종류가 다른 채소 3종을 임의로 선정하여 마우스의 Na, K, Ca, Fe, Cu, Zn, Mg 밸런스에 어떠한 영향을 미치며, 또한 채소의 종류나 양, 사육기간이 영향을 미칠 수 있는 요인인지 조사하였다. 실험동물은 8주된 SPF계 마우스 130마리를 사용했으며 평균 체중은 $29{\sim}38g$이었다. 마우스 10마리를 대조군으로, 나머지 120마리를 3군으로 나누어 이를 다시 두군으로 나누어 한마리씩 분리 사육시켰다. 대조군은 물(2차 증류수)과 식이를 제한없이 주고 다른군은 물 대신 임의로 선정한 채소 3종(당근, 껍질콩, 호박)으로 대체하고 각군 20마리 중 10마리는 1주(단기간) 10마리는 2주(장기간) 사육시켜 실험 완료일 까지의 실험식이 섭취량이 대조군과 유의적인 차가 없는 마우스만을 실험대상으로 하였다. 또한 이들 채소의 양에 따라서 당근대량군(12마리), 당근소량군(10마리), 껍질콩대량군(11마리), 껍질콩소량군(9마리), 호박대량군(10마리), 호박소량군(14마리)으로 분류하였다. 체중증가는 대조군에 비하여 껍질콩대량군이 높게 나타났으며, 식이 효율은 대조군에 대한 차이가 없었다. 분변과 요량은 채소 급여에 의하여 증가하였다. 체중증가와 식이효율, 분변과 요량에는 채소의 종류나 양, 사육기간등이 작용인자로는 확인되지 않았다. 무기질 섭취량은 대조군에 비하여 Na, Ca, Fe, Cu가 호박대량군에서 가장 낮게 나타났고, K는 당근대량군이 가장 높게 나타났으며 Zn, Mg는 껍질콩대량군에서 가장 높게 나타났다. Na, K, Ca, Fe, Cu, Zn, Mg의 흡수율과 밸런스는 대조군이 플러스의 균형을 나타내는데 반하여 채소 급여군은 모두 마이너스의 균형을 나타내었다. 채소의 종류, 양, 사육기간이 Na, K, Ca, Cu, Zn의 섭취량에, Cu, Zn의 흡수율에, K, Cu, Zn 평형에 각각 영향을 미치는 요인인 것으로 확인되었다. K, Zn, Mg는 대조군에 비하여 실험군의 섭취량이 증대 했음에도 불구하고 흡수율은 마이너스이였다.

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.

Purpose: This study examined the effects of an exercise program involving the Proprioceptive Neuromuscular Facilitation (PNF) lower-extremity patterns on the Bone Mineral Density (BMD), balance and lower muscular strength in patients with osteoporosis. Methods: The participants were allocated randomly to 2 groups: experimental group and control group. To evaluate the effects of exercise, the subjects were evaluated using the BMD and Time Up & Go Test and One Leg Stance Test for balance, and the Sit To Stand for lower muscular strength. Results: After the 8 week study, the experimental group showed a significant difference in all items compared to the control groups. Conclusion: These results suggest that a PNF exercise program is effective in patients with osteoporosis. Furthermore, an exercise program involving these patterns can be used in a follow-up program for patients with osteoporosis. Overall, more study will be needed to develop and apply more efficient exercise programs for such patients.

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.
