In order to investigate experimentally the clinical effects of Chungsimjeongchun-Tang that have been widely used for cardiac asthma, dyspnea and coughs secondary to the appoplexy and cardiac diseases, the water extract of Chungsimjeongchun-Tang was conducted to the effects on the anti-histamine action and respiratory system in mice, guinea-pigs, rabbits and cats. The following results of Chungsimieongchun-Tang were obtained. Spontaneous motility of the isolated ileum of mice and rabbits was strongly suppressed and contractions of the isolated ileum of mice and guinea-pigs induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Anti-histamine action was noted. Antitussive action on the mechanically irritative cough in cats was recognized. Expectorant action on the leakage of dye in the respiratory tract of rabbits was also shown.

In this paper, the effect of $O_2$ concentration on NO removal and $NO_2$ generation by corona discharge from simulated flue gas was measured and estimated for the wire-plate reactor. $NO_2$ removal rate was 0$\sim$30[%] under about 3.4[%] of oxygen concentration, however, it was difficult to remove NOx over 3.4[%] of oxygen concentration. It may be due to generate $NO_2$ from $N_2$ and $O_2$ molecules and converse NO to $NO_2$ by 0 and $O_3$. Magnetic field applied to electric field in plasma was very effective for NOx removal under 2[%] of $O_2$ concentration.

본 논문에서는 물 속에 있는 대장균의 양을 측정하는 새로운 방법을 제안하였다. 이는 대장균의 배양시 생성되는 $CO_{2}$ 가스 생성에 의한 압력의 증가율을 측정함으로써 이루어진다. 압력 및 온도 센서를 이용하여 제작된 계측기에 의하여 측정한 결과 $4{\sim}6$시간만에 대장균의 양을 측정할 수 있어 기존의 방법에서 소요되는 $24{\sim}72$시간보다 신속한 측정 이 가능함을 확인하였다.

Objectives This study is aimed to identify and evaluate the already developed clinical practice guidelines (CPGs) of temporomandibular disorders (TMD) and contribute to making decisions in developing Korean medicine CPG of TMD. Methods We searched electronic database and selected CPGs of TMD according to the inclusion and exclusion criteria. Then, we made appraisal of selected CPGs by using AGREE II (Appraisal of Guidelines for Research & Evaluation II). Results Four CPGs are included and appraised with AGREE II. Among 6 domains of AGREE II, all CPGs failed to score over 60% in four domains. Only one CPG mentioned acupuncture as an adjunctive treatment for myofascial TMD. Conclusions It is difficult to indicate that included CPGs are with sufficient quality to recommend and it appears not to be appropriate to apply these already developed CPGs in Korean medicine clinical fields. Therefore, developing a new Korean medicine clinical practice guideline of TMD is required.

Gate and data drivers are essential for driving active matrix display. In this study, we integrate drivers with a-Si:H to develop a compact, better reliability and cost effective display. We design and fabricate drivers with conventional a-Si:H thin film transistors (TFTs). The output voltages are investigated according to the input voltage, temperature and operation time. Based on these studies, we propose here a new driver to prevent gate line from the floated state. For the external coupled voltage fluctuation, the proposed driver shows better stability.

An RC oscillator using amorphous silicon thin film transistors was developed. The oscillation frequency and its dependence on resistance and bias voltage were studied. The frequency was controlled by adjusting the feedback resistance of the oscillator. The highest measured frequency of the oscillator was around 140 kHz, which is acceptable for low-end radio frequency identification (RFID). Since a low-end RFID circuit needs low cost and a simple process, an amorphous silicon oscillator is suitable.

Breast cancer detection using electrical impedance techniques is based on numerous experimental findings that cancerous tissues have higher electrical conductivity values than normal tissues. Lately, by taking advantage of the structure of current flows underneath a planar probe of array electrodes, a mathematical formula to find lesions from a measured trans­admittance map has been derived. In order to experimentally validate its mathematical analysis and the suggested lesion estimation algorithm, we developed a 256-channel trans-admittance scanner (TAS) for probing anomalies underneath a planar array of electrodes. In this paper, we describe the design and implementation of the TAS. Its performance together with the lesion estimation algorithm was evaluated using saline phantoms. Further studies are proposed to validate the system on human subjects.

$SnO_2$ thin films were deposited on fused silica substrate by pulsed laser deposition under transverse magnetic field. We have explored the effects of magnetic field and ablation laser wavelength on the optical properties of laser-induced plasma plume and structural characteristics of the deposited $SnO_2$ films. Optical emission from the plume was monitored using an optical fiber to examine the influence of magnetic field on the population of the excited neutral and ionic species and their decay with times after laser ablation. Also, we employed photoluminescence, x-ray diffraction, and UV-Vis absorption to characterize $SnO_2$ films.
