The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the(More)
BACKGROUND Actigraphy has become an important tool in sleep research, however, most actigraphic models have had little evaluation of their sleep scoring software. Some reports have described poor agreement of actigraph and polysomnogram (PSG) results. In this study, we examined the accuracy of the Actiwatch-L instrument with Actiware((R)) software version(More)
PURPOSE Korean adolescents have severe nighttime sleep deprivation and daytime sleepiness because of their competitive educational environment. However, daytime sleep patterns and sleepiness have never been studied using age-specific methods, such as the pediatric daytime sleepiness scale (PDSS). We surveyed the daytime sleepiness of Korean adolescents(More)
We conducted a case-control study to investigate whether vascular endothelial growth factor (VEGF -2578, -1154, -634, and 936) and kinase insert domain containing receptor (KDR -604, 1192, and 1719) polymorphisms are associated with moyamoya disease. Korean patients with moyamoya disease (n = 107, mean age, 20.9±15.9 years; 66.4% female) and 243 healthy(More)

Atomic nuclei have a shell structure in which nuclei with 'magic numbers' of neutrons and protons are analogous to the noble gases in atomic physics. Only ten nuclei with the standard magic numbers of both neutrons and protons have so far been observed. The nuclear shell model is founded on the precept that neutrons and protons can move as independent(More)
We investigated the neuroprotective effects of human placental extracts (HPE) and the effects of HPE on recovery of cognitive and behavioral function on hypoxic-ischemic brain injury in the newborn rat. The right common carotid arteries of 7-day-old rats were coagulated, and rats were then exposed to 8% oxygen. Immediately before and again at three times(More)

Recent calculations suggest that, at late times in the r-process, the rate of neutron capture by 130 Sn has a significant impact on nucleosynthesis. Direct capture into low-lying bound states is likely the dominant reaction in the r-process near the N=82 closed shell, so reaction rates are strongly impacted by the properties of neutron single particle(More)

The rate of the 17 F(p,γ) 18 Ne reaction is of significant importance in astrophysical events like novae and x-ray bursts. The decay of 17 F is thought to help drive the expansion of the nova envelope, and the 17 F(p,γ) 18 Ne reaction affects the production of 18 F, a target of gamma-ray astronomy, as well as being an important link in the (α,p) reaction(More)

The magnitude of the 15 N(n, γ) 16 N reaction rate in asymptotic giant branch stars depends directly on the neutron spectroscopic factors of low-lying 16 N levels. A new study of the 15 N(d, p) 16 N reaction is reported populating the ground and first three excited states in 16 N. The preliminary spectroscopic factors are near unity as expected from shell(More)

The neutron-deficient nucleus 107 Sn has been studied by using the one-neutron knockout reaction. By measuring the decay γ rays and momentum distributions of reaction residues, the spins of the ground, 5/2 + , and first-excited, 7/2 + , states of 107 Sn have been assigned by comparisons to eikonal-model reaction calculations. Limits on the inclusive and(More)
