Purpose: This study was performed to evaluate effects of a stim-up matt walking exercise program on balance and gait of the frail elderly. Methods: A total of 37 elderly people recruited from S city were randomly assigned to the experimental group (n=22) and control group (n=15). The stim-up matt walking exercise program was offered twice a week for 8 weeks. Data were analyzed by SPSS 21.0. Results: The dynamic balance ability Timed Up and Go test of the experimental group was significantly faster than that of the control group (t=21.72, p<.001). The static balance ability open-eye standing test (t=44.15, p<.001) and close-eye standing test (t=9.01, p=.005) also showed increase in effects of the experimental group. In the walking ability, gait cycle (t=2.48, p=.018), cadence (t=-2.21, p=.034) and gait speed (t=-2.78, p=.009), positive effects were on. However, no statistically significant differences were found in stride length and double support. At the ankle joint range left ankle plantar flexion (t=3.92, p<.001) and left ankle dorsal flexion (t=4.51, p<.001) were higher in the experimental group than in the control group, and also right ankle plantar flexion (t=2.79, p=.008) and right ankle dorsal flexion (t=2.92, p=.006) increased in the experimental group. Conclusion: The significance of this study is that the stim-up matt walking exercise program for the frail elderly proves to be useful for improving balance and walking.

Objective: This study was conducted to investigate the effects of rumen-protected biotin (RPB) on growth performance, nutrient digestibility, nitrogen utilization and plasma biochemical parameters of Liaoning cashmere goats during the cashmere fiber growing period. Methods: Sixteen 6-month-old Liaoning cashmere twin-doelings (24.8±1.20 kg) were allocated to 2 diet groups that were individually ad libitum fed 30% concentrate and 70% forage diet (dry matter [DM]) by a paired experimental design. Goats of the control group were fed the basal diet, while goats belonging to the RPB group were fed the basal diet with 10 mg RPB/d per animal. The duration of the experiment was 16 weeks with two 8-week periods. Digestibility was determined at weeks 7 and 15, and other measures were taken every four weeks. Results: Compared with the control group, the average daily gain of the RPB group increased by 10.94% (p<0.05), and the intake of neutral detergent fiber was increased (p = 0.045). There were some increasing tendencies for the intake of DM, acid detergent fiber and ether extract (p = 0.070, 0.088, and 0.070, respectively). The intake and digestibility of N tended to increase (p = 0.062 and 0.093, respectively), while the N fecal excretion percentage of N intake was decreased (p = 0.093) in the RPB compared with the control group. N retention tended to increase (p = 0.084) with the addition of adding RPB to the diet. Plasma total protein was increased (p = 0.037), whereas the urea-N concentration was decreased (p = 0.049) in the RPB diet group compared with the control diet group. The levels of propionyl-CoA carboxylase (p<0.001) and methylmalonyl-CoA (p = 0.013) were increased in the RPB group. Conclusion: Supplementation of rumen-protected biotin in the diet of cashmere goats can enhance the utilization of N and improve daily weight gain during cashmere fiber growing period.

Two experiments were conducted to evaluate the effects of calcium (Ca) levels in weanling pigs (Landrace × Yorkshire × Duroc). In experiment 1, one hundred and eighty weanling pigs were randomly allotted to one of the three treatments. The treatments were low (Ca 0.60% in phase 1 and 0.50% in phase 2), standard (Ca 0.72% in phase 1 and 0.66% in phase 2), and high (Ca 0.84% in phase 1 and 0.72% in phase 2). In experiment 2, hundred and forty weanling pigs were randomly assigned to one of four treatments differing in Ca levels (high and low) and sources (CaCl₂ and CaCO₃) in a 2 × 2 factorial arrangement. There were 10 pigs per replicate in both experiments, with 6 replicates in each treatment, and they were conducted in two phases (phase 1, days 0-14; phase 2, days 15-28). In experiment 1, body weight (BW), average daily gain (ADG), and growth to feed ratio (G/F) increased as the Ca level decreased (p < 0.05). P digestibility was higher in the low-Ca diet group than in the high-Ca diet group (p <0.05). In experiment 2, the final BW, ADG, and G/F increased in the CaCl₂ diet group compared with the case in the CaCO₃ diet group (p < 0.05). The digestibility of crude protein (CP), Ca, and P was higher in the CaCl₂ diet group than in the CaCO₃ diet group (p < 0.05). Cl^- levels were higher in the CaCl₂ diet group than in the CaCO₃ diet group (p < 0.05). The bicarbonate (HCO_3-), base excess (BE), and electrolyte balance (EB) levels were lower in the CaCl₂ diet group than in the CaCO₃ diet group (p < 0.05). Hematocrit increased as the Ca level decreased (p < 0.05). The HCO_3- interacted with the Ca sources and thus, affected the Ca levels (p < 0.05). Bone ash, Ca, and P were downregulated in the low-Ca diet group compared with the case in the high-Ca diet group. Overall, the low dietary Ca supplementation led to greater growth performance. Furthermore, CaCl₂ appeared to be a better Ca source than CaCO₃ because of the greater digestibility of CP, Ca, and P, and improved EB.

