Social Proximity Applications (SPAs) has been an emerging hot topic in recent mobile research communities. However, the traditional SPA interfaces rely on heavy interaction load in visual attention. This is always problematic when people are on the move. This paper describes our research-in-progress in designing and developing a suitable SPA interface for(More)
Non-invasive prenatal testing of trisomy 21 (T21) is being actively investigated using fetal-specific epigenetic markers (EPs) that are present in maternal plasma. Recently, 12 EPs on chromosome 21 were identified based on tissue-specific epigenetic characteristics between placenta and blood, and demonstrated excellent clinical performance in the(More)
OBJECTIVES The aim of this study was to investigate the clinical and biochemical profiles according to homeostasis model assessment of insulin resistance (HOMA-IR) in Korean polycystic ovary syndrome (PCOS) patients. METHODS In 458 PCOS patients diagnosed by the Rotterdam European Society for Human Reproduction and Embryology (ESHRE) criteria,(More)
BACKGROUND Cell-free fetal DNA and cell-free total DNA in maternal circulation have been proposed as potential markers for noninvasive monitoring of the placental condition during the pregnancy. However, the correlation of and change in cell-free fetal DNA and cell-free total DNA in spontaneous abortion (SA) with fetal chromosomal aneuploidy have not yet(More)
Choriocarcinoma is a highly invasive and metastatic neoplasm which arises in women of reproductive age. It can be either gestational or nongestational in origin, but the latter form is very rare. Choriocarcinoma is characterized by the production of human chorionic gonadotropin. It can metastasize to distant organs such as lung, brain, liver, kidney, and(More)
Rice koji, used early in the manufacturing process for many fermented foods, produces diverse metabolites and enzymes during fermentation. Using gas chromatography time-of-flight mass spectrometry (GC-TOF-MS), ultrahigh-performance liquid chromatography linear trap quadrupole ion trap tandem mass spectrometry (UHPLC-LTQ-IT-MS/MS), and multivariate analysis(More)
Inadequate dietary intake and prolonged undernourishment can lead to short term and long term consequences, which can deplete financial, physical, and social capital, further exacerbating the cycle of undernutrition, poverty, and unhealthy household environment that most food-insecure families already have. Children are a particular focus of interest(More)
OBJECTIVES To determine the diagnostic performance of transrectal ultrasound in virgin patients with polycystic ovary syndrome (PCOS) by receiver operating characteristic (ROC) curve analysis, compared with conventional transvaginal ultrasound assessment. METHODS Ultrasound examinations were performed in 963 Korean women, with transvaginal transducers in(More)
BACKGROUND Quantification of cell-free fetal DNA by methylation-based DNA discrimination has been used in non-invasive prenatal testing of fetal chromosomal aneuploidy. The maspin (Serpin peptidase inhibitor, clade B (ovalbumin), member 5; SERPINB5) gene, located on chromosome 18q21.33, is hypomethylated in the placenta and completely methylated in maternal(More)
Bicycling has become a mainstream activity among the environmental aware generation. Bicycling communities have gradually shown interests in quantitative data of the bicycling experiences such as road roughness, inclination, pollution, etc. Bikers utilize these data to infer the possible stamina cost and quality of surroundings. This supports them to make a(More)
