501 preschool children from 4 to 6 years were examined for their salivary reductase activity and caries experience by Resazurin Disc Test and dental examination respectively. We asked the parents about their children's oral hygiene habits, between-meal eating habits, and physical exercise habits by the questionnaire. Toothbrushing frequency had negative relation to salivary reductase activity and caries experience. Caries experience was low when parents did toothbrushing for children, when teeth were brushed at bedtime, and when fluoride toothpastes were used. Salivary reductase activity and caries experience were high in bread & cookies group, chocolates & candies group, milk & soft drink group, and fruits & vegetables group in order. Caries experience was high in case of irregular between-meal eating. Sweet food eating frequency had positive relation to caries experience. Caries activity was low in case of eating homemade non-sweet between-meals. Salivary reductase activity and caries experience were low when gum-chewing frequency was high. Salivary reductase activity and caries experience were high when the amount of physical exercise was low.
The elevation of plasma total homocysteine(tHcy) is now established as a risk factro for cardiovascular disease. It is also well known that plasma levels of folate and vitamin $B_{12}$ influences homocysteine metabolism as cofactors. Recently, the effects of health-related lifestyle factors, such as smoking, alcohol drinking coffee consumption, regular exercise, and etc, on plasma tHcy have been determined. The Hordalane Homocysteine Study revealed that smoking and coffee consumption are major deter minants of plasma tHcy as well as folate levels; however, the influence of alcohol intake is still controversial. In Koreans, the effects of lifestyle factors of plasma tHcy have not yet been determined. Thus, we investigated the relationships of various lifestyle determinants with plasma tHcy, folate, and vitamin $B_{12}$ levels and the erythrocyte folate concentrations in Korean adults (99 males and 96 fermales). Plasma tHcy levels were significantly hight in male subjects. On the contrary, plasma levels of folate and vitamin $B_{12}$ and erythrocyte folate concentration of the females were significantly higher than those of the males. Among the five lifestyle factors determined in the study, regular exercise significantly affects plasma tHcy levels only in the females, Contrary to the expectation, there were on significant differences in plasma tHcy levels between alcohol drinkers and non-alcohol drinkers as well as smokers and non-smokers. And also, plasma tHcy leverls were not different between coffee consumers and non-coffee consumer and between green tea consumers and non-green tea consumers. Although alcohol intake did not influence plasma tHcy levels, the duration, frequency, and amount of alcohol drinking showed significant negative relationships with plasma folate levers. These results indicate the regular exercise and alcohol intake might influence plasma levels of tHcy and folate in Koreans, although the results were not reveled in both sexes.

In this research high-fat-diet, which amounts to 40% out of the total calories, is prepared and taken to SD-lined rats for four weeks, and the exercise is taken using treadmill so that two groups are formed; one is for exercise group (E, EG) and the other for non-exercise group (CO,G). In addition the diet-intake-amount and body weight are measured for momparing a green tea extract intake group (EG,G) with a non-intake group (CO,E) and then serum lipid components can be analyzed after four weeks. Considering the total diet amounts for four weeks, Co group has the largest while the EG group does the smallest for the diet-intake-amounts; there is, however, no significant difference among all groups. Both body weight gain and the feed efficiency ratio of the CO group are larger than those of the EG and G group with significant differences (p<0.05). Taking into account the serum lipid components analysis, all of serum total cholesterol, LDL-cholesterol, and triglyceride of EG group have smaller values than those of non-exercise groups (CO,G) with significant differences (p<0.05) respectively, while HDL/LDL-cholesterol of EG group does a larger value than that of non-exercise groups with significant difference (p<0.05); these, hence, show efficient results. For the HDL-cholesterol level, there are no significant differences among each group and the ratio TC/HDL-cholesterol of EG group is smaller than that of Co group with a significant difference (p<0.05). Therefore, we can draw conclusions that exercise and green tea extract intake group (EG) has relatively better results than non-exercise groups (CO, G) through serum lipid components results and furthermore the effects of the green tea extracts intake is considered to play a supplementary role for the improvement of the serum lipid components.
