Objectives : Periodic limb movements during sleep (PLMS) may cause arousals that may lead to non-restorative sleep. PLMS is characterized by long sleep latency, sleep fragmentation, frequent stage shifts, and rarity of stages 3/4 NREM sleep on polysomnography. However, controversies have existed and it still remains to be elaborated whether PLMS actually causes insomnia, since normal persons happen to have PLMS. Clinically, it would be crucial to know factors which might disturb sleep in PLMS. We became interested in Coleman's theory(1980) that invariant periodic movements disturb patients' sleep less. Though, Coleman's study seems to have been confounded by including PLMS patients with various co-morbid sleep disorders. Therefore, we attempted to study in patients only with PLMS the effects of movement patterns on sleep architecture. Methods : In 27 patients diagnosed as having PLMS only with clinical interview and nocturnal polysomnography, we studied the relationship between the movement patterns such as mean duration and variability of periodic limb movement's interval and the sleep architecture variables. Results : The shorter and the more regular the limb movement intervals were, the fewer arousals followed. The movement intervals of the older patients were shorter and more regular than the younger patients. The probability of the accompanying arousal with each limb movement increased as the duration and variance of the movement intervals increased. It decreased as the age and the frequency of limb movements increased. Among these factors the most significant one was the mean duration of the movement intervals. In other words, the shorter the movement intervals were, the less disturbed sleep was. Conclusion : PLMS frequency increases with aging but the probability of the accompanying arousal with each movement decreases with aging. Sleep-disturbing effects of PLMS depends more on the duration and variability of movement intervals than the PLMS frequency.

The purpose of this study of which 10 University students in their twenties are the objects was to examine the causal differences of kinematic and electromyography during power walking and normal gait. We came to the following conclusions. 1) It took less time to stance phase, swing phase and whole gait time during power walking compared with normal gait. 2) During power walking, the step length and step length and lower limb length are longer than that of normal gait. 3) During power walking, ankle joint angle became more plantar flexed at LIC and RTO, knee joint angle become more flexed, so did hip joint angle at LIC and RTO. Besides during power walking the shoulder joint angle movement was bigger and elbow joint angle was more flexed as the trait of power walking. 4) During power walking, through out the phase the muscle activity of all muscle was higher expecially the muscle activity of Biceps brachii, gastrocnemius medialis, gastrocnemius lateralis, Soleus was higher. Therefore during power walking, one's scope of activity and muscle activity is relatively higher than those of normal gait, so power walking helps one strengthen muscular power and energy metabolism. This will be useful information for those who are interested in diet and well-being.

본 연구는 임팩트 시에 클럽페이스의 면을 3차원적으로 분석해 보고자 한다. 또한 숙련자와 초보자간에 차이를 비교, 분석하여 초보자의 퍼팅 스트로크 기술을 향상시키는 기초자료를 제공하는데도 그 목적이 있다. 이를 위하여 숙련된 골퍼 5명과 골프경험이 전혀 없는 학생 5명 등, 총 10명이 피험자로 연구에 참여하였다. 실험은 실내의 인조잔디에서 실시되었으며, 잔디에 지름 0.108 미터의 흘을 파서 실제 그린과 동일한 상황을 만들었다. 클럽페이스의 면을 정의하기 위하여 헤드부분의 toe, heel, 그리고 neck에 각각 지름 0.01 미터 의 마커를 부착하였으며, AG 456 비디오카메라(60Hz, 1/500s) 두 대를 이용하여 움직임을 기록하였다. 클럽페이스의 움직임을 3차원적으로 분석한 결과 다음과 같은 결론을 얻었다. 첫째, 클럽의 좌우 움직임에 영향을 주는 면의 움직임이 숙련자의 경우 평균 1도로 매우 작은 반면에 초보자들은 평균 6도 이상이었다. 둘째, 숙련자들은 클럽의 움직임보다 손의 움직임이 빨라서 볼을 낮게(클럽페이스를 닫은 상태로 임팩트) 보낼 수 있으나, 초보자들은 클럽보다 손의 움직임이 느려서 볼을 높게(클럽페이스를 열은 상태로 임팩트) 보낸다. 셋째, 클럽헤드의 입사와 반사각도 비는 전체적으로 1:3-4 이나, 임팩트 존에서의 비는 1:2 정도이다. 넷째, 숙련자의 수직벡터 방향은 초보자의 수직벡터 방향보다 퍼트 선 방향에서 볼 때 이탈각도가 작다. 퍼팅 스트로크는 볼과 클럽, 그리고 볼과 그린의 접촉에 따라서 결과가 나타나는 종목이다. 따라서 퍼터의 움직임도 중요하지만 볼의 움직임과 그린의 역할도 함께 연구가 병행되어야 한다.

