The increasing area of abandoned rice fields could provide new opportunities for wetland restoration in Asia. However, it is unknown how quickly or completely abandoned rice fields will recover from agricultural disturbances. We assessed water quality and plant community succession in abandoned rice fields with different hydrology in a mountain valley to understand the effects of hydrological regime on recovery. Water level, soil redox potential, water quality, plant composition, and primary production were measured. The sites, coded as D6, N13, and N16, had been recovering for 6, 13, and 16 years by 2006. N13 and N16 have been recovering naturally whereas D6 has been drained with a nearby dike and was tilled in 2001. The typical hydroperiods of D6, N13, and N16 were no surface water, permanently flooded, and seasonally flooded, respectively. The major change in vegetation structure of both D6 and N13 was the replacement of herbaceous species by woody species. Drawdown accelerated this change because Salix koreensis grew better in damp conditions than in flooded conditions. Phragmites japonica reduced plot-level plant species richness. The removal efficiency of $NH_4-N$, $NO_3-N$, and $PO_4-P$ from water varied seasonally, ranging between -78.8 to 44.3%, 0 to 97.5%, and -26.0 to 44.4%, respectively. In summary, abandoned rice fields quickly became suitable habitat for native wetland plant species and improved regional water quality. Variation among our sites indicates that it is likely possible to manage abandoned rice fields, mostly through controlling hydrology, to achieve site-specific restoration goals.

Pruritus is [CHECK DEFN] itchy feeling of one's skin. We often face stroke patients who complain about Pruritus. They occasionally fail to fall asleep or have a secondary infection as a result of scratching. For these reasons, severe Pruritus brings down general condition and interferes with recovery. The causes of Pruritus are distributed to from skin diseases and from internal diseases. Especially among the skin diseases, Xerotic Eczema, which is called Senile Eczema causes the dry skin in the elderly, especially lower limb's extensor part. According to the epidemiology, 20% of the old have Xerotic Eczema. In oriental medicine, Pruritus is called Pungsoyang(風瘙痒), Pungyang(風痒), Yangpung(痒風), Sinyang(身痒). The cause of Pruritus is divided into two. One is endogenous factors and the other is exogenous factors. The former are deficiency of blood(血虛), blood fever(血熱), wind-heat due to internal damage(內傷風熱), damp-heat in the liver and gallbladder(肝膽濕熱), endogenous wind stirring in the liver(肝風內動), deticiency syndrome of the spleen(脾虛), deficiency of Yin of the liver and kidneys(肝腎陰虛) and deficiency of the Penetration and Conception Vessels(衝任不足). The latter are wind-cold due to exogenous affection(外感風寒) and wind-heat due to exogenous affection(外感風寒). We report two stroke patients who complained of severe Pruritus They were diagnosed as having Xerotic Eczema by a dermatologist. We regarded their Pruritus as blood fever(血熱) and wind-heat(風熱) and prescribed Sopung-San to these patients. These patients showed significant improvement.

Most of the cholesterol is synthesized by liver in the body while about one of third is taken via dietary. The main functions of cholesterol is to protect membranes in cell surface, avoid the arterial bleeding by hypertension, and prolong the life of erythrocytes, and so on. However, overload of cholesterol leads to arteriosclerosis associated with leading death cause. Lack of physical activity, emotional and environmental stress, and low intake of protein or vitamin E induce the unbalance between HDL- and LDL-cholesterol so become a basis of ischemic disorders in heart, brain and elsewhere in the body. So far, four major classes of medications for hyperlipidemia are HMG-CoA reductase inhibitors (statins), bile acid sequestrants, nicotinic acid, and fibric acids. The statins can lower LDL and levels triglyceride, but may induce myopathy and an elevation of liver enzyme levels. The bile acid sequestrants lower LDL levels and raise HDL levels with no effect on triglyceride levels but side effects of gastrointestinal (GI) distress, constipation, and a decrease in the absorption of other drugs. Nicotinic acid and fibric acids lower LDL and triglyceride levels with showing flushing, hyperglycemia, hyperuricemia, GI distress, and hepatotoxicity dyspepsia, gallstones, myopathy, and unexplained noncardiac death as adverse effects. Above western drugs lower cholesterol by 15 to 30% while all have notable adverse effects. In traditional medicine, hyperlipidemia is regarded as retention of phlegm and fluid disease. Etiology and pathogenesis of hyperlipidemia is basically based on Spleen-Deficiency and Phlegm-Stagnation, accumulation and stasis of -heat, and Qi & blood stagnation induced by Phlegm-damp, water-dampness, and blood stasis. Thereby, strengthening Spleen and dissolving Phlegm, clearing away heat and diuresis, and supplementing Qi and activating blood circulation are commonly used therapeutic methods for hyperlipidemia. The traditional herbal medicine, have been used for patients with CVA, hypertension or hyperlipidemia in Oriental hospital or Oriental clinic. The lock and key theory is used to develop most of western medicine, however many diseases are caused by mixed factors in body-complex system. We expect that Oriental pharmacological theory could be newborn as a novel drug showing high advantage of blood levels of lipidsand QOL of performance without side effects.

