Artificial intelligence, which has been applied as an innovative technology in multiple fields of healthcare, analyzes large amounts of data to assist in disease prediction, prevention, and diagnosis, as well as in patient monitoring. In obstetrics, artificial intelligence has been actively applied and integrated into our daily medical practice. This review provides an overview of artificial intelligence systems currently used for obstetric diagnostic purposes, such as fetal cardiotocography, ul

This study aimed to examine the impact of term LBW on short-term neonatal and long-term neurodevelopmental outcomes in children 5-7 years of age. This is a population-based cohort study that merged national data from the Korea National Health Insurance claims and National Health Screening Program for Infants and Children. The participants were women who gave birth at a gestational age of ≥ 37 weeks between 2013 and 2015 in the Republic of Korea, and were tracked during 2020 for the neurodevelopm

Hyperemesis gravidarum is known to be associated with poor perinatal outcomes. This study aimed to identify pre-pregnancy risk factors for hospital admission in women with hyperemesis gravidarum. We enrolled women who had delivered between 1 January 2013 and 31 December 2015, and had undergone a national health screening examination through the National Health Insurance Corporation 1-2 years before their first delivery. Multiple logistic regression analysis was performed to estimate the risk fac

This paper helps to set the scene for this special issue on automotive restructuring and policy responses. It starts by providing a brief introduction to the different inventory and supply-chain management approaches dominant within the industry at different stages of its evolution, before moving on to outline the spatial implications of these different approaches. The paper then presents a transactions–costs conceptual framework for analysing key features of the auto manufacturing and supply-ch

This study aims to evaluate the perinatal outcomes of preterm premature rupture of membrane (PPROM) with latency periods at 33 + 0–36 + 6 weeks of gestation. This retrospective case-control study included women with singleton pregnancies who delivered at 33 + 0–36 + 6 weeks at Korea University Ansan Hospital in South Korea between 2006–2019. The maternal and neonatal characteristics were compared between different latency periods (expectant delivery ≥72 h vs. immediate delivery <72 h). Data w

We investigated changes in gene expression of cervical collagens, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinases (TIMPs) during pre-gestational uterine cervical excision and/or inflammation-induced preterm labor in mice. Forty sexually mature female mice were uniformly divided into four groups: sham, cervical excision, lipopolysaccharide (LPS) injection, and cervical excision plus LPS injection. Partial cervical tissue excision was performed at five weeks of age be

The purpose of this prospective study was to investigate the changes in the circulating levels of cathepsin B and D in pregnancy. We obtained longitudinal cathepsin B and D levels in 76 healthy pregnant women in the first and third trimesters and compared these levels with 20 non-pregnant controls. The plasma levels of soluble cathepsin B and D were measured using an enzyme-linked immunosorbent assay kit. The cathepsin D concentrations in the third trimester were significantly higher than that i

To study physiological roles of plant small GTP binding proteins, we isolated a cDNA clone (ORrab2) encoding the rab-related small GTP binding protein from rice (Oryza sativa L. IR-36) by using human cDNA rab2 as a probe. The deduced amino acid sequence of the ORrab2 gene shared all the conserved regions, important for GTPase/GTP binding activities, with those of other small GTP binding proteins. ORrab2 is a 1028 bp long cDNA, encodes a 23.2 kDa protein which shows 85.2% similarity on the amino

Increasing numbers of free trade and economic partnership agreements have been concluded among many countries in East Asia, and economic integration has progressed rapidly on both a de facto and de jure basis. However, as the authors of this book argue, integration may intensify regional inequalities in East Asia and so this process has attracted much attention of late. Will it actually succeed in achieving greater economic growth or will it in fact cause growing regional disparity?

Fetal growth restriction (FGR) is one of the leading causes of perinatal morbidity and mortality. Many studies have reported an association between FGR and fetal Doppler indices focusing on umbilical artery (UA), middle cerebral artery (MCA), and ductus venosus (DV). The uteroplacental-fetal circulation which affects the fetal growth consists of not only UA, MCA, and DV, but also umbilical vein (UV), placenta and uterus itself. Nevertheless, there is a paucity of large-scale cohort studies that
