The purpose of this study is to compare and analyze the amount of physical activity between young children with mental retardation and young children with normal condition using accelerometer. Six children (three children with retardation and other three children with normal condition) were selected as a subject on this research. And measurement of this research was done with the following items;(1)numpeaks accelerometer transverse; PAT, (2) numpeaks accelerometer longitudinal;PAL, (3)heat flux average original rate; HFA, (4) steps per minute(SPM), (5)GSR average. The amount of physical activity for young children with mental retardation shows that they move less that young children with normal condition; young children with mental retardation (PAT-$2.94{\pm}0.60$, PAL-$4.97{\pm}0.650$, young children with normal condition(PAT-$4.50{\pm}0.95$, and PAL-$6.05{\pm}0.87$). This suggests that young children with mental retardation lacks physical ability. And the amount of physical activity for young children with mental retardation was less compared with young children with normal condition. It is concluded that many programs for young children with mental retardation to have more interest and act fast should be introduced and developed in educating young children with mental retardation.

The distensibility of the major arteries has been investigated extensively, but the value expressed as Young Modulus varies widely by the different schools of the investigators, the major reason undoubtedly being the difficulties encountered in the measurement. In the present study, an attempt was made to elucidate the distensibility of the external carotid artery of the rabbit, which was placed in saline immediately after removing from the apparently healthy, normal rabbit without anesthesia. The circular section strip and longitudinal section strip were made from the whole artery, and Young Modulus of the whole artery, circular section and longitudinal section strips was calculated from the length-tension curve of each sample. Also, the similar samples of the artery seperately obtained were placed in ATP solution in the concentration of 0.15 mM and 0.30 mM, and Young Modulus was similary calculated. Experiments were performed at 15,45 and 75 min after the artery was removed from the rabbit, and the results thus obtained are summarized as follows. 1) Young Modulus of the whole external carotid artery of the rabbit in saline was $4.74{\times}10^7dyne/cm^2$ at 15 min, but lower values were obtained at 45 and 75 min, Young Modulus being $4.62{\times}10^7dyne/cm^2\;and\;4.13{\times}10^7dyne/cm^2$, respectively. When the arterial samples were placed in ATP solutions, Young Modulus did not change much throughout the experiment, and lower Young Moduli were obtained in 0.30 mM ATP solution than in 0. 15 mM ATP solution. 2) Young Modulus Of the Circular Section Strip in Saline was $4.11{\times}10^7dyne/Cm^2,\;3.75{\times}10^7dyne/cm^2\;and\;3.90{\times}10^7dyne/cm^2,$ respectively, at 15, 45 and 75 min, the value at 15 min being the highest. However, when the strip was placed in ATP solutions, no appreciable change was observed throughout the experiment, and Young Moduli were lower in 0.30 mM ATP solution than in 0.15 mM ATP solution. 3) Young Modulus of the longitudinal section strip in saline was $2.12{\times}10^7dyne/cm^2,\;2.48{\times}10^7dyne/cm^2\;and\;2.46{\times}10^7dyne/cm^2$, respectively, at 15, 45 and 75 min, Young Modulus being slightly elevated in the latter part of the experiment. A similar tendency was observed when the strip was placed in ATP solutions.

Not all parents are skilled in scaffolding their young children's numeracy learning. The present study investigated the effectiveness of a parent training program in promoting Filipino young children's number sense via card game playing at home. Participants were 161 young children and their parents; families were of a relatively low socioeconomic status. During the 10-week intervention period, parents in the experimental group received training on how to use number game cards to help their children acquire various numeracy concepts; parents in the control group received no special instructions. Children in the experimental group showed greater improvements in their performance on six number sense tasks (namely numeral identification, object counting, rote counting, missing number, numerical magnitude comparison, and addition) over the intervention period than did children in the control group. Findings of the present study suggest that providing simple training to parents on strategies for fostering their young children's number sense at home is important for giving children a good early start in basic number knowledge.

[Purpose] The purpose of this study was to comparatively investigate the correlation among body composition, resting metabolic rate (RMR), and physical activity (PA) between young and middle-aged Korean adults. [Methods] A total of 53 [male n=23, female n=30] subjects were included in this study, among whom 34 subjects were healthy young adults [male n=18, female n=16] and 19 were middle-aged adults [male n=5, female n=14]. The body composition and RMR of all the participants were measured after overnight fasting (≥8 h). The Korean version of the WHO Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity. [Results] Body composition was not significantly different between young adults and middle-aged adults. Whole-body bone mineral density and bone mineral contents (BMC) were significantly lower in middle-aged adults than in young adults. Total blood cholesterol (TC) and blood glucose levels were significantly higher in middle-aged adults (TC; 195.21 ± 43.34, glucose; 103.57 ± 12.61 mg/dL) than in young adults. RMR was significantly lower in middle-aged adults (1619.57 ± 290.28 kcal/day) than in young adults (1894.37 ± 405.00 kcal/day). In middle-aged adults physical activity (PA). PA (METs, min, EE) was inversely correlated with fat mass (FM, kg, and %) and blood triglyceride (TG) level in young adults. In middle-aged adults, PA showed a significant positive correlation with lean body mass (LBM), FM (%), and RMR. Furthermore, PA EE showed significant interrelatedness with BMC among middle-aged adults. [Conclusion] These results demonstrated that high PA levels enable LBM and RMR maintenance in middle-aged adults. Furthermore, in young adults, more PA is required to induce change in body composition.

Purpose: This study was conducted to investigate the correlation between anxiety and mastery in hospitalized young children's mothers. Methods: The subjects were 118 mothers of young children who were hospitalized in a pediatric unit. Self-report questionnaires were used to measure the variables of anxiety and mastery. In the data analysis, SPSSWIN 23.0 was used for descriptive statistics, Pearson's correlation coefficients and multiple regression. Results: The reliability of instruments were found to have a Cronbach's alpha of .84 to .92. Anxiety correlated negatively with mastery (r=-.43, p<.001) and positively with duration of hospitalization (r=.26, p=.004). In multiple regression, mastery and duration of hospitalization were significant predictors of anxiety in hospitalized young children's mothers, explaining 24.0%. Conclusions: Anxiety and mastery were significant variables in hospitalized young children's mothers. A strategy of nursing intervention which decreases anxiety in mothers must be developed by increasing the level of mastery in mothers of hospitalized young children.

The purpose of this study was to investigate the attitudes toward divorce of young men and women. The data were collected by questionnaire from 425 respondents who resided in Sunchon. Statistical methods for the data analysis were frequencies, one-way ANOVA, t-test. The data analysis revealed that the young men and women accepted divorce as an alternative to unhappy marriage and there were significant gender differences in the attitudes toward divorce. Women accepted divorce more positively as an alternative than men in every conditions. Men accepted divorce remarkably as an alternative to unfaithful debauchery of spouse, but women accepted divorce extremely well as an alternative to wrongdoing of spouse. Most of young men and women were worried about children, but not a few of them did not perceived themselves as child rearer. This results showed that divorce will be increased and perceived differently by gender. The young men and women who had lower conservative familism, who were younger, and who had higher education responded more positively about divorce.
