Objectives: To study symptom differentiation for yang deficiency and blood heat based on 117 psoriasis patients. Methods: Obtained frequency analysis (%), mean (%), and OR, CL(P-value) with prospective pre-post intervention design and multiple regression analysis. Results: There were no statistically significant differences as to sex, BMI, smoking and marital status, but there were statistically significant differences in variables of average age, family history, and alcohol consumption (P<0.05). There were no statistically significant differences in psoriasis symptoms as to initial age of onset, morbidity span, area of the initial onset, and the progression of psoriasis during the last three months of each patient. However, the type of psoriasis showed a statistically significant difference (p=0.011). While there were no statistically significant differences as to common cold, condition of psoriasis after recovering from the cold, skin condition, exercise, and seasonality, irregular perspiration showed significant difference (p<0.00). When confounding factors have been controlled the blood heat patient group as the comparison group, multiple regression analysis showed OR, CI(95%) of 1.06(0.31-3.63) for men, 0.28(0.08-1.06) for aged 30 to 49,0 and 0.18(0.04-0.80) for aged 50 and older. it was 0.06(0.01-0.7) for family history, 1.06(0.29-3.88) for drink alcohol, 19.90(2.53-156.7) for seasonality, and 10.28 (3.19-33.11) for perspiration problems. In these variables, Sex, age, smoking, and alcohol consumption showed no statistically significant results, but family history(p=0.049), seasonality(p=0.005), and irregular perspiration (p=0.017) were statistically significant. Conclusion: Family history, seasonality and irregular perspiration are the determining factors for yang deficiency and blood heat in psoriasis.

This study examined the water absorption and drying properties of the thirteen types of the knitted fabrics for sports wear. These physical properties were analysed with relation to the constituent fiber cross-sectional shape and structure parameters of the knitted fabrics by regression analysis. Absorption and drying properties of the knitted fabric specimens were increased with increasing the porosity of the constituent yarns, which was attributed to the capillary channels in the yarns. The water absorption and drying properties were increased and decreased with increasing tightness factor and stitch density of the knitted fabric. The absorption property of the knitted fabric for perspiration absorption and fast dry sport-wear clothing was mostly influenced mostly by fiber cross-sectional shape and its characteristics, whereas, drying property was dependent on the structural parameters of the knitted fabric such as tightness factor and stitch density. Therefore, superior perspiration absorption and fast drying knitted fabric could be obtained in the fabric structure with optimum tightness factor and stitch density, and constituent yarn structure with non-circular fiber crosssection and high porosity. GATS method and MMT method are used to measure sweating fast drying properties and it is necessary to carry out studies using these measurement methods in order to compare with the results of this study.

Many of the diseases that occur in a life being are either closely related to water, or they occur by loss or deterioration of water metabolism. There are six parts of study on this subject in ${\ulcorner}$Dongeubogam${\lrcorner}$. The parts are, the part of Jinaek the part of Dameum the part of Sobyeon the part of Bujong the part of Changman and the part of Seub. In these parts, it mentions loss of perspiration, abnormal urination, edema, abdominal dropsy, formation of abnormal body fluid and intrusion of dampness into the body and etc as the abnormal water metabolism. Loss of perspiration and urination is a process of eliminating the dampness in the body. Perspiration would be the abnormality of yanghwa[陽化]. Urination would be the loss of eumhwa[陰化]. Eum[飮] is the fluid accumulated in the body that failed to go through the process of Cihwa[氣化]. Dam[痰] is formed when the body fluid is heated by the smoking-fire. Meanwhile, the dampness occurs when the water penetrates into the bones, muscles and joints. Edema and abdominal dropsy are both outcomes of accumulated body fluid. Edema is the liquified body fluid congested on the surface or the peripheral ends of the body. Abdominal dropsy is congestion of fluid, that lost the characteristic of blood due to blood deterioration, in the abdominal part.

The water vapour permeability of clothing materials is a critical property for clothing systems that must maintain thermal equilibrium for the wearer. The evaporation of perspiration provides the means of cooling the human body. The perspiration should evaporate from the surface of the skin and pass as water vapour through the clothing, which must be permeable for comfort. The primary objectives in this study of the transfer through fabrics of water vapour are to measure this property in a quantitative manner appropriate to clothing systems and to provide an increased understanding of various types of fabric in water vapour transfer.