Going up and down the stairs is a repeated task in the activities of daily living. These activities are needed during the recovery process with impaired lower limbs. This paper presents the difference of EEI (energy expenditure index) through the slope of stairs. Twenty-one normal young adults took a part in this study (11 males, 10 females). They stepped up and down the stairs which had two different slopes for 5 minutes. Resting heart rate, walking heart rate, and moving distance were recorded. EEI was calculated from the heart rate and moving speed which was calculated by the distance of movement. Data were analyzed by repeated two-way ANOVA with SAS program and the difference of EEI through the slope of stairs was not statistically significant (p=0.9971). The results show that EEI was not affected by the slope of stairs in normal people. But distance of movement (p=0.0067) and speed (p=0.0064) had a significant difference.

We have carried out laboratory measurements of P-wave velocity and deformation strain during $CO_2$ injection into a porous sandstone sample, in dry and water-saturated conditions. The rock sample was cylindrical, with the axis normal to the bedding plane, and fluid injection was performed from one end. Using a piezoelectric transducer array system, we mapped fluid movement during injection of distilled water into dry sandstone, and of gaseous, liquid, and supercritical $CO_2$ into a water-saturated sample. The velocity changes caused by water injection ranged from $5.61\;to\;7.52\%$. The velocity changes caused by $CO_2$ injection are typically about $-6\%$, and about $-10\%$ for injection of supercritical $CO_2$, Such changes in velocity show that the seismic method may be useful in mapping $CO_2$ movement in the subsurface. Strain normal to the bedding plane was greater than strain parallel to the bedding plane during $CO_2$ injection; injection of supercritical $CO_2$ showed a particularly strong effect. Strain changes suggest the possibility of monitoring rock mass deformation by using borehole tiltmeters at geological sequestration sites. We also found differences associated with $CO_2$ phases in velocity and strain changes during injection.

Sleep is associated with definite changes in respiratory function in normal human beings. During sleep, there is loss of voluntary control of breathing and a decrease in the usual ventilatory response to both low oxygen and high carbon dioxide levels. Especially, rapid eye movement (REM) sleep is a distinct neurophysiological state associated with significant changes in breathing pattern and ventilatory control as compared with both wakefulness and non-rapid eye movement (NREM) sleep. REM sleep is characterized by erratic, shallow breathing with irregularities both in amplitude and frequency owing to marked reduction in intercostal and upper airway muscle activity. These blunted ventilatory responses during sleep are clinically important. They permit marked hypoxemia that occurs during REM sleep in patients with lung or chest wall disease. In addition, sleep-disordered breathing (SDB) is more frequent and longer and hypoventilation is more pronounced during REM sleep. Although apneic episodes are most frequent and severe during REM sleep, most adults spend less than 20 to 25% of total sleep time in REM sleep. It is, therefore, possible for patients to have frequent apneas and hypopneas during REM sleep and still have a normal apnea-hypopnea index if the event-rich REM periods are diluted by event-poor periods of NREM sleep. In this review, we address respiratory physiology according to sleep stage, and the clinical implications of SDB and hypoventilation aggravated during REM sleep.

Objectives The purpose of this study is to report the case of fecal impaction in a child without any abdominal symptoms treated by taking herbal medicine. Methods We examined a 7-year-old girl who had normal bowel movement and defecation per day, and had no particular abdominal symptoms. Abdominal radiography was taken, and unexpected severe fecal impaction was observed throughout the abdominal cavity, filled with intestinal gas and feces. According to the subject's parents, she had no generalized symptoms, such as abdominal pain or distension, and had on a regular diet and normal bowel movement daily. She was treated with herbal medicine (Daeseunggi-tang) for 23 days. While she was on the therapy, numbers, doses, bowel movements, and radiography were checked and recorded. Results During the treatment, her stool was softened, and fecal impaction was relieved as showed by abdominal radiography. Conclusions We have identified that there are cases where subjects have no symptoms of abdominal pain, despite presence of severe fecal impaction. In addition, it was found that Daeseunggi-tang is effective in fecal impaction in childhood.

Objective: If non-surgical treatment fails, arthroscopic rotator cuff repair (ARCR) is recommended, and ARCR considers graft augmentation in consideration of size, direction, and re-tear. It is reported to have potential benefits by improving the healing rate as it can fill the gaps that have been left behind. The purpose of this study is to investigate the effect of structural changes observed after ARCR on muscle action through magnetic resonance imaging and to investigate the effect of appropriate physical therapy required for graft augmentation in the general ARCR rehabilitation protocol. Case presentation: A 47-year-old male hospitalized for postoperative rehabilitation following ARCR participated in a 5-week physical therapy intervention. The postoperative day was 6 months, but due to shooting pain and shoulder dysfunction,and the movement of the shoulder was compensatory motion, not normal motion. Physical agents, manual therapy, and supervised exercise for 110 minutes per session were performed 3 times a week, and pain intensity, range of motion, function, and strength were evaluated. Results: As a result of the study, the patient showed positive improvement in pain intensity, range of motion, function, and strength. In addition, normal scapulohumeral rhythm movement was observed. Conclusions: According to the results of this case, appropriate physical therapy according to the compensatory motion shown in the structural changes after ARCR can positively improve the pain intensity, range of motion, function, and strength of ARCR patients.
