It was hypothesized that variations within the range of usual calcium(Ca) and sodium(Na) intakes of Korean influence bone mineral density(BMD) in healthy premenopausal women The relationship of nutrient intake urinary excretion physical activity and circulating IGF-1 level with spine({{{{ { L}_{2 } }}}}-{{{{ { L}_{4 } }}}}) and femur BMD was determined in 47 normal premenpausal women. There was a positive relationship between BMD of the lumbar spine and body weight. The BMD of femoral neck was positively correlated with Ca and protein intakes from animal source and circulating IGF-1 level. There was a negative relationship between femur BMD and both Na intake and urinary excretion. The complex interrelations between femur BMD regression analysis, From this analysis. Ca intake from animal origin was the only significnat Premenopausal women of femur BMD. In the basis of femur BMD three groups were divided Premenopausal women of femur BMD$\leq$0.84g/cm2 showed depressed Ca intake of animal origin in later and early life and enhanced urinary Na excretion compared to women of femur study suggests that dietary Ca is a major constituent affecting femur BMD because of a decrease in net Ca absorption and an increase in urinary Ca loss.

Objectives : We performed this study to analyze correlation among hair tissue minaral ratio, autonomic function and obesity. Methods : Subjects were gathered from January 2005 to March 2007. This study was carried out on 263 subjects who had visited Garosero oriental clinic and had no previous cardiovascular disease and thyroid disease. Heart rate variability (HRV) parameters, tissue mineral ratio and obesity degree were statistically compared with correlation and T-test analysis. Results : The results of this study are summarized as follows : 1. Normal group were predominant over obesity group in HRV parameters(SDNN, RMSSD, VLF, LF, HF). 2. Ca/P, Ca/K, Na/K and Fe/Cu, Na/Mg ratio in hair tissue mineral ratio have correlation with BMR, BMI and waist circumference. 3. Ca/P ratio has correlation with LF norm in HRV, and Na/K with HF, Na/Mg with LF, equally. Conclusions : Taken together these results may suggest that there are significant relationships between hair tissue mineral analysis and HRV.

This experiment was canied out to study the effect of cutting frequencies (3, 4 and 5 cuts per year) and mineral nitrogen fertilization on dry matter yields, in order to estimate optimum level of fertilizing mineral nitrogen in orchardgrass(Dacry1is glomerafa L.). The results are as follows: 1. Dry matter yields were the highest in the 1st cut at 3 cutting frequency and in the 2nd cut at 4 and 5 cutting frequencies, and they shared 49.7, 37.0 and 37.0% of annual dry matter yield respectively. 2. When only phosphorus and potassium were applied, annual dry matter yields were between 9.4 and 11.5 tons per ha and the highest yield was observed at 3 cutting frequency. 3. Dry matter yield in relation to fertilization of mineral nitrogen was highly increased when more nitrogen was applied as 360 kg per ha compared to 240 kg per ha at 3 cutting frequency. At 4 and 5 cutting frequencies, increases in dry matter yield, to large extent, were showed at 120 and 150 kg of nitrogen per ha(30 kg Nlcutlha) compared to no application of nitrogen. The efficiencies of mineral nitrogen fertilization (kg DM/kg N) were 28.0, 22.7 and 20.6 kg dry matter yields per nitrogen(kg) respectively). 4. At 4 and 5 cutting frequencies, dry matter yields were reduced when 360 kg and 300 kg of mineral nitrogen per ha(90 kg and 60 kg Nlcutlha) were applied respectively. 5. Particularly at 4 and 5 cutting frequencies of this study, maximum marginal yields reached at 129.9 kg and 148.0 kg of fertilizing mineral nitrogen per ha, and economical borden of mineral nitrogen fertilization were between 222.4 and 250.0 kg and between 244.8 and 276.8 kg respectively. At the same cutting frequencies, the highest dry matter yields were obtained at 365.4 and 433.8 kg of fertilizing mineral nitrogen respectively.

The experiment was canied out to investigate the effects of cutting frequencies (3, 4 and 5 cuts per year) in relation to fertilization of mineral nitrogen on crude protein yield and the contents of crude protein and acid detergent fibre in orchardgms(Dacty1is glomerata L.). Tne results are as follows : 1. The content of crude protein increased according to the increase in cutting frequency and showed the highest in the 1st cut in all treatments. At 4 and 5 cutting frequencies per year, the content of crude protein increased in a large extent according to the increased fertilization of mineral nitrogen. However at 3 cutting frequency, the content of cmde protein appeared higher for no application of mineral nitrogen than for the treatments with fertilization. 2. 'Ihe content of acid detergent fibre(ADF) was considerably reduced at 4 and 5 cutting frequencies and in all treatments, the lowest were recorded in the 1st cut or in the last cut. At 3, 4 and 5 cutting frequencies, the highest ADF were shown in the 2nd cut, 3rd cut and 3rd cut respectively. However, the general trend was that the content of ADF was greatly reduced according to increased level of mineral nitrogen fertilization. 3. The yeild of cmde protein was the highest at 5 cutting frequency(l.2 ton DMIha) and it indicated that the yield of cmde protein increased in accordance to the increase in fertilization of mineral nitrogen and cutting frequency. 4. In all treatments, positive correlation(p<0.001) between the yeilds of crude protein and annual dry matter yield appeared. Negative correIation(p

In this study, we determined the ingredient analysis of harvested garlic bulb and soil analysis of four garlic-cultivated regions in Jeju, being one of the major areas of Namdo garlic production. Soil pH and electric conductivity were 7.02 and 1.03 dS/m, respectively. Soil organic matter was 4.31%. The mineral elements (potassium, calcium, magnesium, sodium, iron, manganese, copper and zinc) of Namdo garlic cultivated soil were analyzed by ICP, and calcium was the most highly contained mineral with $14.67cmol_+/kg$ and in the decreasing order of magnesium ($2.25cmol_+/kg$), potassium ($1.51cmol_+/kg$). Soluble solid and total acidity were 7.60 oBrix and 0.49%, respectively. The mineral contents of garlic bulb were in order of potassium (12,728 ppm) > sulfur (7,778 ppm) > phosphorus (4,916 ppm) > magnesium (691 ppm) > calcium (359 ppm). The content of total phenolic, total flavonoid and reducing sugar were 71.14 mg GAE/100 g, 17.64 mg QE/100 g and 26.53 mg GE/g, respectively. Alliin and allicin were 8.78 mg/g and 2.10 mg/g, respectively. The Pearson's correlation coefficients between mineral contents of soil and garlic bulb are analyzed. Macronutrients of soil is correlated with macronutrients of garlic (positive) and micronutrients of garlic (negative) contents.
