The purpose of this study is to analyze the types of children's strategic thinking in the board games. Subject were 98 5-7-year-old children were participated in this study. Children divided by age were provided the same board game. Strategies used by the children to play the game were classified by age. The observational results were as follow; 1)Children used 9 strategies. Comparing to Kamii's study, children utilized 2 more strategic thinking. 2)Children used different game strategies based on children's age. Results showed that game strategies differentiated by child's age: five-year-olds used fewer strategies and older children applied a wider range of strategies.

This study analyzed the size of women in their 60s, 70s and 80s in the 2014 Human Body Dimension Survey data among Size Korea's 7th Human Dimension Survey Data in 2015. This study examined the characteristics of changes in female body shape according to aging and the age range. The height item gradually decreased from the 60s and then rapidly decreased to the 80s. In the case of the circumference item, a sharp change occurred in the section from 69 to 70 years old. The reduction in hip height, waist height, and navel level waist height was not significant compared to the decrease in stature. Both width, thickness, and circumference gradually decreased with age. It can be seen that the back bends forward and the legs become thinner than the body due to the aging phenomenon with increasing age. Even for older women, the characteristics of aging differ in their 60s, 70s and 80s, so age segmentation of silver clothing should be considered.

This study was performed to determine the voluntary range of joint mobility for middle-aged Korean adults. One hundred and eighty-eight subjects(99 males and 89 females) at the age range of 40 to 60 participated for this study. Thirty body movements at various joints were conducted to measure the range of joint mobility. Subjects were grouped by Rohrer's into four based on 25th percentile. The data were analyzed to see the differences of range of joint mobility between sexes and Rohrer's index groups. The results of this study and previous studies were compared to see the differences of range of joint mobility due to the aging. Results of this study indicate that females are generally more flexible than males. Significant differences were found to exist in fourteen movement between sexes and in ten movements, females have larger range of joint mobility than males. There were no significant differences in range of joint mobility may have a tendency to decrease with ages. The results of this study provide important information in dynamic dimensions for middle-aged Korean and can be used to design the various and work places for the middle-aged.

This study aims to investigate stereotype and effective cue presentation methods for burner-control relationship of four-stove range for Korean. A total of 381 subjects(male : 262, female : 119) were surveyed using questionnaire, in which eight gas range models drawn by 3-D Max 2010 were presented. The gas range models were labeled by signs(☆#${\triangle}{\square}$) to eliminate suggestive effect of sequential codes such as alphabets and numbers. The results showed that the stereotype was significantly affected by occupation(p < 0.10), but not by subjects' gender and age(p > 0.39). The stereotype of four-burner gas range for Korean was the same as that of Chinese, while the stereotype was different from that of American. The cues with rectangular-shaped arrangements identical or similar to those of burners were effective to relate burners to corresponding controls. The diamond-shaped cues and burner arrangements were not appropriate for representing burner-control relationship of four-stove gas range. These findings would be used as a basic guideline when designing four-burner gas range or similar equipments.

PURPOSE: The respiratory function and range of joint mobility deteriorate due to aging, respectively, and the respiratory function may be related to the range of joint mobility. To the best of the authors' knowledge, there has been little research on how the deterioration of the range of joint mobility caused by aging is related directly to the respiratory function. This study investigated the relationship between the respiratory function and the range of joint motion in the cervical and lumbar regions of older adults. METHODS: Thirty-two older adults participated in the study. The forced vital capacity (peak expiratory flow: PEF and forced expiratory volume in 1 second: FEV1) and the range of cervical joint motion were assessed in all subjects. The results were analyzed using the Pearson's correlation coefficient. RESULTS: The respiratory function moderately correlated with age. A moderate correlation was observed between FEV1 and right cervical lateral flexion. PEF was moderately correlated with the lumbar lateral flexion. In addition, FEV1 correlated strongly with lumbar lateral flexion. CONCLUSION: The respiratory function was correlated with the cervical and lumbar lateral flexion. Therefore, rehabilitation of the respiratory function should involve improving the limited range of motion of the joints, and a stretching program is needed for older adults.

This study was intended to analyze clothing preference images according to the age groups (30's, 40's, 50's and 60's) and to clarify the differences between present clothing preference images and that of the future after 60. The data was collected through a questionnaire and a total of 482 questionnaires on the age groups ranging from 30s through 60s were used in the analysis. As for the present clothing preference images in accordance with age groups, the younger age groups in the range of 30's and 40's presented higher scores in most of these images. But the older age groups in the 50's and 60's had lower scores in most of these images. On the contrary, the older age groups had higher scores than the younger age groups with respect to similar, mature, magnificent, innocent, plump and virtuous images. As for the future clothing preference images after 60 in the elegant, luxurious, graceful, intellectual, chic, urbane, slimy and sociable images, the age groups in the 30's and 40's presented higher scores than the age groups in the 50's and 60's did. However, with respect to the youth-oriented images such as fashionable, innocent, remarkable, cute and vigorous images, the age group in the 60's had a higher score than the age group in the 30's, 40's and 50's did. There were differences between the present clothing preference images and future clothing preference images after 60. The 30's and 40's presented distinctively different clothing preference images in the present and future after 60. Thus, distinct images were pursued in the older age group. The 50s showed closest images to that of the older age group, presenting more conservative inclination in clothing preferences.

Quartz schist - quartzite is often intercalated in metasedimentary rocks of Ogcheon belt or aligned parallel to the boundary between Yeongnam massif and Ogcheon belt. However, stratigraphic sequence and or geologic age of the rocks has been still variable among authors as Precambrian or Paleozoic. In this study, we carried out SHRIMP U-Pb age data of detrital zircons from Yeongam and Yeongsanpo areas and compared ours with other zircon ages from other areas. The detrital zircons from the studied area show no age younger than 1.8 Ga but yielded clusters at Neoarchean (2.5 Ga) and Paleoproterozoic (1.8 Ga). On the other hand, the age range of zircon U-Pb dating of Paleozoic quartzites yielded from Archean to middle Paleozoic and clusters at Paleoproterozoic, Neoproterozoic and Paleozoic. The characteristics of the zircon age range and the dominant age peak might become a key to classify the Proterozoic to Paleozoic quartz schists-quartzites, which ages are still remained under controversy. Based on the statistical results of the zircon ages in this study, quartz schist - quartzite from Yeongam and Yeongsanpo is considered to be deposited during Proterozoic.