To study the factors related to childhood obesity, 75 subjects were selected as an obese group and 75 subjects were selected as a control group according to their obesity index and BMI among the 583 children of 5th and 6th grade in elementary school in Seoul. For each subject, skinfold thickness was measured, information on the characteristics of family, nutrient intake and activity time of the subjects were obtained by questionnarie. The results were summarized as following: 1) Parents' obesity indices of obese group were significantly higher than those of control group(Father's Obesity Index : P<0.01, Mother's Obesity Index : P<0.05). 2) Questions about eating rate and behavior showed that subjects in obese group were significantly faster in their eating rate(p<0.05) and always more eager to eat food(p<0.001) compared to control group. 3) Dietary intake data showed that average daily intake of all the nutrients exceeded Korean recommended dietary allowances for the age group. In female children, fat intakes of obese group were significantly higher than control group(P<0.05). There was no such significant difference in male subjects. 4) Activity time record of subjects reveal that there was a trend for males to spend more time in moderate and high activity and less time in light activity compared to females. Subjects in obese group spent significantly more time for light activity(P<0.001) and significantly less time for moderate activity (P<0.001) compared to subjects in control group. The difference of activity was more pronounced in male subjects. 5) Correlation matrix of the variables showed that obesity index, BMI, and skinfold thickness of the subjects were highly correlated with each other. These indices were positively correlated to parent's obesity indices and the time spent for light activity, but negatively correlated to the time spent for moderate activity. Nutrient intakes were not significantly correlated to obesity indices. Form the results shown above, although both obese and control groups are from high socioeconomic class, obese children tended to come from family with fat parents. They eat fast and are always eager to eat. They tend to eat more fat but are very different from controls in nutrient intake. Obese children are significantly lower in their actinity compared to controls. So, for the prevention and treatment of childhood obesity, it seems to be more important to increase their activity levels.

Background: The rising prevalence of asthma may be associated with the rising prevalence of obesity in developed nations. There are several studies showing that obesity increases the risk of asthma in adults. We investigated the association of each body composition scale and bronchial hyper-responsiveness. Methods: This study involved a retrospective review of the existing records for 279 subjects with respiratory symptoms, who underwent a pulmonary function test, a methacholine challenge test and a body composition test between May 2007 and June 2009. Results: Of the 279 subjects, 179 (64%) were female. There was a statistically significant difference in fat free mass and in fat free mass index between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.036; p=0.000). There was no significant differences in body mass index, in fat mass and fat free mass index in the normal bronchial responsiveness group and bronchial hyper-responsiveness group in males. However in females, body mass index and fat free mass index were increased in the bronchial hyper-responsiveness group (p=0.044; p=0.000). Total body water (kg), fat free mass (kg) and soft lean mass (kg) were significantly different between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.002; p=0.000; p=0.000). Conclusion: This study showed significant differences in fat free mass and in fat free mass index between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. In females, BMI, soft lean mass, and total body water showed significant differences between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. We concluded that bronchial hyper-responsiveness was associated with not only body mass index but also fat free mass index in female bronchial asthma.