Recently high interest in health and fitness has led to vibrant researches for the active fitness system to learn and enjoy the exercise program for oneself. In this paper, we design and implement the active spinning training system which enables user to have self-learning and experience of customized spinning training program by the biometric and movement information acquired from user's physiological signals. The proposed system provides the appropriate difficulty of spinning program which reflects the concordance rate of spinning dance gestures and the amount of exercising by analyzing the physical status of participant from his brain and pulse waves and recognizing the skeletal movement in real time. For the higher exercise effect, the system offers a virtual personal trainer to show the correct poses and controls the level of difficulty depending on the concordance rate of participant's motions. The experiment with various participants through the proposed system shows that it is able to help users in getting the available exercise effect in comparatively short time.
Physiological analysis of the physical exercise was made on 9 subjects performing mountain climbing. The course between two points (256 and 516 meters altitude) was 1,300 meters in distance and difference of vertical height was 260 meters making the mean grade of 20%. In the field, the heart rates during uphill or downhill walk were recorded by EKG radio-telemetry. In the laboratory, oxygen consumption was obtained by the recorded heart rates, using individual heart rate vs oxygen consumption diagram obtained by treadmill test. the following results were obtained. 1. Uphill walk time was 36.5 minutes, and during this period the mean heart rate was 149.0 heats/min and peak heart rate was 169.2 beats/min. The total heart beats during the uphill walk was 5.433 beats. 2. The ratio of individual mean heart rate during the uphill walk to the maximal heart rate distributed between 66.6% and 98.3%, and the mean of the total group was 83.1%. The ratio of peak heart rate of uphill walk to the maximal heart rate was 94.5% in the group. Thus uphill walk of a 20% grade mountain course was an exhaustive exercise. 3. Oxygen consumption during uphill walk was 2.22 l/min (ranged between 1.79 and 2.70 l/min) and the ratio of this to the resting oxygen consumption was 8.31. The peak value of oxygen consumption during uphill walk was 2.73 l/min and the ratio of this to the resting oxygen consumption was 10.39. 4. Energy expenditure during uphill walk showed a mean of 11.1 kcal/min and the peak expenditure rate was 13.6 kcal/min. The total energy expenditure during 36.5 minutes of uphill walk was 396 kcal. 5. In downhill walk, the time was 31.7 minutes, mean heart rate was 118.4 (ranged between 100.1 and 142.7) beats/min, and the peak heart rate was only 129.4 beats/min. The ratio of mean heart rate to the maximal heart rate was 66.3%. Total heart beats during downhill walk was 3,710 beats. The ratio of downhill oxygen consumption to the resting consumption was 5.70. The rate of energy expenditure was 7.5 kcal/min, and the total onery expenditure during the 31.7 minutes of downhill walk was 228 kcal. 6. The effect of training was manifest in the uphill walk and not in the downhill walk. After training in mountain course walk, i) the uphill time was shortened, ii) mean heart rate increased, iii) time vs heart rate curve became smooth and showed less frequent zig-zag, i.e., the depth of trough on the curve decreased and the magnitude was less than 10 beats. In non-trained subject the depth of trough on the curve was greater than 50 beats and appeared more frequently. 7. Mountain climbing is a good health promotion exercise. For the promotion of health the reasonable amount of uphill mountain walk exercise in a 20% grade course is a walk for 40 or 50 minutes duration once a week.
