Experimental studies were done to know effect of insensible water loss of Hwangkitang(HKT) in mice. After administration of extract of HKT to the mice, changes of body temperature, body weight, serum Sodium and chloride ion was measured. And sametime, serum antibody to SRBC, delayed hypersensitivity and phagocytic activity of polymorphonuclear leukocytes(PMN) was measured to know immunologic effect. The results obtained as follows; 1. After exposure to $40^{\circ}C$ environment, increment of body temperature in treated group was slower than control group during first 40 minute, and no difference after 40 minute. 2. After exposured to $40^{\circ}C$ environment, decrement of body weight in treated group except administration group of 1.0g/kg extract of HKT was slower than control group during first 40 minute, and no difference after 40 minute. 3. After exposured to $40^{\circ}C$ environment, decrement of body weight in administration group of 4.0g/kg extract of HKT to mice was slower than control group during first 20 minute(p<0.005). 4. After exposure to $40^{\circ}C$ environment there was no stastical difference between treated group and control group in changes of serum sodium and chloride ion. 5. There was no statistical differences between treated group and control group in changes of serum antibody, delayed hypersensitivity and phagocytic activity of PMN.

Oryoungsan which first recorded in Sanghanron, the clinical medical book consists of treating acute febrile disease according to its change, is one of the frequently used oriental medicines. these days, it has been prescribed in symptoms accompanied by edema mostly. therefore it is easy to consider it as a type of diuretics. In Sanghanron it was originally used in the symptoms of perspiration, decreased urine volume, thirsty, flatulence. these symptoms indicate loss of body fluid and the prescription which orders "taking warm water sufficiently" supports this. On this background, it is supposed that Oryoungsan treats dehydration after providing water and electrolytes. To consider that herbal medicines consisted of Oryoungsan make electrolytes go out of the body, The healing mechanism of dehydration doesn't meet this. Because Oryoungsan was used in condition of fever or in similar condition, it is more resonable to understand that restoration of increasing blood flow to the subcutaneous venous plexus regulating body temperature in febrile condition into body circulation, resulting into maintaining main blood volume and into treating decreased urine volume and thirsty is Oryoungsan's function in the dehydration or febrile condition. That is, symptoms are decreased or disappeared through restoring unbalance of internal body fluid. The other target is pain controls, especially chronic headache, facial pain and trigeminal neuralgia. it is suggested that the function of pain control of Oryoungsan is related to 5-HT(5-hydroxytrypamine), nerve transmitter in the endogenous analgesic system. Moreover it is also suggested that Oryoungsan is relate to 5-HT, considering the fact that gastroparesis, a symptom of cyclic vomiting syndrome treated with 5-HT1D receptor agonist is similar to the 'bi', symptoms appeared in the Oryoungsan-related disease.

Objective : To suggest a scientific evidence of Aconitum carmichaeli Debx. (Aconiti Lateralis Radix Preparata: ALRP) as one of cooling and heating medicines on the regulation of body temperature, we investigated the effects of ALRP water extract on hypothyroidism. Methods : Hypothyroidism was induced by intradermal injection with PTU for 4 weeks in SD rats. ALRP extract or L-thyroxine as a control drug was orally administrated for 2 weeks with PTU injection in rats. The physiological and serological parameters were measured in rats. The histological change of thyroid tissues was observed by H&E staining, and also the expression of thermo-regulating proteins was determined by Western blot in dorsal root ganglia and brain tissues of rats. Results : The administration of ALRP extract in PTU-induced hypothyroidism rats was significantly increased body temperature, but did not changes on body weight, food and water intake. ALRP extract did not effect on the levels of TSH and T4 in the hypothyroidism rats. ALRP extract significantly decreased the levels of GPT, glucose, HDL-cholesterol, LDL-cholesterol, and total cholesterol in the hypothyroidism rats. In histological observation, the enlarged epithelium and atrophic follicles with higher concentration of follicular cells on hypothyroidism were improved by ALRP extract. In addition, ALRP extract increased the expression of TRPV1 and TRPM8 ion channel proteins in hypothyroidism rats. Conclusion : These results indicate that ALRP extract can improve PTU-induced hypothyroidism through regulation of body temperature and lipid accumulation. The action mechanism of ALRP extract is related with body temperature control by thermoregulation with TRP ion channels.

The occurrence of toxic cyanobacterial blooms has been reported worldwide and poses a threat to human health through drinking water exposure. The toxins they produce are highly water soluble and can leach into the water body. To eliminate any risk of drinking water exposure, removal of these toxins is essential before the water is consumed. Conventional water treatment techniques such as chlorination, if managed well, can be effectively used to remove some of these toxins, however, saxitoxin and its derivatives pose a problem. Little toxicological data are available to evaluate the real threat of these toxins.

Water is an essential ingredient to brew coffee. Mineral contents in the water can affect both water quality and taste quality of coffee. The effects of minerals in the water on sensory characteristics of coffee were investigated in different water samples (A: Arisu, B: Claris, C: Spring water, D: Samdasoo, E: Evian, Distilled water as control). Based on the results of quantitative descriptive analysis (QDA), there were statistically significant (p<0.01) in flavor, acidity, bitterness, sweetness, body and aftertaste according to different water samples used to brew coffee. The canonical correlation analysis of minerals (Ca, Mg, Na, K) and taste (acidity, bitterness, sweetness) indicated that there were highly correlated in the relationship between bitterness and Mg content. A strong negative relationship was shown between bitterness and acidity, sweetness. A result of preference test using hedonic scale showed an inverse linear relationship between taste quality and total mineral contents.

The purpose of this paper is to study the upstream waves in front of an advancing arbitrary hull shape in a restricted water channel. Conventionally, in a restricted water channel, shallow water effects are amplified because of the finite water depth and width. When the effects of shallow water and the restricted channel width are severe, upstream waves propagate forward from the fore-body of the advancing hull. In this study, numerical simulations are carried out for the relevant analysis of the flow phenomena by the draft variation of advancing hull in a restricted water channel. Numerical simulations are done with a finite-difference method based on the MAC scheme in a rectangular grid system.

Objectives : Evaluating water and its comparisons to Yin(陰) and Yang(陽). In this section, we will look into this matter from Dongeuibogam(東醫寶鑑) and introduce an oriental perspective on the subject of water(水部). Methods : Translating Eumchanboksikjeon(飮饌服食牋) from Junsangpaljeon(遵生八牋). An in depth study of related contents and comparing to the water section(水部) of Dongeuibogam(東醫寶鑑) Results : According to the section of Varieties of Teas and Water(茶泉類) in The Discussion of Springs(論泉水), Goryum(高濂) divided water into five different types in Eumchanboksikjeon(飮饌服食牋) of Junsangpaljeon(遵生八牋). These different types are Water that runs between rocks, Clear and cold water, Sweet and fragrant water, Spiritual water and Well water. Dongeuibogam(東醫寶鑑) also analyzed 28 different types of water out the 33 its list. The idea is that one must use water differently according its origins, where it originated, when and what season to maximize the usage of the water because the energy of water would be different. Conclusions : By evaluating water, we have learned that water picks up energy and changes according to its surrounding environments. The different types of water used changes the medicinal ingredients and it affects the human body differently. One must keep in mind, the cycles of water, its energy and how it helps us live a healthier life.
