Present study was to investigate the effect of dietary vegetable sources such as carrot, peahull and squash on mineral balance of Na, K, Ca, Fe, Cu, Zn and Mg in mice. It would also determine if the kind, level and feeding period of vegetables can affect the mineral balance. One hundred and thirty mice weighing $29{\sim}30g$(8 weeks of age) were randomly selected. Ten mice were fed their standard diet, and the others were divided into three experimental groups that were fed standard diet supplemented with carrot, peahull and squash. Mineral intake and urinary and fecal excretion of minerals were measured to investigate the effect of the kind, level and feeding period of vegetables on absorption rate and balance of minerals. Body-weight gain was increased in high peahull diet group compared to the control. No significant difference was observed for feed efficiency ratios between different experimental groups and urine volume was increased by vegetable fed group. Na, Ca, Fe, and Cu intake were lower in high squash-diet fed soup. K intake was higher in carrot fed mice, and Zn, and Mg intake were higher in peahull fed mice. Absorption rate and balance of mineral in control group resulted in positive balance while experimental groups showed negative. The kind of vegetable, feeding level and feeding period affected the intake of Na, K, Ca, Cu and absorption rate of Cu, Zn and balance of K, Cu, Zn to negative. In spite of the higher intake of t Zn and Mg, in experimental groups the absorption rate showed negative balance.

Chemical analysis, statistical analysis and geochemical study were carried out to investigate the influence of the geology on the chemical characferistics of the mineral water in Taegu area. A simple comparision between the chemical components of the mineral water and their bedrocks indicates that the bedrock types in the catchmerit area control the chemical characteristics of the surface water. However more objective evidences for the mineral water-bedrock relationship come from the statistical analyses(cluster analysis and factor analysis). The results of the statistical analyses suggest that the bedrock type factor explains the data variation seven times as much as pollution does, which evidently indicates that the bedrock in the study area mainly control the mineral water chemistries. The results of comparision of the statistical analyses results with the mineral weathering reactions and mineral stability diagrams can be summarized as follows: 1. Plagioclase weathering to kaolinite provides SiO$_2$ , Ca$^{2+}$ and Na$^+$, and muscovite weathering to kaolinite provides K$^+$, and amphibole and mica minerals weathering to kaolinite provides F to the mineral water. Most of Ca$^{2+}$ and Mg$^{2+}$ in the mineral water are the products of carbonate mineral dissolution. SO$_4^{2-}$ may be the byproduct of sulfide oxidation. 2. The weatering of silicate mineral produces Ca-rich smectite and kaolinite, but Ca-rich smectite is unstable and will be transformed to more stable kaolinite because of the continuous dilution of the mineral water by precipitation. By Hashimoto's Mineral Balance Index, S-10 and S-12 mineral spring water were evaluated tasty and healthy water, S-9 and S-11 mineral spring water were evaluated tasty water and S-7, S-8 and S-13 mineral spring water were evaluated healthy water.

Purpose: The purpose of this study was to examine the effects of Tai Chi exercise on muscle strength, balance, flexibility and bone mineral density among community dwelling elderly women. Methods: A quasi-experimental pretest-posttest design with a nonequivalent comparison group was utilized, Elderly women were recruited from the community settings and assigned to either the treatment group (n=30) or the comparison group (n=34). Both groups completed the pretest and the posttest measures at six months with an 29.7% of dropouts. Tai Chi exercise was performed for 60 minutes, three times a week for 24 weeks. The study participants were referred to the sports clinic of the university hospital where an exercise therapist and a technician measured muscle strength, balance, flexibility, and bone mineral density without the knowledge of the group assignment. Data were collected from June 14, 2010 to May 27, 2011. Results: At the completion of 6 month Tai Chi exercise, the experimental group showed a significant difference in knee flexor strength (t=3.26 p=.002), flexibility (t=-2.93, p=.005), and bone mineral density in femur (t=2.20, p=.032), compared to the control group. Conclusion: Tai Chi exercise could be performed safely to community dwelling elderly women and effective for preventing declining in physical function in this population. Whether or not this health benefits would lead fall prevention will require further study.

Background: The aim of the present study was to determine the effects of feeding trace mineralsfortified mixed microbial culture (TMC) on ruminal fermentation, nutrient digestibility, blood electrolyte status, nitrogen balance, and trace mineral balance in sheep. Methods: Mixed microbes [0.6 % (v/w) of Enterobacter sp., Bacillus sp., Lactobacillus sp., and Saccharomyces sp.] were cultured with 99 % feedstuffs and 0.4 % trace minerals including zinc and copper for ensiling. Six sheep (a mean body weight of $46.5{\pm}1.2kg$) were fed two diets: a control diet (concentrate mix and rye straw) and an experimental diet (a control diet + 3.1 % TMC). Results: TMC feeding did not induce negative effects on ruminal fermentation, nutrient digestibility, blood electrolytes, and nitrogen balance in sheep. Feeding with TMC increased the intake of trace minerals (p < 0.05) and did not affect absorption of trace minerals in the whole digestive tract. Feeding with TMC increased fecal excretion and absorbable intake, and retention of zinc and copper (p < 0.05) by 71 % and 77 %, respectively. Conclusion: Feeding with TMC resulted in higher zinc and copper bioavailability and retention without any adverse effects on sheep performance.

Groundwater chemistry in Namwon area, Korea, was investigated to understand the contribution of geochemical processes on groundwater chemistry. For this study, a total of 279 groundwater samples were collected from 93 wells distributed over the study area. Higher concentrations of major ions are generally encountered in the shallow alluvial wells, suggesting that these chemicals are originated from the surface contamination sources. Mass balance analysis based on reaction stoichiometry reveals that the water chemistry is regulated by three major chemical processes: weathering of silicate/ carbonate minerals, input of C1/SO$_4$ salts, and nitrate generating processes. The results show that mineral weathering is the most dominating factor regulating the groundwater chemistry. However, the groundwaters with the higher salt concentration indicate the larger mineral weathering effect, suggesting that some part of the mineral weathering effect is also associated with the anthropogenic activities such as limes applied to the cultivated lands, carbonates (CaCO$_3$) in the cement materials.

Purpose: The purpose of this study was to examine the effects of Tai Chi exercise on flexibility, balance, walking ability, muscle strength, bone mineral density, and fracture risk in institutionalized elders. Method: A quasi-experimental pretest-posttest design with a nonequivalent comparison group was utilized, and 53 older adults living in one institution were recruited and assigned to one of two groups, experimental group (18) or comparison (20). Both groups completed posttest measures at 6 months. There was a 31% rate of dropouts. Tai Chi exercise was provided twice a week for 24 weeks. Outcome measurements were conducted by a physiotherapist at a university hospital health promotion center who did not know the group assignment. Results: At 6 months, the experimental group had significantly greater grip strength(t=2.12, p=.04), back muscle strength (t=2.42, p=.02), balance (t=5.31, p<001), and flexibility (t=3.57, p<.001). They also showed significantly greater bone mineral density of lumbar spine and femur, and reduced fracture risk. Conclusion: Tai Chi exercise was safely and effectively used with institutionalized elders for 6 months and significantly improved physical fitness, bone mineral density along with a reduction in fracture risk. Whether Tai Chi exercise would lead to prevention of fall episodes and fall related fractures in this population will require further study.
