RISK FACTORS AND INCIDENCE OF FALLS AMONG FIFTH- AND SIXTH-GRADE CHILDREN IN SEOUL, SOUTH KOREA.

This study aimed to determine the incidence of falls among children in South Korea, and the risk factors associated with these falls in order to develop preventive strategies. We studied 1,044 elementary school students in the fifth and sixth grades from Seoul, South Korea and evaluated the incidence of falls based on four surveys conducted in June, September, and December 2010 and February 2011. The surveys included the number of falls, the types of medical care received, and the potential factors associated with those falls.

Estimates of induced abortion in South Korea: health facilities survey.

Aim: The aim of this study was to estimate the national rates of induced abortion in South Korea, where no quantitative national studies of abortion exist because the procedure is illegal.

Materials And Methods: A survey of 25 hospitals and 176 private clinics that provide induced abortions was conducted in 2005. The data were analyzed to estimate the nationwide rate of induced abortion.

Epidemiology of hemorrhagic fever with renal syndrome in endemic area of the Republic of Korea, 1995-1998.

We conducted an epidemiologic study to understand temporal and spatial patterns of hemorrhagic fever with renal syndrome (HFRS) in the Republic of Korea (ROK). We estimated the incidence among civilians in endemic areas through the active surveillance system during the major epidemic periods, from September to December, between 1996 and 1998. We also estimated the prevalence among Korean military personnel from 1995 to 1998.

[A study of immune response to hepatitis B vaccine & HBV DNA in isolated anti-HBc positive subjects].

Objectives: The aim of this study was to evaluate the response to a hepatitis B vaccination, and investigate the HBV DNA in subjects with isolated anti-HBc.

Methods: 34 subjects with persistent isolated anti-HBc were included in the study. 32 subjects negative for HBsAg, anti-HBs and anti-HBc were included as a control group.

Influence of the serotonin transporter promoter gene polymorphism on susceptibility to posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) is a prevalent anxiety disorder marked by behavioral, physiologic, and hormonal alterations. The etiology of PTSD is unknown, although exposure to a traumatic event constitutes a necessary, but not sufficient, factor. Serotonergic dysfunction has been implicated in PTSD.

Prevalence of antibodies to the circumsporozite protein of Plasmodium vivax in five different regions of Korea.

Malaria has recently re-emerged in the Republic of Korea (ROK), but only few malaria seroprevalences were reported. We obtained 1014 serum samples from inhabitants of five regions of ROK during the high transmission season between June and August in 2001. The levels of anti-circumsporozoite protein (CSP) antibody were assessed in samples using an indirect enzyme-linked immunosorbent assay (ELISA).
