Purpose: The purpose was to investigate the physiological parameters and health perception of adults in Kyungi province area, and the correlation between these variables. The subjects were 95 adults who participated voluntarily in the health examination program. Methods: The instruments for this study were physiological parameters, which were composed of blood pressure, blood sugar, and body fat. The health perception scale developed by Ware (1976), and the health practice performance scale developed by Chang et al. (1999). Results: The average blood pressure was 137/85mmHg, the average blood sugar was 108.56mg/dl, and the average body fat arm sunt was 27.08% in males, and 30.07% in females. There were significant negative correlation between health perception and blood sugar (r=-2.36, p=.01), and body fat (r= -2.77, p=.001). There were significant positive correlations between blood pressure and health behavior (r=2.76, p=.001). However a significant correlation between health perception and health behavior was not found. Of the sociodemographic characteristics, sex (F=5.42, p=.01), and marital status (F=3.29, p=.04) were related to blood pressure. Also sex (F=4.17, p=.04) was related to body fat, and sex (t=4.04, p=.03) was related to health perception and disease status (t=4.33, p=.040). Thus having a relationship with health behavior. Conclusion: It is suggested that health perception provide important information about health status. However, this study has not shown a correlation between health perception and health behavior. Therefore further research is needed to find the other variables related to health behavior.

Slaughterhouse blood is a by-product of animal slaughter that can be a good source of animal protein. This research purposed to examine the functional qualities of the blood plasma from Hanwoo cattle, black goat, and their hydrolysates. Part of the plasma was hydrolyzed with proteolytic enzymes (Bacillus protease, papain, thermolysin, elastase, and α-chymotrypsin) to yield bioactive peptides under optimum conditions. The levels of hydrolysates were evaluated by 15% sodium dodecyl sulfate polyacrylamide gel electrophoresis. The antioxidant, metal-chelating, and angiotensin I-converting enzyme (ACE) inhibitory properties of intact blood plasma and selected hydrolysates were investigated. Accordingly, two plasma hydrolysates by protease (pH 6.5/55℃/3 h) and thermolysin (pH 7.5/37℃/3-6 h) were selected for analysis of their functional properties. In the oil model system, only goat blood plasma had lower levels of thiobarbituric acid reactive substances than the control. The diphenyl picrylhydrazyl radical scavenging activity was higher in cattle and goat plasma than in proteolytic hydrolysates. Ironchelating activities increased after proteolytic degradation except for protease-treated cattle blood. Copper-chelating activity was excellent in all test samples except for the original bovine plasma. As for ACE inhibition, only non-hydrolyzed goat plasma and its hydrolysates by thermolysin showed ACE inhibitory activity (9.86±5.03% and 21.77±3.74%). In conclusion, goat plasma without hydrolyzation and its hydrolysates can be a good source of bioactive compounds with functional characteristics, whereas cattle plasma has a relatively low value. Further studies on the molecular structure of these compounds are needed with more suitable enzyme combinations.

The aim of this study was to investigate physicochemical properties of porcine blood hydrolyzed by proteases under various conditions for utilization as a food source. Five kinds of proteases (Alcalase, Neutrase, Protex-40L, PTPF-1430, and KMFP-15) were tested at different concentrations (0.1, 0.2, and 0.3%, w/v) during hydrolysis at 55 for 4 hr. Hydrolysis with $^{\circ}C$ KMFP-15 showed the lowest pH by 7.3. The highest soluble solid ($24.3^{\circ}Brix$) and free amino acid (4,944 mg%) contents were obtained by hydrolysis with KMFP-15 (w/v) at 0.2% addition level, which was not significantly different from the sample hydrolyzed at 0.3% level. Under the optimal condition of KMFP-15 at 0.2%, porcine blood was hydrolyzed at 60 up to 8 hr. The $^{\circ}C$ free amino acid content reached the highest at 4 hr, and then decreased with longer hydrolysis time. Under the optimal hydrolysis conditions, porcine blood hydrolysis powder had plenty of crude proteins, amino acids, and minerals, including iron, potassium, and zinc. The results showed that porcine blood could be utilized as an useful source of food supplement. The optimum conditions of hydrolyzing porcine blood, using 0.2 KMFP at $60^{\circ}C$ for 4 hr, can be used in the commercial production of protein supplements, amino acid sources, and iron fortifying agents.

Catheters are used to measure translesional pressure gradients in the stenosed coronary arteries. Catheter insertions during coronary angioplasty cause flow obstructions. A narrowed flow cross section with catheter present effectively introduced a tighter stenosis than the enlarged residual stenoses after balloon angiplasty. In general, the form of stenoses are no uniform. Sometimes, these are occurred the irregularly eccentricity If the analyses are conducted for uniform stenosed artery, the results will be underestimated. Thus, in this study, three dimensional computer simulations are conducted to investigate the flow blockage effects due to the catheter insertion during the coronary angioplasty. The results for the eccentric stenosed artery are compared with those of the concentric stenosed artery.

