Objectives : The aim of this study is to report the effect of herbal medicine and acupuncture on a breastfeeding woman's postpartum urticaria which was unresponsive to a 1st generation antihistamine and a topical steroid. Methods : Wheals and pruritus occurred to a 36-year-old breastfeeding woman 2 days after the parturition. Symptoms were unresponsive to about a week of systemic antihistamine and topical steroid treatments. GamiSamul-tang herbal decoction was administered three times a day for the first 21 days and twice a day for the next 10 days of the treatment. Acupuncture treatment was applied to 12 acupoints (both sides of LI04, LR03, ST36, LI11, SP10, SP6) for 15 minutes once a week, 5 times in total. The patient's symptom was evaluated with Weekly Urticaria Activity Scale (UAS7) and Visual Analogue Scale for Worst Pruritus within 24 hours ($VAS_{Pruritus}$) each time the patient visited out-patient department. Results : The scores of UAS7 and $VAS_{Pruritus}$ at the baseline were 38 and 8.2 respectively. 10 days after the herbal medicine and acupuncture treatment began, both decreased to 0 and wheal, pruritus, erythema didn't appeared again for the rest of the follow up periods. Conclusions : This study shows the possibility of using GamiSamul-tang and acupuncture to treat postpartum urticaria.

Highly photosensitive and wide bandgap amorphous silicon oxide (a-$SiO_x$:H) films were developed at low temperature ranges ($100{\sim}150^{\circ}C$) with employing plasma-enhanced chemical vapor deposition by optimizing $H_2/SiH_4$ gas ratio and $CO_2$ flow. Photosensitivity more than $10^5$ and wide bandgap (1.81~1.85 eV) properties were used for making the a-$SiO_x$:H thin film solar cells, which exhibited a high open circuit voltage of 0.987 V at the substrate temperature of $100^{\circ}C$. In addition, a power conversion efficiency of 6.87% for the cell could be improved up to 7.77% by employing a new n-type nc-$SiO_x$:H/ZnO:Al/Ag triple back-reflector that offers better short circuit currents in the thin film photovoltaic devices.

통신 시장의 경쟁 심화, 급속한 기술 발전은 All-IP 기반의 공통 인프라와 다양한 고품질 융합 서비스의 환경으로 패러다임을 변화시키고 있으며, 이러한 변화에 따라 IP 서비스에 대한 과금 체계 또한 진화하고 있다. 본 고에서는 그 중요성이 증대하고 있는IP 서비스의 과금 시스템에 대하여 개념과 기술 동향, 관련 표준화 활동을 살펴보고, 차세대 네트워크(BcN)를 대비한 과금 정책에 대하여 기술한다. 그리고 이와 같은 기술동향 및 과금 정책을 효과적으로 구현하기 위해 ETRI에서 개발중인 고속회선용 정밀과금 시스템을 소개한다.

Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in the neonatal population. The aim of this study is to evaluate surgical indication and prognostic factors of NEC. Clinical data of seventy patients, diagnosed as NEC between January 2000 & January 2007, were reviewed retrospectively. Fifty-seven patients had medical treatment and 7 of them died. Thirteen patients who presented with pneumoperitoneum on plain abdominal film or were refractory to medical treatment received surgical treatment, and 5 of them died. All the expired 12 patients weighed less than 2500 g. Twenty out of seventy patients showed thrombocytopenia, and 11 patients of them died. The finding of pneumoperitoneum and thrombocytopenia could be the most important surgical indication. Prematurity, low birth weight and thrombocytopenia were related to a bad prognosis. NEC patients who presents with these findings must be considered for close observation and intensive care.

Many control techniques have been proposed in order to improve the control performance of discrete-time domain control system. In the position control system using a DC servo motor as control system, the response-characteristic of system is controlled by the I-PD controller. In the I-PD longer if gains of I-PD controller are unsuitable. In this paper, therefore, a expanded I-PD control system is constructed by inserting a pre-compensator at out terminal of I-PD controller. It is implemented by neural network with two hidden layers. From the result of computer simulation in the proposed control algorithm, its usefulness is verified.
