Object : In the present study, we investigated the obesity and blood parameters between Qi-deficiency and Fire/Heat pattern identification/syndrome differentiation (PI/SD) in acute stroke patients. Materials and Methods : A total of 391 stroke patients within 7 days after onset were consecutively recruited from 12 hospitals across South Korea from Nov. 1st, 2006 to Jun. 31st, 2009. They were diagnosed as Fire/Heat or Qi-deficiency among five PI/SD subtypes by two independent stroke experts. We investigated the differences of obesity and blood characteristics between Fire/Heat and Qi-deficiency by statistical analyses. Results : In male subjects, obesity was significantly associated with Fire/Heat PI/SD. The averaged mean BMI ($24.13kg/m^2$) and waist circumference(89.34cm) of the Fire/Heat group were higher than those of the Qi-deficiency group ($22.60kg/m^2$ and 83.43 cm, respectively). The number of obese patients was larger in the Fire/Heat group than in the Qi-deficiency group (p = 0.001). Hyperlipidemia was also related with Fire/Heat. However, obesity was not associated with PI/SD in female subjects where the number of hyperlipidemic patients was higher in the Qi-deficiency group. Among blood parameters, the levels of triglycerides and fasting blood sugar were higher in the Fire/Heat group compared with the Qi-deficiency group in male subjects. However, total cholesterol of the Qi-deficiency group was higher than in the Fire/Heat group among female subjects. Conclusion : This study shows that obesity and hyperlipidemia are significantly difference between Qi-deficiency and Fire/Heat. We suggests that PI/SD may be associated with clinical characteristics and large population study between PI/SD and clinical characteristics including blood parameters are needed.

We examined the relationship between the basic characteristics and types of leisure activities according to blood types. It was based on questionnaires answered by 441 collegians in public health departments and 282 in non-public health departments in Daegu Health College in March, 2005. The frequency of leisure activity of once or twice a week or less during weekdays was the most common.: The most common frequencies for all blood types were between 1 and 2 hours on weekdays and between 3 and 5 hours on the weekends or holidays. As far as the type of leisure activities during the weekdays was concerned, in the case of public health departments, blood type A was interested in computer games and then watching TV, blood type B was attracted to watching TV and listening to music, blood type AB was into watching TV, computer games, and listening to music, and blood type O was keen on watching TV and computer games in that order. The type of leisure activity according to blood types in public health departments was shown to be significantly different (p<0.05). The type of future leisure activity was shown to be significantly different between public health departments and non-public health departments (p<0.05). The type of present leisure activity preferred by collegians, according to the study, was entertainment such as computer games for most blood types. The type of future leisure activities was related to the field of tourism and sports. The collegians need to have more advanced and positive leisure activities.

Among non-invasive blood glucose detection technologies, the optical technique is a method that uses light reflection, absorption, and scattering characteristics when passing through a biological medium. It reduces pain or discomfort in measurement and has no risk of infection. So it is becoming a major flow of blood glucose detection research. Among them, near-infrared spectroscopy has a disadvantage in that the complexity increases when analyzing signals detected due to interferences between proteins and acids that share a similar absorption function with blood glucose molecules. In this study, a non-invasive sensor system with multiple near-infrared bands was designed and manufactured to alleviate the deterioration of blood glucose detection function that may occur due to skin absorption of near-infrared rays. A blood survey was conducted to verify the system, and the degree of blood glucose response in the blood was collected as spectral data, and the results of this study were quantitatively verified in terms of correlation between the data and blood glucose.

This paper presents a structural analysis on the rigid and deformed motion of the leaflet induced by the blood flow required in the design of a bileaflet mechanical heart valve (MHV) prosthesis. In the study on the design and the mechanical characteristics of a bileaflet mechanical heart valve, the fluid mechanics analysis on the blood flow passing through leaflets, the kinetodynamics analysis on the rigid body motion of the leaflet induced by the pulsatile blood flow, and the structural mechanics analysis on the deformed motion of the leaflet are required sequentially and simultaneously. Fluid forces computed in the previous hemodynamics analysis on the blood flow are used in the kinetodynamics analysis on the rigid body motion of the leaflet. Thereafter, the structural mechanics analysis on the deformed motion of the leaflet follows to predict the structural strength variation of the leaflet as the leaflet thickness changes. Analysis results show that structural deformations and stresses increase as the fluid pressure increases and the leaflet thickness decreases. Analysis results also show that the leaflet becomes structurally weaker and weaker as the leaflet thickness becomes smaller than 0.6 mm.

The purpose of this study was to investigate the anthropometric and blood biochemical characteristics, the dietary behaviors and health-related lifestyles of obese children in Incheon. A cross-sectional survey was conducted using anthropometric measurements, biochemical assessments and questionnaire analysis. The subjects included 7,055 obese children residing in the Incheon area (from 106 elementary schools). The degree of obesity was classified using the Obesity Index (OI) as light 20% ＜ OI ＜ 30% ; Medium 30% ＜ OI ＜ 50% ; Severe 50% ＞ OI. The statistical analysis was conducted using SPSS 10.0 program. Most subjects fell within the medium range of obesity. Most subjects had dietary problems such as overeating, unbalanced meals and skipping breakfast. The ratio of boy subjects eating green and yellow vegetables was lowe. when compared to that of the girl subjects. The boy subjects exercised more frequently and longer than the girls. As the Obesity Index increased, hypercholesterolemia significantly increased. The blood cholesterol levels of the subjects were positively correlated with body fat, waist/hip ratio and BMI; HDL cholesterol levels of the subjects were negatively correlated with the anthropometric data and the LDL cholesterol levels of the subjects were positively correlated with body fat. The blood triglycerides levels of the subjects were positively correlated with body weight, body fat, waist/hip ratio and BMI. Therefore, proper nutritional education and intervention are required for an improvement of obese children＇s dietary behavior, heath-related factors and blood lipid profiles.

This study was conducted to investigate effects of different levels of seleniferous whole crop barley (WCB) supplementation on performance, and blood characteristics as physiological responses in growing pigs. A total of 20 cross-bred pigs ((Landrace ${\times}$ Yorkshire) ${\times}$ Duroc) were divided into 4 treatments of 5 pigs each and experimental period lasted for 6 weeks. They were fed diets containing 0.1 (non-seleniferous WCB as controls), 0.2, 0.4, and 0.6 mg/kg levels of selenium (Se) by supplementing seleniferous WCB, and non-seleniferous or seleniferous WCB was formulated to 5% level in total ration. The diets were isonitrogenous (18% crude protein) and isocaloric (3,500 kcal/kg digestible energy) across treatments. Increasing levels of seleniferous WCB supplements did not affect feed intake and BW gain, and blood total protein concentration was (p<0.05) significantly higher for 0.2 mg/kg Se treatments than for controls. On d 14, blood albumin concentration was higher (p<0.05) for seleniferous WCB supplemented groups than for control group. Contrarily, blood glucose concentration was tended to be higher for controls than for seleniferous WCB groups. Blood total lipid concentration was significantly (p<0.05) lowered with increasing levels of seleniferous WCB. Serum glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase did not have any difference among treatments. It was tended that blood total cholesterol and triglyceride were lowered with increasing levels of seleniferous WCB. Blood Se concentration was significantly (p<0.05) increased with increasing levels of seleniferous WCB. The results indicate that Se present in seleniferous WCB had favorable effects on blood characteristics and blood Se increased by supplementing seleniferous WCB implies not only a good intestinal absorption of Se present in WCB but also the possibility of Se transfer into tissues.
