This paper aims to present a model of obesity and leanness based on eum, yang, ki and blood metabolism of Korean medicine. I analyzed the theory of eum, yang, ki and blood metabolism, yang transforming ki and eum forming the body on Korean medicine, and compared them with energy homeostasis by anabolism and catabolism of modern medicine. In the eum and yang theory, the metabolic process of the human body is dominated by synergism and antagonism between eum force and yang force. When the balance of eum and yang collapses, all the pathological actions of the human body appear, and in the eum and yang metabolic process, an imbalance between yang transforming ki and eum forming the body occurs. The function of yang transforming ki is reduced to ki deficiency, and the function of eum forming the body is increased to blood excess. When blood excess and ki deficiency is given, energy intake increases, energy expenditure decreases, overweight and obesity occur. On the contrary, the function of yang transforming ki is increased to ki excess, and the function of eum forming the body is decreased to blood deficiency. When ki excess and blood deficiency is done, energy intake decreases and energy expenditure increases, the body becomes leanness. When the balance of eum, yang, ki and blood metabolism collapses and becomes blood excess and ki deficiency, overweight and obesity occur, and when ki excess and blood deficiency is done, the body becomes leanness. The energy homeostasis of the human body can be explained by eum, yang, ki and blood metabolism of Korean medicine and it contains the concept of anabolism and catabolism of modern medicine.

Objectives : This study aimed to evaluate the characteristics of acute stroke patients between excess syndrome and deficiency syndrome groups. Method : We recruited stroke patients from the patients admitted to the Department of Internal Medicine of Kyunghee University Oriental Medical Center, Dongguk University Ilsan Oriental Medical Center, Kyungwon University Songpa Oriental Medical Center and Kyungwon University Incheon Oriental Medical Center from April 2007 to August 2008. We diagnosed acute stroke patients as either excess syndrome or deficiency syndrome and analyzed their characteristics for type of stroke, blood test result. Sasang constitution and lifestyle. Result : We found height, weight, BMI, W/H ratio, hypertension, diabetes, migraine, silent infarction, TG, total lipid, HDL-chol, RBC, Hb, hematocrit, alcohol, smoking and Sasang constitution (Tae-eum, So-yang) were more associated with the excess syndrome group. And we found sea food and Sasang constitution(So-eum) was more associated with the deficiency syndrome group. Conclusion : According to the analysis, we found that the excess syndrome group had more risk factors than the deficiency syndrome group. These results could be utilized in the future as a basis material for Oriental medicine therapy. Further studies will be needed to better understand the differences between excess syndrome and deficiency syndrome groups among acute stroke patients.

In order to study electric properties of (Pb$\_$0.9/La$\_$0.1/)Ti$\_$0.975/O$_3$(PLT (10)) films with varying excess lead concentration (7.5, 10, 12.5, 15 ㏖% excess lead), the PLT films were deposited by sol-gel process. DTA analyses reveal that the crystallization temperature of the precursor powers decreased with increasing amount of excess lead. XRD patterns of PLT reveal pure perovskite structure and the preferred orientation increased with increasing Pb content in the films. With increasing amount of excess P$\_$b/, the relative permittivity ($\xi$$\_$r/) increased and leakage current density at 100 ㎸/cm transformed 4.01$\times$10$\^$-5/, 2.42$\times$10$\^$-6/, 1.27$\times$10$\^$-6/, 1.56$\times$10$\^$-6/A/㎠ respectively. In the results of hysteresis loops measured at 166 kV/cm, the remanent polarization (P$\_$r/) and the coercive field (E$\_$c) are 6.36$\mu$C/cm and 58.7 ㎸/cm, respectively (at 12.5 ㏖% excess P$\_$b/) With increasing amount of excess Pb, the remanent polarization for PLT thin film degraded to about 44%, 27%, 15%, 16% of the initial value after 10$\^$9/ cycles./TEX>) With increasing amount of excess Pb, the remanent polarization for PLT thin film degraded to about 44%, 27%, 15%, 16% of the initial value after $10^{9}$ cycles.