According to herbalogical bibligraphy and literature, therapeutic effects of Achyranthis Radix on arthritis was as follows, 1. Achyranthis Radix of Amaranthaceae is divided into five species-Achyranthes japonica, A. bidentata, A. longifolia, A. fauriei, Cyathula capitata, C. officialis and the characteristic, taste, channel entry, effects and main treatments were alike. 2. Winefrying stood for repairing treatement method for Achyranthis Radix Before repairing treatment method, Achyranthis Radix had three tastes(bitter, sour, and sweet) and calm and not poisoning characteristic. After repairing treatment method, the bitter taste was disappeared, and calm and not poisoning characteristic was changed into warm characteristic. 3. Effects of Achyranthis Radix were quicking the blood and dispelling stasis, liver-kidney supplement and strengthening musculo-skeletal system. Main treatments were relief of lumbar and knee joint pain, static menstrural block and wind-cold- damp impediment. 4. Contraindication of Achyranthis Radix was sympthom caused by spleen-kidney yang vacuity, upper burner disease and lower burner hemorrhage etc. Being used in pregnant woman, it could incur abortion. 5. Contraindication of Achyranthis Radix was beef, milk and mutton. It's fear was Radix Cynanchi Stauntonii and Semen Plantaginis. It's aversion was the firefly. Herba Taraxaci, Carapax Amydae, Carapax Testudinis and Radix Cynanchi Stauntonii. From above results, I suppose Achyranthis Radix has enough herbalogical foundation and could be used to treat arthritis and it is necessary to make a profound study of it.

Objective : This study was conducted to infer the effect of superficies-resolveing herbs by analyzing effect terms which have extracted and refined, based on four temperatures and five tastes. Method : Firstly, temperatures, tastes and effect terms were extracted from the 27 kinds of superficies-resolving herbs written in Herbology. Then, each effect terms was divided into single meaning term and refined as typical term, using the inclusive effect terms I established. After that, herbs were grouped by tastes and found the effect terms which are mentioned most frequently. And it could be supposed to be classified into each herb's new effects based on the relationship between properties and those effect terms. It is also inferred into new tastes from some herbs by analysing the representative effects group of each taste and finding which other tastes can be related to each herb's effect. Result & Conclusion : All the superficies-resolving herbs can have wind-dispelling effect and superficies-resolving effect, except Bulpleuri Radix. This herb is able to has just the wind-dispelling effect. And it's more appropriate to categorize Bulpleuri Radix to heat-clearing herb group than superficies-resolving herb group, considering its several, distinctly cold characteristics. Some effects are concentrated to wind-cold-dispersing herb group and others to wind-heat-dispersing herb group. Each tastes has its own representative effect group. And, according to its tastes' representative effect, some of herbs are reasonable to get new effect term. With not so feasible reason, 4 kinds of herbs are supposed to contain all of hot, bitter, and sweet tastes. Also It's needed to study much deeper whether Perillae Herba, Zingiberis Rhizoma Crudus and Elsholtziae Herba are belong to superficies-resolving herb group or to interior-warming or damp-dissolving aromatic herb group.

