This study was performed to examine the flowing ability and filling ability of polypropylene fiber reinforced high performance concrete. The slump flow was decreased with increasing the polypropylene fiber content, rapidly. At the box-type filling ability, the difference of box height was increased with increasing the fiber content and the box-type passing ability was closed in fiber content 1 %. The final flowing distance of L-type was decreased with increasing the fiber content. Also, it was decreased above 0.75% of polypropylene fiber content, rapidly. The filling ability of L-type was badly showed above polypropylene fiber content 0.75%. Also, the compressive strength was decreased with increasing the fiber content, but the flexural strength was shown higher than that of the concrete without fiber. At the impact resistance, drop numbers for reaching in final fracture were increased with increasing the fiber content. Also, the drop numbers for reaching initial fracture of 1mm were increased with increasing the fiber content. At the acid resistance, the percent of original mass was decreased with increasing the fiber content.

Background: The purpose of this study was to present a practical method of medical treatment to improve the balance and motor ability of the mentally retarded child with a single mentally retarded child-subject. Methods: The subject of the study was a 39-month-old mentally retarded female. This study included a 2-week basic period and a 13-week treatment period. The treatment method was based on the Bobath Approach. Gross motor function measurement (GMFM) was used to examine changes in motor ability, and the Pediatric Balance Scale (PBS) was used to measure changes in balance ability. The curative program was composed of normalization of muscle tone, strengthening of leg endurance and muscular strength, the improvement of trunk alignment, and the increase of balance. Visual rate of change was used to examine the results. Results: As a result of this study, balance ability increased on the Pediatric Balance Scale (PBS) by 24 points, and motor function increased in terms of Gross Motor Function Measurement (GMFM) by 6.9% (18 points). Standing increased by 41% (16 points), and walking, running, and jumping increased by 31.9% (23 points) compared to thebasic period. Therefore, the Bobath Approach appears to be an appropriate method to improve balance and motor ability in mentally retarded children. Conclusion: It is surmised that aggressive intervention by physical therapists and occupational therapists, and a follow-up study, are required for the growth of motor ability in mentally retarded children.

This study is about the influence of middle school students' empathic ability on receptive attitude to students with disabilities. The questionnaire survey is used to measure cognitive, emotional empathy ability and the attitude of acceptance for students with disabilities targeting 300 students of middle school 2,3 grades. Empathy ability consists of 20 questions and the attitude of acceptance for students with disabilities is composed of 31 questions, which are three sub-areas like personal life, school life and learning activities. After subjects were divided into top 30%, middle 40% and bottom 30% according to their empathy ability, the attitude of acceptance for students with disabilities was measured. The results are as follows. There was a difference between groups in receptive attitude as a whole and the sub-areas. And the top group with high empathy ability had more acceptable attitude. In particular, there was a significant difference in the acceptance attitude for students with disabilities depending on the level of cognitive empathy ability rather than emotional empathy ability.

The purpose of this study was to investigate elementary school pupil's classification ability that appears in classification activity. For this study, we developed 2 suitable tools in classification activity achievement. One is artificial stimulus card that comes into view clearly. The other is natural stimulus card that does not come into view well. The test was administrated to 376 pupils of 2, 4, and 6 grade in D elementary School in Yeongdeungpo-gu, Seoul. The result proved in this study was as following. First, elementary school pupil's classification ability showed the developmental change as the grade level rises. Second, there was no statistical difference between boys and girls. Third, there was high correlation between sort artificial category and natural category in their ability. Fourth, classification achievement rate of constant level by grade was seen regardless of the items. The findings above gives following guidance in science classification learning. First, if teacher understands the development of students' classification ability, more effective classification guidance is available. Second, to cultivate students' classification ability, we should devise and apply program depending on their classification ability by grade.

According to the Korea National Statistical Office data in 2008, the population over ages of 65 years would possess to 10.7% whole population of Korea in 2009 denoting Korea is already in the aging society. It is well-known that the possibility to work longer and to live better is highly related to the work ability of individuals. The objective of this study is to evaluate the work ability of each aged group using the Work Ability Index(WAI) in the shipbuilding industry, machinery industry and Korea housing corporation, and to assess the effect of the type of business, age and job on the WAI score. The results showed that no significant difference was identified on the effect of aging although work ability of some group(over 55 years) was a little higher than that of others. Also, type of business and job had a significant effect on WAI score. These results suggested that the work ability is not necessarily related to aging in Korean society. One possible explanation for this might be different cultural characteristics of Korean society.