The present study was an attempt to investigate the effect of forskolin on secretion of catecholamines (CA) evoked by Ach, excess $K^+$, DMPP, McN-A-343 and caffeine from the isolated perfused rat adrenal glands and to elucidate its mechanism of action. The perfusion with forskolin (1.0 uM) for 1 min into the adrenal vein enhanced markedly the secreation of CA evoked by Ach (50 ug), excess $K^+$ (56 mM) DMPP (100 uM) and by caffeine (0.3 mM) but did not that by McN-A-343. Forskolin alone did not potentiate the CA secretion. Moreover, forskolin augmented the CA release evoked by the above same stimulation even in the absence of extracellular calcium. The 1 min perfusion of 300 uM-dibutyryl cyclic AMP (DBcAMP), which is known to increase cyclic AMP levels, led to enhancement of Ca secretion evoked by Ach, excess $K^+$ and DMPP but did not that by McN-A-343 and caffeine. DBcAMP by itself also did not augment the CA secretion. In the calcium-free medium DBcAMP significantly enhanced the CA secretion by the same stimulation, except for the case of McN-A-343. These experimental results suggest that forskolin activates adenylate cyclase, resulting the elevation of cyclic AMP which may potentiate cholinergic nicotinic receptor-mediated and also depolarization-dependent CA secretion and that it may alter the intracellular calcium homeostasis in the rat adrenal glands.

The allocation to third parties in increase of capital is increasing in KOSDAQ firms. With this trend, they cause many problems which involves stock price manipulation. Under this condition, this study analyzes stock price reaction by event study to 197 cases of 81 KOSDAQ companies that allocated to third parties in increase of capital between the year of 2007 and 2009. And we find determinants of cumulative abnormal return by using multiple regression. Results of this research are as follows. First, in case of excess return of (-5, +5), it reveals positive excess return significantly at 1% significance level during 4 days before payment day(event day). But it reveals negative excess return significantly at 1% significance level during 5 days after payment day. Second, in case of excess return of (-40, +40), it reveals positive excess return significantly at 1% significance level during 40 days before payment day(event day). But it reveals negative excess return significantly at 1% significance level during 40 days after payment day. Third, in case of excess return of (0, 1 year), it reveals negative excess return significantly at 1% significance level during 1 year after payment day. Fourth, significant determinant of cumulative abnormal return to (-5, +5) was firm size with positive effect. Significant determinants of cumulative abnormal return to (-40, +40) were reserve ratio and debt ratio. Reserve ratio has positive effect But debt ratio has negative effect. Significant determinants of cumulative abnormal return to (0, 1 year) were firm size, debt ratio, reserve ratio. equity ratio to large shareholder. Firm size, debt ratio, equity ratio to large shareholder have negative effect. But reserve ratio has positive effect.

This paper reports experimental excess molar volumes $V^E_m$ using a digital vibrating-tube densimeter and excess molar enthalpies $H^E_m$ by means of an isothermal microcalorimeter with a flow mixing cell for the binary mixtures{1,2-dichloropropane + 2-(2-methoxyethoxy)ethanol} and {1,2-dichloropropane + 2-(2-ethoxyethoxy)ethanol} at 298.15 K under atmospheric pressure. All the $V^E_m$ and $H^E_m$ of the two binary mixtures showed S-shaped forms, being negative for poor and positive for rich 1,2-dichloropropane mole fractions. These show that the excess properties were shown to be negative deviation from ideality due to the strong self-association effect among 2-(2-alkoxyethoxy)ethanol molecules at an early stage of mixing, a relatively high energy then is needed to break hydrogen bonds of 2-(2-alkoxyethoxy)ethanol with an increase ofhalogenated hydrocarbon molecular at high mole fraction of 1,2-dichloropropane. The values of excess molar properties($V^E_m$ and $H^E_m$) were fitted by the Redlich-Kister equation using Nelder-Mead's simplex pattern search method. The Wilson, NRTL, and UNIQUAC models were used to correlate the $H^E_m$ values.

