(conuterclockwise)-shift were done in the reverse direction. Plasma melatonin concentrations was measured by radioimmunoassay. The results were as follows : The plasma melatonin levels were kept low at night and in the following morning in the CW night shift workers, whereas the level started to increase at 05 : 00 hr in two workers of four CCW shift workers. These result suggests that the shift rotation in the CW direction is more acceptable in terms of the adaptation of hormonal rhythms. These results indicate that the CCW rotation of shift work is somewhat better than CCW rotation for the adaptation to shift work on hormonal aspects in nurses.

Purpose: Breathing can be controlled either unconsciously or consciously. In Asian countries, various conscious breathing-control techniques have been practiced for many years to promote health and wellbeing. However, the exact mechanism underlying these techniques has not yet been established. The purpose of this study is to explore the physiological mechanism explaining how conscious breathing control could affect the autonomic nervous system, brain activity, and mental changes. Methods: The coupling phenomenon among breathing rhythm, heart rate variability, and brain waves was explored theoretically based on the research hypothesis and a review of the literature. Results: Respiratory sinus arrhythmia is a well-known phenomenon in which heart rate changes to become synchronized with breathing: inhalation increases heart rate and exhalation decreases it. HRV BFB training depends on conscious breathing control. During coherent sinusoidal heart rate changes, brain ${\alpha}$ waves could be enhanced. An increase in ${\alpha}$ waves was also found and the synchronicity between heart beat rhythm and brain wave became strengthened during meditation. Conclusion: In addition to the effect of emotion on breathing patterns, conscious breathing could change heart beat rhythms and brainwaves, and subsequently affect emotional status.

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.

The aims of this article is to examine that Daegeum Sanjo Rhythm (DSR) compare with Jinyang-jangdan and Jajinmori-jangdan on music therapy. Daegeum has the largest range of notes in wind instruments through Korean music. Jangdan is the essential element of rhythm in Korean music. Just as human body sound and resonant with their rhyme and meters, jangdan has its own rhythms of physical structures and sequence and repeat. Jinyang-jangdan, which is close to western minor code, expresses heartbreaking grief and great mourning feeling, so it makes one feel the catharsis through that rhythm. Jinyang-jangdan of daegeum music may be slow, but it can be sublimated into grim music for human. So, people overcome the sadness through grim music. On the other hand, jajinmori-jangdan gives charm and gaiety to people and to everything. So, it is exciting that it's often performed in festival and parade. Rhythmical music is a tool to improve the well-being of humanity and increase our life choices. Therefore, music therapy surely needs both influences of daegeum sanjo music regardless of the rhythm. Because, daegeum sanjo music is nature-friendly music of the rhythm.

The forms made by repeated arrangements of basic units defined as Simulakre are recomposed into organic, geometric or multi-functional forms by diverse combinations and arrangements and the space expanded by reiterated compositions will have the meaning of active space expansions representing speeds, rhythms or time by reiterations instead of a limited and fixed place shown by a work. The module design that can create new roles and functions of spaces that are variability and fluidity and that can be assembled and transformed into the shapes, sizes and functions desired by users will be analyzed applying the concepts of reiteration and expansion. The module designs emerging in 21th century are in diverse organic forms and geometric forms and their methods for expansion are also diversified. And instead of having a function, they have diverse functions such as storages, partitions, walls, curtains and soundproofing. The development of module designs are first to satisfy the diversified needs, individualities and desires to posses of modem people and second the development, finding and application of new materials. In the future spaces that will continuously develop and will be nomadic, the flexible and individualized module designs will become more diversified and will have their significances.

Many mammals in temperate zones are affected by the distinctive changes of the four seasons in these zones. Their reproductive status is active in the summer climate and inactive during severe winter weather. The golden hamster (Mesocricetus auratus) is seasonal breeding animal whose sexual activities are regulated by photoperoidism. The reproduction and metabolism are activated by long summer days (LD) and inhibited by short winter days (SD). After several months of SD, animals become refractory to this inhibitory photoperiod and spontaneously revert to LD-like physiology. The suprachiasmatic nuclei (SCN) house the primary circadian oscillator in mammals. Seasonal changes in the photic input to this structure control many annual physiological rhythms via SCN-regulated pineal melatonin secretion, which provides an internal endocrine signal representing photoperiod. The aim of this study was to assess the variation in the morphology of the testis in relation to the natural photoperiod in male golden hamsters. The hamsters were castrated at different weeks (2, 5, 8, and 15). The cell numbers of tubules with spermatogonia (SG), spermatocyte (SC), spermatids (ST), and spermatozoa (SZ) were recorded in each sample. The results showed that testicular regression of golden hamsters occurred in the SD-treated animals. The present investigation determines that the effects of the photoperiod on the reproduction of male golden hamsters. It was also found that the circadian period increases the rate of reproductive inhibition in animals exposed to inhibitory photoperiods.

A life-long anticoagulation for the prevention of ischemic cerebral events by thromboemboli has been conventionally introduced for the treatment of an atrial septal aneurysm. However, due to the recent decrease of the risks in the open heart surgery, the alternative therapeutic modality has been introduced for the prevention of complications of the anticoagulation. A 41-year old female with dizziness was admitted to our hospital. She was diagnosed a shaving atrial fibrillation and a cerebellar infarction, and an atrial septal aneurysm was detected by transesophagel echocardiography that was not detected by the transthoracic echocardiography. Surgery was approached to the right submammarial anterolateral thoracotomy. The atrial septal aneurysm was obliterated by a purse-string suture and plication. Surgial results were excellent with normal sinus rhythms and esthetically satisfying appearance.