Methods: It was studied on the 47 kinds of oriental medical literature for fecal blood. Results: Fecal blood means bleeding with faces from anus and indicates all the three cases such as blooding before and after evacuation, evacuation of feces mixed with blood, and simple melena. The main causes are fire(火) and deficiency of spleen qi (脾氣虛). According to the color of fecal blood and the region of the bleeding, first, if the blood color is dark-red and blood discharges after emptying the bowels, it is called deposited poison into Jang(臟毒) or distant bleeding(遠血), and if the color of blood is clear and bowel emptying occurs after bleeding, it is bloody stool due to intestinal wind(腸風) or nearby bleeding(近血). For treating methods(治法). removing heat from the blood and stopping bleeding(淸熱凉血止血), removing dampness and stopping bleeding(淸熱除濕止血), invigorating Ki for promoting Hul-controJ(益氣攝血), warming the spleen and stomach to dispel cold and stopping bleeding(溫中散寒止血) etc are applied. As for the treating prescriptionl(治法), a Hwangtotang(黃土湯). Jeoksodudanggwitang(赤小豆當歸散). Gwihwasan(槐花散). Wipungtang(胃風湯). Hwangnyeonhwan modifying(黃連丸加減). Samultang modifying(四物湯加減). Paedoksan modifying(敗毒散加減) etc are used. As for acupuncture and moxibustion(鍼灸療法). if etiology(病因) is damp-heat(濕熱), acupuncture(刺鍼) at Janggang(長强); Charyo(BL 32); Sangeoheo(ST 37)(上巨虛); Seungsan(BL 57)(承山穴), and in case of deficiency of spleen Gi(脾氣虛), acupunture(刺鍼) with tonification(補法) at I Baek(EX-UE 2)(二白); Gwanwon(CC 4)(關元); Joksamni(ST 36)(足三里) Taebaek(SP 3)(太白); Hoeeum(CC 1)(會陰穴), or mxibuston(灸) at Baekoe(GC 2O)(百會); Myeongmun9GC (命門) or the point of opposite to umbilicus among spinal vertebrae(脊中對臍穴) are used. The external treatment(外治療法) was consisted of plastering umbilicus therapy(敷臍法) and enema therapy(灌腸法).

Hot Plate is the major unit that it used to remove damp of wafer surface, to strength adhesion of photoresist (PR) and to bake coated PR in FAB process of semiconductor. The badness of Hot Plate (HP) has directly influence upon the performance of wafer, it is necessary to guarantee the performance of HP. In this study, a reliability evaluation system has been designed and developed, which is to measure and to estimate thermal uniformity and flatness of HP in range of temperature 0~$250^\circC$. This system has included the techniques which measures and analyzes thermal uniformity using infrared thermal vision, and which compensates measuring error of flatness using laser displacement sensor For measuring flatness, a measurement stage of 3 axes are developed which adapts the precision encoder. The allowable error of this system in respect of thermal uniformity is less $than\pm0.1^\circC$ and in respect of flatness is less $than\pm$1mm . It is expected that the developed system can measure from $\Phi200mm\;(wafer 8＂)\;to\;\Phi300mm$ (wafer 12＂) and also can be used in performance test of the Cool Plate and industrial heater, etc.

The purpose of this study is to develop a method to spread out the ecological ponds in urban areas more effectively. It is urgent to supply the ecological ponds in more broad scope to ensure the water space in urban areas which has been dried out. It is necessary to formulate a plan for improving the amenity in the cities through creation a biotop in swampy land by building rainfall ponds. Thus, a model of the ecological pond in this study has been developed by reviewing the related researches which provide the theoretical basis and by considering the characteristics of nature for a naturally approached pond. This study has produced a ecological pond model in order to introduce and spread out damp biotop. Ecological aspects have been mainly considered in designing and building the pond model. This model consists of areas for emerged plants and bog plants and has its advantage in providing animals and insects with habitats and shelters. In addition, the model includes areas for emerged plants, which are very effective in purification of the rainfall from the rooftop. After the construction of the pond, the plants were planted according to the plan, and the infiltration trench was installed beside the pond to drain out the overflow of the pond. The result of this research has shown the possibility of supplying the ecological pond in small parks and in schools of the city in an easy way. Through the application of this pond system, the water cycle and the ecosystem in urban areas will be improved.

We report finding ways to improve the long-term reliability of PV module including the heterostructure with the intrinsic thin layer (HIT) solar cell. We point out the stability of the products of Panasonic HIT cell. We account for a brief description of the module manufacturing process to investigate the issues of each process and analyze the causes. We carried out the silicon PV module of the glass to glass type under the damp heat test around 1000 hours. However, it degraded around 7% of PV module power after 300 hours exposure in comparison with the initial status (Initial: 12.7 Watt). We investigated possible cause and solutions for the module performance to develop the long-term reliability.
