Atmospheric pressure plasma is used in the biological and medical fields. Miniaturization and safety are important in the application of apply atmospheric plasma to bio devices. In this study, we made a small, pocket-sized inverter for the discharge of atmospheric plasma. We used pulse power to control the neutral gas temperature at which the, when plasma was discharged. We used direct current of 5 V of bias(voltage). The output voltage is about 1 to 2 kilo volts the frequency is about 80 kilo hertz. We analyzsed the characteristics of the atmospheric plasma using OES(Optical emission spectroscopy) and the Current-Voltage characteristic of pulse power. By calculating of the current voltage characteristics, we were able to determine that, when the duty ratio increased, the power that actually effects the plasma discharge also increased. To apply atmospheric plasma to human organisms, the temperature is the most important factor, we were able to control the temperature by modulating the pulse power duty ratio. This means we can use atmospheric plasma on the human body or in other areas of the medical field.

환경에 방출되어 있는 많은 내분비교란물질들은 사람과 동물의 내분비계에 교란을 일으킬 수 있는 잠재력을 가진다. 뇌의 성분화는 생식소 호르몬 영향하에 비가역적으로 진행되며 흰쥐의 경우 이 시기는 임신말기에서 생후 7∼10일 가량이다. 최근에 본 연구진은 횐쥐의 뇌 성 분화의 결정적인 시기에 발현되는 KAP3유전자를 클로닝하였다 (Choi ＆ Lee, 1999). KAP3의 기능은 신경세포를 포함한 세포에서 aronal tansport를 조절하는 것으로 알
