The purpose of this study was to investigate the correlation of BMI and physical fitness in high school girls. The subjects were high school girls(n=295). The measurement items are physical fitness, physique, physique index(BMI : Body Mass Index). The conclusion of this study was as follows; 1. The record of 100M sprint, standing long jump, and sit ups showed a slack downward curve(low record) as BMI rises. 2. The record of softball showed a slack upward curve(high record) as BMI rises. 3. The record of 800M run, sit-ups and softball throw, from the top to the bottom. 4. The order of correlation between BMI and physical fitness was, flexed-arm hang, 100M sprint, standing long jump, 800M run, sit-ups and softball throw, from the top to the bottom. Therefore, we concluded that correlation BMI and physical fitness showed not so high.

The focus of this study was the influence of organic acids such as acetic, citric and malic acid on the dissolution of calcium (Ca), magnesium (Mg), and phosphorus (P) on chicken thigh bone. As the concentration (0, 0.5, 1, 2, 4%) of acetic, citric, and malic acid increased, the resultant contents of calcium, magnesium, and phosphorus were higher than that of the control. When the boiling time (2, 4, 6, 8, 12 hours) was increased, dissolved amounts of several minerals from the chicken thigh bone increased- Calcium dissolved the most when chicken stock was boiled for 12 hours with 4% of malic acid added. In addition to minerals, amino acids and proteins were further extracted by adding organic acids. The soup stock, which contains minerals such as calcium, can be obtained by boiling the chicken thigh bone for 12 hours with an organic acid.

The purpose of this study was to identify the change of the dietary pattern, food craving in accordance with menstrual cycle among women with the premenstrual dysphoric disorder(PMDD) and women with no premenstrual symptoms(Non-PMS). The 24 subjects were divided by two groups, PMDD group and Non-PMS group. And the change of dietary pattern and food craving were measured for 4 weeks according to the menstrual cycle. The frequency of meal, the amount of meal and the change of palatability of meat intake, fatty food, carbonate drinks, fruit, confectionery and caffeine containing beverage were more significantly increased in luteal and menstrual phase than follicular phase without regard to PMDD group and Non-PMS group, but there were no statistically difference between groups. The change of palatability of vegetable & alcohol were no difference among the phase without regard to PMDD group and Non-PMS group, and there were no statistically difference between groups. Above the findings showed that the change of women's dietary pattern has connection with the change of menstrual cycle. It is considered that unconsidered variables in this study could be applied for the therapy of premenstrual symptom or management method in connection with variable related to menstrual cycle the systematic study is requested.

The method of creep feed grinding is an effective technology process. It is used to improve the productivity & efficiency in form grinding. However there are some inherent difficulties throughout the grinding process. The progress of abrasive wear around the cutting edge is remarkable. The grinding force become intense and burn marks occur frequently. To grind a work piece of large length is clearly a tremendously difficult task. Also, domestically, creep feed grinding is a scarce development. We crucially depend on the imports of goods from abroad. Therefore, the purpose of this research is that developing the localization creep feed grinding with continuous dressing device and we must research more into this complex technology to discover the most efficient dressing conditions and dresser to wheel speed ratio(qd).

This study was conducted to investigate the effects of corn peptide(CP) on lipid metabolism. Sprague-Dawley(S.D) male rats were assigned to three dietary groups {control diet(CD), high fat diet(HFD) & high fat com peptide diet(FCD)}l and fed 4 weeks to examine the effects of CP. There were no significantly different in cholesterol concentrations in the liver among the groups. However, triglyceride(TG) concentrations of the FCD & CD significantly lower than the HFD. Fecal excretion of neutral steroids & bile acids of the FCD significantly higher than the CD & HFD. Serum total cholesterol, TG & LDL-cholesterol concentrations of the FCD & CD significantly lower than the HFD. These results suggest the improvement of lipid composition in serum by CP might be inhibit of lipid absorption in intestine & increment of neutral steroids & bile acids excretion in feces.
