The average annual rate of incidence, 105.0/100,000 in children <5-year-old is the second highest reported rate in the world.

AIM: To evaluate the relationship between abnormal Doppler velocimetry and adverse perinatal outcomes in pregnancies with borderline amniotic fluid index (AFI). METHODS: Medical records of 3740 pregnancies with known AFI and Doppler velocimetry measurements within 2 weeks of delivery, and delivered between January 1996 and December 2003, were retrospectively analyzed. Borderline AFI was defined as 5 cm < AFI < or = 8 cm. For the umbilical artery, Doppler velocimetry was considered abnormal when

BACKGROUND: To determine whether the measurement of beta-human chorionic gonadotropin (beta-HCG) level in the vaginal washing fluid could be useful for the diagnosis of premature rupture of membranes. METHODS: Totally, 120 pregnant women were enrolled in this study. Subjects were divided into four groups [group I, no preterm labor and term delivery (n = 38); group II, preterm labor and term delivery (n = 12); group III, preterm labor and consequent premature delivery (n = 24); group IV, preterm

OBJECTIVES: To evaluate the effect of nicotine on the production of soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) in human umbilical vein endothelial cells (HUVECs) and trophoblast cells, and to assess the involvement of alpha 7 nicotinic acetylcholine receptor (alpha7 nAChR) in this process. METHODS: Commercially available full-term placental trophoblasts and HUVECs derived from the umbilical cord of a normal pregnancy were used. The expression of alpha7 nAChR was asse

Recently, in many shopping streets, vacant shops have been increasing due to changes in consumer behavior, aging of merchants. Also, because of the evolution of the internet and transportation, consumers can purchase products quickly and easily through the internet and supermarkets. As a result, consumers no longer need to go shopping directly, so it is expected that in the future, consumers will no longer go to shopping streets to purchase products. Accordingly, the survival of shopping streets

本研究では、江川省春川市の周辺地域の地価に対する無電柱化の影響を分析した。 この研究の結果は以下の通りである。 1）無電柱化は経済的に算定しにくい公共便益増進に寄与する。このような公共便益の増進が地価に反映された。 2）時間の経過により無電柱化の意味と効果は減少したが、公共便益増進の効果は徐々に他の変数によって吸収されているように見える。 3）地価への影響は、住居用として利用される土地より商業用として利用される土地が大幅に変化した。

Since the advent of the modern von Neumann computer in the 1940s, startling advances have been made in computing technology with the creation of innovative, reliable, and faster electronic components, from vacuum tubes to transistors. Computing power has risen exponentially over relatively brief periods of time as Moore’s law projected a salient trend for the growth in memory-chip performance, estimating the capacity of the integrated circuit to double every 18 months. Although these development

In this study, unconfined compression test and triaxial test were performed to evalute a representative rigidity index () of Korean soft deposit, which should be required to estimate a coefficient of consolidation from the piezocone dissipation test. From these test results, representative rigidity indices were proposed as 27 for the western coast soft deposit, 29 for the sourthern coast soft deposit, and 22 for the eastern coast soft deposit. Those proposed rigidify indices were applied to anal
