The authors assessed the relationship between exposure to ambient particulate matter and suicide in urban settings during a 1-year period.The association was determined using time-stratified case-crossover approach which subjects served as their own controls. All cases (4,341) 2004 that occurred seven cities Republic of Korea were included. Hourly mean concentrations < or =10 microm aerodynamic diameter (at 106 sites cities) =2.5 13 one city) measured. percent increase risk associated with...
Plasmodium vivax malaria reemerged in the Republic of Korea 1993 near Demilitarized Zone (DMZ). We reviewed clinical features 101 symptomatic patients with malaria. Of patients, 77 (76.3%) were veterans who had served DMZ; their median age was 23 years. The duration minimum latent period > 6 months 66.2% (51 77) (median, 278 days). Tertian fever developed 69 (68.3%). Severe thrombocytopenia platelet counts < 60,000/microL common (29.6% patients). parasite densities ranged 32-52,127...
The purpose of this study was to investigate the nationwide prevalence childhood asthma, eczema and other allergic diseases in Korean school-age children (8-11 yr old) assess difference between residential areas.Among 6,279 elementary schools, 427 schools were randomly selected according area (metropolitan, provincial, rural, industrial area) by cluster sampling method.Parents students completed a modified version questionnaire formulated International Study Asthma Allergies Childhood...
The relationship between air pollution and daily mortality for the period 1991-1995 was examined in two Korean cities, Seoul Ulsan. observed concentrations of sulfur dioxide (SO2; mean = 28.7 ppb), ozone (O3; 29.2 total suspended particulates (TSP; 82.3 microg/m3) during study were at levels below Korea's current ambient quality standards. Daily death counts regressed separately using Poisson regression on SO2, O3, and/or TSP controlling variability weather seasons. When considered singly...
Fine or ultrafine particulate matter (PM) is a mixture of solid and liquid particles, including carbon?centered combustion secondary inorganics, crustal?derived particles. Recently, ambient has been regarded as serious health problem in the Republic Korea. This review focuses on importance PM?induced effects, adverse effects from experimental epidemiological studies. There widespread evidence that short?term increases result increased mortality morbidity adults children, even at low levels....
This study assessed the health risks for children exposed to phthalate through several pathways including house dust, surface wipes and hand in child facilities indoor playgrounds.The samples were collected from various children's (40 playrooms, 42 daycare centers, 44 kindergartens, indoor-playgrounds) both summer (Jul-Sep, 2007) winter (Jan-Feb, 2008). Hazard index (HI) was estimated non-carcinogens examined phthalates diethylhexyl (DEHP), diethyl (DEP), dibutyl-n-butyl (DnBP), butylbenzyl...
The goal of this study was to investigate the short-term effect ambient air pollution on emergency department (ED) visits in Seoul for asthma according patients' prior history allergic diseases.Data ED from 2005 2009 were obtained Health Insurance Review and Assessment Service. To evaluate risk related pollutants (carbon monoxide [CO], nitrogen dioxide [NO2], ozone [O3], sulfur [SO2], particulate matter with an aerodynamic diameter <10 μm [PM10]), a generalized additive model Poisson...
Objectives Many epidemiological studies have suggested that a variety of medical illnesses are associated with suicide. Investigating the time-varying pattern care utilization prior to death in suicides motivated by physical would be helpful for developing suicide prevention programs patients illnesses. Methods Suicides were identified investigator's note from National Police Agency, which was linked data Health Insurance Review and Assessment. We investigated patterns during 1 year using...
Purpose:The study aims to classify schools based on traffic pollutants and their complex sources, assess the environment, determine state of allergic diseases among students using International Study Asthma Allergies in children (ISAAC) questionnaire, connection air pollutants.Materials Methods: A total seven were divided into three categories according characteristics surrounding environments: traffic-related zones, two source zones I (urban), II (industrial complex).ISAAC questionnaires...
A group of 82 households in a new-built apartment complex Seoul, Korea participated an investigation to examine the symptoms sick building syndrome (SBS) using houseplants for two observation periods. The present study confirmed decrease formaldehyde content airtight chamber containing pot with fatsia plants. Houseplants affected general air conditions, such as increasing relative humidity and decreasing carbon monoxide dioxide. toxic chemical substances responsible SBS persisted at least...
A case study was conducted to evaluate the quality of indoor air and health-related parameters occupants with consideration indoor-plant placement in office buildings Seoul, Korea from October, 2006 July, 2007. The more than seven floors were categorized into two groups. One group composed six newly-built established 2005 other aged 1990 1992. An room on 3rd floor chosen as place plants 4th without plants. estimated using concentrations air-borne fine particles including formaldehyde...
The atmosphere is the first medium containing hazardous compounds entering living environment. Metropolitan areas contain many industrial complex with high emissions of volatile organic (VOCs), and consequently also large-scale exposure groups. As respiration most important part human pathway, should be treated greater importance than other media. It therefore very to monitor emission air pollutants (HAPs) measure concentration VOCs in such areas. essential establish basic measures order...
