The 60 subjects of this study were 3rd, and 6th grade elementary and undergraduate university students. The instrument of 44 items had two typical and two atypical exemplars from 11 semantic categories. Each subject was exposed individually to the word list and asked to categorize each item. At test, subjects generated five items that came to mind in each category. Data was analyzed by 2-way ANOVA, age (3) $\times$ category of typicality (2). All main effects and the interaction effect between age and typicality were significant. There were no significant differences among age groups on typical lists while significant differences between university and elementary school students (Grades 3 and 6) were found on atypical lists. Thus, the knowledge base might be an important factor in implicit memory.

The purposes of this study were 1) to determine the relationship between antigravity control(supine flexion and prone extension) and postural control(static and dynamic balance) by age, 2) to determine the quality of antigravity and postural control, and 3) to determine whether sex difference correlates with differences in antigravity and postural control in young normal children. We tested 120 children aged 4 to 7 years. The study results showed a significant relationship between antigravity and postural control by age. Quality scale measurements(r=0.90) indicated that the children in this study had not yet developed full antigravity or postural control. The study results revealed differences between sexes(f>m in 5 of 7 tests) and a significant relationship by age in antigravity and postural control.

The purpose of this study was to compare the differences of weight-bearing distribution between subjects with low back pain and healthy subjects. Fifty-one subjects (22 men, 29 women; mean age = 42.9 years) with low back pain and 31 healthy subjects (11 men, 20 women; mean age = 35.4 years) were evaluated. The weight-bearing distribution was measured by two commercial scales during comfortable standing. The difference of weight-bearing distribution between right and left side was calculated for each subject. The differences of weight-bearing distribution in subjects with low back pain and healthy subjects were 6.0 kg and 4.5 kg, respectively. However, there were no significant differences in the weight-bearing distribution between subjects with low back pain and healthy subjects.

This study analyzed children's personality types with the use of the Murphy-Meisgeier Type Indicator for Children(MMTIC: adapted for Korea by Kim, 1993) and examined their relationship to the Torrance Tests of Creative Thinking(TTCT-figural, form A) and the Creative Personality Test(CPT: Yim,1997). Subjects were 210 third- and 218 sixth-grade students. Data were analyzed by one-way ANOVA and t-test. Personality types Sensation/Judgment(SJ), Sensation/Perceiving(SP), iNtuition/Thinking(NT) and iNtuition/Feeling(NF) differentiated the eleboration, originality, and flexibility dimensions of creative thinking. There were gender differences in the relation of personality type NF to elaboration and fluency. There were age differences in personality types SP and NF in relation to elaboration. Personality types differentiated between the independence, openness, attachment and adventurousness dimensions of the CPT. Age differences in personality type SP differentiated independence and type NT differentiated attachment dimensions of creative personality.

This study investigated differences of opinion between youth and their parents about having permission to date. Opinions on youth dating permission was gathered from 150 adolescents and their parents. The results were as follows: first, for adolescents there were significant differences of opinion about youth dating permission depending on gender, age, scholastic record, and birth order, but for parents, the difference related to the gender and age of adolescents. Second, the result indicated that adolescents had a greater acceptance of dating permission than their parents, expressing a generational difference. Third, where the scholastic record of subjects was low, where subjects were non-eldest siblings, and where the parents' level of youth dating permission was high, the level of youth dating permission was higher. A main predictor of youth's level of dating permission was the level of the parents about youth dating.

The purpose of this study was to investigate differences of Ca, Mg and Zn utilization in young and adult rats fed standard diet for 3 weeks. Feed intake and body weight gain in young rats were significantly higher than in adult. There were no significant differences in serum levels of Ca and Zn across age and sex. In liver of young or male groups, Ca and Zn contents were significantly higher than in adult or female. There were no significant differences in tibia contents of Ca and Mg, but Zn content was increased when young or female groups was compared with the other groups. In mineral balances, daily intakes and retentions of Ca, Mg and Zn in young or male groups were significantly higher than those in adult or female. According to this results, it could be suggested that in growth period must be increased dietary intake of Ca, Mg and Zn to compromise the requirement for growth.

This study aims to identify the obstacles to using interactive whiteboards for teachers of students with learning disabilities (LDs) in the Makkah region and to delineate any differences in the levels of these obstacles that can be attributed to the study variables: teachers' gender, academic qualifications, age, and years of experience. The researchers applied the descriptive survey approach to a sample of 123 teachers of LD students. To analyze the results, frequencies, averages, standard deviations, and relative weights were calculated. The results of the study indicated that the levels of the obstacles to using interactive whiteboards for teachers of LD students were moderate. No statistically significant differences in the levels of these obstacles were related to the variables of gender or age, whereas significant differences were found based on academic qualifications and years of experience.

Purpose: This study analyzed the perfume buying behavior of 561 men in their 20s and 30s. Research design, data and methodology: The demographic characteristics of the study subjects were analyzed frequently, the use of perfumes and chi-square tests were performed to identify differences in purchasing behavior, and the Likert 5-point scale was used to measure the importance of the reasons for choosing perfumes. Results: The most commonly used perfume product was Eau de Toilette, which had statistically significant differences with age and education (p<.05). Perfumes were most commonly purchased at health and beauty stores, with statistically significant differences by age, marital status, and education (p<.05). Conclusions: The study subjects have a high purchasing power for perfume products and are proficient in using smart devices, so they have a high level of information through beauty platforms, so they need to promote online products by introducing live commerce, etc.

This study was carried out to investigate the carcass characteristics of crossbred pigs according to mating system, carcass grade and age at marketing. A total of 656 pigs of 128 gilts and 528 barrows were collected and analyzed at public slaughter house. Differences between LY and LYD crossbred on marbling score and water holding capacity were significantly (p<0.05) found. The influences of LY and LYD crossbred on carcass weight, backfat thickness, meat colour, carcass grade and age at marketing were not significantly showed. The carcass weight of D carcass grade was significantly (p<0.05) heavier than that of the other grade. The backfat thickness was significantly (p<0.05) appeared gradually in accordance with the increase of carcass grade. There was significantly difference among the carcass grades on water holding capacity (p<0.05). The differences among the carcass grades on the meat colour, marbling score and age at marketing were not found significantly. The carcass weight of high age group at marketing was significantly heavier than that of the low age group (p<0.05). The backfat thickness of the group of high age at marketing was significantly thicker than that of the group of low age (p<0.05). There were significant differences among age group at marketing in marbling score, carcass grade, and water holding capacity, respectively (p<0.05). The carcass weight was positively correlated with the backfat thickness but negatively correlated with the carcass grade. The correlation between the backfat and carcass grade was significantly negative. The meat colour was negatively correlated with water holding capacity.
