Restless legs syndrome(RLS) is a common but frequently undiagnosed sensorimotor disorder. It has distinct clinical manifestations and also it is fairly common in late adulthood. However, it is rarely recognized in children because of the difficulties in expressing the signs and symptoms and the lacks of experience of pediatricians about the disease. Although its underlying pathophysiology is not fully understood, the diagnostic criteria of RLS in children were established in the year of 2003. We experienced a case of idiopathic restless legs syndrome in a 10-year-old boy and we present the case with a brief review of related literature. 저자들은 10세 남아에서 수면시와 휴식시에 양측하지에 통증이 악화되고 활동시에 통증이 완화되는 하지불안증후군 1례를 경험하였기에 보고하는 바이다

We investigated the amount of the toxic gases emitted from the Electrostatic Precipitators(ESPs), which are currently used as the indoor air cleaners. The existing wire-to-plate(WTP) and neddle-to-plate(NTP) types of ESP designs are considered as the experimental corona dischargers. Using the voltage, the polarity of wire, the number of needles of NTP as the input variables, we studied the generation characteristics of ozone and $NO_{x}$ and the particle removal efficiency in the ESPs. As the results, we found out that the concentration of ozone, $NO_{2}$ and $NO_{x}$ is increased with increasing the voltage and the number of needles, but the amount of NO is decreased. And we observed that the generation rates of ozone and $NO_{x}$ are mainly related with the corona region through the photographs. Finally the experimental results showed that the particle removal efficiency of ESP with WTP type charger is more superior to that with NTP type chargers at the same voltage.
