The purpose of this study was to examine mathematical performance predictions with gifted behavior ratings by teachers and parents. The participants of this study were 787 elementary 5th and 6th grade gifted students who took the mathematical performance test. This study asked gifted teachers and parents to rate gifted behaviors of these gifted students with using SRBCSS-R (Renzulli et al., 2002, 2009). The results indicated that gifted teachers rated gifted behaviors of the 5th grade gifted students higher than the 6th grade gifted students, except in 'mathematical characteristics.' Gifted teachers rated 'learning' gifted behaviors of male gifted students higher than those of female gifted students. In the meanwhile, parents of the 5th grade gifted students rated gifted behaviors higher than parents of the 6th grade gifted students in 'learning' and 'motivation.' In comparing the gifted behavior ratings by gifted teachers and parents, there were significant differences in 'learning' and 'motivation' ratings. That is, gifted teachers rated significantly higher 'learning' and 'motivation' of gifted students than parents. When this study explored the prediction of gifted behavior ratings by gifted teachers and parents on mathematical performances of gifted students, 'learning' and 'mathematical characteristics' ratings by gifted teachers predicted the mathematical performances of gifted students.

An anti-amnesic effect of water extract from Dendropanax morbifera Lev. leaves (DMW) on memory dysfunction in streptozotocin-induced diabetic rats was investigated to assess its potential industrial value. Daily administration of DMW (11 weeks) significantly reduced serum glucose, insulin, and blood urea nitrogen (BUN) levels increased by an intraperitoneal injection of streptozotocin (STZ, 55 mg/kg). In addition, the administration of DMW decreased escape latency and increased the time spent in the platform quadrant in the Morris water maze test. Step-through latency in a passive avoidance test was also improved. Finally, DMW produced ameliorating effects on STZ-induced cholinergic deficit through an inhibitory effect on acetylcholinesterase and the increment of acetylcholine level in the hippocampus. These results suggest that DMW might be used as a natural substance for improving diabetic induced cognitive impairment.

The intelligent disk can improve the overall performance of the I/O subsystem by processing the I/O operations in the disk side. At present time, however, realizing the intelligent disk seems to be impossible because of the limitation of the I/O subsystem and the lack of the backward compatibility with the traditional I/O interface scheme. In this paper, we proposed new model for the intelligent disk that dynamically optimizes the I/O subsystem using the information that is only related to the physical sector. In this way, the proposed model does not break the compatibility with the traditional I/O interface scheme. For these works, the boosting algorithm that upgrades a weak learner by repeating teaming is used. If the last learner classifies a recent I/O workload as the multimedia workload, the disk reads more sectors. Also, by embedding this functionality as a firmware or a embedded OS within the disk, the overall I/O subsystem can be operated more efficiently without the additional workload.

Nowadays, organizations have adopted Smart Work to efficiently manage tasks, such as electronic document approval, customer management, and site inspection, without spatial-temporal constraints. Smartphones, which are commonly used in Smart Work, enable individuals to perform their jobs anytime and anywhere, thus blurring the boundary between work and non-work. To solve the problem of blurred work/non-work boundaries, a construct of self-control and affective factors needs to be considered because business style is changed from command to autonomy in the Smart Work context. Moreover, employees can convey their emotions easily over smartphones. Recent marketing studies have analyzed consumers' behavior based on the combination of cognitive, affective, and behavioral components, and researchers of information systems are also interested in these factors. However, previous research has some limitations, such as not classifying factors into cognitive, affective, and behavioral as well as not covering all three factors. Therefore, we explore the roles of cognitive, affective, and behavioral components in emotional exhaustion and education performance, and conduct a survey on undergraduate and graduate students, who are the major users of smartphones. Findings show that when individuals improve their cognitive capability (self-control) and usage experience (smartphone communication and internet usage), they can decrease emotional exhaustion and increase education performance. In the role of affective capability, increasing education performance is partially accepted. These results imply that organizations should not focus on controlling the usage of smartphones but on promoting appropriate smartphone usage.

While growing interest about university education and quality enhancement, learner's scholastic achievement, learning process, various of learning activity work variable performance of university education. In this context, for quality enhancement of engineering education, it is necessary to pay attention not only learning achievement, educational conditions and environment, but also how students learn. The purpose of this study is checking learning activity in class of Engineering college students and proposing teaching and learning support for promoting learning activity in class. The result of this study is engineering college students were participate in highly only activity is called to professor, but self-directed learning engagements was less than. Activity of promoted thinking about task execution implemented frequently, but activity of critical thinking and applied everyday life were less than. In class students cooperated with colleague learner actively, they had sincere attitude about class. Based on these results, in order to promote learning activity in class, it is necessary sufficient teaching-learning support for learner's self-directed learning and enhancing thinking skills.

A performance evaluation, which requires to observe students in the course of learning and studying and to evaluate their reports and materials, is emerging as an alternative evaluation method to overcome the shortcoming of simple written tests. However, there are many difficulties in real teaching setting to apply the performance evaluation, because it requires many burdens of efforts and time. In order to reduce these burdens of teachers, there have been several approaches which utilize the Internet for the evaluation. But these previous approaches have several limitations that they don't allow students' participation in evaluation activities, fail to provide a variety of evaluation methods. and/or support teachers' feedbacks very limitedly. In order to overcome these limitations. therefore. this paper designed and implemented a web- based performance evaluation system supporting the participation of students in doing evaluation themselves and various evaluation methods. which can be effectively managed by teachers. This web-based performance evaluation system developed in this paper can enhance not only students' high level thinking abilities but also their emotional and intellectual abilities. It can also help teachers to reduce the burden of working and the time in plenty used for evaluating students.
