The purpose of this study was to investigate developmental tendencies and age-related differences in the relationship between children's cognitive and emotional perspective-taking ability. The subjects were 4-year-old (N=60), 6-year-old (N=60) and 8-year-old (N=60) children. In each group, there were an equal number of boys and girls. Feshbach & Roe's child perspective-taking ability test was modified for this study. The test included four facial expression cards and six different stories inducing three types of emotion: happy, sad and angry. This experiment consisted of a 3 (age) by 3 (emotional stories: happy, sad and angry) factorial design. The dependent measures were two response types: emotional and cognitive perspective-taking ability. The results showed that both cognitive and emotional perspective-taking ability increased with age. Happy emotional perspective-taking ability developed earlier than sad and angry perspective-taking ability. The correlation between cognitive and emotional perspective-taking ability increased with age.

This study examines the motivation, opportunity, and ability in the use of the internet by comparing young and aging consumers in the essential infrastructure of an information oriented society. Previous studies have conducted surveys about using computers and the internet instead of measuring the digital divide by using multilateral approaches; however, this study examines digital divide in terms of motivation, opportunity, and ability. Results suggested age, gender, and education level influenced motivation, opportunity, and ability in the use of the internet by consumers; in addition, the motivation and ability were different depending on occupation. The results show that the digital divide was mainly influenced by motivation and ability in offering a difference between the two groups of young and aging consumers, This study contributes to illuminate the differences between young and aging consumers to use the internet and to suggest implications in the perspectives of motivation, opportunity, and ability.

This paper deals with sensing ability of smart sensor that has a sensing ability to distinguish materials according to surface types of smart sensor. We have developed a new signal processing method that can distinguish among different materials. The smart sensor was developed for recognition of materials. We made two types of smart sensors in our experiment. Then, we estimated the ability to recognize objects according to smart sensor type. We estimated the sensing ability of smart sensor with the $R_{SAI}$ method. Experiments and analysis were executed to estimate the ability to recognize objects according to surface types of smart sensor. Sensing ability of smart sensors was evaluated relatively through a new $R_{SAI}$ method. Applications of smart sensors are for finding abnormal conditions of objects (auto-manufacturing), feeling of objects (medical product), robotics, safety diagnosis of structure, etc.etc.

In this paper, According to researches on the effectiveness analysis of digital textbooks for the last three years, it was turned out in digital textbook research school that learners' computer literacy is the most effective factor and the basic ability required to use digital textbooks. Therefore, in this paper, the effects of computer literacy on various factors were analyzed. For this purpose, after the level of learner's computer literacy was divided into upper, middle, and lower, and the effects of each level on cognitive aspects ability(problem solving ability, self-directed learning ability, and critical thinking ability) were analyzed. As a result, It turned out that the learner 's computer literacy has a close correlation with cognitive aspects ability(problem solving ability, self-directed learning ability, and critical thinking ability), and has a significant effect on cognitive aspects ability. In particular, the group with lower level of computer literacy had the greatest influence on the cognitive aspects ability, and the group with upper level had the greatest influence on the cognitive aspects ability in score improvement. Therefore, this paper suggests that various types of computer literacy education are needed to use effective digital textbooks.

Purpose: In real life there are both straight-paths and curved-paths. To evaluate walking ability of both kinds, a figure-8 walking test (F8WT) was developed. The aim of this study was to validate the measure in hemiplegic patients with walking difficulties and to identify correlations of curved walking ability with straight walking ability, motor function, and walking performance ability. Methods: Twenty subjects participated in this study. Curved walking was measured by a F8WT. Straight walking ability was measured by a 10-meter walking test (10MWT). Dynamic balancea bility was measured by timed up and go (TUG) tests. Walking performance ability was measured using a modified motor assessment scale (MMAS). Motor function was measured by the Fugl-Meyer assessment (FMA) scale. Data were analyzed using Pearson correlation analysis. Linear regression analyses were performed to explore other functional tests in mobility ability by F8WT time, 10MWT (dependent variable). Results: There was a significant positive correlation of F8WT time with 10MWT and TUG. There was a significant negative correlation of F8WT time with MMAS and FMA-coordination. There was a significant positive correlation of 10MWT with TUG. There was a significant negative correlation of 10MWT with MMAS and FMA-coordination. The F8WT time for curved walking ability was attributed to 10MWT for straight walking ability as 94% level of contribution. Conclusion: The results suggest that the F8WT is a good instrument for measuring walking ability because there is a robust correlation of F8WT time with 10MWT, TUG, MMAS, and FMA-coordination in hemiplegic patients who, after stroke, have a mobility deficiency.
