Purpose: In this study, the following experiment was conducted to see how to apply the sprinter pattern in proprioceptive neuromuscular facilitation (PNF) and functional weight bearing exercise affected balance capabilities and weight bearing among chronic stroke patients. Methods: The subjects included 27 subjects who had been diagnosed with hemiplegia due to stroke. A total of 12 sessions was held, 3 sessions a week over 4 weeks, were provided to the groups. The control group received general rehabilitation program, and the experimental group performed sprinter pattern in PNF or functional weight bearing exercise. The weight bearing capability and static balance capability test was implemented by using Good-Balance System and Frailty and Injuries Cooperative Studies of Intervention Techniques, while the dynamic balance capability test was carried out by using Four Square Step Test and Timed "Up and Go". Results: The paretic/nonparetic side weight bearing by application of each exercise showed that there were no significant differences in variation among each groups on before exercise, after exercise, 2 weeks after exercise. Static balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Dynamic balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Conclusion: To put the results together, the application of sprinter pattern and functional weight bearing exercise was effective in improving static and dynamic balance capabilities. Therefore, these exercises are helpful to improve balance in patients with stroke.

This study was performed to provide sources of nutrition education for female adolescents by identifying eating disorder patterns and their relationships with self-body image, weight control, and eating behavior. A total of 329 female middle school students were recruited and completed a general characteristics survey, the Eating Attitudes Test(EAT-26), a perception of self-body image survey, a concern for weight control survey, an eating behavior survey, and the Mini Dietary Assessment Index(MDA). Eating disorder patterns were identified to be obesity stress and weight control(OW), risk of binge eating(RB), and dietary restraint(DR) by factor analysis. OW pattern was related with stout body shape, body dissatisfaction, experience of weight control, skipping of dinner, and low MDA score. RB pattern was associated with lean body shape, body satisfaction, indiscreet snack behavior, and the eating time of snacks. The DR pattern was associated with normal body shape, regular meal times, desirable snack behavior, and high MDA scores. The results indicated that the eating patterns of adolescent were not identical to existing diagnostic categories. Furthermore, each eating pattern displayed different characteristics of perception on self-body image, concern for weight control, and eating behavior. In conclusion, nutrition education for female middle school students could reflect the different characteristics of each eating disorder pattern.

The aim of this study was to determine the extent to which sociodemographic and health related life-style variables explain body weight distribution and to understand weight contol behavior. To study this study 298 students were selected, it was consisted of obesity group(101) and control group(197). The average age of subjects was 14.2 and the prevalence of obesity was 2-3 per class as 5.6% among 1,793. 71% among same subject was showed higher weight pattern than last one year, ovesity group which was obesity both in 93 and 94 was 34%. Correlation between body weight(under weight/obesity) and independent variables including sociodemographic factor and health- related life style tested through Multiple Classification Analysis was very significant, explained 36% of the total variance. Sociodemografic and hereditary factors such as education level, age of father and physical features of parents, life style factors as exercise preference and perceived health status showed highly contribution to body weight. Concretely, there were showed a higher obesity prevalence tendency when education level and age of father was high, physical features of parents was obesity. In otherwise, there were showed a higher underweight prevalence tendency when education level and age of father was low. Experience rates of weight control was 53% generally, 84% in obesity group, and 11% in underweight group. There were utilized weight control behaviors through diet method mainly in obesity group, diet and exercise methods in underweight group. There were showed that underweight group are prefer exercise to obesity group. Conclusionally, These findings suggest that education, age, physical features of parents, exercise preference and perceived health status is important factors related to body weight among middle school girls. Therefore, there will be considered as valuable factors when we practice health education and consultation related to body weight. Furthermore it is necessary to provide of various informations about weight control and to develop systematic weight control program.

Purpose: This study compared and analyzed the effect of the proprioceptive neuromuscular facilitation (PNF) arm extension pattern and leg flexion pattern on the contralateral lower extremity muscles when the patterns were applied to the same subject. Methods: In the study, 35 healthy men and women who understood the PNF patterns were selected as participants. The participants completed the PNF arm extension-abduction-internal rotation pattern and leg flexion-adduction-external rotation with knee flexion pattern in the supine position. While the patients' completed each pattern, the contralateral leg muscle activity was measured to examine the irradiation effect. The maximum isometric contraction time of the muscles to be measured was kept for 5 seconds, and the mean value was obtained by repeating the pattern three times. Results: When the leg flexion-adduction-external rotation with knee flexion pattern was completed, the muscle activity in the vastus lateralis, vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius of the contralateral lower extremity was significantly greater than that found in the PNF arm extension-abduction-internal rotation pattern. Conclusion: The PNF leg flexion pattern showed greater muscle activity on the contralateral lower extremity than the arm extension pattern. Thus, the PNF leg extension pattern is more effective in the activation of the muscles associated with weight-bearing activity.

