The results of the study about comparison of Eastern-Western medicine on the Atopic dermatitis were as follows. 1. Atopic dermatitis is chronic eczematous dermatosis which have severe itching, characteristic eruption, easily occur region and pass on chronic relapsing progress and have family history of Atopic disease and hereditary disposition. 2. Atopic dermatitis assume an remarkable clinical aspect and it's diagnosis depends on family history and clinical symptom. 3. In all cases of Western medical treatment is nothing but a symptomatic treatment because can not find out certainly the cause of Atopic dermatitis. 4. Atopic dermatitis is belong to the category of the 'Naesun(내癬)', 'Taeryumchang(胎斂瘡)', 'Samanpoong(四灣風)' etc. in Oriental medicine. 5. The etiology and pathogenesis of Atopic dermatitis in oriental medicine are congenital defect(稟賦不足), internal accumulation of damp and heat(濕熱內鬱), improper diet(飮食不節), exogenous pathogenic factors(外邪侵襲), etc.. 6. The treatments of Atopic dermatitis in oriental medicine are thought effective clear up heat and remove dampness with febrifugal arld diuretic drug(淸熱利濕), invigorate the spleen to resolve dampness(健脾燥濕), nourish Um and blood to relave dryness(滋陰養血潤燥), etc..

The conditions for the protoplast fusion of auxotrophic mutants of Trichoderma koningii were determined. A preparation of commercial enzyme Driselase was used successfully to isolate protoplasts from the 18 hr old mycelium of T. koningii. The yields of protoplasts production were ranged from $0.3{\times}10^8$ to $2.5{\times}10^8$ protoplasts per mg of damp mycelium of various auxotrophic mutant strains. The regeneration frequencies from $9.3{\times}10^{-3}\;to\;2.0{\times}10^{-1}$ were obtained when the protoplasts from auxotrophic mutants were plated on the malt extract medium containing 0.6M $MgSO_4$, and 2% agar, and the optimal concentration of PEG for protoplst fusion was 30%. Exposure of protoplasts to PEG for 10 min was found to be sufficient to induce high frequency heterokaryon formation. Optimal pH of fusion mixture was determined as 5.5, and 1 mM of calcium chloride in fusion mixture was found to be sufficient to enhance protoplast fusion frequency. Under optimal condition, the fusion frequency of the cross between protoplasts from various auxotrophic mutants were $1.6{\times}10^{-2}\;and\;4.1{\times}10^{-2}$.

This paper proposes a novel active damping scheme to suppress LCL-filter resonance with only grid-current feedback control in grid-connected voltage-source converters. The idea comes from the concept of the model reference adaptive control (MRAC). A detailed theoretical derivation is given, and the effectiveness of this method is explained based on its physical nature. According to the control structure of this method, the active damping compensator, which is essentially a second order resonant integrator (SORI) filter, provides an effective solution to damp LCL resonance and to eliminate the need for additional sensors. Compared with extra feedback methods, the cost and complexity are reduced. A straightforward tuning procedure for the active damping method has been presented. A stability analysis is illustrated in the discrete domain while considering a one-step delay. Finally, experimental results are presented to validate the analysis and to demonstrate the good performance of the proposed method.

Objectives : The purpose of this paper is to study how medical experts understood 'Specially Selecting Yangming' for clinical application. Methods : After collecting medical texts related to 'Specially Selecting Yangming', its meaning and clinical application were examined thoroughly. Results : 1. The meaning of 'Specially Selecting Yangming' was identified in different ways according to the meaning of 'Yangming.' It was perceived as Stomach, Yangming meridian, Stomach meridian of Foot Yangming, Spleen and Stomach, Intestine and Stomach by medical experts. 2. Chen Wu-ze and Liu Wan-su understood Wei disease as a form of consumption, and regarded 'Specially Selecting Yangming' as tonifying Yangming while Zhang Zi-he put emphasis on Communicating Stomach Qi(胃氣) through vomiting or purgation. Sun Yi-kui insisted on applying it as a precaution. 3. Li Dong-yuan emphasized the cause of Wei disease to be Damp-Heat in the Summer and suggested Qingshuyiqitang and Qingzaotang as remedy. 4. Zhu Zhen-heng's Purging the South and Reinforcing the North is a more fundamental way of treating Wei disease by stimulating the Water-Fire Axis. Conclusions : Through a diachronic study of 'Specially Selecting Yangming' and its remedy, most medical experts regarded 'Specially Selecting Yangming' as tonifying Yangming, but tonifying Liver and Kidney was thought to be a more fundamental treatment.

Xerostomia due to the subjective dry mouth feeling that may occur even when the salivary gland function reduction is not objectively confirmed. The purpose of this study was to investigate whether or not dry mouth is more sensitive to pain in the oral facial area, which is the main cause of dental problems. The natural products used in this study are Boswellia serrata and seabuckthorn, Both natural substances are known as a representative antioxidant substance rich in vitamins. 4-DAMP was injected into the peritoneal cavity of the experimental animals, and 5% formalin was injected into the face to observe the change of inflammatory pain. Boswellia (15, 30 mg/kg) or seabuckthorn (150, 30 mg/kg, 5 mg/kg) after formalin infusion, As a result, pain response was significantly reduced in the drug-infused group compared to the formalin-infused group (*P<0.05). It was also found that the two drugs were more effective when administered together. Based on these results, we confirm that natural extract can be an alternative treatment modality for the control of oral facial inflammatory pain.

Under foundation shock mats have been used in the current practice in order to reduce/damp vibrations received by buildings through the surrounding environment. Although some investigations have been made on under foundation shock mats performance, their effectiveness in the reduction of railway induced-vibrations has not been fully studied, particularly with the consideration of underneath soil media. In this regard, this research is aimed at investigating performance of shock mat used beneath building foundation for reduction of railway induced-vibrations, taking into account soil-structure interaction. For this purpose, a 2D finite/infinite element model of a building and its surrounding soil media was developed. It includes an elastic soil media, a railway embankment, a shock mat, and the building. The model results were validated using an analytical solution reported in the literature. The performance of shock mats was examined by an extensive parametric analysis on the soil type, bedding modulus of shock mat and dominant excitation frequency. The results obtained indicated that although the shock mat can substantially reduce the building vibrations, its performance is significantly influenced by its underneath soil media. The softer the soil, the lower the shock mat efficiency. Also, as the train excitation frequency increases, a better performance of shock-mats is observed. A simplified model/method was developed for prediction of shock mat effectiveness in reduction of railway-induced vibrations, making use of the results obtained.

Throughout the previous years, many efforts focused on incorporating non-biodegradable wastes as a partial replacement and sustainable alternative for natural aggregates in cement-based materials. Currently, rubberized concrete is considered one of the most important green concrete materials produced by replacing natural aggregates with rubber particles from old tires in a concrete mixture. The main benefits of this material, in addition to its importance in sustainability and waste management, comes from the ability of rubber to considerably damp vibrations, which, when used in reinforced concrete structures, can significantly enhance its energy dissipation and vibration behavior. Nowadays, the literature has many experimental findings that provide an interesting view of rubberized concrete's dynamic behavior. On the other hand, it still lacks research that collects, interprets, and numerically investigates these findings to provide some correlations and construct reliable prediction models for rubberized concrete's dynamic properties. Therefore, this study is intended to propose prediction approaches for the dynamic properties of rubberized concrete. As a part of the study, multiple linear regression and artificial neural networks will be used to create prediction models for dynamic modulus of elasticity, damping ratio, and natural frequency.