The purpose of this study was to identify the effect of cerebral ischemia on affected(Lt) and unaffected(Rt) side of soleus, plantaris and gastrocnemius muscle mass and determine the effect of exercise on affected and unaffected side on soleus, plantaris and gastrocnemius muscle mass during acute stage of stroke. Sixteen male Sprague-Dawley rate with 200-270g body weight were randomly divided into three groups: control, stroke, and exercise after stroke(St+Ex) group. The control group received sham operation and the stroke group and St+Ex group received transient right MCA(middle cerebral artery) occlusion operation. The St+Ex groups ran on a treadmill for 20min/day at 10m/min and $10^{\circ}$ grade for 6days. During the experimental period body weight and diet intake was measured every morning. On the 7th day after operation, muscles were dissected from both affected and unaffected side of hindlimb. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30 minutes. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Significance was accepted at the level of p<0.05. The results were summarized follows : 1) There were no significant difference of the body weight on the first day of experiment among 3 groups. Whereas on the 7th day, the body weight of both stroke group and St+Ex group were significantly smaller than that of control group. Body weight of St+Ex group on the 7th day tended to be larger than that of stroke group. 2) Total diet intake of both stroke group and St+Ex group were also significantly smaller than that of control group. While total amount of diet intake in St+Ex group tended to be larger than that of stroke group. 3) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of control group and the weight of soleus and plantaris muscle of affected side in stroke group tended to decrease compared to that of control group. 4) The weight of plantaris muscle of unaffected side in stroke group significantly decreased compared to that of control group and the weight of soleus and gastrocnemius muscle of unaffected side in stroke group tended to decrease compared to those of control group. 5) The weight of gastrocnemius muscle of affected side in stroke group significantly decreased compared to that of unaffected side and there was no significant difference of the weight of soleus and plantaris muscle in stroke group between affected side and unaffected side. 6) The weight of soleus, plantaris and gastrocnemius muscle of both affected side and unaffected side in St+Ex group had a tendency of increase compared to those of stroke group. The relative weight of soleus and gastrocnemius muscle of affected side and soleus muscle of unaffected side in St+Ex group had a tendency to increase compared to those of stroke group. Based on these results, exercise during acute stage of stroke might attenuate muscle atrophy of both affected and unaffected side of hindlimb muscles.
Software for analyzing documents on the net to detect specific categories of occurrences is in great demand. In the current world where detecting terrorist threats is critical there is a great need for such systems. One of the critical application areas of such software is the automatic detection of a national infrastructure emergency. In this research an agent-based generic architecture for emergency warning systems is proposed and implemented. This system, called the National Infrastructure Emergency Warning System (NIEWS), is designed to analyze given documents, to detect threats, and to report possible threats with the necessary information to the appropriate users autonomously. In addition, a systematic analysis framework to detect emergencies on the subject of defensive information warfare is designated and implemented through a knowledge base. The developed system along with the knowledge base is implemented and successfully deployed to Strategic Crisis Exercise (SCE) at the United State Army War College (USAWC), saving a good amount of money by replacing human SMEs (subject matter experts) in the SCE.
This study was designed to investigate the effects of aerobic dancing and/or Ca supplemen-tation for six months on Ca metabolism in postmenopausal women. The subjects were healthy 29 women aged from 60 to 70 years old. They were divided into four groups ; placebo and Ca supplementation group with and without exercise. The amount of Ca supplemented was 500mg a day. The frequency of doing exercise was three times a week and it took 40 minutes to complete once all the course of aerobic dancing programmed for old women. The results were summarized as follows : 1) Bone density of the second lumbar spine and ward's triangle measured after experiment decreased significantly in control group as compared with pre-experimental level(P<0.05). On the contrary it showed a tendency to increase or maintained the pre-experimental level after experiment in other groups. 2) Urinary Ca/creatinine and P/creatinine ratios did not show any significant differences among groups before and after experiment. But urinary Ca/creatinine ration decreased signifi-cantly in Ca group after experiment(P<0.05) 3) Serum Ca and P levels did not show any significant differences among groups before and after experiment. But serum Ca level in creased significantly in Ca group after experiment(P<0.05) 3) Serum Ca and P levels did not show any significant differences among groups before and after experiment. But serum Ca level increased significantly in Ca group after experiment (P<0.05). 4) Serum PTH level also did not show any significant differences among groups before and after experiment. But serum calcitonin level decreased significantly in Ca group after experiment(P<0.05). The above results showed that it will be difficult to prevent degenerative bone loss without regular exercise and/or Ca supplementation in postmenopausal women having Korean usual diets.
