The physiological systems have nonlinear complex phenomena. Expecially, the flow of capillary blood vessel has a nonlinear dynamic system. Thus, this study analyzes nonlinear characteristics of the flow of capillary blood vessel in physiological systems using chaotic tools(phase space reconstruction, correlation dimension, largest lyapunov exponent). Experimental data have been acquired from examining 10 rabbits. The results of chaotic analysis showed a decreasing largest lyapunov exponent and correlation dimension according to increasement glocose index. And we also know the chaotic behavior.

Objective : To study of Literature on the Ying Qi and Wei Qi One of thing that is among basis theory of Oriental medicine is Vital Essence, Vitality, Qi and Blood(精神氣血) justly. Results : Physiological special quality of Ying Qi(營氣) first, flows within Blood Circulation and the temper is mild and second, transform blood and grow up whole body, and follow through Pectoral Qi(宗氣). Wei Qi(衛氣) means running regeneration of material that do guard action of human body as refined nutritious substances transformed in food. Physiological special quality of Wei Qi(衛氣) first, nature is fast, smooth, and sharp. And it flows outside Blood Circulation. Second, go on muscslar gap without following through Pectoral Qi(宗氣). Ying blood(營血) flows within Blood Circulation means living body ingredient which thing reveals by circulation of the blood change phenomenon. Ying Qi(營氣) is Ying(營) in meaning which go on meridians, therefore meridians as wandering living body reaction route mean. This Ying Qi(營氣)'s physiology transform blood and grows up whole body and flows within Blood Circulation. It becomes most important ingredient of composition of blood, Wei Qi(衛氣) transforms and becomes nutrition constantly by running regeneration of material which transform in Jungcho(中焦) and spread by spreading action of upper chest exhaust in lower belly above the blader of apriority, Kidney-yang.

Hemorheology plays an important role in atherosclerosis. Hemorheologic properties of blood include whole blood viscosity, plasma viscosity, hemaocrit, RBC deformability and aggregation, and fibrinogen concentration in plasma. Blood flow is determine by three parameters (pressure, lumen diameter, and whole blood viscosity), whole blood viscosity is one of the key physiological variables. However, the significance of whole blood viscosity has not yet not been fully appreciated. Whole blood viscosity has a unique property, non-Newtonian shear-thinning characteristics, which is primarily due to the presence of RBCs. Hence, RBC deformability and aggregation directly affect the magnitude of blood viscosity, and any factors or diseases affecting RBC characteristics influence blood viscosity. Therefore, on can see that whole blood viscosity is the causal mechanism by which traditional risk factors such as hypertension, hyperlipidemia, smoking, exercise, obesity, age, and gender are related to atherogenesis. In this regard, we included whole blood viscosity in the three key determinants of injurious pulsatile flow that results in mechanical injury and protective adaptation in the arterial system. Because whole blood viscosity is a potential predictor of cardiovascular diseases, it should be measured in routine cardiovascular profiles. Incorporating whole blood viscosity measurements into a standard clinical protocol could improve our ability to identify patients at risk for cardiovascular disease and its complications.

The purpose of this study is to observe clinically the effects of red onion prescription on type 2 diabetes. The subject of this study were middle-aged people. We measured clinically physiological index, body composition, radial arterial pulse wave before taking medicine and after taking medicine for 4 month (the prescription of red onion). The study results were as follows. In physiological Index, diastolic blood pressure(mmHg)(p<0.001), Fasting blood glucose(mg/dL)(p=0.001), and HbA1c(%)(p<0.001) were decreased significantly after taking medicine. In body Composition, waist-hip ratio(p=0.031), body fat percentage(p=0.006), fat mass(kg)(p=0.005), and muscle mass(kg)(p=0.001) were decreased significantly after taking medicine. Blood Circulation Index, ECO(L/min)(p=0.038) and ECI($L/min/m^2$)(p=0.007) were increased significantly after taking medicine, ECR($dyne^*sec^*cm^{-5}$)(p=0.002), and ECRI($dyne^*sec/cm$)(p=0.001) were decreased significantly after taking medicine for 4 month. The prescription of red onion was showed significant change in physiological index, character of body composition, blood circulation index. Based on this result, it is considered that red onion prescription has the positive effects on type 2 diabetes and blood circulation clinically. In the future, diversified studies on the effects of red onion prescription are needed.

In "Hwangjenaegyeong(黃帝內經)", the name of blood vessels is closely related to images of the river, and the word for blood vessel contains the following meaning, such as blood vessel, blood wind as well as blood stasis and so on. In a physiological perspective, the unobstructed blood vessel and normal operation blood are important symbols of health, for blood is the basis for human survival, physical activity and mental activity. In pathology, the external cold, excessive seven emotions and a biased diet can cause many kinds of abnormalities of the blood vessels, which can in turn become causes for a variety of diseases. The theory of blood vessels in "Hwangjenaegyeong" can provide guidance for diagnosis and treatment of cardiovascular diseases in practice.

The purpose of this study was to collect data of skin temperature and physiological responses which is useful for standardization of insulation measurement in various garments. And we investigated sex and season difference of physiological responses of 60's males and 60's females in hot and cold environment. Healthy ten 60's males and ten 60's females volunteered as subjects. The experiment was conducted three times; One for winter condition($5^{\circ}C$, 45%), another for summer condition($30^{\circ}C$, 65%) and the other for nude condition as control($30^{\circ}C$, 65%). The subjects were sitting for 1 hour with suitable ensemble on each experimental condition in climate chamber. We measured skin temperature, rectal temperature, heart rate, oxygen uptake, sweat rate, blood flow, blood pressure and subjective sensations. We found that skin temperature and most of physiological responses were higher in male subject, summer condition than in female subject, winter condition.

The purpose of this study was to investigate the effect of aromatherapy on pain level, blood pressure, pulse rate, sleep, anxiety and depression of patients with pain. This study used a non equivalent quasi-experimental design. Aromatherapy was the inhalation of blending oils with lavender, eucalyptus, peppermint for 3 weeks. As the estimation for the physiological aspect, the visual analogy scale (VAS) for the pain level, blood pressure and pulse rate were measured. Also, as the estimation for the psychological aspect, Sleep of Snyder-Halpern & Verra, anxiety of Spielbeger and depression of Beck were used. The data were analyzed by SAS program using $x^2$ test, Fisher's exact test, Cronbach ${\alpha}$ and t-test. The results of this study were as follows. Pain level(p=0.001), state anxiety(p=0.018), trait anxiety(p=0.002), and depression(p<0.001) improved significantly in the experimental group. Also, there was significant difference between the experimental group and the control group on the depression(p=0.012). Aromatherapy was effective in physiological and psychological therapy. Also it can be applied in combination with existing Oriental medical therapy.
