Participants in this study of the effect of story making activity on the language expression and creativity of young children were all forty 5-year-old children in a child-care facility. The experimental group read the fantasy picture book and engaged in story making activity; the control group read the same fantasy picture books the experimental group but didn't have any story making activity. Experimental treatments were given twice a week for 6 weeks. Data were analyzed by MANCOVA using scores of the pre-test as covariance. Differences were found between experimental and control groups in language expression and creativity showing that story making activity using the fantasy picture book was more effective than just reading without story making activity.

This study is to ascertain pre-service teachers' conceptions for the causes of season change, to verify their conceptional mistakes, and to analyze how their conceptions are changed while presenting Disproof-Experiment Model where they cannot explain it with their current conceptions. 32 junior students of Education universities, pre-service elementary teachers, located at the middle of Korea participated in this research including two interviews and one experiment activity. As a result of analyzing of the data, the pre-service teachers held diverse conceptions for the causes of season change such as to mistake the phenomena, the distance between the earth and the sun, the tilting of the rotation axis and the revolving around the sun while changing the tilting direction of the rotation axis as the cause. After applying Disproof-Experiment Model designed by the researchers in order to change the current conception above, the conception changes of the pre-service teachers were investigated. Diverse Disproof-Experiment Models were used differently depending on the pre-service teachers' conceptions. As a result of the application of Disproof-Experiment Model, 26 out of 28 pre-service teachers were changed to scientific conceptions. It was determined that in order to modify pre-service teachers' conceptions, designing and presenting the Disproof-Experiment Model appropriate to their conceptions are effective after analyzing their conceptions. In case of conceptions that pre-service teachers feel difficult, it was established that unraveling experiment models prescribed after investigating the preconceptions and identifying the misconceptions are important.

Background: The aim of this study was to investigate the effects of heel raising with kinesio taping (HRKT) on triceps surae muscle activity and balance in 20s adults. Design: Two groups pre-post randomized controlled design. Methods: The total of 40 subjects were randomly divided in the HRKT group (experimental group, n=21) and heel raising with sham kinesio taping (control group, n=19). Both groups receive heel raising with kinesio taping and sham kinesio taping for 20 minutes a day, five day per week, for four weeks. Measurement were performed before training and 4 weeks after training. The triceps surae muscle activity was measured using the EMG. A functional reach test (FRT) was used to evaluate balance ability. The independent t-test was conducted to compare exercise methods depending on the taping effect on each group. Results: The both group showed significant differences in muscle activity of lower extremity and functional reach test in the pre-post intervention comparison (p<0.05). The experimental group showed significantly more improvement in triceps surae muscle activity and functional reach test compared to the control group(p<0.05). Conclusion: We confirmed that the effects of heel-raising with kinesio taping group on triceps surae muscle activity and balance ability in 20s adults. The result suggest that heel raising with kinesio taping for 20s adults should be further studied and considered.

Studies till date suggest the existence of a fetal biological clock in suprachiasmatic nuclei entrained by the circadian signal from mother. Melatonin from maternal pineal gland reaches to the fetus by crossing every biological barrier including placenta, hence fetuses were exposed to similar melatonin variation as their mother. Experimental modulations of maternal pineal gland activity of pregnant females either by exposing the them to different photoperiodic schedules or by exogenous melatonin treatments till the date of parturition, regulated the fetal plasma level of melatonin, thereby the prenatal (fetal) growth and development. This clearly suggests the maternal transport of melatonin to their fetus through placenta since fetal retina-hypothalamic tract was incomplete. An extension of experimental schedules till 60 days of post-partum period regulated the neonatal pineal gland activity and gonadal maturation along with their plasma levels of melatonin and sex steroids suggesting clearly the phenomenon of maternal transfer of melatonin to their young ones during the post-natal period, when the neonates were solely dependent on the mother's milk for their nutrition and energetic demands. On the basis of above observations we may suggest that the maternal pineal gland activity regulate the prenatal development by passing its melatonin to fetus via placenta and post-natal growth and sexual maturation by passing maternal melatonin to neonates via milk. Hence, the photoperiod perceived by mother is translated into the maternal plasma level of melatonin which not only regulates the prenatal but also the post-natal growth and sexual maturation of neonates.

The purpose of this study was to examine the effect of listening to music during musical activities on children's development of tone recognition and sense of rhythm. The subjects were total sixty 4-years-olds from two classes of thirty. The children were divided into two groups, experimental and control. Before the experimental procedures, a pre-test was taken to evaluate the level of tone recognition and sense of rhythm of the children. Cordon's 'Audie' was employed and used to measure the difference of tone recognition and sense of rhythm. Then, the activity of listening to music was applied to the experimental group for ten weeks. For the experimental group, the musical activity was selected based on the themes of our tfe which was related to the weekly and yearly teaching plan. One the other hand, no musical activity was provided for the control group. After the experiment, a post-test was carried out using the same methodology of pre-test. Data were analysed by ANCOVA test. Results showed that there was a statistically significant difference in the development of tone recognition and sense of rhythm between the experimental group and the control group.

Purpose: This study was to identify factors to regular exercise among patients with osteoarthritis prior to total knee replacement. Methods: For this cross-sectional descriptive study, the data were collected using questionnaires from 136 patients scheduled for total knee replacement from July 2014 to December. This study aimed to analyse regular exercise status, intensity of physical activity, and factors affecting regular exercise. Results: Twenty two percent of patients expecting for total knee replacement are performing regular exercise and the intensity of it was very low. The use of walking aids, 6-minute walk test, self efficacy for exercise and pain, and quality of life (mental) were significantly associated with regular exercise before surgery. Factors affecting regular exercise were self efficacy for exercise (OR=1.059, CI=1.037-1.091) and 6 minutes walking distance (OR=1.007, CI=1.001-1.014). Conclusion: The results suggest that pre-surgery programs for physical activity and self efficacy were necessary for patients expecting total knee replacement. Regular exercise program could be beneficial for better outcomes after total knee replacement.

Tocopherols belong to the plant-derived poly phenolic compounds known for antioxidant functions in plants and animals. Activation of mitogen-activated protein kinases (MAPK) is a common reaction of plant cells in defense-related signal transduction pathways. We report a novel non-antioxidant function of ${\alpha}$-tocopherol in higher plants linking the physiological role of tocopherol with stress signalling pathways. Pre-incubation of a low concentration of $50{\mu}M$ ${\alpha}$-tocopherol negatively interferes with MAPK activation in elicitor-treated tobacco BY2 suspension culture cells and wounded tobacco leaves, whereas pre-incubated BY2 cells with ${\alpha}$-tocopherol phosphate did not show the inhibitory effect on stimuli-induced MAPK activation. The decreased MAPK activity was neither due to a direct inhibitory effect of ${\alpha}$-tocopherol nor due to the induction of an inhibitory or inactivating activity directly affecting MAPK activity. The data support that the target of ${\alpha}$-tocopherol negatively regulates an upstream component of the signaling pathways that leads to stress dependent MAPK activation.

The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)