Phase equilibrium and dynamic behavior studies were performed in systems containing $C_{12}E_5$ nonionic surfactant solution and nonpolar hydrocarbon oil. The phase behavior result showed an oil-in-water(O/W) microemulsion(${\mu}E$) in equilibrium with excess oil phase at low temperatures and a water-in-oil(W/O) ${\mu}E$ in equilibrium with excess water phase at high temperatures. For intermediate temperatures a 3 phase region containing excess water, excess oil, and a middle-phase microemulsion was observed and the transition temperature was found to increase with an increase in the chain length of a hydrocarbon oil. Dynamic behavior at low temperatures showed that an oil drop size decreased linearly with time due to solubilization into micelles and the solubilization rate decreased with an increase in the chain length of a hydrocarbon oil. On the other hand, both spontaneous emulsification of water into oil phase and expansion of oil drop with time were observed because of diffusion of surfactant and water into oil phase. Under conditions of a 3 phase region including a middle-phase ${\mu}E$, both rapid solubilization and emulsification of oil into aqueous surfactant solution were found mainly due to the existence of ultra-low interfacial tension. Interfacial tensions were measured as a function of time for n-decane oil drops brought into contact with 1 wt% surfactant solution at $25^{\circ}C$. Both equilibrium interfacial tension and equilibration time were found to increase with an increase in the chain length of a hydrocarbon oil.

Objective: The aims of this study were to analyze the deficiency-excess pattern identification (虛實辨證) and compare it to the sputum cytokines of asthma patients. Method: 50 asthma patients who met the inclusion and exclusion criteria were included in this study. They were divided into two groups: deficiency and excess syndrome groups. Sputum examinations were performed including $TNF-{\alpha}$, Interleukin (IL)-4, IL-5, IL-10, and IL-13. The Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA), the Visual Analog Scale(VAS), and heart rate variability (HRV) were also measured. We also conducted laboratory tests, including the hematological indexes. Results: Based on the pattern identification, 50 asthma patients can be divided into two categories of groups: the deficiency syndrome group (N=24) and the excess syndrome group (N=26). In the analysis of sputum cytokines, although the $TNF-{\alpha}$, IL-4 and IL-13 were at a higher level in the deficient pattern group than in the excess pattern group, it was insignificantly different. There was a negative correlation in the analysis of QLQAKA and VAS. In the analysis of HRV, although the mean value of VLF, LF, and HF in the deficiency syndrome group was higher than in the excess syndrome group, it was insignificantly different. There was no significant difference in the hematological tests between the deficiency and the excess syndrome group. The mean value of the IgE in the blood tests was five times greater than the reference value. Conclusion: The cytokines of sputum including $TNF-{\alpha}$, IL-4, IL-5, IL-10, and IL-13 were indifferent statistically. Reinforcing the healthy and eliminating the pathogenic factors should be considered.

In this study, the effect of cosurfactant on the phase equilibrium and dynamic behavior was studied in systems containing NP7 nonionic surfactant solutions and nonpolar hydrocarbon oils. All cosurfactants used during this study such as n-pentanol, n-octanol and n-decanol acted as a hydrophobic additive and thus promoted the transition from an oil in water (O/W) microemulsion (${\mu}E$) in equilibrium with an excess oil phase to a three-phase region containing excess water, excess oil, and a middle-phase microemulsion and further to a water in oil (W/O) ${\mu}E$ in equilibrium with the excess water phase. The transition temperature was found to decrease with both increases in the chain length and amount of addition of a cosurfactant. Dynamic behavior studies under O/W ${\mu}E$ conditions showed that an oil drop size decreased with time due to the solubilization into micelles. On the other hand, both the spontaneous emulsification of water into the oil phase and the expansion of oil drop were observed under W/O ${\mu}E$ conditions because of the diffusion of surfactant and water into the oil phase. Under conditions of a three-phase region including a middle-phase ${\mu}E$, both the rapid solubilization and emulsification of the oil into aqueous solutions were found mainly due to the existence of ultra-low interfacial tension. Dynamic interfacial tension measurements have been found to be in a good agreement with dynamic behavior results.