In this paper, we present a new competitive learning algorithm called Dynamic Competitive Learning (DCL). DCL is a supervised learning method that dynamically generates output neurons and initializes automatically the weight vectors from training patterns. It introduces a new parameter called LOG (Limit of Grade) to decide whether an output neuron is created or not. If the class of at least one among the LOG number of nearest output neurons is the same as the class of the present training pattern, then DCL adjusts the weight vector associated with the output neuron to learn the pattern. If the classes of all the nearest output neurons are different from the class of the training pattern, a new output neuron is created and the given training pattern is used to initialize the weight vector of the created neuron. The proposed method is significantly different from the previous competitive learning algorithms in the point that the selected neuron for learning is not limited only to the winner and the output neurons are dynamically generated during the learning process. In addition, the proposed algorithm has a small number of parameters, which are easy to be determined and applied to real-world problems. Experimental results for pattern recognition of remote sensing data and handwritten numeral data indicate the superiority of DCL in comparison to the conventional competitive learning methods.

Maternal weight gain during pregnancy has been consistently associated with infant birth weight and pregnancy outcome. Our purpose was to determine the relationship between maternal weight gain pattern and birth weight. Consequently, maternal weight gain is monitored carefully and is encouraged during prenatal care in order to improve pregnancy outcome. Our study group included both 424 uncomplicated women and infant delivered at the Yeungnam University Hospital between 1993-1996. All recorded prenatal weight gain measurements were used to estimate maternal trimester weight gain, pattern of gain (based on low versus not-low gain at each trimester), and total gain at delivery. Multiple linear regression analysis was used to assess the relationship between these weight gain measurements and fetal birth weight. Each kilogram of maternal gain in the first, second, and third trimesters was associated with statistically related to the increase in fetal birth weight by 31.3, 19.0, and 24.5g, respectively. When compaired with the pattern of gain that was not low in any trimester, patterns with low gain in the first trimesters were associated with significant decreases in birth weight, but no important change in birth weight was seen for the group whose gains were not low in the first trimester. The results suggest that specific patterns of maternal weight gain, particularly weight gain during the first trimester, are related to fetal birth weight.

The diagnosis of pattern identification in Korean Medicine depend on Korean Medicine doctor's experience and information. So, Pattern identification in Korean Medicine raise a question of objectification. This study is to standard stroke pattern identification in Korean Medicine. Weight of symptoms was given important(1points), very important(2points) by stroke specialist. So weight of symptoms is used two method. One is total sum and the other is total man. One had been compared Pattern identification between diagnosed patients by medical specialists and by applicated weight in case report form. The other had been compared Pattern identification between intersubjectivity by medical specialists and by applicated weight in case report form. It is 38%(total sum) or 40%(total man) concordance rate between diagnosed patients by medical specialists and by applicated weight in case report form. It is 82.4% concordance rate between intersubjectivity by medical specialists and by applicated weight in case report form. To acquire more concrete data on this theme, we need further and large scale of prospective researches.

This study was undertaken establish the relationship between trypsin inhibitor in raw soybean and antinutritional effect of raw legumes. 1) Among legumes produced in Korea, Glycine max contains a relatively high amount of protein(higher than 40%) compared with kindey bean, sword bean and mung bean and, furthermore, soybean which contains a high amount of protein possesses high trypsin inhibitory activity. 2) Disc electrophoretic pattern exhibited pattern exhibited that the crude protein preparation from Glycine max produced about 9-12 protein bands, and the pattern of electrophoretic mobility was very similar to each other. However, only a few protein bands were observed from the crude protein preparation of yard long bean, sword bean, adzuki bean, mung bean and rice adzuki. From the eluate of the sliced gel, it was confirmed that among those bands, only the fastest moving band contains trypsin inhibitory activity. 3) In chicks fed the normal diet the body weight was increased steady from one week and reached to 40% increase for three weeks but in chick fed raw bean diet, there was no body weight gain until two weeks feeding and only 10-20% of body weight gain was observed at the end of three week feeding. On the other hand, in chicks fed raw bean diet the weight of pancreatic tissue per 100g body weight was increased to about two-fold for two or three weeks but there was no change in liver weight. 4) In the case of amylase secretion from the pancreatic fragment, very strong stimulation on amylase secretion from pancreatic tissue of chicks fed a normal diet was produced by one unit of cholecystokin-pancreozymin. However, no stimulation was observed from pancreatic fragment of chick fed raw bean diet.
