Abstract This study investigates the spatial characteristics of nonzero rain rates to develop a probability density function (PDF) model precipitation using rainfall data from Tropical Rainfall Measuring Mission (TRMM) satellite. The minimum χ2 method is used find good estimator for rain-rate distribution between gamma and lognormal distributions, which are popularly in simulation PDF. Results sensitive choice dynamic range, but both distributions match well with PDF data. Comparison sample...
Bacterial meningitis remains a serious cause of morbidity and mortality in childhood, despite the availability effective vaccines against Haemophilus influenzae type b (Hib) or Streptococcus pneumoniae. The purpose this study was to analyze data on bacterial cases Korea from 1996 through 2005. information all hospitalized bacteria-proven obtained 17 university hospitals nationwide. A total 402 were identified. Of these, 125 (29.9%) neonates. agalactiae most common bacteria responsible for 99...
Coronavirus disease 2019 (COVID-19) vaccines are currently authorized for emergency use in adolescents aged 12-17 years; however, there is concern and uncertainty regarding the safety necessity of COVID-19 vaccination. A survey was carried out to assess attitudes acceptance towards vaccination adolescents.A nationwide web-based conducted among years their parents between June 29 July 8, 2021 on a platform provided by Ministry Education.A total 341,326 272,914 participated this study....
Background: The COVID-19 pandemic’s transition to an endemic phase emphasizes the importance of vaccination. Despite initial strong immunogenicity, waning vaccine-induced immunity requires further investigation. Therefore, this study evaluated immunogenicity BNT162b2 vaccine in adolescents, focusing on spike-specific and neutralizing antibody kinetics following primary booster vaccinations as well impact breakthrough infections. Methods: This observational included 157 adolescents 12–17...
The purpose of this study was to identify the major etiological agents responsible for invasive bacterial infections in immunocompetent Korean children.We retrospectively surveyed children caused by eight pediatric bacteria, namely Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, agalactiae, pyogenes, Listeria monocytogenes, and Salmonella species that were diagnosed at 18 university hospitals from 1996 2005.A total 768 cases identified.S....
YearsThis study aimed to assess the immune status of Korean population against hepatitis A virus (HAV).Residual serum samples from 2008 2010 were collected diagnostic laboratories and a total 1,872 analyzed.Anti-HAV seroprevalence was 57.3% in subjects aged 1-4 yr, 69.8% at 5-9 yr decreased 38.8% 10-14 13.0% 15-19 11.7% 20-29 yr.Seroprevalence increased with increasing age: 52.2% 30-39 83.2% 40-49 81.4% 50-59 93.2% 60-69 95.1% 70-79 yr.The most susceptible age group consisted 10-29...
In Kawasaki disease (KD), high dose intravenous immunoglobulin (IVIG) significantly lowers the coronary complications. However, some patients either do not respond to initial therapy or develop We aimed identify predictive factors for unresponsiveness IVIG and artery dilatation (CAD; defined by Z-score≥2.5) in acute phase convalescent phase.A retrospective review was conducted of 703 with KD, admitted Gachon University Gil Medical Center between January 2005 June 2013. The were divided into...
Abstract Gaseous and particulate 21 PAHs were monitored at a residential site in Ulsan, South Korea, over three seasons (December 2013–August 2014). The mean concentrations of Σ highest winter (16.2 ± 8.2 ng/m 3 ), followed by spring (8.37 4.53 ) summer (6.23 2.53 ). gaseous concentration (7.39 4.39 was 2.7 times higher than that (2.70 3.38 To identify the sources (both types their areas), diagnostic ratios, principal component analysis, concentration-weighted trajectory (CWT) used. results...
Clinical characteristics and risk factors of hand-foot syndrome were investigated in patients who received capecitabine-containing chemotherapy. Toxicity data analyzed from 179 4 prospective clinical trials testing docetaxel/capecitabine/cisplatin stomach cancer, capecitabine/cisplatin biliary or vinorelbine/capecitabine breast cancer. Hand-foot was reported 116/179 (64.8%) patients, with grade 3 8/179 (4.5%). first developed within the chemotherapy cycles 100/116 (86.2%) median onset for...
Abstract Four years of outgoing longwave radiation (OLR) and rainfall data from the Tropical Rainfall Measuring Mission (TRMM) are investigated to find dominant large-scale wave modes in Tropics. By using space– time cross-section analysis spectral analysis, longitudinal latitudinal behaviors overall waves observed. Despite noisy nature precipitation limited sampling by TRMM satellite, pronounced peaks found for Kelvin waves, n = 1 equatorial Rossby (ER), mixed Rossby–gravity (MRG)....
Seroepidemiology of Varicella-Zoster Virus in KoreaThis study was designed to assess the immune status Korean population against varicella-zoster virus (VZV) through a seroepidemiologic study.Residual blood samples were collected from diagnostic laboratories throughout Korea.Samples October 2009 March 2010 persons 0-79 yr age and tested by ELISA (Enzygnost®; Dade Behring, Schwalbach, Germany).Total seroprevalence subjects 1-79 89.6%.Seroprevalence increased as 67.3% 1-4 94.2% 10-14 over 20...
Background and objectives Multipotent mesenchymal stromal cells (MSCs) represent a promising cell-based therapy for number of inflammatory or autoimmune diseases. Herein, Toll like receptor (TLR) expression by MSCs their immune regulatory roles are investigated. In this study, we investigated the influence TLR on response, proliferation, differentiation potential human turbinated MSC (hTMSC) cultures in vitro. Subjects Methods After isolating hTMSCs from discarded inferior turbinate tissue,...
Newborn infants, including premature are high-risk patients susceptible to various microorganisms. Catheter-related bloodstream infections the most common type of nosocomial in this population. Regular education and training medical staffs important as a preventive strategy for central line-associated (CLABSIs). Bundle approaches use checklists during insertion maintenance catheters effective measures reduce incidence CLABSIs. Chlorhexidine, commonly used skin disinfectant before catheter...
Background:The coronavirus disease-2019 (COVID-19) pandemic has contributed to the change in epidemiology of many infectious diseases.This study aimed establish pre-pandemic pediatric invasive bacterial infection (IBI).Methods: A retrospective multicenter-based surveillance for IBIs been maintained from 1996 2020 Korea.IBIs caused by eight bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Streptococcus agalactiae, pyogenes, Listeria...
Purpose Hand-foot-mouth disease (HFMD) is a common viral illness in children, which usually mild and self-limiting. However, recent epidemics of HFMD Asia, enterovirus 71 (EV71) has been recognized as causative agent with severe neurological symptoms or without cardiopulmonary involvement. was epidemic Korea the spring 2009. Severe cases complications including death have reported. The clinical characteristics children neurologic manifestations EV71 were studied Ewha Womans University...
Background: Invasive bacterial infection (IBI) remains a major burden of mortality and morbidity in children. As coronavirus disease 2019 (COVID-19) emerged, stringent nonpharmaceutical interventions (NPIs) were applied worldwide. This study aimed to evaluate the impact NPIs on pediatric IBI Korea. Methods: From January 2018 December 2020, surveillance for IBIs caused by 9 pathogens ( S. pneumoniae , H. influenzae N. meningitidis agalactiae pyogenes aureus Salmonella species, L....
