The overall purpose of this study was to investigate the effects of level of isoflavones supplementation on bone metabolism in growing female rats. The effects of level of isoflavones supplementation on bone mineral density (BMD) and bone mineral content (BMC) were inspected in this study. Forty-five rats divided into three groups: Casein, $^1/{_2}IF$, IF. The serum and urine concentrations of calcium and phosphorus were determined. BMD and BMC were estimated by using PIXImus (GE Lunar Co, Wisconsin.) in spine and femur on 3, 6, 9 weeks after feeding. This study of results were as follows: The isoflavones supplementation level did not affect weight gain, mean food intake and food efficiency ratio. The serum concentration of calcium, phosphorus were not significantly different by different level of isoflavones supplementation. The urinary calcium and phosphorus excretion were not significantly different, too. Spine and femur BMD, BMC were not significantly increased by different level of isoflavones supplementation on 3 and 6 weeks after feeding. Spine BMD and spine BMC per weight, femur BMC per weight were significantly increased in the groups $^1/{_2}IF$ and IF at the ninth week after feeding, but there was no significant difference by different level of isoflavones supplementation. Spine BMD per weight and femur BMD per weight were significantly higher in the group of IF than in the group of Casein and $^1/{_2}IF$ at the ninth week after feeding. These results suggest that the group of IF with rich isoflavones supplementation was effective to the increase of BMD spine and femur in growing female rats, respectively.

The primary objective of this study was to learn the effect of various sugar particle size and level on cookie spread, The effect of sugar particle size and level on sugarsnap cookie spread was studied. Three different particle sized sugars; powered sugar, granulated sugar and sanding sugar, were used for the cookie test baking with five different sugar levels; 30, 45, 60, 75 and 90% based on the weight of flour. In mixing process, 5 minutes of creaming time was used for cream making and then the specific gravity of cream was measured on the basis of each different sugar particle size and level. In the result, the specific gravity of cream was influenced by sugar particle size and sugar level. However, the specific gravity of cream had no influence on cookie dough specific gravity. Cookie spread was influenced by sugar particle size and sugar level. Greater cookie spread was obtained by decreasing sugar particle size and increasing sugar level resulted in increased spread. Therefore, selection of suitable sugar particle size and its use level can be factors in controlling spread and imparting desired packaging characteristics.

The research was designed to study the effect of different fat sources and levels on Body lipid metabolizm and immune responses in Sprague-Dawely strain male rats. These effect of different fat sources compared with sesame Oil, Perilla oil and Beet tallow. Fat sources were divided into 3 groups respectively 7%, 15%, 30% fat level on diet weight basis. The experimental period was 54days. 1) The body weight gain was significantly low in NF group. In Sesame oil group and perilla oil group, low fat level groups were higher than medium, high fat level groups. But in Beef tallow group, high fat level groups were higher than low and Medium groups. 2) The weight of liver, kidney and epididymal fat ped tend to increse with increasing body weight. 3) The contents of triglyceride and total lipid in serum were significantly different with dietary fat sources and Perilla oil group was the lowest. 4) The contents of triglyceride and total lipid in liver were significantly different with dietary fat levels and high fat level group was higher than low fat level group. 5) Perilla oil group, compared with Beef tallow group, showed the higher excretion of cholesterol through feces and the higher deposit of cholesterol in liver. Therefore serum cholesterol level of Perilla oil group was lower than that of Beef tallow group. But eventhough Sesame oil is vegetable oil, Sesame oil did not showed an effect like Perllia oil on serum cholesterol level. 6) Weight of thymus decreased with fat levels particularly in vegetale oil. And it had on effect on mitogen response, mitogen response decreased with fat level in vegetable oil. But in Beef tallow, there was no difference in fat level.

An irrigation scheduling model, IRIS developed to evaluate irrigation demand and irrigation time for upland crops. For IRlS modeling the soil moisture simulation model, SWATRER was adopted and modified. The developed model, IRIS operated under 5 different soil moisture level that is 20%, 40%, 60%, 80% of available soil moisture and optimum soil moisture level, OSML, which is different about the growing stage and no rainfall condition during growing period. As a result for IRIS simulation, irrigation demand for 5 different soil moisture level was 332.3, 409.8, 569.3, 732.2, 539.3mm, irrigation number was 5, 8, 18, 54, 16 times and irrigation interval during peak time of consumptive use was 20, 13, 6, 2, 6 days respectively. It is appeared that the higher soil moisture level the more irrigation demand and irrigation number and the higher soil moisture level the less irrigation interval.

This paper examines how L2 speech production varies according to learner's L2 proficiency level. L2 speech production variations are analyzed by quantitative measures at word and phone levels using Korean learners' English corpus. Word-level variations are analyzed using correctness to explain how speech realizations are different from the canonical forms, while accuracy is used for analysis at phone level to reflect phone insertions and deletions together with substitutions. The results show that speech production of learners with different L2 proficiency levels are considerably different in terms of performance and individual realizations at word and phone levels. These results confirm that speech production of non-native speakers varies according to their L2 proficiency levels, even though they share the same L1 background. Furthermore, they will contribute to improve non-native speech recognition performance of ASR-based English language educational system for Korean learners of English.

The purpose of this study is to identify the most important factor(s) that contribute(s) to the overall oral proficiency and to examine whether the factor(s) play(s) a different role depending on the proficiency level of learners. Learners were divided into novice group and advanced group and were asked to produce an oral recording of a story based on a comic strip. The recordings were transcribed and graded by three raters. According to the results, the raters attained high inter-rater reliability when assessing advanced learners. However, the reliability level became considerably lower in the assessment of novice learners. The best predictor of oral proficiency among novice learners was sociolinguistic competence and fluency, while grammatical competence and fluency were the strongest predictors for advanced learners. The results suggest the need for a separate assessment tool for different proficiency levels and the need for a different focus in the classroom depending on the learners' proficiency level.

Osteoporosis is a age-related metabolic disorder. Currently there is no cure, but there are measures that can prevent or deter the development of osteoporosis. Futhermore lifestyle among risk factors of osteoporosis may be modifiable. Osteoporotic preventive health promotion behavior may be more effective at early adult when they make formation of peak bone mass. The purpose of this study is to identify the demographic variables, life-style and level of concern about osteohealth-related factors according to the health promotion behavior among university female students. The result are following: 1. The highest level of concern about osteoporosis-related factor is sufficient sleeping. 2. The highest level of dietary about osteoporosis-related factors are vegetable and fruit. 3. Level of concern about osteoporosis-related factors according to demographic variables are not significantly different, but dietary were significantly different in age, height and income. 4. Level of concern about osteoporosis-related factors according to lifestyle are significantly different in weekly hour of exercise and weight control, and dietary are significantly different in milk intake at elementary school and present. 5. Level of concern about osteoporosis-related factors have correlated positively with dietary. University and College female students who participated in this study have concerned middle at calcium intake and exercise, but two variables are significantly different in lifestyle and dietary. Because of two variables are modifiable, it should be regarded importantly in nursing domain. We suppose that preventive education of osteoporosis is necessary to reach peak bone mass and to maintain bone mass consistently among the University and College female students.