This article described the numerical investigation of shear-thinning blood flow characteristics when subjected to longitudinal and transverse vibrations and delineated the underlying mechanisms of the flow rate enhancements, respectively. In order to fully consider the mechanical vibrations of the capillary, a moving wall boundary condition was adopted. The present numerical results showed that the longitudinal vibration caused a significant increase of wall shear rates, which resulted in a decrease of viscosity and the subsequent increase of flow rates. However, the shear rate for the transverse vibration was slightly increased and the calculated flow rate was underestimated comparing with the previous experimental results.

The main objective of present study is to obtain information for flow characteristics, such as velocity and wall shear stress, of bifurcation in blood vessel. Branch flows for Newtonian fluids are simulated by using Fluent V.6.0. The numerical simulations are carried out for five cases divided by different values of bifurcation angle and area ratio. As a result of simulation, high wall shear stress is appeared at the bifurcated region. As increasing bifurcation angle, pressure drop is increasing. In addition, as the area is decreasing, pressure drop and wall shear stress is increasing.

This study was conducted to evaluate the effects of dietary vitamin levels and stocking densities on growth performance, nutrient digestibility, and blood characteristics in growing pigs. A $2{\times}3$ factorial (two vitamin levels, three regimens of stocking densities) arrangement was utilized with 96 pigs ($23.10{\pm}0.95$ kg initial body weight and 63 d of age) for 36 d. The pigs were allocated to pens with different stocking density (0.64, 0.48, and 0.38 $m^2/pig$, respectively). The diets used in this study were a normal diet (based on NRC) and a high level of vitamin diet (2-fold higher than normal diet). The ADG and ADFI of pigs were decreased as the stocking density increased (p = 0.03 and p = 0.01, respectively). The G/F of pigs was 5% lower in the high vitamin treatment (p = 0.03) as compared with the control treatment. The apparent total tract digestibility (ATTD) of DM and N digestibility was negatively affected by the high level of vitamin in diets (p = 0.05 and p = 0.04, respectively). Moreover, a significant and negative effect on the ATTD of N was detected in the large groups (linear, p = 0.02). Blood cortisol concentration was increased with increasing stocking density (linear, p = 0.05), and was decreased by high level of vitamin (p = 0.04) at the end of this experiment. Stocking density also caused a linear reduction in WBC concentration (p = 0.05). Our data indicated that the principal effect of stocking density was not reliant on dietary vitamin levels. In conclusion, results indicated that doubling the vitamin supplementation did not improve the growth performance of pigs in high density. However, the blood cortisol concentration was decreased but the ATTD of N digestibility was impaired by high level of vitamin diet.

A total of 144 pigs ((Landrace${\times}$Yorkshire)${\times}$Duroc)] with an average initial BW of $8.45{\pm}0.57$ kg were used in a 5-wk growth trial. Pigs were randomly allocated to 4 treatments with 9 replications per pen in a randomized complex block design. Dietary treatments included: i) CON (basal diet), ii) ANT (CON+tylosin 1 g/kg), iii) H1 (CON+H. cordata 1 g/kg) and iv) T1 (CON+T. officinale 1 g/kg). In this study, pigs fed the ANT and T1 treatment had a higher (p<0.05) average daily gain (ADG) and gain:feed (G:F) ratio than those fed CON and H1 treatment. Dietary ANT and T1 treatment led to a higher energy digestibility than the CON group. No difference (p>0.05) was observed on the growth performance and apparent total tract digestibility with H1 supplementation compared with the CON treatment. The inclusion of ANT treatment led to a higher (p<0.05) lymphocyte concentration compared with the CON treatment. Dietary supplementation of herbs did not affect (p>0.05) the blood characteristics (white blood cell (WBC), red blood cell (RBC), IgG, lymphocyte). No difference was observed on (p<0.05) fecal microbial shedding (E. coli and lactobacillus) between ANT and CON groups. Treatments H1 and T1 reduced the fecal E. coli concentration compared with the CON treatment, whereas the fecal lactobacillus concentration was not affected by the herb supplementation (p>0.05). In conclusion, the inclusion of T. officinale (1 g/kg) increased growth performance, feed efficiency, energy digestibility similarly to the antibiotic treatment. Dietary supplementation of T. officinale and H. cordata (1 g/kg) reduced the fecal E. coli concentration in weaning pigs.
